Long-term renal outcome was assessed.

Results: Followup was 2 to 16 years (median 3.6). Renal insufficiency developed at the end of followup in 44 patients (36.5%). Serum creatinine at hospital admission, nadir Selleck Nutlin3 serum creatinine, initial creatinine clearance and renal parenchymal echogenicity were significant

predictors of the final renal outcome (p < 0.05). Patient age at diagnosis (2 or less vs greater than 2 years), upper tract dilatation, the presence or absence of vesicoureteral reflux, popoff mechanisms and bladder dysfunction had no significant impact on future renal function. On multivariate analysis nadir serum creatinine was the only independent prognostic factor.

Conclusions: Our data confirm the high prognostic value of nadir creatinine after primary valve ablation. Also, initial serum creatinine, creatinine clearance and renal parenchymal echogenicity on initial renal ultrasound correlate significantly with long-term renal function in children this website with posterior urethral valves.”
“There is very limited information on the biotransformation of organochlorine pesticide chlordane by microorganisms, and no systematic study on the metabolic products and pathways

for chlordane transformation by wood-rot fungi has been conducted. In this study, trans-chlordane was metabolized with the wood-rot fungi species Phlebia lindtneri, Phlebia brevispora and Phlebia aurea, which are capable of degrading polychlorinated dibenzo-p-dioxin and heptachlor epoxide. At the end of 42 days of incubation, over 50% of trans-chlordane was degraded by the fungal treatments in pure cultures. These fungi transformed trans-chlordane to at least eleven metabolites including a large amount of hydroxylated products such as 3-hydroxychlordane, chlordene chlorohydrin, heptachlor diol, monohydroxychlordene and dihydroxychlordene. P. lindtneri

particularly can metabolize oxychlordane, Apoptosis inhibitor a recalcitrant epoxide product of chlordane, into a hydroxylated product through substitution of chlorine atom by hydroxyl group. The present results suggest that hydroxylation reactions play an important role in the metabolism of trans-chlordane by these Phlebia species. Additionally, transformation of trans-chlordane and production of hydroxylated metabolites were efficiently inhibited by the addition of cytochrome P450 inhibitors, piperonyl butoxide and 1-aminobenzotriazole, demonstrating that fungal cytochrome P450 enzymes are involved in some steps of trans-chlordane metabolism, particularly in the hydroxylation process.
