We detected Leishmania mexicana in skin biopsies taken from a stray canine (Canis familiaris) and Texas mouse (Peromyscus attwateri) at two ecologically disparate sites in west and central Texas using polymerase chain reaction (PCR). A single PCR-positive dog was identified from a sample of 96 stray canines and was collected in a peri-urban area in El Paso County, Texas. The PCR-positive P. attwateri was trapped at a wildlife reserve in Mason County, Texas, from a convenience sample of 20 sylvatic mammals of different species...

Computed tomography (CT) continues to become more widely available for assessment of tumors in dogs, yet there are no studies describing the CT appearance of canine liposarcomas. In this retrospective, multicenter study, CT images of dogs with histologically confirmed liposarcomas were reviewed for size, location, attenuation, contrast enhancement, border definition, internal homogeneity, local infiltration, and mineralization. A total of 24 dogs with 26 liposarcomas were sampled. Mean attenuation was +15.2 (SD = 22...

Ultrasonographic evaluation of the adrenal glands was performed in 85 dogs, followed by macroscopic and histopathological examination either post-mortem or after adrenalectomy. This retrospective cross-sectional study evaluated the difference between gross and ultrasonographic measurements to determine the diagnostic accuracy of ultrasonography in the evaluation of canine adrenal gland size. The differences were assessed for gland length, thickness at cranial, middle and caudal regions, and surface area. In our sample, ultrasound error accuracy ranged between 0% in measurement of the right adrenal gland surface area and 25...

Canine Influenza Virus (CIV) H3N8 is the causative agent of canine influenza, a common and contagious respiratory disease of dogs. Currently, only inactivated influenza vaccines (IIVs) are available for the prevention of CIV H3N8. However, live-attenuated influenza vaccines (LAIVs) are known to provide better immunogenicity and protection efficacy than IIVs. Influenza NS1 is a virulence factor that offers an attractive target for the preparation of attenuated viruses as LAIVs. Here we generated recombinant H3N8 CIVs containing truncated or a deleted NS1 protein to test their potential as LAIVs...

American badgers ( Taxidea taxus jacksoni) at the periphery of the species' range in Ontario, Canada, are listed as endangered because of an estimated population size of <200 mature individuals. The main threats faced by this population include habitat loss and road mortality. However, on 18 November 2013, a radio-implanted badger was found nonresponsive in an agricultural field with signs consistent with canine distemper virus infection, which was subsequently confirmed. This prompted our investigation into the occurrence of pathogens in this endangered carnivore to better quantify the level of risk infectious disease poses to population persistence...

BACKGROUND: The major challenge for developing gene-based therapies for hemophilia A is that human factor VIII (hFVIII) has intrinsic properties that result in inefficient biosynthesis. During intracellular processing, hFVIII is predominantly cleaved at a Paired basic Amino acid Cleaving Enzyme (PACE) or furin cleavage site to yield a heterodimer that is the major form of secreted protein. Previous studies with B-domain deleted (BDD) canine FVIII and hFVIII-R1645H, both differing from hFVIII by a single amino acid at this site, suggested that these proteins are secreted mainly in a single polypeptide chain (SC) form and exhibit enhanced function...

The Warburg effect describes the ability of cancer cells to produce energy via aerobic glycolysis instead of oxidative phosphorylation of pyruvate. This deviation in mitochondrial metabolism inhibits apoptosis, allowing increased proliferation under conditions of reduced oxygen levels. Dichloroacetate (DCA) was successfully used in several human cancer cell lines to reactivate oxidative phosphorylation in mitochondria. The aim of this study was the characterization and response of canine cancer cell lines after DCA exposure...

Radiation therapy of the head and neck can result in mucositis and other acute affects in the oral cavity. This prospective pilot study evaluated a novel, intraoral, beam-blocking device for use during imaging and therapeutic procedures. The beam-blocking device was made from a metal alloy inserted into a coated frozen dessert mold (Popsicle® Mold, Cost Plus World Market, Oakland, CA). The device was designed so that it could be inserted into an outer shell, which in turn allowed it to be placed or removed depending on the need due to beam configuration...

Lafora disease is a fatal genetic disorder characterised by neurotoxic deposits of malformed insoluble glycogen. In humans it is caused by mutation in the EPM2A or NHLRC1 genes. There is a known mutation in miniature wirehaired dachshunds which has not been documented in other dog breeds, including beagles, in which the disease is relatively commonly reported. This case report describes the causative defect in two affected beagles, namely the same massive expansion as in miniature wirehaired dachshunds of a 12-nucleotide repeat sequence that is unique to the canine NHLRC1 gene...

Single immediate implant replacement is accompanied by excellent survival rates and a favorable esthetic outcome. The objective of this report was to describe a surgical approach for removal of a buccal or palatally located impacted secondary canine, combined with extraction of the failing primary canine, and immediate placement and provisionalization of an implant. A window technique was applied for surgical removal of the impacted canine. The alveolar crest was preserved. After extraction of the primary canine, the implant was inserted with primary stability...

Measurements of the root canal during endodontic treatment have a significant influence on the course of the therapeutic process as well as on its final result in both human and veterinary medicine. The apical constriction should be the termination point for the preparation and filling of the root canal. This research was conducted with the use of a Septodont kit consisting of a small chamber filled with the examined solution in which a healthy second incisor was placed. The step back method was applied for the root canal preparation and master apical file of 30 was used...

Serum biomarkers of canine lymphoma activity for diagnosis, prognosis, and therapy monitoring have been of clinical interest for more than a decade. Tumor products, biochemical enzymes, cytokines, metabolic profiling, leakage enzymes, as well as serum proteins have been studied as biomarkers for lymphoma. Multiple biomarkers combined have been shown to be most sensitive and specific. C-reactive protein, thymidine kinase 1, and haptoglobin have been most extensively studied and commercialized in diagnostic tests, the TK Canine Cancer Panel and the Canine Lymphoma Blood Test...

STATEMENT OF PROBLEM: When reconstructing the occlusal curvatures dentists often use a 4-inch radii arc as a rough standard based on Monson spherical theory. The use of an identical radius for the curve of Spee for all patients may not be appropriate because each patient is individually different. The validity of application of this theory in the Indian population and the present study has been undertaken. AIMS AND OBJECTIVES: This study is an attempt to evaluate the curve of Spee and curve of Wilson in young Indian population using three dimensional analysis...

Understanding the molecular mechanisms of DNA double-strand break (DSB) repair processes, especially nonhomologous DNA-end joining (NHEJ), is critical for developing next-generation radiotherapies and chemotherapeutics for human and animal cancers. The localization, protein-protein interactions and post-translational modifications of core NHEJ factors, such as human Ku70 and Ku80, might play critical roles in controlling NHEJ activity. XRCC4-like factor (XLF) is a core NHEJ factor and plays a key role in the Ku-dependent NHEJ repair process in human cells...

Canine distemper virus (CDV) is one of the most serious pathogens found in many species of carnivores, including domestic dogs. In this study, hemagglutinin (H) genes were detected in five domestic Vietnamese dogs with diarrhea, and two CDVs were successfully isolated from dogs positive for H genes. The complete genome of one isolate, CDV/dog/HCM/33/140816, was determined. Phylogenetic analysis showed that all Vietnamese CDVs belonged to the Asia-1 genotype. In addition, the H proteins of Vietnamese CDV strains were the most homologous to those of Chinese CDVs (98...

The Stepwise Approach towards Rabies Elimination (SARE) tool was developed through a joint effort of the Food and Agriculture Organization (FAO) of the United Nations and the Global Alliance for Rabies Control (GARC), to provide a standard mechanism for countries to assess their rabies situation and measure progress in eliminating the disease. Because the African continent has the highest per capita death rate from rabies, and Ethiopia is estimated to have the second largest number of rabies deaths of all African countries, Ethiopia undertook a self-assessment by means of the Stepwise Approach towards Rabies Elimination (SARE) tool...
