protocatechuic acid/dental caries

Background: In neonatal mice, sevoflurane, inspired through the nasal cavity to act as anesthesia, triggers neuronal apoptosis, inflammation and oxidative injury that can hamper cognitive functions in the growth of the central nervous

The worldwide increase in cancer mortality demands a practical and effective chemopreventive approach to this problem. Using animal bioassay, the authors demonstrated protocatechuic acid (PCA, 3,4-dihydroxybenzoic acid), a simple and antioxidative phenolic acid present in fruits, vegetables, and

Polyphenols, including anthocyanins, from various plant foods are effective in reducing the severity of atherosclerosis in animal and human studies. Due to the poor understanding of the bioavailability of anthocyanins, the potential antiatherogenic mechanisms underlying the action remain largely

Data on the biologic activity of protocatechuic acid are contradictory; some studies have shown that it acts as an antioxidant and suppresses chemical-induced carcinogenesis and others that it induces oxidative stress and promotes tumour formation. The anticarcinogenicity of protocatechuic acid was

We have developed a rapid method that allows us to characterize the binding interaction of sulfobutylether-β-cyclodextrin (SBE-β-CD) with five therapeutically important phenolic acids: ferulic acid, caffeic acid, gallic acid, protocatechuic acid, and vanillic acid. The method utilizes a

The neutral red in vitro cytotoxicity assay was used to evaluate the comparative responses of human cells isolated from tissues of the oral cavity to olive oil phenolics. The cell lines used included normal gingival fibroblasts, immortalized, nontumorigenic gingival epithelial cells, and carcinoma

BACKGROUND Tannases are tannin-degrading enzymes that have been described in fungi and bacteria as an adaptative mechanism to overcome the stress conditions associated with the presence of these phenolic compounds. RESULTS We have identified and expressed in E. coli a tannase from the oral
