[Comparative analysis of the microbiological stability of modern polymers for the manufacture of removable prostheses].

Objective: The aim of the study is to study the degree of adhesion of reference strains of microorganisms to the surface of modern polymer materials for the manufacture of removable prostheses.

Materials And Methods: The primary and residual microbial adhesion of 4 types of polymers was studied: acrylic polymer (Villacryl H Plus), monomerless polymer (Vertex ThermoSens), photopolymers for additive manufacturing (Harz Labs Dental Denture Base, Harz Labs Dental Sand). , , , and were used as reference strains.

Diastolic deceleration area in the fetal MCA: a new Doppler parameter.

Doppler velocimetry has been widely used throughout the years as a valuable tool in the follow-up and prognosis of various pregnancy complications. Numerous Doppler indices have been introduced to qualitatively describe fetal blood flow. Currently, the Pulsatility index (PI) is the most widely used index for this purpose.

Myasthenia gravis and covid-19 in pregnancy: a review of the literature and case series report.

Objectives: The aim of our study was to investigate the interrelations of symptoms, clinical outcomes and treatment regimens in pregnant women, diagnosed with myasthenia gravis and superimposed COVID-19 infection.

Methods: We conducted an observational retrospective study between August, 2020 and July, 2021. Five patients with preexisting MG and superimposed COVID- infection were included in our study.

Spectral and Texture Properties of Hydrophobic Aerogel Powders Obtained from Room Temperature Drying.

Attenuated Total Reflectance Infrared (ATR-IR) spectroscopy and texture measurements based on nitrogen adsorption-desorption isotherms are combined to characterize silica aerogel granules with different degrees of hydrophobicity. The aerogels were prepared from tetraethoxysilane via a room temperature hydrolysis-gelation process, solvent exchange, hydrophobization, and drying at subcritical conditions. The dependencies between the texture properties, pore architectures, surface fractal dimensions, and degree of hydrophobicity of the samples are extracted from the ATR-IR spectra and the adsorption-desorption isotherms.
