Echocardiography during submaximal isometric exercise in children with repaired coarctation of the aorta compared with controls [PDF]

, 2019
Objective Patients with repaired coarctation (RCoA) remain at higher risk of cardiac dysfunction, initially often only detected during exercise. In this study, haemodynamics of isometric handgrip (HG) and bicycle ergometry (BE) were compared in patients ...

Structure Learning in Coupled Dynamical Systems and Dynamic Causal Modelling [PDF]

, 2019
Identifying a coupled dynamical system out of many plausible candidates, each of which could serve as the underlying generator of some observed measurements, is a profoundly ill posed problem that commonly arises when modelling real world phenomena.

Haemodynamic Response to Moderate Thermal Stress in Pregnancy

Annals of Medicine, 1991
The effect of a moderate heat stress on cardiovascular responses was studied: group I consisted of 15 healthy non-pregnant women, group II of 23 women 13-14 weeks pregnant and group III of 23 women 36-37 weeks pregnant. Heart rate, stroke volume, cardiac output, arterial blood pressure and peripheral vascular resistance were recorded every 5-10 minutes

Mitochondrial Transplantation via Magnetically Responsive Artificial Cells Promotes Intracerebral Hemorrhage Recovery by Supporting Microglia Immunological Homeostasis

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
A type of magnetically responsive artificial cells (ACs) has been developed, demonstrating the loading of mitochondria and self‐enclosure processes to ensure the protection of mitochondrial transport via the bloodstream. The treatment with ACs effectively transplanted mitochondria around the lesion, thereby improving neurological recovery by supporting

Comparison of Oral Pregabalin and Clonidine Premedication in Attenuating Pressor Response to Laryngoscopy and Intubation: A Prospective Interventional Study

Journal of Clinical and Diagnostic Research
Introduction: Laryngoscopy and intubation during the induction of general anaesthesia can lead to sympathetic system-mediated haemodynamic pressor response, which, if exaggerated, may lead to hazardous complications like myocardial ischaemia, arrhythmias,

β-adrenergic-mediated dynamic augmentation of sarcolemmal CaV 1.2 clustering and co-operativity in ventricular myocytes. [PDF]

, 2019
Key pointsPrevailing dogma holds that activation of the β-adrenergic receptor/cAMP/protein kinase A signalling pathway leads to enhanced L-type CaV 1.2 channel activity, resulting in increased Ca2+ influx into ventricular myocytes and a positive ...

Effect of Dexmedetomidine on Haemodynamic Responses to Laryngoscopy and Intubation

Drugs in R & D, 2006
Dexmedetomidine reduces the dose requirements for opioids and anaesthetic agents. The purpose of this study was to evaluate the effect of a single pre-induction intravenous dose of dexmedetomidine 1 microg/kg on cardiovascular response resulting from laryngoscopy and endotracheal intubation, need for anaesthetic agent and perioperative haemodynamic ...
