Kinetic experiments based on the measurement of nitrogen evolution in the reaction of ethyl diazoacetate (N2CHCO2Et, EDA) and styrene or methanol catalyzed by the [IPrAu](+) core (IPr = 1,3-bis(diisopropylphenyl)imidazole-2-ylidene) have provided evidence that the transfer of the carbene group CHCO2Et to the substrate (styrene or methanol) takes place in the coordination sphere of Au(I) by mean...
This data article contains two figures and one table supporting the research article entitled: "Continuous harvest of stem cells via partial detachment from thermoresponsive nanobrush surface" [1]. The table shows coating conditions of three copolymers, poly(styrene-co-acrylic acid) grafted with oligovitronectin, poly(styrene-co-N-isopropylacrylamide) and poly(styrene-co-polyethylene glycol met...
The metabolism of styrene by prostaglandin hydroperoxidase and horseradish peroxidase was examined. Ram seminal vesicle microsomes in the presence of arachidonic acid or hydrogen peroxide and glutathione converted styrene to glutathione adducts. Neither styrene 7,8-oxide nor styrene glycol was detected as a product in the incubation. Also, the addition of styrene 7,8-oxide and glutathione to ra...
The improvement and modeling of a process for the supply of the volatile aromatic hydrocarbon, styrene, to a fermentor for increased biomass production of the medium chain length polyhydroxyalkanoate (mcl-PHA) accumulating bacterium Pseudomonas putida CA-3 was investigated. Fed-batch experiments were undertaken using different methods to provide the styrene. Initial experiments where styrene wa...
BACKGROUND Within- and between-worker variance components have seldom been reported for both environmental and biological data collected from the same persons. AIMS To estimate these variance components and their ratio for air contaminants and urinary metabolites in two different work environments and to predict the attenuation of exposure-response relationships based on these measures. MET...
OBJECTIVE The aim of this study was to evaluate the expression of a panel of genes involved in toxicology in response to styrene exposure at levels below the occupational standard setting. METHODS Workers in a fiber glass boat industry were evaluated for a panel of stress- and toxicity-related genes and associated with biochemical parameters related to hepatic injury. Urinary styrene metaboli...
A 1.5-kb region immediately downstream of the styABCD operon involved in styrene degradation in Pseudomonas putida CA-3 has been cloned. Sequence analysis revealed a 1,296-bp open reading frame, designated styE, and BLAST P database comparisons of the deduced StyE amino acid sequence revealed 33 to 98% identity with several membrane-associated ATPase-dependent kinase proteins involved in the ac...
