Expression And Tissue Distribution Of Extracellular Calcium-Sensing Receptor (Casr) Mrna In Chickens, Guangcun Deng, Jianmin Bi, Jian Qiao, Guiei He, Boning Wu, Miaojie Zhang, Nana Lv

Turkish Journal of Veterinary & Animal Sciences

Extracellular calcium-sensing receptor (CaSR) is a recently discovered G-protein-coupled receptor that may play a key role in regulating parathyroid hormone secretion and calcium homeostasis. In the present study, based on the reported sequence of the chicken CaSR gene (GenBank accession: XM_416491), specific primers were designed and synthesized, and CaSR gene mRNA expression and tissue distribution in chickens were analyzed using semiquantitative reverse transcriptase polymerase chain reaction (RT-PCR) analysis. It was observed that CaSR mRNA was expressed in the kidney and parathyroid to a greater degree than in the small intestine, oviduct, and brain (P < 0.01). Sequence analysis of the PCR products obtained from the 5 tissues showed that these cDNAs shared 100% homology with each other and the corresponding region of the reported CaSR cDNA. The results may provide a basis and additional insight for understanding the physiological function of CaSR in chickens.

Comparative Studies On The Sensitivity Of Polymerase Chain Reaction (Pcr) And Microscopic Examination For The Detection Of Trypanosoma Evansi In Horses, M.A. Muieed, Zafar Iqbal Chaudhry, A. R. Shakoori

Turkish Journal of Veterinary & Animal Sciences

The lack of reliable diagnostic methods is a setback in the effective control of diseases. Diagnosis of Trypanosoma evansi infection (surra) in livestock is of considerable economic importance. Detection of trypanosomes in blood has been the "gold standard"; however, finding the organisms or establishing patency of parasitaemia has not always been possible even in symptomatic infections. As a consequence of low dose infection, the pre-patent period in Trypanosoma evansi may be longer and, even when symptoms have developed, trypanosomes may still not be demonstrable in blood, thus delaying treatment and thereby increasing morbidity and mortality. Trypanosoma evansi, a protozoan parasite …

Also, plasma samples were obtained from the subjects. Results: In the erythrocyte hemolysate, MDA (malondialdehydes) levels and SOD (superoxide dismutase) activities were found to be lower (P < 0.01) in the second samples compared to the first ones. Conclusion: We think that because free radical production was decreased SOD activities were not increased. Our results show that reduced peroxidation processes caused by Maraş grape consumption suggest that grape consumption has beneficial effects in elderly subjects.

Dendritic cells (DCs) are potent antigen-presenting cells crucial for initiation of cell-mediated immune responses to foreign antigens. They also contribute to the innate resistance against microbial pathogens. The present study examined the effect of microorganisms such as Escherichia coli (E. coli), Serratia marcescens (S. marcescens), Methicillin-resistant Staphylococcus aureus (MRSA), coagulase negative staphylococci (CoNS), and Candida albicans (C. albicans) on cytokine secretion in bone marrow-dendritic cells (BM-DCs). Materials and methods: The levels of cytokines in culture supernatants of the BM-DC were determined by enzyme-linked immunosorbent assay. Results: DCs stimulated by microorganisms produced large amounts of TNF-\alpha, IL-1\beta, IL-6, and IL-10. The …

Fluoride intake in high doses has toxic effects on various organs. Chronic fluorosis results in tubular degenerations, inflammation, fibrosis, parenchymatous nephritis, cloudy swellings, and dilations of convoluted tubules. In addition to these effects, fluoride causes deteriorative effects on the skeleton, teeth, and soft tissues. The goal of this study was to examine the impacts of chronic fluorosis on the liver tissues of mice. Materials and methods: One control group and 3 experimental groups, each group consisting of 4 male and 4 female mice, were formed to conduct the experiment.
