The renal blood flow reserve in healthy humans and patients with atherosclerotic renovascular disease measured by positron emission tomography using [15O]H2O

EJNMMI Research, 2018
Background Microvascular function plays an important role in ARVD (atherosclerotic renovascular disease). RFR (renal flow reserve), the capacity of renal vasculature to dilate, is known to reflect renal microvascular function.

Behaviour of non-donor specific antibodies during rapid re-synthesis of donor specific HLA antibodies after antibody incompatible renal transplantation [PDF]

, 2013
Background: HLA directed antibodies play an important role in acute and chronic allograft rejection. During viral infection of a patient with HLA antibodies, the HLA antibody levels may rise even though there is no new immunization with antigen ...

Emerging key roles for P2X receptors in the kidney [PDF]

, 2013
P2X ionotropic non-selective cation channels are expressed throughout the kidney and are activated in a paracrine or autocrine manner following the binding of extracellular ATP and related extracellular nucleotides.

Dose and Time-Dependent Effects of Caffeine on Cardiovascular Changes Induced by Adenosine

Brazilian Archives of Biology and Technology, 2023
Adenosine is an important regulator within the cardiovascular system and modulates various processes through four distinct G protein-coupled receptors (A1, A2A, A2B, and A3), causing hypotension and reduced renal blood flow, which contributes to ischemia

Synchronized renal blood flow dynamics mapped with wavelet analysis of laser speckle flowmetry data. [PDF]

PLoS ONE, 2014
Full-field laser speckle microscopy provides real-time imaging of superficial blood flow rate. Here we apply continuous wavelet transform to time series of speckle-estimated blood flow from each pixel of the images to map synchronous patterns in ...
