COMPUTATIONAL INVESTIGATIONS OF RED BLOOD CELL MECHANICAL TRAUMA AND OF DISEASED RENAL ARTERY HEMODYNAMICS
… damage in flow and the hemodynamics of diseased renal arteries; specifically, those with renal artery stenoses or aneurysms.

Evaluation of patients with resistant arterial hypertension before and after pharmacological treatment correction or a renal artery sympathetic denervation procedure /
… analysis of patients who underwent sympathetic renal artery denervation procedure in 2012-2017. There was a statistically significant blood pressure (BP) reduction in after 6 months in groups. However, decrease in systolic BP was significantly higher in interventional group -33.8 mm Hg (± 3.01) …

Einfluß unterschiedlicher klinischer und anamnestischer Parameter auf die Erfolgsaussichten der perkutanen transluminalen renalen Angioplastie : eine retrospektive Studie
… a percutaneous transluminal angioplasty of the renal artery. It was examinated in which way different clinal and anamnestic parameters (sex, age, nicotin-abusus, use of stens, pathogenesis of the stenosis) did influence the long-time results of percutaneous transluminal angioplasty of the renal …

Renal Blood Oxygen Level Dependent (BOLD) Magnetic Resonance Imaging with an Acute Furosemide Stimulus as a Tool to Evaluate Kidney Physiology in Patients Suspected of Renal Artery Stenosis
… tool to detect kidney oxygenation in a number of renal pathologic states. Specifically, it has been evaluated as a potential prognostic tool to determine which patients with severe renal artery stenosis may benefit from revascularization procedures. Currently, management of renal artery stenosis …

Rezistentiška arterine hipertenzija sergančių pacientų įvertinimas koregavus medikamentinį gydymą bei po simpatinės inkstų arterijų denervacijos /
… analysis of patients who underwent sympathetic renal artery denervation procedure in 2012-2017. There was a statistically significant blood pressure (BP) reduction in after 6 months in groups. However, decrease in systolic BP was significantly higher in interventional group -33.8 mm Hg (± 3.01) …

Development of a Phantom Tissue for Blood Perfusion Measurements and Noninvasive Blood Perfusion Estimation in Living Tissue
… by temporarily occluding blood flow through the renal artery and vein. The perfusion estimated by the convective perfusion probe was in good agreement with that of the metered flow of perfusate into the liver model. The liver tests indicated that the probe can be used to detect small changes in …

Extracellular matrix- and pluripotent stem cell-based tissue engineering of the kidney
… which should be recellularized with human renal precursor cells and endothelial cells differentiated from induced pluripotent stem cells. This approach required the development of a perfusion bioreactor and control software, which enabled the de- and recellularization of the kidneys as well …

Image Segmentation, Parametric Study, and Supervised Surrogate Modeling of Image-based Computational Fluid Dynamics
… of a 3-D pipe with the dimensions of a human renal artery. We investigated the relationship between stenosis severity and Resistive index (RI). We also explored how pulsatile parameters like heart rate or pulsatile pressure gradient affect RI. As the process of ICFD analysis is based on …

Non-specific aortic arteritis (Takayasu's disease) : the Cape Town experience
… with ruptured aneurysm. Hypertension due to renal artery stenosis or to coarctation was the commonest presentation (76%). 103 (47%) patients had cardiac disease (hypertensive cardiac failure or aortic incompetence.) Upper or lower limb claudication was present in 77 patients with gangrene in …

Outcomes of renal transplantation in patients with lupus nephritis: a single centre study in Cape Town
… Although most LN patients are suitable for renal transplantation when they develop end stage renal disease (ESRD), the risk of recurrence of LN post-transplantation can be as high as 30%. Since the outcomes of renal transplantation in ESRD-LN patients has not been adequately studied in South …

Virtual Reality Simulations and Interventional Radiology
… treated simulated patients suffering from renal artery stenosis (RAS) and carotid artery stenosis (CAS). Endovascular skills transfer was tested using the P-Lab as an approximation of the human catheterization laboratory. A group of endovascular novices were evaluated in the P-Lab and the …

Renal blood flow in the conscious, unrestrained rat
… is to test the hypothesis that the rate of renal blood flow remains constant under normal physiological conditions. Methods were developed for long term studies of renal blood flow (using the Doppler flow probe) and blood pressure in the conscious unrestrained rat. Special care was taken to …

Are gadolinium contrast media really less nephrotoxic than iodine agents in radiographic examinations? A comparison in relation to their ability to attenuate x-rays in a pig model
… into the balloon-occluded (10-minutes) right renal artery of left-sided nephrectomized pigs. Test solutions: 1) 0.5M gadopentetate (1.96 Osm/kg H2O), 0.5M gadodiamide (0.78 Osm/kg), 0.5M iohexol (190 mg I/mL; 0.42 Osm/kg), 0.18M iohexol (70 mg I/mL; with an x-ray attenuation equal to that of …

THE CHARACTERIZATION AND REGULATION OF BENZODIAZEPINE BINDING SITES IN THE MAMMALIAN RETINA, CEREBRAL CORTEX AND KIDNEY
… K(d), ∼11 nM). Drug specificity studies with renal membranes showed that inhibition of [³H]FLU binding by various BZD's did not correlate either with their pharmacologic potency as anxiolytic agents or with their potency as inhibitors of [³H]FLU binding in the brain. An intrarenal distribution …

Η επίδραση των εμποτισμένων με διάφορες φαρμακευτικές ουσίες μεταλλικών ενδοπροθέσεων στο τοίχωμα των νεφρικών αρτηριών
Σύγχρονες μελέτες, που αφορούν στη χρήση των εμποτισμένων με διάφορες ουσίες μεταλλικών ενδοπροθέσεων στα στεφανιαία, καρωτιδικά και μηριαία αγγεία, καταδεικνύουν την ικανότητά τους να προσφέρουν καλύτερα κλινικά και αγγειογραφικά αποτελέσματα. Με βάση τις αναφορές αυτές χρησιμοποιήσαμε μεταλλικές …
