cresol/dental caries

The authors summarised the literature data of benzylalcohol and amyl-m-cresol. In the clinical practice they used Strepsils in the treatment of 22 patients suffered from oral inflammatic diseases and in the 20 prophylactic cases of oral surgical interventions. The preliminary clinical report shows

Cresol, which is used as a disinfectant and insecticide, has erosive effects on epidermal and epithelial tissues in the body. Oral exposure causes gastrointestinal corrosive injuries as a direct chemical burn. We report herein a case of suicidal poisoning by ingestion of cresol solution. An

The effect of the surface charge density of heptakis-6-bromo-6-deoxy-beta-cyclodextrin (beta-CD-BR) bonded silica gels, which was used as the stationary phase of a packed capillary column for HPLC, was investigated concerning the retention behaviors of neutral cresol isomers. On the whole, the

In this study, the factors in overnight dwell fluid (8 to 10 hr dwell) depressing granulocyte (GC) NAD(P)H-oxidase dependent radical species production are characterized. At present, most studies have essentially focused on fresh, unspent dialysate and on peritoneal macrophages. The response to

The term crude fibre according to the Weend analysis method is insufficient for the nutrition of pigs as it does not comprise pentosanes. During the cooking process they are hydrolysed with diluted acid and do not remain in the crude fibre fraction. As stomach HCl can also hydrolyse pentosane

The type II quinohemoprotein alcohol dehydrogenase of Pseudomonas putida is a periplasmic enzyme that oxidizes substrate alcohols to the aldehyde and transfers electrons first to pyrroloquinoline quinone (PQQ) and then to an internal heme group. The 1.9 A resolution crystal structure reveals that

Recently we reported that the release profile of cinnamaldehyde from a sugar-free chewing gum was correlated to the release of the sugar alcohol phase or was not in agreement with the log P model. The objective of this study was therefore to investigate mechanisms of cinnamaldehyde release from a

The T-shaped host molecule 4,4-bis(4'-hydroxyphenyl)cyclohexanone (1) has an equatorial phenol group and a cyclohexanone group along the arms and an axial phenol ring as the stem. The equatorial phenyl ring adopts a "shut" or "open" conformation, like a windowpane, depending on the size of the guest

The present study utilizes 1H NMR spectroscopy to characterize the binding of substrate to heme active site of three different peroxidases, horseradish peroxidase, lignin peroxidase, and manganese peroxidase. Information has been obtained on the site of p-cresol binding to the active-site cavity of

Considering the importance of the polarizability of the rings of calixarenes in the entropy-driven interaction processes, we examined the effect of entropy compensation on the complex formation of cone and partial cone (paco) conformers of tetranitro-calix [4]arene, possessing O-ethyl substituents

Monte Carlo statistical mechanics simulations have been used to study the complexation of disubstituted benzenes by Diederich's octamethoxy tetraoxaparacyclophane host. Relative free energies of binding were obtained in water at 25 degrees C for benzene, p-xylene, p-cresol, p-dicyanobenzene, and

Using 10 microns thick cryostat-slides of spleen and gut from white rats the following substances (in 2 different concentrations) were tested as substrates for the enzyme phenoloxidase compared with dihydroxyphenylalanine: pyrogallic acid, resorcin, 2.4-dinitrophenol, tyraminhydrochloride, o-cresol,

The catalytic properties of two classes of solid catalysts for the oxidation of hydrocarbons in the liquid phase are discussed: (i) microporous solids, encapsulating transition metal complexes in their cavities and (ii) titanosilicate molecular sieves. Copper acetate dimers encapsulated in molecular

The spectroscopic, conformational, and reactivity characteristics of the T67R variant of sperm whale myoglobin have been studied to assess the effects of introducing an arginine residue into the distal side of this protein, as occurs in the active site of heme peroxidases. The overall circular

Pyrolysis-gas chromatography-mass spectrometry (MS) was used to identify the major organic products produced by pyrolysis of three foundry sand resins: (i) Novolac and (ii) phenolic urethane (PU) (both phenol-formaldehyde based resins) and (iii) furan (furfuryl alcohol based resin). These resins are
