Two novel series of quinoxalines derived from 3-phenylquinoxalin-2(1H)-one and 2-hydrazino-3-phenylquinoxaline, namely 1-substituted-3-phenylquinoxaline-2(1H)-ones, 2a-c, 3a-d, and 4; 2-(3-oxo-3,3a,4,5,6,7-hexahydroindazol-2-yl)-3-phenylquinoxaline 6; N- cyclopentylidene or benzylidene-N'-(3-phenylquinoxaline-2-yl)hydrazines, 7 and 18;(More)
A new vancomycin (VCM)-eluting mixed bilayer niosome formulation was evaluated for the control of staphylococcal colonization and biofilm formation on abiotic surfaces, a niosome application not explored to date. Cosurfactant niosomes were prepared using a Span 60/Tween 40/cholesterol blend (1: 1: 2). Tween 40, a polyethoxylated amphiphile, was included to(More)
HCV is a single-stranded RNA virus with a single open reading frame (ORF) that is translated into a polyprotein that is then processed to form 10 viral proteins. An additional eleventh viral protein, the alternative reading frame protein (ARFP), was discovered relatively recently. This protein results from a translational frameshift in the core region(More)
Methicillin resistance among staphylococci isolated from patients in northern Egypt has escalated alarmingly in the past decade. Data about the prevalence of fusidic acid (FA) resistance in Egyptian clinical isolates are limited. This work investigates the prevalence and mechanism of FA resistance among 81 methicillin-resistant staphylococcal isolates from(More)
Microbial contamination of pharmaceuticals poses a great problem to the pharmaceutical manufacturing process, especially from a medical as well as an economic point of view. Depending upon the product and its intended use, the identification of isolates should not merely be limited to the United States Pharmacopeia (USP) indicator organisms. Eighty-five(More)
