Proteolysis is essential for the execution of many cellular functions. These include removal of incorrectly folded or damaged proteins, the activation of transcription factors, the ordered degradation of proteins involved in cell cycle control, and the generation of peptides destined for presentation by class I molecules of the major histocompatibility(More)
BACKGROUND During the reproductive years, women have a 4-fold higher prevalence of gallstones than men, making gallbladder disease a critically important topic in women's health. Among age-matched women and men hospitalized for cholecystitis, gender based differences in demographics, management, and economic and clinical outcomes were identified. METHODS(More)
The proteasome is a multicatalytic protease complex that plays a key role in diverse cellular functions. The peptide vinyl sulfone, carboxybenzyl-leucyl-leucyl-leucine vinyl sulfone (Z-L3VS) covalently inhibits the trypsin-like, chymotrypsin-like and, unlike lactacystin, also the peptidylglutamyl peptidase activity in isolated proteasomes, and blocks their(More)
BACKGROUND The proteasome is a multicatalytic protease complex responsible for most cytosolic protein breakdown. The complex has several distinct proteolytic activities that are defined by the preference of each for the carboxyterminal (P1) amino acid residue. Although mutational studies in yeast have begun to define substrate specificities of individual(More)
The treatment of isolated sternal fractures (ISF) throughout the world is heterogeneous. This study aimed to identify the incidence, morbidity, and mortality associated with isolated fractures of the sternum and describe current practice for diagnosis and management of ISF and cardiac injury at a level I trauma center in the UK. A retrospective cohort study(More)
Introduction. The aim of this study was to characterize national trends in adoption of laparoscopic cholecystectomy and determine differences in outcome based on type of surgery and patient age. Methods. Retrospective cross-sectional study of patients undergoing cholecystectomy. Trends in open versus laparoscopic cholecystectomy by age group and year were(More)
BACKGROUND Pressure drift (PD), resulting from differences between room and body temperature, reduces the accuracy of pressure measurements with the Manoscan high resolution manometry (HRM) system. Our aims were to assess PD during anorectal HRM. METHODS Defined as the residual pressure measured immediately after the catheter was removed, PD was(More)
Introduction. Accessory breast tissue is a rare finding in the general population with an incidence of 1-2%. An even rarer occurrence is accessory breast tissue afflicted with breast carcinoma. We present a brief report discussing diagnosis and management of a patient who presented with primary breast adenocarcinoma in vulval supranumerary tissue. Brief(More)
