Micrococcu luteus CN1 was found to be able to utilize cyclohexanone well from the strains originally isolated from Pacific Ocean sediment. The optimum conditions for its growth were determined as 25 degrees C -37 degrees C, pH 8, salinity 6%. It could survive in the medium with high concentration of
Cyclohexanone oxime is used primarily as a captive intermediate in the synthesis of caprolactam for the production of polycaprolactam (Nylon-6) fibers and plastics and also in a variety of industrial applications. Cyclohexanone oxime was selected for study because of the potential for human exposure
To clone novel type 1 Baeyer-Villiger monooxygenase (BVMO) genes, we isolated or collected 25 bacterial strains able to grow on alicyclic compounds. Twelve of the bacterial strains yielded polymerase chain reaction (PCR) fragments with highly degenerate primers based on the sequences of known and
Both immunohistochemical and biochemical evidence is presented to show for the first time that carbonic anhydrase II (CA II) activity falls in the brain of mice in cuprizone (bis(cyclohexanone)oxalyldihydrazone) induced demyelination well before demyelination develops. This fall began during the
Studies were conducted of the teratologic effects of ketamine hydrochloride in rats. Ketamine treatment had no significant effect on the number of animals per litter. The histological examination of heart, liver, and kidney showed focal nuclear hypochromatosis and interfibrillary edema; diffuse
OBJECTIVE
Heterogeneity of multiple sclerosis lesions has been recently indicated: In addition to T-cell-mediated or T-cell plus antibody-mediated autoimmune mechanisms (patterns I-II) two other patterns (IIl-IV) were described. Patterns Ill-IV are characterized by primary oligodendrocyte dystrophy,
Exploring and controlling chemical reactions in compartments opens new platforms for designing bioinspired catalysts and energy-autonomous systems. Aqueous polymer networks or hydrogels serve as a perfect model for biological tissues, allowing systematic investigations of chemical transformations in
The size and distribution of mitral cells in the olfactory bulbs of rats were determined using a computer-assisted morphometric technique. Rats were reared from 2 weeks of age for 10 weeks in an animal colony, or in cages through which a stream of deodorized air or cyclohexanone vapor passed.
The objective of this study was to evaluate the potential toxicity of pyrethroids (deltamethrin, permethrin, fenvalerate, λ-cyhalothrin), commercial pyrethroid-based products DECIS EW 50 (deltamethrin mixture), TOP SPOT ON STRONGER (permethrin mixture), as well as related secondary ingredients on
