Abstract Funding Acknowledgements Type of funding sources: None. Background The electrophysiological inducibility atrial fibrillation (AF) after pulmonary vein isolation (PVI) has been identified as a predictor future AF recurrence. Stimulation protocols have not sufficiently studied prospectively with respect to their reliability for inducing AF. Methods and results We conducted prospective mo...
Background and Aim: Brucellosis is a zoonotic disease and is one of the major health problems in our country. Considering its nonspecific symptoms, diagnosis of this disease is often made by laboratory methods. The purpose of the present study was to compare the sensitivity and specificity of ELISA and a relatively new modified Rose Bengal test in the diagnosis of brucellosis. Material and Meth...
This study aimed to evaluate the diagnostic performance of different imaging techniques for preoperative detection pelvic fistula. Imaging and classification female genital abnormalities considerably floor fistulas are significant. We conducted a systematic review available literature highlight effectiveness radiological (X-RAY,U/S,CT,MRI) diagnosis types see limitations conventional scanning t...
The objective of this study was to compare an indirect ELISA, based on a purified 60 kDa envelope glycoprotein (gp51SU), with a Pourquire indirect ELISA for the detection of antibodies to the bovine leukemia virus. For conducting this research, 340 serum samples were collected from two different breeds of cows (Sarabi and Holestin) in different herds. Commercial ELISA revealed positive results ...
Background: Brucellosis is one of the important zoonotic diseases with variety of symptoms and signs. Using of cost effective, easy and safe diagnostic methods in screening of brucellosis is an important priority. Several studies have been carried out to recognize appropriate diagnostic methods and each have reported different results. Aim: The aim of this study was to investigate the sensitivi...
Introduction: [64Cu]diacetyl-bis(N4-methylthiosemicarbazone) ([64Cu]ATSM) is a well-established hypoxia imaging tracer with reproducible production and significant specifity. In this work the high yield production and quality control as well as imaging studies in healthy rabbits is reported. Methods: Copper-64 produced ...
Introduction: [61Cu]diacetyl-bis(N4-methylthiosemicarbazone) ([61Cu]ATSM) is a well-established hypoxia imaging tracer with simple production and significant specifity. In this work the accumulation of the tracer is studied in wild-type, necrotic and hypoxic fibrosarcoma tumors. Methods: [61Cu]ATSM was prepared u...
Abstract Background and objectives: With almost nine million new cases each year, tuberculosis is still one of the most Life-threatening diseases in the World. Distribution of drug resistant strains of M.tuberculosis has a lot of importance. This research was carried out to determine the frequency of drug resistance of M. tuberculosis in strains isolated in Golestan province. Material and...
Background and Objectives: Bacterial meningitis especially meningococcal meningitis is a serious and sometimes fatal infection . The aim of this study was the determination of meningitis disease by routine and molecular assay s . Materials and Methods : CSF samples were collected from 275 children and agglutination, bacteriological tests were achieved. DNA extraction was done according to p...
A sensitive and reproducible enzyme-linked immunosorbent assay (ELISA) is described for the detection of immunoglobulin M and antibodies with specifity for human cytomegalovirus (CMV) early (CMV-EA) and late (CMV-LA) antigens. The emphasis is on the production of high-quality CMV antigens, CMV-EA and CMV-LA separately, and conditions for their application in the ELISA. The induction of CMV-EA a...
