Synthesis and characterization by experimental and theory research suitable on the CdS and CdO materials

In this paper, we have compared and analyzed experimental and theoretical research on A2B6 types semiconductor materials CdS and CdO. The XRD spectra of the samples were examined using an atomic force microscope and X-ray diffraction microscopy. During film deposition, the temperature of the crucible with a source (CdS) varied in the range Tsourse ≈ 800 ÷ 850°C, and the substrate temperature was maintained within the range Tp ≈ 250 ÷ 270°C. In this case, to ensure the reproducibility of the structures, a shutter was used, with the help of which the CdS deposition time was set, which ensured that the film thickness was the same from experiment to experiment

DIAGNOSTICS AND TREATMENT OF PERFORATED PYLORODUODENUM ULCERS IN WOMEN

The results of treatment of 75 women with perforated ulcers have been studied. There were prevailed women of middle and elderly age groups among patients who underwent surgery. A wound closure of perforated opening and abdominal sanation were performed by laparoscopic means in 30,7% of patients and using midline laparotomy in 29,3% cases. There were carried out the laparoscopic sanation of the abdominal cavity and the wound closure of perforated ulcer from mini-access using the set of mini-assistant in 10,7% patients. Radical operations were applied in 16% cases. The early postoperative complications took place in 8,1% of the patients, the rate of lethality was 4,0%. The long-term results were evaluated and considered as good in 55,5% women, satisfactory - in 30,1% and unsatisfactory - in 14,2% cases

REPARATION SYSTEM GENES: POPULATION DIFFERENCES IN HEREDITARY OVARIAN AND BREAST CANCER DETERMINED BY NEXT-GENERATION SEQUENCING

Introduction. Development of hereditary ovarian cancer (OC) and breast cancer (BC) is caused by genetic abnormalities in the DNA reparation system consisting of more than 100 genes. However, currently in the majority of medical centers in Russia, diagnosis of hereditary OC and BC consists of determination of the most frequent mutations (8 points) in the BRCA1 and BRCA2 genes using polymerase chain reaction (PCR). Moreover, these mutations are common in Slavic population while in other populations they are rare or altogether absent.The study objective is to perform a population analysis of mutations in the reparation system genes which must be considered during chemotherapy prescription.Materials and methods. Using next-generation sequencing (NGS), we analyzed reparation system genes in 139 blood samples of Tatar female patients with hereditary OC and BC. To compare mutation rates, 67 blood samples from Slavic female patients examined at the Federal Research Clinical Center FMBA (Moscow) in 2014-2016 were analyzed by real-time PCR.Results. Real-time PCR has shown a 5382insC (NM_007300.3:c.5329dup)  mutation in 36 % of Slavic patients. The same mutation was observed only in 7 % of Tatar women. Performed NGS analysis of 139 Tatar female patients with hereditary BC and OC has identified 61 mutations in the reparation system genes, one third of which (28 %) didn’t belong to the BRCA1/BRCA2 genes.Conclusion. The NGS method allowed to identify rare mutations characterizing different ethnic groups facilitating prescription of optimal chemotherapy
