Review of Diagnostic Radiology Imaging Modalities for Evaluating Skin Lesions Involving the Head and Neck
Authors: Ginat Daniel , Lotfian Golnaz
Published: November 2024

While skin lesions are apparent on clinical exam, diagnostic imaging is sometimes warranted to assess the local and distant extent of disease. CT imaging offers high-resolution anatomical detail and is particularly valuable in delineating deep-seated lesions, bone involvement, and assessing metastatic spread. MRI provides excellent soft tissue contrast and is indispensable for evaluating lesions in anatomically complex regions such as the head and neck. Ultrasound, on the other hand, offers real-time imaging, portability, and cost-effectiveness, making it an essential tool in the initial assessment and surveillance of superficial skin lesions. PET imaging, although less commonly employed for primary skin lesion evaluation, plays a crucial role in detecting metastatic disease and assessing treatment response in advanced-stage malignancies. Each modality has its advantages and limitations, and the choice of imaging technique depends on factors such as lesion characteristics, clinical indication, and availability of resources. Integration of multiple imaging modalities with clinical and histopathological correlation enhances diagnostic accuracy and facilitates optimal patient management. This review highlights the roles of CT, MRI, PET, and ultrasound in the comprehensive evaluation of skin lesions, with a focus on their respective indications, advantages, and utility in clinical practice.
Post – Stroke Seizures: A Comprehensive Review of Epidemiology, Pathophysiology, Risk Factors, Clinical Spectrum and Outcomes
Authors: Ravikumar Aparajit , Bhoopathy R. M. , Laha Anirban , Mani R.
Published: November 2024

Post – stroke seizure (PSS) represent a significant and often notable complication following cerebrovascular damage due to infarct and hemorrhage, that can affect stroke recovery and the long-term prognosis. This review aims to delineate the epidemiology, clinical spectrum, and outcomes of PSS through an extensive analysis of current literature. It is classified into two types based on the onset of occurrence following stroke, early-onset, occurring within the first seven days following stroke, and late-onset, which manifest beyond seven days after stroke. Early seizures have the same clinical course as acute symptomatic seizures, they rarely recur or require long – term antiepileptic drugs (AED’s). Conversely, late seizures are associated with a risk of recurrence similar to that of unprovoked seizures in a patient with a focal lesion, thereby requiring long – term administration of AED’s. The pathophysiology of PSS is multifaceted and involves a complex interplay of acute metabolic disturbances, excitotoxic neurotransmitter release causing neuronal hyperexcitability, and chronic neural network reorganization. Key risk factors include the type, location, and severity of the stroke, with cortical and hemorrhagic strokes being more prone to induce seizures. Clinically, PSS manifests predominantly as focal seizures, with some cases progressing to generalized seizures or status epilepticus. PSS is associated with poorer functional recovery, reduced quality of life, cognitive decline, increased morbidity, and a higher risk of developing epilepsy. Preventing stroke and PSS remains a cornerstone of any strategy to achieve optimal brain health. Early identification and appropriate management of PSS are crucial for minimizing their impact and thereby improving long – term outcomes for stroke survivors. Effective management includes the use of AED’s, secondary prevention strategies, comprehensive rehabilitation, and regular monitoring. Continued research and individualized treatment plans are essential to develop better preventive, diagnostic, and therapeutic strategies for PSS, ultimately enhancing the prognosis and wellbeing of those affected by strokes.

This research examines the use of evaluative language in academic writing essays about living in dormitories by 15 EFL undergraduate students at a university in Hanoi. Using Martin & White's Appraisal Framework (2005) and the UAM Corpus Tool, we analysed 15 essays (5725 words). Findings show that students predominantly use Appreciation within the Attitude system and frequently employ quantifiers and intensifiers in Graduation, with only one instance of a Focus item. We also interviewed 7 of the 15 Vietnamese EFL undergraduate students to assess their awareness of the importance of evaluation in writing and to improve their writing capacity.
EFL TERTIARY STUDENTS’ PERCEPTIONS OF LEARNER AUTONOMY IN THE OUT-OF-CLASS LEARNING CONTEXT: SITUATIONS AND DISCUSSIONS
Authors: Ha To Quyen Le , Tan Tin Dang , Thi Thuc Quyen Bui
Published: November 2024

Learner autonomy has been one of the central aims of education because of its significant role in lifelong learning. With the advancement of technology and the abundance of learning resources, students have many opportunities for learner autonomy development outside the classroom. However, the out-of-class learning context is under-explored in the Vietnamese context, and research about fostering learner autonomy in this context is also minimal. The current study aims to explore EFL tertiary students’ learner autonomy in the out-of-class learning context, filling this gap. The results of answers from 709 English majors in different universities in Ho Chi Minh City showed that students had average control in three dimensions of learner autonomy: situational, behavioral, and psychological. Even though students are averagely psychologically ready for independent study, they still lack autonomous learning strategies. Implications are then made for educators to guarantee the possibility of promoting learner autonomy in out-of-class learning.
REALITY OF TRANS-DISCIPLINARY RESEARCH IMPLEMENTATION WITH “RESEARCH TEAM” APPROACH: AN INSIGHT INTO NEGATIVE FACTS AND FIGURES
Authors: Thi Hanh Trinh
Published: November 2024

Complex problems in global development require cooperation among specialists from numerous backgrounds. Consequently, trans-disciplinary research seems to be appreciated due to its exploration of expertise far beyond the the specific boundary of an individual branch. This study seeks to identify negative aspects of the Research Team as an approach to the path of trans-disciplinary research. It was carried out at the National Economics University with 400 participants selected randomly from 20 faculties. Research methods covered questionnaires, semi-structured interviews, and documentary analysis in their institutional studies. It was revealed that despite the values of the Research Team from a theoretical perspective, this approach was not well adapted in reality. The relationship between academics and stakeholders was weak and the practical application of societal solutions was not largely implemented.

Authors: Minh Giang Nguyen , Thi Thuy Linh Bui
Published: November 2024

Experiential learning has been mentioned and directed for implementation in many recent periods of educational reform in our country, especially when implementing the 2018 general education program. However, in reality, not many primary teachers in Ho Chi Minh city apply experiential teaching in Science (2018). Based on the theoretical basis of experiential teaching, the research has proposed four principles when organizing experiential teaching the Substance and Energy topic in Science 4 (2018). At the same time, we build a process for designing lesson plans according to the experiential method including four stages: Determine the goal of organizing teaching according to the experiential method; Determine the content of teaching and learning according to the experiential method; Design experiential learning activities for students; Designing criteria and assessment tools in teaching according to the experiential method of Science 4 (2018). When organizing teaching activities according to the experiential method in teaching Science, follow four steps: Set problems and assign experiential tasks to students; Students perform problem-solving tasks; Organize students to form new concepts on their own; Organize students to experiment in new situations. The research has developed 03 illustrative lesson plans including “Water pollution and protection,” “Sound,” and “Heat transfer and thermal conductors” in the Substance and Energy topic of Science subject 4 (2018) according to the proposed principles and procedures. At the same time, when organizing experimental teaching with lesson plans following the four steps above, the results showed that the test results of students in the experimental class were better than those of students in the control class. Therefore, it can be concluded that the four principles and four steps in the process of designing lesson plans and stages in organizing the teaching of the Substance and Energy topic in Science 4 (2018) according to the experiential method has formed and developed natural science competency components for students according to the requirements to be achieved.

Authors: Ribeiro do Rosário Lúcia Tereza , Monteiro Filocreão Antonio Sérgio
Published: November 2024

A valorização da produção de açaí nos últimos vinte anos proporcionou mudanças significativas no estuário amazônico. O artigo analisa os seus efeitos para famílias agroextrativistas que fazem a extração do fruto, quando este começava a se valorizar no mercado nacional, e num cenário de crescente demanda e valorização nos mercados nacional e internacional e práticas de manejo intensificadas. A área de estudo se concentra no Marajó Ocidental, Estado do Pará e costa do Amapá, nos municípios de Santana e Mazagão. Houve mudanças, sobretudo de curto prazo, refletidas na melhoria da qualidade de vida, aumento da renda familiar, aquisição de bens de consumo, acesso à energia elétrica e meios de transporte. Numa perspectiva futura, tais mudanças dependem cada vez mais do trabalho integral na produção do açaí, e menos em outras atividades produtivas que antes faziam parte da rotina das famílias.

The main problem of using standard optimization methods is the need to change all parameters in same-size steps, regardless of the behavior of the gradient. A more efficient way to optimize a neural network is to set adaptive step sizes for each parameter. Standard methods are based on the square roots of exponential estimates of the moments of the squares of past gradients and do not use the local variation in gradients. The paper presents methods of adaptive non-convex and belief-based optimization with a positive-negative estimate of the moments with the corresponding theoretical guarantees of convergence. These approaches allow the loss function to more accurately converge in the neighborhood of the global minimum in a smaller number of iterations. The utilization of transformed positive-negative moment estimates and an additional parameter that controls the step size allows one to avoid local extremes for achieving higher performance, compared to similar methods. The introduction of the developed algorithms into the learning process of various architectures of multimodal neural network systems for analyzing heterogeneous data has made it possible to increase the accuracy of recognizing pigmented skin lesions by 2.33 – 5.69 percentage points, compared to the original optimization methods. Multimodal neural network systems for analyzing heterogeneous dermatological data, using the proposed optimization algorithms, can be applied as a tool for auxiliary medical diagnostics, which will reduce the consumption of financial and labor resources involved in the medical industry, as well as increase the chance of early detection of pigmentary oncopathologies.

Due to the small number of annotated radar image datasets, the use of optical images for training neural networks designed to detect objects in radar images seems promising. However, optical images have some significant differences from radar images and an experimental investigation of this possibility is required. In this work we investigate the applicability of such an approach and show that in the case of detection of ships good results can be achieved. In addition, it is shown that preliminary filtering of speckle noise can improve the results.

In this work, sharp focusing of vector beams with azimuthal polarization and beams with V-line of polarization uncertainty is simulated numerically using the Richards-Wolf formulas. It is demonstrated that at the sharp focus of these beams the longitudinal component of the electric field vector is zero. Previously, a similar effect was demonstrated only for azimuthally polarized beams. Also, the longitudinal component of the spin angular momentum of these beams is calculated and the possibility of creating sector azimuthally polarized beams using vector waveplates is shown.

We study a new Laguerre - Gaussian (LG) beam, which differs from conventional LG mode beams that preserve the structure of the intensity distribution up to scale. The proposed beam does not retain its structure upon free-space propagation but shows some interesting properties. This beam is Fourier invariant and has extended dark regions in the initial (waist) plane and in the far field. Thus, while maintaining the beam topological charge, the effective diameter of the central dark intensity spot can be increased or decreased by changing the radial index of the Laguerre polynomial. In addition, this beam has the property of autofocusing, that is, at the Rayleigh distance from the waist, the intensity distribution has the form of a light ring (for any value of the radial index) with a minimum diameter and maximum intensity on the ring. This beam can be used to manipulate microparticles without using an additional focusing spherical lens.

In this paper we study the transmission of higher-order modes, including optical vortices (OVs), through a bus fiber evanescently coupled with a vertical array of ring resonators (VAR), which form a vertically stacked multi-ring resonator. It is shown that the OV transmission curves have a characteristic structure that we explain by the manifestation of the band structure of an infinite stack of coupled ring resonators. We demonstrate a fundamental possibility of using VARs as elements of delay lines for fiber-optic communications using orbital angular momentum. It is shown that the VAR is capable of serving as a delay line element for even and odd Laguerre–Gauss modes.

We developed and experimentally implemented an ABCD matrix formalism for describing structural transformations and orbital angular momentum of structured Laguerre-Gaussian beams in an astigmatic optical system containing cylindrical and corrective spherical lenses. It was shown that the matrix formalism not only agrees well with the method of integral astigmatic transformations, but also significantly expands the scope of its application. It was found that a corrective spherical lens is capable of not only separating the vortex and astigmatic components of the orbital angular momentum, but also transforming a structurally unstable astigmatic Laguerre-Gaussian beam after a cylindrical lens into a structurally stable one, provided that the form of fast oscillations and bursts of the orbital angular momentum is preserved.
Meningitis: ¿una enfermedad bajo censura?
Authors: Barata Rita Barradas
Published: November 2024

La traducción al español y reedición de Meningitis: una enfermedad censurada, de autoría de la prestigiosa investigadora y epidemióloga brasileña Rita Barradas Barata es producto de una investigación con compromiso social, que interpela desde la epidemiología a la sociedad ante un evento que afectó la salud de los colectivos sociales de la gran urbe de San Pablo, en la década de 1970, en el marco de la dictadura militar en Brasil (1964 -1984). Este libro destaca la importancia de una mirada social desde la epidemiología descriptiva y la utilidad de esa combinación para problematizar situaciones concretas del proceso salud-enfermedad-atención-cuidado, que los trabajadores de los equipos de salud enfrentan a diario y muy pocas veces se proponen publicar, al imaginar que solo puede ser científico un texto si está acompañado de complejas fórmulas y la utilización de sofisticadas técnicas de análisis. Este texto constituye un buen ejemplo que debe ser tomado como desafío para que esos colectivos de trabajadores cambien esas ideas colonizadoras y se propongan publicar las situaciones que a diario enfrentan y señalan las grandes desigualdades sociales que atraviesan las sociedades que integramos y que permanecen silenciadas. Llevar adelante ese trabajo es también una acción científica, entendida como ciencia contextualizada y no como cientificismo, al decir de Oscar Varsavsky.
Historicizing the Geopolitics of Education and the SDGs: From Western Hegemony to a Multi-polar World?
Authors: Novelli Mario
Published: November 2024

This paper seeks to take a critical and historical look at the rise and fall of the SDGs, with a particular focus on education. At the core of the argument is that the SDGs (2015–2030), their predecessor the Millennium Development Goals (2000–2015), and the Education for All movement (1990 onwards) were the product of a post-Cold War, neoliberal, development agenda whose framing and logic were constructed in a moment of unipolar, US-led, Western hegemony, which today is collapsing around us. Geopolitics and global power are changing in important ways and we need to recognize this, and think through ways to ensure that we can support this in the interests of the marginalized global majority, in education and beyond. “Pax- Americana” needs to be replaced with a “Pax-Pluralis” that can underpin new global models of security, development, and growth that can better address the massive global challenges that we face.

Pod Placement Techniques to Avoid Job Failures Due to Low GPU Memory in a Kubernetes Environment with Shared GPUs
Authors: Kang Jihun , Lee Hwamin , Lee Daewon
Published: November 2024

In a container-based cloud environment, GPUs have the advantage of providing high-performance computation to multiple users, and through GPU sharing, many GPU container users can be accommodated over the number of physical GPUs. This increases resource utilization and minimizes idle time. However, extended resources used to share GPUs in Kubernetes do not partition GPU resources or limit usage and only logically increase the number of GPUs that can be recognized. Therefore, usage limits and equal use of GPU resources cannot be guaranteed among pods sharing GPUs. Additionally, GPU memory generally does not allow for overuse. As a result, if a pod with high GPU memory usage runs a GPU task, it will be unable to limit GPU memory usage and free up available GPU memory. Data must be loaded into the GPU memory to perform the GPU task. However, if the data to be used for computation cannot be loaded into the GPU memory due to insufficient GPU memory, the pod will not be able to start the task and will fail to execute. This paper proposes a pod placement technique to avoid GPU memory shortage when sharing GPUs between pods in the Kubernetes environment. The proposed technique monitors the GPU memory usage and usage frequency of each worker node that makes up the cluster and places the pod on the worker node with the most available GPU memory based on the monitoring information.

Published: November 2024

Parkinson's disease (PD) presents a significant global health challenge, characterized by the progressive degeneration of dopamine-producing neurons in the brain, resulting in both motor and non-motor symptoms that severely impact quality of life. This study addresses the complexities of PD, highlighting the critical need for early diagnosis to slow disease progression. This research addresses the challenges of early diagnosis, such as the use of unreliable diagnostic techniques and limited healthcare resources. It uses the MMU Parkinson Disease Dataset and applies camera-based data collection to analyze gait patterns that can identify a risk of Parkinson's Disease. The study utilizes computer vision and the AlphaPose framework to analyze video data and detect body key points. By employing machine learning algorithms, including Support Vector Machines (SVM) and CatBoost, showing highly effective in identifying temporal dependencies in gait patterns. The algorithms achieved a high accuracy of 83.33% on the MMU dataset. This method enhances the accuracy of PD detection and enables immediate detection and control of the disease. The combination of advanced data analysis methods and medical knowledge offers new possibilities to develop targeted treatments that improve patient outcomes, demonstrating the potential of machine learning in effectively managing and treating Parkinson's disease. To enhance the generalizability of models, future research should collect extensive and diverse datasets covering various backgrounds and different stages of Parkinson's disease and utilize advanced techniques for extracting features to improve the accuracy of gait analysis.

Authors: Ko Dae-Sik , Kim Eun-Jae , Jeong Mi-Ae
Published: November 2024

This study was performed to identify the kinetic and kinematic effects of the lumbar stabilization exercise on obstacle gait(5.2cm,15.2cm) among elderly women at risk of falls. The study subjects were 32 women aged 65 and over with a risk of falls identified by the Tinetti test. They were randomly allocated into 2 groups: the experimental group and the control group, and the lumbar stabilization exercise program was given to the experimental group for 12 weeks. The chi-square test and t-test were used to test homogeneity and compare baseline results of kinetic measurements on obstacle gait between the experimental and control groups. To identify the effects of the lumbar stabilization exercise program among study subjects, repeated measures of analysis of variance (ANOVA) were performed. Regarding kinetic variables, the knee joint angle of the propulsion foot significantly increased when overcoming a 5.2cm obstacle. When overcoming a 15.2cm obstacle, the obstacle overcoming speed and the knee joint angles of the support and propulsion feet significantly increased. However, the shortest vertical distance between the support and propulsion feet was reduced considerably. Our findings suggest that lumbar stabilization exercises could be a promising therapeutic exercise method for fall prevention and management in elderly women at risk of falling, providing reassurance about the effectiveness of our study's findings and the potential benefits for the elderly and other patients requiring trunk stability.
Enhancing Smart Grid Stability through a Hybrid Biometric Pattern Recognition and Long Short-Term Memory Approach
Authors: Uglia Mukhiddinov Muzrob Orif , Kim Yong Min , Oh YeonJae , Lim Chang-Gyoon
Published: November 2024

The stability of power grids is critical in ensuring the consistent and efficient delivery of electricity. However, traditional predictive models often fall short in addressing grid data's intricate and ever-changing nature, making it challenging to maintain grid reliability. This paper introduces a novel hybrid approach that combines Biometric Pattern Recognition (BPR) with Long Short-Term Memory (LSTM) networks to enhance the prediction of smart grid stability. This approach employs BPR techniques to extract essential features from smart grid data by leveraging the pattern recognition capabilities typically used in biometric systems. These techniques are particularly effective in identifying and isolating the most relevant patterns within the complex datasets generated by smart grids. On the other hand, the LSTM-based model is designed to handle the temporal dependencies and nonlinear patterns characteristic of grid data. LSTMs, known for their proficiency in time-series analysis, are well-suited for capturing the sequential nature of grid data, enabling more accurate predictions over time. Integrating BPR and LSTM in this hybrid model addresses several limitations in existing predictive methods. By combining the strengths of both techniques, the model enhances the accuracy of predictions and improves the overall reliability of grid stability assessments. Extensive experiments were conducted using real-world datasets to validate the effectiveness of the proposed hybrid model. The results demonstrate a significant improvement in prediction accuracy, with the BPR-LSTM model achieving a 98.25% increase in accuracy compared to traditional prediction methods. This improvement underscores the potential of the BPR-LSTM hybrid approach to play a pivotal role in advancing the stability and reliability of smart grid systems.

Authors: Fajar Desi Reski , Rostinawati Tina , Hamijoyo Laniyati , Barliana Melisa Intan
Published: November 2024

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by inflammation. The pathogenesis of SLE involves key proteins, including B cell-activating factor (BAFF) and the ubiquitin enzyme A20, both serving as negative regulators of inflammation and contributing to B cell homeostasis. In this review, focused on interventions directed at BAFF and the A20 enzyme, utilizing monoclonal antibodies either independently or in conjunction with conventional therapy for SLE patients.METHODS: A literature search was conducted on the PubMed platform by combining various terms, including "B-cells activating factor", "TNFAIP3 protein (human)", "therapeutics" or "drug therapy", and "lupus erythematosus, systemic" (limited to the last 10 years). From total of 104 articles discovered in thr search, the total number of articles collected after being filtered was 27 articles.RESULTS: Clinical development and evaluation have been conducted regarding the use of appropriate therapy for SLE patients. Selective BAFF inhibitor has been tested in clinical trials as a blocking agent in BAFF receptor (BAFF-R) and signaling nuclear factor-kappaB (NF-κB) by A20 bindings to inhibit the activation of autoreactive B cells. Just like other antimonoclonal therapies, BAFF and the A20 enzyme can be used as therapeutic targets with a single use or combined with the standard therapy in patients with SLE. In addition, the use of BAFF and A20 also shown to have safe side effects in patients with SLE. CONCLUSION: BAFF protein and A20 enzyme present promising therapeutic targets for managing autoimmune diseases like SLE. Therapeutic interventions can be administered individually or in conjunction with standard treatments.  KEYWORDS: systemic lupus erythematosus, therapeutic targets, BAFF, A20

Mets were confirmed following the IDF criteria. NTG was determined based on normal intraocular pressure (IOP) with a mean defect (MD) of the visual field, thinning of the retinal nerve fiber layer (RNFL), and enlargement of cup disc ratio (CDR) by ocular coherence tomography (OCT). Metabolic parameters results of waist circumference (WC), body weight, body height, body mass index (BMI), blood pressures, HbA1c, fasting blood glucose (FBG), lipid profiles; and biomarkers including thiobarbituric acid reactive substance (TBARS) and ferric reducing antioxidant power (FRAP), leptin, adiponectin, high-sensitivity C-reactive protein (hs-CRP), and endothelin-1 (ET-1) were analyzed. Statistical analysis was performed using comparative and correlative tests.RESULTS: From 29 subjects, 19 subjects (65.5%) were included in the NTG group and 10 subjects (34.5%) were included in the non-NTG group. In the NTG group, we found significant correlation between MD with systolic blood pressure (p=0.035); CDR with ET-1 (p=0.049); and CDR with adiponectin (p=0.010). The non-NTG group had a significant correlation between MD with BMI (p=0.043); CDR with LDL (p=0.042); and CDR with TG (p=0.031).CONCLUSION: There are correlation between adiponectin and ET-1 with NTG in MetS patients. Therefore, they might be considered as potential early detectors for NTG in MetS patients.KEYWORDS: normal tension glaucoma, metabolic syndrome, biomarker, endothelin-1, adiponectin

BACKGROUND: The most influential susceptible gene associated with diabetes, transcription factor 7-like 2 (TCF7L2), has been observed in diverse populations. TCF7L2 influences type 2 diabetes risk through glucagon-like peptide 1 (GLP1) production. The presence of risk allele of TCF7L2 leads to the alteration of gene expression in pancreatic beta cells; however, how the mechanism is related with GLP1 remains unclear. This study was conducted to explore the variations of GLP1 increment and insulin secretion between individuals with and without diabetes risk allele of single nucleotide polymorphisms (SNPs) in TCF7L2.METHODS: A cross-sectional analytic study was conducted involving individuals subjects who harbored known variants of SNPs in the TCF7L2: heterozygote or mutant of rs12255372 (GT or TT), rs7903146 (CT or TT), rs10885406 (AG or GG); as well as control subjects with wild type of rs12255372 (GG), rs7903146 (CC), and rs10885406 (AA). Anthropometric parameters, blood glucose, insulin, and GLP1 were measured; and homeostasis model assessment-beta cell (HOMA-%B) index was calculated.RESULTS: The GLP1 increment response was higher in subjects carrying the diabetes risk allele (0.34±0.80 ng/mL) than those with the wild type (-0.04±0.57 ng/mL) (p=0.041). The HOMA-%B was reduced in subjects carrying the diabetes risk allele (71.64±24.72) than those with the wild type (103.23±68.00) (p=0.011). Among individuals carrying the diabetes risk allele, the likelihood of GLP1 increment with high response was twice as high (p=0.007), while the occurrence of low HOMA-%B was 1.47 more frequent (p=0.011).CONCLUSION: TCF7L2 polymorphisms were associated with the GLP1 increment response and reduced HOMA-%B, which might be potentially contributing to GLP1 resistance in patients with diabetes risk factors.KEYWORDS: diabetes risk, TCF7L2, GLP1, HOMA-%B

BACKGROUND: The current biomarker diagnostic modality for acute coronary syndrome (ACS), cardiac troponin, has several limitations. Emerging studies showed that micro-RNA (miR)-133a was released from infarcted heart to circulation, yet the diagnostic value of miR-133a in ACS demonstrated a conflicting result. Therefore, this study was conducted to investigate the potency of plasma miR-133a as a biomarker candidate of ACS.METHODS: This was a case-controlled study, involving ACS and control subjects. The sociodemographic and clinical characteristics were assessed through medical records. A final of 39 ACS and 31 control subjects (consist of healthy and non-ACS subjects) passed the selection procedure by demonstrating a high purity of RNA. miR-133a from ACS and control subjects were detected by quantitative polymerase chain reaction (qPCR). Expression of miR-133a was evaluated for sensitivity and specificity as an ACS biomarker diagnostic using the receiver operating characteristic (ROC) curve.RESULTS: Plasma miR-133a expression was stably found in ACS subjects. The plasma miR-133a level was lower in ACS than in control subjects. miR-133a effectively distinguished ACS subjects from healthy subjects (AUC=0.911) and exhibited high diagnostic performance, with a sensitivity of 87.1% and specificity of 100% at a cut-off value of 44.035. In an extended model including both control subjects (healthy and non-ACS with comorbid conditions), miR-133a maintained diagnostic significance (AUC=0.874), showing sensitivity of 76.9% and specificity of 100% at a cut-off value of 11.69.CONCLUSION: Plasma miR-133a is significantly lower and effectively distinguishes ACS patients from both healthy individuals and non-ACS individuals with comorbid, with a cut-off value of 11.69. Therefore, plasma miR-133a is suggested to be a good candidate for diagnostic biomarkers of ACS.KEYWORDS: circulating miRNA, miRNA-133a, acute coronary syndrome, diagnostic biomarker
A sorte está lançada: um breve ensaio sobre as legiões romanas e sua reconstrução na educação básica
Authors: Felipe Marcio
Published: November 2024

O presente artigo tem como objetivo principal a apresentação de um projeto lúdico, realizado no ano de 2019, sobre as formações de batalha utilizadas pelo exército romano. A tarefa que será apresentada neste texto foi desenvolvida com alunos do 6º ano de uma escola privada na Baixada Fluminense. Utilizando recursos próprios, os alunos construíram escudos semelhantes aqueles que imaginamos que os romanos tenham utilizado e, através da condução do professor, realizaram uma simulação da estratégia militar conhecida como “formação tartaruga”. Além de apresentar a tarefa realizada com os alunos da Educação Básica, buscaremos, nesse trabalho, discutir sobre alguns aspectos importantes para justificar o sucesso militar da legião romana durante a Antiguidade.
Evidência de anglo-saxões nas fontes da Inglaterra anglo-saxônica? Termos e usos no medievo e contemporaneidade
Authors: Albuquerque Isabela , O. S. Medeiros Elton
Published: November 2024

Este artigo tem por objetivo discutir, em função dos recentes debates, as evidências históricas nas fontes documentais medievais referentes ao termo “anglo-saxão” e suas derivações. Com base nos termos utilizados na documentação em inglês antigo e língua latina, abordaremos como os vocábulos identitários foram utilizados para designar os governantes ingleses da ilha e consequentemente a quem eles governavam. Para tanto, será levado em conta, também, os medievalismos e usos do passado a respeito do período chamado de anglo-saxônico, bem como as justificativas por detrás do movimento contemporâneo para abolição do termo.

PARA O BEM DE TODOS: IDENTIDADE CITADINA EM LONDRES NA BAIXA IDADE MÉDIA
Authors: Azevedo de Jesuz Viviane
Published: November 2024

Nosso artigo visa analisar um vetor essencial para a construção da identidade com a cidade medieval, a participação no bem comum. Nascer na Londres medieval não define a identidade do citadino. Observa-se, na verdade, uma série de estratégias que proporcionam a inclusão, ou exclusão, entre os cidadãos de Londres. Por outro lado, mesmo para os citadinos já reconhecidos, é importante criar mecanismos que reforcem o seu pertencimento à cidade, sendo o fortalecimento dos laços sociais no interior da comunidade uma das estratégias fundamentais. A fim de examinar o papel do bem comum nessa construção identitária, voltamos-nos especialmente para os testamentos do Calendar of Wills proved and enrolled in the Court of Husting, assim como registros dos Memorials of London and London Life.
