Sea ice production variability in Antarctic coastal polynyas
Authors: Tamura Takeshi , Ohshima Kay I. , Fraser Alexander D. , Williams Guy D. 
Published: April 2016

AbstractEnhanced sea ice production (SIP) in Antarctic coastal polynyas forms dense shelf water (DSW), leading to Antarctic Bottom Water (AABW) formation that ultimately drives the lower limb of the meridional overturning circulation. Some studies suggest that the variability of SIP in Antarctic coastal polynyas is driven by the influence of atmospheric forcing, i.e., surface winds and air temperature. Our previous mapping of SIP in 13 major Antarctic coastal polynyas from 1992 to 2007, using a heat flux calculation with ice thickness data derived from satellite data, is extended here to examine the interannual and seasonal variability of SIP from 1992 to 2013. The interannual variability of total ice production correlates more strongly with polynya extent than with atmospheric forcing, with the exception of the Shackleton Polynya, which correlates well with wind. There is no coherent signal in the interannual variability between the major Antarctic coastal polynyas. We find that stochastic changes to the coastal “icescape,” i.e., ice shelves, floating glaciers, fast ice, together with offshore first‐year ice, are also important factors driving SIP variability on multiyear time scales. Both the Ross Ice Shelf Polynya and Mertz Glacier Polynya experienced a significant reduction in SIP due to calving events and the repositioning of icebergs and fast ice. Our results also show opposing trends between polynya‐based SIP and sea ice extent in key regions of Antarctic sea ice change. Close monitoring of coastal icescape dynamics and change is essential to better understand the long‐term impact of coastal polynya variability and its influence on regional AABW production.
Variation in climate sensitivity and feedback parameters during the historical period
Authors: Gregory J. M. , Andrews T. 
Published: April 2016

AbstractWe investigate the climate feedback parameter α (W m−2 K−1) during the historical period (since 1871) in experiments using the HadGEM2 and HadCM3 atmosphere general circulation models (AGCMs) with constant preindustrial atmospheric composition and time‐dependent observational sea surface temperature (SST) and sea ice boundary conditions. In both AGCMs, for the historical period as a whole, the effective climate sensitivity is ∼2 K (α≃1.7 W m−2 K−1), and α shows substantial decadal variation caused by the patterns of SST change. Both models agree with the AGCMs of the latest Coupled Model Intercomparison Project in showing a considerably smaller effective climate sensitivity of ∼1.5 K (α = 2.3 ± 0.7 W m−2 K−1), given the time‐dependent changes in sea surface conditions observed during 1979–2008, than the corresponding coupled atmosphere‐ocean general circulation models (AOGCMs) give under constant quadrupled CO2 concentration. These findings help to relieve the apparent contradiction between the larger values of effective climate sensitivity diagnosed from AOGCMs and the smaller values inferred from historical climate change.
Mitotic Spindle Assembly: The Roles of Microtubule Nucleation and Assembly
Authors: Xu Xiaowei , Luo Jia , Jiang Qing , Zhang Chuanmao 
Published: April 2016

Abstract

In all eukaryotes, the assembly of a bipolar mitotic spindle requires highly ordered arrangement of microtubule arrays. This process is facilitated by the formation of new microtubules and involves many proteins that regulate microtubule organisation and dynamics. While the γ‐tubulin ring complex (
γTuRC
) determines the spatial and temporal control over the initiation of microtubule growth, recent work reveals the molecular mechanisms behind these dynamic events.

Key Concepts

Mitotic spindle is a macromolecular temporary machine that initially assembles in early mitosis and disappears at the end of mitosis.

Mitotic spindle mainly consists of microtubules with a variety of microtubule‐associated proteins (MAPs) and motor proteins.

Microtubules are assembled from α/β‐tubulin heterodimers that contact both in longitudinal and lateral directions.

The MAPs and motor proteins take responsibility for regulating the growth or shrinkage of the microtubules.

Microtubule nucleation occurs at microtubule‐organising centres (MTOCs).

γ‐Tubulin and several other components assemble into γ‐tubulin ring complex (γTuRC) that determines when and where to nucleate the microtubule.

Diffusible RanGTP gradient from chromosomes facilitates chromosome‐mediated microtubule nucleation and assembly.

Microtubules may serve as nucleation sites for microtubule nucleation and assembly regulated by γTuRC and augmin protein complex.

Small microtubule seed/aster formation and sorting facilitate kinetochore capture by microtubules and mitotic spindle assembly.

Mitotic kinases such as cyclin‐dependent kinases, auroras and Plks regulate microtubule nucleation and assembly during mitotic spindle formation.
Brief Report: Comparing the Autobiographical Remembering of Iranian Immigrant Trauma Survivors with That of Iranian and British Trauma Survivors
Authors: Jobson Laura , Cheraghi Sepideh , Moradi Ali Reza 
Published: April 2016

SummaryThis study investigated how culture and posttraumatic stress disorder (PTSD) influence the autobiographical remembering of Iranian trauma survivors living in Britain compared to the remembering of British trauma survivors living in their host culture (Britain) and Iranians in their culture of origin (Iran). Iranian immigrants with and without PTSD completed measures of autobiographical remembering. Data was compared to previously collected data from British and Iranian trauma survivors with and without PTSD. It was found that the memory‐content of Iranian immigrants' memories resembled that of Iranian trauma survivors in Iran, while the phenomenological properties of their autobiographical remembering more closely resembled that of British trauma survivors. Moreover, there were pan‐cultural distortions and deficits in the autobiographical remembering of those with PTSD. The findings suggest that immigrants with PTSD have similar disruptions and distortions in their autobiographical remembering as that of individuals with PTSD living in their host culture and culture of origin.Copyright © 2016 John Wiley & Sons, Ltd.
Direct Conversion of Internal Alkynes into α‐Iodoenones: One‐Step Collaborative Iodination and Oxidation
Authors: Wang Youliang , Genoux Alexandre , Ghorai Subir , Chen Hongyi , Todd Robert , Zhang Liming 
Published: April 2016

AbstractThe reaction of an internal alkyne with 2,6‐dichloropyridine N‐oxide, a nucleophilic oxidant, and electrophilic N‐iodosuccinimide (NIS) simultaneously enables the direct access to versatile α‐iodoenones. Electronically biased internal alkynes undergo the one‐step transformation with excellent regioselectivities and with practical Z/E ratios. In comparison to the related oxidative gold catalysis using pyridine N‐oxides, this reaction employs NIS as the stoichiometric ynophile instead of the soft acidic noble metal catalyst and affords products featuring an additional versatile CI bond. Similar strategies for replacing ynophilic cationic gold(I) complexes in oxidative gold catalysis with likewise ynophilic stoichiometric electrophiles would enable the development of new synthetic methods.magnified image
Bioorthogonal Turn‐On Probe Based on Aggregation‐Induced Emission Characteristics for Cancer Cell Imaging and Ablation
Authors: Yuan Youyong , Xu Shidang , Cheng Xiamin , Cai Xiaolei , Liu Bin 
Published: April 2016

AbstractBioorthogonal turn‐on probes have been widely utilized in visualizing various biological processes. Most of the currently available bioorthogonal turn‐on probes are blue or green emissive fluorophores with azide or tetrazine as functional groups. Herein, we present an alternative strategy of designing bioorthogonal turn‐on probes based on red‐emissive fluorogens with aggregation‐induced emission characteristics (AIEgens). The probe is water soluble and non‐fluorescent due to the dissipation of energy through free molecular motion of the AIEgen, but the fluorescence is immediately turned on upon click reaction with azide‐functionalized glycans on cancer cell surface. The fluorescence turn‐on is ascribed to the restriction of molecular motion of AIEgen, which populates the radiative decay channel. Moreover, the AIEgen can generate reactive oxygen species (ROS) upon visible light (λ=400–700 nm) irradiation, demonstrating its dual role as an imaging and phototherapeutic agent.

Authors: Ngwabebhoh Fahanwi Asabuwa , Erdem Ahmet , Yildiz Ufuk 
Published: April 2016

ABSTRACTA comprehensive feasibility study on adsorption of Cu(II) and a water‐soluble nitrazine yellow (NY) dye by chitosan‐montmorillonite (CS‐MMT) hydrogel as the biosorbent was investigated as a function of biosorbent dosage, initial concentration, pH, temperature, and the presence of salts. Box–Behnken methodology was applied to optimize the adsorption experiments. Maximum adsorption values were determined as 132.74 mg/g and 144.41 mg/g at pH = 5.0, for Cu(II) and NY dye, respectively. Equilibrium isotherms of Langmuir and Freundlich were analyzed by the non‐linear regression model. The equilibrium data were well described by Freundlich model and the adsorption process well fitted pseudo‐second order kinetics. The enthalpy change of adsorption (ΔH°) were calculated as −3.78 kJ/mol and −5.75 kJ/mol for Cu(II) and NY dye, respectively, indicating that the adsorption processes were exothermic. © 2016 Wiley Periodicals, Inc.

Experimental and computational study of microfluidic flow‐focusing generation of gelatin methacrylate hydrogel droplets
Authors: Samanipour Roya , Wang Zongjie , Ahmadi Ali , Kim Keekyoung 
Published: April 2016

ABSTRACTThis work presents the experimental and computational study of droplet generation for hydrogel prepolymer solution in oil using a flow‐focusing device. Effects of different parameters on hydrogel droplet generation and droplet sizes in a flow‐focusing device were investigated experimentally and computationally. First, three dimensional (3D) computational simulations were conducted to describe the physics of droplet formation in each regime and mechanism of three different regimes: squeezing, dripping, and jetting regime of hydrogel were investigated. Subsequently, the effects of viscosity, inertia force, and surface tension force on droplet generation, and droplet size were studied through these experiments. The experiments were carried out using different concentration of gelatin methacrylate (GelMA) hydrogel (5 wt % and 8 wt %) as the dispersed phase and two different continuous phase liquids (light mineral oil and hexadecane) with various concentrations of surfactant (0 wt %, 3 wt %, and 20 wt %). All experimental data was summarized by capillary number of dispersed phases and the continuous phases to characterize the different regimes of droplet generation and to predict the transition of dripping to a jetting regime for GelMA solution in flow‐focusing devices. It is shown that the transition of dripping to a jetting regime for GelMA happens at lower capillary numbers compared to aqueous solutions. Moreover, by increasing the viscous force of continuous phase or decreasing the interfacial force, the size of GelMA droplets was decreased. By controlling these parameters, the droplet sizes can be controlled between 30 μm and 200 μm, which are very suitable for cell encapsulation. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Published: April 2016

ABSTRACTPolyamides were synthesized from a thiophene‐containing diamine by direct polycondensation with organosilane acyl dichlorides. The obtained polymers had good solubility in common organic solvents and THF, with TDT10% values upper than 400 °C and Tg between 150 and 180 °C. Combination of these properties reveals that the processability of the polymers was increased with respect to traditional aromatic polyamides. Inherent viscosity values and SEC analysis indicated low molecular weight species. Samples showed high visible transparency and bandgap values associated to insulating materials. Polymer solutions were deposited using electrospun technique and their surface properties were studied by SEM. Spheres were created according to electric field applied during deposition process. Low molecular weight and conductivity prevent charge accumulation in the surface hindering fibers generation. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43702.
Development of a degenerated TaqMan real‐time Q‐PCR for detection of bacteria‐free DNA in dialysis fluid
Authors: Bergallo Massimiliano , Loiacono Elisa , Rizzo Giovanna , Caiazzo Marialuisa , Palladino Giuseppe , Amore Alessandro 
Published: April 2016

AbstractBacterial‐derived DNA fragments (BDNAs) have been shown to be present in a dialysis fluid, to pass through dialyzer membranes, and to induce interleukin 6 (IL‐6) in mononuclear cells. DNA fragments are thought to be derived from microorganisms inhabiting hemodialysis water and fluid. The primary aim of the present study was to develop two degenerated TaqMan real‐time quantitative‐PCR (Q‐PCR) for detection of a broad range of bacterial DNA that specifically detect 16S ribosomal DNA (rDNA) (862 and 241 bp) and evaluate the efficiency of the Bellco Selecta resin to capture the BDNAs in the dialysis fluid. For this purpose, we decided to compare measurements of unfragmented samples (9.8 × 105 Escherichia coli genome) with artificially fragmented DNA samples. We assessed two broad‐range real‐time PCR targeting bacterial 16S rRNA genes for detection of fragmented and unfragmented bacterial DNA in the dialytic fluid and demonstrated that Bellco Selecta resin is capable of retaining these types of bacterial DNA.
Microcapsules and 3D customizable shelled microenvironments from laser direct‐written microbeads
Authors: Kingsley David M. , Dias Andrew D. , Corr David T. 
Published: April 2016

ABSTRACTMicrocapsules are shelled 3D microenvironments, with a liquid core. These core‐shelled structures enable cell–cell contact, cellular proliferation and aggregation within the capsule, and can be utilized for controlled release of encapsulated contents. Traditional microcapsule fabrication methods provide limited control of capsule size, and are unable to control capsule placement. To overcome these limitations, we demonstrate size and spatial control of poly‐l‐lysine and chitosan microcapsules, using laser direct‐write (LDW) printing, and subsequent processing, of alginate microbeads. Additionally, microbeads were used as volume pixels (voxels) to form continuous 3D hydrogel structures, which were processed like capsules, to form custom shelled aqueous‐core 3D structures of prescribed geometry; such as strands, rings, and bifurcations. Heterogeneous structures were also created with controlled initial locations of different cell types, to demonstrate the ability to prescribe cell signaling (heterotypic and homotypic) in co‐culture conditions. Herein, we demonstrate LDW's ability to fabricate intricate 3D structures, essentially with “printed macroporosity,” and to precisely control structural composition by bottom‐up fabrication in a bead‐by‐bead manner. The structural and compositional control afforded by this process enables the creation of a wide range of new constructs, with many potential applications in tissue engineering and regenerative medicine.

Published: April 2016

AbstractIntroductionHuman hippocampal tissue resected from pharmacoresistant epilepsy patients was investigated to study the effect of the antiepileptic drug CBZ (carbamazepine) and was compared to similar experiments in the hippocampus of control rats.MethodsThe molecular layer of the DG (dentate gyrus) of human epileptic tissue and rat nonepileptic tissue was electrically stimulated and the evoked responses were recorded with voltage‐sensitive dye imaging to characterize the spatiotemporal properties.ResultsBath applied CBZ (100 μmol/L) reduced the amplitude of the evoked responses in the human DG, albeit that no clear use‐dependent effects were found at frequencies of 8 or 16 Hz. In nonepileptic control DG from rats, CBZ also reduced the amplitude of the evoked response in the molecular layer of the DG as well as the spatial extent of the response.ConclusionsThis study demonstrates that CBZ still reduced the activity in the DG, although the patients were clinically diagnosed as pharmacoresistant for CBZ. This suggests that in the human epileptic brain, the targets of CBZ, the voltage‐gated Na+ channels, are still sensitive to CBZ, although we used a relative high concentration and it is not possibility to assess the actual CBZ concentration that reached the target in the patient. We also concluded that the effect of CBZ was found in the activated region of the DG, quite comparable to the observations in the nonepileptic rat.
Highly Stereocontrolled Ring‐Opening Polymerization of Racemic Alkyl β‐Malolactonates Mediated by Yttrium [Amino‐alkoxy‐bis(phenolate)] Complexes

Published: April 2016

AbstractYttrium [amino‐alkoxy‐bis(phenolate)]amido complexes have been used for the ring‐opening polymerization (ROP) of racemic alkyl β‐malolactonates (4‐alkoxycarbonyl‐2‐oxetanones, rac‐MLARs) bearing an allyl (All), benzyl (Bz) or methyl (Me) lateral ester function. The nature of the ortho‐substituent on the phenolate rings in the metal ancillary dictated the stereocontrol of the ROP, and consequently the syndiotactic enrichment of the resulting polyesters. ROP promoted by catalysts with halogen (Cl, Br)‐disubstituted ligands allowed the first reported synthesis of highly syndiotactic PMLARs (Pr ≥ 0.95); conversely, catalysts bearing bulky alkyl and aryl ortho‐substituted ligands proved largely ineffective. All polymers have been characterized by 1H and 13C{1H} NMR spectroscopy, MALDI‐ToF mass spectrometry and DSC analyses. Statistical and thermal analyses enabled the rationalization of the chain‐end control mechanism. Whereas the stereocontrol of the polymerization obeyed a Markov first‐order (Mk1) model for the ROP of rac‐MLABz and rac‐MLAAll, the ROP of rac‐MLAMe led to a chain end‐control of Markov second‐order type (Mk2). DFT computations suggest that the high stereocontrol ability featured by catalysts bearing Cl‐ and Br‐substituted ligands does not likely originate from halogen bonding between the halogen substituent and the growing polyester chain.
