To investigate the effects of a single high-load (80% of one repetition maximum [1RM]) set with additional drop sets descending to a low-load (30% 1RM) without recovery intervals on muscle strength, endurance, and size in untrained young men. Nine untrained young men performed dumbbell curls to concentric failure 2-3 days per week for 8 weeks. Each arm was randomly assigned to one of the following three conditions: 3 sets of high-load (HL, 80% 1RM) resistance exercise, 3 sets of low-load [LL, 30% 1RM] resistance exercise, and a single high-load (SDS) set with additional drop sets descending to a low-load...

BACKGROUND: Calcium sulphate (CS) has been used in bone grafting since the 1800s. It has not replaced autograft as the gold standard, however, since its dissolution occurs rapidly in bodily fluids, meaning that the material cannot support long-term bone growth. Here, the polymer poly (ether ether ketone) (PEEK) was used to slow dissolution in in vitro physiological environments and augment the mechanical properties of the material. METHODS: PEEK/CS specimens were fabricated by combining powders of PEEK and CS with water, resulting in a hardening paste...

INTRODUCTION: Secondary cuff failure after shoulder replacement is disabling and often requires additional surgery. Increased critical shoulder angle (CSA) has been found in patients with cuff tear compared to normal subjects. The interobserver reliability of the CSA and the relationship between CSA and symptomatic secondary cuff failure after shoulder replacement were investigated. MATERIALS AND METHODS: Nineteen patients with symptomatic cuff failure after anatomic shoulder replacement (mean FU 45 months) were compared to a control group of 29 patients showing no signs of symptomatic cuff failure (mean FU 105...

OBJECTIVE: The severity of central sleep apnoea (CSA), a common comorbidity in patients with chronic heart failure (CHF) and reduced ejection fraction, markedly decreases from the supine to the lateral sleeping position, with no difference between the left and right positions. The mechanisms responsible for this beneficial effect have not yet been elucidated. METHODS: We tested the hypothesis that CSA attenuation in the left lateral position is due, at least in part, to an improvement in cardiac haemodynamics...

Prediction of coronary events remains elusive. Carotid atherosclerosis may be a surrogate for coronary risk, as carotid and coronary diseases occur simultaneously - albeit at times with a weak association - depending on clinical presentation. We investigated carotid and coronary atherosclerosis in men with new-onset unstable coronary artery disease (CAD) presenting with acute ST-segment elevation myocardial infarction (STEMI) vs. long-standing severe chronic stable angina (CSA). Bilateral carotid artery and 3-vessel coronary artery atherosclerosis burdens were measured within 1 month, respectively, by 3D-volumetric carotid magnetic resonance imaging and coronary angiography-derived modified CASS-50 score...

Calcineurin inhibitors (CIs) such as cyclosporine A (CSA) and tacrolimus often cause renal dysfunction, resulting in increased serum creatinine, hyperkalemia, and hyperuricemia. However, the effects of CIs on sodium excretion have not been fully elucidated. We retrospectively evaluated the effects of CI administration on sodium excretion in recipients of allogeneic hematopoietic stem cell transplantation (HSCT). Fifty consecutive recipients each of allogeneic HSCT receiving either CSA or tacrolimus (100 patients in total) with available data for weekly fractional excretion of sodium (FENa) for a 4-week period after transplantation were enrolled in this retrospective analysis...

It has been noted that cyclosporine A (CsA) is an effective drug for membranous nephropathy (MN). Diabetes is a common disease that sometimes causes nephrotic syndrome. We report the case of an 89-year-old woman with type 2 diabetes mellitus who exhibited nephrotic syndrome. Examination of a renal biopsy indicated MN and she was prescribed CsA as monotherapy. Her edema subsided and she achieved partial remission. This is the first report of a patient in diabetic condition with MN having achieved partial remission after CsA monotherapy without steroid therapy...

Metabolic defects are common pathological phenomena following traumatic brain injury (TBI) which contribute to poor prognosis. Brain-derived neurotrophic factor (BDNF) is an important regulator of neuronal survival, development, function, and plasticity. This study was designed to investigate the potential effects of BDNF on TBI-induced metabolic defects and their underlying molecular mechanisms. BDNF was added into cultured neurons to a concentration of 25, 50, and 100 ng/ml, respectively, right after mechanical injury and metabolite levels were analyzed 4 h post injury...

Crude soluble antigen (CSA) produced from Entamoeba histolytica trophozoite is conventionally used for serodiagnosis of invasive amoebiasis. However, high background seropositivities by CSA-assay in endemic areas complicate the interpretation of positive result in clinical settings. Instead, incorporating a second assay which indicates active or recent infection into the routine amoebic serology could possibly complement the limitations of CSA-assay. Hence, the present study aimed to evaluate the diagnostic efficacies of indirect ELISAs using CSA and excretory-secretory antigen (ESA) for serodiagnosis of amoebic liver abscess (ALA)...
