Vortex beams (VBs) carrying orbital angular momentum (OAM) have shown promising potential in enhancing communication capacity through the possession of multiple multiplexing dimensions involving the OAM mode, polarization, and wavelength. Although many research works on multidimensional multiplexing have been conducted, the (de)multiplexer compatible with these dimensions remains elusive. Following the expanded concept of the Pancharatnam–Berry (PB) phase, we designed a polarization-dependent phase-modulation metasurface to phase-modulate the two orthogonal linearly polarized components of light, and two Dammann vortex gratings with orthogonal polarization responses were loaded to simultaneously (de)multiplex OAM mode and polarization channels. As a proof of concept, we constructed a 16-channel multidimensional multiplexing communication system (including two OAM modes, two polarization states, and four wavelengths), and 400 Gbit/s quadrature-phase shift-keying (QPSK) signals were transmitted. The results demonstrate that the OAM mode and polarization channels are successfully (de)multiplexed, and the bit-error-rates (BERs) are below 1.67 × 10−6 at the received power of −15 dBm.

Objectives

Opioids are commonly used to manage pain, despite an increased risk of adverse events and complications when used against recommendations. This register study uses data of osteoarthritis (OA) patients with joint replacement surgery to identify and characterize problematic opioid use (POU) prescription patterns.

Methods

The study population included adult patients diagnosed with OA in specialty care undergoing joint replacement surgery in Denmark, Finland, Norway, and Sweden during 1 January 2011 to 31 December 2014. Those with cancer or OA within three years before the first eligible OA diagnosis were excluded. Patients were allocated into six POU cohorts based on dose escalation, frequency, and dosing of prescription opioids post-surgery (definitions were based on guidelines, previous literature, and clinical experience), and matched on age and sex to patients with opioid use, but not in any of the six cohorts. Data on demographics, non-OA pain diagnoses, cardiovascular diseases, psychiatric disorders, and clinical characteristics were used to study patient characteristics and predictors of POU.

Results

13.7% of patients with OA and a hip/knee joint replacement were classified as problematic users and they had more comorbidities and higher pre-surgery doses of opioids than matches. Patients dispensing high doses of opioids pre-surgery dispensed increased doses post-surgery, a pattern not seen among patients prescribed lower doses pre-surgery. Being dispensed 1–4,500 oral morphine equivalents in the year pre-surgery or having a non-OA pain diagnosis was associated with post-surgery POU (OR: 1.44–1.50, and 1.11–1.20, respectively).

Conclusions

Based on the discovered POU predictors, the study suggests that prescribers should carefully assess pain management strategies for patients with a history of comorbidities and pre-operative, long-term opioid use. Healthcare units should adopt risk assessment tools and ensure that these patients are followed up closely. The data also demonstrate potential areas for further exploration in improving patient outcomes and trajectories.

Published: February 2023

End-of-line (EOL) quality assurance of finished components has so far required additional manual inspections and burdened manufacturers with high labor costs. To automate the EOL process, in this paper a fully AI-based quality classification system is introduced. The components are automatically placed under the optical inspection system employing a robot. A Convolutional Neural Network (CNN) is used for the quality classification of the recorded images. After quality control, the component is sorted automatically in different bins depending on the quality control result. The trained CNN models achieve up to 98.7% accuracy on the test data. The classification performance of the CNN is compared with that of a rule-based approach. Additionally, the trained classification model is interpreted by an explainable AI method to make it comprehensible for humans and reassure them about its trustworthiness. This work originated from an actual industrial use case from Witzenmann GmbH. Together with the company, a demonstrator was realized.
Statistical Learning of Distractor Suppression Downregulates Prestimulus Neural Excitability in Early Visual Cortex
Authors: Ferrante Oscar , Zhigalov Alexander , Hickey Clayton , Jensen Ole
Published: February 2023

Visual attention is highly influenced by past experiences. Recent behavioral research has shown that expectations about the spatial location of distractors within a search array are implicitly learned, with expected distractors becoming less interfering. Little is known about the neural mechanism supporting this form of statistical learning. Here, we used magnetoencephalography (MEG) to measure human brain activity to test whether proactive mechanisms are involved in the statistical learning of distractor locations. Specifically, we used a new technique called rapid invisible frequency tagging (RIFT) to assess neural excitability in early visual cortex during statistical learning of distractor suppression while concurrently investigating the modulation of posterior alpha band activity (8–12 Hz). Male and female human participants performed a visual search task in which a target was occasionally presented alongside a color-singleton distractor. Unbeknown to the participants, the distracting stimuli were presented with different probabilities across the two hemifields. RIFT analysis showed that early visual cortex exhibited reduced neural excitability in the prestimulus interval at retinotopic locations associated with higher distractor probabilities. In contrast, we did not find any evidence of expectation-driven distractor suppression in alpha band activity. These findings indicate that proactive mechanisms of attention are involved in predictive distractor suppression and that these mechanisms are associated with altered neural excitability in early visual cortex. Moreover, our findings indicate that RIFT and alpha band activity might subtend different and possibly independent attentional mechanisms.

SIGNIFICANCE STATEMENTWhat we experienced in the past affects how we perceive the external world in the future. For example, an annoying flashing light might be better ignored if we know in advance where it usually appears. This ability of extracting regularities from the environment is called statistical learning. In this study, we explore the neuronal mechanisms allowing the attentional system to overlook items that are unequivocally distracting based on their spatial distribution. By recording brain activity using MEG while probing neural excitability with a novel technique called RIFT, we show that the neuronal excitability in early visual cortex is reduced in advance of stimulus presentation for locations where distracting items are more likely to occur.

The complement system which is part of the innate immune response against invading pathogens represents a powerful mechanism for killing of infected cells. Utilizing direct complement recruitment for complement‐mediated elimination of HIV‐1‐infected cells is underexplored. We developed a novel therapeutic modality to direct complement activity to the surface of HIV‐1‐infected cells. This bispecific complement engager (BiCE) is comprised of a nanobody recruiting the complement‐initiating protein C1q, and single‐chain variable fragments of broadly neutralizing antibodies (bNAbs) targeting the HIV‐1 envelope (Env) protein. Here, we show that two anti‐HIV BiCEs targeting the V3 loop and the CD4 binding site, respectively, increase C3 deposition and mediate complement‐dependent cytotoxicity (CDC) of HIV‐1 Env‐expressing Raji cells. Furthermore, anti‐HIV BiCEs trigger complement activation on primary CD4 T cells infected with laboratory‐adapted HIV‐1 strain and facilitates elimination of HIV‐1‐infected cells over time. In summary, we present a novel approach to direct complement deposition to the surface of HIV‐1‐infected cells leading to complement‐mediated killing of these cells.

Authors: Bravo Jorge
Published: February 2023

Radiation detection systems allow registering sum peaks as a consequence of their finite time resolution. In order to interpret the accumulated spectra properly it is necessary to be able to predict the presence of these sum peaks in order to identify correctly the peaks that are observed in the spectra, especially those of very low intensity. In this work a detailed analysis of the presence of sum peaks of order two is presented for the case of energy dispersive X-ray fluorescence spectrometry.

Published: February 2023

The integration of the environmental dimension is crucial in industrial activity. Designers should integrate the new environmental constraints to adapt their approaches and methodologies in the framework of eco-innovation of industrial products and consumer goods. This paper proposes a new method integrating ecological aspects into the innovation process. We analyze different tools proposed in the literature to determine the relevant parameters to consider for assuring an efficient methodology. Relevant parameters are related to different phases in the lifecycle of the product and it is proposed to link them to different impacts on the environment. Actions are set up to guide engineers in the early phase of concept generation for eco-innovation. The methodology is essentially based on functional analysis, energy analysis and physical analysis of products and problem solving tools stemming from Triz theory.

Authors: P Sukhov Peter , P Yepishev Vitaly , P Sukhov Konstantin
Published: February 2023

The aim of the work is to check the possibility of detecting degradation of the surface of a geostationary satellite according to B, V, R photometry during a long stay of the satellite in space. The change in reflective characteristics in three filters of four geostationary satellites with different platforms over a time interval of 3-9 years is studied. These are geostationary satellites with Eurostar E3000, SSL-1300, Spacebus-4000B2 and Express-2000 buses. It is revealed that the nature of the change in the reflectivity of different geostationary satellites is not the same. Spacecraft materials used for the surfaces of geostationary satellites built in the second decade of the 21st century are more resistant to the rigors of space than those used for satellites built in the late 20th century. The presented results show that the photometric method works and can be used to detect surface degradation of spacecraft.

Published: February 2023

We aimed to examine the effects of brain ischemia-reperfusion (IR) especially on serum parameters or liver enzymes, free radicals, cytokines, oxidatively damaged DNA, spermidine/spermine N-1-acetyltransferase (SSAT). The effects of addition of putrescine on IR will be evaluated in terms of inflammation and oxidant-antioxidant balance in liver.

The study was conducted on 46 male Albino Wistar rats weighing 200–250 g. The rats were grouped into: 1-Sham group (n = 6). 2-IR group (n = 8): The carotid arteries were ligated for 30-min and reperfusion was achieved for 30-min under general anesthesia. 3-Ischemia + putrescine + reperfusion group (IPR) (n = 8): Unlike the IR group, a single dose of 250 μmol kg−1 putrescine was given by gavage at the beginning of reperfusion. In putrescine treatment groups in addition to the procedures performed in the IR group a total of 4 doses of 250 μmol kg−1 putrescine were given at 12-h intervals, with the first dose immediately after 30-min reperfusion (4-IR+putrescine group (IR+P1) (n = 8)); 3 h after the 30-min reperfusion (5-IR+putrescine group (IR+P2) (n = 8)); 6 h after the 30-min reperfusion (6-IR+putrescine group (IR+P3) (n = 8)). ALT, AST, ATP, NO, SSAT, 8-OHdG levels were analyzed in the serum, and liver samples. NF-κB and IL-6 levels were analyzed in the liver samples.

Brain IR causes inflammatory, oxidative and DNA damage in the liver, and putrescine supplementation through gavage reduces liver damage by showing anti-inflammatory and antioxidant effects.

ABSTRACT In Mexico, Creole corn has presented problems related to seed rot. Therefore, the objective of this study was to determine the frequency of fungi associated with Creole corn seeds. From January to February 2019, 13 Creole corn samples were collected from several localities in Guerrero, Mexico. The samples were processed in PDA culture medium and the frequency of each fungus was estimated based on cultural characteristics and taxonomic keys. Considering symptomatic corn seed samples, Fusarium oxysporum was recorded in eight samples at 97.2%, followed by F. graminearum, isolated from race “Olotillo 1” at 94.4% and from race “Cónico pepitilla” at 58.3%. Phomopsis sp. was isolated at 100% from race “Olotillo 2”. Gibberella moniliformis was isolated from “Elotes Occidental 1” at 83.3%, while the least frequent isolate (19.4%) from “Pepitilla” was Sarocladium strictum, which was recorded in three samples at the low values of 11.1% and 2.8% for races “Arrocillo 2” and “Pepitilla”, respectively; Talaromyces variabilis was found in two samples at 11.1% and 2.8% from “Arrocillo 2” and “Cónico pepitilla”, respectively; Stenocarpella macrospora was isolated at 72.2% from “Pepitilla”. Aspergillus flavus was obtained from “Cónico Pepitilla” at 16.7%, while Setosphaeria turcica and Emericella sp. were less frequently isolated. Considering asymptomatic seeds of race “Cónico pepitilla”, F. oxysporum was isolated at 8.3%, Fusarium acuminatum at 8.3% and Gibberella moniliformis at 41.7%; from asymptomatic seeds of “Olotillo 1” and “Olotillo 2”, Phomopsis sp. was isolated at 50% and Rhizoctonia solani at 50%, respectively. In the present study, the fungi F. oxysporum, Phomopsis sp., G. moniliformis and F. graminearum were most frequently associated with Creole corn seeds.
Nuevas espiritualidades, neoliberalismo y subjetividad
Authors: Vergara René Gallardo , Saavedra Rodrigo Navarrete
Published: February 2023

Resumen: En el trabajo analizamos críticamente el campo de la New Age y las nuevas espiritualidades, en cuanto espacio privilegiado de subjetivación neoliberal y remodelación de vínculos comunitarios. Damos cuenta del profundo influjo que dichas tendencias tienen en la constitución de los individuos, que lejos de configurar subjetividades inocuas e intrascendentes políticamente hablando, esculpe sujetos en una constante embriaguez de sí, consumidores compulsivos de productos y experiencias espirituales o empresarios-gestores de sus activos y capitales espirituales. Destacamos los efectos de psicologización y despolitización que estas tendencias promueven, así como la reconfiguración de la comunidad al servicio de un proyecto centrado en el engrandecimiento del self.
Antigos mestres do espaço, novos protetores dos homens: formando um povoado na Amazônia brasileira
Authors: Boyer Véronique
Published: February 2023

Resumo: Com base em uma pesquisa perto de Santarém (Pará), o artigo busca questionar a impressão de impermeabilidade entre “santos” e “encantados”, como foi enfatizada pela antropologia amazônica. Analisando as conexões entre as duas categorias, e a sua divisão em subcategorias, sugere-se que sua alternância tece uma narrativa sobre a emancipação dos seres humanos vis-à-vis das forças previamente presentes: depois de ter negociado com os encantados o direito de morar num local, os homens convidam os santos em suas próprias residências, como se a aliança com esses novos protetores permitisse afrouxar o domínio dos antigos mestres do espaço. Nessa história situada, os encantados mapeiam o espaço geográfico vivenciado enquanto santos simbolizam o tecido de relações sociais forjados nele entre os seres humanos.
Squabbles between the Jesuits and the Franciscans: a historical review of policies of two christian orders in Japan
Authors: Chen Xizi
Published: February 2023

Abstract: Throughout the history of Christianity in Japan, tension and conflict have persisted between the Jesuits and Franciscans. At face value, this appears to be due to their different readings of the policies of Rome and varied approaches to apostolic work. However, upon closer examination, politics also played an important role. Behind the two orders were two rival maritime powers - Portugal and Spain, whose fellow countrymen’s feelings of national sentiment may occasionally have outweighed their interests in the mission in Japan. In an attempt to keep the peace, Rome had issued the Patronatus missionum. However, it intensified the conflict and rendered the situation into an irreparable state of disarray. This eventually caused heavy losses to the whole mission. For a better understanding, in this thesis I summarize the following arguments between the Jesuits and Franciscans. The first, and most salient, argument pertains to commerce; the second pertains to the separation of parishes; the third to their apostolic approaches, and the final argument is on their practical policies. It is also worth mentioning that the relationship between the Jesuits and the Franciscans was not eased by the 26-person Nagasaki martyrdom incident. Indeed, this was a heavy loss.

ABSTRACT This exploratory descriptive research aims to analyze the implementation of the School Health Program in the Federal District, in the period before and during the COVID-19 pandemic. The data were produced from February to April 2022 through documentary research and application of an online questionnaire with professionals from the Primary Health Care (PHC) teams within the scope of the Primary Care Qualification Program of the Federal District-QualisAPS. The databases of the National Institute of Educational Studies and Research Anísio Teixeira, the Information System for Primary Care and the QualisAPS Platform were accessed on the actions developed from 2018 to 202, the structuring of the program, and its inclusion in the action plans of family health and oral health teams. Through descriptive statistics and content analysis it was evident an increase in the adhesion of schools to the PSE and a predominance of records related to oral health and vaccine verification, in both periods, with quantitative reduction due the pandemic period. The reality of the Federal District reveals that the interrelation of the Program with PHC and the support of QualisAPS enable a continuous planning process, bringing prospects for strengthening the actions.

Published: February 2023

ABSTRACT The School Health Program aims to build healthy schools. This qualitative case study aimed to identify and understand how professionals involved in the School Health Program behave in the integration based on their inclusion in the recommended activities. The consensus was reached with experts to develop a matrix of indicators after building the Program’s logical model, resulting in a semi-structured roadmap. Twenty-five interviews were held in the Basic Health Units, Elementary Schools, and the Regional Health and Education Administrations. The practices were multisectoral, with no combined efforts and effective co-participation, planned by a single sector or professional, the existing gaps are recognized as much as the importance of the program, and the practices are implemented with a low bond between teams. The fragmented perception of students’ problems hinders this integration.

Published: February 2023

ABSTRACT The study aims to show the evolution of the percentage of schools adhering to the School Health Program (PSE) that carried out a collective activity on the Promotion of Adequate and Healthy Eating (PAAS) over the last five years and verify if there is a difference in this indicator according to adhesion to the Healthy Growth Program (PCS). Ecological study, developed with data registered in the Health Information System for Primary Care (SISAB). The performance of collective actions on PAAS from 2017 to 2019 increased. In 2020, there was a reduction in the actions carried out; and in 2021 there was an increase in actions carried out compared to 2020. The municipalities that received additional funds from the PCS had the highest percentages of schools carrying out collective activities on PAAS. The implementation of PAAS actions did not occur homogeneously according to the Brazilian macro-regions. It is concluded that there has been a strengthening of PAAS actions within the scope of the PSE, with a significant reduction of this action in the context of the COVID-19 pandemic. Getting additional resources from the PCS favored the development of actions on PAAS, which reinforces the importance of regular financial transfers.

Published: February 2023

RESUMO A educação em saúde constitui processo de produção do conhecimento que amplia a consciência crítica e reflexiva das pessoas. O objetivo do estudo foi analisar as práticas educativas de nutricionistas no Programa Saúde na Escola relacionadas com as perspectivas educativas. Estudo qualitativo, explicativo, realizado por meio de entrevistas semiestruturadas com 22 nutricionistas em 10 municípios-sede de regiões de saúde do estado do Piauí. As entrevistas foram transcritas e analisadas, segundo análise de conteúdo de Bardin. Após essa análise, foram submetidas ao software IRaMuTeQ e apresentadas em nuvens de palavras e análise de similitude. A prática educativa foi relacionada como orientação, repasse e intervenção. O planejamento de ações, o diagnóstico situacional, o tempo e os recursos são considerados nos relatos para execução das práticas. Quanto às condições de saúde, nem sempre as escolas informam aos profissionais as demandas de ações. Para os partícipes, a saúde é protagonista no enfrentamento dessas ações, e há ausência da intersetorialidade entre educação e saúde. As práticas educativas, de modo geral, acontecem pautadas na transmissão do conhecimento, mudanças de comportamentos e de cunho autoritário. O estudo sugere outra perspectiva de educação em saúde, com a participação da sociedade, centrada na autonomia do sujeito.

RESUMO A promoção da atividade física integra uma das 13 ações do Programa Saúde da Escola (PSE). O objetivo deste estudo foi descrever as ações de práticas corporais e atividade física registradas em três ciclos de adesão (2014-2015, 2017-2018 e 2019-2020), por região e Unidade Federativa (UF). Por meio de análise descritiva, foram apresentados os números de ações realizadas em cada ano, ciclo, UF e região. Observou-se aumento de municípios e escolas nas adesões a cada ciclo em todas as regiões. Considerando o total de municípios compreendidos em cada região, 100% dos municípios do Nordeste aderiram ao PSE nos dois últimos ciclos. O Sudeste teve a menor proporção de municípios aderidos em todos os ciclos. Em cada ciclo, a maior parte das ações foi realizada no primeiro ano na maioria das UF. Nacionalmente, houve aumento do número de ações em todos os ciclos, com destaque para o Nordeste e o Sudeste. Do primeiro para o terceiro ciclo, esse aumento foi maior no Sudeste e no Sul. Minas Gerais, Bahia, Ceará e Maranhão totalizaram quase metade das ações. Os resultados evidenciaram diferentes nuances na implementação da promoção da atividade física e podem subsidiar tecnicamente gestores e técnicos vinculados ao PSE.

ABSTRACT This excerpt of a master’s thesis aims to describe the construction of proposals for the prevention, combat, and attention to intrafamily and school violence against child and adolescent students in a suburban district of a municipality in the inland region of Bahia, Brazil. A qualitative, descriptive, exploratory study was conducted through action research. The social stakeholders of the research were the school community, the family, and health professionals. Data were collected by systematic observation, conversation circles, and seminars adopted for situational diagnosis and the development of interventions. Data was interpreted through content analysis. The activities revealed the relevance of the work developed in intersectoral and multidisciplinary qualified network, resulting in behavioral changes of adolescents at school and in the family, their leadership in educational workshops for a peace culture, the implementation of a conflict mediation space at school, the establishment of a physical activity project, drawing parents closer to the school, and raising the awareness toward better possibilities of non-violent domestic education. We conclude that the interventions initiated a movement of change of practices and dialogue of the several district services, resulting in a gradual construction of peace territories in the school and the community.

ABSTRACT: Araucaria angustifolia characterizes mixed Ombrophilous Forests. This Paraná pine tree has been of great economic, cultural and social importance for southern Brazil. Its cutting is restricted, as it is threatened with extinction and the use of its seed has been encouraged. This study highlights scientific research on this conifer by bibliometric analysis and reviews trends in new research on its seed and some of its food applications. The Web of Science© database revealed 620 scientific articles and the bibliometric analysis through VOSviewer showed the worldwide interest in growing. The increase in research in the areas of silviculture, phytoscience and ecology reflects the concern with the preservation of “Matas das Araucárias”. Concurrently, research in food science and technology has increased, as pine nut seed can produce starch-rich food flour with low glycemic response and source of dietary fiber and some minerals. Also, along with its husk, provide bioactive compounds with potential application in the special food, active/smart and reinforced packaging and even pharmacological industries.

RESUMO As tecnologias digitais transformaram a forma de produzir e adquirir conhecimento. Com a pandemia, fez-se evidente a urgência de utilizá-las mais significativamente no ambiente escolar. Mas ainda é preciso que o professor passe pela experiência de utilizar tais tecnologias para, então, trabalhar com elas. Partindo da noção de que é necessário desenvolver novas habilidades para ser letrado digitalmente (KARCHMER-KLEIN; SHINAS, 2012), e considerando as identidades como sendo moldadas pela experiência (IVANIC, 1998), este artigo busca entender como cinco alunos de um programa de Pós Graduação em Linguística Aplicada, já professores experientes, ao escreverem, constroem suas identidades e refletem sobre a relação das tecnologias digitais com a escola. Para tanto, foram analisados os diários produzidos durante uma aula destinada ao letramento digital, na qual os alunos liam a teoria e experimentavam uma ferramenta digital. Conclui-se que a curiosidade é um dos elementos fundamentais para desenvolver o letramento digital e o pensamento computacional, e que é através das tentativas que o educador aprimora seus conhecimentos e adquire confiança para incorporar novas ferramentas digitais em sala de aula.

Published: February 2023

ABSTRACT Introduction: The physical fitness of college students incites an alarming concern. Although the importance of fitness tests for college students has improved, the overall level and range are low. This requires colleges and universities to increase sports awareness and enrich their exercise methods. Relevant scientific articles can assist universities in promoting college students' physical and mental health. Objective: Analyze the effects of exercise on college students' physical fitness. Methods: We randomly selected 30 college students with normal cardiopulmonary function as volunteers for the research. Walking for 30 minutes was promoted, followed by a rapid walking test for college students. Factors such as breathing, heart rate, and other indicators during exercise were collected, measured, and evaluated. Results: The students in the research had good correlations with each index of oxygen uptake, CO2 exhalation, ventilation ratio, and heart rate during uniform running. The value of the indices tended to stabilize about 5 minutes after exercise. Conclusion: Active running exercise can improve aerobic endurance in college students. Physical fitness was improved in this trial. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
ENHANCEMENT BY DIET AND AEROBIC EXERCISE IN PROFESSIONAL ATHLETES
Authors: Wang Chunfang
Published: February 2023

ABSTRACT Introduction: Body weight regulation in sports competitions is an essential factor affecting the physical capacity of athletes. Especially in high-level events, the role of weight loss is significant in improving the competitive status. Weightlifters have high anaerobic capacity, high aerobic capacity, high flexibility, and less body fat. In all regular competitions, weightlifters compete against competitors of the same weight class. Objective: This paper investigates the effect of moderate aerobic exercise on weight loss in athletes and the effects of related biochemical parameters. Methods: Twenty weightlifters were randomly selected to conduct a questionnaire survey. The athletes performed aerobic exercises for eight weeks. The collection method and mathematical statistics were used to study body shape and constitution, blood indices, and other relevant data about weightlifters in China. Results: The effect of aerobic exercise on improving the athletes' physical fitness is discussed. The results showed that body weight, waist circumference, hip circumference, and body mass index decreased the most (P<0.05). Waist-to-hip ratio, waist-to-height ratio, hip-to-height ratio, and BMI significantly decreased (P<0.05). There was no significant change in height and fat index (P>0.05). Conclusion: 8 weeks of aerobic exercise and an appropriate diet can significantly improve the body shape index, physical index, and biochemical index of athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Published: February 2023

ABSTRACT Introduction: Lifting weights requires muscular capacity, strength, and determination. Strength training for weightlifters stimulates the nervous system and promotes muscle hypertrophy. Strength training is the most important point in weightlifters' training. Objective: Explore the effects of abdominal core strength training on the physical fitness of weightlifters. Methods: 26 weightlifters were selected by random sampling. The athletes participated in physical training for 26 weeks. Athletes' physical fitness was measured before and after training. Tests included the y-Balance test, stability exercises, and abdominal center strength. After each training session, the players used foam rollers and baseballs for recovery training. After the experiment was completed, the data was analyzed by mathematical statistics. Results: The left lower limb stability of the weightlifters was better than the right in the Ans direction; in all three directions, there were extremely significant ipsilateral differences before and after the experiment(P<0.05). There was a highly significant difference between the level and super level of the ipsilateral upper limbs of the athletes (P<0.05). Conclusion: Weightlifters who practiced abdominal core strength exercises significantly improved the dynamic stability of the lower limbs. Young male weightlifters' upper limb motion stability is more symmetrical during abdominal core strength exercises. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: In training, fatigue and recovery are antagonistic factors. Physical rehabilitation of athletes and elimination of sports fatigue have gradually become essential factors in improving competitiveness. Muscle relaxation exercises can reduce badminton players' physical effort, allowing them to recover quickly. Objective: Analyze muscle relaxation's effect on fatigue relief until the normalization of physical strength in badminton players. Methods: Twelve badminton players were grouped in cross-sectional tests. During the three weeks of physical training, players performed two training methods: muscle relaxation and complete rest. Laboratory analysis encompassed blood biomarkers such as urea and creatine kinase. Data were collected before and after the interventions, confronted, and studied mathematically and statistically. Results: The proportions of leukocytes and lymphocytes in the muscle relaxation group after resistance exercise were lower than before. The decrease of morning leukocytes in the muscle relaxation group on the second day was less than in the resting group. The recovery effect of the lymphocyte ratio was also better. After special strength training, the value of creatine kinase was significantly higher than before exercise in both the muscle relaxation group and the complete rest group. Conclusion: Muscle relaxation can reduce exercise fatigue in badminton players. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Peng Fentian
Published: February 2023

ABSTRACT Introduction: The essential characteristics of the unique fitness of sport dancing are composed of the athletes' skill, quality, and physical characteristics. All are directly affected by proper abdominal core strength training. Kick strength is an important variable for controlled balance in lower limb elevation. It is produced by the combined action of the pelvic girdle and thigh muscle groups, beginning at the abdominal core. Objective: This paper explores the effect of abdominal core strength training on the quality of kicking movement in dance sports work. Methods: Forty-six college students majoring in sport dance were randomly selected as volunteers for the research. Randomly divided into control and experimental group, they participated in the experiment for four weeks. The experimental group added a specific strength exercise for the abdominal core at each class, while the control group followed only with the routine exercises. Several indicators of the athletes were tested before and after the end of the experiment. The collected variables went through the statistical methodology and data analysis. Results: The experimental group members showed significantly higher kicks than those of the control group (P<0.05). The balance and stability scores in the experimental group were also significantly higher (P<0.05). Conclusion: Abdominal core strength training significantly affects the quality of lower limb lifting movements in sports dance practitioners and significantly affects the overall performance improvement of athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Published: February 2023

ABSTRACT Introduction: Soccer is watched by hundreds of millions of fans worldwide, in more than 1.5 million teams and 300,000 clubs worldwide, by men and women, children and adults of all levels of expertise. Demanding high performance from its practitioners, achieved only with the strong scientific basis of its technicians by constantly updated research. Objective: Study the results of extensor strength training with plyometrics exercises on the motor function of soccer players' lower limbs. Methods: An experiment with 30 soccer players as research volunteers was performed by randomly dividing them into high load plyometric training group (PHL, 20% of body weight), low load plyometric training group (PLL, 10% of body weight), and control group (CON) for various physiological tests before and after training. Results: Lower limb muscle mass in the PHL group increased significantly; creatine kinase (CK) changes were not statistically significant; regarding isokinetic muscle strength performance, the PHL group showed a significant improvement in peak torque at 60°/s and 180°/s, while the PLL group obtained only a significant improvement at 180°/s. Conclusion: Plyometric exercise promoted a significant improvement in isokinetic muscle strength of the lower extremity of soccer players; its training with different weights did not cause muscle damage. A progressive training load is recommended for athletes with low muscle strength during the initial training phase. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
The monodominance of Acuri in Pantanal formations: allelochemical effects of its leaves and the presence of Acurizais

Abstract The presence of monodominant vegetative formations almost exclusively composed of Acuri palm trees (Attalea phalerata) stands out in some regions of the Pantanal Sul-Mato-Grossense. These formations are generally associated with anthropic, edaphic and/or hydrological factors. However, little is known about the effect of allelopathy on the formation and maintenance of these areas. Herein, we investigated the chemical composition of A. phalerata aqueous leaf extract and the potential allelopathic effects on germination and growth of target L. sativa, L. esculentum and S. obtusifolia species. Thus, extracts at concentrations of 0, 2.5, 5, 10, 15, and 20% were used for germination and growth bioassays with a completely randomised design in a germination chamber and greenhouse. The results showed that the A. phalerata extracts negatively affected the germination speed index and mean germination time of the target species and positively affected seedling length under controlled conditions and were also stimulated in the greenhouse. Thus, the formation of Acurizals can be related to the presence of secondary metabolites in the leaves, in addition to other environmental factors.
Lefebvre y el giro espacial en antropología urbana: Notas para una epistemología del espacio vivido
Authors: Espinosa Horacio
Published: February 2023

Resumen La antropología urbana es una disciplina a la que le costó nacer. Su origen, en el seno del departamento de Sociología de la Escuela de Chicago, sitúa a la disciplina en una posición de dependencia frente a la sociología urbana. Sin embargo, el enfoque etnográfico de la Escuela de Chicago dura poco, fagocitado por una sociología estadística y cuantitativa, que durante mucho tiempo será la dominante. Por su parte, los antropólogos llegan tarde a la ciudad, ya entrados los años 1960’s, y cuando llegan, vacilan entre hacer antropología en la ciudad o antropología urbana. Es en las décadas de 1970 y 1980 cuando se intenta dibujar un marco epistemológico para la antropología urbana, que ha ingresado al siglo XXI huérfana de un objeto de estudio claro. Este es el diagnóstico del problema respecto al cual el filósofo urbano Henri Lefebvre puede darnos algunas luces. Usando fragmentos de etnografías propias como ejemplo, el presente texto realiza una relectura antropológica de algunos conceptos lefebvrianos como “espacio vivido” y “vida cotidiana”, resaltando su carácter socialmente transformador; igualmente, a través de una serie de reflexiones epistemológicas, se tiene la intención de avanzar en la formulación de algunas conclusiones metodológicas relevantes para la construcción de una etnografía urbana con perspectiva crítica.
Poetic opening stanched by violence
Authors: Pereira Pedro Paulo Gomes
Published: February 2023

Abstract This article reflects on violence committed against travestis, examining a series of murders of travestis, together with narratives regarding violence, to see where these events and stories lead, and to formulate related questions. Through this movement, the research develops such questions as: what are the motives behind the violence committed against travesties, and what do these motives tell us? If violence is expressive - in other words, if it tells us something - what is it saying? Can we talk about crimes as being gender-based? If so, how should we consider the relations between gender, sexuality, and violence? What desires are at play? And what do these events tell us about the concept of gender itself?
Perpetual motion: Displacement of travestis from an ethnographic perspective
Authors: Rodrigues André Rocha
Published: February 2023

Abstract Intense mobility is a characteristic observed in the context of travestis who work in sex markets. Studies on the subject usually emphasize that this mobility is related to a project of refinement, social ascension, and greater social, symbolic, and economic well-being, besides serving as a project of transformation and beautification of the bodies. Based on ethnographic work, I argue that, in order to understand the various orders of displacements of travestis, it is necessary to understand such movements as a perpetual motion machine, and not as being determined by imperatives that would necessarily lead to displacements from one place to another in search of something - much less something exceptional. In the observed context, displacements are a way of being in the world. Events occur during the displacements, not because of them.
