canis. Higher values of ALT were observed in the group infected with Leishmania sp. and in co-infections with concurrent increase of AST and alkaline phosphatase. Significant differences were observed between dogs infected by Ehrlichia canis and Anaplasma platys, whereas animals

infected by E. canis demonstrated lower values for albumin (P smaller than 0,02), and higher ALT (P smaller than selleck 0,05) and alkaline phosphatase (P smaller than 0,02). Discussion: Renal azotemia, as a result of glomerulonephritis and interstitial nephritis is extensively described in dogs with leishmaniasis, but may also occur in cases of ehrlichiosis, as evidenced in this study. Changes in serum albumin and globulin are frequent in hemoparasitoses, especially in the leishmaniasis and chronic phase of ehrlichiosis, as observed in this study. Changes in biochemical analytes were frequent in animals with hemoparasitoses, highlighting the values of urea and creatinine in dogs with leishmaniasis, that also presented decreased levels of albumin and increased levels of globulins. Although these findings are reported in dogs with anaplasmosis, hipoalbiminemia selleck compound and hypergammaglobulinemia were not identified in animals infected only by A. platys in this study. The hypoalbuminemia occurs

as a consequence of decreased protein intake caused Ulixertinib price by anorexia, decreased protein production due to liver damage or loss in urine due to the kidney damage (proteinuria) while hyperglobulinaemia is linked to the host’s immune response against the parasite, exacerbated in co-infections, as identified in this study. Hepatocellular damage was demonstrated by increased values of alkaline phosphatase and alanine aminotransferase (ALT) in animals infected with Ehrlichia canis. Statistical differences allowed to infer higher pathogenicity of Ehrlichia canis despite Anaplasma platys, especially in relation to oxidative stress and

hepatocellular injury, although the differences may be also attributable to the stage of the disease the dogs were in.”
“Aims/hypothesis Cytokine-induced apoptosis is recognised as a major cause of the decline in beta-cell mass that ultimately leads to type 1 diabetes mellitus. Interleukin-1 beta, interferon-gamma and tumour necrosis factor-alpha in conjunction initiate a series of events that lead to beta-cell apoptosis; important among these is NO production. The glycosphingolipid sulfatide is present in beta-cells in the secretory granules in varying amounts and is secreted together with insulin. We now investigate whether sulfatide is able to protect insulin-producing cells against the pro-apoptotic effect of interleukin-1 beta, interferon-gamma and tumour necrosis factor-alpha.
