A representação do vestuário da elite feminina carioca (1854-1864) em Diva, de José de Alencar
Authors: Conceição Fernanda De Oliveira , Pinho Adeítalo Manoel 
Published: January 2020

O objetivo deste artigo foi entender como José de Alencar (1829-1877) representou o vestuário da elite feminina carioca (1854-1864) na diegese de seu romance urbano Diva (1959 [1864]). É de interesse não apenas à esfera acadêmica, cuja necessidade está em atualizar a obra alencariana, tendo aparo em aportes teóricos que possibilitem elucidar sua complexidade, provocando, com isso, outro olhar do século XIX, que se reflete na contemporaneidade; mas também aos estudos de gênero, permitindo entrever, por meio do vestuário, a atuação social da mulher de elite no período correspondente ao recorte temporal (1854-1864) e refletir sobre como o papel que lhe foi designado permanece hoje – desta vez, seu alcance não se limitando a apenas uma classe social. Como referencial teórico, há contribuições de Genette (2017 [1972]) e Sant’anna (1979 [1973]) à Narratologia e fizemos cotejo entre a pesquisa e outros trabalhos que mantêm relação com o tópico, como os de Hernandes (2015), Lajolo; Zilberman (1996), Souza (1993, 2005), dentre outros. Envolvido nos assuntos de seu tempo, Alencar acertou sobre os temas que escolheu escrever, garantindo às obras uma possível recepção por parte do público-alvo, seja através de leitoras fictícias que elaborou para garantir tal aceitação, seja na representação da vida privada do homem comum. Palavras-chave: Diva. José de Alencar. Diegese. Vestuário.

Authors: Fan Huibo , Chen Liang , Bao Xiaoyi 
Published: January 2020

An ultra-compact ultrasound sensor with a chalcogenide (ChG) microfiber and a silica microfiber is fabricated. It can detect the ultrasound wave generated by a piezoelectric transducer peaked at 3.7 MHz. The sensor shows the broadband ultrasound frequency response with a high signal-to-noise ratio (SNR), owing to the high refractive index and small Young’s modulus of ChG material. A ChG (

) microfiber of 2 µm diameter is adhered to the surface of a silica microfiber with a diameter of 5 µm via Van der Waals force; the transmission spectrum has high contrast due to multi-mode interference in this hybrid structure. The SNR response could be up to 70 dB, especially at low frequency due to the soft ChG microfiber as a sensing unit to magnify the ultrasound signal, along with an SNR over 12 dB at ultrasound of 31.2 MHz. As a comparison, a silica taper with the same size as the ChG microfiber is also placed on the silica microfiber with a diameter of 5 µm to detect an ultrasound signal from 18 kHz to 9.4 MHz with an SNR lower than that based on the ChG microfiber up to 38.8 dB, showing the high sensitivity of the ChG microfiber.

Abstract
The nutrients requirement for Cucurbita pepo L. (summer squash) for optimal yield and quality fruits production can be achieved through adequate nutrient supply. A field experiment was carried out during the cropping season of 2015 and 2016 at Landmark University Teaching and Research Farm, Omu-Aran, Nigeria to investigate the impact of Tithonia diversifolia, poultry manure and NPK fertilizer on the growth, yield, mineral and vitamin C content in the fruit of C. pepo. The experiment consisted of T. diversifolia at 30 tons ha−1, poultry manure at 10 tons ha−1, T. diversifolia at 30 tons ha−1 + Poultry manure 10 tons ha−1, T. diversifolia at 30 tons ha−1 + NPK (20:10:10), NPK (20:10:10) and control (no amendment of any kind) arranged in a randomized complete block design with four replications. The growth and fruit yield of C. pepo using the mean of the two years was increased by 68% and 2% respectively by T. diversifolia + poultry manure as compared to control due to an increase in nutrient availability in the soil with the amendment used. Also, Vitamin C content and Mg value of the fruit was increased by application of T. diversifolia as soil amendments as compared to the control. While the application of NPK fertilizer alone significantly increased the Ca, Mn and Fe contents of fruits. Fruit content of K was increased by 39 % by the application of T. diversifolia + NPK. Therefore, for the purpose of growing squash for the quality of fruits (vitamin C), the use of T. diversifolia at 30 tons ha−1 as organic fertilizer is sufficient for the cultivation, while for growing the crop with interest in quantity, application of T. diversifolia at 30 tons ha−1 + poultry manure at 10 tons ha−1 is recommended.
Recognizing Elder Abuse: An Interprofessional Simulation Experience With Prelicensure Health Care Students
Authors: Cunningham Shala , Cunningham Cynthia , Foote Lisa 
Published: January 2020

Background and Purpose:
A common role within all health care professions includes the ability to recognize and report elder abuse. However, teaching the characteristics and assessment of abuse can be difficult. To allow students to engage in a realistic case-based scenario within a health care team, an immersive simulation was developed involving the care of an elderly woman with signs of abuse. The purpose of this quasiexperimental study was to explore the influence of the experience on the participants' perceptions of interprofessional care and their understanding of the assessment of abuse.

Methods:
This study utilized a mixed-methods research design. A sample of convenience of nursing and physical therapy students (n = 143) from 3 institutions in southwest Virginia was utilized for this study. Participants' perceptions were assessed using the Interprofessional Socialization and Valuing Scale (ISVS) and through focus group interviews.

Results:
Students demonstrated a statistically significant improvement based on the Wilcoxon matched pairs test (P < .001) on all 21 questions of the ISVS. A phenomenological study design was employed for qualitative analysis of focus group interviews performed postsimulation to generate information about the students' perceptions of the experience. Two themes emerged from the interviews: (1) communication as a team to provide wholistic patient care and (2) recognition of abuse.

Discussion:
The students reported an improved understanding of collaboration on a health care team and how to investigate potential abuse occurring in the home. This further supports research suggesting the importance of interactive learning techniques in teaching health care students to recognize symptoms of elder abuse.
A New Method to Simultaneously Measure the Soil–Water Characteristic Curve and Hydraulic Conductivity Function Using Filter Paper

Published: January 2020

Abstract
The soil–water characteristic curve (SWCC) and hydraulic conductivity function (HCF) are widely used to study the hydraulic conductivity behavior of unsaturated soil. This article proposes a filter paper–based instantaneous profile method to simultaneously measure the SWCC and HCF of unsaturated soil. The method uses a small soil column that comprises several vertically stacked soil specimens sandwiched with filter papers. The water content and matric suction of the soil column are measured by weighing the soil specimens and filter papers, respectively, at regular time intervals. Therefore, the matric suction profiles and water content profiles can be obtained, and the SWCC and HCF can be calculated with the profile data. The method was applied to intact loess soil. The measured suction range is 0 to 2×105 kPa, and the measured hydraulic conductivity range is 10−5 to 10−13 m/s. Both SWCC and HCF curves display a bimodal characteristic and are consistent with previous mathematical models. This method is an inexpensive method to measure the SWCC and HCF in a large suction range.

Authors: Borges Caroline , Da Silva Lucas Antonio 
Published: January 2020

A reflexão que deu origem a este dossiê parte da constatação, fundada em nossa trajetória de pesquisa, da pouca visibilidade dada as comunidades pescadoras, suas práticas de pesca e seu mundo material nos estudos recentes da arqueologia brasileira. Para tentar promover um melhor contato e trocas entre diferentes pesquisadoras e pesquisadores, propusemos na reunião da SAB-Regional Sul de 2018, que ocorreu em Curitiba/PR entre 8 e 11 de outubro, um simpósio sobre a arqueologia da pesca chamado “Pesca e arqueologia: contextos, materiais, lugares, peixes e comunidades”. Durante este simpósio foram apresentados dezesseis trabalhos com os mais variados temas envolvendo a pesca. Em razão do interesse suscitado, decidimos ampliar a discussão em uma perspectiva nacional com a proposta deste dossiê chamado “Comunidades de pesca: pessoas, materiais, lugares e peixes”.
CREB Family Transcription Factors Are Major Mediators of BDNF Transcriptional Autoregulation in Cortical Neurons

Published: January 2020

BDNF signaling via its transmembrane receptor TrkB has an important role in neuronal survival, differentiation, and synaptic plasticity. Remarkably, BDNF is capable of modulating its own expression levels in neurons, forming a transcriptional positive feedback loop. In the current study, we have investigated this phenomenon in primary cultures of rat cortical neurons using overexpression of dominant-negative forms of several transcription factors, including CREB, ATF2, C/EBP, USF, and NFAT. We show that CREB family transcription factors, together with the coactivator CBP/p300, but not the CRTC family, are the main regulators of ratBDNFgene expression after TrkB signaling. CREB family transcription factors are required for the early induction of all the majorBDNFtranscripts, whereas CREB itself directly binds only toBDNFpromoter IV, is phosphorylated in response to BDNF-TrkB signaling, and activates transcription fromBDNFpromoter IV by recruiting CBP. Our complementary reporter assays withBDNFpromoter constructs indicate that the regulation ofBDNFby CREB family after BDNF-TrkB signaling is generally conserved between rat and human. However, we demonstrate that a nonconserved functional cAMP-responsive element inBDNFpromoter IXa in humans renders the human promoter responsive to BDNF-TrkB-CREB signaling, whereas the rat ortholog is unresponsive. Finally, we show that extensive BDNF transcriptional autoregulation, encompassing all majorBDNFtranscripts, occurs alsoin vivoin the adult rat hippocampus during BDNF-induced LTP. Collectively, these results improve the understanding of the intricate mechanism of BDNF transcriptional autoregulation.SIGNIFICANCE STATEMENTDeeper understanding of stimulus-specific regulation ofBDNFgene expression is essential to precisely adjust BDNF levels that are dysregulated in various neurological disorders. Here, we have elucidated the molecular mechanisms behind TrkB signaling-dependentBDNFmRNA induction and show that CREB family transcription factors are the main regulators ofBDNFgene expression after TrkB signaling. Our results suggest that BDNF-TrkB signaling may induceBDNFgene expression in a distinct manner compared with neuronal activity. Moreover, our data suggest the existence of a stimulus-specific distal enhancer modulatingBDNFgene expression.

Alzheimer's disease (AD) is the most common neurodegenerative disorder, resulting in the progressive decline of cognitive function in patients. Familial forms of AD are tied to mutations in the amyloid precursor protein, but the cellular mechanisms that cause AD remain unclear. Inflammation and amyloidosis from amyloid β (Aβ) aggregates are implicated in neuron loss and cognitive decline. Inflammation activates the protein-tyrosine phosphatase 1B (PTP1B), and this could suppress many signaling pathways that activate glycogen synthase kinase 3β (GSK3β) implicated in neurodegeneration. However, the significance of PTP1B in AD pathology remains unclear. Here, we show that pharmacological inhibition of PTP1B with trodusquemine or selective ablation of PTP1B in neurons prevents hippocampal neuron loss and spatial memory deficits in a transgenic AD mouse model with Aβ pathology (hAPP-J20 mice of both sexes). Intriguingly, while systemic inhibition of PTP1B reduced inflammation in the hippocampus, neuronal PTP1B ablation did not. These results dissociate inflammation from neuronal loss and cognitive decline and demonstrate that neuronal PTP1B hastens neurodegeneration and cognitive decline in this model of AD. The protective effect of PTP1B inhibition or ablation coincides with the restoration of GSK3β inhibition. Neuronal ablation of PTP1B did not affect cerebral amyloid levels or plaque numbers, but reduced Aβ plaque size in the hippocampus. In summary, our preclinical study suggests that targeting PTP1B may be a new strategy to intervene in the progression of AD.SIGNIFICANCE STATEMENTFamilial forms of Alzheimer's disease (AD) are tied to mutations in the amyloid precursor protein, but the cellular mechanisms that cause AD remain unclear. Here, we used a mouse model expressing human amyloid precursor protein bearing two familial mutations and asked whether activation of a phosphatase PTP1B participates in the disease process. Systemic inhibition of this phosphatase using a selective inhibitor prevented cognitive decline, neuron loss in the hippocampus, and attenuated inflammation. Importantly, neuron-targeted ablation of PTP1B also prevented cognitive decline and neuron loss but did not reduce inflammation. Therefore, neuronal loss rather than inflammation was critical for AD progression in this mouse model, and that disease progression could be ameliorated by inhibition of PTP1B.
Measuring Caenorhabditis elegans Spatial Foraging and Food Intake Using Bioluminescent Bacteria
Authors: Ding Siyu Serena , Romenskyy Maksym , Sarkisyan Karen S , Brown Andre E X 
Published: January 2020

Abstract
For most animals, feeding includes two behaviors: foraging to find a food patch and food intake once a patch is found. The nematode Caenorhabditis elegans is a useful model for studying the genetics of both behaviors. However, most methods of measuring feeding in worms quantify either foraging behavior or food intake, but not both. Imaging the depletion of fluorescently labeled bacteria provides information on both the distribution and amount of consumption, but even after patch exhaustion a prominent background signal remains, which complicates quantification. Here, we used a bioluminescent Escherichia coli strain to quantify C. elegans feeding. With light emission tightly coupled to active metabolism, only living bacteria are capable of bioluminescence, so the signal is lost upon ingestion. We quantified the loss of bioluminescence using N2 reference worms and eat-2 mutants, and found a nearly 100-fold increase in signal-to-background ratio and lower background compared to loss of fluorescence. We also quantified feeding using aggregating npr-1 mutant worms. We found that groups of npr-1 mutants first clear bacteria from within the cluster before foraging collectively for more food; similarly, during large population swarming, only worms at the migrating front are in contact with bacteria. These results demonstrate the usefulness of bioluminescent bacteria for quantifying feeding and generating insights into the spatial pattern of food consumption.
