A new method of preventing viral infections, which is based on increasing the capacity of the natural mechanisms of protection body

The staff of the McGill University in Montreal, Canada, developed a new method of preventing viral infections, which is to increase the capacity of the natural mechanisms for the protection of the body. The researchers made inactive in mice two genes, the vast elaboration of interferon, protein, which is the first protective barrier cells against viruses.

A new method to improve the natural protective functions of the organism from the influenza virus and other infections found by Canadian researchers from the University of McGill, the Institute of Clinical Research of Montreal and the Research Institute of Health of Ottawa. The experts found that the suppression of two genes, 4E-BP1 and 4E-BP2, to improve levels of interferon, effectively blocking the virus from reproduction.

Viruses - microscopic infectious agents which adversely affect the cells and the human immune system, leading to illness and even death, explains Canadian specialists. Interferon, in particular the first type of interferon / IFN-945 and IFN-946; / prohibit the viral spread. Their production manages regulatory protein Irf7. Doctors found that the best way to activate a useful protein is the prohibition of the two genes found. Immunology hope that this discovery will lead to more reliable methods of protection of immunity from viruses.

HIV hides from drugs in gut lymphoid tissue
Existing drugs today are not able to completely destroy HIV in the human body. Deadly virus hides from drugs in various tanks, the most important of which is lymphoid tissue gut, American scientists found.

Specialists from the U.S. National Institute of Allergy and Infectious Diseases in Bethesda (Maryland) conducted a study involving eight patients suffering from HIV infection. All participants took anti-retroviral drugs for HIV within two to ten years, good feel and had a low viral load (low content of the virus in the blood).

Nevertheless, when studying samples of gut lymphoid tissue of patients taken during the biopsy, the scientists revealed the presence of HIV. The level of CD4 + cells that are targets for the virus, has also been below average. Researchers confirmed the similarity of DNA virus found in the gut, with the DNA of the HIV leukocytes. This indicated that the two tissues constantly infected one another after the virus replication, and that the intestinal reservoir is not isolated from other body tissues, said study leader Anthony Fauci.

According to scientists, it is very important to maximize early treatment of HIV because it will reduce the size of the reservoir virus from patients. The research results were published in the Journal of Infectious Diseases.

The relationship between weight and depression
A new U.S. study found that middle-aged women between weight and depression there is a relationship.

Scientists had collected information from 4641 women on the increase, weight, diet and physical activity.

The result showed that women suffering from depression twice as often suffer from excess weight (body mass index over 30) and women suffering from overweight, twice as often exposed to the depressed state. The link between weight and depression over remained strong even after took into account the factor of marital status, education, smoking and the use of antidepressants.

Depression and obesity are closely interconnected and feed off each other, feels chairing the study of Dr. Gregory Simon.

According to Gregory Simon, when people are recovering - it leads to oppression and depression them harder to something slimming. The label suffer from full rights lowers self-esteem and in turn the desire to lose weight.

Scientific Council for women suffering from obesity, raise self-esteem that will help them lose weight later.

It turned out that milk is useful not only for bones, but also for the muscles. Scientists have found that among young men, completing a power training session two glasses skimmed milk, muscle mass increased significantly more than those who drank soy beverages or carbohydrate. In addition, after 12 weeks of training they have lost more fat.

Kulturisty long ago started using the useful properties of the milk whey. Milk not only contains the same serums, but also a large number of proteins.

According to Stuart M. Phillips, the chief author of the study, amino acids found in milk in a very profitable quantities and ratios, which gives it advantages over drinks all the others. Milk protein assimilated better than soy, thanks to this muscle receive more amino acids.

The study involved 56 men aged 18 to 30 years. All of them were engaged in violent training 5 days a week for 12 weeks. Men from the first group drank a glass of skimmed milk immediately after the workout and another - within an hour. In the second group of participants had used soy drink that does not contain fat, in the third - a sports drink rich in carbohydrates. Calorie beverages do not differ.

All the men had increased muscle mass, but its biggest increase was observed in the first group. In the same group of men have lost the most fat. Researchers found no significant differences in muscle strength in men of the three groups.
The authors believe that increasing muscle mass and reduce the number of fat good for health, regardless of muscle strength. Muscle mass serves as a “depot” for glucose and fats, so-developed muscles can protect against such problems as obesity, type 2 diabetes, increased cholesterol levels.

The use of children low products and beverages contributes to overeating and obesity development, Canadian researchers claim.

Scientists from the University of Alberta (University of Alberta) conducted experiments on mice. Part of animals fed normal food, others - low versions of the same products.

It was found that young mice, feeding low substitutes often overeat. And were inclined to overeating as a painter, so thick and mouse. At the same time, older rodents, which gave dietetic food, do not overeat.

Adults beings have the ability to regulate the amount of calories consumed, based on their own taste sensations. The children, the ability of underdevelopment, and they are beginning to have more effort to compensate for low calorie foods, scientists believe.

“These data show us that children have a healthy useful, well-balanced diet with sufficient calories, rather than low snacks and meals”, - said study leader David Pierce.

Women who drank more than three cups of coffee a day are less prone to natural age weakening memory, the journal Neurology.

Scientists from the French National Institute for Health and Medical Research 7000 questioned senior volunteers on the amount they consumed coffee as well as to assess their cognitive abilities through tests. Repeated tests of cognitive abilities was held four years later.

It turned out that women over 65 years, daily drank more than three cups of coffee (or an equivalent amount of caffeine content of tea) memory test results vary slightly from the baseline, unlike those who drank less than one and cups of coffee daily. Favourable impact of coffee on the memory increases with age women. Coffee fan over 80 years to 70% less likely to suffer a decline of memory than their rovesnitsy, is not used aromatic drink.

Men relationship between coffee consumption and age decline in memory were found. “Women may be more susceptible to the effects of caffeine. Their body may react differently to the reception stimulator, and they may differ caffeine metabolism “, - said the study leader Karen Ritchie.

The study took into account all known factors that can affect the memory - the source age, education, arterial hypertension and other chronic diseases, receiving medications, etc.

In the future, scientists are planning a longer study. They have to determine whether caffeine can prevent the development of dementia, or just slows weakening of memory.
