aim : to evaluate the diagnostic value of helicobacter pylori stool antigen test before and after eradication background : there are different methods for diagnosis and follow up of helicobacter pylori infection, including invasive methods done with endoscopy and non invasive ones such as ubt and urine analysis antibody. one of non invasive new methods is analysis of helicobacter pylori stool a...
the aim of this study was to compare invasive and non-invasive strains of shigella flexneri isolated from tehran by a 120 kda protein band by sds-page, electron microscopy of cell culture and congo red dye methods. methods: s. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. phenotype analysis for screening vi...
objective: the risk of cardiac death in diabetic patients is 3 times more than non-diabetics. but it is not determined who need cardiac screening. about 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (cimt) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.the aim of ...
Objectives We developed a simple non-invasive I-123-N-isopropyl-p-iodoamphetamine (123I-IMP) quantification method by analyzing chest RI-angiography and single photon emission computed tomography (SPECT) images based on the microsphere model (SIMS method). Theoretically, the SIMS method could be changed to the simple non-invasive ARG (SIARG) method by modifying the integrated washout ratio (WR)...
AIMS Left ventricular (LV) pressure-strain loop area reflects regional myocardial work and metabolic demand, but the clinical use of this index is limited by the need for invasive pressure. In this study, we introduce a non-invasive method to measure LV pressure-strain loop area. METHODS AND RESULTS Left ventricular pressure was estimated by utilizing the profile of an empiric, normalized ref...
Background & Aim: Tumour angiogenesis is essential for tumour growth and appears to play an important role both in invasive growth and metastasis. Basal cell carcinomas(BCCs) and squamous cell carcinomas(SCCs) of the skin are derived from a similar cell type but differ in the invasive and metastatic potential. This study investigates whether the behaviour of these tumours could be explained...
