Temperature-dependent inhibition of motility in spermatozoa from different avian species

Animal Reproduction Science
G J Wishart, Y I Wilson

Abstract

This study demonstrates that the pattern of temperature-dependent inhibition of chicken sperm motility at 40 degrees C in vitro, and its release by calcium, is also found in drake spermatozoa and, partially, in turkey spermatozoa. However, no such temperature-dependent inhibition was found in spermatozoa from Japanese quail and Houbara bustard, for which physiological levels of calcium at 40 degrees C had an inhibitory and no effect on sperm motility, respectively. Thus, on the basis of this evidence on the regulation of avian sperm motility in vitro, the hypothesis that oviducal sperm storage tubules might immobilise spermatozoa by providing a calcium-free environment in vivo does not appear to be universally applicable to all species of birds.

COVID-19

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.
