BACKGROUND Exposure to certain phenols is ubiquitous because of their use in many consumer and personal care products. However, predictors of exposure have not been well characterized in most populations. OBJECTIVES We sought to identify predictors of exposure and to assess the reproducibility of phenol concentrations across serial spot urine samples among Chinese adults. METHODS We measure...
The oxidation of a number of thioethers, namely methyl phenyl sulphide (1), ethyl phenyl sulphide (2), isopropyl phenyl sulphide (3), n-propyl phenyl sulphide (4), p-chlorophenyl methyl sulphide (5), p-nitrophenyl methyl sulphide (6) and methyl naphthalene sulphide (7), by recombinant pea cytosolic ascorbate peroxidase (rAPX) and a site-directed variant of rAPX in which the distal tryptophan 41...

The asymmetric unit of title compound, [Co(C(3)H(10)NO(7)P(2))(2)(H(2)O)(2)], contains one half-mol-ecule of the complex. The Co(II) atom is located on an inversion centre and displays a distorted octa-hedral coordination geometry defined by four O atoms of two 3-aza-niumyl-1-hy-droxy-propyl-idene-1,1-bis-phospho-nato ligands in the equatorial plane and two water mol-ecules located in axial pos...
THE TITLE COMPOUND [SYSTEMATIC NAME: (2R,3R,4S,5R,6R)-2-(acet-oxy-meth-yl)-6-propoxytetra-hydro-2H-pyran-3,4,5-triyl triacetate], C(17)H(26)O(10), was formed by a Koenigs-Knorr reaction of 2,3,4,6-tetra-O-acetyl-α-d-glucopyranosyl bromide and n-propanol. The central ring adopts a chair conformation. The crystal does not contain any significant inter-actions such as hydrogen bonds.
Green tea catechin and green tea extract are now recognized as non-toxic cancer preventives for humans. We first review our brief historical development of green tea cancer prevention. Based on exciting evidence that green tea catechin, (-)-epigallocatechin gallate (EGCG) in drinking water inhibited lung metastasis of B16 melanoma cells, we and other researchers have studied the inhibitory mech...
Background & Objective: In recent years, mucoadhesive drug delivery systems has shown interested for prolonging the residence time of the dosage form and for providing a controlled rate of drug release. Mucoadhesive buccal films can enhance drug bioavailability by absorption through buccal mucosa and bypassing the first pass metabolism for improved therapeutic effect.. In addition, buccal films...
background: this review was performed to evaluate the trend of alcohol use, characteristics of consumers, alcohol use disorders and toxic alcohol intoxications in bangladesh. in addition, sources and sales figures of alcoholic beverages, and number of legal permits issued for alcohol consumption are reported and analyzed. methods: a narrative search was performed on available medical literature...
The mechanism of propene loss from protonated phenyl n-propyl ether and a series of mono-, di-, and trimethylphenyl n-propyl ethers has been examined by chemical ionization (CI) mass spectrometry in combination with tandem mass spectrometry experiments. The role of initial proton transfer to the oxygen atom and the aromatic ring, respectively, has been probed with the use of deuterated CI reage...
