Retinal blood flow reversal quantitatively monitored in out-of-plane vessels with laser Doppler holography [PDF]
arXiv, 2020 Laser Doppler holography is a planar blood flow imaging technique recently introduced in ophthalmology to image human retinal and choroidal blood flow non-invasively. Here we present a digital method based on the Doppler spectrum asymmetry that reveals the local direction of blood flow with respect to the optical axis in out-of-plane vessels.

Photoacoustic vector tomography for deep hemodynamic imaging [PDF]
arXiv, 2022 Non-invasive imaging of deep blood vessels for mapping hemodynamics remains an open quest in biomedical optical imaging. Although pure optical imaging techniques offer rich optical contrast of blood and have been reported to measure blood flow, they are generally limited to surface imaging within the optical diffusion limit of about one millimeter ...

Dependency of Renal Blood Flow on Prostaglandin Synthesis in the Dog
Circulation Research, 1973 Inhibition of prostaglandin synthesis in chloralose-anesthetized dogs reduced renal blood flow, and this reduction closely correlated (r=0.92 ...

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer
Advanced Biology, EarlyView.Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundThe role of kidney hypoxia is considered pivotal in the progression of chronic kidney disease. A widely used method to assess kidney oxygenation is blood oxygen level dependent (BOLD)–magnetic resonance imaging (MRI), but its interpretation ...

Mathematical modeling of blood flow through arterial bifurcation [PDF]
arXiv, 2020 The blood vascular system consists of blood vessels such as arteries, arterioles, capillaries and veins that convey blood throughout the body. The pressure difference which exists between the ends of the vessels provides the living force required to the flow of blood.
