Transfer of Odor Perception From the Retronasal to the Orthonasal Pathway.

Although orthonasal odorants are often associated with the external environment, retronasal odorants are accompanied by consummatory behaviors and indicate an internal state of an animal. Our study aimed to examine whether the same odorants may generate a consistent perceptual experience when 2 olfactory routes potentiate variations in concentration in the nasal cavity and orosensory activation. A customized lick spout with vacuum removing odorants around the animal's nares was used to render a pure retronasal exposure experience.

Health Services in Boarding School: An Oasis of Care, Counseling, and Comfort.

Adolescents who attend high school as preparatory boarding students are growing up and learning to care for themselves in a very different set of circumstances than those who live at home with their families. Although this choice may present myriad opportunities for personal growth and academic advantages, nurturance and support from caring adults is necessary to foster health and well-being. Our model of a collaborative relationship between nursing and counseling in providing health services to the adolescents in our care at St.

Structural modifications of (Z)-3-(2-aminoethyl)-5-(4-ethoxybenzylidene)thiazolidine-2,4-dione that improve selectivity for inhibiting the proliferation of melanoma cells containing active ERK signaling.

We herein report on the pharmacophore determination of the ERK docking domain inhibitor (Z)-3-(2-aminoethyl)-5-(4-ethoxybenzylidene)thiazolidine-2,4-dione, which has led to the discovery of compounds with greater selectivities for inhibiting the proliferation of melanoma cells containing active ERK signaling.

Association of medically attended traumatic brain injury and in-prison behavioral infractions: a statewide longitudinal study.

This study examined the association between medically attended traumatic brain injury (TBI) and in-prison behavioral infractions in a statewide population by comparing rate ratios of infractions in inmates with and without TBI over an 11.5-year period (16,299 males and 1,270 females). The in-prison behavioral infraction rate was significantly increased in males with TBI compared with no TBI for all infractions (RR = 1.

The other branch of medicine: an historiography of veterinary medicine from a Canadian perspective.

Animal (veterinary) medicine, that other branch of medical healing, forms a part of medical history and there are themes in common between human and veterinary medical historiography. Some of these themes include "great docs, great diseases," struggles with professionalization, institutional stories, general chronological overviews, development of medical disciplines, and the role of women. The "patient's view" in veterinary historiography is somewhat different.

A comparison of gross pathology, histopathology, and mycobacterial culture for the diagnosis of tuberculosis in elk (Cervus elaphus).

Using the isolation of Mycobacterium bovis as the reference standard, this study evaluated the sensitivity, specificity and kappa statistic of gross pathology (abattoir postmortem inspection), histopathology, and parallel or series combinations of the two for the diagnosis of tuberculosis in 430 elk and red deer. Two histopathology interpretations were evaluated: histopathology I, where the presence of lesions compatible with tuberculosis was considered positive, and histopathology II, where lesions compatible with tuberculosis or a select group of additional possible diagnoses were considered positive. In the 73 animals from which M.

"Mappings of secrecy and disclosure": The Swimming Pool Library, the closet, and the empire.

The Swimming Pool Library is a novel of the closet that also offers a post-colonial reading of homosexuality in contemporary culture. Through its interpretation of gay life as a dialogic between Wildean and Gidean readings of homosexuality, and its examination of the closet as what Sedgwick calls "the defining structure of gay oppression," the novel analyzes the tensions of political oppression against sexual freedom. The Swimming Pool Library is thus seen as a text in conflict with itself about the very issues it raises: closeting and gay liberation, sexual freedom and sexual responsibility, loyalty to the past and duty in the present.

Classification of 1,198 cases of bovine lymphoma using the National Cancer Institute Working Formulation for human non-Hodgkin's lymphomas.

A retrospective histologic study was made of 1,198 cases of bovine lymphoma using the National Cancer Institute Working Formulation for human non-Hodgkin's lymphoma. This classification scheme was found to be readily applicable to bovine lymphoma. Most of the cell types described in the National Cancer Institute Working Formulation occurred in this series of bovine lymphomas, but the distribution of cell types varied markedly compared to that of human beings.

Paratuberculosis in saiga antelope (Saiga tatarica) and experimental transmission to domestic sheep.

Mycobacterium paratuberculosis was isolated in low numbers from the small intestine and associated mesenteric lymph nodes of a saiga antelope (Saiga tatarica) using routine culture techniques in spite of histologic evidence of high numbers of acid-fast bacteria in these tissues. Two newborn domestic sheep were fed the ground intestinal tissue containing acid-fast bacteria and the progression of the experimental disease was followed by fecal culture, immunodiffusion (AGID) and lymphocyte stimulation (LST) tests. One experimentally infected sheep developed progressive clinical illness 1 yr postinoculation.

A hundred years of importation: The first animal quarantine station in North America; Lévis, Québec, 1876-1982.

Quarantine, as a means of preventing disease importation, has been used for people and animals since the mid-19th century in Canada. The first animal quarantine facility in North America was established at Lévis, Québec in 1876. This quarantine station existed at Lévis until 1982 when it was closed and the function moved to Mirabel, Québec, near the International Airport.

An abattoir survey of urinary bladder lesions in cattle.

Postmortem examination of 21,340 cattle at an Ontario abattoir over a one-year period revealed macroscopic lesions in urinary bladders of 2,296 animals (10.8%). Chronic cystitis, the most frequent finding, was observed in 2,209 cases (10.

Protein G-based enzyme-linked immunosorbent assay for anti-MPB70 antibodies in bovine tuberculosis.

MPB70 is a highly species specific protein which is secreted from Mycobacterium bovis during culture. To investigate whether antibodies against MPB70 can be used as an indicator of infection with M. bovis, an enzyme-linked immunosorbent assay was developed, based on the use of biotinylated protein G, to provide a common indicator for antibody formation in different species.
