Published: May 2016

Graphene has proven to be a promising material for transparent flexible electronics.In this study, we report the development of a transfer and doping scheme of large‐area chemical vapour deposited (CVD) graphene. A technique to transfer the as‐grown material onto mechanically flexible and optically transparent polymeric substrates using an ultraviolet adhesive (UVA) is outlined, along with the temporal stability of the sheet resistance and optical transparency following chemical doping with various metal chlorides (MxClyThe sheet resistance (RS) and 550 nm optical transparency (%T550) of the transferred un‐doped graphene was 3.5 kΩ sq−1(±0.2 kΩ sq−1) and 84.1 % (±2.9 %), respectively. Doping with AuCl3showed a notable reduction inRSby some 71.4 % (to 0.93 kΩ sq−1) with a corresponding %T550of 77.0 %. After 200 h exposure to air at standard temperature and pressure, the increase inRSwas found to be negligible (ΔRSAuCl3=0.06 kΩ sq−1), indicating that, of the considered MxClyspecies, AuCl3doping offered the highest degree of time stability under ambient conditions. There appears a tendency of increasingRSwith time for the remaining metal chlorides studied. We attribute the observed temporal shift to desorption of molecular dopants. We find that desorption was most significant in RhCl3‐doped samples whereas, in contrast, after 200 h in ambient conditions, AuCl3‐doped graphene showed only marginal desorption. The results of this study demonstrate that chemical doping of UVA‐transferred graphene is a promising means for enhancing large‐area CVD graphene in order to realise a viable platform for next‐generation optically transparent and mechanically flexible electronics.
Folate‐Conjugated Polylactic Acid–Silica Hybrid Nanoparticles as Degradable Carriers for Targeted Drug Delivery, On‐Demand Release and Simultaneous Self‐Clearance
Authors: Ma Zhifang , Li Xiaolei , Jia Xiaodan , Bai Jing , Jiang Xiue
Published: May 2016

Improving the therapeutic efficacy of cancer chemotherapy and reducing the side effects in patients are appealing goals but represent critical challenges. In this work, a novel SiO2‐based nanocarrier coated with polylactic acid and folate has been fabricated to destroy tumors in vivo. Folic acid promotes the targeted intracellular delivery of drug molecules to cancer cells overexpressing the folate receptor for improving the efficacy of the therapy. The polylactic acid layer prevents the premature leakage of drug until the polylactic acid is degraded as a response to low pH and enzymes; this mechanism is designed for sustained and on‐demand drug release to prevent undesired side effects. Escape of the drug molecules then triggers decomposition of the SiO2 carrier, improving its elimination from the patient. The strategy of combining the engineering flexibility of inorganic nanocarriers with the stimuli‐responsive biodegradability of organic molecules will offer new directions in on‐demand and sustained drug release for chemotherapy.

Published: May 2016

The production of aromatic hydrocarbons from cellulose by zeolite‐catalyzed fast pyrolysis involves a complex reaction network sensitive to the zeolite structure, crystallinity, elemental composition, porosity, and acidity. The interplay of these parameters under the reaction conditions represents a major roadblock that has hampered significant improvement in catalyst design for over a decade. Here, we studied commercial and laboratory‐synthesized ZSM‐5 zeolites and combined data from 10 complementary characterization techniques in an attempt to identify parameters common to high‐performance catalysts. Crystallinity and framework aluminum site accessibility were found to be critical to achieve high aromatic yields. These findings enabled us to synthesize a ZSM‐5 catalyst with enhanced activity, which offers the highest aromatic hydrocarbon yield reported to date.
Joint scheduling and mapping in support of downlink fairness and spectral efficiency in ieee 802.16e OFDMA system

Published: May 2016

The next generation broadband wireless networks deploy orthogonal frequency division multiple access (OFDMA) as the enabling technologies for broadband data transmission with QoS capabilities. In such broadband wireless systems, one major issue is how to utilize radio resource efficiently while maintaining fairness between sessions as well as providing adequate QoS. In this work, we propose an approach for OFDMA/time division duplex (TDD) downlink suitable for IEEE802.16e WiMAX systems that combines scheduling and burst mapping algorithms for a trade‐off between session fairness, QoS, and spectral efficiency. While optimizing radio resources under QoS and fairness constraints is an NP‐hard problem, we follow a heuristic approach that simplifies the complexity of the algorithm. Performance results show that while the new scheme outperforms the Proportional Fair algorithm in terms of fairness, it also improves the overall system spectral efficiency.

Primary Malignant Melanoma of Pleura: A Case Report and Literature Review
Authors: Agarwal Poojan , Nambiyar Kaniyyapan , Manju Kaushal  , Bhardwaj Minakshi
Published: May 2016

Malignant melanoma is one of the most aggressive and treatment resistant skin cancers. India enjoys a low incidence of melanoma, and age specific incidence rates for cutaneous malignant melanoma (CMM) are being less than 0.5 per 1,000,000. This could be due to under‐reporting of melanoma on account of a low index of suspicion by clinicians and pathologists alike. Most common site for origin of primary melanoma is skin, accounting for about 91.2% of all reported primary malignant melanoma cases. Other primary sites are relatively uncommon. Primary pleural melanoma is a very rare tumor and to the best of our knowledge, only seven cases have been reported so far worldwide. We hereby discuss a new case, only second from India. Our patient also had coexistent congenital hairy nevus, an unusual association also noted in two previously reported cases. Excluding primary cutaneous melanoma with pleural metastasis was a diagnostic challenge in this case but multiple cutaneous biopsies together with clinical and findings helped us arrive at this unusual diagnosis. Unfortunately, the patient succumbed to his illness. Diagn. Cytopathol. 2016;44:648–652. © 2016 Wiley Periodicals, Inc.
Recognition and Quantification of Some Monoamines Neurotransmitters
Authors: Elmosallamy Mohamed A. F. , Saber Amr L.
Published: May 2016

Three neurotransmitter sensors for dopamine, serotonin, and epinephrine have been developed. Potentiometric sensors for serotonin and epinephrine are novel and first to be introduced. The neurotransmitter potentiometric sensors are based on using dibenzo‐30‐crown‐10 (DB30C10), dibenzo‐24‐crown‐8 (DB24C8), and dibenzo‐18‐crown‐6 (DB18C6) as ionophores and neutral carriers incorporating in poly(vinyl chloride) matrix membrane plasticized with o‐nitrophenyl octyl ether. Sensors based on dibenzo‐30‐crown‐10 show good responses for the dopamine, serotonin, and epinephrine (Type I–III, respectively) with a cationic slope of 57.9 mV decade−1 and detection limit of 4.0×10−5 mol L−1 dopamine, cationic slope of 55.9 mV decade−1 and detection limit of 4.0×10−5 mol L−1 serotonin, and cationic slope of 54.4 mV decade−1 and detection limit of 2.0×10−5 mol L−1 epinephrine. The sensors based on DB24C8 and DB18C6 (Types IV–IX) show poor responses in terms of calibration range and slope. The effect of the interferents on the response of the sensors reveals a high selectivity for the neurotransmitters over many inorganic cations, ascorbic and uric acids. The useful pH range for the three sensors is 3–7, the response time is fast (11 s), and the life span is long (2.5 months). Sensors (Types I and III) are successfully used for the quantification of dopamine and adrenaline in pharmaceutical preparations.
The effect of traditional flame retardants, nanoclays and carbon nanotubes in the fire performance of epoxy resin composites
Authors: Martins Marta S. S. , Schartel B. , Magalhães Fernão D. , Pereira C. M. C.
Published: May 2016

The effectiveness of distinct fillers, from micro to nano‐size scaled, on the fire behaviour of an epoxy resin and its carbon fibre reinforced composites was assessed by cone calorimetry. The performance was compared not only regarding the reaction to fire performance, but also in terms of thermal stability, glass transition temperature and microstructure. Regarding the fire reaction behaviour of nanofilled epoxy resin, anionic nanoclays and thermally oxidized carbon nanotubes showed the best results, in agreement with more compact chars formed on the surface of the burning polymer. For carbon fibre reinforced composite plates, the cone calorimeter results of modified resin samples did not show significant improvements on the heat release rate curves. Poorly dispersed fillers in the resin additionally caused reductions on the glass transition temperature of the composite materials. Copyright © 2016 John Wiley & Sons, Ltd.

Functional connectivity at rest is sensitive to individual differences in executive function: A network analysis
Authors: Reineberg Andrew E. , Banich Marie T.
Published: May 2016

Graph theory provides a means to understand the nature of network characteristics and connectivity between specific brain regions. Here it was used to investigate whether the network characteristics of the brain at rest are associated with three dimensions thought to underlie individual differences in executive function (EF)—common EF, shifting‐specific EF, and updating‐specific EF (Miyake and Friedman [2012]). To do so, both an a priori analysis focused mainly on select frontoparietal regions previously linked to individual differences in EF as well as a whole‐brain analysis were performed. The findings indicated that individual differences in each of the three dimensions of EF were associated with specific patterns of resting‐state connectivity both in a priori and other brain regions. More specifically, higher common EF was associated with greater integrative (i.e., more hublike) connectivity of cuneus and supplementary motor area but less integrative function of lateral frontal nodes and left temporal lobe nodes. Higher shifting‐specific EF was associated with more hublike motor‐related nodes and cingulo‐opercular nodes. Higher updating‐specific EF was associated with less hublike lateral and medial frontoparietal nodes. In general, these results suggested that higher ability in each of these three dimensions of EF was not solely characterized by the connectivity characteristics of frontoparietal regions. The pattern was complicated in that higher EF was associated with the connectivity profile of nodes outside of the traditional frontoparietal network, as well as with less hublike or centrality characteristics of some nodes within the frontoparietal network.

Spectral and spatial changes of brain rhythmic activity in response to the sustained thermal pain stimulation
Authors: Huishi Zhang Clara , Sohrabpour Abbas , Lu Yunfeng , He Bin
Published: May 2016

The aim of this study was to investigate the neurophysiological correlates of pain caused by sustained thermal stimulation. A group of 21 healthy volunteers was studied. Sixty‐four channel continuous electroencephalography (EEG) was recorded while the subject received tonic thermal stimulation. Spectral changes extracted from EEG were quantified and correlated with pain scales reported by subjects, the stimulation intensity, and the time course. Network connectivity was assessed to study the changes in connectivity patterns and strengths among brain regions that have been previously implicated in pain processing. Spectrally, a global reduction in power was observed in the lower spectral range, from delta to alpha, with the most marked changes in the alpha band. Spatially, the contralateral region of the somatosensory cortex, identified using source localization, was most responsive to stimulation status. Maximal desynchrony was observed when stimulation was present. The degree of alpha power reduction was linearly correlated to the pain rating reported by the subjects. Contralateral alpha power changes appeared to be a robust correlate of pain intensity experienced by the subjects. Granger causality analysis showed changes in network level connectivity among pain‐related brain regions due to high intensity of pain stimulation versus innocuous warm stimulation. These results imply the possibility of using noninvasive EEG to predict pain intensity and to study the underlying pain processing mechanism in coping with prolonged painful experiences. Once validated in a broader population, the present EEG‐based approach may provide an objective measure for better pain management in clinical applications.

Predictors of survival in parotid adenocarcinoma not otherwise specified: a National Cancer Database study of 3155 patients
Authors: Zhan Kevin Y. , Huang Andrew T. , Khaja Sobia F. , Bell Diana , Day Terry A.
Published: May 2016

Background

Parotid adenocarcinoma not otherwise specified (PANOS) is a common parotid cancer, but studies specifically on this subject are limited.

Methods

We conducted a retrospective review of the National Cancer Database.

Results

Ten percent of all parotid cancers were PANOS (n = 3155). Median age was 67 years. Most patients were men (62.8%) with high‐grade histology (67.2%). Regional metastasis was common (35.9%), whereas occult nodal metastasis (20.2% overall) was less frequent in non‐high‐grade lesions (8.5% vs 31.6%; p < .001). Distant metastasis was rare (7.9%). Five‐year overall survival (OS) was 47%. In multivariate analysis, age, regional metastasis, distant metastasis, high‐grade, and T classification were predictors of lower survival. Patients with stage III to IV disease receiving surgery and radiotherapy had a better OS than those receiving surgery alone (51% vs 41%; p < .001).

Conclusion

PANOS is an aggressive disease with frequent regional metastasis and low survival. Numerous variables are associated with worse survival. © 2016 Wiley Periodicals, Inc. Head Neck 38:1208–1212, 2016
The relation between remembered parental acceptance in childhood and self‐acceptance among young Turkish adults
Authors: Kuyumcu Behire , Rohner Ronald P.
Published: May 2016

This study examined the relation between young adults' age and remembrances of parental acceptance in childhood, and their current self‐acceptance. The study was based on a sample of 236 young adults in Turkey (139 women and 97 men). The adult version of the Parental Acceptance‐Rejection/Control Questionnaire for mothers and fathers along with the Self‐Acceptance subscale of the Psychological Well‐Being Scale, and the Personal Information Form were used as measures. Results showed that both men and women tended to remember having been accepted in childhood by both their mothers and fathers. Women, however, reported more maternal and paternal acceptance in childhood than did men. Similarly, the level of self‐acceptance was high among both men and women. However, women's self‐acceptance was higher than men's. Correlational analyses showed that self‐acceptance was positively related to remembrances of maternal and paternal acceptance among both women and men. Results indicated that age and remembered paternal acceptance significantly predicted women's self‐acceptance. Age and remembered maternal acceptance made significant and independent contributions to men's self‐acceptance. Men's remembrances of paternal acceptance in childhood did not make significant contribution to their self‐acceptance. Finally, the relation between women's age and self‐acceptance was significantly moderated by remembrances of paternal acceptance in childhood.
Relations between social comparison orientation and adjustment in Chinese adolescents: Moderating effects of initial adjustment status
Authors: Fu Rui , Chen Xinyin , Liu Junsheng , Li Dan
Published: May 2016

This 1‐year longitudinal study examined relations between social comparison orientation (SCO) and socioemotional adjustment and academic achievement. A sample of Grades 7 and 8 students (N = 336, initial M age = 14.08 years) in China participated in the study. Data were collected from self‐reports, peer assessments and school records. It was found that early SCO positively contributed to later academic achievement. Moreover, the relations between early SCO and later socioemotional adjustment were moderated by the initial status of adolescents. Specifically, SCO was positively associated with social competence and negatively associated with depression in initially competent and well‐adjusted adolescents, but the pattern of the associations was opposite in initially incompetent and poorly adjusted adolescents. The results indicate that whereas SCO may contribute directly to academic achievement, its contributions to socioemotional development might depend on adolescents' initial status in adjustment.
Perceived discrimination and antisocial behaviour among Chinese rural‐to‐urban migrant adolescents: Mediating effects of social support
Authors: Jia Xuji , Liu Xia
Published: May 2016

Using cross‐sectional data from rural‐to‐urban migrant adolescents in urban areas of Beijing, China, we examined the mediating effects of social support (i.e. teacher support and classmate support) in the relationship between perceived discrimination (PD) and antisocial behaviour (ASB) among Chinese migrant adolescents. Participants were 897 adolescents (459 boys and 438 girls, mean age = 13.34 years) from four migrant schools (68.8%) and four public schools (31.2%). Participants completed self‐report questionnaires concerning PD, ASB, teacher support and classmate support. Results indicated that Chinese migrant adolescents who perceived more discrimination were more likely to engage in ASB. Teacher support partially mediated the relationship between PD and ASB. Gender moderated this mediational relationship, such that teacher support exerted a mediating role among girls, but not boys. The findings suggest that reductions in teacher support may partially account for the effect of PD on ASB among Chinese migrant adolescents girls.
