Picophytoplankton distribution along Khatanga Bay-shelf-continental slope environment gradients in the western Laptev Sea.

The spatial variations of photosynthetic picoplankton abundance and biomass and the picoplankton's contribution to chlorophyll concentration along the transect from Khatanga Bay to the continental slope in the western part of the Laptev Sea were studied in September 2017. Picoeukaryotes dominated in the picophytoplankton communities. Picophytoplankton in Khatanga Bay showed more variability than those over the Laptev shelf and continental slope: abundance and biomass were the highest in the southern part of the bay and markedly decreased with increasing salinity in its northern part.

[Evaluation of the long-term results of the surgical treatment in patient with vaginal aplasia in the presence of functioning uterus].

Results of surgical treatment of 28 adolescent girls with vaginal aplasia and functioning uterus are analyzed. The uterus had to be removed in all the patients 1.5 to 6 months after abdominal colpopoiesis with preservation of functioning uterus; after sigmoidal colpopoiesis the uterus was preserved in 85% of patients.

[Dopplerometry in the 2nd trimester of pregnancy].

Ultrasonic device Toshiba 140 A/G was used to examine 118 women at pregnancy terms 10 to 30 weeks. Umbilical artery, intraplacental arteries, and retroplacental blood flow were assessed. All the women were divided into two groups by the results of retrospective analysis of dopplerograms.

[Surgical treatment of patients with destructive pulmonary tuberculosis and liver pathology].

The results of surgical treatment of 102 patients with destructive tuberculosis of the lungs and liver pathology are presented. It was shown possible to widen the operability ranges in the patients by using the up-to-date treatment including hemosorption and laser technique. After hemosorption there was a significant improvement of liver function.

[Characteristics of the use of radiation from various types of lasers in the surgical treatment of patients with pleural empyema].

The article analyses experience in the use of beams of various types of lasers in treatment of 152 patients with different forms of pyothorax of tuberculous and nontuberculous origin. Semiconductor and carbon dioxide laser devices were used in the stages of surgical treatment. Methods for the use of lasers in the pre- and postoperative periods and during the operation are described.
