Synthesis and characterization of Ti-/Zr-diphenylpropanedione complexes and their application in the ring opening polymerization of Ɛ-caprolactone
Authors: GÖKALP Yagmur , KAYAN Asgar 
Published: September 2018

The purpose has been to achieve a controlled ring-opening polymerization of ɛ-caprolactone, resulting in polymers with desirable properties such as high molecular weight, low polydispersity index, and highly regio-/stereo regular forms. Therefore, it is important to synthesize single site or reduced number of active site metal alkoxide compounds as catalysts. Ti(IV)/Zr(IV) diphenylpropanedione complexes were synthesized by reactions of titanium or zirconium alkoxides with diphenylpropanedione (dion) ligand. The obtained complexes were characterized by nuclear magnetic resonance (1H-, 13C-NMR), high resolution mass (HRMS), Fourier transform infrared (FTIR) spectroscopies and elemental analysis. These compounds were tested as catalysts for the ring opening polymerization of Ɛ-caprolactone. The structure of poly-caprolactone (PCL) was analyzed by some spectroscopic techniques (NMR, FTIR) and gel permeation chromatography (GPC). In this work, all Ti-/Zr-complexes were effective over polymerization of Ɛ-caprolactone in solventless environment. Consequently, Ɛ-caprolactone polymers were obtained different average molecular weights between 7000-34000 Da with the PDI values of 1.14-1.60.

Published: September 2018

Background and Purpose:The functional, communicative, and critical health literacy (FCCHL) scale is widely used for assessing health literacy (HL) in people with chronic diseases, such as type 2 diabetes (T2DM). Despite related subscales, researchers continue to apply a consecutive modeling approach, treating the three subscales as independent. This article studies the psychometric characteristics of the FCCHL by applying multidimensional modeling approaches.Methods:Rasch modeling and confirmatory factor analyses were applied to responses (paper-and-pencil) from 386 adults with T2DM.Results:Using a six-point rating scale and a three-dimensional Rasch model, this study found that a 12-item version of the FCCHL reduced within-item bias and improved subscale reliability indexes.Conclusion:This study suggests a parsimonious 12-item version of the FCCHL. The data fit a three-dimensional Rasch model best.

Building Transformative Global Nursing Partnerships
Authors: Upvall Michele J. 
Published: September 2018

Background and Purpose:Global nursing is a relatively new term identifying nurses contributing to global health. While personally and professionally rewarding, global health projects present unique challenges to global nurses that impact partnerships. The aim of this article was to describe the role of global nursing, and focus on relational–cultural theory as the foundation of transformative partnerships.Methods:This article is based upon a review of literature related to global health and relational inquiry. Peer-reviewed papers and research articles published within the past 10 years were used to support this discussion. Publications considered to be classics in the field of relationship inquiry were also utilized.Results:Global nursing is a relatively recent conceptualization in describing the role of nursing. Global nursing practice based upon relational–cultural theory and mediated by cultural humility provides a strong foundation for the development of transformative global nursing partnerships.Implications for Practice:This article provides a theoretical foundation for global nurses practicing in local and global contexts with diverse populations. Nursing partnerships in both local and global contexts can be challenging to initiate and manage, but global nurses are responsible for creating partnerships which are ethically sound, based on theory, and transformative in nature. Cultural humility plays a central role in the ongoing process of disconnecting and re-connecting for transformational partnerships with individuals, communities, and other health-care providers.

Published: September 2018

Abstract
Stable performance is a technical problem in the completely autotrophic nitrogen removal over nitrite (CANON) process with one single stage, which needs to be addressed. In the current work, a laboratory-scale submerged aerated biological filter (SABF) with a 3-L working volume was introduced into the CANON process to enhance its stable performance for 290 days under the following conditions: temperature of 30 ± 1 °C and dissolved oxygen (DO) level of 0.2–0.8 mg·L−1. The results showed that the average ammonium nitrogen removal efficiencies (ANRE) and total nitrogen removal efficiencies (TNRE) were 97.4% and 75.7%, respectively. A 16S rRNA gene high-throughput sequencing technology confirmed the phyla Proteobacteria and Planctomycetes as the ammonium oxidizing bacteria (AOB) and anaerobic ammonia-oxidizing bacteria (AnAOB) of this CANON process with SABF, respectively. The major contributor to nitrogen removal was the genus Candidatus Brocadia, in Brocadiae. The aim is to present an effective strategy as a reference for the design of full-scale plant for the CANON process.
Start-up performance of anaerobic/aerobic/anoxic-sequencing batch reactor (SBR) augmented with denitrifying polyphosphate-accumulating organism (DPAO) and their gene analysis

Published: September 2018

Abstract
This paper was aimed at investigating the bio-augmentation performance of anaerobic/aerobic/anoxic-type sequencing batch reactor (SBR) during its start-up period by introducing a strain of denitrifying polyphosphate-accumulating organism (DPAO). Two SBR reactors were inoculated to study the start-up performance, with one for DPAO introduction and the other as the control specimen. A comparison, of microbial community diversity based on the reactor which obtained a better performance, was made between polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analyses encoded by 16S rRNA and functional genes (nirS, nirK). The results indicated that the introduction of DPAO had a positive effect on the biological system, including a reduction of the start-up period, the improvement of sludge characteristics and the removal efficiency of nutrients, especially for phosphorus. By comparing the phylogenetic relationship of 16S rRNA and functional genes (nirS, nirK) of the reactor augmented with DPAO, it could be found that the phylogenetic relationship of these genes were remarkably inconsistent with each other. Therefore, 16SrRNA should not be used to determine the microbial community diversity of functional bacteria which could accomplish denitrification, and gene nirK should not be neglected when determining functional bacteria.

Published: September 2018

AbstractTo study dynamic laws of ammonia nitrogen retention in a typical rural–urban fringe canal, NaBr was selected as a conservative tracer agent, and NH4Cl as an additive nutritive salt to conduct an instantaneously added tracer experiment outdoors. On this basis, tracer additions for spiralling curve characterisation (TASCC) method and nutritive spiral indexes were used for the quantitative depiction of retention dynamics of NH4+-N. The Michaelis–Menten (M-M) model was used to simulate absorption dynamic characteristics of NH4+-N. Results showed that the variation range of absorption length of NH4+-N under background concentration was 93.94–295.54 m with an average value of 177.41 m, the variation range of mass transfer coefficient was 0.16–0.38 mm/s with an average value of 0.26 mm/s, and the variation range of absorption rate was 0.16–0.38 mg/(m2⋅s) with an average value of 0.26 mg/(m2⋅s). The maximum absorption rate of NH4+-N obtained via M-M equation simulation was 0.59–1.38 mg/(m2⋅s), and the subsaturation constant was 1.10–5.03 mg/L. The variability of the dynamic absorption length, overall dynamic absorption rate, and overall dynamic mass transfer coefficient shown by NH4+-N within the range from background concentration to saturation concentration certified that TASCC could analyse the dynamic process of NH4+-N retention and absorption by the canal.

Published: September 2018

Objective: The study aimed to investigate exchangeable proton signals of Aβ proteins of the
brains of Alzheimer’s disease (AD) model mice by using a chemical exchange-sensitive spin-lock
(CESL) MR imaging technique.

Method:
Eight non-transgenic (Tg) mice (5 young and 3 old) and twelve Tg-APPswe/PSdE9 mice (5
young and 7 old) were used in this study. CESL Z-spectra were obtained by using two saturation powers,
which were ω1 = 25 Hz with TSL = 3.0 s and ω1 = 500 Hz with TSL = 150 ms, at 71 offsets with uneven
intervals between the offset frequencies at Ω = ±7.0 ppm at a 9.4-T animal MRI system. For Zspectrum
analyses, regions of interest (ROIs) were drawn in the cortex, hippocampus, and thalamus of
both hemispheres. Magnetization transfer ratio asymmetry (MTRasym) curves were obtained from the Zspectra.
The Mann-Whitney test was used to compare the MTRasym values between the Tg and non-Tg
mice for each offset frequency and for each ROI.

Results:
The water saturation width of the full Z-spectrum was narrow with the 25-Hz saturation power,
but relatively broad with the 500-Hz saturation power. With the 25-Hz CESL saturation power, most of
the MTRasym values were negative for 3.5-, 3.0-, 2.0-, and 0.9-ppm offset frequencies and the MTRasym
values were significantly different between the control and Tg groups only in the left thalamus region at
3.5 ppm offset (p=0.0487). The MTRasym values were -6% to -7% for both 3.5 and 3.0 ppm, but less than
-2% for both 2.0 and 0.9 ppm. With 500-Hz CESL saturation power, all the MTRasym values were positive
for the 3.5-, 3.0-, 2.0-, and 0.9-ppm offset frequencies and the MTRasym values were not significantly
different between the control and Tg groups at all ROIs and at all offset frequencies. However, a
trend towards a significant difference was observed between the control and Tg groups in the right cortex
at 3.5 ppm (p=0.0578). The MTRasym values were 6% to 9% for 3.5, 3.0, and 2.0 ppm, but less than
2% for 0.9 ppm.

Conclusion:
In an in-vivo AD model experiment, MTRasym values increased with the high saturation
power than with the low saturation power. The MTRasym values were not significantly different, except
in the left thalamus region at 3.5 ppm offset. The CESL technique should be further developed to enable
its application in the brain of patients with neurodegenerative diseases.

Background:Neurological disorders constitute a growing worldwide concern due to the progressive aging of the population and the risky behavior they represent. Herbal medicines have scientific relevance in the treatment of these pathologies. One of these substances, Astragaloside IV (AS-IV), is the main active compound present in the root of Astragalus membranaceus (Fisch.) Bge, a Chinese medicinal herb with neuroprotective properties.Objective:In the present study we performed a systematic review that sought to comprehend the neuroprotective effect presented by AS-IV in experimental models of neurological disorders.Methods:This study is a systematic review, where an electronic search in United States National Library of Medicine (PubMed), Science Direct, Cochrane Library, Scientific Electronic Library Online (SciELO), Scopus, Web of Science, Medline via Proquest and Periodicos Capes databases covering the years between 2007 and 2017, using “Astragaloside IV” and “Neurodegenerative diseases”; “Astragaloside IV” and “ Neurological disorders” as reference terms was made.Results:A total of 16 articles were identified, in which the efficacy of AS-IV was described in experimental models of Parkinson’s disease, Alzheimer’s disease, cerebral ischemia and autoimmune encephalomyelitis, by improving motor deficits and/or neurochemical activity, especially antioxidant systems, reducing inflammation and oxidative stress.Conclusion:The findings of the present study indicate that the administration of AS-IV can improve behavioral and neurochemical deficits largely due to its antioxidant, antiapoptotic and antiinflammatory properties, emerging as an alternative therapeutic approach for the treatment of neurological disorders.
New Er3+-substituted NiFe2O4 Nanoparticles and their Nano-heterostructures with Graphene for Visible Light-Driven Photo-catalysis and other Potential Applications

Published: September 2018

Background:
Spinel ferrites have great scientific and technological significance because of their easy
manufacturing, low cost and outstanding electrical and magnetic properties. Nickel ferrite nanoparticles are
ferromagnetic material with an inverse spinel structure. They show remarkable magnetic properties and hence
have a wide range of applications in magnetic storage devices, microwave devices, gas sensors, telecommunication,
drug delivery, catalysis and magnetic resonance imaging.

Objective:
The aim and objective of this research article is to study the relative effect of NiErxFe2-xO4 nanoparticles
and their composites with reduced graphene oxide (rGO) for the photocatalytic degradation reaction and
other physical parameters.

Method:
Rare earth Er3+ substituted NiErxFe2-xO4 nanoparticles were synthesized via the facile wet chemical
route. Six different compositions of NiErxFe2-xO4 with varied Er3+ contents such as (x) = 0.00, 0.005, 0.01, 0.015,
0.02 and 0.025 were selected for evaluation of the effect of Er3+ on various parameters of NiFe2O4 nanoparticles.
Reduced graphene oxide (rGO) was prepared by Hummer’s method and was characterized by UV-Visible spectroscopy,
X-ray powder diffraction and Raman spectroscopy. Nano-heterostructures of NiErxFe2-xO4 with rGO
were prepared by the ultra-sonication method.

Results:
X-ray powder diffraction (XRD) confirmed the spinel cubic structure of all the compositions of NiErx-
Fe2-xO4 nanoparticles. The photocatalytic degradation rate of methylene blue and congo red under visible light
irradiation was found faster in the presence of NiErxFe2-xO4-rGO nanocomposites as compared to bare nanoparticles.
It was also investigated that as the Er3+ contents were increased in NiErxFe2-xO4 nanoparticles, the dielectric
parameters were largely affected. The room temperature DC-resistivity measurements showed that the Er3+ contents
in NiFe2O4 are responsible for the increased electrical resistivity of ferrite particles. The electrochemical
impedance spectroscopic (EIS) analysis of NiErxFe2-xO4 nanoparticles and NiErxFe2-xO4-rGO nanocomposites
revealed that the ferrite particles possess low conductance as compared to the corresponding composites with
graphene.

Conclusion:
The data obtained from all these characterization techniques suggested the potential applications of
the NiErxFe2-xO4 nanoparticles and NiErxFe2-xO4-rGO nanocomposites for visible light driven photo-catalysis and
high-frequency devices fabrication.
