Published: October 2016

AbstractThe luminescent MOF [(CH3)2NH2]2[(Zn2O)L]⋅5 DMF (NENU‐519, NENU=Northeast Normal University) with a zeolite BCT topology was successfully synthesized. It is a rare example of a two‐fold interpenetrated framework with a zeolite topology. NENU‐519 demonstrates the ability to selectively adsorb cationic dyes. Furthermore we developed Rh6@NENU‐519 (Rh6=Rhodamine 6G) as a dual‐emitting sensor for probing different volatile organic molecules (VOMs) due to an energy transfer between L and the dye. The composite can be used to distinguish the isomers of o‐, m‐, and p‐xylene and ethylbenzene using the emission‐peak‐height ratios of L to the dye as detectable signals, in which the readout signals are involved in the interactions between the dye@MOF composite and the guest analytes. Moreover, Rh6@NENU‐519 can serve as a luminescent switch for the detection of different aromatic compounds, like benzene, benzene substituted with different groups, and pyridine. In other words, the Rh6@NENU‐519 composite can be used as molecular decoder of the structural information of different VOMs into recognizable luminescent signals. Hopefully this work will open a new corridor to develop luminescent guest@MOF composites as sensors for practical applications.
Cerebral Cortex Electroporation to Study Projection Neuron Migration
Authors: Pacary Emilie , Guillemot François 
Published: October 2016

AbstractBrain electroporation is a rapid and powerful approach to study neuronal development. In particular, this technique has become a method of choice for studying the process of radial migration of projection neurons in the embryonic cerebral cortex. This method has considerably helped to describe in detail the different steps of radial migration and to characterize the molecular mechanisms controlling this process. Delineating the complexities of neuronal migration is critical to our understanding not only of normal cerebral cortex formation but also of neurodevelopmental disorders resulting from neuronal migration defects. Here, we describe in detail the protocols to perform in utero or ex vivo electroporation of progenitor cells in the ventricular zone of the cerebral cortex with the aim of studying the process of radial migration of projection neurons during embryonic development. © 2016 by John Wiley & Sons, Inc.
Trajectory control of manipulator fed by power packets
Authors: Mochiyama Shiu , Takahashi Ryo , Hikihara Takashi 
Published: October 2016

SummaryThe conventional power supply is based on a continuous flow of electricity. Electrically driven independent systems face the limitations of flexibility and efficiency of power management in a network consisting of power sources, converters, and loads. The power packet dispatching system, where electricity is transferred in a discretized form with information, is expected to remove the limitations. The system realizes a dynamic arrangement of power‐line connection between power sources and loads. In this paper, we focus on its application to a manipulator. This is an example of electro‐mechanical actuation in independent systems. We verify the trajectory control of the manipulator fed by power packets numerically and experimentally. The results indicate that power packets as a discretized transfer of electricity can be applied to the electro‐mechanical actuation. Copyright © 2016 John Wiley & Sons, Ltd.

ABSTRACTObjectiveCompulsive exercise is a prominent feature for the majority of patients with Anorexia Nervosa (AN), but there is a dearth of research evaluating assessment instruments. This study assessed the concurrent validity of the exercise items of the Eating Disorder Examination (EDE) and Eating Disorder Examination‐Questionnaire (EDE‐Q), with the Compulsive Exercise Test (CET) and other self‐report exercise measures in patients with AN. We also aimed to perform validation of the CET in an adult clinical sample.MethodsThe sample consisted of 78 adults with AN, recruited for the randomized controlled trial “Taking a LEAP forward in the treatment of anorexia nervosa.” At baseline, participants completed the EDE, EDE‐Q, CET, Reasons for Exercise Inventory (REI), Commitment to Exercise Scale (CES) and Exercise Beliefs Questionnaire (EBQ). Correlational and regression analyses were performed.ResultsEDE exercise days and exercise time per day were positively correlated with each other and with all CET subscales (except Lack of exercise enjoyment), CES mean, EBQ total and REI total. Exercise time per day was associated with a higher EDE global score. The CET demonstrated good concurrent validity with the CES, the REI and the EBQ. Of the self‐reports, the CET explained the greatest variance in eating disorder psychopathology and demonstrated good to excellent reliability in this sample.DiscussionThe EDE and EDE‐Q demonstrated good concurrent validity with the CET. Further research is required to evaluate the CET's factor structure in a large clinical sample. However, the CET has demonstrated strong clinical utility in adult patients with AN. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:533–541)
Grazers structure the bacterial and algal diversity of aquatic metacommunities
Authors: Birtel Julia , Matthews Blake 
Published: October 2016

AbstractConsumers can have strong effects on the biotic and abiotic dynamics of spatially‐structured ecosystems. In metacommunities, dispersing consumers can alter local assembly dynamics either directly through trophic interactions or indirectly by modifying local environmental conditions. In aquatic systems, very little is known about how key grazers, such as Daphnia, structure the microbial diversity of metacommunities and influence bacterial‐mediated ecosystem functions. In an outdoor mesocosm experiment with replicate metacommunities (two 300 L mesocosms), we tested how the presence and absence of Daphnia and the initial density of the microbial community (manipulated via dilution) influenced the diversity and community structure of algae and bacteria, and several ecosystem properties (e.g., pH, dissolved substances) and functions (e.g., enzyme activity, respiration). We found that Daphnia strongly affected the local and regional diversity of both phytoplankton and bacteria, the taxonomic composition of bacterial communities, the biomass of algae, and ecosystem metabolism (i.e., respiration). Diluting the microbial inoculum (0.2–5 μm size fraction) to the metacommunities increased local phytoplankton diversity, decreased bacteria beta‐diversity, and changed the relative abundance of bacterial classes. Changes in the rank abundance of different bacterial groups exhibited phylogenetic signal, implying that closely related bacteria species might share similar responses to the presence of Daphnia.
Simplified procedure for the estimation of local inelastic deformation demands for seismic performance assessment of buildings
Authors: Araújo Miguel , Castro José Miguel 
Published: October 2016

SummaryThe implementation of performance‐based design and assessment procedures in seismic codes leads to the need for an accurate estimation of local component demands. According to Part 3 of Eurocode 8 safety checks should be always conducted in terms of plastic rotations, even when linear elastic methods of analysis are used. This paper demonstrates that linear analysis fails to predict inelastic deformation demands at the member level. Therefore, a simplified procedure that allows for the estimation of beam inelastic deformation demands using linear elastic methods of analysis in a simple and conservative way is presented herein. A number of moment‐resisting steel frames designed according to different criteria and exhibiting different column‐to‐beam strength ratios were analysed and used for the derivation of the proposed procedure. A comparative study between alternative methods of quantifying inelastic deformation demands using linear analysis is also carried out. The results obtained allow concluding about the efficiency and conservativeness of the proposed procedure which makes it attractive to be employed in engineering practice.

Published: October 2016

AbstractBackgroundSensitive and reliable new biomarkers are needed in head and neck cancer to predict the outcome and for therapy that is more effective. Copy number alterations are frequent and play a critical role in cancer.MethodsCopy number alterations of 24 tumor suppressor genes in head and neck cancer were analyzed simultaneously in matched tumor and normal samples from 93 patients using multiplex ligation‐dependent probe amplification (MLPA).ResultsChromosomes 3p and 9p displayed the most common alterations. The gene displaying most frequent losses was the mutL homolog 1 (MLH1) gene, followed by the cyclin‐dependent kinase inhibitor 2A (CDKN2A) and CDKN2B genes. A significant correlation was observed between the CDKN2A and CDKN2B genes. The tissue inhibitor of metalloproteinase (TIMP)3 gene alterations were observed in 8 tumors.ConclusionOur data confirm previous observations and suggest that losses of the MLH1 and CDKN2 genes and alterations of the TIMP3 gene play an important role in head and neck carcinogenesis. © 2016 Wiley Periodicals, Inc.

Published: October 2016

ABSTRACTBackgroundWeight loss and depressive symptoms are critical head and neck cancer outcomes, yet their relation over the illness course is unclear.MethodsAssociations between self‐reported depressive symptoms and objective weight loss across the year after head and neck cancer diagnosis were examined using growth curve modeling techniques (n = 564).ResultsA reciprocal covariation pattern emerged–changes in depressive symptoms over time were associated with same‐month changes in weight loss (t [1148] = 2.05; p = .041), and changes in weight loss were associated with same‐month changes in depressive symptoms (t [556] = 2.43; p = .015). To the extent that depressive symptoms increased, patients lost incrementally more weight than was lost due to the passage of time and vice versa. Results also suggested that pain and eating‐related quality of life might explain the reciprocal association between depressive symptoms and weight loss.ConclusionIn head and neck cancer, a transactional interplay between depressive symptoms and weight loss unfolds over time. © 2016 Wiley Periodicals, Inc.

AbstractBACKGROUNDFactorial determination of the sodium (Na) requirement of heat‐stressed lactating cows is hindered by accurate estimates of the Na losses through sweat. Direct studies, therefore, may be needed requiring information on the time course of healthy animals to become Na depleted and the subsequent rate of repletion. The rate of Na depletion and subsequent rate of Na repletion with two levels of dietary Na to lactating dairy cows housed under tropical conditions were investigated using the salivary Na/K.RESULTSThe 12 lactating cows (salivary Na/K ratio 14.6) rapidly developed clinical signs of Na deficiency, including pica, polyuria and polydipsia, reduced body weight and reduced milk yield when fed a low‐Na ration (0.33 g kg−1 dry matter (DM)) for 3 weeks. Deficiency symptoms were associated with a rapid decrease in salivary Na/K ratio to <4.3 from 7 to 21 days. Subsequent repletion of the cows with NaCl to a ration concentration of 1.1 or 1.6 g Na kg−1 DM for 5 weeks did not restore salivary Na/K ratio to values of >6.CONCLUSIONA daily Na intake of heat‐stressed lactating cows to a ration intake of 1.6 g Na kg−1 DM was insufficient to restore Na deficiency. One week was sufficient to deplete heat‐stressed lactating cows of Na, allowing for rapid dose–response studies utilizing the salivary Na/K ratio as a parameter for Na status of cows under tropical conditions. © 2016 Society of Chemical Industry

PurposeIt is well known that pathological changes in tissue alter its mechanical properties. This holds also true for brain tissue. In case of the brain, however, obtaining information about these properties is hard due to the surrounding cranial bone. In this paper a novel technique to create an imaging contrast based on the aforementioned properties is presented.MethodsThe method is based on an excitation of the brain induced by a short fall. The response of the brain tissue is measured using a motion sensitive MRI sequence.ResultsThe new method is tested by measurements on phantom material as well as on healthy volunteers. In a proof of principle experiment the capability of the approach to identify local alterations in the mechanical properties is shown by means of measurements on meningioma patients.ConclusionThe presented results show the feasibility of the novel method. Even in this early state of the proposed method, comparisons of measurements on meningioma patients with intraoperative palpation suggest that meningioma tissue responds differently to the excitation depending on their mechanical properties.

Authors: Espe Emil K. S. , Skårdal Kristine , Aronsen Jan Magnus , Zhang Lili , Sjaastad Ivar 
Published: October 2016

PurposeTo develop a semiautomatic method for rapid segmentation of myocardial tissue phase mapping (TPM) data.MethodsManual segmentation of the myocardium was performed at end‐diastole and end‐systole. The points in both user‐defined masks were then automatically tracked over the entire cardiac cycle using temporal integration of the velocity field. Paths that failed to visit both masks at the expected times were excluded, after which masks for all time points were generated automatically from the accepted paths. Midventricular and basal phase contrast TPM slices from 12 rats were segmented using the proposed method and fully manual segmentation. The results were compared using Dice's metric and Bland–Altman analysis, and interobserver variability was assessed.ResultsThe semiautomatic method reduced the average user input time from 21 min to 1 min per slice. The Dice metrics between the methods were 0.88 ± 0.03 (midventricular) and 0.83 ± 0.06 (basal), and Bland–Altman limits of agreement of peak systolic and diastolic regional velocities were: midventricular: 0.05 ± 0.65 cm/s, −0.02 ± 0.42 cm/s, and −0.03 ± 0.40 cm/s (radial, tangential, longitudinal); basal: −0.04 ± 0.73 cm/s, 0.03 ± 0.60 cm/s, and −0.04 ± 0.48 cm/s (radial, tangential, longitudinal). Interobserver variability following semiautomatic segmentation was lower than for manual segmentation.ConclusionThe proposed method reduced the segmentation time substantially and exhibited well‐preserved data quality and excellent interobserver limits of agreement.

The CuNi binary alloy can be significant as a catalyst for nitrogen‐doped (N‐doped) graphene growth considering controllable solubility of both carbon and nitrogen atoms. Here, we report for the first time the possibility of synthesizing substitutional N‐doped bilayer graphene on the binary alloy catalyst. Raman spectroscopy, atomic force microscopy and transmission electron microscopy analysis confirm the growth of bilayer and few‐layer graphene domains. X‐ray photoelectron spectroscopy analysis shows the presence of around 5.8 at% of nitrogen. Our finding shows that large N‐doped bilayer graphene domains can be synthesized on the CuNi binary alloy.

Bulk δ15N measurements of organic‐rich rock samples by elemental analyzer/isotope ratio mass spectrometry with enhanced oxidation ability
Authors: Han Wennian , Feng Lianjun , Li Hongwei , Liu Wei 
Published: October 2016

RationaleElemental analyzer/isotope ratio mass spectrometry (EA/IRMS) has been widely used for nitrogen isotope ratio determination in various organic and inorganic samples. However, the extent of the redox reaction in the EA reaction tube can greatly affect the accuracy and precision of measurements, especially in the case of complex geological samples. It is therefore necessary to determine the appropriate reaction conditions to reach a high recovery of nitrogen by complete combustion or thermal decomposition and quantitative reduction.MethodsThe conventional Dumas dual‐inlet method was used to determine the bulk nitrogen isotope composition of SGR‐1 (an organic‐rich standard sample), which then was analyzed by EA/IRMS under different EA reaction conditions to study the influence of the redox environment on the δ15N measurements. The measured data together with the results reported by previous researchers were used to evaluate the effectiveness of the nitrogen extraction for organic‐rich rock samples.ResultsOur results demonstrated that with the Dumas dual‐inlet method more oxidizing agent (CuO) addition to SGR‐1 would yield a higher nitrogen content of 0.91% than the recommended content (0.81%) although a δ15N value of 17.39 ± 0.09‰ was consistent with the recommended value by USGS. Using EA/IRMS, when more O2 was injected in the reaction tube, a high nitrogen content (0.92 ± 0.01%) and a δ15N value (17.43 ± 0.17‰) close to that of the Dumas dual‐inlet method were obtained. The addition of V2O5 or CuO in a continuous‐flow system of EA/IRMS could not effectively enable the complete combustion of SGR‐1.ConclusionsWhen measuring the nitrogen isotope composition of organic‐rich rock sample dominated by reduced substances with EA/IRMS, greater O2 injection will enable more complete combustion to obtain reliable nitrogen yields compared with the addition of V2O5 or CuO.

Carbon isotope alteration during the thermal maturation of non‐flowering plant species representative of those found within the geological record
Authors: Smith Andrew C. , Kendrick Christopher P. , Moss‐Hayes Vicky L. , Vane Christopher H. , Leng Melanie J. 
Published: October 2016

RationaleThe carbon isotope (δ13C value) composition of fossil plant material is routinely used as a proxy of past climate and environment change. However, palaeoclimate interpretation requires assumptions about the stability of δ13C values in plant material during its decomposition and incorporation into sediments. Previous work on modern angiosperm species shows δ13C changes of several per mille during simulated decomposition experiments. However, no such tests have been undertaken on non‐flowering plants, which are found extensively within the geological record. These plants have distinctly different cellulose‐to‐lignin ratios from those of their angiosperm counterparts, potentially creating hitherto unknown variations in the original to fossil δ13C signatures.MethodsTo test the extent of δ13C change during decomposition we have subjected a number of plants, representing more basal, non‐flowering plant lineages (cycads, ferns, horsetails and dawn redwood), to artificial decay using a hydrothermal maturation technique at two temperatures over periods of up to 273 hours. Subsamples were extracted every 12–16 hours and analysed for their δ13C and %C values using a Carlo Erba 1500 elemental analyser, and VG TripleTrap and Optima mass spectrometers.ResultsThe %C values increased for all samples through the maturation process at both temperatures with the largest increases observed within the first 24 hours. Decreases in δ13C values were observed for all plants at 300°C and for two of the species at the lower temperature (200°C). The maximum shift in the δ13C value related to experimental decomposition was −0.90‰ (horsetail), indicating a preferential loss of 13C during thermal maturation.ConclusionsThe reduction in the δ13C value potentially suggests a preferential loss of isotopically heavier cellulose in relation to the isotopically lighter lignin component during maturation. The isotopic offset observed here (<0.9‰) means that palaeoclimatic interpretation of δ13C values from non‐flowering plant material within the geological record remains robust, but only where interpretations are based on variations in δ13C values greater than 1‰.
