Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Cellular lipids regulate the conformational ensembles of the disordered intracellular loop 3 in β2-adrenergic receptor

iScience
Summary: The intracellular loops of G protein-coupled receptors (GPCRs) have been shown to play a key role in G protein coupling and selectivity. We recently showed that the intrinsically disordered third intracellular loop (ICL3) of β2-adrenergic ...

Slow calcium removal contributes to impaired lusitropic response to β‐adrenergic stimulation in HFpEF mice

The Journal of Physiology, EarlyView.
Abstract figure legend Heart failure with preserved ejection fraction (HFpEF) is the most common form of heart failure, yet major gaps remain in our understanding of its underlying mechanisms, disease progression and effective treatment strategies. Mice with HFpEF exhibited exercise intolerance and diastolic dysfunction in vivo, while isolated hearts ...

Cutaneous‐only hypersensitivity reaction presumed due to intravenous administration of atracurium in a dog

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Summary There are limited case reports of hypersensitivity reactions to neuromuscular blocking agents (NMBAs) in veterinary species, and none describe cutaneous‐only signs. This case report describes a Grade 1 cutaneous‐only hypersensitivity reaction to atracurium in a 7‐year‐old dog undergoing general anaesthesia for cataract surgery with bilateral ...

Recent advances in polyendocrine metabolic ovarian syndrome, formerly polycystic ovary syndrome, with emphasis on endocrine and metabolic dysfunction and cardiovascular risk

Journal of Internal Medicine, Volume 300, Issue 5, Page 590-609, November 2026.
Abstract Polyendocrine metabolic ovarian syndrome (PMOS), previously known as polycystic ovary syndrome, affects 10%–13% of women of reproductive age and remains underdiagnosed despite its substantial health burden. The introduction of the new PMOS nomenclature in 2026 reflects a fundamental shift in understanding the condition as a lifelong endocrine ...

Carvedilol Prevents UV-Induced Immunosuppression and Skin Carcinogenesis through a Mechanism Independent of β-Blockade

JID Innovations
Exposure to UVR suppresses the immune system, which plays a primary role in skin cancer etiology. The β-blocker carvedilol prevents UV-induced skin cancer, but the mechanism is unknown. This study examined the effects of carvedilol and its enantiomers on

Influence of Intravenous Norepinephrine Administration on Melatonin Plasma Concentration in Awake and Anaesthetised Healthy Adult Volunteers

Journal of Pineal Research, Volume 78, Issue 6, November 2026.
ABSTRACT Melatonin (MEL) is an endogenous hormone that regulates circadian rhythm, immune function and oxidative stress responses. Norepinephrine (NE), an endogenous catecholamine, increases blood pressure through the sympathetic nervous system and is commonly administered intraoperatively or in the clinically ill patient for hemodynamic support ...

Estrogen Receptor Beta Isoforms Interplay Integrates Nuclear and Extra‐Nuclear Signaling to Modulate Human Granulosa Cell Growth

The FASEB Journal, Volume 40, Issue 19, 15 October 2026.
Working model of ERβ isoform signaling in human granulosa cells. Upon E2 binding, ERβ1 activates ERE‐dependent transcription and represses AP‐1 activity through Jun/Fos interactions. In contrast, ERβ2, ERβ4, and ERβ5 lack E2 binding and ERE activity but promote AP‐1‐dependent transcription and counteract ERβ1 repression, including after phosphorylation

β2 Adrenoceptor Signaling Modulates Myoblast Differentiation via miR‐374b‐5p/GSK3β and miR‐326‐3p/Tnfrsf11a Axes

Cell Biology International, Volume 50, Issue 10, October 2026.
ABSTRACT Myoblast differentiation is a crucial step of skeletal muscle regeneration and is impaired in the absence of the β2 adrenoceptor (ADRβ2). Since miR‐374b and miR‐326 regulate cell differentiation, this study investigated if ADRβ2 regulates myoblast differentiation via miR‐374b‐5p and miR‐326‐3p. Primary myoblasts from ADRβ2 knockout (β2KO) mice
