A heart attack without scarring on the heart?
If we can simulate in mammalian heart cells the process that is observed in danio rerio, we will understand why we have not yet observed the regeneration of the heart in humans.

25.03.2010Traditionally, age-related ailments have significantly "rejuvenated". However, there is also good news: if you are examined in time, you can detect serious diseases at the earliest stage and be cured.
25.03.2010The branch of the evolutionary tree on which a possible new species of hominins is located separated from the branch leading to us about a million years ago – long before the paths of modern man and Neanderthal diverged.
25.03.2010A new approach to the study of age–related memory changes – the study of the brain of people who have retained a good memory until old age - will make it possible to establish what exactly allows such people to avoid senile senility.
25.03.2010Botox and skin tightening are not enough to rejuvenate the face at all, since the metamorphoses that occur with aging are due to significant changes in the shape of the facial bones, especially the lower jaw.
25.03.2010Pleiotropin, a natural cell growth factor, stimulates the proliferation of hematopoietic stem cells not only in culture, but also in the conditions of the body.
24.03.2010Microglia – immune cells of the nervous system – destroys neurons in the brains of mice suffering from Alzheimer's disease, under the influence of signaling proteins synthesized by the neurons themselves. It remains only to learn how to block these signals.
24.03.2010On March 30, the Institute of Modern Development will host the presentation of the National Scientific Report "All about Cholesterol", which combines the whole range of information, research, statistics, analytics, problems and practical recommendations related to cholesterol.
24.03.2010Entrepreneurs aged from 16 to 30 can become participants of the Young Entrepreneur of Russia – 2010 contest.
24.03.2010During the first clinical studies using a complex of nanoparticles and small interfering RNAs, researchers were able to successfully block the expression of the target gene in cancer cells.
23.03.2010A new direction of synthetic biology is the creation of fully "customizable" proteins. The ribosome, which reads not three, but four nucleotides at a time, allows the use of more than 250 non-natural amino acids for the design of biopolymers.
23.03.2010The St. Petersburg Association of Disabled People, Veterans and Blockade Workers implements on a voluntary basis a social project of free computer literacy training for elderly people "Grandma-Online", "Grandpa-OnLine".
23.03.2010Nanochips that do not disrupt the work of the cell can serve as sensors that transmit information about what is happening in the cytoplasm, which means they can provide a huge service to scientific research and medicine.
23.03.2010Cell culture grows much better in a three-dimensional matrix than on a flat surface of a Petri dish. But instead of using a porous gel, magnetic nanoparticles can be introduced into cells and suspended in the thickness of the nutrient medium using a magnet.
22.03.2010However, there are probably very few foreign cells in our body – according to estimates, about one in a million. Therefore, researchers have come up with a special name for the phenomenon – microchimerism.
22.03.2010To create new airways, a donor trachea was used, purified to a collagen base, on which stem cells obtained from the bone marrow of a small patient were applied.
22.03.2010New sequencing technologies make it possible to study more deeply the effect of genetic changes on cellular processes and predisposition to diseases.
22.03.2010In some cases, it makes no sense to change proven, effectively working systems for the synthesis of biological products with the help of bacteria and yeast. However, the extreme profitability of algae compared to mammalian cell lines is obvious.
22.03.2010Scientists have developed a new, extremely effective method for studying the processes of competition between spermatozoa that have entered the female body – they observe what is happening live.
22.03.2010Non-coding sections of DNA control the activity of genes and play an equally important role in determining such individual characteristics as a person's appearance, his development and even predisposition to certain diseases.
