Stem cells come out by the hour
If mesenchymal stromal cells rarely go beyond the bones on their own, then the release of hematopoietic stem cells into the blood occurs regularly, we can say – strictly by the hour.

11.02.2008Two nucleotides are connected by a strong covalent bond, and with the third and the amino acid – by weak physico-chemical bonds. To strengthen this connection, we need another three – complementary. It will turn out to be a six, which will be supported by hydrogen bonds between complementary nucleotides.
11.02.2008microRNAs are involved in the processes of individual development of the body, including temporary control, death, proliferation and differentiation of cells, embryonic laying of organs.
08.02.2008I advise you to be wary of representatives of pseudoscience and mythologists who have flooded our scientific space. Stem cells have a huge potential for the treatment of many diseases, but we are still looking for optimal opportunities for their proper use.
08.02.2008Until recently, mainly monogenic diseases that occur when one gene is disrupted have been studied. But most hereditary diseases are associated with simultaneous disruption of several genes and certain environmental influences.
08.02.2008The information circulating in the media that scientists have received the Nobel Prize in Physiology and Medicine for discoveries in the field of stem cells is rekindling interest in mysterious cells, both among specialists and among ordinary people. Since there are already a lot of myths on the Internet and scientists dealing with this problem, there are also a certain number of charlatans who use the moment to earn money and fame.
08.02.2008There are about 650 million personal computers in the world, and most of them use only a small part of their power when working. At the same time, these untapped resources can be used for the benefit of all mankind. To this end, in 2004, the World Community Grid system was created – the largest global computing system for solving the most important humanitarian problems.
07.02.2008British scientists (C) have found that daily consumption of nitrates, which are part of beet juice, as well as green leafy vegetables, helps to reduce blood pressure. It would be nice to check the effect on the pressure of sausages, sausages and other conditionally-food products, in which nitrites are added to preserve the pink color.
07.02.2008To date, more than a hundred cases of death have been registered in France in young people who were given growth hormone in childhood. Today, 16 years after the first death, the families of the victims are demanding justice at the trial that began in Paris.
06.02.2008A group of French and Spanish scientists led by population geneticist Luis Quintana-Murzi has discovered new evidence in favor of continuing human evolution.
06.02.2008By the time the "draft" sequence of the human genome was published in 2001, the figure 35,000 was generally accepted, but now genetic catalogs include approximately 24,500 genes. A new bioinformatic study shows that the number of "real" genes is even smaller: about 20,500.
06.02.2008Mario Capecci has had a fantastic academic career. Today, the knockout method, of which Capecci was one of the fathers, is already a classic of molecular biology.
06.02.2008Is human reproductive cloning possible? At the Congress, this question received a clear answer: "Yes." It was also stressed that "such a step should be carried out by responsible countries and for the sake of noble goals."
05.02.2008Immunochromatographic express diagnostics is a new high-tech method that allows not only to accurately diagnose a large range of the most serious pathologies (myocardial infarction, dangerous infections, inflammatory processes, oncological diseases, hormonal disorders, etc.) outside of laboratory conditions in 5-20 minutes, but also to assess their severity.
04.02.2008The treatment of prostatitis, especially its severe and rare forms, is shrouded in a halo of mystery. Often the disease is associated with such difficulties that in life this diagnosis is carried as a heavy cross.
04.02.2008Wages are lower than in science only in such sectors as agriculture, non-productive services for the population, culture and art, education and forestry. Almost every 13th emigrant is a scientist! The main group of emigrants are programmers, biotechnologists, molecular geneticists.
04.02.2008In January 2008, the participants of the Molecular and Cellular Biology program found themselves in the information and budget vacuum zone – no one canceled the program, but also did not extend it, as, indeed, other programs of the Presidium of the Russian Academy of Sciences. Those scientists who believed the seriousness of the promises of the Academy of Sciences and returned to Russia, having received grants for 3 and 5 years, found themselves "in limbo."
31.01.2008The Russian Foundation for Basic Research and the Austrian Scientific Foundation announce the 2009 contest of joint Russian-Austrian research projects.
