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.
05.06.2008In females "sitting" on a starvation diet, aging of the body leads to significant violations of the functions of the ovaries, and in starving males, age-related changes in the cells of the testes are much less pronounced.
05.06.2008Preliminary studies on a small group of mice did not reveal the toxicity of single-walled carbon nanotubes.
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.
04.06.2008The main areas of research: impaired tissue regeneration in injuries, cardiovascular diseases, blood diseases, chronic limb ischemia and diabetes mellitus.
04.06.2008Experiments on human cell lines have demonstrated the ability of artificial viruses to efficiently transport miRNA into cells and selectively block gene expression.
04.06.2008The possibility of sequencing an individual genome does not mean that people should immediately run for genetic testing in the hope of significantly improving their health.
03.06.2008Prenatal screening studies, which are used to detect chromosomal abnormalities in the fetus, reveal no more than half of such anomalies. At the same time, these studies are associated with an increased risk of miscarriage and infant mortality.
03.06.2008Artificial organelles, if filled with a suitable set of enzymes, can also work in other human cells – and this opens up opportunities for a new type of anti-cancer therapy.
03.06.2008Blocking the activity of TFR-beta stimulates the movement of peripheral macrophages through the blood-brain barrier, which surround neurons and eliminate amyloid plaques in the brain.
03.06.2008The program called Fracture Putty ("Putty for fractures") involves the creation of a biodegradable material that, when applied to the fracture area, will be able to restore the bearing properties of the bone in a few days.
03.06.2008Currently, researchers are conducting the first phase of clinical trials of vaccination against type 1 diabetes using the first technique, with the isolation of dendritic cells using leukapheresis.
03.06.2008In another experiment to create prosthetics controlled by the "power of thought", monkeys with electrodes implanted in the brain learned to eat with the help of a mechanical hand. In the future, such devices will be able to make life easier for people – paralyzed or amputated.
03.06.2008Gold nanoparticles covered with alternating bands of hydrophobic and hydrophilic synthetic molecules, which mimics the ordered structure of proteins, penetrated through the membrane without harming the cell.
