This note discusses the correction made by Sheridan to the formula used for predicting changes in fish size on the basis of selection differentials for a correlated trait [Canadian Journal of Fisheries and Aquatic Sciences (1996) 53 (4) 933]. It draws attention to the fact that, to predict the direc...

Necrotizing fasciitis is a rapidly spreading, bacterial, soft-tissue infection reported in both humans and dogs. A review of the pathophysiology, clinical findings, diagnosis, and treatment of necrotizing fasciitis is presented, with the goal of familiarizing veterinarians with this uncommon but pot...

The microsatellites, designated MN40-MN44, were isolated from subclones derived from a bacterial artificial chromosome (BAC) clone (145H12) by screening with a (GT)10 oligonucleotide probe. Polymerase chain reaction analysis of 19 unrelated animals revealed the presence of 4, 5, 10, 5 and 7 alleles ...

Carcinoma of the prostate is rare, and difficult to distinguish from hyperplasia, cysts and inflammation, except by histological examination of biopsy specimens. Details of 14 cases encountered at Pullman, Washington, between 1977 and 1983 are presented..

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...

The phenotypes with respect to congenital myasthenia gravis of 132 Smooth Fox Terrier dogs from 25 matings were analysed. These included both prospective and retrospective matings. It was determined that congenital myasthenia gravis in this breed is inherited in an autosomal recessive manner with co...

It is proposed that the wild-type xol-1 gene product of Caenorhabditis elegans promotes male development by ensuring that genes (or gene products) directing hermaphrodite sex determination and dosage compensation are inactive XO animals. In addition to feminizing XO animals, xol-1 mutations further ...

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...

Mast cell tumour, a common skin tumour of dogs, was treated effectively with radiation in 85 dogs. Prognosis for tumour-free and survival times were affected by several factors. Dogs with mast cell tumour of the extremities and dogs with clinical stage 0 (no gross evidence of disease), had significa...

An autosomal scan of the swine genome with 119 polymorphic microsatellite (ms) markers and data from 116 F2 barrows of the University of Illinois Meishan x Yorkshire Swine Resource Families identified genomic regions with effects on variance in carcass composition and meat quality at nominal signifi...

Three cases of disseminated feline blastomycosis occurred in Wisconsin and northern Illinois. Two had unilateral uveitis and retinal detachment and were treated successfully with a combination of surgery and chemotherapy with amphotericin-B and ketoconazole. Another with central nervous system signs...

Equine pituitary pars intermedia dysfunction (PPID) is a spontaneously occurring progressive disease affecting aged horses and ponies. The pathogenesis of PPID is poorly understood, but the available evidence supports a loss of dopaminergic inhibition of the melanotropes of the pars intermedia. Hors...

Using single-locus microsatellite markers, higher levels of genetic variation were resolved than previously reported for northern pike (Esox lucius). 14 (AC)n.(TG)n microsatellite loci were isolated from a genomic library of northern pike. Primer pairs for the polymerase chain reaction were develope...

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...

PCR primers that amplified 6 microsatellite loci in walleye were designed. The level of variation at these loci was examined in 186 adult walleye from Sioux Lake (Minnesota). The number of alleles per locus ranged from 4 to 10; the expected heterozygosity ranged from 0.4 to 0.78. Three of the 6 prim...

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 ...

Expression of the Caenorhabditis elegans Hox gene lin-39 begins in the embryo and continues in multiple larval cells, including the P cell lineages that generate ventral cord neurons (VCNs) and vulval precursor cells (VPCs). lin-39 is regulated by several factors and by Wnt and Ras signaling pathway...

Late events in the cell-cell signalling pathway that controls the specification of vulva cell fates in C. elegans are characterized. The lin-31 gene acts downstream of the ras homolog let-60 and encodes a member of the HNF-3/fork head family of DNA-binding transcription factors. lin-31 regulates how...

The microsatellites were isolated from horse genomic DNA using a (GT)10 probe. They had 11-22 copies of a GT-AC dinucleotide repeat. PCR amplification of DNA from 13 reference stallions of diverse breeds from the International Equine Genome Mapping Workshop showed the presence of 2-7 alleles at the ...

A genetic mosaic analysis procedure in which Caenorhabditis elegans mosaics are generated by spontaneous loss of an extrachromosomal array is described. This technique allows almost any C. elegans gene that can be used in germline transformation experiments to be used in mosaic analysis experiments....
