Fourteen new species of demosponges (Porifera) from three coastal fjords in southern British Columbia, Canada.

Collections of encrusting sponges from the shallow subtidal zone of three southern fjords in British Columbia, Canada, and adjacent waters provided the material for the description of 14 new species. Species represent 5 orders, 8 families and 11 genera providing a cross section of British Columbia shallow water fjord Demospongiae. New species include Eurypon reiswigi n.

Assessing the Association Between Animal Color and Behavior: A Meta-Analysis of Experimental Studies.

Color varies in pattern and degree across the tree of life. In animals, genetic variation in color is hypothesized to have pleiotropic effects on a variety of behaviors due to shared dependence on underlying biochemical pathways. Such pleiotropy can constrain the independent evolution of color and behavior.

Clinicians' and Patients' Experiences and Perceptions on the Prevention and Management of Surgical Site Infections: A Mixed-Methods Systematic Review.

Aim: To explore clinicians' and patients' perceptions of implementing evidence-based practice to improve clinical practice for preventing and managing surgical site infections within hospital acute care settings.

Design: A convergent integrated mixed-methods systematic review using the Joanna Briggs Institute approach.

Methods: Included studies reported (i) acute care hospital clinicians' and patients' experiences and preferences for preventing and managing surgical site infections and (ii) barriers and facilitators to implementing surgical site infection prevention and management guidelines.

Stem cell activity-coupled suppression of endogenous retrovirus governs adult tissue regeneration.

Mammalian retrotransposons constitute 40% of the genome. During tissue regeneration, adult stem cells coordinately repress retrotransposons and activate lineage genes, but how this coordination is controlled is poorly understood. Here, we observed that dynamic expression of histone methyltransferase SETDB1 (a retrotransposon repressor) closely mirrors stem cell activities in murine skin.

The Effect of Seminal Plasma on the Equine Endometrial Transcriptome.

The establishment of pregnancy involves a fine-tuned balance between protection and tolerance within the maternal immune system, as the female needs to accept a foreign antigen (the semi-allogenic fetus) while still being able to combat pathogens from the uterus. In the horse, the first uterine exposure to paternal antigens is during mating when sperm is introduced to the tissue and draining lymphatics of the uterus. Additionally, it has been suggested that seminal plasma and its proteins within it play an essential role in preparing the female tract for a suitable immunologic environment but this has not been confirmed in the horse.
