Precision Nanocluster-Based Toroidal and Supertoroidal Frameworks Using Photocycloaddition-Assisted Dynamic Covalent Chemistry.

Atomically precise nanoclusters (NCs) have recently emerged as ideal building blocks for constructing self-assembled multifunctional superstructures. The existing structures are based on various non-covalent interactions of the ligands on the NC surface, resulting in inter-NC interactions. Despite recent demonstrations on light-induced reversible self-assembly, long-range reversible self-assembly based on dynamic covalent chemistry on the NC surface has yet to be investigated.

Implication of solvent polarities on browntop millet (Urochloa ramosa) phenolic antioxidants and their ability to protect oxidative DNA damage and inhibit α-amylase and α-glucosidase enzymes.

Phenolics of browntop millet extracted in solvents with varying polarities [water, methanol, acetone (80%), ethanol (70%)] were comparatively assessed for their phenolic profiles, antioxidant activities, DNA damage protection and enzyme inhibitory properties. Results indicated that acetone (80%) and ethanol (70%) were most effective in extracting millet phenolics than other solvents. Gallic, caffeic and ferulic acids were the major phenolic acids, myricetin and kaempferol were the most abundant flavonoids detected in all the extracts of browntop millet.

Citrus nutraceutical eriocitrin and its metabolites are partial agonists of peroxisome proliferator-activated receptor gamma (PPARγ): a molecular docking and molecular dynamics study.

Peroxisome proliferator-activated receptor gamma (PPARγ) agonists are potent insulin sensitizers in treating type 2 diabetes. Despite being very effective in the fight against diabetes-mediated complications, PPARγ agonists are accompanied by severe side effects leading to complicated health problems, making the discovery of novel safe ligands highly pertinent. A significant intense research effort is in progress to explore the PPARγ activating potential of a wide range of natural compounds.

Inhibitory effect of gallic acid from against α-glucosidase, α-amylase, aldose reductase and their interaction: Inhibition kinetics and molecular simulations.

In this exploration, we assessed the antihyperglycaemic properties of methanol extract of flowers of (MeT) against α-glucosidase, α-amylase and aldose reductase enzymes for the effective management of postprandial hyperglycemia. Hyperglycemia occurs when the body lacks enough insulin or is unable to correctly utilize it.

Maternal omega-3 LC-PUFA supplementation programs an improved bone mass in the offspring with a more pronounced effect in females than males at adulthood.

Early balanced nutrition is vital in achieving optimal skeletal mass and its maintenance. Although a lower omega-6 (n-6): omega-3 (n-3) long-chain polyunsaturated fatty acid (LC-PUFA) ratio is strongly linked with bone health, its maternal effect in the programming of the offspring's skeleton remains to be elucidated. Plugged C57BL/6 mice were fed either n-3 LC-PUFA Enriched Diet (LED) or a control diet (C) throughout their gestation and lactation.

Diindolylmethane Promotes Metabolic Crisis and Enhances the Efficacy of Centchroman in Breast Cancer: A H NMR-Based Approach.

Diindolylmethane (DIM) is a key metabolite of indole-3-carbinol found in cruciferous vegetables such as broccoli, cauliflower, and cabbage.

In this study, we have attempted to understand the cross-feeding and resource sharing between a generalist degrader and probiotic utilizers for utilizing dietary galactomannans. In mono-cultures, Bacteroides ovatus DSMZ 1896 grew maximally on substituted galactomannans and produced high amount of succinate.

Vanillic acid potentiates insulin secretion and prevents pancreatic β-cells cytotoxicity under HO-induced oxidative stress.

Background: Oxidative stress is known to impair cellular functions and, therefore, plays a significant role in the pathophysiology of various diseases, including diabetes. The persistently elevated glucose levels may cause enhanced mitochondrial reactive oxygen species generation, which in turn can damage the pancreatic β-cells. In this study, we have investigated the effect of vanillic acid on preventing HO-induced β-cells death and retaining its insulin secretion potentiating effect in the presence of HO.

Maternal Plasma Glycerophospholipids LC-PUFA Levels Have a Sex-Specific Association with the Offspring's Cord Plasma Glycerophospholipids-Fatty Acid Desaturation Indices at Birth.

Fatty acid desaturases, the enzymes responsible for the production of unsaturated fatty acids (FA) in fetal tissues, are known to be influenced by maternal-placental supply of nutrients and hormones for their function. We hypothesize that there could be a gender-specific regulation of unsaturated FA metabolism at birth, dependent on the maternal fatty acid levels. In this study, 153 mother-newborn pairs of uncomplicated and 'full-term' pregnancies were selected and the FA composition of plasma glycerophospholipids (GP) was quantified by gas chromatography.

Dietary Diindolylmethane Enhances the Therapeutic Effect of Centchroman in Breast Cancer by Inhibiting Neoangiogenesis.

Tumor angiogenesis is primarily regulated by vascular endothelial growth factor and its receptor (VEGF-VEGFR) communication, which is involved in cancer cell growth, progression, and metastasis. Diindolylmethane (DIM), a dietary bioactive from cruciferous vegetables, has been extensively studied in preclinical models for breast cancer prevention and treatment. Nevertheless, the possible role of DIM in the angiogenesis and metastasis regulations in triple-negative breast cancer (TNBC) remains elusive.

Hydrothermal treatment of hemp seeds (Cannabis sativa L.): impact on its dehulling yield, fatty acid profile and nutritional characteristics.
