Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Synergistic RU486 and olaparib therapy enhances apoptosis in endometriosis by simultaneously targeting hormonal signalling and DNA repair

British Journal of Pharmacology, EarlyView.
Background and Purpose Endometriosis is a chronic, hormone‐dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is effective for pain relief, its impact on lesion regression is limited, possibly due to apoptosis resistance and ...

Cannabidiol and cannabigerol ameliorate steatotic liver disease via phosphocreatine buffering and lysosomal restoration

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) and cannabigerol (CBG) alleviate hepatic steatosis in obese mice by shifting energy buffering towards phosphocreatine and enhancing lysosomal lipid degradation and trafficking. These effects are associated with increased creatine kinase activity and lysobisphosphatidic acid (LBPA) levels, highlighting a previously unrecognised ...

Inositol and Berberine Synergistically Reprogram Endocrine and Ovarian Metabolism in Polycystic Ovary Syndrome

Cell Proliferation, EarlyView.
In a DHEA+HFD‐induced mouse model, Ins/BBR alleviated mitochondrial defects and broadly reprogrammed metabolic landscape in granulosa cells, in specific, restoring nucleotide pools and amino acid turnover, and preventing abnormal long‐chain fatty acid accumulation.

Estrous cycle manipulation in cats

Clinical Theriogenology
For decades, interest in reproductive physiology of the domestic cat has largely been driven by its importance as a model for wild felids and human biomedical research. As such, several assisted reproductive technologies have been established in cats.

Cortisol and heart rate response of mares during the in‐hand breeding procedure with and without restraint

Equine Veterinary Journal, EarlyView.
Abstract Background In‐hand breeding involving restraint methods is likely the most common practice in the horse breeding industry worldwide. However, welfare issues that arise from such management have not been investigated in detail. Objectives (1) To investigate whether the mares show increased stress responses during in‐hand breeding using (a) a ...
