Reducing the process lacuna in operational research by taking a knowledge work perspective
Authors: Keys Paul 
Published: July 2007

AbstractThe lack of concern in operational research (OR) with the processes that are associated with the work of analysts has recently been recognised as a ‘process lacuna’. However, the broader and related field of management and organisation studies contains elements upon which an understanding of these processes may be constructed. The focus of these elements is the understanding of knowledge and its use in organisations. In this paper these elements are identified, brought together, and shown to generate a means of reducing the process lacuna in OR, specifically by demonstrating how they enable an exploration of the character of knowledge in OR and the processes associated with its production, dissemination, and legitimisation.

Published: July 2007

AbstractDementia with Lewy bodies (DLB) is a progressive dementia frequently accompanied by psychotic symptoms. Similar symptoms can occur in Alzheimer's disease (AD) to a lesser extent. The use of neuroleptic medication to treat psychosis in both diseases is of modest efficacy and can induce severe adverse reactions in DLB. Dopamine D2 receptors in the cerebral cortex are the putative target for the antipsychotic action of these drugs, but the status of these receptors in DLB is unknown. Autoradiography was used to examine the density D2 receptors in postmortem temporal cortex tissue from prospectively assessed patients with neuropathologically confirmed DLB and AD. D2 receptors were substantially (over 40%) and significantly (P < 0.001) reduced in temporal cortex in DLB, and in DLB with concomitant Alzheimer pathology, but was not significantly changed in AD. This reduction correlated with greater cognitive decline (P < 0.01), but was not significantly related to visual or auditory hallucinations or delusions. D2 receptor density was inversely correlated with cortical Lewy body pathology in the neocortex (P < 0.001). The specific loss of D2 receptors associated with Lewy body pathology, in conjunction with our previous finding of low D2 receptors in striatum in DLB, provides a possible explanation for neuroleptic intolerance. That the reduction of D2 receptors correlated with cognitive decline suggests that neuroleptics, as dopamine D2 receptor antagonists, may have a deleterious effect on cognition in DLB.

(−)‐Epigallocatechin gallate, the most active polyphenolic catechin in green tea, presynaptically facilitates Ca2+‐dependent glutamate release via activation of protein kinase C in rat cerebral cortex

Published: July 2007

Abstract(−)‐epigallocatechin gallate (EGCG), the main polyphenolic constituent of green tea, has been reported to improve cognitive decline. Considering the central glutamatergic activity is crucial to cognitive function, the objective of this study was to investigate the effect of EGCG on the release of endogenous glutamate using nerve terminals purified from rat cerebral cortex. Results showed that the release of glutamate evoked by 4‐aminopyridine (4AP) was facilitated by EGCG in a concentration‐dependent manner, and this effect resulted from an enhancement of vesicular exocytosis and not from an increase in Ca2+‐independent efflux via glutamate transporter. Examination of the effect of EGCG on cytoplasmic free Ca2+ concentration ([Ca2+]c) revealed that the facilitation of glutamate release could be attributed to an increase in Ca2+ influx through N‐ and P/Q‐type voltage‐dependent Ca2+ channels. Consistent with this, the EGCG‐mediated facilitation of 4AP‐evoked glutamate release was significantly prevented in synaptosomes pretreated with a combination of the N‐ and P/Q‐type Ca2+ channel blockers. Additionally, inhibition of protein kinase C (PKC) by treatment with Ro318220 significantly reduced the facilitatory effect of EGCG on 4AP‐evoked glutamate release and phosphorylation of PKC or its presynapic target myristoylated alanine‐rich C kinase substrate (MARCKS). These results suggest that EGCG effects a facilitation of glutamate release from glutamatergic terminals by positively modulating N‐ and P/Q‐type Ca2+ channel activation through a signaling cascade involving PKC. In this EGCG/PKC signaling cascade facilitating glutamate release, the regulation of cytoskeleton dynamics was also indicated to be involved by disruption of cytoskeleton organization with cytochalasin D occluded the EGCG‐mediated facilitation of 4AP‐evoked glutamate release.

Electrochemical functions of metallosupramolecular nanomaterials
Authors: Higuchi Masayoshi , Kurth Dirk G. 
Published: July 2007

AbstractSelf‐assembly of metal ions and organic ligands results in the formation of extended or discrete metallosupramolecular structures. In case of neutral ditopic ligands such as bisterpyridines, extended metallosupramolecular coordination polyelectrolytes (MEPEs) are formed. Metal ion‐induced self‐assembly of 1,4‐bis(2,2′:6′,2″‐terpyridin‐4′‐yl)benzene with Fe(II) or Co(II) results in MEPEs with interesting electrochemical properties. These MEPEs reversibly change their color when oxidized or reduced. The heterometallic MEPE consisting of Fe(II) and Co(II) combines the properties of the individual MEPEs and therefore shows their different states: red‐purple, blue, and transparent. On the other hand, complexation of cyclic phenylazomethines with metal ions results in discrete metallosupramolecular structures. We find that metal ion assembly to the organic module occurs in a stepwise fashion because of a difference in the basicity of the imine conformers, and the metal ion assembly can be controlled electrochemically. This example illustrates how metal ion binding can be controlled by the conformation of the receptor, an important step toward assembling organic ligands and metal ions in predictable ways. © 2007 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.

Chromosome protein framework from proteome analysis of isolated human metaphase chromosomes
Authors: Fukui Kiichi , Uchiyama Susumu 
Published: July 2007

AbstractWe have presented a structural model of the chromosome based on its constituent proteins. Development of a method of mass isolation for intact human metaphase chromosomes and proteome analysis by mass spectrometry of the isolated chromosomal proteins enabled us to develop a four‐layer structural model of human metaphase chromosomes. The model consists of four layers, each with different chromosomal protein sets, i.e., chromosome coating proteins (CCPs), chromosome peripheral proteins (CPPs), chromosome structural proteins (CSPs), and chromosome fibrous proteins (CFPs). More than 200 identified proteins have been classified and assigned to the four layers with each layer occupying a distinct region of the chromosome. CCPs are localized at the most outer regions of the chromosomes and they attach to the regions tentatively and occasionally. CCPs include mostly mitochondrial and cytoplasmic proteins, e.g., 70 kDa heat shock protein 9B and Hsp60. CPPs are also localized at the peripheral regions of the chromosomes, but as the essential part of the chromosomes. CPPs include nucleolin, lamin A/C, fibrillarin, etc. CSPs are the primary chromosomal structure proteins, and include topoisomerase IIα, condensin subunits, histones, etc. CFPs have a fibrous nature, e.g., β‐actin, vimentin, myosin II, tublin, etc. A data set of these proteins, which we developed, contains essential chromosome proteins with classified information based on this four‐layer model and presents useful leads for further studies on chromosomal structure and function. © 2007 The Japan Chemical Journal Forum and Wiley Periodicals, Inc.

Published: July 2007

AbstractObjectiveTo evaluate changes in the temporal evolution and regional distribution of arterial brain Doppler parameters in relation to different stages of hemodynamic adaptation in fetuses with severe intrauterine growth restriction (IUGR).MethodsThirty‐six fetuses with severe IUGR (≤ 32 weeks of gestation) and abnormal umbilical artery (UA) pulsatility index (PI) (mean > 2 SD) were evaluated longitudinally with pulsed Doppler ultrasound at four different hemodynamic stages: Stage 1 (n = 36), mean UA‐PI > 2 SD or absent UA end‐diastolic flow; Stage 2 (n = 34), abnormal middle cerebral artery (MCA) PI (mean < 2 SD); Stage 3 (n = 30), reversed UA end‐diastolic flow; Stage 4 (n = 12), absent or reversed atrial flow in the ductus venosus. In addition, 36 normally grown fetuses were studied for comparison. PI and time‐averaged maximum velocity (TAMXV) in the MCA and the anterior cerebral (ACA), pericallosal (PER) and posterior cerebral (PCA) arteries were measured.ResultsIn IUGR fetuses, PI values from all arteries were significantly reduced at Stage 2. At Stages 3 and 4, ACA‐PI and PCA‐PI did not change further, whereas MCA‐PI and PER‐PI showed a slight increase. In the ACA, MCA and PER, TAMXV in Stage 2 increased significantly. In Stages 3 and 4, ACA and PER‐TAMXV remained unchanged, whereas MCA‐TAMXV showed a slight decrease, mirroring the PI values. PCA‐TAMXV values were similar to controls at all stages.ConclusionIn IUGR fetuses, the brain arteries differ in the magnitude and time sequence of Doppler parameters in relation to systemic hemodynamic adaptation, suggesting the existence of regional brain redistribution processes.

Dimorphic ErAgSn and TmAgSn – High‐Pressure and High‐Temperature Driven Phase Transitions
Authors: Sebastian C. Peter , Heymann Gunter , Heying Birgit , Rodewald Ute Ch. , Huppertz Hubert , Pöttgen Rainer 
Published: July 2007

AbstractThe stannides ErAgSn and TmAgSn have been investigated under high‐temperature (HT) and high‐pressure (HP) conditions in order to investigate their structural chemistry. ErAgSn and TmAgSn are dimorphic: normal‐pressure (NP) ErAgSn and HT‐TmAgSn crystallize into the NdPtSb type structure, P63mc, a = 466.3(1), c = 729.0(2) pm for NP‐ErAgSn and a = 465.4(1), c = 726.6(2) pm for HT‐TmAgSn. NP‐ErAgSn was obtained via arc‐melting of the elements and subsequent annealing at 970 K, while HT‐TmAgSn crystallized directly from the melt by rapidly quenching the arc‐melted sample. HT‐TmAgSn transforms to the ZrNiAl type low‐temperature modification upon annealing at 970 K. The high‐pressure (HP) modification of ErAgSn was synthesized under multianvil high‐pressure (11.5 GPa) high‐temperature (1420 K) conditions from NP‐ErAgSn: ZrNiAl type, $P{\bar 6}{\rm 2}m$, a = 728.7(2), c = 445.6(1) pm. The silver and tin atoms in NP‐ErAgSn and HT‐TmAgSn build up two‐dimensional, puckered [Ag3Sn3] networks (277 pm intralayer Ag–Sn distance in NP‐ErAgSn) that are charge‐balanced and separated by the erbium and thulium atoms. The fourth neighbor in the adjacent layer has a longer Ag–Sn distance of 298 pm. The [AgSn] network in HP‐ErAgSn is three‐dimensional. Each silver atom has four tin neighbors (281–285 pm Ag–Sn). The [AgSn] network leaves distorted hexagonal channels, which are filled with the erbium atoms. The crystal chemistry of the three phases is discussed.

AbstractA new aluminophosphite (H4bape)0.5[Al(OH)(HPO3)2] has been synthesized under hydrothermal conditions and its structure was determined by single‐crystal X‐ray diffraction (bape = N,N′‐bis(2‐aminopropyl)ethylenediamine). This compound crystallizes in the triclinic system with the space group $P{\bar 1}$ (No. 2), a = 6.919(2) Å, b = 8.704(2) Å, c = 9.786(2) Å, α = 77.74(3)°, β = 72.43(3)°, γ = 72.52(3)°, V = 531.08(2) Å3, Z = 2. The structure consists of distorted octahedral AlO6 and pseudo pyramidal HPO3, which are connected by vertex oxygen atoms to form a chainlike framework with a Al/P ratio of 1/2. The presence of 1D infinite Al‐O‐Al linkage in the framework is noteworthy. The organic templates are fully protonated and interact with the aluminophosphite chains through extensive hydrogen bonds to form a 3D supramolecular network.

The compounds with Ln = Y (a = 28.390(2), b = 10.068(1), c = 33.715(2) Å, β = 113.85(1)°), Gd (a = 28.327(2), b = 10.074(1), c = 33.822(2) Å, β = 114.297(7)°), Dy (a = 28.124(6), b = 10.003(2), c = 33.486(7) Å, β = 113.89(3)°), Yb (a = 28.178(3), b = 9.977(1), c = 33.392(4) Å, β = 113.65(1)°), and Lu (a = 28.169(6), b = 10.002(2), c = 33.432(7) Å, β = 113.54(3)°) are isotypic and crystallize in a new structure type (C2/c; Z = 12). Main feature are PS4 tetrahedra isolated from each other surrounding the Ln and Li atoms via their S atoms. The coordination number of the five crystallographically independent Ln atoms is eight, but the polyhedra are quite different and they are interlinked to larger units extending in [010]. The environment of the Li atoms is irregular and formed by five to six S atoms. The crystal structure is compared with that of Li9Ln2(PS4)5 (Ln: Nd, Gd). For the synthesis of Ag3Y(PS4)2 (a = 16.874(3), b = 9.190(2), c = 9.312(2) Å, β = 123.17(3)°) a mixture of Y, P, S, and Ag2S was heated to 700 °C (50 h). The thiophosphate crystallizes in a new structure type (C2/c; Z = 4) composed of isolated PS4 tetrahedra. The two crystallographically independent Ag atoms are surrounded by four S atoms in the shape of distorted tetrahedra. The Ag(1)S4 polyhedra are cornershared to strands running along [001], which are linked together via Ag(2)S4 tetrahedra. The environment of the Y atoms is composed of eight S atoms each building distorted square antiprisms. These polyhedra are connected with each other via common edges to a strand running along [001].

Abstract[Mn(H2O)4(C4N2H4)][C6H4(COO)2] – An One‐Dimensional Coordination Polymer with Chain‐like [Mn(H2O)4(C4N2H4)]n2n+ PolycationsOrthorhombic single crystals of [Mn(H2O)4(C4N2H4)][C6H4(COO)2] have been prepared in aqueous solution at room temperature. Space group Imm2 (no. 44), a = 1039.00(6) pm, b = 954.46(13) pm, c = 737.86(5) pm, V = 0.73172(12) nm3, Z = 2. Mn2+ is coordinated in a octahedral manner by four water molecules and two nitrogen atoms stemming from the pyrazine molecules (Mn–O 215.02(11) pm; Mn–N 228.7(4), 230.7(4) pm). Mn2+ and pyrazine molecules form chain‐like polycations with [Mn(H2O)4(C4N2H4)]n2n+ composition. The positive charge of the polycationic chains is compensated for by phthalate anions, which are accomodated between the chains. The phthalate anions are linked by hydrogen bonds to the polycationic chains. Thermogravimetric analysis in air revealed that the loss of water of crystallisation and pyrazine occurs in two steps between 130 and 245 °C. The resulting sample was stable up to 360 °C. Further decomposition yielded Mn2O3.

In contrast, the triple decker cation found in (7) is less common. The crystal structures are completed by mostly asymmetrically linear I3− anions.

AbstractThe Tetracyanoboronic Acids H[B(CN)4]·n H2O, n = 0, 1, 2Treatment of an aqueous solution of Na[B(CN)4] with an acidic cation exchange resin leads to a solution of the strong tetracyanoboronic acid. Evaporation of the solution at room temperature yields colourless single crystals of [H5O2][B(CN)4] ($P{\bar 4}n {\rm 2}$, a = 9.5830(2) Å, c = 14.25440(3) Å, Z = 1). Further drying of [H5O2][B(CN)4] (mp. 115 °C) in vacuum at 50 °C gives polycrystalline [H3O][B(CN)4] (P63mc, a = 8.704(1) Å, c = 6.152(1) Å, Z = 2), which is thermally stable up to 145 °C. The anhydrous polycrystalline acid H[B(CN)4] is formed quantitatively by reacting Me3SiNCB(CN)3 with gaseous HCl. This acid starts to decompose at 190 °C with loss of HCN. All three acids were further characterized by vibrational spectroscopy, and elemental analysis.

Published: July 2007

AbstractSingle crystals of AgVSeO5 and AgVTeO5 were obtained under hydrothermal conditions at 190 °C by reacting stoichiometric amounts of AgNO3, NaVO3, TeO2 and SeO2, respectively. AgVSeO5 crystallizes in Pbcm with a = 418.14(3) pm, b = 2007.70(6) pm, c = 521.17(2) pm, V = 437.52(2) × 106 pm3 and Z = 4, as red needles. The structure consists of VO5 square pyramids, trigonal SeO3 pyramids and AgO8 polyhedra, as primary building units. The VO5 square pyramids are linked to chains running along the c‐axis, by sharing oxygen atoms in the basal plane in cis‐position. The remaining basal O atoms of the VO5 moieties are shared with two oxygen atoms of the SeO3 units. The resulting polyanionic strands of composition [VSeO5]− are interconnected by silver atoms to form a three dimensional network. AgVTeO5 crystallizes as yellow needles in P21/c with a = 586.59(1) pm, b = 1137.98(2) pm, c = 680.78(1) pm, β = 102.733(1)°, V = 443.26(1) × 106 pm3 and Z = 4. The structure consists of VO4 tetrahedra, Ψ‐trigonal‐bipyramidal TeO4 units and AgO8 polyhedra as primary building units. The TeO4 groups form dimers by edge sharing, which are linked through vertices to the VO4 tetrahedra. The resulting one dimensional polyanion is extending along [101]. The structural motifs and charge distribution according to Se4+/V5+, and Te4+/V5+ respectively, seem to allow for a reshuffling of the charge distribution, thus inducing interesting physical phenomena, at elevated temperatures or pressures.

AbstractThe reaction of 2‐amino‐benzothiazole with allyl bromide resulted in a mixture of 2‐imino‐3‐allyl‐benzothiazole and 2‐imino‐3‐allyl‐benzothiazolium bromide.Using such a mixture and copper(II) chloride in acetonitrile solution in alternating‐current electrochemical synthesis crystals of the [(CuCl)C10H10SN2] (I) have been obtained. The same procedure, performed in ethanol solution, has led to formation of [C10H11SN2+]2[Cu2Cl4]2− (II). In the same manner the bromine derivative [C10H11SN2+]2[Cu2Br4]2− (III) has been synthesized. All three compounds were X‐ray structurally investigated. I:monoclinic space group P21/n, a = 13.789(6), b = 6.297(3), c = 13.830(6) Å, β = 112.975(4)°, V = 1105.6 (9) Å3, Z = 4 for CuCl·C10H10 SN2 composition. Compounds II and III are isomorphous and crystallize in triclinic $\rm P{\bar 1}$ space group. II a = 7.377(3), b = 8.506(3), c = 9.998(4) Å, α = 79.892(10)°, β = 82.704(13)°, γ = 78.206(12)°, V = 601.9(4) Å3, Z = 1. III a = 7.329(2), b = 8.766(3), c = 10.265(3) Å, α = 79.253(9)°, β = 82.625(9)°, γ = 77.963(9)°, V = 630.9(3) Å3, Z = 1. In the structure I [(CuCl)C10H10SN2] building blocks are bound into infinitive spiral‐like chains via strong N‐H..Cl hydrogen bonds. In the zwitter‐ionic II and III compounds copper and halide atoms form centrosymmetric [Cu2X4]2− anions, which are interconnected via N‐H..X hydrogen bonds into infinite butterfly‐like chains. The strongest Cu‐(C=C) π‐interaction has been observed in structure I, where copper possesses coordination number 3. Increasing copper coordination number to 4 in II as well as replacing chlorine atoms by bromine ones in III suppresses markedly this interaction.
