Pedotransfer function to predict density of forest soils in Switzerland
Authors: Nussbaum Madlene , Papritz Andreas , Zimmermann Stephan , Walthert Lorenz 
Published: April 2016

AbstractSoil density is an important soil property, but respective measurements are usually scarce. With data from 559 mineral soil horizons (134 sites) we developed a linear regression pedotransfer function (PTF) for the density of forest soils (sieved to ≤ 2 mm). The field estimate of density was the most important covariate. RMSE of 0.205 Mg m−3andR2of 0.67, calculated on independent data (131 horizons), were better than the statistics obtained by published, recalibrated PTF (RMSE 0.271–0.324 Mg m−3;R20.28–0.42).

Published: April 2016

The dummy molecularly imprinted polymers were prepared by Pickering emulsion polymerization. 4,4′‐(1‐Phenylethylidene) bisphenol was selected as the dummy template to avoid the leakage of the target bisphenols. The microsphere particles were characterized by scanning electron microscopy and nitrogen adsorption–desorption measurements, demonstrating that the regular‐shaped and medium‐sized particles (40–70 μm) were obtained with a specific surface area of 355.759 m2/g and a total pore volume of 0.561 cm3/g. The molecular imprinting properties of the particles were evaluated by static adsorption and chromatographic evaluation experiments. The association constant and maximum adsorption amount of bisphenol A were 0.115 mmol/L and 3.327 μmol/g using Scatchard analysis. The microsphere particles were then used as a solid‐phase extraction sorbent for selective extraction of seven bisphenols. The method of dummy molecularly imprinted solid‐phase extraction coupled with high‐performance liquid chromatography and diode array detection was successfully established for the extraction and determination of seven bisphenols from environmental sediment samples with method detection limits of 0.6–1.1 ng/g. Good recoveries (75.5–105.2%) for sediment samples at two spiking levels (500 and 250 ng/g) and reproducibility (RSDs < 7.7%, n = 3) were obtained.

Authors: Xiang Qiuyue , Hashi Yuki , Chen Zilin 
Published: April 2016

A rapid and sensitive ultra high performance liquid chromatography with electrospray ionization tandem mass spectrometry method was developed and validated for the simultaneous determination of eight major active components (magnoflorine, menisperine, 20‐hydroxyecdysone, cepharanthine, columbamine, jatrorrhizine, columbin, and palmatine) in Radix Tinosporae. The separation was performed on an InterSustainSwift C18 column (1.9 μm, 2.1 id × 100 mm) at 40 °C with a gradient elution. A mixture of acetonitrile and methanol (v/v = 1:1) and ammonium acetate buffer (25 mmol/L ammonium acetate with 0.2% formic acid) were used as mobile phases, and the flow rate was set at 0.4 mL/min. The recovery was tested in real samples and calculated to be 86.97–111.28%, and all the compounds showed good linearity (r > 0.998) in relatively wide concentration ranges. The developed method was applied to the determination of eight active compounds in real herb samples, which were collected from four different places. It has been demonstrated that the proposed method has great potential for the quality control of the traditional Chinese medicine Radix Tinosporae.

Published: April 2016

An automatic on‐line solid‐phase extraction with ultra‐high performance liquid chromatography and tandem mass spectrometry method was developed for the simultaneous determination of ten antipsychotics in human plasma. The plasma sample after filtration was injected directly into the system without any pretreatment. A Shim‐pack MAYI‐C8 (G) column was used as a solid‐phase extraction column, and all the analytes were separated on a Shim‐pack XR‐ODS III column with a mobile phase consisting of 0.1% v/v formic acid in water with 5 mM ammonium acetate and acetonitrile. The method features were systematically investigated, including extraction conditions, desorption conditions, the equilibration solution, the valve switching time, and the dilution for column‐head stacking. Under the optimized conditions, the whole analysis procedure took only 10 min. The limits of quantitation were in the range of 0.00321–2.75 μg/L and the recoveries ranged from 75.9 to 122%. Compared with the off‐line ultra‐high performance liquid chromatography and the reported methods, this validated on‐line method showed significant advantages such as minimal pretreatment, shortest analysis time, and highest sensitivity. The results indicated that this automatic on‐line method was rapid, sensitive, and reliable for the determination of antipsychotics in plasma and could be extended to other target analytes in biological samples.

Published: April 2016

Objectives/HypothesisDemonstrate that biofilm formation will be reduced on tracheoesophageal prostheses when vibratory stimulus is applied, compared to controls receiving no vibratory stimulus, in a dynamic in vitro model of biofilm accumulation simulating the interface across the tracheoesophageal puncture site.Study DesignProspective, randomized, controlled, crossover in university laboratory.MethodsEx vivo tracheoesophageal prostheses were obtained from university‐affiliated speech language pathologists at Indiana University School of Medicine, Indianapolis. Prostheses demonstrating physical integrity and an absence of gross biofilm accumulation were utilized. Sixteen prostheses were cleansed and sterilized prior to random placement by length in two modified Robbins devices arranged in parallel. Each device was seeded with a polymicrobial oral flora on day 1 and received basal artificial salivary flow continuously with three growth medium meals daily. One device was randomly selected for vibratory stimulus, and 2 minutes of vibration was applied to each prosthesis before and after meals for 5 days. The prostheses were explanted and sonicated, and the biofilm cultured for enumeration. This process was repeated after study arm crossover.ResultsTracheoesophageal prostheses in the dynamic model receiving vibratory stimulus demonstrated reduced gross biofilm accumulation and a significant biofilm colony forming unit per milliliter reduction of 5.56‐fold compared to nonvibratory controls (P < 0.001). Significant reductions were observed within length subgroups.ConclusionApplication of vibratory stimulus around meal times significantly reduces biofilm accumulation on tracheoesophageal prostheses in a dynamic in vitro model. Further research using this vibratory stimulus method in vivo will be required to determine if reduced biofilm accumulation correlates with longer device lifespan.Level of EvidenceNA Laryngoscope, 126:2752–2757, 2016

Published: April 2016

AbstractModeling sediment yield is a complex task because of the nonlinearity of natural processes intervening at slope and basin scale. In this study slope steepness, vegetation cover, and soil properties along with sediment yield were studied in 20 pasture micro‐catchments in a semi‐arid region, NW Iran in order to understand and predict sediment yield. The micro‐catchments included only one first‐order gully and drain toward a rock check dam in the outlet. The sediment yield of each micro‐catchment was calculated using the measurement of sediment mass in the check dams for a 16‐year period (1994–2010). Relationships between sediment yield and drainage characteristics were analyzed using correlation matrix and multiple linear regression method. Based on the results, sediment yield in the micro‐catchments varied from 0.29 Mg ha−1 y−1 to 14.81 Mg ha−1 y−1, with an average of 5.04 Mg ha−1 y−1. It was significantly related to slope steepness, vegetation cover, and soil organic matter using a linear regression equation (R2 = 0.87, p < 0.001). The slope, vegetation, and soil organic matter explained about 44%, 23%, and 20% of total variance in sediment yield, respectively. The spatial validation of the model using data from eight different micro‐catchments located nearby showed that the model efficiency is 0.94. Therefore, the model can be used for predicting sediment yield in this and similar study area, with a high degree of accuracy. Copyright © 2016 John Wiley & Sons, Ltd.

ScopeChanges in genetic variations affecting the taste receptor, type 2, member 38 (TAS2R38) may identify the interacting mechanism leading to obesity and potential associations with proteins partaking in innate immunity, such as surfactant protein D (SPD) and mannan‐binding lectin (MBL).Methods and resultsWe evaluated haplotypes of the bitter‐taste receptor TAS2R38 in an identification sample of 210 women in different weight conditions, including anorexia nervosa and obesity. The association with SPD and MBL was tested in an independent sample picturing general population (n = 534). The relationship with obesity was validated in an extended final sample of 1319 participants. In the sample comprised of women in extreme weight conditions, increased obesity was identified in AVI/AVI subjects (OR = 2.5 [1.06–6.11], p = 0.035). In the sample picturing general population, increased SPD and MBL concentrations were found in nonsmoking AVI carriers. In this cohort, smoking and obesity blunted associations between TAS2R38 haplotypes and SPD and MBL. In the extended sample, the association of AVI/AVI haplotypes with increased obesity was also identified (OR = 1.4 [0.99/1.85], p = 0.049), being more robust in subjects aged <40 years (OR = 1.9 [1.06/3.42], p = 0.031).ConclusionCurrent data reinforce the impact of TAS2R38 gene on phenotypic and clinical outputs affecting obesity, showing significant associations with extreme weight conditions (i.e., obesity and anorexia nervosa), and changes in both olfactory capacity and immune traits.
Isolated gluteal and paravertebral muscle weakness due to anti‐3‐hydroxy‐3‐methylglutaryl‐coenzyme a reductase antibody–associated necrotizing autoimmune myopathy
Authors: McGrath Nicole M. , Turner Clinton P. 
Published: April 2016

AbstractIntroduction: A 56‐year‐old man with a distant history of statin use presented with progressive isolated very proximal lower limb and truncal weakness. Electromyogram (EMG) showed isolated gluteal and lumbar paraspinal muscle involvement. Methods: Gluteus medius muscle biopsy was performed under general anesthesia. Results: The biopsy showed a pauci‐inflammatory necrotizing myopathy. Serum antibodies to 3‐hydroxy‐3‐methylglutaryl‐coenzyme A reductase (HMGCR) were positive. He has since partially responded to corticosteroids and methotrexate. Conclusions: Anti‐HMGCR–associated necrotizing autoimmune myopathy (NAM) can present in a restricted form after cessation of a statin. Biopsy of a symptomatic but uncommonly studied muscle is worthwhile. Muscle Nerve 54: 150–152, 2016
Nocturia as a marker of poor health: Causal associations to inform care
Authors: Bower Wendy F. , Whishaw D. Michael , Khan Fary 
Published: April 2016

AimsNocturia is a common symptom of many conditions and is encountered in patients presenting to services across different medical specialities and health disciplines. The causal pathway of nocturia is multi‐factorial and differs between patients. There is currently no symptom‐specific clinical algorithm for all‐cause diagnosis of nocturia. The aim of this study was to investigate the interrelationships between causes of nocturia in order to inform the development of a comprehensive multidisciplinary assessment metric.MethodsA PubMed search that identified studies reporting relationships between nocturia and a priori aetiological factors was conducted by cross referencing the term “nocturia” with “polyuria, postural hypotension, hypertension, cardiac function, heart failure, depression, anxiety, polypharmacy, sleep disturbance, sleep disorder, apnoea, and lower urinary tract symptoms.” Directed acyclic graphs (DAGS) were constructed to visually represent causal assumptions and to identify underlying relationships.ResultsThis study confirmed that causality of nocturia can be expressed in a directed acyclic graph, with the key variables being cardiovascular dysfunction, polyuria, sleep disturbance, mental health, metabolic and inflammatory changes, health status and lower urinary tract symptoms. None of the variables were independently a sufficient or necessary direct cause of nocturia and multiple backdoor pathways exist to nocturnal voiding. Polypharmacy, increasing age and BMI all have confounding effects.ConclusionsThere are significant interactions between voiding at night and metabolic, cardiovascular, hormonal, mental health, sleep and inflammatory changes that flag nocturia as a likely marker of co‐morbid poor health. Patients should be comprehensively evaluated for all‐causes of nocturia since multiple aetiologies commonly co‐exist. Neurourol. Urodynam. 36:697–705, 2017. © 2016 Wiley Periodicals, Inc.
A multibody meshfree strategy for the simulation of highly deformable granular materials
Authors: Mollon Guilhem 
Published: April 2016

SUmmaryIn this paper, a multibody meshfree framework is proposed for the simulation of granular materials undergoing deformations at the grain scale. This framework is based on an implicit solving of the mechanical problem based on a weak form written on the domain defined by all the grains composing the granular sample. Several technical choices, related to the displacement field interpolation, to the contact modelling, and to the integration scheme used to solve the dynamic equations, are explained in details. A first implementation is proposed, under the acronym Multibody ELement‐free Open code for DYnamic simulation (MELODY), and is made available for free download. Two numerical examples are provided to show the convergence and the capability of the method. Copyright © 2016 John Wiley & Sons, Ltd.

Authors: Mahaffey Ryan , Morrison Stewart C. , Stephensen David , Drechsler Wendy I. 
Published: April 2016

ObjectiveMeasuring physical function in children with obesity is important to provide targets for clinical intervention to reduce impairments and increase participation in activities. The objective of this integrative review was to evaluate measurement properties of performance‐based measures of physical function in children with overweight and obesity.Design and MethodsAn integrative review of literature published in Cochrane Reviews, SPORTDiscus, CINAHL, PLoS, Medline, and Scopus was conducted.ResultsTwenty‐eight studies were eligible and represented 66 performance‐based measures of physical function. Assessments of repeatability and feasibility were not conducted in the majority of performance measures reported; only 6‐min‐timed walk (6MTW) was examined for test‐retest repeatability. Measures of flexibility, strength, aerobic performance, anaerobic performance, coordination, and balance demonstrated construct validity and responsiveness; however, findings were inconsistent across all performance‐based measures. Multi‐item tests of physical function demonstrated acceptable construct validity and responsiveness; however, internal consistency was not determined.ConclusionsThere is moderate evidence that 6MTW is suitable for the measurement of physical function in children with obesity. However, evidence is low for the use of aerobic and anaerobic performance, muscle strength, Movement Assessment Battery for Children, and Bruininks‐Oseretsky Test of Motor Proficiency multi‐item performance instruments and very low for flexibility, coordination, and balance tests. Based on this review, measurement of physical function using 6MTW is recommended.
Broadening Benefits from Natural Resource Extraction: Housing Values and Taxation of Natural Gas Wells as Property
Authors: Weber Jeremy G. , Burnett J. Wesley , Xiarchos Irene M. 
Published: April 2016

AbstractWe study the effects of the property tax base shock caused by natural gas drilling in the Barnett Shale in Texas—a state that taxes oil and gas wells as property. Over the boom and bust in drilling, housing appreciation closely followed the oil and gas property tax base, which expanded the total tax base by 23 percent at its height. The expansion led to a decline in property tax rates while maintaining or increasing revenues to schools. Overall, each $1 per student increase in the oil and gas property tax base increased the value of the typical home by $0.15. Some evidence suggests that the cumulative density of wells nearby may lower housing values, indicating that drilling could reduce local welfare without policies to increase local public revenues.

Published: April 2016

AbstractBackgroundCHARGE syndrome is a multiple congenital anomaly syndrome caused by mutations in CHD7. Diagnostic criteria have been proposed to improve diagnosis in fetuses at clinicopathological survey, but no criteria exist for fetal diagnosis during pregnancy.MethodWe collected prenatal findings of 12 children with CHARGE syndrome diagnosed in the first 3 months and a CHD7 mutation. We retrieved data on prenatal ultrasound (US) follow‐up, fetal supplementary investigations, and results of postnatal evaluation.ResultSeven pregnancies were complicated by the identification of isolated or multiple congenital anomalies. CHARGE syndrome was suspected in three fetuses but could not be confirmed despite additional examinations. Retrospectively, several postnatal findings could have been seen if they had been specifically searched. Intrauterine growth restriction, previously proposed as an exclusion criterion, complicated two pregnancies and is thus compatible with the diagnosis.ConclusionDiagnosis of CHARGE syndrome remains difficult during pregnancy. If the diagnosis of CHARGE syndrome is raised in utero, we suggest a careful US examination to identify typical external ears, choanal atresia, or microphthalmia. Fetal brain magnetic resonance imaging can be helpful, but a normal result does not exclude the diagnosis. When CHARGE syndrome is highly suspected, CHD7 molecular analysis must be proposed to confirm the diagnosis. © 2016 John Wiley & Sons, Ltd.

Authors: González Seligra Paula , Eloy Moura Lídia , Famá Lucia , Druzian Janice Izabel , Goyanes Silvia 
Published: April 2016

AbstractFilms of PBAT/TPS (poly(butylene adipate‐co‐terephthalate)/thermoplastic starch) (starch plasticized with glycerol containing citric and stearic acids) without and with 0.6 wt% starch nanoparticles were produced by extrusion. The presence of nanoparticles during the extrusion process led to a higher degree of starch gelatinization improving starch compatibility with PBAT. Nanoparticles modified the interaction between the different components of the PBAT/TPS composite. The hydroxyl groups of the starch nanoparticles interacted with starch amylose by means of hydrogen bonds. In addition, nanoparticles modified the structure of the PBAT rigid segment (BT): a shift of Tm of BT toward lower temperatures and a slight shift of the relaxation of the BT segment to higher temperatures were observed. The incorporation of nanoparticles also had a reinforcing effect on the PBAT/TPS matrix. The composite presented slight increases of Young's modulus (E) and stress at break (σb) without affecting the strain at break (ϵb). The rate of biodegradability was improved with the use of starch nanoparticles. The composite showed faster deterioration than the matrix, showing the first changes in its tonality and breakdowns at only 6 days of burial in compost. © 2016 Society of Chemical Industry
Precision ADMET polyolefins containing dithiane: Synthesis, thermal properties, and macromolecular transformation
Authors: Song Shaofei , He Feng , Fu Zhisheng , Xu Junting , Fan Zhiqiang 
Published: April 2016

ABSTRACT1,3‐Dithiane and its derivatives are widely used as powerful acyl anion equivalent to a range of useful transformations that are needed in the synthesis of natural products. In this work, a series of polyolefins containing pendant dithiane groups have been designed and synthesized via acyclic diene metathesis polymerization (ADMET) polymerization and subsequent hydrogenation. The structures of these polymers were characterized by 1H NMR, 13C NMR, and FT‐IR, and successful incorporation of the dithiane groups was proved. With different contents of the dithiane moieties, these ADMET polymers exhibited distinct thermal properties different from each other as evidenced by differential scanning calorimetry and thermal gravimetric analysis. The dithiane units in the ADMET polymer with 20 methylene carbons between the adjacent dithiane groups were transformed into thiol groups via reaction with Bu3SnH. This work provided a convenient route to synthesize polyethylene with pendant thiol groups that are evenly distributed in the chain. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
