Cooperative calcium and zinc signaling underlies oxidant-induced neuronal injury [PDF]

, 2013
Intracellular zinc release triggered by oxidative injury leads to cellular K+ efflux and neuronal apoptosis. Low intracellular K+ enables protease and nuclease activation during cell death processes. Our laboratory has demonstrated that the reduction in

ATP-Sensitive Potassium Channels in Dopaminergic Neurons: Transducers of Mitochondrial Dysfunction

, 2001
ATP-sensitive potassium (KATP) channels directly couple the metabolic state of a cell to its electrical activity. Dopaminergic midbrain neurons express alternative types of KATP channels mediating their differential response to mitochondrial complex I ...

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Potassium channels in the mitochondria of unicellular eukaryotes and plants

, 2010
The functional characterisation of potassium channels found in the mitochondria of plants and unicellular eukaryotes is critically discussed herein, with a focus on the ATP-sensitive potassium channel and the large-conductance Ca2+-activated potassium ...

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Mitochondrial small conductance SK2 channels prevent glutamate-induced oxytosis and mitochondrial dysfunction.

, 2013
Small conductance calcium-activated potassium (SK2/K(Ca)2.2) channels are known to be located in the neuronal plasma membrane where they provide feedback control of NMDA receptor activity.

Age‐related differences in hydroxychloroquine‐associated adverse events: A pharmacovigilance study based on the FDA Adverse Event Reporting System

British Journal of Clinical Pharmacology, EarlyView.
Aims This real‐world pharmacovigilance study utilizes FDA Adverse Event Reporting System (FAERS) data (2004–2024) to characterize age‐related disparities in hydroxychloroquine (HCQ)‐associated adverse events (AEs), addressing gaps in age‐stratified risk assessment. Methods Disproportionality analysis (reporting odds ratios, RORs) and parametric Weibull

Blood pressure effects of SGLT2 inhibitors and GLP‐1 receptor agonists: Mechanisms, trial evidence and Real‐world data

British Journal of Clinical Pharmacology, EarlyView.
SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.
