Published: December 2015

AbstractIn this work, a separation strategy for fructose purification from high‐fructose corn syrup (HFCS) was established, involving two consecutive instances of chromatography with Ca2+‐immobilized cation exchanger XA 2004/22. Among the 14 calcium ion form of strong acid cation exchangers tested, cation exchanger XA 2004/22 displayed the best adsorption performances for fructose, with the adsorption ratio of fructose to glucose reaching 2.32 at 303 K. The static equilibrium adsorption data of fructose on Ca2+‐immobilized cation exchanger XA 2004/22 closely fitted the linear equation, and the adsorption kinetic followed the pseudo‐second order model. Close agreement between the theoretical curves and the experimental breakthrough data was observed using the Thomas and Yoon‐Nelson models. Under the optimized conditions, fructose was prepared at a purity of 0.924 g/g (92.4 mass %) and 0.243 g/g (24.3 mass %) yield by two‐step packed bed chromatography with Ca2+‐immobilized cation exchanger XA 2004/22. Further introducing one step of simple cooling crystallization gave crystalline fructose at 0.99 g/g (99 mass %) purity.
Impact of carbon nanotubes on the toxicity of inorganic arsenic [AS(III) and AS(V)] to Daphnia magna: The role of certain arsenic species
Authors: Wang Xinghao , Qu Ruijuan , Allam Ahmed A. , Ajarem Jamaan , Wei Zhongbo , Wang Zuoyao 
Published: December 2015

Abstract

As a type of emerging nanomaterial, hydroxylated multiwalled carbon nanotubes (OH-MWCNTs) may interact with other pollutants in the aquatic environments and further influence their toxicity, transport, and fate. Thus, evaluation of toxicity to arsenic in the presence of CNTs needs to receive much more attention. The present study was conducted to explore the underlying mechanisms of OH-MWCNT-induced arsenic (As[III] and As[V]) toxicity changes in the aquatic organism Daphnia magna at different pH levels. The most toxic species for As(III) and As(V) to D. magna were found to be H2AsO3− and H2AsO4−. It appeared that the pH values were of greatest importance when the biological toxicity of As(III) and As(V) was compared. Furthermore, the effects of OH-MWCNTs on arsenic toxicity to D. magna indicated that the presence of OH-MWCNTs could enhance the toxicity of arsenic. The interactions of arsenic with OH-MWCNTs were further investigated by conducting adsorption experiments. The adsorption capacity of As(V) by OH-MWCNTs was found to be higher than that of As(III). To conclude, adsorption of certain arsenic species onto OH-MWCNTs is crucial for a reliable interpretation of enhanced toxicity. Environ Toxicol Chem 2016;35:1852–1859. © 2016 SETAC
Plasma cholinesterase activity as a biomarker for quantifying exposure of green sturgeon to carbaryl following applications to control burrowing shrimp in Washington State
Authors: Troiano Alexandra T. , Grue Christian E. 
Published: December 2015

Abstract

Willapa Bay (Washington State, USA) has been 1 of the rare intertidal locations where large-scale pesticide applications occur. Until recently, carbaryl was applied to control burrowing shrimp that decrease commercial oyster productivity. The bay is a critical habitat for green sturgeon (Acipenser medirostris), an anadromous species listed as threatened under the US Endangered Species Act. However, the hazard that carbaryl poses is unknown. Surrogate seawater-acclimated white sturgeon (A. transmontanus) were exposed to 0 μg L−1, 30 μg L−1, 100 μg L−1, 300 μg L−1, 1000 μg L−1, and 3000 μg L−1 carbaryl for 6 h, and brain acetylcholinesterase (AChE) and plasma butyrylcholinesterase (BChE) activities were measured. Enzyme recovery was measured in an additional cohort exposed to 1000 μg L−1 carbaryl for 6 h. Activity of AChE was reduced (p ≤ 0.001) at concentrations ≥ 100 μg L−1 with recovery in the 1000 μg L−1 cohort by 72 h. Surprisingly, BChE activity was greater than controls at concentrations ≥ 300 μg L−1 (p &gt; 0.05), a finding confirmed in additional fish exposed to 3000 μg L−1 for 6 h (+30%, p &lt; 0.001) with apparent recovery by 48 h. Plasma samples were collected from free-living green sturgeon before and 4 d to 5 d after application of carbaryl in Willapa Bay. Activity of BChE after application was reduced 28% (p &lt; 0.001), indicating exposure to the pesticide. However, the lack of congruence between BChE and AChE activity in captive white sturgeon exposed to carbaryl indicates that further studies are needed to better understand the risk carbaryl exposure poses to green sturgeon.

Reliable cooperative scheme for public safety services in LTE‐A networks
Authors: Munir Daniyal , Gu Jaheon , Hasan Syed Faraz , Chung Min Young 
Published: December 2015

AbstractIn order to enable effective public safety services in challenged environments, 3rd Generation Partnership Program is considering the use of device‐to‐device (D2D) communications. D2D communications can be ideal in various emergency situations where the conventional network services get suspended. We propose a D2D‐based user equipment (UE) relaying process to support the out‐of‐range isolated UEs. The main idea is to allow UEs that have active connections with eNB to exchange data with the isolated UEs over direct D2D links. This paper proposes a mechanism that enables an ordinary UE to serve as a relay for the isolated UEs, considering the D2D link capacity and the relay's radial velocity. We define the complete procedure of establishing a reliable relay link between UEs in public safety environments and analyse its performance. Copyright © 2015 John Wiley & Sons, Ltd.

Published: December 2015

BackgroundThe 10/66 Dementia Research Group developed and validated a culture and education fair battery of cognitive tests for diagnosis of dementia in population‐based studies in low‐income and middle‐income countries including India.AimsThis study examined the association between individual domains of the 10/66 battery of cognitive tests and ‘disability’ and ‘functional impairment’ in community‐dwelling older adults in South India.MethodsOne hundred twenty‐nine adults aged 60–90 years residing in Karunapura, in the city of Mysore, were interviewed in their own homes. Cognitive functioning was measured by administering the 10/66 battery of cognitive tests that composes of Community Screening Instrument for Dementia (CSI'D' COGSCORE), verbal fluency (VF) and word list memory recall (WLMR). A reliable informant was interviewed to ascertain if the subject's cognitive problems have resulted in functional impairment. Disability was measured by WHO Disability Schedule‐II (DAS).ResultsThe women had significantly lower CSI'D' COGSCORE score when compared with men (p = 0.002). The presence of ‘functional impairment’ resulting from cognitive decline was significantly associated with lower scores on VF (p = 0.03), WLMR (p = 0.03) and CSI'D' COGSCOREs (p < 0.01). There was a significant inverse association between WHO DAS II score and WLMR (p = 0.004), VF (0.006) and CSI'D' COGSCORE scores (p ≤ 0.001) even after adjusting for self‐reported ischaemic heart disease, stroke, chronic obstructive airway disease, hypertension and diabetes.ConclusionsLower scores on individual domains of the 10/66 battery of cognitive tests are associated with higher levels of disability and functional impairment in community‐dwelling older adults. These culture and education fair tests are suitable for use in population‐based research in India. Copyright © 2015 John Wiley & Sons, Ltd.
Behavior, preferences, and willingness to pay for measures aimed at preventing pollution by pharmaceuticals and personal care products in China
Authors: Wang Xiaowen , Howley Peter , Boxall Alistair BA , Rudd Murray A 
Published: December 2015

Abstract
The release of pharmaceuticals and personal care products (PPCPs) into the environment has been held up as a potential threat to ecosystem and human health. Using a custom-designed survey of residents living in Xiamen, China, this paper examines individuals' disposal practices, awareness of the environmental impact of PPCPs, and willingness to pay for measures aimed at reducing the likelihood of PPCPs being released into the environment. The vast majority of respondents report that they dispose of PPCPs through the thrash. The results of a contingent valuation experiment suggest a substantial willingness to pay (WTP) for policy measures aimed at reducing PPCP pollution. Income as well as subjective perceptions relating to overall financial health, expenditure on PPCPs, and overall concern with environmental issues emerged as significant predictors of respondents' WTP. Our results should be of interest to policymakers looking for ways to mitigate the introduction of PPCPs in the environment. Integr Environ Assess Manag 2016;12:793–800. © 2015 SETAC
Diphtheria Toxin- and GFP-Based Mouse Models of Acquired Hypoparathyroidism and Treatment With a Long-Acting Parathyroid Hormone Analog
Authors: Bi Ruiye , Fan Yi , Lauter Kelly , Hu Jing , Watanabe Tomoyuki , Cradock Jim , Yuan Quan , Gardella Thomas , Mannstadt Michael 
Published: December 2015

ABSTRACT

Hypoparathyroidism (HP) arises most commonly from parathyroid (PT) gland damage associated with neck surgery, and is typically treated with oral calcium and active vitamin D. Such treatment effectively increases levels of serum calcium (sCa), but also brings risk of hypercalciuria and renal damage. There is thus considerable interest in using PTH or PTH analogs to treat HP. To facilitate study of this disease and the assessment of new treatment options, we developed two mouse models of acquired HP, and used them to assess efficacy of PTH(1–34) as well as a long-acting PTH analog (LA-PTH) in regulating blood calcium levels. In one model, we used PTHcre-iDTR mice in which the diphtheria toxin (DT) receptor (DTR) is selectively expressed in PT glands, such that systemic DT administration selectively ablates parathyroid cells. For the second model, we generated GFP-PT mice in which green fluorescent protein (GFP) is selectively expressed in PT cells, such that parathyroidectomy (PTX) is facilitated by green fluorescence of the PT glands. In the PTHcre-iDTR mice, DT injection (2 × 5 μg/kg, i.p.) resulted in moderate yet consistent reductions in serum PTH and sCa levels. The more severe hypoparathyroid phenotype was observed in GFP-PT mice following GFP-guided PTX surgery. In each model, a single subcutaneous injection of LA-PTH increased sCa levels more effectively and for a longer duration (&gt;24 hours) than did a 10-fold higher dose of PTH(1–34), without causing excessive urinary calcium excretion. These new mouse models thus faithfully replicate two degrees of acquired HP, moderate and severe, and may be useful for assessing potential new modes of therapy. © 2015 American Society for Bone and Mineral Research.

ABSTRACTWe aimed at evaluating the effect of titanium (Ti) with nanotopography (Nano) on the endogenous expression of BMP‐2 and BMP‐4 and the relevance of this process to the nanotopography‐induced osteoblast differentiation. MC3T3‐E1 cells were grown on Nano and machined (Machined) Ti surfaces and the endogenous BMP‐2/4 expression and the effect of BMP receptor BMPR1A silencing in both osteoblast differentiation and expression of genes related to TGF‐β/BMP signaling were evaluated. Nano supported higher BMP‐2 gene and protein expression and upregulated the osteoblast differentiation compared with Machined Ti surface. The BMPR1A silencing inhibited the osteogenic potential induced by Nano Ti surface as indicated by reduced alkaline phosphatase (ALP), osteocalcin and RUNX2 gene expression, RUNX2 protein expression and ALP activity. In addition, the expression of genes related to TGF‐β/BMP signaling was deeply affected by BMPR1A‐silenced cells grown on Nano Ti surface. In conclusion, we have demonstrated for the first time that nanotopography induces osteoblast differentiation, at least in part, by upregulating the endogenous production of BMP‐2 and modulating BMP signaling pathway.

Knowledge based response correction method for design of reconfigurable N‐shaped microstrip patch antenna using inverse ANNs
Authors: Aoad Ashrf , Simsek Murat , Aydin Zafer 
Published: December 2015

SummaryArtificial neural networks (ANNs) have been often used for engineering design problems. In this work, an inverse model of a reconfigurable N‐shaped microstrip patch antenna which is formed by ANN is considered to find design parameters. For this task, knowledge‐based response correction consists of two steps, which include generating response using multilayer perceptron as a first step and correcting this response using knowledge based methods such as source difference, prior knowledge input, and prior knowledge input with difference as a second step. The proposed antenna has four states of operation controlled by two Positive‐Intrinsic‐Negative (PIN) diodes with ON/OFF states. The two‐step ANN models are inversely trained using the optimum of the resonant frequency parameter as the input and the physical dimensions of the proposed antenna as outputs of the multilayer perceptron. The outputs and, in some methods, the input parameters of the multilayer perceptron are sent as input to the knowledge‐based models while the obtained outputs from the two steps are the results of the new physical dimensions of the redesigned reconfigurable antenna that will be compared and analyzed. This input/output complexity of the proposed reconfigurable antenna allows an accurate and fast inverse model to be developed with less training data. Users may use this antenna and its ANN models to develop new products in the market where any frequency in the operating region can be given to the input to result an appropriate form of the new reconfigurable antenna.
