Neutering is associated with developing hemangiosarcoma in dogs in the Veterinary Medical Database: An age and time-period matched case-control study (1964-2003).

The hypothesis that neutered dogs in the Veterinary Medical Database (VMDB) are at increased risk for developing hemangiosarcoma (HSA) was tested. Dogs ( = 5736) were diagnosed with HSA from a population of 2 106 324 dogs in the VMDB from 1964 to 2003. A case-control design matched on age and time period was created for general, cardiac, and splenic HSAs.

Differential Modulation of Transcription Factors and Cytoskeletal Proteins in Prostate Carcinoma Cells by a Bacterial Lactone.

The present study tested the effect of a bacterial lactone N-(3-oxododecanoyl)-homoserine lactone (C12-HSL) on the cytoskeletal and transcriptional genes and proteins in prostate adenocarcinoma (PA) cells (DU145 and LNCaP) and prostate small cell neuroendocrine carcinoma (SCNC) PC3 cells including their cellular viability and apoptosis. Our data indicate that cell migration and colony formation were affected in the presence of C12-HSL. C12-HSL induced apoptosis and altered viability of both PA and SCNC cells in a concentration dependent manner as measured by fluorescence and chemiluminescence assays.

Use of an electronic brachytherapy surface applicator to treat an epiglottal fibrosarcoma in a dog.

Presented is the case of an epiglottal fibrosarcoma in a dog. The location of the mass resulted in challenges in the delivery of adequate dose to the tumor, and herein we describe the treatment using an electronic brachytherapy source. The treatment consisted of four Gy fractions, twice daily for a total of 10 fractions (40 Gy total).

The impact of oral versus inhaled glucocorticoids on allergen specific IgE testing in experimentally asthmatic cats.

Glucocorticoids (GCs) are palliative for allergic asthma, but allergen-specific immunotherapy (ASIT), which relies on identification of allergens, represents a potentially curative treatment. The purpose of this study was to determine if oral or inhaled GCs would interfere with identification of sensitizing allergens. The hypothesis was that oral but not inhaled GCs would interfere with accurate allergen-specific IgE identification determined by skin and serum testing in experimentally asthmatic cats.

Renal graft rejection after allogeneic peripheral-blood stem cell transplantation.

A 28-year-old woman underwent peripheral-blood stem cell transplantation from her HLA-identical sister for cytogenetic progression of Fanconi anemia. She had received a living-related renal allograft from her father 2 years previously. Nine days after peripheral-blood stem cell transplantation, she developed acute renal failure secondary to acute rejection.
