Authors: Montalvo Carlos Mauricio Martínez , Gutierrez Laura Catalina , Perez Carolina , Delgado Harrison Herrera , Barrios Paula Corinna Martinez
Published: January 2021

Abstract Rapidly progressive glomerulonephritis is a medical emergency, with mortality around 20%. It is characterized by crescent glomerulonephritis and progressive loss of kidney function, hematuria, and proteinuria. Its classification is given by immunofluorescence detection of antibodies against glomerular basement membrane (Anti-MBG), immunocomplexes, or pauci-immune pattern. Its etiology should be based on clinical findings, immunological profile, age, sex, and histopathological characteristics. We present a case of a 27-year-old woman with symptoms consistent with rapidly progressive glomerulonephritis and biopsy findings of a full-house kidney nephropathy, with an early fatal outcome. An association of low incidence, as it is a case with a full-house pattern, and an autoimmune profile for negative systemic lupus erythematosus makes this a rare case. ANCA-associated vasculitis with full-house kidney disease was diagnosed, an unusual condition with up to 3% presentation and few reports in the literature, highlighting the importance of its reporting and contribution to the literature.
Diagnosis of alveolodental ankylosis in unerupted canines: one of the answers to why the canine does not come
Authors: Consolaro Alberto , Hadaya Omar , Cardoso Mauricio de Almeida
Published: January 2021

ABSTRACT Introduction: Teeth frequently fail to erupt and situations arise that prevent the canines from reaching the occlusal plane. Objective: Discourse about the three situations in which the canine does not reach the occlusal plane, and remains unerupted; and at the same time, point how to make a safe diagnosis of alveolodental ankylosis - one of the three causes -, based on tomography. Conclusions: Ankylosis occurs in impacted teeth by atrophy of the periodontal ligament, including the epithelial rests of Malassez. The tomographic signs of alveolodental ankylosis in unerupted canines are the interruption of hypodense periodontal space, discontinuity of the lamina dura and its continuity with the root surface, which gradually loses its regular shape.

Published: January 2021

ABSTRACT Objective: The aim of this study was to evaluate the attractiveness of different types of esthetic orthodontic wires by laypeople and dentists. Methods: Five different types of orthodontic wires were evaluated: three esthetic wires (Teflon-coated, epoxy resin-coated and rhodium-coated wires), and two metallic wires (stainless steel and NiTi), as control. Monocrystalline ceramic brackets were installed in the maxillary arch of a patient presenting good dental alignment. The five evaluated wires were attached to the orthodontic appliance with an esthetic silicone elastic and photographed. The photographs were evaluated by 163 individuals, 110 dentists and 53 laypeople. The data were statistically evaluated by two-way ANOVA and one-way ANOVA, followed by Tukey tests. Results: There was a statistically significant difference in the attractiveness among the wires evaluated; the most esthetic was the rhodium-coated wire, followed by the epoxy resin-coated wire and, finally, the Teflon-coated wire, with no significant difference from the stainless steel and NiTi control archwires. There was no significant difference between the groups of evaluators. Conclusion: The most attractive was the rhodium-coated wire, followed by the epoxy resin-coated wire and, finally, the least attractive wire was the Teflon-coated wire, without statistically significant difference to the stainless steel and NiTi wires, used as control.

Published: January 2021

ABSTRACT Objective: To evaluate different concentrations of Galla chinensis extract (GCE) added to poly(methyl methacrylate) (PMMA), which is widely used for fabrication of removable orthodontic appliances, regarding the effectiveness of this herbal extract on antimicrobial effect and flexural strength of PMMA. Methods: Acrylic resin samples containing 0.4%, 0.8% and 1.6% GCE were prepared. Flexural strength was investigated via three-point flexural strength test for the 15 acrylic resin blocks of each concentration. Disk diffusion test was used to evaluate antibacterial effects of incorporating the same concentrations of GCE into acrylic resin. All these three groups were compared with the control group, with no added GCE, regarding flexural strength and antibacterial properties. Results: Comparison of flexural strength between the three study groups and the control group showed significant differences between the groups (P=0.018). However, there was no significant difference between the groups containing GCE. There were significant differences in antimicrobial activity between the four groups (P=0.026). Conclusion: Within the limitations of this study, it is suggested that incorporation of GCE into PMMA would be beneficial for antimicrobial activity and flexural strength of PMMA, but further studies on other physical properties and antimicrobial effects on other bacterial strain would be beneficial prior to clinical investigations.

Published: January 2021

ABSTRACT Introduction: Invasive cervical resorption (ICR) is a relatively rare type of ERR (External Root Resorption), in which a localized resorption begins in the cervical area of the tooth, below the epithelial junction and above the ridge crest. Objective: Describe the clinical case of an 11-year-old boy with no dental trauma history, presenting moderate crowding and ectopic eruption of the maxillary right central incisor. He had been undergoing orthodontic treatment elsewhere, and his family was dissatisfied with the results. Description: A new treatment was indicated, which included rapid maxillary expansion followed by extraction of four premolars. During routine panoramic evaluation, a radiolucid image was detected and a periapical radiograph was requested. At this point, an ICR of the maxillary right central incisor was found. The treatment was cautiously finalized and despite the use of light forces, central incisor was severally compromised by ICR and was therefore extracted. Conclusion: This clinical example discusses the importance of routine radiographs for the early diagnoses of ICR.

Published: January 2021

Dialogue is a very active area of research currently, both in developing new computational techniques for robust dialogue systems and in the active fielding of commercial conversational assistants such as Apple's Siri and Amazon's Alexa. This article argues that, while current techniques can be used to design effective dialogue‐based systems for very simple tasks, they are unlikely to generalize to conversational interfaces that enhance human ability to solve complex tasks by interacting with artificial intelligence reasoning and modeling systems. We explore some of the challenges of tackling such complex tasks and describe a dialogue model designed to meet these challenges. We illustrate our approach with examples of several implemented systems that use this framework.

Managing climate change transition risks: another potential role for civil engineers
Authors: Vercruysse Julian , Yates Kim , Stronati Davide
Published: January 2021

In addition to the physical risks of climate change, civil engineers also need to consider the transition risks involved in moving towards net zero greenhouse gas emissions. These include enhanced reporting obligations, stigmatisation of polluting industries and shifts in consumer preferences. This paper reports on a study into the potential role of civil engineers in mitigating transition risks, using London’s Heathrow airport expansion project as a case study. It concludes that while transition to a net zero economy will create a window of opportunity for civil engineers, additional skills will be needed for them to play a major role.

Published: January 2021

Aluminium (Al)-based metal matrix composites were developed with titanium carbide (TiC) and boron carbide (B4C) materials as reinforcement. The weight percentages of titanium carbide (1.5%) and boron carbide (0.5%) powder were maintained throughout the process of composite development. Composite process parameters such as powder compaction pressure, sintering temperature and time were varied in different combinations. The prepared composites were mechanically evaluated and metallurgically investigated for their quality. Further, the samples were subjected to electrochemical analysis to study their behaviour in 3.5% sodium chloride (NaCl) solution. From the experimentation, the corrosion potential and current density were measured. Subsequently, the corrosion rate (mm/year) of the material was calculated through its Tafel plot. The composite processed at a sintering temperature of 630°C for a duration of 135 min had higher corrosion resistance, with a minimum corrosion rate of 1.699 mm/year. The electrical resistance also increased over the exposed surface with a minimum current density of 0.15 mA/cm2. Scanning electron microscopy and energy-dispersive spectroscopy (EDS) were used to determine the metallurgical quality of the exposed surface. The oxide formation was observed on the exposed surface in the process of corrosion. The element aluminium and oxygen were found on the surface which denotes that the Aluminium oxide formed on the exposed surface. From the results, a discussion is presented confirming the influence of composite powder processing parameters.

Published: January 2021

The use of recycled coarse aggregate (RCA) in natural aggregate concrete is a sustainable solution to the problem of solid waste worldwide. The effects of RCA gradation, RCA content, fly ash content and water–cement ratio (w/c) on mechanical properties of RCA are studied in this paper. The stress–strain curves of each specimen under 28 days axial loads were obtained by experiments. Through the stress–strain curves of each specimen, the effects of the above four factors on the maximum strain, ultimate strain, elastic modulus and toughness index of RAC were analyzed, and the optimal selection of the four factors were determined. Mathematical models of strength and four factors were established by fitting the experimental data. Finally, the RAC’s hydration failure mechanism with different RCA contents was studied by scanning electron microscopy. The test results show that: influence degree of the four factors on the compressive strength of RAC is: w/c > RCA content > RCA gradation > fly ash content. Based on a comprehensive analysis of compressive strength, peak strain, ultimate strain, elastic modulus and toughness index, it is recommended that RCA gradation is 5–20 and 5.0–31.5, RCA content is 50–70% and fly ash content is 20%.

Published: January 2021

Objective: health judicialization is a multifaceted phenomenon; thus, it is necessary to identify what are the factors that cause this phenomenon in Brazilian scientific literature. Methods: it was conducted an integrative literature review, based on an exploratory-descriptive and bibliographic study of 101 publications available in Capes database. The search used 5 descriptors: judicialization and health and Brazil; health judicialization and law; judicialization and health and causes; judicialization and health and consequences; and judicialization and the right to health. Results: of a corpus of 101 articles, the authors selected 30, which were organized into three categories based on their theme: 14 articles discussed the judicialization of pharmaceutical assistance; 10 articles addressed the judicialization of the right to health; and 6 articles discussed judicialization with emphasis on management practices. Conclusion: Brazilian intellectual production is still incipient to identify and systematize the determinants of health judicialization. However, it was possible to have a preliminary understanding of the main themes, which were divided into three categories: the judicialization of pharmaceutical assistance, the judicialization of the right to health, and the judicialization and management practices.
Análise da capacidade jurídica dos pacientes idosos no Brasil a partir do referencial dos Direitos Humanos
Authors: Paranhos Denise Gonçalves de Araújo Melo
Published: January 2021

Objective: the article discusses the legal capacity of elderly patients from the human rights perspective and debates about the inadequacy of Brazilian legislation to assess the decision-making capacity and therefore leading to the mitigation of autonomy. Methods: the theoretical and documentary study conducted was based on Albuquerque's research on legal capacity and human rights; on the principles of the Convention on the Rights of Persons with Disabilities and the Inter-American Convention on the Protection of the Human Rights of Older Persons; and the Brazilian regulation of the Civil and Civil Procedure Codes on guardianship. Results: the method for assessing the legal capacity in Brazil is dissociated from the international paradigm because the assessment is based on the measurement of mental deficiencies or disorders, and not the ability to make specific decisions. Conclusion: elderly patients can be active protagonists of their therapy if their autonomy is promoted through the appropriate decision-making support to still be applied in Brazil.

Published: January 2021

Objective: to analyze the lawsuits related to chloroquine and hydroxychloroquine, according to indications and records at the National Health Surveillance Agency (Anvisa) as well as in the Clinical Protocols and Therapeutic Guidelines (PCDT) considering the diseases that motivated the claims, under the view of the bioethics for off-label use. Methodology: a documentary, exploratory-descriptive, transversal, quantitative study. The hydroxychloroquine and chloroquine lawsuits in the last 20 years in Minas Gerais were analyzed. Descriptive analysis was performed by considering the following variables: disease; ICD-10; medicines; year of incorporation into the specialized pharmaceutical assistance component (CEAF); and year of the lawsuit. SPSS® software version 19 was used to analyze the data. Results: the corpus of 155 processes analyzed, 148 (95.5%) presented demand for 400mg hydroxychloroquine and 7 (4.5%) for 250mg chloroquine. The analyzed drugs were registered with Anvisa and off-label use was found in 8.1% for hydroxychloroquine and 14.3% for chloroquine. Discussion: the judicial demands for hydroxychloroquine and chloroquine were related to their indications registered in the package leaflet and within the PCDT. However, the presence in the study of its off-label use demonstrated that the Judiciary grants the claims, bringing bioethical implications by impacting the principles of autonomy, non-maleficence, beneficence, and justice. Conclusion: the judicialization of off-label medicine interferes in the planning, execution, and financing of public health policies, in addition to causing citizen exposure to unknown risks, when using medicines with indications not supported by scientific evidence, by Anvisa, and by the production industry itself of the medicine.

Microseismic Evidence for Bookshelf Faulting in Western Montana
Authors: Smith Ellen M. , Martens Hilary R. , Stickney Michael C.
Published: January 2021

One of the most seismically active regions in the United States, located hundreds of kilometers inland from the nearest plate boundary, is the Intermountain Seismic Belt (ISB). The 6 July 2017 M 5.8 earthquake occurred 11 km southeast of Lincoln, Montana, within the ISB. This was the largest earthquake to rupture in the state of Montana since the 1959 M 7.3 Hebgen Lake earthquake. We use continuous seismic data from the University of Montana Seismic Network, the Montana Regional Seismic Network, and the U.S. Geological Survey to investigate the Lincoln aftershock sequence and to evaluate crustal stress conditions. We manually picked P- and S-wave arrival times, computed 4110 hypocenter locations and 2336 double-difference relocations, and generated focal mechanisms for 414 aftershocks (12+ polarities) in the 2 yr following the mainshock. Based on the alignment of aftershocks, we infer that the mainshock occurred on a north–northeast-trending left-lateral strike-slip fault. The orientation of the fault is unexpected, given that it strikes nearly perpendicular to the prominent Lewis and Clark line (LCL) faults in the area. Although most aftershocks concentrate near the mainshock, several distinct clusters of microseismic activity emerge along subparallel faults located primarily to the west of the mainshock. The subparallel faults also exhibit left-lateral strike-slip motion oblique to the LCL. We postulate that the aftershocks reveal the clockwise rotation of local-scale crustal blocks about vertical axes within a larger, right-lateral shear zone. The inferred block rotations are consistent with a bookshelf-faulting mechanism, which likely accommodates differential crustal motion to the north and south of the LCL region. The tension axes of well-constrained focal mechanisms indicate local northeast–southwest extension with a mean direction of N60°E.

Descriptive statistics, t-test and correlation analyses were used for data analysis. Participants’ psychological resilience was at mid-level, while the SCS self-confident approach and seeking social support sub-dimensions were at high and low level respectively. The athletes’ psychological resilience and stress coping strategies differed significantly according to gender. There was a positive and low significant correlation between experience and psychological resilience, in contrast a to negative and low significant correlation found between experience and helpless approach SCS sub-dimension. Middle and positive correlation was observed between age and psychological resilience. Finally, there were positive and middle significant correlations between psychological resilience and self-confident approach and optimistic approach, and a negative and middle significant correlation between psychological resilience and helpless approach SCS sub-dimensions.
A Weight Based Feature Extraction Model on Multifaceted Multimedia Bigdata Using Convolutional Neural Network
Authors: Maddumala Venkata Rao , R Arunkumar
Published: January 2021

This paper intends to present main technique for feature extraction on multimeda getting well versed and a challenging task to handle big data. Analyzing and feature extracting valuable data from high dimensional dataset challenges the bounds of measurable methods and strategies. Conventional techniques in general have less performance while managing high dimensional datasets. Lower test size has consistently been an issue in measurable tests, which get bothered in high dimensional information due to more equivalent or higher component size than the quantity of tests. The intensity of any measurable test is legitimately relative to its capacity to lesser an invalid theory, and test size is a significant central factor in producing probabilities of errors for making substantial ends. Thus one of the effective methods for taking care of high dimensional datasets is by lessening its measurement through feature selection and extraction with the goal that substantial accurate data can be practically performed. Clustering is the act of finding hidden or comparable data in information. It is one of the most widely recognized techniques for realizing useful features where a weight is given to each feature without predefining the various classes. In any feature selection and extraction procedures, the three main considerations of concern are measurable exactness, model interpretability and computational multifaceted nature. For any classification model, it is important to ensure that the productivity of any of these three components isn't undermined. In this manuscript, a Weight Based Feature Extraction Model on Multifaceted Multimedia Big Data (WbFEM-MMB) is proposed which extracts useful features from videos. The feature extraction strategies utilize features from the discrete cosine methods and the features are extracted using a pre-prepared Convolutional Neural Network (CNN). The proposed method is compared with traditional methods and the results show that the proposed method exhibits better performance and accuracy in extracting features from multifaceted multimedia data.

Published: January 2021

The Arabic natural language process (ANLP) community does not have an automatic generator of questions for texts in the Arabic language. Our objective is to provide it one. This paper presents a novel automatic question generation approach that generates questions as a form of support for children learning through the platform QUIZZITO. Our approach combines the semantic role labelling of PropBank (SRL) and the flexibility of question models. It essentially relates to an approach of instantiation model of representation based on an analysis focused on the semantics.

In recent years strokes are one of the leading causes of death by affecting the central nervous system. Among different types of strokes, ischemic and hemorrhagic majorly damages the central nervous system. According to the World Health Organization (WHO), globally 3% of the population are affected by subarachnoid hemorrhage, 10% with intracerebral hemorrhage, and the majority of 87% with ischemic stroke. In this research work, Machine Learning techniques are applied in identifying, classifying, and predicting the stroke from medical information. The existing research is limited in predicting risk factors pertained to various types of strokes. To address this limitation a Stroke Prediction (SPN) algorithm is proposed by using the improvised random forest in analyzing the levels of risks obtained within the strokes. This research of the Stroke Predictor (SPR) model using machine learning techniques improved the prediction accuracy to 96.97% when compared with the existing models.

Breast cancer is one of the world's most advanced and most common cancers occurring in women. An early diagnosis of breast cancer offers treatment for it; therefore, several experiments are in development establishing approaches for the early detection of breast cancer. The great increase in research in the last decade in microarray data processing is a potent tool of diagnosing diseases. Based on genomic knowledge, micro-arrays have changed the way clinical pathology recognizes, identifies, and classifies the diseases of humans, particularly those of cancer. In this article, we examined microarray data for breast cancer with the k-means clustering algorithm, but it was hard to scale and process a large number of micro-array data alone. To this end, we use a chart to minimize the paradigm for evaluating microarray data on breast cancer. Moreover, the efficiency of the parallel k-means model is measured with the operating period, the scaling, and all runtime of the model.

Introduction: Exercise training with different intensity regulates metabolism at the cellular level by regulating the expression of genes involved in mitochondrial biogenesis in diabetic patients. The aim of this study was to evaluate the effect of 4 weeks of high intensity interval training on the expression of PGC-1α, CS and p-53 genes in the cardiomyocytes of obese male rats with type 2 diabetes.
Methods: The present study was an experimental one. Eighteen obese male diabetic rats were divided into three groups of six: high intensity interval training (HIIT), diabetic control (DC), healthy control (NC). Diabetes was induced in all groups except the healthy control group by streptozotocin (STZ) injection. After anesthesia, blood serum was obtained directly from their left ventricle and immediately extracted from their left ventricle. Plasma glucose was measured by glucose oxidase assay. To determine the expression of PGC-1α, CS and P-53 genes, PCR-Real time method and group comparison were used by one-way ANOVA test with application 8 version  graph pad prism at alpha level of 0.05.
Results: The increase in PGC-1α gene expression in HIIT group compared to DC (P = 0.0001) and NC (P = 0.001) groups was significant. Increased expression of CS gene in HIIT group was significant compared to DC (P = 0.0001) and NC (P = 0.009) groups. Decreased expression of P-53 gene in HIIT group compared to DC (P = 0.0001) and NC (P = 0.001) groups were significantly different. Weight and glucose were significantly reduced in the HIIT group.
Conclusion: The results showed that by increasing the PGC-1α, CS genes and decreasing the expression of P-53 gene in cardiomyocytes of obese diabetic rats, it improves the energy metabolism in diabetic patients due to mitochondrial deficiency and possibly it can improve diabetic cardiomyopathy.

Background: Subacute ruminal acidosis is one of the most important nutritional diseases in cattle. The consequence of feeding excessive amounts of rapidly fermentable carbohydrates in conjunction with inadequate fiber to ruminants leads to subacute ruminal acidosis. Cattles are at a high risk of developing SARA. The present research work was undertaken to study haemato-biochemical alterations in SARA affected cattle treated with different treatment regimens. Methods: Present work was done to study the efficacy of sodium bicarbonate powder, Azadirachta indica (Neem) dried leaves powder and Saccharomyces cervisiae (Yeast) in sub-acute ruminal acidosis (SARA) in cattle. Out of 148 cattle screened, 24 (16.22%) were diagnosed as SARA, 13 (56.52%) animals were in mid stage of lactation followed by early and late lactation (5 cases, 21.74% each). Result: After sodium bicarbonate treatment, animals showed changes in various haemato-biochemical parameters. However decreased neutrophils and ALT was also observed. After treatment of Azadirachta indica reduction in lymphocyte and eosinophil count was seen.
Relaciones interculturales: La experiencia del circo y su singularidad
Authors: Contreras-Salinas Sylvia , Ramírez-Pavelic Mónica
Published: January 2021

Este artículo busca apreciar la configuración de relaciones interculturales desde una perspectiva crítica. A este respecto, se considera que el circo es un buen ejemplo para precisar cuestiones que muchas veces quedan en la abstracción, e impiden la acción comunicativa y la implicancia en la generación de los mundos sociales. El objetivo fue describir las acciones comunicativas y las prácticas de ciudadanía que construyen los integrantes del circo Markoning. La metodología utilizada corresponde al enfoque cualitativo; específicamente, a un estudio de caso, el cual fue abordado a través del análisis del discurso. Los principales hallazgos ilustran los desafíos y señalan un escenario propicio para indagar acerca de cómo se van gestando las relaciones interculturales a nivel local, situado y cotidiano. Como conclusión, se menciona que la acción comunicativa permite reconocer la singularidad del circo, mientras que sus prácticas de ciudadanía dan cuenta de una legítima participación periférica en el espacio público.

This paper focuses on studying the inventory of the medicinal plants used in hepatitis care in Bobo-Dioulasso and evaluating their availability in local vegetation and their phytochemical properties. To achieve this objective, several approaches were developed which include: (1) an ethnobotanical survey among 111 traditional health practitioners (THP); (2) a dendrometric study to evaluate the abundance and spatial distribution of these species in DindÃ©rÃ©sso Classified Forest; and (3) an evaluation of polyphenolic compounds and antioxidant activity of the two most quoted species roots using three methods such as anti-DPPH*, anti-FRAP, and antiABTS. The results show that Entada africana and Combretum micranthum were the most quoted species among 40 species used in the treatment of liver disease. The availability study revealed that juvenile and adult individuals of E. africana are frequent in woody savannah, shrubby savannah, and grassy savannah. As for juvenile and adult C. micranthum individuals, they are only frequent in wooded savannah (RI<60%). These populations are therefore declining due to anthropogenic pressure. Phytochemical analysis reveal polyphenols contents of 37.91 and 20.71 mg EAG/100 mg respectively for C. micranthum and E. africana and flavonoids contents of 0.85 Â± 0.09 and 0.66 Â± 0.05 mg EQ/100 mg respectively for C. micranthum and E. africana. Finally, the results show that there is an anti-oxidant activity for the two species. There were about 198 and 13 Î¼mol EAA/g for the two species i.e., ABTS and DPPH, respectively. The results show that the antioxidant activity could partially justify the traditional use of this plant.
