Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

Experimental Physiology, EarlyView.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...

Translating physiology of the arterial chemoreflex into novel therapeutic interventions targeting carotid bodies in cardiometabolic disorders

The Journal of Physiology, EarlyView.
Abstract figure legend The carotid body develops aberrant high activity in chronic heart failure, resistant hypertension, obstructive sleep apnoea (OSA) and diabetes. Hyperactivity of the carotid body leads to both high tonicity and increased sensitivity of the arterial chemoreflex with resultant sympathoexcitation.

Sex‐specific differences in mortality and neurocardiac interactions in the Kv1.1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP)

The Journal of Physiology, EarlyView.
Abstract figure legend The Kcna1 knockout mouse model of sudden unexpected death in epilepsy (SUDEP) exhibits sex‐specific differences in SUDEP risk. Female mice exhibit a lower SUDEP risk than males, despite similar seizure characteristics and interictal cardiac function across sexes.

Presumptive Tests for Xylazine—A Computer Vision Approach

Analytical Science Advances, Volume 6, Issue 1, June 2025.
ABSTRACT Abuse of xylazine is an immediate global public health concern. We report the distinct and measurable colour changes when xylazine is exposed to the Mandelin, Marquis and Mecke presumptive test reagents. The colour changes observed with xylazine are distinct from those of drugs that give colour changes from the same presumptive tests.
