Hair follicle stem cells (HFSCs) possess fascinating self-renewal capacity and multipotency, which play important roles in mammalian hair growth and skin wound repair. Although HFSCs from other mammalian species have been obtained, the characteristics of ovine HFSCs, as well as the methods to isolate them have not been well addressed. Here, we report an efficient strategy to obtain multipotent ...

The preimplantation ovine conceptus transiently secretes several proteins, including a type I interferon (IFN-tau), that are likely involved in establishment of pregnancy. A method has been developed to identify proteins produced simultaneously with IFN-tau. An antiserum against total ovine conceptus secretory proteins, from which IFN-tau and proteins common to maternal uterine tract secretions...

A series of experiments were conducted to determine whether and under what conditions central prolactin (PRL) administration would stimulate the onset of maternal behavior in female rats and to identify possible neural sites of PRL action. In each experiment ovariectomized, nulliparous rats whose endogenous PRL levels were suppressed with bromocriptine were tested for maternal behavior toward f...

OBJECTIVE To determine: 1) placental eNOS mRNA concentration across gestation in normal ovine pregnancy and in an ovine model of intrauterine growth restriction (IUGR), and 2) placental eNOS protein concentration in early ovine pregnancy. STUDY DESIGN A total of 24 sheep were studied with 12 ewes placed in hyperthermic (HT) conditions to induce IUGR and 12 were kept in control conditions. HT ...

Ornithine transcarbamoylase from ovine liver has been purified to homogeneity. Like all anabolic OTCs, the ovine enzyme is a trimer, constituted by identical subunits of 34 kDa. Sequence analysis of the 54 N-terminal residues of ovine OTC shows a high degree of homology with the human enzyme. The optimum pH and the Michaelis constants for the catalytic reaction were determined. The ovine enzyme...

Ticks and tick-borne diseases, including theileriosis, constitute a major constraint to livestock production. Two species, known as Theileria lestoquardi and Theileria ovis, are suspected to contribute to ovine theileriosis in Iran. However, the epidemiological aspects of ovine theileriosis are poorly understood in this country. In a survey, designed to identify Theileria species in sheep, 52 (...

background and aims: the aim of this study was to determine the virulence and antibiotic resistance properties of streptococcus agalactiae (s. agalactiae) and streptococcus uberis (s. uberis) isolated from the ruminant’s sub-clinical mastitic milk in iran. materials and methods: positive samples in the cmt test were cultured and s. agalactiae and s. uberis have been identified using biochemical...

Sheep (ovine) pulmonary adenocarcinoma (SPA), also known as ovine pulmonary adneomatosis (OPA),jaagsiekte and ovine pulmonary carcinoma (OPC) is a contagious lung tumor in sheep and, more rarely, ingoats. This study was carried out in Khuzestan, in the southwest of Iran for a period of six months. A totalnumber of 3985 native breed goats were clinically inspected and postmortem examination was ...
