Diabetes alters vascular mechanotransduction data: Pressure-induced regulation of mTor and associated signaling in the rat inferior vena cava

Data in Brief, 2017
Diabetes is a multifaceted disease with various etiologies. The complexity of this pathology creates a myriad of factors that must be considered when addressing surgical outcomes and prognosis.

Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

Artificial Organs, EarlyView.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

Diabetes alters vascular mechanotransduction data: Pressure-induced regulation of Nf-kapa-B p65 and translational associated signaling in the rat inferior vena cava

Data in Brief, 2017
Diabetic patients have a high rate of vein graft failure due to attrition or vessel occlusion that cause recurrent ischemic events or vein graft. Veins grafted into a high-pressure arterial environment must undergo vascular remodeling to better handle ...

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

The Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, Volume 604, Issue 16, Page 6872-6894, 15 August 2026.
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 ...
