Impact of redox status of donor cows before superovulation treatment on in vivo embryo production.

This study investigated the relationship between oxidation and antioxidation parameters before superovulation (SOV) treatment and embryo recovery in donor cows. The relative redox status of the 61 donor cows was evaluated based on the median values of diacron-reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) measurements (d-ROMs of 100 U.CARR; BAP of 2413  mol L ) before SOV treatment.

Novel Approach for Evaluating Pregnancy-Associated Glycoprotein and Inflammation Markers during the Postpartum Period in Holstein Friesian Cows.

We evaluated the relationship between decreased pregnancy-associated glycoprotein (PAG) levels, inflammatory parameters (serum amyloid A [SAA] and milk amyloid A [MAA]), postpartum inflammatory conditions (mastitis, ketosis, and follicular cysts), and the gene. Nineteen Holstein-Friesian cows were included in this study. Up to approximately eight weeks after delivery, weekly health examinations were performed for mastitis and ketosis, and reproductive organ ultrasonography was performed.

Increase in Streptococcal Necrotizing Fasciitis During and After the Coronavirus Disease 2019 Pandemic.

Necrotizing fasciitis (NF) is a life-threatening and rare condition. However, we report and analyze a remarkably high number of NF cases during the coronavirus disease 2019 (COVID-19) pandemic and especially in the first months after the COVID-19 pandemic. We conducted a retrospective analysis of 17 cases of NF treated in our clinic between January and May 2023.

Selection of spermatozoa with high motility and quality from bovine frozen-thawed semen using the centrifuge-free device.

This study aimed to assess the potential of the centrifuge-free commercial device (MIGLIS®) in selecting functional frozen-thawed bovine sperm by migration-sedimentation, its effect on embryo development, and compare the potential with that of centrifugation-based techniques, including washing and Percoll density gradient centrifugation (DGC). In experiment 1, different dilutions (1.5×, 2×, and 3×) of frozen-thawed spermatozoa were assessed to identify the adequate one for the MIGLIS method.
