Purpose: To demonstrate the efficacy of DIVENCE, a vaccine against BVDV types 1 and 2 (BVDV-1 and BVDV-2) transplacental infection, following a booster regimen in heifers.

Materials And Methods: Calves of two-to-three months of age were given two intramuscular doses three weeks apart and a booster vaccine six months later. Efficacy was evaluated by means of a challenge with virulent BVDV-1 or BVDV-2 administered via the intranasal route at 85 days of gestation.

A new multivalent vaccine (DIVENCE), containing live gE/tk double-gene-deleted BoHV-1, live-attenuated BRSV, inactivated PI3, and BVDV-1, and BVDV-2 recombinant proteins, has been designed to protect cattle against the main viral pathogens associated with bovine respiratory disease (BRD). The aim of this study was to demonstrate the efficacy of DIVENCE against BRD in field conditions. A total of 360 animals from three different farms were included in this study.

Article Synopsis
  • Telomeres are protective caps on chromosomes, and their length is related to aging and diseases, prompting a study on telomere length in over 462,000 UK Biobank participants.
  • Researchers created a new metric for measuring telomere length that improved understanding of its genetic control and identified 64 genetic variants and 30 genes linked to telomere length.
  • Notably, many of these genes are involved in clonal hematopoiesis, which is linked to certain cancers, indicating a complex relationship between rare genetic variants and telomere length.

The etiology of prostate cancer, the second most common cancer in men globally, has a strong heritable component. While rare coding germline variants in several genes have been identified as risk factors from candidate gene and linkage studies, the exome-wide spectrum of causal rare variants remains to be fully explored. To more comprehensively address their contribution, we analysed data from 37,184 prostate cancer cases and 331,329 male controls from five cohorts with germline exome/genome sequencing and one cohort with imputed array data from a population enriched in low-frequency deleterious variants.
