BACKGROUND AND OBJECTIVE Renal denervation has recently become of great interest as a potential treatment for resistant hypertension. Denervation techniques using radio frequency (RF) or ultrasound energy sources have already been explored in literature. In this study, we investigate the use of lasers as a potential energy source for renal denervation. In vitro studies are performed in porcine/...
Prion diseases are characterized by a conformational change in the normal host protein PrPC. While the majority of mature PrPC is tethered to the plasma membrane by a glycosylphosphatidylinositol anchor, topological variants of this protein can arise during its biosynthesis. Here we have generated Drosophila transgenic for cytosolic ovine PrP in order to investigate its toxic potential in flies...
Eight chlamydial isolates of ovine origin were tested in a plaque reduction system using homologous and heterologous rooster antisera. The eight isolates could be separated into two separate immunotypes. Type 1 included isolates associated with ovine abortion and one agent recovered from the feces of an apparently normal sheep. Type 2 isolates were associated with polyarthritis and conjunctivit...
N. caninum could cause abortion in small ruminants. The aim of the study was to detect N. caninum infection in ovine aborted foetuses in the Mashhad area by PCR examination. During the period 2009 to 2013, 71 ovine aborted foetuses were collected and their brain samples examined by PCR. Of the 71 brains of the aborted foetuses, N. caninum DNA was detected in seven (9.8%) samples. In conclusion,...
This report describes a DNA variant in the ovine cystic fibrosis transmembrane conductance regulator (CFTR) gene that has been previously reported as a putative cystic fibrosis causing mutation in humans. The variant is a guanine to adenine base change at position 1019 of the ovine CFTR cDNA, corresponding to an arginine (R) to glutamine (Q) amino acid substitution at position 297 in the predic...
Ovine chorionic somatomammotropin (oCS) enhances the weight and bone growth of hypophysectomized rats. It acts as a bifunctional hormone, since it binds both to lactogenic and somatotropic receptors. Ovine foetus weight gain is closely related to oCS and oGH serum levels. oCS is able to stimulate somatomedins by foetal liver. Moreover, oCS specific receptors are present in some foetal tissues. ...
A search for specific placental lactogen binding was undertaken in tissues obtained from late pregnant rabbits using the placental lactogens from sheep, cows, and human beings. 125I-labeled ovine lactogen exhibited highest specific binding to the adrenal gland (57.8%), followed by liver (21.5%), ovary (19.9%), mammary gland (15.9%), uterus (12.2%), kidney (8.8%), brain (8.5%), and adipose tissu...
Background: The developmental competence of oocytes matured in vitro (IVM) is yet far below than in vivo counterparts. Recent studies suggest that the asynchrony between nuclear/cytoplasmic maturation and the initial low/heterogeneous quality of oocytes are the most important factors affecting IVM success. We investigated whether selection of growing oocytes (based on their glucose 6- phosphate...
background: recognition of helminth-derived pathogen associated molecular patterns (pamps) by pattern recognition receptors (prrs), including toll like receptors (tlrs) is the first step towards initiating anti–helminth immune responses. methods : using somatic antigens of ostertagia occidentalis, an important abomasal parasite of ruminants, the expression of ovine tlr2 and tlr4 in peripheral...
