In their paper entitled "Comparison of the PREMIER Cryptococcal Antigen Enzyme Immunoassay and the Latex Agglutination Assay for Detection of Cryptococcal Antigens" (1), Gade et al. compare a new enzyme immunoassay (EIA) for the detection and quantification of circulating capsular polysaccharide antigen from Cryptococcus neoformans with the latex agglutination (LA) test performed with a commerc...

conclusions this investigation revealed that berberis fruit extract has beneficial metabolic effects in patients with type ii diabetes. barberry may improve glucose catabolism via glycolysis pathway, stimulate insulin secretion or improve insulin function and finally decrease glucose uptake. our results indicated that berberis fruit regulates glucose metabolism in patients with type 2 diabetes....

PURPOSE Resistance is commonly acquired in patients with metastatic gastrointestinal stromal tumor who are treated with imatinib mesylate, often due to the development of secondary mutations in the KIT kinase domain. We sought to investigate the efficacy of second-line tyrosine kinase inhibitors, such as sorafenib, dasatinib, and nilotinib, against the commonly observed imatinib-resistant KIT m...

BACKGROUND The diagnosis of PPL (major determinant) and MDM (minor determinant) sensitization as relevant allergens in beta-lactam allergy has been recently hampered by withdrawal from the market of formerly available test kits. We investigated a new PPL/MDM test kit in the work-up of beta-lactam allergy. PATIENTS AND METHODS 15 patients with history of beta-lactam allergy were investigated f...

in a comparative study, 460 serum samples were tested for the serological determination of human immunodeficiency vrius (hiv) using an elisa kit and a rapid test kit. results indicated that the rapid test is reliable for screening unkonwn samples when there is no special equipment for screening with immunoblotting and/or elisa.

To the Editor: We read with interest the article entitled ‘‘A Missense Mutation in KIT Kinase Domain 1 Correlates with Imatinib Resistance in Gastrointestinal Stromal Tumors’’ by Chen et al. because we have recently found the same mutation in a one of our surgically treated gastrointestinal stromal tumor patients. This patient had a metastatic gastrointestinal stromal tumor carrying a KIT exon ...

A directory of test patterns and their interpretations has been prepared for identification of Enterobacteriaceae by using the 11-test API 10 S kit. The diagnostic accuracy of the directory and kit were evaluated by using records of test results for 37,476 isolates studied with the 21-test API 20 Enteric kit. Analysis indicates that 96.9% of the isolates would have been correctly identified at ...

conclusions the homemade kit, compared with the imported kit and biopsy-proven tests may be a valid and reliable method for determining the presence of h. pylori infection in iran. background current diagnosis of helicobacter pylori infection by biopsy-based tests requires invasive sampling. non-invasive methods such as the h. pylori stool-antigen (hpsa) test may be the best alternative for dia...
