Contrasting preganglionic and postganglionic effects of phenylephrine on parasympathetic control of heart rate

, 1991
Previous reports indicate that alpha-adrenergic agonists modulate vagal control of heart rate. In the rat, phenylephrine inhibition of vagal-stimulated bradycardia may be occurring at any of a number of sites along the cardiac parasympathetic pathway ...

ATP Release and Purinergic Signaling Potentiate β‐Adrenergic Effects on Brown Adipocytes

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Brown adipose tissue (BAT) specializes in energy consumption and thermogenesis in response to cold stress. Brown adipocytes (BA) express purinergic receptors, yet little is known about the source of extracellular ATP and the role of purinergic signaling, and the potential interaction with β‐adrenergic signaling.

Complications and outcomes of standing flank versus ventral midline laparotomy for equine nephrosplenic entrapment

Equine Veterinary Education, Volume 38, Issue 10, Page e736-e743, October 2026.
Summary Background Nephrosplenic entrapment (NSE) is a common surgical colic in horses. Ventral midline laparotomy (VML) under general anaesthesia (GA) is the standard approach, whereas standing flank laparotomy (SFL) is an alternative approach for surgical correction. However, direct comparisons between these approaches are lacking.

Surgical management of an odontogenic collision tumour and oronasal fistula in a 14‐year‐old Warmblood mare

Equine Veterinary Education, Volume 38, Issue 10, Page e706-e713, October 2026.
Summary Tumours of the equine nasal passages and paranasal sinuses are uncommon, and collision tumours, two independent neoplasms arising adjacently, are exceptionally rare. Cementomas and osteolipomas are both benign, slow‐growing tumour types, but are only sparsely described in horses.

Oxadiazolone‐Triazole Derivatives as a New Scaffold for Modulation of Angiotensin II‐Induced Vascular Contraction

ChemMedChem, Volume 21, Issue 17, 14 September 2026.
A novel series of candidate AT1 receptor antagonists based on oxadiazolone‐triazole scaffolds was designed and synthesized. Most compounds reduced angiotensin II‐induced vascular contraction in an initial biological screening, with compound 7f emerging as the most active derivative.

Development of a Multi‐Organ Microphysiological (MPS) Model to Study Age‐Related Comorbidities

Advanced Biology, Volume 10, Issue 9, September 2026.
This study developed a human‐based organ‐on‐a‐chip model for the comorbidity of sarcopenia and hypertrophic cardiomyopathy (HCM). The microphysiological system (MPS) co‐cultured skeletal muscle of sarcopenia pathology, cardiomyocytes of HCM pathology, and healthy hepatocytes in a circulated serum‐free common medium.
