حرکت سریع رسوبات، می تواند منجر به جریان های بسیار مخرب و گذرا در محیط های رودخانه ای و ساحلی ناشی شود که بسیاری از مسائل ژئومورفولوژی و مهندسی با آن مواجه می شوند. شکست سد بر بستر فرسایش پذیر، زمین لغزش زیر دریا، ریزش دیواره رودخانه ها و خروج رسوبات از مخازن تنها چند نمونه از این مسائل هستند. پیش بینی دقیق پیچیدگی ها در سیستم آب -رسوب (یک سیستم جریان دانه ای متراکم چند فازی) هنوز یک چالش عمده ...
BACKGROUND The goal of this study was to assess the clinical value of stress myocardial perfusion scintigraphy (MPS) in elderly patients (> or =75 years of age). METHODS AND RESULTS We followed up 5200 elderly patients (41% exercise) after dual-isotope MPS over 2.8+/-1.7 years (362 cardiac deaths [CDs], 7.0%, 2.6%/y) and a subset with extended follow-up (684 patients for 6.2+/-2.9 years; 320 ...
OBJECTIVES Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease characterised by synovitis and joint destruction. The pathogenesis of RA is not clear, but is considered to be an immune-mediated inflammatory disorder, in which the complement system plays an important role. Although cell-derived microparticles (MPs) have been associated with inflammation and complement activation,...
BACKGROUND Many rare diseases of childhood are life-threatening and chronically debilitating, so living with a rare disease is an on-going challenge for patients and their families. MPS is one of a range of rare inherited metabolic disorders (IMDs) that come under category 3 of life-limiting conditions, where there is no curative treatment available at present. Although the study of rare diseas...
BACKGROUND Mesoporous silica (MPS) nanoparticles (NPs), which have a unique pore structure and extremely large surface area and pore volume, have received much attention because of their biomedical application potential. Using MPS NPs for biomedical devices requires the verification of their biocompatibility because the surface area of NPs is one of the most important determinants of toxicity, ...
After ischaemic injury and in patients with atherosclerosis, the pool of inflammatory macrophages is enlarged in the heart and in atherosclerotic plaques. Monocyte/macrophage-derived microparticles (MPs) are part of the pathological process of unstable atherosclerotic plaques. The present study focused on effects of MPs, produced by apoptotic murine RAW 264.7 macrophage cell line, in adult muri...
AIMS Elevated serum C-reactive protein (CRP) following myocardial infarction (MI) is associated with poor outcomes. Although animal studies have indicated a direct pathogenic role of CRP, the mechanism underlying this remains elusive. Dissociation of pentameric CRP (pCRP) into pro-inflammatory monomers (mCRP) may directly link CRP to inflammation. We investigated whether cellular microparticles...
UNLABELLED Recently, a clinical study on patients with stable coronary artery disease (CAD) showed that external counterpulsation therapy (ECP) at high (300 mmHg) but not at low inflation pressure (80 mmHg) promoted coronary collateral growth, most likely due to shear stress-induced arteriogenesis. The exact molecular mechanisms behind shear stress-induced arteriogenesis are still obscure. We t...
This study aimed to investigate the pharmacology and anti-parasitic efficacy of albendazole-chitosan microspheres (ABZ-CS-MPs) for established intraperitoneal infections of Echinococcus multilocularis metacestodes in an experimental murine model. Male outbred Kunming mice infected with E. multilocularis Metacestodes were administered with three ABZ formulations, namely, ABZ-CS-MPs, Liposome-Alb...
An innovative flow cytometric approach for small-size platelet microparticles: influence of calcium.
Microparticles (MPs) are small submicron membrane-derived vesicles shed from a variety of cells and they have been implicated in different disorders. Accordingly, understanding of physiological characteristics of MPs and improvement of methods of their quantification are important for further advance in the field. Although flow cytometry is the most widely applied technique for MP analysis, it ...
