Automatic Delineation of Kidney Region in DCE-MRI [PDF]

open access: yesarXiv, 2019
Delineation of the kidney region in dynamic contrast-enhanced magnetic resonance Imaging (DCE-MRI) is required during post-acquisition analysis in order to quantify various aspects of renal function, such as filtration and perfusion or blood flow. However, this can be obfuscated by the Partial Volume Effect (PVE), caused due to the mixing of any single

Effects of Restoration of Blood Flow on the Development of Aortic Atherosclerosis in ApoE −/− Mice With Unilateral Renal Artery Stenosis [PDF]

open access: yes, 2016
BACKGROUND: Chronic unilateral renal artery stenosis (RAS) causes accelerated atherosclerosis in apolipoprotein E-deficient (ApoE(-/-)) mice, but effects of restoration of renal blood flow on aortic atherosclerosis are unknown. METHODS AND RESULTS: Male

Intrarenal Role of Angiotensin II: HOMEOSTATIC REGULATION OF RENAL BLOOD FLOW IN THE DOG

open access: yesCirculation Research, 1973
The analogue, l-sarcosine-8-alanine-angiotensin II, a specific competitive antagonist of the vascular action of angiotensin II in the rat, blocked the decrease in renal blood flow after a single intrarenal injection of angiotensin II but not after an ...

Hemodynamical Behavior Analysis of Anemic, Diabetic, and Healthy Blood Flow in the Carotid Artery [PDF]

open access: yes
The influence of blood rheology on hemodynamic parameters is investigated using Computational Fluid Dynamics on blood flow through the human carotid artery. We performed three-dimensional modeling and simulation to study blood flow through the carotid artery, which is divided into internal and exterior parts with a decreased radius.

Distribution of Cytoskeletal Components in Endothelial Cells in the Guinea Pig Renal Artery [PDF]

open access: yes, 2012
The cytoskeletal components of endothelial cells in the renal artery were examined by analysis of en face preparations under confocal laser scanning microscopy. Renal arterial endothelial cells were shown to be elongated along the direction of blood flow,

RELATIONS OF EFFECTIVE RENAL BLOOD FLOW AND GLOMERULAR FILTRATION TO TUBULAR EXCRETORY MASS IN NORMAL MAN.

open access: yesJournal of Clinical Investigation, 1940
In 1938 Smith, Goldring and Chasis (12) described methods for measuring the "effective renal blood flow" (diodrast clearance) and the " tubular excretory mass " (diodrast Tm) by the excretion of diodrast at low and high plasma levels.

Living Microalgae‐Based Magnetic Microrobots for Calcium Overload and Photodynamic Synergetic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...

971-54 A Non-invasive Method of Visually Assessing Renal Perfusion Using a Newly Developed Intravenous Ultrasound Contrast [PDF]

open access: yes, 1995
Present methods of quantifying renal artery blood flow (RABF) in renovascular disease require either radionuclide techniques or invasive delivery of radiographic or ultrasound contrast.
