Authors: Jirasek Fabian , Garcia Edder J. , Hackemann Eva , Galeotti Nadia , Hasse Hans 
Published: September 2018

AbstractThe partial molar volume of lysozyme and bovine serum albumin in aqueous solutions at different pH values and in aqueous solutions containing sodium chloride, ammonium chloride, sodium sulfate, or ammonium sulfate at different concentrations at pH 7.0 was investigated experimentally at 298.15 K and 1 bar. It was found that the influence of the pH value and the salts on the partial molar volume of the proteins is small, but trends were measurable. Furthermore, the partial molar volume of lysozyme in pure water at different pH values and in aqueous solutions with different sodium chloride concentrations at pH 7.0 was predicted by molecular simulations. The predictions are in good agreement with the experimental data.

Published: September 2018

AbstractA highly sensitive homogeneous electrochemiluminescence (ECL) biosensor for folate receptor (FR) has been developed based on hyperbranched rolling circle amplification (HRCA) and terminal protection. FR was combined to folic acid modified single stranded DNA (FA‐ssDNA) through the strong affinity between FA and FR, which prevented ssDNA from enzymolysis of exonuclease I (Exo I). The protected ssDNA was then applied as a template of padlock looping to trigger the HRCA proceeding. The products of HRCA contains large amount of double strand DNA (dsDNA), which provided excellent carries for Ru(phen)32+ intercalation. The extra free Ru(phen)32+ was removed by ultrafiltration and the Ru(phen)32+ embedded into dsDNA can act as a high‐efficiency ECL indicator to quantify the FR concentration. The enhanced ECL intensity had a linear relationship with logarithm of FR concentration in the range of 4 fM to 120 pM with a correlation coefficient of 0.998. Furthermore, the proposed ECL biosensor has been applied to detect FR in Hela cells and showed a linear relationship with the logarithm of cell concentration ranging from 100–5000 cell/mL. Compared to other FR biosensors, the proposed ECL biosensor presents the merits of the simplicity, high sensitivity and specificity, which shows the great potential application in the field of early cancers diagnosis.
Sidearm Modified Bisoxazoline Ligands and Their Applications
Authors: Wang Lijia , Zhou Jian , Tang Yong 
Published: September 2018

AbstractDeveloping novel and highly efficient chiral ligands is the eternal theme in chiral catalysis research, since none of ligands or catalysts is universal for all the reactions. We are aiming at searching for a facile and effective strategy in developing new chiral ligands that could be employed in a broad range of asymmetric reactions. By introducing additional (sidearm) groups to a classic chiral ligand, both the electron nature and steric environment of the catalyst could be adjusted, and thus the reactivity, selectivity and functional group tolerance of a catalyst could be modulated. Based on this strategy, a variety of sidearm modified bisoxazoline ligands have been designed and developed, including TOX, SaBOX, diSaBOX and Wing‐BOX. The account presents a brief introduction on their discovery and representative applications.
Effects of experimental parameters on simultaneous removal of SO2 and NO by VUV/H2O2 advanced oxidation process in a pilot‐scale photochemical spraying tower

Published: September 2018

AbstractBackgroundEmissions of SO2 and NO from flue gas have caused serious environmental pollution issues. UV/vacuum ultraviolet(VUV)‐activated H2O2 advanced oxidation technology is one of the most promising processes to realize the simultaneous removal of SO2 and NO. From the application perspective, it is necessary to carry out further research in a pilot‐scale photochemical reactor with industrial conditions and actual coal‐fired flue gas running conditions.ResultsResults showed that SO2 removal efficiency can reach 100% under most experimental conditions. An increase of the VUV irradiation intensity, H2O2 concentration and solution pH can promote NO removal, but the growth rate of that gradually slows down. It is not conducive to NO removal when the flue gas flow and NO concentration increases. Increasing liquid–gas ratio has dual effects on NO removal; NO removal efficiency increases at first, and then decreases sharply. SO2 concentration has no great impact on removal of NO. Results of ion chromatography (IC) demonstrate that SO42− and NO3− are the major removal products of SO2 and NO.ConclusionThe VUV‐activated H2O2 advanced oxidation technology is suitable for industrial application. The investment and operating costs of this technology are lower than those of the combined processes NH3‐SCR and Ca‐WFGD. © 2018 Society of Chemical Industry

AimsThis paper presents 18‐month follow‐up results for patients enrolled in a pivotal study conducted to support an FDA premarket approval application (PMAA). The trial evaluated the safety and efficacy of the ProACT Adjustable Continence Therapy for the treatment of post‐prostatectomy stress urinary incontinence (SUI).MethodsThe clinical study involved 11 clinical sites and enrolled 160 subjects. A total of 124 subjects met study criteria and 123 underwent ProACT implantation from July 2005 through June 2007, of whom 98 completed 18‐month follow‐up. Endpoints included 24‐h pad weight, Incontinence Quality of Life Questionnaire (I‐QOL), UCLA Prostate Cancer Index‐Urinary Function (PCI‐UF), residual volume, and device or procedure‐related adverse events (AEs).ResultsThe mean surgical time was 32 min. Statistically significant improvements during follow‐up were observed in 24‐h pad weight, for which the cohort mean pre‐implant urine loss was 399 g, which was reduced at 18 months to 160 g (P < 0.001). Reductions in pad weight were observed across all levels of pre‐implant SUI severity. Significant improvements were also seen in quality of life as measured by the I‐QOL (P < 0.001) as well as measures of urinary function and pad count. One procedure‐related serious adverse event (SAE), retention, was reported among the 124 subjects; the SAE was resolved without clinical meaningful sequalae.ConclusionsThese results demonstrate the safety and efficacy of this newly FDA‐approved therapy, showing significant improvements in objective and subjective measures of SUI in mild, moderate, and severely incontinent male patients. The duration of the implant procedure is short, and complications are mild and easily resolvable.
Novel superabsorbent materials from bacterial cellulose

Published: September 2018

AbstractA novel process for the production of superabsorbent materials (hydrogels) from bacterial cellulose (BC) was developed. Prior to crosslinking with a water‐soluble polyethylene glycol diacrylate (PEGDA), BC was first carboxymethylated and functionalized with glycidyl methacrylate. The degree of crosslinking influenced the swelling properties of the hydrogels. The use of greater amounts of PEGDA enhanced the formation of a thicker macromolecular network containing fewer capillary spaces in the crosslinked gel. The maximum water retention value of the hydrogels containing 2.5–3.5 mmol of carboxyl groups per gram of gel reached 125 g g−1 in distilled water, and 29 g g−1 in saline (0.9% NaCl solution). The highly porous hydrogel architecture with a pore size of 350–600 µm created a high specific surface area. This enables rapid mass penetration in superabsorbent applications. The superabsorbent hydrogels reached 80% of their maximum water absorption capacity in 30 min. © 2018 Society of Chemical Industry
A tradeoff resource allocation based on MF‐TDMA scheme in the multibeam data relay satellite systems

Published: September 2018

SummaryA tremendous increase in the number of distributed satellite constellations with the unscheduled burst data traffic will impose addition and diverse requirements on the DRS (data relay satellite) systems, which increases the complexity for beam management and affects a real‐time data return and acquisition. In this paper, we suggested that a large capacity can be achieved by a multibeam DRS system based on multifrequency time division multiple access scheme providing multiaccess for the distributed satellite constellations. Because the space‐based information network is characterized by the limited on‐board resources, a highly dynamic topology and time‐varying intersatellite links, we designed a 2‐stage dynamic optimization approach to separate the multiobjective optimization for frequency/time blocks and power, aiming at the rapidly converging to the optimal solution and at the same time meeting the fairness resource allocation. In particular, a capacity‐fairness tradeoff algorithm is proposed based on hybrid the enhanced genetic algorithm and the particle swarm optimization. Simulation results show that the tradeoff between maximizing total capacity and providing proportional fairness allocation is well balanced. The proposed algorithm can rapidly converge to adapt to the highly dynamic topology in data relay satellite systems.

Published: September 2018

Shale gas could help address the insatiable global demand for energy. However, in addition to risks of environmental pollution, the risk of induced seismicity during the hydraulic fracturing process is often considered as the major showstopper in the public acceptability of shale gas as an alternative source of fossil fuel. Other types of subsurface energy development have also demonstrated similar induced seismicity risks. This article presents an interdisciplinary review of notable cases of suspected induced seismicity relating to subsurface energy operations, covering operations for hydraulic fracturing, wastewater injection, conventional gas extraction, enhanced geothermal systems and water impoundment. Possible causal mechanisms of induced seismicity are described and illustrated, then methods to mitigate induced seismicity, encompassing regulations, including so‐called traffic light systems, monitoring and assessment, and numerical modeling approaches for predicting the occurrence of induced seismicity are outlined. Issues relating to public perception of energy technologies in regards to induced seismicity potential are also discussed.This article is categorized under:Photovoltaics > Climate and EnvironmentFossil Fuels > Climate and EnvironmentEnergy Infrastructure > Economics and PolicyEnergy and Development > Systems and Infrastructure

Abstract
Utilization of renewable and low-cost lignocellulosic wastes has received major focus in industrial lactic acid production. The use of high solid loadings in biomass pretreatment potentially offers advantages over low solid loadings including higher lactic acid concentration with decreased production and capital costs. In this study, an isolated Enterococcus faecalis SI with optimal temperature 42 °C was used to produce optically pure l-lactic acid (&gt; 99%) from enzyme-saccharified hydrolysates of acid-impregnated steam explosion (AISE)-treated plywood chips. The l-lactic acid production increased by 10% at 5 L scale compared to the similar fermentation scheme reported by Wee et al. The fermentation with a high solid loading of 20% and 35% (w/v) AISE-pretreated plywood chips had been successfully scaled up to process development unit scale (100 L) and pilot scale (9 m3), respectively. This is the first report of pilot-scale lignocellulosic lactic acid fermentation by E. faecalis with high lactic acid titer (nearly 92 g L−1) and yield (0.97 kg kg−1). Therefore, large-scale l-lactic acid production by E. faecalis SI shows the potential application for industries.

ABSTRACT

Introduction:
The effects of bariatric surgery on improvement of the metabolic syndrome is well-described, but its effect on intrinsic bone fragility and fracture propagation is unclear. Therefore, the aims of this systematic review of the literature were to examine (1) the incidence of fracture following bariatric surgery, (2) the association of fracture with the specific bariatric surgical procedure, and (3) site-specific types of fractures associated with bariatric surgery.

Methods:
A comprehensive literature search was conducted through Medline, Embase, Scopus, Web of Science, Dare, Cochrane library, and HTA database. The search terms used were gastric bypass, sleeve gastrectomy and fracture.

Results:
Eight studies were included (n = 42,567 patients). This included no randomized controlled trials. The average patient age was 43.3 years and 24.9% of patients were male. The average follow-up time was 3.7 years. 1960 patients had at least one fracture, and the total number of fractures encountered was 2326. Overall, 4.6% of patients who underwent bariatric surgery suffered from a fracture post-operatively. The operation associated with the greatest risk of fractures post-operatively was following a biliopancreatic diversion (10.66%), followed by restrictive procedures such as adjustable gastric band and sleeve gastrectomy (5.71%), with the Roux-en-Y gastric bypass having the lowest risk (2.66%). Of the fractures encountered, 1458 (63.08%) were of the lower extremity and pelvis and 763 (33.01%) were of the upper extremity. Only 90 (3.89%) axial skeleton fractures were reported.

Conclusions:
The overall risk of sustaining a fracture of any type after undergoing bariatric surgery is approximately 5 percent after an average follow up of 3.7 years. The greatest risk of fractures is associated with the biliopancreatic diversion surgery, with the Roux-en-Y gastric bypass being the most favorable. Fractures following bariatric surgeries tend to occur mostly in the lower extremity and pelvis.

Radar evidence of ponded subglacial water in Greenland

Published: September 2018

ABSTRACTThe thermal state at the bed of a large ice sheet is a critical boundary condition governing its future evolution. Radar surveys provide an opportunity for direct but remote observation of the ice-sheet bed, and therefore offer a means of constraining numerical ice-sheet models at the ice–bed interface. Here we have processed results of radar surveys of the Greenland Ice Sheet undertaken by the Program for Arctic Regional Climate Assessment (PARCA) between 1999 and 2003, to explore this opportunity. We consider the robustness of the measurements in the context of uncertain dielectric losses in the ice sheet, concluding that the observed radar signal characteristics reflect the character of the bed itself rather than that of uncertain englacial absorption. However, the identification of thaw is restricted to areas where subglacial water has sufficient depth to influence the radar reflection. We derive a map of inferred areas of subglacial thaw, and compare our results with other studies predicting regions with temperate bed. We show that in many areas the radar inferences of ponded water lie within areas predicted to be thawed by modelling and radiostratigraphy. There is clear disagreement in certain areas, suggesting the presence of high geothermal flux anomalies.
Support for Coups in the Americas: Mass Norms and Democratization
Authors: Cassell Kaitlen J. , Booth John A. , Seligson Mitchell A. 
Published: September 2018

AbstractCoups d’état, once a common end for democracies in the Americas, have declined sharply in recent years. This article investigates whether overall public support for coups is also in decline. Examining 21 countries in Latin America and the Caribbean from 2004 to 2014 helps to evaluate two alternative theses on democratization: Mainwaring and Pérez-Liñán’s 2013 normative regime preferences theory, which inquires (but does not test) whether public opinion can signal to elites a reluctance or willingness to support a coup; and classic modernization theory (Inglehart 1988; Inglehart and Welzel 2005). We find a substantively meaningful effect of democratic attitudes on coup support and a weak effect for national wealth, from which we infer that evolving elite values and preferences are paralleled at the mass level and that together, those two trends play a stronger role in the consolidation of democratic regimes than does modernization.

Published: September 2018

AbstractThe aim of this study was to characterise changes in lean soft tissue (LST) and examine the contributions of energy intake, physical activity and breast-feeding practices to LST changes at 3 and 9 months postpartum. We examined current weight, LST (via dual-energy X-ray absorptiometry), dietary intake (3-d food diary), physical activity (Baecke questionnaire) and breast-feeding practices (3-d breast-feeding diary) in forty-nine women aged 32·9 (sd3·8) years. Changes in LST varied from −2·51 to +2·50 kg with twenty-nine women gaining LST (1·1 (sd0·7) kg,P<0·001) and twenty women losing LST (−0·9 (sd0·8) kg,P<0·001). Energy intake (133 (SD42)v.109 (SD33) kJ/kg,P=0·019) and % kJ from fat at 3 months postpartum was higher in women who gained LST at 9 months postpartum (gained LST=34 (sd5) % kJ; lost LST=29 (sd4) % kJ,P=0·002). Women who gained LST reported breast-feeding their infants more frequently (gained LST=8 (sd3) feeds/d; lost LST=5 (sd1) feeds/d,P=0·014) and for more time per d (gained LST=115 (sd78) min/d; lost LST=59 (sd34) min/d,P=0·016) at 9 months postpartum. Energy intake and % kJ from fat at 3 months were significant predictors of LST gain (β=0·08 (se0·04) and 0·24 (se0·09), respectively). This suggests that gain in LST may be associated with more frequent and longer episodes of breast-feeding at 9 months postpartum as well as dietary intake early in the postpartum period.
Bulk tank milk ELISA to detect IgG1 prevalence and clustering to determine spatial distribution and risk factors of Fasciola hepatica-infected herds in Mexico
Authors: Villa-Mancera A. , Reynoso-Palomar A. 
Published: September 2018

AbstractFasciola hepatica is a helminth parasite that causes huge economic losses to the livestock industry worldwide. Fasciolosis is an emerging foodborne zoonotic disease that affects both humans and grazing animals. This study investigated the associations between climatic/environmental factors (derived from satellite data) and management factors affecting the spatial distribution of this liver fluke in cattle herds across different climate zones in three Mexican states. A bulk-tank milk (BTM) IgG1 enzyme-linked immunosorbent assay (ELISA) test was used to detect F. hepatica infection levels of 717 cattle herds between January and April 2015. Management data were collected from the farms by questionnaire. The parasite's overall herd prevalence and mean optical density ratio (ODR) were 62.76% and 0.67, respectively. The presence of clustered F. hepatica infections was studied using the spatial scan statistic. Three marked clusters in the spatial distribution of the parasite were observed. Logistic regression was used to test three models of potential statistical association from the ELISA results using climatic, environmental and management variables. The final model based on climatic/environmental and management variables included the following factors: rainfall, elevation, proportion of grazed grass in the diet, contact with other herds, herd size, parasite control use and education level as significant predictors. Geostatistical kriging was applied to generate a risk map for the presence of parasites in dairy herds in Mexico. In conclusion, the spatial distribution of F. hepatica in Mexican cattle herds is influenced by multifactorial effects and should be considered in developing regionally adapted control measures.
Multidimensional assessment of impulsivity-related measures in relation to externalizing behaviors

Published: September 2018

AbstractBackgroundTrait impulsivity is thought to play a key role in predicting behaviors on the externalizing spectrum, such as drug and alcohol use and aggression. Research suggests that impulsivity may not be a unitary construct, but rather multidimensional in nature with dimensions varying across self-report assessments and laboratory behavioral tasks. Few studies with large samples have included a range of impulsivity-related measures and assessed several externalizing behaviors to clarify the predictive validity of these assessments on important life outcomes.MethodsCommunity adults (N = 1295) between the ages of 30 and 54 completed a multidimensional assessment of impulsivity-related traits (including 54 self-report scales of personality traits implicated in impulsive behaviors, and four behavioral tasks purporting to assess a construct similar to impulsivity) and reported on five externalizing behavioral outcomes (i.e. drug, alcohol, and cigarette use, and physical and verbal aggression). We ran an exploratory factor analysis on the trait scales, and then a structural equation model predicting the externalizing behaviors from the three higher-order personality factors (i.e. Disinhibition v. Constraint/Conscientiousness, Neuroticism/Negative Emotionality, and Extraversion/Positive Emotionality) and the four behavioral tasks.ResultsRelations between the self-report factors and behavioral tasks were small or nonexistent. Associations between the self-report factors and the externalizing outcomes were generally medium to large, but relationships between the behavioral tasks and externalizing outcomes were either nonexistent or small.ConclusionsThese results partially replicate and extend recent meta-analytic findings reported by Sharma et al. (2014) to further clarify the predictive validity of impulsivity-related trait scales and laboratory behavioral tasks on externalizing behaviors.
