The risk of developing diabetes type two in women depends on the size of her breasts in the younger years, say Canadian researchers. According to their data, women with large breasts often fall ill from diabetes, said Canadian Medical Association Journal.

In a study conducted by scientists from the University of Toronto, was included about 92 thousand women. Member, whose average age was 38 years old, interviewed on the size of their breasts in twenty years. Since then, scientists monitored the women, locking the newly diagnosed cases of diabetes.

Comparing data obtained, the researchers found that women with larger Bras A rarer all cases of diabetes. Women with a magnificent breast size Bras B cases of diabetes by 32% more likely to size S - 71% more often and with a size D - 58% more likely than women to the size of Bras A. These figures were obtained after taking into account known factors the risk of diabetes, particularly heredity and excessive body mass.

Diabetes mellitus type II associated with reduced sensitivity of cells to insulin, and usually develops in people over 40 years. Only in Britain live 1.8 million people suffering from diabetes mellitus type II.

The reason the relationship between big breasts and diabetes type II is not precisely known. Scientists suggest that the primary role of fatty breast tissue, which may increase the surplus of resistance cells to insulin.

«Smart» pills

Everyone who visited the country in different time zones, is well known, as may adversely affect the time difference at-being. But the problem was resolved specialists from the Russian Institute of Ecology and Evolution.

They created a synthetic analogue of melatonin - sleep hormone, produced by the body naturally. The drug is a small pill - one pill that is sufficient to flight after the long-range body adapted to the unusual conditions of the distant edges for just one night. Depending on the part of the world, which holds its way people, the drug dose is changed. For example, if you fly to the capital of France, the 0.1 mg immediately field twelve nights - and everything you promised normal sleep. If the destination is the eastern countries, such as India, the dose doubled - 0.2 mg before you lie down to sleep. Now tourists an opportunity not only to admire the local scenery, but also empty.

Testosterone is not associated with risk of prostate cancer

The natural level of testosterone in the blood does not affect the risk of prostate cancer (prostate), although both considered before. This information should encourage scientists to look for new ways to the problem of prostate cancer.

More than two dozen clinical studies focused on the link between testosterone levels and risk of prostate cancer. However, the results of the studies were not allowed to make a final conclusion.

Epidemiologist Andrew Roddam (Oxford University, UK) and his colleagues analyzed data collected by the world. Scientists interested in the level of testosterone in men, sick or not sick with cancer of the prostate (3 886 and 6 438 men, respectively). Prostate cancer usually strikes older men. The disease is the second as a cause of cancer death among men (at first - lung cancer).

“We compared the level of testosterone in men, ill with prostate cancer later, and those who are not sick. It turned out that between hormone levels and the risk of the disease there is no connection”, - said Andrew Roddam. Testosterone - is the main male hormone responsible for the development of muscle mass, fat distribution, bone mass, sexual desire and potency. In the women’s body testosterone too, but its level is much lower.

The role of testosterone in the maintenance of male health cause controversy. Testosterone promotes the growth of prostate cancer, so researchers believed that hormone levels affect the risk of the disease. Some types of prostate cancer by blocking action of testosterone.
In the past year been able to prove that men with higher testosterone less likely to die from heart attacks, strokes and other causes. A study conducted by British epidemiologists, should spur scientists to find new risk factors.

“The data obtained oblige the scientific community to abandon an attractive and convenient conjecture, and seriously study these modified risk factors” - a new study commented Paul Godley (University of North Carolina, USA).

Psychologists from the University of Berkeley and the University of Florida have proposed a new theory to explain why people love movies that exploit negative emotions - such as horror films. Until now until the end unclear why many viewers spend money to have their threatened.

Formerly known were the two most popular explanations popularity horror movies. The first states that during the viewing audience actually do not be afraid, but merely experiencing a pleasant sense of stimulation. Other - fear that the two hours needed to ensure that at the end of the film, regardless of what ends described therein history, the viewer experienced euphoria, far from terrible nightmares and the spectacle of sounds.

The authors of the new theory believe that both versions are incorrect. In their view, people love to watch horror movies happy because feel unfortunate. They just like the frightening, the most terrible moments of the film brought him the greatest pleasure. According to researchers, people who love uzhastiki, psychologically different from those who dislike such films. Article about this magazine will be published Journal of Consumer Research.

The first literary works in the genre of horror is considered a novel written by a British aristocrat Horasom Volpolom in 1764 - “The Castle of Otranto.” As in 1818, Mary Shelley published the story “Frankenstein”, became classics of the genre.

Probably the first horror movie considered the German “Golem”, shot director Paul Wegener in 1915. The first film such a direction, acquired wide popularity was also a German “The Cabinet of Dr. Caligari”, released on screens in 1920. In 1922 in Germany was withdrawn first film about the Vampire - “Nosferatu”. In 1931, in the U.S. were lifted first films about Dracula and Frankenstein.

Since then, industry production horrors produced many works of this kind, says Washington ProFile. Many researchers say that horror films were often not simply “pugalkami” - they reflect the underlying fears of their contemporaries before the war, famine, secret societies, criminals, epidemics, aliens, etc.

The popular American writer Stephen King in the book “Dans-Makabr” where he outlines his views on the horror genre, wrote: “If the movies - it dreams of mass culture, the horror movies - her nightmares.

When you enjoy ice cream on a hot day, you have a sense of coolness there. But experts argue that ice cream is unable to truly change the body temperature.

In the heat body temperature depends on the amount of fluid in the body. If you drink is not enough liquid, hard to maintain normal body temperature. Ice cream melts in the mouth and also turns into a liquid. To really cool, experts advise not only is ice cream, but also drink enough fluid.

According to “Health News Digest”.

Korean scientists reported receiving muscle cells from human nerve cells by means of artificially synthesized small molecules. These nerve cells can be used to treat diseases such as stroke, Alzheimer’s and Parkinson’s.

In numerous experiments showed that damaged or dead nerve cells can be replaced imposed from outside. But one of the main obstacles to the introduction of cell therapy into clinical practice - no reliable source of donor nerve cells.

Korean scientists from Seoul Yonsei University used synthetic “small molecule” neyrodazin (neurodazine) - substance, a member of the many drugs - to get nerve cells from easily accessible and rapidly reproducing immature muscle cells - mioblastov.

The work was done on the culture of mouse cells. A week after adding in culture Wednesday neyrodazina 40-50% mioblastov turned into cells, on the structure and functions similar to the nerve cells and neurons expressing specific proteins. Additional studies have shown that similar changes under the influence of the substance occur in a culture of human skeletal muscle cells. This is the first work, which with the help of a chemical nerve cells derived from neplyuripotentnyh mioblastov and mature human myocytes.
