AI Article Synopsis

  • Vigna aconitifolia sprouts (Moth bean sprouts) showed significant nutritional and antioxidant benefits after six days of sprouting, with increases in fresh weight (7.0 times), soluble proteins (2.4 times), carbohydrates (3.0 times), and minerals (5.5 times).
  • The phenolic content of the sprouts rose by 28%, with caffeic, ferulic, cinnamic acids, and kaempferol being the main compounds identified.
  • After metal ion supplementation, MBS exhibited enhanced metal uptake and further improved phenolic levels, along with a reduction in oxidative stress in HepG2 cells.

Article Abstract

Vigna aconitifolia sprouts (Moth bean sprouts, MBS) were analyzed for their nutritional and antioxidant properties during sprouting. Sprouting for six days led to a 7.0 fold increase in fresh weight, 2.4 fold increase in soluble proteins, 3.0 fold increase in carbohydrates, and a 5.5 fold increase in mineral content. Phenolic content also increased by 28% during germination. Caffeic acid, ferulic acid, cinnamic acid and kaempferol were the predominant phenolic compounds detected in the ethanolic extracts of MBS by HPLC. Following supplementation with metal ions (200 μg ml⁻¹), the sprouts demonstrated a considerable increase in metal ion uptake, with improved phenolic content. MBS ethanolic extracts also reduced intracellular oxidative stress in HepG2 cells.

Background: Lamotrigine clearance can change drastically in pregnant women with epilepsy (PWWE) making it difficult to assess the need for dosing adjustments. Our objective was to characterize lamotrigine pharmacokinetics in PWWE during pregnancy and postpartum along with a control group of nonpregnant women with epilepsy (NPWWE).

Methods: The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study was a prospective, observational, 20 site, cohort study conducted in the United States (December 2012 and February 2016).

Cellulases are an ensemble of enzymes that hydrolyze cellulose chains into fermentable glucose and hence are widely used in bioethanol production. The last enzyme of the cellulose degradation pathway, β-glucosidase, is inhibited by its product, glucose. The product inhibition by glucose hinders cellulose hydrolysis limiting the saccharification during bioethanol production.

This study aimed at quantifying the potential effects of plant and soil microbial interaction on selenium (Se) volatilization, with the specific objectives of identifying soil bacteria associated with rabbitfoot grass () and demonstrating the enhancement of Se volatilization in the soil-Indian mustard () system through inoculation of the soil with the identified best Se-volatilizing bacterial strain. Soil bacteria were isolated from topsoil and rhizosphere soils of rabbitfoot grass, and the bacterial colonies were characterized via PCR-DGGE and DGGE band analysis prior to their identification using 16S rDNA sequencing technique. produced over 500-fold more volatile Se in a culture medium treated with 15 µg Se/mL (equal mixture of SeO , SeO and selenomethionine) than any of the other eight identified bacterial strains.

Oblique plane microcopy (OPM), a variant of light-sheet fluorescence microscopy (LSFM), enables rapid volumetric imaging without mechanically scanning the sample or an objective. In an OPM, the sample space is mapped to a distortion free image space via remote focusing, and the oblique light-sheet plane is mapped via a tilted tertiary imaging system onto a camera. As a result, the 3D point-spread function and optical transfer function are tilted to the optical axis of the tertiary imaging system.

Lipid nanoparticles (LNP) are the most clinically advanced non-viral gene delivery system. While progress has been made for enhancing delivery, cell specific targeting remains a challenge. Targeting moieties such as antibodies can be chemically-conjugated to LNPs however, this approach is complex and has challenges for scaling up.
