Clindamycin-resistant among Staphylococcus aureus: Investigation into phenotypic and genotypic profiles
( Public Library of Science , 2025 , Article)Background Antimicrobial resistance (AMR), particularly methicillin-resistant Staphylococcus aureus (MRSA), is a pressing global health concern. These bacteria are increasingly becoming resistant to the most commonly ... -
Silver-based dressings for the prevention of surgical site infections: evidence from randomized trials
( Elsevier , 2025 , Article)BackgroundSurgical site infections (SSIs) are a major cause of postoperative complications, increasing morbidity and healthcare costs. Silver-based dressings are commonly used due to their antimicrobial properties, but ... -
Defective ryanodine receptor N-terminus inter-subunit interaction is a common mechanism in neuromuscular and cardiac disorders
( Frontiers Media , 2022 , Article)The ryanodine receptor (RyR) is a homotetrameric channel mediating sarcoplasmic reticulum Ca<sup>2+</sup> release required for skeletal and cardiac muscle contraction. Mutations in RyR1 and RyR2 lead to life-threatening ... -
Disparate molecular mechanisms in cardiac ryanodine receptor channelopathies
( Frontiers Media , 2024 , Article)Aims: Mutations in the cardiac ryanodine receptor (RyR2) are associated with catecholaminergic polymorphic ventricular tachycardia (CPVT). This study investigates the underlying molecular mechanisms for CPVT mutations ... -

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 ... -
