The Baksan Experiment on Sterile Transitions (BEST) was designed to investigate the deficit of electron neutrinos ν_{e} observed in previous gallium-based radiochemical measurements with high-intensity neutrino sources, commonly referred to as the "gallium anomaly," which could be interpreted as evidence for oscillations between ν_{e} and sterile neutrino (ν_{s}) states. A 3.414-MCi ^{51}Cr ν_{e} source was placed at the center of two nested Ga volumes and measurements were made of the production of ^{71}Ge through the charged current reaction, ^{71}Ga(ν_{e},e^{-})^{71}Ge, at two average distances.

Material And Methods: Routine clinical examinations, sputum seeding, enzyme immunoassay were made in 214 patients admitted to therapeutic departments of two large Barnaul hospitals.
Results: Mp CAP was diagnosed in 21.
The degree of structural and functional heart changes was evaluated by means of Doppler echocardiography in 120 patients with chronic obstructive pulmonary disease (COPD) of different degrees of severity. Conventional immunological laboratory techniques were used in all the patients to evaluate the condition of cell-mediated, humoral, and cytokine-mediated immunity; inflammatory process activity and the degree of endotoxicosis were evaluated by measuring blood levels of acute phase proteins and medium mass molecules. The study showed that the character of heart remodeling depended on COPD severity.

Material And Methods: 5212 inpatients of the pulmonary department were examined from 1994 to 2000.
Results: NRI was found in 41 of 912 patients with BA (4.
