Genetic selection for the best suited offspring drives the dairy industry to use young genitors and assisted reproductive technologies (ART) to reduce generation intervals. However, sperm samples collected from peri-pubertal bulls have lower counts and quality compared to samples from adult bulls. Moreover, our previous study identified differentially methylated regions (DMRs) in sperms from early-, peri- and post-pubertal bulls. The aim of this study was to further investigate the impacts of paternal age on early embryos. To achieve this, we evaluated the transcriptome and the epigenome of bovine blastocysts generated from spermatozoa of bulls at 10, 12, and 16 months of age and used in vitro fertilization (IVF) of oocytes recovered from the same adult cows. A total of 259 probes were differentially expressed and 6953 probes were differentially methylated in the 10- vs 16-month and the 12- vs 16-month groups. Ingenuity Pathway Analysis (IPA) of transcriptomic data demonstrated that energy-related pathways such as oxidative phosphorylation, EIF2 signaling, and mitochondrial dysfunction were affected the most by the age of the bull. Meanwhile, IPA analysis of the epigenome revealed that protein kinase A signaling, RAR activation, and other pathways were influenced by paternal age. Overall, we showed that the bull's age mainly influenced metabolism-related pathways in blastocysts, and this could therefore impact subsequent development.

Bovine viral diarrhea (BVD) is caused by the BVD virus (BVDV) and has been reported worldwide in cattle. To estimate BVDV circulation among cattle where few BVD cases were reported in southern Japan, 1910 serum samples collected from 35 cattle farms without a BVD outbreak were investigated to detect antibodies against BVDV-1 and BVDV-2 using an indicator virus with a cytopathogenic effect and the luciferase gene, respectively. Neutralizing antibodies against BVDV-1 and BVDV-2 were detected more frequently in 18 vaccinated farms than in 17 nonvaccinated farms.

Tuberculosis (TB), a human and animal disease caused by (), has the highest global mortality rate after coronavirus disease 2019 (COVID-19) and poses a major public health threat globally. Since 1890, vaccine candidates for various forms of TB have been developed for different age groups, but these vaccine candidates have not provided intended protection in adolescents and adults in clinical trials. To help prevent and control the spread of TB, the development of a safe and effective TB vaccine is imperative.

Bone sarcomas, constituting less than 1% of malignant neoplasms across all age groups, are rare tumours possibly associated with genetic susceptibility syndromes. This review aims to provide recommendations for the detection of cancer predisposition syndromes associated with bone sarcomas and managing affected patients. Recommendations were formulated by a multidisciplinary working and reviewing group from GROUPOS and SFCE oncogenetic's group, including geneticists, oncologists, and radiologists.
