Geneticists have taken another step toward a new HIV therapy

Researchers at Stanford University have developed the T-cells that are able to resist HIV, at least in the laboratory, says CBS San Francisco. According to the researchers, this discovery will bring gene therapy for AIDS.

In theory you could enhance any cells that attack HIV. As a result, the virus can not infect immune system. Taking into account that HIV mutates active and able to bypass the security mechanism of the body, scientists have tried to put several "obstacles."

Dr. Matthew Portias says: in the future, standard cocktail of antiretroviral drugs recede into the background. The idea is simple - therapy, which goes in with the use of a single injection.

Doctors will collect the patient's cells, change them, and then introduce back. That's the whole course of treatment. HIV nowhere to perch oneself, and the virus can live in the body. Biological mechanisms themselves will do the job and get rid of HIV.

Men spend less effort than women, if they need to lose weight

More difficult for women to lose weight. They have to put more effort to achieve the same result as the men. Scientists from the University of Missouri conducted an experiment. They gathered a group of obese men and women, accounting for them the same weight loss program, writes The Daily Mail.

Professor Jill Keneyli and colleagues tracked the heart rate and a pressure of about 75 people with Type II diabetes. People are offered a program of cardio for 16 weeks. Although all trained with a intensity of training to benefit more men.

Men threw off more pounds, and the recovery time after training decreased. Hence, men and women should train differently. The reason is simple - men have more muscles, and the muscles have higher metabolic rate than fat. Then, men more heart and lungs, as well as hemoglobin.

As a result, even at rest, men burn more calories. That is, men can just train, and women still need to follow the diet (men enough to train at 65%, as women - 85%)

Designed most optimal treatment for HIV

If a person starts to give medication immediately after diagnosis "HIV", it can slow down the process of infection, and began a lifelong course of drugs can be postponed, writes The Daily Mail. This, in turn, will reduce the chance of spreading the disease.
Meanwhile, patients usually do not prescribe antiretroviral therapy before their immune systems are seriously damaged. But a team from King's College London offers to give medication at once, in order to reduce the concentration of virus in the blood for up to 60 weeks.
Dr Sarah Fidler and colleagues studied 366 patients with HIV. Some of them were given for 12 weeks medication. The second group received 48 weeks of preparations. The third did not take drugs as long as the concentration of CD4 T cells was less than 350 cells per cubic milliliter of blood (normal concentration of 600 to 1200).
They then began to observe how long it takes for as long as the number of T-cells drop below 350. Another marker was the beginning of life-long course of antiretroviral drugs.
Group of patients received no medication, started life course through 157 weeks after infection. People taking antiretroviral drugs for 12 weeks - 184 weeks of infection. But here are taking medication for 48 weeks passed on lifelong therapy after an average of 222 weeks. And the concentration of T-cells was higher in the latter. Plus, reduce the risk of secondary infections such as tuberculosis.

Solariums dangerous midday sun twice

About the dangers of tanning salons for skin health, scientists say a long time. Now they have calculated the extent, said The Telegraph. American doctors have even tried to ban solarium minors.

It turns out that the risk of developing skin cancer is twice when people visit the solarium, compared with the same time spent in the midday sun in the Mediterranean. Experts in the person of Professor Harry Moseley of the University of Dundee to check the level of UV radiation at 400 solariums. 9 out of 10 gave higher figures of European safety standards.

Not for nothing, WHO brought it sunroom into a single list of factors triggering cancer with cigarettes. Over the past 30 years, the incidence of skin cancer has increased by four times. It is the most rapidly increasing rates of cancer in the group.

By the way, if a person under 35 goes to the solarium, the probability of melanoma increases by 87%. But independent experts emphasize that sounded data may not be relevant, because the payment was taken in the old statistics.

Cuba is in the grip of cholera, doctors warn

 In Havana recorded outbreak of cholera. The number of infected people to 51, reports Xinhua. Death yet. The first positive came to the attention of physicians on January 6. These were people who lived in the district of El Cerro and complained of severe diarrhea and vomiting.

Then cholera identified in other parts of the city. This is the second outbreak of cholera in Cuba for about six months. Despite this fact, Cuban experts argue that infection almost won.

Recall: in July 2011, epidemiologists cholera diagnosed in 158 people. Three died. Later it was decided to launch a nationwide campaign against cholera. Now doctors are engaged in active proliferation of drugs.

Cuban Institute of Tropical Medicine Pedro Kouri identified that the strain of cholera, which appeared on the island now, and is similar to the July. Recommendations to tourists and the local population are standard: hygiene, regular hand-washing and use only clean water.

The increasing pace of mental disorder pushes diabetics to death

The study showed women 53-100 years 1837, removal of the ovaries increases the likelihood of mental decline in old age, says The Independent. Removal is usually in young women due to cancer. Develops as a result of the operation "surgical menopause." With this type of one-third of the subjects experienced menopause. Women are tested for thinking and memory. It turned out "surgical menopause" at a young age was associated with a more rapid deterioration of the ability to think and certain types of memory. Long-term memory, coupled with the concepts, ideas, and episodic memory concerning any events - that suffer.

Commented research director Dr. Riley Bove, of Harvard Medical School: "Based on these data, we can assume that in this case it makes sense to turn to hormone replacement therapy. Actually, this is also indicated by the results of testing. Therapy can slow the process of deterioration."
