Published: August 2017

AbstractBackground:Hyperparathyroidism (HPT) is a rare disease in the pediatric population, and optimal management may be unclear if it is due to an occult parathyroid adenoma. We present a case report of a pediatric patient with an occult, ectopic, supernumerary, parathyroid adenoma.Case presentation:A 13-year-old female who initially presented with anxiety was diagnosed with HPT. Preoperative imaging and bilateral neck exploration with four-gland biopsy were negative for any parathyroid adenoma. Postoperative MRI identified a thymic mass. She subsequently underwent video-assisted thoracoscopic thymectomy with resection of an intrathymic parathyroid adenoma.Conclusions:The diagnosis of pediatric HPT is increasing. Supernumerary or occult parathyroid adenomas are rare and add complexity to presurgical planning and management. Our case represents the rare occurrence of a pediatric ectopic supernumerary occult parathyroid adenoma treated with a two-stage approach utilizing multiple imaging studies. We provide a review of the pathology and propose an algorithmic approach to manage these complex patients.

Published: August 2017

AbstractThis paper quantitatively investigates the effect of transportation system on trade flows of four major port cities in China. Due to the significant country-pair heterogeneities in both intercept and slope terms, this paper introduced a random-coefficients model for parameters estimation. The empirical findings imply that the impact of the explanatory variables included in the gravity equation could be inaccurately estimated if the pair-wise heterogeneity biases in both intercept and slope terms are not accounted for during the econometric estimation of the model. In particular, in the presence of this heterogeneity, parameter estimates tend to be underestimated for country-pairs with higher trade volume and overestimated for those country-pairs with lower trade volume. In addition, the empirical results suggest that the improvement transportation system in port cities of China offers greater scope for its trade competitiveness.

Published: August 2017

AbstractThe real-time pricing plays an important role in demand-side management for smart grid. In this paper, we study real-time pricing strategy of electricity retailers by means of game theory in smart grid. The retailers are in the game situation where there is one leader with multi-followers. We propose a real-time electricity demand function and analyze the interactions between the retailers, then obtain its equilibrium solution. The analysis and simulation results of the equilibrium solution show the effectiveness of the proposed method.
5-Membered cyclic ethers via phenonium ion mediated cyclization through carbonate chemistry

Abstract
Cyclization of 2-(2-hydroxyethyl)phenol via DMC chemistry in acidic conditions is herein discussed for the first time. Reaction conditions have been investigated and optimized. This substrate is quite appealing as it incorporates a 2-hydroxyethyl moiety in ortho to the aromatic hydroxyl group capable of stabilizing the related phenonium ion. When the reaction mechanism was investigated via theoretical calculations, the results suggest that the most favorable pathway encompasses a DMC-mediated formation of the phenonium ion that is converted into the 2-(2-methoxyethyl)phenol. The related cyclic ether is then formed via intramolecular cyclization of this intermediate. This peculiar cyclization reaction is another example of the versatility of DMC herein used as solvent, methoxycarbonylation agent and leaving group in the intramolecular cyclization leading to the phenonium ion.
Evaluation of stearic acid modified industrial lime sludge waste as a filler in high density polyethylene composites
Authors: Kashyap Satadru , Datta Dilip 
Published: August 2017

Abstract
Industrial lime sludge (LS), an environmental hazard, is surface modified by stearic acid (SA) in order to reinforce high density polyethylene (HDPE) composites. Uncoated and SA-coated LS-reinforced HDPE composites are prepared and their mechanical, thermal, and morphological properties are studied and compared with each other. FTIR spectroscopy revealed successful grafting of SA onto LS particles while SEM morphology showed that SA coating hinders particle agglomeration in the HDPE matrix at higher filler loading. Mechanical properties such as tensile and flexural strength and modulus, elongation at break, and impact strength increased significantly for SA-coated LS composites due to uniform particle dispersion and effective filler-matrix interfacial interaction. The SA coating increased the entanglement at the filler-matrix interface thereby increasing the thermal decomposition of the coated composites from 500°C to 600°C. Additionally, it also reduced the water absorption rate of the coated composites in comparison with its uncoated counterpart. Thus, SA proves to be an efficient surface modifier for LS to produce HDPE composites with superior properties at a low cost. Needless to say, this study also suggests an alternative LS waste management route which offers benefits of reusing an industrial waste, decreasing the pollution, and developing fresh polymeric products.
Working Memory Replay Prioritizes Weakly Attended Events

Published: August 2017

AbstractOne view of working memory posits that maintaining a series of events requires their sequential and equal mnemonic replay. Another view is that the content of working memory maintenance is prioritized by attention. We decoded the dynamics for retaining a sequence of items using magnetoencephalography, wherein participants encoded sequences of three stimuli depicting a face, a manufactured object, or a natural item and maintained them in working memory for 5000 ms. Memory for sequence position and stimulus details were probed at the end of the maintenance period. Decoding of brain activity revealed that one of the three stimuli dominated maintenance independent of its sequence position or category; and memory was enhanced for the selectively replayed stimulus. Analysis of event-related responses during the encoding of the sequence showed that the selectively replayed stimuli were determined by the degree of attention at encoding. The selectively replayed stimuli had the weakest initial encoding indexed by weaker visual attention signals at encoding. These findings do not rule out sequential mnemonic replay but reveal that attention influences the content of working memory maintenance by prioritizing replay of weakly encoded events. We propose that the prioritization of weakly encoded stimuli protects them from interference during the maintenance period, whereas the more strongly encoded stimuli can be retrieved from long-term memory at the end of the delay period.

Vertebrate hearing organs manifest cellular asymmetries across the radial axis that underlie afferent versus efferent circuits between the inner ear and the brain. Therefore, understanding the molecular control of patterning across this axis has important functional implications. Radial axis patterning begins before the cells become postmitotic and is likely linked to the onset of asymmetric expression of secreted factors adjacent to the sensory primordium. This study explores one such asymmetrically expressed gene,Wnt9a, which becomes restricted to the neural edge of the avian auditory organ, the basilar papilla, by embryonic day 5 (E5). Radial patterning is disrupted whenWnt9ais overexpressed throughout the prosensory domain beginning on E3. Sexes were pooled for analysis and sex differences were not studied. Analysis of gene expression and afferent innervation on E6 suggests that ectopic Wnt9a expands the neural-side fate, possibly by re-specifying the abneural fate. RNA sequencing reveals quantitative changes, not only in Wnt-pathway genes, but also in genes involved in axon guidance and cytoskeletal remodeling. By E18, these early patterning effects are manifest as profound changes in cell fates [short hair cells (HCs) are missing], ribbon synapse numbers, outward ionic currents, and efferent innervation. These observations suggest that Wnt9a may be one of the molecules responsible for breaking symmetry across the radial axis of the avian auditory organ. Indirectly, Wnt9a can regulate the mature phenotype whereby afferent axons predominantly innervate neural-side tall HCs, resulting in more ribbon synapses per HC compared with abneural-side short HCs with few ribbons and large efferent synapses.SIGNIFICANCE STATEMENTWnts are a class of secreted factors that are best known for stimulating cell division in development and cancer. However, in certain contexts during development, Wnt-expressing cells can direct neighboring cells to take on specific fates. This study suggests that the Wnt9a ligand may play such a role in the developing hearing organ of the bird cochlea. This was shown through patterning defects that occur in response to the overexpression of Wnt9a. This manipulation increased one type of sensory hair cell (tall HCs) at the expense of another (short HCs) that is usually located furthest from the Wnt9a source. The extraneous tall HCs that replaced short HCs showed some physiological properties and neuronal connections consistent with a fate switch.
Human Occipital and Parietal GABA Selectively Influence Visual Perception of Orientation and Size

Published: August 2017

GABA is the primary inhibitory neurotransmitter in human brain. The level of GABA varies substantially across individuals, and this variability is associated with interindividual differences in visual perception. However, it remains unclear whether the association between GABA level and visual perception reflects a general influence of visual inhibition or whether the GABA levels of different cortical regions selectively influence perception of different visual features. To address this, we studied how the GABA levels of parietal and occipital cortices related to interindividual differences in size, orientation, and brightness perception. We used visual contextual illusion as a perceptual assay since the illusion dissociates perceptual content from stimulus content and the magnitude of the illusion reflects the effect of visual inhibition. Across individuals, we observed selective correlations between the level of GABA and the magnitude of contextual illusion. Specifically, parietal GABA level correlated with size illusion magnitude but not with orientation or brightness illusion magnitude; in contrast, occipital GABA level correlated with orientation illusion magnitude but not with size or brightness illusion magnitude. Our findings reveal a region- and feature-dependent influence of GABA level on human visual perception. Parietal and occipital cortices contain, respectively, topographic maps of size and orientation preference in which neural responses to stimulus sizes and stimulus orientations are modulated by intraregional lateral connections. We propose that these lateral connections may underlie the selective influence of GABA on visual perception.SIGNIFICANCE STATEMENTGABA, the primary inhibitory neurotransmitter in human visual system, varies substantially across individuals. This interindividual variability in GABA level is linked to interindividual differences in many aspects of visual perception. However, the widespread influence of GABA raises the question of whether interindividual variability in GABA reflects an overall variability in visual inhibition and has a general influence on visual perception or whether the GABA levels of different cortical regions have selective influence on perception of different visual features. Here we report a region- and feature-dependent influence of GABA level on human visual perception. Our findings suggest that GABA level of a cortical region selectively influences perception of visual features that are topographically mapped in this region through intraregional lateral connections.

Authors: Oliveira Guilherme Meyer 
Published: August 2017

Desde o momento em que as empresas disponibilizam uma vaga, os candidatos começam a trabalhar no gerenciamento de impressão, que nada mais é do que o candidato se transformar em um produto, em que ele aprende a mostrar para a empresa, o que a empresa quer ver, ou seja, vira um gestor da própria imagem. Deste modo, o estudo discutiu o seguinte problema de pesquisa: como o gerenciamento de impressão auxilia o comportamento dos candidatos a vagas em instituições financeiras, na percepção dos gerentes de agência. Tendo assim como objetivo analisar como o gerenciamento de impressão auxilia o comportamento de candidatos a vagas em instituições financeiras, na percepção dos gerentes de agências bancárias. Apoiou-se nos seguintes objetivos específicos: Identificar os traços de personalidade dos colaboradores escolhidos pelas empresas na percepção dos gerentes;verificar como funciona o processo de recrutamento e seleção em instituições financeiras e apontar as formas de gerenciamento de impressão utilizadas pelos candidatos a vagas em instituições financeiras na percepção dos gerentes. A justificativa da pesquisa baseou-se na concepção atual do mercado de trabalho, onde na visão dos candidatosé cada vez mais competitiva a busca pelo oficio perfeito, onde consiga segurança, estabilidade, motivação e qualidade de vida. Os principais autores utilizados para a discussão foram Chiavenato (2010), Marras (2009), Limongi-França (2011), Robbins (2005) e Bittencourt (2010). Ametodologia utilizada foi de natureza descritiva, com abordagem qualitativa. Foram sujeitos de pesquisa sete gerentes de agências bancárias de Porto Alegre - RS. A técnica de pesquisa e coleta de dados foi a entrevista com roteiro semiestruturado e um roteiro de observação nas agências visitadas, focando no próprio respondente e no ambiente aoseu redor. A técnica de análise de dados foi a análise interpretativa das respostas, com comparações dos dados pesquisados com o referencial teórico exposto no trabalho. A conclusão deste estudo foi de que todos os candidatos usam do gerenciamento de impressão, consciente ou inconscientemente, para se prepararem para as entrevistas. Cada candidato tentou mostrar suas melhores qualidades, de acordo com a sua percepção e suas experiências passadas, tanto pessoalmente, quanto culturais e sociais. A autopromoção foi a estratégia com maior representatividade; e a concordância e o comportamento não verbal como as táticas mais utilizadas, na visão dos entrevistados sobre os candidatos a vagas em agências bancárias.

Abstract

Background
As patients age, caregivers increasingly provide essential support and patient information. We sought to determine if patient-caregiver assessments of patient health differ and if differences contribute to burden in caregivers of older adults with cancer.

Materials and Methods
One hundred patients, aged ≥65, and their caregivers independently assessed patient function, comorbidity, nutrition, social activity, social support, and mental health. Caregivers completed the Caregiver Strain Index (CSI). Patient-caregiver assessments were compared using the Wilcoxon signed rank test and paired t test. Association between caregiver burden and differences between patient-caregiver assessments was examined using generalized linear regression.

Results
Median patient age was 70 (range 65–91) and 70% had advanced disease. Sixty percent of patients reported requiring help with instrumental activities of daily living (IADLs); most had good social support (median Medical Outcomes Study [MOS]-Social Support Survey score 92) and mental health (median Mental Health Inventory score 85).
Caregivers were a median age of 66 (range 28–85), 73% female, 68% spousal caregivers, and 79% lived with the patient. Caregivers rated patients as having poorer physical function (more IADLs dependency [p = .008], lower Karnofsky Performance Status [p = .02], lower MOS-Physical Function [p &lt; .0001]), poorer mental health (p = .0002), and having more social support (p = .03) than patients themselves. Three-quarters of caregivers experienced some caregiver burden (mean CSI score 3.1). Only differences in patient-caregiver assessment of the patient's need for help with IADLs were associated with increased caregiver burden (p = .03).

Conclusion
Patient-caregiver assessments of patient function, mental health, and social support differ. However, only differences in assessment of IADLs dependency were associated with increased caregiver burden.
