Heme‐Dependent Oxidative N‐Demethylase
Authors: Ortmayer Mary , Leys David 
Published: December 2018

AbstractHeme‐dependent oxidative N‐demethylase (HODM) catalyzes the NADPH‐dependent oxidation or N‐dealkylation of dialkylamines to alkylamine. HODM is a heterotetrameric enzyme containing a histidine‐coordinated heme, flavin mononucleotide, 2Fe‐2S, and tetrahydrofolic acid cofactors. The alpha subunit is responsible for heme binding and contains a Per‐Arnt‐Sim domain fold. HODM functions in bacterial methylated amine catabolism, linking alkylamine oxidation to the tetrahydrofolate C1 pool. The discovery of the HODM operon allowed heterologous expression inEscherichia coliand biophysical/structural characterization reveled that the dimethylamine substrate plays a key role in a polarized oxygen‐binding site, highly evolved for oxygen activation.

AbstractPulse wave carries comprehensive information regarding the human cardiovascular system (CS), which is essential for directly capturing CS parameters. More importantly, cuffless blood pressure (BP) is one of the most critical markers in CS. Accurately measuring BP via the pulse wave for continuous and noninvasive diagnosis of a disease associated with hypertension remains a challenge and highly desirable. Here, a flexible weaving constructed self‐powered pressure sensor (WCSPS) is reported for measurement of the pulse wave and BP in a noninvasive manner. The WCSPS holds an ultrasensitivity of 45.7 mV Pa−1 with an ultrafast response time of less than 5 ms, and no performance degradation is observed after up to 40 000 motion cycles. Furthermore, a low power consumption sensor system is developed for precisely monitoring pulse wave from the fingertip, wrist, ear, and ankles. A practical measurement is performed with 100 people with ages spanning from 24 to 82 years and different health statuses. The discrepancy between the measured BP results using the WCSPS and that provided by the commercial cuff‐based device is about 0.87–3.65%. This work demonstrates an efficient and cost‐effective way for human health monitoring, which would be a competitive alternative to current complex cardiovascular monitoring systems.

AbstractChronic tympanic membrane (TM) perforations can cause otorrhea. To date, various types of tissue engineering techniques have been applied for the regeneration of chronic TM perforations. However, the application of nanofibers with radially aligned nanostructures and the simultaneous release of growth factors have never been applied in the regeneration of chronic TM perforations. Here, epidermal growth factor (EGF)–releasing radially aligned nanofibrous patches (ERA‐NFPs) are developed and applied for the regeneration of chronic perforated TMs. First, radial alignments and the presence of EGF in the ERA‐NFPs are analyzed. EGF is confirmed to be released from the ERA‐NFPs until 8 weeks. In an in vitro study, cell viability assay, immunocytochemistry, and wound‐healing assay indicate rational enhancement of healing by the combination of radial alignments and EGF release. The effect of ERA‐NFPs on TM cells is revealed by quantitative real‐time polymerase chain reaction. An in vivo animal study shows that the ERA‐NFPs effectively stimulates the healing of the chronic TM perforations. The TMs healed by ERA‐NFPs show histological properties similar to those of normal TMs. These results indicate that ERA‐NFPs may be an efficient platform for the regeneration of chronic TM perforations, laying the foundation for nonsurgical treatments of chronic otitis media.

AbstractGiven the global challenges of water scarcity, solar‐driven vapor generation has become a renewed topic as an energy‐efficient way for clean water production. Here, it is revealed that bamboo, as a natural hierarchical cellular material, can be an excellent 3D solar vapor‐generation device by a simple carbonization progress. A floating carbonized bamboo sample evaporates water with an extremely high vapor‐generation rate of 3.13 kg m−2 h−1 under 1 sun illumination. The high evaporation rate is achieved by the unique natural structure of bamboos. The inner wall of bamboo recovers the diffuse light energy and the thermal radiation heat loss from the 3D bamboo bottom, and the outer wall captures energy from the warmer environment. The high evaporation rate is also attributed to reduced vaporization enthalpy of water confined in the bamboo mesh. Such bamboo‐based high‐performance, low‐cost, self‐cleaning, solid durable, and scalable 3D vapor‐generation device has attractive applications in desalination as well as industrial and domestic wastewater abatement.
Finding the Sweet Spot: Investigating the Effects of Relationship Closeness and Instrumental Activities in School‐based Mentoring
Authors: Lyons Michael D. , McQuillin Samuel D. , Henderson Lora J. 
Published: December 2018

AbstractSchool‐based mentoring programs are popular prevention programs thought to influence youth development; but rigorous evaluations indicate that these programs often have small effects on youth outcomes. Researchers suggest that these findings may be explained by (a) mentors and mentees failing to develop a close relationship and (b) mentors not setting goals or focusing on specific skills necessary improve outcomes. We assessed these explanations using data from approximately 1360 mentor and mentee pairs collected through a national study of school‐based mentoring (called, “The Student Mentoring Program”). Specifically, we tested the influence of mentee‐reported relationship quality and mentor‐reported use of goal‐setting and feedback‐oriented activities on academic, behavioral, and social‐emotional outcomes. Results suggested that youth reported relationship quality was associated with small to medium effects on outcomes. Moreover, goal‐setting and feedback‐oriented activities were associated with moderate to large effects on outcomes. We also found significant interactions between relationship quality and goal‐setting and feedback‐oriented activities on youth outcomes. We conclude that there appears to be a “sweet‐spot” wherein youth outcomes are maximized. The results of this study suggest a need for school‐based mentoring programs to monitor and support mentors in developing a close relationship while also providing opportunities to set goals and receive feedback.

Published: December 2018

ABSTRACTCurrent vascular aneurysm treatments often require either highly invasive strategy to surgically occlude an aneurysm or endovascular occlusion via metal coils. While endovascular coils are safer, they have limited efficacy. Endovascular coils that are integrated with shape memory polymer (SMP) foams have the potential to improve occlusion and reduce coil risks; however, the mechanical performance and limited homogeneity of SMP foams can hinder their effective use. To address this issue, SMP foams are synthesized using the monomer diethanolamine (DEA) in place of triethanolamine (TEA) to provide improved mechanical properties for medical device applications. Mechanical testing and micro‐fracture analysis were performed on DEA and TEA foams. DEA foams show improved toughness and reduced micro‐fractures compared to the control. This work presents the utility of DEA in SMP synthesis to enable the potential production of safer aneurysm treatment. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47268.
The effects of natural astaxanthin‐modified silica on properties of natural rubber
Authors: Yao Bin‐bin , Xia Li‐jian , Wang Hui , Kan Ze 
Published: December 2018

ABSTRACTNatural astaxanthin is a natural substance extracted from algae such as Haematococcus pluvialis. Its molecular structure contains conjugated double bonds as well as keto and hydroxyl groups, and therefore it has high activity. In this research, natural astaxanthin was used to modify the surface of the silica, and its effects on natural rubber vulcanization properties, physical and mechanical properties, dynamic properties, and antiaging properties were studied by means of rubber process analyzer, dynamic mechanical anaylsis, and scanning electron microscopy. The results showed that natural astaxanthin‐modified silica could reduce the degree of delayed vulcanization. At the same time, the resilience and abrasion resistance of the obtained vulcanizates were increased. The DIN abrasion volume of the vulcanizates modified and reinforced by the second strategy decreased by 19.2% and 23.6%, respectively; the Payne effect of the natural astaxanthin‐modified silica/NR composites was weakened, and the dispersibility of the filler and the compatibility with the rubber matrix was significantly improved. Regardless of which strategy was used to modify the silica, the vulcanizates had a lower rolling resistance. Specially, it could greatly improve the hot air aging resistance property of rubber. Natural astaxanthin as being a renewable feedstock is expected to have a quite broad applications in the rubber industry. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 136, 47287.
Tannic acid coating and in situ deposition of silver nanoparticles to improve the antifouling properties of an ultrafiltration membrane

Published: December 2018

ABSTRACTThe construction of antifouling membranes has been a desirable approach for addressing membrane‐fouling issues in the ultrafiltration (UF) process. Antifouling means antiadhesive and antimicrobial; however, few researchers have achieved both properties in a facile and effective manner. In this article, we report a direct tannic acid (TA) coating method combined with the in situ deposition of silver nanoparticles (Ag NPs); this was used to improve the antifouling properties of a positively charged polymeric UF membrane. The results show that the TA–Ag NP modified membranes showed improved protein resistance (flux recovery rate = 71.2% after modification vs 17.8% before modification) and less attachment of bacteria (Escherichia coli K1) on the membrane surface and reduced cell viability in the resulting bacterial suspension (reduced by ≥90%) because of the combined antimicrobial properties of both the TA and Ag NPs. This indicated that our modification method was promising for UF membrane antifouling applications. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47314.

Published: December 2018

ABSTRACTSorption kinetics of pollutant oils, such as kerosene, virgin naphtha, crude oil, and pump oil, into porous siloxanic foams filled with carbon nanotubes (CNTs) are investigated. Both, pristine and functionalized, CNTs are used as foam fillers. Among all, the foam filled with pristine CNT shows a poor affinity with water and high sorption rate in light oils, in which it achieves the highest absorption values (7991 mg g−1 after 660 s and 6685 mg g−1 after 420 s, respectively, in virgin naphtha and kerosene). The kinetic data are described by the pseudo‐first order, pseudo‐second order, Elovich and intraparticle diffusion models. Results show that chemisorption processes are rate limiting the sorption step. In fact, pseudo‐second order model better represents the equilibrium isotherm data. © 2018 Wiley Periodicals, Inc. J.

Published: December 2018

AbstractAn electrochromic device with the as‐obtained nanoporous NiO /ZnO nanoarray as a working electrode was constructed and assembled. The nanoporous NiO/ZnO nanoarray film with a three‐dimensional structure was prepared on indium tin oxide (ITO) glass substrate through a two‐step route that combined chemical bath deposition method with a hydrothermal method. The nanoporous NiO/ZnO nanoarray electrode reveals a noticeable improvement in electrochromism compared with that of nanoporous NiO alone, including higher optical modulation (81 %), higher coloration efficiency (78.5 cm2 C−1), faster response times (2.6 and 9.7 s for coloring and bleaching, respectively), and favorable durability performance. Such enhancements are mainly attributed to the three‐dimensional structures of nanoporous NiO coated on ZnO nanoarray, namely, 1) the uniform hexagonal ZnO nanoarray loads more nanoporous NiO, 2) nanoporous NiO cross‐linked with ZnO nanorods provides a loose interspace morphology, 3) stronger adhesion between ZnO nanorods and ITO covered with ZnO seed, 4) core–shell and cross‐linked structures promote electrolyte infiltration, and 5) appropriate band gaps improve charge transfer.
Methoden zur Bewertung experimenteller Ergebnisse bei kleinem Stichprobenumfang

Published: December 2018

AbstractFür die Bewertung der Standsicherheit bestehender Bauteile oder Bauwerke bedarf es häufig Informationen, die nur durch eine Bestandserfassung oder ‐beprobung gewonnen werden können. Die integralste Form der experimentellen Bewertung im Bestand stellt der klassische Belastungsversuch dar, da so direkt und zerstörungsfrei die Tragsicherheit nachgewiesen werden kann. Problematisch ist allerdings die Übertragung der Ergebnisse eines oder weniger durchgeführter Versuche auf andere, nicht beprobte Bauteile. Dieser Beitrag diskutiert existierende Bewertungsmethoden und stellt einen neuen Ansatz für die Berücksichtigung der Unsicherheiten bei der Übertragung von Versuchsergebnissen auf nicht direkt beprobte Bauteile vor.
Testing strategy in phase 3 trials with multiple doses
Authors: Li Jianjun (David) , Kirby Simon 
Published: December 2018

AbstractIn this paper, we consider multiplicity testing approaches mainly for phase 3 trials with two doses. We review a few available approaches and propose some new ones. The doses selected for phase 3 usually have the same or a similar efficacy profile, so they have some degree of consistency in efficacy. We review the Hochberg procedure, the Bonferroni procedure, and a few consistency‐adjusted procedures, and suggest new ones by applying the available procedures to the pooled dose and the high dose, the dose that is thought to be more efficacious between two doses. The reason behind the idea is that the pooled dose and the high dose are more consistent than the original two doses if the high dose is more efficacious than the low dose. We compare all approaches via simulations and recommend using a procedure combining 4A and the pooling approach. We also discuss briefly the testing strategy for trials with more than two doses.
Experimental measurements of bubble size distributions in a water model and its influence on the aluminum kinetics degassing

Published: December 2018

ABSTRACTAn experimental study of the gas‐liquid dynamics in a water model of an aluminum ladle was conducted. The rotor degassing performance was evaluated for two commercial rotor‐injector devices compared to a new rotor design. In this work, the influence of the turbulent properties of the flow fields on the bubble size distribution is analyzed for a better understanding of its impact on the degassing efficiency in aluminum refinement operations. The degassing process was analyzed by two different methods: (a) a high‐speed camera was used to obtain the bubble size distribution into the container; and (b) the particle image velocimetry technique (PIV) was employed to obtain the liquid flow properties. It was found that the rotor geometry plays an important role on the average size and distribution of the bubbles. The energy dissipation rate contours show significant differences for the distinct rotors tested. These hydrodynamic states and bubbles distribution dominate the kinetic and efficiency of the degassing processes. It was shown that the new rotor configuration enhances the degassing kinetics, due to a more suitable bubble dispersion compared to the commercial rotors tested.
A Scaffold‐Hopping Strategy toward the Identification of Inhibitors of Cyclin G Associated Kinase

Published: December 2018

AbstractWe recently reported the discovery of isothiazolo[4,3‐b]pyridine‐based inhibitors of cyclin G associated kinase (GAK) displaying low nanomolar binding affinity for GAK and demonstrating broad‐spectrum antiviral activity. To come up with novel core structures that act as GAK inhibitors, a scaffold‐hopping approach was applied starting from two different isothiazolo[4,3‐b]pyridines. In total, 13 novel 5,6‐ and 6,6‐fused bicyclic heteroaromatic scaffolds were synthesized. Four of them displayed GAK affinity with Kd values in the low micromolar range that can serve as chemical starting points for the discovery of GAK inhibitors based on a different scaffold.
