background: the purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (ios) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases.   methods: the study was performed prospectively in 100 patients, who complained of dyspnea a...

developed in 1991, nucleic acid sequence-based amplification (nasba) has been introduced as a rapid molecular diagnostic technique, where it has been shown to give quicker results than pcr, and it can also be more sensitive. this paper describes the development of a molecular beacon-based multiplex nasba assay for simultaneous detection of hiv-1 and hcv in plasma samples.a well-conserved region...

conclusions despite rapidity, automation, accuracy, cost-effectiveness, high sensitivity, and high specificity of molecular techniques, each type of molecular technology has its own advantages and disadvantages. results various types of molecular biology tools can be used to detect and quantify viral genomic elements and analyze the sequences. these molecular assays are proper technologies for ...

background and objective: celiac disease is an autoimmune disorder, characterized by inflammation, villous atrophy, and crypt hyperplasia of the small bowel mucosa. in this study we considered and compared sensitivity and specificity of serological tests in patients with celiac disease. materials and methods: in this cross-sectional study we prospectively recruited children with suspected celia...

introduction: patients with cystic fibrosis have increased risk of malnutrition. early detection of nutritional deterioration enables prompt intervention and correction. the aims of this project were to: - define the nutritional status of cf patients in iran and new zealand -    compare and contrast the macdonald nutritional screening tool  with the australasian guidelines for nutrition in cyst...

cystoscopy and urinary cytology are currently the basis for diagnosis and ‎follow-up of bladder tumors. research to find a sensitive and specific tumor ‎marker for diagnosis of bladder tumor is actively underway, however, due to low sensitivity ‎and high cost of cytology. this cross-sectional study was performed in 65 patients to evaluate whether urinary bladder ‎cancer (ubc) antigen level can ...
