AbstractBackgroundRecent advances in stem cell therapy to restore cardiac function have great promise for patients with congestive heart failure after myocardial infarction in an adult population.ObjectiveWe examined the benefits of bone marrow‐derived progenitor cells treatment modality for the pediatric patient.Methods and ResultsWe present our first case of transcoronary autologous stem cell transplantation in a 9‐year‐old girl with refractory congestive heart failure secondary to myocardial infarction 1 year after transcatheter revascularization. The child received daily injections of granulocyte colony‐stimulating factor for 3 days prior to the bone marrow aspiration. The bone marrow cells were isolated to constitute CD133 + /CD34 + more than 90% of the total number. Subsequently, the progenitor cell suspension was injected via a transcoronary catheter without any complication. Three months after stem cell therapy, her cardiac function, assessed by both cardiac magnetic resonance and echocardiogram, has been improved with the left ventricular ejection fraction at 47% compared to the baseline of 30%.ConclusionThis is the first reported pediatric case of successful transcoronary injection of bone marrow‐derived progenitor cells for end‐stage heart disease. The procedure is considered safe and feasible for the pediatric population. Copyright © 2010 Wiley Periodicals, Inc.
A two‐tier framework for transmission‐cost minimization of high‐performance communication applications
Authors: Hu Chia‐Cheng , Lai Chin‐Feng , Huang Yueh‐Min , Chao Han‐Chieh 
Published: June 2010

SUMMARYIn two‐tier high‐performance networks (HPNs), some facilities are constructed to form a powerful supercomputing environment, and to alleviate server load. Then, the applications are provided by them in co‐operated, parallel and distributed manners. A proper way to select facilities is crucial to the performance of two‐tier HPNs The problem of selecting facilities can be regarded as a kind of the facility location problem, which is to determine an optimal subset of facilities that will be open to serve users. The traditional facility location problem aims to minimize the incurred costs between the users/servers and their assigned facilities. In two‐tier HPNs, the incurred costs can be regarded as the transmission costs, e.g. transmission latency, bandwidth overhead. We observe that most of the packets are transmitted among the facilities for application servicing and framework maintaining. In this paper, we address the problem of selecting facilities in two‐tier HPNs by minimizing the transmission costs from servers to users by passing through the selected facilities. Our problem is different from the traditional facility location problem, which only considers the transmission costs between the users/servers and their assigned facilities. In our problem, the transmission costs between the selected facilities are further considered. The problem is formulated as a 0/1 integer non‐linear programming (0/1 INLP) and 0/1 integer linear programming (0/1 ILP). Further, a simple heuristic algorithm is proposed for obtaining a feasible solution when the network sizes increase, since solving INLPs and ILPs for large‐scale problems takes long time.

Communicating subcellular distributions
Authors: Murphy Robert F. 
Published: June 2010

AbstractTo build more accurate models of cells and tissues, the ability to incorporate information on the distributions of proteins (and other macromolecules) will become increasingly important. This review describes current progress towards determining and representing protein subcellular patterns so that the information can be used as part of systems biology efforts. Approaches to decomposing an image of the subcellular pattern of a protein give critical information about the fraction of that protein in each of a number of fundamental patterns (e.g., organelles). Methods for learning generative models from images provide a means of capturing the essential properties and variation in those properties of cell shape and organelle patterns. The combination of models of fundamental patterns and vectors specifying the fraction of a protein in each of them provide a much better means of communicating subcellular patterns than the descriptive terms that are currently used. Communicating information about subcellular patterns is important not only for systems biology simulations but also for representing results from microscopy experiments, including high content screening and imaging flow cytometry, in a transportable and generalizable manner. © 2010 International Society for Advancement of Cytometry

Authors: Jiang Haizhen , Yuan Shijie , Wan Wen , Yang Kun , Deng Hongmei , Hao Jian 
Published: June 2010

AbstractOptically active 2‐aryl‐1,3‐oxazolines, such as aromaticcarbocycles, heterocycle‐binding 4‐benzyl (or phenyl)‐1,3‐oxazolines and their 5‐benzyl (or phenyl)‐1,3‐oxazoline isomers were successfully prepared through a bromotriphenylphosphonium salt promoted aziridine ring formation and ring opening sequential process involving tandem one‐pot cyclization of chiral 2‐amino‐3‐phenylpropanol or 2‐amino‐2‐phenylethanol with various aromatic acids in toluene at 90 °C in moderate to excellent yields. The mechanism of this tandem process was also substantiated experimentally.

Authors: Salimi Abdollah , Lasghari Saied , Noorbakhash Abdollah 
Published: June 2010

AbstractPotential cycling was used for oxidation of chloropromazine and producing an electroactive redox couples which strongly adsorbed on the electrode surface modified with carbon nanotubes and ionic liquid nanocomposite. The modified electrode shows excellent electrocatalytic activity toward NADH oxidation. The differential pulse voltammetry detection provided high sensitivity, 0.5835 A M−1, low detection limit, 80 nM at concentration range up to 20 μM. An ethanol biosensor was also developed by immobilizing alcohol dehydrogenase enzyme onto nanocomposite. Differential pulse voltammetric detection of ethanol gives linear responses over the concentration range 40 μM–1.5 mM with detection limit 5 μM and sensitivity 1.97 μA mM−1.
As(III) Determination in the Presence of Pb(II) by Differential Alternative Pulses Voltammetry
Authors: Zlatev Roumen , Stoytcheva Margarita , Valdez Benjamin 
Published: June 2010

AbstractDifferential Alternative Pulses Voltammetry (DAPV), introduced by the authors earlier, was applied with HMDE for direct As(III) determination in the presence of Pb(II) in natural water without sample pretreatment. Distinguishable peaks of As(III) and Pb(II) were registered in 1 M HCl supporting electrolyte at a concentration ratio as high as 1 : 6, while complete peak overlapping occurs applying DPP at any concentration ratio at the same experimental conditions. In‐situ As(III) determinations in the presence of Pb(II) in contaminated ground waters in Mexico were performed, using especially designed disposable safe mercury drop electrodes.
A New Type of Bismuth Electrode for Electrochemical Stripping Analysis Based on the Ammonium Tetrafluorobismuthate Bulk‐Modified Carbon Paste

Published: June 2010

AbstractA carbon paste electrode bulk‐modified with ammonium tetrafluorobismuthate (BiF4‐CPE) was developed and examined in the anodic stripping voltammetric mode for measurement of selected trace heavy metals. The BiF4‐CPE has revealed a favorable performance in more acidic solutions (pH 0.5–2.5) in the presence of dissolved oxygen for Cd(II) and Pb(II) as model metal ions at the low μg L−1 concentration level. In comparison with the bismuth‐oxide bulk‐modified carbon paste electrode and the other two bismuth film‐plated carbonaceous substrate electrodes examined, the BiF4‐CPE proved to be another attractive variant of the environmentally friendly bismuth‐based electrodes, particularly convenient for analysis of acidified water samples.
Analysis of historical landslide time series in the Emilia‐Romagna region, northern Italy
Authors: Rossi Mauro , Witt Annette , Guzzetti Fausto , Malamud Bruce D. , Peruccacci Silvia 
Published: June 2010

AbstractA catalogue of historical landslides, 1951–2002, for three provinces in the Emilia‐Romagna region of northern Italy is presented and its statistical properties studied. The catalogue consists of 2255 reported landslides and is based on historical archives and chronicles. We use two measures for the intensity of landsliding over time: (i) the number of reported landslides in a day (DL) and (ii) the number of reported landslides in an event (Sevent), where an event is one or more consecutive days with landsliding. From 1951–2002 in our study area there were 1057 days with 1 ≤DL≤?45 landslides per day, and 596 events with 1 ≤Sevent≤ 129 landslides per event. In the first set of analyses, we find that the probability density of landslide intensities in the time series are power‐law distributed over at least two‐orders of magnitude, with exponent of about −2·0. Although our data is a proxy for landsliding built from newspaper reports, it is the first tentative evidence that the frequency‐size of triggered landslide events over time (not just the landslides in a given triggered event), like earthquakes, scale as a power‐law or other heavy‐tailed distributions. If confirmed, this could have important implications for risk assessment and erosion modelling in a given area. In our second set of analyses, we find that for short antecedent rainfall periods, the minimum amount of rainfall necessary to trigger landslides varies considerably with the intensity of the landsliding (DLandSevent); whereas for long antecedent periods the magnitude is largely independent of the cumulative amount of rainfall, and the largest values of landslide intensity are always preceded by abundant rainfall. Further, the analysis of the rainfall trend suggests that the trigger of landslides in the study area is related to seasonal rainfall. Copyright © 2010 John Wiley & Sons, Ltd.
A new statistical method for detecting network anomalies in TCP traffic
Authors: Callegari Christian , Vaton Sandrine , Pagano Michele 
Published: June 2010

AbstractIn the last few years, the number and impact of security attacks over the Internet have been continuously increasing. To face this issue, the use of Intrusion Detection Systems (IDSs) has emerged as a key element in network security. In this paper we address the problem considering a novel statistical technique for detecting network anomalies. Our approach is based on the use of different families of Markovian models, namely high order and non‐homogeneous Markov chains, for modeling network traffic running over TCP. The performance results shown in the paper justify the proposed method and highlight the improvements over commonly used statistical techniques. Copyright © 2010 John Wiley & Sons, Ltd.
Equivalence of three score tests for association mapping of quantitative trait loci under selective genotyping
Authors: Tang Yongqiang 
Published: June 2010

AbstractHuang and Lin ([2007] Am J Hum Genet 80:567–572) proposed a conditional‐likelihood approach for mapping quantitative trait loci (QTL) under selective genotyping, and demonstrated via simulation that their model tends to be more powerful than the prospective linear regression. However, we show that the three score tests based on the conditional, prospective and retrospective likelihoods are numerically identical in testing association between a quantitative trait and a candidate locus. Two approximations are derived for calculating power and sample size for the score test. Compared to the random sampling, a single‐tail selection generally reduces the power of the score test in mapping small effect QTLs. A two‐tail selection generally enhances the QTL heritability; however, in small samples, the power of the test may actually decrease if the sample sizes are highly unbalanced in the upper and lower tails of the trait distribution.

Trends in column integrated water vapour over Europe from 1973 to 2003
Authors: Mattar Cristian , Sobrino José A. , Julien Yves , Morales Luis 
Published: June 2010

AbstractThe spatial and temporal variations of atmospheric precipitable water (PW) content anomalies were analysed over Europe from 1973 to 2003 using daily data (0000 and 1200 UTC) from National Center of Environmental Prediction and National Center of Atmospheric Research Reanalysis project (NCEP‐1) and in situ radiosonde data. Mann–Kendall trend tests were applied to long‐term PW time series. Technology changes influence PW radiosonde trends, although these are in agreement with NCEP‐1 trends. Over the south of the Iberian Peninsula, trends are negative and statistically significant (<− 0.04 mm year−1; p < 0.05) and positive over the Central European Mountains (The Alpes) and the North Atlantic Ocean (>0.04 mm year−1; p < 0.05). Seasonal trends revealed negative and significant trends over the Iberian Peninsula for all seasons (<− 0.03 mm year−1; p < 0.05). Copyright © 2010 Royal Meteorological Society
Relationship between human IgG structure and retention time in hydroxyapatite chromatography with sodium chloride gradient elution
Authors: Nakagawa Taishiro , Ishihara Takashi , Yoshida Hideaki , Yoneya Takashi , Wakamatsu Kaori , Kadoya Toshihiko 
Published: June 2010

AbstractAccurate prediction of the elution tendency of monoclonal antibodies in column chromatography would be beneficial for the efficient setup of purification procedures. Hydroxyapatite chromatography experiments using 37 recombinant human monoclonal antibodies were performed by sodium chloride gradient elution with 5 mM sodium phosphate to correlate the retention times with antibody structures (subclass and light‐chain isotypes). The contribution of metal affinity interactions in the interaction of antibodies with hydroxyapatite was investigated by (i) eliminating 5 mM sodium phosphate in buffers, (ii) comparing sodium chloride versus sodium phosphate gradient elutions, and (iii) using IgG4 antibodies with a leucine→glutamate mutation. By using antibodies of different subclasses but with identical Fab regions, the elution behavior in sodium chloride elution could be classified by subclass and type of light chain. It is considered that the retention of monoclonal antibodies to hydroxyapatite is affected by the cooperation of phosphoryl cation exchange and metal affinity interactions. The contribution of the metal affinity interactions is greater in the sodium chloride gradient elution method than in the sodium phosphate gradient elution method.
Optimized ultrasound‐assisted extraction procedure for the analysis of opium alkaloids in papaver plants by cyclodextrin‐modified capillary electrophoresis
Authors: Fakhari Ali Reza , Nojavan Saeed , Ebrahimi Samad Nejad , Evenhuis Christopher John 
Published: June 2010

AbstractThis study investigated the use of ultrasound‐assisted extraction to improve the extraction efficiency of morphine, codeine and thebaine from the papaver plants. Extraction conditions such as type of solvent, temperature, duration, frequency and power level of ultrasonic were optimized and the influences of different parameters on resolution of alkaloids in CE were studied. The optimized condition for CE separation includes a sodium phosphate buffer (100 mM, pH 3.0) containing 5 mM α‐CD. The optimized extraction conditions for ultrasound‐assisted extraction was an extraction time of 1 h, an ultrasonic frequency of 60 kHz with water–methanol (80:20) at 40°C as the extraction solvent. The LOD for alkaloids was found to be 0.1 μg/mL at a signal‐to‐noise ratio of 3:1. The RSDs for peak areas were in the range of 1.4–4.4%. The amounts of opium alkaloids (mg/100 g dried sample) in four Iranian papaver plants were found to be in the range of 7.8–8.7 (morphine), 5.5–9.5 (codeine) and 1.4–10.4 (thebaine). It should be emphasized that no cleanup of the filtered extract was required; hence, direct determination after extraction drastically simplifies the analytical process.
