Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...
The main objective of a meteorological nowcasting system is to analyse and predict in ultra-short range those weather phenomena, which might be dangerous for life and property. The Hungarian Meteorological Service developed a nowcasting system (MEANDER), and its most computational intensive calculations have been parallelised by means of P-GRADE graphical programming environment. In this paper ...
AIMS To compare the expression of the cell adhesion molecules P-cadherin, N-cadherin, and E-cadherin in invasive and in situ breast carcinomas relative to clinicopathological features (size, node status, type, grade, and receptors) to determine whether expression patterns relate to specific tumour characteristics. METHODS Using immunohistochemistry, 110 invasive and in situ breast carcinomas ...
This study aimed to investigate whether pulmonary shunt grade on transthoracic contrast echocardiography (TTCE) predicts the size of pulmonary arteriovenous malformations (PAVMs) on chest computed tomography (CT) and subsequent feasibility for transcatheter embolotherapy. We prospectively included 772 persons with possible or definite hereditary haemorrhagic telangiectasia, who underwent both T...
High-grade extracellular vesicles preparation by combined size-exclusion and affinity chromatography
Abstract Extracellular vesicles (EVs) have recently gained growing interest for their diagnostic and therapeutic potential. Despite this, few protocols been reported the isolation of EVs with preserved biological function. Most EV purification methods include a precipitation step that results in aggregation most available techniques do not efficiently separate various types such as exosomes ect...
Background and objectives: Osteoporosis, a current silent epidemic, is of high importance due to its high prevalence and complications among women. It is a preventable disease whose high-risk population includes young girls. This study investigated the impacts of a health belief model-based education program about osteoporosis prevention on physical activity of junior high school students in in...
background: ischemic heart disease (ihd) is the main cause of morbidity and mortality worldwide, and a considerable part of these patients attend to emergency departments, which increases the burden to these busy departments. the aim of this study was to develop a prediction model enabling prediction of all cause emergency department (ed) visits in patients with documented coronary stenosis in ...
