Extracting information on virus-human interactions and on antiviral compounds based on automated analysis of large text collections.

The development of effective antivirals is of great importance due to the threat associated with the rapid spread of viral infections. The accumulation of data in scientific publications and in databases of biologically active compounds provides an opportunity to extract specific information about interactions between chemicals and their viral and host targets. This information can be used for elucidation of knowledge about potential antiviral activity of chemical compounds, their side effects and toxicities.

Repositioning of drugs for the treatment of major depressive disorder based on prediction of drug-induced gene expression changes.

Major depressive disorder (MDD) is one of the most common diseases affecting millions of people worldwide. The use of existing antidepressants in many cases does not allow achieving stable remission, probably due to insufficient understanding of pathological mechanisms. This indicates the need for the development of more effective drugs based on in-depth understanding of MDD's pathophysiology.

[Primary chronic osteomyelitis of the mandible in children: etiology and diagnostics].

Primary chronic osteomyelitis (PCO) is a rare non-bacterial autoinflammatory severe disease that most often affects children aged 7 to 12 years and is much less common in adults. The most common areas of lesion are long tubular bones, however, any bones of the skeleton, including the lower jaw, can be affected. The clinical picture of this disease is complex and similar to many tumor and tumor-like bone lesions, which often leads to a significant delay in making a correct diagnosis.

Features of internal absorbed dose microdistribution in biological tissue irradiated by 31SiO2 microparticles compared with dose microdistribution from exposure to 56MnO2 particles.

Radiobiological studies are ongoing to understand the consequences of internal exposure to neutron-activated radioactive microparticles, which were sprayed over experimental rats and mice. Special attention in these experiments is given to internal irradiation with radioactive microparticles with short-lived neutron-activated radionuclides 31Si (T1/2 = 2.62 h) and 56Mn (T1/2 = 2.

Proteomic Analysis Identifies Multiple Mechanisms of 5-Fluorouracil-Induced Gut Mucositis in Mice.

Damage of the gastrointestinal mucosa is a major side effect of the anticancer drug 5-fluorouracil (5-FU). Insight into the molecular pathogenesis of 5-FU-induced gut mucositis is expected to justify the strategies of prophylaxis. We analyzed intestinal specimens obtained from Balb/c mice treated with 70 mg/kg 5-FU daily for up to 6 days.
