Authors: Kotiloğlu Selin Özkan , Çelik Sibel , Tanış Emine , Kurban Mustafa 
Published: June 2018

AbstractBisphenol A (BPA) is a chemical used in a variety of materials and has adverse effects on endocrine system. The substitutes of BPA have been developed to produce BPA‐free plastics. Fluorene‐9‐bisphenol (BPFL), has anti‐oestrogenic effects, is one of those substitutes used in ‘BPA‐free’ bottles. In this study, the physical, electronic and vibrational properties of BPFL molecule are investigated using density functional theory (DFT) calculations at B3LYP/6‐311G (d, p) basis set. Bond distances, Fourier transform infrared (FT‐IR) spectra, natural atomic charges, solvation energies, dipole moments and vibrational frequencies were carried out. The calculated bond distance for the optimized geometry of BPFL obtained from DFT calculations were compared with the measured results. Structural properties like radial distribution function (RDF) and probability distribution depending on coordination number have been calculated for the molecule. Ultraviolet–visible (UV‐Vis) spectra characteristics and the electronic features, such as absorption wavelengths, frontier orbitals, excitation energies and band gap energy of BPFL were also recorded using time‐dependent (TD) DFT approach based on optimized structure with different solvent environments. Finally, we investigated the effects of solvents on structural, electronic and vibrational frequencies of BPFL molecule.
Synthesis of CuxS Thin Films with Tunable Localized Surface Plasmon Resonances
Authors: Kalanur Shankara S , Seo Hyungtak 
Published: June 2018

AbstractIn this work, we report the fabrication of copper sulfide (CuS, Cu1.39S, and Cu2S) thin films with tunable localized surface plasmon resonance (LSPR). The thin films were synthesized by keeping the Cu precursor concentration constant and varying that of sodium thiosulfate, which dictated the final CuxS product. CuS showed the highest intensity LSPR peak and its intensity decreased with the increasing incorporation of Cu, as in the case of Cu1.39S, and vanished for the Cu‐rich Cu2S, indicating carrier concentration‐dependent plasmonic absorption. The shift in the XRD peak positions towards a lower degree and the increase in the d‐spacing values for CuS indicated the intercalation of Cu species in the initial covellite lattice, yielding Cu1.39S and Cu2S in the process. XPS valence band edge studies revealed that among the synthesized CuxS thin films, CuS showed a stronger p‐type as compared to Cu1.39S and Cu2S.

AbstractDeveloping eco‐friendly, high‐efficiency and cost‐effective catalysts for oxygen reduction reaction are significantly crucial for the application of direct‐methanol fuel cells. The metal‐free sulfur/nitrogen in‐situ co‐doped carbon nanosheets are prepared through polymerization process and carbonization process using aniline as a nitrogen source, 4‐aminobenzenesulfonamide as a sulfur source and NaCl as a template and protective layer. The obtained catalysts show the obvious two dimensional nanosheet structure with successful doping of S and N. Benefiting from high contents of S atoms and N atom, high special surface area and graphitic degree, well‐ordered micropores and synergetic interaction between thiophenic‐S, pyridinic N and graphitic N, the optimal catalyst S3/N‐CNS800 shows excellent oxygen reduction performance with 13.2 mV more positive half‐wave potential than that of 20% Pt/C, superior long‐term durability and tolerance to methanol crossover.

Authors: Lin Junqi , Han Qing , Ding Yong 
Published: June 2018

AbstractExploration of water oxidation catalyst (WOC) with excellent performance is the key for the overall water splitting reaction, which is a feasible strategy to convert solar energy to chemical energy. Although some compounds composed of noble metals, mainly Ru and Ir, have been reported to catalyze water oxidation with high efficiency, catalysts based on low‐cost and earth‐abundant transition metals are essential for realizing economical and large‐scale light‐driven water splitting. Various WOCs containing earth‐abundant metals (mainly Mn, Fe, Co, Ni, Cu) have been utilized for visible light‐driven water oxidation in recent years. In this Personal Account, we summarize our recent developments in WOCs based on earth‐abundant transition metals including polyoxometalates (POMs), metal oxides or bimetal oxides, and metal complexes containing multidentate ligand scaffolds for visible light‐driven water oxidation reaction.

AbstractBackgroundThere are only limited data on the failure patterns after surgical resection for duodenal cancer, and the role of adjuvant chemoradiotherapy (CRT) also remains controversial. In this study, the treatment outcomes of surgery alone were compared to those of surgery plus adjuvant CRT for duodenal cancer.MethodsBetween January 1991 and February 2013, a total of 47 patients with duodenal cancer had pancreaticoduodenectomy, and their age ranged from 31 to 80 (median 62). Twenty‐five patients (53%) underwent surgery alone, while 22 (47%) underwent surgery plus adjuvant CRT. Postoperative radiotherapy with concomitant 5‐fluorouracil was given to tumor bed and regional lymph nodes up to 40–55.4 Gy. Median duration of follow‐up was 31 months (range 6–286) for all patients and 90 months (range 14–286) for survivors.ResultsCRT (+) group included more patients with advanced nodal stage and overall stage group (p = 0.003 and 0.002, respectively). The 5‐year overall survival rates were not different between CRT (−) and CRT (+) groups (50.1 vs. 46.7%, p = 0.794). CRT (+) group achieved a superior 5‐year loco‐regional relapse‐free survival rate compared with CRT (−) group, but the difference did not reach a statistical significance (80.1 vs. 68.4%, p = 0.267). On multivariate analysis, however, the addition of CRT was the only favorable prognosticator predicting loco‐regional relapse‐free survival (p = 0.046). Two patients experienced grade 3 neutropenia during CRT.ConclusionsAdjuvant CRT after pancreaticoduodenectomy was correlated with an improved loco‐regional control in duodenal cancer. Considering the high loco‐regional recurrence in surgery alone group, CRT may be considered as adjuvant treatment.
Lipids and synaptic functions
Authors: Mochel Fanny 
Published: June 2018

AbstractSynaptic functions have long been thought to be driven by proteins, especially the SNARE complex, contrasting with a relatively passive role for lipids constituting cell membranes. It is now clear that not only lipids, i.e. glycerophospholipids, sphingolipids and sterols, play a determinant role in the dynamics of synaptic membranes but they also actively contribute to the endocytosis and exocytosis of synaptic vesicles in conjunction with synaptic proteins. On the other hand, a growing number of inborn errors of metabolism affecting the nervous system have been related to defects in the synthesis and remodelling of fatty acids, phospholipids and sphingolipids. Alterations of the metabolism of these lipids would be expected to affect the dynamics of synaptic membranes and synaptic vesicles. Still, only few examples are currently documented. It remains to be determined to which extent the pathophysiology of disorders of complex lipids biosynthesis and remodelling share common pathogenic mechanisms with the more traditional synaptopathies.
Polycystic kidney features of the renal pathology in glycogen storage disease type I: possible evolution to renal neoplasia

Published: June 2018

AbstractGlycogen storage disease type I (GSDI) is a rare genetic pathology characterized by glucose‐6 phosphatase (G6Pase) deficiency, translating in hypoglycemia during short fasts. Besides metabolic perturbations, GSDI patients develop long‐term complications, especially chronic kidney disease (CKD). In GSDI patients, CKD is characterized by an accumulation of glycogen and lipids in kidneys, leading to a gradual decline in renal function. At a molecular level, the activation of the renin‐angiotensin system is responsible for the development of renal fibrosis, eventually leading to renal failure. The same CKD phenotype was observed in a mouse model with a kidney‐specific G6Pase deficiency (K.G6pc−/− mice). Furthermore, GSDI patients and mice develop frequently renal cysts at late stages of the nephropathy, classifying GSDI as a potential polycystic kidney disease (PKD). PKDs are genetic disorders characterized by multiple renal cyst formation, frequently caused by the loss of expression of polycystic kidney genes, such as PKD1/2 and PKHD1. Interestingly, these genes are deregulated in K.G6pc−/− kidneys, suggesting their possible role in GSDI cystogenesis. Finally, renal cysts are known to predispose to renal malignancy development. In addition, HNF1B loss is a malignancy prediction factor. Interestingly, Hnf1b expression was decreased in K.G6pc−/− kidneys. While a single case of renal cancer has been reported in a GSDI patient, a clear cell renal carcinoma was recently observed in one K.G6pc−/− mouse (out of 36 studied mice) at a later stage of the disease. This finding highlights the need to further analyze renal cyst development in GSDI patients in order to evaluate the possible associated risk of carcinogenesis, even if the risk might be limited.
Ammopemphix hemisphaericus sp. nov., a new attached agglutinated foraminifer from the Pleistocene of the Arctic Ocean, and the taxonomic status of the genus Ammopemphix Loeblich, 1952
Authors: Waśkowska Anna , Kaminski Michael A. 
Published: June 2018

AbstractThe new speciesAmmopemphix hemisphaericussp. nov. is described from Pleistocene sediments of the Central Arctic Ocean. The species is a finely agglutinated monothalamous form with hemispherical shape and a terminal aperture located at the top of the test, often occurring in pseudocolonies.A. hemisphaericussp. nov. attaches itself to inorganic or organic substrates, often growing attached to the inside surfaces of calcareous or agglutinated foraminiferal tests. Pseudocolonies ofA. hemisphaericussp. nov. may also attach themselves to previous generations ofAmmopemphixindividuals. Based on our study of numerous specimens ofAmmopemphixfrom the Central Arctic Ocean, we propose modifications to the description of the genus. The genus may be pseudocolonial or consist of isolated individuals, and in the case of pseudocolonial forms, individual specimens may be arranged randomly or symmetrically. The genusAmmopemphixis found mostly in polar regions, and is here reported for the first time from the fossil record.

AbstractBackground:Depression is an important risk factor for suicide. However, other dimensions may contribute to the suicidal risk and to the transition from ideas to acts. We aimed to test the relative involvement of hopelessness, temperament, childhood trauma, and aggression in suicide risk in a large sample of patients with mood disorders.Methods:We assessed 306 patients with major depressive and bipolar disorders for clinical characteristics including hopelessness, temperament, childhood trauma, and aggression. We tested their associations with suicidal ideation and acts using standard univariate/bivariate methods, followed by multivariate logistic regression models.Results:In multivariate analyses, the loss of expectations subscore of the hopelessness scale was associated with lifetime suicidal ideation but not suicide attempt. Childhood emotional abuse, severity of current depression, and female gender were associated with lifetime suicide attempts, whereas hyperthymic temperament was protective. Only hyperthymic temperament differentiated patients with a history of suicidal ideas vs. those with a history of suicide attempt.Conclusions:Findings support the association of hopelessness with suicidal ideation and point to considering in suicidal acts not only depression, but also childhood emotional abuse, hyperthymic temperament, and gender.

Published: June 2018

Abstract
Peripherally inserted central catheter use has increased dramatically over the past decade, parallel to health care costs. Traditional bedside peripherally inserted central catheter placement requires anthropometric measurements of estimated catheter length and confirmation of appropriate tip positioning via chest radiograph. Newer bedside technology, using magnet and electrocardiogram capabilities, seeks to replace the traditional method with equal efficacy but less overall cost. The need for follow-up chest radiograph can been removed, a significant cost savings in direct patient care. In this retrospective case control study, we examine costs related to these 2 tip confirmation methods while assessing overall cost savings to the health care industry.
Middlemen, Colonial Officials, and Corruption: The rise and fall of government compradors in Hong Kong, 1840s–1850s
Authors: ABE KAORI 
Published: June 2018

AbstractExploring the rise and fall of government compradors, this article highlights Sino-British collusion in the corruption and extortion cases of the Hong Kong colonial government in the 1840s and the 1850s. A number of compradors worked for the Hong Kong colonial government throughout the nineteenth century, acting as a key communication channel between Chinese residents and colonial officials in the formative years of the colony. Various institutions of the colonial government, for instance the Colonial Treasury, Post Office, and British military, employed compradors. Colonial officials also personally employed compradors, who supported their principals’ work in the government. However, a symbiotic relationship between corrupt colonial officials and compradors had become a public problem by the mid-1850s. The colonial government responded to this by diversifying its Chinese staff rather than depending on monopolistic compradors, and also launched a scheme to nurture and employ British personnel who could act as intermediaries between the British and Chinese communities. At the same time, different kinds of Chinese intermediary elites emerged in Hong Kong from the 1860s onwards, and government compradors’ monopolistic authority in mediating between colonial officials and the Chinese public gradually declined. The volatile government comprador system highlights a key phase in the history of the evolution of the comprador system in Hong Kong.
RECONSTRUCTION OF EXPORT SERIES FOR PERU BEFORE THE GREAT DEPRESSION
Authors: Zegarra Luis Felipe 
Published: June 2018

AbstractThis article discusses the available sources of information on the value and volume of Peru’s exports and estimates the current value of exports, the index of export prices and the quantum of exports using a wide variety of sources. By relying on several sources, I estimate the first complete series of the current value of exports for Peru for 1830-1930. Importantly, I adjust other studies’ estimates by taking into account the deficiencies of foreign sources and by distinguishing between exports of specie and of minerals. The estimations show that exports experienced substantial growth in the 1850s and 1860s, during the Guano Era. Exports stagnated in the 1870s and dropped during the War of the Pacific (1879-1883) before recovering in the late 19thand early 20thcenturies, especially during World War I.
Growth in syntactic complexity between four years and adulthood: evidence from a narrative task
Authors: FRIZELLE Pauline , THOMPSON Paul A. , MCDONALD David , BISHOP Dorothy V. M. 
Published: June 2018

AbstractStudies examining productive syntax have used varying elicitation methods and have tended to focus on either young children or adolescents/adults, so we lack an account of syntactic development throughout middle childhood. We describe here the results of an analysis of clause complexity in narratives produced by 354 speakers aged from four years to adulthood using the Expressive, Receptive, and Recall of Narrative Instrument (ERRNI). We show that the number of clauses per utterance increased steadily through this age range. However, the distribution of clause types depended on which of two stories was narrated, even though both stories were designed to have a similar story structure. In addition, clausal complexity was remarkably similar regardless of whether the speaker described a narrative from pictures, or whether the same narrative was recalled from memory. Finally, our findings with the youngest children showed that the task of generating a narrative from pictures may underestimate syntactic competence in those aged below five years.
Food Production Standards and the Chinese Local State: Exploring New Patterns of Environmental Governance in the Bamboo Shoot Industry in Lin'an
Authors: Chan Kin Wing (Ray) , Flynn Andrew 
Published: June 2018

AbstractAlthough current studies into Chinese food supply and quality provide explanations for the causality of food problems, there is limited inquiry into the role of the county government. This is a serious omission for two main reasons: first, because county governments perform a key role in providing support for farmers through agricultural extension services and farmers’ cooperatives, and second, because county-level administrative divisions are central to developing novel instruments to manage supply chain relationships, such as food production standards. We investigate the key players involved in standard making and delivery at the county level. We also analyse how and why the county government engages in standard-setting activities. We use Lin'an's bamboo shoot production industry as a case study to understand how the local state implements “hazard-free,” “green” and “forest food” production standards. The paper concludes that traditional conceptualizations of the local state do not sufficiently address how nature, knowledge of standards and state authority co-produce institutional capacity to control food supply and quality in China. In practice, the local state engages with non-state actors to achieve superficial environmental efforts, such as developing food production standards to throw a “green cloak” over a productivist model.
Autochthonous spread of DENV-3 genotype III in Malaysia mitigated by pre-existing homotypic and heterotypic immunity

Published: June 2018

AbstractDengue virus type 3 genotype III (DENV-3/III) is widely distributed in most dengue-endemic regions. It emerged in Malaysia in 2008 and autochthonously spread in the midst of endemic DENV-3/I circulation. The spread, however, was limited and the virus did not cause any major outbreak. Spatiotemporal distribution study of DENV-3 over the period between 2005 and 2011 revealed that dengue cases involving DENV-3/III occurred mostly in areas without pre-existing circulating DENV-3. Neutralisation assays performed using sera of patients with the respective infection showed that the DENV-3/III viruses can be effectively neutralised by sera of patients with DENV-3 infection (50% foci reduction neutralisation titres (FRNT50) > 1300). Sera of patients with DENV-1 infection (FRNT50⩾ 190), but not sera of patients with DENV-2 infection (FRNT50⩽ 50), were also able to neutralise the virus. These findings highlight the possibility that the pre-existing homotypic DENV-3 and the cross-reacting heterotypic DENV-1 antibody responses could play a role in mitigating a major outbreak involving DENV-3/III in the Klang Valley, Malaysia.

AbstractAlthough measles incidence has reached historic lows in many parts of the world, the disease still causes substantial morbidity globally. Even where control programs have succeeded in driving measles locally extinct, unless vaccination coverage is maintained at extremely high levels, susceptible numbers may increase sufficiently to spark large outbreaks. Human mobility will drive potentially infectious contacts and interact with the landscape of susceptibility to determine the pattern of measles outbreaks. These interactions have proved difficult to characterise empirically. We explore the degree to which new sources of data combined with existing public health data can be used to evaluate the landscape of immunity and the role of spatial movement for measles introductions by retrospectively evaluating our ability to predict measles outbreaks in vaccinated populations. Using inferred spatial patterns of accumulation of susceptible individuals and travel data, we predicted the timing of epidemics in each district of Pakistan during a large measles outbreak in 2012–2013 with over 30 000 reported cases. We combined these data with mobility data extracted from over 40 million mobile phone subscribers during the same time frame in the country to quantify the role of connectivity in the spread of measles. We investigate how different approaches could contribute to targeting vaccination efforts to reach districts before outbreaks started. While some prediction was possible, accuracy was low and we discuss key uncertainties linked to existing data streams that impede such inference and detail what data might be necessary to robustly infer timing of epidemics.
