Effects of 5G radiofrequency electromagnetic radiation on indicators of vitality and DNA integrity of in vitro exposed boar semen.

The effects of radiofrequency electromagnetic radiation (RF-EMR) on semen quality have been in the spotlight in recent years, though research results to date have been contradictory. The effects of RF-EMR amongst others depend upon frequency, and there is currently no literature concerning the influence of 5G frequencies on both DNA integrity and spermatozoa vitality in males. The aim of this study was to investigate the effect of 5G RF-EMR on sperm membrane integrity, mitochondrial potential, and DNA integrity of in vitro exposed semen of breeding boars.

The Distribution of Boars Spermatozoa in Morphometrically Distinct Subpopulations after In Vitro Exposure to Radiofrequency Electromagnetic Radiation at 2500 MHz and Their Motility.

Anthropogenic radiofrequency electromagnetic radiation (RF-EMR) from wireless technologies has increased dramatically. The boar semen used for artificial insemination is essential in sustaining the pig industry, and additionally it is also exposed to the effects of the RF-EMR of wireless technologies. Furthermore, there are no data on the effects of RF-EMR on semen quality, and this is the first analysis of sperm's morphometric parameters for assessing the effect of RF-EMR on the spermatozoa subpopulations of boars.

Effects of in-feed clinoptilolite treatment on serum metabolic and antioxidative biomarkers and acute phase response in dairy cows during pregnancy and early lactation.

The objective of this study was to evaluate the effects of in-feed clinoptilolite (CPL) on serum metabolic and antioxidative biomarkers, acute phase proteins and reproductive performance in cows during pregnancy and lactation. A total of 78 Holstein-Friesian cows were randomly assigned into two groups: the treatment group, cows fed CPL (n = 38) which received 50 g of powdered CPL twice a day from day 180 before parturition to day 60 postpartum; and the control group (n = 40). Blood samples were taken on days 180, 90, 60, 30 and 10 before parturition, on day of calving and on days 5, 12, 19, 26, 33, 40 and 60 postpartum, and were analysed for metabolic biomarkers: glucose, triglycerides, total cholesterol, high density lipoprotein cholesterol, non-esterified fatty acids, beta-hydroxybutyrate (BHB), antioxidative biomarkers and acute phase proteins: paraoxonase-1 (PON1), apolipoprotein A-I, haptoglobin (Hp) and serum amyloid A (SAA).

Endometrial Mucinous Adenocarcinoma in a Bitch With Pyometra-A Case Report.

Endometrial adenocarcinomas present rare neoplasia of bitches. This case report describes mucinous endometrial adenocarcinoma in a bitch with concurrent pyometra for the first time. A mass on the uterine stump was removed during surgery of a 13-year-old bitch with clinically suspected pyometra.
