Emotion regulation strategy correlates with discrete state emotion in major depression.

Background And Objectives: Research has shown that state emotion can affect emotion regulation strategies in healthy samples. Emotion regulation plays an important role in depression. We hypothesized that for depressed individuals, experiencing anxiety or anger affects emotion regulation strategy use differently than experiencing sadness.

Immunohistochemical Features of Epithelial-Mesenchymal Transition in Feline Oral Squamous Cell Carcinoma.

Feline oral squamous cell carcinoma (FOSCC) is an aggressive malignancy with invasive and metastatic behavior. It is poorly responsive to chemotherapy and radiation. Neoplastic epithelial-mesenchymal transition (EMT) portends highly malignant behavior and enhances resistance to therapy.

Dasatinib Modulates Invasive and Migratory Properties of Canine Osteosarcoma and has Therapeutic Potential in Affected Dogs.

Background: This investigation sought to elucidate the relationship between hepatocyte growth factor (HGF)-induced metastatic behavior and the tyrosine kinase inhibitors (TKIs) crizotinib and dasatinib in canine osteosarcoma (OS). Preliminary evidence of an apparent clinical benefit from adjuvant therapy with dasatinib in four dogs is described.

Methods: The inhibitors were assessed for their ability to block phosphorylation of MET; reduce HGF-induced production of matrix metalloproteinase (MMP); and prevent invasion, migration, and cell viability in canine OS cell lines.

Comparative anatomy, physiology, and mechanisms of disease production of the esophagus, stomach, and small intestine.

The alimentary system may be thought of as an open-ended tube within a tube that begins at the oral cavity and ends at the anus. Gastrointestinal lumens are potential spaces that accommodate ingested substances and are lined by polarized epithelium that is smooth and shiny (with the exception of the rumen) when healthy and intact. Because xenobiotics most frequently enter the body via ingestion, the gastrointestinal system and its ancillary glands are the first line of defense against foreign materials and pathogens of all types.

A comparison of microscopic ink characteristics of 35 commercially available surgical margin inks.

Objective: To compare microscopic characteristics of commercially available surgical margin inks used for surgical pathology specimens.

Study Design: Prospective in vitro study.

Sample Population: Thirty-five different surgical margin inks (black, blue, green, orange, red, violet, and yellow from 5 different manufacturers).

Temporal and geographic clustering of polyomavirus-associated olfactory tumors in 10 free-ranging raccoons (Procyon lotor).

Reports of primary nervous system tumors in wild raccoons are extremely rare. Olfactory tumors were diagnosed postmortem in 9 free-ranging raccoons from 4 contiguous counties in California and 1 raccoon from Oregon within a 26-month period between 2010 and 2012. We describe the geographic and temporal features of these 10 cases, including the laboratory diagnostic investigations and the neuropathologic, immunohistochemical, and ultrastructural characteristics of these tumors in the affected animals.

Sudden behavior change in a cat.

A 5-year-old, spayed female, domestic short-haired cat had a 10-day history of sudden behavioral changes followed by seizures. Blood parameters were in the reference ranges, and radiographs failed to detect a mass lesion in the brain. Euthanasia was followed by rabies testing, which was negative.

Diagnostic exercise: Multiple skin nodules in a cat.

A 10-year-old, neutered, male, domestic short-haired cat had numerous, small, firm, round, red, nonpruritic, nonpainful, dermal nodules 5-16 mm in diameter that ruptured within 48 hours of their appearance and subsequently crusted over. The masses were located in all regions of the body. One mass was excised from the dorsal right carpus and examined histologically, and 2 masses from the interscapular region were cultured for bacteria.

Lymphadenopathy associated with a thyroid carcinoma in a dog.

Angiomatoid lesions in a lymph node associated with a thyroid carcinoma of a dog were restricted to the subcapsular and medullary sinuses. Lymphoid atrophy was present, but nodal architecture was not distorted and normal structures were not invaded. Immunohistochemical staining indicated that the vascular spaces formed by spindloid cells were lined by endothelium with a low mitotic index.

Neurologic disease in a pig.

Three 4-week-old Yorkshire-Hampshire cross piglets from a litter of 9 (7 liveborn) developed convulsions the day of weaning. They were subsequently obtunded, ataxic, and hypermetric and had intention tremors. An affected male pig was presented live for necropsy on day 5 postweaning.

Urinary bladder mass in a dog.

A 7-year-old spayed female Schnauzer dog with chronic hematuria had a soft tissue mass within the wall of the bladder. The mass was excised and, when examined histologically, was determined to be a discrete well-organized mural mass consisting of spindloid cells arranged in swirling sheets and palisades punctuated by aggregates of principally eosinophils. The overlying transitional mucosa was extensively ulcerated and focally hyperplastic and nodular with subjacent solid down growths, superficial cysts, and the extension of tubular structures deep into the submucosa.

Purkinje fiber dysplasia (histiocytoid cardiomyopathy) with ventricular noncompaction in a savannah kitten.

In a 2-month-old female savannah kitten that died unexpectedly, the pathologic findings of significance were restricted to the heart and included abnormal Purkinje fibers and biventricular myocardial trabeculation or noncompaction. The Purkinje fibers were large, angular, and tightly packed. They contained few disorganized myofibrils among a rarified cytoplasm.

Listeria associated mural and valvular endocarditis in an alpaca.

An alpaca presented for emergency evaluation of respiratory distress. Physical examination revealed weakness, pyrexia, and a grade V/VI left apical holosystolic murmur. Initial thoracic examination and radiographs were consistent with left sided congestive heart failure.

Native American tribal cultures: implications for veterinary medical education.

This article reviews the literature from veterinary medicine, tribal education, career development, and psychology to focus on the reasons that Native people are currently under-represented in the field of veterinary medicine. Educational implications and recruitment strategies are suggested. Local, state, and national resources are provided to help veterinary medical educators make their programs more culturally competent for Native veterinary students and faculty.

Stress management interventions for veterinary students.

Two-hundred-and-eighty-nine veterinary students from all four years of the University of Tennessee, College of Veterinary Medicine (UTCVM) were invited to complete the Derogatis Stress Profile (DSP)1 and an original Demographic Data Profile (DDP). The DSP assessed the students' current experiences of perceived stress, and the DDP was designed to gather information about students' academic year, their living situations, their financial situations, their interest area within the veterinary medical profession, and their current methods of coping with stress. These data were gathered as a baseline measure of veterinary medical students' perceived level of stress and quality of life.

Microbial adhesion of Cryptosporidium parvum sporozoites: purification of an inhibitory lipid from bovine mucosa.

Cryptosporidium parvum is a protozoan pathogen of humans and livestock worldwide. Its ability to infect a wide range of species raises questions as to the involvement of a specific host cell receptor for parasite-host recognition. To investigate the mechanism of parasite-host cell recognition, we have developed an in vitro cell suspension binding assay to investigate adhesion of C.

Perspectives on academic veterinary administration.

It is important for veterinary administrators to apply knowledge bases from other fields to their own unique administrative needs. For example, although some resources are written for business managers, the discussions of four key management competency areas, guidelines for mastering these skills, organizational assessment tools, and other self-help tools may provide interesting food-for-thought for veterinary administrators.(76) In developing their own administrative styles, administrators should seek to apply those principles that seem to intuitively fit with their personal research styles, work situations, managerial styles, administrative preferences, and unique organizational culture.

Endocardial ossifying myxoma of the right atrium in a cat.

Primary cardiac neoplasms are rare in humans and animals. In humans, the most common primary cardiac tumor is the myxoma, which is frequently found in the left atrium. Cardiac myxoma has been reported in the dog but not in the cat.

Sialic acid dependence and independence of group A rotaviruses.

We have found (1), in contrast to previous reports, the human rotavirus Wa strain is sialic acid-dependent for binding to and infectivity of MA-104 cells and (2), a dual carbohydrate binding specificity is associated with both human Wa and Porcine OSU rotaviruses. One carbohydrate binding activity is associated with triple-layered virus particles (TLP) and the other with double-layered virus particles (DLP). In binding and infectivity studies, we found that gangliosides were the most potent inhibitors of both the human and procine rotavirus TLP.
