Pseudomonas veronii MEK700 was isolated from a biotrickling filter cleaning 2-butanone-loaded waste air. The strain is able to grow on 2-butanone and 2-hexanol. The genes for degradation of short chain alkyl methyl ketones were identified by transposon mutagenesis using a

An electrophysiological study of the neurotoxicity of 2-octanone (an analogue of methyl n-butyl ketone) and 2-hexanol (a metabolite of n-hexane) was conducted on rats as a part of the study to determine the specific molecular arrangement required for the development

Archives of toxicology, 71(4), 238-242 (1997-01-01)
In order to study the mechanisms of acute n-hexane intoxication, the effects of n-hexane and its metabolites 2-hexanol, methyl-n-butyl ketone, 2,5-hexanediol and 2,5-hexanedione on the cloned voltage-operated potassium channels Kv1.1, Kv1.4, Kv2.1 and Kv3.4 were investigated with electrophysiological techniques in

1. The role of skeletal muscle microsomes as a site of extrahepatic xenobiotic metabolism using n-hexane as a model substrate was investigated. The observed cytochrome P450-dependent metabolism was compared with that found with liver, and brain microsomal fractions. 2. Rat

The capability of the cockroach Periplaneta americana to discriminate odors of structurally similar aliphatic alcohols was studied by using an operant conditioning paradigm. Cockroaches were trained to discriminate three odors: one odor associated with sucrose solution (reward) and two odors

It is well known that n-hexane produces peripheral neuropathy, and 2,5-hexanedione, one of the metabolites of n-hexane, is thought to be the main causative agent. Recently, the metabolites of n-hexane in urine have been measured by gas chromatography, and 2,5-hexanedione
P Manini et al.
Toxicology letters, 108(2-3), 225-231 (1999-10-08)
Since n-hexane metabolites are excreted as glucuronide conjugates, most conventional analytical procedures require preliminary hydrolysis, yielding to the 'total' 2,5-hexanedione (2,5-HD), but also giving rise to a number of artifacts. The whole pattern of n-hexane metabolites, both conjugated and unconjugated

In this study, the combination of two chiral components in a microemulsion formulation for the separation of enantiomers via microemulsion EKC (MEEKC) was successfully accomplished. Previous publications of chiral microemulsions have utilized only one chiral entity; the surfactant, cosurfactant, or

An expression profile of genes induced by non-pathogenic Alternaria alternata on rough lemon leaves was obtained by sequencing 500 subtractive PCR clones generated from mRNA of leaves inoculated with the fungus after subtraction with that of non-inoculated leaves. About 6%

This paper reports a QSAR study for predicting the complexation of a large and heterogeneous variety of substances (233 organic compounds) with beta-cyclodextrins (beta-CDs). Several different theoretical molecular descriptors, calculated solely from the molecular structure of the compounds under investigation

1. The in vitro metabolism of n-hexane was studied in rat liver, lung, brain and skeletal muscle microsomes and in microsomes prepared from cell lines expressing human cytochrome P-450 2E1 or 2B6. The hydroxylated metabolites of n-hexane were quantified by
Zhi-Xia Zheng et al.
Electrophoresis, 25(18-19), 3263-3269 (2004-10-09)
A novel chiral microemulsion, which involved the use of chiral alcohols as cosurfactants, was demonstrated for the enantiomeric separation of a number of pharmaceutical drugs in microemulsion electrokinetic chromatography (MEEKC). The chiral alcohols investigated were optically active 2-alkanols, with the

The chemical composition of Porella arboris-vitae extracts was determined by solid phase microextraction, gas chromatography-mass spectrometry (SPME GC-MS), and 66 constituents were identified. The dominant compounds in methanol extract of P. arboris-vitae were β-caryophyllene (14.7%), α-gurjunene (10.9%), α-selinene (10.8%), β-elemene

The metabolic fate of methyl n-butyl ketone (MnBK) and its isomer methyl isobutyl ketone (MiBK) was studied in mice. The concentrations of both ketones and their metabolites in blood and brain were measured at different time intervals after their administration.

The "across-neuron pattern" theory of olfactory information coding states that odorants are represented by spatial patterns of activity produced across-neurons in the olfactory bulbs. The present study analyzes the different response patterns encoding olfactory information in both the inspiratory and

The primary olfactory neuropil, the antennal lobe (AL) in insects, is organized in glomeruli. Glomerular activity patterns are believed to represent the across-fibre pattern of the olfactory code. These patterns depend on an organized innervation from the afferent receptor cells

In vitro systems of high biological organization, e.g. containing intact hepatocytes, have been considered as more reliable for metabolic studies and in vivo predictions of toxicokinetics than subcellular systems. For this reason, the kinetics and metabolism of low-molecular-weight volatile chemicals

The Meyer-Overton rule has been interpreted to mean that general anesthetics act at a nonpolar site, either in a lipid bilayer or a protein. Optical isomers, also called enantiomers, are pairs of compounds with the same molecular formula and functional
