Published: December 2022

ABSTRACT: The pelvis, formed by the ilium, ischium and pubis, forms the coxal, which is the largest of the flat bones of the skeleton, with an important role in the physiology of birth. Vastly studied in domestic animals, there is still much to be investigated regarding the anatomical classification in wild animals, mainly aiming to improve the understanding of the reproductive management of the species. Tamandua tetradactyla is one of these species in which morphological studies are still scarce, especially when it comes to reproductive aspects. In this context, we carried out the pelvimetry of T. tetradactyla using radiographic images to anatomically and obstetrically classify the pelvis of this species, classifying it as dolicopelvic, with evidence of homoscedasticity of the samples. Verification of the existence of a relationship between the variables studied by the statistical method of Pearson coefficients showed positive correlations of high intensity for the diameters studied (P < 0.01). Thus, we believed that our findings may support future reproductive studies in this species.

ABSTRACT: The increase in sheep production is directly related to the health status of the flock. Brazil is one of the largest sheep producers in the world, and the sheep flock is concentrated in southern and northeast regions. Infectious diseases are responsible for severe economic losses resulting from a decrease in milk and meat production, deaths, and cost of treatment. Among infectious diseases, viral diseases are described chiefly in case reports or retrospective studies. This study aimed to review the main features of viral diseases that affect sheep in Brazil and their current situation in the Brazilian territory. We included eight viral diseases described in Brazil: rabies, bluetongue, contagious ecthyma, foot and mouth disease, visna-maedi, enzootic nasal tumor, ovine pulmonary adenocarcinoma, and border disease. We review the etiological, epidemiological, clinical, and pathological findings for each agent and included differential diagnoses, information on recommended diagnostic methods to confirm the disease etiology, and control measures. This study served as quick consultation material for field veterinarians for an accurate diagnosis.
Un discurso legítimo a partir de lo leído y lo vivido: Apuntes sobre un viajero francés en los contornos de América meridional (s. XVII)
Authors: MARTÍNEZ Carolina
Published: December 2022

Resumen Las descripciones del territorio americano plasmadas por el joven ingeniero François Froger en su Relation d’un voyage fait en 1695, 1696 et 1697 aux côtes d’Afrique, détroit de Magellan, Brésil, Cayenne et isles Antilles, par une escadre des vaisseaux du roy, commandée par M. De Gennes (1698), constituyen un valioso testimonio de sus observaciones sobre el terreno pero también de la influencia ejercida por relatos de viaje anteriores a la región. En principio, revelan cómo a fines del siglo XVII la navegación por las costas de América meridional y el Caribe se tradujo en una política de expansión concreta por parte de Francia. A su vez, evidencian la multiplicidad de representaciones establecidas en torno a un espacio históricamente constituido y, a la vez, en constante transformación. Con énfasis en el estatus epistemológico del texto y su contexto de producción, el artículo examina los procesos de adaptación, traducción y apropiación a partir de los cuales Froger articula un conjunto de saberes (geográficos, etnográficos, etc.) sobre las zonas visitadas. En este sentido, el artículo indaga los recursos retóricos y visuales utilizados por el ingeniero francés así como por su editor para validar el relato ante sus lectores y legitimarse como viajero erudito.
Remarks on Nehemiah and the Idea of “Overtaxation” in Persian Yehud
Authors: ARAUJO Matheus TREUK MEDEIROS DE
Published: December 2022

Abstract This article aims at providing a brief overview of the historiographic writings on Achaemenid taxation, showing how the thesis of overtaxation influenced our understanding of Neh. 5 and Persian Yehud in the 5th century BCE. It describes how it was once widely accepted that overtaxation led to social and economic instability in many peripheral areas of the Achaemenid Empire, including Yehud. According to traditional scholarship, the narrative of Neh. 5 described how the local governor acted to mitigate this crisis by granting temporary tax and debt relief to small farmers. The author then moves to discuss how recent scholars questioned that long-established view, highlighting the biblical source’s rhetorical nature and the logical inconsistencies of the economic explanations used to describe this putative crisis. Finally, this article faces the question of a supposed economic calamity arising in Yehud under Persian hegemony and provides some clues to reevaluate the biblical narrative, particularly in light of recent studies concerning the Persian Empire’s economy and taxation. It supports to some extent the reading of Neh. 5 in an Achaemenid historical context.
“Arrumados como pilhas de charque em porão de navio”: O corpo dos encarcerados como fonte de uma narrativa humanitária no Brasil imperial
Authors: CESAR Tiago da Silva
Published: December 2022

Resumo Propõe-se neste artigo analisar a produção de uma narrativa humanitária acerca das mazelas ou misérias carcerárias e humanas ao longo do período imperial (1825-1889). Utilizar-se-á, para isso, o discurso fabricado por ministros da Justiça (1825-1855), presidentes de província (1855-1889), comissões municipais e provinciais, além de crônicas e denúncias jornalísticas (1885-1886). Tais textos não são meros reflexos de uma realidade social, ou, apenas, resultados de usos políticos: eles também atuaram como motores e amplificadores de sentimentos de empatia e comiseração que poderiam auxiliar na tomada de decisões favoráveis a reformas ou melhorias (paliativas ou não) da vida atrás das grades. É importante precisar, quanto aos relatórios provinciais, que se trabalhará com os exarados para o Rio Grande do Sul e as demais fontes sobre a situação prisional porto-alegrense. Serão contemplados, assim, três níveis: nacional, regional e local. O argumento principal é o de que tais relatos em prol da humanidade e da civilização, em que se expressavam juízos de valor, apreciações, gestos de piedade e sentimentos de benevolência, acabavam alimentando uma “política da piedade” indispensável para o avanço (não linear) do “fluxo das sensibilidades penais”.
Revisiting Cold War Concepts and Interpretations: The State of the Art Among the Echoes of a New Cold War
Authors: SÁENZ ROTKO José Manuel , SANZ DÍAZ Carlos
Published: December 2022

Abstract In face of the growing systemic conflict between the West and China and the sudden escalation of tensions with Russia in the wake of the invasion of Ukraine, the concept of the Cold War reappears in recent years as a reference category. Terefore, the purpose of this article is to present an exhaustive and up-to-date review of the historiographical state of the art in relation to the concept, interpretations, physical and mental spaces and defining systemic structures of the world order between 1947 and 1991. Classic references are included, as well as the most recent, innovative and ground-breaking contributions to the historiography of the Cold War, which since 1991 has undergone a profound makeover, due to the broadening of interpretative categories and the multiplication of historiographical sources. Only by identifying what the Cold War really was will it be possible to construct valid comparative analyses, highlight lines of continuity, describe new variables and, ultimately, draw interpretative frameworks that allow us to understand a potential new cold war in light of the systemic confrontation during the second half of the twentieth century.

ABSTRACT Objective: To evaluate medial joint space in affected and normal contralateral hips in patients with Legg-Calvé-Perthes disease (LCPD). Methods: To compare joint space, femoral head extrusion (FHE), medial space coefficient (MSC) of the hip, and femoral head width (FHW) in affected and normal hips, using 127 radiographs of patients with unilateral LCPD and considering age groups under and over six years old as well as their disease stage. Results: No statistically significant differences were observed regarding MSC between normal and affected hips regardless of disease staging. However, medial joint distance was significantly greater in affected hips than in normal hips. In the necrosis and fragmentation phase, distance from medial space in affected hips was significantly greater than in contralateral normal hips. Comparing only affected hips, MSC and FHW showed statistically significant differences and the group > 6 yo presented higher values. Among normal hips, the group < 6 yo presented a statistically significant difference considering the MSC and FHW. Conclusions: No statistically significant difference was found between the medial joint space of affected and normal hips, except for early stages of the disease (necrosis and fragmentation). The isolated use of radiographic study is insufficient in LCPD and the lack of complementation with other exams, such as magnetic resonance, can delay diagnosis of and onset of treatment for the disease.

ABSTRACT Most epidemiological studies do not exclusively address fractures treated surgically but include those with conservative treatment. In Brazil, few epidemiological studies address fractures prevalence undergoing surgical treatment. Objective: To assess the prevalence, demographics, and associated injuries of surgically treated humeral shaft fractures. Methods: A retrospective study between 2009 and 2019 with patients undergoing osteosynthesis of humeral shaft fracture. Categorical variables were assessed using Fisher’s chi-square or exact test, and non-categorical variables were assessed using the unpaired t-test. A significance level of 5% was adopted. Results: A total of 115 patients were evaluated. Mean age was 37.9 ± 15.6 years, with a male predominance (66.9%) due to car accidents. The most prevalent fracture type was 12 A3. Open fracture prevalence was 11.3%. Radial nerve damage prevalence was 33% and low-energy trauma was twice as likely. Conclusion: Surgically treated humeral shaft fractures were more prevalent in men, young, and related to high-energy trauma, with a transverse line pattern. Fractures secondary to low-energy trauma had a greater association with radial nerve injury. Level of Evidence III, Epidemiological, Retrospective Study.

ABSTRACT Introduction A tennis match may last up to four hours with long intervals between moves of medium to high exercise intensity for 10 minutes and aerobic characteristic that requires specific sources of energy. Inappropriate diets can negatively impact sports performance and delay the recovery phase. Fortified wheat germ protein powder has the supplementation characteristics required in aerobic activities, although there are no practical studies on its impacts on the work performance of female tennis athletes. Objective Explore the influence of two weeks of training in a warm environment combined with nutritional intervention on the performance of female tennis players. Methods It was observed by testing the immunological indices of elite female tennis players while training their changes and their effects on nutritional intervention. Results The increase in serum CK activity was closely related to the amount of exercise. Many studies have shown that serum CK activity increased significantly after strenuous exercise, and the serum CK value of subjects in the test group was significantly lower than that of the control group, showing better adaptability to exercise. Compared with before the nutritional intervention, the athletes’ weight decreased slightly, and the body fat percentage decreased significantly after the nutritional intervention. Compared with before nutritional intervention, sugar and salt supplements in athletes were significantly increased (P<0.05). Sweating rate, hydration rate, and hydration/sudden rate were also significantly increased (P<0.05). Conclusion Strengthening wheat germ protein supplementation may improve the nutritional albumin level in female tennis players, manifested in blood levels and immune function performance.

Authors: Wang Dong
Published: December 2022

ABSTRACT Introduction The biathlon is a snow sport that combines cross-country skiing and shooting, originating in Scandinavia. It requires athletes to not only have the ability to glide quickly over long distances but also to have the ability to shoot quickly and accurately. There is little research on biathlon characteristics and analysis of influencing factors and training strategies in China. Objective This study analyzes modern biathlon athletes’ specific explosive power, endurance and training effects at the Winter Olympics. Methods Twenty biathlon athletes were selected as research volunteers. Physiological and biochemical indicators of the athletes were experimentally tested after training. Results There was a correlation between maximum speed and the height of the athletes’ double stand test (SD) (p < 0.05). The heavier athletes skied relatively faster. However, the excessive body fat rate is not conducive to maintaining high-intensity skiing in the long term. The athletes’ VO2max was closely related to their skiing performance and shot hit percentage (p < 0.05). Conclusion Maintaining gun ski training can positively improve the competitive level of world-class biathletes. The athlete's muscles have a solid ability to generate high mechanical power in a short time. It is beneficial to take advantage of a favorable position after the start of the competition.

Authors: Yang Yingwei
Published: December 2022

ABSTRACT Introduction: Recent studies have shown that altitude training can significantly improve hemoglobin content in athletes. This allows for greater oxygen transport to the muscles and, consequently, greater load capacity during training. However, there is no confirmed evidence of athlete-specific training in martial arts. Objective: Explore the load capacity and ability changes caused by high altitude training in athletes. Methods: The research selected ten high-level martial arts athletes as volunteers to compare the functional changes caused by high-altitude training. Physical and functional data were collected before the beginning of the experiment and at its conclusion after three weeks. Results: Measured abilities were significantly improved after 11 days of altitude physical training. After 21 days of altitude training, these abilities improved significantly. The urea nitrogen and creatine kinase values increased rapidly with increasing load intensity in the first stage, peaked in the second stage, and decreased in the third stage. Conclusion: Training in the low-pressure hypoxic environment at high altitude, using dual stimulation of hypoxia and exercise to make the athletes stress response, can stimulate the physical potential to achieve a range of physiological abilities to improve the body’s resistance to hypoxia.

ABSTRACT Introduction: Martial arts training focuses on science, methodology, and practice. Martial arts are a symbol of physical fitness. The academic analysis of the influence of martial arts training on children’s physical health is of great importance for promoting traditional Chinese culture. It can enrich sports intervention programs to improve children’s physical health. Objective: Analyze the effect of sensory quality training on martial arts balance training in children. Methods: Children aged 8 to 12 years were selected as research subjects. After repeated deliberations, a children’s martial arts set was designed and implemented. The pilot project analyzes the importance of sensory quality in the essential stage of children’s martial arts training. Results: After the experiment, there was a significant difference in balance quality in the experimental group (p<0.01). After the experiment, the difference in balance sense between the experimental and control groups was significant (p<0.01). Conclusion: In the basic training phase of children’s martial arts, coaches should require athletes to master basic martial arts skills more comprehensively. All movement combinations in martial arts require comprehensive physical fitness and balance sensitivity, including speed, flexibility, and coordination.

Published: December 2022

ABSTRACT Introduction The outcome of basketball games is based on scoring, and basketball rules are discussed from a qualitative point of view. The three-point basket is the key to the game's success; improving this shot's percentage will ensure success. Objective Explore the key elements of a successful three-point shot, discussing its effective improvements. Methods This paper randomly selects 26 students from a particular basketball class as volunteers for the research. Before starting the experiment, the subjects were divided into control and experimental groups; they were grouped according to their test scores. Four data of three-point shot rate, jump shot, and shot after dribbling are analyzed according to the grouping of players. The data were statistically treated for better appreciation of the results. Results Although the throws improved in both groups, the improvement was insignificant (P>0.05). After nine weeks of exercise, the success rate of three-point baskets in both the experimental and control groups improved. The improvement in the three-point basket was the greatest in the experimental group (P<0.05). Conclusion Functional strength training can significantly improve the rate of long-range 3-point baskets in basketball players.

Authors: Feng Chen
Published: December 2022

ABSTRACT Introduction: There is a correlation between competition performance with a concentration in competitive archery athletes. It is an essential theme in academia to improve the performance of archers, the belief that this goal can be achieved by increasing their concentration. Studies on concentration and relaxation in archery training have shown effective indicators to evaluate training intensity and athlete cognition, but there is still no scientific consensus. Objective: This study aims to analyze the impact of concentration on traditional archery and athlete performance during competition. Methods: Twenty traditional archers were selected as research volunteers. They underwent a battery of biometric tests, including an EEG system to perform group tests. A chi-square test was performed on concentration and relaxation data. The results were analyzed according to the influence of the above two factors on the athletes’ performance. In parallel, this paper analyzed the relationship between the degree of relaxation and the archers’ performance. Results: There was a positive correlation between concentration and performance. More focused athletes perform better. The data were statistically significant (P<0.05). There is a positive correlation between relaxation and performance. The data were statistically significant (P<0.05). Conclusion: The results of this article provide evidence that both concentration and relaxation can help improve archer performance.

Do político ao econômico: aportes da teoria dos sistemas a uma crítica do neoliberalismo

Published: December 2022

Resumo Este artigo propõe uma leitura cruzada entre a teoria dos sistemas de Niklas Luhmann e os estudos sobre governamentalidade neoliberal inspirados por Michel Foucault. Em vez de sugerir um déficit na autopoiese dos sistemas, o texto avança a hipótese de que o neoliberalismo se expressa na forma de uma colonização dos mecanismos operacionais dos sistemas funcionais: o direito e a política, especialmente, são tomados de uma racionalidade econômica específica que passa a reger suas formas de autorreferência (reflexividade e reflexão) e heterorreferência (observação de segundo grau, sobretudo pela ciência). Por essa específica colonização da autopoiese dos sistemas funcionais, a racionalidade neoliberal paradoxalmente mantém a diferenciação funcional mas restringe seus pressupostos: um grau de inclusão social e desintegração sistêmica que permita manter a distinção entre os códigos e programas econômicos, políticos e jurídicos.

Abstract Objective: to investigate the effect of using different agents (topical hyaluronidase, photobiomodulation, and the association of photobiomodulation with topical hyaluronidase) in preventing the formation of lesions caused by doxorubicin extravasation, as well as in the reduction of lesions formed by extravasation of this drug. Method: a quasi-experimental study conducted with 60 Wistar rats, randomized into four groups with 15 animals each. Group 1 (Control); Group 2 (Hyaluronidase); Group 3 (Photobiomodulation); and Group 4 (Hyaluronidase + Photobiomodulation). A wound was induced by applying 1 mg of doxorubicin to the subcutaneous tissue of the back of the animals. The concentration of topical hyaluronidase was 65 turbidity units/g and the energy employed was 1 joule of 100 mW red laser per square centimeter. With macroscopic evaluation every two days for 28 days, the following variables were observed: skin integrity, presence of blisters, hyperemia, exudate, bleeding, edema, crust, peeling and granulation tissue. Results: the animals from the groups subjected to photobiomodulation obtained better results in the assessment of the following variables: bleeding, hyperemia, exudate, intact skin and edema. Conclusion: it was evidenced that the association of photobiomodulation with topical hyaluronidase was effective in reducing the local effects and assisted in the wound healing process, and that PBM alone was able to prevent appearance of lesions.
