Sheep Corneal Endothelium Morphology - Evaluation with Trypan Blue and Alizarin Red

open access: yesActa Scientiae Veterinariae, 2022
Background: The endothelium is a layer fundamental to maintaining corneal transparency. In ophthalmology, sheep eyes have been used as a model in research related to corneal transplantation. Different techniques have been used to evaluate the corneal endothelium.

Climate Change and Human Pressure: Assessing the Vulnerability of Snow Leopard (Panthera uncia) Habitat Integrated With Prey Distribution on the Qinghai‐Tibet Plateau [PDF]

open access: yesEcology and Evolution
Climate change is significantly altering the distribution of large carnivores and their primary prey species, with particular emphasis on the changing prey distribution in high‐altitude regions. The Qinghai‐Tibet Plateau, known for its rich biodiversity,

Estimation of blood (plasma) volume in sheep with Evans blue and bromsulphalein.

open access: bronzeNetherlands Journal of Agricultural Science, 1985
Tests in a wether fitted with a jugular catheter showed that, after application of correction factors calculated by multiple regression analysis, blood volume could be measured with Evans Blue and blood plasma volume with bromsulphalein. Mean haematocrit value corresponded to 28% of the blood volume and 22.8% of the blood plasma volume.

Cardiopulmonary Hemodynamics of Blue-Sheep, Pseudois nayaur, as High-Altitude Adapted Mammals

open access: bronzeThe Japanese Journal of Physiology, 2003
The blue-sheep, pika, and yak live in the Tibetan highlands at an altitude of 6,100 m and are typical mammals adapted to high-altitudes. These animals have a long history of habitation at high-altitudes and are considered to be "animals completely adapted to high-altitudes" because of their physiological and morphological traits that are well adapted ...

Sex identification based on AMEL gene PCR amplification from blue sheep (Pseudois nayaur) fecal DNA samples

open access: bronzeGenetics and Molecular Research, 2015
The use of noninvasive genetic sampling to identify the sex of wild animals is an extremely valuable and important tool in molecular ecology and wildlife conservation. Sex determination using the amelogenin gene has been conducted in many species because

Behavioral responses of blue sheep (Pseudois nayaur) to nonlethal human recreational disturbance [PDF]

open access: yesChinese Science Bulletin, 2013
Nonlethal human recreational activities have been confirmed to have negative effect on wild animals in a number of ways, including changes in behaviors, avoidance of suitable habitats and declines in breeding success. Studies on the anti-disturbance mechanism of wild animals to human disturbance can provide valuable knowledge to the management of wild ...

Effect of methylene blue on the vasodilator action of inhaled nitric oxide in hypoxic sheep

open access: bronzeBritish Journal of Anaesthesia, 1994
We have examined the effect of methylene blue 4mg kg-1 on the pulmonary vasodilator action of inhaled nitric oxide (8, 32, 128 and 512 volumes per million) in nine sheep with pulmonary hypertension induced by hypoxia (FlO2 = 0.12). The dose-response to nitric oxide was unchanged by methylene blue, but increased cardiac output was noted (P < 0.01 ...
