To be happy to help a sincere smile, to bring about positive thoughts, say researchers from the University of Michigan business in the U.S.. According to them, a fake smile affects mood and performance, and sincere, conversely, improve something, and more.
Often when working with clients from a specialist requires a constant smile on his face, but this practice leads to emotional exhaustion and, ultimately, adversely affects the quality of work. In order to test the effect on the performance of the smile, the experts have chosen a group of drivers of buses, monitored by two weeks.
Part of the volunteers had to smile "on duty" smile, the other - constantly thinking about nice things or remember something positive, to smile. As it turned out, insincere smile worst effect on women - they are upset and became worse faster than men in the same situation. Conversely, a sincere smile affects a woman's health better and faster than men's.
According to the authors, this effect is due to the fact that women's emotions are always more intense, and any falsehood in them causes the female internal conflict, leading to a deterioration of health. Nevertheless, scholars believe that the principle of "think positive" can help improve mood and performance for at least several hours for both men and women.

Influenza retreats
The incidence of influenza and SARS is gradually declining. Talking about it and the oversight agencies, and urban hospitals. "Index of influenza, the calculated" Fontanka "is also on the decline: antivirals will cost townspeople this week a little cheaper than last. Experts believe that such rates may stabilize the situation by the end of next week.
Influenza is slowly receding. According to the St. Petersburg Rospotrebnadzor on 17 February, the city registered 9,000 people to seek medical advice (it's a thousand less than last week). The same number, incidentally, is, and the epidemic threshold.
Infant morbidity, according to the Education Committee, also on the decline. To date, close to 278 classes of two children's institutions of the Kalinin and Nevsky districts. Recall that last week because of quarantine for influenza and SARS have been closed 602 class at 9 schools.
Reducing the incidence of confirmed and specialists urban infectious diseases hospital Botkin. "We have really began to receive fewer patients. - Said "Fontanka" the chief doctor of the hospital Alexei Yakovlev. - Of course, the situation is still kept at the level of the epidemic, but there is a tendency to decline. "
Now the city recorded six fatal cases of swine flu. In the past year, according to the main infectious diseases of the Health Committee of city administration, in St. Petersburg was recorded 30 deaths from the virus AH1 N1. In Rospotrebnadzor note that this is one of the worst forms of influenza.
But the buzz in drugstores, such as at the peak of the epidemic last year, no. How can I ensure correspondent Fontanka, all antiviral drugs are available. Only the powder for inhalation "Relenza", as we have already mentioned, best to book through an online pharmacy or over the phone - in the shops it is not always.
One of the most popular drugs, "Arbidol, sold in all dosages. Recall that last week there were just big bags cost from 695 to 749 rubles.
Recommended by the World Health Organization "Tamiflu" at a price has not changed. Minimum the cost is 1,150 rubles. Price tincture of calendula, too, rests on the same mark for two weeks. The pharmacy can be purchased for 8.5 rubles. But the spray from the cold "Nazol and homeopathic remedy" Otsillokoktsinum "fell by 32% and 9.7% respectively.
Masks also have a free market. For 3.5 rubles can buy the most simple gauze, and for 9 rubles - a three-layered.
Index Flu "(obtained by calculating the arithmetic mean of the amount spent from St. Petersburg to all 8 major drugs that are recommended for use in the influenza period: Arbidol", "Remantadin, Tamiflu, Relenza," Otsillokoktsinum " "Ferveks", "Nazol and tincture of calendula) in comparison with last week also went on a slight decline. "Medication Basket townspeople now cost about 5% cheaper.

The immune system goes crazy from the sun
Intense sunburn causes the immune system to grow cancer cells, say scientists from yniversiteta George Washington in the USA. Researchers now know why sunburn provoke the development of melanoma - one of the most deadly forms of skin cancer.
A team of scientists led by Dr. Edward de Fabo conducted a series of experiments on laboratory mice and found that when exposed to ultraviolet B-type run specific processes in the immune system.
Macrophages are white blood cells migrate to the superficial layers of the skin and produce immune proteins, called interferon-Y. But instead of protecting the body, as it should be all interferons, type Y can grow cancerous tumors by preventing the natural immune response to it.
"We did not expect to see the IFN-Y as an accomplice in the development of cancer - said De Fabo - he must kill her." Scientists believe that their discovery will help in the creation of new drugs against melanoma, and again warned of the dangers of excessive tanning. Indeed, until the immune system to prevent sunburn is impossible.

Lifestyle has the greatest influence on its duration
Life expectancy of your parents or grandparents are not guarantees of personal longevity: a factor in personal lifestyle plays a more important role in maintaining health for many years than genetics, according to Swedish researchers University of Gothenburg. Hereditary factors play a major role in determining the length of life, since life has a big impact, according to clinicians. Doctors refer to these long-term survey of almost 2 thousand men.
Observed that those who do not smoke, consume moderate doses of coffee and have a good socio-economic status at age 50, and has a good physical performance at the age of 54 years and has a low level of cholesterol in midlife, had the best chance to celebrate their 90 th anniversary. Our own lifestyle and habits lay the foundation for our longevity, which is not inherited automatically, convinced doctors.

February 4 - World Cancer Day
February 4 - World Cancer Day. By this date, scientists have prepared the good news: in the first MGMU them. Sechenov developed a vaccine against cancer.
The vaccine is designed to treat already infected, rather than preventive health care. But first things first. No wonder they say: people with cancer die not from disease but from the treatment. Strong antitumor drugs often kill not only cancer but also healthy cells. But there is a safer approach - do not veer rights "poison", and make the immune system to fight the disease. As her whip and incite a tumor? On this question the scientists until recently had no answer. For example, when the virus enters the cell, it finally collapses, go out proteins that contain information about him, and, as on a silver platter, presented with this information the immune system.
She thought: "Aha, here the virus. We must kill him. " Treachery of tumor cells that information about it or do not leak out or pops up in part. Therefore, the immune system may miss the enemy, not even trying to compete with him. Hence, scientists have decided you need this information to convey to the immune system. From the tumor have been providing proteins that contain information about it, and enter back person.
Such developments in the U.S. began back in the 80's. Twentieth century. A recently published the results of tests on patients. Vaccine to cope with the tumor better than chemotherapy, did not cause severe disorders in other organs, but ... There were two problems. First: the vaccine were able to cook for only 50% of patients who participated in the study. If the tumor is small, then the right amount of drugs out of it can be done.
Second: the reason for the same cancer, say, a kidney, a severe vaccine works great, with average does not help at all, and when the lungs again effective. Russian scientists were able to circumvent these restrictions. They suggested: the vaccine does not always work, because information on the tumor is removed, not all. Proteins that hoarding "dirt" on her and that Americans are isolated from the tumor, made artificially. Thus decided to both problems.
According to the Russian method to get the same amount of vaccine required is 4 times smaller amount of tumor tissue. The experiments showed that: a new drug significantly reduces the growth of melanoma, prostate cancer and breast cancer. And there is real hope that very soon it can be applied to patients.
