Calibration of Troitsk nu-mass detector readout electronics by signal digital filters
We present the results of tuning and calibration of the detector electronics
in the signal digitization mode. The goal of the experiment is to search for a
possible sterile neutrino signature in tritium beta-decay. The read-out
electronics work in direct oscilloscope mode, which requires to optimize time
frame the with the goal to minimize noise and energy resolution. We use a
7-pixel silicon drift detector (SDD) and a CMOS charge sensitive preamplifier
with very low integration capacitor. Amplifier forms a slowly rising output
shape and operates in pulse-reset mode. The 125 MHz ADC digitizes the signals.
Using calibration data from Fe55 and Am241 gamma sources we check triangular
and trapezoid digital filters to obtain the best noise and energy resolution
performance. We are also examining the option to differentiate the output
signal.Comment: 9 pages, 8 figure
LAPAROSCOPIC SURGERY IN TREATMENT OF ENDOMETRIAL CANCER (RESULTS OF 7-YEAR CLINICAL EXPERIENCE AT THE N.N. PETROV NATIONAL MEDICAL RESEARCH ONCOLOGY CENTER)
Introduction. The main method of treatment of endometrial cancer, the most common oncological disease, is surgery. Introduction of high-tech operations into gynecological practice promoted active use of laparoscopy in treatment of malignant tumors of the endometrium.Objective. To evaluate effectiveness of video endoscopic surgery in treatment of endometrial cancer.Materials and methods. In the period from 2010 to 2016, 1127 patients with endometrial cancer underwent surgery using video endoscopic complex with high resolution cameras at the N.N. Petrov National Medical Research Oncology Center, Ministry of Health of Russia.Results.Β Using video endoscopic technology, excision of the uterus with appendages was performed in 588 (52.3 %) patients, excision of the uterus with appendages and pelvic lymph node dissection was performed in 523 (46.4 %) patients including 16 (1.4 %) patients with serous and papillary serous forms of endometrial cancer who also underwent omentectomy. No intraoperative complications were observed. In the majority of patients, postoperative period was characterized by early activization, satisfactory intestinal peristalsis on day 1, minimal complications, absence of contraindications for adjuvant beam therapy.Conclusion. Video endoscopic technology is a modern method of surgical treatment allowing to perform the full scope of planned radical surgical intervention in patients with endometrial cancer irrespectively of age and concomitant disorders with minimal traumatization, risk of intraand postoperative complications as well as favorable and fast rehabilitation period

Background. Hereditary genetic mutations are a significant risk factor for malignant transformation of cells and cancer development. Hereditary genetic mutations account for 15 to 25 % of all ovarian carcinomas. Purpose of the study: to summarize data on hereditary ovarian malignancies, namely: genetic defects, features of the clinical course, treatment options, and disease prevention. Material and methods. A systemic search was undertaken using PubMed, Medline, Cochrane Library databases for publications from 1999 to 2021. Results. The review describes the main genetic defects and hereditary cancer syndromes predisposing to the development of hereditary malignant ovarian tumors. The features of the clinical course and response to drug therapy have been presented. This article summarizes clinical guidelines of the professional communities (National Comprehensive Cancer Network (NCCN), American Society Of Clinical Oncology (ASCO), The U.S. Preventive Services Task Force, and European Society For Medical Oncology (ESMO). These guidelines contain early detection strategies and approaches to prevent the development of cancers in mutation carriers. Conclusion. Detection of hereditary cancer syndromes is important for patients and their families. Recognizing hereditary predisposition to cancer is important to allow timely surveillance and preventative interventions for both patients and family members.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.

Β Β The literature review is devoted to the peculiarities of artificial lung ventilation (ALV) in patients with morbid obesity during laparoscopic oncosurgical interventions in the Trendelenburg position. At present, there are no consensus recommendations on the choice of the optimal ALV mode during anesthesia in this area of oncosurgery. When analyzing data obtained from other types of operations, there was no impression that there were significant advantages of any ALV modes, both with volume and pressure control. However, high values of positive end-expiratory pressure (PEEP) have the most evidence of benefit in this category of patients, and the inversion of the duration of the respiratory cycle phases without creating a high PEEP can help reduce the risk of lung damage when all other ALV techniques do not allow for adequate oxygenation.Β Β ΠΠ±Π·ΠΎΡ Π»ΠΈΡΠ΅ΡΠ°ΡΡΡΡ ΠΏΠΎΡΠ²ΡΡΠ΅Π½ ΠΎΡΠΎΠ±Π΅Π½Π½ΠΎΡΡΡΠΌ ΠΏΡΠΎΠ²Π΅Π΄Π΅Π½ΠΈΡ ΠΈΡΠΊΡΡΡΡΠ²Π΅Π½Π½ΠΎΠΉ Π²Π΅Π½ΡΠΈΠ»ΡΡΠΈΠΈ Π»Π΅Π³ΠΊΠΈΡ
