Caffeine contributes to a harmonious shape

The study lasted 30 days and it was attended by 99 women. All of them twice a day, rub cream from 7% by the content of caffeine. At the beginning and end of the study measured the level of women’s thighs. A 80% participating thigh circumference decreased.

While it is not clear whether caffeine can fight cellulite. Using a special device, showing the level of blood flow in adipose tissue, scientists have tried to assess the impact on cellulite cream. It turned out that even in cases where the thigh circumference decreased in adipose tissue no significant changes. Scientists suggest that thirty days is not enough to affect cellulite.

«Cream with caffeine is not able to rid of cellulite, but it will look like harmonious. Whatever the case, the best method - it exercises », - is the principal author of the study Omar Lupi (Federal University of Rio de Janeiro).

The world’s first patient died of tuberculosis 500 thousand years ago

Half a million years ago, people already sick with tuberculosis. Symptoms of the infection have been discovered by scientists in the study of the remains of a young man living in Turkey, said American Journal of Physical Anthropology.

Previously it was thought that tuberculosis has appeared several millennia ago - the data were based on research on tissues of Egyptian and Peruvian mummies.

John Kappelman from Texas A & M University, who headed an international team of experts from the United States, Turkey and Germany, examined the skull of young men. The remains belonged to a man who, according to experts, refers to the first human beings migrated from Africa - Representatives of the type «people bipedal» (Homo Erectus).

Scientists found small (1-2 mm) defects in the bones of the skull, the shape and location of which showed that while men suffered tuberculosis - inflammation of soft and web cerebral shells. To do this, the disease caused by mycobacterium tuberculosis, education characterized by the so-called tuberculosis knobs, signs of which can be found in a study of the skull.

The researchers suggested that the deceased man was susceptible to infection because of declining immunity due to shortage of vitamin D. In their view, Homo Erectus, migrated north from tropical latitudes, suffered from the shortage due to lack of sunlight. The dark color of their skin, protects from sunlight, researchers believe.

TB - infection caused by Mycobacterium tuberculosos. The disease is transmitted by airborne droplets and can infect the lungs, bones, skin and other organs.

Sedentary lifestyles affect the psyche

Lack of physical activity threatens not only the man weighing redundant, but mental disorders ranging from depression to serious diseases. That is the conclusion reached British scientists, reported the BBC.

According to their data so far in Britain, only 35% of men and only 24% of women supported their physical activity at the level recommended by experts.

Professor Nanette Mutrie, an expert in sports physiology from the University of the Scottish city Stratklayd, noted that people only recently began to notice a link between sedentary lifestyles and mental disorders. “And now we have very strong evidence that physical activity can prevent depression”, - said N. Matray.

According to studies, people with low double the chance of falling into depression compared with those who have a lot of moves. In addition, there are reliable data, indicating that exercise - a good cure for depression, said the professor.

Researchers from the University of the English city of Bristol found that physical activity reduces the risk of a third development of Alzheimer’s. Scientists still can not explain such a significant effect, however, suggest that it may be due to improvements in the functioning of the cardiovascular system, as well as changes in chemical processes in the brain.

The Director-General of the British organization of nutrition professor Battriss Judy (Judy Buttriss) noted that in recent years, authorities have focused on the promotion of healthy eating. But “now need to find ways to help people become physically active, that they can protect their health and quality of life for old age” - she said.

Recommended Ministry of Health British rule of physical activity for adults is 30 minutes a day five times a week. According to the agency, the recommendation is not fulfilled most of the adult population. The alarming trend among children, who increasingly prefer low-class sport. Now the Ministry of Health established a norm of physical activity does not comply with 30% of boys and 40% of girls.

Doctors, manual therapy practitioners have long known that the withdrawal of pain and immobility neck muscles through massage can reduce blood pressure, but the reasons for this effect were not clear.

The team of scientists from the University of Leeds, UK (University of Leeds) showed how the state of the neck muscles affects blood pressure, pulse and respiration. Field of the brain where signals end of the neck, was identified more than 100 years ago, although it remained unclear functions. Now researchers have found a link between this area and cell nucleus tractus solitarius (single path) - area of the brain, which controls the autonomous functions of the organism. Scientists assume that signals from the neck can play a key role in ensuring the normal blood supply, which is regulated by the brain under a change in posture. If such signals are violated, people may lose his balance and blood pressure may go beyond the norm. The findings offer scientists a clear rationale for the effectiveness of manual therapy.

Scientists from the Medical Center Beth Israel Deaconess plot revealed the brain responsible for raising body temperature. Selective blocking of the centre, located in the hypothalamus, could become the basis for creating ANTIPYRETIC drugs, reported the journal Nature Neuroscience.

Previously, scientists knew that the inflammation is accompanied by evolving a biologically active substance - prostaglandin E2. This connection affects the hypothalamus - The Division of the brain responsible for the vegetative regulation of body temperature, appetite, water balance, sexual activity, vascular tone, etc.

Clifford Saper and his colleagues target a specific plot hypothalamus, which is responsible for raising body temperature. The experiments conducted on mice, which alternately “turns off” genes encoding EP3-receptors to prostoglandin E2. These receptors exist in many brain cells, and are responsible not only for development of fever, but also for other symptoms, including weakness and loss of appetite, reported Saper.

According to a scientist, eventually they were able to detect brain size of a plot, “turning off” EP3-receptors which block the development fever. The area plays a key role in raising body temperature, it turned medial nucleus, which is located in the median area hypothalamus.

“We suspect that in the human brain, everything happens exactly the same”, - said Saper.

ANTIPYRETIC funds currently used (such as aspirin), affect all receptors in the body - because of this there is a significant number of side effects. New data allow begin to develop safer drugs that affect specific receptors, summarized the scientist.

As it turned out, the virus is transmitted during oral sex without any damage to the oral cavity: fault to the molecule, which enters into relationship with the virus.

So far, it was believed that oral transmission of HIV is possible only person who has severely damaged gums. But this explanation does not suit you all, especially since it is proved that saliva has a strong antiviral effect. HIV transmission if one drink a glass, there is one device or kissed. Therefore, people, and many animals instinctively zalizyvayut disinfect wounds to the base.

The new discovery provides an acceptable explanation for the first mode of HIV transmission. According to scientists from the National Institute of Health USA, on the surface of tonsils have receptor CXCR4, through which the virus is connected to infect cells and transmit their genetic material.

This molecule - one of the first tested in a new therapy for treating infections. The surface of gum, in turn, is covered with molecules of another type, the so-called keratin, gums thicken the wall and serve as a barrier. Results of the study published in the American Journal of Pathology.

This discovery has become for many experts occasion to recall that condom use should not only sex with penetration - vaginal or anal, and recommended a condom with oral sex.
