Background
Systematizing reliable protocols and procedures for strength assessment in handball has allowed for a more thorough kinetic analysis and increased precision in detecting training-induced changes in muscular strength. The evaluation of upper limb strength with a bilateral standing press (BSP) exercise in handball players approximates blocking actions in the defensive phase, pushing and fixation.

Aim
The aim of this study was to analyze the relative and absolute reliability of intra-session comparisons in an isometric peak muscle strength protocol in a bilateral standing press (BSP) exercise among female handball players.

Methods
Sixteen young female handball players at an international level, aged between 22 ± 4 years, with no prior experience in using functional electromechanical dynamometers (FEMD) participated in this study. The participants initiated the assessment of maximum isometric force in a bipedal stance with a forward projection of the dominant foot between 20 and 30 cm. The knees were kept semi-flexed, and the hip extension of the non-dominant limb ranged from 15 to 20°. Bilateral anterior push of the upper limb was performed with shoulder abduction and elbow flexion at 90°, maintaining a pronated hand position. Participants were instructed to exert three sets of maximal force for 5 s in BSP exercise. Relative reliability was assessed using the model intraclass correlation (ICC) and absolute reliability was assessed using the coefficient of variation (CV) and standard error of measurement (SEM). For this study, the parameters of maximum and mean muscle strength were considered.

Results
The results demonstrated high relative reliability (ICC 0.93–0.97) and absolute reliability (SEM 0.19–2.79) y (CV 4.78–9.03) for both mean force and peak force, with no significant differences between the sets (p > 0.05), indicating a negligible effect size (0.01−0.12).

Conclusion
The mean and peak isometric muscle strength for the BSP exercise controlled with FEMD in female handball players exhibits high relative and absolute reliability between series.
Anthropogenic CO2 accumulation and uptake rates in the Pacific Ocean based on changes in the 13C/12C of dissolved inorganic carbon

Published: December 2016

AbstractThe anthropogenic CO2 accumulation rate for the Pacific Ocean was estimated from the decrease in δ13C of the dissolved inorganic carbon measured on six World Ocean Circulation Experiment cruises during the 1990s and repeated during Climate Variability and Predictability in the 2000s. A mean depth‐integrated anthropogenic δ13C change of −83 ± 20‰ m decade−1 was estimated for the basin by using the multiple linear regression approach. The largest anthropogenic δ13C decreases occurred between 40°S and 60°S, whereas the smallest decreases occurred in the Southern Ocean and subpolar North Pacific. A mean anthropogenic CO2 accumulation rate of 0.41 ± 0.13 mol C m−2 yr−1 (0.82 ± 0.26 Pg C yr−1) was determined based on observed δ13C changes and is in agreement with previous observation‐ and model‐based estimates. The mean dissolved inorganic carbon DIC13 inventory change of −178 ± 43‰ mol m−2 decade−1 was primarily the result of air‐sea CO2 exchange acting on the measured air‐sea δ13C disequilibrium of ~ −1.2 ± 0.1‰. Regional differences between the DIC13 inventory change and air‐sea 13CO2 flux yielded net anthropogenic CO2 uptake rates (independent of ΔpCO2) that ranged from ~0 to 1 mol m−2 yr−1 and basin‐wide mean of 1.2 ± 1.5 Pg C yr−1. High rates of surface ocean DIC increase and δ13C decrease observed in the Drake Passage (53°S–60°S) support above average anthropogenic CO2 accumulation since 2005. Observed δ13C changes in the Pacific Ocean indicate that ocean transport significantly impacted the anthropogenic CO2 distribution and illustrate the utility of δ13C as a tracer to unravel the processes controlling the present and future accumulation of anthropogenic CO2 in the ocean.

AbstractEin benzanelliertes Doppel‐[7]Carbohelicen (D7H) wurde durch regioselektive Cyclodehydrierung einer Tetranaphthyl‐p‐Terphenyl‐Vorstufe hergestellt. Die verdrillten Konformere D7H‐1 und D7H‐2 wurden durch Kristallisation getrennt, und ihre doppelte Helicenstruktur mit sich überlappenden terminalen Benzolringen wurde röntgenographisch aufgeklärt. Die hohe Isomerisierungsbarriere (46.0 kcal mol−1) der Doppelhelicene wurde mit Dichtefunktionaltheorie berechnet, wodurch sich eine sehr hohe Konformationsstabilität von D7H ergab. Die physikochemischen Eigenschaften von D7H‐1 und D7H‐2 wurden durch UV/Vis‐Spektroskopie und Cyclovoltammetrie untersucht. Die Ergebnisse zeigen die konformationsabhängigen Unterschiede in der jeweiligen elektronischen Struktur. Die Racematspaltung von D7H‐1 erfolgte durch HPLC an chiraler Phase, und die enantiomerenreinen Konformere D7H‐1‐(P,P) und D7H‐1‐(M,M) konnten isoliert sowie durch CD‐Spektroskopie charakterisiert wurden.

Published: December 2016

AbstractSwitching systems operating in a cooperative manner capable of converting light energy into mechanical motion are of great interest for optical devices, data storage, nanoscale energy converters and molecular sensing. Herein, photoswitchable monolayers were formed at the air–water interface from either a pure bis(thiaxanthylidene)‐based photoswitchable amphiphile or from a mixture of the photoswitchable amphiphile with a conventional lipid dipalmitoylphosphatidylcholine (DPPC). Efficient photoisomerization of the anti‐folded to syn‐folded geometry of the amphiphile's central core induces changes in the surface pressure in either direction, depending on the initial molecular density. Additionally, the switching behavior can be regulated in the presence of DPPC, which influences the packing of the molecules, thereby controlling the transformation upon irradiation. Bis(thiaxanthylidene)‐based photoswitchable monolayers provide a promising system to explore cooperativity and amplification of motion.
Invasive Hemodynamic Assessment During Mitra‐Clip Implantation
Authors: Cilingiroglu Mehmet , Marmagkiolis Konstantinos 
Published: December 2016

Key Points

Transesophageal echocardiography (TEE) assessment after MitraClip implantation is limited by unequal orifices and jets, eccentric regurgitation, and the acute change of the annulus geometry.
Periprocedural real‐time invasive hemodynamic assessment of the mitral valve function requires experience in hemodynamic monitoring interpretation. However, it provides excellent accuracy as it does not take into account the changes of the mitral apparatus geometry and jet direction after MitraClip placement.
While we seek to expand indications of Mitraclip to other patient subgroups, we should consider routine ancillary invasive hemodynamic assessment, in order to optimize our understanding, procedural results.

Published: December 2016

AbstractTin sulfide (SnS) nanoparticles were synthesized by pulsed laser ablation in liquid (PLAL) technique using an Nd:YAG laser operated at 532 nm. SnS thin films were deposited by spraying the colloidal suspension onto the heated substrates. The influence of different liquid media (dimethyl formamide and isopropyl alcohol) on the thin film properties were studied. Morphology, crystalline structure, and chemical composition of the nanoparticles were identified using transmission electron microscopy with energy dispersive X‐ray analysis. The crystalline structure of the thin films was analyzed by using grazing incidence X‐ray diffraction, and the chemical states by X‐ray photoelectron spectroscopy. Scanning electron microscopy was employed for the morphological analysis of the thin films. Annealing the films at 380 °C improved the crystallinity of the films exhibiting a layered morphology, which may be useful in optoelectronic and sensing applications. Cyclic voltammetry studies showed that the films have good electrochemical properties.

AbstractOptogenetics is a method that uses light to control cells in living tissue, typically neurons, that have been modified to express light‐sensitive ion channels and pumps. The approach facilitates neuromodulation in brain preparations and freely moving animals with unmatched spatial and temporal resolution. This optogenetics overview describes the vast array of light‐sensitive proteins available and the methods used to deliver them to tissue and modulate them with light. How these methods have so far enhanced our knowledge of fundamental neuroscience and psychiatric disease will be discussed as well as how they may contribute to drug discovery in the future. Finally, the potential rewards and risks of therapeutic gene transfer of optogenetic proteins in humans will be considered. © 2016 by John Wiley & Sons, Inc.
Porous Ionic Polymers as a Robust and Efficient Platform for Capture and Chemical Fixation of Atmospheric CO2

Published: December 2016

AbstractDirect use of atmospheric CO2 as a C1 source to synthesize high‐value chemicals through environmentally benign processes is of great interest, yet challenging. Porous heterogeneous catalysts that are capable of simultaneously capturing and converting CO2 are promising candidates for such applications. Herein, a family of organic ionic polymers with nanoporous structure, large surface area, strong affinity for CO2, and very high density of catalytic active sites (halide ions) was synthesized through the free‐radical polymerization of vinylfunctionalized quaternary phosphonium salts. The resultant porous ionic polymers (PIPs) exhibit excellent activities in the cycloaddition of epoxides with atmospheric CO2, outperforming the corresponding soluble phosphonium salt analogues and ranking among the highest of known metal‐free catalytic systems. The high CO2 uptake capacity of the PIPs facilitates the enrichment of CO2 molecules around the catalytic centers, thereby benefiting its conversion. We have demonstrated for the first time that atmospheric CO2 can be directly converted to cyclic carbonates at room temperature using a heterogeneous catalytic system under metal‐solvent free conditions. Moreover, the catalysts proved to be robust and fully recyclable, demonstrating promising potential for practical utilization for the chemical fixation of CO2. Our work thereby paves a way to the advance of PIPs as a new type of platform for capture and conversion of CO2.

Published: December 2016

AbstractA new class of hole‐transporting materials (HTM) containing tetraphenylmethane (TPM) core have been developed. After thermal, charge carrier mobility, and contact angle tests, it was found that TPA‐TPM (TPA: arylamine derivates side group) showed higher glass‐transition temperature and larger water‐contact angle than spiro‐OMeTAD with comparable hole mobility. Photoluminescence and impedance spectroscopy studies indicate that TPA‐TPM's hole‐extraction ability is comparable to that of spiro‐OMeTAD. SEM and AFM results suggest that TPA‐TPM has a smooth surface. When TPA‐TPM is used in mesoscopic perovskite solar cells, power conversion efficiency comparable to that of spiro‐OMeTAD is achieved. Notably, the perovskite solar cells employing TPA‐TPM show better long‐term stability than that of spiro‐OMeTAD. Moreover, TPA‐TPM can be prepared from relatively inexpensive raw materials with a facile synthetic route. The results demonstrate that TPM‐arylamines are a new class of HTMs for efficient and stable perovskite solar cells.
Indirect effects and prey behavior mediate interactions between an endangered prey and recovering predator

Published: December 2016

AbstractManaging for simultaneous recovery of interacting species, particularly top predators and their prey, is a longstanding challenge in applied ecology and conservation. The effects of sea otters (Enhydra lutris kenyoni) on abalone (Haliotis spp.) is a salient example along North America's west coast where sea otters are recovering from 18th‐ and 19th‐century fur trade while efforts are being made to recover abalone from more recent overfishing. To understand the direct and indirect effects of sea otters on northern abalone (H. kamtschatkana) and the relative influence of biotic and abiotic conditions, we surveyed subtidal rocky reef sites varying in otter occupation time in three regions of British Columbia, Canada. Sites occupied by sea otters for over 30 years had 16 times lower densities of exposed abalone than sites where otters have yet to recover (0.46 ± 0.08/20 m2 vs. 7.56 ± 0.98/20 m2), but they also had higher densities of cryptic abalone (2.17 ± 1.31/20 m2 vs. 1.31 ± 0.20/20 m2). Abalone densities were greater in deeper vs. shallower habitats at sites with sea otters compared to sites without otters. Sea otter effects on exposed abalone density were three times greater in magnitude than those of any other factor, whereas substrate and wave exposure effects on cryptic abalone were six times greater than those of sea otters. While higher substrate complexity may benefit abalone by providing refugia from sea otter predation, laboratory experiments revealed that it may also lead to higher capture efficiency by sunflower stars (Pycnopodia helianthoides), a ubiquitous mesopredator, compared to habitat with lower complexity. Sea otter recovery indirectly benefitted abalone by decreasing biomass of predatory sunflower stars and competitive grazing sea urchins, while increasing stipe density and depth of kelp that provides food and protective habitat. Importantly, abalone persisted in the face of sea otter recovery, albeit at lower densities of smaller and more cryptic individuals. We provide empirical evidence of how complex ecological interactions influence the effects of recovering predators on their recovering prey. This ecosystem‐based understanding can inform conservation trade‐offs when balancing multifaceted ecological, cultural, and socio‐economic objectives for species at risk.
A review of flavors authentication by position‐specific isotope analysis by nuclear magnetic resonance spectrometry: the example of vanillin
Authors: Remaud Gérald S. , Akoka Serge 
Published: December 2016

AbstractConsumers are increasingly interested in the authenticity and traceability of food products. This review aims at describing the principles of NMR Position‐Specific Isotopic Analysis and the applications and perspectives for aroma‐chemical authentication. Vanillin is an excellent example since, owing to its organoleptic qualities; it is undoubtedly one of the most used aroma‐chemicals in food, confectionery, beverages, perfumery, cosmetics and pharmaceutical industries. 2H‐NMR was first used, but it required several hours of spectrometer time and fairly large sample amounts. 13C NMR enabled the reduction of both the experimental time and the needed quantity of vanillin. Recent developments will soon make the analysis of vanillin possible in manufactured products. Copyright © 2016 John Wiley & Sons, Ltd.

Published: December 2016

ABSTRACTThe aim of this study was to investigate the effects of miR‐101‐3p on the viability, migration, invasion, and mitosis of lung squamous carcinoma cells by inhibiting EZH2. In this study, RT‐qPCR was used to detect the expression of miR‐101‐3p and EZH2 in both tissues and cells at RNA level. The dual luciferase reporter gene system was used to determine whether there was targeting relationship between miR‐101‐3p and EZH2‐3'UTR. Western Blot was used to detect the expression of EZH2 as well as the proliferation and invasion related proteins. The CCK‐8 assay, Transwell invasion assay, wound healing assay and flow cytometry were conducted to test the cell viability, invasion, migration and apoptosis. The results of RT‐qPCR and Western blot showed that miR‐101‐3p was low‐expressed and EZH2 was overexpressed in lung squamous cell carcinoma tissues and cells. Meanwhile the Western blot confirmed the effects of EZH2 expression on the proliferation and invasion of carcinoma cells. The results of luciferase assay and RT‐qPCR showed that miR‐101‐3p had a negative regulation effect on EZH2. The CCK‐8 assay, Transwell invasion assay, wound healing assay and flow cytometry results showed that the inhibition of EZH2 or the up‐regulation of miR‐101‐3p inhibited the viability, migration, invasion and cell cycle but promoted cell apoptosis of lung squamous cell carcinoma. MiR‐101‐3p could inhibit the viability, migration, invasion, and cell cycle of lung squamous carcinoma cells by inhibiting the EZH2. J. Cell.

AbstractBACKGROUNDThe sensory and head‐space profiles of Italian and Spanish commercial tomato sauces were investigated. The Flash Profiling method was used to evaluate sensory characteristics. Samples within each set were ranked according to selected descriptors. One hundred volatile compounds were identified by solid‐phase microextraction‐gas chomatography‐mass spectrometry.RESULTSFor Italian samples, the sensory notes of basil/aromatic herbs, acid and cooked tomato were among those perceived most by the assessors, whereas, in Spanish samples, the sensory attributes of garlic/onion and onion/sweet pepper and, in Italian samples, cooked tomato were among those found most frequently. Data were elaborated using multivariate statistical approaches and interesting correlations were observed among the different sensory attributes and related volatile compounds.CONCLUSIONSpanish samples were characterized by the highest content of volatiles linked to the thermal treatment of tomatoes and to raw and sautéed garlic and onion, whereas the Italian samples were characterized by terpenic compounds typical of basil and volatile molecules derived from fresh tomato. These results confirm the influence of both formulation and production processes on the aromatic profile (sensory attributes and volatile compounds) of tomato products, which is probably related to the different eating habits and culinary traditions in Italy and Spain. © 2016 Society of Chemical Industry

Published: December 2016

AbstractBACKGROUNDThe residue concentrations and dissipation rate of a new oxathiapiprolin fungicide in grapes and soil were investigated to provide an evaluation for the safe use of oxathiapiprolin in grapes. Pesticide residue was extracted by acetonitrile, then purified by solid‐phase extraction with an Envi‐Carb cartridge and determined by ultrahigh‐performance liquid chromatography–tandem mass spectrometry.RESULTSThe fortified recoveries ranged from 85.2% to 99.0%, with relative standard deviations of 1.7–4.5%. The limit of quantitation for oxathiapiprolin in grapes and soil was 0.002 mg kg−1. The mean initial deposits of oxathiapiprolin in grapes were 0.345–0.565 mg kg−1, with half‐lives of 8.6–9.2 days. The mean initial deposits of oxathiapiprolin in soil were 0.078–0.273 mg kg−1, with half‐lives of 7.6–12.0 days. The oxathiapiprolin residue in grapes and soil was 0.002–0.022 mg kg−1 and 0.002–0.123 mg kg−1 when sampling 14 days after application, respectively.CONCLUSIONThe residue in the grapes was less than 0.01 mg kg−1 when sampling 28 days after application, which suggested that the application rate of 20 mg a.i. kg−1 for this fungicide should be used to ensure that treated grapes can be considered safe for humans to consume when sampling 28 days after the final application. © 2016 Society of Chemical Industry
