A central role for the WH2 domain of Srv2/CAP in recharging actin monomers to drive actin turnover in vitro and in vivo
Authors: Chaudhry Faisal , Little Kristin , Talarico Lou , Quintero‐Monzon Omar , Goode Bruce L. 
Published: January 2010

AbstractCellular processes propelled by actin polymerization require rapid disassembly of filaments, and then efficient recycling of ADF/cofilin‐bound ADP‐actin monomers back to an assembly‐competent ATP‐bound state. How monomer recharging is regulated in vivo is still not well understood, but recent work suggests the involvement of the ubiquitous actin‐monomer binding protein Srv2/CAP. To better understand Srv2/CAP mechanism, we explored the contribution of its WH2 domain, the function of which has remained highly elusive. We found that the WH2 domain binds to actin monomers and, unlike most other WH2 domains, exhibits similar binding affinity for ATP‐actin and ADP‐actin (Kd ∼ 1.5 μM). Mutations in the WH2 domain that impair actin binding disrupt the ability of purified full‐length Srv2/CAP to catalyze nucleotide exchange on ADF/cofilin‐bound actin monomers and accelerate actin turnover in vitro. The same mutations impair Srv2/CAP function in vivo in regulating actin organization, cell growth, and cell morphogenesis. Thus, normal cell growth and organization depend on the ability of Srv2/CAP to recharge actin monomers, and the WH2 domain plays a central role in this process. Our data also reveal that while most isolated WH2 domains inhibit nucleotide exchange on actin, WH2 domains in the context of intact proteins can help promote nucleotide exchange. © 2010 Wiley‐Liss, Inc.

Reverse logistics and social sustainability
Authors: Sarkis Joseph , Helms Marilyn Michelle , Hervani Aref A. 
Published: January 2010

AbstractThe strategic application of reverse supply chain logistics to improve the reclamation of products at the end of their useful life is gaining increased attention. The environmental implications of reclamation, reuse, and recycling to save landfill space, fuel, and costs are becoming more important for organizations. The social and ethical dimensions of sustainability, particularly as they apply to reverse logistics, are emerging topics. The focus of existing reverse logistics research has been on the economic and environmental aspects of sustainability – social sustainability has yet to be comprehensively examined. This paper focuses on addressing this gap in the literature by linking various sustainable indicators with various reverse logistics practices to develop a profile of reverse logistics for social sustainability. By compiling practical, international examples from practice and research, we have used the structure of social sustainability to highlight reverse logistics for social sustainability. The paper concludes with some topics for future research. Copyright © 2010 John Wiley & Sons, Ltd and ERP Environment.
The closo‐[Sn9Ir(cod)]3– and [Pb9Ir(cod)]3– Zintl Ions: Isostructural IrI Derivatives of the nido‐E94– Anions (E = Sn, Pb)
Authors: Downing Domonique O. , Zavalij Peter , Eichhorn Bryan W. 
Published: January 2010

AbstractThe closo‐[E9Ir(cod)]3– ions where E = Sn (1), Pb (2) (cod = 1,5‐cyclooctadiene) were prepared from precursors [Ir(cod)Cl]2, K4E9, and 2,2,2‐cryptand in ethylenediamine/toluene solvent mixtures. The [K(2,2,2‐crypt)]+ salts were isolated and characterized by NMR spectroscopy and single‐crystal X‐ray diffraction. The clusters are the first known IrI Zintl clusters and are examples of isostructural Sn/Pb homologues. Complexes 1 and 2 have 22‐electron, bicapped square‐antiprismatic structures and pseudo‐C4v point symmetry with the Ir(cod) vertices attached in an η4 fashion. The structural studies and 1H and 13C NMR spectroscopic studies showed significant charge transfer to the COD ligands.
α‐Phosphanyl Amino Acids: Synthesis, Structure and Reactivity of N‐Aryl‐α‐phosphanylglycines
Authors: Lach Joanna , Guo Cun‐Yue , Kindermann Markus K. , Jones Peter G. , Heinicke Joachim 
Published: January 2010

AbstractThe novel N‐aryl‐α‐phosphanylglycines 1a–d have beeneasily prepared by one‐pot three‐component reactions of diphenylphosphane, primary arylamines and glyoxylic acid hydrate in diethyl ether. The reactions proceed via intermediate arylammonium (diphenylphosphanyl)glycolates 2 and stop at this stage in the case of N‐secondary anilines, for example, the stable N‐methylanilinium phosphanylglycolate 3. The conversion of 2 into 1 is an equilibrium, as demonstrated by the reversible hydrolysis of 1b to 2b in [D8]THF containing varying amounts of water. The solid α‐phosphanyl amino acids are stable, but in THF or DMSO solution they suffer from slow decarboxylation, which becomes rapid on heating at about 80 °C, yielding N‐secondary phosphanylmethylanilines 4. Solutions of 1 in the polar protic solvent methanol are stable over long periods, but show rapid proton/deuterium exchange even of the α‐CH proton in deuteriomethanol and thus increased CH acidity compared with normal α‐amino acids. This and the sensitivity to hydrolysis hint at an acetal‐like character and partial protonation even at the phosphorus atom. Oxidation of the N‐aryl derivatives 1b,c by aqueous H2O2 proceeds more rapidly than hydrolysis and provides the first examples of phosphinoylglycines 5. Oxidation by sulfur is rapid even at room temperature in methanol, giving the thiophosphinoylglycines 6. The coordination properties of 1 at the phosphanyl group are characterized by the reaction of 1b with [MVI(CO)5(THF)] (MVI = Cr, Mo, W) and the coordination chemical shifts in the NMR spectra and νCO shifts in the IR spectra of the resulting [(1b)MVI(CO)5] complexes 7b–9b. The structures of the new compounds were elucidated by crystal structure analysis of 1b and 6b and the solution NMR spectroscopic data of all the compounds. Screening for the nickel‐catalysed oligomerization of ethylene showed the formation of active catalysts from 1 and Ni(cod)2.
The neural control of bimanual movements in the elderly: Brain regions exhibiting age‐related increases in activity, frequency‐induced neural modulation, and task‐specific compensatory recruitment

Published: January 2010

AbstractCoordinated hand use is an essential component of many activities of daily living. Although previous studies have demonstrated age‐related behavioral deficits in bimanual tasks, studies that assessed the neural basis underlying such declines in function do not exist. In this fMRI study, 16 old and 16 young healthy adults performed bimanual movements varying in coordination complexity (i.e., in‐phase, antiphase) and movement frequency (i.e., 45, 60, 75, 90% of critical antiphase speed) demands. Difficulty was normalized on an individual subject basis leading to group performances (measured by phase accuracy/stability) that were matched for young and old subjects. Despite lower overall movement frequency, the old group “overactivated” brain areas compared with the young adults. These regions included the supplementary motor area, higher order feedback processing areas, and regions typically ascribed to cognitive functions (e.g., inferior parietal cortex/dorsolateral prefrontal cortex). Further, age‐related increases in activity in the supplementary motor area and left secondary somatosensory cortex showed positive correlations with coordinative ability in the more complex antiphase task, suggesting a compensation mechanism. Lastly, for both old and young subjects, similar modulation of neural activity was seen with increased movement frequency. Overall, these findings demonstrate for the first time that bimanual movements require greater neural resources for old adults in order to match the level of performance seen in younger subjects. Nevertheless, this increase in neural activity does not preclude frequency‐induced neural modulations as a function of increased task demand in the elderly.

Decreased purinergic inhibition of synaptic activity in a mouse model of Niemann‐Pick disease type C
Authors: Zhou Su‐ya , Xu Shu‐jun , Yan Ying‐gang , Yu Hui‐mei , Ling Shu‐cai , Luo Jian‐hong 
Published: January 2010

AbstractNiemann‐Pick disease type C (NPC) is a progressive neurodegenerative disorder characterized by accumulation of free cholesterol in lysosomes, mainly due to a mutation in the NPC1 gene. The pathophysiological basis of the neural disorders in NPC, however, is not well understood. We found that the hippocampal field excitatory postsynaptic potential (fEPSP) was enhanced in NPC1 mutant mice. A1‐receptor antagonist or adenosine degrading enzyme enhanced the fEPSP in both types of mice, but had a much weaker effect in the mutant mice, suggesting less tonic inhibition of synaptic transmission by endogenous adenosine in the mutant. Further evidence showed impaired hippocampal long term potentiation (LTP) in mutant mice. Supplement of A1 agonist N6‐Cyclopentyladenosine (CPA) partially rescued the impaired LTP in mutant mice. Moreover, adenosine release from hippocampal slices was significantly decreased in the mutant. The enhanced excitatory synaptic transmission and the decreased synaptic plasticity due to the decreased adenosine release in NPC brain may partially contribute to the neural disorders of NPC disease, such as seizures, neurodegeneration, and dementia. © 2010 Wiley‐Liss, Inc.
The temporal unraveling of autobiographical memory narratives in patients with temporal lobe epilepsy or excisions
Authors: St‐Laurent M. , Moscovitch M. , Tau M. , McAndrews M.P. 
Published: January 2010

AbstractMedial temporal lobe epilepsy (TLE), a condition known to affect the integrity and function of medial temporal lobe structures such as the hippocampus, has been shown to disrupt memory for real‐life episodes. Here, patients with unilateral TLE, patients who received a unilateral temporal lobe resection to cure TLE, and healthy controls produced free narratives of autobiographical memories (AMs). To assess temporal resolution, narratives were segmented into bits of information, or details, which were classified according to how precisely they could be located within the time course of the AM. Categories included details corresponding to the entire AM, to parts or subevents within the AM, and to actions taking place within seconds to minutes. The number of details per category was tallied and compared between patients and controls. Temporal order was assessed by determining the correct (internally consistent) chronological order of the sequence of events within the narrative. Results indicate that while patients' memory for the parts or subevents of personal episodes was intact, as was their temporal order, their memory for the minute‐by‐minute unraveling of the episode was impaired. We believe this loss of temporally specific details may contribute to the reduced vividness of AM recollection in TLE patients. Our findings provide further evidence that patients with hippocampal damage retrieve skeletal AMs for which the gist of the memory is maintained, but the specific details are lost. © 2010 Wiley‐Liss, Inc.
p14ARF interacts with E2F factors to form p14ARF–E2F/partner‐DNA complexes repressing E2F‐dependent transcription
Authors: Zhang Hai‐Jun , Li Wen‐Juan , Gu Yan‐Yan , Li Shu‐Yan , An Guo‐Shun , Ni Ju‐Hua , Jia Hong‐Ti 
Published: January 2010

AbstractPrimarily, E2F factors such as E2F1, ‐2, and ‐3 stimulate cell‐cycle progression, while ARF tumor suppressor mediates growth suppression. The ARF gene can be induced by oncogenic signal through activating E2F‐dependent transcription. In turn, ARF may target E2F for its degradation via a p53‐dependent mechanism. However, it remains unclear how the cell keeps the balance between the functional opposites of E2F and ARF. In this study, we demonstrate that p14ARF interacts with E2F1–3 factors to directly repress their transcriptional activities through forming p14ARF–E2F/partner‐DNA super complexes, regardless of E2F protein degradation. The inhibition of E2F transcriptional activities by p14ARF in this manner occurs commonly in a variety of cell types, including p53‐deficient and p53‐wild type cells. Thus, E2F‐mediated activation of the ARF gene and ARF‐mediated functional inhibition of E2F compose a feedback loop, by which the two opposites act in concert to regulate cell proliferation and apoptosis, depending on the cellular context and the environment.

Published: January 2010

AbstractThe gas‐phase reaction pathways in preparing pyrolytic carbon with propene pyrolysis have been investigated in detail with a total number of 110 transition states and 50 intermediates. The structure of the species was determined with density functional theory at B3PW91/6‐311G(d,p) level. The transition states and their linked intermediates were confirmed with frequency and the intrinsic reaction coordinates analyses. The elementary reactions were explored in the pathways of both direct and the radical attacking decompositions. The energy barriers and the reaction energies were determined with accurate model chemistry method at G3(MP2) level after an examination of the nondynamic electronic correlations. The heat capacities and entropies were obtained with statistical thermodynamics. The Gibbs free energies at 298.15 K for all the reaction steps were reported. Those at any temperature can be developed with classical thermodynamics by using the fitted (as a function of temperature) heat capacities. It was found that the most favorable paths are mainly in the radical attacking chain reactions. The chain was proposed with 26 reaction steps including two steps of the initialization of the chain to produce H and CH3 radicals. For a typical temperature (1200 K) adopted in the experiments, the highest energy barriers were found in the production of C3 to be 203.4 and 193.7 kJ/mol. The highest energy barriers for the production of C2 and C were found 174.1 and 181.4 kJ/mol, respectively. These results are comparable with the most recent experimental observation of the apparent activation energy 201.9 ± 0.6 or 137 ± 25 kJ/mol. © 2010 Wiley Periodicals, Inc. J Comput Chem, 2010
Canonical Monte Carlo simulation of adsorption of O2 and N2 mixture on single walled carbon nanotube at different temperatures and pressures

Published: January 2010

AbstractAdsorption of pure and mixtures of O2 and N2 on isolated single‐walled carbon nanotube (SWCNT) have been investigated at the subcritical (77 K) and different supercritical (273, 293, and 313K) temperatures for the pressure range between 1 and 31 MPa using (N,V,T) Monte Carlo simulation. Both O2 and N2 gravimetric storage capacity exhibit similar behaviors, gas adsorption is higher on outer surface of tube, compared to the inner surface. Results are consistent with the experimental adsorption measurements. All adsorption isotherms for pure and mixture of O2 and N2 are characterized by type I (Langmuir shape), indicating enhanced solid‐fluid interactions. Comparative studies reveal that, under identical conditions, O2 adsorption is higher than N2 adsorption, due to the adsorbate structure. Excess amount of O2 and N2 adsorption reach to a maximum at each temperature and specified pressure which can be suggested an optimum pressure for O2 and N2 storage. In addition, adsorptions of O2 and N2 mixtures have been investigated in two different compositions: (i) an equimolar gas mixture and (ii) air composition. Also, selectivity of nanotube to adsorption of O2 and N2 gases has been calculated for air composition at ambient condition. © 2010 Wiley Periodicals, Inc. J Comput Chem, 2010
Polymer conformations in internal (polyspherical) coordinates
Authors: Pesonen Janne , Henriksson Krister O. E. 
Published: January 2010

AbstractThe small‐amplitude conformational changes in macromolecules can be described by the changes in bond lengths and bond angles. The descriptors of large scale changes are torsions. We present a recursive algorithm, in which a bond vector is explicitly written in terms of these internal, or polyspherical coordinates, in a local frame defined by two other bond vectors and their cross product. Conformations of linear and branched molecules, as well as molecules containing rings can be described in this way. The orientation of the molecule is described by the orientation of a body frame. It is parametrized by the instantaneous rotation angle, and the two angles that parametrize the orientation of the instantaneous rotation axis. The reason not to use more conventional Euler angles is due to the fact that Euler angles are not well‐defined in gimbal lock (i.e., when a body axis becomes aligned with its space fixed counter part). The position of the molecule is parametrized by its center of mass. Original and calculated positions are compared for several proteins, containing up to about 100,000 atoms. © 2010 Wiley Periodicals, Inc. J Comput Chem, 2010
