Distribution and anthropometric characteristics of Rotterdam criteria-based phenotypic forms of Polycystic ovaries syndrome in Ukraine.

Objective: To explore the distribution of Rotterdam-based PCOS phenotypes and their associations with anthropometric parameters predictive of cardiometabolic risks in Ukrainian referral PCOS women.

Study Design: It was a cross-sectional study conducted by the Ukrainian Society of Gynecological Endocrinology between September 2021 and January 2022 involving 42 clinics in 10 regional centres representing the major geographical parts of Ukraine. Two hundred obstetrician-gynecologists whose practice facilities corresponded to study criteria were committed to entering records of their PCOS patients aged 20-45 years into the uniform data collection forms.

Millimeter-wave interferometry and far-forward scattering for density fluctuation measurements on LTX-.

The ≈ 1 mm ( = 288 GHz) interferometer for the Lithium Tokamak Experiment- (LTX-) will use a chirped-frequency source and a centerstack-mounted retro-reflector mirror to provide electron line density measurements along a single radial chord at the midplane. The interferometer is unique in the use of a single source (narrow-band chirped-frequency interferometry) and a single beam splitter for separating and recombining the probe and reference beams. The current work provides a documentation of the interferometry hardware and evaluates the capabilities of the system as a far-forward collective scattering diagnostic.

Magnetic perturbation diagnostics in the high-temperature lithiated environment of LTX-.

Magnetic perturbation measurements will be invaluable for characterizing Lithium Tokamak Experiment Beta (LTX-) plasmas due to the time-evolving 3D nature of the magnetic fields generated by eddy currents in the vessel and copper shell segments, as well as enhanced MHD instability drive due to newly introduced neutral beam heating. The LTX- upgrade includes two new arrays of Mirnov coils: a shell eddy sensor array of two-axis coils distributed over the back surface of one shell segment and a toroidal array of poloidal field coils at the low-field side midplane gap. Evaporative lithium wall-coating and the high temperatures required for liquid lithium wall operation both complicate the implementation of in-vessel diagnostics.

A frequency-modulated continuous-wave reflectometer for the Lithium Tokamak Experiment.

The frequency-modulated continuous-wave reflectometer on LTX (Lithium Tokamak Experiment) and the data analysis methods used for determining electron density profiles are described. The diagnostic uses a frequency range of 13.1-33.

AGE AND SEX CHARACTERISTICS OF MELATONIN-POSITIVE-LABELED CELLS OF THE GASTRIC MUCOSA IN DESYNCHRONOSIS IN RATS.

The aim of the research was to study the state of melatonin-positive-labeled cells (MPLC) of GM in desynchronosis in rats of different age and gender. 780 sections of the pyloric part of the gastric mucosa were studied in rats of both genders at the age of 9, 15 and 20 months. Animals were divided into intact control groups and the groups of the animals kept under the conditions of continuous light for 14 days - desynchronosis.
