Published: May 2018

AbstractThe foodservice industry is a highly competitive branch where customer satisfaction and loyalty is dependent on the price and the quality of the food. To improve cost competitiveness, instead of fresh ingredients, more preprocessed items are used as components in dishes. This may impair the perceived product quality, and thus potentially decrease customer satisfaction. The effects of the component quality on a single dish were tested by serving fish soup in a consumer study (n = 205), and by serving the dish to an in‐house panel (n = 17) using a modified check‐all‐that‐apply method. The variable used for the quality of the fish and vegetable components was a previously unprocessed/fresh component being compared to a processed. This study showed that in a modular dish, each component had an effect on the perceived quality of the dish. When replacing a preprocessed component with a fresh one, the perceived pleasantness increased to a higher level. The fish as the main dish component had the largest effect on the quality. Fresh fish has the ability to enhance the taste of soup, even with frozen vegetables. The results from this study indicate that the effect of freshness can also be perceived in the cooked product.

AbstractObjectiveTo determine the risk of endometrial neoplasia in relation to endometrial thickness and to evaluate factors influencing endometrial thickness in reproductive‐aged Thai women with polycystic ovary syndrome (PCOS).MethodsThe present cross‐sectional study was done at the Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand, between October 1, 2010, and January 31, 2013. We recruited women (aged ≥18 years) with PCOS diagnosed according to the revised 2003 Rotterdam criteria. Data were collected for physical examinations, pelvic ultrasonography, hormonal profiles, and carbohydrate metabolic profiles. Endometrial tissue was obtained using a disposable endometrial‐suctioning device.ResultsThe final analysis included 122 women. Six (4.9%) patients had endometrial neoplasia. All six women had an endometrial thickness of 7 mm or more, representing a risk of 8.7% (6/69) in this group. The endometrial thickness was significantly but weakly associated with body mass index (r=0.227, P=0.012), 2‐hour blood glucose (r=0.323, P=0.001), fasting glucose to insulin ratio (r=0.185, P=0.042), homeostatic model assessment of insulin resistance (r=0.183, P=0.044), and free testosterone (r=0.236, P=0.009). No categorical risk factors for an endometrial thickness of 7 mm or more were identified.ConclusionThai women with PCOS and a thick endometrium (≥7 mm) had an 8.7% risk of endometrial neoplasia. Invasive endometrial surveillance for the prevention of endometrial cancer is recommended in these women.
Blunt traumatic great saphenous vein pseudoaneurysm

Published: May 2018

AbstractTraumatic venous pseudoaneurysm is extremely rare. Only two cases of great saphenous venous (GSV) pseudoaneurysm have been reported. We present a case in which a gradually enlarged mass occurred at the calf after local injury. It was nonpulsatile and varied in size with posture. It was initially misdiagnosed by contrast MRI. Duplex ultrasound and surgical intervention eventually identified it as a GSV pseudoaneurysm. This case demonstrates the need for physicians to consider venous pseudoaneurysm as a possible diagnosis for nonpulsatile masses in patient with traumatic history, and to use Duplex ultrasound for adequate evaluation.

AbstractBackgroundTo assess the association between HLA‐B57.01 (Human leukocyte antigen) and clinical parameters of chronic periodontitis in people living with HIV (PLWHIV).MethodsAll patients were recruited from the HIVCENTER at the University Hospital Frankfurt during April 2014 and July 2015. Periodontal examination included Periodontal Screening Index (PSI), Gingivalindex (GI), Bleeding on Probing Index (BOP), Periodontal Probing Depth (PD), Clinical Attachment Level (CAL) and DMF‐T Score (decayed, missing, filled teeth). Associations among periodontitis, HLA‐system and additional risk factors in PLWHIV were evaluated in multivariate analyses.ResultsOne hundred PLWHIV were enrolled. Forty‐five patients were naive, meaning that these patients never took antiretroviral (ARV) drugs before, 55 patients treated with combined antiretroviral therapy (cART). Nineteen patients presented a positive HLA‐B 57.01 status. PLWHIV who were carriers of HLA‐B 57.01 had significantly lower PSI‐scores (Grade 3 or higher; 0/19 [0%] versus 16/41 [39%] versus 17/40 [42%];p = < 0.001), GI‐scores (Grade 2 or higher; 0/19 [0%] versus 19/41 [46%] versus 28/40 [70%];p = < 0.001) and BOP‐Scores (2/19 [1%] versus 38/41 [92%] versus 40/40 [100%];p = < 0.001) in comparison to naive PLWHIV and PLWHIV receiving cART, who were both not carriers of HLA‐B 57.01. A lower value of PSI‐, GI‐ and BOP‐Score is associated with improved periodontal health. The adjusted odds ratio (OR) of periodontitis was decreased in patients who were carriers of HLA‐B 57.01 by measurement of PSI‐Score (OR = 0.006, 95% confidence interval (CI) = 0.001 to 0.026), GI‐Score (OR = 0.018, 95% confidence interval (CI) = 0.003 to 0.104) and BOP‐Score (OR = 0.003, 95% confidence interval (CI) = < 0.001 to 0.011).ConclusionsHLA‐B 57.01 is an independent resistance indicator for generalized periodontitis in PLWHIV with respect to established cofactors.

AbstractInjected chemical flooding systems with high salinity tolerance and fast‐dissolving performance are specially required for enhancing oil recovery in offshore oilfields. In this work, a new type of viscoelastic‐surfactant (VES) solution, which meets these criteria, was prepared by simply mixing the zwitterionic surfactant N‐hexadecyl‐N,N‐dimethyl‐3‐ammonio‐1‐propane sulfonate (HDPS) or N‐octyldecyl‐N,N‐dimethyl‐3‐ammonio‐1‐propane sulfonate (ODPS) with anionic surfactants such as sodium dodecyl sulfate (SDS). Various properties of the surfactant system, including viscoelasticity, dissolution properties, reduction of oil/water interfacial tension (IFT), and oil‐displacement efficiency of the mixed surfactant system, have been studied systematically. A rheology study proves that at high salinity, 0.73 wt.% HDPS/SDS‐ and 0.39 wt.% ODPS/SDS‐mixed surfactant systems formed worm‐like micelles with viscosity reaching 42.3 and 23.8 mPa s at a shear rate of 6 s−1, respectively. Additionally, the HDPS/SDS and ODPS/SDS surfactant mixtures also exhibit a fast‐dissolving property (dissolution time <25 min) in brine. More importantly, those surfactant mixtures can significantly reduce the IFT of oil–water interfaces. As an example, the minimum of dynamic‐IFT (IFTmin) could reach 1.17 × 10−2 mN m−1 between the Bohai Oilfield crude oil and 0.39 wt.% ODPS/SDS solution. Another interesting finding is that polyelectrolytes such as sodium of polyepoxysuccinic acid can be used as a regulator for adjusting IFTmin to an ultralow level (<10−2 mN m−1). Taking advantage of the mobility control and reducing the oil/water IFT of those surfactant mixtures, the VES flooding demonstrates excellent oil‐displacement efficiency, which is close to that of polymer/surfactant flooding or polymer/surfactant/alkali flooding. Our work provides a new type of VES flooding system with excellent performances for chemical flooding in offshore oilfields.

Published: May 2018

ABSTRACTIntroduction: In this study we compared the electrodiagnostic (EDX) yield of limb muscles in revealing lower motor neuron (LMN) dysfunction by electromyography (EMG) in early‐stage amyotrophic lateral sclerosis (ALS). Methods: This investigation was undertaken as a retrospective review at a single center. Results: Our study included 122 consecutive patients with possible ALS, as defined by revised El Escorial criteria. Distal limb muscles showed more frequent EMG abnormalities than proximal muscles. EDX yield was found to be higher in the limb where weakness began and when clinical signs of LMN dysfunction were evident. Adoption of the Awaji criteria significantly increased the yield of EMG‐positive segments in the cervical (P < 0.0005) and lumbosacral (P < 0.0001) regions, and upgraded 19 patients into the probable category and 1 patient into the definite category. Discussion: EMG abnormalities are predominant in the distal limb in early‐stage ALS. A redefinition of an EDX‐positive cervical or lumbosacral segment, with an emphasis on distal limb muscles, may result in an earlier ALS diagnosis. Muscle Nerve 58: 389–395, 2018
Mutated cancer autoantigen implicated cause of paraneoplastic myasthenia gravis
Authors: Zekeridou Anastasia , Griesmann Guy E. , Lennon Vanda A. 
Published: May 2018

ABSTRACTIntroduction: Antitumor immune responses are postulated to initiate paraneoplastic neurological disorders when proteins that are normally restricted to neural cells are expressed as oncoproteins. Mutated oncopeptides could bypass self‐tolerant T cells to activate cytotoxic effector T lymphocytes and requisite helper T lymphocytes to stimulate autoantibody production by B lymphocytes. Methods: We investigated muscle‐type nicotinic acetylcholine receptor (AChR) antigen expression at transcriptional and protein levels in a small‐cell lung cancer line (SCLC) established from a patient with AChR‐immunoglobulin G (IgG)‐positive myasthenia gravis. Results: We identified messenger RNA transcripts encoding the 2 AChR α1‐subunit isoforms and 7 alternative‐splicing products, 3 of which yielded premature stop codons. Despite detecting native muscle‐type AChR pentamers in the tumor, we did not identify mutant α1‐peptides. However, we found α1‐subunit‐derived peptides bound to tumor major histocompatibility complex (MHC)1‐protein. In a control SCLC from an antineuronal nuclear autoantibody, type 1 (anti‐Hu)‐IgG‐positive patient, we identified MHC1‐complexed Hu protein‐derived peptides but not AChR peptides. Discussion: Our findings support onconeural protein products as pertinent immunogens initiating paraneoplastic neurological autoimmunity. Muscle Nerve 58: 600–604, 2018

Published: May 2018

The main aim of this article is to assess Provincial intervention outcomes in Makana Local Municipality, identify factors, which cause unsuccessful Provincial intervention, and lastly, measure the extent to which these factors played a role during intervention in Makana Local Municipality. Provincial interventions have been granted a legal and constitutional status by South African Constitution, Section 100 – 139 and 216. Therefore, Provincial interventions have been used to assist municipalities that are failing to achieve their constitutional mandate as a result of multiple issues, such as, financial instability, corruption, maladministration, poor leadership and management, and political tensions. Interventions by the Province are therefore meant to find long‐term solutions to the problems municipalities find themselves in. It is against this background that this article assess the outcomes of the Provincial intervention in Makana Local Municipality. The research utilized a qualitative approach in a form of documentary sources and open‐ended interviews with a range of actors in Makana Local Municipality. The study found that Provincial intervention in Makana has resulted to some extent successful outcomes; however, there are still areas needing further improvements in the municipality as evident by the current state of the municipality.The key findings of the study include an increase of 8 million in Revenue Collection, the development of a clear, firm Creditor Payment Procedure, and the recruitment process to start filling up critical positions; further to this, Makana received a qualified audit opinion in 2015; in addition, the municipality is honoring the Creditors' debt repayment plans in accordance. This is the presentation of findings on the outcomes of Provincial intervention in Makana Municipality. The article concludes by providing lessons for both the Province and Local government for effective interventions.
A role for two‐component signaling elements in the Arabidopsis growth recovery response to ethylene

Published: May 2018

AbstractPrevious studies indicate that the ability of Arabidopsis seedlings to recover normal growth following an ethylene treatment involves histidine kinase activity of the ethylene receptors. As histidine kinases can function as inputs for a two‐component signaling system, we examined loss‐of‐function mutants involving two‐component signaling elements. We find that mutants of phosphotransfer proteins and type‐B response regulators exhibit a defect in their ethylene growth recovery response similar to that found with the loss‐of‐function ethylene receptor mutant etr1‐7. The ability of two‐component signaling elements to regulate the growth recovery response to ethylene functions independently from their well‐characterized role in cytokinin signaling, based on the analysis of cytokinin receptor mutants as well as following chemical inhibition of cytokinin biosynthesis. Histidine kinase activity of the receptor ETR1 also facilitates growth recovery in the ethylene hypersensitive response, which is characterized by a transient decrease in growth rate when seedlings are treated continuously with a low dose of ethylene; however, this response was found to operate independently of the type‐B response regulators. These results indicate that histidine kinase activity of the ethylene receptor ETR1 performs two independent functions: (a) regulating the growth recovery to ethylene through a two‐component signaling system involving phosphotransfer proteins and type‐B response regulators and (b) regulating the hypersensitive response to ethylene in a type‐B response regulator independent manner.
Nano Co3O4 as Anode Material for Li–Ion and Na‐Ion Batteries: An Insight into Surface Morphology
Authors: Subalakshmi Palani , Sivashanmugam Arumugam 
Published: May 2018

AbstractCo3O4 is regarded as a competent anode material for lithium and sodium ion batteries having high theoretical capacity of 890 mAh g‐1 obtained through metal displacement reaction with Li or Na. Nano Co3O4 consisting of 20–30 nm‐sized particles was synthesized through a simple precipitation method and characterized through X‐ray diffraction, Fourier‐transform infrared spectroscopy, scanning electron microscopy, Transmission electron microscopy and X‐ray photoelectron spectroscopy. Electrochemical evaluation of the nano Co3O4 as anode material for Li‐ion and Na‐ion batteries was performed through cyclic voltammetry, electrochemical impedance spectroscopy and charge‐discharge cycling studies. Nano Co3O4 delivered high discharge capacity of 423 mAh g‐1 at 0.1 C even after 40 cycles as Li‐ion battery anode and exhibited stable discharge behaviour up to 130 cycles with high rate capability. Nano Co3O4 in Na‐ion configuration delivered discharge capacity of 101 mAh g‐1 at 0.1 C rate even after 30 cycles. At higher current rates Co3O4 electrodes exhibited severe capacity fading due to the huge volume change occurred during sodiation / desodiation. Ex‐situ SEM and elemental analyses evidenced that disintegration of electrode structure resulting from volume change and continuous decomposition of electrolyte were responsible for the poor electrochemical performance of Co3O4 with Na+ ions while in Li‐ion configuration nano Co3O4 outshined in cycling performance.

Published: May 2018

AbstractFree standing electrodes have grabbed attention among the researchers around the globe due to its ease of fabrication, scale‐up and flexibility for stack development. In the present communication, we have described a novel approach to improve the areal capacitance of graphite fiber paper (GP) from 4.5 ×10−3 F cm−2 to 0.677 F cm−2 by surface modification. Surface functionalised graphite paper (Oxd‐GP) and its chemically reduced counterpart (Red‐GP) are explored as electrode materials for supercapacitors. The materials synthesized are structurally characterized by X‐ray diffraction (XRD), Raman spectroscopy, X‐ray photoelectron spectroscopy (XPS), Energy dispersive analysis of X‐rays (EDAX) and field emission scanning electron microscopy (FESEM). The electrochemical performance of the electrodes is assessed using cyclic voltammetry (CV), galvanostatic charge‐discharge (GC) analysis and electrochemical impedance spectroscopy (EIS) where both Oxd‐GP and Red‐GP exhibit appreciable areal capacitance while Red‐GP shows excellent cycle life over 2600 cycles. Red‐GP showed an increment in capacitance over 1000 cycles while attaining stability. This work suggests that modified graphite paper can be a low‐cost and free‐standing electrode for high performance energy storage devices.

AbstractPb(OAc)4 to assist N−N bond formation via dehydrogenative cyclization of hydrazide‐hydrazones to generate the pyridazinones as bioactive molecules have been described. All the products were well characterized by various spectroscopic analyses. Furthermore, the structure of (E)‐3a,7‐diethyl‐6‐((thiophen‐2‐ylmethylene)amino)‐1,2,3a,4‐tetrahydro‐3‐oxa‐6,6a‐diazafluoranthen‐5(6H)‐one was unambiguously conformed by single crystal X‐ray analysis. The in vitro biological evaluation revealed that several of these compounds exhibited greater cytotoxic potency than that of doxorubicin drug. (E)‐N′‐(4‐chlorobenzylidene)‐2‐(1,8‐diethyl‐1,3,4,9‐tetrahydropyrano[3,4‐b]indol‐1‐yl)acetohydrazide exhibited most cytotoxic activity against both A549 and PC3 cancer cell lines with IC50 values of 1.77±0.08 and 1.88±0.33 μM, respectively.
Triboelectric Nanogenerator Based on Biocompatible and Easily Available Polymer Films

Published: May 2018

AbstractWe have fabricated robust triboelectric nanogenerators (TENGs) employing different polymer films which are biocompatible and easily available. The combination of polyurethane and PTFE layers is seen to provide the highest TENG parameters with an open circuit peak‐to‐peak output voltage of ∼33.5 V and a current value of 27.4 μA with a gentle tapping force of 0.33 N. The topography of the film surface has been characterized using atomic force microscopy in conjunction with image analysis. We find a very good, albeit non‐linear, correlation between the TENG electrical output and the surface roughness. Our studies do not support any relation between the permittivity of the medium and the TENG output. Employing cellulose acetate and Kapton as the triboelectric layers, we have constructed a simple force sensor, whose output is seen to be highly linear over a large range of force varying from 0.24 to 5.2 N, and a significantly high output of 1.5 V/N.
Spurious mode distinguish by modal response contribution index in eigensystem realization algorithm

Published: May 2018

SummaryModal identification process has played an important role for civil engineering structures. Among the identification methods, eigensystem realization algorithm is one of the most popular one. However, the noises in practical environment can influent the effectiveness of eigensystem realization algorithm, which can introduce spurious modes due to the overestimated physical order for the structure. This paper proposes a new index named the modal response contribution index (MRCI) for the eigensystem realization algorithm, which can determine the structural physical order and then distinguish spurious mode more precisely. First, the structural responses are divided into different modal response by the well‐known modal superposition theory. Then the square root summation of each modal response is obtained and named as MRCI. A modified stabilization diagram is also presented, which increases the row number of Hankel matrix with the determined order by MRCI. The straight lines formed by the stable points in the modified stabilization diagram designate the structural modal parameters. Finally, one numerical example and the monitoring data of a practical cable‐stayed bridge are employed. The results show that the proposed MRCI and modified stabilization diagram can identify the structural physical mode more precisely.
