pyruvic acid/dental caries

Etching of enamel surfaces produces a marked increase in the bond strength of dental materials to tooth structure. The results of recent studies have indicated that pyruvic acid may be used in preference to phosphoric acid, because of its milder etching effect on enamel surfaces, without adversely

The behaviour of caries has been studied in rats kept on a cariogenic diet enriched with zinc and vit. B6. A reduction of 16.7% in caries was observed compared to control animals fed with the cariogenic diet alone. Compared to the controls, the animals treated with Ershoff diet and zinc presented a

The dynamics of overtone-excited pyruvic acid (PA) is studied using a combination of experimental and theoretical methods. It is experimentally observed that high overtone excitation of the OH-stretching mode of PA in the gas phase leads to a unimolecular decarboxylation reaction. An RRKM analysis

Intermolecular interactions between pyruvic acid, the simplest α-keto acid, and water are important in bio- and atmospheric chemistry. In this context, the pure rotational spectrum of the pyruvic acid-water complex was measured from 7 to 15 GHz using a cavity-based Fourier-transform microwave

BACKGROUND According to Warburg's effect, the rate of glycolysis increases in cancerous cells. This will increase overall levels of pyruvic acid. The present on-going study was conducted to estimate the levels of pyruvic acid in saliva and serum in normal, oral PMD subjects. METHODS A total of 50

OBJECTIVE To investigate the mechanism of lemon peel essential oil (LPE) on the cariogenicity of Streptococcus sobrinus (Ss). METHODS LPE was extracted by the authors, and the minimum inhibition concentration (MIC) was measured by disc diffusion method. The LPE was used as the experimental group

In rare instances, chronic alcoholism leads to the congestive heart failure which is characteristic of alcoholic beriberi with edema. The affected patients is usually a young man with longstanding alcoholic intoxication and often with neurologic features. Onset is often sudden, with dyspnea on

We describe the design and initial performance results of a multi-sample dissolution dynamic-nuclear-polarization (DNP) polarizer based on a Helium-temperature NMR cryostat for use in a wide-bore NMR magnet with a room-temperature bore. The system is designed to accommodate up to six samples in a

In addition to lowered pH values, the molecular profile and concentrations of microbial-derived organic acids in carious dentin are important demineralization parameters involved in the induction, development and progression of dental caries. High-resolution proton ((1)H) NMR spectroscopy was

OBJECTIVE Recent studies have suggested that β-asarone have neuroprotective and cardiovascular protective effects in animal model. However, the influence of β-asarone on cerebrovascular system has not been explored so far. Therefore, present study was designed to determine whether repeated exposures
