The empty intestine secretes ghrelin, which is released into the blood and enters the hypothalamus. There ghrelin activates CaMKK2, which leads to an increase in the formation of neuropeptide Y, which directly stimulates appetite.

Prenatal diagnosis: blood test instead of invasive procedures

Advances in the development of new non-invasive tests for prenatal diagnosis indicate that in the near future, genetic defects of the fetus can be detected using a blood test.

Oncology techniques

Cancer stem cells, vegetable fats and prostate cancer, early diagnosis of lung cancer by oral epithelium... In oncology, something new and promising is being discovered every day.

Diagnosis of diseases by saliva: details and comments

Every day, the technologies of laboratory and functional diagnostics are supplemented with new techniques that allow you to quickly detect diseases at an early stage. Perhaps, in the future, people will be tested not for blood, but saliva.

Vaccination saves lives

Scientists were faced with the task of creating an effective vaccine against the human papillomavirus, and therefore against cervical cancer. And they were created: Gardasil quadrivalent vaccine and GlaxoSmithKline bivalent candidate vaccine.

Therapeutic antitumor vaccines are a matter of the near future

There are still many difficulties to overcome before therapeutic antitumor vaccines appear on the market, the most difficult of which is proving their effectiveness.

Ahead of the whole planet

Russia will become the first country in the world to sell a cancer vaccine. A small pharmacological company Antigenics announced on Tuesday that Russian regulatory authorities have approved Oncophage for sale.

Pot by prescription

Surprisingly, more than half of the psychoactive substances contained in marijuana can be used for medical purposes.

Cancer starved to death

A hunger strike may allow you to increase the dose of the drug, and thereby the effect on tumor cells without increasing the effect of toxic effects on the body.

The search for an AIDS vaccine has reached a dead end

Cancer doesn't have enough red wine

Scientists used resveratrol in a fairly high concentration - about 50 g per liter of nutrient fluid in which pancreatic cancer cells grew. In the wine obtained as a result of natural fermentation, the concentration of this substance reaches 30 g per liter.

Personalized medicine

In the medical community, personalized medicine is considered either as a fundamentally new approach to medical practice, or as a continuation of the traditional principle of "treating not the disease, but the patient."

Is it possible to defeat AIDS with the help of immunosuppression?

With the spread of HIV resistance to antiretroviral drugs, immunosuppressive therapy may be the only tool in the fight against AIDS.

Nuclear Metastasis switch

Scientists were able to stop the spread of breast cancer metastases and even return cancer cells to their original appearance by "turning off" the gene of one of the nuclear proteins.

Rapidly changing oncology

Modern drugs for the treatment of oncological diseases have fundamental differences from those that appeared on the market in the 1970s.

Cosmetics and genetics: what do they have in common?

Cosmetics that would be able to "intelligently" influence the genetic mechanisms of skin cells are still as far from real embodiment as gene therapy of diseases.

Hereditary diseases: it is possible to identify now, to cure – not yet soon

Until 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.

Immunochromatography: express diagnostics in the family doctor's bag

Immunochromatographic 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.

Commendation of Personalized Medicine (1)

By using molecular genetic analysis to achieve optimal medical results in the fight against a disease or a patient's predisposition to a particular disease, personalized medicine can lead to the introduction of new health standards.
