Abstract

Gazella dama mhorr is an endangered species with an extant population of about 190 animals distributed between several zoos. Semen was collected by electro-ejaculation from 12 adult males, and cryopreserved in TEST-yolk diluent containing 6% glycerol. The effects of the concentration of egg yolk (5%, 10% and 20%) and the presence or absence of sodium triethanolamine lauryl sulfate (equex) on sperm motion and acrosomal integrity after thawing were examined. Increasing concentrations of egg yolk resulted in more acrosomal damage and poorer motility after thawing. The presence or absence of equex had no effect on either parameter. The frozen spermatozoa were used in an insemination trial, in which 13 females were treated with intravaginal progesterone-releasing devices to synchronize oestrus. Seven females were inseminated with frozen-thawed semen 48 h after removal of the devices, and six were inseminated after 60 h. Three females in the first group and one in the second group became pregnant. However, only one pregnancy (from the 48-h group) was carried to term. The study demonstrated the feasibility of applying artificial insemination in this species, but revealed that a number of outstanding technical problems remain to be sol...Continue Reading

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
