To evaluate effects of different concentrations of nanosilver colloid on the cell culture of Sertoli cells, the proportion of lipid peroxidation, antioxidant capacity, nitric oxide (NO) production and genes expression of superoxide dismutases (SOD1 and SOD2) and nitric oxide synthases (eNOS and iNOS) were measured. Sertoli cells were incubated at(More)
To investigate the effect of T(3)-induced pulmonary hypertension on endothelin (ET) production and genes expression of ET-1, ET(A) and ET(B) receptors (ET(A)R and ET(B)R) during rearing, semiquantitative RT-PCR and enzyme immunometric assay were performed in the heart ventricles and serum, respectively. The ET-1 and its receptor genes were expressed in the(More)
ETHNOPHARMACOLOGICAL RELEVANCE Kelussia odoratissima Mozzaf, formerly Apium odoratissima, is a plant locally called "Karafs", found in central Zagros region of Iran. Leaves and stems of the plant are traditionally used in the treatment of hypertension and inflammation. Lowering blood pressure effects of Kelussia odoratissima Mozzaf (wild celery) was(More)
1. There are few studies on the effect of dietary protein content on pulmonary hypertension syndrome (PHS) in broiler chickens. Conflicting results from these studies prevent a clear conclusion on the effects of reduced-protein diets on development of the syndrome. 2. To obtain an understanding of the mechanisms involved, the current study, conducted at a(More)
BACKGROUND BACKGROUND Despite major progress in our general knowledge related to the application of adult stem cells, finding alternative sources for bone marrow Mesenchymal Stem Cells (MSCs) has remained to be challenged. In this study successful isolation, multilineage differentiation, and proliferation potentials of sheep MSCs derived from bone(More)
To clarify the effect of cold-induced pulmonary hypertension on endothelial and inducible nitric oxide synthase (eNOS and iNOS) mRNA expression in the lung of broiler chickens, semi quantitative reverse transcription-PCR was performed on total RNAs isolated from lungs of the broiler chickens exposed to 5 weeks of cold stress. The eNOS gene was expressed(More)
A total of 300 male broilers (Ross 308) were exposed to cool conditions at high altitudes to study the effects of dietary Arg supplementation on performance and physiological and zootechnical variables. A corn-soybean meal (SBM) and a corn-canola meal (CM) diet were formulated for the starting (1 to 3 wk of age) and growing (3 to 6 wk of age) stages(More)
1. To clarify the effect of T(3)-induced pulmonary hypertension on endothelial and inducible nitric oxide synthase (eNOS and iNOS) mRNA expression in the ventricles of the heart, semi quantitative reverse transcription-PCR was performed on total RNAs isolated from broiler chicken hearts after feeding supplementary T(3) (15 mg T3/kg) for 6 weeks. NO(More)
The aim of present study was to characterize nitric oxide production via nitrite measurement as its stable metabolite in the different species of spermatozoa (human, bull and ram). Sperm samples were fractionated on the basis of density with the use of a three-layer Percoll gradient. Spermatozoa collected from the various percoll gradient interfaces (50/70(More)
PURPOSE To report a case of idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) syndrome associated with positive perinuclear antineutrophil cytoplasmic antibody (P-ANCA). CASE REPORT A 51-year-old man presented with loss of vision in his right eye since many years ago and blurred vision in his left eye over the past year. Ophthalmologic(More)
