Inability to control negative emotions increases time of healing - such are conclusions of employees of the State University of Ohio as a result of experiment with participation of 98 volunteers.

As it was found out, wounds on hands of irritable people healed much more slowly in comparison with easy-tempered participants. The researchers took into account such factors as duration of sleep, physical activity and drinking alcohol.

Authors of the research consider, the slowed down healing of wounds can be connected to the increased level of cortisol. Scientists mark also, that their data are proved to be true by results of the previous researches.

The report about an experiment is published in magazine The Brain Behavior and Immunity.

New American research has shown that there is connection between excess weight and depression in middle-aged woman.

Scientists have collected the information about growth, weight, diet and physical activity of 4641 women.

In result they have found out that women suffering from depression, twice more often suffer from excess weight, and women suffering from excess weight, twice more often are subject to a depression. Connection between excess weight and depression remained strong even taking into account marital status, education, smoking and taking antidepressants.

Depression and fatness are closely interconnected and inject each other, considers Gregory Simon, head of the research.

In Gregory Simon’s opinion, putting on the weight leads to depression, and being in depression it is more difficult to do something for growing thin. The stout label lowers self-respect and desire to grow thin.

The statement that intellectual faculties of the person depend on heredity has been ruthlessly denied. The group of American psychologists and doctors within several years studied influence of an environment upon development of person’s intellect.

In result they have found out, that excessive passion to watching various TV-programs, rigid diets, sedentary life and even relations with diffident people, reduce level of brain activity.

And rambling, going in for sports, classical literature and interesting work, on the contrary, stimulate work of the brain.

The British scientists have moved closer to creation of essentially new class of of asthma and allergy drugs. They have found a target for medicinal substances, influence on which will allow to prevent development of symptoms, informs The Journal of Immunology.

Scientists from Barts and The London School of Medicine and Dentistry carried out the researches in vitro and on mice.

Asthma and various kinds of allergies are met very frequently. Only in Great Britain more than 30 % of inhabitants have this or that variety of an allergy, and about five millions people suffer from asthma. The majority of drugs are directed on symptoms removal, in particular, an itch of eyes or coryza. There are also some epistatic immunity drugs; however these preparations increase susceptibility of an organism to infections.

The medicines blocking p110-delta molecule can stop development of allergic reaction before evident symptoms, and at the same time they do not suppress immunity. These drugs can be made as capsules or inhalers, and not just in injections.

Existing today drugs can’t destroy HIV completely in human organism. The killing virus hides from drugs in various reservoirs, major of which is lymphoid tissue of intestines, have determined the American scientists.

Experts from the American National institute of allergy and infectious diseases in Bethesda (Maryland) have conducted research with participation of eight HIV-positive patients. All participants have taken anti-retroviral drugs within two to ten years, felt well and had low virus load (low contents of a virus in blood).

Nevertheless, studying samples of lymphoid tissue of intestines, scientists have revealed presence of HIV. Researches have confirmed similarity of virus’ DNA found in intestines, with DNA of HIV from leukocytes. It proved that both tissues have constantly infected each other after replication of the virus.

In scientists’ opinion, maximum early beginning of HIV treatment is very important, as it will allow reducing the sizes of the virus tank at patients. Results of the research have been published in Journal of Infectious Diseases.

Grapefruit compound, which gives grapefruit bitterish taste, slows down extension of hepatitis C infection in an organism, have established American scientists. In their opinion, the combination of this substance with traditional viricides can relieve disease and prevent chronic form of the disease, informs magazine Hepatology.

According to the head of the research Raymond Chung and his colleagues from Massachusetts hospitals, the main role belongs to nagenginin. Their experiments have shown that action of this derivative substance reduces production of the virus from infected cells by 80 %. It is also important, that medical concentration of this substance is not toxic for an organism, has noted Chung.

According to the statistics, more than 3 % of the planet’s population is infected with hepatitis C, and in overwhelming majority of cases illness passes to the chronic form. The chronic hepatitis C infection can lead to cirrhosis and liver carcinoma.

Using of tattoo technique at vaccination can considerably increase efficiency of some vaccines, believe German scientists. On their data, vaccines injected into an organism by tattoo method, stimulate immune system much better, than usual vaccinations.

According to the researchers, vaccination with the help of tattooing leads to 16-fold increase in production of antibodies to papilloma virus. Such significant effect is connected to the big area of injection, and also with injuring influence of a needle and inflammatory reactions which additionally stimulate immune system, explain scientists.

The new method of tattoo-vaccination can increase efficiency of some DNA- vaccines which have appeared unable to cause required immune answer. However, because of duration and soreness of the procedure, they can hardly be used for preventive vaccination, especially at children.

World Health Organization has published the annual report which says, that the illnesses connected to smoking, take a life of one person every six seconds, killing on the average 5,4 million people a year.

Authors of the report inform that the number of tobacco epidemic victims exceeds death-roll of any infectious disease, therefore unless decisive measures, this figure by 2030 will grow up to eight millions deaths.

“And in 21st century from tobacco can die almost 1 billion people, who have not managed to overcome the weakness for cigarettes, snuffy, hookahs, cigars and tobacco-pipes”, - is said in the report.

WHA has informed that none of the country in the world has completely fulfilled requirements of the International tobacco control convention, which obliges participants to forbid advertising of tobacco products, rise in the price and taxes for their manufacture and sale and forbid smoking in public places for the sake of non-smokers.

Experts from stomatologic school Danedin in New Zealand have proved that often smoking marihuana three times increases risk of periodontitis.
In the research participated 900 young people, who were observed from 18 till 32 years. Scientists have also compared reports on drugs consumption by participants in the age of 18, 21, 26 and 32 years.

“Gum illnesses have been found at a quarter of people, who regularly used marihuana from 18 till 32 years - we have been struck with such significant increase in risk”, - declared head of the research Murray Thomson.

Periodontitis is a disease which leads to tooth destruction. 100 % of adult population of the Earth and 80 % of children have these or that signs of the disease, assert experts of the WHA.

It is necessary to note, that earlier American scientists came to a conclusion that CBD in marihuana structure, prevents cancer.

Local Turkey companies has created the short cigarettes for express - smoking.
The novelty, according to the creators, is faster to puff at and, accordingly, burns down faster, but enables smokers to receive needed for them nicotine doze.

The 7,2-centimetric cigarette, put on the market by Philip Morris, is developed for those people who because of the antitobacco law can not afford habitual long smoking breaks.

In 2006 Turkish authorities has banned smoking in public places.

It is necessary to note, that taking into account the new laws forbidding smoking in public places in some countries, the New Zealand scientists have created an electronic cigarette which allows the smoker to receive nicotine anywhere without pernicious consequences for an organism.
