Two invertebrate haemoglobins (Hb) from Ascaris suum and Lucina pectinata in which residues E7 and B10 are a glutamine and tyrosine, respectively, and which have high oxygen affinities stemming from slow ligand off rates were compared with respect to conformational and functional properties. Ultravi...

Conserving genetic diversity within and among populations of northern pike Esox lucius is important for maintaining their short-term fitness and long-term evolutionary potential. Northern pike have consistently shown low within-population variation, as detected by allozymes, mitochondrial DNA, and r...

OBJECTIVE: To evaluate concordance among veterinary pathologists in the assessment of histologic findings in the pars intermedia of pituitary gland sections from aged horses with mild signs suggestive of pituitary pars intermedia dysfunction (PPID). Sample Population-10 pituitary glands from aged ho...

Described are the first antemortem diagnosis made via fecal examination using the Baermann technique and the first postmortem recovery of endemic Angiostrongylus vasorum in dogs from North America, specifically the Avalon peninsula of Newfoundland. In one dog, A. vasorum was recovered and identified...

Calcinosis circumscripta associated with polydioxanone suture material was diagnosed in two young dogs. In each case, the owner noticed a firm mass at the site of a previous surgical incision. Mineralization of soft tissues was visible radiographically. At excision, multiple chalky white nodular mas...

Twenty-three smooth fox terriers with an inherited form of myasthenia gravis were studied. All dogs developed muscle weakness between 4 and 8 weeks of age. This weakness increased in severity with exercise and age. Muscle weakness was alleviated by the administration of a short acting cholinesterase...

A malignant neoplastic process originating from gall bladder epithelium was diagnosed in a 14-year-old, spayed female, domestic shorthair cat. The tumor produced widespread pulmonary and lymphatic metastases. The clinical and pathological manifestations are described. Neoplasia arising from the gall...

It has been shown previously that, in studies of hybrid populations there is a high probability of error in classifying individuals as parental, F1 or F2 on the basis of analysis of their genotypes. In the present work, the effects of the number of dominant loci examined on the probability of classi...

Clinical muscular and neurological signs are described for 13 Smooth Fox Terriers affected with a congenital form of myasthenia gravis. Treatment with a long-acting cholinesterase inhibitor in six cases resulted in temporary improvement in muscle strength. From examination of the phenotypes of 132 S...

Paired samples of formalin-fixed, paraffin-embedded ileum and lymph node from 204 culled dairy cows were investigated for evidence of infection by Mycobacterium avium subsp. paratuberculosis. Of the samples, 151 were from animals that were tissue-culture positive for M. avium subsp. paratuberculosis...

A study was conducted to compare the efficacy of sulbactam: ampicillin (SAMP) (3.3:6.6 mg/kg body weight (BW), IM, q24 h) to that of ampicillin trihydrate (AMP) (6 mg/kg BW, IM, q24 h) and 0.9% saline (SAL) (3 mL IM, q24 h) for the treatment of diarrhea in calves induced by oral inoculation with Esc...

The ethanol-induced conformation transition of regenerated B. mori silk fibroin membrane from a poorly defined to the well ordered state was monitored by time-resolved Fourier transform infrared spectroscopy (FTIR) for the first time. From the analysis of FTIR difference spectra, taken on time scale...

In 13 Smooth Fox Terriers with a congenital form of myasthenia gravis, clinical signs included intermittent, progressive muscle weakness that became more pronounced with exercise; muscle wasting; megaoesophagus; and aspiration pneumonia. Neurological abnormalities were apparent only during periods o...

The classes of 2007 from the Atlantic Veterinary College, Ontario Veterinary College, and Western College of Veterinary Medicine were surveyed to determine what factors influenced the respondents' career path choices. Seventy percent (166/237) of those contacted participated in the survey of which 8...

A 12-year-old intact female miniature Schnauzer dog with a history of depression, anorexia and weakness including one episode of collapse was examined. Past pertinent history included recent repeated bouts of vomiting and the passage of black loosely formed faeces. The dog was moderately dehydrated ...

Walleye, (Stizostedion vitreum), from two northern Minnesota, USA spawning stations (Pike River, Hudson Bay drainage, and Little Cutfoot Sioux Lake, Mississippi River drainage) simultaneously stocked as fry into five southern Minnesota lakes had different survival rates. One year after stocking, Pik...
