Article Synopsis
- - This study examined ways to improve assisted reproductive techniques for conserving wild cats, using domestic cats as a reference.
- - Researchers tested three types of in vitro culture media to see how they influenced the formation of blastocysts, finding similar success rates of over 16%.
- - The study shows promise for these reproductive methods but suggests more research is needed to assess embryonic quality and enhance protocols for conserving wild felids.
The present study aimed to evaluate whether primed anoestrus mares are suitable recipients for embryos produced by intracytoplasmic sperm injection (ICSI). Anoestrus was confirmed in four mares and daily doses of oestradiol benzoate (6 mg in total) over 5 days were administered; after 3 days of rest, oral altrenogest was administered at 0.088 mg/kg and embryos (1 to 5 embryos per mare; 15 in total) were transferred 3.
View Article and Find Full Text PDFOvum Pick Up (OPU) is a minimally invasive technique widely used in cattle and mares for oocyte retrieval, involving ultrasound-guided puncture of ovarian follicles. It has been demonstrated that this technique is safe for its repeated use in the same female without affecting her reproductive health, allowing for the retrieval of oocytes in individuals regardless of their reproductive status. The oocytes obtained through OPU can subsequently be used for in vitro embryo production (IVP) using assisted reproductive techniques (ARTs) or be cryopreserved in biobanks for their future use.

- The study investigates the effects of a 4-week β-alanine supplementation on neuromuscular fatigue and sports performance in individuals performing High-Intensity Functional Training (HIFT).
- A randomized controlled trial with 27 participants compared β-alanine (experimental group) to a sucrose powder placebo (control group) over four weeks, focusing on fatigue and performance metrics.
- Results showed that β-alanine supplementation significantly improved vertical jump and jumping power but did not affect overall fatigue or exercise intensity.
The number of two-toed sloths () has significantly decreased in the last years. Deepening the knowledge of this tropical mammal's reproductive physiology is essential to improve captive breeding within conservation programs for this species. However, several aspects of its reproductive biology remain unexplored and have not been described sufficiently.
