Therefore, you get pimples

Pimples and acne affect people, and most predominantly teenagers worldwide. Some may even scar for life, but most of us know how hard it can be even with the milder outbreaks of pimples.

The reason behind is bacteria in the skin, but genetic and hormonal factors also controls. For example, we hit extra hard at puberty because the testosterone level in the body increases, both the boys and girls.

But why some suffer a lot, while others may go through life completely spot-free? The question, researchers at the University of California responded, and now you think you have found the answer.

Good and bad bacteria
Scientists have looked into the genes of Propionibacterium acnes, the bacteria that cause facial problems. Just as in humans, there are small differences that separate bacteria ate, even if they are of the same species. And when the researchers detail studied these differences so they made an unexpected discovery.

We noticed that two variants of the bacteria could be linked to the occurrence of acne. And perhaps even more exciting was that we found a variant that could be linked to healthy skin, says Huiying Li, one of the researchers behind the study.

Different variants thus plays different role in our skin, and not all Propionibacterium acnes bacteria are evil.

Want to help people
According Huiying Li opens these results up many exciting new opportunities to help acne sufferers. 

One way to go is to develop some type of moisturizer that contains the "good" variant of the bacterium. Theoretically, then, a kind of cream to protect against the "evil" versions, just as different yogurt products and the like contain good magbakterier that keeps the bad guys away from your stomach.

Another way is to find ways to kill the evil variants without killing the good.

But it's a while until you have something there, and what is the best option, future studies in humans show. But Huiying Li hopes that such studies are not very far away in time.

The study now published in the Journal of Investigative Dermatology. 

 

Erection reveals the heart

It says scientists from the University of Sydney, Australia, after studying data from about 95,000 men who were part of an even larger health study. During the follow-up period expired the men who said they had problems with erections significantly higher risk of hospitalization for different types of heart problems - no matter how serious erection problems were. Compared with men without these problems, they had a higher risk of heart attack, heart failure, vascular disease and problems with the heart's electrical conductivity. To top it all, they had also a greater risk of dying from any cause.
The study, which is the largest of its kind, presented in PLOs Medicine Today.

Weakens excessive cleanliness our immune system?

Today we are much better for hygiene than before. The only good thing?

Not even very thorough cleanliness weakens the body's immune system, it is very important to avoid infectious diseases.

Hygiene is now much better than before, but at the same time, the number of allergy sufferers has exploded in the western world. It has given birth to a hypothesis that a sterile environment increases the risk of developing allergies, because the immune system is not kept in the form of such infectious diseases.

It therefore runs amok and react strongly to harmless substances. The hypothesis are not proven, and other studies suggest the contrary that such repeated influenza infections increase the risk of developing asthma.

Excipients make vaccines more effective

The vaccine is an ingenious invention, but in order to effectively prepare the immune system against diseases in the world many patients also undamaged, it is sufficient to fill the syringe with weakened microorganisms. The key to success today is to provide the vaccine with a range of customized power amplifiers.

Vaccines are one of medicine's greatest achievements. Doctors have saved countless lives by providing preventive renovate the immune system against pathogenic microorganisms. In this way it has been successful in eradicating smallpox and push back diseases like measles and polio so that they may be able to be completely eradicated.

A vaccine mimics an infection, so that the immune system reacts and then "remember" the disease, when the latter shows up in the body.

What exactly is fiber?

The fiber plant is a carbohydrate that can not be digested by humans, so it passes through the system are relatively intact and little or no calorific value.
There are two types of fiber: soluble (soluble in water) and insoluble (does not dissolve in water). Both play an important role in optimal health and naturally occurring - often together - in foods such as whole grains, fruits, vegetables, nuts, seeds and beans.
The fiber, soluble fiber, especially, also improves blood sugar control by lowering the rate that the stomach empties the food, which slows the rise in blood sugar after meals and avoid excessive insulin secretion or excessive. Delayed gastric emptying can also help you lose weight to improve control of hunger.
Women should consume about 25 grams of fiber per day and men should consume 38 grams. Most Americans have less than half of the recommended daily amount of fiber.
If you have trouble getting adequate amounts of fiber daily or intestinal problems or suffer from high cholesterol, talk to your doctor or nutritionist about adding a fiber supplement to your diet.
If you currently do not eat enough fiber, increase fiber intake slowly to avoid unpleasant intestinal symptoms (such as gas and bloating) and be sure to drink plenty of water.

Obesity can "lead to vitamin D deficiency"

The report, in the journal PLoS Medicine, analyzed data from 21 genetic studies - a total of 42,000 people.

They found each 10% increase in body mass index (BMI) - used as an indicator of body fat - led to a 4% decrease in available vitamin D in the body.

Since vitamin D is stored in the fatty tissue, the authors suggest a greater storage capacity in obese people can avoid circulating in the bloodstream.

The BMI is calculated as weight (in kg) divided by height (in meters) squared. People with a BMI of 30 or more is considered obese.

Lead author Dr. Elina Hypponen of the University College London Institute of Child Health, said the study "underlines the importance of monitoring and treatment of vitamin D deficiency in people who are overweight or obese."

Vitamin D is produced in the skin after exposure to sunlight and can be taken in supplements.

Sound levels are approximately 50 nanomoles per liter - less than 30 nanomoles per liter can cause softening and weakening of the bones, leading to rickets in children and osteomalacia in adults.

Professor David Haslam of the National Obesity Forum, said: "food intake and genetics play a role in obesity - but this research is a reminder that physical activity, like walking the dog or going out of the race in sunlight, should 't forget and can help correct the weight and lack of vitamin D "
