Bridging disciplines with training in remote sensing for animal movement: an attendee perspective
Authors: Clark Bethany L. , Bevanda Mirjana , Aspillaga Eneko , Jørgensen Nicolai H. 
Published: August 2016

AbstractRemote sensing and animal movement datasets are increasingly used to answer key questions in ecology and conservation. Collecting and accessing this data is becoming ever cheaper and easier, but limited analytical expertise limits its wider use. Working at the interface between these two disciplines is challenging as there are no standard techniques for handling the complex spatial data, so specific and in‐depth training is required. Higher education programs rarely cover remote sensing for animal movement, so external courses play a major role in training newcomers and creating a more unified global community. We conducted an online survey to investigate the views of previous attendees of four training courses that involve remote sensing and animal location data. These courses provided subject‐specific knowledge, practical and coding skills, networking, collaboration opportunities, insightful discussions and transferable research skills. Our survey highlighted the importance of real‐world examples, practical sessions, time for participants to work with their own data, preparatory material and open source software. Despite the value of interdisciplinary training in remote sensing and animal movement, it reaches few ecology and conservation practitioners outside of academia. We advocate more funding for underrepresented participants to attend existing course and the development of new courses.

Published: August 2016

AbstractWaste corn‐cob cellulose supported poly(amidoxime) palladium nanoparticles (PdNs@PA) were prepared by the surface modification of waste corn‐cob cellulose through graft co‐polymerization and subsequent amidoximation. The supported nanoperticles showed high catalytic activity (45‐400 mol ppm) towards Suzuki‐Miyaura cross‐coupling of aryl bromides/chlorides with organoboronic acids to give the corresponding biaryl products up to 99 % yield with high turnover number (TON) 19777 and turnover frequency (TOF) 4944 h−1. The PdNs@PA was easily recovered from the reaction mixture and reused several times without significant loss of its catalytic activity.

Published: August 2016

AbstractIn the recent past, various catalysts have been used for hydrogenation of benzaldehyde to benzyl alcohol and the efficiency of the catalysts observed is found to be less.This review focuses on catalytic hydrogenation and their parameters associated with supports, methods of preparation, solvents involved, reaction conditions in converting benzaldehyde to benzyl alcohol. Critical aspect of review is to evaluate activities of various heterogeneous catalysts that can selectively reduce benzaldehyde to benzyl alcohol. The catalysts include various transition (Ni, Cu, Co) and noble metals (Au, Pt, Pd, Ru), monoliths and metal oxides (MgO, CaO, BaO, Al2O3, CeO2, ZrO2, etc.,), which are all active in the reaction. Among the transition metals, cobalt‐based catalysts depicted promising activity, while ruthenium‐based systems demonstrated spectacular activity among noble metal series. Hydrogenation by electrochemical reduction using platinum, palladium, nickel has also been reviewed.

Published: August 2016

AbstractFRET forms the basis for energy transfer in biological systems and organisms and it has become an investigative tool in the analysis of protein‐protein interactions and in the study of semiconductors (SC). Until now, FRET has been restricted to the simultaneous presence of both components in the same phase. Here, we report on the first successful prototype demonstrating interfacial FRET. This innovative FRET between inorganic SC‐nanoparticles and illuminating protein chimeras takes place across an oil/water interface. As a ′proof of concept′ oil droplets were stabilized by hydrophobin‐derivatives in aqueous solution. These proteins possess the ability to attach fused functional domains close to an interface. Moreover, an optically active nanostructure directly docks to the hydrophobin at the oil/water interface. Due to its modular design, this signal amplification array has the potential to be exploited in numerous fields ranging from biosensors, biotechnology to medical applications.

Published: August 2016

AbstractBenzoxazine resins, although exhibiting attractive properties; particularly high thermal stability and near zero‐ shrinkage, suffer from a major drawback associated with its high curing temperature. In view of the Lewis acidity associated with the Zn4O nodes in a zinc based metal organic framework [Zn4O(BDC)3, MOF5], we considered it of interest to explore its potential as a curing accelerator for a representative biobased benzoxazine resin. MOF 5 was solvothermally synthesized and characterized using different techniques including powder X‐ray diffraction (PXRD), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), Fourier transform infrared spectroscopy (FT‐IR) and Nitrogen physisorption measurements. Bio‐based benzoxazine resin was synthesized by mannich type condensation of cardanol and aniline with formaldehyde under solventless conditions, the structure of which was confirmed using FT‐IR and 1H‐NMR. The curing behavior of the synthesized resin was systematically investigated using non‐isothermal Differential Scanning Calorimetry (DSC). Introduction of MOF 5 led to a shift in the curing profile to lower temperature, the extent of which was proportional to the amount of MOF 5 in the formulation. DSC studies were performed at different heating rates to establish the kinetic parameters associated with the curing of the resin. Activation energy, as calculated using Kissinger Akahira Sunose method, was found to concomitantly decrease from 98 kJ/mol to 58 kJ/mol upon addition of MOF 5 (5 % w/w).

Published: August 2016

AbstractHere, we demonstrate the fabrication of binder free and very efficient supercapacitor electrodes based on MnO2 nanorods on silver (Ag) coated porous anodic aluminum oxide (AAO) substrate in a very simple way by DC magnetron sputtering. The Ag coated porous AAO substrate acts as excellent current collector and also enhances high specific capacitance of MnO2 up to ∼796 F/g. A symmetric supercapacitor device in form of α‐MnO2 nanorods/Ag/AAO electrode has been fabricated, characterized and its performance has been investigated in detail. The binder free supercapacitor device delivered a high capacitance (132 F/g), good cycling ability (95.52 % capacitance retention after 3000 cycles), high energy density (26.4 Wh/kg), and also a high power density (∼36 kW/kg at 6 Wh/kg) in a voltage range of 1.3 V. These observed excellent electrochemical performances of the present MnO2 nanorods based device, suggest it tremendous potential as supercapacitor electrodes in energy storage applications.

AbstractFluorescein dye bearing imidazole has been designed and synthesized as an effective colorimetric and ‘‘turn on’’ fluorescent sensor for Zn2+. The probe FI‐1 shows selective and dramatic colour change from colourless to yellow and fluorescence turn‐on response for Zn2+ with greater sensitivity. 1H NMR titration experiments confirms that the binding of Zn2+ ions leads to the spirolactam ring opening that causes change in absorbance and fluorescence. Density functional theory calculations also support the observed photophysical changes. The applicability of the probe for Zn2+ detection was shown by the live cell imaging in HeLa cells. Further the probe utilized for imaging of Zn2+ ions liberated during apoptosis.
High‐Performance LiCoO2 Sub‐Micrometer Materials from Scalable Microparticle Template Processing
Authors: Qi Zhaoxiang , Koenig Gary M. 
Published: August 2016

AbstractOne attribute that has limited performance for some lithium‐ion battery active material systems is large particle size. While many methods have been reported in the literature for producing high‐performance sub‐micrometer sized battery particles, often these procedures are difficult to adapt to large battery electrode powder production and/or the processing is relatively expensive compared to traditional methods. We report a highly scalable process to produce high performance sub‐micrometer battery active material using an initial demonstration cathode chemistry, LiCoO2 (LCO). We adopted a template‐based process which took advantage of a cobalt oxalate precursor material with a rod morphology. Lithiation of the precursor via calcination produced loosely connected sub‐micrometer sized LCO particles which were easily dispersed into individual particles through a low energy mechanical method. The sub‐micrometer sized LCO particulates exhibited excellent electrochemical performance as lithium‐ion battery cathode active materials, including high discharge capacity, rate capability, and coulombic efficiency.

Published: August 2016

AbstractA series of gold(I) selenolates viz., [Au(Sepy‐2)(PPh3)] (1), [Au(Sepy‐4)(PPh3)] (2) (py=pyridyl), [Au(Sepyz‐2)(PPh3)] (3) (pyz=pyrazinyl), [Au(Sepym‐2)(PPh3)] (4) (pym=pyrimidyl) and [Au{Sepym(Me2‐4,6)‐2}(PPh3)] (5) {pym‐2‐(Me2‐4,6)=4,6‐dimethyl‐2‐pyrimidyl} have been synthesized and structurally characterized. The gold atom acquires a two‐coordinate linear geometry with Au−Se distance of ∼ 2.41 Å. The existence of aurophilic interactions are determined by the nature of substituent on selenium. It was observed that the complexes derived from selenolate ligand with pyridyl moiety (one hetero‐N atom in the ring) could exhibit aurophilicity; whereas, the complexes derived from ligands containing pyrazinyl and pyrimidyl moieties (two hetero‐N atoms) are devoid of such interaction but show secondary Au⋅⋅⋅N interaction. The complex [Au(Sepy‐4)(PPh3)] shows polymorphism and the two polymorphs differ in the relative orientations of linear molecules. There are competing secondary intramolecular Au⋅⋅⋅N interaction which plays crucial role on intermolecular aurophilic interaction and overall structure. Theoretical calculations at DFT and MP2 levels have been carried out to rationalize the experimental findings.

Myelin Basic Protein Regulates Primitive and Definitive Neural Stem Cell Proliferation from the Adult Spinal Cord

Published: August 2016

Abstract
The adult mammalian forebrain comprises two distinct populations of neural stem cells (NSCs): rare, Oct4 positive, primitive NSCs (pNSCs) and definitive NSC (dNSC) which are more abundant and express GFAP. The pNSCs are upstream of the dNSCs in the neural stem cell lineage. Herein we show that pNSC and dNSC populations can also be isolated from the developing and adult spinal cord. Spinal cord derived pNSCs are similarly rare, Oct4 expressing cells that are responsive to leukemia inhibitory factor and dNSCs are 4-5X more abundant and express GFAP. We demonstrate that myelin basic protein (MBP) is inhibitory to both pNSC and dNSC derived colony formation. Similar to what is seen in the adult forebrain following injury, spinal cord injury results in a significant increase in the size of the dNSC and pNSC pools. Hence, both primitive and definitive neural stem cells can be isolated from along the embryonic and adult neuraxis in vivo and their behavior is regulated by MBP and injury.
Dynamics of Mechanosensitive Neural Stem Cell Differentiation

Published: August 2016

Abstract
Stem cell differentiation can be highly sensitive to mechanical inputs from the extracellular matrix (ECM). Identifying temporal windows during which lineage commitment responds to ECM stiffness, and the signals that mediate these decisions, would advance both mechanistic insights and translational efforts. To address these questions, we investigate adult neural stem cell (NSC) fate commitment using an oligonucleotide-crosslinked ECM platform that for the first time offers dynamic and reversible control of stiffness. “Stiffness pulse” studies in which the ECM was transiently or permanently softened or stiffened at specified initiation times and durations pinpoint a 24-hour window in which ECM stiffness maximally impacts neurogenic commitment. Overexpression of the transcriptional coactivator Yes-associated protein (YAP) within this window suppressed neurogenesis, and silencing YAP enhanced it. Moreover, ablating YAP-β-catenin interaction rescued neurogenesis. This work reveals that ECM stiffness dictates NSC lineage commitment by signaling via a YAP and β-catenin interaction during a defined temporal window.

Abstract
Human umbilical cord blood derived mesenchymal stem cells (uMSC) are pluripotent cells that have been now considered as a promising candidate for various cell-based therapies. However, their limited in vitro proliferation ability and the gradual loss of pluripotency set barricades for further usages. Emerging evidence suggests that small nucleolar RNAs (snoRNA) are actively involved in cell proliferation especially in tumor cells, but their roles in stem cells are largely unknown. In this study, we demonstrated that H/ACA box small nucleolar RNA 7A (SNORA7A) is inversely correlated to the decreased proliferation rate during in vitro passaging of uMSC. Further investigations indicate that SNORA7A overexpression can promote uMSC proliferation and self-renewal. The inhibition of SNORA7A using antisense oligonucleotides significantly reduces the expression and the binding of SNORA7A to DKC1, core protein that essential to form small nucleolar ribonucleo-particles (snoRNP) complex and catalyze pseudouridines in 28S RNA. And the inhibition also significantly suppresses uMSC proliferation and self-renewal. Moreover, overexpression of SNORA7A transcripts with mutations of binding regions for snoRNP core proteins and 28S RNA did not induce proliferation and self-renewal. Besides, SNORA7A also suppresses both the osteogenic and adipogenic differentiation, strengthening its self-renewal maintaining roles in uMSC. Taken together, our study for the first time showed that H/ACA box snoRNAs are actively involved in MSC proliferation as well as pluripotency control, and we identify SNORA7A as one of the critical snoRNAs that regulate the proliferation and self-renewal of uMSC through snoRNP recruiting.
Spent lead shot availability and ingestion by ring‐necked pheasants in South Dakota
Authors: Runia Travis J. , Solem Alex J. 
Published: August 2016

ABSTRACTLead is toxic to all vertebrate species and ingestion of lead ammunition has been reported in >130 avian species. Research has primarily focused on the effects and exposure of spent lead shot on waterfowl with little information about effects on upland game species, such as ring‐necked pheasant (Phasianus colchicus). We collected 1,450 soil samples to estimate the availability of lead shot on 2 licensed shooting preserves in South Dakota, USA, 2012–2013. We concurrently collected gizzards from 660 hunter‐harvested wild male pheasants from the shooting preserves and compared lead ingestion rates with those of 1,301 gizzards collected from nonpreserve areas. Spatial modeling showed the distribution of spent lead shot was associated with the systematic hunting pattern of each study site and, to a lesser extent, land‐use type. Prevalence of ingested lead shot was 4.9 times greater for birds harvested on shooting preserves (3.9%, 95% CI = 2.7–5.7%) when compared with nonpreserve areas (0.8%, 95% CI = 0.4–1.4%) where lead shot availability was presumed less. Wild pheasants inhabiting areas of artificially high hunting intensity and lead deposition are at elevated risk of lead exposure and poisoning, although the consequences of lead ingestion in wild pheasants are unknown. © 2016 The Wildlife Society.
Landscape design: Integrating ecological, social, and economic considerations into conservation planning
Authors: Bartuszevige Anne M. , Taylor Kyle , Daniels Alex , Carter Michael F. 
Published: August 2016

ABSTRACTLandscape design is a conservation planning process, described in the landscape ecology literature, proposed to rectify the knowledge and implementation gap in planning that have limited the effectiveness of many conservation planning efforts. Use of landscape design bridges this gap through increased emphasis on the interdisciplinary nature of conservation planning and engagement of a stakeholder advisory team to create a conservation plan that resonates with biological, cultural, social, and economic realities of the area concerned. We define landscape design as a conservation planning process that integrates societal goals and values with established biological conservation goals, using science grounded in landscape ecology to describe future scenarios where specific and measurable biological goals can be attained. First, we describe a landscape design process and provide examples from the literature and partnerships such as Connect the Connecticut and the Appalachian Landscape Conservation Cooperative. We follow by discussing a case study of a landscape design effort to conserve playa wetlands to support waterfowl goals for migrating waterfowl established in the North American Waterfowl Management Plan. We further highlight characteristics of a successfully completed landscape design. We conclude that landscape design is a powerful process that goes beyond identifying high‐priority conservation assets and intended to be an action‐oriented process. Landscape design provides a framework for ensuring that conservation planning does not occur in a vacuum by ensuring social, cultural, and economic needs of people are recognized before valuable conservation dollars are expended. It provides a mechanism for understanding the effects of future landscape drivers on natural resources and engages stakeholders in proactive discussions regarding conservation. The final result is a commitment by a partnership to a set of actions that will achieve the stated conservation goal. © 2016 The Wildlife Society.

Authors: Brüggemann Thomas , Dahlke Daniel , Chebbo Amin , Neumann Ilka 
Published: August 2016

Abstract
Implantable cardioverter–defibrillators (ICD) have to reliably sense, detect, and treat malignant ventricular tachyarrhythmias. Inappropriate treatment of non life-threatening tachyarrhythmias should be avoided. This article outlines the functionality of ICDs developed and manufactured by BIOTRONIK. Proper sensing is achieved by an automatic sensitivity control which can be individually tailored to solve special under- and oversensing situations. The programming of detection zones for ventricular fibrillation (VF), ventricular tachycardia (VT), and zones to monitor other tachyarrhythmias is outlined. Dedicated single-chamber detection algorithms based on average heart rate, cycle length variability, sudden rate onset, and changes in QRS morphology as used in ICDs by BIOTRONIK are described in detail. Preconditions and confirmation algorithms for therapy deliveries as antitachycardia pacing (ATP) and high energy shocks are explained. Finally, a detailed description of the dual-chamber detection algorithm SMART is given. It comprises additional detection criteria as stability of atrial intervals, 1:1 conduction, atrial–ventricular (AV) multiplicity, AV trend, and AV regularity to differentiate between ventricular and supraventricular tachyarrhythmias.

Zusammenfassung
Die Analyse epigenetischer Marker aus Liquid Biopsies erlaubt Einblicke in physiologische und pathologische Prozesse im Körper einer Person, die über die reine Sequenzinformation hinausgehen. Insbesondere das DNA-Methylierungsmuster sowie die Expressionsmuster von mRNA und ncRNA sind aus Liquid Biopsies erfassbar. Damit werden ganze Gruppen neuer potenzieller Biomarker einer nicht invasiven und ökonomischen Diagnostik zugänglich. Darüber hinaus und im Gegensatz zur reinen DNA-Sequenzanalyse von Liquid Biopsies erlaubt die hohe Gewebespezifität epigenetischer Marker auch die Bestimmung der Herkunft der analysierten Nukleinsäuren z. B. in Bezug auf ein betroffenes Organ. Angesichts der fallenden Kosten für Sequenzierungen und des technologischen Fortschritts, der die Nachweisgrenzen immer weiter zu immer sensitiveren Anwendungen verschiebt, könnten epigenetische Untersuchungen aus Liquid Biopsies den Trend zu einer Individualisierung in der Medizin weiter forcieren.
