Abstract
With regard to laparoscopic and robotic abdominoperineal resection (APR) for primary rectal malignancies, limited data have been published in the literature. Single-incision laparoscopic surgery (SLS) has been successfully introduced for treating colorectal cancer. Here we describe our experience of APR with SLS plus one port (SLS + 1) for treating advanced rectal cancer. A 65-year-old man underwent the procedure, which involved a 35-mm incision in the left side of the umbilicus for the insertion of a single multichannel port as well as the insertion of a 5-mm port into the right lower quadrant. The sigmoid colon and rectum were mobilized from the pelvic floor using a medial and lateral approach. After the rectum with the mesorectum was completely mobilized according to the total mesorectal excision, the sigmoid colon was intracorporeally transected. The specimen was removed through the perineal wound. Terminal colostomy was fashioned at the left lower trocar site. Lateral pelvic lymph node dissection was bilaterally performed. There were no perioperative complications. The total operating time was 592 minutes, and the estimated blood loss was 180 mL. To our knowledge, this is the first reported case of SLS + 1 APR with lateral pelvic lymph node dissection for treating rectal cancer. We conclude that SLS + 1 APR is a technically promising alternative method for treating selected patients with advanced rectal cancer.
Projected increase in diurnal and interdiurnal variations of European summer temperatures

Published: January 2015

AbstractBeyond the mean warming, climate change may modify the temperature variability, with consequences on extreme events causing societal and environmental impacts. Here we assess future changes in both the interdiurnal variability (ITV) and diurnal range (DTR) of European summer temperatures based on Fifth Phase of the Coupled Model Intercomparison Project projections under three 21st century scenarios. Both indices are projected to increase, with a rather good model agreement on the sign, while uncertainties remain on the amplitude. Extremely high day‐to‐day and diurnal temperature variations are expected to occur more frequently. Across models and scenarios, ITV and DTR increases vary primarily as functions of the decrease in surface evapotranspiration linked to the European summer drying. They are also partly explained by changes in the atmospheric dynamics and the surface cloud radiative effect. Model‐dependent degrees of control of (i) ITV and DTR by mean temperature and (ii) surface evapotranspiration by soil moisture appear as helpful metrics to reduce future uncertainties in ITV and DTR projections.
Investigating storm‐enhanced density and polar tongue of ionization development during the 22 October 1999 great storm
Authors: Horvath Ildiko , Lovell Brian C. 
Published: January 2015

AbstractWe investigate large‐scale plasma density increases occurring during the 22 October 1999 great storm and focus on storm‐enhanced density (SED) and polar tongue of ionization (TOI) development. Observations include two‐hourly Global Ionosphere Map series coupled with multi‐instrument in situ, space‐based, and ground‐based data plots, with Super Dual Auroral Radar Network two‐cell convection maps and with model‐generated neutral wind vector maps. Results demonstrate the equatorial electrojet events occurring in the Australian and American sectors, the high‐density plasma features, and their underlying plasma transportation processes. During the main phase, a series of four prompt penetration electric field (PPEF) events occurred with subauroral polarization stream E field development forming a plasmaspheric drainage plume. These E field events caused the repeated development of equatorial ionization anomaly (EIA), SED bulge, and SED plume during the local dusk‐midnight hours in those sectors that covered these local times. Showing a westward movement in accordance with their local time dependence, the EIA‐SED structure developed first in the American sector, later on over the Pacific, and finally in the Australian sector. The SED plume plasma found its way into the polar cap through the dayside cusp region, created in the north some large polar cap enhancements reaching up to seven times of the quiet time levels, and evolved in each hemisphere into a polar TOI. We speculate that the enhanced growth of EIA, transporting high‐density solar‐produced plasma to the SED bulge via strong net eastward E field effects, and the mechanical effects of equatorward neutral winds contributed to the polar TOI's increasingly better development.
Particle friction angles in steep mountain channels
Authors: Prancevic Jeff P. , Lamb Michael P. 
Published: January 2015

AbstractSediment transport rates in steep mountain channels are typically an order of magnitude lower than predicted by models developed for lowland rivers. One hypothesis for this observation is that particles are more stable in mountain channels due to particle‐particle interlocking or bridging across the channel width. This hypothesis has yet to be tested, however, because we lack direct measurements of particle friction angles in steep mountain channels. Here we address this data gap by directly measuring the minimum force required to dislodge sediment (pebbles to boulders) and the sediment weight in mountain channels using a handheld force gauge. At eight sites in California, with reach‐averaged bed angles ranging from 0.5° to 23° and channel widths ranging from 2 m to 16 m, we show that friction angles in natural streams average 68° and are 16° larger than those typically measured in laboratory experiments, which is likely due to particle interlocking and burial. Results also show that larger grains are disproportionately more stable than predicted by existing models and that grains organized into steps are twice as stable as grains outside of steps. However, the mean particle friction angle does not vary systematically with bed slope. These results do not support systematic increases in friction angle in steeper and narrower channels to explain the observed low sediment transport rates in mountain channels. Instead, the spatial pattern and grain‐size dependence of particle friction angles may indirectly lower transport rates in steep, narrow channels by stabilizing large clasts and channel‐spanning steps, which act as momentum sinks due to form drag.

Published: January 2015

AbstractThe hydrography of the Indian‐Atlantic Ocean gateway has been connected to high‐latitude climate dynamics by oceanic and atmospheric teleconnections on orbital and suborbital timescales. A wealth of sedimentary records aiming at reconstructing the late Pleistocene paleoceanography around the southern African continent has been devoted to understanding these linkages. Most of the records are, however, clustered close to the southern South African tip, with comparatively less attention devoted to areas under the direct influence of frontal zones of the Southern Ocean/South Atlantic. Here we present data of the composition and concentration of the diatom assemblage together with bulk biogenic content and the alkenone‐based sea surface temperature (SST) variations for the past 350 kyr in the marine sediment core MD02‐2588 (approximately 41°S, 26°E) recovered from the southern Agulhas Plateau. Variations in biosiliceous productivity show a varying degree of coupling with Southern Hemisphere paleoclimate records following a glacial‐interglacial cyclicity. Ecologically well‐constrained groups of diatoms record the glacial‐interglacial changes in water masses dynamics, nutrient availability, and stratification of the upper ocean. The good match between the glacial maxima of total diatoms concentration, Chaetoceros spores abundance, and opal content with the maximum seasonal cover of Antarctic ice and the atmospheric dust records points to a dominant Southern Hemisphere forcing of diatom production. Suborbital variability of SST suggests rapid latitudinal migrations of the Subtropical Front and associated water masses over the southern Agulhas Plateau, following millennial contractions and expansions of the subtropical gyres. Warmings of the upper ocean over site MD02‐2588 during terminations IV to I occurred earlier than that in the Antarctic Vostok, which is indicative of a Northern Hemisphere lead. Our multiparameter reconstruction highlights how high‐latitude atmospheric and hydrographic processes modulated orbital highs and lows in primary production and SST as triggered by northward transport of Si, eolian dust input, and latitudinal migrations of frontal zones.
New insights into productivity and redox‐controlled trace element (Ag, Cd, Re, and Mo) accumulation in a 55 kyr long sediment record from Guaymas Basin, Gulf of California

Published: January 2015

AbstractA high‐resolution, 55 kyr long record of chalcophile and redox‐sensitive trace element accumulation (Ag, Cd, Re, and Mo) from MD02‐2515, western Guaymas Basin, is investigated in conjunction with patterns in stratigraphy and productivity. High opal concentrations (~59 wt. %), representing increased diatom production, coincide with laminated sediments and dilute the concentrations of organic carbon (Corg) and metals. A similarity between opal and normalized Corg, Ag, and Cd concentrations suggests delivery to the sediments by diatom export production, while patterns in normalized Re and Mo accumulation suggest a different emplacement mechanism. Although Mo enrichment in organic‐rich, laminated sediments typically represents anoxic conditions at other locations, Mo (and Re) in Guaymas Basin is enriched in nonlaminated and bioturbated sediments that are representative of oxygenated conditions. Adsorption onto Fe‐ and/or Mn‐oxyhydroxide surfaces during oxygenation inadequately explains both the Re and Mo enrichments. Thus, recently published mechanisms invoking direct Re and Mo removal from the water column and bioturbation‐assisted irrigation of Re into the sediments are used to explain the counterintuitive observations in Guaymas Basin. The MD02‐2515 stratigraphic and proxy records are also different from other records in the northeast Pacific in that there is little correspondence with Greenland Dansgaard‐Oeschger interstadials. There is some correlation with Heinrich events, suggesting that ventilation of intermediate waters and/or reduced productivity may be important in controlling stratigraphy and trace element accumulation. The results question whether MD02‐2515 records can be compared to northeast Pacific open‐margin records, especially before 17 kyr B.P.
Consumer Culture Theory (CCT)
Authors: Askegaard Søren 
Published: January 2015

AbstractConsumer culture theory (CCT) is a stream of research focusing on consumption patterns as a social and cultural practice. Scholars who espouse CCT are predominantly, albeit not exclusively, employed in marketing or management departments in universities and business schools in Europe and North America, though there is a growing interest in this type of research in Latin America, for example. Based on the legacy of earlier social psychological approaches to the symbolic nature of consumer behavior as expressed in, for example, the work of Sidney Levy from the 1950s, CCT slowly grew from the early 1980s onward as an increasingly significant addition to the traditional econometric and cognitive psychological approaches to the study of consumer decision making and consumer behavior in business schools.
Gay and Lesbian/Queer Markets/Marketing
Authors: Campbell John Edward 
Published: January 2015

Abstract
“Gay marketing” or “gay and lesbian marketing” refers to advertising campaigns designed to appeal to gay male and/or lesbian consumers, whether these advertisements are explicit or coded. The term “gay marketing” can be used to indicate advertising campaigns aimed specifically at gay male consumers, lesbian consumers, or gay male and lesbian consumers more broadly. Gay marketing appeals take the form of advertisements or sponsored content in gay‐oriented publications and on gay‐oriented websites, direct mail solicitations, coded advertisements appearing in the commercial media, and, more recently, open appeals to gay consumers in the mainstream media. The historical development of gay marketing is fundamentally intertwined with the emergence of national gay publications.
Music and Consumer Experience
Authors: Lang John T. 
Published: January 2015

Abstract
Consumers are besieged by music. Corporations use music to shape consumer experience and purchasing behaviors, to build emotional connections with consumers, and to enhance the corporate brand image. Music provides a set of aesthetic and commercial cues, beyond visual and other sensory practices, for consumers and corporations. In this manner, music is intricately intertwined with commercial symbols, practices, and environments.

Published: January 2015

AbstractTwo highly stereoselective radical‐mediated syntheses of densely functionalized indanes and dibenzocycloheptadienes from ortho‐vinyl‐ and ortho‐vinylaryl‐substituted N‐(arylsulfonyl)‐acrylamides, respectively, are presented here. The chemoselective addition of in situ generated radicals (X.) onto the styrene moieties triggers an unprecedented reaction cascade, resulting in the formation of one new CX bond and two new CC bonds, a formal 1,4‐aryl migration, and the extrusion of SO2 to generate an amidyl radical intermediate. This intermediate, upon H abstraction, leads to the observed 5‐ and 7‐membered ring carbocyclic products, respectively, in a highly efficient manner.
Structure of the Sulfoxide Synthase EgtB from the Ergothioneine Biosynthetic Pathway
Authors: Goncharenko Kristina V. , Vit Allegra , Blankenfeldt Wulf , Seebeck Florian P. 
Published: January 2015

AbstractThe non‐heme iron enzyme EgtB catalyzes O2‐dependent CS bond formation between γ‐glutamyl cysteine and N‐α‐trimethyl histidine as the central step in ergothioneine biosynthesis. Both, the catalytic activity and the architecture of EgtB are distinct from known sulfur transferases or thiol dioxygenases. The crystal structure of EgtB from Mycobacterium thermoresistibile in complex with γ‐glutamyl cysteine and N‐α‐trimethyl histidine reveals that the two substrates and three histidine residues serve as ligands in an octahedral iron binding site. This active site geometry is consistent with a catalytic mechanism in which CS bond formation is initiated by an iron(III)‐complexed thiyl radical attacking the imidazole ring of N‐α‐trimethyl histidine.

ABSTRACTA novel aromatic diamine‐based benzoxazine monomer (PDETDA) was successfully prepared from diethyltoluenediamine (DETDA), phenol, and paraformaldehyde through a simple one‐step solvent‐less method. The structure of PDETDA was confirmed by FTIR, 1H NMR, and 13C NMR. The curing behavior of PDETDA was studied by DSC, FTIR, and rheological measurement. The results showed that the alkyl substituents on the benzene ring in DETDA not only facilitated the synthesis of PDETDA by effectively hindering the formation of triazine network, but also endowed PDETDA with the advantage of low viscosity (1 Pa s at 90°C). However, steric hindrance of the substituents made PDETDA difficult to form a crosslinked network through ring‐opening polymerization, and therefore only oligomers and noncrosslinked polymers were obtained. The curing kinetics of PDETDA was studied by nonisothermal DSC, and the results revealed that the curing of PDETDA displayed autocatalytic characteristic. © 2015 Wiley Periodicals, Inc. J. Appl.

Published: January 2015

AbstractHigh‐temperature chlorination of a fullerene C86 with VCl4 afforded non‐classical C84Cl30 and C82Cl30 containing one and two heptagons, respectively, in the carbon cages. Two types of C2 losses, which differ in the final arrangements of separate or fused pentagons, can occur successively in either order, producing rather flat or concave regions on the shrinked carbon cage. In the chlorination‐promoted skeletal transformation of C86 (isomer no. 16) with the loss(es) of C2 units, the structures of the starting, intermediate, and final compounds were all revealed unambiguously by X‐ray single crystal diffraction.

Published: January 2015

AbstractMicrobial fuel cell (MFC) is a novel technology that is able to convert the chemical energy of organic and inorganic substrates to electrical energy directly. The use of fossil fuels and recent energy crisis bring increasing attention to this technology. Besides electricity generation, wastewater treatment is another application of MFCs. Sulfide is a hazardous ion that is common in wastes. In this article, dual‐chamber MFC was fabricated and a mixed culture of microorganisms was used as an active biocatalyst in an anaerobic anodic chamber to convert substrate to electricity. The obtained experimental results indicate that this MFC can successfully alter sulfide to elementary sulfur and power generation. The initial concentration of sulfide in wastewater was 1.5 g L−1, and it was removed after 10 days of MFC operation. Maximum produced power and current density were 48.68 mW⋅m−2 and 231.47 mA⋅m−2, respectively. Besides, the influences of a biocathode were investigated and accordingly the data obtained for power and current density were increased to 372.27 mW⋅m−2 and 1,665.15 mA⋅m−2, respectively.

AbstractBackground and purposeBlood‐brain barrier disruption during the earliest phases of lesion formation in multiple sclerosis (MS) patients is commonly ascribed to perivenular inflammatory activity and is usually accompanied by increased diffusivity. Reduced diffusivity has also been shown in active lesions, albeit less frequently. This study aimed to characterize the development and natural history of contrast‐enhanced lesions by weekly following five relapsing remitting (RR) MS patients.Materials and methodsDiffusion tensor imaging (DTI), perfusion imaging, FLAIR and contrast‐enhanced 3D T1‐weighted MR, were weekly performed on five untreated patients recently diagnosed with RR MS.ResultsAll five patients showed significant increases of the apparent diffusion coefficient (ADC) in the lesions compared to the first time point. One of the five patients presented 98 active lesions on ADC maps among which 36 had a volume larger than 10 mm3. In two of these lesions, a 1 week transient decrease in ADC was detected at the time of the first gadolinium enhancement. Also, the perfusion analysis showed a concomitant increase in the relative cerebral blood volume.ConclusionsThe infrequency detection of such ADC decrease in a new lesion is probably due to its very short duration. This observation may be consistent with a hyper‐acute inflammatory stage concomitant with an increased reactional perfusion.

Published: January 2015

AbstractThe composition of the epicuticular leaf n‐alkanes of eight populations of three Satureja montana subspecies (S. montana L. subsp. pisidica (Wettst.) Šilić, S. montana L. subsp. montana, and S. montana L. subsp. variegata (Host) P. W. Ball), from central and western areas of the Balkan Peninsula was characterized by GC‐FID and GC/MS analyses. In the leaf waxes, 15 n‐alkane homologs with chain‐lengths ranging from C21 to C35 were identified. The main n‐alkane in almost all samples was n‐nonacosane (C29), but differences in the contents of three other dominant n‐alkanes allowed separating the coastal from the continental populations. The diversity and variability of the epicuticular‐leaf‐n‐alkane patterns and their relation to different geographic and bioclimatic parameters were analyzed by several statistical methods (principal component, discriminant, and cluster analyses as well as the Mantel test). All tests showed a high correlation between the leaf n‐alkane pattern and the geographical distribution of the investigated populations, confirming the differentiation between S. montana subsp. pisidica and the other two subspecies. The S. montana subsp. variegata and S. montana subsp. montana populations are geographically closer and their differentiation according to the leaf‐n‐alkane patterns was not clear, even though there was some indication of discrimination between them. Moreover, most of the bioclimatic parameters related to temperature were highly correlated with the differentiation of the coastal and the continental populations.
