Individual genome sequencing: make no mistake!

The 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.

Benefits and harms of prenatal screening

Prenatal 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.

"Upgrade" at the cellular level

Artificial 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.

How to incite macrophages on amyloid plaques

Blocking 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.

Putty for bones

The 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.

Improved vaccine against type 1 diabetes

Currently, 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.

Monkeys were taught to mentally control a prosthetic arm

In 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.

Striped nanoparticles

Gold 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.

Cytomegalovirus vaccine helps in the treatment of glioblastoma

cytomegalovirus is registered in the blood and in the tumor tissue in more than 80% of patients with newly diagnosed glioblastoma. Duke University scientists have suggested that vaccinating patients against cytomegalovirus may help in the fight against the tumor.

Renaissance creates a fund for investments in the pharmaceutical industry

Renaissance Investment Management Management Company plans to open the first mutual fund on the Russian market, which will invest shareholders' funds in the medical services market and pharmaceuticals.

A conditionally pathogenic bacterium produces a cure for intestinal inflammation

A substance produced by one of the types of symbiotic bacteria in the human intestine can become a new medicine for inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease.

Diabetics, take care of your heart – drink cocoa!

The results obtained prove that the use of natural flavonoids is an important factor in the prevention of cardiovascular diseases in patients with type 2 diabetes.

Bones from stem cells: a new achievement

Until now, when conducting such experiments, researchers have used high concentrations of a hormone that stimulates bone growth, which was injected into a carrier or a frame covered with stem cells. The new approach makes it possible to significantly reduce the concentration of hormones used and bring it as close as possible to the natural one.

Hormone replacement therapy: pros and cons

The authors suggested that the association between hormone replacement therapy and an increased risk of developing cardiovascular diseases, as well as breast cancer, was based on incomplete results.

Insulin-like growth factor-1 increases life expectancy

Data processing has shown that the low activity of insulin-like growth factor-1 corresponds to a significantly higher mortality rate than the high activity of this hormone.

Fruits and vegetables prevent acidification of the internal environment of the body

The "Western" type of diet contributes to the fact that as the body ages, a small but slowly increasing metabolic acidosis develops – acidification of the internal environment.

The first female genome has been read

Geneticists at Leiden University have completed a DNA scan of the first woman and the first inhabitant of Europe, whose genome will be fully decoded by the end of the year.

Quitting smoking improves Relationships

Comparing the data from 1971 and 2003, scientists built computer models of social networks and marked smoking and non-smoking people with different icons on them, and found that people quit smoking in groups.

A new cure for obesity: satiety after the first spoonful

Lock HIV in a cage?

Biologists from the medical schools of Emory University (Georgia), Vanderbilt University and the Mayo Clinic have found that HIV particles are "locked" in cells by the CAML protein (calcium-modulating cyclophilin ligand).
