Abstract
We have studied the mutagenic activity and DNA adduct-forming ability of fractionated UPM extractable organic matter (EOM). UPM was collected with a high-volume sampler in June 2004 at two sites, one at street level adjacent to a roadway and the other inside a park within the urban area of the city...

Abstract
Within each condition, similar contributions of fat and carbohydrate were observed despite a wide disparity in speeds. It is hypothesized that fuel selection contributed to preferred walking speeds in the individuals with poststroke hemiparesis and that high rates of carbohydrate oxidation may have...

Abstract
Hepatocellular carcinoma arises from hepatocytes, it is the most common primary malignant tumor of the liver and accounts for the majority of liver cancers. Pirarubicin is a compound analog to the antineoplastic anthracycline antibiotic doxorubicin. Thereby as an intercalator of DNA, pirarubicin has...

Abstract
Over one-third of the world's population has been exposed to Mycobacterium tuberculosis (TB). New drug designs are necessitated by the appearance of multi-drug resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB). This work presents four hydrazide compounds that inhib...

Abstract
Two dinuclear oxovanadium(IV) thiolate complexes, [N(C5H11)4]2[VOL1]2 (1) and [N(C4H9)4][(VOL2)2(mu-OCH3)] (2) (where L1 = [(CH3)SiO(C6H4-2-S)2]3- and L2 = [(C6H5)PO(C6H4-2-S)2]2-), have been synthesized and characterized. The geometry of the anion in 1 can be classified to an edge-sharing bi-square...

Abstract
A pilot-scale subsurface-flow constructed wetland was installed at the Jones County Municipal Landfill, near Anamosa, Iowa, in August 1999 to demonstrate the use of constructed wetlands as a viable low-cost treatment option for leachate generated at small landfills. The system was equipped with a pa...

Effect of hot acid hydrolysis and hot chlorine dioxide stage on bleaching effluent biodegradability.
Abstract
The hot acid hydrolysis followed by chlorine dioxide (A/D*) and hot chlorine dioxide (D*) technologies have proven very useful for bleaching of eucalyptus kraft pulp. Although the characteristics and biodegradability of effluents from conventional chlorine dioxide bleaching are well known, such info...

Abstract
We have investigated the effect of LanL2DZ augmented in the vibrational frequencies. With attention to relative charge and size of the cavity occupied by XO(6) subunit in these anions, we suggest that the general formula [XO(6)(n-)@M(6)O(18)] to describe electronic properties of these anions....

Abstract
[Reaction: see text]. 2-iodobenzenesulfonamide (1a) underwent photostimulated S(RN)1 reactions in liquid NH3 with the potassium enolates derived from acetone, pinacolone, butanone, and 3-methyl-2-butanone to give fair to good yields of 2H-1,2-benzothiazine 1,1-dioxides 2. Reductive dehalogenation of...

Abstract
The ordered perovskite Sr(2)YTaO(6), distrontium yttrium tantalum hexaoxide, has been reported as showing an unusual triclinic structure, at odds with the results from a recent group-theoretical analysis. A new investigation establishes that Sr(2)YTaO(6) and the isostructural Sr(2)YNbO(6), distronti...

Abstract
The ternary oxide MnReO(4), manganese rhenium oxide, has been synthesized under a high pressure of 5.5 GPa at 1473 K and its crystal structure has been determined by single-crystal X-ray diffraction. MnReO(4) crystallizes in a wolframite-type structure with average bond lengths of Re-O = 1.935 and M...

Abstract
The MnNb(2)O(6)-FeNb(2)O(6) solid solution has been investigated by Fe-K- and Mn-K-edge X-ray absorption (XANES and EXAFS), and Mossbauer spectroscopy. The first-shell M-O bond lengths deduced from EXAFS show a fairly small compositional dependence. A degree of static disorder, which increases with...

Cell Transplantation (14)7 2005
Abstract
One impediment for a wider application of islet transplantation is the limited number of donor pancreata for islet isolation. A more efficient utilization of available organs could in part alleviate this problem. Perfluorocarbons (PFCs) have a high oxygen solubility coefficient and maintain high oxy...

Abstract
We review existing definitions, formulas and some other aspects of Delta(17)O reporting. One of the most confusing aspects is a variance of definitions and corresponding formulas. While Delta(17)O is traditionally defined to characterise a data point, i.e. Delta(17)O is considered as a deviation fro...

Abstract
The infrared spectra of polyoxometalates are addressed. The vibration frequencies of some synthesized polyoxometalates in recent years are emphasized. It was found that the infrared spectra of polyoxometalates result from stretch vibration frequency of the metal-oxygen, and 1 100-400 cm(-1) is the r...

Abstract
We analyze this trend and discuss two main lines of thought for the application of polyoxometalates as materials. On the one hand, there is their use as clusters with inherently useful properties on themselves, a line which has produced fundamental studies of their magnetic, electronic or photoelect...

We perform nonlinear sampling in the indirect dimension of MQMAS experiments to substantially reduce the total acquisition time and improve sensitivity and resolution. Nonlinear sampling prevents the use of the discrete Fourier transform; instead, we employ maximum entropy (MaxEnt) reconstruction. N...

Phytochemical Analysis (14)4 2003
Abstract
The compositions of the essential oils isolated from the aerial parts of 11 populations of Thymus caespititius collected during the flowering phase on Pico, Faial and Graciosa (Azores) were studied by GC and GC-MS. The monoterpene fraction was dominant in all the oils analysed (55-90%) and consisted...

Abstract
Investigations of various CeO2 catalysts using XRD, 02-TPD, H2-TPR and catalytic wet air oxidation of phenol showed that CeO2 calcined under higher thermal impact (designated as type A) displayed excellent catalytic ability for the redox reaction of organics. Results of the investigations mentioned...

We recently reported the improved oxygen radical absorbance capacity (ORAC) assay using fluorescein (FL) as the fluorescent probe. The current ORAC(FL) assay is limited in hydrophilic antioxidant due to the aqueous environment of the assay. Lipophilic antioxidants mainly include the vitamin E family...

We report the discovery of unaltered cosmic spherules in a 1.4-Gyr-old sandstone (red bed) from Finland. From this we infer that red beds, a common lithology in the Earth's history, may contain substantial unbiased populations of fossil micrometeorites. The study of such populations would allow syst...

In some areas where oxygenated fuel programs have been implemented, there have been wide-spread complaints of non-specific health effects attributed to the gasoline. There are a number of hypotheses that can account for this apparent association. This paper examines the hypothesis that the use of ox...
