La dramaturgie de la lumière strehlerienne
Authors: Palermo Antonio 
Published: April 2020

La lumière, Strehler a su en faire une composante fondamentale de ses spectacles jouant avec la transparence, la superposition de couches, l’ombre. Elle s’inscrit dans une époque théâtrale, comprise entre les années 1950 et 1990, et elle se développe d’une manière tout à fait personnelle, devenant une référence. Héritier d’une culture avant-gardiste et européenne, l’imaginaire strehlerien se forge dans un environnement milanais sillonné, à partir des années 1920, par des artistes - scénographes et plasticiens - très attentifs aux problématiques d’espace et de lumière. Chez Strehler, la pratique des éclairages s’articule non seulement à la scénographie, mais aussi au jeu, dont elle devient partenaire, ou au rythme musical. Elle peut être considérée comme un outil dramaturgique au service de la mise en scène.
Iluminação teatral em contextos escolares: uma proposta didática
Authors: Figueiredo Laura Maria de 
Published: April 2020

Este artigo aborda o potencial da iluminação artificial para práticas de ensino de teatro em contextos escolares, a partir dos conceitos relacionados às perspectivas da pedagogia do espectador de Flávio Desgranges e reflexões de Walter Benjamin sobre jogo infantil e brinquedo. Apresento um dispositivo didático para subsidiar o aprendizado inicial das relações entre luzes e cores por meio de uma maquete que simula o ilusionismo do palco de boca de cena, para propiciar leituras possíveis surgidas a partir da presença da luz como recurso cênico expressivo. Esse artefato foi desenvolvido para aulas de teatro para crianças e jovens em contextos escolares e inspirado nas ideias de Benjamin, reconhecido teórico do Teatro Épico de Brecht e pensador da educação infantil. A maquete propõe o espírito de brinquedo e brincar com luz, espaço e cor e possibilita a aproximação entre alguns tópicos básicos sobre iluminação teatral, corpos, objetos e espaço cênico que fazem parte dos conhecimentos que propiciam o desenvolvimento do espectador épico, seguindo as proposições de Desgranges.
Teatros do real e a abertura da representação
Authors: Ribeiro Martha de Mello 
Published: April 2020

Ao se colocar novamente em debate a milenar relação entre o teatro e o real, abre-se uma nova dimensão crítica sobre o lugar (ou o não lugar) do real na arte contemporânea. A pertinência e potência do debate se confirma pelas temáticas do irrepresentável, do inumano, do teatro confessional, do impossível, do biodrama, etc., que fundamentam o pensamento crítico contemporâneo sobre a representação. Poderíamos sugerir “teatros do real” enquanto construções de teatralidades, ou seja, modos de se encenar que produziriam efeitos de realidade. Porém, iremos entender “teatros do real” não como um efeito de realidade, mas como a possibilidade de abertura da representação.

Introduction: The introduction of biological medication in Juvenile Idiopathic Arthritis (JIA) proposes better therapeutic results with decreased pain and inflammation and consequent reduction in joint damage. The autonomic state can be a predictor for verifying the response to immunomodulation therapy. Thus, measuring heart rate variability can express autonomous behavior and possibly accompany the response to therapy through the expression of the inflammatory condition.
Objective: Analysis of heart rate variability in a child with Juvenile Idiopathic Arthritis using the anti-Tumor Necrosis Factor.
Methods: This is a clinical case report of an 8-year-old male with a diagnosis of JIA - oligoarticular form, using etanercept, admitted to Clínica Escola de Fisioterapia UNINORTE, Acre, Brazil in 2017. We analyzed laboratory and imaging tests, kinetic-functional evaluation, examination of cardiac autonomic modulation and physiotherapeutic treatment for analgesic, anti-inflammatory purposes, gaining flexibility, strength and postural re-education, according to CARE guidelines, case report guidelines.
Results: After medication administration, there was a decrease in pain and normalization of serum creatinine (0.50 mg / dL) and CRP (less than 6 mg / dL) and an increase in erythrocyte sedimentation rate (17 mm3). In the examination of heart rate variability, the linear indices in the time domain showed a predominance of parasympathetic activity (RMSSD: 35ms), with decreased sympathetic control measured through the frequency domain (LF: 27.1 un). However, non-linear methods showed low variability with little dispersion of RR intervals.
Conclusion: In the present report, the linear indices showed parasympathetic predominance and in the non-linear analysis a low heart rate variability with abnormal and insufficient adaptation of the autonomic nervous system in a child with juvenile idiopathic arthritis using biological medication.
Guidelines and practices on feeding children with cerebral palsy
Authors: Maggioni Luiza , Araújo Cláudia Marina Tavares de 
Published: April 2020

Introduction: Cerebral palsy refers to developmental disorders with direct repercussions on posture control and motricity. Its non-progressive and happens by damage of the brain still in development. Children with Cerebral Palsy (CP) present alterations in the oral functions, which makes feeding difficult and can bring serious health consequences, such as malnutrition and pneumonia. The caregiver plays an essential role of these children's diet, so they need to know the implementation of best practices to provide safe food. Guidelines for food practices and care are essential and need to be satisfactory and effective to avoid complications and reduce stress for the caregiver and child. The speech therapist is the skilled professional in assisting and intervening in children's eating difficulties and in guiding the caregiver. However, the guidance provided is not always incorporated into daily practice, and it is key to know and understand it appropriately.
Objective: To analyze the quality of the guidelines received and the feeding practices of caregivers of children with cerebral palsy.
Methods: This is an exploratory, cross-sectional study, involving 59 main caregivers of children with CP from 1 to 10 years of age, classified as level IV or V in the Gross Motor Function Classification System (GMFCS), with absent cervical control or compensation and fed orally. Data collection carried out through interviews with questions related to the characterization of the sample, quality of the guidelines received regarding feeding and care. The data were entered, pre-coded and processed by the Epi-info 3.5.4 program, using Fisher's exact test to compare categorical variables.
RESULTS: Of the total sample, 52 participants had already received speech-language guidance regarding feeding care. Of these, 76.9% were classified as satisfactory guidelines. The most emphasized aspect is related to posture, while signs of risk of bronchoaspiration were the least oriented.The quality of the guidelines was related to safe food consistency, inadequate utensils and facilitating maneuvers during children's feeding.
Conclusion: The findings reveal that most of the caregivers receive the feeding guidelines for children with CP , however, there is no periodic and systematic monitoring of what is actually incorporated into the feeding . This may indicate a potential gap between the guidelines received by the caregivers and the effectiveness of their daily practice, especially concerning protective measures of the lower respiratory tract.
Cannabis: from plant condemned by prejudice to one of the greatest therapeutic options of the century
Authors: Grosso Adriana Ferreira 
Published: April 2020

Cannabis sativa has a fascinating history and has been used by mankind for millennia. Many societies such as Greek, Roman, Chinese, African, Indian and Arabic take advantage of the plant's qualities, which are consumed as food, medicine, fuel, fibers or tobacco. The first reference found related to the therapeutic use of the plant data from 2700 B.C. and is present in the pharmacopoeia of the Chinese Emperor Shen-Nung, where this plant was recommended in the treatment of malaria, rheumatic pain, in irregular and painful menstrual cycles. The book “De Matéria Médica”, written by the doctor Pedânio Dioscórides considered thefounder of pharmacology, exposes Cannabis as one of the natural substances that can relieve inflammatory pain. In Brazil, African slaves brought a cannabis during the colonial period, around 1549. Then, its use spread quickly among black slaves and Indians, who started to cultivate it. Once the plant was popularized among French intellectuals and English doctors in the Indian imperial army, it started to be considered in our country as an excellent medicine for men, until it was suppressed by the police authorities in the 1930s. Only 60 years later important findings were highlighted around Cannabis with the System Endocannabinoid and its receptors, neurotransmitters such as anandamide and 2-AG, revolutionizing the understanding of molecular signaling that modulates pain and analgesia, inflammation, appetite, gastrointestinal motility and sleep cycles, immune cell activity and hormones among others.We are in front of a huge revolution in the therapeutic area, in which phytocabinoids represent one of the great therapeutic options of the century. We need a widespread disclosure that CBD is not marijuana and that its use for recreational purpose has nothing to do with the use of medical cannabis. Scientific research is seriously committed to the use of the substance in various pathologies. The role of information is absolute, being the main tool to clarify a society.

Aims: Cnidoscolus aconitifolius (CA) is a plant known to possess very high phenolic compound. The study evaluated hematological indices, anti-oxidative properties and gastroprotective potentials of CA leaf-supplemented diet.
Methodology: Male Wistar rats weighing between 80-100 g were divided into 5 groups of n=18. Group 1 animals were fed with normal diet and groups 2-5 were fed with diets supplemented with 1%, 2.5%, 5% and 10% of C. aconitifolius powdered leaves continuously for 4, 8 and 12 weeks. Hematological indices were examined in the whole blood plasma Malondialdehyde (MDA), Glutathione (GSH), Catalase (CAT) were investigated, and changes in stomach architecture were also examined via histology.
Results: There was a progressive increase in weight gain at different weeks of feeding with Cnidoscolus aconitifolius-supplemented diet (CAD). Malondialdehyde level decreased (p<0.05) significantly in 1% CAD at 8 weeks of feeding when compared to normal diet group. Glutathione at the 8th and 12th weeks of feeding with 1% CAD and 10% CAD significantly (p<0.05) decreased when compared to the group fed normal diet. Catalase activity increased (p<0.05) significantly in 1%, 2.5% and 5% CAD groups when compared to the group fed normal diet at 4 weeks of feeding. There was increase in haematological indices across all the groups during the weeks of feeding. The microscopic examination of the stomach epithelial layer reveals improvement with no serious damage across all the groups.
Conclusion: Cnidoscolus aconitifolius-supplemented diet moderately improves blood anti-oxidant against oxidative stress and the hematological indices with time. The diet also maintains the structural integrity of the stomach wall without causing any damage.

AbstractMesoporous silica nanoparticles (MSNs), one of the important porous materials, have garnered interest owing to their highly attractive physicochemical features and advantageous morphological attributes. They are of particular importance for use in diverse fields including, but not limited to, adsorption, catalysis, and medicine. Despite their intrinsic stable siliceous frameworks, excellent mechanical strength, and optimal morphological attributes, pristine MSNs suffer from poor drug loading efficiency, as well as compatibility and degradability issues for therapeutic, diagnostic, and tissue engineering purposes. Collectively, the desirable and beneficial properties of MSNs have been harnessed by modifying the surface of the siliceous frameworks through incorporating supramolecular assemblies and various metal species, and through incorporating supramolecular assemblies and various metal species and their conjugates. Substantial advancements of these innovative colloidal inorganic nanocontainers drive researchers in promoting them toward innovative applications like stimuli (light/ultrasound/magnetic)‐responsive delivery‐associated therapies with exceptional performance in vivo. Here, a brief overview of the fabrication of siliceous frameworks, along with discussions on the significant advances in engineering of MSNs, is provided. The scope of the advancement in terms of structural and physicochemical attributes and their effects on biomedical applications with a particular focus on recent studies is emphasized. Finally, interesting perspectives are recapitulated, along with the scope toward clinical translation.
Kirigami‐Design‐Enabled Hydrogel Multimorphs with Application as a Multistate Switch

Published: April 2020

AbstractMorphing materials have promising applications in soft robots, intelligent devices, and so forth. Among the various design strategies, kirigami structures are recognized as a powerful tool to obtain sophisticated 3D configurations and unprecedented properties from planar designs on common materials. Here, some kirigami designs are demonstrated for programmable, multistable 3D configurations from composite hydrogel sheets. Via photolithographic polymerization, perforated composite hydrogel sheets are fabricated, in which soft and active hydrogel strips are patterned in stiff and passive hydrogel frames. When immersed in water, the gel strips buckle out of plane due to swelling mismatch. In the kirigami structures, the geometric continuity is disrupted by the introduction of cutouts, and thus the degrees of deformation freedom increases remarkably. Multiple configurations are obtained in a single composite hydrogel by controlling the buckling direction of each strip. Multitier configurations are also obtained by using a hierarchically designed kirigami structure. A multicontact switch of an electric circuit is designed by harnessing the multitier gel configurations. Furthermore, a rotation mode is realized by introducing chirality in the kirigami design. The versatile design of the kirigami structure for programmable deformations should be applicable for other intelligent materials toward promising applications in biomedical devices and flexible electronics.

Published: April 2020

AbstractCollective excitation of periodic arrays of metallic nanoparticles by coupling localized surface plasmon resonances to grazing diffraction orders leads to surface lattice resonances with narrow line width. These resonances may find numerous applications in optical sensing and information processing. Here, a new degree of freedom of surface lattice resonances is experimentally investigated by demonstrating handedness‐dependent excitation of surface lattice resonances in arrays of chiral plasmonic crescents. The self‐assembly of particles used as mask and modified colloidal lithography is applied to produce arrays of planar and 3D gold crescents over large areas. The excitation of surface lattice resonances as a function of the interparticle distance and the degree of order within the arrays is investigated. The chirality of the individual 3D crescents leads to the formation of chiral lattice modes, that is, surface lattice resonances that exhibit optical activity.

Published: April 2020

AbstractOne of the major concerns in the application of nanocarriers in oncology is their scarce penetration capacity in tumoral tissues. Living organisms (cells and bacteria) present the capacity to navigate autonomously following chemical gradients being able to penetrate deeply into dense tissues. Currently, the possibility to employ these organisms for the transportation of therapeutic agents or nanocarriers has received huge attention. Herein, a new approach to deliver drug‐loaded nanoparticles achieving high penetration in tumoral matrices is presented. Escherichia coli bacteria wall is decorated with azide groups, whereas alkyne‐strained groups are incorporated on the surface of mesoporous silica nanoparticles loaded with a potent cytotoxic compound, doxorubicin. Both functional groups form stable triazole bonds by click‐type reaction allowing the covalent grafting of nanoparticles on living bacteria. Both motility and penetration capacity are evaluated in a 3D tumoral matrix model composed by a dense collagen extracellular matrix containing human fibrosarcome cells. The results confirm that bacteria are able to transport the nanoparticles crossing a thick collagen layer being able to destroy almost 80% of the tumoral cells located underneath. These findings envision a powerful strategy in cancer treatment by allowing a homogeneous distribution of therapeutic agents in the malignancy.
Biomimetic MXene‐Polyvinyl Alcohol Composite Hydrogel with Vertically Aligned Channels for Highly Efficient Solar Steam Generation
Authors: Yu Zhenchuan , Wu Peiyi 
Published: April 2020

AbstractSolar steam generation, which utilizes sustainable solar energy to produce fresh water, is regarded as a facile and effective way to solve water scarcity issues. However, challenges remain in terms of inefficient water transfer and vapor release, low solar absorption and conversion efficiency, and hydrophobic photothermal materials. Herein, enlightened by water transport through internal microchannels in trees, a tree‐inspired hydrogel (TIH) with vertically aligned channels incorporating MXene as the light absorber is fabricated. Due to the vertically aligned channels, the rapid transfer of water and unobstructed release of steam can be achieved. Furthermore, water state in molecular meshes can be changed by polymer−water interaction, and partial water can be activated to promote water evaporation. Excellent internal photothermal conversion efficiency and hydrophilicity of MXene are also conducive to evaporation. As a result, TIH has achieved an evaporation rate of 2.71 kg m−2 h−1 and energy efficiency of 90.7% under one sun irradiation, which is higher than membrane material and structure‐disordered hydrogel. This design principle, expandable manufacturing route, and excellent performance provide a potential way and design concept for water purification and desalination.

AbstractDespite their high theoretical energy density and low cost, lithium–sulfur batteries (LSBs) suffer from poor cycle life and low energy efficiency owing to the polysulfides shuttle and the electronic insulating nature of sulfur. Conductivity and polarity are two critical parameters for the search of optimal sulfur host materials. However, their role in immobilizing polysulfides and enhancing redox kinetics for long‐life LSBs are not fully understood. This work has conducted an evaluation on the role of polarity over conductivity by using a polar but nonconductive platelet ordered mesoporous silica (pOMS) and its replica platelet ordered mesoporous carbon (pOMC), which is conductive but nonpolar. It is found that the polar pOMS/S cathode with a sulfur mass fraction of 80 wt% demonstrates outstanding long‐term cycle stability for 2000 cycles even at a high current density of 2C. Furthermore, the pOMS/S cathode with a high sulfur loading of 6.5 mg cm−2 illustrates high areal and volumetric capacities with high capacity retention. Complementary physical and electrochemical probes clearly show that surface polarity and structure are more dominant factors for sulfur utilization efficiency and long‐life, while the conductivity can be compensated by the conductive agent involved as a required electrode material during electrode preparation. The present findings shed new light on the design principles of sulfur hosts towards long‐life and highly efficient LSBs.

Published: April 2020

AbstractThis review explores the current state of the art in spatially resolved characterization of mixed‐halide perovskite solar cells. As the size of perovskite cells and modules continues to grow, quantification of the spatial distribution of key cell parameters will become increasingly valuable in predicting ultimate cell‐level performance and tracking process homogeneity. Here, both high resolution microscopic approaches using scanning techniques and camera‐based methods for full‐area cell and/or module analysis are discussed. The value of this local data in predicting performance losses at the cell level is particularly emphasized. Measurable physical parameters sensitive to losses of voltage, current, fill factor, and efficiency are discussed together with selected experimental results. It is demonstrated that a combination of spatially resolved cell parameter mapping/imaging can be used to quantitatively discriminate various loss contributions at high resolution. The impact and control of inhomogeneities become particularly important when upscaling from small devices to large formats compatible with industrial mass production.
