butyric acid/dental caries

The composition of pooled resting plaque fluid from 10 population samples, grouped according to age (8-11, 14-17, 18-25 years) and caries status (caries-free, CF, DMFS = 0; caries-susceptible, CS, DMFS greater than 10), was determined by means of ion chromatography. Subjects received a dental

The oral microbiome is composed of detrimental and beneficial microbial communities producing several microbial factors that could contribute to the development of the oral microbiome and, likewise, may lead to the development of host diseases. Metabolites, like short-chain fatty acids, are commonly

A novel and general method for the synthesis of H-aggregates is presented. H-aggregates can be precipitated from solutions of cyanine dyes in nanostructured [6,6]-phenyl C(61)-butyric acid methyl ester (PCBM) template films. H-aggregates synthesized that way have a narrow line shape width comparable

The crystal structures of the complexes of heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin with indole-3-butyric acid and with 2,4-dichlorophenoxyacetic acid were studied by X-ray diffraction. The complexes crystallize in the monoclinic P2(1) space group. The host molecules are elliptically puckered

Seven hydrophobic residues ranging in size from glycine to phenylalanine have been substituted for the wild-type methionine residue at position 13 in a 15-residue truncated version (S15) of S-peptide, the small component of ribonuclease S. Complexes of both S-15 and the seven variants with S-protein

The causes of periodontal disease are complex. Butyric acid, a metabolite of periodontopathic bacteria such as Porphyromonas gingivalis, acts as a histone deacetylase inhibitor that has a direct effect on mRNA expression. Butyric acid produced by Clostridium butyricum in the intestinal tract induces

Periodontopathic bacteria such as Porphyromonas gingivalis produce a large amount of butyric acid as a metabolite. Though butyric acid has been reported to have an anti-inflammatory effect on inflammatory diseases in the gastrointestinal tract, it has been

Latently infected cells harbor human immunodeficiency virus type 1 (HIV-1) proviral DNA copies integrated in heterochromatin, allowing persistence of transcriptionally silent proviruses. It is widely accepted that hypoacetylation of histone proteins by histone deacetylases (HDACs) is involved in

Auxin is a crucial phytohormone for precise control of growth and development of plants. Due to its low concentration in plant tissues which are rich in interfering substances, the accurate determination of auxins remains a challenge. In this paper, a new strategy for isolation and enrichment of

The metabolism of the tobacco-specific carcinogen, 4-(N-methyl-N-nitrosamino)-1-(3-pyridyl)-1-butanone (NNK), was studied in the F344 rat, in which it induces tumors of the nasal cavity, liver, and lung. When NNK was incubated with rat liver microsomes and a reduced nicotinamide adenine dinucleotide

UNASSIGNED The aim of this study was to investigate the microhardness and microstructural features of newer tricalcium silicate materials: TheraCal LC, mineral trioxide aggregate (MTA), biodentine (BD), and Endosequence Root Repair Material (ERRM) putty, after exposure to acidic environments in

Present work reports the photophysical insights on supramolecular interaction of a C₇₀ derivative, namely, [6,6]-phenyl C₇₁ butyric acid methyl ester (PC₇₀BM), with two designed diporphyrin molecules having dithiophene (1) and carbazole (2) spacer in toluene and benzonitrile. Both absorption

The distribution and metabolism of [5-3H]N'-nitrosonornicotine ([5-3H]NNN) was studied in three 18-day-old miniature pigs. [5-3H]NNN was administered by intracardiac administration into the right ventricle of the heart to mimic uptake by the lung. Whole body autoradiograms taken 15-220 min after

OBJECTIVE Periodontitis is a destructive disease which is likely to be the result of the activities of different microbial complexes. Recently, sulphate-reducing bacteria (SRB) have been detected in the oral cavity, and they have been found to be common inhabitants of sites showing periodontal

Interfacial layers are frequently used in organic solar cells performing various functions, including blocking surface recombination, improving selectivity of charge carrier extraction, modification of the work function of the contact materials, and enhancing light absorption within the photoactive
