Collaborative Intelligence = Respect
Authors: Kaseman Keith
Published: March 2009

Cultural projects today are often unprecedented in their complexity, scale and collaborative effort. Keith Kaseman, partner of Kaseman Beckman Advanced Strategies (KBAS), describes how building information modelling (BIM) enabled the realisation of the Pentagon Memorial in Arlington, Virginia. Twenty‐eight contractors and consultants were brought on board in the design and delivery of the monument's 184 ‘memorial units’, which collectively commemorate the individual lives lost at the Pentagon on 11 September 2001.
Electrically Conductive Thin Films Prepared from Layer‐by‐Layer Assembly of Graphite Platelets
Authors: Alazemi Mubarak , Dutta Indrajit , Wang Feng , Blunk Richard H. , Angelopoulos Anastasios P.
Published: March 2009

Layer‐by‐layer (LBL) assembly of carbon nanoparticles for low electrical contact resistance thin film applications is demonstrated. The nanoparticles consist of irregularly shaped graphite platelets, with acrylamide/ββ‐methacryl‐oxyethyl‐trimethyl‐ammonium copolymer as the cationic binder. Nanoparticle zeta (ζζ) potential and thereby electrostatic interactions are varied by altering the pH of graphite suspension as well as that of the binder suspension. Film thickness as a function of zeta potential, immersion time, and the number of layers deposited is obtained using Monte Carlo simulation of the energy dispersive spectroscopy measurements. Multilayer film surface morphology is visualized via field‐emission scanning electron microscopy and atomic‐force microscopy. Thin film electrical properties are characterized using electrical contact resistance measurements. Graphite nanoparticles are found to self‐assemble onto gold substrates through two distinct yet overlapping mechanisms. The first mechanism is characterized by logarithmic carbon uptake with respect to the number of deposition cycles and slow clustering of nanoparticles on the gold surface. The second mechanism results from more rapid LBL nanoparticle assembly and is characterized by linear weight uptake with respect to the number of deposition cycles and a constant bilayer thickness of 15 to 21 nm. Thin‐film electrical contact resistance is found to be proportional to the thickness after equilibration of the bilayer structure. Measured values range from 1.6 mΩ cm−2 at 173 nm to 3.5 mΩ cm−2 at 276 nm. Coating volume resistivity is reduced when electrostatic interactions are enhanced during LBL assembly.
Self‐Assembly of a Four‐Helix Bundle on a DNA Quadruplex
Authors: Rosenzweig Brooke A. , Hamilton Andrew D.
Published: March 2009

Come together: A novel method for assembling monomers and controlling structure of a de novo helix bundle protein is described. A guanine (G)‐rich oligodeoxynucleotide scaffold forms a hydrogen‐bonded DNA quadruplex in the presence of potassium counterions, thereby inducing a helical structure and fourfold stoichiometry in conjugated, amphiphilic peptide sequences. The DNA scaffold shows potential for rapidly assembling designed proteins.

Sonochemical Synthesis of Highly Luminescent Zinc Oxide Nanoparticles Doped with Magnesium(II)
Authors: Xiong Huan‐Ming , Shchukin Dmitry G. , Möhwald Helmuth , Xu Yang , Xia Yong‐Yao
Published: March 2009

A bright idea: Mg/ZnO nanoparticles that exhibit bright, stable photoluminescence both in colloidal dispersions and in the solid state are formed by doping MgII ions into ZnO nanoparticles by sonochemical synthesis. The changes in their band gaps and luminescence properties rely on the defect concentrations inside the ZnO nanoparticles; these concentrations are determined by the Mg/Zn molar ratios (see picture).

Photomagnetic Switching of the Complex [Nd(dmf)4(H2O)3(μ‐CN)Fe(CN)5]⋅H2O Analyzed by Single‐Crystal X‐Ray Diffraction
Authors: Svendsen Helle , Overgaard Jacob , Chevallier Marie , Collet Eric , Iversen Bo B.
Published: March 2009

X‐ray vision: Single‐crystal XRD experiments (see picture) reveal the excited‐state structure of the photomagnetic heterobimetallic title complex. The system shows a decrease in all the iron–ligand bond lengths, suggesting that photoexcitation involves a ligand‐to‐metal charge transfer or a change in the superexchange coupling between the metal centers.

Modification of polypropylene and polypropylene/ fibrous cellulose composites by the addition of poly(ethylene oxide)
Authors: Nakatani Hisayuki , Miyazaki Kensuke
Published: March 2009

Effects of the addition of poly(ethylene oxide) (PEO) on the tensile properties of a polypropylene (PP)/fibrous cellulose (FC) composite were studied. PEO was incompatible with the PP matrix, and a PP/PEO blend showed a sea‐island morphology. However, the existence of the PEO phase hardly impaired the ductility of PP, leading to a strain constraint relaxation resulting from void formation in the phase. The tensile behavior of PP/PEO was little affected by the content (until 10 wt %) or molecular weight of PEO. The results suggested that the PEO phase was able to be deformed in a slit‐like shape and had no interaction with the PP matrix. Effects of PEO on the morphology and tensile and fracture behavior of the PP/FC composite with maleated polypropylene (MAPP) as a compatibilizer critically depended on the preparation method. In the case of the addition of PEO to PP/FC/MAPP, increases in the strain and fracture energy were observed in comparison with PP/FC. In the case of the addition of FC/PEO to PP/MAPP, although the obtained composite showed a lower Young's modulus and tensile strength in comparison with PP/FC, the strain and fracture energy were considerably increased by the existence of the PEO layer coating the FC. © 2009 Wiley Periodicals, Inc.

Fluoroalkyl end‐capped oligomer possessing a nonflammable characteristic in silica gel matrices even at 800°C under atmospheric conditions
Authors: Sawada Hideo , Kakehi Hiroshi , Tashima Tsukasa , Nishiyama Yusuke , Miura Masashi , Isu Norifumi
Published: March 2009

We succeeded in observing the similar solid‐state NMR spectra (1H‐magic‐angle spinning NMR spectra) of fluoroalkyl end‐capped N‐(1,1‐dimethyl‐3‐oxobutyl)acrylamide oligomer [RF‐(DOBAA)n‐RF]/silica gel nanocomposite before and even after calcinations at 800°C. This finding suggests that RF‐(DOBAA)n‐RF oligomer in RF‐(DOBAA)n‐RF/silica gel nanocomposite can afford a nonflammable characteristic to exhibit no weight loss behavior even at 800°C under atmospheric conditions. In addition, we had good oleo‐ and hydrophobic characteristics on the modified glass surface treated with RF‐(DOBAA)n‐RF/silica gel nanocomposite even after calcination at 800°C as well as those before calcinations. Especially, RF‐(DOBAA)n‐RF/silica gel nanocomposite‐encapsulated cetylpyridinium chloride (CPC) possessing no weight loss characteristic even at 800°C exhibited a clear UV–vis absorption band around 260 nm related to the presence of CPC before and even after calcinations at 800°C. © 2009 Wiley Periodicals, Inc.

A particle swarm optimization‐driven cognitive map approach to analyzing information systems project risk
Authors: Chang Lee Kun , Lee Namho , Li Honglei
Published: March 2009

Project risks encompass both internal and external factors that are interrelated, influencing others in a causal way. It is very important to identify those factors and their causal relationships to reduce the project risk. In the past, most IT companies evaluate project risk by roughly measuring the related factors, but ignoring the important fact that there are complicated causal relationships among them. There is a strong need to develop more effective mechanisms to systematically judge all factors related to project risk and identify the causal relationships among those factors. To accomplish this research objective, our study adopts a cognitive map (CM)‐based mechanism called the MACOM (Multi‐Agents COgnitive Map), where CM is represented by a set of multi‐agents, each embedded with basic intelligence to determine its causal relationships with other agents. CM has proven especially useful in solving unstructured problems with many variables and causal relationships; however, simply applying CM to project risk management is not enough because most causal relationships are hard to identify and measure exactly. To overcome this problem, we have borrowed a multi‐agent metaphor in which CM is represented by a set of multi‐agents, and project risk is explained through the interaction of the multi‐agents. Such an approach presents a new computational capability for resolving complicated decision problems. Using the MACOM framework, we have proved that the task of resolving the IS project risk management could be systematically and intelligently solved, and in this way, IS project managers can be given robust decision support.

Published: March 2009

A simple and rapid HPLC method using fluorescence detection was developed for determination of irbesartan in human plasma. Sample preparation was accomplished through a simple deproteinization procedure with 0.4 mL of acetonitrile containing 800 ng/mL of losartan (internal standard), and to a 0.1 mL plasma sample. Chromatographic separation was performed on a Zorbax Xclipse XDB C18column (150 × 4.6 mm, i.d., 5 µm) at 40°C. An isocratic mobile phase, acetonitrile:0.1% formic acid (37:63, v/v), was run at a flow‐rate of 1.0 mL/min, and the column eluent was monitored using a fluorescence detector set at excitation and emission wavelengths of 250 and 370 nm, respectively. The retention times of irbesartan and losartan were 4.4 and 5.9 min, respectively. This assay was linear over a concentration range of 10–5000 ng/mL with a lower limit of quantification of 10 ng/mL. The coefficient of variation for this assay precision was less than 8.48%, and the accuracy exceeded 94.4%. The mean relative recoveries of irbesartan and losartan were 98.4 and 99.1%, respectively. This method was successfully applied for pharmacokinetic study after oral administration of irbesartan (300 mg) to 23 Korean healthy male volunteers. Copyright © 2009 John Wiley & Sons, Ltd.

Published: March 2009

Phyllanthus niruri L., commonly known in Brazil as ‘quebra‐pedra’, has long been used in the treatment of diverse diseases and especially urolithiasis. The therapeutic effects of P. niruri are attributed to various compounds present in the plant, including the hydrolysable tannin corilagin. In the present study, high‐performance liquid chromatography (HPLC‐/PAD) profiles of leaves and commercial extracts of P. niruri were examined and three compounds, found to be present in all of the samples studied, were isolated by open column chromatography over C18 silica gel followed by preparative HPLC. These compounds were identified by nuclear magnetic resonance as corilagin, rutin and ethyl 3,4,5‐trihydroxybenzoate. Corilagin, which has been proposed as a phytochemical marker for P. niruri, was employed as an external standard in the development and validation of a rapid and efficient qualitative and quantitative HPLC assay for the analyte. The method may be applied in the standardization of herbs and phytomedicines commercialized in Brazil as quebra‐pedra. Copyright © 2009 John Wiley & Sons, Ltd.
Identification of 1‐palmitoyl‐2‐linoleoyl‐phosphatidylethanolamine modifications under oxidative stress conditions by LC‐MS/MS
Authors: Domingues M. Rosário M. , Simões Cláudia , da Costa João Pinto , Reis Ana , Domingues Pedro
Published: March 2009

Phosphatidylethanolamines are a major class of phospholipids found in cellular membranes. Identification of the alterations in these phospholipids, induced by free radicals, could provide new tools for in vivo diagnosis of oxidative stress. In this study, 1‐palmitoyl‐2‐linoleoyl‐phosphatidylethanolamine oxidation products, induced by the hydroxyl radical, were studied using LC‐MS and LC‐MS/MS. Data obtained allowed the identification and separation of isomeric oxidative products with modifications in the sn‐2 acyl chain, attributed to long‐ and short‐chain products. Among long‐chain products keto, keto‐hydroxy, hydroxy, poly‐hydroxy, peroxy and hydroxy–peroxy derivatives were identified. Product ions formed by loss of two H2O molecules vs loss of HOOH, allowed the identification of, respectively, di‐ (or poli‐) hydroxy vs peroxy derivatives. Location of functional groups was determined by the product ions formed by cleavage of C–C bonds, in the vicinity of the oxidation positions, allowing the identification of C9, C12 and C13 as the predominant substituted positions. Short‐chain products identified comprised aldehydes, hydroxy‐aldehydes and carboxylic derivatives, with modified sn‐2 acyl lengths of C7–C9 and C11, C12. Among the short‐chain products identified, C9 products showed higher relative abundance. Copyright © 2009 John Wiley & Sons, Ltd.
The effect ofN‐acetylcysteine on amphetamine‐mediated dopamine release in rat brain striatal slices by ion‐pair reversed‐phase high performance liquid chromatography
Authors: Gere‐Pászti Erzsébet , Jakus Judit
Published: March 2009

The amphetamine (AMPH)‐induced alteration in rat brain dopamine levels modified byN‐acetylcysteine (NAC) administration has been examined using isocratic ion‐pair reversed‐phase high‐performance liquid chromatography with electrochemical detection. The aim of the development of a novel validated evaluation scheme implying a double AMPH challenge was to enhance the efficiency of AMPH‐triggered dopamine release measurements in rat brain striatal slices by improving the reproducibility of the results. The proposed experimental protocol was testedin vivoand proved to be capable of fast and reliable drug screening for tracing the effect of NAC as a model compound in AMPH‐mediated dopaminergic response. The subcellular localization of the dopamine mobilizing effect of NAC has been established indirectly by the use of an irreversible dopamine vesicular depletor, reserpine. The antioxidant NAC at 10 mmplays an important role in the complete suppression of acute AMPH‐elicited dopamine release. The possible role of this quenching effect is discussed.

Search for a target image area based on geometrical parameters of multiple future pixels
Authors: Matuura Yosihumi , Saitoh Fumihiko
Published: March 2009

This paper proposes a method of measuring the two‐dimensional pose of an object by means of a voting process based on the geometrical parameters of selected future pixels. The proposed method can measure the location and inclination of an object even if the object has an arbitrary two‐dimensional pose in an image. In the template registration process, the geometrical parameters of multiple selected future pixels are registered in the template table. In the matching process, a target image area with a figure similar to a template image is sought by using the geometrical parameters of the future pixels. Experimental results show that the poses of objects with arbitrary locations and inclinations were recognized successfully by the proposed method with higher‐speed matching than by conventional methods. © 2009 Wiley Periodicals, Inc.

Direct products of automorphism groups of graphs
Authors: Grech Mariusz
Published: March 2009

In this article we study the product action of the direct product of automorphism groups of graphs. We generalize the results of Watkins [J. Combin Theory 11 (1971), 95–104], Nowitz and Watkins [Monatsh. Math. 76 (1972), 168–171] and W. Imrich [Israel J. Math. 11 (1972), 258–264], and we show that except for an infinite family of groups Sn × Sn, n≥2 and three other groups D4 × S2, D4 × D4 and S4 × S2 × S2, the direct product of automorphism groups of two graphs is itself the automorphism group of a graph. © 2009 Wiley Periodicals, Inc.

Creating a better discharge summary: Improvement in quality and timeliness using an electronic discharge summary
Authors: O'Leary Kevin J. , Liebovitz David M. , Feinglass Joseph , Liss David T. , Evans Daniel B. , Kulkarni Nita , Landler Matthew P. , Baker David W.
Published: March 2009

BACKGROUND:

Deficits in information transfer between inpatient and outpatient physicians are common and potentially dangerous.

OBJECTIVE:

To evaluate the effect of a newly‐created electronic discharge summary.

DESIGN AND PARTICIPANTS:

Pre‐post evaluation of discharge summaries using a survey of outpatient physicians and a medical records review.

MEASUREMENTS:

Outpatient physicians' ratings of satisfaction with discharge summaries before and after implementation of an electronic discharge summary using a 5‐point Likert scale (1 = very dissatisfied; 5 = very satisfied). Additionally, 196 randomly selected discharge summaries before and after implementation were rated for timeliness and presence of 16 key content areas by 3 internists.

RESULTS:

Two hundred and twenty‐six of 416 (54%) and 256 of 397 (64%) outpatient physicians completed the baseline and postimplementation surveys. Satisfaction with quality and timeliness of discharge summaries improved with the use of the electronic discharge summary (mean quality rating 3.04 versus 3.64; P < 0.001, mean timeliness rating 2.59 versus 3.34; P < 0.001). A higher percentage of electronic discharge summaries were completed within 3 days of discharge as compared with dictated discharge summaries (44.8% versus 74.1%; P < 0.001). Several elements of the discharge summary were present more often with the electronic discharge summary, including discussion of follow‐up issues (52.0% versus 75.8%; P = 0.001), pending test results (13.9% versus 46.3%; P < 0.001), and information provided to the patient and/or family (85.1% versus 95.8%; P = 0.01).

CONCLUSIONS:

The use of an electronic discharge summary significantly improved the quality and timeliness of discharge summaries. Journal of Hospital Medicine 2009;4:219–225. © 2009 Society of Hospital Medicine.
Complex plastic changes in the neuropeptide Y system during ethanol intoxication and withdrawal in the rat brain
Authors: Olling J.D. , Ulrichsen J. , Christensen D.Z. , Woldbye D.P.D.
Published: March 2009

Previous studies show that chronic ethanol treatment induces prominent changes in brain neuropeptide Y (NPY). The purpose of the present study was to explore ethanol effects at a deeper NPY‐system level, measuring expression of NPY and its receptors (Y1, Y2, Y5) as well as NPY receptor binding and NPY‐stimulated [35S]GTPγS functional binding. Rats received intragastric ethanol repeatedly for 4 days, and the NPY system was studied in the hippocampal dentate gyrus (DG), CA3, CA1, and piriform cortex (PirCx) and neocortex (NeoCx) during intoxication, peak withdrawal (16 hr), late withdrawal (3 days), and 1 week after last ethanol administration. NPY mRNA levels decreased during intoxication and at 16 hr in hippocampal regions but increased in the PirCx and NeoCx at 16 hr. NPY mRNA levels were increased at 3 days and returned to control levels in most regions at 1 week. Substantial changes also occurred at the receptor level. Thus Y1, Y2, and Y5 mRNA labelling decreased at 16 hr in most regions, returning to control levels at 3 days, except for PirCx Y2 mRNA, which increased at 3 days and 1 week. Conversely, increases in NPY receptor binding occurred in hippocampal regions during intoxication and in functional binding in the DG and NeoCx during intoxication and at 16 hr and in PirCx during intoxication and at 1 week. Thus this study shows that ethanol intoxication and withdrawal induce complex plastic changes in the NPY system, with decreased/increased gene expression or binding occurring in a time‐ and region‐specific manner. These changes may play an important role in mediating ethanol‐induced changes in neuronal excitability. © 2009 Wiley‐Liss, Inc.
Is there an indication for initial conservative management of pancreatic cystic lesions?
Authors: Grobmyer Stephen R. , Cance William G. , Copeland Edward M. , Vogel Stephen B. , Hochwald Steven N.
Published: March 2009

Background

The management of small pancreatic cystic lesions presents a clinical challenge.

Methods

We reviewed our experience with 78 patients who presented with a cystic pancreatic lesion who underwent operative management between 1995 and 2005. Data on cyst characteristics were analyzed in the context of pathologic findings following resection.

Results

Among 78 patients, there were 55 (71%) females; median age 63 years. Patients presented with: an incidental finding (48%), pain (40%), acute pancreatitis (4%), other (8%). Operations were distal pancreatectomy (n = 47), pancreaticoduodenectomy (n = 16), and other (n = 15). Most patients had a non‐malignant lesion (n = 65, 83%) (mucinous cystadenoma (n = 29), serous cystadenoma (n = 15), IPMN without invasion (n = 8), pseudocyst (n = 8), other benign (n = 5)). Malignant lesions (adenocarcinoma, neuroendocrine tumor, and other) were found in 13 patients (17%). The risk of malignancy increased with size: <3 cm (n = 25), 4%; 3–5 cm (n = 23), 13%; and >5 cm (n = 30), 30%. Pre‐operative cyst fluid cytology was performed in 41 patients. The negative predictive value (NPV) of cytology for malignancy was 88% and the positive predictive value (PPV) was 80%. The NPV of CA 19‐9 for malignancy was 90%; the PPV was 50%.

Conclusions

Initial conservative management of small cystic pancreatic lesions may be indicated in selected patients. J. Surg. Oncol. 2009;100:372–374. © 2009 Wiley‐Liss, Inc.
