The concentrations of endogenous amino acids and choline in the extracellular fluid of human cerebral gliomas have been measured, for the first time, by in vivo microdialysis. Glioblastoma growth was associated with increased concentrations of choline, GABA, isoleucine, leucine, lysine, phenylalanine, taurine, tyrosine, and valine. There was no difference(More)
Sodium terephthalate was shown to be a new robust and sensitive chemical trap for highly reactive oxygen species (hROS), which lacks the drawbacks of the salicylic acid method. Reaction of the almost non-fluorescent terephthalate (TA2-) with hydroxyl radicals or ferryl-oxo species resulted in the stoichiometric formation of the brilliant fluorophor,(More)
Activation of the caspase proteases represents a central point in apoptosis. The requirement for spermine for the processes leading to caspase activation has been studied in transformed embryonic fibroblasts obtained from gyro (Gy) mutant male mice. These cells lack spermine synthase activity and thus provide a valuable model to study the role of spermine(More)
OBJECTIVE We have recently shown that tumor necrosis factor-alpha (TNFalpha) and lipopolysaccharide (LPS) stimulate DNA synthesis in chick embryo cardiomyocytes (CMs). The aim of the present research was to investigate the pathways involved in this mitogenic response. METHODS CMs were isolated from 10-day-old chick embryos and grown to confluence. After(More)
Male rat chemosignals attract females and influence their reproductive status. Through the accessory olfactory bulb and its projection target, the posteromedial cortical nucleus of the amygdala (PMCo), species-specific chemosignals detected by the vomeronasal organ (VNO) may reach the hypothalamus. To test this hypothesis in vivo, behavioural activation and(More)
