Published: February 2008

AbstractDentin matrix protein1 (DMP1), highly conserved in humans and mice, is highly expressed in teeth, the skeleton, and to a lesser extent in nonskeletal tissues such as brain, kidney, and salivary gland. Pathologically, DMP1 is associated with several forms of cancers and with tumor‐induced osteomalacia. Conventional disruption of the murine Dmp1 gene results in defects in dentin in teeth and in the skeleton, including hypophosphatemic rickets, and abnormalities in phosphate homeostasis. Human DMP1 mutations are responsible for the condition known as autosomal recessive hypophosphatemic rickets. For better understanding of the roles of DMP1 in different tissues at different stages of development and in pathological conditions, we generated Dmp1 floxed mice in which loxP sites flank exon 6 that encodes for over 80% of DMP1 protein. We demonstrate that Cre‐mediated recombination using Sox2‐Cre, a Cre line expressed in epiblast during early embryogenesis, results in early deletion of the gene and protein. These homozygous Cre‐recombined null mice display an identical phenotype to conventional null mice. This animal model will be useful to reveal distinct roles of DMP1 in different tissues at different ages. genesis 46:87–91, 2008. © 2008 Wiley‐Liss, Inc.
Asymmetric Bioreduction of Activated C=C Bonds Using Zymomonas mobilis NCR Enoate Reductase and Old Yellow Enzymes OYE 1–3 from Yeasts

Published: February 2008

AbstractThe asymmetric bioreduction of C=C‐bonds bearing an electron‐withdrawing group, such as an aldehyde, ketone, imide, nitro, carboxylic acid, or ester moiety by a novel enoate reductase from Zymomonas mobilis and Old Yellow Enzymes OYE 1–3 from yeasts furnished the corresponding saturated products in up to >99 % ee. Depending on the substrate type, stereocontrol was achieved by variation of the substrate structure, by switching the (E/Z) geometry of the alkene or by choice of the appropriate enzyme. This substrate‐ orenzyme‐based stereocontrol allowed access to the opposite enantiomeric products.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Design and Validation of a 2 kW‐Fuel Cell Test Bench for Subfreezing Studies
Authors: Bégot S. , Harel F. , Kauffmann J.M. 
Published: January 2008

AbstractThis paper presents the design and validation of a 2 kW fuel cell test bench for subfreezing studies. The test bench is designed to study the influence of different operational parameters on the cold start of fuel cell. Thus, the effects of ambient temperature, gas and coolant flow rates, current density and fuel cell impedance can be investigated. For cold start experiments, the apparatus is designed to reproduce the environment of a fuel cell in a vehicle parked in a subzero environment. Therefore, the test bench is divided into two parts: the fuel cell, its coolant circuit and main sensors are located in a climatic chamber while the main part of the test bench is at room temperature. The different parts of the test bench are described and validation results are presented. The heat exchange between the fuel cell coolant circuit and the environment is computed using parameters estimation techniques. The power requested to heat the coolant circuit to a given temperature is computed.
Membrane Design for Direct Ethanol Fuel Cells: A Hybrid Proton‐Conducting Interpenetrating Polymer Network
Authors: Fu R.‐Q. , Hong L. , Lee J.‐Y. 
Published: January 2008

AbstractA series of hybrid proton‐conducting membranes with an interpenetrating polymer network (IPN) structure was designed with the direct ethanol fuel cell (DEFC) application in mind. In these membranes, glutaraldehyde crosslinked poly(vinyl alcohol) (PVA) were interpenetrated with the copolymer of 2‐acrylamido‐2‐methyl‐propanesulphonic acid (AMPS) and 2‐hydroxyethyl methacrylate (HEMA) crosslinked by poly(ethylene glycol) dimethacrylate (PEGDMA). Silica from the in situ sol–gel hydrolysis of tetraethyl orthosilicate (TEOS) was uniformly dispersed in the polymer matrix. The membranes fabricated as such had ion exchange capacities of 0.84–1.43 meq g–1 and proton conductivities of 0.02–0.11 S cm–1. The membranes exhibited significantly lower fuel permeabilities than that of Nafion. In a manner totally unlike Nafion, fuel permeabilities were lower at higher fuel concentrations, and were lower in ethanol than methanol solutions. These behaviours are all relatable to the unique swelling characteristics of PVA (no swelling in ethanol, partial swelling in methanol and extensive swelling in water) and to the fuel blocking and swelling suppression properties of silica particles. The membranes are promising for DEFC applications since a high concentration of fuel may be used to reduce fuel crossover and to improve the anode kinetics for a resultant increase in both the energy and power densities of the fuel cell.
Evaporation and energy balance of a wet grassland at Tadham Moor on the Somerset Levels
Authors: Harding R. J. , Lloyd C. R. 
Published: January 2008

AbstractWet grasslands are important both for their conservation value and for their important hydrological function. Evaporation is an important component of the water balance of a wetland. Where water is limited rainfall and/or surface (or sub‐surface) inflows are required to balance the summer evaporation and thus become a significant factor in the maintenance and environmental health of a wetland. This study presents an almost complete year of measurements of the water and energy balance of a wet grassland in the Somerset Levels in southwest England. The majority of the radiant energy at this site goes into evaporation. There is a strong seasonality of the controls on evaporation; the roughness length varies by a factor of 10 between winter and summer. The surface resistance to evaporation is low, close to zero, during the winter when the water table is at, or just below the surface. In the summer the water table drops to 80 cm below the surface; there is no sign of soil water stress on the evaporation but a clear effect of the senescence of grass during seed head production and of the subsequent harvest. There is clear evidence that water for evaporation is provided by the drainage ditches through sub‐surface flow. Standard evaporation formulae—such as the Penman‐Monteith equation with constant and standard parameters—provide a reasonable simulation of the total evaporation at this site, although they miss some of the seasonal detail.

Development of a SWAT extension module to simulate riparian wetland hydrologic processes at a watershed scale
Authors: Liu Yongbo , Yang Wanhong , Wang Xixi 
Published: January 2008

AbstractUsing a mass balance algorithm, this study develops an extension module that can be embedded in the commonly used Soil and Water Assessment Tool (SWAT). This module makes it possible to assess effects of riparian wetlands on runoff and sediment yields at a watershed scale, which is very important for aquatic ecosystem management but rarely documented in the literature. In addition to delineating boundaries of a watershed and its subwatersheds, the module groups riparian wetlands within a subwatershed into an equivalent wetland for modelling purposes. Further, the module has functions to compute upland drainage area and other parameters (e.g. maximum volume) for the equivalent wetland based on digital elevation model, stream network, land use, soil and wetland distribution GIS datasets. SWAT is used to estimate and route runoff and sediment generated from upland drainage area. The lateral exchange processes between riparian wetlands and their hydraulically connected streams are simulated by the extension module. The developed module is empirically applied to the 53 km2 Upper Canagagigue Creek watershed located in Southern Ontario of Canada. The simulation results indicate that the module can make SWAT more reasonably predict flow and sediment loads at the outlet of the watershed and better represent the hydrologic processes within it. The simulation is sensitive to errors of wetland parameters and channel geometry. The approach of embedding the module into SWAT enables simulation of hydrologic processes in riparian wetlands, evaluation of wetland effects on regulating stream flow and sediment loading and assessment of various wetland restoration scenarios.

Identifying groundwater pumping source information using simulated annealing
Authors: Lin Yu‐Chung , Yeh Hund‐Der 
Published: January 2008

AbstractThis study develops an approach referred to as SA‐MF using simulated annealing (SA) and a three‐dimensional groundwater flow model (MODFLOW‐2000) to determine the pumping source information, namely the pumping source location, the pumping rate and the pumping period. Eight scenarios, each with various cases for aquifers with homogeneous or heterogeneous conductivities, are used to test the applicability and accuracy of SA‐MF in determining the pumping source information. The results show that at least five measured heads should be used to analyse the pumping source identification problem and at least three observation wells are required to effectively determine the pumping source information. The SA‐MF gives good estimated results in both synthetic and real problems even if the measured heads contain measurement errors. Copyright © 2008 John Wiley & Sons, Ltd.
Children's evaluative categories and inductive inferences within the domain of food
Authors: Nguyen Simone P. 
Published: January 2008

AbstractEvaluative categories include items that share the same value‐laden assessment. Given that these categories have not been examined extensively within the child concepts literature, the present research explored evaluative categorization and induction within the domain of food as a test case. Specifically, two studies examined the categories of healthy and junky foods in children aged 4 and 7 years. Study 1 showed that by aged 4 years, children appropriately apply the evaluative categories of healthy and junky foods to a variety of different foods. Study 2 showed that by age 4 years, children also selectively use the evaluative categories of healthy and junky foods for inductive inferences about the human body, but not for arbitrary or unrelated inferences. Taken together, these results highlight the importance of evaluative processing in young children's categorization and induction. Copyright © 2008 John Wiley & Sons, Ltd.
Antibodies against the cancer‐testis antigen CTSP‐1 are frequently found in prostate cancer patients and are an independent prognostic factor for biochemical‐recurrence

Published: January 2008

AbstractCancer‐testis (CT) antigens are immunogenic proteins expressed in normal gametogenic tissues and in different types of tumors. CTSP‐1 is a CT antigen frequently expressed in prostate tumors, and capable of eliciting humoral response in prostate cancer patients. Here, we analyzed the presence of anti‐CTSP‐1 antibodies in 147 patients with localized prostate cancer and determined its prognostic value for predicting biochemical‐recurrence after radical prostatectomy. Anti‐CTSP‐1 antibodies were detected in 25% of the patients and a significant correlation (p = 0.017) between CTSP‐1 protein expression and the presence of specific humoral response was observed. No association was found between the presence of antibodies and the pathological variables analyzed. On univariate analysis, patients without antibodies against CTSP‐1 had a lower biochemical‐recurrence free survival than did those with anti‐CTSP‐1 antibodies, although the difference between the groups was not statistically significant (57 vs. 75%, p = 0.075). However, the presence of antibodies against CTSP‐1 was significantly associated with a better prognosis in patients with higher Gleason score (36 vs. 80%, p = 0.028). On multivariate analysis, antibodies against CTSP‐1 were associated with a better prognosis (Hazard ratio = 0.41, 95% IC 0.18–0.90 p = 0.039), being the third most powerful prognostic factor among Gleason score and preoperative PSA levels. CTSP‐1 should be considered a promising candidate for prostate cancer immunotherapy, since it is frequently expressed in prostate tumors and capable of eliciting humoral immune response in prostate cancer patients. Our results also suggest that humoral response against CTSP‐1 could be used as a prognostic marker, especially among patients with a high Gleason score. © 2008 Wiley‐Liss, Inc.
Calpain‐mediated pathway dominates cisplatin‐induced apoptosis in human lung adenocarcinoma cells as determined by real‐time single cell analysis
Authors: Liu Lei , Xing Da , Chen Wei R. , Chen Tongsheng , Pei Yihui , Gao Xuejuan 
Published: January 2008

AbstractCisplatin is an efficient anticancer agent. Cisplatin‐based chemotherapy is believed to involve different signal transduction pathways, among which calpain activation has been proposed as an important factor in the induced apoptosis. In our study, based on real‐time single cell analysis, we investigated the molecular involvement of calpain in cisplatin‐induced apoptosis in living human lung adenocarcinoma cells. After cisplatin treatment, calpain was activated, resulting in Bid cleavage at 4–5 hr, followed by Bid translocation and cytochrome c release, leading to cell death. Calpeptin and PD150606, specific inhibitors of calpain, blocked Bid activation completely; however, cytochrome c release was delayed by more than 2 hr, which was associated with the delay of caspase‐3 activation and cell death. Remarkably, calpain‐mediated release of cytochrome c and cell death was significantly compromised in the Bid knockdown cells. Z‐IETD‐fmk and Z‐VDVAD‐fmk were used to block the activation of caspase‐8 and caspase‐2, respectively; however, the progression of apoptosis were not affected, suggesting that caspase‐8 and caspase‐2 were not involved in this experimental model. Taken together, the data demonstrate that calpain mediated cisplatin‐induced apoptosis in human lung adenocarcinoma cells through activating Bid, which then regulated the mitochondrial apoptotic pathway. The delays of cytochrome c release, caspase‐3 activation and subsequent cell death by inactivating calpain or silencing Bid exclude other earlier or parallel pathways, strongly suggesting that the calpain‐mediated pathway is the kinetically earliest one, which dominates the cisplatin‐induced apoptosis. © 2008 Wiley‐Liss, Inc.

AbstractData concerning the fine structure of the 12q13‐15 amplicon which contains MDM2 and CDK4 in well‐differentiated and dedifferentiated liposarcomas (WDLPS/DDLPS) are scarce. We investigated a series of 38 WDLPS/DDLPS using fluorescence in situ hybridization analysis with 17 probes encompassing the 12q13‐15 region. In addition, using quantitative RT‐PCR we studied the expression of MDM2, CDK4, DDIT3 (CHOP/GADD153), DYRK2, HMGA2, TSPAN31 and YEATS4 (GAS41) in 11 cases. We showed that CDK4 (12q14.1) belonged to a distinct amplicon than MDM2 (12q15). There was no continuity in the amplified sequences between MDM2 and CDK4. Moreover, while MDM2 was amplified and overexpressed in all cases, CDK4 was not amplified or overexpressed in 13% of cases. The centromeric border of the CDK4 amplicon was located immediately downstream the 5′ end of DDIT3, a gene known for being involved in myxoid liposarcoma translocations. DDIT3 was amplified in 3 cases and overexpressed in 9 cases. The overexpression of DDIT3 was correlated to the CDK4 amplification and not to its own amplification status. This suggested that the CDK4 amplicon, as well as the overexpression of DDIT3, might be generated by the disruption of a fragile region in 5′ DDIT3. HMGA2 was always amplified and rearranged indicating that it plays a central role in WDLPS/DDLPS. HMGA2 rearrangement frequently resulted in a loss of the 3′ end region that is a binding site for let‐7. We also found a frequent amplification and overexpression of YEATS4, an oncogene that inactivates P53, suggesting that YEATS4 might play an important role together with MDM2 in WDLPS/DDLPS oncogenesis. © 2008 Wiley‐Liss, Inc.
Perceptually inspired HDR images tone mapping with color correction
Authors: Gatta Carlo , Rizzi Alessandro , Marini Daniele 
Published: February 2008

AbstractIn this article we present a novel tone mapping operator (TMO) for high dynamic range (HDR) images. Starting from an algorithm for low dynamic range image enhancement and color correction called ACE (automatic color enhancement), we keep its differential and local behavior, introducing new features to correctly handle the high variation of HDR images. In particular, we add a nonlinear local regulator able to automatically tune the algorithm parameters on image variations. In this way, the algorithm behavior changes according to local variations. Moreover, a key setting feature has been added to control the output appearance; it automatically proposes an appropriate key value for the final spatial invariant display mapping. The proposed method performs the spatial variant filtering using only one parameter, that tunes output detail visibility versus overall contrast. We propose a default setting, that guarantees a good solution in most cases. Test, results, and comparison are presented. © 2008 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 17, 285–294, 2007
