Sedimentary Enzyme Kinetics of Land/Water Ecotones with Reed Domination
Authors: Wang Liang , Yin Chengqing , Wang Weidong 
Published: February 2010

AbstractLand/water ecotones, the transitional boundary zone between terrestrial and aquatic ecosystems, can effectively trap and assimilate nutrients from external sources. The changes of nutrient cycling will cause a response in enzyme activity. In this paper, the enzyme kinetics of land/water ecotones in a shallow eutrophic wetland in China, dominated by a reed (Phragmites australis) community, are studied. The results indicate that land/water ecotones exhibit a strong filtration function and nutrient factor is an important feature affecting the distribution of enzymes in the transect of the littoral zone. The obvious spatial differences of enzyme activities and nutrients are present in the transect of the reed beds. The land area is the hot zone, where significant changes in enzyme activity occur. T‐test results show that the landward spot, 1 m away from the water‐land interface, is quite different from other spots, and the 1 m spot is the hot spot where great biochemical change happens. The principal component analysis of the environmental variables shows that nutrient factors have an important affect on enzyme distribution in the transect of the littoral zone. The nutrient factor explains about 54% of the observed variance. In particular, TOC (total organic carbon) correlates with the other five factors (TN; total nitrogen, TP; total phosphorus, phosphatase, β‐glucosidase, and urease) with correlative coefficients of 0.932, 0.595, 0.488, 0.433, and –0.468, respectively. The results indicate that TOC is a very important factor in Baiyangdian wetlands.
Electrokinetic Removal of Petroleum Hydrocarbon from Residual Clayey Soil Following a Washing Process
Authors: Jeon Chil‐Sung , Yang Jung‐Seok , Kim Kyung‐Jo , Baek Kitae 
Published: February 2010

AbstractThis study investigates total petroleum hydrocarbon (TPH) removal from residual clayey soil, after a washing procedure, using an electrokinetic process. Eight electrokinetic experiments were carried out to investigate the characteristics of TPH removal. When 0.1 M MgSO4 or 0.1 M NaOH was used as an electrolyte, the electric current rapidly increased within the first 100 or 200 h, respectively. A negatively charged soil surface resulted in a more negative zeta potential and greater electroosmotic flow toward the cathode. Therefore, the accumulated electroosmotic flow (EOF) when using 0.1 M NaOH as the anolyte‐purging solution was higher than when using 0.1 M MgSO4. Although the energy consumption for the two purging solutions was similar, the efficiencies of TPH removal when 0.1 M MgSO4 and 0.1 M NaOH with surfactant were used were 0 and 39%, respectively, because the electroosmotic flow rate increased with TPH removal efficiency. When 5% isopropyl alcohol (IPA) was used as a circulation solution, the electric current increased but the TPH removal was similar to that using water. In terms of energy consumption, the use of a surfactant‐enhanced electrokinetic process with NaOH as electrolyte was effective in removing TPHs from low‐permeability soil.

Synthesis, Structure, and Spectroscopic Properties of the New Lanthanum(III) Fluoride Oxomolybdate(VI) La3FMo4O16
Authors: Hartenbach Ingo , Strobel Sabine , Schleid Thomas , Sarkar Biprajit , Kaim Wolfgang , Nockemann Peter , Binnemans Koen , Dorhout Peter K. 
Published: February 2010

AbstractLa3FMo4O16 crystallizes in the triclinic crystal system with space group P$\bar {1}$ [a = 724.86(2) pm, b = 742.26(2) pm, c = 1469.59(3) pm, α = 101.683(2)°, β = 102.118(2)°, γ = 100.279(2)°] with two formula units per unit cell. The three crystallographically independent La3+ cations show a coordination number of nine each, with one F– and eight O2– anions forming distorted monocapped square antiprisms. The fluoride anion is coordinated by all three lanthanum cations to form a nearly planar triangle. Besides three crystallographically independent tetrahedral [MoO4]2– units, a fourth one with a higher coordination number (CN = 4 +1) can be found in the crystal structure, forming a dimeric entity with a formula of [Mo2O8]4– consisting of two edge‐connected square pyramids. Several spectroscopic measurements were performed on the title compound, such as infrared, Raman, and diffuse reflectance spectroscopy. Furthermore, La3FMo4O16 was investigated for its capacity to work as host material for doping with luminescent active cations, such as Ce3+ or Pr3+. Therefore, luminescence spectroscopic as well as EPR measurements were performed with doped samples of the title compound. Both the pure and the doped compounds can be synthesized by fusing La2O3, LaF3 and MoO3 (ratio 4:1:12; ca. 1 % CeF3 and PrF3 as dopant, respectively) in evacuated silica ampoules at 850 °C for 7 d.
Protonation of Cp*M(dppe)H Hydrides: Peculiarities of the Osmium Congener

Published: February 2010

AbstractThe interaction between Cp*OsH(dppe) (1) and a series of proton donors (HA) of increasing strength [indole, CFH2CH2OH (MFE), CF3CH2OH (TFE), (CF3)2CHOH (HFIP), p‐nitrophenol, and HBF4·Et2O] has been investigated experimentally by variable temperature IR and NMR spectroscopy in solvents with different coordinating abilities (alkanes, dichloromethane and their mixtures) and computationally at the DFT/B3PW91 level using different models. Both the IR and NMR spectroscopic data for the interaction with weak proton donors conform to the criteria of M–H···H‐A bond formation. Theoretical calculations, however, indicate an asymmetric bifurcated interaction with a significant contribution from the metal atom, which is greater than that previously found for the corresponding Fe system. The basicity factor of 1 (Ej = 1.47) is greater than those of the Ru (1.39) and Fe (1.35) congeners, in agreement with previous studies on other compound families. The kinetic product of proton transfer, cis‐[Cp*Os(H)2(dppe)]+X–, which is selectively obtained at low temperatures, irreversibly rearranges to trans‐[Cp*Os(H)2(dppe)]+X– upon warming to >230 K. The latter compound with X = BF4 has been crystallographically characterized. The activation enthalpy of the isomerization process (ΔH≠ = 21.5 ± 1.0 kcal mol–1), obtained from kinetics investigation by 1H NMR in the 240–260 K range, is identical within experimental error to those previously reported for the M(η2‐H2)+BF4– → trans‐M(H)2+BF4– isomerization process of the iron and ruthenium analogues. The activation entropy (ΔS≠ = 12 ± 4 e.u.), on the other hand, is greater than for the lighter metals, following the order Fe < Ru < Os. The mechanism of proton transfer and trends in the energetics of the various steps upon changing the nature of the metal atom are discussed.
Betaine supplementation affects the cholesterol but not the lipid profile of pigs
Authors: Martins José M. , Neves José A. , Freitas Amadeu , Tirapicos José L. 
Published: February 2010

AbstractThis study was undertaken to investigate the effects of long term betaine intake on the cholesterol and lipid profile of Alentejano (AL) pigs. At ˜36 kg body weight (BW), castrated male and female pigs fed a commercial (C) diet, were divided into two groups: i) Group C, consuming the C diet; and ii) Group CB, consuming the C diet supplemented with 1 g/kg betaine. Pigs were slaughtered at ˜100 kg BW. Fasting plasma concentrations of protein, urea, glucose, TAG, phospholipids, homocysteine, total and LDL‐ and HDL‐cholesterol were determined. Liver TAG, phospholipids, and total and free cholesterol were analyzed, as well as total lipids, cholesterol contents, and fatty acid (FA) composition of M. semimembranosus and dorsal subcutaneous fat. Betaine supplemented pigs presented significantly higher plasma concentrations of TAG, phospholipids, cholesterol, and lipoprotein cholesterol. Dorsal subcutaneous fat cholesterol concentration was also significantly higher in CB than in C pigs. No differences were detected in the most abundant FA profile (including the unsaturated to saturated FA ratio) of muscle and subcutaneous fat tissues among treatments. These data suggest that betaine induces dyslipidemia, and increases cholesterol concentration in dorsal subcutaneous fat, without affecting the FA profile of M. semimembranosus and dorsal subcutaneous fat.
Loss of expression of ZAC/PLAGL1 in diffuse large B‐cell lymphoma is independent of promoter hypermethylation
Authors: Valleley Elizabeth M. A. , Cordery Sarah F. , Carr Ian M. , MacLennan Kenneth A. , Bonthron David T. 
Published: February 2010

AbstractZAC/PLAGL1 is a ubiquitously expressed, imprinted tumor suppressor gene located on 6q24, a chromosomal region that is frequently deleted in diffuse large B‐cell lymphoma (DLBCL). Like p53, ZAC regulates cell cycle arrest and apoptosis concomitantly, and loss of expression is implicated in tumorigenesis in a variety of different cancers. In most tissues, ZAC transcription is monoallelic and driven by the paternal allele of promoter P1, which lies within a differentially methylated CpG island (DMR). In human blood cells, ZAC transcription is driven by promoter P2, which lies within an unmethylated CpG island and produces biallelic transcripts. Previous reports of epigenetic changes of ZAC in tumors have focused on P1, showing frequent loss of expression caused by paternal allele hypermethylation or loss of heterozygosity (LOH). As ZAC expression in normal B lymphocytes is derived from P2, in DLBCL we analyzed both promoters for gene expression, LOH and abnormal methylation. Loss of P2 transcription was observed in 8 of 11 lymphomas (73%), even though the P2 CpG island remained unmethylated. Three lymphomas showed evidence of LOH (23%), and abnormal methylation of the P1 DMR was observed in an additional four (31%), despite minimal P1 activity in normal B lymphocytes. These data indicate that downregulation of ZAC occurs in DLBCL, as in other cancers. However, unlike P1, transcriptional repression of P2 is not caused by hypermethylation of its associated CpG island in tumors. The mechanistic relationship between altered ZAC expression and epigenetic changes at its promoters thus appears more complex than previously supposed. © 2010 Wiley‐Liss, Inc.
Arterial spin labeling at ultra‐high field: All that glitters is not gold
Authors: Teeuwisse Wouter M. , Webb Andrew G. , van Osch Matthias J. P. 
Published: February 2010

AbstractIn the past decade, MRI perfusion imaging has become increasingly important in the radiological clinic. Herein, arterial spin labeling (ASL) represents a truly noninvasive method for assessment of hemodynamic changes. Recently, whole body scanners that operate at a field strength of 7 Tesla or above have become available, carrying the promise of higher signal to noise ratio. In this article, we discuss the basic ASL methods that are available today and the problems that may be encountered when implementing ASL on a high field scanner. Particularly, B0 and B1 field inhomogeneities and fluctuations in precession frequency due to respiration were measured at the level of the brain feeding arteries. The effect of these disturbances on ASL is being discussed as are other issues such as specific absorption rate and relaxation rates. It can be concluded that implementation of ASL on MRI systems with high field strength is not trivial, although the feasibility of ASL measurements has been demonstrated at 7 Tesla. Further improvements can be expected, for example by the use of local labeling coils and improved shimming and preparation methods. © 2010 Wiley Periodicals, Inc.

Challenges for molecular neuroimaging with MRI
Authors: Lelyveld Victor S. , Atanasijevic Tatjana , Jasanoff Alan 
Published: February 2010

AbstractMagnetic resonance (MRI)‐based molecular imaging methods are beginning to have impact in neuroscience. A growing number of molecular imaging agents have been synthesized and tested in vitro, but so far relatively few have been validated in the brains of live animals. Here, we discuss key challenges associated with expanding the repertoire of successful molecular neuroimaging approaches. The difficulty of delivering agents past the blood‐brain barrier (BBB) is a particular obstacle to molecular imaging in the central nervous system. We review established and emerging techniques for trans‐BBB delivery, including intracranial infusion, BBB disruption, and transporter‐related methods. Improving the sensitivity with which MRI‐based molecular agents can be detected is a second major challenge. Better sensitivity would in turn reduce the requirements for delivery and alleviate potential side effects. We discuss recent efforts to enhance relaxivity of conventional longitudinal relaxation time (T1) and transverse relaxation time (T2) MRI contrast agents, as well as strategies that involve amplifying molecular signals or reducing endogenous background influences. With ongoing refinement of imaging approaches and brain delivery methods, MRI‐based techniques for molecular‐level neuroscientific investigation will fall increasingly within reach. © 2010 Wiley Periodicals, Inc.

Abstract“Diffusion Tensor Imaging” (DTI) has the unique capability to represent the macroscopic white matter architecture. Based on DTI, tractography is able to render 3D trajectories of tracts. There are no other technique that can produce equivalent anatomical information, and, thus, tractography is a powerful method to investigate human brain anatomy. Here, we present an overview of the principles, advantages, shortcomings and possibilities of these methods. © 2010 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 20, 51–56, 2010
Cytotoxicity and genotoxicity induced by aflatoxin B1, ochratoxin A, and their combination in cultured Vero cells

Published: February 2010

AbstractAflatoxin B1 (AFB1) and ochratoxin A (OTA) are important food‐borne mycotoxins that have been implicated in human health. In this study, independent and combinative toxicities of AFB1 and OTA were tested in cultured monkey kidney Vero cells. The experiments reported here were conducted to evaluate the effect of these toxins on cell viability followed by the determination of cell death pathways, using the quantification of DNA fragmentation and the expression of p53 and bcl‐2 protein levels. Our results showed that AFB1 and OTA caused a marked decrease of cell viability in a dose‐dependent manner. Under the same conditions, these mycotoxins increased fragmented DNA levels. In addition, p53 was activated in response to DNA damage and the expression of the antiapoptotic factor bcl‐2 decreased significantly. According to these data, AFB1 and OTA seemed to be involved in an apoptotic process. Moreover, combined AFB1 and OTA induced all the toxicities observed with the mycotoxins separately. Therefore, this combination was classified as an additive response of the two mycotoxins. © 2010 Wiley Periodicals, Inc.
