Nitrogen Fixation Activity and Genome Analysis of a Moderately Haloalkaliphilic Anoxygenic Phototrophic Bacterium .

The genome of the moderately haloalkaliphilic diazotrophic anoxygenic phototrophic bacterium A-36s isolated from an alkaline lake was analyzed and compared to the genomes of the closest species A-20s and DSM 11289. The genomic features of three organisms are quite similar, reflecting their ecological and physiological role of facultative photoheterotrophs. Nevertheless, the nitrogenase activity of the pure cultures of the studied bacteria differed significantly: the highest rate (4066 nmoles CH/mg of dry weight per hour) was demonstrated by while the rates in and were an order of magnitude lower (278 and 523 nmoles CH/mg of dry weight per hour, respectively).

[Ten-year risk of osteoporotic fractures in patients with chronic obstructive pulmonary disease estimated by FRAX method].

The study included 104 long-smoking men with COPD. The 10-year risk of osteoporotic fractures was estimated using the FRAX software. It was shown that patients with grade 2 COPD were at minimal risk of fractures of forearm, arm and vertebrae while those with COPD-4 were at maximum risk.

[Bone mineral density in patients with chronic obstructive pulmonary disease].

Aim: To study of bone mineral density (BMD) in patients with chronic obstructive pulmonary disease (COPD).

Subjects And Methods: 104 patients with COPD were examined. A study group comprised men with a long smoking history.

[Clinical and morphological features of gallbladder cholesterosis in children].

Although that the first reports of cholesterosis gall bladder were in the second half of the XIX century, there is still insufficient information about the frequency of its detection in children. According to some researchers, this disease was detected in patients aged 13 to 14 years. In other periods of childhood gallbladder cholesterosis is considered to be casuistic rarity.

[Diagnostic algorithm of biliary tract diseases in children].

Biliary tract (BT) diseases occupy one of the first places among the gastrointestinal diseases in children. The term "biliary tract" includes the gallbladder and intra-and extrahepatic bile ducts. The structure of biliary tract diseases had a significant increase in metabolic and inflammatory diseases, functional disorders.
