Influence of Phenolic Acids on Ion Uptake: IV. Depolarization of Membrane Potentials.
The membrane potentials of aged, excised barley (Hordeum vulgare L.) root cells were rapidly depolarized by the addition of salicylic acid (o-hydroxybenzoic acid) to the buffered medium bathing root segments. Initial values for membrane potentials were restored very slowly (within 100 minutes) by replacing the phenolic solution by phenolic-free buffer. Several other naturally occurring benzoic ...

بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Influence of phenolic acids on growth and inactivation of Oenococcus oeni and Lactobacillus hilgardii.
AIMS To determine the effect of several wine-associated, phenolic acids on the growth and viability of strains of Oenococcus oeni and Lactobacillus hilgardii. METHODS AND RESULTS Growth was monitored in ethanol-containing medium supplemented with varying concentrations of hydroxybenzoic acids (p-hydroxybenzoic, protocatechuic, gallic, vanillic and syringic acids) and hydroxycinnamic acids (p-...
متن کاملAntimutagenic effect of phenolic acids.
In the present study, the Salmonella typhimurium tester strain TA 100 was used in the plate-incorporation test to examine the antimutagenic potential of caffeic, ferulic and cichoric acids extracted from plant species of genera Echinacea (L) Moench, as well as of another phenolic acids, on 3-(5-nitro-2-furyl)acrylic acid (5NFAA) and sodium azide mutagenicity. All tested compounds possess antimu...
متن کاملEffects of organic acids on ion uptake and retention in barley roots.
Effects of several organic acids on ion uptake and retention and on respiration in barley roots having low and high KCl contents were assayed by measurements of K(+), Na(+), Ca(2+), Cl(-), and oxygen uptake. Organic acids with high pK(a) values increase the permeability of roots to ions and decrease respiration when present in sufficient concentrations at pH 5 but have no inhibitory effects at ...
