A multicenter clinical trial conducted by the authors compared the desensitizing efficacy of a new 5 percent potassium nitrate: 0.243 percent sodium fluoride dentifrice along with two clinically proven, commercially available desensitizing dentifrices to a placebo dentifrice. Sensitivity to cold air and tactile stimulation, along with patients' subjective(More)
We assessed the penetration of a new carbapenem antibiotic, meropenem, into abdominal tissues. A single 1,000-mg intravenous dose was administered to 66 patients undergoing elective intraabdominal surgery. Plasma, body fluid (peritoneal fluid and bile), and tissue samples (colon, gallbladder, omentum, stomach, fascia, muscle, and skin) were taken at various(More)
The Lowe syndrome (LS) is a life-threatening, developmental disease characterized by mental retardation, cataracts and renal failure. Although this human illness has been linked to defective function of the phosphatidylinositol 5-phosphatase, Ocrl1 (Oculo-Cerebro-Renal syndrome of Lowe protein 1), the mechanism by which this enzyme deficiency triggers the(More)
Sorting of transmembrane proteins to various intracellular compartments depends on specific signals present within their cytosolic domains. Among these sorting signals, the tyrosine-based motif (YXXØ) is one of the best characterized and is recognized by μ-subunits of the four clathrin-associated adaptor complexes (AP-1 to AP-4). Despite their overlap in(More)
The objectives of this prospective single-blind trial were to compare the efficacy and safety of cefadroxil, 1 gm/day, and cephalexin, 250 mg four times a day, in the treatment of facial cellulitis of odontogenic origin. One hundred sixteen patients were screened for sensitivity to the assigned antibiotic and then randomly assigned treatment groups.(More)
The in vitro activity of fleroxacin was determined by broth microdilution against 2,079 recent bacterial isolates and compared to the activities of ciprofloxacin, ofloxacin, lomefloxacin, cefaclor, cefuroxime, cefixime, ceftriaxone, amoxicillin/clavulanate, trimethoprim/sulfamethoxazole (TMP-SMX), and, as appropriate, erythromycin and oxacillin.
