03.06.2009For the first time, Dr. Lei Xiao and the team of the laboratory of the Shanghai Institute of Biochemistry and Cell Biology, which he directs, managed to obtain "artificial" pig stem cells. As in the case of induced pluripotent human stem cells, pig tissue cells pass into an undifferentiated state under the influence of certain proteins.
03.06.2009In accordance with the current legislation, pharmacies are intended for the sale of medicines. Perfumery and cosmetic products do not belong to medicines. Whether their sale in pharmacies is misleading customers is a separate question.

02.06.2009Usually, follicular lymphoma can be suppressed with chemotherapy, but after a year, relapses are characteristic of this type of cancer. Patients who received an immunostimulator and a foreign protein with their own marker lived without relapses for 44 months. This is a very significant achievement, since previously with follicular lymphoma it was not possible to increase either the duration of the relapse-free period or the survival rate.
01.06.2009According to the researchers, the counter can be associated with any external events, the influence of which the bacterium is able to feel (for example, it regularly reacts to the presence of certain toxins), as well as with changes in the internal state of the microorganism. The bacterium can be forced to "self-destruct" after the completion of a certain number of cell divisions or after a given time.
01.06.2009Researchers from the University of New South Wales (Australia) have learned how to grow stem cells on contact lenses. This method of therapy will improve the vision of people suffering from corneal damage.
01.06.2009A new Canadian study highlights the general health issues of older people and the factors that ensure a healthy old age and active longevity.
29.05.2009The drug, which is commonly used in the treatment of diabetes, protects neurons in multiple sclerosis.
29.05.2009In the future, such corkscrew and sperm hybrids can deliver drugs to various tissues and organs of patients. They will be able to swim through blood vessels, they do not need internal energy sources to move, and there are no moving parts in the design of "nanopropellers", which makes them more reliable.
29.05.2009The priority sectors for investing funds are those that will develop most dynamically after the end of the economic crisis and bring the highest possible return on invested capital. Among such industries, the experts of the Alfa-Capital Management Company identified information technologies, biotechnologies, energy and nanotechnology.
28.05.2009Lung stem cells that activate when damaged may be the cause of cancer.
28.05.2009According to the authors, the positive effect of stem cells in the treatment of the consequences of myocardial infarction can be explained by the fact that they promote the regeneration of heart muscle cells, as well as stimulate the formation of new blood vessels.
27.05.2009The increased risk of periodontal disease and coronary heart disease is due to a certain section of the antisense DNA chain on the ninth chromosome.
27.05.2009The Sox21 gene is involved in the formation of stem cells that form the outer layer of the hair shaft, and disruption of its work may be one of the causes of baldness.
26.05.2009A simple genetic test will help determine the degree of tolerability of immunosuppressive therapy in patients with transplanted kidneys. The test allows you to determine the individual dose of drugs for each patient, minimizing side effects.
26.05.2009In people forming married couples, the number of differences in the family of genes of the main histocompatibility complex significantly exceeds the average indicators. Perhaps this is one of the evolutionary mechanisms that prevents cases of incest and regulates the immune system.
