Aim: Oxidative stress, caused by postprandial activities, is a major global health issue causing chronic diseases like diabetes mellitus, cancer, and asthma. Therefore, it was envisaged to design and synthesize a series of substituted 4-hydroxypyridine-2(1 h)-ones in order to develop new molecules that can reduce oxidative stress and modulate α-amylase activity also.

Materials & Methods: An environmentally benign, solvent and catalyst free, natural product inspired synthesis of 4-hydroxypyridin-2(1 h)-one derivatives has been developed.

Biologically produced silver nanoparticles are becoming a more appealing option than chemically produced antioxidants and antimicrobial agents, because they are safer, easier to manufacture and have medicinal properties at lower concentrations. In this work, we employed the aqueous pomegranate peel extract (PPE) to synthesize silver nanoparticles (PPE-AgNPs), as peel extract is a rich source of phytochemicals which functions as reducing agent for the synthesis of PPE-AgNPs. Additionally, the PPE was examined quantitatively for total phenolics and total flavonoids content.

The present study investigated the urinary metabolic profiles of early pregnant and non-pregnant Mithun to identify potential pregnancy detection biomarkers. Urine samples were collected on days 0, 10, 18, 35 and 45 of gestation from pregnant (n = 6) and on days 0, 10 and 18 from non-pregnant (n = 6) Mithun. Urinary metabolites were assessed using proton nuclear magnetic resonance (H NMR) spectroscopy and identified 270 metabolites.

Root-knot nematodes pose a serious threat to crops by affecting production and quality. Over a period of time, substantial work has been done toward the development of effective and environmentally benign nematicidal compounds. However, due to the inefficiencies of previously reported synthetics in achieving the target of safe, selective, and effective treatment, it is necessary to develop new efficacious and safer nematicidal agents considering human health and environment on top priority.

Purpose: Retinoblastoma (RB) is the most common intraocular tumor in pediatric age group. The role of genetics has been explored in predicting survival prognosis, but its role in predicting globe salvage remains largely unexplored. We hereby aim to isolate cell-free DNA (cfDNA) from aqueous humor (AH) in RB eyes and validate its use for genetic studies.

Plastics, while providing modern conveniences, have become an inescapable source of global concern due to their role in environmental pollution. Particularly, the focus on bisphenol A (BPA) reveals its biohazardous nature and association with liver issues, specifically steatosis. However, research indicates that BPA is just one facet of the problem, as other bisphenol analogues, microplastics, nanoplastics and additional plastic derivatives also pose potential risks.

The current study identified two new climate-resilient groundnut-based cropping systems (GBCSs), ., groundnut-fenugreek cropping system (GFCS) and groundnut-marigold cropping system (GMCS), with appropriate system-mode bio-compost embedded nutrient management schedules (SBINMSs) for semi-arid South Asia. This 5-year field study revealed that the GMCS along with leaf compost (LC) + 50% recommended dose of fertilizers (RDF) in wet-season crop (groundnut) and 100% RDF (RDF) in winter-season crop (marigold) exhibited the highest system productivity (5.

The integrated stress response (ISR) enables cells to survive a variety of acute stresses, but chronic activation of the ISR underlies age-related diseases. ISR signaling downregulates translation and activates expression of stress-responsive factors that promote return to homeostasis and is initiated by inhibition of the decameric guanine nucleotide exchange factor eIF2B. Conformational and assembly transitions regulate eIF2B activity, but the allosteric mechanisms controlling these dynamic transitions and mediating the therapeutic effects of the small-molecule ISR inhibitor ISRIB are unknown.

A widespread strategy employed by pathogens to establish infection is to inhibit host-cell protein synthesis. Legionella pneumophila, an intracellular bacterial pathogen and the causative organism of Legionnaires' disease, secretes a subset of protein effectors into host cells that inhibit translation elongation. Mechanistic insights into how the bacterium targets translation elongation remain poorly defined.

Micronutrient malnutrition and suboptimal yields pose significant challenges in rainfed cropping systems worldwide. To address these issues, the implementation of climate-smart management strategies such as conservation agriculture (CA) and system intensification of millet cropping systems is crucial. In this study, we investigated the effects of different system intensification options, residue management, and contrasting tillage practices on pearl millet yield stability, biofortification, and the fatty acid profile of the pearl millet.

Pearlmillet-chickpea cropping system (PCCS) is emerging as an important sequence in semi-arid regions of south-Asia owing to less water-requirement. However, chickpea (dry-season crop) faces comparatively acute soil moisture-deficit over pearlmillet (wet-season crop), limiting overall sustainability of PCCS. Hence, moisture-management (specifically in chickpea) and system intensification is highly essential for sustaining the PCCS in holistic manner.

Purpose: This study sought to investigate the association of molecular markers with chronic ocular sequelae in Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN).

Methods: One hundred SJS/TEN patients (200 eyes) with confirmed diagnosis were enrolled between July 2011 and July 2015 from a tertiary eye-care hospital, and their clinical histories were noted. Each eye was scored for severity of manifestation on a scale of 0-5.

Silver nanoparticles (AgNPs) were fabricated using L. leaf extract, belonging to the variety HM 425, as leaf extracts are a rich source of phytochemicals such as polyphenols, flavonoids, and sugars, which function as reducing, stabilizing, and capping agents in the reduction of silver ions to AgNPs. These phytochemicals were quantitatively determined in leaf extracts, and then, their ability to mediate AgNP biosynthesis was assessed.

Article Synopsis
  • Aqueous leaf extract from the HM 444 variety was used to synthesize silver nanoparticles (AgNPs), characterized using various techniques including UV-Visible spectroscopy and electron microscopy.
  • The AgNPs produced were 21 nm in size, spherical, and effective for degrading synthetic dyes like Methylene blue, Methyl orange, and Rhodamine B.
  • The nanoparticles showed high sensitivity as solid bio-based sensors for detecting heavy metal ions (Hg and Fe), suggesting the leaf extract is a cost-effective and eco-friendly method for nanoparticle fabrication.
