Authors: Siano Francesco , Straccia Maria C , Paolucci Marina , Fasulo Gabriella , Boscaino Floriana , Volpe Maria G 
Published: June 2015

AbstractBACKGROUNDNut and seed oils are often considered waste products but in recent years they have been receiving growing interest due to their high concentration of hydrophilic and lipophilic bioactive components, which have important pharmacological properties on human health. The aim of this work was to compare the physico‐chemical and biochemical properties of pomegranate (Punicagranatum), sweet cherry (Prunusavium) and pumpkin (Cucurbita maxima) seed oils obtained by solvent extraction.RESULTSHigh amount of linoleic acid was found in the cherry and pumpkin seed oils, while pomegranate seed oil showed relevant content of polyunsaturated fatty acids (PUFAs) and monounsaturated fatty acids (MUFAs) along to eicosapentaenoic acid (EPA) and nervonic acid. Pumpkin seed oil had high concentration of carotenoids, while pomegranate oil was the best absorber in the UV‐A and UV‐B ranges.CONCLUSIONPomegranate, cherry and pumpkin seed oils can be an excellent source of bioactive molecules and antioxidant compounds such as polyphenols, carotenoids and unsaturated fatty acids. These seed oils can be included both as preservatives and functional ingredients in the food, pharmaceutical and cosmetic fields and can contribute to disease prevention and health promotion. Moreover, high absorbance of UV light indicates a potential use of these oils as filters from radiations in the food, pharmaceutical, and cosmetic fields. © 2015 Society of Chemical Industry
Impact of electron beam irradiation on quality of sea buckthorn (Hippophae rhamnoides L.) oil
Authors: Nemţanu Monica R , Braşoveanu Mirela 
Published: June 2015

AbstractBACKGROUNDSea buckthorn oil is a valuable product that can be incorporated into daily foodstuffs, cosmetics or pharmaceuticals. The effect of accelerated electron irradiation up to 8 kGy on quality characteristics of sea buckthorn oil was investigated in this study.RESULTSIrradiation had no significant influence on phenolic content. Conversely, carotenoid content, antioxidant activity, and oxidative status suffered alterations as the irradiation dose increased. Although no colour changes were visible for oil irradiated up to 3 kGy, the total colour difference indicated clearly changes that involved a two‐step pattern associated with slow degradation of oil colour up to 3 kGy, followed by a fast degradation up to 8 kGy. Some changes of the oil spectral features related to the frequency and intensity of some bands have been found after irradiation, indicating an alteration of the structural integrity induced by irradiation.CONCLUSIONThe present investigation may be a useful starting point for irradiation processing of food or non‐food matrices containing sea buckthorn oil. Thus, sea buckthorn oil safety can be ensured with minimal undesirable changes in its quality by applying irradiation doses up to 3 kGy, which allow control of the microbial contamination depending on microorganism type and initial microbial load. © 2015 Society of Chemical Industry
Aqueous extract of tomato seeds attenuates rotenone‐induced oxidative stress and neurotoxicity in Drosophila melanogaster
Authors: Krishna Gokul , Muralidhara  
Published: June 2015

AbstractBACKGROUNDTomato seeds, a major by‐product from the food processing industry, constitute a rich source of bioactives and a large population consumes tomato (either in raw or cooked form). In the present study, initially we assessed the antioxidant activity of aqueous extract of tomato seeds (TSE) in selected chemical systems and further explored the neuroprotective effects of TSE utilising the rotenone (ROT) model of neurotoxicity in Drosophila.RESULTSAdult male flies (Oregon K) were fed TSE‐enriched medium (0.1–0.2%) with or without ROT (500 µmol L−1) for 7 days. The propensity of TSE to protect flies against ROT‐induced lethality, locomotor phenotype, oxidative stress and neurotoxicity was investigated. TSE offered marked protection against ROT‐induced mortality, while survivors exhibited improved locomotor phenotype. TSE significantly attenuated ROT‐induced oxidative stress, mitochondrial dysfunctions, protein carbonyls content, restored the cholinergic function and dopamine levels.CONCLUSIONWe hypothesise that the efficacy of tomato seed extract to attenuate ROT‐mediated neurotoxicity may be largely related to the combined antioxidant activity of bioactives resulting in abrogation of oxidative stress and mitochondrial dysfunction. More importantly, our approach provides an experimental paradigm to rapidly assess the potential neuroprotective effects of common dietary components employing Drosophila, since it corroborates previous evidence in a mouse model. © 2015 Society of Chemical Industry
Effects of technological processes on enniatin levels in pasta
Authors: Serrano Ana B , Font Guillermina , Mañes Jordi , Ferrer Emilia 
Published: June 2015

AbstractBACKGROUNDPotential human health risks posed by enniatins (ENs) require their control primarily from cereal products, creating a demand for harvesting, food processing and storage techniques capable to prevent, reduce and/or eliminate the contamination. In this study, different methodologies to pasta processing simulating traditional and industrial processes were developed in order to know the fate of the mycotoxin ENs. The levels of ENs were studied at different steps of pasta processing. The effect of the temperature during processing was evaluated in two types of pasta (white and whole‐grain pasta). Mycotoxin analysis was performed by LC‐MS/MS.RESULTSHigh reductions (up to 50% and 80%) were achieved during drying pasta at 45–55°C and 70–90°C, respectively. The treatments at low temperature (25°C) did not change EN levels. The effect of pasta composition did not cause a significant effect on the stability of ENs. The effect of the temperature allowed a marked mycotoxin reduction during pasta processing. Generally, ENA1 and ENB showed higher thermal stability than did ENA and ENB1.CONCLUSIONSThe findings from the present study suggested that pasta processing at medium–high temperatures is a potential tool to remove an important fraction of ENs from the initial durum wheat semolina. © 2015 Society of Chemical Industry
Preparation and Characterization of Fully Furan‐Based Renewable Thermosetting Epoxy‐Amine Systems
Authors: Hu Fengshuo , Yadav Santosh Kumar , La Scala John J. , Sadler Joshua M. , Palmese Giuseppe R. 
Published: June 2015

Fully furan‐based epoxy/amine thermosetting materials are prepared and investigated using a furanyl epoxy monomer, 2,5‐bis[(2‐oxiranylmethoxy)methyl]‐furan (BOF), and two furanyl amine hardeners, 5,5′‐methylenedifurfurylamine (DFDA) and 5,5′‐ethylidenedifurfirylamine (CH3‐DFDA). These furan‐based thermosets have shown promising glass transition temperatures (62 and 69 °C, respectively, using tan delta) and room temperature storage moduli (≈3.5 GPa). The BOF/CH3‐DFDA sample is exhibited higher Tg than the BOF/DFDA system due to the presence of an additional methyl group in CH3‐DFDA. Used as curing agents for DGEBA, DFDA and CH3‐DFDA have shown excellent performance with resulting Tgs well above 120 °C. Onset degradation temperature of the fully furan‐based samples is observed around 270 °C with high char yields (≈40 wt%) at 750 °C in argon. Based on their thermal and mechanical properties, the renewable fully furan‐based thermosets are found suitable for coating, adhesive, and composite applications, and are therefore potential replacements for incumbent systems.image
Experiences in Close Relationships – Psychometric properties among patients with personality disorders
Authors: Pedersen Geir , Eikenæs Ingeborg , Urnes Øyvind , Skulberg Guro Mikaelsen , Wilberg Theresa 
Published: June 2015

ABSTRACTPatients with personality disorders represent maladaptive attachment strategies, influencing the quality of their interpersonal relationships. Within these patient populations, it is important to have a measure, easily applied, to assess such strategies. A widely used instrument is Experiences in Close Relationships (ECR), assessing two constructs called avoidance and anxiety. Lately, two short forms of ECR have been proposed, called ECR‐S and ECR‐N12. The aim of this study is to investigate the psychometric properties of the Norwegian @version of ECR and its two short forms in a sample of patients with mainly personality disorders. An internal consistency and confirmatory factor analysis of ECR, ECR‐S and ECR‐N12 from 495 patients was conducted, as well as an exploratory factor analysis of ECR. The internal consistency of ECR was found questionable. Confirmatory factor analysis revealed a poor model fit based on ECR and ECR‐S. The ECR‐N12 revealed a mediocre fit, indicating a potential for improvement. Exploratory factor analysis indicated two different aspects of avoidance and three aspects of anxiety. This five‐factor solution was called ECR‐FF. Inferences from scores based on ECR should be derived with care. A revision of ECR and ECR‐N12 is warranted, and further studies are needed to investigate the validity of ECR‐FF. Copyright © 2015 John Wiley & Sons, Ltd.
Residue‐level global and local ensemble‐ensemble comparisons of protein domains
Authors: Clark Sarah A. , Tronrud Dale E. , Andrew Karplus P. 
Published: June 2015

AbstractMany methods of protein structure generation such as NMR‐based solution structure determination and template‐based modeling do not produce a single model, but an ensemble of models consistent with the available information. Current strategies for comparing ensembles lose information because they use only a single representative structure. Here, we describe the ENSEMBLATOR and its novel strategy to directly compare two ensembles containing the same atoms to identify significant global and local backbone differences between them on per‐atom and per‐residue levels, respectively. The ENSEMBLATOR has four components: eePREP (ee for ensemble‐ensemble), which selects atoms common to all models; eeCORE, which identifies atoms belonging to a cutoff‐distance dependent common core; eeGLOBAL, which globally superimposes all models using the defined core atoms and calculates for each atom the two intraensemble variations, the interensemble variation, and the closest approach of members of the two ensembles; and eeLOCAL, which performs a local overlay of each dipeptide and, using a novel measure of local backbone similarity, reports the same four variations as eeGLOBAL. The combination of eeGLOBAL and eeLOCAL analyses identifies the most significant differences between ensembles. We illustrate the ENSEMBLATOR's capabilities by showing how using it to analyze NMR ensembles and to compare NMR ensembles with crystal structures provides novel insights compared to published studies. One of these studies leads us to suggest that a “consistency check” of NMR‐derived ensembles may be a useful analysis step for NMR‐based structure determinations in general. The ENSEMBLATOR 1.0 is available as a first generation tool to carry out ensemble‐ensemble comparisons.
Conformational transition paths harbor structures useful for aiding drug discovery and understanding enzymatic mechanisms in protein kinases
Authors: Wong Chung F. 
Published: June 2015

AbstractThis short article examines the usefulness of fast simulations of conformational transition paths in elucidating enzymatic mechanisms and guiding drug discovery for protein kinases. It applies the transition path method in the MOIL software package to simulate the paths of conformational transitions between six pairs of structures from the Protein Data Bank. The structures along the transition paths were found to resemble experimental structures that mimic transient structures believed to form during enzymatic catalysis or conformational transitions, or structures that have drug candidates bound. These findings suggest that such simulations could provide quick initial insights into the enzymatic mechanisms or pathways of conformational transitions of proteins kinases, or could provide structures useful for aiding structure‐based drug design.
Insecticide resistance in pollen beetles over 7 years – a landscape approach
Authors: Riggi Laura GA , Gagic Vesna , Bommarco Riccardo , Ekbom Barbara 
Published: June 2015

AbstractBACKGROUNDIn spite of considerable interest in the impact of pesticides on pest populations, few attempts have been made to link resistance patterns of insect pests to land‐use features across spatial and temporal scales. We hypothesise that pollen beetle pesticide resistance increases in areas with a high proportion of oilseed rape and with an even mixture of winter and spring oilseed rape owing to high pesticide selection pressure in such areas.RESULTSHere, we investigated 7 years of lambda‐cyhalothrin (Karate®) resistance in field‐collected pollen beetle adults from a total of 180 sampling points across ten regions in Sweden. We found a positive effect on pollen beetle pesticide resistance of proportion of oilseed rape and even spring–winter oilseed rape mixture. However, this was true only for the regional spatial scale. Significant land‐use effects in the long‐term models, with oilseed rape data averaged over a longer (4 years) period of time, suggested an effect of regional landscape history on current pest resistance.CONCLUSIONFor successful control of pollen beetle pesticide resistance, we suggest a long‐term regional strategy for oilseed rape management. This land‐use approach provides a framework for further investigations that integrate resistance management into landscape research. © 2015 Society of Chemical Industry
Geo‐cultural Origin and Economic Incorporation of High‐skilled Immigrants in Israel
Authors: Bodankin Moran , Semyonov Moshe 
Published: June 2015

AbstractThe present study focuses on differential modes of economic incorporation and economic success of highly skilled immigrants in Israel. Data were obtained from the 2009–2011 Labor Force and Income Surveys. The analysis pertains to recent immigrants aged 25–64 years who attained academic education prior to migration. Three major geo‐cultural groups of immigrants are compared with Israeli‐born. The groups are as follows: Europe and the Americas, the Former Soviet Union, and Asia and Africa. The multivariate analysis (conducted separately for men and women) reveals significant differences across geo‐cultural groups in labour‐market performance (i.e. economic participation) and in economic outcomes (i.e. attainment of professional occupation, occupational status, and earnings). An ethnic hierarch is observed with Israeli‐born at the top, followed by immigrants from Europe and the Americas; the groups of immigrants from the Former Soviet Union and from Asia or Africa are placed at the bottom of the hierarchy. Although all high‐skilled immigrants are disadvantaged when compared with Israeli‐born, all tend to improve their labour‐market status with the passage of time in the country. However, only immigrants from Europe and the Americas are able to reach economic assimilation with high‐skilled Israeli‐born. Asian–African immigrants and immigrants from the Former Soviet Union are less successful in converting skills into economic success; they remain economically disadvantaged even after 20 years of residence. The impact of geo‐cultural origin on differential ability of immigrants to transmit credentials from one country to another is discussed. Copyright © 2015 John Wiley & Sons, Ltd.
Migration and the Local Transformation of Overseas Development Aid: an Analysis of Migrants' Access to ODA Funds in Catalonia
Authors: Østergaard‐Nielsen Eva , Acebillo‐Baqué Míriam 
Published: June 2015

AbstractThis paper explores the linkages between migrant transnationality, locality, and the transformation of local government practices within the field of overseas development assistance (ODA). A growing literature critically analyses how migrants as development agents are embedded in, as well as challenge, local and transnational power hierarchies. This research field is not only centred on the dynamics in the countries of migrant origin but also includes the interaction between the social and institutional contexts in the receiving country and the transnational development practices of migrants. We explore these wider issues through an analysis of the overall trends in migrant access to ODA among Catalan local governments, which have dedicated a (small) part of their annual budget to ODA activities since the 1980s. We set up an original database with information from four consecutive comprehensive surveys of ODA practices of Catalan local governments between 1999 and 2008, each cohort representing more than 90% of the total Catalan population. Subsequently, we show that variation in migrant access to ODA funds across different local governments and migrant nationalities is related to both the size and diversity of municipalities and a range of institutional/political variables. These include the overall ODA spending of the local government, which party is in power, and the extent to which local governments pool their ODA resources within a regional development association for municipalities. In this way, the analysis contributes to our understanding of the potential of migration and migrant transnational practices to transform local institutional practices.

Family Life Course and the Timing of Women's Retirement – a Sequence Analysis Approach
Authors: Svensson Ingrid , Lundholm Emma , De Luna Xavier , Malmberg Gunnar 
Published: June 2015

AbstractBased on longitudinal data from national Swedish registers, family life course dynamics for all women born in 1935 in Sweden are explored for the period 1990–2006. Focusing primarily on the existence and geographical proximity to parents, children, and grandchildren, assuming that the family life courses affect the life situation as well as strategic decisions, this longitudinal study uses a holistic approach, analysing how different types of family life courses are associated with socio‐economic conditions as well as with the timing of retirement. The primary task was not to identify the causal determinants of work life exit but rather to unfold how retirement transition is entwined into the different types of family life courses, whereby retirement and family ageing are different sides of a multifaceted transition period. By using sequence analysis, the family life courses were structured into sequences and durations of states and different family life course categories were identified. The sequence analyses reveal a complex relation between retirement decisions and having family members around. Early retirement was associated with a category with few relatives but also with a category with two younger generations present, while we found no strong association with early retirement for categories in which the old generation was around for a longer period. Late retirement was associated with belonging to categories characterised by late family formation and having children at home. These differences in retirement behaviour were also significant when controlling for education level, marital status, and type of region in a Cox regression. © 2015 The Authors.

Modernisation, Migration, and Mobilisation: Relinking Internal and International Migrations in the ‘Migration and Development Nexus’
Authors: Hickey Maureen 
Published: June 2015

AbstractThere is growing enthusiasm in academic and policy circles for the positive role that international migrants can play in the development of their home countries and communities. Supranational development organisations, national governments, and other institutions have scrambled to assess the linkages between ‘migration and development’ and to implement new policies and programs to more effectively ‘capture’ transnational remittances in order promote greater development outcomes. This international ‘migration and development’ (MAD) paradigm nevertheless draws heavily on older development models, grounded in modernisation theory, which promoted rapid internal rural‐to‐urban migration. Yet, these connections are rarely acknowledged or analysed within official policy discourses; rather, this MAD nexus is regularly depicted as a new paradigm, one that exists without historical or ideological context. This paper traces out the conceptual connections between past and contemporary linkages of MAD theory. I argue that relinking internal and international migrations literature in development reveals the ways in which modernisation theories that rest on problematic contrasts between modernity/tradition and development/backwardness are unconsciously replicated within current policy discourses. I argue that a return to a close interrogation of the concept of development – as defined by migrant actors themselves – has the potential to both bridge the divide within migration studies and to productively critique migration and development policy discourses in ways that do not elide their historical emergence and political effects.

Orbital effect on the in‐plane critical field in free‐standing superconducting nanofilms
Authors: Wójcik P. , Zegrodnik M. 
Published: June 2015

AbstractThe superconductor to normal metal phase transition induced by the in‐plane magnetic field is studied in free‐standing Pb(111) nanofilms. In the considered structures, the energy quantization induced by the confinement leads to the thickness‐dependent oscillations of the critical field (the so‐called “shape resonances”). In this paper, we examine the influence of the orbital effect on the in‐plane critical magnetic field in nanofilms. We demonstrate that the orbital term suppresses the critical field and reduces the amplitude of the thickness‐dependent critical field oscillations. Moreover, due to the orbital effect, the slope at becomes finite and decreases with increasing film thickness in agreement with recent experiments. The temperature at which the superconductor to normal metal phase transition becomes of the first order is also analyzed.
Universally composable issuer‐free adaptive oblivious transfer with access policy
Authors: Guleria Vandana , Dutta Ratna 
Published: June 2015

AbstractIn today's Internet world, security, privacy and efficiency are three prime concerns in designing any cryptographic protocol. Adaptive oblivious transfer with access policy (AOT‐AP) is widely used in oblivious search of privacy preserving databases in which each message is associated with an access policy and only authorized receivers can access the databases. All the existing AOT‐AP protocols assume a trusted third party called issuer apart from a sender and multiple receivers and are secure under the restriction that the issuer never colludes with a collection of receivers. We propose the first issuer‐freeAOT‐AP in universal composable (UC) framework. Our issuer‐free AOT‐AP is UC secure under standard assumptions assuming malicious adversary in static corruption model. More interestingly, our scheme exhibits significant improvements over the existing schemes. Copyright © 2015 John Wiley & Sons, Ltd.
