Bioaugmentation to enhance degradation of acetochlor and pretilachlor in water and sediment under anaerobic conditions.

Chloroacetamide herbicides are widely used to control weeds globally. In this study, three acetochlor-degrading mixed cultures using nitrate, sulfate, and ferric iron as electron acceptors were isolated and determined for their degradation under anaerobic conditions. The degradation rates of all mixed pure cultures in a mineral medium were not much different at 1 µM, while the rates at 50 µM were in the order: mixed culture using nitrate > sulfate > ferric iron as electron acceptors, giving 6.

Prognosis of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: A Cohort Study of 216 Patients in an Inpatient Dermatology Department.

Introduction: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions. However, only a few studies have investigated the clinicodemographic and laboratory parameters predicting SJS and TEN outcomes other than mortality, such as severe complications or increased length of hospital stays. Our objectives are to identify admission risk factors predictive of severe complications and the accompanying clinical or biochemical markers associated with prolonged hospitalization.
