Ascorbic acid in skin health
(MDPI AG, 2019-12)
Ascorbic acid (vitamin C) is a water-soluble vitamin and a recognized antioxidant drug that is used topically in dermatology to treat and prevent the changes associated with photoaging, as well as for the treatment of ...
Allosteric modulation of retinal GABA receptors by ascorbic acid
(Society for Neuroscience, 2011-04)
Ionotropic GABA receptors (GABAA and GABAC) belong to the Cys-loop receptor family of ligand-gated ion channels. GABAC receptors are highly expressed in the retina, mainly localized at the axon terminals of bipolar cells. ...
A comparative study between a brain Na+,K+-ATPase inhibitor (endobain E) and ascorbic acid
(Springer/Plenum Publishers, 2003-06)
In the search of Na+,K+-ATPase modulators, we have reported the isolation by gel filtration and HPLC of a brain fraction, termed endobain E, which highly inhibits Na+,K+-ATPase activity. In the present study we compared ...
Glutathione and ascorbic acid protect Arabidopsis plants against detrimental effects of iron deficiency
(Oxford University Press, 2013-06)
Iron is an essential micronutrient required for a wide variety of cellular functions in plant growth and development. Chlorosis is the first visible symptom in iron-deficient plants. Glutathione (GSH) and ascorbic acid ...
Participation of ascorbic acid in the dormancy establishment of poplar lateral branch buds
(Springer Tokyo, 2014-04-19)
This work studied the participation of ascorbic acid (AA) in the dormancy establishment of apical buds of poplar (Populus deltoides BARTRAM ex MARSHALL cv. Catfish 2) lateral branches. AA content was highest during the ...
Effect of γ-radiation on green onion DNA integrity: Role of ascorbic acid and polyphenols against nucleic acid damage
(Elsevier, 2011-10-27)
The effect of γ-radiation on green onion DNA integrity, phenol content, oxygen radical absorbance capacity, employing pyrogallol red and fluorescein as probes, as well as ascorbic acid content has been evaluated. Measurements ...
Minocycline, but not ascorbic acid, increases motor activity and extends the life span of Drosophila melanogaster.
(Universidad del Zulia, 2013)
Highly selective determination of dopamine in the presence of ascorbic acid and serotonin at glassy carbon electrodes modified with carbon nanotubes dispersed in polyethylenimine
(American Scientific Publishers, 2008-11)
We report the highly selective and sensitive voltammetric dopamine quantification in the presence of ascorbic acid and serotonin by using glassy carbon electrodes modified with a dispersion of multiwall carbon nanotubes ...
Development of HPLC and UV spectrophotometric methods for the determination of ascorbic acid using hydroxypropyl-β-cyclodextrin and triethanolamine as photostabilizing agents
(Elsevier Science, 2010-02)
In this study, the effect of complex formation with triethanolamine (TEA) alone and in combination with hydroxypropyl-b-cyclodextrin (HP-b-CD) on the photostability of ascorbic acid was evaluated for exposure to artificial ...
Flow-injection spectrophotometric method with on-line photodegradation for determination of ascorbic acid and total sugars in fruit juices
(Academic Press Inc Elsevier Science, 2011-02)
This article reports a flow-injection spectrophotometric determination (FIA) with a photodegradation step to determine ascorbic acid and total sugars. The flow-injection system includes a simple ultraviolet photoreactor ...
