in this research, the thin films of n-s doped titanium dioxide (tio2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. furthermore, titanium dioxide (tio2) was functionalized with thiourea. furthermore, n-s doped titanium dioxides (nsto) were fixed on glass balls by glass balls fixed-bed reactor system. besides, the effect of ...
Toxoplasma gondii matrix antigen 1 (TgMAG1), known as the 65-kDa protein, which is abundantly expressed in both bradyzoites and tachyzoites, was evaluated as a candidate for the development of a diagnostic reagent for ovine toxoplasmosis. The TgMAG1 gene was expressed in Escherichia coli as a fusion protein with glutathione S-transferase (GST), and the recombinant TgMAG1 (rTgMAG1) was tested in...
For the rapid and simple diagnosis of schistosomiasis, a reagent strip assay for detection of circulating cathodic antigen (CCA) in urine was developed. The test was based on a previously developed sandwich enzyme-linked immunosorbent assay (ELISA) using a combination of two anti-CCA monoclonal antibodies. For the reagent strip assay, as the capture matrix, monoclonal antibody was coated onto a...
Experimental Section Materials. N-Isopropylacrylamide (NIPAM, 97%, Tokyo Kasei Kagyo Co.) was purified by recrystallization from a mixture of benzene and n-hexane (1/3, v/v). Styrene (St, 99.5%, Beijing Chemical Factory) was successively washed with aqueous NaOH (5.0 wt %) and water, then distilled over CaH 2 at reduced pressure. 4-Chloro-7-nitrobenzofurazan (NBD-Cl, 99%), 2,3,3-trimethylindole...
this study was aimed to evaluate the efficacy of dipstick tests (leukocyte esterase and nitrite) in diagnosis of spontaneous bacterial peritonitis (sbp) in cirrhotic patients. forty six children with ascites hospitalized between 2009 and 2010 in children medical center were enrolled in this study. reagent strip assays for leukocyte esterase and nitrite were performed on ascetic fluid and the re...
Intra-erythrocytic concentration of 2,3-diphosphoglycerate is a major determinant of the oxygen affinity of hemoglobin. We report here the adaptation of its assay to a centrifugal analyzer, with use of a commercially available reagent. Results are calculated by using the reagent-blank-corrected absorbance change at 340 nm between 120 and 300 s for the samples and a 2.5 mmol/L standard. Under th...
The experimental conditions of the sample delivery inside the reagent-release capillary-based capillary-assembled microchip (RRC-based CAs-CHIP) were optimized and the reagent release procedure in the RRC is discussed. Recently, our group introduced the basic concept of the "drop-and-sip" fluid handling technique (Anal. Chem., 2007, 79, 908). A microliter volume of sample solution is dropped on...
An intervention study was conducted in Khamir, north of Sana'a, for control of urinary schistosomiasis using chemotherapy and health education. The validity and cost-effectiveness of reagent strips as a rapid diagnostic tool to screen for Schistosoma haematobium infection was also assessed along with visible haematuria. Prevalence of S. haematobium infection 14 months post-intervention fell fro...
