BackgroundWe evaluated the long-term outcomes of coronary artery bypass grafting (CABG) according to β-blocker therapy using landmark analysis. Although β-blockers have been shown improve for ischemic heart disease, effects and optimal treatment duration use after CABG remain unknown.MethodsFrom January 2001 December 2014, 5382 patients were stratified into 2 groups at discharge (β-blocker grou...

Aim: Single-strap bags cause asymmetric load-carrying and postural asymmetry. This study aimed to investigate the effects of a single-strap bag on peak vertical ground reaction forces (PVGRFs) and on postural stability when it is worn in different positions. Methods: 6 volunteer women were assessed in the Human Movement Laboratory. Force platforms were used to measure both the ground reaction f...

Molecular dynamics simulation of the hydrated dimyristoylphosphatidylcholine (DMPC) bilayer membrane in the liquid-crystalline phase was carried out for 5 ns to study the interaction among DMPC headgroups in the membrane/water interface region. The phosphatidylcholine headgroup contains a positively charged choline group and negatively charged phosphate and carbonyl groups, although it is a neu...

3677 Scholte-Stoneley waves (SSW) propagate at the interface of a fluid medium and a solid medium. They have a velocity smaller than the transverse and longitudinal velocities in the solid, and smaller than the sound velocity in the fluid. They are thus doubly evanescent and propagate without loss along the interface. They were observed for periodically corrugated surfaces in contact with water...

OBJECTIVE To determine whether exposure to allopurinol is associated with an increased risk of cataract extraction in elderly patients. METHODS We conducted a case-control study using data from the Quebec universal health insurance program for all elderly patients. The 3677 cases were patients with a cataract extraction between 1992 and 1994. The 21,868 controls were randomly selected among p...

Libraries as Dysfunctional Organizations and Workplaces documents the widespread evidence that library workers in North America are unhappy with libraries where they work. Although term dysfunction can make book appear to be geared toward managers an interest alleviating those elements of workplace, will appeal anyone working or adjacent LIS field.

BACKGROUND Epidemiologic studies of the prevalence of rheumatic heart disease have used clinical screening with echocardiographic confirmation of suspected cases. We hypothesized that echocardiographic screening of all surveyed children would show a significantly higher prevalence of rheumatic heart disease. METHODS Randomly selected schoolchildren from 6 through 17 years of age in Cambodia a...
