Embryotoxicity Evaluation of Novel Synthetic Cannabinoid 4F-MDMB-BUTICA Using Zebrafish Embryos.

Detailed studies on the embryotoxic and teratogenic effects of synthetic cannabinoids known to be abused are very limited. The present study aimed to evalutate the possible embryotoxic, teratogenic, behavioral, and molecular effects of 4F-MDMB-BUTICA, a new generation synthetic cannabinoid, using zebrafish embryos. The zebrafish embryos were exposed to the cannabinoid at 0.

Effects of Intrauterine Isoproterenol Administration on Ovarian Follicular Development in Cows.

Background: Isoproterenol (ISO) is a nonselective beta-adrenergic receptor agonist known for its vasodilatory effects. This experiment aims to investigate whether intrauterine ISO administration could alter vascular indices and follicular development in postpartum Holstein cows.

Objectives: The objectives are to evaluate the effects of intrauterine ISO administration on vascular changes and its impact on follicular development compared to placebo groups.
