Ginkgo biloba improves memory in older people, the researchers reported. In addition, the researchers found a high risk for a stroke or micro-stroke in people who use ginkgo. The reasons are unclear and need to be confirmed in other studies. Ginkgo biloba - one of the most commonly used additives. As a result, some studies, scientists have found that improving the herb in the memory, as a result of others who help themselves affect mental function of people with dementia. Scientists conducted a three-year study of 118 people over 85 years, the. No problems with memory Half of them had to take a dietary supplement Ginkgo biloba, and the other half of the participants - placebo. The results showed that the difference in the incidence of dementia and memory impairment in those Ginkgo did not was significant, compared with those who took a placebo. However, when the researchers considered how closely people followed the instructions to take pills, they found that those who took ginkgo regularly reduces the risk of memory problems by 68% compared to those taking placebo. According to the scientists to elucidate the facts are interesting because ginkgo biloba is widely used and is an inexpensive supplement. More research is needed, how useful and welcome ginkgo with certainty.

Found the gene responsible for hair loss
German scientists have found a gene that is responsible for one of the various types of hair loss. The work of scientists in the journal Nature Genetics. At the Institute of Human Genetics, scientists examined the hereditary forms of hair loss. This disease occurs in both men and women, as the researchers it hypotrichosis simplex. In this disease, the intensive hair loss occurs in childhood. In the study, researchers found that the cause for the disease encoded a mutation in a gene, which is a specific receptor on the surface of cells of the hair follicle. Hypotrichosis simplex - is a rare inherited defect, but the investigation into the causes of the disease contribute to the understanding of the fundamental mechanisms of hair loss. Further confirmation of the importance of this gene for hair growth is the work of scientists from Columbia University. Researchers led by Angela Christiano (Angela Christiano) found that a mutation in the gene for the G-beloksopryazhenny receptor results in the syndrome of woolly hair. In this disease also affects the normal growth of hair.
The age-related macular degeneration affects the risk of heart attack
Age-related macular degeneration (AMD) - the leading cause of blindness have been linked to an increased risk of heart attacks associated. The researchers found that the risk of death from cardiovascular disease at least doubled in people with the disease from AMD. Scientists suggest that the cause may be a drug for the treatment of the disease, as they affect the operation of the ships. VMD - a disease with genetic predisposition and the primary localization of the pathological process at the level of the pigment epithelium and capillary macula (central) part of the retina. According to the results of epidemiological studies, the age-related macular degeneration is the leading cause of blindness and visual impairment in older adults. Sydney group of researchers conducted a study in which 3,600 people participated, who were about the age of 49 years at baseline. Of these 2,335 people were re-interviewed after 5 years, and in 1952 after 10 years. Scientists have found that people who have AMD in the early beginning of the study, had twice the risk of dying from a heart attack in the next 10 years. Those who have had late-stage disease, the risk of heart attack by 5-fold. Experts believe that to find out more precise relationship between the need for further research, as scientists have long ceased to find the exact cause of the GMR and the relationship of cardiovascular disease.
