Post-warming quality of goat oocytes under heat shock stress: A study of the maturation rate, heat shock protein-70, adenosine triphosphate, and glutathione levels [PDF]

Veterinary World
Background and Aim: Indonesia’s indigenous Kacang goat population is in decline, posing a threat to food security and genetic diversity. In vitro maturation and cryopreservation techniques are key strategies for genetic conservation.

Use of retinoids during oocyte maturation diminishes apoptosis in caprine embryos [PDF]

, 2015
Exposure of caprine oocytes and embryos to retinoids enhances embryonic development, but the mechanisms governing this phenomenon have not been characterised.

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...

Effect of blood plasma collected after adrenocorticotropic hormone administration during the preovulatory period in the sow on oocyte in vitro maturation [PDF]

, 2013
Reproduction may be affected by stressful events changing the female endocrine or metabolic profile. An altered environment during oocyte development could influence the delicate process of oocyte maturation. Here, the effect of simulated stress by media

Growth Differentiation Factor 9 Supplementation Restores the Lipopolysaccharide-Induced Negative Effects on Bovine Oocyte Developmental Competence. [PDF]

Mol Reprod Dev
ABSTRACT Growth differentiation factor 9 (GDF9) plays a key role in enhancing developmental competence and blastocyst yield during in vitro maturation (IVM). This study investigated whether GDF9 could counteract the harmful effects of lipopolysaccharide (LPS), a gram‐negative bacterial component, on bovine in vitro embryo production, while also ...

Bovine Follicular Dynamics, Oocyte Recovery,and Development of Oocytes Microinjected with a Green Fluorescent Protein Construct [PDF]

, 1999
The present study was carried out to 1) evaluate the viability of in vitro fertilized zygotes after microinjection of DNA, 2) assess the influence of oocyte quality upon the development rate of embryos when injected with DNA, and 3) determine the ...

Goat incubator: Can bovine oocytes be matured in the uterine horn of a goat?

Semina: Ciências Agrárias, 2019
We used a goat as a live incubator, along with associated nonsurgical embryo transfer techniques, to perform ex situ (in vivo) maturation of bovine oocytes.
