BACKGROUND & OBJECTIVES Rheumatic fever (RF)/rheumatic heart disease (RHD) caused by Group A streptococcus (GAS) are more prevalent in north India as compared to the western world, where invasive diseases are common. This could be due to variation in the virulence of GAS in different geographic locations. Hence, we studied the virulence potential of GAS isolated from the throat of children from...

BACKGROUND Streptococcus dysgalactiae subspecies equisimilis (SDSE) is an emerging global pathogen that can colonize and infect humans. Although most SDSE isolates possess the Lancefield group G carbohydrate, a significant minority have the group C carbohydrate. Isolates are further sub-typed on the basis of differences within the emm gene. To gain a better understanding of their molecular epid...

Streptococcus pyogenes is responsible for a variety of infectious diseases and immunological complications. In this study, 91 isolates of S. pyogenes recovered from oropharynx secretions were submitted to antimicrobial susceptibility testing, emm typing and pulsed-field gel electrophoresis (PFGE) analysis. All isolates were susceptible to ceftriaxone, levofloxacin, penicillin G and vancomycin. ...

One of the significant engineering applications of the elastic metamaterial (EMM) is for low-frequency vibration attenuation because of its unusual low-frequency bandgap behavior. However, the forbidden gap from many existing EMMs is usually of narrow bandwidth which limits their practical engineering applications. In this paper, a chirallattice-based EMM beamwith multiple embedded local resona...

The dismal outcome of pleuropericardial extramedullary multiple myeloma (EMM) reflects both the selection of resistant disease and absence of useful drugs. Carfilzomib and dexamethasone should be explored in advanced EMM patients, even for bortezomib-resistant patients, as may provide much longer overall survival than previously reported treatments.

BACKGROUND Intramyocardial cell injections in the context of cardiac regenerative therapy can currently be performed using electromechanical mapping (EMM) provided by the NOGA®XP catheter injection system. The gold standard technique to determine infarct size and location, however, is late gadolinium enhanced magnetic resonance imaging (LGE-MRI). In this article we describe a practical and accu...

The E-Learning Maturity Model (eMM) is a quality improvement framework designed to help institutional leaders assess their institution's e-learning maturity. This paper reviews the eMM, drawing on examples of assessments conducted in New Zealand, Australia, the UK and the USA to show how it helps institutional leaders assess and compare their institution's capability to sustainably develop, dep...

The incidence of invasive group A streptococcal disease has increased in Norway since the 1980s. Analysis of 100 isolates recovered from 1988 to 2003 showed an increased genotypic diversity over time, while the prevalence of the strain that dominated in 1988, sequence type (ST)-28/emm-1, decreased. Necrotizing fasciitis was often associated with ST-15/emm-3.

This paper establishes the Black Scholes formula in the martingale, risk-neutral valuation framework. The intent is two-fold. One, to serve as an introduction to expectation pricing and two, to examine this framework in explicit mathematical detail. The reader is assumed to have fluent background in the mathematical theory of stochastic processes and calculus, but is not assumed to have backgro...

BACKGROUND Accurate data on costs attributable to hospital-acquired infections are needed to determine their economic impact and the cost-benefit of potential preventive strategies. OBJECTIVE To determine the attributable costs of surgical site infection (SSI) and endometritis (EMM) after cesarean section by means of 2 different methods. DESIGN Retrospective cohort. SETTING Barnes-Jewish ...
