Are you afraid of obesity? Check your dopamine receptors!
Obese people may have fewer dopamine receptors, and they overeat to compensate for the lack of pleasure from food.

17.10.2008Professor Lisa Schwartz, one of the authors of the study, believes that the public is often presented with special, "frightening" statistics on certain diseases that do not take into account certain indicators.
17.10.2008The researchers injected progenitor cells of T-lymphocytes from the bone marrow of donors to pig embryos. The immature immune system of embryos did not perceive human cells as foreign, so they could multiply freely in their body.
17.10.2008A Council on biotechnology has been established under the Government of the Kirov Region.
15.10.2008A study of the brain tissue of epilepsy patients operated on at the Spanish Cajal Institute showed that neurons in men contact each other more often than in women.
13.10.2008Carriers of unfavorable gene variants located on chromosome 20, as well as on the X chromosome, have a seven-fold risk of developing baldness before the age of 50.
13.10.2008Experts say that investments in the development of new technologies will pay off just by the time the crisis ends.
13.10.2008Instead of a viral vector, scientists used plasmids to inject "embryonic" genes into fibroblasts, with the help of which they managed to successfully transform ordinary skin cells into pluripotent stem cells.
13.10.2008A single intravenous injection of the hormone erythropoietin (EPO) immediately after inarct can minimize the process of apoptosis and thereby limit damage to cardiac tissues.
10.10.2008At least six variants of the Serping 1 gene mutation have been found; most of them are associated with age-related macular degeneration.
10.10.2008The 2008 Nobel Prize in Chemistry was awarded to three scientists working in the USA for the discovery of green fluorescent protein (GFP) and the development of methods for its application in science.
08.10.2008The new diagnostic method is based on determining the number of fragments of fetal chromosomes in the mother's blood. In addition to Down syndrome, researchers were able to accurately identify cases of trisomy of the 18th chromosome (Edwards syndrome) and trisomy of the 13th chromosome (Patau syndrome).
08.10.2008Excessive intake of calories into the body, even if it does not lead to an increase in body weight, disrupts the work of the hypothalamus, which plays a major role in maintaining energy balance.
07.10.2008An American company promises to decode the human genome for five thousand dollars next year.
07.10.2008One of the tested populations, whose cells express the CD24 cell surface marker, formed fat deposits in experimental animals. This population usually makes up no more than 0.08% of all non-fat cells contained in normal adipose tissue.
07.10.2008"Useless" bacteria inhabiting the intestinal mucosa help the body to protect itself from infections.
07.10.2008The winners of the award were Harold zur Hausen for the discovery of the human papillomavirus association with cervical cancer and Francoise Barre-Sinussi and Luc Montagnier for the discovery of the human immunodeficiency virus.
06.10.2008Inactivation of a pair of genes involved in fat burning increases energy consumption and prevents the development of diet-induced obesity.
06.10.2008Resembling a hairnet, the "magic hat" uses magnetic impulses to change the nature of the work of certain parts of the brain. With its help, the volunteers demonstrated outstanding results when testing various abilities.
06.10.2008The authors plan to "train" bacteria to recognize chemical processes associated with danger in the body. Such a "live indicator" can be configured so that the synthesis of a signal protein begins in response to the appearance in the body of molecules characteristic of the undesirable effects of drugs or indicating the presence of malignant tumors.
