The dump, with the compact rock platform and high steep loose slope that is formed during coal mining, most serious area of soil erosion in a surface mine. Ground fissures are typical geological hazard mining areas. However, effect ground on remains unclear. Rainfall experiments were conducted to determine varying characteristics wetting front, runoff sediment production, denudation rate, as we...
Standard hand and foot roentgenograms from 200 consecutively hospitalised patients with definite or classical rheumatoid arthritis (RA) were read for marginal erosions by three independent observers. For each joint or group of joints analysed the degree of symmetry (S = absolute symmetry, U = unilateral, PS = partial symmetry) was determined. The total number of joints affected significantly co...
BACKGROUND To analyze risk factors associated with gastro-duodenal ulcers and erosions in children. METHODS Open, prospective, multicenter, case-control study carried out in 11 European countries in patients with gastric or duodenal ulcers/erosions and 2 age-matched controls each. Possible risk factors were recorded. Logistic regression models were performed with adjustment for centers and ag...
BACKGROUND Proton pump inhibitor and histamine-2 receptor antagonist can prevent aspirin-related ulcers/erosions but few studies compare the efficacy of these two agents. Aims. We evaluated the efficacy of omeprazole and famotidine in preventing recurrent ulcers/erosions in low-dose aspirin users. METHODS The 24-week clinical outcomes of the patients using low-dose aspirin for cardiovascular ...
OBJECTIVE To develop a precise three-dimensional (3D) segmentation technique for bone erosions in high-resolution peripheral quantitative CT (HR-pQCT) datasets to measure their volume, surface area and shape parameters. Assessment of bone erosions in patients with RA is important for diagnosis and evaluation of treatment efficacy. HR-pQCT allows quantifying periarticular bone loss in arthritis....
the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
BACKGROUND Dental erosions are determined by a mechanism involving increased oral acidity. Gastro-esophageal reflux disease (GERD) represents the pathological reflux of gastric content into the oral cavity, affecting the hard dental tissues integrity, with a major risk of advanced tooth wear. AIM This study aims to investigate the prevalence of dental erosions in GERD patients, in order to ob...
To cite: Toescu SM, Kennon S, Stevens H. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013201536 DESCRIPTION A 64-year-old man presented with a 12-month history of angina. Following coronary angiography he underwent percutaneous coronary intervention with deployment of drug-eluting stents to the left anterior descending and main diagonal branch. He was discharg...
