Obstruction of Water Uptake in cut Chrysanthemum Stems after Dry Storage: Role of Wound-induced Increase in Enzyme Activities and Air Emboli [PDF]

open access: yes, 2009
Hydraulic conductance of cut chrysanthemum stems was lowered by the aspiration of air as well as by a wound-induced plant response. By measuring the hydraulic conductance of stem segments in which air could be introduced into and/or removed from the ...

Cholinergic modulation of dopamine overflow in the rat neostriatum: A fast cyclic voltammetric study in vitro [PDF]

open access: yes, 1994
Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon ...

Visualization of Intracellular Tyrosinase Activity in vitro

open access: yesBio-Protocol, 2016
Melanocytes produce the melanin pigments in melanosomes and these organelles protect the skin against harmful ultraviolet rays. Tyrosinase is the key cuproenzyme which initiates the pigment synthesis using its substrate amino acid tyrosine or L-DOPA (L-3,

Principles of personalized medicine and modern pharmaceutical technologies to optimize levodopa therapy of Parkinson's disease

open access: yesАнналы клинической и экспериментальной неврологии, 2021
Levodopa (3-hydroxy-L-tyrosine, the levorotatory isomerof 3,4-dihydroxyphenylalanine) is a biological precursor of the neurotransmitter dopamine and has been the "gold standard" in the treatment of Parkinsons disease for over 50 years. The widespread use
