Despite the widespread nature of its approach in health education, its application in basic veterinary subjects remains poorly described. This study explores the implementation of the FC approach in veterinary physiology, biochemistry, anatomy, and embryology. Pre-class material was mainly provided in video format, and class sessions facilitated quizzes and interactive activities aimed to reinforce understanding. The findings indicate a high level of student involvement and effective class preparation, as evidenced by over 84% of students participating in FC in-class sessions and generally achieving satisfactory scores on quizzes. A survey conducted at the end of the first semester shows that a high proportion of students positively valued pre-class material (>90%), quizzes (82%), and the FC approach (66%). However, by the end of the second semester, traditional lectures were preferred by more students than FC (45% and 25%, respectively), while 30% of the students mentioned having no preference between the two methods. Analysis of open-ended responses underscored positive facets of the FC approach, including self-organization, enhanced understanding, and availability of pre-class material. However, it also emphasized challenges associated with FC, such as the significant time and effort required.

ART procedures like rederivation of embryos by vitrification differ from natural conditions, causing significant disparities between in vitro and in vivo embryos, affecting foetal physiology and postnatal life. This study aims to investigate whether hepatic transcriptome and metabolome changes observed postnatally are already present in foetal livers at the end of gestation. This study compared fresh and vitrified rabbit embryos, finding differences between foetuses obtained by the transfer of fresh and vitrified embryos at 24 days of gestation. Rederived embryos had reduced foetal and liver weights and crown-rump length. However, the offspring of vitrified embryos tended to be born with higher weight, showing compensatory growth in the final week of gestation (59.2 vs. 49.8 g). RNA-Seq analysis revealed 43 differentially expressed genes (DEGs) in the foetal liver of vitrified embryos compared to the fresh group. Notably, downregulated genes included BRAT1, CYP4A7, CYP2B4, RPL23, RPL22L1, PPILAL1, A1BG, IFGGC1, LRRC57, DIPP2, UGT2B14, IRGM1, NUTF2, MPST, and PPP1R1B, while upregulated genes included ACOT8, ERICH3, UBXN2A, METTL9, ALDH3A2, DERPC-like, NR5A2-like, AP-1, COG8, INHBE, and PLA2G4C.
