The Goldblatt's 2 kidney 1 clip (2K1C) rat animal model of renovascular hypertension is characterized by ischemic nephropathy of the clipped kidney. 2K1C rats were treated with a specific peroxisome proliferator-activated receptor δ (PPARδ) agonist, HPP593. Clipped kidneys from untreated rats developed tubular and glomerular necrosis and massive interstitial, periglomerular and perivascular fib...

BACKGROUND The treatment of giant and large paraclinoid aneurysms remains challenging. To improve exposure, facilitate the dissection of aneurysms, assure vascular control, reduce brain retraction and temporary occlusion time, enable simultaneous treatment of associated lesions, and achieve more successful treatment of "difficult" (atherosclerotic and calcified) aneurysms, we combined the skull...

The Voronoi diagram is a fundamental geometry structure widely used in various fields, especially in computer graphics and geometry computing. For a set of points in a compact 3D domain (i.e. a finite 3D volume), some Voronoi cells of their Voronoi diagram are infinite, but in practice only the parts of the cells inside the domain are needed, as when computing the centroidal Voronoi tessellatio...

BACKGROUND Osteopontin (Opn) is highly upregulated in many different animal models of renal disease, where it is suspected to participate in progression of the disease. In some models, angiotensin II (Ang II) seems to induce the elevated Opn production. Therefore, we examined the regulation of Opn in two-kidney, one-clip (2K1C) hypertensive rats, in which Ang II mediates the elevated blood pres...

Two-kidney, one-clip (2K1C) is a model of renovascular hypertension where we previously found an exaggerated intracellular calcium (Ca(i)(2+)) response to ANG II in isolated afferent arterioles (AAs) from the clipped kidney (Helle F, Vagnes OB, Iversen BM. Am J Physiol Renal Physiol 291: F140-F147, 2006). To test whether nitric oxide (NO) ameliorates the exaggerated ANG II response in 2K1C, we ...

Cumulative water- and electrolyte balance, plasma creatinine (PC), plasma renin activity (PRA), urinary prostaglandins (PGs) E2, and F2alpha and kallikrein (K) were studied in 40 male Wistar CHbb THOM rats (250 +/- 4 g SE). A solid silver clip (0.25 mm lumen) was applied to both renal arteries in 18 animals; 13 rats were sham-operated and nine remained intact. The analyses were performed during...
