Nanocellulose: Beyond the ordinary
Authors: Uetani Kojiro , Kitaoka Takuya
Published: June 2021

Nanocellulose is a collective term for nanoassemblies of macromolecular cellulose in fibrous and crystalline forms, mainly originating from woody bioresources. Fascinating physicochemical properties of nanocellulose, such as high strength, light weight, transparency, and low thermal expansion, have allowed development of nanocellulose-based functional materials, but most of these materials face serious competition from existing products. The inherent nanoarchitectures of nanocellulose cannot be reconstructed by artificial means, and they are expected to contain unknown functions that have not yet been achieved. Nanocellulose can “run its own show” in the forthcoming sustainable society through determining and highlighting its nanostructure-triggered novel material functions that are beyond the ordinary.
Influence of mechanical surface preparation methods on the bonding of southern pine and spotted gum: Tensile shear strength of lap joints
Authors: Leggate William , McGavin Robert L. , Outhwaite Andrew , Kumar Chandan , Faircloth Adam , Knackstedt Mark
Published: June 2021

Southern pine and spotted gum are two of Australia’s most important locally produced commercial timbers. However, internationally, they are amongst the most problematic species to glue cost-effectively, especially for sawn-laminate-based structural engineered wood products, such as glulam and cross-laminated timber. This study investigated the efficacy of different pre-gluing wood surface machining preparations on the tensile shear strength of lap shear samples prepared from both species. Surface machining methods tested included planing, face milling, and sanding post-planing with 40 and 80 grit sandpaper. Wood face milling is not currently used commercially in Australia and has not previously been adequately tested on Australian commercial timbers to improve wood adhesion. Planing is currently the most common method used internationally for preparing wood surfaces for gluing. For both species, face milling with fast feed speed (45 m/min), slow cutter speed (57 m/s), and sanding treatments post-planing resulted in significantly higher tensile shear strength compared to planing for lap shear samples that had been subjected to an accelerated weathering process. Performance differences in tensile shear strength between surface machining methods are likely to be related to the effects of these machining methods on surface roughness, fibrillation, and sub-surface cell damage.
Miscanthus: Beyond its use as an energy crop
Authors: Sa Mengyao , Zhang Bojin , Zhu Shengdong
Published: June 2021

Miscanthus is a tall perennial rhizomatous grass with C4 photosynthesis. Because of its high biomass yield, high carbohydrate and low ash content, high calorific value, remarkable environmental adaptability, high water and land use efficiency, and low fertilizer and pesticide requirements, it has become one of the most promising energy crops. Apart from energy uses, it can also be used as raw material for paper-making and for production of a variety of chemicals. Moreover, Miscanthus can also play an important role in environmental remediation and ecological improvement. It has been used to remedy polluted soil, improve the soil quality, and increase the biodiversity by providing habitat for animals and insects. However, its commercialization is still facing great challenge. More study is needed to further decrease its cultivation, harvesting, and processing costs. This editorial discusses opportunities and challenges of Miscanthus as an energy crop and in other applications.
Preparation of shape-stabilized phase change material by the valorization of oil palm waste: Reduced graphene oxide-activated carbon derived carbon matrix for thermal energy storage
Authors: Nasir Salisu , Hussein Mohd Zubir , Zainal Zulkarnain , Yusof Nor Azah
Published: June 2021

A shape-stabilized composite phase change material (SCPCM) made of n-nonadecane infused by capillary forces in a compressed reduced graphene oxide-activated carbon matrix (EFB(rGOAC)-M) was prepared from oil palm empty fruit bunch. The composite exhibited improved thermal properties and was used to fabricate an SCPCM by impregnation, in which the pores of the EFB(rGOAC)-M served as the support, while n-nonadecane was the central envelope. The EFB(rGOAC)-M exhibited a specific surface area of 680 m2 g-1 and an average pore size of 22 Å. The successful infiltration of n-nonadecane into the pores of EFB(rGOAC)-M was confirmed via nitrogen gas adsorption-desorption isotherms and scanning electron micrographs. According to the differential scanning calorimeter analysis, the composite SCPCM-5 exhibited melting and freezing temperatures of 37.25 °C and 25.58 °C, respectively, and an associated latent heat value of 82.72 J g-1 and -62.22 J g-1, respectively. There was no seepage during the phase change process (from solid to liquid, as the n-nonadecane was uniformly dispersed in the pores of the carbon matrix (EFB(rGOAC)-M) and held by the capillary and the surface tension forces of the carbon matrix. This innovative, inexpensive and environmentally friendly shape-stabilized phase change material could be applied for thermal energy storage applications.
A musicalidade como tema e como estrutura na lírica brasileira contemporânea
Authors: Lopez Cristian Javier
Published: June 2021

A lírica latino-americana em língua portuguesa oferece aos estudos literários do poema perspectivas frutíferas para sua análise. Essas vão desde as temáticas exploradas até as formas de composição poética. Buscamos, neste artigo, refletir sobre o fazer poético da escritora brasileira Helena Kolody (1912-2004) sob a perspectiva da musicalidade na sua obra lírica. Para isso, propomos a análise de dois poemas com o objetivo de demonstrar como essa característica, a musicalidade, pode ser entendida e apreciada nos seus poemas, seja como temática ou como elemento estruturador do discurso. Além disso, esperamos colaborar com o campo de estudos que busca resgatar as vozes femininas de poetas que ainda não pertencem ao cânone literário do continente e que deixaram uma importante contribuição para as Letras Latino-americanas.
Espaços urbanos em trânsito na poesia de Antonio Cicero
Authors: Sales Paulo Alberto da Silva
Published: June 2021

A poesia brasileira contemporânea, sobretudo aquela produzida desde a década de 1980, tem apresentado relações diretas entre as paisagens citadinas e a subjetividade. Em poéticas assumidamente espaciais, o sujeito lírico é confrontado com novas experiências urbanas que ampliaram sua percepção de mundo na observância dos gestos que marcam o cotidiano. Nessas revelações, a poesia passa a investir na primeira pessoa endereçada ao promover a expansão da noção de sujeito lírico que, por sua vez, passa a se identificar com espaços e imagens visuais. Essas associações criam um sujeito fora de si que, por meio de seu contato com diferentes lugares, cria uma nova experiência do olhar que rompe com as fronteiras dentro/fora. Partindo da expansividade e o endereçamento poético aos diversos espaços urbanos, apresentamos uma leitura de alguns poemas presentes nos livros A cidade e os livros (2002) e Porventura (2012), do poeta Antonio Cicero.  Nessas obras, as experiências do tema urbano aparecem em poemas que evidenciam a relação poesia e paisagem e como essa relação, no poeta em questão, marca a imprecisão tempo-espacial da cidade contemporânea ao mesclar as paisagens da urbe a espaços e a tempos míticos.
Sensory attributes of native stingless bee honey (Plebeia molesta): first approaches to the characterization and preference of local consumers.
Authors: Geisa Melisa Gabriela , Ciappini María Cristina , Hilgert Norma Inés
Published: June 2021

The sensory quality of a food is related to the consumer’s ethno-social and idiosyncratic conditions.  In this study, honeys from three different environments in the Chaco region of Córdoba (Argentina) were described qualitatively and quantitatively by specialized evaluators and rural peasant. Honeys with a wide diversity of sensory attributes were evidenced. The samples from Salinas Coast were characterized by high fluidity, those from Serrano Forest by quantity of crystals, and those from Plain Forest by the greatest persistence of taste. The rural population used some shared descriptors for honeys from similar geographical origin. Most rural consumers distinguished the honey from A. mellifera, Plebeia nov. sp. and P. molesta, which were also the preferred ones. We analyzed the results in relation to the Socio-ecological Theory of Maximization and concluded that the sensory components of P. molesta honeys allow their differentiation according to environment of origin and from honeys of other melliferous insects, which together with farmers´ idiosyncratic factors model the selection of the product.

Published: June 2021

At a commercial farrow-to-feeder pig system with 2,100 sows in Serbia, lesions resembling porcine ear necrosis syndrome were observed in 80% of the weaned pigs at 45–50 days of age. Pathomorphological examinations were carried out on 10 pigs that had been found dead. The gross lesions ranged from mild, superficial dermatitis to severe, deep inflammation with exudation, ulceration and necrosis. Histopathological examination revealed erosive and ulcerative dermatitis of the pinna with neutrophilic and lymphocytic infiltration and bacterial colonies in the crusts. Staphylococcus aureus (MRSA strain), Staphylococcus hyicus and Streptococcus group C were cultivated from eight, S. hyicus from two ear tissue scraping samples. All 10 samples were positive for treponemes and phylogenetic analysis of two polymerase chain reaction products confirmed the relationship to Treponema (T.) medium/vincentii and Treponema pedis. Treponemes were also detected in seven oral swabs that were analysed to obtain evidence of the transmission of this bacterium by ear biting. The contribution of non-infectious factors to this misbehaviour could not be ruled out as the crude protein concentration of the feed was inappropriate and the climate of the pig house was suboptimal. The concentrations of selected mycotoxins in the feed were not elevated. However, the contribution of both infectious and non-infectious factors to the onset of disease was most probable.
Microplastic contamination in commercial sea salt of Vietnam
Authors: Thi Ha Dang
Published: June 2021

This is the first study which assessed the microplastic pollution of sea salt products from Vietnam. The results obtained from 9 iodate fine table sea salt and 4 raw sea salt samples collected from different regions in Vietnam showed that microplastic were present in 100% of the salts samples. The mean concentration of microplastic was 787±101 items/kg and 340±26 items/kg for raw and fine sea salts, respectively.  For both raw and fine sea salt, fibers were the predominant type of microplastic, accounted more 60% of total microplastic particles. In added, three types of polymer were detected in 12 microplastic particles by FTIR, including polyethylene (PE), polypropylene (PP) and polystyrene, in which, the most common is PE (accounted 67%). With a mean daily salt consumption of 5-10g/day, the annual number of microplastic particles ingested per Vietnamese adult varies from 637 to 1241 particles from salt alone.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

ABSTRACT Objective: To analyze outcomes in fetuses and newborns exposed to infections during pregnancy. Methods: Cross-sectional, quantitative study, carried out in a public maternity hospital in Maceió, Alagoas, Brazil. The sample consisted of 145 medical records of pregnant women admitted between 2015 and 2018 with possible vertically transmitted infections. Incomplete medical records or those that did not make it possible to describe fetal/neonatal exposure were excluded. The chi-squared test was used to verify the association between variables. Results: A greater occurrence of congenital syphilis was observed (28.8%). There was more than one outcome in the same individual, such as low birth weight (39%), respiratory distress (20.5%), oligohydramnios (20%), congenital malformation and small size for gestational age (10.8%). Maternal infections and the number of prenatal visits revealed an association with fetal/neonatal outcome (p ≤ 0.05). Conclusion: The data obtained indicate the occurrence of unfavorable fetal/neonatal outcomes when related to neonatal infections and indicate the need for strategies that strengthen the coping with vertical transmissions.

Os resultados apontaram que o Parfor promoveu um pequeno aumento na quantidade de pedagogos nas unidades escolares, mas no que se refere ao Ideb os resultados não foram conclusivos.
Vulnerabilidade socioambiental e saúde em escolas no contexto do agronegócio
Authors: Beserra Lucimara , Pignati Wanderlei Antonio , Pignatti Marta Gislene , Oliveira Luã Kramer de
Published: June 2021

Resumo Neste estudo buscou-se compreender como estudantes de escolas rurais e urbanas identificam elementos da vulnerabilidade socioambiental no espaço escolar, no contexto do agronegócio, nos municípios de Campo Novo do Parecis, Sapezal e Campos de Júlio, localizados no estado do Mato Grosso, Brasil. Realizou-se um mapeamento participativo por meio do desenho dos processos e elementos destrutivos e protetores da vida no espaço escolar. Os processos e elementos protetores mais citados foram a escola, as árvores e as atividades agrícolas próximas às escolas, pela produção de cereais e algodão e a geração de empregos. Entretanto, a pulverização de agrotóxicos nas áreas de plantio próximas às escolas foi o processo destrutivo elencado de forma predominante nos mapas. Esses elementos compõem as relações e os processos de vulnerabilização socioambiental dos estudantes e das populações envolvidas nessas escolas. As facetas contraditórias (protetoras e destrutivas) evidenciadas sobre a produção agrícola demonstram uma dinâmica política de disputa da narrativa sobre o impacto sócio-sanitário-ambiental positivo e negativo do agronegócio e do uso de agrotóxicos. A construção dos mapas mostrou ser uma ferramenta que pode contribuir para o reconhecimento das vulnerabilidades socioambientais e potencializar a participação popular no processo de vigilância em saúde e ambiente.

HEALING INVISIBLE WOUNDS: DON DELILLO’S FALLING MAN AND THE RECOVERY OF TRAUMA
Authors: ÖZKAN Hediye
Published: June 2021

9/11 has not only caused dramatic, social, and political changes in the US history but also created a literature in which many authors seek to understand the aftermath of the attacks on the World Trade Center. Literature about 9/11 focuses particularly on how white or immigrant male masculinity is shaken due to trauma as it fails to present the intricate relationship between traumatized woman and recovery. Furthermore, literary criticism on 9/11 narratives centered on the analysis of the traumatic experiences of individuals does not take the discussion further by examining the recovery process of trauma. Therefore, the purpose of this study is to examine Don DeLillo’s Falling Man and the literary representation of the traumatized woman’s recovery, a topic mostly neglected within the scholarship of 9/11 novels. Confronting trauma creates a psychological and emotional catharsis which is a vital process leading to healing and rejuvenation as well as coming into terms with the self, memory, past, and society. Through the lenses of contemporary literary trauma theory and contemporary trauma stress studies, this paper examines traumatized woman’s recovery and healing to restructure, reorient, and rebuild self and life aftermath of 9/11 and its traumatic effects.

Published: June 2021

Cet article porte sur l’analyse des effets de la crise sanitaire auxquels les agents de collecte des déchets ont été confrontés entre mars et mai 2020. Les interactions sociales et les conditions de travail des agents ont été largement modifiées durant la période du confinement, nous proposons donc d’étudier la manière dont ils ont vécu cette crise sanitaire et la façon dont le métier s’est réinventé sur le plan identitaire. L’analyse, menée par le biais d’une enquête qualitative issue d’entretiens de groupe, a permis de faire apparaître six conditions de développement identitaire : le soutien matériel et les rapports sociaux avec la hiérarchie et la direction ; l’autonomie et les marges de manœuvre dans la gestion de la sécurité ; la définition de normes collectives et les rapports sociaux entre agents ; le partage d’expériences émotionnelles liées à l’apparition d’un risque inconnu ; les marques de gratitude et le rapport aux usagers ; et enfin, la mise en lumière des « invisibles » par les politiques et les médias. Cette recherche s’inscrit dans une perspective de prévention pour la santé et la sécurité au travail.
Facteurs de stress perçu par les élèves et les enseignants en éducation physique et sportive
Authors: NAKAS Raffi
Published: June 2021

Cette étude a pour but d’identifier les facteurs de stress, parmi six présentés, les plus ressentis par les élèves et les enseignants et d’observer d’éventuelles convergences et divergences. À l’aide d’un questionnaire (n = 466) de comparaison par paires (CPP) issu de la procédure de Condorcet, 242 élèves et 224 enseignants français ont répondu au sujet des modalités de pratique qu’ils ressentaient comme les plus stressantes. Les résultats révèlent que dans le cadre de l’enseignement de l’éducation physique et sportive (EPS) la cause « démonstration » entendue comme « se produire devant les autres » est unanimement ressentie comme stressante, mais qu’il existe des désaccords entre élèves et enseignants sur l’ordre des cinq autres causes, en particulier sur la place de la performance et de la constitution des équipes par les élèves eux-mêmes. Dans le même temps, les résultats soulignent peu de différences entre élèves : filles et garçons, 6e et 3e, ainsi qu’entre enseignants en fonction de leur sexe, leur ancienneté et leur niveau d’enseignement. Aussi, si les acteurs s’accordent sur les mêmes facteurs de stress, il parait légitime de s’interroger sur ce qui fondent leurs choix, notamment dans une école qui prône de plus en plus des pratiques bienveillantes tournées vers la confiance et le bien-être.
Learning Activities in Preschool Classrooms: Preferences of Preschool Teachers and Views of Parents
Authors: KONCA Ahmet Sami , DEMİRTAŞ İLHAN Seden
Published: June 2021

Early childhood teachers and their preferences are very important in order to apply a balanced curriculum in the early childhood education classroom. On the other hand, the views of parents play an important role in classroom implementations; although their views can sometimes create barriers for teachers, and sometimes teachers can be inspired by them. As a result, both teachers’ preferences and parents’ views need to be investigated in order to understand how they affect learning activities in early childhood education classrooms. With this purpose, this study aims to investigate preschool teachers’ preferences and parents’ views of learning activities applied in preschool classrooms through a case study. The study included 25 preschool teachers and 33 preschool children’s parents. Data collection took the form of semi-structured interviews held with the preschool teachers and the parents of preschool children. The results of the study revealed that the preschool teachers mostly preferred art, mathematics, and literacy activities, whilst science, drama, and body movement activities were the least implemented types of activities in the early childhood classroom. On the other hand, language, literacy and body movement activities were considered most important activities by parents. Moreover, the needs of the children, products, and processes were the first three reasons behind the teachers’ classroom activity preferences, whilst the teachers’ self-confidence in applying the activities was the least influential factor in their activity preferences.

La contabilidad como reloj socio-organizacional. Perspectiva analítica de la categoría tiempo en contabilidad
Authors: Arias Suárez Juan David , Cano Mejía Vanessa
Published: June 2021

El presente artículo analiza las concepciones de la categoría tiempo en la contabilidad financiera y de gestión, así como las implicaciones gerenciales para la toma de decisiones. El tiempo, como concepto o métrica, visto lineal o cíclicamente es clave para la determinación del actuar humano y social, y para la representación de la vida organizacional, la cual se analiza y proyecta con base en las segregaciones, fraccionamientos, asociaciones e interpretaciones de los hechos socioeconómicos incluidos en los diferentes periodos de construcción y presentación de la información contable. Mediante un método de revisión narrativa y analítica de la literatura, se establen relaciones y se contrastan argumentos asociados a categorías analíticas. Los hallazgos y resultados muestran tensiones conceptuales, normativas y métricas para las organizaciones y erigen a la contabilidad como una especie de reloj social y organizacional de la vida, representando diversos sentidos de los hechos cotidianos; de esa perspectiva se deriva que la relatividad de criterios, linealidad de los periodos y asimetría de la información abundan en la práctica contable, generan imprecisiones, impactan las decisiones y hacen hincapié en la necesidad de reinterpretar el relato socioeconómico, financiero y de gestión de la contabilidad para que alcance a captar y comprender las complejas dimensiones sociales y temporales.

Published: June 2021

La inversión extranjera directa es considerada como un factor principal en el crecimiento de la economía de los países como Colombia, ya que, permite incrementar la productividad, aumentar la innovación y fomentar el empleo; uno de los factores que determina la decisión final del inversionista es el componente fiscal, el cual se ve afectado por la doble imposición. Estudios previos afirman que los convenios de doble imposición vigentes en los países actúan como estrategia en el aumento de inversión extranjera directa, por lo tanto, a través de la metodología utilizada de mínimos cuadrados ordinarios este estudio tiene como objetivo evaluar la relación entre los convenios de doble imposición en materia del impuesto de Renta y la inversión extranjera directa en Colombia. Los resultados indican que dichos convenios no tienen ningún efecto sobre la misma.

Published: June 2021

El presente documento se aproxima y discute la literatura sobre contabilidad exterior: contabilidad sobre las entidades, producida por entidades externas. Se argumenta que dicha contabilidad es necesaria ante la necesidad de mejorar las formas de control social y la rendición de cuentas. La literatura es clasificada en cuatro categorías provenientes tanto de la misma revisión como de la discusión con ella: Sistemáticas, Militantes, Dialógicas y Emancipadoras. Se concluye que son diversos los mecanismos y los objetivos por los cuales se puede llevar a cabo una contabilidad exterior. Se plantea la necesidad de llevar a cabo más revisiones sistemáticas de contabilidad exterior en Colombia, así como mayor investigación en las formas de contabilidad exterior existentes en el país.
Knowledge, Fear, and Conscience: Reasons to Stop Flying Because of Climate Change
Authors: Wormbs Nina , Wolrath Söderberg Maria
Published: June 2021

Much research on the societal consequences of climate change has focused on inaction, seeking to explain why societies and individuals do not change according to experts’ recommendations. In this qualitative study, we instead consider people who have changed their behaviour for the sake of the climate: They have stopped travelling by air. We first asked them to elaborate their rationales for the behaviour change. Then, using topos theory to find thought structures, we analysed their 673 open-text answers. Several themes emerged, which together can be regarded as a process of change. Increased knowledge, primarily narrated as a process by which latent knowledge was transformed into insight, through experience or emotional distress, was important. Contrary to certain claims in the literature, fear stimulated change of behaviour for many in this group. Climate change was framed as a moral issue, requiring acts of conscience. Children were invoked as educators and moral guides. Role models and a supportive social context played an important part. Alternatives to flying were brought forward as a motive to refrain from flying. Only a few mentioned shame as momentous. Instead, stopping travelling by air invoked a feeling of agency and responsibility, and could also result in a positive sensation.
The Oldest Report of a 1537 Mexico Tsunami Based on Japanese Literature Is Erroneous
Authors: Hayashi Yutaka
Published: June 2021

According to the Global Historical Database by the National Centers for Environmental Information, the oldest historical tsunami record in Central America is the earthquake tsunami that occurred in Mexico in 1537; however, this record is doubtful because this tsunami is reported by no authority outside Japan. Here, I examined earthquake and tsunami catalogs and found the source of this suspicious data. Imamura (1925) compiled the first part of the chronological table of major earthquakes in the world from the earthquake catalog of the world by Milne (1912). During this compilation, information on the tsunami caused by the 1531 Spain–Portugal earthquake was not copied. The chronological table was published almost annually until 1962; during this time the table was revised in 1958 by Kawasumi, who was the author in charge at the time. The remarks for the 1531 Spain–Portugal earthquake tsunami should have been added during the revision, but the text “tsunami existence” was erroneously added to the next entry for the 1537 Mexico earthquake. The source of the 1537 tsunami report was this miscopy.

Lieux de mémoire et de pouvoir chez les Oman-Jagou en pays Idaatcha : Ègbakokou et Yaka, symboles de la dualité du pouvoir local.
Authors: Agbaka Opêoluwa Blandine
Published: June 2021

En plein cœur de Dassa-Zoumè, chef-lieu du département des Collines au centre nord du Bénin, deux lieux symbolisent la vitalité toujours renouvelée de la mémoire collective d’un royaume dont les origines remonteraient au XVIè siècle (Adjiba 2006). En effet, Les lieux de mémoire sont des creusets d’ancrage de la mémoire, mais d’une mémoire généralement collective. Leur vitalité est souvent l’objet d’un entretien périodique pour que la remémoration qui constitue leur essence vitale ne s’estompe pas. Au sein des communautés béninoises urbaines ou rurales, la célébration de la mémoire communautaire à travers des lieux dédiés à cet effet est un usage assez courant. Le présent article propose toutefois de présenter les cas particuliers d’Ègbakokou et Yaka, deux lieux représentant la dualité du pouvoir au sommet de la royauté en pays Idaatcha. Leur symbolique rime avec mémoire et pouvoir. Ancrés profondément dans l’organisation structurelle du royaume d’Igbo Idaatcha, ces deux lieux constituent chez les Oman-Jagou, deux altérités de la même réalité : l’expression et la manifestation du pouvoir. Si le Jagou (roi) règne sur Igbo Idaatcha et siège à Ègbakokou, l’Obaloké, le chef spirituel et la première autorité religieuse du royaume siège à Yaka.
Cultural Diplomacy and Brancusi’s Reception in the Digital Age in Romania
Authors: Stanciu Nicolae
Published: June 2021

The internet and media resources have opened new opportunities for digital cultural diplomacy and management of culture. Theoretically an ideal choice for cultural diplomacy, Constantin Brancusi’s reputation as a representative for government agency has suffered a crisis of reception. A Romanian-born and French-adopted sculptor, Brancusi has become a symbol of folklore and mythology but also a great, internationally recognized sculptor. This has been due to the existence of preferred or fixed models of desigining projects instead of involving teams of different backgrounds and incorporating cultural concepts in the political discourse. Approaching the topic with concepts of cultural diplomacy, media anthropology, heritage and online discourse, this case study deals with media events of cultural diplomacy broadcasted online in present day Romania. It emphasizes the potential that lies in cultural management and the important role of team spirit in designing public cultural policies and implementing projects.
Fetomaternal outcome in fibroid complicating pregnancy: a retrospective study

Published: June 2021

Background: Fibroids are the commonest benign tumour arising from the smooth muscle from uterus. Effects of fibroids on pregnancy and the effects of pregnancy on fibroids are a frequent clinical concern since these tumors are common in women of reproductive age. Most pregnant women with fibroids do not have any complications during pregnancy related to the fibroids. Pain is the most common problem and there may be a slightly increased risk of obstetrical complications like miscarriage, preterm labor and delivery, malpresentation and placental abruption.Methods: A retrospective study was carried out to study the fetomaternal complications in fibroid complicating pregnancies. Duration of study period was one year. Study was from 1 January 2019 to 31 December 2019 in government medical college, Kozhikode. Patients beyond 28 weeks of gestational age with fibroid complicating pregnancies were included. Case records were reviewed from medical records library government medical college, Kozhikode. Detailed review of patients including history, examination and ultrasound scan reports, mode of delivery, antepartum, intrapartum, postpartum complications and details of babies were also taken.Results: During the study period a total of 112 cases of fibroid complicating pregnancies were included in the study out of 15875 total number of deliveries. Majority of patients belonged to age group between 30 to 35 years (40.17%) and 28.1% belonged to between 35 and40 years. 63.39% of patients were multies. In most of the cases fibroid was diagnosed by the first trimester ultra sound itself. Size of uterus remained corresponding to gestational age in more than half of cases (56.25%). There was increased incidence of caesarean delivery (56.25%), preterm delivery (7.2%) and placenta praevia (2.8%) postpartum haemorrhage (10.71%) in the studied cases.Conclusions: Fibriod complicating pregnancies are associated with higher incidence of obstetric complications during all the phases of pregnancy. Proper antenatal care and assessment can reduce the adverse outcomes to a greater extent.
Identification and management of resistant hypertension
Authors: Ahmed Abass Mahamoud , Yuan Xiaochen
Published: June 2021

Resistant hypertension is defined as blood pressure being higher than the patient's target blood pressure despite the use of three or more different types of antihypertensive drugs at the optimal dose, and one of them should be a diuretic. The evaluation of patients with resistant hypertension should first confirm that they have true resistant hypertension. By eliminating or correcting false resistance factors, such as white coat hypertension, poor blood pressure measurement technique, poor drug compliance, improper dosage or combination of antihypertensive drugs, and white coat effects and clinical inertia. Resistant hypertension therapy includes improved compliance with the use of drugs, secondary hypertension detection and treatment, use of lifestyle measures and treatment of obesity, and other comorbidities. switching to a long-acting diuretic type of thiazide like chlorthalidone could improve the BP from the patients taking hydrochlorothiazide. This review paper illustrates briefly the identification of the underlying causes of resistant hypertension and therapeutic strategies, which may contribute to the proper diagnosis and an improvement of the long term management of resistant hypertension.

Socioeconomic Status and Mobility during the COVID-19 Pandemic: An Analysis of Eight Large Latin American Cities

Published: June 2021

This study analyzes mobility patterns during the COVID-19 pandemic for eight large Latin American cities. Indicators of mobility by socioeconomic status (SES) are generated by combining georeferenced mobile phone information with granular census data. Before the pandemic, a strong positive association between SES and mobility is documented. With the arrival of the pandemic, in most cases, a negative association between mobility and SES emerges. This new pattern is explained by a notably stronger reduction in mobility by high-SES individuals. A comparison of mobility for SES decile 1 vs decile 10 shows that, on average, the reduction is 75% larger in the case of decile 10. According to estimated lasso models, an indicator of government restrictions provides a parsimonious description of these heterogeneous responses. These estimations point to noticeable similarities in the patterns observed across cities. We also explore how the median distance traveled changed for individuals that travel at least 1 km (the intensive margin). We find that the reduction in mobility in this indicator was larger for high-SES individuals compared to low-SES individuals in six out of eight cities analyzed. The evidence is consistent with asymmetries in the feasibility of working from home and in the ability to smooth consumption under temporary income shocks.
USP28 promotes aerobic glycolysis of colorectal cancer by increasing stability of FOXC1

Published: June 2021

Aerobic glycolysis is essential for cancer cell metabolism and growth. Deubiquitinase, USP28 (ubiquitin specific peptidase 28), could maintain stability of proteins involved in tumor progression. This study was performed to investigate the role of USP28 in aerobic glycolysis of colorectal cancer. Our data showed that USP28 mRNA and protein expressions were enhanced in colorectal cancer tissues and cells. Functional assays demonstrated that overexpression of USP28 promoted cell proliferation and aerobic glycolysis of colorectal cancer, while USP28 inhibition could reverse these effects. Protein expression of Forkhead Box C1 (FOXC1) was increased by USP28 over-expression, whereas knockdown of USP28 aggravated cycloheximide (CHX; protein synthesis inhibitor) stimulated decrease of FOXC1. Moreover, proteasome inhibitor, MG132, could rescue USP28 silence-induced degradation of FOXC1. Overexpression of FOXC1 counteracted the suppressive effects of USP28 interference on colorectal cancer cell viability and aerobic glycolysis. In conclusion, USP28 enhanced cell viability and aerobic glycolysis of colorectal cancer by stabilizing FOXC1, suggesting that USP28-FOXC1 might be a novel therapeutic avenue for colorectal cancer.
