Molecular characterization of D variants in Brazilian blood donors and their association with RhCE and Duffy phenotypes

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Serological classification of RhD‐negative and weak D is often insufficient in admixed populations, where diverse RHD variants have clinical implications. In Brazil's highly admixed population, RhD interpretation and donor–recipient matching are particularly challenging.

Oxidative stress and impaired cardiovagal baroreflex sensitivity in young adults with post‐traumatic stress disorder

open access: yesExperimental Physiology, EarlyView.
Abstract Post‐traumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, yet the underlying physiological characterization in young adults remain unclear. This study examines whether autonomic and/or vascular dysfunction predominates as an early precursor to CVD development in young adults with PTSD and explores the

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance
