La población de la parroquia de Encarnación (Nueva Galicia) a través de los padrones de 1819 y 1820. Problemas metodológicos
Authors: Torres Franco Carmen Paulina
Published: July 2019

Los padrones constituyen una de las fuentes de información más utilizadas para estudiar el crecimiento de las poblaciones en el pasado. Los historiadores han considerado que su información es fidedigna, pero no se han analizado a profundidad los errores que pudieron cometer los empadronadores, ni se ha reflexionado sobre la magnitud de dichos equívocos y cómo podrían afectar los resultados de las investigaciones históricas en México. El objetivo es describir cuáles fueron las deficiencias en la elaboración de los padrones de 1819 y 1820 en la parroquia de Encarnación, con la intención de cuestionar su uso, haciendo énfasis en la necesidad de una crítica de fuentes mayor y en las ventajas de los análisis nominativos en las investigaciones de historia demográfica. Para realizar la investigación se hizo una contrastación de fuentes en tres niveles: padrones (1819 y 1820); los registros de bautizo, matrimonio y entierro; y reconstrucción de familias. La comparación mostró deficiencias (tanto en aspectos cuantitativos como cualitativos) en la elaboración de los padrones de la parroquia de Encarnación, lo que llevó a cuestionar su uso como fuente idónea para comprender el crecimiento de dicho lugar.
Memorias y violencias en Medellín
Authors: Martin Gerard
Published: July 2019

Este ensayo reflexiona sobre la oportunidad y las posibles maneras de ampliar el trabajo de memoria histórica de las víctimas del conflicto armado en Medellín, con investigaciones sobre las víctimas de otras violencias en la ciudad, en particular las del crimen organizado y mafioso, fuertemente relacionado con el tráfico de cocaína. El autor argumenta que sin incluir aquellas otras víctimas en los trabajos de memoria histórica es imposible comprehender la tragedia de Medellín en su totalidad. El autor sugiere varias maneras de abordar esta tarea de visibilización de aquellas otras víctimas.

Published: July 2019

Dentro de los tubérculos andinos de mayor importancia, después de la papa, se encuentra la ibia (Oxalis tuberosa Mol.) ya que constituye un alimento básico para las comunidades andinas. Boyacá es uno de los departamentos de Colombia, en donde todavía existe la tradición de cultivar y consumir tubérculos andinos como los cubios, ullucus y rubas o ibias, sin embargo están amanezados por la erosión genética. No existen estudios sobre estos recursos fitogenéticos en Boyacá, por lo cual el objetivo de esta investigación fue colectar y caracterizar morfológica y molecularmente materiales de ibias en este departamento. El análisis morfológico mostro que las características más discriminantes fueron: color de los tallos aéreos, pigmentación de las axilas, color del follaje, color de la flor, color del pedúnculo y pedicelo, color predominante de la superficie del tubérculo, color secundario de la superficie del tubérculo, color predominante y secundario de la pulpa, distribución del color secundario de la pulpa y forma de los tubérculos. El análisis de similitud diferenció a los materiales en dos grandes grupos, de acuerdo principalmente a características morfológicas como el color y hábito de floración. El valor de hetorocigosidad promedio para la población total fue de 0.39 el cual se considera alto al compararse con otros estudios de diversidad genética en ibias. El análisis de varianza molecular (AMOVA) y el Fst (coeficiente de diferenciación genética) muestran que existe una alta variabilidad genética entre los materiales de ibias evaluados la cual debe ser conservada y aprovechada dentro de futuros programas de mejoramiento.

TRANSFORMATION OF STATE SECURITY AGENCIES IN THE PERIOD OF THE KHRUSHCHEV’S THAW
Authors: Lushin Aleksandr I. , Kalinin Ivan V.
Published: July 2019

Introduction. The epoch of Khrushchev’s “thaw” is a turning point in the history of the development of state security agencies. There is a break in the ideological connection between Cheka agency’s methods of work and the newly formed State Security Committee under the USSR Council of Ministers, a rethinking of the structure, goals and objectives of the department in accordance with the new policy of the ruling authorities. Research methods. In order to study the reform trends in the state security bodies of 1953–1964, in the article the method of historicism was used. It allows to consider the institute of state security bodies in the context of the definitely historical conditions of its existence. Besides the elements of the comparative historical method was used for creating a general idea of the tasks and goals of the department from the beginning of its existence in the RSFSR and until the end of period. Results and discussion. The analysis of publicly available sources of scientific literature has allowed to delineate the boundaries of modernization processes in the state security agencies of the Khrushchev “thaw” period. The actual transition of the heir to the VChK – OGPU – NKVD – NKGB – MGB from subordination of the state to the party power determined the further development of the KGB. Entirely subordinate to the party apparatus, the department was transformed depending on the interests of the political bureaucracy in power. However, the absence of a specific policy and the obvious distrust of N. S. Khrushchev to the state security authorities led to mixed results in regarding the effectiveness of the KGB, designed to ensure the protection of the country. The negative consequences included “the birth trauma” of the KGB after the 20th Congress of the CPSU, denouncing the violation of legality by the past KGB, weakening the moral and psychological climate inside the system and turning the Committee, designed to protect the state and its citizens from internal and external threats, into a party appendage with the inviolability of party employees, which led to a decrease in the rule of law. The positive results of the transformation of the state security bodies consisted in partial liberalization of the established system, softening the methods of the KGB, reorienting to protect the state from external enemies, creating the legal basis of the department’s activities and promoting its positive image.

Published: July 2019

Introduction. The problem of the psychological characteristics of the identity of a woman is discussed. The modern woman plays a significant role in the sociopolitical, economic, and social life of the country, makes a significant contribution to the upbringing of children in the family, and pays considerable attention to building its life trajectory and professional career. Cognitive activity, ambitiousness, autonomy, independence, striving for achievements – these and other qualities, in the patriarchal environment unacceptable for women, are becoming quite common today in the behavioral manifestations of women. The social roles of women today are undergoing significant changes, therefore issues related to women’s identity have recently been among the most discussed in society and science. The basic mechanisms for the formation of women’s identity within the framework of gender socialization are being comprehended. Materials and Methods. The cultural-historical and personal-activity approaches are considered as the theoretical and methodological strategy of the research, the female sample is the object of the research. The psychological features of the identity of modern women of different ages and the status of mainly small provincial cities of Russia are highlighted. Results. The results of an empirical study of a female sample of identity features of women living in the province are proposed. Discussion and Conclusion. The proposed provisions and conclusions create prerequisites for further study and understanding of the phenomenon of female identity in the methodological, substantive, procedural, and organizational plans.

Introduction. The development of domestic music vocational education is currently influenced by various factors: political, economic, demographic, etc. One of the socio-economic factors can be attributed to the processes of urbanization. Studying and using the historical experience of forming a system of musical vocational education in Russia in the context of urbanization can contribute to the development of an effective state strategy for the development of a training system for a musician-practitioner at the present stage. Materials and Methods. The study made an attempt to provide more complete coverage of the work of domestic scientists on the history of domestic urbanization and the history of domestic musical vocational education. In the study and synthesis of scientific sources used methods of theoretical interdisciplinary analysis and synthesis, methods of comparative historiographical analysis. The study used comparative historical, historical and typological methods, as well as general scientific methods of system and structural-functional analysis. Results. The paper presents evidence that as a result of administrative and territorial reforms, an increase in population, the development of education, culture and education, there is a need for qualified specialists (including a music profile). Conclusion. The study showed that as a result of a legitimate public request for professional musicians, educators and performing musicians, and thanks to the activities of the Imperial Russian Musical Society in the second half of the XIX century, a network of musical educational institutions (music classes, music colleges, conservatories) was formed vocational education.

Published: July 2019

Abstract The Myrtaceae family has representatives spread worldwide, and Jabuticaba tree is an important species native to Brazil, which is grown not only in the backyards and domestic orchards, but also in commercial orchards, landscaping projects and in several tropical and subtropical countries. The propagation of this species in a sexual form or by seeds is simple and efficient, being able to reach 100%. However, long juvenile phase and genetic segregation have led to the search for methods that allow the propagation of selected trees and guarantee through their standardized and productive clones, fruit quality and fruiting precocity. Protocols for asexual propagation are still scarce, but they show efficient methods, making possible the commercial use and valorization of this Brazilian fruit tree. Grafting methods have proven to be efficient in more than 70% of cases. Herbaceous cutting in Jabuticaba trees shows rooting around 10%. Air layering shows rooting rates above 80%. Other methods considered for domestic use have shown satisfactory results in the formation of young saplings through woody cuttings. New studies on micropropagation and better control of herbaceous stem cutting processes could stimulate and economically increase the propagation of this fruit tree for commercial crops to produce fruits for fresh consumption or processing. Air layering and grafting are the most currently indicated methods for propagation of jabuticaba tree. This review paper shows the results of other papers and their protocols for obtaining jabuticaba tree seedlings and clonal plants.

Análise moral e ética no cuidado com a saúde de adolescentes cabo-verdianos e brasileiros referente ao consumo de cigarros, álcool, drogas e anabolizantes
Authors: Marinho Julio Cesar Bresolin , Silva João Alberto da
Published: July 2019

Resumo: A saúde dos adolescentes tem sido pauta de discussões visto que esses sujeitos configuram-se como vulneráveis. Nesse trabalho tratamos da temática do consumo de cigarros, álcool/drogas e anabolizantes e procuramos analisar suas percepções morais e éticas sobre a questão. A pesquisa é qualitativa e o método utilizado foi o Estudo de Caso. Foram realizados cinco grupos focais tendo como instrumentos de coleta de dados os dilemas morais. Participaram 45 adolescentes de Cabo-Verde e do Brasil. Para não utilizar drogas evidencia-se que é importante a construção das representações de si com valor positivo, mas por vezes os adolescentes se vêem coagidos por pressão do grupo. Em relação à utilização de anabolizantes, alegaram que é incorreto, faz mal e deve-se pensar na saúde. Por outro lado, acreditam que os adolescentes acabam por utilizar, pois pensam apenas no hoje e buscam a perfeição.

Resumo: Analisamos neste artigo o potencial formativo da técnica de grupos focais na constituição de educadores ambientais, a partir de três diferentes pesquisas pautadas na perspectiva dialógica crítica. Utilizamos a hermenêutica enquanto modo de interpretação do conjunto dos dados e percebemos, enquanto resultado, que os grupos focais não são permanentes, ao contrário, possibilitam múltiplas construções partilhadas de sentidos, podendo gerar mudanças de posturas pessoais diante da aquisição de novas informações, reflexões e argumentos. Destacamos algumas habilidades de educadoras/es ambientais, tais como a mediação, a reflexão, a criticidade, o compromisso com a transformação, a alteridade e a flexibilidade que podem ser alcançados com o grupo focal. Dessa forma, observamos o grande potencial formativo dessa técnica quando conduzida de maneira dialógica e participativa.
Cultura política, desempenho escolar e a Educação em Ciências: um estudo empírico à luz de Pierre Bourdieu
Authors: Nascimento Matheus Monteiro , Lima Nathan Willig , Cavalcanti Cláudio José de Holanda , Ostermann Fernanda
Published: July 2019

Resumo: Discussões sobre política e economia não estão presentes nas aulas de Ciências do Ensino Médio, restringindo-se em geral ao contexto das disciplinas das Ciências Humanas. Isso gera, por vezes, um desinteresse e uma alienação dos jovens sobre temas políticos, econômicos e sociais. Neste trabalho pretendemos chamar a atenção para a falta de interesse pela política por parte dos alunos e que esta pode estar associada ao seu desempenho escolar, especialmente nos estudantes oriundos das classes populares. Para tanto, utilizamos como dados empíricos as respostas dadas a um questionário por candidatos ao maior exame de larga escala do Brasil, o Exame Nacional do Ensino Médio (ENEM). Na sequência, nos apropriamos do trabalho teórico de Pierre Bourdieu para tentar justificar a relação existente entre política, economia e os resultados escolares. Além disso, discutimos de que forma o Ensino de Ciências pode contribuir para a diminuição da brecha entre cultura política e cultura escolar.

Resumo: Este artículo reflexiona sobre la interactividad y la experiencia de los adolescentes en museos de ciencias, a través de un estudio exploratorio y cualitativo realizado en el Centro Interactivo de Ciencia y Tecnología Abremate (Argentina). El corpus recoge el registro audiovisual de las visitas realizadas por cinco grupos de estudiantes de 14 a 17 años de escuelas públicas del conurbano bonaerense. Los datos recolectados se codificaron con una herramienta orientada a comprender procesos de aprendizaje en museos de ciencias de América Latina. El análisis indica que la interactividad está presente, principalmente, en situaciones en las que los jóvenes interactúan en simultáneo con la exhibición y entre ellos, mientras conversan sobre la manipulación de los artefactos. También se observa que hay condiciones iniciales para promover el aprendizaje de actividades que enseñen a pensar y ejercitar emociones sobre la inteligibilidad del mundo.

Published: July 2019

Resumo: Baseada na teoria dos códigos de Basil Bernstein, Andréia de Oliveira propôs o conceito de Tensão nos Discursos para designar as descontinuidades entre os diferentes discursos presentes na prática educacional, marcadas pelas contradições, rupturas e dilemas gerados pelos espaços que separam as categorias de discursos especializados. Neste artigo analisamos as tensões representacionais manifestadas nos discursos dos alunos quando realizavam atividades experimentais em um laboratório didático de Física. Essas tensões se caracterizam por mostrar as contradições, rupturas, dilemas, conflitos e incertezas quando os dados provenientes das atividades experimentais são confrontados com os conceitos apresentados nas aulas teóricas, evidenciando um isolamento no discurso interno à Física. Verificamos que os estudantes manifestaram essas tensões nos momentos em que representaram as medidas com suas incertezas, transformaram as unidades de medidas e suas incertezas e ao registrarem o número de casas decimais e de algarismos significativos das medidas e de suas incertezas.

Published: July 2019

ABSTRACT Objective To determine the influence of combat sports on bone mass. Methods A systematic review was performed according to the PRISMA method, with searches in the Pubmed, Bireme, Embase and Web of Science databases covering the period 1900 to 2015, using the keywords “martial arts”, “fight”, “combat”, “karate”, “kung fu”, “tae kwon do”, “judo”, “aikido”, “bone mass”, “bone health”, “bone tissue”, “bone density”, and “bone mineral contents”. The articles were searched for and retrieved electronically and manually, by two independent reviewers. Results Seventy-nine articles were identified, of which 25 were duplicates, leaving 54 for reading and evaluation of the titles; next, articles about diseases such as bone and/or orthopedic injuries, maxillofacial, surgeries, fractures, osteoporosis and osteopenia in women, prevention of falls, and physical fitness were excluded, leaving 15 articles. Of the articles selected and retrieved in full, all were published between 2002 and 2015. One article was a case control study; two were longitudinal studies, two were randomized studies; and 10 were cross-sectional studies. A total of 1368 children, adolescents, adults and elderly subjects were involved in combat sports and had bone evaluation by imaging. Factors such as calorie intake, calcium and/or vitamin D, intensity and volume of the exercise, hormonal aspects as bone markers, and characteristics of menopause are not conclusive in relation to bone mass, and further studies are needed. Conclusion The practice of combat sports shows a significant improvement in bone mass at all ages. Level of Evidence III, Therapeutic study – Investigation of treatment results.

ABSTRACT Introduction The structural and mechanical adaptations of the right ventricular (RV) myocytes in response to hypertension associated with low-intensity endurance training (LIET) have not been studied in experimental models. Objective To determine the effects of LIET on the structural and mechanical properties of RV myocytes in spontaneously hypertensive rats (SHRs). Methods Male SHRs and normotensive Wistar rats (age: 16 weeks) were allocated to groups (n=7): WIS (Wistar Controls); SHR-C (SHR Controls) and SHR-T (SHR Trained; 60 min/day, 50-60% of maximal exercise capacity, 5 days/week for 8 weeks). Systolic arterial pressure (SAP), isolated RV myocyte dimensions, contractility, intracellular Ca2+ transient ([Ca2+]i), and ventricular Ca2+ regulatory proteins were measured. The statistical analysis was performed by one-way ANOVA followed by the Tukey post hoc test (α=5%). Results LIET reduced the SAP in SHR animals (SHR-C, 164 ± 2 mmHg vs. SHR-T, 152 ± 4 mmHg; P<0.05). Hypertension increased cell length (WIS, 156.8 ± 2.7 µm; SHR-C, 166.6 ± 3.1 µm; P<0.05) but did not affect cell width or volume (P>0.05). LIET did not change the cell dimensions in the SHR-T. Neither hypertension nor LIET affected myocyte contractility or the expression of Ca2+ regulatory proteins in the RV of the SHR-C and SHR-T groups. Hypertension did not affect the amplitude of the [Ca2+]i transient or the time to half resting level (P>0.05), but increased the time to peak (WIS, 58 ± 1 ms vs. SHR-C, 79 ± 2 ms; P<0.05). LIET increased the amplitude of the [Ca2+]i transient (WIS, 2.28 ± 0.07 F/F0 and SHR-C, 2.48 ± 0.08 F/F0 vs. SHR-T, 2.87 ± 0.08 F/F0 P<0.05), but did not alter the times to peak or to half resting level. Conclusion LIET had no effect on the structural and mechanical properties of RV myocytes in the SHRs, although it increased the amplitude of the [Ca2+]i transient and reduced the SAP.

SOCCER CLEATS WITH BLADE-SHAPED STUDS AND MECHANICAL OVERLOAD IN SOCCER: A SYSTEMATIC REVIEW
Authors: Cardoso Filho Carlos Alberto , Claudino João Gustavo , Lima Wilson Pereira , Amadio Alberto Carlos , Serrão Júlio Cerca
Published: July 2019

ABSTRACT Soccer cleats with blade-shaped studs promote greater traction on the pitch and can be beneficial for soccer performance. On the other hand, movements with rapid changes of direction, associated with the high traction of soccer cleats, can increase overload and risk of injuries. Given the lack of consensus on the effects of these cleats on mechanical overload during specific soccer movements, the aim of this systematic review was to determine the effects of wearing cleats with bladed studs on mechanical overload in soccer. A search was conducted in the PubMed, Scopus, and Web of Science electronic databases between October and November 2017. Non-original articles were excluded, as were those not related to soccer or cleats, and those not written in English. Eight articles were included that tested the effects of bladed studs on overload and that used biomechanical tests. The tasks evaluated were: running in a straight line or with changes of direction, and landing of jumps. The resulting joint torque, soil reaction force, electromyography, and plantar pressure were measured. There was no influence of bladed shaped studs on joint torque or on ground reaction force. There was an increase in plantar pressure on the lateral part of the foot in bladed studs compared to Society cleats and running shoes. When compared with round studs, the results were inconclusive for plantar pressure. Round studs, caused greater electromyographic activity in the quadriceps muscles than bladed studs. It was concluded that wearing bladed-stud cleats does not result in greater mechanical overload during running or landing of jumps. Evidence Level I, Systematic Review.

Published: July 2019

ABSTRACT Introduction Some studies suggest that playing tennis brings benefits for the anthropometric and metabolic profile of those who practice it, reducing the risk of mortality more significantly than other sports. In addition, changes in cardiovascular autonomic regulation have been highlighted as a common factor in the development of cardiometabolic disorders. Objective To evaluate and compare hemodynamic parameters and cardiovascular autonomic modulation among former tennis players who still play the sport (ET), adults who play recreational tennis (TR), and adults classified as sedentary (S). Methods Thirty-four men aged between 23 and 45 years participated in the study. They were divided into 3 groups: ET, TR and S. Anthropometric parameters and blood pressure were evaluated and the R-R interval was recorded to quantify the cardiac autonomic modulation at rest. Results Similar values were observed between groups for blood pressure, waist circumference and body mass index. The amount of moderate and vigorous physical activities of the ET group was higher than that of the TR group. The ET presented resting bradycardia associated with increased pulse interval (PI) variance and high-frequency PI, and a reduction in low-frequency PI compared to the other groups studied. Reduced cardiac sympathovagal balance was observed in the ET group (1.7 ± 0.1) and TR group (2.5 ± 0.2) compared to the S group (3.2 ± 0.2); however, this change was exacerbated in the ET group compared to the TR group. Conclusion The results suggest that playing tennis induces beneficial changes in cardiac autonomic modulation that appear to be intensified as the volume of physical activity increases, suggesting that this practice is beneficial in the management of cardiovascular risk.

ABSTRACT Although muscle strength, lean mass and bone mineral content/density (BMC/BMD) are consistently reported as major outcomes of resistance training (RT), there is still no agreement on the RT regimen that is capable of achieving this result in men and women of different ages. This study describes the effects of RT on muscle strength, lean mass and bone mineralization, highlighting the relationships between them and analyzing the effectiveness of the RT protocol. Information searches were conducted in open access online academic libraries, using the BMC/BMD indices combined with muscle strength, body composition, and resistance exercises. The results showed changes in BMC/BMD in 72% of the studies published in the last decade. Among these, 77% recommended loads ≥ 80% 1-RM, 61% involved older individuals (> 60 years) and 61% had planning protocols of between 3 and 5 months (~12-20 weeks). The results also highlight muscle strength as a promising index of variations in BMC/BMD, with a moderate to high level of association (r2>0.5), which are specific for men and women in relation to the body region with best responsiveness. Among the studies published in last decade, about 61% had protocols involving only RT, and of these, 82% observed combined changes in BMC/BMD, body composition and muscle strength. This review therefore concludes that RT is important for improving muscle strength, increasing lean mass (whole-body and regional) and preventing risk factors that could impair the mineral integrity of the bone tissue, in individuals of all ages and sexes.

ABSTRACT Introduction Olympic weightlifting has been adopted as an alternative to plyometric exercise. However, the effects of these exercises in young handball athletes is not known. Objective To compare the effect of Olympic weightlifting training with traditional strength training on jumping, squatting and acceleration performance in young handball athletes. Ten female handball athletes were evaluated. After six weeks of regular training, the athletes underwent eight weeks of training specifically designed for the survey, with equivalence of the total volume of training and differences in the means used. The evaluations were performed after six weeks of regular training (Baseline), after four weeks of traditional strength training and after four weeks of Olympic weightlifting. Vertical Jumps with and without movement of the arms, acceleration of 10 m, 20 m and 30 m, and 1RM in squatting were quantified. Results Increases (p<0.05) were observed in accelerations and squatting in the Olympic weightlifting and in squatting in the traditional strength training. Differences in coordination, time to activation of the gastrocnemius, vastus lateralis, rectus femoris, biceps femoris and gluteus maximus, peak force and power and rate of force development between the jumps and exercises used in the training are hypotheses to be considered for the different responses adaptations found in the jumps. Conclusion The Olympic weightlifting training resulted in an increase in accelerations and strength, but not in vertical jump performance in young handball athletes.

ABSTRACT Ducks, geese and swans are included in the Anatidae family, Anseriformes order. The leading injuries causes to waterfowl are tangling in fishing materials and foreign bodies ingestion. A muscovy duck (Cairina moschata) was referred for treatment at Veterinary Teaching Hospital and a radiographic examination showed the presence of a hook in the coelom. Surgical exposure and incision of the proventriculus was made through left intercostal access and the hook along with a fishing line were gently removed. The animal began to feed voluntarily at the fourth post-operative day and two weeks after the procedure the patient was clinically well and was released to wild. This surgical approach differs in some aspects from the listed techniques in the known literature. It proved to be a viable and appropriate alternative to treat this affection since it did not cause any trans- or post-operative complications and enabled rapid recovery and subsequent patient release.

RESUMO O objetivo do presente estudo foi avaliar o efeito da adição de plasma seminal de garanhões de alta e baixa fertilidade sobre a congelabilidade e a viabilidade de espermatozoides do ejaculado (EJ) e do epidídimo (EP) de garanhões subférteis. Foram utilizados seis garanhões com histórico de subfertilidade. Após coleta, espermatozoides do ejaculado foram divididos em três alíquotas: BotuSêmen® (EJ-CT); plasma seminal de alta qualidade espermática (EJ-PS1); e plasma seminal de baixa qualidade espermática (EJ-PS2). O mesmo protocolo foi realizado com espermatozoides da cauda do epidídimo após orquiectomia (EP-CT; EP-PS1; EP-PS2). Foram realizadas avaliações da cinética espermática pelo CASA e análises de integridade de membrana, acrossoma, fragmentação de DNA, capacitação espermática e peroxidação espermática por citometria de fluxo. Não foram observadas diferenças na cinética espermática entre EJ e EP, logo após a descongelação. Porém, foi observada maior (P<0,05) porcentagem de células com membranas plasmática e acrossomal íntegras nos grupos EP (EP-CT:31,7±7,5b; EP-PS1:35,2±7,0b; EP-PS2:33,9±7,2b) em comparação aos grupos EJ (EJ-CT:15,1±4,9a; EJ-PS1:11,7±4,5a; EJ-PS2:13,1±5,2a). Adicionalmente, foram observadas diferenças no índice de fragmentação de DNA (EJ-CT:2,6±0,6a; EJ-PS1:2,4±0,8a; EJ-PS2:3,0±0,8a; EP-CT:1,4±0,4b; EP-PS1:1,2±0,3b; EP-PS2:1,3±0,2b). Concluiu-se que a adição de 20% de plasma seminal, oriundo de animais férteis ou subférteis, previamente à congelação de espermatozoides epidídimários de animais subférteis não interfere na qualidade espermática.

RESUMO Atualmente o uso de sensores portáteis para mensuração de corpos cetônicos está padronizado e difundido na rotina clínica, contudo estudos em ovinos são escassos. Assim, a presente pesquisa objetivou avaliar a acurácia dos sensores portáteis de uso humano e de uso veterinário para a determinação de beta-hidroxibutirato (BHB) em ovelhas no final da gestação e no pós-parto recente. Foram utilizadas 37 amostras de sangue provenientes de nove ovelhas mestiças Corriedale. A determinação bioquímica de BHB no soro, considerada como o padrão-ouro, foi realizada utilizando-se metodologia enzimática colorimétrica. A média obtida na bioquímica sérica foi de 0,497mmol/L; no sensor de uso humano, a média foi igual a 0,537mmol/L, enquanto no sensor de uso veterinário foi de 0,751mmol/L. Foi verificada alta correlação entre o dosímetro de uso humano e o padrão-ouro (r=0,93, P<0,001). A média do aparelho de uso veterinário diferiu das demais (51%; P<0,05), superestimando os resultados em ovelhas. As medições obtidas no aparelho veterinário também apresentaram menor precisão e veracidade. Concluiu-se que o sensor portátil de uso humano é mais acurado e mais preciso no diagnóstico precoce de toxemia da gestação em ovelhas.

ABSTRACT The objective of work was to study the productive profile of perennial peanut in a rotational stocking environment under different criteria. The treatments corresponded to pre-grazing height of 14 and 18cm or 95% of light interception (LI) distributed in a completely randomized design. The studied variables were forage mass, percentage of structural components, forage mass and the structural components in the lower and upper canopy strata. The entrance criterion of 18cm in height, despite having higher forage mass, presented lower percentage of leaves and higher percentage of stems and forage losses. The criteria of 14cm and 95% light interception presented similar production between them and the highest rate of forage accumulation. In all criteria, in the upper strata of pasture a higher percentage of leaves were found. The criteria of 95% LI and 14cm in height presented the best productive performances. The entry criterion of 18cm presented a higher mass of pre-grazing forage with lower percentage of dead material, but with higher forage losses, resulting from senescent leaves. Due to changes in the structural components, as grazing cycles increase, the interception of 95% of the incident light by the perennial peanut occurs at lower heights.

ABSTRACT The objective of this study was to evaluate the effect of the partial replacement of elephant grass silage with babassu (Orbignya speciosa) on the performance, intake, digestibility, and carcass weight gain of sheep. Fifty-four castrated male lambs (19.08±2.76kg) were distributed in a completely randomized design and administered one of the following treatments: 0.0, 12.5, 25.0, 37.5 or 50% dry matter (%DM) replacement of elephant grass silage with babassu cake. No difference (P> 0.05) was observed in the dry matter, crude protein, and neutral detergent fiber intake, but the ether extract intake increased (P< 0.05). The digestibility of the dry matter, neutral detergent fiber, and total digestible nutrients were unaffected. The crude protein digestibility decreased (P< 0.05), and the ether extract digestibility increased with the replacement of the elephant grass. There were no changes in mean daily weight gain and carcass weight gain. In the carcasses, a linear increase was observed in the proportion of the ether extract, and the crude protein decreased. The replacement of the silage with the babassu cake by up to 50% did not change the performance of sheep, however it led to an increase in fat deposit in the carcass.

RESUMO Reticulose pagetoide é a expressão utilizada para uma das mais raras formas de linfoma descritas em cães. Trata-se de um distúrbio linfoproliferativo cutâneo que emerge de linfócitos T intraepidérmicos. Descreve-se aqui um caso de reticulose pagetoide com apresentação localizada, muito semelhante à doença de Woringer-Kolopp dos humanos, que acometeu um cão, Boxer, fêmea de 10 anos de idade. O paciente foi atendido devido ao aparecimento de um nódulo na região nasolabial, com evolução clínica de cerca de 30 dias. Histologicamente o nódulo era composto por uma proliferação linfoide intraepidérmica e anexal. Os linfócitos neoplásicos, células T confirmadas por meio da imunomarcação positiva para CD3 e negativa para CD79, eram grandes células redondas e monomórficas. Apesar de rara, a reticulose pagetoide é um distúrbio linfoproliferativo de fácil suspeita com base apenas na morfologia celular. Esse neoplasma deverá ser lembrado sempre que um padrão linfoide intraepidérmico estiver presente.

ABSTRACT English Thoroughbred horses, are widespread in Mexico and due to the lack of data on their exercise physiology, it is important to conduct exercise tests in order to obtain information the effects of exercise on more essential cations/anions in blood serum, as these horses are submitted to constant efforts. The study was carried out with 150 blood samples of English Thoroughbred horses clinically healthy. The blood sample collection was performed during three periods: 1) rest, 2) 30min after exercise (speed race of 12km/h for 30min with no rest) and 3) 60min after exercise. Mean values were calculated for cations (sodium and potassium) and anions (chloride and bicarbonate). The resulting data set was analyzed using Gaussian distribution and descriptive statistics. Confidence intervals of 95% were established. The linear relationships between ions were quantified, and an analysis of variance was performed to compare the mean values between groups. The concentrations of the described analytes are consistent with values reported by international literature. The comparison between groups, revealed that during exercise, sodium ion did not show changes 30min after exercise and increase 60min after. Potassium ion showed increase 30min after exercise and decrease 60min after. Chloride ion showed a decrease 30min after exercise, to recover gradually 60min after. Meanwhile, bicarbonate ion showed increase 30min after exercise, decreasing slightly in the final stage. Negative correlation between bicarbonate ion and chloride ion were determined. It was concluded that exercise tests are useful for the determination of acid-base balance and osmotic balance, and their main role is to evaluate the athletic ability of horses.Considering that chloride ion excretion and metabolic adjustments of potassium ion and bicarbonate ion are superior to water loss, compared to the normal osmolarity of blood serum. The results found can be used to structure an adequate replacement program of electrolytes lost in sweat.
