In the present study, toxicity was developed by oral administration of AFB1 at a dose of (2μg/kg body weight) for 45 days in male mice. Curcuma longa (100 and 200 mg/kg body weight) and Curcumin (50 and 100 mg/kg body weight) were given individually and in combination with AFB1 for 45 days. At the end of 45 days, the blood samples were collected from various groups by heart puncture in eppendro...

the 60 apparently common carp, cyprinus carpio (mean weight 700g.) divided to two groups (1:control and 2: test) and transferred to 1000 liter indoor fiberglass tanks supplied with static well water, continuous aeration and defined water quality. test group was exposed to 30ppb (low concentration) cadmium as cdcl 2 (merck) control group was without cadmium addition . blood samples were caught r...

A variety of statistical methods have been suggested for detecting differential item functioning (DIF) in the Rasch model. Most of these methods are designed for the comparison of pre-specified focal and reference groups, such as males and females. Latent class approaches, on the other hand, allow the detection of previously unknown groups exhibiting DIF. However, this approach provides no stra...

This article presents a meta-analysis of studies investigating the effectiveness of the Mantel-Haenszel (MH) procedure when used to detect differential item functioning (DIF). Studies were located electronically in the main databases, representing the codification of 3,774 different simulation conditions, 1,865 related to Type I error and 1,909 to statistical power. The homogeneity of effect-si...

BACKGROUND N-Formyl-methionyl-leucyl-phenylalanine (FMLP) is a bacterial oligopeptide which stimulates neutrophil chemotaxis, degranulation and superoxide generation. Inhalation of FMLP produces bronchoconstriction in man; in the rabbit this is in part neutrophil dependent. The effects of inhalation of FMLP on peripheral blood leucocytes in normal subjects has been studied. METHODS This was a...
