Retroperitoneal fibrosis (RPF) is a rare disease, hallmarked by inflammation and deposition of fibrous tissue around the abdominal aorta. This process may spread contiguously and involve adjacent structures, leading to many complications, among which the most frequent and most severe is ureteral obstruction. The condition usually has idiopathic origin (idiopathic retroperitoneal fibrosis - IRF)...

Viable cells of Micrococcus luteus secrete a factor, which promotes the resuscitation and growth of dormant, nongrowing cells of the same organism. The resuscitation-promoting factor (Rpf) is a protein, which has been purified to homogeneity. In picomolar concentrations, it increases the viable cell count of dormant M. luteus cultures at least 100-fold and can also stimulate the growth of viabl...

Angiotensin (5 ng/kg/min and 50 ng/kg/min) was infused directly into the left renal artery of anesthetized dogs in order to examine its effects on the renal func tion. Urinary volume, creatinine clearance (GFR), PAH-clearance (RPF) and electrolyte excretion were decreased by infusion of angiotensin in a small dose. On the other hand extreme reductions of urinary volume, GFR, RPF and electrolyte...

In 61 patients, 61 consecutive implants were placed immediately after extraction of one anterior or premolar maxillary tooth. One of 3 surgical approaches based on rotated full (RPF) or rotated split (RSPF) palatal flaps, with and without the use of barrier membranes to enable primary soft tissue closure, was applied. A bovine bone mineral graft was used in all cases. At the time of implant pla...

The study evaluated the effect of supplementation rumen protected choline (RPC) and fat (RPF) alone in combination, injection Vit-E + selenium on feed intake, blood metabolic profile postpartum fertility transition Gir cows. Forty advanced (8 months) pregnant cows were divided into five equal groups (T1 to T5, n=8) managed individually from 30 days prepartum till 60 postpartum. Cows T1 group fe...

Systemic administration of L-arginine alters renal haemodynamics in humans. We examined whether L-arginine-induced vasodilation of the renal vasculature is related to an increased production and release of NO by comparing the effects of L- and D-arginine on renal endothelium-dependent vasodilation. In a double-blind randomized cross-over study including 20 young, healthy male white subjects (ag...

Introduction: Retroperitoneal Fibrosis (RPF) is a clinicopathological condition characterized by inflammatory fibrotic reaction around infrarenal aorta, iliac vessels and surrounding retroperitoneum with myriad presentations. This case report shows how a Deep Vein Thrombosis (DVT) and subsequent Pulmonary Embolism (PE) can be a potential complication of this disease. A potential temporal associ...

BACKGROUND Prospective evaluation of the value of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels in monitoring disease activity and treatment response in patients with idiopathic retroperitoneal fibrosis (RPF). METHODS This study included 57 patients with idiopathic RPF receiving tamoxifen monotherapy with at least 8 months follow-up. Clinical, laboratory and radiolo...

OBJECTIVES Several reports suggest that enhanced generation or actions of nitric oxide (NO) have been implicated in the pathogenesis of glomerular hyperfiltration and hyperperfusion that occurs in early diabetes. However, the precise role of altered NO generation in the pathogenesis of diabetic nephropathy is unclear. The present study was aimed at investigating the role of nitric oxide in the ...
