Immunotoxicity evaluation of novel bioactive composites in male mice as promising orthopaedic implants.

Objective: In orthopaedics, novel bioactive composites are largely needed to improve the synthetic achievement of the implants. In this work, semiconducting metal oxides such as SiO, TiO, and ZrO particles (Ps) were used individually and in different ratios to obtain different biphasic composites. The immunotoxicity of these composites was tested to inspect the potential toxicity prior to their use in further medical applications.

Comprehensive growth performance, immune function, plasma biochemistry, gene expressions and cell death morphology responses to a daily corticosterone injection course in broiler chickens.

The massive meat production of broiler chickens make them continuously exposed to potential stressors that stimulate releasing of stress-related hormones like corticosterone (CORT) which is responsible for specific pathways in biological mechanisms and physiological activities. Therefore, this research was conducted to evaluate a wide range of responses related to broiler performance, immune function, plasma biochemistry, related gene expressions and cell death morphology during and after a 7-day course of CORT injection. A total number of 200 one-day-old commercial Cobb broiler chicks were used in this study.

Expression of Inflammatory and Cell Death Program Genes and Comet DNA Damage Assay Induced by Escherichia coli in Layer Hens.

Modern methods of industrial poultry and egg production systems involve stressful practices that stimulate Escherichia coli (E. coli) activity causing endotoxic shock. This investigation was conducted to evaluate the expression of pro-inflammatory cytokines and cell death program genes and DNA damage induced by E.

Genetic structure of Mugil cephalus L. populations from the northern coast of Egypt.

Aim: The gray mullet, Mugil cephalus, has been farmed in semi-intensive ponds with tilapia and carps in Egypt for years. The current study used the fluorescent amplified fragment length polymorphism (F-AFLP) technique to search for genetic differences between the populations of M. cephalus in the northern region of Egypt and to detect the gene flow between sampled locations and the homogeneity within M.

Genotoxicity studies on the removal of a direct textile dye by a fungal strain, in vivo, using micronucleus and RAPD-PCR techniques on male rats.

The genotoxicity of the azo dye 'Direct Violet' and the removal of this dye by Aspergillus niger strain at different conditions have been investigated in male rats. Two genotoxicity techniques, namely bone marrow micronucleus assay and RAPD fingerprinting pattern, were used in this study for the direct dye and its removal by the fungal strain. Sixty male rats were divided into six treatment groups including a control group and other groups which were exposed for 2 or 8 weeks to Direct Violet dye, Direct Violet dye treated with A.
