Purpose Intravoxel incoherent motion is a diffusion-weighted imaging magnetic resonance imaging technique that measures microvascular perfusion from a multi-b value sequence. Intravoxel incoherent motion microvascular perfusion has not been directly compared to conventional dynamic susceptibility contrast perfusion-weighted imaging in the context of acute ischemic stroke. We determined the degree of correlation between perfusion-weighted imaging and intravoxel incoherent motion parameter maps in patients with acute ischemic stroke. Methods We performed a retrospective cohort study of acute ischemic stroke patients undergoing thrombectomy treatment triage by magnetic resonance imaging. Intravoxel incoherent motion perfusion fraction maps were derived using two-step voxel-by-voxel post-processing. Ischemic core, penumbra, non-ischemia, and contralateral hemisphere were delineated based upon diffusion-weighted imaging and perfusion-weighted imaging using a Tmax >6 s threshold. Signal intensity within different brain compartments were measured on intravoxel incoherent motion (IVIM f, IVIM D*, IVIM fD*) parametric maps and compared the differences using one-way ANOVA. Ischemic volumes were measured on perfusion-weighted imaging and intravoxel incoherent motion parametric maps. Bland–Altman analysis and voxel-based volumetric comparison were used to determine the agreements among ischemic volumes of perfusion-weighted imaging and intravoxel incoherent motion perfusion parameters. Inter-rater reliability on intravoxel incoherent motion maps was also assessed. Significance level was set at α < 0.05. Results Twenty patients (11 males, 55%; mean age 67.1 ± 13.8 years) were included. Vessel occlusions involved the internal carotid artery (6 patients, 30%) and M1 segment of the middle cerebral artery (14, 70%). Mean pre-treatment core infarct volume was 19.07 ± 23.56 ml. Mean pre-treatment ischemic volumes on perfusion-weighted imaging were 10.90 ± 13.33 ml (CBV), 24.83 ± 23.08 ml (CBF), 58.87 ± 37.85 ml (MTT), and 47.53 ± 26.78 ml (Tmax). Mean pre-treatment ischemic volumes on corresponding IVIM parameters were 23.20 ± 25.63 ml (IVIM f), 14.01 ± 16.81 ml (IVIM D*), and 27.41 ± 40.01 ml (IVIM fD*). IVIM f, D, and fD* demonstrated significant differences ( P < 0.001). The best agreement in term of ischemic volumes and voxel-based overlap was between IVIM fD* and CBF with mean volume difference of 0.5 ml and mean dice similarity coefficient (DSC) of 0.630 ± 0.136. Conclusion There are moderate differences in brain perfusion assessment between intravoxel incoherent motion and perfusion-weighted imaging parametric maps, and IVIM fD* and perfusion-weighted imaging CBF show excellent agreement. Intravoxel incoherent motion is promising for cerebral perfusion assessment in acute ischemic stroke patients.

Objetivo: mostrar cómo pacientes de pueblos originarios (Mayas) que padecen diabetes tipo 2 manejan recursos de los diferentes modelos de atención para atender su enfermedad. Material y métodos: el diseño del estudio fue de métodos mixtos de tipo secuencial; incluyó un cuestionario ( n=195), entrevistas cualitativas cortas ( n=103) y 20 entrevistas a profundidad entre población originaria Maya diagnosticada con diabetes tipo 2, usuarios de servicios de atención pública para la salud en tres estados de México: Chiapas, Yucatán y Quintana Roo. Resultados: las trayectorias de atención se orientaron de acuerdo con las creencias sobre el origen de la enfermedad. La ruta seguida puede iniciar en los servicios públicos de salud, la medicina privada, tradicional o alternativa, o en el ámbito de las creencias religiosas; pero en algún punto se transita por todos estos recursos. La utilización de los recursos institucionales de la atención pública en salud depende de la apreciación de los pacientes sobre la eficacia del sistema de salud y las causas de la enfermedad, frecuentemente emocionales: sustos, enojos y/o preocupaciones. Conclusiones: las y los participantes buscaron activamente atender su salud por varios medios; esto implica que en la trayectoria de atención se mezclan modelos, recursos y medicamentos, en parte debido a las condiciones de pobreza. La evidencia puede ser usada para ajustar los programas de educación para la salud, siguiendo la propuesta de la promoción de la salud sobre impulsar que las personas tengan mayor control de su propia salud.
Nitric oxide loading reduces sickle red cell adhesion and vaso-occlusion in vivo

Published: September 2019

Abstract
Sickle red blood cells (SSRBCs) are adherent to the endothelium, activate leukocyte adhesion, and are deficient in bioactive nitric oxide (NO) adducts such as S-nitrosothiols (SNOs), with reduced ability to induce vasodilation in response to hypoxia. All these pathophysiologic characteristics promote vascular occlusion, the hallmark of sickle cell disease (SCD). Loading hypoxic SSRBCs in vitro with NO followed by reoxygenation significantly decreased epinephrine-activated SSRBC adhesion to the endothelium, the ability of activated SSRBCs to mediate leukocyte adhesion in vitro, and vessel obstruction in vivo. Because transfusion is frequently used in SCD, we also determined the effects of banked (SNO-depleted) red blood cells (RBCs) on vaso-occlusion in vivo. Fresh or 14-day-old normal RBCs (AARBCs) reduced epinephrine-activated SSRBC adhesion to the vascular endothelium and prevented vaso-occlusion. In contrast, AARBCs stored for 30 days failed to decrease activated SSRBC adhesivity or vaso-occlusion, unless these RBCs were loaded with NO. Furthermore, NO loading of SSRBCs increased S-nitrosohemoglobin and modulated epinephrine’s effect by upregulating phosphorylation of membrane proteins, including pyruvate kinase, E3 ubiquitin ligase, and the cytoskeletal protein 4.1. Thus, abnormal SSRBC NO/SNO content both contributes to the vaso-occlusive pathophysiology of SCD, potentially by affecting at least protein phosphorylation, and is potentially amenable to correction by (S)NO repletion or by RBC transfusion.

Abstract
Objective
The Clinical Practice Guidelines for Dementia in Australia provide evidence-based recommendations for the assessment, diagnosis, and care of people with dementia and their informal carers. The extent to which current Australian post-diagnosis care reflects these recommendations is not well understood. This brief report provides a snapshot of current practice related to three key recommendations from the Guidelines: occupational therapy, exercise, and informal carer support.

Results
Nursing (n = 3) and allied health clinicians (n = 29) provided data about 1114 consultations with people with dementia and/or informal carers over a 9-month study period. Results showed that delivery of evidence-based dementia care remains a significant challenge in Australia. Clinicians found it difficult to tailor exercise interventions to overcome cognitive and organisational barriers to adherence during and between consultations. Occupational therapists primarily focussed on functional assessment rather than on delivering evidence-based interventions. Clinicians also found it difficult to identify and address the array of needs reported by informal carers, especially when the person with dementia is present during the consultation. Though these results are reported by a selected sample, they emphasise the need for innovative knowledge translation strategies to facilitate widespread quality improvement in post-diagnosis dementia care.

Convert one outfit to more looks: factors influencing young female college consumers’ intention to purchase transformable apparel
Authors: Lang Chunmin , Wei Bingyue 
Published: September 2019

AbstractTransformable apparel offers two or more functional and/or alternative aesthetic styles through various manipulative methods, which is considered a sustainable alternative in the fashion industry to reduce excess clothing consumption. The study intends to identify the influences of environmental apparel knowledge, environmental beliefs, and personal values on consumers’ intention to purchase transformable apparel products. The theory of reasoned action (TRA) was applied as the foundation for the conceptual framework, which considered attitude and social factors to be crucial factors influencing the intention. Data were collected from 306 female college students in the United States through an online survey. Proposed hypotheses were tested by structural equation modeling (SEM). The results confirmed the positive influences of the tendency for creative choice, environmental beliefs, environmental apparel knowledge, and attitude on female college students’ intention to purchase transformable apparel products. Furthermore, practical and theoretical implications based on the results were discussed as well.
Strategies to Counter Weight Loss-Induced Reductions in Metabolic Rate
Authors: Palmer Biff F. , Clegg Deborah J. 
Published: September 2019

Abstract
A significant percentage of the population is classified as obese, and there is a growing need to develop novel therapy to reduce body weight. It has long been appreciated that caloric restriction and exercise are the cornerstones of any weight loss method. This review outlines the challenges faced when attempting to achieve weight loss and the metabolic adaptations that ensue upon reductions in body weight which make sustaining weight loss extremely difficult. We discuss the need for novel approaches to weight loss that would increase basal metabolic rate and counter the biological adaptations that provide barriers for maintaining weight reduction. We introduce two metabolic processes, hypobaric hypoxia and cold exposure, which, when activated, cause increased metabolic rate even in the presence of reduced caloric intake. While we do not suggest that these are long-term viable options for methods to achieve weight loss, we are introducing these as pathways that may be targeted to eventually develop novel therapies to achieve sustainable weight loss.

Os custos da corrupção para o mundo superam 3,6 trilhões de dólares por ano, perto de 5% do produto interno bruto (PIB) global, segundo a Organização das Nações Unidas (ONU), a qual destaca que essas perdas em fraudes, subornos, evasão fiscal e lavagem de dinheiro estão entre os principais bstáculos para o cumprimento dos Objetivos do Desenvolvimento Sustentável (ODS).A corrupção desvia recursos fundamentais para o desenvolvimento das nações e afeta a competitividade dos países. Traz prejuízos às finanças, à reputação e à cultura das organizações, o que em última instância ameaça sua sobrevivência. Uma economia alicerçada por esquemas de desvios ilegais de ecursos não se sustenta.
ENSINO DE LITERATURAS EM PRÉ-VESTIBULARES SOCIAIS: IDENTIDADES EM TRÂNSITO / Teaching literatures in social pre-college preparatory courses: identities in transit
Authors: Pereira Maria Betânia Almeida 
Published: September 2019

O artigo discorre acerca das ações desenvolvidas no projeto de iniciação à docência, “O ensino do texto literário e suas inter-relações com outras linguagens”, iniciado em 2016 na Faculdade de Formação de Professores, da Universidade do Estado do Rio de Janeiro (FFP-UERJ). Tendo em vista o recorte do corpus para análise, nos detivemos em uma das experiências cujo enfoque volta-se ao ensino do texto literário em pré-vestibulares sociais. Desta forma, a pesquisa objetiva: contextualizar o projeto e seus desdobramentos; refletir sobre o ensino de literatura em pré-vestibulares sociais, considerando algumas abordagens teórico-metodológicas; trazer à baila depoimentos de professores voluntários - licenciandos em Letras da FFP-UERJ - de forma a repensar o ethos de professor e sua construção identitária nesse processo de ensino-aprendizagem. A fundamentação teórica apoiou-se em: Antonio Candido (2004), quando defende a literatura enquanto direito de todos; Todorov (2009) ao pontuar uma visão reducionista no ensino de literatura e ao analisar a formação universitária; Brian Street (2014), ao considerar as práticas sociais de leitura e de escrita, pondo em relevância o método etnográfico; Stuart Hall (2014) em sua conceituação das identidades enquanto representações sociais; Paulo Freire (1996) ao situar o processo de ensino-aprendizagem como via de mão dupla em que professores e alunos se constroem e se reconstroem; dentre outros. Esperamos que o trabalho possa motivar debates em torno do ensino de literatura, em diversificados espaços de aprendizagens.

A primeira vez que entrei em um museu ainda estava no sexto ano. Era o Museu Imperial de Petrópolis, o mais próximo à minha cidade - Nova Friburgo. Nas férias que passávamos meu irmão e eu no Rio de Janeiro, frequentávamos o Palácio do Catete. Sua gruta foi palco de inúmeras brincadeiras nossas. Comecei a descobrir os espaços culturais do Rio somente quando comecei minha primeira graduação. O Parque das ruínas foi o primeiro. O Museu do Índio e o Villa Lobos descobri por acaso por acas. A Casa Rui Barbosa, no mesmo bairro, foi palco de longas conversas sobre Eisenstein. O Real Gabinete e seu acervo mexe com meu imaginário tanto quanto os astros que observo no Planetário de Nova Friburgo, paixão que herdei de meu irmão. Há diversos espaços que não estão presentes por falta de permissão para fotografá-los. Ainda que seja um equipamento portátil o que tenho levado ele ainda causa estranheza e fui impedida de fotografar principalmente os interiores. No final da exposição há um link no qual é possível visitar os locais de onde tirei as fotos em 360 graus. Experimente fazê-lo em um óculos de realidade virtual se você tiver a oportunidade. https://photos.app.goo.gl/tCbfa1ttJmhYErr96

Enhancing Groundwater Recharge with Sand Ditches
Authors: Abu-Zreig Majed M , Fujimaki Haruyuki , Abdel Baset Mohamed 
Published: September 2019

Abstract. Localized and artificial groundwater recharge is an important water management strategy in arid regions. However, artificial recharge is limited by the hydraulic characteristics of surface soil which control downward water percolation to the aquifers. In heavy soils with low infiltration and hydraulic conductivity rate, water percolation can be enhanced by constructing deep ditches filled with highly permeable materials, such as sand. Laboratory experiments were conducted to examine the effect of constructing a deep sand ditch across the slope of a soil box (50 × 20 × 25 cm3) on runoff and deep percolation to the drainage outlet of the soil box. A sandy loam soil packed in two bulk densities (1200 and 1500 kg/m3) was used for the experiments. The experiments were carried out using simulated steady runoff of about 300 mL/min for a duration of 60 min. Experimental results showed that sand ditches greatly enhanced water deep percolation in soils but their relative effect was more profound in compacted high-density soil compared to soil having low-density. The drainage water collected from compacted soil boxes in the presence of sand ditches increased by 10 times compared to control soil without sand ditches. In the case of low-density soil, the presence of sand ditches eliminated the runoff but the increase in drainage water was about 18% compared to control. The experimental results clearly revealed that creating high infiltration zones within the soil matrix, such as sand ditches, significantly increased water deep percolation and herewith groundwater recharge in drylands, especially in heavy soils.

Abstract.The published data on equilibrium moisture content vs. equilibrium relative humidity (EMC-ERH) for wood pellet do not cover the range of temperature and relative humidity to which a pellet is exposed to during its storage and handling. A few published EMC-ERH relations covering a wider range of temperatures and relative humidity are available for solid wood (lumber) and wood chips. The question is whether the data for solid wood is applicable to wood pellets. For this research, we examined the sorption isotherms of wood pellets and solid wood. The analysis shows that EMC for solid wood is higher than the EMC for wood pellet for a relative humidity larger than 30%. The slope of EMC-ERH isotherm for solid wood in the range of 30%-70% is slightly steeper than the slope of isotherm for wood pellet, indicating the pellet’s EMC is less sensitive to ERH when compared to EMC-ERH for solid wood. Keywords: EMC, ERH, Densified biomass, Equilibrium moisture content, Equilibrium relative humidity, Solid wood, Wood pellets.
