Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

G protein-coupled receptor kinase 2-mediated phosphorylation of ezrin is required for G protein-coupled receptor-dependent reorganization of the actin cytoskeleton [PDF]

, 2005
G protein-coupled receptor kinase 2 (GRK2) phosphorylates and desensitizes activated G protein-coupled receptors (GPCRs). Here, we identify ezrin as a novel non-GPCR substrate of GRK2. GRK2 phosphorylates glutathione S-transferase (GST)-ezrin, but not an

Δ9 Tetrahydrocannabinol and cannabis extracts differentially improve adipoinsular dysfunction in diet‐induced obesity

The Journal of Physiology, EarlyView.
Abstract figure legend THC and extract administered to diet‐induced obese mice reduced body weight and fat storage. Extract, but not THC, improved glucose clearance by a mechanism that may include restoring adipoinsular function. Abstract Diet‐induced obesity (DIO) is associated with dysregulated adipoinsular axis and endocannabinoid system (eCBS ...

Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

Regional electrical differences and arrhythmia in the rat atria: Role of sympathetic nerve distribution and function

The Journal of Physiology, EarlyView.
Abstract figure legend Atrial fibrillation commonly develops in the left atrium and pulmonary veins (PVs), and can be triggered by sympathetic nerve activity. Here, we examined regional atrial differences in sympathetic nerve distribution and function in the rat.

Identification of ß-adrenergic receptor subtypes mediating relaxation in isolated equine ileum

, 1997
OBJECTIVE: To identify beta-adrenergic receptor subtypes in ileum smooth muscle of the horse. SAMPLE POPULATION: Isolated strips of equine longitudinal ileum smooth muscle and membrane preparations from smooth muscle of the intestinal wall ...

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

Beta-adrenergic receptor regulation and airway inflammation

, 2005
There is ongoing concern that regular use of β2-agonists without additional use of inhaled steroids may contribute to an adverse outcome of asthma, which may in part be due to desensitization of the β2-adrenergic receptor (Chapter7 ). Therefore, there is

Beta-Adrenergic Responsiveness of the Gastrointestinal-Tract in Diabetic Rats

, 1992
WOS: A1992JU94200002PubMed ID: 1360656Recently, decreased gastrointestinal beta-adrenergic responses in experimental diabetes have been demonstrated. Gastrointestinal responses to beta-adrenoceptor agonists are impaired in both insulin-dependent and non ...

Mechanism of Pingchuanning in Attenuating Asthma Based on UHPLC‐Q‐Orbitrap HRMS and Network Pharmacology Analysis

Biomedical Chromatography, Volume 40, Issue 12, December 2026.
ABSTRACT An ultrahigh‐performance liquid chromatography coupled with quadrupole‐Orbitrap high‐resolution mass spectrometry (UHPLC‐Q‐Orbitrap HRMS) method was applied to characterize Pingchuanning (PCN) decoction and its absorbed serum constituents in asthmatic rats.
