Role for Drs2p, a P-type ATPase and potential aminophospholipid translocase, in yeast late Golgi function.

ADP-ribosylation factor appears to regulate the budding of both COPI and clathrin-coated transport vesicles from Golgi membranes. An arf1Delta synthetic lethal screen identified SWA3/DRS2, which encodes an integral membrane P-type ATPase and potential aminophospholipid translocase (or flippase). The drs2 null allele is also synthetically lethal with clathrin heavy chain (chc1) temperature-sensitive alleles, but not with mutations in COPI subunits or other SEC genes tested.

Treatment of acute bacterial diarrhea: a multicenter international trial comparing placebo with fleroxacin given as a single dose or once daily for 3 days.

This study was designed to test the efficacy of 400 mg fleroxacin given orally as a single dose or once daily for 3 days against acute bacterial diarrhea. A group of 508 adults with acute diarrhea were entered into a randomized, double-blind, placebo-controlled, multicenter trial. Patients were examined and asked about numbers of liquid stools daily for 3 days and at 5 days after start of treatment.

Oral ciprofloxacin vs parenteral cefotaxime in the treatment of difficult skin and skin structure infections. A multicenter trial.

A prospective, randomized, double-blind, multicenter study was conducted of hospitalized patients to compare the efficacy and safety of oral ciprofloxacin (dosage, 750 mg every 12 hours) with intravenous cefotaxime (dosage, 2.0 g every 8 hours) as monotherapy for difficult skin and skin structure infections requiring hospitalization. Five hundred seventy patients were assessed for an analysis of safety and 461 patients were assessed for an analysis of efficacy.

A comparative study of the efficacy and safety of azlocillin and gentamicin in the treatment of serious infections.

Azlocillin, a new semisynthetic ureidopenicillin, has increased in-vitro activity against Pseudomonas aeruginosa and good activity against other Gram-negative organisms. In a comparative clinical study, azlocillin was administered intravenously at 18 g/day to 24 patients and gentamicin intramuscularly at 3 to 5 mg/kg/day to 25 patients, most of whom had infections of the skin and skin structure, intra-abdominal cavity, or lower respiratory tract. Gram-negative organisms, usually Ps.
