We hope you have been vaccinated with all vaccines, and to ensure that you are keeping yourself on the orbit of the checking the body regularly.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">

<span style="font-size: large;"><b>* Every Month you should do </b></span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">1. Self Breast Exams</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">While certain medical groups claim that self breast exams are no longer needed, many women have chosen to continue this practice. If you're not sure how to do a breast self exam already, learn the instructions, and be familiar with how your breasts feel and look. </span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">The test itself won't lower your risk, but having this performed regularly is putting you in the best position to see issues in the earliest stages.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">2. Self Skin Exam</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">If you have a propensity for sun spots or moles, you may have to go to your dermatologist more regularly, but The Skin Cancer Foundation recommends a simple head-to-toe self skin exam every month. </span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">The instructions are simple and easy to follow, and just like a self breast exam, it helps you get familiar with your skin so you notice changes earlier.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><b><br />* Every Year you should do </b></span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">3. Blood pressure testing </span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">Having your blood pressure checked every year is a necessity. Luckily, you don't have to head to the doctor every time you're due. Look out for screenings in your area or use the automated machines at your local pharmacy. High blood pressure - also known as hypertension - is 140/90 or above. The normal adult blood pressure should be below 120/80.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">4. Dental Exam</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">You may dislike heading to the dentist, but staying on top of this appointment is essential for your long-term health. Make sure you head for a thorough cleaning and dental exam every six months to a year.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><b>* Every Two Years you should do</b></span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">

<span style="font-size: large;">5. Eye Exam</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">The American Optometric Association recommends a comprehensive eye exam every two years. You'll take a series of vision tests to assess if you need glasses and also to check that your eyes are in good shape.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><b>* Every Three Years you should do </b></span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">6. Breast Exam</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">The breast exam performed by a physician is an important preventative measure to take to lower your breast cancer risk. According to the American Cancer Society, women in their 20s and 30s should have a clinical breast exam (CBE) every three years. </span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">While the majority of women don't have to start going for annual mammograms until their 40s, the ACA also recommends early mammogram screening for women with a first-degree relative who has had breast cancer.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><b>* Every Three to Five Years you should do </b></span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">7. Pap Smear</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">While yearly pap smears were the norm, according to the American College
of Obstetricians and Gynecologists, most women from age 21 to 65 can
wait three to five years between pap tests as long as the results are
normal.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><b>Every Five Years you neeed to do: </b></span></div>

<span style="font-size: large;">8. Physical Exam </span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">While certain studies are calling physical exams useless, the National Institute of Health still suggests getting two physical exams in your 20s and 30s. Every doctor is different when it comes to a physical, but chances are your provider will go over your history, vital signs, and blood work and perform a variety of medical screenings.</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">9. Cholesterol Check</span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">Once you're 20 years old, checking your cholesterol every five years is essential. </span></div>
<div style="font-family: Arial,Helvetica,sans-serif;">
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">The process is fairly straightforward; after you fast for 12 hours, you go for a blood test that measures total cholesterol, LDL "bad" cholesterol, HDL "good" cholesterol, and triglycerides. Your LDL cholesterol levels should be 100 mg/dL or less, and your HDL (good) cholesterol levels should be 60 mg/dL or above.</span></div>

Researchers are trying new approaches to treat Type 2 diabetes amid widespread uncertainty about the most effective therapies and concerns that current strategies might be doing some patients more harm than good. <br />
<br />
New guidelines for treating the disease, which many experts consider a public-health crisis among millions of mostly overweight individuals, suggest doctors vary treatments depending on a patient's age, general health and even personal preferences. The recently updated guidelines recommend that doctors back away from pushing patients to get their blood sugar down to a standard targeted level. Aiming for a very low blood-sugar level might be appropriate for a younger person, for example, while older patients might do better with a less aggressive approach, according to the guidelines, published in June in the journal Diabetes Care. <br />
<br />
'We need to be less dogmatic about what matters and be open to different approaches and give patients a voice' in treatment decisions, says Victor Montori, a diabetes specialist at Mayo Clinic, in Rochester, Minn., who wasn't involved with writing the guidelines but supports the new direction. <br />
<br />
Another approach gaining wider acceptance for some patients is the use of bariatric surgery, which results in dramatic weight loss. Though it comes with risk of serious complications, the operation has been shown in recent studies to lead to a rapid lowering of blood sugar, often enabling patients to go off most or all of their diabetes medicines. <br />
<br />
Some experts also are questioning the benefits of gradually stepping up the intensity of drug therapy, a widely accepted approach that was reaffirmed in the latest guidelines. The aim is to maintain a patient's blood-sugar level while keeping up with the progressive nature of the disease. But researchers at UT Southwestern Medical Center in Dallas, for instance, argue in a recent small study that hitting the disease early and hard is better. <br />
<br />
More than 24 million Americans have Type 2 diabetes, the version of the disease usually associated with being overweight and living a sedentary lifestyle. By some estimates the number could double by 2025. <br />
<br />
In diabetes, the body isn't able to effectively use insulin or to make enough of it to metabolize glucose in the food we eat, resulting in higher than normal levels of blood sugar. Heart attacks and strokes, kidney failure, nerve damage, blindness and vascular problems leading to amputation are among the long-term complications when the disease isn't well controlled. That makes diabetes a precursor to many of medicine's most debilitating conditions. Annual costs for treatment and loss of productivity associated with the disease are about $174 billion, according to the American Diabetes Association, an education and research association that devised the new treatment guidelines in collaboration with its counterpart the European Association for the Study of Diabetes. <br />
<br />
There have been conflicting findings over the benefits for patients of keeping blood sugar strictly controlled, helping to fuel uncertainty about how best to treat the disease. Some popular diabetes drugs come with side effects─including weight gain, bone loss and even a small risk of certain cancers. And some data have shown that aggressive efforts to achieve tight glucose control, until recently considered a desirable goal, can lead to troubling episodes of low blood sugar called hypoglycemia or to increased risk for serious heart-related problems. <br />
<br />
Although available drugs all improve blood-sugar levels, there is a lack of data to show whether they actually prevent or delay development of diabetes' long-term consequences. <br />
<br />
'The goal for treatment and the choice of individual drug must be personalized depending on the patient,' says Vivian Fonseca, the ADA's president for science and medicine and chief of endocrinology at Tulane University Health Sciences Center, in New Orleans. <br />
<br />
For most patients newly diagnosed with Type 2 diabetes, the first line of therapy is to improve diet and exercise habits to reduce blood-sugar levels. Usually metformin, a basic diabetes medication, is also prescribed. But patients with only mildly elevated blood-sugar levels may try to improve their health habits for up to six months to see if they can control the disease before beginning medication. <br />
<br />
Blood sugar is typically defined as being under control for diabetic patients when it is below 7%, using a measure known as hemoglobin A1c, or HbA1c, according to the ADA. Under the new guidelines, that level is still desirable. But younger, newly diagnosed and well-motivated patients with a long life expectancy may want to aim for even lower levels, closer to 6%, according to the recommendations. Such aggressive therapy is expected to better keep the disease from progressing. <br />
<br />
For older patients vulnerable to severe hypoglycemia or who may already have advanced cardiovascular disease, less stringent targets of up to 8% or even a little higher would be sufficient, the guidelines say. This also could reduce the burden of side effects from medications.<br />

The cause of ADHD, one of the most common developmental disorders diagnosed in children, isn't known.<br />
<br />
Researchers recorded irregular brain-wave patterns in children with attention deficit hyperactivity disorder, suggesting physiological abnormalities may be behind the condition, according to a report in Pediatrics and Neonatology. <br />
<br />
The study in Taiwan compared electrical brain activity in 50 children with ADHD and 51 controls during a test called Event-Related Potentials (ERP), which is used to study neurological disorders. The children, including 82 boys and 19 girls ranging in age from 6 to 13, were divided into four age groups for testing. None of the participants took ADHD medications.<br />
<br />
During the test, electrodes placed at specific sites on the scalp measured brain responses to 200 tones delivered at random sequences through earphones. When the children heard rare or odd-sounding tones, they pressed a button or counted the tones. The test was repeated twice for each participant.<br />
<br />
Results showed significant differences in the brain activity of ADHD children compared with the control subjects in regions of the brain associated with processing tasks requiring attention, processing speed, behavioral inhibition and control, and central nervous system hyperexcitability.<br />
<br />
The researchers said ERP could be a useful tool in identifying cognitive abnormalities in ADHD children.<br />

<b>Brief: </b>The researchers studied DNA in saliva contributed by 34 pairs of male identical twins, ages 21 to 55, and they found that they could estimate the ages of their saliva contributors to within five years.<br />
<br />
Saliva contains many useful components. Lubricants. Enzymes for breaking down food. And now, compounds that can reveal a person's age. That's according to a study in the journal Public Library of Science ONE.<br />
<br />
During normal development, DNA in your body gets what's called methylated. Small chemicals called methyl groups bind to the DNA, helping to determine which genes become active. But the patterns of methylation change as we grow older. Which was a clue that measuring methylation might give away age.<br />
<br />
The researchers studied DNA in saliva contributed by 34 pairs of male identical twins, ages 21 to 55. They found 88 sites on the men's DNA where the amount of methylation correlated with their ages. The scientists next verified that finding in 60 men and women, ages 18 to 70.<br />
<br />
Then they narrowed in on two genes that had the strongest age-related correlation. And using just that data, they found that they could estimate the ages of their saliva contributors to within five years.<br />
<br />
This technique might help in crime scene investigations -- recovered saliva could tell the age of a perpetrator. So if you're worried about anyone knowing how old you are, be careful where you spit.<br />

Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOXZXoVoLp73S8w2qn6nYpY66FjeygOHNeKzvgH8c9IBCLXkWV4SvIK3lN3WVmSOTLE-C-vyd2v_LEsSRyg9El60ivL9zs5qHM8EJp2GQwO8dy1f2dvlIqylskIi4jom-jumzHH0Wlr2dF/s1600/Top+Diagnosis.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOXZXoVoLp73S8w2qn6nYpY66FjeygOHNeKzvgH8c9IBCLXkWV4SvIK3lN3WVmSOTLE-C-vyd2v_LEsSRyg9El60ivL9zs5qHM8EJp2GQwO8dy1f2dvlIqylskIi4jom-jumzHH0Wlr2dF/s320/Top+Diagnosis.jpg" width="260" /></a></div>
<br />
<br />
The scientists told the Lancet that up to one in five of these students could experience severe visual impairment and even blindness. In the UK, the average level of myopia is between 20% and 30%.<br />
<br />
According to Professor Ian Morgan, who led this study and is from the Australian National University, 20-30% was once the average among people in South East Asia as well. "What we've done is written a review of all the evidence which suggests that something extraordinary has happened in east Asia in the last two generations," he told BBC News.<br />
<br />
"They've gone from something like 20% myopia in the population to well over 80%, heading for 90% in young adults, and as they get adult it will just spread through the population. It certainly poses a major health problem."<br />
<br />
<b>I: Lack of Outdoor Light</b><br />
<br />
Eye experts say that you are myopic if your vision is blurred beyond 2m (6.6ft). It is often caused by an elongation of the eyeball that happens when people are young. According to the research, the problem is being caused by a combination of factors - a commitment to education and lack of outdoor light.<br />
<br />
Professor Morgan argues that many children in South East Asia spend long hours studying at school and doing their homework. This in itself puts pressure on the eyes, but exposure to between two and three hours of daylight acts as a counterbalance and helps maintain healthy eyes.<br />
<br />
"We're talking about the need for two to three hours a day of outdoor light - it doesn't have to be massively sunny, we think the operating range is 10-20,000 lux, we're not sure about that - but that's perfectly achievable on a cloudy day in the UK."<br />
<br />
<b>II: Massive Pressures</b><br />
<br />
Cultural factors also seem to play a part. Across many parts of South East Asia, children often have a lunchtime nap. According to Professor Morgan they are missing out on prime light to prevent myopia.<br />
<br />
"Children suffer from a double whammy in South East Asia," says Professor Morgan. "As a result of massive educational pressures and the construction of a child's day, the amount of time they spend outside in bright light is minimised."<br />
<br />
A big concern is the numbers of students suffering from "high" myopia. According to Professor Morgan, this affects between 10% and 20% of students in Asian cities. It can lead to vision loss, visual impairment and even blindness.<br />
<br />
"These people are at considerable risk - sometimes people are not told about it and are just given more powerful glasses - they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help."<br />
<br />
For decades, researchers believed there was a strong genetic component to the condition. It was believed that people from China, Japan, Korea and other countries were particularly susceptible to developing myopia. But this study strongly suggests an alternative view.<br />
<br />
In Singapore, where there are large numbers of people from Chinese, Malay and Indian backgrounds, all three ethnic groups have seen a dramatic rise in short-sightedness. Professor Morgan says you cannot rule out genetics completely, but for him it's not the major factor.<br />
<br />
"Any type of simple genetic explanation just doesn't fit with that speed of change; gene pools just don't change in two generations. Whether it's a purely environmental effect or an environmental effect playing a sensitive genome, it really doesn't matter, the thing that's changed is not the gene pool - it's the environment."<br />

Now researchers are studing whether this surgery is also effective to those non-obesity diabetic patients.<br />

<br />
Cristina Iaboni, a diabetic, underwent gastric bypass surgery at New York-Presbyterian/Weill Cornell in the fall of 2009 as part of a study. After losing 50 pounds, her blood sugar was nearly normal. She is pictured here in June 2010.<br />
<br />
We've been hearing about health care law. Now, simply health care. Two studies released today address options for diabetics. They have found that surgical procedures commonly used to help obese people lose weight can also dramatically improve or even reverse diabetes.<br />
<br />
That may offer an alternative treatment for diabetics, as NPR's Rob Stein explains.<br />
<br />
Diabetes is one of the nation's biggest health problems and the disease is often caused by obesity. Diabetic Tim Ferree of Macedonia, Ohio, struggled with his weight for years. He knew his out-of-control blood sugar would eventually cause serious problems.<br />
<br />
You're looking at, you know, losing your vision, losing your feet, having problems with your kidneys, going blind, you know, heart disease, strokes.<br />
<br />
So when Ferree heard about an operation that might help with his weight and his diabetes, he volunteered to get it.<br />
<br />
With a brand new baby in the house, that's really what prompted me to take a very aggressive course towards treating the diabetes.<br />
<br />
Surgeons have been operating on obese people for years, making their stomachs smaller and rearranging their digestive systems. And doctors realized that patients who got the operations often had their diabetes get much better. Sometimes it even went away completely. But they didn't have good research that proved surgery was really effective.<br />
<br />
What's been lacking is a head-to-head comparison of surgery versus some of the newer anti-diabetic drugs.<br />
<br />
That's Philip R. Schauer of the Cleveland Clinic. He led one of the studies released today. The results showed that patients who got the operations were much more likely to have their blood sugar go down. Many were able to stop taking any diabetes drugs altogether.<br />
<br />
Just the fact we were able to see this many people achieve normal blood sugar without medications is somewhat astonishing. In a sense, we're reversing the disease.<br />
<br />
After the surgery, patients would sometimes get better within hours or days. And when that happens, its clear there's something more going on than just the effects of getting thinner. One theory is that re-arranging the digestive system affects important hormones.<br />
<br />
There appears to be an increased production of special hormones from the intestinal tract. And these hormones are know to directly stimulate the pancreas to make more insulin.<br />
<br />
And insulin controls blood sugar levels. This research raises an important question: Should diabetics start getting this operation more often? It's called bariatric surgery. Paul Zimmet of the International Diabetes Federation thinks they should.<br />
<br />
Diabetes coupled with obesity is probably the largest epidemic in human history. At the moment, bariatric surgery is being seen as a last resort. And it should be offered earlier in management.<br />
<br />
But others aren't so sure. The new studies only followed about 200 patients. And while the operations appear to be pretty safe, there can be complications. And the complications can be serious.<br />
<br />
Vivian Fonseca, a top scientist at the American Diabetes Association, said: I think we need longer-term follow-up than what was done in these studies, to make sure that you're not trading one problem for another.<br />
<br />
For his part, Tim Ferree is thankful. He's 60 pounds lighter. He's off all his drugs - not only for his diabetes, but also for blood pressure and cholesterol.<br />
<br />
I'm not staring down the barrel of being diabetic. I'm not looking at a future of potentially having to give myself several insulin shots every day. I'm not potentially looking at, you know, losing a foot or losing my eyesight or having a stroke. That's a great relief, I think, for anyone.<br />
<br />
Researchers are now testing whether the surgery works on diabetics who aren't even obese - people with BMIs as low as 26. And doctors and patients are waiting to see if insurance companies will pay for the operations just to treat diabetes.<br />

<br />
It is thought that her diet, the amount she exercises, whether she smokes or drinks alcohol and even which pollutants she is exposed to can alter the DNA of her unborn child. The changes are not to the letters of the code of life itself, but to its ‘punctuation’. These chemical marks can activate, silence or crank up genes and their actions.<br />
<br />
The latest evidence for the theory, which is known as epigenetics, comes from researchers at Newcastle University who analyzed the genes of children aged between nine and 11.<br />
<br />
They specifically looked for genes that had the same letters but behaved differently in children who were overweight and those who were slim. Blood samples stored since the children's births were then analyzed. This step showed that in many cases, youngsters who were overweight had displayed different chemical marks on their DNA at birth.<br />
<br />
Dr Caroline Relton, who led the research, said: ‘This suggests that our DNA could be marked before birth and these marks could predict our later body composition.’ Dr Relton, whose findings are detailed in the journal PLoS Medicine, does not know why some DNA is marked in the womb.<br />
<br />
But previous research suggests it is largely to do with the mother's lifestyle. However, Dr Relton added: ‘These marks are open to change. I think this puts the onus on the individual to do something about the way their genes work.’<br />

Now scientists from Sweden are working on a detection method, which can make pain "visible" for doctors in the absence of traumas.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
We all know what pain feels like, but it is not always easy to identify it.<br />
<br />
A broken bone and the effects of many diseases on the body can be seen. Unfortunately, it is not always possible to pinpoint the source of pain.<br />
<br />
But doctors here at Uppsala University say they have made an important achievement in the battle against pain.<br />
<br />
They are using positron emission tomography, or PET, scans which have been used in hospitals for almost a decade. A radioactive tracer is injected into the patient to develop a three-dimensional picture of the body. <br />
<br />
Researchers here say they have used it successfully to diagnose the origin of pain.<br />
<br />
They have mixed the usual radioactive tracer with a second substance called D-deprenyl, which they say attaches itself to the parts of the body where patients feel pain. Using the PET scans, researchers can develop images of the spots that indicate an uptake of the tracer mix.<br />
<br />
Lieuwe Appel specializes in diagnosing PET scans. Seated at his computer, he explains what appears on a screen before him.<br />
<br />
"Here we have a positron emission tomography picture. We call it a PET picture. It has been made with D-deprenyl that has been marked with Carbon-11. And here we can see a significant uptake of this tracer in this patient. They are the red marks on the screen, and this uptake corresponded with the area where the patient felt pain."<br />
<br />
Another lead researcher on the project is Dr. Torsten Gordh, Professor of Pain Medicine at Uppsala University Hospital.<br />
<br />
Gordh says the key to the research was finding the new tracer. He is convinced the researchers have found a substance which attaches itself to the spots where patients feel pain.<br />
<br />
Gordh says although some patients are almost disabled by pain, most scans fail to detect it, and that is why PET is vital.<br />
<br />
"With this PET method that we have developed we can actually see that there is an irritation where the patient feels pain. This is a very important tool when diagnosing the patient. The patient also gets a confirmation that something is wrong, and we get more basis for our methods when we work with the patient."<br />
<br />
Gordh says one of the driving forces behind the research has been the patients he has felt helpless to diagnose and treat.<br />
<br />
He says the research is deeply satisfying for him, because he believes he is closer to being able to make pain visible.<br />

Did you receive a gift from Santa Claus yet? This year Santa Claus brought us not only a real gift, but also give us its own experiences on five health lessons! The healthy gift, you have to receive a good strategy!<br />
<br />

<br />
<br />
Lesson 1: Stay up all night <br />
<br />
The only way for Santa to get the job done is to stay up all night on December 24 -- and that can lead to some serious health concerns. Sleep loss has a cumulative effect, and Santa has been working hard, likely cutting back on sleep, for the entire month preceding Christmas. As people lose sleep, they have problems responding quickly to specific objects.<br />
<br />
Lessons 2: Carring Heavy Sack Of Presents<br />
<br />
<br />
You should never carry something that weighs more than 10 percent of your body weight, especially when one shoulder is taking on most of the burden. In fact, doing so can cause back strains and sprains, muscle pulls, back spasms, difficulty walking and tingling and numbness down the arms and legs.<br />
<br />
<br />
Lesson 3: Obesity/Excess Weight<br />
<br />
The health risks linked to obesity are well-known, including, among others, Type 2 diabetes, coronary heart disease, stroke, hypertension, certain types of cancer and osteoarthritis. And belly fat, in particular, can cause serious health problems, especially among men. Belly fat can increase risk for insulin resistance, high triglycerides, heart disease and metabolic syndrome, among other problems -- most increased risk happens with a waist size over 40 inches.<br />
<br />
<br />
Lesson 4: Deficiency of Vitamin D<br />
<br />
Living with the short days in the North Pole, not to mention working the night shift in December, can cause a serious deficiency of Vitamin D, the sunshine vitamin, which has been linked to several health problems. Santa should aim to take a supplement that provides 1,000 IU of the nutrient. In addition, he should consider increasing his consumption of Vitamin D-rich foods, such as salmon or fortified milk.<br />
<br />
<br />
Lesson 5: Shift Work<br />
<br />
Santa's not alone here, more than 8 million Americans perform shift work, which has been linked with serious health problems, including cardiovascular disease, diabetes, ulcers and depression, among others.<br />

<br />
<br />
<b>Secret 1: 60% of the brain are Fat</b><br />
<br />
Yup, our brains are made up of 60 percent fat, says Dr. Michael Green, a research psychologist at Aston University.<br />
<br />
To function optimally, our brains need to maintain this level of fat. A lower amount of fat, in fact, can lead to neurological disorders. Dieters beware!<br />
<br />
<b>Secret 2: Our brains beed gut bacteria</b><br />
<br />
According to new research, the composition of gut bacteria can affect brain development and adult behavior.<br />
<br />
Gut bacteria can affect autoimmune diseases like multiple sclerosis as well as developmental disorders like autism.<br />
<br />
<b>Secret 3: Our brains also have an internal sense of direction </b><br />
<br />
According to new research carried out by the University of Massachusetts Medical School, humans may have an internal compass that allows them to navigate across the earth without an external device.<br />
<br />
The study found that monarch butterflies have an internal sense of direction that allowed them to get from one point to another even in the absence of light by sensing the Earth's magnetic field.<br />
<br />
Because we share a similar crypotochrome gene with monarch butterflies, it's possible that we have this magnetic sensing ability too. <br />
<br />
<b>Secret 4: Children's Brains are more active than Adults’</b><br />
<br />
Three-year-old brains are two-and-a-half times more active than adult brains, says a report by the California Early Childhood mentoring program.<br />
<br />
Because children are born with blank brains, each experience is completely new. In the first three years of his or her life, a child builds approximately 1 trillion synapses. <br />
<br />
<br />
<b>Secret 5: Our conclusion on time perception depending on how far the event is from us</b><br />
<br />
New research found that time perception changes depending on how close or far an event is from us.<br />
<br />

<br />
<br />
When our supplies of glucose - found in carbohydrates - drop we begin to lose our ability to control desire, while our urge to eat increases.<br />
<br />
The lack of glucose – which is used to power the brain – makes us helpless against the urge to reach for high-calorie foods, researchers said.<br />
<br />
Obese people are particularly vulnerable, with even the slightest drop in glucose prompting irresistible cravings for carbohydrates, from which we get most of our sugar.<br />
<br />
These can be "good" carbs, such as fresh fruit and vegetables, brown rice and pasta and wholemeal bread, or "bad" varieties which include white bread and sugar, fizzy drinks, cakes, crisps and other packet snacks.<br />
<br />
Making sure the brain's glucose levels do not drop could be the secret to staying slim, a study published in the Journal of Clinical Investigation suggested.<br />

Together, the needles are in a constant cycle of collecting and analyzing the blood of the patient it's attached to.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">You won't be able to feel it either according to its inventors, who say it's designed to stay permanently and painlessly in contact with a patient's arm.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">The technology, being developed at Swansea University, is in its infancy stage. The team is now in the middle of developing a transmitter which will be able to send an SMS message to a hospital, or to relatives as soon as a patient is at risk of a hypoglycemic attack.</span><br /><br /><span style="font-weight: normal;">The idea is to ensure that there is no delay in providing emergency treatment, even if the diabetic is alone and unconscious. Dr Vincent Teng is Swansea University's nano-technology expert.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">"The length of a needle is about 1mm and they have a diameter of about 15 microns. That offers a painless experience to a patient when using it. These needles will be attached to the arm of the patient and blood sample will be drawn using these micro-needles. The sensors, which are developed using nano-wire technology, will be integrated into the micro-needles, and that offers painless detection of blood glucose, and continuous monitoring of blood glucose."</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">An undetected hypoglycemic attack can prove fatal for people with type 1 diabetes. Sufferers need to take insulin injections, meaning they must test their blood glucose levels up to 10 times every day. Such a device would mean they wouldn't need to carry blood sugar testing equipment around with them at all times.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">The micro-needles are just part of the work from the University's Health Informatics Research laboratories, directed by Professor David Ford. He says the device being developed here is aimed at ensuring that diabetics are not at risk of fainting, or going into shock, when they're asleep, or alone.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">Ford says the system of continual monitoring is an exciting development.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">"If a patient was to wear this 24 hours a day it would be an enormous benefit in terms of understanding the way that their blood glucose responds to what they eat and what they do during the day, and potentially could have a role in perhaps automating the introduction of insulin into the bloodstream, which is the mechanism that is used naturally to moderate blood glucose levels."</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">This technology for diabetics is still a few years away from being tested. But Teng says that the team hopes the same system can be widened to provide pioneering care applications for people who suffer from heart disease and strokes.</span><br style="font-weight: normal;" /><br style="font-weight: normal;" /><span style="font-weight: normal;">"With the use of the right bio markers on the nano wires we'll be able to use this technology to detect other chronic diseases. Say, for example, heart disease, asthma, and also stroke, which is very common. In fact the number of people who suffer from this chronic disease has increased rapidly in recent times."</span><br /><br style="font-weight: normal;" /><span style="font-weight: normal;">The WHO says non-communicable diseases, or NCDs, are the leading cause of death in the world. That's 63 per cent of all deaths each year.</span></span></span></span></h1>

But for some of us it’s much more difficult than that – because of the way our brains are wired.<br /><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVcFXa_1UWj8-LYOLqxPYW6ivonv3i4jcVESLdyjeihR6EWYfeN0jhoh2Q9BkI4XxjUXylZkmV1ZtZfLD76YRH0JKtiXv_QFbMhNrR2OpjVhdbOocDC2Eymvor3bglEP5QanR1WOZui-tK/s1600/Temptation+of+Food.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 354px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVcFXa_1UWj8-LYOLqxPYW6ivonv3i4jcVESLdyjeihR6EWYfeN0jhoh2Q9BkI4XxjUXylZkmV1ZtZfLD76YRH0JKtiXv_QFbMhNrR2OpjVhdbOocDC2Eymvor3bglEP5QanR1WOZui-tK/s400/Temptation+of+Food.jpg" alt="" id="BLOGGER_PHOTO_ID_5655086363317288930" border="0" /></a><br /><br />Scientists have found that a key part of the brain which stops the body from acting on impulse – and gorging – does not function as well in those who are overweight or obese.<br /><br />A study by scientists from Yale University has shown that falling glucose levels lead to a loss of self-control in the brain which subsequently lead to parts of the brain craving high-calorie food such as cakes, biscuits or crisps.<br /><br /><br />In obese people the effect may be even more pronounced, so they are driven to eat by the slightest drop in glucose. Their uncontrollable cravings for treats are triggered by falls in blood sugar<br /><br />Glucose is normally obtained from carbohydrate foods, which can come in healthy and less healthy forms.<br /><br />Scientists believe the phenomenon occurs because of the brain's huge demand for glucose, which it needs as energy fuel.<br /><br />'Good' carbs include fresh fruit and vegetables, brown rice and pasta, nuts, wholemeal bread, and beans.<br /><br />Among the 'bad' varieties are white bread, white sugar, biscuits, cakes, crisps and other packet snacks, carbonated soft drinks, ice cream and corn syrup used in processed foods.<br /><br />Ensuring adequate brain glucose levels - in a healthy way - might make it easier to stay slim, the research suggests.<br /><br />“The key seems to be eating healthy foods that maintain glucose levels. The brain needs its food,” said Professor Rajita Sinha, from Yale University in the U.S., who led the study.<br /><br />The research is reported today in the Journal of Clinical Investigation.Prof Sinha's team manipulated blood sugar levels in a group of volunteers with intravenous injections of glucose.<br /><br />At the same time, participants underwent functional magnetic resonance imaging (fMRI) scans of their brains while being shown pictures of high-calorie and low-calorie food, and non-edible items.<br /><br />The scans showed that when glucose levels fell, two 'reward' regions of the brain that make certain activities pleasurable induce a desire to eat.<br /><br />But the most pronounced reaction was seen in the prefrontal cortex, the 'sensible' part of the brain that prevents people acting on impulse. When glucose levels lowered, the prefrontal cortex lost its ability to reign back the urgent 'eat' signals.<br /><br />* Originally Posted: <a href="http://www.topdiagnosis.com/2011/09/against-temptation-of-food.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-79004372516314904742011-08-15T00:35:00.000-07:002011-08-15T00:44:47.392-07:00In Infrared Light Everyone Looks Terrifying<b>Infrared Light</b> is emitted by an object because of what is happening at the atomic level. Using a typical camcorder, you can see the <b>infrared light</b> from a remote control.

<br /></a>Like humans, most animals rely on visible light for seeing, and plants rely on it for photosynthesis. In addition to the light that's visible to us, the sun also radiates ultraviolet and infrared light.
<br />
<br />
<br />Snakes have infrared sensors, and bees can see some ultraviolet light, but they're among the few exceptions to the rule. Why are we earth dwellers so attuned to visible light, instead of some other segment of the spectrum?
<br />
<br />
<br />Why don't we see ultraviolet or infrared?
<br />
<br />The traditional answer to this question was that most of the sun's radiation is visible light, so our eyes evolved to see those wavelengths. However, the sun also gives off a whole lot of infrared radiation. What would it be like if our eyes evolved to see infrared light?
<br />
<br />
<br />If we could see infrared, the sky would appear dark, and grass and trees very bright. Our veins would shine darkly through our skin, and warm blooded creatures would be very easy to spot. That would be a great advantage not only for predators on the prowl, but also escaping prey.
<br />
<br />
<br />What's visible light?
<br />
<br />No one knows for sure why animals and plants on earth evolved to perceive visible light, rather than infrared. One theory is that maybe there's no biochemical reaction that would allow us to translate infrared light into a visual image we can perceive, as we do with visible light. Or, maybe evolution just hasn't found it yet.

That’s according to a study in the Journal of School Nursing.<br /><br />"Quantifying School Officials’ Exposure to Bacterial Pathogens at Graduation Ceremonies Using Repeated Observational Measures", said Dave.<br /><br /><br />The researchers swabbed the palms of 14 school officials before and after graduation. They found that before the ceremony, and even after a slathering of sanitizer, hands were home to plenty of nonharmful bacteria. On the infectious scorecard, one dean brought Staph aureus to a commencement.<br /><br />Two others at a different ceremony walked away with it. And one of those samples came from a left hand, which didn’t participate in any of the meeting or greeting. So the math says that of more than 5,000 handshakes, just one may have passed along something less welcome than a sheepskin.<br /><br />So if you’re graduating this summer, don’t fear handshakes, it is not a big deal.<br /><br />Wait, while you wonder if the last person who wore that robe had anything contagious...<br /><br />* Originally Posted: <a href="http://www.topdiagnosis.com/2011/07/feel-free-to-shake-hands.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-3111605270972955632011-07-13T01:00:00.000-07:002011-07-13T01:09:48.915-07:00Now We’d Like to Vindicate for Bedwetting<span style="font-weight: bold; font-style: italic;">Guide: </span>Bed-wetting, this is not but a pleasant topic. Bedwetting now plagued 5,000,000-7,000,000 American children. If we can not explain why those children who are unluckily suffered from bedwetting bed, then let us at least to explore out the reasons for bed-wetting. Nowadays scientists believe that bedwetting is based on physiological factors, and some children suffer from common curable diseases or have structural defects.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9kmNB1pzrDD4e5Dx7hBaWda5E4WqdE4SkwBniKlykIQgWGqwLmwvb4AxlKthCOBS5yOI1YIRhZFYQM7WK-id38jw53Ai9omTmK_8rT-TScImXx1cqOeqapFL8H2pobHOvMyqzjDyHRMlP/s1600/Bedwetting+-+Top+Diagnosis.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9kmNB1pzrDD4e5Dx7hBaWda5E4WqdE4SkwBniKlykIQgWGqwLmwvb4AxlKthCOBS5yOI1YIRhZFYQM7WK-id38jw53Ai9omTmK_8rT-TScImXx1cqOeqapFL8H2pobHOvMyqzjDyHRMlP/s400/Bedwetting+-+Top+Diagnosis.jpg" alt="" id="BLOGGER_PHOTO_ID_5628744888072568578" border="0" /></a><br /><br />Never a happy topic, bed wetting is a very distressing problem for five to seven million American kids. If we can’t explain why some people like to pick on these kids, can we at least shed some light on what causes bed wetting?<br /><br />At one time, people punished bed-wetters for acting badly, but today scientists believe that this condition has several physical causes. Some kids suffer from problems like infections or anatomical defects that can be easily identified and treated.<br /><br />Other causes are harder to pin down. One promising area of research is on the kidney hormone ADH. We all produce more ADH hormone at night. ADH signals the kidney to slow down production. This is why we don’t go to the bathroom for eight hours at night but could never last that long between bathroom breaks during the day.<br /><br />Some children who wet their beds do not produce enough ADH at night. When given drugs that boost this hormone, they stop bed wetting.<br /><br />Finally, some kids simply have small bladders and an undeveloped nervous system. The good news is that these kids, like most bedwetters, will grow out of it as their bodies develop and mature.<br /><br />* Originally Posted: <a href="http://www.topdiagnosis.com/2011/07/now-wed-like-to-vindicate-for.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-77052024198709513292011-06-20T20:03:00.000-07:002011-06-20T20:32:19.125-07:00Be Careful of Your Mobile Phone!Recently, The WHO(World Health Organization) has added to the debate over the risk of brain cancer from mobile phone use. Last week the WHO's International Agency for Research on Cancer listed the signals from wireless devices as "possibly carcinogenic." This finding puts cell phones in the same risk group as the pesticide DDT -- but also in the same group as coffee. So, it seemed that when mobile phone take us convenience, the same time its dangers can not be ignored easily.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieZ6XOu0nTPtgKNoatquqNg05rHs09zKRnUcHZLvYjzuYz5Utt0-zoUl8IVdziUV7cqNGm7gihlWvyJ9yO1wmDQUYpavpWNo5TBW20nTl9rEKgHFybSllZJpgqFui-VEPsdWlNijMNp7gv/s1600/Be+Care+of+Your+Mobile+-+Top+Diagnosis.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 283px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEieZ6XOu0nTPtgKNoatquqNg05rHs09zKRnUcHZLvYjzuYz5Utt0-zoUl8IVdziUV7cqNGm7gihlWvyJ9yO1wmDQUYpavpWNo5TBW20nTl9rEKgHFybSllZJpgqFui-VEPsdWlNijMNp7gv/s400/Be+Care+of+Your+Mobile+-+Top+Diagnosis.jpg" alt="" id="BLOGGER_PHOTO_ID_5620507744934718978" border="0" /><br /></a><br />A group of thirty-one scientists from fourteen countries made the finding. The announcement came at the end of a meeting at the agency's headquarters in Lyon, France.<br /><br />The concern is that extended contact with radiofrequency electromagnetic fields may increase a user's risk for glioma. Glioma is the most common form of brain cancer.<br /><br />The scientists spent a week examining existing research. Dr. Jonathan Samet from the University of Southern California led the group.<br /><br />JONATHAN SAMAT: "We also carefully consider the sources of exposure of populations to radiofrequency electromagnetic fields, the nature of these fields as they come from various devices, including wireless phones, and we look carefully at the physical phenomenon by which exposure to such fields may perturb biological systems and lead to cancers."<br /><br />He says the finding that there could be some risk means scientists need to keep a close watch for a link between cell phones and cancer.<br /><br />The statement noted that the number of mobile phone users is large and growing, especially among young adults and children. Mobile phone subscriptions are estimated at five billion worldwide.<br /><br />The scientists called for more research into long-term, heavy use of mobile phones. They also suggested taking measures to reduce exposure to the signals, like hands-free devices or texting.<br /><br />Camilla Rees from an American group called Electromagnetic Health praised the report but says wider research is needed.<br /><br />CAMILLA REES: "We’ve only had this technology around for about fifteen years, and most carcinogens will take about several decades, thirty-forty years to develop a cancer. So based on some early indications, scientists are projecting that we’re actually going to be seeing a tsunami of brain cancer unless we do something to educate people to lower their exposure to this kind of risk."<br /><br />CTIA, the International Association for the Wireless Telecommunications Industry, dismissed the report. The group pointed out that no new research had been done. And it noted that the cancer research agency has given the same finding to things like coffee and pickled vegetables.<br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2011/06/be-careful-of-your-mobile.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-28857724691516599182011-05-23T00:34:00.000-07:002011-05-23T00:41:19.731-07:00Just How Big a Deal is Milk Drinking?<span style="font-weight: bold;">[Guide] </span>Recently, on the meeting of The Development of the Washington Association of Science, Sarah Waters Cove come from University of Pennsylvania pointed out that in fact, speaking for children and adults, when a type of protein called lactase expressed in the body, they can digest milk, body do not express this enzyme can not digest this complex sugar.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvJ4oTTYVyI4pTvA27PUK3b2YTfQZklspgmwsDQ_M2oWT3Nl78-CQA1cZfodXcnLO9ekIWXpo4pz87GhTty0KXFMgpoL7CPnUMIfnC6aSUtuC9rCl-wsJ4FGR-PvXKfA-omIwj8GeQskCV/s1600/Milk+Drinking+-+Top+Diagnosis.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhvJ4oTTYVyI4pTvA27PUK3b2YTfQZklspgmwsDQ_M2oWT3Nl78-CQA1cZfodXcnLO9ekIWXpo4pz87GhTty0KXFMgpoL7CPnUMIfnC6aSUtuC9rCl-wsJ4FGR-PvXKfA-omIwj8GeQskCV/s400/Milk+Drinking+-+Top+Diagnosis.jpg" alt="" id="BLOGGER_PHOTO_ID_5609812585905623330" border="0" /></a><br />“The ability to digest milk as adults, and as infants, actually, is due to the expression of an enzyme called lactase.” That’s the University of Pennsylvania’s Sarah Tishkoff at the AAAS conference in Washington, D.C., on February 20th, talking about the recent evolution of lactose tolerance in different human populations within the past 9,000 years. “Individuals who don’t express this enzyme can’t digest that complex sugar.”<br /><br />Can we put a number on the evolutionary importance of lactose tolerance? “The selective pressure was quite remarkable. We actually estimated it to be about 10 percent. So you’re more likely to have 10 percent more offspring essentially.”<br /><br />How strong is that? Look at population genetics to see how fast a trait will spread that develops in one individual in a population and that confers a 10 percent reproductive advantage. A mathematical analysis reveals that in just 100 generations, such a trait can be found in 95 percent of the individuals in the population.<br /><br />That time period could be less than 2,000 years for humans. “I’m often asked the question, are humans still evolving? I would say the answer is absolutely yes.”<br /><br />Now, maybe we cam say: Digesting milk is No longer a Problem?<br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2011/05/just-how-big-deal-is-milk-drinking.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-68180719702139099932011-04-18T01:42:00.000-07:002011-04-18T01:54:38.440-07:00New Results show Young Patients with Breast Cancer can Recovery Earlier<!--[if gte mso 9]><xml> <o:officedocumentsettings> <o:donotrelyoncss/> </o:OfficeDocumentSettings> </xml><![endif]--><!--[if gte mso 9]><xml> <w:worddocument> <w:view>Normal</w:View> <w:zoom>0</w:Zoom> <w:punctuationkerning/> <w:drawinggridverticalspacing>7.8 磅</w:DrawingGridVerticalSpacing> <w:displayhorizontaldrawinggridevery>0</w:DisplayHorizontalDrawingGridEvery> <w:displayverticaldrawinggridevery>2</w:DisplayVerticalDrawingGridEvery> <w:validateagainstschemas/> <w:saveifxmlinvalid>false</w:SaveIfXMLInvalid> <w:ignoremixedcontent>false</w:IgnoreMixedContent> <w:alwaysshowplaceholdertext>false</w:AlwaysShowPlaceholderText> <w:compatibility> <w:spaceforul/> <w:balancesinglebytedoublebytewidth/> <w:donotleavebackslashalone/> <w:ultrailspace/> <w:donotexpandshiftreturn/> <w:adjustlineheightintable/> <w:breakwrappedtables/> <w:snaptogridincell/> <w:wraptextwithpunct/> <w:useasianbreakrules/> <w:dontgrowautofit/> <w:usefelayout/> </w:Compatibility> <w:browserlevel>MicrosoftInternetExplorer4</w:BrowserLevel> </w:WordDocument> </xml><![endif]--><!--[if gte mso 9]><xml> <w:latentstyles deflockedstate="false" latentstylecount="156"> </w:LatentStyles> </xml><![endif]--><!--[if gte mso 10]> <style> /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} </style> <![endif]--><span style="color: rgb(40, 40, 40);font-size:100%;" ><span style="color: rgb(40, 40, 40);" lang="EN-US"><span style=""><span style="font-weight: bold;">Guide: </span>As we all know, breast cancer has been ones of major “killers” to many ladies, and the age women suffer the sick turn to more and more younger, recently, the latest medical research results show that early breast cancer can be found in young women earlier, so that they can be cured earlier, and more women can re-own a healthier body, as well as more happy times.<br /><br /><br /></span></span></span><span style="font-size:100%;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOjQEYFW8HYwKt0fXaX5YyCDJ35E_Ksw-Fc-BgiLwUK7CFyzsnQBDcA4GD-n5MJyDwZVLQeC5GORddJlePLZIo4nPptLxTuAfGVBWmMKmYJiv80XHJoVQT14hnnxrV2AJN1qvOj20C8XRx/s1600/Breast+Cancer.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 285px; height: 380px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOjQEYFW8HYwKt0fXaX5YyCDJ35E_Ksw-Fc-BgiLwUK7CFyzsnQBDcA4GD-n5MJyDwZVLQeC5GORddJlePLZIo4nPptLxTuAfGVBWmMKmYJiv80XHJoVQT14hnnxrV2AJN1qvOj20C8XRx/s400/Breast+Cancer.jpg" alt="" id="BLOGGER_PHOTO_ID_5596843018752214658" border="0" /></a></span><br /><p class="MsoNormal" style="font-family:arial;"><span style="color: rgb(40, 40, 40);font-size:100%;" ><span style="color: rgb(40, 40, 40);" lang="EN-US"><span style="">Have you ever felt lumps under the skin on the sides of your neck when you were sick?

But we also produce emotional tears. And it’s long been known that emotional tears are chemically different from poke-in-the-eye tears. Now researchers at the Weizmann Institute of Science in Israel find that women’s emotional tears have definite physiological effects on men. The work appears in the journal Science.<br /><br />The researchers knew that mouse tears contain pheromones that convey information to other mice. So they looked for similar kinds of signals in human tears.<br /><br />Two women volunteered to watch sad movies and have their tears collected. Twenty-four men were then asked to sniff the movie tears or a saline solution. The men noted no particular smell in either sample of salty water. But the men’s own body chemistry could tell the difference.<br /><br />When the men looked at emotionally neutral images of women’s faces after sniffing real tears, they reported less sexual attraction. The men also had lower levels of testosterone and less physiological arousal after smelling emotional tears compared with saline. Future studies will look at men’s tears, once researchers have collected enough videos of heartbreaking losses in big football games.<br /><br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2011/02/do-not-let-your-tears-with-him-at-night.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-960340328021549622011-01-13T00:02:00.000-08:002011-01-13T00:07:58.506-08:00Mobile Phones can Diagnose STD and Measuring Blood Pressure Soon<span style="font-weight: bold;">Guide: </span>Today, functions of mobile phone turn to more and more powerful, it is no longer just a convenient communication tool, all aspects in people’s living have close relations with mobiles, perhaps in the near future, mobile phones can help people to detect various diseases anywhere and anytime, which will be more conducive to help people to prevent and <a href="http://www.topdiagnosis.com/">diagnose</a> various diseases, thus produce more benefits to people's health.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKmZTY-cHYS-BO5uvu98XxFoJoBY-2QQAHkBmlkvM9jIVWVETJrDqTdJXS45N_h2iHmCNcik9kvOrz2DJYWMDH4aljGLpLXReZCaHNee0Jl2sF5iJc0TOARFToSZkOM7a6xN5A6ZeYA23m/s1600/New+Diagnosis+Tool.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 293px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKmZTY-cHYS-BO5uvu98XxFoJoBY-2QQAHkBmlkvM9jIVWVETJrDqTdJXS45N_h2iHmCNcik9kvOrz2DJYWMDH4aljGLpLXReZCaHNee0Jl2sF5iJc0TOARFToSZkOM7a6xN5A6ZeYA23m/s400/New+Diagnosis+Tool.jpg" alt="" id="BLOGGER_PHOTO_ID_5561578124041708850" border="0" /></a><br /><br /><br />Mobile phone technology is quickly changing the way the world operates. Today, we tell about two new projects involving mobile health, also known as m-health.<br /><br />Doctors and technology experts in London are developing a new way to test for sexual infections. The new device uses mobile phones and computers to help people find out if they have been infected with a sexual disease. People will be able to perform the test in the privacy of their own homes.<br /><br />People place urine or saliva on a small piece of paper. They place the test strip in a small device that contains a computer chip. Then they place the device in their mobile phone or a computer for testing.<br /><br />Within minutes, they receive information telling them if they have a sexual disease. And they receive advice on what to do next.<br /><br />Claudia Estcourt is with Barts and The London School of Medicine and Dentistry. She is also part of the research team working on the project.<br /><br />CLAUDIA ESTCOURT: "This isn't designed to replace traditional clinics. This is really opening testing up to people who might find it embarrassing or difficult to get into their clinic. And this might be a much quicker, easier option for them --- that they can be assured of very accurate results."<br /><br />Health experts say many young people are too ashamed to visit a clinic to be tested. This increases the risk of them passing on sexual diseases. The researchers hope the tests will help persuade people to be tested and reduce the number of sexually transmitted infections.<br /><br />Dr. Estcourt says the project is still seven to ten years away from completion. But she says it holds great promise for the future.<br /><br />CLAUDIA ESTCOURT: "Clearly one of the major implications of something like this would be for use in developing countries: maybe for testing HIV, maybe for testing for tuberculosis, or perhaps even malaria."<br /><br />Researchers at the University of Toronto in Canada are studying a mobile phone system that may help people with diabetes control their blood pressure.<br /><br />The system collects blood pressure readings from home testing devices that have wireless technology. The readings are then sent to a health-care monitoring system.<br /><br />Patients receive a mobile phone message telling them how they are doing. If their blood pressure is too high, they are advised to make an appointment with their doctor. Several high readings will cause the system to automatically contact the doctor.<br /><br />Patients in the study used the mobile phone system for one year. The researchers found that thirty-seven percent of the patients were able to get their blood pressure under control. This compares with about fourteen percent of patients using common equipment.<br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2011/01/mobile-phones-can-diagnose-std-and.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-45739102689746887232010-12-08T21:54:00.000-08:002010-12-08T22:06:57.872-08:00Cancer, Purely a Man-made Disease in Modern Society<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEghpnf4WZpC1ur1nDuVV245RJUhPWsn9fvsLMweYwKvkwvoVriUEhXFaaaR2VMHmb8DcWKagearUJdhDzd_LYC1LVfUkBJnHDXHMIoubO1DyDhWFAY6FEIhFcsVpSi_nX1wXCGEzPJYTuB6/s1600/Manmade+Disease+-+Cancer.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 200px; height: 199px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEghpnf4WZpC1ur1nDuVV245RJUhPWsn9fvsLMweYwKvkwvoVriUEhXFaaaR2VMHmb8DcWKagearUJdhDzd_LYC1LVfUkBJnHDXHMIoubO1DyDhWFAY6FEIhFcsVpSi_nX1wXCGEzPJYTuB6/s200/Manmade+Disease+-+Cancer.jpg" alt="" id="BLOGGER_PHOTO_ID_5548558383789975970" border="0" /></a>Is the common nature of cancer worldwide purely a man-made phenomenon. That is what some researchers now suggest.<br /><br />Cancer is a leading cause of death worldwide, however, scientists have only found one case of the disease in investigations of hundreds of Egyptian mummies, researcher Rosalie David of the University of Manchester in England said in a statement.<br /><br />"This might be related to the prevalence of carcinogens in modern societies," write Rosalie David and Michael Zimmermann of Villanova University, Pennsylvania. Cancers are "limited to societies that are affected by modern lifestyle issues, such as tobacco use and pollution resulting from industrialization".<br /><br />In a review of published analyses of tens of thousands of ancient skeletons and hundreds of mummies, David and Zimmermann found only a handful of cases of cancer. One recent finding, of colorectal cancer, was identified as the first ever discovered in a mummy. They also examined ancient texts and literature from Egypt and Greece, and say that there's little sign that cancer was a common ailment.<br /><br />A quote from David put out by the University of Manchester saying "there is nothing in the natural environment that can cause cancer. So it has to be a man-made disease, down to pollution and changes to our diet and lifestyle" caused particular consternation.<br /><br />Still, other specialists in cancer and in human fossils have strong doubts about this view. "Cancer is very rare in modern societies in humans under age 30," said oncologist John Glaspy at UCLA's Jonsson Comprehensive Cancer Center. "In ancient times, people rarely lived to be much older than that. So cancer was rare. The 'sin' of modern societies is having people live to be much older."<br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2010/12/cancer-purely-man-made-modern.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-26838914865226738072010-11-04T00:28:00.000-07:002010-11-04T00:34:14.722-07:00New Study: Lactate Level May Detect CNS Aging<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4Fp3RP9cwLYitGlFHpmKzx4OTYlUivPAXU41c3HJ8MqS1cMbNsCC2E9bULHVcYJE8pQRcwrJ_WKvN5SURalcHfBiwAaMGheb5YRtQURSnb-EVGa_M45fPIqNe1xYM7ek8u7Y21FqGzoxX/s1600/Lactate+Detect+CNS+Aging+-+Top+Diagnosis.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 300px; height: 215px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4Fp3RP9cwLYitGlFHpmKzx4OTYlUivPAXU41c3HJ8MqS1cMbNsCC2E9bULHVcYJE8pQRcwrJ_WKvN5SURalcHfBiwAaMGheb5YRtQURSnb-EVGa_M45fPIqNe1xYM7ek8u7Y21FqGzoxX/s320/Lactate+Detect+CNS+Aging+-+Top+Diagnosis.jpg" alt="" id="BLOGGER_PHOTO_ID_5535593775255352082" border="0" /></a>The study test on small mice found that, scientists may finally have the possibility to monitor the aging process of human through measuring the lactate level of the brain.<br /><br />Scientists have long suspected that it is the gradual damage of mitochondrial DNA (mtDNA) resulted in aging. But at present, there are few means to track symptomatic stages of CNS aging.<br /><br />Thus, although metabolic changes are implicated in mtDNA mutation-driven aging, the manifestations remain unclear. Here, we used normally aging and prematurely aging mtDNA mutator mice to establish a molecular link between mitochondrial dysfunction and abnormal metabolism in the aging process.<br /><br />Using proton magnetic resonance spectroscopy and HPLC, we found that brain lactate levels were increased twofold in both normally and prematurely aging mice during aging. To correlate the striking increase in lactate with tissue pathology, we investigated the respiratory chain enzymes and detected mitochondrial failure in key brain areas from both normally and prematurely aging mice.<br /><br />We used in situ hybridization to show that increased brain lactate levels were caused by a shift in transcriptional activities of the lactate dehydrogenases to promote pyruvate to lactate conversion. Separation of the five tetrameric lactate dehydrogenase (LDH) isoenzymes revealed an increase of those dominated by the Ldh-A product and a decrease of those rich in the Ldh-B product, which, in turn, increases pyruvate to lactate conversion. Spectrophotometric assays measuring LDH activity from the pyruvate and lactate sides of the reaction showed a higher pyruvate → lactate activity in the brain.<br /><br />We argue for the use of lactate proton magnetic resonance spectroscopy as a noninvasive strategy for monitoring this hallmark of the aging process. The mtDNA mutator mouse allows us to conclude that the increased LDH-A/LDH-B ratio causes high brain lactate levels, which, in turn, are predictive of aging phenotypes.<br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2010/11/lactate-level-may-detect-cns-aging.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0tag:blogger.com,1999:blog-8094684573529792004.post-13220979178847741952010-10-10T22:35:00.000-07:002010-10-10T23:07:26.897-07:00Taking Too Much Soft Drinks May Speed Up Aging<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhUZGbiHrVPBdkBeZrgxXzbKqOD0yp9GrpyAxiWHirl14bbI7NmtzL3hb8mpinPHUXEsKiNtg32CVM5pJolveT-sjrwISfMV9o2Rq3OjRxHEUKiA7ZxkdmY2vlt51RldOrI_CPXDCidGkiM/s1600/Soft+Drinks.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 210px; height: 210px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhUZGbiHrVPBdkBeZrgxXzbKqOD0yp9GrpyAxiWHirl14bbI7NmtzL3hb8mpinPHUXEsKiNtg32CVM5pJolveT-sjrwISfMV9o2Rq3OjRxHEUKiA7ZxkdmY2vlt51RldOrI_CPXDCidGkiM/s400/Soft+Drinks.jpg" alt="" id="BLOGGER_PHOTO_ID_5526665399949797090" border="0" /></a>Aside from being damaging for our figure and our bones, it turns out that fizzy drinks are also bad for our skin, for they contain phosphate, which speeds up the aging process, a recent study cited.<br /><br />The study reported :“Research shows that soft drinks may not only break our body fit, damages our bones, but also hurt our skins, which is because phosphate, which gives many soft drinks their tangy taste, can accelerate ageing”.<br /><br />The findings of the study shows that the mineral, phosphate, which is also added to processed meats, cakes and breads, was found to make the skin and muscles wither and could also damage the heart and kidneys. Although the experiments were carried out in mice only, the researchers from Harvard University believe the results show the potential consequences of high doses of the mineral” .<br /><br />“Humans need a healthy diet and keeping the balance of phosphate in the diet may be important for a healthy life and longevity. Avoid phosphate toxicity and enjoy a healthy life.” Researchers said additionally.<br /><br />Originally Posted: <a href="http://www.topdiagnosis.com/2010/10/taking-too-much-soft-drinks-may-speed.html">Top Diagnosis</a>Sebastian Coehttp://www.blogger.com/profile/04972715648751520151noreply@blogger.com0
