Molecular Angular Momentum Orientation Using Dressed States Created by Laser Radiation.

We have produced state selective molecular angular momentum orientation using dressed states created by a cw optical field. The experiment was carried out with Li_{2} molecules and a combination of left- and right-hand circularly polarized lasers. Our approach exploits the dependence of the Rabi frequency on the quantum number M, which makes it possible to achieve complete M-state selectivity and thus molecular angular momentum orientation relative to laboratory frame space-fixed axes.

Selenium nanoparticles enhance metabolic and nutritional profile in Phaseolus vulgaris: comparative metabolomic and pathway analysis with selenium selenate.

Selenium is a beneficial element in agriculture, particularly for its potential to improve plant growth and stress tolerance at suitable concentrations. In this study, Phaseolus vulgaris was foliar-sprayed with selenium selenate (Se) or selenium nanoparticles (SeNP) at different concentrations during the vegetative stage; afterward, the seed yield was analyzed for metabolomics using H, J-resolved and HSQC NMR data, and NMR databases. A total of 47 metabolites were identified with sugars being the major chemical class.

Integrative multi-omics analysis of autism spectrum disorder reveals unique microbial macromolecules interactions.

Introduction: Gut microbiota alterations have been implicated in Autism Spectrum Disorder (ASD), yet the mechanisms linking these changes to ASD pathophysiology remain unclear.

Objectives: This study utilized a multi-omics approach to uncover mechanisms linking gut microbiota to ASD by examining microbial diversity, bacterial metaproteins, associated metabolic pathways and host proteome.

Methods: The gut microbiota of 30 children with severe ASD and 30 healthy controls was analyzed.

Role of ivermectin and colchicine in the treatment of COVID-19: a randomized controlled clinical trial.

Introduction: The objective of this study was to assess the effectiveness of ivermectin and colchicine as treatment options for coronavirus disease 2019 (COVID-19).

Methodology: A three-arm randomized controlled clinical trial was conducted in the Triage Clinic of the family medicine department at Ain Shams University Hospitals on participants who had been diagnosed with moderate COVID-19. Patients aged < 18 years or > 65 years, with any co-morbidities, pregnant or lactating females, and those with mild or severe COVID-19 confirmed cases were excluded.
