Environment and Behavior: Neurochemical Effects of Different Diets in the Calf Brain.

Calves reared for the production of white veal are subjected to stressful events due to the type of liquid diet they receive. Stress responses are mediated by three main stress-responsive cerebral regions: the prefrontal cortex, the paraventricular nucleus of the hypothalamus, and the nucleus of the solitary tract of the brainstem. In the present study, we have investigated the effects of different diets on these brain regions of ruminants using immunohistochemical methods.

Prospective evaluation of the acute patient physiologic and laboratory evaluation score and an extended clinicopathological profile in dogs with systemic inflammatory response syndrome.

Objective: To investigate the prognostic value of the acute patient physiologic and laboratory evaluation (APPLE) score and relevant clinicopathological markers in dogs with systemic inflammatory response syndrome (SIRS).

Design: Prospective observational cohort study.

Setting: Veterinary teaching hospital.

Response to Giannelli et al.--comments on potential efficacy of monthly administrations of spot-on moxidectin 2.5%/imidacloprid 10% in the simultaneous prevention of major canine filarioses.

Some comments have been done on an article describing a pilot trial evaluating the potential use of moxidectin contained in a spot-on formulation in the prevention of canine filarioses in a confined area where the three major canine filariae live in sympatry. We herein present our response to these comments.

Potential efficacy of monthly administrations of spot-on moxidectin 2.5%/imidacloprid 10% in the simultaneous prevention of major canine filarioses.

Dirofilaria immitis, Dirofilaria repens, and Acanthocheilonema reconditum are the most important canine filariae. These species are expanding their distribution in both endemic regions and in previously free areas, thus enhancing the risk for single and mixed infestations in both dogs and humans. The present study evaluated the potential use of moxidectin in a spot-on formulation in preventing these dog filarioses in a confined area where the three major canine filariae live in sympatry.

GeneScanning analysis of Ig/TCR gene rearrangements to detect clonality in canine lymphomas.

The diagnosis of canine lymphoma is achieved using morphological and immunological methods. In a certain percentage of cases, difficulties in making a definitive diagnosis of lymphoproliferative disorders may occur despite extensive immunophenotyping. Therefore, additional diagnostics, such as molecular assessment of Ig/TCR gene rearrangements clonality, may confirm the final diagnosis.

Prognostic value of serum vascular endothelial growth factor (VEGF) and plasma activity of matrix metalloproteinase (MMP) 2 and 9 in lymphoma-affected dogs.

Canine non-Hodgkin's lymphoma (NHL) is considered to be a good animal model for its human counterpart; nevertheless, comparative data on neo-angiogenesis are completely lacking. The aim of this study is to investigate the levels of serum vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) 2 and 9 in lymphoma-affected dogs. Circulating levels of VEGF and both MMP 2 and 9 activities significantly correlate with the WHO sub-stage b prognostic factor; moreover, VEGF at admission have an independent influence on the length of the disease free interval.

Validation of a human immunoturbidimetric assay to measure canine albumin in urine and cerebrospinal fluid.

The aim of this study was to validate an automated immunoturbidimetric assay used to quantify human albumin in urine and to accurately measure canine albumin concentrations in both urine and cerebrospinal fluid. The partial homology existing between human and canine albumin limited the accuracy of the human assays in measuring canine albumin without method modifications. Thus, the assay was modified by calibrating the analyzer with calibrators made in the laboratory containing known concentrations of canine albumin.
