Exploring the link between environmental chemical exposures and epigenetic modifications in diabetes mellitus.
( The Association of Basic Medical Sciences , 2025 , Article Review)Diabetes mellitus (DM) is a globally prevalent metabolic disorder characterized by impaired glucose homeostasis and insulin secretion. Beyond traditional risk factors like lifestyle and genetics, environmental pollutants, ... -
Comprehensive analysis of human coronavirus antibody responses in ICU and non-ICU COVID-19 patients reveals IgG3 against SARS-CoV-2 spike protein as a key biomarker of disease severity
( Microbiology Society , 2025 , Article)Introduction. Pre-existing immunity to human coronaviruses (HCoVs) may shape the immune response in COVID-19 patients. Increasing evidence suggests that immune cross-reactivity between SARS-CoV-2 and other coronaviruses ... -
Antibody-dependent enhancement of SARS-CoV-2, the impact of variants and vaccination
( Taylor and Francis Group , 2025 , Article)This study characterized antibody-dependent enhancement (ADE) in serum samples from individuals exposed to SARS-CoV-2 via infection or vaccination and evaluated its association with SARS-CoV-2 variants (Wuhan and Omicron), ... -
The impact of pre-existing immunity on the emergence of within-host immune-escape mutations in Omicron lineages
( Microbiology Society , 2025 , Article)The Omicron variant of SARS-CoV-2 circulating amongst highly immunized populations is anticipated to induce immunological pressures, potentially compromising existing immunity. This study investigates vaccine-induced ... -
Glucosamine Schiff bases as fluorescent sensors for recognition of Al+3 and Zn+2 ions
( Elsevier , 2025 , Article)Glucosamine salicylidene (GAS) and Glucosamine-4-nitrosalicylidene (GANS) were synthesized using microwave and investigated as water-soluble chemosensors for aluminum and zinc ions. UV–vis, fluorescence titration, binding ... -
Medicinal Phytocompounds as Potential Inhibitors of p300-HIF1? Interaction: A Structure-Based Screening and Molecular Dynamics Simulation Study
( Multidisciplinary Digital Publishing Institute (MDPI) , 2025 , Article)Background: Hypoxia plays a key role in cancer progression, mainly by stabilizing and activating hypoxia-inducible factor-1 (HIF-1). For HIF-1 to function under low oxygen conditions, it must interact with the transcriptional ... -
Protection conferred by SARS-CoV-2 infection across a spectrum of reinfection symptoms and severities
( BMJ Publishing Group , 2025 , Article)Background SARS-CoV-2 infection is associated with protection against reinfection. This study analysed this protection across different reinfection symptoms and severities, comparing the preomicron and omicron eras. Methods ... -
N-Lactoyl amino acids as metabolic biomarkers differentiating low and high exercise response
( Institute of Sport , 2025 , Article)Aerobic physical exercise has significant benefits for cardiovascular health; however, some individuals experience no benefit or even adverse effects. One reason for poor tolerance to aerobic exercise may be a low percentage ... -
