A latex agglutination (LA) method for detection of pneumococcal antigens was evaluated and compared with counterimmunoelectrophoresis (CIE). LA was 2 to 10 times more sensitive than CIE for the detection of purified capsular polysaccharides in defined media, but only when a 1+ or 2+ agglutination reaction was interpreted as positive. LA was much less sensitive than CIE with clinical samples. In...

This article gives a short overview of the history of the document CIE 220:2016 Characterization and Calibration Method of UV Radiometers (CIE, 2016) and its most important content. In particular, the subject of spectral mismatch is covered. The technical document CIE 220 prepared by CIE Technical Committee TC2-47 describes quality indices for UV radiometers, which enable manufacturers and user...

sheep is one of the important hosts for hydatidosis in iran as a hyperendemic region worldwide. in the present study, the efficacy of counter immuno-electerophoresis (cie) and pcr tests to detect sheep hydatid cyst infection was carried out. for this, soluble antigen was provided using hydatid cyst fluids (hcfs). blood sera were taken from a total number of 100 slaughtered sheep. cie analysis w...

The colour-matching functions of standard observers proposed by the CIE represent the normal colour vision for the worldwide population. But there are deviations in the colourmatching functions for real observers with a normal colour vision, so the observer metamerism index was defined by CIE to evaluate the mismatch between them in colour appearance. In this work, we present an alternative for...

The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a ‎new method is introduced for determining the relationship between spectrophotometric ‎error and colorimetric inaccuracy. The error propagation in colorimetric parameter ‎calculation is evaluated using a linear relation between variance of reflectance spectra ‎and CIE tristimulus values. This linear formula ca...

This study focuses on the preventive effects of aqueous extract of Cichorium intybus (CIE) on streptozotocin (STZ) induced β-cell damage. Pancreatic β-cells or islet were treated with STZ in presence and absence of Cichorium intybus and the inhibitory effect of it against STZ toxicity were determined in RINm5F (RIN) rat insulinoma cells. Cell viability, Nitric oxide production and Insulin secre...

Many clinical laboratories are currently using counterimmunoelectrophoresis (CIE) as an aid in the rapid diagnosis of bacterial meningitis. Because cross-reactions among causative agents have been reported, the present study was undertaken to explore the problems that might occur when reference and commercial antisera are used in CIE. Broth cultures of 35 bacterial strains were tested with 76 r...

A counterimmunoelectrophoresis (CIE) technique which reacted positively with culture filtrates of Clostridium difficile was developed and compared with a cytotoxicity assay in human embryonic lung cell cultures. CIE, employing C. sordellii antitoxin, detected 17 of 17 C. difficile strains. Of those positive by CIE, 13 were cytotoxic in cell culture. Fourteen Clostridium species other than C. di...

The molecular mechanisms and the biological functions of clathrin independent endocytosis (CIE) remain largely elusive. Alix (ALG-2 interacting protein X), has been assigned roles in membrane deformation and fission both in endosomes and at the plasma membrane. Using Alix ko cells, we show for the first time that Alix regulates fluid phase endocytosis and internalization of cargoes entering cel...
