Comparisons among selected neonatal biomedical parameters of four species of semi-free ranging Hippotragini: Addax (Addax nasomaculatus), scimitar-horned oryx (Oryx dammah), Arabian oryx (Oryx leucoryx), and sable antelope (Hippotragus niger)

Basic biomedical data from 164 neonates of four species of the tribe Hippotragini, addax (Addax nasomaculatus), scimitar-horned oryx (Oryx dammah), Arabian oryx (Oryx leucoryx), and sable antelope (Hippotragus niger), were compared at one zoological institution over a 9-year period. Measured biomedical parameters included body weight, temperature, pulse and respiratory rates, packed cell volume (PCV), total plasma protein, glucose, IgG assessment via zinc sulfate turbidity, and white blood cell count with differential. All species were maintained in a semi-free ranging setting with the same diet, available shelter, and opportunity for social interaction. Based on clinical and field observations, all neonates used in the study were believed to be at least 24 hr old, to have bonded with the dam, and to have no obvious physical abnormalities. Median body weights were similar only in the addax and Arabian oryx with sable antelope having the largest median body weight. No significant differences in rectal temperatures or pulse rates were found among species. Median respiratory rates were similar between certain groups. Arabian oryx and scimitar-horned oryx shared the highest packed cell volumes while the sable antelope had the lowes...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
