to prevent post cholecystectomy infection, the most common microorganisms causing it and their antibacterial susceptibility pattern should be determined. therefore, the aim of the present study was to determine the exact incidence and nature of the microbial flora in the bile of the patients with cholelithiasis and chronic cholecystitis as well as their antibiotic sensitivity pattern. in this s...

staphylococcus aureus is a major bacterial pathogen that causes different community- and hospital-acquired infections. over time, strains of s. aureus have become resistant to different antibiotics including penicillinase-resistant penicillins. having data on the local antimicrobial susceptibility pattern of this pathogen is necessary for selection of appropriate antibiotics for empirical treat...

background pseudomonas aeruginosais an opportunistic pathogen which causes severe, acute and chronic nosocomial infections. these infections are difficult to eradicate since the organisms are usually multidrug-resistant. carbapenems are considered as the most effective drugs against these isolates. however, recent emergence of carbapenem-resistant p. aeruginosa has become a major healthcare pro...

Lack of standardization in antibiogram (ABGM) preparation (the overall profile of antimicrobial susceptibility results of a microbial species to a battery of antimicrobial agents) has not been addressed until recently. The objective of this study was to analyze current antibiograms using the recently published NCCLS M39-A guidelines for preparation of antibiograms to identify areas for improvem...

PURPOSE To analyze the correlation of the polymorphisms of human wing-apart like (hWAPL) gene (rs7083506 and rs11202058) with the susceptibility to cervical cancer. Besides, the relationship of haplotypes between the polymorphisms with cervical cancer susceptibility was analyzed. METHODS Taqman probe genotyping method was adopted to detect the genotype distribution of hWAPL rs7083506 and rs11...

In MRI, the main magnetic field polarizes the electron cloud of a molecule, generating a chemical shift for observer protons within the molecule and a magnetic susceptibility inhomogeneity field for observer protons outside the molecule. The number of water protons surrounding a molecule for detecting its magnetic susceptibility is vastly greater than the number of protons within the molecule f...

Candida species are a common cause of nosocomial bloodstream infections. Recent surveillance has shown an increase in the relative proportion of infections caused by Candida glabrata, which has reduced susceptibility to fluconazole. We undertook sentinel surveillance with antifungal susceptibility testing to monitor the trends in the proportions of various Candida species causing invasive disea...

Three-dimensional gradient echo (GRE) is the main workhorse sequence used for susceptibility weighted imaging (SWI), quantitative susceptibility mapping (QSM), and susceptibility tensor imaging (STI). Achieving optimal phase signal-to-noise ratio requires late echo times, thus necessitating a long repetition time (TR). Combined with the large encoding burden of whole-brain coverage with high re...

Cancer incidence varies markedly by ethnicity and geographic location. Ethnic variation in cancer occurrence has traditionally been ascribed to differences in social, cultural, economic, and physical environments. However, this interpretation of the epidemiologic evidence may need to be revised as a result of new biological evidence and theories of carcinogenesis. Carcinogenesis is now recogniz...

Purpose. To test whether the interanimal variability in susceptibility to visually induced myopia is genetically determined. Methods. Monocular deprivation of sharp vision (DSV) was induced in outbred White Leghorn chicks aged 4 days. After 4 days' DSV, myopia susceptibility was quantified by the relative changes in axial length and refraction. Chicks in the extreme tails of the distribution of...
