In Pseudomonas putida strain G7, a LysR-type positive transcriptional activator protein encoded by nahR is necessary for activation of two operons involved in naphthalene catabolism [Schell, M. A. & Poser, E. F. (1989). J Bacteriol 171, 837-846]. The role of an nahR homologue, NCIB-nahR, in another
Characterization of the anti-inflammatory activity and reduced potential for dermal atrophy of (11 beta, 16 beta)-9-fluoro-1',2',3', 4'-tetrahydro-11,21-dihydroxypregna-1,4-dieno[16,17-b]naph thalene-3, 20-dione hydrate (1 : 1) (SQ 26,490), a topically active corticoid.

Many bacteria that degrade polycyclic aromatic hydrocarbons (PAHs) contain the nahAc gene that encodes a component of multimeric naphthalene dioxygenases. Because the nahAc gene is highly conserved, this gene serves as a potential biomarker for PAH degradation activity. The aim of this research was

In this study, we evaluated whether the abundance of the functional gene nahAc reflects aerobic naphthalene degradation potential in subsurface and surface samples taken from three petroleum hydrocarbon contaminated sites in southern Finland. The type of the contamination at the sites varied from

The preparation and dynamic behavior of two functionally rigid and degenerate [2]rotaxanes (14 PF(6) and 24 PF(6)) in which a pi-electron deficient tetracationic cyclophane, cyclobis(paraquat-p-phenylene) (CBPQT(4+)) ring, shuttles back and forth between two pi-electron-rich naphthalene (NP)
Repeated dose toxicity and relative potency of 1,2,3,4,6,7-hexachloronaphthalene (PCN 66) 1,2,3,5,6,7-hexachloronaphthalene (PCN 67) compared to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) for induction of CYP1A1, CYP1A2 and thymic atrophy in female Harlan Sprague-Dawley rats.

In this study we assessed the relative toxicity and potency of the chlorinated naphthalenes 1,2,3,4,6,7-hexachloronaphthalene (PCN 66) and 1,2,3,5,6,7-hexachloronaphthalene (PCN 67) relative to that of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Chemicals were administered in corn oil:acetone (99:1)

While the role of trefoil factors (TFF) in the maintenance of epithelial integrity in the gastrointestinal tract is well known, their involvement in wound healing in the conducting airway is less well understood. We defined the pattern of expression of TFF1, TFF2, and TFF3 in the airways of mice

Intramolecular and radical-promoted mechanisms for the rearrangement of azulene to naphthalene are assessed with the aid of density functional calculations. All intramolecular mechanisms have very high activation energies (>/=350 kJ mol(-1) from azulene) and so can only be competitive at

Isolation and low-temperature X-ray analyses of intramolecular triarylmethane-triarylmethylium complexes with a naphthalene-1,8-diyl-type skeleton have been achieved. These bridged cations prefer a C--H localized structure both in solution and in the solid state. The bridging hydrogen undergoes a

OBJECTIVE
To examine the retinotoxic effect of naphthalene, a powerful oxidative agent and a well-known cataractogenic agent.
METHODS
A 10% solution of naphthalene dissolved in paraffin oil was given every other day by gavage to 31 pigmented rabbits for 5 weeks, at a dose of 1 g/kg body weight. Four
