Cerebrovascular regulation during heat stress
Experimental Physiology, EarlyView.Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Three-dimensional color Doppler flow assessment of ischemic mitral regurgitation
, 2010 Purpose. Volume-rendered images of the mitral valve apparatus have enabled visualization of the MV leaflets, orifice, and submitral apparatus in a manner that is not possible using conventional 2-dimensional echocardiography.

Experimental Physiology, EarlyView.Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Trans-esophageal echocardiography for tricuspid and pulmonary valves
Annals of Cardiac Anaesthesia, 2009 Transesophageal echocardiography has been shown to provide unique information about cardiac anatomy, function, hemodynamics and blood flow and is relatively easy to perform with a low risk of complications.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation
The Journal of Physiology, EarlyView.Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...
