Head-to-head comparison of V-A ECMO, Impella and ECPELLA in normal ovine hearts [PDF]
Scientific ReportsTemporary mechanical circulatory support (MCS), including veno-arterial extracorporeal membrane oxygenation (ECMO) and micro-axial pumps (Impella), is increasingly used in clinical practice for refractory circulatory failure.

Extracorporeal Carbon Dioxide Removal in Acute Respiratory Distress Syndrome: Physiologic Rationale and Phenotype-Based Perspectives [PDF]
MedicinaAcute respiratory distress syndrome (ARDS) is a major cause of morbidity and mortality despite decades of progress in ventilatory support. Mechanical ventilation, while essential for oxygenation, may exacerbate lung injury through excessive mechanical ...

Physiologic blood flow is turbulent [PDF]
Scientific Reports, 2020 AbstractContemporary paradigm of peripheral and intracranial vascular hemodynamics considers physiologic blood flow to be laminar. Transition to turbulence is considered as a driving factor for numerous diseases such as atherosclerosis, stenosis and aneurysm.

Fluid Analysis of Double-Layered Blood Flow through a Tapered Overlapping Stenosed Artery with a Porous Wall [PDF]
Journal of Heat and Mass Transfer Research, 2022 In this present work, we examine the fluid of double-layered blood flow through a tapered overlapping stenosed artery with a porous wall. This two-layered blood flow problem comprises the peripheral layer as Newtonian fluid flows and the central core ...

Reciprocating intestinal flows enhance glucose uptake in C. elegans
Scientific Reports, 2022 Despite its physiological and pathological importance, the mechanical relationship between glucose uptake in the intestine and intestinal flows is unclear. In the intestine of the nematode Caenorhabditis elegans, the defecation motor program (DMP) causes

Physiological non-Newtonian blood flow through single stenosed artery [PDF]
Theoretical and Applied Mechanics, 2016 A numerical simulation to investigate the Non-Newtonian modeling effects on physiological flows in a three dimensional idealized artery with a single stenosis of 85% severity is given. The wall vessel is considered to be rigid.

Self-organized canals enable long-range directed material transport in bacterial communities
eLife, 2022 Long-range material transport is essential to maintain the physiological functions of multicellular organisms such as animals and plants. By contrast, material transport in bacteria is often short-ranged and limited by diffusion. Here, we report a unique

Pulmonary capillary recruitment and distention in mammalian lungs: species similarities
European Respiratory Review, 2022 Pulmonary arterial pressure rises minimally during exercise. The pulmonary microcirculation accommodates increasing blood flow via recruitment of pulmonary capillaries and, at higher flows, by distention of already perfused capillaries.

High bias gas flows increase lung injury in the ventilated preterm lamb. [PDF]
PLoS ONE, 2012 BACKGROUND: Mechanical ventilation of preterm babies increases survival but can also cause ventilator-induced lung injury (VILI), leading to the development of bronchopulmonary dysplasia (BPD).
