Ovine placenta at high altitudes: Comparison of animals with different times of adaptation to hypoxic environment
(ELSEVIER, 2006-09)
Fetal growth and newborn weight from ovine gestations at high altitudes (HA) are greater in ewes that live at HA for several generations than in those native to low altitudes (LA) exposed to HA only during pregnancy. Because ...
Comparative ex vivo infection with Trypanosoma cruzi and Toxoplasma gondii of human, canine and ovine placenta: Analysis of tissue damage and infection efficiency
(Elsevier, 2020)
Trypanosoma cruzi, the causative agent of Chagas disease, and Toxoplasma gondii, which is responsible for Toxoplasmosis, are two parasites that cause significant protozoan zoonoses and consequently important economic losses ...
Effects of catecholamines on secretion of interferon tau and expression of genes for synthesis of polyamines and apoptosis by ovine trophectoderm
(2018)
Ovine trophectoderm (oTr1) cells were used to investigate effects of epinephrine (EP), norepinephrine (NE), and dopamine (DA) on their proliferation, migration and adhesion, secretion of interferon tau (IFNT), and expression ...
Effects of Bisphenol-A on proliferation and expression of genes related to synthesis of polyamines, interferon tau and insulin-like growth factor 2 by ovine trophectoderm cells
(2018)
This study evaluated the effects of bisphenol A (BPA) on proliferation of ovine trophectoderm (oTr1) cells, as well as expression of genes for transport of arginine and synthesis of polyamines. BPA reduced proliferation ...
Effects of BPA on expression of apoptotic genes and migration of ovine trophectoderm (oTr1) cells during the peri-implantation period of pregnancy
(2019)
Bisphenol A (BPA) is an endocrine-disrupting chemical used in the manufacture of many products used daily. In the present study, the effects of BPA (1 × 10 −4 to 1 × 10 -9 M) on migration and on the expression of some ...
A model of pediatric end-stage lung failure in small lambs <20 kg
(Lippincott Williams & Wilkins, 2020)
One in five children with end-stage lung failure (ESLF) die while awaiting lung transplant. No suitable animal model of ESLF exists for the development of artificial lung devices for bridging to transplant. Small lambs ...
Nuclear chromatin decondensation of spermatozoa in vitro: a method for evaluating the fertilizing ability of ovine semen
(1985)
Spermatozoa obtained from testes, epididimydes and complete ejaculates of healthy rams during the breeding and non‐breeding seasons were induced to show nuclear chromatin decondensation by controlled exposure to dithiotreitol ...

Supplementation of underfed twin-bearing ewes with herbal vitamins C and E: Impacts on birth weight, postnatal growth, and pre-weaning survival of the lambs
(MDPI, 2020)
Simple Summary In twin-bearing ewes, undernourishment during pregnancy lowers the birth weight and increases morbidity and mortality of lambs. One of the causes is oxidative stress, which can be prevented by supplementing ...
Melatonin long-lasting beneficial effects on pulmonary vascular reactivity and redox balance in chronic hypoxic ovine neonates
(Wiley, 2020)
Pulmonary arterial hypertension of the neonate (PAHN) is a pathophysiological condition
characterized by maladaptive pulmonary vascular remodeling and abnormal
contractile reactivity. This is a multifactorial syndrome ...
