Background: The causality role of different immune phenotype in IR developing among Chronic Heart Failure (CHF) subjects has not determined obviously. The aim of the study was to assess relationship between IR and immune phenotype of circulating endothelial-derived microparticles (EMPs) in patients with CHF. Methods: The study retrospectively involved 300 CHF patients aged 48 to 62 years who we...

Microparticle (MP) research is clouded by debate regarding the accuracy and validity of flow cytometry (FCM) as an analytical methodology, as it is influenced by many variables including the pre-analytical conditions, instruments physical capabilities and detection parameters. This study utilises a simplistic in vitro system for generating MP, and through comparative analysis with immuno-electr...

introduction: a noninvasive method of detecting exposure of phosphatidylserine (ps) on the external surface of the plasma membrane such as nuclear imaging could assist the diagnosis and therapy of apoptosis related pathologies. the most studied imaging agent for apoptosis is annexin v so far. because of limitations of annexin v other agents have been introduced such as small peptides and molecu...

UNLABELLED Although apoptosis within atherosclerotic plaques is associated with plaque vulnerability and rupture, the role of inhibition of the apoptotic process is not clear. We evaluated the impact of dietary modification and statin therapy (measures known to favorably influence outcomes in coronary disease) on the incidence of apoptosis in experimental atherosclerotic lesions. METHODS A to...

OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

Liposomes (phospholipid vesicles) have been proposed as carriers of materials of therapeutic interest, and work in this area has been reviewed (Tyrrell et al., 1976). The possibility of utilizing such a system in tumour therapy has received some attention, and Gregoriadis et al. (1974) injected patients with liposomes using entrapped l3II labelled albumin as a marker. Tissue distribution was me...

This study aimed to prepare a novel radiopharmaceutical for the detection of brain disorders at early stages in susceptible patients.Promazine hydrochloride was labeled with 125I by direct electrophilic substitution reaction high labeling yields 92.6 ± 3.24 %. The yield and vitro stability 125I-promazine were determined paper electrophoresis, chromatography (PC) High performance liquid (HPLC). ...
