These results suggest that thymol and DIC were appreciably absorbed, degraded, or otherwise made unavailable in the proximal alimentary tract and that encapsulation technologies will likely be needed to deliver effective concentrations of these compounds to the lower gut to achieve in vivo reduction...

Our results provide strong evidence supporting the critical role of TLR3 and TLR21 in avian innate immunity against both viral and bacterial infections; and the synergistic interaction between the TLR3 and TLR21 pathways produces a stronger Th1-biased immune response in chicken monocytes. Our result...

We address how the CNS role has been conceptualized and studied in Canada. Because the CNS is a clinical leader with a primary focus on improving the quality of nursing and patient care, we propose the Spheres of Influence Model for studying the contributions of the CNS. This model directs attention...

We study animals rather than people and receive research approval from animal care rather than ethics committees. However, animal care evaluation forms are developed from concerns about laboratory animal research and are based on the "Three R's" for humane treatment of captive experimental subjects...

We increasingly find ourselves in complex situations where we must balance human and nonhuman primate needs and interests. The selection of commentary pieces in this edition of the American Journal of Primatology originated from presentations given in the symposium, Field Primatology of Today: Navig...

Summary Caribbean hair sheep are more resistant to gastrointestinal nematodes than conventional wool breeds, but mechanisms that confer resistance are not fully understood. This study compared immune effector cell populations and antibody concentrations in 12 hair and 12 wool lambs i...

We tested young degus in a potentiation paradigm to determine if social contact, particularly with the mother, can modulate an infant's vocal response to isolation. One week later, animals were presented with a choice between their mother and an unfamiliar female or a sample of familiar and unfamili...

Two research studies explored rural nurses' experience with the provision of maternity care in rural British Columbia, Canada. Frontline nurses, managers, and health-care providers were interviewed and their practices observed. One of the main challenges identified by rural nurses was ensuring that...

Our objective was to investigate differences in gene expression between 24 parasite-resistant hair and 24 susceptible wool lambs to determine genetic mechanisms involved in resistance to H. contortus. Half of the animals of each breed were infected and sacrificed at 3 or 27 days post-infection; the...

The scavenger receptors (SRs) comprise structurally and functionally divergent groups of cell surface and secreted proteins that play an important role in innate immune defenses. Searching translated chicken genomic databases revealed many proteins homologous to mammalian SRs. SR med...

We assessed these changes using real-time qRT-PCR to measure expression of TLR 1LA, 2A, 2B, 3, 4, 5, 7, 15, and 21 in the duodenum, jejunum, ileum, cecal tonsil, ceca, and large intestine of uninfected and SE-infected 2-day-old broiler chickens. Samples were collected soon after hatch to approximate...

We identified 100 scientific questions that, if answered, would have the greatest impact on conservation practice and policy. Representatives from 21 international organizations, regional sections and working groups of the Society for Conservation Biology, and 12 academics, from all continents excep...

We examined the effectiveness of CpG-ODN administered in ovo on intestinal colonization by SE and the ability to modulate the function of heterophils in young chickens. Heterophils were isolated from 2-day-old chickens and were stimulated with heat-killed SE (HK-SE) or PMA for oxidative burst and HK...

Our laboratory previously demonstrated a role for TLR function in the differential innate response of two lines of chickens to bacterial infections. The aim of the present study was to elucidate the role of TLRs in the differential innate responsiveness by measuring differences between lines A (resi...

We propose a conceptualization of social justice that is consistent with addressing the conditions that influence health inequities. We also discuss the implications of a critical and feminist conception of social justice for nursing action, education, practice, research, and policy....
