PURPOSE The purpose of this study is to determine structural bony abnormalities predisposing for femoroacetabular impingement by comparison of patients with and without mechanical symptoms. MATERIALS AND METHODS We conducted this comparative study on 151 patients (151 hips; mean age 44.8 years; range 16-73 years) with mechanical symptoms with results of multi-detector computed tomography (MDC...

INTRODUCTION Morbidity and mortality conferences (M+M) are a traditional part of residency training and mandated by the Accreditation Counsel of Graduate Medical Education. This study's objective was to determine the goals, structure, and the prevalence of practices that foster strong safety cultures in the M+Ms of U.S. emergency medicine (EM) residency programs. METHODS The authors conducted...

BACKGROUND Obstetric hemorrhage has been repeatedly implicated as a leading cause of maternal mortality in Nigeria, yet there are very few studies that evaluate the practice of blood transfusion in obstetrics as a life saving measure. OBJECTIVES The aim of this study was to evaluate the practice of obstetric blood transfusion, the mean decision-transfusion interval, and the outcome in parturi...

Hepatitis B e antigen (HBeAg) is a secreted version of hepatitis B virus (HBV) core protein that promotes immune tolerance and persistent infection. It is derived from a translation product of the precore/core gene by two proteolytic cleavage events: removal of the amino-terminal signal peptide and removal of the carboxyl-terminal arginine-rich sequence. Four RXXR motifs are present at the carb...

The σ -convergence and σ -core of a real bounded sequence were introduced in [R. Raimi, Invariant means and invariant matrix methods of summability, Duke Math. J. 30 (1963) 81–94] and [S.L. Mishra, B. Satapathy, N. Rath, Invariant means and σ -core, J. Indian Math. Soc. 60 (1984) 151–158], respectively. In this work, we extend these ideas to double sequences. c © 2006 Elsevier Ltd.
