Pelletizing and torrefaction increase biomass energy density, generating a more homogeneous fuel with lower moisture, enabling it to burn in equipment with high energy efficiency. This work evaluated the quality of pellets made from wood particles that had been densified and torrefied in an extruder-type system. Particles of the Pinus sp. wood were torrefied at 200, 250, and 300 °C for six minutes and then compacted to produce pellets. The physical, chemical, and mechanical properties of these pellets were evaluated and compared with standard ones. Torrefaction modified the pellets properties by increasing ash, fixed carbon, higher heating value, and the energy density, while reducing the volatile matter and equilibrium moisture content. The mechanical durability of the pellets was lower than that defined by the European, German, and American standards. The torrefaction pre-compaction route with torrefied particles at a temperature of 300 °C was the most efficient for energetic use, compared to the in natura biomass. The latter has negative aspects such as great variation in size (length and diameter) and density besides high moisture content.

Objetive: To evaluate the association between attitudes, health behaviors, and the use of tobacco and alcohol among nursing students.
Materials and method: Exploratory, descriptive and cross-sectional study conducted with 182 undergraduate nursing students in the countryside of São Paulo, Brazil. Sociodemographic Information Form, Alcohol Use Disorders Identification Test – C(AUDIT-C), Fagerström Test for Nicotine Dependence (FTND), Attitudes and Health Behaviors Questionnaire (AHBQ), and Patient Health Questionnaire – 2 (PHQ-2) were applied.
Results: More than half of the students showed appropriate health behaviors and positive attitudes. Approximately 50% of the participants had consumed alcoholic beverages in the last month. Experimental use of illicit drugs and smoking were also observed. In addition, students who reported excessive alcohol use presented a deficit in self-care.
Conclusion: The precariousness in health attitudes and behaviors identified in this study was associated with various patterns of psychoactive substance use. Thus, the results indicate the need for interventions aimed at promoting well-being and a healthy lifestyle in the university environment.
Flavia Costa. (2021). Tecnoceno. Algoritmos, biohackers y nuevas formas de vida
Authors: Penchansky María-Celina
Published: March 2023

¿Qué tienen en común la ya tan mencionada pandemia por coronavirus con la explosión nuclear en Chernóbil, la crisis financiera de 2008 y los incendios en el Amazonas? En el ensayo sociológico Tecnoceno. Algoritmos, biohackers y nuevas formas de vida (2021), la investigadora argentina Flavia Costa sostiene que estos sucesos forman parte de una serie de acontecimientos que marcan una nueva etapa a la cual denomina tecnoceno. Cabe señalar que la elección de esta terminología no es casual; recuperando los debates sobre la categoría de antropoceno, la autora se inclina por utilizar la idea de tecnoceno para referirse a una época marcada por el uso de tecnologías de alta complejidad que transforman la forma de relacionarnos con el mundo y ponen en riesgo a todas las especies que habitamos en él.

Analysis of gravity data for extracting structural features of the northern region of the Central Indian Ridge
Authors: Thanh Pham Luan , Prasad K.N.D.
Published: March 2023

In this study, structural lineaments and fracture zones of the northern region of the Central Indian Ridge have been determined using gravity data from XGM2019e_2159 global gravity model. In this scope, firstly, the edge detection performances of the gradient amplitude of the tilt angle (THDR), theta map (TM), improved local phase (ILP), and improved logistic (IL) methods have been evaluated on synthetic examples. The results show that the IL method effectively avoids false edges and produces high-resolution edges. Then, the methods are applied to the gravity anomaly of the northern region of the Central Indian Ridge. It has been determined that the most prominent structural lineaments observed over the region are in the NE-SW and NW-SE directions. These trends match reasonably with the significant trends of the Tilt depth solutions that show a depth range of 2.2 km to 7 km for different geological structures. In addition, the obtained results are compatible with the known fracture zones of the study area. The findings help us to improve our understanding of the structure and tectonic framework of the study region.
CONHECIMENTO CIENTÍFICO NA FORMAÇÃO DA CONCEPÇÃO DE MUNDO DOS ESTUDANTES:
Authors: Teixeira Lucas André , Azevedo Vinicius , Oliveira Sarah Arantes de Paula , Trindade Caio Azevedo
Published: March 2023

Este estudo tomou como objeto de pesquisa a relação entre a pedagogia histórico-crítica e o ensino de Sociologia. Trata-se de uma investigação que estabeleceu como objetivo principal a identificação e a análise da concepção histórico-crítica na pesquisa em ensino de Sociologia pela implicação dos conhecimentos científicos na formação da concepção de mundo dos estudantes da educação básica. O delineamento metodológico se deu pela realização de uma pesquisa bibliográfica, compreendida no estudo como técnicas e procedimentos para a constituição dos dados empíricos. Caracteriza-se como uma pesquisa teórico-empírica que, para além dos dados empíricos sistematizados, visou apresentar contribuições teóricas não apenas para o ensino de Sociologia, mas para o movimento coletivo de construção teórica da pedagogia histórico-crítica, defendendo a articulação marxista entre a epistemologia, a ontologia e a pedagogia na formação de uma concepção de mundo materialista histórica e dialética. As análises apontaram alguns limites no que tange à busca de unidade entre conteúdo e método no processo de conversão do conhecimento científico das Ciências Sociais em saber escolar. Embora a incorporação histórico-crítica no ensino de Sociologia tenha sido analisada tendencialmente como marxista, os limites observados indicaram um processo de identificação e escolha dos objetos de ensino da Sociologia reduzido ao plano factual-histórico, em detrimento de uma articulação epistemológica, ontológica e pedagógica, resultado que fragiliza a formação de uma concepção de mundo histórico-crítica nos estudantes.
O EXERCÍCIO DA DOCÊNCIA DIANTE DO PROCESSO DE "FAVELIZAÇÃO" DO ENSINO MÉDIO ESTADUAL NO RIO DE JANEIRO
Authors: Alves Rita de Cássia Gonçalo , Rangel Marilia da Silva
Published: March 2023

Este artigo discute a problemática da vulnerabilidade das práticas de exercício da docência e, consequentemente, do ensino-aprendizagem de adolescentes e jovens diante do regime de precarização da educação no Ensino Médio no estado do Rio de Janeiro, cujo processo histórico chamamos de “favelização”. A favelização da educação pública estadual, bem como as dificuldades enfrentadas pelos docentes para o exercício da prática pedagógica fazem parte um projeto institucionalizado de precarização do papel do Estado junto ao Ensino Médio público ofertado às camadas mais carentes da população do estado do Rio de Janeiro. Favelização do Ensino Médio é um “projeto” que tem suas raízes históricas no desenvolvimento desigual da educação, cujos seres mais afetados são as populações negras e as camadas populares; por esta razão precisa ser discutido e combatido na sua essência original – que é a educação básica. O artigo tem como metodologia de análise a pesquisa bibliográfica em fontes que tratam da experiência educacional e seus marcadores das desigualdades. Dados quantitativos públicos oferecidos por instituições pesquisa, teóricas e teóricos dos campos da Educação, Sociologia e Estudos Urbanos ajudam-nos a explicar este processo. Propomos que a resposta para o combate à favelização do Ensino Médio está no desenvolvimento de disciplinas e competências complementares desde a educação básica, visando a uma escola pública de qualidade que proporcione capacitação aos professores, equidade e integralidade de formação para todos e todas.
PROFESSORES E AUXILIARES DE CRECHE
Authors: Albernaz Jéssica Marques , Reis Dayse
Published: March 2023

O presente artigo problematiza a tensa relação entre professores e auxiliares de turma. Essa divisão de trabalho estabelecida legalmente prejudica o binômio cuidar-educar e impacta consideravelmente a qualidade do trabalho na primeira infância. Sustentar-se-á que existe uma indissociabilidade dessas funções, conforme orienta o currículo referência de Minas Gerais e todos os documentos norteadores da educação infantil. Esta análise documental tem como objetivo investigar o currículo referência de Minas Gerais a fim de apontar suas perspectivas sobre cuidar e educar na educação infantil, sublinhando as funções do professor e do auxiliar na creche. Na primeira parte apresentar-se-á um breve panorama da história da educação infantil e sua luta para legitimação como uma etapa da educação básica. Em seguida, examinar-se-á a realidade de professores e auxiliares de creche no município do sul de Minas Gerais a respeito da divisão administrativa do trabalho, comparando com o que o currículo referência de Minas Gerais considera ideal para a educação infantil. Espera-se encontrar um direcionamento da legislação para o fortalecimento da educação infantil como um direito, onde o cuidar e o educar não estão pautados em filantropia ou assistencialismo, mas em políticas públicas.
CONFLITOS ENTRE CORRENTES HEGEMÔNICAS E CONTRA-HEGEMÔNICAS NO CURRÍCULO

Published: March 2023

Nesta pesquisa, foi realizada uma análise de arquivo, tendo como objeto o Projeto Pedagógico do Curso (PPC) de um curso de licenciatura em ciências da natureza. A partir do referencial teórico da Educação Libertadora freireana, bem como outros referenciais críticos, e do referencial teórico-metodológico da Análise de Discurso franco-brasileira, buscou-se observar as condições de produção do discurso materializado no PPC. Por meio da análise, considerou-se que de seu interdiscurso são emergidos elementos como: articulação entre teoria e prática na formação docente; articulação entre ensino, pesquisa e extensão universitária; aproximação entre Universidade e Escola; pedagogia das competências. Por outro lado, alguns silenciamentos foram notados: filiações teóricas; jargões e lugares-comuns; discurso de equidade. Assim, concluiu-se que as perspectivas crítico-transformadoras não podem nem devem aparecer de maneira velada ou implícita num documento desta natureza. Em contrapartida, nesse movimento, é possível considerar o silêncio e a inconclusão presentes no discurso materializado no PPC justamente como pontos de deriva, de transformação e superação da lógica hegemônica.
“DA TERRA SAI UM CHEIRO BOM DE VIDA E NOSSOS PÉS A ELA ESTÃO LIGADOS”
Authors: Reis Diego dos Santos
Published: March 2023

Trata-se, nessa intervenção, de mobilizar a categoria de “amefricanidade”, criada por Lélia Gonzalez, para reposicionar os debates sobre políticas curriculares e a produção dos currículos nos cotidianos de práticas educativas comprometidas com as lutas contra as desigualdades e discriminações raciais. A análise, que tem por esteio os processos de resistência à colonialidade em Améfrica Ladina e os enfrentamentos levados a cabo pelo Movimento Negro, desdobra as implicações da concepção amefricana do currículo, em consonância às Leis 10.639/03 e 11.645/08, tematizando limites, desafios e possibilidades decorrentes desse dispositivo jurídico e político-epistêmico. Busca-se, desse modo, refletir como a “descolonização dos currículos” impõe redimensionar o vocabulário, os imaginários e as práticas que se refletem em sua construção política, além do modelo parametrizado por categorias que não expressam a realidade dos territórios e das experiências dos sujeitos racializados na diáspora.
Revisitando el orden zoomorfo: diseño decorativo en las riberas del Titicaca
Authors:   Universidad de Buenos Aires, Argentina, Isidoro Alberto Martín
Published: March 2023

A special kind of wood architecture order for retables and pulpits is developed around the Lake Titicaca. It is possible, to consider it as a part of a regional itinerant aesthetic, i.e., zoomorphic order. Datable between the end of 17th century and 18th century, it is one of the stylems that define hybrid baroque, probably inspired in engraved sources. The above mentioned order already had been identified and documented 40 years ago by the architects José de Mesa and Teresa Gisbert. Nevertheless, to think again about this topic can throw new light to what was already said, extending certain aspects. I especially want to lead to the end one of their hypotheses: This column is also a mannerist survival since it is inspired by treatise writers, so Palladio in his book ‘Quarter of Architecture’ treats Nerva’s temple, on chapter VIII, showing a capital with horses, and Sagredo has a capital with heads of sheeps. This conjecture is founded on the traffic of architecture treatises, but especially on the idea of inspiration and not a faithful reproduction of the engraving sources, since there was only a few holders of those books. On the other hand, it was more possible to have copies in diverse degrees due to their transformations because of transposition process. With that idea, I allow myself to advance on the topic from a new perspective. It is to consider the contribution of a contemporary referrer, already well known and with a great influence in continental Europe in the beginning of the development of these hybrid works: Jean Bérain the Elder (1640–1711). In his repertoire, we find his proposals on variants of capitals of columns and pilasters. Here the arabesque subordinates the acanthus and there is a wide development of fantastic animals or semihuman beings of a classic mythological character – that shows us an evident mannerist influence. I will focus on the research of this order, in two cases: gospel altarpiece in Pomata’s transept and Yunguyo’s major altar and pulpit, two Dominican churches in the former colonial Chucuito in Peru.
Más allá del Pacífico. Piezas de Oriente en los templos de Cundinamarca, Boyacá y Santander (Colombia)
Authors:   Departamento de Didáctica de las Ciencias Sociales de la Universidad de Granada, Sánchez Guadalupe Romero
Published: March 2023

The article presents the research on oriental elements of church furnishing, which constitute the heritage of missionary and evangelization churches (iglesiasdoctrineras) in New Granada of the early 17th century. Thanks to extensive archival sources stored in Archivo General de la Nación de Colombia (Colombia, Bogota) as well as Archivo General de Indias (Spain, Seville) it is possible to demonstrate the existence of numerous objects of oriental origins. Oriental objects came to the area of Tierra Firmevia a sea route connecting Seville with territories belonging to the Spanish crown in America (Carrera de Indias), which was used yearly by an Indian fleet, and owing to a transpacific route connecting Spanish dominions in Asia with territories of New Spain. The latter route was called Galeón de Manila, Nao de China or Galeón de Acapulco. Twice a year, ships chose it to travel across the Pacific, ensuring communication between Spanish East Indies and American dominions of the crown. Oriental products and objects spread over the area of New Granada. Some of them became furnishing elements of modest missionary churches situated far from big colonial cities. Among the most important objects, one may find silk textiles, but there are also other objects (particularly fabric) of diverse character, whose presence in researched temples is confirmed by archival sources.
Traditions of the European basilica model in the sacred architecture of Colonial Latin America
Authors:   Faculty of Art History, University of Łódź, Poland Polish Institute of World Art Studies, Kubiak Ewa
Published: March 2023

El artículo aborda dos problemas: por un lado, la cuestión del funcionamiento del modelo de la basílica europea en las colonias de América Latina y por otro lado, la cuestión de la tradición y funcionamiento del atrio en la arquitectura colonial. Por basílica entiendo en este caso todas las iglesias – sin tener en cuenta sus proporciones – de tres naves en las que la nave principal está iluminada por ventanas ubicadas por encima de las naves laterales, bien en las mismas paredes o bien en la bóveda de la nave principal. El plano basilical es relativamente poco común en América Latina, mucho más frecuentes son proyectos más sencillos como la iglesia de nave única, a menudo con transepto, en ocasiones con una cúpula que acentúa el crucero. El esquema basilical en la arquitectura latinoamericana encontramos en primer lugar en realizaciones catedralicias. Otro grupo de templos donde a menudo se optó por este modelo constructivo son las iglesias conventuales, mayormente objetos en grandes núcleos urbanos que destacan por la presencia de construcciones de este tipo. Analizando la cuestión a gran escala, el terreno más importante para las realizaciones de forma basilical es Nueva España. La gran mayoría de este tipo de fundaciones, tanto catedralicios como conventuales, fue fundada en México. La segunda cuestión que parece interesante, es el tema de la existencia y funcionamiento del atrio en la arquitectura sacra de América Latina. El atrio como elemento arquitectónico de la iglesia está conocido en la arquitectura sacara europea desde la época paleocristiana, pero va desapareciendo en las realizaciones sacras europeas de épocas posteriores. La popularidad del atrio en América Latina puede explicar la específi ca situación social del Nuevo Mundo, que en los siglos XVI y XVII difería mucho de la situación en Europa, acercándose en los primeros años de la conquista más bien a la realidad de la época paleocristiana que a los mecanismos que formaban la sociedad renacentista. La principal misión, desde el punto de vista de la religión, era la evangelización de la inmensa populación indígena, la divulgación de la nueva fe. En este contexto el atrio resultó ser una herramienta muy útil para la evangelización, lo que le aseguró una gran popularidad.

Abstract The constant intensification of aquaculture has considerable increased the stress levels of farmed fish and, consequently, the number and intensity of diseases outbreaks. Thus, studies on fish immune response, especially regarding the interaction of fish leukocytes with potential pathogens and xenobiotics are of great importance in order to develop new prophylactic and curative strategies. We isolated leukocytes from the head kidney of Astyanax lacustris—an important Neotropical fish species for aquaculture and a potential model for Neotropical aquaculture research—using a Percoll centrifugation protocol. The isolated leukocytes were incubated with lipopolysaccharide (LPS), and the expression of genes IL-1β, IL-8, LysC, and LysG were measured. We assessed the phagocytotic activity of leukocytes using Congo red-dyed yeast, a novel and cost-effective protocol that has been developed in this study. The isolated leukocytes responded to LPS induction, exhibiting strong IL-1β and IL-8 upregulation, two of the most important pro-inflammatory interleukins for vertebrates immune reponse. The optimal concentration of yeast for the phagocytic assay was 106 cells mL-1, resulting in acceptable phagocytic capacity (PC) but without excess of yeasts during the counting process, ensuring a high precision and accuracy of the method. To the best of our knowledge, the present study is the first to investigate the in vitro gene expression and phagocytic activity of leukocytes isolated from A. lacustris. Our findings will serve as a reference for future studies on the immunology and toxicology of Neotropical fish.
Water-retention properties of xanthan-gum-biopolymer-treated soils
Authors: Chang Ilhan , Cho Gye-Chun , An Tran Thi Phuong
Published: March 2023

This study aimed to estimate the effects of the xanthan gum biopolymer on the wetting and drying processes of soils. Xanthan gum with different contents by the mass of dried soil was used to treat Jumunjin sand and sand-clay mixtures. The wetting and drying soil-water characteristics of xanthan-gum-biopolymer-treated sand were investigated using capillary rise open tubes and a Fredlund-type soil-water characteristic curve device, respectively. The results show that xanthan gum has a significant effect on controlling the movement of water in soil. The xanthan gum biopolymer shapes the drying soil-water characteristics of soil, and there is a non-linear relationship between the xanthan gum content and the soil-water characteristic parameters of the treated soils. Xanthan gum significantly reduces the capillary conductivity of soil down to 10−7–10−8 m/s for soil treated with 1.0% xanthan gum. Xanthan gum affects the capillary equilibrium process of water differently in wetting tests as well. Furthermore, the wetting results show the role of clay particles in the flow-controlling performance of xanthan gum.
Optical investigation of sol–gel-synthesized and spin-coated SiO2/TiO2 multilayers
Authors: Saravanan Sigamani , Dubey Raghvendra Sarvjeet , Subbarao Penjerla Srinivasa
Published: March 2023

In this work, silicon dioxide (SiO2)/titanium dioxide (TiO2) multilayer films were deposited on silicon substrates through the sol–gel spin-coating technique using the precursors titanium butoxide and tetraethyl orthosilicate. After the preparation, the various optical and morphological properties of the films were studied by using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and ultraviolet–visible (UV–Vis) spectroscopy. The XRD patterns showed intense diffraction peaks, which were found to correspond to anatase titanium dioxide and it matched well the standard Joint Committee on Powder Diffraction Standards file. The crystallite sizes of the prepared samples were calculated as 24 nm for three stacks of silicon dioxide/titanium dioxide thin films and 30 nm for five stacks of silicon dioxide/titanium dioxide thin films using Debye–Scherrer’s formula. The FTIR transmittance spectra confirmed Si–O–Ti vibrational modes at 800 and 960 cm−1 with related functional groups. A reflectance of 86% was measured by using UV–Vis spectroscopy. These dielectric multipliers will be useful in solar cells as backside reflectors for an improved light-harvesting mechanism.
Computational design exploration of a segmented concrete shell building floor system
Authors: Costa Eduardo , Oval Robin , Shepherd Paul , Orr John
Published: March 2023

The construction industry is responsible for nearly half of the UK's carbon dioxide emissions and the use of an extremely large volume of concrete – the world's most widely used man-made material – accounts for more than 7% of global carbon dioxide emissions. The scale of this problem spawned research to explore the potential for structurally efficient non-prismatic geometries to reduce the amount of concrete used in building elements substantially, thus also reducing their embodied carbon dioxide footprint. In particular, the research focused on segmented thin concrete shells as floor slabs, leveraging computational design and digital fabrication methodologies to automate their production off site. An important part of this research was the development of a computational framework for the design of thin concrete shells in order to make such a construction methodology accessible to building designers in practice. The framework combines solutions for parametric modelling, finite-element analysis, isogeometric analysis, form-finding and optimisation, along with embedded fabrication constraints specific to the project's automated manufacturing system. The application of the developed computational framework in the design of a 4.5 m × 4.5 m prototype is documented in this paper, illustrating how automating concrete construction can transform the industry towards net-zero.
Noninvasive Detection of iC3b/C3d Deposits in the Kidney Using a Novel Bioluminescent Imaging Probe

Published: March 2023

Significance Statement

Histologic quantification of complement C3 deposits in kidney biopsies provides prognostic information in patients with glomerulonephritis. Unfortunately, kidney biopsies are invasive procedures that cannot be performed regularly and only provide a snapshot of a small portion of one kidney at the time of sampling. We have developed a method to noninvasively detect specific C3 fragment deposition throughout both kidneys, using a monoclonal antibody targeting tissue-bound iC3b/C3d linked to a bioluminescent resonance energy transfer construct that emits near-infrared light. In a mouse model of glomerulonephritis, the probe detected iC3b/C3d in kidneys of live mice by bioluminescent imaging. This demonstrates that noninvasive imaging with an anti-iC3b/C3d probe can be used to monitor inflammation in the kidneys.
The impact of ICT on inter-organizational knowledge sharing for SMEs growth
Authors: Azyabi Naief
Published: March 2023

It is common knowledge that information and communication technologies (ICTs) have made continuous inroads in the knowledge management field; thus, this study is modeled to examine the impact of ICTs on inter-organizational knowledge sharing (IOKS) and its subsequent effect on the growth of small and medium-sized enterprises (SMEs). The study adopts a descriptive survey design, using the quantitative research approach. Using the simple random sampling technique, a web-based questionnaire was used to collect data from 187 respondents. Results showed that IOKS among SMEs is not carried out to a great extent, which means that it is not a common practice among SMEs. Findings showed that less than half of the SMEs used training programs, internship programs, research collaboration and workshops for IOKS. It further showed that IOKS enhances sales, productivity, profit, organizational assets and equity. This study provides evidence of how ICT systems/tools have been used in IOKS and their impact on the growth of SMEs.

Published: March 2023

Objective Develop and validate an ordinary meeting simulation template of the Municipal Health Council applied to students of cycle II of Elementary School.

Methods. Qualitative and descriptive research developed in two phases: construction of simulation scenario of ordinary meeting of the Municipal Health Council and validation by committee of experts who analyzed the representativeness and adequacy of the content. The scenario included the items: prebriefing, additional information about the case, scenario objectives, evaluation criteria (observers), scenario duration time, human and physical resources, instructions for the actors, context, references and debriefing. In order to be able to understand which items should be modified according to the evaluations of the experts, it was used as criterion that only items that had 80% or higher percentage of agreement between the experts for modification would be modified.

Results: There was agreement to modify the prebriefing in: additional information about the case (100%); learning objectives (88.8%); human and physical resources (88.8%); context (88.8%); and in the debriefing (88.8%). The prebriefing did not reach the level of agreement: evaluation criteria (66.6%), duration of the scenario (77.7%), instruction for authors (77.7%), references (77.7%), which were modified.

Conclusion. With the template developed and then validated by the committee of experts, it will be possible to develop in the classroom content related to the right to health and social participation in the scope of elementary education, as well as encourage engagement in important bodies for the maintenance of democracy, justice and social equity.
A rosszindulatú daganatos fájdalom kezelése gyógyszerekkel és idegblokádokkal
Authors: Embey-Isztin Dezső
Published: March 2023

A WHO szakértői 1986-ban fogalmazták meg a daganatos fájdalomcsillapítás alapelveit, amelynek lényege a kombinált gyógyszeres fájdalomcsillapítás, mert ez mindenütt kivitelezhető. Gyógyszeres fájdalomcsillapításra javasolt: minor analgetikum, gyenge opioid, erős opioid, és minden esetben úgynevezett adjuváns analgetikum. Kínzó daganatos fájdalom esetén azonnal erős opioid analgetikumot kell rendelni, nem szabad szenvedni hagyni a betegeket a gyengébb szerek kombinációjával. A gyógyszereket sohasem szükség esetére kell rendelni, hanem fix állandó dózisban, rendszeres időközönként. A korszerű kombinált gyógyszeres kezeléssel a daganatos betegek fájdalma körülbelül 80%-ban jól enyhíthető. Egyes daganatoknál speciális neurolyticus idegblokádokkal sokkal hatékonyabb fájdalomcsillapítást tudunk elérni.

Authors: Baran Gozde , Gelisin Ozlem , Babacan Yildiz Gulsen
Published: March 2023

Introduction – Methanol is a colorless and highly toxic liquid similar to ethanol in odor and taste. Methanol intake can lead to severe metabolic acidosis, loss of vision, permanent neurological damage, and death. Case report – We report a case of a 19-year-old female patient who had no known disease history. A large portion of her back was covered in spirits for back pain and kept on for 2 days. Cranial magnetic resonance imaging (MRI) on the 5th day showed hyperintense pathologic signal changes in the T2 sequence without contrast enhancement in the bilateral frontal corticalsubcortical regions and basal ganglia. Following neurological examination of the patient, she was found to have bradymimia, marked resting tremor, bradykinesia, and dystonia on the right upper and lower extremities. Our case is important because it is the only case where parkinsonism developed as a result of acute transdermal methanol intoxication.

Published: March 2023

A smart contract is a concept of computer protocols that helps to facilitate blockchain technology. This blockchain-based smart contract is a public ledger of all participating transactions. It is considered a self-executable application and contains predetermined rules. It also operates by decentralizing networks that are shared between all parties, and this execution of contracts between parties could be securely done without a middleman or a third party. With blockchain technology, developers could provide an efficient framework and ensure security issues. While the new blockchain has successfully been developed to prevent the problems of fraud and hacking, there is still a considerable risk concerning security and confidentiality. Therefore, we should not underestimate this matter. This study aims to review the potential risks that may take place on blockchain-based smart contracts. In addition, the options that may assist application developers in order to provide viable guidance, and to avoiding these security vulnerabilities.

Background: For the identification of arrhythmia and abnormal instances, researchers are examining the reliability of the interpretation offered by smartphone-based portable ECG monitors. The indicator of an unclear alteration in the electrical activity of the heart is a cardiac abnormality. As a result, its early and accurate identification can avoid myocardial infarction and even sudden cardiac death. Objectives of this study were to evaluate and validate the Spandan 12 lead ECG interpretation for accuracy in detection of the cardiac arrhythmias in comparison to the cardiologist diagnosis, and to evaluate the accuracy of the arrhythmia detection of Spandan ECG in comparison to the 12 lead ECG machine.
Methods: This cross-sectional study, non-randomised, single blinded and single-center study was carried out at Shri Mahant Indresh Hospital (SMIH), Dehradun, Uttarakhand, India from 1st August 2022 to 31st January 2023. All patients (n=312) visiting the electrocardiogram (ECG) room at the department of cardiology of the SMIH, Dehradun with the prescription of ECG screening during the study period were included in the study were included in the study.

Background: Salivary gland lesions are highly heterogenous group of disorder. There are no reliable criteria to differentiate benign from malignant lesions on clinical grounds, so histopathological evaluation is essential.
Methods: The present study was retrospective study carried out in the department of pathology, Government medical college, Surat from January 2015 to June 2020. Biopsies/specimens were fixed by 10% neutral buffered formalin and processed, embedded in paraffin and sections were cut and stained with hematoxylin and eosin stain. All the slides were reviewed by authors and re-staining of slides and fresh sections of tissue blocks were performed whenever required.
Results: Out of 80 cases, 22 were non-neoplastic, 45 were benign and 13 were malignant. In our study most common non neoplastic lesion was chronic sialadenitis. Most common benign lesion was pleomorphic adenoma. Most common malignant lesion was mucoepidermoid carcinoma. Most commonly involved gland was parotid gland. In parotid gland, most common lesions were benign. The overall sex incidence of salivary gland lesions in male was 45% and 55% in females with a male to female ratio of 1:1.2.
Conclusions: Thorough knowledge of morphology of salivary gland lesion is helpful in final diagnosis in predicting prognosis, typing, staging and grading of salivary neoplasms.
