Treatment of Arsenic Contaminated Groundwater Using Calcium Impregnated Granular Activated Carbon in a Batch Reactor: Optimization of Process Parameters
Authors: Mondal Prasenjit , Mohanty Bikash , Balomajumder Chandrajit 
Published: February 2010

AbstractThis paper is an experimental investigation into the removal of arsenic species from simulated groundwater by adsorption onto Ca2+ impregnated granular activated carbon (GAC‐Ca) in the presence of impurities like Fe and Mn. The effects of adsorbent concentration, pH and temperature on the percentage removal of total arsenic (As(T)), As(III) and As(V) have been discussed. Under the experimental conditions, the optimum adsorbent concentration of GAC‐Ca was found to be 8 g/L with an agitation time of 24 h, which reduced As(T) concentration from 188 to 10 μg/L. Maximum removal of As(V) and As(III) was observed in a pH range of 7–11 and 9–11, respectively. Removal of all the above arsenic species decreased slightly with increasing temperature. The presence of Fe and Mn increased the adsorption of arsenic species. Under the experimental conditions at 30°C, the maximum percentage removals of As(T), As(III), As(V), Fe, and Mn were found to be ca. 94.3, 90.6, 98.0, 100 and 63%, respectively. It was also observed that amongst the various regenerating liquids used, a 5 N H2SO4 solution exhibited maximum regeneration (ca. 91%) of the spent GAC‐Ca.
Epigenetic influence of social experiences across the lifespan
Authors: Champagne Frances A. 
Published: February 2010

AbstractThe critical role of social interactions in driving phenotypic variation has long been inferred from the association between early social deprivation and adverse neurodevelopmental outcomes. Recent evidence has implicated molecular pathways involved in the regulation of gene expression as one possible route through which these long‐term outcomes are achieved. These epigenetic effects, though not exclusive to social experiences, may be a mechanism through which the quality of the social environment becomes embedded at a biological level. Moreover, there is increasing evidence for the transgenerational impact of these early experiences mediated through changes in social and reproductive behavior exhibited in adulthood. In this review, recent studies which highlight the epigenetic effects of parent–offspring, peer and adult social interactions both with and across generations will be discussed and the implications of this research for understanding the developmental origins of individual differences in brain and behavior will be explored. © 2010 Wiley Periodicals, Inc.

Synthesis of Highly Stable CdTe/CdS Quantum Dots with Biocompatibility
Authors: Liu Ying‐Fan , Xie Bing , Yin Zhi‐Gang , Fang Shao‐Ming , Zhao Jian‐Bo 
Published: February 2010

AbstractThioglycolic acid (TGA) is a popular coating material for the preparation of aqueous quantum dots (QDs), yet dihydrolipoic acid (DHLA) has not been studied much. Here we present a detailed study on the aqueous synthesis of CdTe/CdS quantum dots with a DHLA coating. The outer CdS shell and DHLA stabilizer provide efficient confinement of electron and hole wave functions inside the nanocrystal as well as high photochemical stability. At the optimum ratios and reaction conditions, the results indicate that the DHLA‐capped CdTe/CdS QDs exhibit high fluorescence quantum yields (QYs) of about 48 % over a spectral range of 551–571 nm, and the best QY is 87 %. These DHLA‐capped core–shell QDs are highly biocompatible and monodisperse. In particular, they have exhibited excellent colloidal and photostability over one year of study. The synthesis of QDs by using DHLA as stabilizer is simple and environmentally friendly, and it can easily be extended to the large‐scale, aqueous‐phase production of QDs. At a QD dose of 120 μg/mL, TGA‐stabilized CdTe QDs induce 9.5 % hemolysis, whereas DHLA‐stabilized CdTe/CdS QDs induce only 3 % hemolysis. Hemolytic results indicate that DHLA‐stabilized QDs are more biocompatible than TGA‐capped CdTe QDs, which is especially important for QDs as biomarkers in biological detection and diagnosis.
Effect of high‐pressure treatment on microbial activity and lipid oxidation in chilled coho salmon

Published: February 2010

AbstractThis work studies the effect of a previous hydrostatic high‐pressure (HHP) treatment on chilled farmed coho salmon (Oncorhynchus kisutch). Three different HHP conditions were applied (135 MPa‐30 s, 170 MPa‐30 s, and 200 MPa‐30 s for treatments T‐1, T‐2, and T‐3, respectively) and compared to untreated (control) fish throughout a 20‐day chilled storage. Microbial activity and lipid oxidation development were analyzed. Assessment of aerobe, psychrotroph, Shewanella spp. and Pseudomonas spp. counts and trimethylamine formation showed a marked inhibitory effect (p <0.05) of HHP treatment on microbial activity, with this effect increasing with the pressure value employed. Related to lipid oxidation development, higher peroxide mean values (day 10–20 period) were found in control samples and fish treated under T‐1 condition when compared to their counterparts corresponding to T‐2 and T‐3 treatments. On the contrary, quantification of thiobarbituric acid‐reactive substances and fluorescent interaction compounds showed higher levels (p <0.05) in fish samples corresponding to T‐2 and T‐3 treatments. In spite of the lipid oxidation development found, polyene index and tocopherol isomer (α and γ) content did not provide differences (p >0.05) as a result of previous HHP treatment.
A Synthon for the Convenient and Efficient Introduction of Tetrazolylmethyl Groups into Nucleophile‐Bearing Compounds
Authors: Touti Faycal , Avenier Frederic , Lefebvre Quentin , Maurin Philippe , Hasserodt Jens 
Published: February 2010

AbstractAn activated synthon for the efficient introduction of a protected tetrazolylmethyl group into nucleophile‐bearing compounds is presented. The β‐cyanoethyl protecting group allows for very effective deprotection under mild basic conditions. The synthon can be prepared by a two‐step procedure (42 %) starting from cheap starting material and can alkylate piperidine in 91 % yield. Even quadruple alkylation to form a protected version of the hexadentate ligand EDTT gives decent yields. Simultaneous removal of the four protecting groups furnishes the lithium salt of a formally zwitterionic ligand in 75 % yield. Finally, the synthon's performance has been assessed by comparison with its benzyl‐protected counterpart and was found to be equally efficient in the alkylation of simple amines but superior in deprotection. For substrates bearing basic amine sites, the β‐cyanoethyl group is largely preferable.

AbstractMetalloproteases (ADAMs, MMPs) are multidomain proteins that play key roles in extracellular matrix remodelling and degradation, in cell–cell and cell–matrix interactions and in the proteolytic liberation of membrane‐anchored proforms of cytokines and growth factors, the so‐called ectodomainshedding. In this work we describe the development ofphotoactivatable activity‐based probes with which active metalloproteases can be visualised. Our probes are based on the succinyl hydroxamate motif and differ in the positioning of the trifluoromethylphenyldiazirine photoreactive group. We demonstrate that directing the photoactivatable group towards the S1′ pocket yields activity‐based probes more effective than the corresponding probe with the photoactivatable group directed towards the S2′ pocket.
The SNM1/Pso2 family of ICL repair nucleases: From yeast to man
Authors: Cattell Emma , Sengerová Blanka , McHugh Peter J. 
Published: February 2010

AbstractEfficient interstrand crosslink (ICL) repair in yeast depends on the Pso2/Snm1 protein. Pso2 is a member of the highly conserved metallo‐β‐lactamase structural family of nucleases. Mammalian cells possess three SNM1/Pso2 related proteins, SNM1A, SNM1B/Apollo, and SNM1C/Artemis. Evidence that SNM1A and SNM1B contribute to ICL repair is mounting, whereas Artemis appears to primarily contribute to non‐ICL repair pathways, particularly some double‐strand break repair events. Yeast Pso2 and all three mammalian SNM1‐family proteins have been shown to possess nuclease activity. Here, we review the biochemical, genetic, and cellular evidence for the SNM1 family as DNA repair factors, focusing on ICL repair. Environ. Mol. Mutagen. 2010. © 2010 Wiley‐Liss, Inc.
Integrated assessment of oil pollution using biological monitoring and chemical fingerprinting

Published: February 2010

Abstract
A full assessment of the impact of oil and chemical spills at sea requires the identification of both the polluting chemicals and the biological effects they cause. Here, a combination of chemical fingerprinting of surface oils, tissue residue analysis, and biological effects measures was used to explore the relationship between spilled oil and biological impact following the grounding of the MSC Napoli container ship in Lyme Bay, England in January 2007. Initially, oil contamination remained restricted to a surface slick in the vicinity of the wreck, and there was no chemical evidence to link biological impairment of animals (the common limpet, Patella vulgata) on the shore adjacent to the oil spill. Secondary oil contamination associated with salvage activities in July 2007 was also assessed. Chemical analyses of aliphatic hydrocarbons and terpanes in shell swabs taken from limpet shells provided an unequivocal match with the fuel oil carried by the ship. Corresponding chemical analysis of limpet tissues revealed increased concentrations of polycyclic aromatic hydrocarbons (PAHs) dominated by phenanthrene and C1 to C3 phenanthrenes with smaller contributions from heavier molecular weight PAHs. Concurrent ecotoxicological tests indicated impairment of cellular viability (p &lt; 0.001), reduced immune function (p &lt; 0.001), and damage to DNA (Comet assay, p &lt; 0.001) in these animals, whereas antioxidant defenses were elevated relative to un-oiled animals. These results illustrate the value of combining biological monitoring with chemical fingerprinting for the rapid identification of spilled oils and their sublethal impacts on biota in situ. Environ.

Effects of upstaging from PET scan on survival in head and neck squamous cell carcinoma
Authors: Misono Stephanie , Rue Tessa , Rajendran Joseph , Davis Greg E. 
Published: February 2010

AbstractBackground.Stage migration occurs when new diagnostic modalities provide additional information, leading to reclassification of disease stage. Our objective was to examine whether stage migration occurs with inclusion of positron emission tomography (PET) scans in staging head and neck squamous cell carcinoma (HNSCC).Methods.In a retrospective cohort study, subjects were identified through university hospital and Veterans Affairs Medical Center cancer registries with incident HNSCC from 2000 to 2003. American Joint Committee on Cancer (AJCC 6th edition) criteria were used for TNM staging with and without PET scan results. Five‐year survival data were acquired from medical records and the Social Security Death Index.Results.Addition of PET changed TNM classification in 13/65 patients (20%) with stage reclassification in 5/65 patients (8%, p = .03). Apparent stage‐specific 5‐year survival was altered, although these changes were not statistically significant.Conclusions.Although stage migration was documented by inclusion of PET scan information in this series, stage‐specific survival was not significantly changed. Prospective investigation of this phenomenon is necessary. © 2010 Wiley Periodicals, Inc. Head Neck, 2010
Signalling through the RhoGEF Pebble in Drosophila
Authors: Gregory Stephen L. , Lorensuhewa Nirmal , Saint Robert 
Published: February 2010

AbstractSmall GTPase pathways of the Ras superfamily are implicated in a wide range of signalling processes in animal cells. Small GTPases control pathways by acting as molecular switches. They are converted from an inactive GDP‐bound form to an active GTP‐bound form by GTP exchange factors (GEFs). The spatial and temporal regulation of GEFs is a major component of the regulation of small GTPases. Here we review the role of the Drosophila RhoGEF, Pebble (the Drosophila ortholog of mammalian ECT2). We discuss its roles in cytokinesis and cell migration, highlighting the diversity with which Rho family signalling pathways operate in biological systems. © 2010 IUBMB IUBMB Life, 62(4): 290–295, 2010
Manganese exposure alters the expression of N‐methyl‐d‐aspartate receptor subunit mRNAs and proteins in rat striatum
Authors: Xu Bin , Xu Zhao‐Fa , Deng Yu 
Published: February 2010

AbstractManganese is one of the ubiquitous environmental pollutants that can induce an indirect excitotoxicity caused by altered glutamate (Glu) metabolism. The present study has been carried out to investigate the effect of Mn on the expression of N‐methyl‐d‐aspartate receptor (NR) subunit mRNAs and proteins in rat striatum when rats were in manganism. The rats were divided randomly into four groups of six males and six females each: control group (group 1) and 8, 40, and 200 μmol/kg Mn‐treated groups (groups 2–4). The control group rats were subcutaneously (s.c.) injected with normal saline. Manganese‐treated rats were s.c. injected with respectively 8, 40, and 200 μmol/kg of MnCl2 · 6H2O in normal saline. The administration of MnCl2 · 6H2O for 4 weeks significantly increased Mn concentration in the striatum. With the increase in administered MnCl2 dosage, Glu concentration and cell apoptosis rate increased significantly. The relative intensity of NR2A mRNA decreased significantly in 8 μmol/kg Mn‐treated rats. However, relative intensities of NR1 and NR2B mRNAs decreased significantly in 40 μmol/kg Mn‐treated rats. Similarly, the relative intensity of NR2A protein showed a significant decrease in 40 μmol/kg Mn‐treated rats whereas those of NR1 and NR2B decreased significantly in 200 μmol/kg Mn‐treated rats. Therefore, the expression of NR2A mRNA and protein were much more sensitive to Mn than that of NR1 and NR2B. In conclusion, the results suggested that Mn induced nerve cell damage by increasing extracellular Glu level and altered expression of NR subunit mRNAs and proteins in rat striatum. © 2010 Wiley Periodicals, Inc.
