Antiviral Potential of Extracts (Prepared by Repercolation) Against Influenza A (H1N1) Virus.

An antiviral effect of extracts prepared from aerial parts of nine species and from leaves of two species of the genus L. was investigated for potential antiviral activity toward influenza A (H1N1) virus. The toxicity of dry extracts was analyzed, and the most selective extract was identified in vitro.

CLINICAL PROFILES AND CHARACTERISTICS OF MENSTRUAL DYSFUNCTION IN WOMEN AFTER SUFFERING FROM COVID-19 OR VACCINATION.

Objective: The aim: To investigate changes in the characteristics of menstrual function in women after suffering from Covid-19 or vaccination against SARS-CoV-2.

Patients And Methods: Materials and methods: After the retrospective analysis of 378 medical records patients were divided into: Group 1 (177 women) with menstrual function disorders (MFD) after COVID-19, Group 2 (121 women) with MFD after SARS-CoV-2 vaccination, Group C (80 women) without MFD after COVID-19 or vaccination (controls). The study focused on the clinical and hormonal menstrual cycle characteristics and factors influencing MFD.

Robust fully controlled nanometer liquid layers for high resolution liquid-cell electron microscopy.

Liquid cell electron microscopy (LCEM) has long suffered from irreproducibility and its inability to confer high-quality images over a wide field of view. LCEM demands the encapsulation of the sample between two ultrathin membranes (windows). In the vacuum environment of the electron microscope, the windows bulge, drastically reducing the achievable resolution and the usable viewing region.

Thidiazuron and LED Lighting Enhance Taxifolin and Rutin Production in Turcz. Microshoot Culture.

Turcz., distributed throughout the northern region of East Asia has been considered to be an alternative natural source of taxifolin (dihydroquercetin) and rutin. The present study was conducted based on a biotechnological approach to develop an environment friendly and efficient system to produce taxifolin and rutin microshoots, using different thidiazuron (TDZ) treatments (0.

Optimization of Biomass Accumulation and Production of Phenolic Compounds in Callus Cultures of L. Using Design of Experiments.

L. is a valuable medicinal plant with adaptogenic, neuroprotective, antitumor, cardioprotective, and antidepressant effects. In this study, design of experiments methodology was employed to analyze and optimize the interacting effects of mineral compounds (concentration of NO and the ratio of NH to K) and two plant growth regulators [total 6-benzylaminopurine (BAP) and α-naphthylacetic acid (NAA) concentration and the ratio of BAP to NAA] on the growth and the production of total phenolic compounds (TPCs) in calluses.
