AbstractTropospheric O3 has been decreasing across much of the eastern U.S. but has remained steady or even increased in some western regions. Recent increases in VOC and NOx emissions associated with the production of oil and natural gas (O&NG) may contribute to this trend in some areas. The Northern Front Range of Colorado has regularly exceeded O3 air quality standards during summertime in recent years. This region has VOC emissions from a rapidly developing O&NG basin and low concentrations of biogenic VOC in close proximity to urban‐Denver NOx emissions. Here VOC OH reactivity (OHR), O3 production efficiency (OPE), and an observationally constrained box model are used to quantify the influence of O&NG emissions on regional summertime O3 production. Analyses are based on measurements acquired over two summers at a central location within the Northern Front Range that lies between major regional O&NG and urban emission sectors. Observational analyses suggest that mixing obscures any OPE differences in air primarily influenced by O&NG or urban emission sector. The box model confirms relatively modest OPE differences that are within the uncertainties of the field observations. Box model results also indicate that maximum O3 at the measurement location is sensitive to changes in NOx mixing ratio but also responsive to O&NG VOC reductions. Combined, these analyses show that O&NG alkanes contribute over 80% to the observed carbon mixing ratio, roughly 50% to the regional VOC OHR, and approximately 20% to regional photochemical O3 production.

AbstractWe investigated a broadband communication system for high‐speed vehicles such as airplane in which the millimeter wave band (40 GHz band) facilitates broadband wireless communications. Some developments and evaluations toward such the realization have been conducted. This paper introduces examples and results of the efforts to realize high‐speed mobile communication systems that take advantage of the features of the millimeter wave band along with overcoming the challenges associated with high‐frequency band development.
Cu nanoparticles/PVC Composites: Thermal, Rheological, and Antibacterial Properties
Authors: Miranda Cristian , Rodríguez‐Llamazares Saddys , Castaño Johanna , Mondaca María Angélica 
Published: July 2016

AbstractThe effect of Cu nanoparticle (NP) content (0.3–3.0 wt%) on antibacterial, thermal, and rheological properties of PVC composites prepared by melt blending method was investigated. The composites were characterized by scanning electron microscopy (SEM) with energy dispersive X‐ray spectroscopy (EDX), transmission electron microscopy (TEM), capillary rheology, thermogravimetric analysis (TGA), and inductively coupled plasma atomic emission spectroscopy (ICP‐OES). A homogeneous distribution of copper on the composite surface was observed by SEM‐EDX. TEM images of Cu NPs/PVC composite films showed well‐dispersed and distributed Cu NPs and microparticles in the PVC matrix, but the size of particles increased with increasing copper content. The shear thinning and power law behavior was observed for all samples. At low shear rates (100 s−1) apparent viscosity of composites with copper loading lower than 1.2 wt% exhibited a “ball bearing” effect. The Cu particles enhanced the thermal stability of Cu NPs/PVC composites compared with neat PVC. The release of copper ions from Cu NPs/PVC composite films into the aqueous medium was negligible after 6 h of immersion. Polymer films with Cu NP amount higher than 0.6 wt% showed a similar kinetics of bacterial growth; therefore, a substantial improvement of antimicrobial activity was not observed with increasing Cu NP content.

Published: July 2016

AbstractObjectiveThe main objective of this study was to evaluate the effect of the ADIPOQ rs2241766, LEP rs7799039, and FTO rs9939609 polymorphisms on the birth weight status of Brazilian infants.MethodsThis cross‐sectional study was conducted in southern Brazil. Large for gestational age (LGA) newborns (n = 105), and the same number of small for gestational age/adequate for gestational age newborns, were included. Genotyping of the rs2241766, rs7799039, and rs9939609 polymorphisms was done by PCR‐RFLP analysis. Logistic regression was used to investigate the association between LGA newborns and the presence of the polymorphisms.ResultsInfants carrying the GG genotype of the rs7799039 polymorphism were 2.12 times more likely to be born LGA than those carrying the GA + AA genotypes (95% CI: 1.17–3.83). These results did not change substantially after adjusting for potential confounding variables (OR = 1.98; 95% CI 1.05–3.73) and adjustment for the three polymorphisms (OR = 1.98; 95% CI 1.05‐3.74). Regarding the ADIPOQ polymorphism, newborns carrying the TG or GG genotype were 1.88 times more likely to be born LGA than those carrying the TT genotype, although this difference was not statistically significant (p = 0.082). No association was found between the FTO gene polymorphism and newborn weight status.ConclusionsThis study showed that the GG genotype of the LEP polymorphism rs7799039 is a risk factor for LGA infants. The exact role and mechanism of action of the GG genotype of this polymorphism in weight status control remain to be elucidated, and more studies are needed.
Potential arms race in the coevolution of primates and angiosperms: brazzein sweet proteins and gorilla taste receptors

Published: July 2016

AbstractObjectivesWe explored whether variation in the sweet taste receptor protein T1R3 in primates could contribute to differences in sweet taste repertoire among species, potentially reflecting coevolution with local plants. Specifically, we examined which primates are likely to be sweet “tasters” of brazzein, a protein found in the fruit of the African plant Pentadiplandra brazzeana that tastes intensely sweet to humans, but provides little energy. Sweet proteins like brazzein are thought to mimic the taste of sugars to entice seed dispersers. We examined the evolution of T1R3 and assessed whether primates are likely “deceived” by such biochemical mimicry.MethodsUsing published and new sequence data for TAS1R3, we characterized 57 primates and other mammals at the two amino acid sites necessary to taste brazzein to determine which species are tasters. We further used dN/dS‐based methods to look for statistical evidence of accelerated evolution in this protein across primate lineages.ResultsThe taster genotype is shared across most catarrhines, suggesting that most African primates can be “tricked” into eating and dispersing P. brazzeana's seeds for little caloric gain. Western gorillas (Gorilla gorilla), however, exhibit derived mutations at the two brazzein‐critical positions, and although fruit is a substantial portion of the western gorilla diet, they have not been observed to eat P. brazzeana. Our analyses of protein evolution found no signature of positive selection on TAS1R3 along the gorilla lineage.DiscussionWe propose that the gorilla‐specific mutations at the TAS1R3 locus encoding T1R3 could be a counter‐adaptation to the false sweet signal of brazzein.
Replication of laser‐textured alumina surfaces by polydimethylsiloxane: Improvement of surface hydrophobicity
Authors: Yilbas Bekir Sami , Yousaf M. Rizwan , Ali H. , Al‐Aqeeli N. 
Published: July 2016

ABSTRACTAlumina tiles are textured by a laser beam to obtain improved hydrophobic characteristics at the surfaces. Since the textured surfaces are optically opaque, the resulting surfaces are copied and replicated by polydimethylsiloxane (PDMS). Some of the texture features such as whiskers‐like structures with complex shapes could not be copied by PDMS and synthesized silica particles are deposited onto PDMS copied and replicated surfaces to create a lotus effect. Analytical tools are incorporated to characterize the PDMS copied and replicated surfaces as well as synthesized silica particles deposited surfaces. Dynamic water contact angle measurements are carried out to assess hydrophobic characteristics of the resulting surfaces. It is found that PDMS copied and replicated surfaces have almost identical surface texture morphology to that of laser treated surface. Introducing synthesized silica particles improved the lotus effect on the PDMS copied and replicated surfaces; in which case, the hysteresis of droplet contact angle remains significantly low. © 2016 Wiley Periodicals, Inc.

A comparative study to predict the interphase modulus in polymer nanocomposites
Authors: Zare Yasser 
Published: July 2016

ABSTRACTIn this study, the interphase modulus (Ei) in polymer nanocomposites is calculated by two methods and the calculated results are compared at different conditions. In the first method, the experimental moduli of samples are applied to Ji model and suitable “Ei” is calculated. In the second method, a multilayered interphase is considered, in which the Young's moduli of layers (Ek) depend to the distance between the nanoparticle surface and the polymer matrix by power function of “Y” parameter. The “Ei” is calculated for multilayered interphase assuming the same and different layer thicknesses (tk) by Parallel and Series models. Finally, the “Ei” values calculated by the explained methods are compared for two reported samples. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44076.
Fabrication of super‐ductile PP/LDPE blended parts with a chemical blowing agent
Authors: Zhou Ying‐Guo , Su Bei , Turng Lih‐Sheng 
Published: July 2016

ABSTRACTThe mechanical blending of polypropylene (PP) and low density polyethylene (LDPE) is an economical and simple method for producing new polymeric materials for specific applications. However, the reduction in strain‐at‐break of the blend is one of its main shortcomings. In this study, PP/LDPE foamed parts were fabricated by conventional injection molding (CIM) with azodicarbonamide as a chemical blowing agent (CBA) and tested for tensile properties at two test speeds. Also, the fracture surfaces of the parts were investigated by scanning electron microscopy (SEM). In addition, to investigate the underlying mechanism of the super‐ductility, the tested samples were carefully analyzed and compared, and further characterized by differential scanning calorimetry and SEM. The results suggest that fabricating PP/LDPE super‐ductile parts using CIM with a CBA is feasible. The results also indicate that there is a close relationship between the mechanical properties and morphological structures, which are deeply influenced by the dosage of CBA, the PP/LDPE ratio, and the packing parameters. Furthermore, compared to conventional injection molded solid parts, the ductility of the foamed parts can be dramatically improved by the formation of microfibrils in the PP phase, which come into being under certain processing conditions. © 2016 Wiley Periodicals, Inc.

Solvent‐free synthesis of chiral molecularly imprinted polymers: Porosity control using a nano‐sized solid porogen
Authors: Duarte Mariana , Billing Johan , Yilmaz Ecevit 
Published: July 2016

ABSTRACTMolecularly imprinted polymers (MIPs) have been synthesized in the absence of a solvent using fumed silica nanoparticles to create a porous network. The method employed led to a chiral imprinting effect and allowed for an excellent control over the internal morphology of imprinted and non‐imprinted polymer (NIP) materials. The polymers possess high surface areas (>300 m2) and identical pore size (112 Å). The MIP exhibited an imprinting factor (IF) of 9 and a selectivity value (α) of 1.83 for (−)‐ephedrine. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44104.
Covidien micro vascular plug in congenital heart diseases and vascular anomalies: A new kid on the block for premature babies and older patients
Authors: Boudjemline Younes 
Published: July 2016

ObjectivesTo evaluate the safety, feasibility, and efficacy of the MVP™ microvascular plug(Covidien) for closure of vascular anomalies in patients with congenital heart diseases (CHD).BackgroundThe MVP™ is a novel device with PTFE integrated. The device has been recently introduced in the radiological field and reported exclusively for neurological anomalies. Methods: All CHD patients receiving the device from April 2015 until July 2015 were included in the study and followed up clinically as well as by transthoracic echocardiography. Standard safety and follow‐up such as vascular complications, embolization rate, and residual shunting were assessed.ResultsTwelve patients with a median age of 2.6‐years (0.03–12.6 years) and a mean weight of 13 kg (2.8–34.2 kg) were included. Devices were delivered from the femoral artery in 10 and from the femoral vein in 2 patients. Devices were used for closure of patent ductus arteriosus (PDA) closure (n = 5), aorto‐pulmonary collaterals or Blalock–Taussig shunt (n = 5), veno‐venous fistula (n = 1), and coronary fistula (n = 1). One device was retrieved before release due to inappropriate size estimation (PDA spasm). The PDA was successfully closed using a PDA device (Lifetech, Medtronic). Immediate angiographic evaluation showed minimal or no shunt in 90% (10/11 patients) and 100% occlusion rate after a mean follow‐up of 3.2‐months. There was no device embolization, hemolysis, or any other complication following closure.ConclusionsThe delivery of new MVP™ micro vascular plug system (Covidien) is safe and effective in patients with CHD for closure of a variety of vascular abnormalities. The low profile of the device and the sheathless nature of the procedure make it particularly interesting for PDA closure in premature babies. © 2016 Wiley Periodicals, Inc.
Understanding responses to materials and colors in interiors
Authors: Ulusoy Begüm , Nilgün Olguntürk 
Published: July 2016

AbstractThis article investigates the free associations of materials and colors in the context of interior architecture. Materials and colors rarely appear alone in interiors; therefore, in the scope of this study, the researchers explored material pairs and color pairs in addition to single materials and single colors. To elicit free associations from these interior design elements, 192 randomly selected volunteers participated in an experiment using a group of material (fabric, timber, plasterboard) and color (red, green, white) models under controlled conditions. The results contribute to an increased understanding of the associations between the concepts of materials and colors in interiors. While, each model was associated with sensory descriptors, only some models were associated with symbolic or affective descriptors. Single materials were related to different descriptors in interiors on their own, but when they were paired they were associated with fewer affective descriptors. The results showed that color pairs were always associated with all types of descriptors with an exception of red and green color pair, which was not mentioned with affective descriptors. The study findings are expected to be beneficial for interior architects, architects, product designers and researchers who want to shape and investigate a user's experience of interiors. © 2016 Wiley Periodicals, Inc.

Serum asymmetric dimethylarginine and arginine levels predict microvascular and macrovascular complications in type 2 diabetes mellitus
Authors: Ganz Tali , Wainstein Julio , Gilad Suzan , Limor Rona , Boaz Mona , Stern Naftali 
Published: July 2016

AbstractBackgroundIncreased oxidative stress in diabetes increases nitric oxide (NO) oxidation and low l‐arginine (Arg) could further reduce NO and impair vascular function, thereby accelerating, in the long run, vascular complications. We therefore measured Arg and asymmetric dimethylarginine (ADMA) levels in patients with type 2 diabetes mellitus (T2DM) and healthy controls. Additionally, we observed the diabetic individuals over time to see if Arg and asymmetric dimethylarginine predicted T2DM complications.MethodsWe examined baseline serum Arg and ADMA levels in a cohort of 105 participants with type 2 diabetes and compared them with an age‐ and weight‐matched nondiabetic group of 137 individuals who served as a reference population. Additionally, we assessed whether Arg and/or ADMA predicted macrovascular and microvascular complications over 6 years of follow‐up.ResultsSerum Arg was lower in individuals with T2DM than in controls (64 ± 28 vs 75 ± 31 μmol/L; P = .009) and inversely related to hemoglobin A1c (r = −0.2; P = .002). Over follow‐up, we observed that participants with T2DM in the lowest quartile of Arg had increased risk for the subsequent evolution of nephropathy, peripheral neuropathy, and composite microvascular complications (odds ratio [OR] = 5.5; 95% confidence interval [CI] −1.9 to 16; P = .002). The highest ADMA quartile was associated with increased risk for both microvascular (OR = 4.5; 95% CI −1.4 to 14.1; P = .009) and 6.5‐year incident macrovascular complications (OR = 8.3; 95% CI 1.9‐35.5; P = .004).Conclusionl‐Arginine levels are lower in individuals with T2DM than in matched controls. Both low Arg and high ADMA, independent of each other and adjusted for classical risk factors, predict the incidence of microvascular complications.
A scalable software framework for data integration in bioprocess development
Authors: Schmid Ingrid , Aschoff Joachim 
Published: July 2016

AbstractEffectiveness in lab workflows—despite progresses made in automation and lab informatics—is often hindered by insufficient integration of devices and data. The iLAB software framework, a middleware connecting and integrating devices and data, provides a plugin architecture that can be adapted to individual lab environments. Integration of devices is preferably based on standardized data and communication protocols. In addition to device integration, process data and result data from different sources (e.g. readers) are converted to a standard format and administered by a powerful database for further processing. In this paper, the use of iLAB in a bioprocess development application is described. Process parameters and measured values of two high‐throughput bioreactor systems (96‐well plates and 10 mL reactor vessels) are collected in the iLAB database. Data from screening experiments and offline data are visualized, analyzed, and compared. A filter algorithm allows searching for matching parameters in experiments as well as the comparison of correlated datasets, independently from the used bioreactor system. The database model enables the consolidation of data, the transition from data to information, and a solid base for management decisions on enterprise level.

AbstractBackgroundWe evaluated the impact of radiation, reconstruction, and timing of tracheoesophageal puncture (TEP) on complications and speech outcomes.MethodsRetrospective review identified 145 patients who underwent TEP between 2003 and 2007.ResultsNinety‐nine patients (68%) had primary and 46 (32%) had secondary TEP, with complications occurring in 65% and 61%, respectively (p = .96). Twenty‐nine patients (20%) had major complications (18 primary and 11 secondary; p = .42). Ninety‐four patients (65%) had pre‐TEP radiation, 39 (27%) post‐TEP radiation, and 12 (8%) no radiation. With patients grouped by TEP timing and radiation history, there was no difference in complications, fluency, or TEP use. With mean 4.7‐year follow‐up, 82% primary and 85% secondary used TEP for primary communication (p = .66). Free‐flap patients used TEP more commonly for primary communication after secondary versus primary TEP (90% vs 50%; p = .02).ConclusionPrimary and secondary tracheoesophageal speakers experience similar high rates of complications. Extent of pharyngeal reconstruction, rather than radiation, may be more important in selection of TEP timing. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1765–1771, 2016

AbstractPurposeThis report describes initiation of apheresis capability in Liberia, Africa to support a clinical trial of convalescent plasma therapy for Ebola Virus Disease.MethodsA bloodmobile was outfitted in the United States as a four‐bed apheresis unit with capabilities including pathogen reduction, electronic blood establishment computer system, designated areas for donor counseling and laboratory testing, and onboard electrical power generation. After air transport to Liberia, the bloodmobile was positioned at ELWA Hospital, Monrovia, and connected to the hospital's power grid. Liberian staff were trained to conduct donor screening, which included questionnaire and onsite blood typing and transfusion transmitted infection (TTI) testing, and plasma collection and processing.ResultsThe bloodmobile was operational within 3 weeks after arrival of the advance team. Of 101 donors who passed the pre‐screening questionnaire, 32 were deferred. Twenty‐eight of ninty‐nine tested survivors were deferred for positive transfusion transmitted infection (TTI) tests; twenty‐one were positive for hepatitis B, hepatitis C, or human immunodeficiency virus. The majority of donors had type O blood; all but one were Rh positive. Forty‐three survivors donated at least once; eighty‐nine apheresis attempts resulted in eighty‐one successful collections.ConclusionsApheresis capability was emergently established in Liberia to support an efficacy trial of Ebola Convalescent Plasma. Extensive cooperation among multinational team members, engineers, logisticians, and blood safety technical personnel at the operational site was required to surmount challenges to execution posed by logistical factors. The high proportion of positive TTI tests supported the use of a pathogen reduction system to enhance product safety. J. Clin. Apheresis 32:175–181, 2017. © 2016 Wiley Periodicals, Inc.
