Poststimulation catecholamine synthesis and tyrosine hydroxylase activation in central noradrenergic neurons. II. Depolarized hippoc...
The ability of neuronal depolarization to increase catecholamine biosynthesis in the poststimulation period was investigated in a preparation of central...
Evidence and cellular localization of an oxidative activity in the coelomic fluid of the earthworm
An oxidative activity was evidenced in the coelomic fluid of the earthworm Eisenia fetida andrei, when l-DOPA was used as substrate. Oxidative activity,...
Long-term neuroadaptations produced by withdrawal from repeated cocaine treatment: role of dopaminergic receptors in modulating cort...
Dopamine (DA) modulates neuronal activity in the prefrontal cortex (PFC) and is necessary for optimal cognitive function. Dopamine transmission in the P...
Differential effects of metal ligands on synaptic membrane glutamate binding and uptake systems
The high affinity, Na + -independent l -[ 3 H]glutamate binding process in synaptic membranes and in the purified binding protein was shown to be inhibi...
Nitrogen-doped carbon nanotube/polyaniline composite: Synthesis, characterization, and its application to the detection of dopamine
Nitrogen-doped carbon nanotubes (N-CNTs)/polyaniline (PANI) composites are developed as an electrode material for biosensors. The morphology, compositio...
Synthesis of l-Tyrosine or 3,4-Dihydroxyphenyl-l-alanine from Pyruvic Acid, Ammonia and Phenol or Pyrocatechol
The synthesis of l-tyrosine or 3,4-dihydroxyphenyl-l-alanine (l-dopa) from pyruvate, ammonia and phenol or pyrocatechol was studied with intact cells of...
Effect of Gamama Radiation on Phenoloxidase Activity in Mediterranean Fruit Fly (Diptera: Tephritidae) Larvae
The effect of gamma radiation on the phenoloxidase activity in larvae of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), was examined. Phen...
Optical activity in Tb(III) mixed-ligand complexes containing pyridine-2,6-dicarboxylic acid and hydroxyphenyl derivatives
Addition of hydroxyphenyl derivatives to tris(dipicolinate)Tb(III) results in the generation of optical activity within the Tb(III) spectroscopic transi...
