Authors: Kakepoto Ghulam Fatima , Xiao Shaoqiu , Mangi Farman Ali
Published: April 2021

A wideband circularly polarized (CP) array antenna has significant importance in modern communication system. In this paper, we proposed a wide band CP array by combing dual split ring resonators (DSRRs) to dual layer microstrip antenna. A 2 × 2 dual-layer microstrip antenna array is used to radiate wide band linearly polarized wave, and the 3 × 3 four-layer DSRRs is used as an external polarizer which converts linearly polarized wave to circularly polarized wave at distinct frequencies. The proposed array achieves an impedance bandwidth of 20% ranging from 4.57–5.57 GHz and AR bandwidth of 16.83% ranging from 4.57–5.41 GHz. The prominent futures of the proposed array are wide impedance bandwidth on desired frequencies. This new concept is theoretically and experimentally investigated to evaluate the performance of the proposed array, which allows a better prospect for the application of radar and satellite communication systems.
Monitoring and simulating the distribution of phytoplankton in constructed wetlands based on SPOT 6 images
Authors: Song Yumeng , Zhang Jing
Published: April 2021

We integrated hyperspectral and field-measured chlorophyll-a (Chl-a) data from the Kristalbad constructed wetland in the Netherlands. We developed a best-fit band ratio empirical algorithm to generate a distribution map of Chl-a concentration (C
chla) from SPOT 6 imagery. The C
chla retrieved from remote sensing was compared with a water quality model established for a wetland pond system. The retrieved satellite results were combined with a water quality model to simulate and predict the changes in phytoplankton levels. The regression model provides good retrievals for Chl-a. The imagery-derived C
chla performed well in calibrating the simulation results. For each pond, the modeled C
chla showed a range of values similar to the Chl-a data derived from SPOT 6 imagery (10–25 mg m−3). The imagery-derived and prediction model results could be used as the guiding analytical tools to provide information covering an entire study area and to inform policies.

Published: April 2021

Although phosphate rock has been considered as a potential new rare earth elements (REEs) resource, the recovery of REEs from phosphate rock is impeded by technical challenges and cost issues. This study investigated the effects of operation conditions on the leaching efficiencies of REEs and phosphorus from Zhijin phosphate ore, a large phosphate deposit in China. The leaching process overtime was also studied by chemical analysis, scanning electron microscope with energy dispersive spectroscopy (SEM-EDS), and X-ray diffraction (XRD). The results indicated that the REEs from Zhijin phosphate ore were mainly present in fluorapatite and dolomite, and REEs had similar trends of leaching efficiency to those of phosphorus and magnesium. Under the conditions of 25 wt% phosphoric acid concentration in the initial pulp, a weight ratio of liquid to solid of 12 mL/g, a temperature of 60°C, an agitation speed of 220 rpm, and leaching time of 120 min, REEs and phosphorus leaching efficiencies of 97.8% and 99.7% were obtained. Most parts of dissoluble substances were decomposed within 30 min. Chemical analysis, SEM-EDS, and XRD results indicated that leaching efficiencies of minerals in Zhijin phosphate ore increased following the order: quartz, aluminosilicate, pyrite, fluorapatite, dolomite, and calcite.

Authors: Plotzky Christian , Lindwedel Ulrike , Bejan Alexander , König Peter , Kunze Christophe
Published: April 2021

With an ever-increasing need of skilled healthcare workers, efficient learning methods like Virtual Reality (VR) are becoming increasingly important. We developed and tested a VR simulation for endotracheal suctioning.

The aim of this pilot study was to examine the VR simulation’s acceptance and increase of knowledge among participants. Furthermore, the effects of presence on acceptance and increase of knowledge were investigated.

A total of 51 students participated in the pilot study, using a quasi-experimental pre-post-test design. A modified Unified Theory of Acceptance and Use of Technology (UTAUT) and the Igroup Presence Questionnaire (IPQ) were used. Correlation and regression analyses were performed. Pre- and post-tests showed a significant increase of knowledge (p < 0.001). The correlation between presence and behavioural intention was highly positive (r = 0.52, p < 0.001).

Performance and effort expectancy are dominant effects on behavioural intention of using the VR simulation as an educational tool. The results indicate that a simulation which conveys a higher sense of presence is more likely to be accepted by learners. Regarding outcomes of presence on increase of knowledge, we found no significant correlation. Based on our study, we propose a design for a future mixed reality simulation with haptic elements and a plan on how to assess skills improvement.

Published: April 2021

In the current study, zinc–aluminum (Galfan) and zinc (galvanized) coatings were coated on steel sheets using the hot-dip technique. The effect of process parameters on the microstructure, corrosion behavior, hardness, and formability of the coatings was assessed. The results demonstrated that both the corrosion area and corrosion rate of the galvanized coatings were reduced by increasing the immersion time. In contrast, the process temperature did not affect the corrosion behavior. Furthermore, by prolonging the dipping time, the hardness of the coatings decreased. The Galfan coatings showed higher formability and the superiority of mechanical and corrosion properties of Galfan coatings over conventional galvanized coatings was indicated.

EDFA gain flattening optimization with long period fiber gratings in WDM system
Authors: Gandhi Divyangna , Gupta Shilpi , Gambhir Monika
Published: April 2021

This paper highlights a proposed optimized gain flatness technique for nonuniform gain spectrum of the erbium-doped fiber amplifier (EDFA) by introduction of long period fiber gratings (LPFG). In this analysis, EDFA gain spectrum has been evaluated between 1525 and 1600 nm with −20 dBm input signal power. Attenuation peaks of LPFG are optimized with a grating period of 240 µm and grating length of 30000 µm in the wavelength range of 1.1–1.8 μm, to compensate the peak gain of EDFA. Results have shown that EDFA peak gain of 35.94 dB is achieved at 1532.89 nm wavelength. This 35.94 dB peak gain is flattened up to 2.65 dB using long period fiber gratings. Also, less than ±0.3 dB gain flatness is achieved between 1528 and 1560 nm wavelength. The proposed less complex technique can be used to modify the grating parameters during fabrication in order to produce the loss peak at desired wavelength, which is efficient to flatten EDFA gain peak.

Published: April 2021

Objectives

Wolfram syndrome (WS) is a rarely seen autosomal recessive multisystem neurodegenerative disorder caused by mutations in the WFS1 gene.

Case Presentation

Three sisters with WS had diabetes mellitus (DM) at 4 years of age and optic atrophy. In addition, the first case had hearing impairment, and the second case had diabetes insipidus and urinary incontinence. Linagliptin was administered to the first case as add-on therapy to intensive insulin treatment 15 years after the onset of DM, and her insulin need showed a dramatic decrease. The third case had a remission phase one month after the onset of DM.

Conclusions

Even in cases with the same mutation, symptoms and findings may widely vary in WS. Remission of diabetes has rarely been reported in WS. Also, this report describes the first trial of a dipeptidyl peptidase-4 inhibitor in a patient with WS which provided a decrease in exogenous insulin need.
Delivery factors and neonatal thyroid hormone levels: a systematic review
Authors: Ramezani Tehrani Fahimeh , Nazarpour Sima
Published: April 2021

Postnatal thyroid hormone changes enable the neonate to be adapted for postnatal life. Several factors can affect this adaption. In this review, we summarized the studies that reported the association among the delivery factors and neonatal thyroid hormones and thyroid stimulating hormone. A comprehensive literature search was performed in PubMed, Web of Science, and Scopus up to March 2020, to identify the studies investigating the relationship between delivery factors, especially the mode of delivery and labor pain, and neonatal thyroid hormones and TSH. Finally, in this review study, of 157 articles obtained in the initial search, 25 eligible studies were reviewed. Various maternal, fetal/neonatal, and obstetric factors affected neonatal TSH and thyroid hormones. Among various influencing factors, mode of delivery, labor pains, and duration of labor have a strong relationship with neonatal thyroid hormones and need to be considered for interpretation of neonatal thyroid status. The majority of the studies revealed that vaginal deliveries (instrumental or natural) lead to higher levels of cord TSH compared to elective cesarean section. This can be explained by the increased secretion of catecholamine during labor. It has been suggested that blood TSH and thyroid hormone levels are affected by perinatal stress events such as maternal anxiety, labor pains, fetal distress, and other stimulants of the catecholamine response. These changes may act as the trigger to increase thyroid hormone levels for adapting of neonates in the first hours after birth. This assumption needs to be re-evaluated by performing comprehensive and well-designed studies.
Streptomerocyanine dyes
Authors: Mustroph Heinz
Published: April 2021

Dyes synthesized by condensation of e. g. 4-N,N-dialkylaminobenzaldehydes, 5-N,N-dialkylamino-2-thiophenaldehydes or 5-N,N-dialkylamino-2-furaldehydes, with open chain active methylene compounds have been given the labels merocyanine, neutrocyanine, methine or styryl dyes. All these classifications are misnomers. In terms of systematic nomenclature, their proper classification is as streptomerocyanine dyes. They are used in textile coloration and in dye diffusion thermal transfer printing (D2T2). Furthermore, they have been investigated for their potential as sensitizer dyes in dye sensitized solar cells (DSSC) and for photorefractive applications.

Authors: Kobzar Yaroslav , Fatyeyeva Kateryna , Chappey Corinne , Désilles Nicolas , Marais Stéphane
Published: April 2021

The number of researches on the ion exchange membrane has increased considerably in recent years showing interest in fuel cell technology for the automobile and portable applications. The most promising fuel cell technology for low-temperature operation (80 °C < T < 150 °C) uses a polymer membrane separating the anode and cathode compartments in an electrochemical cell. Polyoxadiazoles (PODs) belong to a class of heterocyclic polymers, which possess a number of unique properties, such as thermal, mechanical, and chemical resistance. In the present review, numerous ways of POD synthesis are discussed in relation to their functional properties. In addition, different approaches to the elaboration of POD-based composite membranes are discussed in details in order to reveal the structure/properties relationship.
Begräbnisdichtung im russischen Barock: Simeon Polockijs Threnodien
Authors: Klein Joachim
Published: April 2021

This article is about Simeon Polotskii’s voluminous lament of 1669 about the death of Mariia Il’inichna, the wife of tsar Aleksei Mikhailovich. The lament is analysed as a specimen of baroque court poetry and as a poetic cycle. Special attention is paid to its religious content. What are the lament’s principal ideas about death and the afterlife? How does it treat the central motif of contemptus mundi, the Christian contempt of life on earth? And how does it relate to the religious tenets of the Orthodox Church?
Diversity and divergence in bilingual acquisition
Authors: Meisel Jürgen M.
Published: April 2021

Bilingual settings are perceived as exemplary cases of linguistic diversity, and they are assumed to trigger cross-linguistic interaction. The rationale underlying this assumption is the belief that when more than one language is processed in a brain, this will inevitably affect the way in which linguistic knowledge is acquired, stored and used. However, this idea stands in conflict with results obtained by research on children acquiring two (or more) languages simultaneously. They have been demonstrated to be able to differentiate languages from early on and to develop competences qualitatively identical to those of monolinguals. These studies thus provide little evidence supporting the idea that bilingualism must lead to divergent grammatical development.

The question then is what triggers alterations of bilinguals’ grammars, especially of the syntactic core, possibly resulting in non-native competences. This has been claimed to occur in the acquisition of second languages, weaker languages of simultaneous bilinguals, or heritage languages. These acquisition types differ from first language development in that onset of acquisition of one language is delayed or that the amount of exposure to one language is reduced. I will argue that age at onset and severely reduced amount of exposure are potential causal factors triggering divergent developments, whereas bilingualism on its own is not a sufficient cause of divergence.

Published: April 2021

This study focusses on the production of biodiesel by reacting the heterogeneous based nano-catalysts with used cooking oil in the presence of methanol. The CZO nanoparticles (NPs) were synthesized by co-precipitation method and characterized by different techniques. Biodiesel was characterized by the gas chromatograph (GC) and Fourier Transform Infra-red Spectroscopy (FTIR). Optimum conditions for the maximum biodiesel yield (90%) were 0.2% (w/w) catalyst dose, 3:1 methanol to oil ratio, 50 °C reaction temperature, 150 min reaction time and 136 rpm stirring speed. The kinetic modeling and the thermodynamic factors like enthalpy (ΔH), activation energy (Ea), entropy (ΔS) and free energy (ΔG) were operated on all the data. Mean and standard deviation was used for analysis of data. The results indicate the maximum biodiesel yield under the optimum reaction conditions, which is promising to reduce the pollution such as air pollution and greenhouse effect for sustainable environmetal development.

Published: April 2021

Fragile X syndrome (FXS) is a neurodevelopmental disorder (NDD) characterized by intellectual disability, autism spectrum disorders (ASDs), and anxiety disorders. The disruption in the function of theFMR1gene results in a range of alterations in cellular and synaptic function. Previous studies have identified dynamic alterations in inhibitory neurotransmission in early postnatal development in the amygdala of the mouse model of FXS. However, little is known about how these changes alter microcircuit development and plasticity in the lateral amygdala (LA). Using whole-cell patch clamp electrophysiology, we demonstrate that principal neurons (PNs) in the LA exhibit hyperexcitability with a concomitant increase in the synaptic strength of excitatory synapses in the BLA. Further, reduced feed-forward inhibition appears to enhance synaptic plasticity in the FXS amygdala. These results demonstrate that plasticity is enhanced in the amygdala of the juvenileFmr1knock-out (KO) mouse and that E/I imbalance may underpin anxiety disorders commonly seen in FXS and ASDs.

Data on the diagnosis, natural course and management of immune checkpoint inhibitor (ICI)-related hypophysitis (irH) are limited. We propose this study to validate the diagnostic criteria, describe characteristics and hormonal recovery and investigate factors associated with the occurrence and recovery of irH. A retrospective study including patients with suspected irH at the University of Texas MD Anderson Cancer Center from 5/2003 to 8/2017 was conducted. IrH was defined as: (1) ACTH or TSH deficiency plus MRI changes or (2) ACTH and TSH deficiencies plus headache/fatigue in the absence of MRI findings. We found that of 83 patients followed for a median of 1.75 years (range 0.6–3), the proposed criteria used at initial evaluation accurately identified 61/62 (98%) irH cases. In the irH group (n = 62), the most common presentation was headache (60%), fatigue (66%), central hypothyroidism (94%), central adrenal insufficiency (69%) and MRI changes (77%). Compared with non-ipilimumab (ipi) regimens, ipi has a stronger association with irH occurrence (P = 0.004) and a shorter time to irH development (P < 0.01). Thyroid, gonadal and adrenal axis recovery occurred in 24, 58 and 0% patients, respectively. High-dose steroids (HDS) or ICI discontinuation was not associated with hormonal recovery. In the non-irH group (n = 19), one patient had isolated central hypothyroidism and six had isolated central adrenal insufficiency. All remained on hormone therapy at the last follow-up. We propose a strict definition of irH that identifies the vast majority of patients. HDS and ICI discontinuation is not always beneficial. Long-term follow-up to assess recovery is needed.

Authors: Pochintesta Paula
Published: April 2021

El presente trabajo indaga sobre formas de afrontar la viudez en el curso de vida. Se analizan diferencias de cohorte y género sobre el sentimiento subjetivo de soledad. Se estudian las actividades que se abandonaron, transformaron e iniciaron pos viudez y los tipos de apoyo social percibido. A partir de una estrategia metodológica cualitativa se realizaron entrevistas en profundidad a personas viudas del Área Metropolitana de Buenos Aires, Argentina. El análisis permitió reconstruir: diferencias según cohorte, posición y género frente a la viudez así como dimensiones espaciales y temporales referidas al sentimiento de soledad. Se evidencia que las mujeres cuentan con variados recursos y mayor apoyo emocional para afrontar la soledad, a diferencia de los viudos. La división sexual de tareas es notable en los viudos/as nacidos entre 1930 y 1959 mientras que, las cohortes posteriores a 1960 registran menor rigidez en este punto

Authors: Pasaribu Truly Almendo , Dewi Novita , Bram Barli
Published: April 2021

This article investigated how metaphors for COVID-19 were framed in a Catholic-based journal Thinking Faith. Data, consisting of 107 metaphors, were collected from the online journal and were analyzed within the Jesuit perspectives. Results showed that out of the 107 occurrences of metaphoric expressions for the pandemic, the source domains tend to have reflective and empowering aspects. The 12 main source domains of COVID-19 were war, drama, tools, natural forces, journey, manageable item, teacher, other living beings, darkness, pain, threat, and signs of the times. The coverage of Thinking Faith aimed to show the life-changing wisdom of the Gospel, Catholic Social Teaching, and Papal messages. Positive or neutral word choices of metaphors like teacher, drama, journey, manageable items, natural forces, and signs of the times managed to spark hopefulness for the journal readership. Meanwhile, the violence-related metaphors war, pain, and threat may appear to be discouraging. Overall, the metaphors used in the Jesuit online journal were contextually heartening

Published: April 2021

Periampullary carcinoma is a malignancy that appears around the vatteri ampulla. This malignancy can originate from the pancreas, duodenum, and distal choledochal duct. Duodenal cancer is a very rare case, only about 0.3% of the gastrointestinal malignancies. Reported cases are increasing with the increasing use of esophagogastroduodenoscopy. The most frequently found carcinomas of the duodenum include adenocarcinoma, carcinoid, lymphoma, and leiomyosarcoma. The symptoms of these carcinomas are often not specific so the diagnosis is often late, leading to a poor prognosis. Early diagnosis and proper therapy provide a good prognosis. The case reported here representeda 52-year-old woman presented with hematemesis melena, anemia, jaundice, epigastric mass, right hypochondrial pain, and weight loss. From the esophagogastroduodenoscopy, the mass was found to obstruct half of the duodenum lumen and bleeding, which was easily triggered, was observed in the second part of the duodenum. CT scan revealed a mass in the head of the pancreas with gall bladder hydrops and obstruction of the intra and extra-hepatic billier system. After a Whipple operation Laparotomy, the histology showed papillary adenocarcinoma duodenum. Patients then underwen chemotherapy with 5 fluorouracil regimen. Patient's clinical condition is currently improving and no complaint is conveyed by the patient.

La investigación tuvo como objetivo definir las mejores condiciones de extracción asistida por ultrasonido de los cálices de H. sabdariffa L. y la obtención de polvos microencapsulados, mediante secado por aspersión. Los extractos fueron analizados, considerando como variables: disolvente (agua y agua/etanol) y la relación temperatura/tiempo de extracción (25 ºC/60 min y 60 ºC/30 min). Para el secado se evaluaron las variables temperatura de entrada (150 ºC; 190 ºC) y la mezcla de encapsulantes goma arábiga (G) y maltodextrina (MD) (G40/MD60; G60/MD40). Los parámetros utilizados para el análisis fueron: rendimiento, pH, °Bx, composición química (fenoles y antocianinas totales, CLAE-EM) y capacidad antioxidante (DPPH). La mejor condición para la extracción de polifenoles resultó ser con agua:etanol (80:20), a 60 °C y durante 30 min. Se identificó la presencia de ácidos fenólicos, glicósidos de flavonoles y las antocianinas (delfinidina-3-sambubiósido y cianidina-3-sambubiósido), como las señales de mayor intensidad. Con el secado por atomización a 150 °C y con G60/MD40, se logró el mayor contenido de fenoles totales y antocianinas, sin embargo, la capacidad antioxidante se favoreció a 150 °C y con G40/MD60. Las micropartículas obtenidas podrían valorarse como materia prima para la elaboración de fitofármacos o alimentos funcionales, considerando su fácil manipulación, posible estabilidad y su valor antioxidante.

Over the past century, an increase in life expectancy has been observed in Russia and in the world. According to the United Nations, by 2100, the number of centenarians worldwide will reach 25 million. Despite the annual increase in the number of super-centenarians, this age group remains poorly understood.Aim. To estimate the prevalence of cardiovascular diseases (CVD) and the main risk factors among super-centenarians in Moscow.Material and methods. According to the register of long-livers in Moscow, 82 people aged 95 to 105 were included. Participants were examined at home.The history of life and the presence of chronic diseases was collected by participant words. To assess the state of cardiovascular system, an ultrasound of the heart and main arteries was performed.Results. Conventional CVD risk factors were the exception rather than the rule among study participants (smoking — 8 patients (9,8%), alcohol abuse — 4 (4,9%), obesity — 6 (7,3%)). Dyslipidemia was relatively widespread (n=37; 45,1%), however, there were no pronounced abnormalities in the lipid profile: the maximum increase in low-density lipoproteins was 5,6 mmol/L. The most common CVDs among the participants were hypertension (n=64; 78%), coronary artery disease (n=42; 51,2%), and heart failure (n=26; 31,7%); other diseases were much less common. The most common echocardiographic changes were left atrial dilatation (n=38; 74,5%), increased left ventricular mass, thickening of left ventricular posterior wall (n=24; 48%) and interventricular septum (n=51; 100%). Diastolic and systolic heart failure were not widespread among long-livers: 16 (32%) and 2 (3,9%), respectively. Despite a rather large number of atherosclerotic plaques in the common carotid and femoral arteries, the number of hemodynamically significant plaques was low (n=3; 4,6%). An intima-media thickening up to 1,0-1,1 mm was found.Conclusion. Long-livers in Moscow are characterized by a low prevalence of traditional CVD risk factors (with the exception of hypertension) and a fairly high prevalence of atherosclerotic CVDs, which are characterized by a subclinical course.
Polymorphism of ACE, AGT, AGTR1 genes as genetic predictors of hypertension
Authors: Elkina A. Yu. , Akimova N. S. , Shvarts Yu. G.
Published: April 2021

The genetic architecture of blood pressure (BP) includes more than 30 genes, the polymorphic variants of which cause phenotypic heterogeneity of BP. Given that a human genetic information is largely stable from birth, it can act as an early predictor of hypertension (HTN). Identification of polymorphic variants of genes associated with a high HTN risk may be one of the promising areas of early diagnosis and prevention of this disease. In addition, the availability of this data will make it possible to clarify the prognosis of patients already with HTN, as well as to personalize the treatment approach. The review analyzes the papers devoted to the molecular genetic basis of hypertension and identifies the possible role of gene polymorphism of the renin-angiotensin-aldosterone system in hypertension development. A large number of studies have revealed an association between HTN and polymorphic variants of the ACE, AGT, AGTR1 genes. In addition, polymorphism of these genes is involved in the development of atherosclerosis and related diseases, kidney and central nervous system disorders, and justifies the effectiveness of angiotensin-converting enzyme inhibitors in the treatment of HTN.

Extent of cardiac surgery aid has dropped significantly globally due to reallocation of health care resources due to COVID-19 pandemic.Aim. To evaluate the results of chosen management strategy for patients with coronary artery disease (CAD) and COVID-19 manifested in the early postoperative period after coronary artery bypass grafting.Material and methods. We present our experience of treating 19 patients with CAD and COVID-19 manifested in the early postoperative period after coronary artery bypass grafting. The main symptoms of COVID-19 in these patients were high-grade fever, severe general weakness, shortness of breath, and decreased blood oxygen saturation. Laboratory data showed significant increases in fibrinogen, C-reactive protein, ferritin, procalcitonin, and D-dimer levels. In all patients, according to the chest computed tomography, a picture of unilateral or bilateral multisegmental pneumonia in the form of ground-glass opacity areas was determined. The damaged lung area varied from 10% to 55%.Results. Patients were treated in accordance with the Russian guidelines, followed by transfer to continue therapy in specialized infectious diseases hospitals. Sixteen patients transferred to infectious diseases hospitals were subsequently discharged from in a satisfactory condition. Three patients died from various complications of COVID-19 (mortality rate, 16%).Conclusion. The development of new screening strategies, standard guidelines and protocols for the management of cardiac surgery patients in a pandemic will contribute to an earlier detection of COVID-19 and, accordingly, a timely change in treatment strategy.

The depressed text
Authors: Santos Diego A. H. Ortega dos , Banzato Claudio E. M.
Published: April 2021

North American writer David Foster Wallace wrote two short stories - The Planet Trillaphon As It Stands In Relation To The Bad Thing and The Depressed Person - that depict depression, in each one taking different yet complementary perspectives on this subject. Our aim is to analyze these texts and to discuss the role literature can have in regard to the apprehension of subjective experiences of others. Whereas the first text attempts to describe depression objectively, the second one describes the impossibility of doing so, focusing on literary techniques that create distressing subjective experiences in the reader, possibly resembling those felt by depressed persons. We suggest that literature might be helpful to comprehend some aspects of the experience of being depressed and that such an understanding may enrich psychiatric practice.
O nacionalismo hindu de Modi: autoritarismo e neoliberalismo na Índia
Authors: Santos Fabio Luis Barbosa dos
Published: April 2021

Resumo: O objetivo deste texto é discutir a convergência entre autoritarismo e neoliberalismo no contexto indiano, onde o partido no poder desde 2014 avança numa agressiva agenda nacionalista hindu (Hindutva). Inicialmente, é analisada a colonização da esfera pública por este nacionalismo religioso. Em seguida, é abordada a aceleração desse processo desde o início do segundo mandato de Narendra Modi em 2019. A terceira seção discute as bases de classe da política Hindutva. É avançada a hipótese de que a aceleração dessa agenda coloca um dilema para a classe dominante, uma vez que a radicalização inerente à dinâmica do nacionalismo hindu, ameaça a estabilidade social e a economia do país. Comprometida com esta política em função de interesses de classe, a grande burguesia não tem um projeto alternativo no momento, e arrisca se tornar prisioneira da engrenagem que ajudou a colocar em marcha.
Estado y autoritarismo en Argentina: el debate sobre la “nueva derecha”
Authors: Tzeiman Andrés
Published: April 2021

Resumen: El gobierno de la alianza Cambiemos bajo la presidencia de Mauricio Macri (diciembre 2015 - diciembre de 2019) provocó una intensa discusión en el campo intelectual argentino en torno de los modos de caracterizar a dicha experiencia política. En ese marco, las aproximaciones a la “nueva derecha” argentina se produjeron a partir de diferentes enfoques conceptuales. Al mismo tiempo, en sus respectivos análisis tales aproximaciones privilegiaron el abordaje de distintas dimensiones del fenómeno en cuestión. Recogiendo los aportes elaborados desde cada una de esas perspectivas y estableciendo un diálogo crítico con algunas de ellas, este artículo se propondrá llevar a cabo un análisis de las características generales de los cuatro años de gobierno de Mauricio Macri. De ese modo, se intentará arribar a una comprensión holística de esa experiencia política, concentrándose en su relación con los problemas del Estado y el autoritarismo.
Autoritarismo e crise da democracia no Brasil: entre o passado e o presente
Authors: Silva Sabrina Aparecida da
Published: April 2021

Resumo: O presente artigo busca refletir sobre a crise da democracia liberal e a ascensão de ideias autoritárias no Brasil a partir do golpe parlamentar de 2016, mas principalmente após o início do governo de Jair Bolsonaro em 2018. A ascensão de manifestações de direita e de extrema direita no País, na atual conjuntura, nos faz pensar sobre a complexa relação histórica entre Estado, autoritarismo e democracia no Brasil. Assim sendo, percebemos que a incipiente democracia liberal brasileira é sustentada por uma cultura política autoritária reprodutora de desigualdades, racismos, conformismos e violências. Nesse sentido, em oposição aos movimentos assinalados antidemocráticos, a democracia popular deve ser construída a partir de novos valores éticos, morais, políticos, filosóficos e econômicos, radical ao capitalismo e condizente com práticas político-pedagógicas capazes de fomentar novos sujeitos sociais.
Autoritarismo no Brasil do presente: bolsonarismo nos circuitos do ultraliberalismo, militarismo e reacionarismo
Authors: Araújo Maria do Socorro Sousa de , Carvalho Alba Maria Pinho de
Published: April 2021

Resumo: No presente texto, analisamos o autoritarismo como fenômeno contemporâneo, em âmbito mundial, a expressar-se, fortemente, no Brasil, nos marcos do capitalismo financeirizado. Alicerçadas na análise crítica de estudiosos da realidade brasileira, abordamos o bolsonarismo como expressão do autoritarismo no Brasil do Presente, constituído a partir da convergência do reacionarismo político-cultural, militarismo e ultraliberalismo. Para tanto, fundamentadas em Carvalho (2019), realizamos um recuo na história contemporânea brasileira, até a década de 1990, adentrando nos percursos do ajuste do país ao capitalismo mundializado. A partir desse marco histórico, discutimos a predominância das práticas voltadas ao ajuste financeiro, em meio aos embates pela democracia, com destaque para o Golpe 2016 e para a eleição de Jair Messias Bolsonaro, ápice do Golpe. Sustentamos a tese de que o bolsonarismo é uma expressão contemporânea do autoritarismo no Brasil, constituindo um dilema analítico e um desafio político.

Authors: Mariante Neto Flávio Py , Vasques Daniel Giordani , Stigger Marco Paulo
Published: April 2021

RESUMO As artes marciais mistas (MMA) são um esporte criado e modificado em associação com a mídia, cujo principal expoente são os eventos do UFC. O objetivo foi descrever e analisar o programa televisivo The Ultimate Fighter (TUF) Brasil. A pesquisa caracterizou-se como um estudo de caso que empregou uma etnografia de tela, de forma a descrever e interpretar sentidos ali produzidos. A análise do reality show TUF Brasil construiu três categorias: o programa, estrutura e regras; as técnicas, treinos, lutas e estratégias de esportivização; e os dramas pessoais/familiares e o processo de “humanização” do lutador. O programa impulsiona o processo de esportivização do MMA ao aliar elementos técnico-táticos das lutas com narrativas e dramas dos sujeitos.
SPHINCTEROTOMY ALONE VERSUS SPHINCTEROTOMY AND BILIARY STENT PLACEMENT IN THE TREATMENT OF BILE LEAKS: 10 YEAR EXPERIENCE AT A QUATERNARY HOSPITAL
Authors: FLUMIGNAN Victor K , SACHDEV Amit H , NUNES João P S , SILVA Pamela F , PIRES Lucca H B , ANDREOTI Mariana M
Published: April 2021

ABSTRACT BACKGROUND: Hepatobiliary surgery and hepatic trauma are frequent causes of bile leaks and this feared complication can be safely managed by endoscopic retrograde cholangiopancreatography (ERCP). The approach consists of sphincterotomy alone, biliary stenting or a combination of the two but the optimal form remains unclear. OBJECTIVE: The aim of this study is to compare sphincterotomy alone versus sphincterotomy plus biliary stent placement in the treatment of post-surgical and traumatic bile leaks. METHODS: We retrospectively analyzed 31 patients with the final ERCP diagnosis of “bile leak”. Data collected included patient demographics, etiology of the leak and the procedure details. The treatment techniques were divided into two groups: sphincterotomy alone vs. sphincterotomy plus biliary stenting. We evaluated the volume of the abdominal surgical drain before and after each procedure and the number of days needed until cessation of drainage post ERCP. RESULTS: A total of 31 patients (18 men and 3 women; mean age, 51 years) with bile leaks were evaluated. Laparoscopic cholecystectomy was the etiology of the leak in 14 (45%) cases, followed by conventional cholecystectomy in 9 (29%) patients, hepatic trauma in 5 (16%) patients, and hepatectomy secondary to neoplasia in 3 (9.7%) patients. The most frequent location of the leaks was the cystic duct stump with 12 (38.6%) cases, followed by hepatic common duct in 10 (32%) cases, common bile duct in 7 (22%) cases and the liver bed in 2 (6.5%) cases. 71% of the patients were treated with sphincterotomy plus biliary stenting, and 29% with sphincterotomy alone. There was significant difference between the volume drained before and after both procedures (P<0.05). However, when comparing sphincterotomy alone and sphincterotomy plus biliary stenting, regarding the volume drained and the days needed to cessation of drainage, there was no statistical difference in both cases (P>0.005). CONCLUSION: ERCP remains the first line treatment for bile leaks with no difference between sphincterotomy alone vs sphincterotomy plus stent placement.

Authors: Prasanna Naibi Shrungeshwara , Gowda Vinita
Published: April 2021

Abstract—A new gesneriad species, Didymocarpus vickifunkiae is described here from the Indo-Burma biodiversity hotspot. The new species is morphologically similar to D. aureoglandulosus, but differs from it in having a corolla tube with indumentum,
eglandular and ovate to oblanceolate bracteoles, slightly broader calyx lobes, and a bearded anther. We provide a detailed morphological description of the newly described species along with images and compare it with species that are morphologically similar to it. Here, we also lectotypify
D. aureoglandulosus and provide a brief history on its collection and taxonomy. Finally, we provide a dichotomous identification key for all the Didymocarpus species from Mizoram, India.
Collecting Duct Na+/K+-ATPase Activity Is Correlated with Urinary Sodium Excretion in Rat Nephrotic Syndromes
Authors: DESCHE[Combining Circumflex Accent]NES GEORGES , DOUCET ALAIN
Published: April 2021

In puromycin aminonucleoside (PAN)-treated nephrotic rats, sodium retention is associated with increased Na+/K+-ATPase activity in the cortical collecting ducts (CCD). This study was undertaken to determine whether stimulation of Na+/K+-ATPase in the CCD is a feature of other experimental nephrotic syndromes, whether it might be responsible for renal sodium retention, and whether it is mediated by increased plasma vasopressin levels or activation of calcineurin. For this purpose, the time courses of urinary excretion of sodium and protein, sodium balance, ascites, and Na+/K+-ATPase activities in microdissected CCD were studied in rats with PAN or adriamycin nephrosis or HgCl2 nephropathy. The role of vasopressin and calcineurin in PAN nephrosis were evaluated by measuring these parameters in Brattleboro rats and in rats treated with cyclosporin or tacrolimus. Despite different patterns of changes in urinary sodium and protein excretion in the three nephrotic syndrome models, there was a linear relationship between CCD Na+/K+-ATPase activities and sodium excretion in all three cases. The results also indicated that there was no correlation between proteinuria and sodium retention, but ascites was present only when proteinuria was associated with marked reduction of sodium excretion. Finally, the lack of vasopressin in Brattleboro rats or the inhibition of calcineurin by administration of either cyclosporin or tacrolimus did not prevent development of the nephrotic syndrome in PAN-treated rats or stimulation of CCD Na+/K+-ATPase. It is concluded that stimulation of Na+/K+-ATPase in the CCD of nephrotic rats might be responsible for sodium retention and that this phenomenon is independent of proteinuria and vasopressin and calcineurin activities.
