The effects and interaction between cAMP-analogue dibutyryl-cAMP and calmodulin antagonists were investigated on de novo synthesis and secretion of lipids in cultures of hepatoma McArdle-RH7777 cells and normal rat hepatocytes. Dibutyryl cAMP caused a significant decrease in the secretion of de novo synthesized triacyl [3H] glycerol in both cultures of McArdle cells and rat hepatocytes. The ...

Fire blight, which is a major constraint to pome fruit production in many areas of the world, is most commonly initiated by epiphytic populations of Erwinia amylovora that develop on blossoms (1,26). Under relatively dry climatic conditions, bacteria colonize flower stigmas, and subsequent rain or heavy dew facilitates movement to the floral cup (hypanthium), where infection generally occurs (2...

Exploitation of the metabolic capabilities of the genus Sphingomonas could provide important commercial benefits to biotechnology. Recent advances have demonstrated that these organisms have unique abilities to degrade refractory contaminants, to serve as bacterial antagonists to phytopathogenic fungi, and to secrete the highly useful gellan exopolysaccharides. Unfortunately, Sphingomonas are a...

Introduction: Renal ischemia-reperfusion (RIR) may disturb renin-angiotensin system components. In this study, the effects of Mas receptor (A779) and AT2 receptor (PD123319) antagonists were examined in RIR rats. Methods: Total 60 male and female Wistar rats were assigned into 10 groups (n=6 in each group), including sham-operated group, RIR groups treated with the vehicle, A779, PD123319, ...
