Biochemical and Hematologic Reference Intervals for Anesthetized, Female, Juvenile Yorkshire Swine.

Swine are widely used in biomedical research, translational research, xenotransplantation, and agriculture. For these uses, physiologic reference intervals are extremely important for assessing the health status of the swine and diagnosing disease. However, few biochemical and hematologic reference intervals that comply with guidelines from the Clinical and Laboratory Standards Institute and the American Society for Veterinary Clinical Pathology are available for swine. These guidelines state that reference intervals should be determined by using 120 subjects or more. The aim of this study was to generate hematologic and biochemical reference intervals for female, juvenile Yorkshire swine (Sus scrofa domesticus) and to compare these values with those for humans and baboons (Papio hamadryas). Blood samples were collected from the femoral artery or vein of female, juvenile Yorkshire swine, and standard hematologic and biochemical parameters were analyzed in multiple studies. Hematologic and biochemical reference intervals were calculated for arterial blood samples from Yorkshire swine (n = 121 to 124); human and baboon reference intervals were obtained from the literature. Arterial reference intervals for Yorkshire swine differed significantly from those for humans and baboons in all commonly measured parameters except platelet count, which did not differ significantly from the human value, and glucose, which was not significantly different from the baboon value. These data provide valuable information for investigators using female, juvenile Yorkshire swine for biomedical re- search, as disease models, and in xenotransplantation studies as well as useful physiologic information for veterinarians and livestock producers. Our findings highlight the need for caution when comparing data and study outcomes between species.

Rapid Coating Process Generates Omniphobic Dentures in Minutes to Reduce C. albicans Biofouling.

Localized infections caused by biofilm formation on dentures pose a serious health risk for patients, especially the elderly, as they can lead to complications such as pneumonia. Daily enzymatic denture cleaners do not fully prevent biofilm formation on dentures. Here we developed a rapid coating process to apply a liquid repellent surface to dentures in ∼5 min and demonstrated a significant 225-fold reduction of Candida albicans adhesion over 6 days, compared to uncoated dentures. This rapid coating process could be applied to dentures and other dental devices chair-side and allow the research community to quickly and easily generate ominphobic surfaces.
