Detection of the T1640C mutation indicating malignant hyperthermia in dogs.

Malignant hyperthermia (MH) is a clinical syndrome exhibiting elevation of expired carbon dioxide, hyperthermia, muscle rigidity, rhabdomyolysis, acidosis and hyperkalaemia, as well as cardiac dysrhythmia and renal failure. The syndrome manifests itself as a response to anaesthetic agents, such as e.g.

Study of the Methylation of Bovine GSTP1 Gene under the Influence of Pesticide Mospilan 20SP Alone and in Combination with Pesticide Orius 25EW.

DNA methylation, one of the most studied epigenetic mechanisms, when present in the promoter region of genes, causes inhibition of gene expression, and conversely, hypomethylation of these regions enables gene expression. DNA methylation is susceptible to nutritional and environmental influences, and undesirable alterations in methylation patterns manifested in changes in the expression of relevant genes can lead to pathological consequences. In the present work, we studied the methylation status of the bovine GSTP1 gene under the influence of pesticide Mospilan 20SP alone and in combination with pesticide Orius 25EW in in vitro proliferating bovine lymphocytes.

Evaluation of , and Gene Methylation in Bovine Lymphocytes Cultured In Vitro with Miconazole Alone and in Combination with Mospilan 20SP.

5-methylcytosine (5mC) is one of the most important epigenetic modifications. Its increased occurrence in regulatory sequences of genes, such as promoters and enhancers, is associated with the inhibition of their expression. Methylation patterns are not stable but are sensitive to factors such as the environment, diet, and age.

In vitro evaluation of zearalenone toxicity by comet assay.

The aim of this study was to reveal the potentially genotoxic effect of zearalenone on bovine lymphocytes by comet assay in vitro. The bovine lymphocytes were exposed to various zearalenone concetrations (50; 10; 2; 0.4 and 0.

The adverse effects of synthetic acaricide tau-fluvalinate (tech.) on winter adult honey bees.

Currently several pyrethroids (e.g., flumethrin and tau-fluvalinate) are used in apiculture worldwide as acaricides/miticides.
