Unveiling mysteries of micro-porous structures in xylem vascular of plants: characterising nutrient transport using electro-hydrodynamics

Flow
We unveil the flow and ionic transport characteristics of xylem vessels to establish a correlation between in situ electrical energy generation and plant bioregulation.

Theory to predict shear stress on cells in turbulent blood flow.

PLoS ONE, 2014
Shear stress on blood cells and platelets transported in a turbulent flow dictates the fate and biological activity of these cells. We present a theoretical link between energy dissipation in turbulent flows to the shear stress that cells experience and ...

Assessment of wall elasticity variations on intraluminal haemodynamics in descending aortic dissections using a lumped-parameter model. [PDF]

PLoS ONE, 2015
Descending aortic dissection (DAD) is associated with high morbidity and mortality rates. Aortic wall stiffness is a variable often altered in DAD patients and potentially involved in long-term outcome. However, its relevance is still mostly unknown.

Modeling Food Web Interactions in Benthic Deep-Sea Ecosystems: A Practical Guide [PDF]

Oceanography, 2009
Deep-sea benthic systems are notoriously difficult to sample. Even more than for other benthic systems, many flows among biological groups cannot be directly measured, and data sets remain incomplete and uncertain.

Effect of maternal oxytocin on umbilical venous and arterial blood flows during physiological-based cord clamping in preterm lambs.

PLoS ONE, 2021
BackgroundDelayed umbilical cord clamping (UCC) after birth is thought to cause placental to infant blood transfusion, but the mechanisms are unknown.

Determinants of forced expiratory flows in newborn infants [PDF]

, 1982
Maximal flows at functional residual capacity (VmaxFRC) from partial expiratory flow-volume (PEFV) curves (achieved with rapid compression of the chest) were obtained on 11 healthy newborn babies. Mean VmaxFRC, size corrected by dividing absolute values

Responses of hepatic blood flows to changes in intake in sheep: a meta-analysis

Animal, 2009
This work set out to establish the response equations for hepatic blood flows in sheep and the contribution of hepatic arterial flow to hepatic venous blood flow due to changes in intake levels at constant diet composition.

Red Blood Cells: Tethering, Vesiculation, and Disease in Micro-Vascular Flow

Diagnostics, 2021
The red blood cell has become implicated in the progression of a range of diseases; mechanisms by which red cells are involved appear to include the transport of inflammatory species via red cell-derived vesicles.

How Much PEEP Does High Flow Deliver via Tracheostomy? A Literature Review and Benchtop Experiment

Critical Care Research and Practice, 2021
Background. High flow tracheostomy (HFT) is a commonly used weaning and humidification strategy for tracheostomised patients, but little is known as to how much PEEP or mechanical benefit it offers.
