the present study was carried out to determine whether helicobacter spp. infection in dogs could affect lesions caused by the non-steroidal anti-inflammatory drugs (nsaids), aspirin and celecoxib. thirty asymptomatic mixed-breed dogs were used for this study. gastric biopsies were taken via gastroscopy and evaluated by polymerase chain reaction (pcr) and rapid urease tests (rut). helicobacter s...

a one-month-old male terrier dog was referred in shock status with a history of anorexia, tachypnea, abdominal distention and progressive weight loss. auscultation of right side of the lungs found enhanced respiratory noises. the thorough auscultation of the opposite side of the chest revealed the presence of typical intestinal sounds. cardiac auscultation revealed muffled heart sounds and a di...

background: the aim was to study the gastro-intestinal helminths of stray dogs of garmsar, sem­nan province, central iran, and its impacts on human health and animal production. methods : during 2006, the alimentary tracts of 50 stray dogs at necropsy, selected from villages around garmsar, were removed, and examined for helminth infections. subsequently helminths were collected from the conten...

Stephen Schiffer 2003 presents six arguments against the Fregean model of propositions, according to which propositions are (a) the referents of that-clauses and (b) structured entities made out of concepts. Schiffer advances an alternative view: propositions are unstructured pleonastic entities. My purpose is to argue in favour of the main tenets of the Fregean model by countering each of Schi...

A dog with persistent elliptocytosis was studied. The dog had membrane protein band 4.1 deficiency, microcytosis, shortened erythrocyte lifespan, increased osmotic sensitivity, and a mild glutathione deficiency. Erythrocyte deformability and membrane stability were adversely effected. The dog's parents had decreased band 4.1, decreased stability, and some elliptocytosis. This disorder in dogs c...

The Animal Models for Protecting Ischemic Myocardium Study was undertaken for the purpose of developing reproducible animal models that could be used to assess interventions designed to limit infarct size. This paper describes the results obtained in an unconscious dog model and in a conscious dog model, developed in three participating laboratories. The unconscious dog model, involving reperfu...

Purpose: To assess the suitability of beagle dog as an animal model for the evaluation of formulations in bioavailability and bioequivalence studies. Methods: A generic cetirizine 10 mg tablet formulation was compared with another reference formulation using beagle dog as animal model. A crossover oral comparative bioavailability study was conducted on cetirizine tablet 10 mg in healthy, male d...

six mixed-breed apparently healthy dogs were intravenously administered a single dose of tetracycline hydrochloride (50 mg/kg) to evaluate the pharmacokinetic parameters of the drug. blood samples were collected before and at various time intervals after the administration of the drug. serum tetracycline concentrations were determined over a 24 h period using fluorescence spectrophotometry. non...

this study represents an unusual case of mucormycosis localized in nasal cavity of a german shepherd dog. the patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. the dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. initial nasal rhinoscopy showed s...

Understanding how the retina encodes visual information is a key issue for the development of a retinal prosthesis. To study this issue, the neural retina is modeled as a retina module (RM) consisted of an ensemble of spatialtemporal (ST) filters and each ST filter simulates the input-output property of an individual ganglion cell (GC). Two receptive field (RF) models of retinal GC, the differe...
