10.06.2008Despite the fact that sugar and sweeteners initiate the same taste recognition mechanisms (people are not able to distinguish their solutions by taste), sugar activates the brain regions associated with the formation of a sense of pleasure more strongly.

09.06.2008There are more than 600 enzymes in the human body that use vitamins or minerals as cofactors. Each person has about 5 rare mutant variants of enzymes and, possibly, several other, more common variants, the functioning of which can be improved with the help of vitamins and trace elements.

06.06.2008The authors found that skin keratin serves as a barrier between Langerhans cells and HIV and prevents infection. As part of the study, they applied estriol cream, which has been the standard treatment for post-menopausal vaginal atrophy for more than 30 years, to the inner surface of the foreskin and assessed the level of keratinization of the region using contact smears.
06.06.2008To be fair, it should be noted that in recent years two more methods of optical microscopy have been developed, allowing to see even finer details in living cells.
06.06.2008The authors suggest that human analogues of the genes they identified that control fat metabolism, regardless of the diet, have similar functions in the human body.
06.06.2008Scientists at the Karolinska Institute found that alcohol consumption is associated with a reduced risk of developing rheumatoid arthritis and the more respondents indulged in red and white, the less the risk of "catching" this autoimmune inflammation of the joints became.
06.06.2008As a result of the selection of the optimal shape of the surface and the parameters of electrical stimulation, the rate of formation of cartilage tissue based on the new nanofilm was increased by more than three times.
06.06.2008The results obtained indicate the fallacy of the generally accepted opinion about the weak toxicity of marijuana or even about its complete harmlessness. Despite the fact that moderate use may not cause significant neurotoxic effects, active daily smoking of marijuana can be toxic to brain tissue.

05.06.2008"We consider the most important area of activity to be those studies that are directly aimed at humans. I mean fundamental medicine, the design of new drugs, the study of biology issues that are directly related to human health." In particular, according to Osipov, the search for an effective drug against cancer requires close attention of scientists.
