Augmented β2-adrenergic signaling dampens the neuroinflammatory response following ischemic stroke and increases stroke size

Journal of Neuroinflammation, 2019
Background Ischemic stroke provokes a neuroinflammatory response and simultaneously promotes release of epinephrine and norepinephrine by the sympathetic nervous system.

Alterations in vasodilator-stimulated phosphoprotein (VASP) phosphorylation: associations with asthmatic phenotype, airway inflammation and β\u3csub\u3e2\u3c/sub\u3e-agonist use [PDF]

, 2006
Background Vasodilator-stimulated phosphoprotein (VASP) mediates focal adhesion, actin filament binding and polymerization in a variety of cells, thereby inhibiting cell movement.

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

The Association Between Maternal Asthma and Child Autism: A Systematic Review and Meta‐Analysis

Autism Research, EarlyView.
ABSTRACT Maternal asthma has been linked to child autism. In this study, we systematically reviewed observational studies published between July 2001 and February 2024 that assessed maternal asthma during pregnancy (exposure) and child autism (outcome). Databases searched included MEDLINE, CINAHL, EMBASE, and PsycINFO.

Heterogeneity in the projections and excitability of tyraminergic/octopaminergic neurons that innervate the Drosophila reproductive tract

Frontiers in Molecular Neuroscience
Aminergic nuclei in mammals are generally composed of relatively small numbers of cells with broad projection patterns. Despite the gross similarity of many individual neurons, recent transcriptomic, anatomic and behavioral studies suggest previously ...

Adaptations to iron deficiency: cardiac functional responsiveness to norepinephrine, arterial remodeling, and the effect of beta-blockade on cardiac hypertrophy. [PDF]

, 2002
BackgroundIron deficiency (ID) results in ventricular hypertrophy, believed to involve sympathetic stimulation. We hypothesized that with ID 1) intravenous norepinephrine would alter heart rate (HR) and contractility, 2) abdominal aorta would be larger ...

Beyond right or wrong: How partial credit scoring on multiple‐choice questions improves student performance and assessment perceptions

British Journal of Clinical Pharmacology, EarlyView.
Aims In this study, we examined the effects of assigning partial credit to selected answer choices on student performance and perceptions in a pharmacology course using Type A multiple‐choice questions (MCQs). Methods Partial credit scoring was incorporated into quizzes and exams in a 10‐week pharmacology course for postbaccalaureate premedical ...

The heartbreak of depression: 'Psycho-cardiac' coupling in myocardial infarction [PDF]

, 2017
Ample evidence identifies strong links between major depressive disorder (MDD) and both risk of ischemic or coronary heart disease (CHD) and resultant morbidity and mortality. The molecular mechanistic bases of these linkages are poorly defined. Systemic

Oxidative Phosphorylation in Uncoupled Mitochondria

BioEssays, EarlyView.
Brown adipose tissue (BAT) mediates non‐shivering thermogenesis (NST) through activation of uncoupling protein 1 (UCP1). Due to the uncoupled nature of BAT, oxidative phosphorylation is an underappreciated contributor to NST. Here, we discuss the implications of Inhibitory Factor 1 modulation, an endogenous inhibitor of ATP synthase, for BAT physiology.

Sex‐specific activation of SK current by isoproterenol facilitates action potential triangulation and arrhythmogenesis in rabbit ventricles [PDF]

, 2018
Sex has a large influence on cardiac electrophysiological properties. Whether sex differences exist in apamin‐sensitive small conductance Ca2+‐activated K+ (SK) current (IKAS) remains unknown.
