AbstractThe effects of intermolecular interactions by a series of haloaromatic halogen bond donors on the normal modes and chemical shifts of the acceptor pyrimidine are investigated by Raman and NMR spectroscopies and electronic structure computations. Halogen‐bond interactions with pyrimidine's nitrogen atoms shift normal modes to higher energy and upfield shift 1H and 13C NMR peaks in adjacent nuclei. This perturbation of vibrational normal modes is reminiscent of the effects of hydrogen bonded networks of water, methanol, or silver on pyrimidine. The unexpected observation of vibrational red shifts and downfield 13C NMR shifts in some complexes suggests that other intermolecular forces such as π interactions are competing with halogen bonding. Natural bond orbital analyses indicate a wide range of charge transfer is possible from pyrimidine to different haloaromatic donors and computed halogen bond binding energies can be larger than a typical hydrogen bond. These results emphasize the importance in strategic selection of substituents and electron withdrawing groups in developing supramolecular structures based on halogen bonding.

AbstractAimsHeart failure (HF) is a multi­organ, pro‐inflammatory syndrome that impairs bone metabolism. Pro‐inflammatory cytokines and bone catabolism enhance periodontal disease, a local inflammatory, bacteria‐induced disease that causes bone loss and periodontal soft tissue destruction.Methods and resultsMedical and dental examinations were performed on patients with HF (n = 39), following heart transplantation (post‐HTx, n = 38) and controls (n = 32). Blood, saliva, and gingival crevicular fluid were analysed for bone metabolism and inflammation markers. HF average New York Heart Association classification was III. Average time since HTx was 1414 days. Pro‐inflammatory tumour necrosis factor‐alpha was higher in HF and HTx as compared with controls (P < 0.05). Both HF and HTx participants had higher levels of bone resorption marker C‐terminal telopeptide and parathyroid hormone with subjects in the HF group having the highest serum levels of all groups (P ≤ 0.05). In contrast, 25‐hydroxyvitamin D was lowest in HF. HF patients had greater clinical attachment loss, cumulative pockets depth (greater than 3 mm) and probing depth (P < 0.05) as compared with controls. Cumulative pockets depth correlated significantly with measures of the inflammatory burden, β‐glucuronidase in saliva (r = 0.4863, P < 0.01), interleukin‐1b in saliva (r = 0.5149, P < 0.01), and gingival crevicular fluid (r = 0.6056, P < 0.001) in HF. However, adjustment of periodontal results for measures of oral hygiene (plaque, bleeding on probing), systemic 25‐hydroxyvitamin D, and race attenuated significant differences between groups.ConclusionsPatients with HF exhibit more severe periodontal disease associated with increased bone turnover markers when compared with control patients. However, local and systemic factors may account for this association and should be evaluated in future studies.

ABSTRACTBackgroundThe purpose of this study was to present our findings on the treatment completion rates and outcomes in geriatric patients with head and neck cancer treated with neoadjuvant chemotherapy followed by definitive therapy.MethodsGeriatric patients with locally advanced head and neck cancer who received neoadjuvant chemotherapy were selected for this analysis. Overall survival (OS) and progression‐free survival (PFS) were estimated.ResultsForty‐six of 49 patients completed neoadjuvant chemotherapy (93.9%). The compliance to local treatment was 73.3% and the median OS was 49.9 months (95% confidence interval [CI] = 22.0–77.8 months) in patients who received neoadjuvant chemotherapy for organ preservation (n = 15). In patients receiving neoadjuvant chemotherapy for technically unresectable disease, the corresponding figures were 82.06% and 9.0 months (95% CI = 5.9–12.1 months), respectively.ConclusionIndividualized neoadjuvant chemotherapy protocols in geriatric patients have high compliance rates to treatment and the median OS in geriatric patients treated for organ preservation is similar to that of young patients. © 2017 Wiley Periodicals, Inc.

Characteristics of cloud cluster over the steep southern slopes of the Himalayas observed by CloudSat
Authors: Chen Yilun , Fu Yunfei , Xian Tao , Pan Xiao 
Published: March 2017

ABSRACTA cloud cluster (CC) dataset is presented using CloudSat Cloud Profile Radar (CPR) observations from June to August, between 2006 and 2010. The CCs were defined by grouping contiguous cloud pixels using a defined criteria, including reflectivity, ‘cloud mask’, and topographic information. The characteristics of identified CCs were then analysed. Based on the complex topography of the southern Himalayas, four adjacent regions were selected, including the flat Gangetic Plains (FGP), the foothills of the Himalayas (FHH), the steep slope of the southern Himalayas (SSSH), and the Himalayan‐Tibetan Plateau (HTPT). The characteristics of the CCs in the four regions were different, and the distribution of the cloud‐top height gradually changed from bimodal (3 and 15 km) over the FGP and FHH, to unimodal (7–9 km) over the HTPT. From the plain to the Plateau, the average cloud‐top height and cloud‐base height increased after an initial decrease. The maximum reflectivity increased from −6 (plain) to 2 dBZ (slope areas), and then decreased to −2 dBZ (Plateau), which suggests that the CCs may produce precipitation on the slope. Maximum CCs occurred over the FHH. The characteristics of the CCs also showed semidiurnal variation, which may have been affected by the variation of the monsoon and the circulation over the mountain valley. According to the physical principles of the cloud‐type definitions from ISCCP, high‐level cirrus, deep convective CCs, and mid‐ to low‐level CCs were categorized. As the elevation increased, the cloud‐top height of the mid‐ to low‐level CCs also significantly increased to 8 km, whereas the cloud‐top height of the high‐level cirrus clouds decreased. Our results suggest that the different characteristics of CCs may be caused by a strong upward motion interacting with the terrain of the Himalayas.

AbstractBackgroundFoveal hypoplasia (FH) in the absence of albinism, aniridia, microphthalmia, or achromatopsia is exceedingly rare, and the molecular basis for the disorder remains unknown. FH is characterized by the absence of both the retinal foveal pit and avascular zone, but with preserved retinal architecture. SLC38A8 encodes a sodium‐coupled neutral amino acid transporter with a preference for glutamate as a substrate. SLC38A8 has been linked to FH. Here, we describe a novel mutation to SLC38A8 which causes FH, and report the novel use of OCT‐angiography to improve the precision of FH diagnosis. More so, we used computational modeling to explore possible functional effects of known SLC38A8 mutations.MethodsFundus autofluorescence, SD‐OCT, and OCT‐angiography were used to make the clinical diagnosis. Whole‐exome sequencing led to the identification of a novel disease‐causing variant in SLC38A8. Computational modeling approaches were used to visualize known SLC38A8 mutations, as well as to predict mutation effects on transporter structure and function.ResultsWe identified a novel point mutation in SLC38A8 that causes FH. A conclusive diagnosis was made using OCT‐angiography, which more clearly revealed retinal vasculature penetrating into the foveal region. Structural modeling of the channel showed the mutation was near previously published mutations, clustered on an extracellular loop. Our modeling also predicted that the mutation destabilizes the protein by altering the electrostatic potential within the channel pore.ConclusionOur results demonstrate a novel use for OCT‐angiography in confirming FH, and also uncover genotype–phenotype correlations of FH‐linked SLC38A8 mutations.
Multi‐Stakeholder Initiatives for Sustainable Development Goals: The Importance of Interlocutors
Authors: Fowler Alan , Biekart Kees 
Published: March 2017

SummaryThis article argues that the complex multi‐stakeholder arrangements anticipated for implementing Sustainable Development Goals call for a distinct type of host: an interlocutor. This central idea arises from new comparative research on multi‐stakeholder initiatives (MSIs) undertaken in four countries: Costa Rica, Indonesia, Kenya and Kyrgyzstan. This work adds a detailed dimension to meta‐studies on conditions for success and practical guides for establishing and running MSIs. It begins to fill a significant gap in knowledge by analysing the attributes and competencies required for effectively orchestrating MSIs as well as illuminating their relative significance over time. The context is an anticipated expansion in demand for finely tuned and skilled hosting of Sustainable Development Goals‐inspired MSIs. This task will probably be more complicated than MSIs associated with climate change and Millennium Development Goals, both of which saw business on the side lines with uneven attention paid to the principle of local ownership. Recognising and investing in interlocution as a pivotal role can increase the performance of internationally inspired MSIs which, to date, have a mixed but generally poor record of effectiveness. © 2017 The Authors Public Administration and Development Published by John Wiley & Sons Ltd.
The influence of a radical structure on the kinetics of photopolymerization
Authors: Kabatc Janina 
Published: March 2017

ABSTRACTA radical initiation ability of new initiating systems in photopolymerization of 2‐ethyl‐2‐(hydroxymethyl)‐1,3‐propanediol triacrylate has been investigated and presented. The evaluation of alkyltriphenyl‐ and tetraalkylborates, iodonium salts, N‐alkoxypyridinium salts, maleimides, phthalimides, 1,3,5‐triazine derivatives and others as a free radical source in combination with suitable photosensitizer for radical polymerization of triacrylate is described. It is assumed that the photochemical decomposition of a coinitiator molecule results in formation of free radicals, which further initiate polymerization. The order of activity of free radical sources on kinetic of photopolymerization was also presented. Different initiator activity can be explained by the difference in the decomposition rate constant and the reactivity of radicals formed toward the double bond of monomer. © 2017 Wiley Periodicals, Inc.

Rapid quantification and isotopic analysis of dissolved sulfur species
Authors: Smith Derek A. , Sessions Alex L. , Dawson Katherine S. , Dalleska Nathan , Orphan Victoria J. 
Published: March 2017

RationaleDissolved sulfur species are of significant interest, both as important substrates for microbial activities and as key intermediaries in biogeochemical cycles. Species of intermediate oxidation state such as sulfite, thiosulfate, and thiols are of particular interest but are notoriously difficult to analyze, because of low concentrations and rapid oxidation during storage and analysis.MethodsDissolved sulfur species are reacted with monobromobimane which yields a fluorescent bimane derivative that is stable to oxidation. Separation by Ultra‐Performance Liquid Chromatography (UPLC) on a C18 column yields baseline resolution of analytes in under 5 min. Fluorescence detection (380 nm excitation, 480 nm emission) provides highly selective and sensitive quantitation, and Time‐of‐Flight Mass Spectrometry (TOF‐MS) is used to quantify isotopic abundance, providing the ability to detect stable isotope tracers (either 33S or 34S).ResultsSulfite, thiosulfate, methanethiol, and bisulfide were quantified with on‐column detection limits of picomoles (μM concentrations). Other sulfur species with unshared electrons are also amenable to analysis. TOF‐MS detection of 34S enrichment was accurate and precise to within 0.6% (relative) when sample and standard had similar isotope ratios, and was able to detect enrichments as small as 0.01 atom%. Accuracy was validated by comparison to isotope‐ratio mass spectrometry. Four example applications are provided to demonstrate the utility of this method.ConclusionsDerivatization of aqueous sulfur species with bromobimane is easily accomplished in the field, and protects analytes from oxidation during storage. UPLC separation with fluorescence detection provides low‐μM detection limits. Using high‐resolution TOF‐MS, accurate detection of as little as 0.01% 34S label incorporation into multiple species is feasible. This provides a useful new analytical window into microbial sulfur cycling. Copyright © 2017 John Wiley & Sons, Ltd.

Clinico‐pathological Correlation of Thyroid Nodule Ultrasound and Cytology Using the TIRADS and Bethesda Classifications
Authors: Singaporewalla R. M. , Hwee J. , Lang T. U. , Desai V. 
Published: March 2017

AbstractBackgroundClinico‐pathological correlation of thyroid nodules is not routinely performed as until recently there was no objective classification system for reporting thyroid nodules on ultrasound. We compared the Thyroid Imaging Reporting and Data System (TIRADS) of classifying thyroid nodules on ultrasound with the findings on fine‐needle aspiration cytology (FNAC) reported using the Bethesda System.MethodsA retrospective analysis of 100 consecutive cases over 1 year (Jan–Dec 2015) was performed comparing single‐surgeon‐performed bedside thyroid nodule ultrasound findings based on the TIRADS classification to the FNAC report based on the Bethesda Classification. TIRADS 1 (normal thyroid gland) and biopsy‐proven malignancy referred by other clinicians were excluded. Benign‐appearing nodules were reported as TIRADS 2 and 3. Indeterminate or suspected follicular lesions were reported as TIRADS 4, and malignant‐appearing nodules were classified as TIRADS 5 during surgeon‐performed bedside ultrasound. All the nodules were subjected to ultrasound‐guided FNAC, and TIRADS findings were compared to Bethesda FNAC Classification.ResultsOf the 100 cases, 74 were considered benign or probably benign, 20 were suspicious for malignancy, and 6 were indeterminate on ultrasound. Overall concordance rate with FNAC was 83% with sensitivity and specificity of 70.6 and 90.4%, respectively. The negative predictive value was 93.8%.ConclusionIt is essential for clinicians performing bedside ultrasound thyroid and guided FNAC to document their sonographic impression of the nodule in an objective fashion using the TIRADS classification and correlate with the gold standard cytology to improve their learning curve and audit their results.

AbstractObjectivesThis UK‐wide study defines the natural history of argininosuccinic aciduria and compares long‐term neurological outcomes in patients presenting clinically or treated prospectively from birth with ammonia‐lowering drugs.MethodsRetrospective analysis of medical records prior to March 2013, then prospective analysis until December 2015. Blinded review of brain MRIs. ASL genotyping.ResultsFifty‐six patients were defined as early‐onset (n = 23) if symptomatic < 28 days of age, late‐onset (n = 23) if symptomatic later, or selectively screened perinatally due to a familial proband (n = 10). The median follow‐up was 12.4 years (range 0–53). Long‐term outcomes in all groups showed a similar neurological phenotype including developmental delay (48/52), epilepsy (24/52), ataxia (9/52), myopathy‐like symptoms (6/52) and abnormal neuroimaging (12/21). Neuroimaging findings included parenchymal infarcts (4/21), focal white matter hyperintensity (4/21), cortical or cerebral atrophy (4/21), nodular heterotopia (2/21) and reduced creatine levels in white matter (4/4). 4/21 adult patients went to mainstream school without the need of additional educational support and 1/21 lives independently. Early‐onset patients had more severe involvement of visceral organs including liver, kidney and gut. All early‐onset and half of late‐onset patients presented with hyperammonaemia. Screened patients had normal ammonia at birth and received treatment preventing severe hyperammonaemia. ASL was sequenced (n = 19) and 20 mutations were found. Plasma argininosuccinate was higher in early‐onset compared to late‐onset patients.ConclusionsOur study further defines the natural history of argininosuccinic aciduria and genotype–phenotype correlations. The neurological phenotype does not correlate with the severity of hyperammonaemia and plasma argininosuccinic acid levels. The disturbance in nitric oxide synthesis may be a contributor to the neurological disease. Clinical trials providing nitric oxide to the brain merit consideration.
Managerial Ties, Market Orientation, and Export Performance: Chinese Firms Experience
Authors: Yan Hui , He Xinming , Cheng Binwu 
Published: February 2017

ABSTRACTManagerial ties (MT) are important for business performance by providing firms access to valuable resources and protecting them from opportunism. Drawing on the resource-based view and the market orientation (MO) literature, we argue that (1) MT can help exporting firms to enhance export performance; and (2) MO will help strengthen the positive effect of MT as MO directs the value of MT for improvement of competitive strategy and customer experience with a market focus on generation, dissemination, and use of market intelligence concerning existing and potential customers and competitors. Using a sample of 230 Chinese exporting firms, we found that MT is linked to superior export performance, and the link is positively moderated by MO. Therefore, this study expands our understanding of how firms can not only improve their export performance through the development of MT, but also use MO to reinforce MT and export performance association.
Brough Hall, Catterick, and Thorpe Hall, Norwich: A Comment
Authors: Hodgetts Michael 
Published: February 2017

There was a time when recusant history was written almost entirely from documents and architectural evidence was ignored, except by authors like Camm and Squiers. But at least it could be argued then that papers were more perishable than brick and stone, and in more urgent need of recording and preservation. Less than twenty years ago, in 1958, the theme of the first Oxford Conference on recusant history was ‘The Vanishing Archive’. Today, a much graver threat is that of the vanishing building. An exhibition held in London recently to mark European Architectural Heritage Year included records of at least twenty-five recusant houses that have been demolished, and in the last three months there have been two more cases which illustrate the urgency of the problem.At the end of 1975, the Secretary for the Environment allowed the demolition of almost two-thirds of Brough Hall, near Catterick in Yorkshire. The central block of the house is Elizabethan and contains a priest-hole; about 1730 it was given a classical front, and forty years later two balancing wings were added by Thomas Atkinson. Now the east wing and all the centre except one pedimented bay are to be pulled down. This will mean the destruction of a panelled Elizabethan hall, of a Georgian room running the length of the first floor, of the hide, and of the Elizabethan friezes on the second floor. If, as often happens, the house must be reduced in size for economic reasons, the centre block should be preserved and the wings removed, as, for instance, at Mertoun in Berwickshire and (with the reluctant sacrifice of the chapel by William Ireland) at Houghton Hall in Yorkshire.
Forming capital: Emblematizing discourses of mobility in South Korea
Authors: Lo Adrienne , Choi Lee Jin 
Published: March 2017

AbstractThis article examines how listening subjects (Inoue 2006) mediate understandings of mobility in South Korea. Focusing on a cybercampaign to discredit the hip-hop star Tablo, it traces the ways that a listening public regimented signs relating to educational credentials, language, citizenship, and demeanor into forms of institutionalized, embodied, or objectified capital (Bourdieu 1986). Through the crafting of certain signs as icons that pointed to Tablo's ‘true’ character, and others as fronts, they were able to cast aspersions upon his command of English grammar, spelling, and interaction, and his character and educational credentials. By tracing how Tablo skeptics deployed metasemiotic discourses about emblems and figures of failed mobility, this article contributes to theories of semiosis that decenter the agentive speaking subject.

The ‘other woman’ in a mother and daughter relationship: The case of Mami Ji
Authors: Creese Angela , Blackledge Adrian 
Published: February 2017

ABSTRACTThis article describes the range of discursive strategies in the socializing messages of a mother and daughter interaction. The analysis draws on the work of Bakhtin (1981) and Tannen (2007) to interrogate the role of a physically absent but discursively present sister-in-law, ‘Mami Ji’, across three speech events. Following Tannen, we show how the characterisation of the sister-in-law, Mami Ji, has chronotopic value that connects mother and daughter in the present and makes links across family histories. Through the discursive strategies of repetition, dialogue, detail, and translanguaging, ‘Mami Ji’ becomes an iconic benchmark of how not to speak, how not to dress, and how not to behave. Drawing on material from a linguistic ethnography approach, we present three discourse analyses from a much larger international project that also looked at classroom interaction and break-time conversations. The article contributes to the under-researched topic of the representation of sisters-in-law in discourse, theorises the chronotope in everyday conversation, and demonstrates how mother and daughter solidarity is achieved through opposition to another female family member.
