Biogenic Synthesis of Silver Nanoparticles with High Antimicrobial and Catalytic Activities using Sheng Di Huang (Rehmannia glutinosa)

Field: Chemistry (Physical Sciences)

Silver nanoparticles (AgNPs) are widely sought after for a variety of biomedical and environmental applications due to their antimicrobial and catalytic properties. We present here a green and simple synthesis of AgNPs utilizing traditional Chinese medicinal herbs. The screening of 20 aqueous herb extracts shows that Sheng Di Huang (Rehmannia glutinosa) had the most promising potential in producing AgNPs of 30±6 nm, with narrow size distribution and high crystallinity. The antimicrobial activities of these AgNPs conducted on E. coli cells were found to be superior in comparison to poly(vinylpyrrolidone)-capped AgNPs synthesized using common chemical method. Additionally, the AgNPs obtained possess excellent catalytic performance in the reduction of 4-nitrophenol to 4-aminophenol. We compared the phytochemical and FTIR spectral analyses of the herb extract before and after synthesis, in order to elucidate the phytochemicals responsible for the reduction of Ag+ ions and the capping of the AgNPs produced.
2162-8769/2014/3(9)/Q3045/5/$31.00 © The Electrochemical Society JSS FOCUS ISSUE ON OXIDE THIN FILM TRANSISTORS Role of Self-Assembled Monolayers on Improved Electrical Stability of Amorphous In-Ga-Zn-O Thin-Film Transistors

Field: Materials Science (Physical Sciences)

Self-assembled monolayers (SAMs) have been used to improve both the positive and negative bias-stress stability of amorphous indium gallium zinc oxide (IGZO) bottom gate thin film transistors (TFTs). N-hexylphosphonic acid (HPA) and fluorinated hexylphos-phonic acid (FPA) SAMs adsorbed on IGZO back channel surfaces were shown to significantly reduce bias-stress turn-on voltage shifts compared to IGZO back channel surfaces with no SAMs. FPA was found to have a lower surface energy and lower packing density than HPA, as well as lower bias-stress turn-on voltage shifts. The improved stability of IGZO TFTs with SAMs can be primarily attributed to a reduction in molecular adsorption of contaminants on the IGZO back channel surface and minimal trapping states present with phosphonic acid binding to the IGZO surface.
Role of thioredoxin system in regulation of neural stem cell proliferation and differentiation

Field: Neuroscience (Life Sciences)

Neural precursor cells (NPCs) have been a hot research topic because of their regenerative potentials. These cells maintain a remarkable capacity for continuous neurogenesis throughout the life and therefore have inspired the quest for a cure towards central nervous system (CNS) repair, however their clinical application is severely restricted due to their limited proliferation. The role of Thioredoxin-1 as a neuroprotective antioxidant protein has been shown previously. This multifaceted protein has also been linked to increase in NPCs proliferation. For my MSc thesis, I hypothesized that enhancing Trx1 levels using a novel intracellular protein delivery approach may enhance cell proliferation and alter differentiation of NPCs. Using immunocytochemistry and Western blotting, I showed that Trx promotes cell proliferation and potentiates oligodendrogenesis in these cells. I have also examined downstream signaling mechanisms involved in these processes. My studies indicate that Trx therapy may represent a viable approach for induction of NPCs proliferation.
Exploring ADS-B as an Alternative Data Source for Flight Data Monitoring of General Aviation

Field: Engineering (Physical Sciences)

Flight data monitoring (FDM) is believed to be effective for mitigating risks of aviation accidents by the International Civil Aviation Organization (ICAO) and major airlines who implemented flight data monitoring programs.In the United States, flight data monitoring is recommended by the Federal Aviation Administration (FAA) as a voluntary safety program, namely the flight operational quality assurance (FOQA) program.However, implementing a FDM program not only requires an expensive investment on technological equipment, but also involves long-term labor costs to regularly collect and analyze flight data after flights are completed.Especially for general aviation (GA), implementation of a FDM program using on-board flight data recorder equipment may be too expensive for some owners or operators.Automatic Dependent Surveillance Broadcast Out (ADS-B Out) is a precise satellite-based surveillance system which can continually broadcast flight data.The broadcasted flight data can be received by other nearby ADS-B In capable aircraft or ground-based ADS-B receivers.This paper explores the ADS-B as an alternative data source of FDM for GA.First, the structure and content of flight data broadcast by ADS-B Out are analyzed.Then, based on the basic flight parameters, additional flight parameters are derived, and flight metrics are developed from the standpoint of flight operation analysts.Finally, the potential of ADS-B for supporting FDM is discussed.
Modelling of hydrostatic bearings for servo-cylinders

Field: Engineering (Physical Sciences)

Hydraulic servo cylinders are widely used in versatile industrial applications such as machine tools, industrial robots, autonomous manufacturing systems and special applications in laboratories. To reduce friction and allow smooth and controllable displacement of the actuator, hydrostatic journal bearings are used at the ends of the rod. The design and manufacturing of this elements is challenging since the good operation relays on the very small tolerances required to bear the load on the cylinder and to reduce leakages. In this work, a virtual design and test tool for hydrostatic journal bearing with pockets, developed in OpenModelica environment, is presented. The influence of eccentricity and manufacturing tolerances is then studied and discussed. The model proposed has the aim to explore the extreme and critical operating conditions of the servo-cylinder and to help and/or improve the design phase.
The Case of a 44-Year-Old Survivor of Unrepaired Tetralogy of Fallot, Right Aortic Arch and Abdominal Aortopulmonary Collateral Vessels

Field: Medicine (Health Sciences)

The most common congenital cyanotic heart disease is described in the literature as the Tetralogy of Fallot. This abnormality is characterized by the presence of ventricular septal defect (VSD), obstruction of the right ventricular (RV) outflow tract, right ventricular hypertrophy, and overriding aorta. In patients with pulmonary atresia with ventricular septal defect (PA/VSD), major aortopulmonary collateral arteries (MAPCA) are common; however, although some of them do not have PA/VSD, they do have other particular anatomical variants. The case we are presenting in this article is a rare mild symptomatic adult noncorrected TOF, with preserved RV function, right aortic arch, and MAPCAs (“classic” thoracic MAPCAs but also abdominal MAPCAs). The anatomy of a complex congenital defect is well illustrated by cardiac magnetic resonance (CMR) and computer tomography angiography (CTA), and these imaging techniques are mostly used to understand the relative clinical “silence” TOF. Imaging scans thus play a key role in the evaluation of these patients, being very important to know the indications and limitations of each method, but also to learn to combine them with each other depending on the clinical picture of the patient’s presentation. Additionally, the close collaboration between clinicians and imagers is essential for a correct, complete and detailed preoperative evaluation, being subsequently essential for cardiovascular surgeons, the whole team thus deciding the best therapeutic management.
[Clinical evaluation of natural coral implantation in osseous periodontal defects. Results after one year].

Field: Dentistry (Health Sciences)

17 intrabony periodontal defects on 14 patients were surgically treated by a alloplastic graft using micro-granules of natural coral. Criteria of evaluation were standardized probing and reproducible radiographs. The measures, made at day 0 and one year post-implantation showed a reduction in probing pocket depth (4.38 mm +/- 0.43) assessed more through a gain of clinical attachment (3.38 mm +/-0.30) than an increase of the gingival recession (1.00 mm +/- 0.20). These results are statistically significant.

Time Domain Analysis of Suspension Bridge Flutter Based on State Space

Field: Engineering (Physical Sciences)

Flutter of suspension bridge is an aerodynamic instability phenomenon that occurs due to interactions between wind and structural vibration, which is an issue in the wind-resistant design of long-span suspension bridges. Equations of motion for the flutter vibration of suspension bridges are established in time domain, and then these equations of motion are transformed into state space. By introducing the precise integration method, flutter equations are solved in time domain, the critical flutter velocity and displacement time history of suspension bridge are obtained. Finally, the method presented in this paper is verified using a numerical example, the analytical results were compared with the wind tunnel test, it showed that the flutter analysis results are in good agreement with the results of wind-tunnel test. Compared to conventional flutter analysis in frequency domain, the advantage of the method presented in this paper is that there is only one variable of wind speed in flutter analysis in time domain.

Separated Families and Child Support Policies in Times of Social Change: A Comparative Analysis

Field: Social Sciences (Social Sciences)

Abstract Child support policies aim to ensure separated parents continue to pay for the upkeep of their children until they reach adulthood. This is a laudable aim, often related to alleviating poverty in single parent families following relationship breakdown. There is a long policy history of this in most Western countries, but the institutional and operational challenges are considerable as policies try to keep pace with changes in family relationships, household structures, and gendered patterns of employment and childcare. Tracking changes in parents’ earning and caring responsibilities therefore matter in determining child support liabilities. The question is, how well are child support systems doing in adapting to social changes and norms of gender equality? To answer that, this chapter presents an analysis of the latest data from a comparative study of 15 countries using national informants’ accounts of the key policy principles and operational features of their child support systems.
Detection of Aspergillus fumigatus Antigen in Sera and Urine of Rats with Experimental Recurrent Pulmonary Aspergillosis.

Field: Immunology and Microbiology (Life Sciences)

A new rat model of recurrent pulmonary aspergillosis using cyclophosphamide (CPM) for re-institution of immunosuppression was established. The recurrence induced by CPM was rapid and pulmonary lesions were uniform in all animals. It is therefore considered to be a good model for evaluation of the mechanisms of recurrence and methods of early diagnosis by antigen detection in sera and urine. Galactomannan antigen of aspergilli in sera was examined by PASTOREX Aspergillus, and a very low positive rate was observed instead of the of severe pulmonary infection confirmed by histopathological study. However, antigen in urine detected by immunoblotting showed a relatively high positive rate from the early stage of the recurrence. Based on these findings, it can be concluded that the recognition of antigenuria is useful for early diagnosis of Aspergillus infection.
Enhancing the effectiveness of administrative support for learning and teaching using workplace projects in lower-income countries

Field: Social Sciences (Social Sciences)

Middle-level administrators in African universities are often under-utilised in terms of their contribution to the administrative support for learning and teaching. They also have little access to professional development. This paper presents the findings of a study to develop a programme to enable these administrators to enhance their support for learning and teaching in their institutions. Following a selection process based on their own universities and programme workshop sessions, participants carry out projects to 'make a difference' to administrative effectiveness. Analysis of project reports and participant interviews shows that the projects had a real impact, and this remains ongoing in many cases. The programme design is evaluated, and key elements highlighted: a locally based selection process; international accreditation; a strength-based approach and authentic assessment involving a workplace project and reflection on learning. Educators who work in similar 'lower-income country' contexts may find it constructive to make comparisons with their own experiences.
Towards a common European approach for energy labelling and assessment of existing dwellings

Field: Energy (Physical Sciences)

Energy performance assessment and energy labelling of existing buildings is being introduced in most of the EU Member States. The new European Directive on Energy Performance of Buildings will probably support this trend in the future. Furthermore the Directive also prescribes common rules and contents for the future energy assessment procedures. Will this lead to a more common approach of energy assessment in existing buildings and what country or region specific elements are necessary to implement successful local programmes? Starting from a comparison of energy labelling and assessment schemes in different EU Member States (recent SAVE project), it is demonstrated how common elements (e.g. parts in calculation procedures, training of energy experts,…) and country specific items (types of dwellings, financial support schemes,…) should be linked to achieve an effective local approach. In Belgium, a research group has been working with support of the Belgian government for the last 5 years towards an effective Belgian programme for the introduction of energy assessment. This programme, including the technical approach, financial support, training schemes, etc., is explained as an example how to integrate common and country specific elements.
A non-intrusive screening methodology for environmental hazard assessment at waste disposal sites for water resources protection

Field: Environmental Science (Physical Sciences)

The environmental and health risks posed by unregulated waste disposal sites are potential concerns of Pacific Rim regions and island ares because of the need to protect aquifers and other valuable water resources. A non-intrusive screening methodology to determine site characteristics including possible soil and/or groundwater contamination, areal extent of waste, etc. is being developed and tested at waste disposal sites in Nebraska. This type of methodology would be beneficial to Pacific Rim regions in investigating and/or locating unknown or poorly documented contamination areas for hazard assessment and groundwater protection. Traditional assessment methods are generally expensive, time consuming, and potentially exacerbate the problem. Ideally, a quick and inexpensive assessment method to reliably characterize these sites is desired. Electromagnetic (EM) conductivity surveying and soil-vapor sampling techniques, combined with innovative three-dimensional geostatistical methods are used to map the data to develop a site characterization of the subsurface and to aid in tracking any contaminant plumes. The EM data is analyzed to determine/estimate the extent and volume of waste and/or leachate. Soil-vapor data are analyzed to estimate a site`s volatile organic compound (VOC) emission rate to the atmosphere. The combined information could then be incorporated as one part of an overall hazard assessmentmore » system.« less
Single-Agent Oral Vinorelbine in the Treatment of Pediatric Progressive Optic Pathway Glioma: A Single Institutional Experience

Field: Medicine (Health Sciences)

Purpose: The vinca alkaloids’ activity against pediatric low-grade glioma (PLGG) is well established. The goal of the present study is to describe our experience with oral vinorelbine in patients with progressive optic pathway glioma (OPG), not only regarding the clinical response, but also the cost benefit using an oral medication. Methods: Patients under 21 years of age with unresectable and/or progressive OPG were eligible. Oral vinorelbine was administered at a dose of 90mg/m2 daily on days 0, 8 and 22, in a scheme of 4 weekly cycles for a total of 18 cycles (54 doses). Results: From 2013 to 2018, sixteen patients were enrolled onto the study, with a median age of 9,1 years (range 4,6-17,8y). The most common histology was pilocytic astrocytoma (88,8%). Best response to chemotherapy was reviewed with a response rate (complete, partial, or minor response) of 30% for the patients treated exclusively with the oral drug. Five-year event-free survival (EFS) rate was 43.4%. Six patients had to change to intravenous vinorelbine due to gastrointestinal toxicity, vomiting grade III. None of the patients showed neurotoxicity. The total cost including drug acquisition, administration and toxicity management was lower with the oral formulation comparing to IV one. Conclusion: Single-agent oral vinorelbine seems to have some clinical activity in the management of recurrent or refractory pediatric OPG, being an interesting and cost-effective option, minding that gastrointestinal toxicity may be limiting and a combination of antiemetics should be considered in this treatment regimen.
Migrating Love or What's Love Got to Do With It?: Transcultural Love and Sex Relations in French Caribbean Literary Texts

Field: Arts and Humanities (Social Sciences)

The foundations of the sociocultural and geopolitical community that is called the French Caribbean are clearly linked to experiences of migration. The moments and movements of this migration have been accompanied by multiple metissages that have created complexities of identity formulations. While so many French Caribbean sociocultural movements and texts acknowledge the importance of the phenomena of migration and metissage (for instance, Negritude, Antilleanity, Creolity, Aime Cesaire's Cahier d'un retour au pays natal [Return to My Native Land], and Frantz Fanon's Peau noire masques blancs [Black Skin White Masks]), relatively few examine the physical, emotional, and social relationships that consummated the migration experiences and concretized metissage. This essay is part of a larger study in which I examine some of these migratory exchanges in the form of transcultural sexual relationships in novels by Mayotte Capecia, Maryse Conde, Simone Schwarz-Bart, Stephen Alexis, Rene Depestre, Dany Laferriere, and others, to see how these impact on formulations of national, cultural, gender, and racial identities. I also attempt an investigation into the significance of the treatment of this theme for the literature of the French Caribbean in the face of the alienating sociocultural and political conditions imposed by the colonial experience within which the literature has evolved.
Comparison of a Needle-Type and a Microdialysis Continuous Glucose Monitor in Type 1 Diabetic Patients

Field: Medicine (Health Sciences)

OBJECTIVE—We examined the reliability of two continuous glucose sensors in type 1 diabetic patients at night and during rapid glucose excursions and verified the hypothesized nocturnal hypoglycemic drift of the needle-type sensor (CGMSgold) and delay of the microdialysis sensor (GlucoDay). RESEARCH DESIGN AND METHODS—Blood was sampled overnight twice per hour in 13 patients. Rapid-acting insulin was given subcutaneously 30 min after breakfast. Sampling once per minute started 45 min after breakfast and 75 min after insulin injection for 30 min, with the aim of determining peak and nadir glucose values. Mean absolute differences (MADs) between sensor and blood glucose values were calculated. Sensor curves were modeled for all patients using linear regression. Horizontal and vertical shifts of sensor curves from the blood glucose curves were assessed. A vertical shift indicates sensor drift and a horizontal shift sensor delay. RESULTS—Drift was minimal in the needle-type and microdialysis sensors (−0.02 and −0.04 mmol/l). Mean ± SD delay was 7.1 ± 5.5 min for the microdialysis sensor (P &lt; 0.001). MAD was 15.0% for the needle-type sensor and 13.6% for the microdialysis sensor (P = 0.013). After correction for the 7-min delay, the microdialysis MAD improved to 11.7% (P &lt; 0.0001). CONCLUSIONS—The microdialysis sensor was more accurate than the needle-type sensor, with or without correction for a 7-min delay. In contrast to the previous version, the current needle-type sensor did not exhibit nocturnal hypoglycemic drift. Continuous subcutaneous glucose sensors are valuable adjunctive tools for glucose trend analyses. However, considering the large MADs, individual sensor values should be interpreted with caution.
