27.06.2008Taking as a basis the fact that white blood cells – leukocytes – perform the function of fighting infections and thus prolong human life, scientists at the University of Palermo analyzed the relationship between life expectancy and the content of leukocytes in the blood.
27.06.2008Several substances have been identified that inhibit the binding of regulatory regions of DNA with the estrogen-receptor complex activating them. These compounds effectively blocked the production of proteins that stimulate the growth and proliferation of cancer cells expressing
27.06.2008The authors believe that this discovery expands the therapeutic possibilities of introducing normal tRNAs into defective mitochondria of patients in order to correct violations.
27.06.2008The results of the study open the way to the development of new classes of drugs for the treatment of Alzheimer's disease. The high selectivity of the action of such drugs is assumed, since, unlike the ApoE gene, the CALHM1 gene is active only in the brain.
26.06.2008The authors believe that, in general, genomic health is an inherited factor, and epigenetic changes observed during life explain the increasing predisposition to the development of various diseases with age.
26.06.2008The level of dehydroepiandrosterone sulfate – a precursor that the body converts into female and male sex hormones – in the blood of men is a strong prognostic factor of longevity.
26.06.2008Existing miRNA tracking tags glow for no more than a minute, while quantum dots emit light for many hours. Moreover, the new approach is 5-10 times less toxic to living cells than the chemical compounds currently used to monitor the course of RNA interference.
26.06.2008The ability to control a computer without the help of hands excites the minds of neurophysiologists all over the world, and several interfaces have already been created that connect a computer with different organs of the human body and directly with the brain. Scientists from the Research Institute of Physiology named after A.A.Ukhtomsky St. Petersburg State University suggest using eye movement for this purpose. The first experiments confirmed that this method works.
25.06.2008Many generations of parents tell their children about the need to eat vegetables, because "vegetables are the key to health." Recently, these persuasions were supported by the results of a study that demonstrated the benefits of vegetables, especially if you use them all your life.
25.06.2008A preliminary study of the drug "Stemamin" showed that its composition does not correspond to the formulation stated in the regulatory documentation. According to the expert opinion, this remedy does not contain living cells, since stem cells cannot live in any cosmetic forms.
25.06.2008With the introduction of insoluble, as well as soluble one- and three-molecular forms of beta-amyloid, no recorded effects were observed. However, the introduction of a two-molecular soluble beta-amyloid caused the development of symptoms characteristic of Alzheimer's disease in rats.
24.06.2008Harvard researchers have deciphered the mechanisms underlying the fact that the ROCK1 protein significantly suppresses inflammation of the vascular walls in atherosclerosis, which is the main cause of heart attacks and strokes. The authors found that ROCK1 is necessary for immune cells – macrophages – to clean the walls of blood vessels from fat deposits. A normal side effect of such cleansing is inflammation, but often this process gets out of control, which causes the opposite result - the growth of atherosclerotic plaques and blockage of arteries.
24.06.2008The exact model of the African catarrhal fever virus exceeds the size of the original by more than five million times. It will help veterinarians develop more effective drugs to combat the spread of infection.
24.06.2008On June 22, 2008, surgeon Fyodor Uglov died in St. Petersburg at the 104th year of his life. He got into the Guinness Book of Records as the world's oldest practicing surgeon.
24.06.2008A healthy lifestyle significantly changes the expression of hundreds of genes. The activity of a large number of genes, including several involved in the formation of tumors, decreases, while the work of other genes, including several involved in the fight against various diseases, is noticeably activated.
24.06.2008The changes occurring with the vessels during menopause are very complex and multifaceted, and the authors emphasize that the currently available knowledge is insufficient to determine the best method of hormone replacement therapy.
24.06.2008Compared with high testosterone levels, low levels of this hormone increase the risk of death (from any cause) by 2.5 times during the next 10 years of life.
24.06.2008Operatives of the Ministry of Internal Affairs of the Russian Federation are investigating a criminal case of fraud with the production and sale of the drug "Stemamine" in Russia, allegedly containing stem cells.
24.06.2008Using a set of techniques, the authors found three types of opiate receptors (delta, kappa and mu) and two types of cannabinoid receptors (CB1 and CB2) on the surface of human spermatozoa. Moreover, receptors of all types are found on the head, middle part and tail of spermatozoa.
