Stem cells against heart attack: another success

According 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.

The tolerance of immunosuppressors is determined by genes

A 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.

Genetic opposites attract

In 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.

Artificial leather will soon come off the assembly line

According to the developers, there are about two years left before the launch of automated production of artificial skin consisting of living cells. The estimated capacity of the production line is 5,000 units of leather per month, and the cost of one sample is less than 34 euros, which significantly exceeds existing offers.

Prolonging life and a low-calorie diet: another connecting link

The protein, which plays a key role in tumor formation, oxygen metabolism and inflammation, is involved in signaling pathways that regulate life expectancy while reducing the caloric content of the diet. New data on the relationship between a low-calorie diet and longevity may allow the development of drugs that help maintain health for many years.

One type of stem cell is good, and two are better

The tendency to form tumors is a serious problem on the way to the use of embryonic stem cells for the treatment of a variety of diseases and injuries. Malignancy of embryonic stem cells can be avoided if bone marrow stem cells are transplanted at the same time.

Treating a heart attack in advance: prenatal cell therapy

The adult body's own stem cells are not enough to restore the myocardium after a heart attack. Cell therapy has been successfully used to prevent and eliminate damage to the heart muscle after a heart attack, but has not yet been used as a preventive measure, and not just before a heart attack, but even before the birth of a potential patient.

The RNA World: the first step

A group of scientists from the University of Manchester (England) managed to synthesize a ribonucleotide (a compound necessary for the formation of RNA) in external conditions comparable to the conditions of the primitive Earth, and on the basis of molecules that were most likely in the primary broth.

Gene patents are illegal!

According to the plaintiffs, patents for research on various genes restrict the civil liberties of patients, allow patent-holders to set an inflated cost of genetic tests, and also deprive other organizations of the opportunity to study these genes.

The heart helps to restore blood vessels

In response to damage to the vessel wall, smooth muscle cells move from a state of "resting phenotype", in which they are only able to contract, to a state of "synthesis phenotype", when they begin to proliferate. The FHL2 protein synthesized by heart cells suppresses the activity of genes necessary for the preservation of smooth muscle cells of blood vessels in a state of "rest".

Cancer diagnosis and treatment: "4-in-1" nanoparticles

The researchers connected fluorescent dye, RNA fragments and peptide fragments to iron oxide nanoparticles. The task of peptides is to identify tumor cells, RNA fragments suppress the work of a number of genes characteristic of cancer cells, killing them. Magnetic iron oxide nanoparticles play the role of contrast for MRI, and fluorescent dye allows you to observe cancer cells using microscopy.
