Diffusion boundary layers ameliorate the negative effects of ocean acidification on the temperate coralline macroalga Arthrocardia corymbosa. [PDF]
PLoS ONE, 2014 Anthropogenically-modulated reductions in pH, termed ocean acidification, could pose a major threat to the physiological performance, stocks, and biodiversity of calcifiers and may devalue their ecosystem services.

Physiological confounders of renal blood flow measurement
Magnetic Resonance Materials in Physics, Biology and Medicine, 2023 Abstract Objectives Renal blood flow (RBF) is controlled by a number of physiological factors that can contribute to the variability of its measurement. The purpose of this review is to assess the changes in RBF in response to a wide range of physiological confounders and derive practical recommendations on patient ...

Ultrasound‐Controlled Swarmbots Under Physiological Flow Conditions
Advanced Materials Interfaces, 2022 AbstractNavigation of microrobots in living vasculatures is essential in realizing targeted drug delivery and advancing non‐invasive surgeries. Acoustically‐controlled “swarmbots” are developed based on the self‐assembly of clinically‐approved microbubbles (MBs). Ultrasound is noninvasive, penetrates deeply into the human body, and is well‐developed in

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.

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.
