“O nome era de homem, mas era um corpo de mulher”: a população transexual na Estratégia Saúde da Família
Authors: Spadim Bárbara Cristina de Léo , Mendonça Carolina Siqueira , Cyrino Eliana Goldfarb
Published: June 2024

Apesar da criação de políticas que buscam equidade para as pessoas transexuais, reconhece-se uma realidade alarmante evidenciada pela elevada vulnerabilidade. Ao buscar assistência à saúde, essas pessoas vivenciam experiências que produzem barreiras a esse acesso. Objetiva-se analisar os desafios no cuidado à saúde dessa população nos serviços de Estratégia Saúde da Família, em um município de São Paulo, caracterizando as representações dos profissionais, ofertas de cuidado e capacitações. Trata-se de uma pesquisa qualitativa e exploratória, realizada a partir de entrevistas semiestruturadas. A investigação é referenciada pela análise de conteúdo segundo Minayo e por estatística descritiva. Os núcleos elaborados foram: “A demanda existe”, “O vazio formativo” e “Ecos da violência”. Os relatos apontam para estigmas, falta de políticas públicas, preconceitos e violências associadas às pessoas transexuais.
“Eu preferia estar doente!”: o cuidado a contrapelo. Um breve ensaio sobre o que a pandemia de Covid-19 pode revelar acerca do ofício da antropóloga
Authors: Pimenta Denise
Published: June 2024

O presente ensaio se propõe a pensar, a partir de uma inspiração benjaminiana, o cuidado a contrapelo, buscando desnudá-lo. A autora do texto cruza sua experiência de cuidadora durante a pandemia de Covid-19 com as narrativas de suas interlocutoras na Serra Leoa (África do Oeste) durante a epidemia do ebola (2014-2016). A interseção dessas realidades – antropóloga-cuidadora e mulheres serra-leoneses cuidadoras – acaba levando a pesquisadora a pensar o próprio ofício da Antropologia, considerando questões de nomeação, gênero, raça, subalternidade, lugar de fala e o engenhoso espaço da relacionalidade.

Authors: Souza Raniel Martinha de , Luna Willian Fernandes , Teixeira Iraí Maria de Campos
Published: June 2024

El artículo describe experiencias de indígenas universitarios que vivieron en una residencia estudiantil durante el período de distanciamiento social ampliado en el primer semestre de la pandemia de Covid-19. Se trata de una investigación cualitativa con utilización de diario de campo, estudio documental y entrevistas. Se realizó un análisis temático de contenido, bajo la óptica de los conceptos de situación-límite, inéditos-viables y resiliencia. Se identificaron dos categorías: sufrimiento en el contexto del distanciamiento social y estrategias de superación de dificultades. Vivieron incertidumbres y límites causados por la pandemia, miedos por estar distantes y por enfermarse. Como enfrentamientos, surgieron adaptaciones en la enseñanza, investigación y extensión, estrategias individuales más allá de las actividades académicas y buscaron construcciones colectivas posibles en el sentido de la resiliencia y de la desconstrucción de visiones estereotipadas en el ambiente académico.
APORTES TEÓRICOS DE EPISTEMOLOGIAS AFRICANAS
Authors: Silva Mariana Martha de Cerqueira
Published: June 2024

Este estudo é um ensaio teórico sobre epistemologias africanas. A Resolução N.º 018/2002 do Conselho Federal de Psicologia defende a inclusão desse referencial teórico nas disciplinas dos cursos de formação em Psicologia. Em vista de aprofundar o debate, este ensaio remete a matrizes teórico-conceituais de autoria africana para apreender realidades advogadas por essa raiz epistemológica. Para isso, articulam-se informações conceituais pautadas em estudos de intelectuais africanos/os contemporâneos/os sobre experiências, análises e interpretações de África, a partir dela mesma. Os poucos registros de estudos de Psicologia que circulam no Brasil sobre pensamentos e experiências de povos africanos, evidenciam a pertinência do aprofundamento desse aporte teórico. Tais racionalizações expandem construções teóricas e destacam o apelo à geopolítica do conhecimento como um fator que opera sobre a produção do conhecimento, (re)configurando e pluridimensionando lógicas eruditas de pensamento, como as epistemologias africanas.

Angiotensin II–Type-1a Receptor and Renal K+ Wasting during Overnight Low-Na+ Intake
Authors: Duan Xin-Peng , Zheng Jun-Ya , Xiao Yu , Zhang Cheng-Biao , Lin Dao-Hong , Wang Wen-Hui
Published: June 2024

Key Points

Angiotensin II–type-1a-receptor in the distal convoluted tubule (DCT) plays a role in regulating sodium transport in the DCT.

Angiotensin II–type-1a-receptor in the DCT plays a role in maintaining potassium homeostasis during sodium restriction.

Background

Chronic angiotensin II perfusion stimulates Kir4.1/Kir5.1 of the distal convoluted tubule (DCT) via angiotensin II–type-1a-receptor (AT1aR), and low‐sodium intake also stimulates Kir4.1/Kir5.1. However, the role of AT1aR in mediating the effect of low salt on Kir4.1/Kir5.1 is not explored.

Methods

We used the patch-clamp technique to examine Kir4.1/Kir5.1 activity of the DCT, employed immunoblotting to examine Na-Cl cotransporter (NCC) expression/activity, and used the in vivo perfusion technique to measure renal Na+ and renal K+ excretion in control, kidney tubule–specific–AT1aR-knockout mice (Ks-AT1aR-KO) and DCT-specific–AT1aR-knockout mice (DCT-AT1aR-KO).

Results

Angiotensin II acutely stimulated the 40-pS-K+ channel (Kir4.1/Kir5.1-heterotetramer) and increased whole-cell Kir4.1/Kir5.1-mediated K+ currents and the negativity of DCT membrane potential only in late DCT2 but not in early DCT. Acute angiotensin II increased thiazide-induced renal Na+ excretion (ENa). The effect of angiotensin II on Kir4.1/Kir5.1 and hydrochlorothiazide-induced ENa was absent in Ks-AT1aR-KO mice. Overnight low-salt intake stimulated the expression of Agtr1a mRNA in DCT, increased whole-cell Kir4.1/Kir5.1-mediated K+ currents in late DCT, hyperpolarized late DCT membrane, augmented the expression of phosphor-Na-Cl-cotransporter, and enhanced thiazide-induced renal-ENa in the control mice. However, the effect of overnight low-salt intake on Kir4.1/Kir5.1 activity, DCT membrane potential, and NCC activity/expression was abolished in DCT-AT1aR-KO or Ks-AT1aR-KO mice. Overnight low-salt intake had no effect on baseline renal K+ excretion (EK) and plasma K+ concentrations in the control mice, but it increased baseline renal-EK and decreased plasma K+ concentrations in DCT-AT1aR-KO or in Ks-AT1aR-KO mice.

Conclusions

Acute angiotensin II or overnight low-salt intake stimulated Kir4.1/Kir5.1 in late DCT, and AT1aR was responsible for acute angiotensin II or overnight low-salt intake–induced stimulation of Kir4.1/Kir5.1 and NCC. AT1aR of the DCT plays a role in maintaining adequate baseline renal-EK and plasma K+ concentrations during overnight low-salt intake.
Replication in the Humanities in Action: Reflections on a Direct and a Conceptual Replication in the History of Science and Religion
Authors: Peels Rik , Pear Rachel , van Eyghen Hans , van den Brink Gijsbert
Published: June 2024

In this article, we reflect on our direct and conceptual replications, the results of which were presented in the previous two articles in this thematic section. While those articles are primarily meant to report the findings of the replications, we here seek to explore what the process and its results mean for replication in historiography. First, we discuss what we consider the main challenges we encountered in both replication studies and how we dealt with them. Then, we present what we consider the eight main lessons learned from both replication studies. Subsequently, we return to various objections and hesitations that have been raised regarding replication in the humanities in general and historiography in particular. We explore whether our findings and reflections shed new light on how those objections and hesitations should be dealt with. Finally, we draw some conclusions.
Crisis, Confidence, and the Limits of Replication
Authors: Brown Jeremy
Published: June 2024

There have been calls for a program of replication in the humanities. Although usually thought of as confined to the hard sciences, replication may, under the correct conditions, be a useful tool for historians who propose an explanation of why a set of events occurred. But the program of replication in the humanities is challenged when we consider degrees of freedom, i.e., the number of independent parameters that function within a system. Evidence from the sciences has revealed that experimental variables once thought of as unimportant might in fact be critical. Change just one of them and the experimental result changes in ways that were at first unimaginable. How then, are we to know if the degrees of freedom offered as part of a historical explanation are indeed satisfactory? There are constraints to what may be replicated, but this is the case for the sciences no less than for the humanities.

Circulating soluble suppression of tumorigenicity-2 and the recurrence of atrial fibrillation after catheter ablation: A meta-analysis
Authors: Shi Yanyu , Zhang Zepeng , Zhang Tianyang , Zhang Linlin , An Shan , Chen Ying
Published: June 2024

Soluble suppression of tumorigenicity-2 (sST-2), a marker of myocardial fibrosis and remodeling, has been related to the development of atrial fibrillation (AF). The aim of this meta-analysis was to evaluate the relationship between baseline serum sST-2 levels and the risk of AF recurrence after ablation. Relevant observational studies were retrieved from PubMed, Web of Science, Embase, Wanfang and China National Knowledge Infrastructure (CNKI). A random-effects model was used to combine the data, accounting for between-study heterogeneity. Fourteen prospective cohorts were included. Pooled results showed higher sST-2 levels before ablation in patients with AF recurrence compared to those without AF recurrence (standardized mean difference = 1.15, 95% confidence interval [CI] = 0.67 to 1.63, P < 0.001; I2 = 92%). Meta-regression analysis suggested that the proportion of patients with paroxysmal AF (PaAF) was positively related to the difference in serum sST-2 levels between patients with and without AF recurrence (coefficient = 0.033, P < 0.001). Subgroup analysis showed a more remarkable difference in serum sST-2 levels between patients with and without AF recurrence in studies where PaAF was ≥ 60% compared to those where it was < 60% (P = 0.007). Further analyses showed that high sST-2 levels before ablation were associated with an increased risk of AF recurrence (odds ratio [OR] per 1 ng/mL increment of sST-2 =1.05, OR for high versus low sST-2 = 1.73, both P values < 0.05). In conclusion, high sST-2 baseline levels may be associated with an increased risk of AF recurrence after catheter ablation.
Administrative Justice
Authors: Panova Inna , Zaraiskiy Aleksander
Published: June 2024

Based on an analysis of the current state of legislation and judicial practice and also of certain specific development trends, this article considers the issues relevant to administrative and judicial reforms, identifies a number of terms important for understanding the matter in question, and highlights various problems in trying administrative cases in courts as well as in pre-trial (extrajudicial) proceedings. The new Code of Administrative Judicial Procedure of the Russian Federation is examined closely for its consistency with other procedural laws. The article also points out the problem in jurisdiction over administrative cases that may arise among the several panels of the Supreme Court of the Russian Federation, which may arrive at different outcomes in similar disputes. The general jurisdictional approach used by courts to consider administrative offenses related to entrepreneurial activities is critically assessed. The disadvantages of rulemaking in administrative cases exercised by the economic panel of the RF Supreme Court are also outlined. After analyzing the problem of pre-trial compensation for damages caused by illegal actions of administrative bodies, a number of statutory innovations for establishing pretrial damages and tightening the procedures and measures of such liability for administrative entities are suggested. It is advisable to establish a special centralized administrative body for out-of-court settlement of administrative cases within Russia’s executive system. This would ensure the effectiveness of the institution for handling a general administrative complaint and provide administrative protection of citizens’ rights. Such a body would be able both to depoliticize and de-bureaucratize administrative authorities, and it would reduce caseloads and relieve the courts of the punitive function of prosecuting small administrative claims, a duty that is not typical for the judiciary.For citation: Panova I.V., Zaraiskiy A.A.

Современные модели административнопроцессуального регулирования: опыт сравнительно-правового исследования
Authors: Zelentsov Aleksandr , Yastrebov Oleg
Published: June 2024

В статье рассматриваются подходы к пониманию административного процесса и его структуры в России и ряде зарубежных стран. Выявляется возрастание в российской административно-процессуальной науке интереса к разработке «синтезирующей» общей теории административного процесса, в том числе на основе интегративной методологии. В этом контексте раскрывается специфика подходов к его пониманию в зарубежных странах и концептуализируются две основные кодификационные модели административно-процессуального регулирования: модель раздельной кодификации, предполагающая регулирование административных процедур и административного судебного процесса (административного судопроизводства) в двух самостоятельных актах, и модель общей (единой) кодификации, которая характеризуется объединением этих видов административного процесса в одном кодифицирующем акте. Особенное внимание уделяется реализации модели общей кодификации административных процедур и административного судопроизводства. В рамках этой модели административный процесс отождествляется исключительно с административным судопроизводством. В свою очередь, возрастает тенденция к использованию модели общей кодификации, объединяющей в одном кодексе принципы и нормы, которые регламентируют и административные процедуры, и административное судопроизводство. Выявляются особенности юридической техники при проведении такой кодификации,анализируется уровень системной целостности этих единых кодифицирующих актов с позиций интегративной методологии общей теории административного процесса. Логика исследования и практический интерес предопределили необходимость внимательного изучения опыта реализации модели единой кодификации в государствах постсоветского пространства и определения места производства по делам об административных правонарушениях в национальных административно-процессуальных системах. Исследование опыта использования моделей единой кодификации и его осмысление создают дополнительные стимулы и предпосылки для развития интегративной концепции административного процесса, понимаемого как целостное явление в единстве его юрисдикционной и не юрисдикционной (позитивной) составляющих. В статье раскрываются особенности применения интегративной методологии к пониманию и интерпретации административного процесса в российской науке и проблемные вопросы построения на ее основе общей теории административного процесса.Дляцитирования: ЗеленцовА.Б., Ястребов О.А.

Физические свойства тканей зуба
Authors: Муслов С.А. , Арутюнов С.Д.
Published: June 2024

Изменение физических свойств может являться предиктором заболеваний зуба. Поэтому исследование физических параметров зубных тканей имеет клиническое значение, несет информацию о их состоянии и подлежит к применению в диагностических и лечебных целях. Кроме того, оно имеет научную ценность, поскольку физические характеристики являются структурночувствительными и их знание помогает понять сложную многоуровневую структуру дентина и эмали как биологических композитов и гетерогенных сред. В данной монографии авторы объединили известные литературные данные о физических свойствах твердых тканей зуба – эмали и дентина: механических, биоэлектрических, теплофизических, оптических, акустических и радиологических. Также оно содержит результаты собственных исследований и сведения о ряде стоматологических материалов. Его можно рассматривать как справочное пособие, которое облегчит поиск соответствующих данных студентам, ординаторам и аспирантам для научной работы. Авторы будут благодарны всем предоставившим дополнительные сведения о физических свойствах твердых тканей зуба, которые не вошли в данное издание, но представляют собой научную ценность. Книга предназначена также для слушателей факультетов последипломного образования медицинских вузов и зубных техников и может быть полезно преподавателям медицинской и биологической физики медицинских вузов.
Scalability of MIMO Antennas: Assessing Gain and HPBW for Different Antenna Element Configurations
Authors: Salsabila Salwa , Ryanu Harfan Hian , Nur Levy Olivia , Nugroho Bambang Setia
Published: June 2024

The design of Massive MIMO Antennas presents challenges due to their large size, which can impede the design process. Additionally, the arrangement of multiple antenna elements in Massive MIMO Antennas poses a challenge, as it surpasses the capabilities of simulation software and involves complex procedures. Therefore, to address these issues, a scalability technique utilizing array factor theory is employed to determine the relationship between the configuration of MIMO antennas and the corresponding values of gain and half-power beamwidth (HPBW). By utilizing a simpler MIMO Antenna array with incremental configurations, such as 2x2, 4x4, 8x8, and 16x16 MIMO element schemes, the array factor theory allows for the prediction of the gain and HPBW values for a Massive MIMO Antenna array with a specific configuration. This research aims to explore the scalability process and derive equations that relate the gain and HPBW values to the different MIMO configurations. The designed MIMO antenna arrangement is based on rectangular antennas with truncated corners and circular antennas with X slots, allowing for the investigation of various configurations operating at a frequency of 3.5 GHz.
Analysis of the correlations between ECG components in adolescents both before and after exposure to different types of physical stress in the Subarctic winter conditions
Authors: Irzhak Lev I. , Russkikh Nadezhda G. , Gudkov Andrey B.
Published: June 2024

BACKGROUND: Adaptive responses to harsh environmental conditions of the Arctic may vary not only among adults, but also among children and adolescents. These compensatory reactions are influenced by the predominant type of regulation of the autonomic nervous system. The myocardium and its electrical properties play a significant role in determining how individuals adapt to to environmental conditions.
AIM: To study correlations between PP and TR intervals in adolescents in adolescents undergoing the clinostatic test and the Martinet test during the winter season.
MATERIAL AND METHODS: Twenty cardiac cycles were recorded in 22 adolescents aged 15–16 years in the II standard lead, both at baseline and after conducting the clinostatic and Martinet tests. Durations of the RR and TR intervals were measured and used for the analysis. Statistical processing of the data was performed using the MS Excel tables.
RESULTS: Based on both individual and group data analysis, it has been observed that the duration of RR and TR increases during the clinostatic test, while it decreases during the Martinet test. The extent of these changes in RR and TR varies between the two tests. Specifically, the RR:TR ratios are 1:3.5 during the clinostatic test and 1:2.5 during the Martinet test. These findings suggest a higher likelihood of parasympathetic influences on the electrical properties of the myocardium during the clinostatic test, and sympathetic influences during the Martinet test.
CONCLUSION: Duration of RR and TR intervals increased by 25% and 85%, respectively, in response to the clinostatic test. Conversely, after the Martinet test, the duration of both intervals decreased by 15% and 38%, respectively. These findings suggest that the changes in the duration of RR and TR intervals are influenced by the parasympathetic and sympathetic divisions of the autonomic nervous system, under different types of physical stress. Further research should be conducted in other seasons, particularly during transitional periods such as spring and autumn, to better understand the electrical properties of the myocardium under physical stress.
Interstitial electrical stimulation for middle-aged, and elderly adults with early stages of knee osteoarthritis
Authors: Burmatov N. A. , Sergeev K. S. , Luneva S. N. , Gerasimov A. A. , Kopylov S. A. , Spiridonova N. A.
Published: June 2024

Introduction The adequate, pathogenetically substantiated pain management is essential for treatment of  early stages of deforming osteoarthritis of the knee joint. There is a need to explore the effectiveness and mechanisms of modern methods of electrical therapy and their impact on the quality of life due to close cause-and-effect relationship between the pain, inflammatory and destructive components of osteoarthritis (OA) as one of the most common conditions.

The objective was to evaluate the effect of interstitial electrical stimulation (IES) as a monotherapy in  the  course of conservative treatment of early stages of gonarthrosis based on clinical and biochemical findings.

Materials and methods Radiographic findings, skin electrometry (objective parameters of pain intensity), limb weight-bearing capacity, biochemical parameters of connective tissue matrix degradation in blood serum and 24-hour urine samples, and treatment satisfaction were explored in 43 patients. Patients who received a course of IES were assigned to the treatment group (n = 22) and patients who received standard treatment without IES constituted the control group (n = 21).

Results Electrometric analysis showed a higher effectiveness of pain relief in the treatment group compared to the controls with asymmetry coefficient measuring 3.2 ± 0.31 versus 1.9 ± 0.4 at p > 0.05. The weight‑bearing scored 3.59 ± 0.34 versus 3.26 ± 0.2 at p > 0.05. The treatment group showed shorter treatment length with 13.21 ± 1.2 days versus 18.3 ± 1.2 days in the control group at p > 0.05 and a higher degree of satisfaction with outcomes scored 96.2 ± 2.59 in the treatment group versus 86.2 ± 3.17 in the control group. A statistically significant difference (p > 0.05) was established in the levels of free and total hydroxyproline characterizing the different intensity of collagen breakdown in the groups at the end of treatment.

Discussion The IES used as an analgesic and anti-inflammatory therapy was shown to be highly effective with changes in the hydroxyproline level in the media suggesting a chondroprotective effect. The analysis and  comparison of objective parameters demonstrated high effectiveness of IES in the treatment of early stages of gonarthrosis in middle-aged and elderly adults.

Conclusion The IES used for treatment of early stages of gonarthrosis helps pain reducing the intensity of collagen destruction and improving weight-bearing.

Published: June 2024

Introduction Acute hematogenous osteomyelitis can persist as chronic infection in pediatric patients due to delayed diagnosis and treatment. An extended bone defect of the limb caused by osteomyelitic destruction is a rare clinical scenario in pediatric surgery. Metaepiphyseal and articular involvement suggests specific and long-term treatment with a high risk of disability.

The objective was to report a clinical case of a teenager who suffered chronic hematogenous osteomyelitis of the tibial bones and raise awareness of primary diagnosis and treatment.

Material and methods A clinical case of a teenager treated for extensive destruction of the tibial bones caused by chronic hematogenous osteomyelitis is reported. Clinical and functional evaluation of the effectiveness was produced at the stages of treatment.

Results A positive functional result was achieved due to staged surgical treatment including radical debridement of the chronic infection nidus followed by total ankle arthroplasty.

Discussion Acute hematogenous osteomyelitis persisting as chronic infection could be caused either by a wait-and-see strategy when the patient first sought medical help or a long-term follow-up. There is no consensus on the use of reconstruction or replacement of large long bone defects extended to the joints caused by chronic infection. Staged treatment including total joint replacement with custom-made endoprosthesis can be one of the options.

Conclusion Staged surgical treatment including radical debridement followed by delayed total joint replacement with custom-made endoprosthesis provided satisfactory functionality for the limb without signs of infectious and inflammatory activity at a follow-up period of more than a year.

To evaluate the effect of NO added to the oxygenator during CPB on the liver and kidneys in pigs.Methods. The experiment was conducted on 10 pigs undergoing cardiac surgery using cardiopulmonary bypass (CPB). Animals of the experimental group (CPB-NO; n = 5) received NO with the gas mixture supplied to the oxygenator at 100 ppm. Animals of the control group (CPB-control; n = 5) did not receive NO via the oxygenator. The surgery lasted 4 hours and was followed by 12-hour postoperative monitoring. To assess the liver and kidney injury, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, creatinine, neutrophil gelatinase-associated lipocalin (NGAL) were determined at baseline, at weaning from the CPB, 6 and 12 hours after weaning from the CPB. A pathomorphological study of the liver and kidneys was also performed.Results. A long period of CPB deliberately used in our experiment caused liver injury. In the CPB-control group, an increase in the ALT concentration was found: 43 (34; 44) U/l at baseline to 82 (53; 99) U/l 12 hours after CPB, p < 0.05. AST concentration in the CPB-control group increased from 25 (17; 26) U/l at baseline to 269 (164; 376) U/l 12 hours after CPB (p < 0.05). We found no significant increase in ALT and AST concentrations in the CPB-NO group. There were no significant differences in ALT and AST concentrations between CPB-NO and CPB-control groups at all study time points. In the CPB-control group, an increase in the creatinine level was found from 131 (129; 133) μmol/l at baseline to 273 (241; 306) μmol/l 12 hours after CPB (p < 0.05). We found no significant increase in creatinine levels in the CPB-NO group. Creatinine levels in the CPB-NO group were significantly lower than in the CPB-control group 12 h after weaning from CPB: 183 (168; 196) vs 273 (241; 306) μmol/l (p < 0.008). We found no significant differences between the study groups by the NGAL level. Morphology revealed characteristic alterative changes in tissues, circulatory disorders, and inflammatory infiltration of varying degrees of severity, which in combination is a manifestation of the acute damaging effect of CPB. In the CPB-NO group, the severity of pathological changes, measured in points, was lower than in the CPB-control group, but no statistically significant differences were found.Conclusion. NO added to the oxygenator gas mixture reduces liver and kidney injury during prolonged CPB. Further research is required.

Cardiac surgery is associated with high risks of complications, and these risks increase when it comes to aortic surgery because of the technical complexity of the surgeries, the use of cardiopulmonary bypass (CPB) and “circulatory arrest” (CA) that leads to ischemia-reperfusion damage. Abdominal complications in cardiovascular surgery are not the most common complications but are associated with high mortality. Protecting the gastrointestinal (GI) organs from ischemia-reperfusion injury is still a serious problem. According to a study of the organoprotective properties of nitric oxide (NO), its effectiveness in the treatment of diseases of the cardiovascular system, lungs, and kidneys has been proven, and observational results have shown that patients who were administered NO were less prone to complications from the gastrointestinal tract.The aim of the study was to evaluate the protective properties of NO for the intestines during simulated surgery under CPB and hypothermic CA. Methods. The study was conducted on sheep (n = 24). The animals were divided into 4 groups: the “CPB” group with the standard CPB protocol, the “CPB + NO” group with CPB and NO administration, the “CPB + CA” group with the standard CPB and CA protocol, and the group “CPB + CA + NO” with CPB and CA and NO administration. Instrumental and laboratory parameters were monitored at all stages of the experiment to assess the effectiveness and safety of CPB and CA simulation. In intestinal biopsy samples, the changes in the defecation rate, the concentration of a biochemical marker of intestinal ischemia (intestinal enterocyte fatty acid binding protein – i-FABP), and tissue concentrations of adenosine triphosphate (ATP) and lactate were assessed.Results. A higher rate of defecation was established (p = 0.046) in the “CPB + NO” group after CPB compared to the “CPB” group. The concentration of i-FABP in the CPB + NO group after CPB was lower compared to that in the CPB group (p = 0.002), and it was lower in the “CPB + CA + NO” group compared to the “CPB + CA” group (p = 0.033). 1 hour after CPB, the tissue concentration of ATP in intestinal biopsies in the “CPB + NO” group was higher than in the CPB group (p = 0.005).Conclusion. When modeling CPB and CA in the experiment, a positive effect of NO therapy on the intestine was noted: the functional state improved, the concentration of i-FABP decreased, and the concentration of ATP in intestinal biopsies increased.

Published: June 2024

В статье проводится сравнительный анализ нейросетевых и ARIMA-моделей для прогнозирования временных рядов. Оценивается их эффективность и применимость в различных сценариях прогнозирования. Нейросетевые модели, такие как многослойные персептроны и сверточные нейронные сети, обладают высокой гибкостью и способностью улавливать сложные нелинейные взаимосвязи в данных. ARIMA-модели (авторегрессионные интегрированные скользящие средние) предназначены для прогнозирования стационарных временных рядов и часто используются для прогнозирования экономических и финансовых данных. В статье описаны теоретические понятия ARIMA-модели и нейросетевой модели, указаны виды нейросетевых моделей: персептрон, многослойный персептрон, рекуррентные нейронные сети, сверточные нейронные сети и глубокие нейронные сети. Также указаны иные модели прогнозирования: SARIMA и SARIMAX. Для сравнения этих двух моделей применена программа STATISTICA. Также в статье оценена точность двух моделей для различных сценариев прогнозирования с помощью ошибки MAPE.

This article provides a comparative analysis of neural network and ARIMA models for time series forecasting. Their effectiveness and applicability in various forecasting scenarios are assessed. Neural network models such as multilayer perceptrons and convolutional neural networks are highly flexible and capable of capturing complex nonlinear relationships in data. ARIMA (Autoregressive Integrated Moving Average) models are designed for forecasting stationary time series and are often used to forecast economic and financial data. The article describes the theoretical concepts of the ARIMA model and the neural network model, and indicates the types of neural network models: perceptron, multilayer perceptron, recurrent neural networks, convolutional neural networks and deep neural networks. Other forecasting models are also indicated: SARIMA and SARIMAX. To compare these two models, the STATISTICA program was used. Also, this paper evaluates the accuracy of two models for different forecasting scenarios using the MAPE error.

Статья посвящена исследованию перспективы применения платформы программируемых логических интегральных схем (ПЛИС) для реализации алгоритмов машинного обучения с целью высокоскоростной обработки информации из видеопотока. Обосновывается актуальность и значимость темы исследования. Дается краткое обоснование роли и значимости развития применения платформы ПЛИС для реализации алгоритмов машинного обучения. Постулируется, что в настоящее время ПЛИС в среднем более производительна в общих задачах, чем процессор специального назначения. Когда производительность процессора недостаточна и нет готовых схем для решения проблемы, используются ПЛИС, особенно когда речь идет о 100-процентной гарантированной обработке и гарантированной задержке. В отличие от мощного процессора, мощная ПЛИС не требует дополнительной памяти, потребляет меньше энергии и может быть реализована в компактном устройстве. ПЛИС более производительна, но менее гибка с точки зрения реализации некоторых задач. В то же время сфера применения технологии довольно широка. Анализ научной литературы позволил сделать заключение о ее эффективности в различных областях.

The article addresses the prospects of using the FPGA platform for the implementation of machine learning algorithms for the purpose of high-speed processing of information from a video stream. The authors substantiate the relevance and significance of the research topic. A brief justification of the role and significance of the development of the FPGA platform for the implementation of machine learning algorithms is given. It is stated that at present the FPGA is on average more productive in general tasks than a special-purpose processor. When the processor performance is insufficient and there are no ready-made circuits to solve the problem, FPGAs are used. Especially when it comes to 100-percent guaranteed processing and guaranteed latency. Unlike a powerful processor, a powerful FPGA does not require additional memory, consumes less energy and can be implemented in a compact device. FPGA is more productive, but less flexible in terms of implementing some tasks. At the same time, the scope of the technology is quite wide. The analysis of the scientific literature allowed us to conclude about its effectiveness in various fields.

ESTRATÉGIAS DE EVIDENCIAÇÃO NA TRAJETÓRIA DE MERCEDES BAPTISTA
Authors: Santos Taynara Rafaela dos
Published: June 2024

Com o objetivo de evidenciar a trajetória de corpos negros invisibilizados nas artes cênicas, esse artigo irá tratar da trajetória artística da bailarina e precursora da dança afro no Brasil Mercedes Baptista, tendo como base a sua biografia publicada em 2007 por Paulo Melgaço da Silva Jr. e intitulada “Mercedes Baptista: a criação da identidade negra na dança”. A importância do resgate dessa figura se legitima pela ausência ainda constante do nome de Mercedes Baptista no imaginário popular e especializado quando o assunto é dança no Brasil, apesar de seu pioneirismo nesse âmbito, a bailarina é pouco citada pelos pesquisadores da área que se debruçam sobre o tema. Por isso, faz-se necessário a partir de sua biografia, trazer a tona a vida e carreira dessa artista negra.

Published: June 2024

Objetiva-se narrar e analisar o  processo de criação e organização do acervo da professora quilombola Maria Enilda Marques Boeira, desde 2023 guardado no Arquivo da Faculdade de Educação da Universidade Federal do Rio Grande do Sul, como resultado da investigação intitulada “Faculdade de Educação e Movimento Negro Educador”. A professora quilombola pertence à Comunidade do Limoeiro, localizada em Bacupari/Palmares do Sul/RS, e a iniciativa do acervo surgiu da relação estabelecida em pesquisa com a Professora Doutora Petronilha Beatriz Gonçalves e Silva, na qualidade de pesquisadora do território quilombola e intelectual  ativista do Movimento Negro Educador (GOMES, 2017). A metodologia é de abordagem qualitativa, com uso de aproximação por visitas aos territórios, entrevistas, organização e análise documental.  Os resultados parciais apontam a potência das ações de confluências de saberes entre uma pesquisadora da educação superior e uma professora da educação básica, ambas forjadas na docência e na pesquisa comprometida com a emancipação das pessoas negras no Rio Grande do Sul, através do combate ao racismo e à supremacia branca. Utiliza-se a categoria afeto, a partir das leituras de bell hooks, como chave para pensar tais registros.
