Measuring Subtypes of Emotion Regulation: From Broad Behavioural Skills to Idiosyncratic Meaning‐making
Authors: Pascual‐Leone Antonio , Gillespie Nicole M. , Orr Emily S. , Harrington Shawn J. 
Published: February 2015

The current paper introduces the notion of clinically relevant subtypes of emotion regulation behaviours. A new measure of emotion regulation, the Complexity of Emotional Regulation Scale (CERS), was established as psychometrically sound. It was positively correlated with a measure of emotional awareness (r = 0.28, p < 0.001) and negatively correlated with measures of self‐criticism (r = −0.28, p < 0.001) and depression (r = −0.35, p = 0.025), among others. Participants were drawn from two samples: clients from a university counselling centre and a non‐clinical student sample. Comparisons were conducted between non‐clinical and clinical samples to determine the effects of depression and other symptoms of psychopathology on participant's generation of strategies for emotion regulation. Participants in the clinical sample more often identified an intention to soothe but did not follow through as compared with the non‐clinical group, F(1, 198) = 4.662, p < 0.04. Furthermore, individuals in the non‐clinical sample were more likely to engage in specific, meaning‐making strategies when compared with the clinical group, F(1, 198) = 5.875, p < 0.02. Implications from the current studies suggest the possible applicability of the CERS to clinical settings using an interview rather than questionnaire format.

Emotion regulation should be thought of as being on a continuum of complexity, where strategies range from general (‘one size fits all’) action to specific (‘personal and idiosyncratic’) meaning. The best emotion regulation strategy depends on a client's presenting difficulty and level of distress.
Acidic Ionic Liquids as Sustainable Approach of Cellulose and Lignocellulosic Biomass Conversion without Additional Catalysts
Authors: da Costa Lopes André M. , Bogel‐Łukasik Rafał 
Published: February 2015

AbstractThe use of ionic liquids (ILs) for biomass processing has attracted considerable attention recently as it provides distinct features for pre‐treated biomass and fractionated materials in comparison to conventional processes. Process intensification through integration of dissolution, fractionation, hydrolysis and/or conversion in one pot should be accomplished to maximise economic and technological feasibility. The possibility of using alternative ILs capable not only of dissolving and deconstructing selectively biomass but also of catalysing reactions simultaneously are a potential solution of this problem. In this Review a critical overview of the state of the art and perspectives of the hydrolysis and conversion of cellulose and lignocellulosic biomass using acidic ILs using no additional catalyst are provided. The efficiency of the process is mainly considered with regard to the hydrolysis and conversion yields obtained and the selectivity of each reaction. The process conditions can be easily tuned to obtain sugars and/or platform chemicals, such as furans and organic acids. On the other hand, product recovery from the IL and its purity are the main challenges for the acceptance of this technology as a feasible alternative to conventional processes.

AbstractThylakoid membranes (TMs) are uniquely suited for photosynthesis owing to their distinctive structure and composition. Substantial efforts have been directed towards use of isolated photosynthetic reaction centers (PRCs) for solar energy harvesting, however, few studies investigate the communication between whole TMs and electrode surfaces, due to their complex structure. Here we report on a promising approach to generate photosynthesis‐derived bioelectricity upon illumination of TMs wired with an osmium‐redox‐polymer modified graphite electrode, and generate a photocurrent density of 42.4 μA cm−2.
Current Technologies, Economics, and Perspectives for 2,5‐Dimethylfuran Production from Biomass‐Derived Intermediates
Authors: Saha Basudeb , Abu‐Omar Mahdi M. 
Published: February 2015

AbstractSince the U.S. Department of Energy (DOE) published a perspective article that described the potential of the top ten biomass‐derived platform chemicals as petroleum replacements for high‐value commodity and specialty chemicals, researchers around the world have been motivated to develop technologies for the conversion of biomass and biomass‐derived intermediates into chemicals and fuels. Among several biorefinery processes, the conversion of biomass carbohydrates into 2,5‐dimethylfuran (DMF) has received significant attention because of its low oxygen content, high energy content, and high octane value. DMF can further serve as a petroleum‐replacement, biorenewable feedstock for the production of p‐xylene (pX). In this review, we aim specifically to present a concise and up‐to‐date analysis of DMF production technologies with a critical discussion on catalytic systems, mechanistic insight, and process economics, which includes sensitivity analysis, so that more effective catalysts can be designed. Special emphasis has been given to bifunctional catalysts that improve DMF yields and selectivity and the synergistic effect of the bifunctional sites. Process economics for the current processes and the scope for further improvement are discussed. It is anticipated that the chemistry detailed in this review will guide researchers to develop more practical catalytic processes to enable the economic production of bio‐based DMF. Processes for the upgrade of DMF to pX are also described.
Governing Chemistry of Cellulose Hydrolysis in Supercritical Water
Authors: Cantero Danilo A. , Bermejo M. Dolores , Cocero M. José 
Published: February 2015

AbstractAt extremely low reaction times (0.02 s), cellulose was hydrolyzed in supercritical water (T=400 °C and P=25 MPa) to obtain a sugar yield higher than 95 wt %, whereas the 5‐hydroxymethylfurfural (5‐HMF) yield was lower than 0.01 wt %. If the reaction time was increased to 1 s, the main product was glycolaldehyde (60 wt %). Independently of the reaction time, the yield of 5‐HMF was always lower than 0.01 wt %. To evaluate the reaction mechanism of biomass hydrolysis in pressurized water, several parameters (temperature, pressure, reaction time, and reaction medium) were studied for different biomasses (cellulose, glucose, fructose, and wheat bran). It was found that the H+ and OH− ion concentration in the reaction medium as a result of water dissociation is the determining factor in the selectivity. The reaction of glucose isomerization to fructose and the further dehydration to 5‐HMF are highly dependent on the ion concentration. By an increase in the pOH/pH value, these reactions were minimized to allow control of 5‐HMF production. Under these conditions, the retroaldol condensation pathway was enhanced, instead of the isomerization/dehydration pathway.
Microparticle analysis in disorders of hemostasis and thrombosis
Authors: Mooberry Micah J. , Key Nigel S. 
Published: February 2015

AbstractMicroparticles (MPs) are submicron vesicles released from the plasma membrane of eukaryotic cells in response to activation or apoptosis. MPs are known to be involved in numerous biologic processes, including inflammation, the immune response, cancer metastasis, and angiogenesis. Their earliest recognized and most widely accepted role, however, is the ability to promote and support the process of blood coagulation. Consequently, there is ongoing interest in studying MPs in disorders of hemostasis and thrombosis. Both phosphatidylserine (PS) exposure and the presence of tissue factor (TF) in the MP membrane may account for their procoagulant properties, and elevated numbers of MPs in plasma have been reported in numerous prothrombotic conditions. To date, however, there are few data on true causality linking MPs to the genesis of thrombosis. A variety of methodologies have been employed to characterize and quantify MPs, although detection is challenging due to their submicron size. Flow cytometry (FCM) remains the most frequently utilized strategy for MP detection; however, it is associated with significant technological limitations. Additionally, preanalytical and analytical variables can influence the detection of MPs by FCM, rendering data interpretation difficult. Lack of methodologic standardization in MP analysis by FCM confounds the issue further, although efforts are currently underway to address this limitation. Moving forward, it will be important to address these technical challenges as a scientific community if we are to better understand the role that MPs play in disorders of hemostasis and thrombosis. © 2015 International Society for Advancement of Cytometry

AbstractThe recent introduction of mass cytometry, a technique coupling a cell introduction system generating a stream of single cells with mass spectrometry, has greatly increased the number of parameters that can be measured per single cell. As with all new technology there is a need for dissemination of standardization and quality control procedures. Here, we characterize variations in sensitivity observed across the mass range of a mass cytometer, using different lanthanide tags. We observed a five‐fold difference in lanthanide detection over the mass range and demonstrated that each instrument has its own sensitivity pattern. Therefore, the selection of lanthanide combinations is a key step in the establishment of a staining panel for mass cytometry‐based experiments, particularly for multicenter studies. We propose the sensitivity pattern as the basis for panel design, instrument standardization and future implementation of normalization algorithms. © 2015 International Society for Advancement of Cytometry
One‐Step Green Synthesis of Multifunctional Fe3O4/Cu Nanocomposites toward Efficient Reduction of Organic Dyes

Published: February 2015

AbstractNoble‐metal‐derived functional materials have played indispensable roles in the reduction of dye under aqueous conditions; however, their cost and separation are great limitations on their wider practical applications. Therefore, an alternative preparation of comparable materials with low cost and good ease of separation is required. Herein magnetic microspheres (i.e., Fe3O4/Cu) were synthesized through a green single‐step solvothermal method for the first time with ethylene glycol serving as reductant and reaction media. The prepared materials were characterized by means of powder X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy, energy‐dispersive X‐ray spectrometry, a vibrating sample magnetometer, and so forth. Additionally, by employing the reduction of 4‐nitrophenol to 4‐aminophenol as a model reaction, the effects of preparation time and the initial dosage of Cu(NO3)2 on the rate constant of the catalytic reduction reaction were systematically investigated. Moreover, the obtained hybrid nanocatalysts were also applied to reduce and degrade common organic dyes (rhodamine B and methylene blue) in the presence of NaBH4. Quite significantly, it was shown that it could catalytically degrade different organic dyes with excellent catalytic performance and high stability in recycled reactions up to five times. More interestingly, the material can be easily separated from the catalytic system for further use.

Published: February 2015

AbstractHydrophilic coordinating chiral ionic liquids with an amino alcohol substructure were developed and efficiently applied to the asymmetric reduction of ketones. Their careful design and adaptability to the desired reaction conditions allow for these chiral ionic liquids to be used as the sole source of chirality in a ruthenium‐catalyzed transfer hydrogenation reaction of aromatic ketones. When used in this reaction system, these chiral ionic liquids afforded excellent yields and high enantioselectivities.

AbstractWe describe the stereoselective synthesis of highly functionalized 1‐substituted (E)‐1,3‐dienes by reductive β‐elimination of 2‐chloroallyl acetates, derived from the indium‐promoted allylation of aldehydes with 1,3‐dichloropropene and subsequent acetylation. The procedure is mild, straightforward, and simple, and it is generally applicable to a very diverse range of functionalized substrates.

AbstractBackgroundThe aim of this study was to investigate the associations between sickness absence due to back pain or depressive episode with future all‐cause and diagnosis‐specific disability pension, while adjusting for comorbidity and socio‐demographics, for all and stratifying for sex.MethodIn total, 4,823,069 individuals aged 16–64 years, living in Sweden at the end of 2004, not on old‐age or disability pension in 2005 and without ongoing sickness absence at the turn of 2004/2005 formed the study population. Crude and adjusted hazard ratios (HRs) for all‐cause and diagnosis‐specific disability pension (2006–2010) in relation to diagnosis‐specific sickness absence with sickness benefits paid by the Social Insurance Agency were estimated using Cox regression.ResultsThe HR for all‐cause disability pension was 7.52 (7.25–7.52) in individuals with an incident sick‐leave spell due to back pain, compared to individuals without sickness absence in 2005 in the fully adjusted (socio‐demographics and comorbidity) model. The fully adjusted (multivariate) HRs for diagnosis‐specific disability pension were musculoskeletal diagnoses 23.87 (22.75–25.04), mental 2.49 (2.27–2.73) or all other diagnoses, 3.44 (3.17–3.75). In individuals with an incident sick‐leave spell due to a depressive episode in 2005, the multivariate adjusted HR for all‐cause disability pension was 12.87 (12.42–13.35), while the multivariate HRs for disability pension due to musculoskeletal diagnoses were 4.39 (3.89–4.96), for mental diagnoses 25.32 (24.29–26.38) and for all other somatic diagnoses 3.44 (3.09–3.82). Men who were sickness absent due to a depressive episode had a higher HR for disability pension compared to women.ConclusionResults indicate that sickness absence due to a depressive episode or back pain is a strong risk factor for a future disability pension due to mental, musculoskeletal or other somatic diagnoses.

Published: February 2015

AbstractElectrochemical detection of nitrite was achieved via electrodeposition of gold nanoparticles (AuNPs) onto glassy carbon electrodes, followed by 3‐mercaptopropionic acid (MPA) self‐assembly, enabling attachment of an iron(III) monoamino‐phthalocyanine (FeMAPc) catalyst via amide bond formation. The use of scanning electron microscopy, energy dispersive X‐ray spectroscopy and ultraviolet‐visible spectroscopy realised surface characterisation while cyclic voltammetry and electrochemical impedance spectroscopy techniques were applied for electrochemical interrogation. The electrochemical behaviour of nitrite at the bare (GCE), AuNPs/GCE, FeMAPc/GCE and FeMAPc‐MPA/AuNPs/GCE was further scrutinised using differential pulse voltammetry in phosphate buffer solution (0.1 M PBS, pH 5.8). Overall the FeMAPc‐MPA/AuNPs/GCE resulted in sensitivity 14.5 nA/µM, which was double that of AuNPs/GCE, 2.4 times FeMAPc/GCE and 3.5 times the response at a bare GCE, with linear range 1.9 µM–2.04 mM (PBS, pH 5.8) and LOD 0.21 µM. An interference study revealed that the proposed sensor (FeMAPc‐MPA/AuNPs/GCE) exhibited a selective response in the presence of interfering anions and the analytical capability of the sensor was demonstrated via nitrite ion determination in real water samples.
Validating a Central Approximation in Theories of Regular Electrode Electrochemical Arrays of Various Common Geometries
Authors: Sliusarenko Oleksii , Oleinick Alexander , Svir Irina , Amatore Christian 
Published: February 2015

AbstractThirty years ago one of us introduced a central approximation according to which the regular arrays behaviors could be estimated based on those of arrays of cylindrical unit cells with the same relative surface area of their central disks for the insulating section. This work examines and validates this approximation on the basis of 3D‐simulations of Brownian particles motion for inlaid or recessed electroactive disks as well as for protruding cylindrical electrodes. The approximation is perfectly adequate for predicting the behavior of realistic experimental arrays and is valid within a few percent even in extreme situations when adjacent electroactive sections are almost touching.

Abstract

Hexabromocyclododecane (HBCDD) is a flame retardant and a global contaminant, yet the toxicokinetics of HBCDD diastereoisomers remains unknown in wildlife species. The present study examined in captive American kestrels (Falco sparverius) (diastereo) isomer-specific HBCDD uptake, depletion, tissue distribution, and transfer to eggs in a dietary dosing study with an HBCDD technical mixture (HBCDD-TM). Adult tissue and plasma collections were from separate cohorts of unpaired individual males (n = 10) and females (n = 10) exposed for 21 d to 800 ng/g wet weight of HBCDD-TM (in safflower oil and injected into their cockerel [brain] diet), followed by a 25-d depuration period. A separate cohort of 12 males only was used for control adult tissue and plasma collections. For egg collections, separate cohorts of 11 control pairs (n = 22 birds) and 20 HBCDD-exposed pairs (n = 40 birds) were allowed to breed, and their eggs were collected (n = 19 exposed eggs and n = 10 control eggs). The sum (Σ) HBCDD concentrations were near or below detection (&lt;0.01–0.1 ng/g wet wt) in all control samples but quantifiable in all samples from exposed birds (no differences [p &gt; 0.05] between males and females). Arithmetic mean ΣHBCDD concentrations were highest in fat &gt;&gt; eggs &gt; liver &gt; plasma. The mean ΣHBCDD depletion rate in plasma between the uptake and depuration periods was estimated to be 0.22 ng/g/d with a half-life of approximately 15 d. The γ-HBCDD diastereoisomer was &gt;60% of the ΣHBCDD in plasma after the uptake period and similar to the HBCDD-TM (∼80%). After the depuration period, α-HBCDD was &gt;70% of the HBCDD in plasma, fat, liver, and eggs; and this α-HBCDD domination indicated isomer-specific accumulation as a result of selective metabolism, uptake, protein binding, and/or in ovo transport.

Reduced mobility of fomesafen through enhanced adsorption in biochar-amended soil
Authors: Khorram Mahdi Safaei , Wang Yun , Jin Xiangxiang , Fang Hua , Yu Yunlong 
Published: February 2015

Abstract

The residual soil material resulting from biomass thermochemical transformation during carbon separation, known as biochar, has been introduced as a soil amendment because of its numerous environmental benefits, including uses for contaminated land management. Adsorption and leaching of fomesafen in soils amended with 3 different rates of rice hull biochar (0.5%, 1%, and 2% w/w) under laboratory conditions were investigated, and studies were performed following a batch equilibration adsorption–desorption procedure and a column experiment for leaching. Adsorption–desorption data fit with the Freundlich equation well. The adsorption coefficient of fomesafen sharply increased from 0.59 to 0.99 to 8.02 to 22.23 when the amount of biochar amendment in the soil increased from 0% to 2% (w/w). In addition, a strong correlation was found between the amount of adsorbed fomesafen and the rate of amended biochar (r &gt; 0.992, p &lt; 0.01). Furthermore, biochar amendments reduced the desorption percentage of fomesafen in the soils. The outcomes of the leaching experiment also illustrated that the lowest fomesafen concentration in the leachate (21.4%) occurred in the soil amended with 2% (w/w) biochar. Moreover, the adsorption coefficients (Kfads) of the soil were positively correlated with the total amount of adsorbed fomesafen in the corresponding soil columns (r = 0.990, p &lt; 0.01) and negatively correlated with the leachate percentage (r = 0.987, p &lt; 0.05). The results of the present study suggest that biochar amendments in agricultural soils likely alter the fate of herbicides by decreasing their transport through enhanced adsorption.

Effects of benthos, temperature, and dose on the fate of hexabromocyclododecane in experimental coastal ecosystems

Published: February 2015

Abstract

The authors studied the fate of the brominated flame retardant hexabromocyclododecane (HBCDD) added in a particulate suspension to experimental ecosystems assembled from brackish (Baltic Sea) coastal bays. Two experiments examined how benthic macrofauna (over 21 d) and increased temperature (14 d) affected HBCDD concentrations and fractionation of α, β, and γ diastereomers in the water, sediment, and biota. A third experiment run over 3 seasons (231 d), studied the effect of HBCDD dose on the same endpoints. In all treatments of the 3 experiments, HBCDD partitioned mainly to the sediment, and this proportion increased with time. Presence of macrofauna tended to increase the HBCDD concentration in the sediment and decreased its concentration in the water. Increased temperature (+ 5°C) decreased the amount of HBCDD in sediment and water but not in the filter- and deposit-feeding infaunal bivalves (Macoma balthica). The partitioning between water, sediment, and biota was not concentration dependent. In all treatments, sediment became enriched in γ-HBCDD, M. balthica in α-HBCDD, and water in α- and β-HBCDD. Bioaccumulation of HBCDD in M. balthica was high in all experiments (log biota-sediment accumulation factor [BSAF] &gt; 1.25), the α diastereomer contributing the most (log BSAF 2.1–5.2). There is a risk of trophic transfer of HBCDD from benthic to pelagic food webs, as well as secondary poisoning of marine consumers. Environ Toxicol Chem 2015;34:1246–1257. © 2015 SETAC
