Background & Aims: Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease worldwide. The clearance of the HCV is dependent on cytokines control led by genetic. The purpose of this study was to investigate the impact of Lymphotoxin (LT-A) polymorphism at +252 in susceptibility to chronic hepatitis C. Methods: In this case-control study, 120 individuals infected by HCV and ...

We study the topological structure of the SU(2) vacuum at zero temperature: topological susceptibility, size, shape and distance distributions of the instantons. We use a cooling algorithm based on an improved action with scale invariant instanton solutions. This algorithm needs no monitoring or calibration, has an inherent cut off for dislocations and leaves unchanged instantons at physical sc...

Introduction Recently great interest has been devoted to the tissue contrast observed in phase images, not only in veins and iron rich regions (1) but also contrast between WM and cortical GM (2). The tissue phase variations are thought to originate from either tissue susceptibility variations (3) or variations of macromolecules content affecting the water chemical shift (4). The two mechanisms...

conclusions the emergence of streptococcus pneumoniae strains with multiple resistance needs permanent monitoring of antibiotic susceptibility patterns of clinical isolates. we have found that ceftazidime is not a suitable drug for choosing the treatment of pneumococcal infections. results the study showed that three strains (6%) and six strains (12%) indicated intermediate resistance and compl...

objectives: staphylococcus aureus is an important cause of serious infection in both hospital and the community. methicillin-resistant s. aureus (mrsa) is associated with high morbidity and mortality rates with rapid development of resistance. there is a need for early and reliable detection of mrsa infection to direct antibiotic therapy, and more effectively control cross-infection. in this st...

Introduction: Quantitative Susceptibility Mapping (QSM) provides both visualization and quantification of endogenous and exogenous susceptibility contrast. Finding the susceptibility distribution from the measured field map requires a deconvolution of that field map with the unit dipole response, a process which is ill-posed [1]. Several techniques have been proposed to solve the problem by mul...

Quantitative susceptibility mapping (QSM) has only recently entered the ever increasing armamentarium of magnetic resonance imaging. It represent a novel quantitative contrast of an intrinsic physical tissue property that may be regarded as one of the most fundamental properties in the context of magnetic resonance imaging because it reflects the reaction of the tissue to the static main magnet...
