Example Sentences:
(1) We have previously shown that, with moderate hydration (2.5 L) of the recipient, together with rapid infusion of 250 ml of mannitol 20% just before clamp removal, the incidence of ARF decreased to below 10%.
(2) The factors predisposing to and complicating acute renal failure (ARF) in the medical intensive care unit (ICU), and their relative influence on outcome during ARF are unclear.
(3) Frusemide has been given to try to prevent this change in glycerol-induced ARF because of its effect in redistributing renal blood flow from medulla to cortex.
(4) Five different human ARFs have been identified by cDNA cloning.
(5) Studies of calcium antagonists in humans with ARF have been confined to patients undergoing renal transplantation.
(6) With an additional procedure of adrenalectomy (BN + Ax), the enzyme activity failed to show any increase in ARF rats produced by BN.
(7) Glycerol-induced ARF in rats or rabbits has been studied to investigate the pathogenesis of myoglobinuria-associated ARF.
(8) The results demonstrate that redistribution of ARF to the vesicle membrane correlates with the intravesicular pH established by a vacuolar-type H(+)-ATPase.
(9) Uptake of tetraethylammonium with or without an H+ gradient was decreased in membrane vesicles from ARF rats compared with normal rats.
(10) Hybridization of a bovine ARF 2 cDNA under low stringency with mammalian poly(A)+ RNA resulted in multiple bands that were subsequently assigned to the known ARF genes using ARF-specific oligonucleotide probes.
(11) (2) The interstitium of the cortex and of the outer stripe of the outer medulla is significantly widened in most cases of ARF.
(12) These were characterized by ballooning of the capillaries, thickening and splitting of glomerular basement membrane (GMB), fibrin thrombi in the capillaries, and mesangial cell proliferation most prominently seen in Ecchis carinatus bites resulting in ARF.
(13) ARF was centered in the inner city, where the incidence among black children reached 15.21.
(14) The renin-angiotensin system does not seem to contribute to the reduction of renal function in norepinephrine-induced ARF in dogs.
(15) It is concluded that reciprocal changes in RA and RE are the immediate cause of filtration failure in this form of ARF and that, in the virtual absence of filtration, tubular leakage can play no important role.
(16) No significant differences were present between both groups when they were analyzed for ARF incidence (15% vs 23.8%); overall incidence was 19.5%.
(17) Hospital records from all Swedish children 0-15 years old diagnosed as having acute rheumatic fever (ARF) during 1971-80 were studied.
(18) The spectrum and outcome of acute renal failure (ARF) were studied in 205 children aged between 1 month and 12 yr.
(19) Its presence in Giardia is consistent with the view that ARF emerged before the divergence of this protozoan from other eukaryotes (approximately 1.5 billion years ago), and that an ARF-like protein may have been the ancestor of several other classes of signal-transducing guanine nucleotide-binding proteins, including the alpha subunits of the heterotrimeric G proteins.
(20) The rate of carditis (3 of 10 patients) was similar to that in older studies of adults with ARF.
