[[Peculiarities of transcutaneous nephrolithotripsy in the patient's position lying on the back].].

In 2014 - 2016 yrs transcutaneous nephrolithotripsy was performed in 245 patients for nephrolithiasis, of them in 228 (93.1%) - in position of patient lying on the abdomen (1st group), in 17 (6.9%) - lying on the back (2nd group) because of various concur- rent cardio-vascular and respiratory diseases present.

[DRAINLESS TRANSCUTANEOUS NEPHROLITHOTRIPSY. OUR FIRST EXPERIENCE].

Experience of performance of a drainless transcutaneous nephrolitotripsy (DTN) for renal concrements was summarized. In 245 patients mini—DTN was done, оperation was finished with the nephrostomic drain installation — in 224 (91.4%), and without such procedure — in 21 (8.

[Assimilation of carbon dioxide and oxidation of methane in various zones of the Rainbow hyperthermophilic field zones].

Rates of carbon dioxide assimilation and methane oxidation were determined in various zones of the Rainbow Hydrothermal Field (36 degrees N) of the Mid-Atlantic Ridge. In the plume above the hydrothermal field, anomalously high methane content was recorded; the microbial population density (up to 10(5) cells/ml) was an order of magnitude higher than the background values; and the CO2 assimilation rate varied from 0.01 to 1.
