Using motivational interviewing to engage adolescents and young adults with diabetes
Authors: Christie Deborah , Channon Sue 
Published: August 2014

AbstractFor young people trying to keep diabetes under control the behaviours can appear simple; e.g. following a healthy diet, regular self‐monitoring and exercise. However, clinicians and parents are often frustrated by the gap between the ‘ideal’ and ‘reality’. Young people have conflicting motivations and pressures; a change in behaviour feels too big, the rewards too distant, the personal or financial costs too high, or maybe it was never their idea to change in the first place. Attention has turned to the potential of motivational interviewing in the paediatric setting, particularly with the adolescent age group. Motivational interviewing is a directive person‐centred therapeutic style that invites individuals to explore ambivalence and find solutions that fit for them if they identify the situation as a problem. Early trials support the use of motivational interviewing in type 1 diabetes in adolescents, either as a stand‐alone treatment or as an adjunct to other treatments where it can be a method of engaging patients in the programmes thus enabling the programmes to be more effective. This paper describes the core principles and key skills of motivational interviewing and offers clinical examples with young people and parents living with diabetes.

Successful Use of Octreotide as a Chemoprotectant for Prevention of PEG‐Asparaginase–Induced Pancreatitis
Authors: Buie Larry W. , Moore Joseph , van Deventer Hank 
Published: August 2014

l‐asparaginase is an aminohydrolase that deprives leukemia cells of l‐asparagine required for protein synthesis. Although studies in patients with acute lymphoblastic leukemia have shown that the addition of l‐asparaginase improved the overall remission rate, life‐threatening acute pancreatitis has occurred in 0.5–4% of patients. We describe the first adult case report, to our knowledge, of the successful use of octreotide as a chemoprotectant for the prevention of recurrent pegylated asparaginase (PEG‐ASP)–induced pancreatitis in a 21‐year‐old man with Philadelphia chromosome–negative acute lymphoblastic leukemia. After recurrent PEG‐ASP administration during induction chemotherapy, he developed necrotizing pancreatitis, confirmed by abdominal computed tomography, and further asparaginase therapy was withheld. Currently, there are no specific treatment recommendations for the management of asparaginase‐induced pancreatitis other than drug discontinuation. After disease relapse, a pediatric PEG‐ASP–containing regimen was initiated, and PEG‐ASP therapy was resumed due to its potential clinical benefit. Octreotide 100 μg subcutaneously 3 times/day, utilized as a chemoprotectant, was found to prevent pancreatitis recurrence. The patient completed therapy and was able to receive a bone marrow transplant without further complications from PEG‐ASP therapy. Based on this patient's experience, we believe it is reasonable to reincorporate PEG‐ASP after an episode of pancreatitis with use of octreotide as a chemoprotectant; however, this conclusion will need to be substantiated in a randomized clinical trial with a larger group of patients.

Published: August 2014

AbstractauthorenWe present a temperature‐ and intensity‐dependent photoluminescence (PL) study of the binary semiconductor on the mm‐scale and a laterally resolved PL measurement with a resolution of nm. The films can show a rather rough surface with needles and flakes of with different orientations as well as very flat and smooth surface morphology. Despite a band gap of eV the films show a splitting of quasi‐Fermi levels (QFL) of meV at room temperature.By means of temperature‐dependent PL we have located several radiative and non‐radiative defect states in the band gap. For a better understanding of this thin film semiconductor a full analysis of the laterally resolved PL measurement including the integrated PL yield, energetic position of the PL maximum, optical band gap, splitting of quasi‐Fermi levels and defect absorption of both sample morphologies is presented to avoid misinterpretation of experimental data.
High‐Density Monolayers of Metal Complexes: Preparation and Catalysis
Authors: Hara Kenji , Sawamura Masaya , Fukuoka Atsushi 
Published: August 2014

AbstractCatalysts are one of the key materials for realizing a sustainable society. However, we may encounter problematic cases where conventional catalyst systems cannot provide effective solutions. We thus believe that the establishment of novel methods of catalyst preparation is currently necessary. Utilization of high‐density monolayers of molecular metal complexes is our strategy, and we expect that this methodology will enable facile and systematic screening of unique and efficient catalysts. This Personal Account describes our challenges to establish such an immature method in catalyst preparation as well as the related background and perspective. Preparation and catalysis by high‐density monolayers of Rh complexes with N‐heterocyclic carbene, structurally compact phosphine and diisocyanide ligands on gold surfaces are presented. The catalytic application of a high‐density Pd–bisoxazoline complex prepared on a single‐crystal silicon surface is also shown. Uniquely high catalyst turnover numbers and high chemoselectivities were observed with these catalyst systems.
8‐Hydroxy‐2′‐deoxyguanosine as a biomarker of oxidative DNA damage induced by perfluorinated compounds in TK6 cells

Published: August 2014

ABSTRACT8‐Hydroxy‐2′‐deoxyguanosine (8‐OHdG) is the most common biomarker of oxidative DNA damage, it is formed by chemical carcinogens and can be measured in any species. Perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA) are suspected genotoxic carcinogens through induction of reactive oxygen species that are responsible for oxidative DNA damage. This study was conducted to investigate the in vitro genotoxicity of PFOA and PFNA in human lymphoblastoid (TK6) cell line. TK6 cells were exposed to PFOA at 0, 125, 250, and 500 ppm and PFNA at 125 and 250 ppm for 2 h. Single cell gel electrophoresis (comet assay) was used to measure DNA damage; at least 50 cells per sample were analyzed using comet Assay Software Project (CASP). 8‐OHdG was measured in DNA of exposed cells using high‐performance liquid chromatography (HPLC)‐mass spectrometry (MS)/MS. Results showed that both PFOA and PFNA induced DNA damage indicated by increased tail length (DNA migration). The level of 8‐OHdG was increased in a dose‐dependent manner in both PFOA and PFNA exposure. We concluded that PFOA and PFNA induced DNA damage and the biomarker of oxidative DNA damage (8‐OHdG) could be measured by HPLC‐MS/MS. In addition, PFNA produced high level of 8‐OHdG at concentrations lower than PFOA, this may indicate that PFNA is more potent genotoxicant for TK6 cells than PFOA. © 2014 Wiley Periodicals, Inc.

Distributed two‐hop proportional fair resource allocation in Long Term Evolution Advanced networks
Authors: Sun Chen , Wang Weidong , Zhang Yinghai , Wang Xiaojun 
Published: August 2014

AbstractIn Long Term Evolution Advanced networks with Type I in‐band half‐duplex decode‐and‐forward relay nodes, proportional fair (PF) resource allocation is aiming at guaranteeing two‐hop match and optimising global proportional fairness. The two‐hop match is defined as equal data rates in the access links and the corresponding backhaul links. The global proportional fairness is between all the user equipments served by the evolved nodes B and the relay nodes. Existing centralised schemes achieve these targets at the cost of enormous channel state information (CSI) exchange. Existing distributed schemes focus on resource partitioning and employ a traditional single‐hop PF scheduling algorithm in access links, with less CSI exchange. The traditional PF scheduling algorithm maximises single‐hop proportional fairness between the data rates in the access links rather than two‐hop proportional fairness between the end‐to‐end data rates in the two hops. In order to reduce CSI exchange and at the same time to maximise the two‐hop proportional fairness, a distributed two‐hop PF resource allocation scheme is proposed. The proposed scheme includes two‐hop PF resource scheduling algorithms and adaptive resource partitioning algorithms, applied in different two‐hop transmission protocols. Simulation results demonstrate the proposed scheme is better than the existing distributed schemes in obtaining better proportional fairness and larger cell‐edge user equipment throughputs.

Published: August 2014

AbstractThree coordination polymers, [Zn(HL)(phen)(H2O)]n (1), [Zn1.5(L)(4, 4′‐bpy)1.5]n·4nH2O (2), and [Zn2(HL)2(bib)2]n·2nH2O (3), were assembled from the asymmetric semi‐rigid V‐shaped tricarboxylate ligand 4‐(2‐carboxy‐phenoxy)‐isophthalic acid (H3L) with 1, 10‐phenanthroline (phen), 4, 4′‐bipyridine(4, 4′‐bpy) and 1, 4‐bis (imidazol‐1‐yl) benzene (bib) as auxiliary ligands. Complex 1 features a one‐dimensional (1D) double‐looped chain, which is further extended into a 2D supramolecular layer via two kinds of hydrogen‐bonding interactions. Complex 2 exhibits a complicated 3D framework, which can be rationalized as a (3, 4,4)‐connected trinodal net with a unique (4·8·10) (4·8·10·123) (82·122·14·16) topology. Complex 3 has a two‐dimensional (2D) (4, 4) layer formed by the {Zn2} dinuclear SUBs and the bib ligands. The structural and topological differences of the three complexes indicate that the N‐containing auxiliary ligands play important roles in the formation of the final framework structures. In addition, complexes 1–3 were characterized by elemental analysis, IR spectroscopy, and X‐ray powder diffraction. The thermal behaviors and luminescent properties of complexes 1–3 were also investigated in detail.

Published: August 2014

AbstractThe chemistry of low valent late transition metal complexes with a terminal nitrido unit still is a growing field and only few reactions have been studied so far. We have tested the reactivity of a pseudo square planar iridium nitrido complex against triphenyl tin hydride, which results in a highly water sensitive stannyl amido complex, which is an unprecedented example of a transition metal complex with a terminal N(H)–SnR3 ligand.
Impact of rainfall gradient on aboveground biomass and soil organic carbon dynamics of forest covers in Gujarat, India

Published: August 2014

AbstractAlterations in precipitation are affecting forest ecosystems’ soil carbon cycling. To understand how shifts in rainfall may alter these carbon pools, above‐ground biomass (AGB), soil organic carbon (SOC), and microbial biomass carbon (MBC) of tropical forest covers were measured across a rainfall gradient (543–1590 mm) in Gujarat (India), a state falling under semi arid to tropical dry–wet conditions. Species diversity, tree density and soil texture were also measured. Field visits and data collection were carried out for 2 years (2009–2011) in 95 plots of 250 × 250 m in the forest covers across four distinct rainfall zones (RFZs). Data analysis showed that differences seen in the values of the measured parameters across the RFZs are statistically significant (P < 0.05). Positive correlations were observed between mean annual precipitation (MAP) and tree density, species diversity, AGB, SOC, and MBC. Across the RFZs, AGB ranged between 0.09 and 168.28 Mg ha−1; SOC values (up to 25 cm soil depth) varied between 2.94 and 147.84 Mg ha−1. Soil texture and MBC showed a significant impact on the dynamics of SOC in all the RFZs. MBC is more influenced by SOC rather than AGB. Both vegetation type and MAP have an important role in the regulation of SOC in tropical soils. Together, these results reveal complex carbon cycle responses are likely to occur in tropical soils under altered rainfall regimes.
How much is it going to cost me? Bidirectional relations between adolescents' moral personality and prosocial behavior
Authors: Padilla‐Walker Laura M. , Fraser Ashley M. 
Published: August 2014

ABSTRACTThe current study examined bidirectional relations between adolescents' moral personality (prosocial values, self‐regulation, and sympathy) and low‐ and high‐cost prosocial behavior toward strangers. Participants included 682 adolescents (M age of child = 14.31, SD = 1.07, 50% female) who participated at two time points, approximately one year apart. Cross‐lag analyses suggested that adolescents' values were associated with both low‐ and high‐cost prosocial behavior one year later, self‐regulation was associated with high‐cost prosocial behavior, and sympathy was associated with low‐cost prosocial behavior. Findings also suggested that low‐cost prosocial behavior was associated with sympathy one year later, and high‐cost prosocial behavior was associated with values. Discussion focuses on reciprocal relations between moral personality and prosocial behavior, and the need to consider a more multidimensional approach to prosocial development during adolescence.

Authors: Robins Jason A. , Fasih Najla , Schweitzer Mark E. 
Published: August 2014

Purpose We present an analysis of various types and strata of complaints received in a geographically isolated tertiary care center over a 2.5-year period. Methods Research ethics board approval was obtained. The institution described is a closed system with formalized procedures for submitting complaints. All complaints submitted between November 2010 and March 2013 were collected retrospectively. The following data were extracted: type of complainant, nature of the complaint, site or modality of concern, dates in question, and the response. The data were analysed in multiple subgroups and compared with patient and study volume data. Results The frequency of complaints equalled 0.01% (100/1,050,000). The largest group of those who submitted complaints were patients (69% [69/100]), followed by referring physicians (16%). Examination scheduling and interpersonal conflicts were equally of greatest frequency of concern (21% [21/100]), followed by issues with study reporting (16%). The average time interval between complaint submission and formal address was 15 days. Conclusions We present a low frequency of complaints, with the majority of these complaints submitted by patients; scheduling and personal interactions were most often involved. Effective communication, both with patients and referring physicians, was identified as a particular focus for improving satisfaction.
Neotectonic evolution of the Brazilian northeastern continental margin based on sedimentary facies and ichnology,

Published: August 2014

AbstractQuaternary post-Barreiras sediments are widespread along Brazil's passive margin. These deposits are well exposed in the onshore Paraíba Basin, which is one of the rift basins formed during the Pangean continental breakup. In this area, the post-Barreiras sediments consist of sandstones with abundant soft-sediment deformation structures related to seismicity contemporaneous with deposition. The trace fossilsThalassinoidesandPsilonichnusare found up to 38 m above modern sea level in sandstones dated between 60.0 (± 1.4) and 15.1 (± 1.8) ka. The integration of ichnological and sedimentary facies suggests nearshore paleoenvironments. Such deposits could not be related to eustatic sea-level rise, as this time coincides with the last glaciation. Hence, an uplift of 0.63 mm/yr, or 1.97 mm/yr if sea level was 80 m lower in the last glaciation, would have been required to ascend the post-Barreiras sediments several meters above the present-day sea level during the last 60 ka. This would suggest that the post-rift stage of the South American eastern passive margin may have experienced tectonic reactivation more intense than generally recognized. Although more complete data are still needed, the information presented herein may play an important role in studies aiming to decipher the Quaternary evolution of this passive margin.
Natural Frequency and Buckling of Orthotropic Nanoplates Resting on Two-Parameter Elastic Foundations with Various Boundary Conditions
Authors: Sobhy M. 
Published: August 2014

AbstractIn this article, the analyses of the natural frequency and buckling of orthotopic nanoplates, such as single-layered graphene sheets, resting on Pasternak's elastic foundations with various boundary conditions are presented. New functions for midplane displacements are suggested to satisfy the different boundary conditions. These functions are examined by comparing their results with the results obtained by using the functions suggested by Reddy (Reddy JN. Mechanics of Composite Materials and Structures: Theory and Analysis. Boca Raton, FL: CRC Press; 1997). Moreover, these functions are very simple comparing with Reddy's functions, leading to ease of calculations. The equations of motion of the nonlocal model are derived using the sinusoidal shear deformation plate theory (SPT) in conjunction with the nonlocal elasticity theory. The present SPT are compared with other plate theories. Explicit solution for buckling loads and vibration are obtained for single-layered graphene sheets with isotropic and orthotropic properties; and under biaxial loads. The formulation and the method of the solution are firstly validated by executing the comparison studies for the isotropic nanoplates with the results being in literature. Then, the influences of nonlocal parameter and the other parameters on the buckling and vibration frequencies are investigated.
Vibrational Responses of Micro/Nanoscale Beams: Size-Dependent Nonlocal Model Analysis and Comparisons
Authors: Li C. , Chen L. , Shen J.P. 
Published: August 2014

AbstractA size-dependent dynamical model is suggested to investigate the vibrational characteristics of an Euler-Bernoulli micro/nanoscale beam. The strain gradient type of nonlocal elasticity is employed and a small intrinsic length scale parameter is considered in the theoretical model. A partial differential equation that governs transverse motion is derived and the corresponding ordinary differential equation and its dispersion relation are determined from the governing equation by the method of separation of variables. The problem is solved for several sets of strain gradient nonlocal boundary conditions by use of the eigenvalue method. These examples show that strain gradient nonlocality affects the natural frequencies of micro/nanoscale beams significantly. The initial axial force is also proved to play an important role in the vibrational behaviors of a micro/nanoscale beam. The critical compression and critical strain are derived and they are compared with some other approaches. The material constant in nonlocal elasticity theory can be determined by comparing the nonlocal theoretical results with molecular dynamic simulation and it is consistent with the estimation in previous work. Some further comments on the mechanisms of size dependence and physical meaning of micro/nanoscale parameter are presented. Comparisons of natural frequencies by nonlocal theory, classical theory, molecular dynamic simulation and surface effects are also constructed and they indicate the validity of the model developed in the present study.
Three-Wave Mutual-Checking Method for Data Processing of SHPB Experiments of Concrete
Authors: Wang T.-T. , Shang B. 
Published: August 2014

AbstractTwo-wave methods and Three-wave method are conventional methods to process the SHPB experiment data. Due to the presence of transient waves in dynamic experiments, both the stress and strain fields within a specimen are seldom absolutely uniform. Different date processing methods lead to different results. In this paper, we have developed a program to compare the results getting from different methods. The difference of the strains corresponding to the ultimate stress can reach 20%. Which one is better? One material shouldn't have different constitutive. In order to solve the problem, we have developed Three-wave mutual-checking method, which is based on the conservation of the momentum of the whole system. This method provides a checking mechanism, so some human error can be avoided when process the same experiment data. By this method, different person can obtain the only credible stress-strain curve based on the same test data.
Effects of Nanoparticle Migration on Water/Alumina Nanofluid Flow Inside a Horizontal Annulus with a Moving Core
Authors: Malvandi A. , Ganji D. D. 
Published: August 2014

AbstractThe present study is a theoretical investigation of the laminar flow and convective heat transfer of water/alumina nanofluid inside a horizontal annulus with a streamwise moving inner cylinder. A modified, two-component, four-equation, nonhomogeneous equilibrium model is employed for the alumina/water nanofluid, which fully accounts for the effect of the nanoparticle volume fraction distribution. To determine the effects of thermal boundary conditions on the migration of the nanoparticles, two cases are considered: constant heat flux at the outer wall with an adiabatic inner wall (Case A) and constant heat flux at the inner wall with an adiabatic outer wall (Case B). The numerical results indicate that the thermal boundary conditions at the pipe walls significantly affect the nanoparticle distribution, particularly in cases where the ratio of Brownian motion to thermophoretic diffusivities is small. Moreover, increasing the velocity of the moving inner cylinder reduces the heat transfer rate for Case A. Conversely, in Case B, the movement of the inner cylinder enhances the heat transfer rate, and anomalous heat transfer enhancement occurs when the thermophoretic force is dominant (in larger nanoparticles).
Viunalikeviruses are environmentally common agents of horizontal gene transfer in pathogens and biocontrol bacteria
Authors: Matilla Miguel A , Fang Xinzhe , Salmond George P C 
Published: August 2014

Abstract
Bacteriophages have been used as natural biocontrol and therapeutic agents, but also as biotechnological tools for bacterial engineering. We showed recently that the transducing bacteriophage ϕMAM1 is a ViI-like phage and a member of the new genus, ‘Viunalikevirus’. Here, we show that four additional ViI-like phages and three new environmentally isolated viunalikeviruses, all infecting plant and human pathogens, are very efficient generalised transducers capable of transducing chromosomal markers at frequencies of up to 10−4 transductants per plaque-forming unit. We also demonstrate the interstrain transduction of plasmids and chromosomal markers, including genes involved in anabolism, genes for virulence and genes encoding secondary metabolites involved in biocontrol. We propose that all viunalikeviruses are likely to perform efficient horizontal gene transfer. Viunalikeviruses therefore represent useful agents for functional genomics and bacterial engineering, and for chemical and synthetic biology studies, but could be viewed as inappropriate choices for phage therapy.
