Suicidality in adolescents and adults with binge‐eating disorder: Results from the national comorbidity survey replication and adolescent supplement
Authors: Forrest Lauren N. , Zuromski Kelly L. , Dodd Dorian R. , Smith April R. 
Published: July 2016

ABSTRACTObjectiveThe relation between binge‐eating disorder (BED) and suicidality (i.e., suicide ideation, plan, and/or attempt) has not been studied extensively, and it is unknown whether BED is uniquely associated with suicidality when adjusting for comorbid psychopathology. Moreover, the course of suicidality in BED has not been determined and it is unknown whether BED precedes suicidality or vice versa.MethodA total of 10,123 adolescents and 2,980 adults from two nationally representative surveys were administered diagnostic interviews assessing psychopathology and suicidality, as well the retrospectively reported ages of onset.ResultsAmong adults and adolescents, BED was associated with elevated odds of suicide ideation, plan, and attempt at a univariate level, but BED was not associated with elevated odds of suicidality when adjusting for comorbid psychopathology. Kaplan–Meier estimates of temporal patterns displayed that most adolescents experienced suicidality onset following BED onset, whereas most adults experienced suicidality onset prior to BED onset.DiscussionBED, comorbid disorders, and suicidality share common factors and interrelations, and individuals with BED and comorbid disorders may be at particularly high risk for suicidal outcomes. The presence of BED in adolescence may serve as a marker for more severe symptomatology that precedes the occurrence of suicidality. Research is needed to understand how eating disorder symptoms, comorbid symptoms, and suicidality affect one another over time. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2017; 50:40–49)

AbstractThe red alga Polysiphonia morrowii, native to the North Pacific (Northeast Asia), has recently been reported worldwide. To determine the origin of the French and Argentine populations of this introduced species, we compared samples from these two areas with samples collected in Korea and at Hakodate, Japan, the type locality of the species. Combined analyses of chloroplastic (rbcL) and mitochondrial (cox1) DNA revealed that the French and Argentine populations are closely related and differ substantially from the Korean and Japanese populations. The genetic structure of P. morrowii populations from South Atlantic and North Atlantic, which showed high haplotype diversity compared with populations from the North Pacific, suggested the occurrence of multiple introduction events from areas outside of the so‐called native regions. Although similar, the French and Argentine populations are not genetically identical. Thus, the genetic structure of these two introduced areas may have been modified by cryptic and recurrent introduction events directly from Asia or from other introduced areas that act as introduction relays. In addition, the large number of private cytoplasmic types identified in the two introduced regions strongly suggests that local populations of P. morrowii existed before the recent detection of these invasions. Our results suggest that the most likely scenario is that the source population(s) of the French and Argentine populations was not located only in the North Pacific and/or that P. morrowii is a cryptogenic species.
C‐Glycosides, Array‐based Addressable Libraries, and the Versatility of Constant Current Electrochemistry
Authors: Smith Jake A. , Xu Guoxi , Feng Ruozhu , Janetka James W. , Moeller Kevin D. 
Published: July 2016

AbstractConstant current electrochemical reactions are very versatile tools for conducting oxidation and reduction reactions. In the reactions, the potential at the working electrode automatically adjusts to that of the substrate in solution, a situation that allows for the same overall synthetic approach to be used for both the direct oxidation and reduction of substrates and the generation of a wide range of chemical reagents and catalysts. The science presented in this manuscript illustrates how a combination of these methods can be used to create new opportunities for synthesis. Specifically, a direct constant current electrolysis was used to synthesize C‐glycoside derivatives that were then placed site‐selectively on a microelectrode array by using the same overall electrochemical approach to generate chemical reagents.

Published: July 2016

AbstractBackgroundOral cavity cancer is one of the most common head and neck cancers in the world. The purpose of this study was to determine the incidence and risk factors for stroke after surgery in patients with oral cavity cancer with a focus on the effect of neck dissection.MethodsData from the Taiwan National Health Insurance Research Database for newly diagnosed oral cavity cancer between January 1, 2005, and December 31, 2007, were included.ResultsNeck dissection did not increase the risk of stroke after treatment. Patients with ages older than 44 years, hypertension, diabetes mellitus, coronary artery disease, previous stroke, or postoperative chemoradiotherapy had a significantly higher risk of stroke (p < .05).ConclusionOur data demonstrate that neck dissection does not increase the risk of stroke in patients with oral cavity cancer. Patients have higher risk of stroke after cancer treatment because of their older age, specific comorbidities, and/or type of postoperative treatment. © 2016 Wiley Periodicals, Inc.

Published: July 2016

AbstractBackgroundThe purpose of this study was to determine the rate of contralateral neck recurrence after surgery and unilateral neck radiotherapy, for lateralized tonsillar cancers with ipsilateral neck disease, in order to inform future clinical trial protocols for this disease.MethodsPatients with lateralized tonsillar squamous carcinoma (T1–T2, N0–N2b), treated with surgery and unilateral adjuvant radiotherapy in a single United Kingdom center were retrospectively identified. Rates of recurrence in the contralateral, unirradiated neck were analyzed, together with survival and toxicity data.ResultsOf 81 patients included, after a median follow‐up of 5.7 years, no contralateral recurrences were identified. Five‐year overall survival, progression‐free survival, and locoregional control were 91.0%, 93.0%, and 95.4%, respectively.ConclusionUnilateral radiotherapy is an effective and safe treatment option for the postoperative management of lateralized tonsillar cancers, even in patients with N2b disease, and should be recommended in future clinical trial protocols. © 2016 Wiley Periodicals, Inc.

Published: July 2016

AbstractCurrent treatments in hypoplastic left heart syndrome (HLHS) include multiple surgeries to refunctionalize the right ventricle and/or transplant. The development of a tissue‐engineered left ventricle (LV) would provide a therapeutic option to overcome the inefficiencies and limitations associated with current treatment options. This study provides a foundation for the development and fabrication of the bioengineered open ventricle (BEOV) model. BEOV molds were developed to emulate the human LV geometry; molds were used to produce chitosan scaffolds. BEOV were fabricated by culturing 30 million rat neonatal cardiac cells on the chitosan scaffold. The model demonstrated 57% cell retention following 4days culture. The average biopotential output for the model was 1615 µV. Histological assessment displayed the presence of localized cell clusters, with intercellular and cell‐scaffold interactions. The BEOV provides a novel foundation for the development of a 3D bioengineered LV for application in HLHS. © 2016 Wiley Periodicals, Inc.

ABSTRACTSnow cover extent, duration, and properties were simulated (1979/1980–2013/2014) for the Rio Olivares Basin (548 km2) in central Chilean Andes, in an effort to understand conditions and trends (linear) at a basin scale. The National Aeronautics and Space Administration Modern‐Era Retrospective Analysis for Research and Applications products, together with the snow modelling software package SnowModel allowed simulations of first‐order atmospheric forcings (mean annual air temperature (MAAT) and water‐equivalent precipitation) and terrestrial snow features (snow cover extent, duration, snow water‐equivalent depth, snow density, and runoff generated from snow melt). Simulated snow cover extent and depletion curves were verified against Moderate Resolution Imaging Spectroradiometer‐derived snow cover data. For the Rio Olivares Basin, MAAT was −2.9 ± 0.6 °C with a mean 0° isotherm at 3325 m a.s.l. The greatest temporal and spatial changes in temperature over the 35‐year period occurred in January and at the highest elevations, respectively. Mean annual precipitation was 1.86 ± 0.60 m w.e., indicating an increase in precipitation of ∼0.1 m w.e. 100 m−1 increase in elevation. On average, ∼90% of the basin precipitation fell as snow, varying from 70% at ∼2600 m a.s.l., to 95% at ∼4200 m a.s.l. In 20 out of 35 years the snow cover extent went to 0% (no basin snow cover) by end‐of‐summer (during March), and the snow duration increased on average by ∼10 days 100 m−1 increase in elevation. Approximately 85% of the basin outlet freshwater runoff originated from snowmelt, making snowmelt a dominant contributor to water resources. Snowmelt‐derived basin runoff was dominated by variability in snow precipitation rather than by variability in MAAT.

Published: July 2016

AbstractBACKGROUNDGac fruit (Momordica cochinchinensis Spreng.) is a rich source of carotenoids for the manufacture of powder, oil and capsules for food, cosmetic and pharmaceutical uses. Currently, only the aril of the Gac fruit is processed and the peel, similar to the other components, is discarded, although it contains high level of carotenoids, which could be extracted for commercial use. In the present study, four different drying methods (hot‐air, vacuum, heat pump and freeze drying), different temperatures and drying times were investigated for producing dried Gac peel suitable for carotenoid extraction.RESULTSThe drying methods and drying temperatures significantly affected the drying time, carotenoid content and antioxidant capacity of the dried Gac peel. Among the investigated drying methods, hot‐air drying at 80 oC and vacuum drying at 50 oC produced dried Gac peel that exhibited the highest retention of carotenoids and the strongest antioxidant capacity.CONCLUSIONHot‐air drying at 80 oC and vacuum drying at 50 oC are recommended for the drying of Gac peel. © 2016 Society of Chemical Industry
Hydrolytic Cleavage of Paraoxon by Octanohydroxamate Ion in Cationic Microemulsions
Authors: Satnami Manmohan L. , Dewangan Hitesh K. , Nagwanshi Rekha 
Published: July 2016

ABSTRACTThe hydrolysis reaction of O,O‐diethyl O‐p‐nitrophenylphosphate (Paraoxon) with the octanohydroxamate ion (OHA−) was studied in a cationic oil‐in‐water (O/W) microemulsion system over a pH range 7.5–12.0 at 300 K. The O/W systems are stabilized by using cationic surfactant, cetyltrimethylammonium bromide (CTAB), and n‐butanol as cosurfactants. In a microemulsion, the rate enhancement by OHA− is greater toward the cleavage of paraoxon than its spontaneous (2.1 × 107 s−1) hydrolysis. The kobs values for the reaction of paraoxon with OHA− were determined in different microemulsion compositions with varying chain length of alcohols (n‐butanol, n‐pentanol, n‐octanol, and n‐dodecanol) and alkanes (n‐hexane, n‐heptane, and n‐decane). The effects of water content, pH, and size of the oil pool have been discussed.

ObjectivesTo evaluate the sites of nodal failure (NF) of nasopharyngeal carcinoma (NPC) treated with intensity‐modulated radiation therapy (IMRT).Study DesignRetrospective chart review.MethodsWe reviewed the records of 165 patients with nonmetastatic NPC treated with IMRT between July 1998 and April 2011 at our institution. Recurrent nodes were delineated on imaging and coregistered with the original treatment planning computed tomography. Failures were assessed as in‐field, out‐field, or marginal based on the relative volumes of the recurrent nodes covered by the original dose distribution.ResultsTen patients had NF at a median follow‐up of 70.4 months for surviving patients. The 3‐ and 5‐year overall survival and NF rates were 88.7%, 76.0% and 5.8%, 7.7%, respectively. Six of the nodal failures were in‐field, of which five occurred in level II; whereas four had out‐field failures, all of which were in the protected parotid gland area. There were no recurrences in level 1b despite this region being protected. The cumulative 3‐ and 5‐year failure rates in the parotid gland area were 2.2% and 3.1%, respectively. Three patients with parotid failure initially had subcentimeter, nonspecific nodules in the same locations of the parotid gland as the recurrent nodes.ConclusionNodal failure is uncommon after IMRT in NPC. Recurrence in the parotid gland region accounts for all of the out‐field failures and 40% of NF in our study. Comprehensive assessment of nodules in or around the parotid gland is therefore a key aspect of treatment planning and follow‐up.Level of Evidence4. Laryngoscope, 2016 127:377–382, 2017

Published: July 2016

AbstractA material for both magnetic coupling and electrocatalytic hydrogen evolution based on the copper complex, [(L)2Cu2] is formed by the reaction of CuCl2·2H2O with the tetradentate ligand 6‐(3‐aminomethylpropanol)‐2‐tert‐buty‐4‐methylphenol (H2L), which is prepared by reaction of 2‐tert‐butyl‐4‐methylphenol, 3‐amino‐1‐propanol, and formaldehyde. Structural studies show that in the solid state complex 1 exhibits strong antiferromagnetic exchange interaction between copper(II) ions mediated by oxygen‐bridges. In liquid, 1 becomes a monomer, and can electrocatalyze hydrogen generation both from acetic acid with a turnover frequency (TOF) of 101.70 mol of hydrogen per mole of catalyst per hour at an overpotential (OP) of 941.6 mV (in DMF), and a natural buffer with a TOF of 650 mol of hydrogen per mole of catalyst per hour at an OP of 836.7 mV.
Floating‐leaved macrophyte (Trapa japonica) drastically changes seasonal dynamics of a temperate lake ecosystem

Published: July 2016

AbstractWater chestnut (genus Trapa) is an annual floating‐leaved macrophyte that produces dense beds known to drastically modify freshwater ecosystems. Although Trapa displays a distinct phenology that should alter the innate seasonal dynamics of ecosystems, the seasonality of these effects has rarely been investigated. Therefore, we examined seasonal changes in physicochemical conditions and assemblages of zoobenthos and zooplankton, and whether these changes were correlated with the rise and decline of dense beds of Trapa japonica in Lake Mikata, a temperate shallow lake in central Japan. Our results suggested that the formation of dense Trapa beds during summer resulted in hypoxia, which significantly decreased the abundance of Chironomidae and Oligochaeta in the benthic community, as well as that of Calanoida among zooplankton. When dense Trapa beds formed, we also detected growth of other taxa that were resistant to hypoxia, including Cladocera, Cyclopoida, Ostracoda, and Nematoda. Chlorophyll a concentration declined across the lake during summer, when dense Trapa beds formed. The decline in Trapa beds from autumn to spring resulted in increased dissolved oxygen concentration, chlorophyll a concentration, and invertebrate abundance (Chironomidae, Oligochaeta and Calanoida), as well as a decrease in taxa utilizing the dense Trapa beds. Our results suggest that the phenology of dense Trapa beds can drastically change the seasonal dynamics of physicochemical conditions and the lower components of the food web in a shallow lake ecosystem.
Fabrication characteristics and tribological behavior of Al/SiC/Gr hybrid aluminum matrix composites: A review
Authors: Singh Jaswinder 
Published: July 2016

Abstract
Improvement in surface properties and retainment of bulk properties are essential requirements for the design of components for wear resistance applications. This paper summarizes various features of Al/SiC/Gr hybrid composites that can be employed in different tribological applications. The study has revealed that the processing route plays a significant role in obtaining a homogeneous structure of these composites. In powder metallurgy, the selection of sizes of the matrix and reinforcement powders is crucial, whereas the wettability between the reinforcement particles and molten alloy is a major challenge in liquid metallurgy. The incorporation of SiC particles increases the mechanical strength and wear performance of Al composites. However, ejection of these particles can reduce the wear performance of Al composites under severe conditions. The addition of Gr particles helps in the formation of a thick and extensive tribolayer on the wear surface. This layer reduces direct contact between the rubbing surfaces, thereby decreasing the wear rate under certain conditions. Morphological analysis of worn surfaces has confirmed that the hybrid composites exhibit superior wear properties than the pure Al alloy and the ceramic-reinforced composite. However, increase in the Gr content beyond a limiting value can deteriorate the tribological properties of these composites. Therefore, true optimization of a tribosystem (of the hybrid composite and counterface) can be achieved by selecting appropriate reinforcement contents.
Berlin Radiocarbon Measurements II

This date list covers age measurements carried out at the Radiocarbon Dating Laboratory of the German Academy of Sciences of Berlin (DAW) since 1963 and is a continuation of our first date list (Berlin I). Procedures and methods of preparing the samples are essentially the same. We completed our laboratory with a second electronic counting apparatus. Two further proportional counters with internal anticoincidence (Houtermann-Oeschger counters) are made from an old railway-car axle. The total volume of these counters is 4 L, the effective volume 2.2 L, the background 2.0 counts/min at 700 Torr (acetylene filling), and the contemporary standard value (0.95 NBS oxalic acid) is 20 counts/min. Each sample is measured twice, first for 48 hr and after 8 days for another 24 hr. Data have been calculated on the basis of a C14 half-life of 5570 yr (Godwin, 1962). Errors listed include the standard deviations (1σ) of the counting rates of the contemporary samples, the background and the unknown samples. Calculated errors less than 100 yr have been increased to that figure as a minimum.Corrections have not been made for C13 content. Mass spectrometrics C13 measurements of some samples indicate that errors resulting from fractionation are minimal.

Possible Depletion in 14C in Trees Growing in Calcareous Soils
Authors: Tauber Henrik 
Published: July 2016

14C activities of decadal samples from beech trees growing under extreme calcareous conditions were compared to 14C activities of decadal samples of the same age from a beech tree growing in a normal mold soil in order to see whether part of the carbon assimilated during photosynthesis might originate from 14C-deficient carbonates in the soil. The calcareous soils contained from 18 to 52% calcium carbonate, and this carbonate had a mean 14C age of 10,200 to 17,600 years BP. A comparison was also made with the 14C activity of contemporaneous samples from Douglas Fir from the US North Pacific (Stuiver, 1982).No significant depletion in 14C activity in beech trees growing in the highly calcareous soils was detected. The measured mean difference in 14C activity in beech trees from calcareous and non-calcareous sites corresponds to an uptake of 0.12 ± 0.3% carbon from soil carbonates in the calcareous sites.
