BACKGROUNDThe exonic single‐nucleotide variant rs11762213 located in the MET oncogene has recently been identified as a prognostic marker in clear cell renal cell carcinoma (ccRCC). This finding was validated with The Cancer Genome Atlas (TCGA) cohort, and the biologic implications were explored.METHODSThe genotype status for rs11762213 was available for 272 patients. Paired tumor‐normal data, genomic data, and clinical information were acquired from ccRCC TCGA data sets. Cancer‐specific survival (CSS) was analyzed with the competing risk method, and Cox proportional hazards regression was used for the analysis of the time to recurrence (TTR). Multivariate competing risk models were fitted to adjust for the validated Mayo Clinic Stage, Size, Grade, and Necrosis (SSIGN) score.RESULTSThe variant allele of rs11762213 was detected in 10.3% of the cohort. After adjustments for the SSIGN score, the risk allele remained a significant predictor for adverse CSS (hazard ratio [HR], 3.88; 95% confidence interval [CI], 1.99‐7.56; P < .0001) and for TTR (OR, 2.97; 95% CI, 1.43‐6.2; P = .003). The mapping of rs11762213 to regulatory regions within the genome suggested that it might affect a DNA enhancer region. RNA and protein sequencing data for MET did not reveal differences in steady‐state expression with stratification by risk allele.CONCLUSIONSThe exonic MET variant rs11762213 is an independent predictor of adverse CSS and TTR in ccRCC and should be integrated into clinical practice for prognostic stratification. Genomic analysis suggests that the single‐nucleotide polymorphism may affect an enhancer region located in the coding region of MET. Further biological mechanistic interrogation is currently underway. Cancer 2016;122:402–410. © 2015 American Cancer Society.
Ultrafast Photoluminescence from the Core and the Shell in CdSe/CdS Dot‐in‐Rod Heterostructures
Authors: Diroll Benjamin T. , Turk Michael E. , Gogotsi Natalie , Murray Christopher B. , Kikkawa James M. 
Published: October 2015

AbstractWith an ultrafast time‐resolved photoluminescence system utilizing a Kerr gate, the time‐resolved photoluminescence of core and shell constituents within CdSe/CdS dot‐in‐rod heterostructures is studied as a function of heterostructure size. Measurements performed at low excitation fluence generating, on average, less than one exciton per nanorod, reveal photoluminescence from direct recombination of carriers in the CdS heterostructure rod with lifetime generally increasing from 0.4 ps to 1.3 ps as the rod length increases. Decay of the CdS rod photoluminescence is accompanied by an increase in emission from the CdSe core on comparable time scales, also trending towards larger values as the rod length increases. The observed kinetics can be explained without invoking a non‐radiative trapping mechanism. We also present alloying as a mechanism for enhancing electron confinement and reducing fluorescence lifetime at nanosecond time scales.
Synthesis of a Low‐Molecular‐Weight Fluorescent Ambidextrous Gelator: Development of Graphene‐ and Graphene‐Oxide‐Included Gel Nanocomposites
Authors: Mandal Subhra Kanti , Mandal Deep , Das Prasanta Kumar 
Published: October 2015

AbstractLow‐molecular‐weight fluorescent supramolecular ambidextrous gelators have drawn enormous attention owing to their ever‐increasing number of potential applications. In this study, we synthesized a low‐molecular‐weight fluorescent ambidextrous gelator consisting of hydrophobic pyrenebutyric acid moieties at the N termini of a central l‐lysine, and an ethyleneoxy unit coupled with 1‐(3‐aminopropyl)imidazole via a succinic acid linker as a hydrophilic moiety at the C terminus. This compound showed efficient hydrogelation and organogelation, having minimum gelation concentrations of 0.5 % (w/v) in a DMSO/water mixture (1:4 v/v) and 0.2 % (w/v) in nitrobenzene. The presence of the pyrene moieties in the structure rendered the ambidextrous gelator fluorescent. Significant amounts of both graphene oxide and reduced graphene oxide were included within these gels to form a stable soft nanohybrid. Hydrogen bonding, π–π stacking and van der Waals interactions are the key factors for self‐assembly leading to gelation. The complementary interactions between the π‐electronic surface of 2D graphene sheet and the aromatic pyrene moieties of the gelator play key roles in the inclusion of the nanomaterials into the gels. The inclusion of carbon nanomaterials within the gels resulted in a notable improvement in the stiffness of the soft nanocomposites compared to native gels. The native gels and soft nanocomposites have shear thinning properties and are thixotropic in nature.
Development and Validation of the Pride in Eating Pathology Scale (PEP‐S)

Published: October 2015

There is a growing body of theoretical and clinical literature highlighting the role of pride in maintaining eating disordered behaviours. Despite its clinical importance, there are no measures to assess feelings of pride associated with eating psychopathology. This study describes the development and validation of the Pride in Eating Pathology Scale (PEP‐S), a self‐report questionnaire that examines feelings of pride towards eating disordered symptoms (e.g., pride in food restriction, thinness and weight loss). Participants were 390 females, recruited from university and community populations, whose mean age was 26.99 years. Respondents rated pride in eating pathology on a 7‐point Likert‐scale. Principal Component Analysis indicated that the 60‐item scale comprised a four component structure: (1) pride in weight loss, food control and thinness, (2) pride in healthy weight and healthy eating, (3) pride in outperforming others and social recognition and (4) pride in capturing other people's attention due to extreme thinness. These four components explained a total of 65.31% of the variance. The PEP‐S demonstrated very good internal reliability (α ranging from 0.88 to 0.98) and very good test–retest reliability over a 3‐week time‐span (r ranging from 0.81 to 0.93). The PEP‐S also showed excellent convergent and discriminant validity. Furthermore, the scale discriminated between women with high and low levels of eating psychopathology. The PEP‐S is a psychometrically robust measure of pride in eating pathology. It has the potential to advance theoretical understanding and may also be clinically useful.

The PEP‐S is a valid, reliable, quick and easy to administer self‐report questionnaire that measures pride related to eating pathology.
The PEP‐S assesses four clinically relevant dimensions: (1) pride in weight loss, food control and thinness, (2) pride in healthy weight and healthy eating, (3) pride in outperforming others and social recognition and (4) pride in capturing other people's attention due to extreme thinness.
The PEP‐S has very good internal and test–retest reliability, and very good convergent and discriminant validity.
The PEP‐S distinguishes between women with higher and lower levels of eating psychopathology.
The PEP‐S makes an important contribution to understanding pride in eating psychopathology, which is essential from both clinical and theoretical perspectives.
Heart failure with normal ejection fraction is uncommon in acute myocardial infarction settings but associated with poor outcomes: a study of 91 360 patients admitted with index myocardial infarction between 1998 and 2010

Published: October 2015

AimData are scant on the incidence and prognosis of heart failure (HF) with normal ejection fraction (HFNEF, EF >49%) in an acute myocardial infarction (AMI) setting. The aim of this study was to examine incidence and predictors of HFNEF during an index acute myocardial infarction (AMI) and its subsequent associations with patient outcomes.Methods and resultsThis study analysed 91 360 patients with LVEF data from the SWEDEHEART registry on consecutive AMI patients between 1998 and 2010. Echocardiography or LV angiography was used to assess LVEF. In‐hospital HF diagnoses required presence of crackles, and use of i.v. diuretics or inotropic drugs during admission. Among HF patients, the proportion of HFNEF patients increased (from 18% to 31%) during the period. Incidence of HFNEF in the AMI population remained fairly unchanged (from 7.7% to 8.1%). In contrast, the proportion of HF patients with reduced EF (HFREF, EF ≤49%) declined (from 47% to 26%), as did the proportion of REF patients without HF (from 20% to 16%). AMI patients with NEF without HF increased (from 25% to 50%). HFREF and HFNEF patients showed considerably higher long‐term mortality compared with patients with no HF, irrespective of EF [the HFREF and HFNEF hazard ratio, compared with NEF, was 4.5 (4.4–4–6) and 3.3 (3.1–3.4), respectively, and 1.6 (1.5–1.65) for REF]. The adjusted HFNEF hazard ratio, compared with NEF, was 1.9 (1.8–2.0). Age, female gender, diabetes mellitus, hypertension, AF, and chronic kidney disease were strong predictors of HFNEF (P < 0.001).ConclusionThe proportion of AMI patients with HFNEF is constant over time. HFNEF patients have a considerably worse long‐term prognosis compared with patients without clinical HF, irrespective of EF.
Temporal variation of stable isotopes in a precipitation–groundwater system: implications for determining the mechanism of groundwater recharge in high mountain–hills of the Loess Plateau, China
Authors: Tan Hongbing , Wen Xiawei , Rao Wenbo , Bradd John , Huang Jinzhong 
Published: October 2015

AbstractThe groundwater in shallow loess aquifers in high mountain–hills in the western Loess Plateau in China is almost the sole water resource for local residents. However, the question about how the loess groundwater naturally circulates in these high mountain–hills, characterized by low precipitation and high potential evaporation, remains unclear. The objectives of this study are to evaluate the application of hydrogen and oxygen isotopes to (1) examine temporal variations of the isotopic composition of precipitation and shallow groundwater and (2) uncover the mechanism of groundwater recharge in high mountain–hills. Results from 2 years of monitoring data show a difference in the stable isotopes for groundwater and local precipitation between the winter and summer periods. Similar to precipitation, stable isotopes in groundwater are observed to be depleted in winter and enriched in summer, particularly in oxygen isotope. A prominent characteristic is that H and O isotopes of groundwater show a very clear response to strong precipitation in the rainy season in 2013. The results highlight that local precipitation is the likely recharge source for groundwater in shallow loess aquifers. Annual recharge from local precipitation maintains the groundwater resource in the shallower loess aquifer. The mechanisms governing shallow loess groundwater recharge in high mountain–hills were evaluated. In addition to possible vertical slow percolation of soil water through the unsaturated zone, rapid groundwater recharge mechanisms have been identified as temporal preferential infiltration through sinkholes, slip surface or landslide surface and through the interface of loess layer and palaeo‐soils. Most groundwater can be recharged after a heavy rainy season. Copyright © 2015 John Wiley & Sons, Ltd.

Published: October 2015

AbstractAimsThis study examines the intraperitoneal behavior of two cyanoacrylate tissue adhesives: Ifabond® and a new, non‐marketed octyl cyanoacrylate adhesive (OCA) used for the intraperitoneal fixation of a laminar expanded polytetrafluoroethylene (ePTFE) mesh. Material and Methods: In 36 New Zealand White rabbits, 3 × 3 cm (n = 24) or 1.5 × 3 cm (n = 12) fragments of ePTFE mesh (Preclude®, Gore, Flagstaff, USA) were fixed to the parietal peritoneum using OCA or Ifabond®. Peritoneal fluid was obtained at the time of implant and at 2 weeks postimplant for determination of the cytokines interleukin‐6 (IL‐6) and tumor necrosis factor alpha (TNF‐α). At 14 or 90 days postsurgery, the animals were euthanized and the meshes excised to assess host tissue incorporation, the macrophage response, apoptosis and fixation strength (T‐peel tensiometry). Results: Peritoneal fluid IL‐6 and TNF‐α concentrations were similar in the OCA and Ifabond® groups. Both adhesives gave rise to adequate mesothelialization of the laminar ePTFE. Macrophage counts were similar for the two study groups, but a significantly increase in macrophage response was observed from 14 to 90 days for Ifabond®. At 90 days postimplant, apoptotic cell counts was lower for the implants fixed with OCA and a fixation strength was significantly lower for OCA. Conclusions: Despite similar cytokine levels at 2 weeks and similar host tissue incorporation observed for the meshes fixed with the two adhesives, the use of Ifabond® gave rise to a greater apoptosis rate, although this adhesive provided a stronger fixation bond. © 2015 Wiley Periodicals, Inc.

Published: October 2015

AbstractA coloring of the edges of a graph G is strong if each color class is an induced matching of G. The strong chromatic index of G, denoted by , is the least number of colors in a strong edge coloring of G. Chang and Narayanan (J Graph Theory 73(2) (2013), 119–126) proved recently that for a 2‐degenerate graph G. They also conjectured that for any k‐degenerate graph G there is a linear bound , where c is an absolute constant. This conjecture is confirmed by the following three papers: in (G.

Let be the line graph of a graph G, and let be the square of the line graph . Then . We prove that if a graph G has an orientation with maximum out‐degree k, then has coloring number at most . If G is a k‐tree, then has coloring number at most . As a consequence, a graph with has , and a k‐tree G has .
A Reconfigurations Analogue of Brooks' Theorem and Its Consequences
Authors: Feghali Carl , Johnson Matthew , Paulusma Daniël 
Published: October 2015

AbstractLet G be a simple undirected connected graph on n vertices with maximum degree Δ. Brooks' Theorem states that G has a proper Δ‐coloring unless G is a complete graph, or a cycle with an odd number of vertices. To recolor G is to obtain a new proper coloring by changing the color of one vertex. We show an analogue of Brooks' Theorem by proving that from any k‐coloring, , a Δ‐coloring of G can be obtained by a sequence of recolorings using only the original k colors unless

G is a complete graph or a cycle with an odd number of vertices, or
, G is Δ‐regular and, for each vertex v in G, no two neighbors of v are colored alike.

We use this result to study the reconfiguration graph of the k‐colorings of G. The vertex set of is the set of all possible k‐colorings of G and two colorings are adjacent if they differ on exactly one vertex. We prove that for , consists of isolated vertices and at most one further component that has diameter . This result enables us to complete both a structural and an algorithmic characterization for reconfigurations of colorings of graphs of bounded maximum degree.
