Conclusão: O estudo evidenciou fatores associados aos agravos por causas externas em idosos e poderá subsidiar formulação de estratégias de enfrentamento a essa problemática.
Por uma virada ontológica no Judiciário brasileiro: um novo papel a ser desempenhado por negros e indígenas
Authors: Bezerra André Augusto Salvador
Published: March 2024

Resumo A histórica desconsideração de saberes não eurocêntricos configura uma das características do colonialismo, fenômeno que persiste no Brasil sob a vigente Constituição, alcançando o Judiciário. O presente artigo examina como tal desconsideração judicial pode obstar a aplicação dos direitos das populações negras e indígenas. Em seguida, propõe uma virada ontológica no Judiciário, para que este amplie a consideração de diversas formas de conhecimento no exercício de suas funções. Metodologicamente, o artigo é assentado em pesquisa bibliográfica interdisciplinar que se soma a exame de duas iniciativas do Sistema de Justiça, realizados a partir de entrevistas semiestruturadas com seus coordenadores: o Polo Indígena de Conciliação na Comunidade de Maturuca em Roraima e o Projeto Vozes dos Quilombos no Piauí. Sob tal método, o artigo procura inovar utilizando o conceito antropológico de virada ontológica para aplicá-lo juridicamente ao Judiciário. Verificou-se, ao final, que as iniciativas examinadas são aptas a revelar possibilidades de escutas judiciais de populações historicamente colonizadas.
As Leis de Anistia nos Órgãos Interamericanos de Direitos Humanos e a Justiça de Transição nos Estados Brasileiro e Argentino
Authors: Bertolin Patrícia Tuma Martins , Kussi Nicoly
Published: March 2024

Resumo Durante o período da guerra fria, os Estados Latino-Americanos, diante da suposta ameaça comunista, viveram sob governos ditatoriais e violência estatal. O Brasil, em 1979, aprovou a Lei de Anistia Política, a qual concedeu anistia ampla tanto aos perpetradores de violência pelo Estado, quanto aos dissidentes do regime. Essa lei continua vigente, sem revisões, em razão do julgamento de uma Arguição de Preceito Fundamental pelo Supremo Tribunal Federal, apesar de posicionamentos contrários do Sistema Interamericano de Direitos Humanos. A Argentina, por sua vez, apesar de ter aprovado, em 1986, a denominada Lei de Ponto Final, que determinava a paralisação do trâmite de ações judiciais que buscavam a condenação dos perpetradores de violência estatal durante a ditadura, reviu o seu posicionamento por meio de um diálogo com a Comissão Internacional de Direitos Humanos. Com a utilização do método comparativo das condições históricas de aprovação e de conteúdo de forma geral, das leis de anistia brasileira e argentina, além da comparação das manifestações do Sistema Interamericano acerca dessas leis, o presente estudo busca mostrar as similaridades e discrepâncias na forma de tratamento interno pelas Cortes Constitucionais Argentina e Brasileira, das declarações do Sistema Interamericano sobre suas leis de anistia, além de avaliar o aspecto da condenação dos responsáveis pelas violências estatais nos dois países, parte indispensável de uma justiça de transição com o uso também do método hipotético-dedutivo e de pesquisa bibliográfica e documental. Por fim, a presente pesquisa explicita a falta de uma boa justiça de transição no Brasil, alicerçada na lei de anistia elaborada ainda durante a ditadura militar, nas condenações do Brasil perante a Corte Interamericana de Direitos Humanos e na confirmação da constitucionalidade da mencionada lei pela Corte Constitucional brasileira, de forma comparada com a forma que a Argentina conduziu a sua justiça de transição, com ruptura e penalização daqueles que perpetraram violências e violações de direitos humanos durante a ditadura, possibilitando a efetividade do direito à verdade e a possibilidade de construção da memória da população.
Forma jurídica e formação social e econômica: Para uma análise das formações sociais dependentes
Authors: Farias João Guilherme A. de
Published: March 2024

Resumo O artigo pretende desenvolver uma reflexão teórica voltada à aproximação entre a leitura pachukaniana da forma jurídica e a teoria marxista da dependência, considerando, de modo subordinado, outras tentativas de caracterização do caráter das relações de produção presentes na formação social brasileira. O fio condutor de nossa análise é a busca pelo aprimoramento do “problema de pesquisa” colocado por Ricardo Prestes Pazello a respeito do caráter dependente da formação social latino-americana e dos efeitos que a dependência exerce sobre a subjetividade jurídica, o que faremos a partir da relação entre forma jurídica e formação social e econômica.

Authors: Batista Nilo
Published: March 2024

Resumo Concebido como a segunda parte de uma aula sobre Inquisição moderna (a primeira está publicada em Capítulos de Política Criminal, Rio, 2022, ed. Revan, pp. 71 ss), o texto contém um estudo dos procedimentos da Inquisição portuguesa, particularmente das disputas relacionadas à (in)suficiência da testemunha única e à ignorância em que os acusados eram mantidos acerca da identidade das testemunhas e das circunstâncias de seus depoimentos, ressaltando-se as funções místicas então atribuídas à confissão. Registradas três aculturações que favoreceram o transplante da mentalidade inquisitorial sobre os povos originários e mais tarde sobre as culturas africanas para cá desterradas, o texto se detém sobre as quatro Visitações que o Santo Ofício empreendeu no Brasil. Por fim, confissões e delações produzidas nessas Visitações fornecem a matéria prima para conhecermos nossas blasfêmias e as atividades de nossos feiticeiros, adivinhos e curandeiros, com a observação de que a perseguição a esses últimos sobrevive nos dias de hoje.

Unmittelbare Anwendbarkeit von völkerrechtlichen Verträgen und Völkergewohnheitsrecht – Deutschland
Authors: Dederer Hans-Georg
Published: March 2024

The practical effectiveness of international treaty and customary law rules depends on their applicability within the domestic legal sphere. The article presents the German constitutional law concepts related to this issue, as theyhave been authoritatively developed and consolidated by the German Federal Constitutional Court. It demonstrates that the principle of “Völkerrechtsfreundlichkeit” (principle of commitment to international law) cannot, on its own terms, determine the conditions upon which public international law is incorporated into the domestic legal sphere. The same applies to the subsequent question as to the conditions under which international treaty or customary law rules are directly applicable. From a German constitutional law perspective, the question of applicability of norms of public international law within the domestic legal sphere is, rather, a question governed by the principle of “offene Staatlichkeit” (principle of openness of the state towards international law). This is a fundamental principle underlying the German constitution which is also important for the final issue of whether and to what extent so-called ‘treaty override’ is constitutionally permissible.

Creating Culture of Thinking in Language Classrooms: An Interpretive Inquiry Into Saudi University EFL Instructors’ Beliefs and Practices
Authors: Abdelhalim Safaa M. , Aldaghri Ashwaq A.
Published: March 2024

Guided by sociocultural theory (SCT) perspectives, this mixed-methods study investigated Saudi university EFL instructors' beliefs and teaching practices regarding the creation of culture of thinking (CoT) in language skills classrooms, and the factors affecting this process. Research data were gathered from 169 EFL university instructors through a self-report questionnaire. Among the participants, 12 instructors participated in a semi-structured interview. Additionally, classroom observations were conducted in seven classrooms. Questionnaire data were analyzed quantitatively using descriptive statistics while interview and classroom observation data were analyzed qualitatively. Instructors’ beliefs were examined in terms of their conceptions of thinking skills, and their perceptions of the importance of creating and sustaining a CoT in EFL classrooms. Their beliefs and reported practices were then compared to their actual classroom practices. Data analysis revealed several key findings. Firstly, there was an obvious incongruence between instructors' stated beliefs, reported practices, and actual classroom teaching practices. Though most instructors were favorable toward the CoT, they did not apply it to their classrooms. Secondly, several factors were identified to have mediated instructors' beliefs and practices pertaining to the CoT. These factors were related to cultural values (e.g., individual thinking, obedience, and respect for adults) as well as institutional and classroom contexts (e.g., workload, examination system, students’ thinking habits, and language proficiency). Finally, instructors lacked the strategies necessary to effectively implement CoT. Based on these findings, pedagogical implications and future research studies are proposed.
Intertextualizing Interactive Texts for Teaching Synonyms Using Digital Platforms: An Experimental Study Engaging the First-Year Undergraduate Students
Authors: Kamalesh F. Joseph Desouza , C Suganthan
Published: March 2024

With Content and Language Integrated Learning (CLIL) gaining greater attention in English Language Teaching, more emphasis has been given to teaching content-based vocabulary to students. However sufficient attention has not been given to widening the students' knowledge to make them learn synonyms (equivalent words). In this research, we explore the possibilities of teaching synonyms to First Year College students using Interactive Texts. This is done through the use of Mobiles and other classroom gadgets available. Interactive learning methods utilizing Interactive Texts actively engage the learner’s intellect and emotions by strengthening the connection to the content. Beyond the use of traditional textbooks and methods, this methodology includes a variety of tasks that promote engagement with printed materials, such as Directed Activities Related to Texts (DARTs), as well as mobile-based activities that improve students' reading and comprehension skills. This activity-based instruction introduces students to a variety of vocabulary. It enhances their word power by not only teaching them synonyms but also the application of the same in their real-life situations in the most appropriate way.

Authors: Nurrahma Arinal Haq Izzawati , Putri Hana Haruna , Syahadat Ray March
Published: March 2024

Data collection was gathered from PubMed, Google Scholar, Semantic Scholar, and Crossref in Harzing”s Publish or Perish software. The keyword used in this study was "Flooding Stress" with the publication year of the 1962-2021 articles. Results showed that PubMed retrieves more relevant manuscripts from journal sources than other databases. The search method by whole years was the most effective and efficient if the total manuscripts are less than 1000. Flooding stress-related manuscripts were published continuously from 1994 to 2021 with Annals of Botany as the most productive journal. A combination of “Flooding Stress” with related keywords, e.g., submergence stress, anaerobic stress, and oxidative stress, improves the relevancy of the manuscript results. VOSviewer keyword analysis found that there were 5 clusters discussing oxidative stress, tolerant mechanism, physiological mechanism, flood occurrence, and molecular mechanism. Based on the density visualizations, the anaerobic metabolism, mRNA expression level, SOD, fv/fm, leaf gas exchange, ABA biosynthesis, and halophyte lead to potential topics of flooding stress research to be studied in the future.

Published: March 2024

The purpose of this study is to focus on producing a protection system design for the electrical loads of administration buildings from over and under voltage. An on-site voltage reading has been initiated and continued for several days to determine whether voltage variation is occurring in the location. The building’s load schedule has served as a point of reference in calculating the appropriate size of wire and Molded Case Circuit Breaker ampere rating. For the proponents to understand the design standards, the Philippine Electrical Code is used as a reference. Consequently. The design that has been made and proposed is for controlling over and under voltages. The power supply at the Administration building can be transferred over to the other power supply coming from a generator set. The voltage readings in the Admin Office MDP range from 218.55 to 231.03 V. The other one on the General Office MDP is from 219 to 230.48 V, showing that no over-voltage and under-voltage is happening in the building and normal working voltages are delivered on the electrical loads. Thus, the electrical loads in the building are safe from voltage variations.

Published: March 2024

Background. Currently, for patients with localized PC, intact erectile function, and low risk of extracapsular extension radical prostatectomy (RP) with nerve-sparing (NS) technique is indicated. The proven method of intraoperative control for the presence of positive surgical margin is the study of fresh frozen sections.

Aim. To evaluate the method of intraoperative histological examination (cito-histology) in NS RP.

Materials and methods. A prospective clinical study was conducted to examine fresh frozen sections in laparoscopic NS RP. Between February of 2021 and May of 2022, 90 patients diagnosed with prostate cancer underwent laparoscopic NS RP performed by the same surgeon. The patients were divided into 2 groups: group A (n = 40) included patients who underwent laparoscopic NS RP and intraoperative histology; group B (control group) (n = 50) included patients who underwent standard laparoscopic NS RP. Rapid histological and final histological examinations of all removed samples were carried out at the City Clinical Hospital No. 1 named after N.I. Pirogov by one pathologist. The presence of tumor tissue in a stained resection margin was considered positive surgical margin.

Results. Oncological processes in macrosamples obtained by intraoperative histology were observed in 32 (80 %) patients, of which primary positive surgical margin was found in 9 (22.5 %) patients. Conversion of (cito) positive surgical margin status into final negative surgical margin was observed in 4 (10 %) patients. Conversion of the surgical margin status of (cito) negative to positive was observed in 1 (2.5 %) patient due to the targeted examination of the area of interest, and not the entire surface of the prostate. Overall 2-year survival in groups A and B was 100 % and 96 %, respectively; cancer-specific 2-year survival was 100 % and 100 %, respectively. Depending on the pathological group, recurrence-free 2-year survival was: group A (pT2) – 90 %; group B (pT2) – 92 %, group A (pT3) – 91.3 %; group B (pT3) – 77.3 %.

Conclusion. The proposed method of intraoperative histological examination allows to determine the presence and location of positive surgical margin, which indicates to the surgeon the necessity of additional tissue removal in the neurovascular bundle area, reduces the technical and economic burden on pathology department compared to other methods of rapid histological examination, and reduces contraindications to performing the NS technique in RP especially in the intermediate-risk group.

Authors: Dubrovin V. N.
Published: March 2024

Radical cystectomy remains the “golden standard” for treatment of patients with invasive bladder cancer. The operation is a technically complex surgical intervention after which there are various complications, including gastrointestinal complications such as intestinal obstruction, peritoneal adhesive disease and others. The use of extraperitoneal access for radical cystectomy with an extraperitoneal location of the artificial bladder in carefully selected patients reduces the number of abdominal postoperative complications and improves results in the immediate postoperative period. A literature review is presented which outlines the results of using extraperitoneal approach in comparison with other options for surgical approaches when performing radical cystectomy with intestinal bladder plastic surgery. It is noted that extraperitoneal access during this operation was previously used by Russian urologists.

Published: March 2024

In recent years, the term 'smartness' has entered widespread use in research and daily life. It has emerged with various applications of the Internet of Things, such as smart homes and smart factories. However, rapid technological development and careless use of the term mean that, in information systems (IS) research, a common understanding of smartness has not yet been established. While it is recognized that smartness encompasses more than the use of impressive information technology applications, a unified conceptualization of how smartness is manifested in IS research is lacking. To this end, we conducted a structured literature review applying techniques from Grounded Theory. We found that smartness occurs through actions, in which smart things and individuals interact, process information, and make data-based decisions that are perceived as smart. Building on these findings, we propose the concept of a 'smart action' and derive a general definition of smartness. Our findings augment knowledge about how smartness is formed, offering a new perspective on smartness. The concept of a smart action unifies and increases understanding of 'smartness' in IS research. It supports further research by providing a concept for describing, analyzing, and designing smart actions, smart devices, and smart services.

Published: March 2024

This study aims to comprehensively explore the emotional, personal, and metacognitive predictors of the psychological well-being of teachers. The article presents the results of identifying personality traits, features of the emotional sphere and regulation of emotions, as well as features of metacognition that can influence well-being of teachers in modern conditions. To measure these characteristics, the following methods were used: a short portrait questionnaire of the Big Five; methodology “Differential Scale of Emotions”; methodology for diagnosing the subjective well-being of the individual; Metacognitive Awareness Inventory; test “Differential Type of Reflection”; Cognitive Emotion Regulation Questionnaire and the author's self-assessment questionnaire of metacognitive behavior “Metacognitive Skills in the Structure of Educational and Professional Activities”. Study sample: 106 people aged 20 to 75 years (average age 45,85) – teachers, lecturers, heads of departments of higher educational institutions and colleges. It is shown that the higher levels of metacognitive involvement correspond to the higher levels of subjective well-being. A high index of positive emotions, higher levels of trait conscientiousness and conscious use of metacognitive skills, positive revision and acceptance strategies, and lower acute negative emotions index also have a positive effect. The results described can be helpful in preventative and therapeutic work with the symptoms of professional burnout of teachers.

Published: March 2024

Despite ample evidence of the positive impact of education on people's lives, the duration of this effect have not been sufficiently explored. The purpose of the present study is to identify how the level of education affects various aspects of life satisfaction in retirement. In order to realize the goal, a structural model of the influence of education on life satisfaction in retirement was developed and verified on a sample of pensioners from the industrial region of Russia (n=291), highlighting the role of cognitive phenomena (psychological age and basic beliefs). The results of the analysis of the empirical model confirm the main hypothesis: a higher level of education increases life satisfaction in retirement, both directly and indirectly – through cognitive structures. It affects all measured indicators of satisfaction: psychological well-being, income satisfaction, perception and attitude towards retirement period of life, subjective assessment of health. The results of the study expand the understanding of the role of education as a factor of late socialization, and also serve as a basis for recommendations on the content of the learning process.

Authors: Chudinova E.V. , Zaitseva V.Y. , Minkin D.I.
Published: March 2024

The task of the work is to present initiative and independent educational modeling as the highest possible achievement of high school students (15 -17 years old). The application of the "case study" within the framework of a multi-year genetic-modeling experiment made it possible to describe the precedents of educational modeling in high school, demonstrating the initiative and independence of students in modeling. An analysis was carried out of video recordings of 14 lessons on setting and solving one educational problem, the results of a focus group with 5 teachers and written work of 20 eleventh grade students. Due to prior learning based on the principles of learning activities, students of this age are able to invent and analyze modeling tools necessary to capture implicit subject relations, as well as to transform the model by holding the problem for the time necessary to solve it. In this case, the training model acquires the features of an exploratory model. It is shown that the model is not only a means of fixing subject relations for the classroom community, but also a way of expressing their understanding, i.e. a means of communication.

Authors: Gordeeva T.O. , Sychev O.A.
Published: March 2024

Academic achievements of teenage students are an important indicator of their further success and adaptation to life in adult society. The material of the study was the data collected for the international project PISA 2018 on a representative sample of Russian teenagers (N=7608). The article presents the results of studying the role of educational and motivational factors (controlling for gender and family environment) of academic achievements of Russian teenagers based on the material of PISA 2018 on reading literacy. We confirmed that regarding the environmental (family and teacher) factors in the academic achievements of schoolchildren, the role of SES as an important predictor of schoolchildren's academic achievements, the role of teacher support for active involvement in reading is significantly positive factor, and Teacher-directed instruction is negative factor. The study confirmed an important contribution of motivational variables to reading literacy, reading engagement was proved to be a positive predictor, and fixed mindset about intelligence was proved to be a negative predictor of reading literacy competence. The discussion shows that the data obtained generally corresponds to international data on predictors of academic achievement among schoolchildren based on the PISA 2018. The results obtained can be used in the context of teacher training and for improving the quality of education in Russian schools.

Published: March 2024

The article reveals the degree of effectiveness of segregated and inclusive forms of psychological and pedagogical support for students with special educational needs. In the psychological experiment took part 68 students with disabilities, its purpose was to identify the dynamics of the psychological well-being of the students depending on the inclusive or segregated forms of psychological trainings they took part in. As a result of the study, carried out with the help of the Scale of psychological well-being K. Riffe (adaptation of T.D. Shevelenkova, T.P. Fesenko), questionnaire Life Style Index (Plutchik, Kellerman, & Conte, 1979) and the methodology of SUN (V.A. Doskin, N.A. Lavrentieva, V.B. Sharay), we found out the differences between the groups of students according to their mood (t=7.55; p<0.001), well-being (t=4.89; p<0.001), activity (t=4.78; p<0.001), psychological well-being (t=4.65; p<0.001), tension of psychological defenses (t=2.27; p<0.05). These factors indicate the negative dynamics of psychological well-being of students with disabilities who studied in segregated groups with no conditionally healthy students. Based on the results of the psychological experiment, we made a conclusion, that the segregation of students with disabilities from other students is inexpedient, even if the purpose was providing them with psychological assistance in higher education.

Published: February 2024

A população mundial tem apresentado crescimento significativo nos últimos anos, por isso, é necessário o aumento na produção de alimento para abastecimento da mesma. O emprego de biotecnologias reprodutivas objetivando multiplicação de animais geneticamente superiores é essencial para otimizar a produção animal, uma vez que se tem animais mais produtivos. Contudo, a estacionalidade das chuvas em países de clima tropical como o Brasil pode comprometer o sucesso dessas biotecnologias. Assim, o objetivo com este trabalho foi avaliar os resultados da produção in vitro de embriões durante as estações chuvosa (meses de Janeiro a Março) e seca (meses de Julho a Setembro). Para tanto, fêmeas bovinas da raça Gir (n=15) foram submetidas a aspiração folicular durante ambas estações e avaliados a recuperação ovocitária, a produção embrionária e taxa de concepção, além do desenvolvimento embrionário para cada estação. Maior média (4,5 ± 0,5 vs. 3,08 ± 0,3) e taxa de embrião (51,02 vs. 38,64) foram observados na estação chuvosa em relação a seca (p<0,05). Contudo, a recuperação ovocitária e taxa de concepção não foram afetados pela estação do ano. Conclui-se que a estação do ano compromete diretamente os resultados da produção in vitro de embriões, sendo essencial buscar alternativas para minimizar este efeito.

Abstract With the growing world population, food production must be increased. Thus, reproductive biotechnologies must be used to produce genetically superior animals and optimize animal production. However, the success of such biotechnologies can be compromised by seasonality. This study was performed to evaluate in vitro embryo production (IVEP) in wet (January–March) and dry (July–September) seasons. Gir females (n = 15) were subjected to follicular aspiration in both seasons. Their oocyte recovery, embryo production, pregnancy, and embryo development in each season were evaluated. The mean (4.5 ± 0.5 vs. 3.08 ± 0.3) and embryo rate (51.02 vs. 38.64) in the wet season were higher than those in the dry season (p < 0.05). However, oocyte recovery and pregnancy rate were unaffected by the season. Therefore, seasonality directly compromises IVEP results.

This device may be more adaptable to a specific bacterium than vancomycin powder as it allows the mixtures of specific bactericidal antibiotics to treat bacterium with specific sensitivities. Design: A multicenter, non-randomized, uncontrolled prospective cohort study. Setting: Five level 1 trauma centers. Participants: Thirty adults with an acute closed tibia plateau fracture, OTA 41B and 41C fractures, requiring operative fixation. Intervention: After fracture fixation, the subchondral bone void was filled with the study device. Main Outcome Measures: Local wound reaction to the device was assessed and resorption of the calcium sulfate was measured on serial x-rays. Follow-up assessments occurred at six weeks, three months, six months and one year, with a CT scan performed at six months to determine resorption of the device. Results: Thirteen male and 17 female participants were recruited with a mean age of 53.3 ± 12.8 years. The median age was 55 years with a range of 29 to 78 years of age. Two participants reported serous drainage: one resolved without treatment, the other was diagnosed as a deep infection and required plate removal and oral antibiotics. There were no local or systemic allergic reactions. Resorption of the material averaged 70% by three months, 87% at six months, and 100% at one year. Conclusions: This device performed as anticipated and completely resorbed without any unexpected adverse events. It allowed for personalizing antibiotic choice with better reported elutional characteristics than vancomycin powder over two weeks and six weeks. Surgical site drainage was low, and 97% union rate was achieved. This is a safe surgical augment for local release of a chosen antibiotic into a contained subchondral defect in a periarticular fracture.

Infertility is one of the major health problems of reproductive age couples. The suggestion that oestrogen beta receptor polymorphism has unfavorable effects on the male fertility is contentious. This review study aimed to identify the impact of estrogen beta receptor polymorphism on male infertility. The comprehensive literature review focused on the role of estrogen beta receptor (ERβ) in the testis, its effects on sperm motility, longevity, and fertilizing capacity, as well as the relationship between ERβ mutation and male infertility. The review highlighted the critical role of ERβ in sperm function, emphasizing its strong expression in the testis and its significance for sperm motility and fertilizing capacity. The absence of ERβ was found to diminish epididymal sperm content, sperm motility, and fertility, thereby contributing to male infertility. Additionally, the review discussed the influence of environmental, physiological, and genetic factors on male factor infertility and emphasized the need for further molecular studies to determine the implications of ERβ mutation in a multifactorial manner. The literature cited in the review provided insights into the prevalence of male infertility worldwide, with a focus on the African region, where male factor infertility was found to account for a significant percentage of infertility cases. Genetic evaluations and lifestyle changes, including the inclusion of antioxidant vitamins and minerals in treatment regimens to prevent oxidative DNA damage linked to estrogen-induced effects on male reproduction, were recommended. Furthermore, healthy lifestyle choices and the avoidance of tobacco smoking, marijuana, and alcohol use may play central role in preserving male fertility.
Clinical Evaluation of Dyspnoea in Obstructive Lung Disease – Progressing from Psychometrics to Physiology
Authors: Ong Kian
Published: March 2024

Dyspnoea is a common symptom that afflicts persons with myriad medical conditions. Among sufferers of lung disorders such as chronic obstructive pulmonary disease, dyspnoea, together with effort intolerance, are the major complaints. Dyspnoea is a marker of disease severity and adverse prognosis of chronic obstructive pulmonary disease, and the need for symptom alleviation in improving health status is ever-present, but the quantification of this symptom is challenging in clinical practice, and is mostly limited to the use of questionnaires and self-reports currently. Numerous psychometric tools have been developed to measure the severity of dyspnoea clinically, but their utility is vitiated by the complexity and multidimensional nature of the symptom. The lack of a universally accepted and accurate measurement tool is likely to hinder future progress in developing novel treatments for relieving dyspnoea. Physiological measurements have been used to complement or supplant psychometric evaluation of dyspnoea but simple stationary lung function tests do not correlate sufficiently well with dyspnoea severity in patients with chronic obstructive pulmonary disease, while complex exercise testing is impractical or limited to specialized research labs. In recent years, the use of non-invasive surface electromyography of the diaphragm and/or accessory muscles of respiration is gaining attention as a promising physiological assessment of dyspnoea with potential for widespread clinical applications. Although substantial technological gaps still exist between bench and bedside, the current interest, as evidenced by the number of med-tech collaborations in surface respiratory electromyography, appears to be well justified. This review aims to summarize the past and present methodologies as well as future developments in evaluating and quantifying dyspnoea, especially in patients with chronic obstructive pulmonary disease.
Amyloid Protein in AL-Amyloidosis. Natural History and Potential for Regression
Authors: Lefkowitz Charles
Published: March 2024

Amyloid light chain amyloidosis is the most commonly seen form of systemic amyloidosis and is characterized by the accumulation of circulating monoclonal immunoglobulin light chain precursors arising from an abnormal clone of plasma cells. These light chain precursors demonstrate a propensity for misfolding, aggregation and deposition as highly stable fibrillar cross-linked beta sheets in various tissues and organs in a manner characteristic of other forms of systemic amyloidosis. There have been great advances in the treatment of the underlying plasma cell dyscrasia with improved long-term survival but the persistence of extracellular amyloid deposits in the tissues of vital organs, particularly the heart and kidney remains a significant cause of morbidity and mortality even in those patients in whom a hematological complete response has been achieved. This review focuses on the importance of early diagnosis and treatment on limiting the extent of amyloid protein accumulation and organ dysfunction and the current state of knowledge on the potential for resorption and clearance of these amyloid deposits in patients with amyloid light chain amyloidosis. The status of current novel anti-fibrillar agents is reviewed and future strategies for effectively intervening to improve organ function and survival these individuals is discussed.

Frequency dynamics is one of the important aspects of power system stability. From the frequency dynamics, the operator could plan how is the reliability of the electricity. The frequency can be maintained by controlling the balance between load demand and generation. To maintain the balance of the generation, the governor is playing an important role to increase the speed of the turbine and enhance the generating capacity of the generator (ramp-up). However, as the speed of the governor is slower than the increasing load demand, in the sub-transient area, the frequency may experience higher overshoot. Hence, it is important to add additional devices such as battery energy storage systems to enhance the frequency dynamics response in the sub-transient area. One of the important parts of storage is the controller. The controller must make sure the storage charges and discharge energy are in the sub-transient area. Hence PID controller can be the solution to make the storage operate optimally This paper proposed a novel PID controller on battery energy storage systems (BESS) to enhance the dynamics performance of frequencies. The five-area power system is used as the test system to investigate the efficacy of the proposed novel idea. Time domain simulation is investigated to see the improvement of the frequency dynamics response. From the simulation results, it is found that adding a PID controller on BESS could enhance the BESS response and result in frequency dynamics response improvement.

Published: February 2024

Patients with spinal cord injury (SCI), stroke, and coronavirus patients must undergo a rehabilitation process involving programmed exercises to regain their ability to perform activities of daily living (ADL). This study focuses on the rehabilitation of the foot-ankle joint to restore ADL through the design and implementation of a rehabilitation exoskeleton with three degrees of freedom (abduction/adduction, inversion/eversion, and plantarflexion/dorsiflexion movements). increase the patients cause worker fatigue, emotional exhaustion, a lack of motivation, and feelings of frustration, all contributing to a decrease in work efficacy and productivity. The robotic exoskeleton was developed to overcome this limitation and support the medical rehabilitation section.   The main goal of this study is to develop a portable exoskeleton that is comfortable, lightweight, and has a range of motion (ROM) compatible with human anatomy to ensure that movements outside of this range are minimized, the anthropometric parameters of a typical human lower foot have been considered. In addition, it's a home-based rehabilitation device which means the exoskeleton can be used in any environment due to its lightweight and small size to accelerate the rehabilitation process and increase patient comfort.  The proposed autonomous exoskeleton structure is designed in Solid Works and constructed with polylactic acid (PLA) plastic, the reason PLA was chosen is its lightweight, available, stiff material, and low cost, using 3D printing technology the exoskeleton was manufacturing. Electromyography (EMG) and angle data were extracted using EMG MyoWare and gyroscope sensors, respectively, to control the exoskeleton. It was evaluated on its own then with 2 normal subjects and 17 patients with stroke, spinal cord injury (SCI), and coronavirus. The limitation that has been faced was that the sessions were limited due to the limited time provided for the study. According to the improvement rate, the exoskeleton has a significant impact on regaining muscle activity and improving the range of motion of foot-ankle joints for the three types of patients. The rate of improvement was 300%, 94%, and 133.3% for coronavirus, SCI, and stoke respectively. These results demonstrate that this exoskeleton can be utilized for physiotherapy exercises.
