Association of testicular echogenicity, scrotal circumference, testicular volume and testosterone concentration in buffaloes. [Associação entre a ecogenicidade, circunferência escrotal, volume testicular e concentração de testosterona em búfalos.] Revista Brasileira de Medicina Veterinária, 38(4):334-340, 2016. Programa de Pós-Graduação em Ciencia Animal, Universidade Federal do Pará, Rua Augusto Corrêa 1, Campus Universitário do Guamá, Belém, PA 66075-110, Brazil. E-mail [email protected] O presente artigo teve como objetivo discutir as alterações no parênquima testicular, analisados através da ultra-sonografia, e correlacionar com os parâmetros biométricos testiculares e concentração de testosterona em búfalos mestiços. Dezenove touros, mestiços das raças Murrah x Mediterranea, com idade inicial entre 11 e 59 meses, foram submetidos a coletas quinzenais de sêmen por um período de seis meses. A cada coleta foram avaliados dados sobre a biometria e ecogenicidade testicular, quando amostras de sangue foram coletadas para a determinaçãodos níveis de testosterona no plasma. Os dados foram submetidos à análise de variância pelo procedimento GLM, considerando o efeito fixo faixa etária. Os dados médios obtidos foram comparados pelo teste de Duncan, a 5% de significância. Houve uma diferença, P <0,05) em causa a circunferência escrotal, que variou de 12,88 ± 0,51 cm a 31,18 ± 0,75 centímetros entre os animais com idade entre 12 a 60 meses, bem como o volume testicular, que variou de 30,28 ± 17,37 para 611,96 ± 38,69 cm³ entre os animais. A intensidade ecogênica do parênquima testicular variou em pixels a partir de 78,67 ± 6,36-109,24 ± 3,13 em animais com idade de 12 a 60 meses, respectivamente. Nos animais com idades entre 12 e 19 meses foi observado níveis de testosterona considerados diminuídos, enquanto que nos animais de 20 a 21 meses, houve um aumento progressivo nos níveis de testosterona, que tem seu pico nos animais com idade superior a 60 meses. Portanto, por meio de ultrassonografia, foi possível detectar diferenças na ecogenicidade entre animais pré-púberes e sexualmente maduros, podendo-se predizer que a ultrassonografia testicularé uma ferramenta importante na seleção destas características

    This study aimed to verify the effect of GnRH at the time of artificial insemination and Dominant follicle (DF) diameter on the Pregnancy rate (PR). 384 multiparous upgraded Murrah breed buffalo within 30 to 60 days postpartum with a body condition score of 3.4±0.6 were used. The synchronization protocol consisted of a day 0 (D0) intravaginal device of 1g of P4, application of 2.0mg of BE, and administration of 10 ml of injectable mineral supplementation at 4 pm. On D9, at 4 pm, the device was removed, and injected 0.265 mg of PGF2α and 300 IU of eCG Intramuscular (IM). On day 11, females were categorized based on the size of their dominant follicles. Females with ≥ 13 mm DF were divided into two groups: group 1 received GnRH, while group 2 did not. Similarly, females with &lt; 13 mm DF were split into Group 3, which received GnRH, and Group 4, which did not. At 4 pm, 0.1 mg of GnRH was administered IM according to their groups. On D12, 16 hours after the injection of GnRH (at 8 am), Fixed-time artificial insemination (FTAI) was performed. The pregnancy was diagnosed after 30 days of FTAI by ultrasound. The overall PR was 53.9% (207/384). No significant difference was observed between the groups and follicular size. More pregnancies were observed when the follicle size was around 13mm. It was concluded the administration of GnRH could enhance the efficiency of FTAI in buffaloes

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Nutrição, Florianópolis, 2010Introdução e objetivo: Analisar a associação do ângulo de fase padronizado (AFP) com parâmetros nutricionais e inflamatório de pacientes com afecções cirúrgicas. Métodos: Estudo transversal, 121 pacientes (48,2 ± 14,3 anos), admitidos para realização de cirurgia gastrintestinal eletiva ou de hérnia. Todas as avaliações foram realizadas no período pré-operatório: Avaliação Subjetiva Global (ASG), albumina e transferrina séricas, linfócitos totais, Índice de Risco Nutricional (IRN) e a atividade inflamatória através da proteína C-reativa ultra-sensível (PCR-us). Estes parâmetros foram comparados com o AFP, obtido a partir da Análise por Impedância Bioelétrica (BIA). Resultados: Houve fraca concordância ( = 0,275) entre o AFP e a ASG. O AFP foi correlacionado com a transferrina (r = 0,288) e albumina (r = 0,372) séricas, com o IRN (r = 0,484) e com a PCR-us (r = -0,178). Os pacientes em risco nutricional, conforme o IRN ou desnutridos de acordo com a ASG, albumina e transferrina séricas, assim como àqueles com alterações nas concentrações de PCR-us, apresentaram valores de AFP significativamente menores do que os pacientes bem nutridos e sem inflamação. Conclusão: Não houve boa concordância entre o AFP e a ASG, no entanto, o AFP foi correlacionado com os demais parâmetros nutricionais, demonstrando detectar alterações do estado nutricional nesta população de pacientes. Unitermos: avaliação do estado nutricional, rastreamento nutricional, ângulo de fase, marcadores bioquímicos, inflamação, pacientes hospitalizados.Background & Aims: To investigate the association between the standardized phase angle (SPA) and the inflammatory and nutritional parameters in patients with surgical disorders. Methods: Cross-sectional study, 121 adults# patients (48,2 ± 14,3 years), admitted for gastrointestinal surgery or hernia repair. The nutritional status was evaluated according to the Subjective Global Assessment (SGA), serum albumin and transferrin, total lymphocytes count (TLC) and the Nutritional Risk Index (NRI). The inflammatory activity was assessed by high sensitive C-Reactive Protein (hs-CRP). These parameters were compared with the SPA, obtained by Bioelectrical Impedance Analysis (BIA). Results: There was a weak agreement ( = 0,275) between the SPA and SGA. The SPA was correlated to serum transferrin (r = 0,288) and albumin (r = 0,372), to NRI (r = 0,484) and to hs-CRP (r = -0,178). Nutritional risk patients, detected by NRI, and malnourished patients diagnosed by SGA, serum albumin and transferrin, as well as those with inflammatory activity had a statistically significant lower median SPA as compared to those who were well-nourished and without inflammation. Conclusion: There was not good agreement between the SPA and SGA. Nevertheless, the SPA was correlated to the other methods investigated, indicating its ability on detecting alterations of nutritional status in this population of patients

    Tese (doutorado) - Universidade Federal de Santa Catarina, Centro de Desportos, Programa de Pós-Graduação em Educação Física, Florianópolis, 2011Objetivo: Verificar a prevalência de fatores de risco cardiovasculares em adolescentes e analisar a associação da lipemia sérica, variabilidade alélica dos polimorfismos rs662799 do gene APOA5 e rs693 do gene APOB, gordura corporal e aptidão cardiorrespiratória em adolescentes e seus pais com ancestralidade européia. Métodos: Estudo transversal conduzido em adolescentes (11-17 anos) e seus respectivos pais do município de Saudades-SC. Participaram das análises descritivas e de prevalência, 274 adolescentes. Para a descrição das análises do polimorfismo -1131T>C do gene APOA5 foram analisados 173 adolescentes (78 pais e 95 mães); e, para a análise do polimorfismo XbaI do gene APOB, 213 adolescentes (121 pais e 158 mães). As variáveis investigadas foram: demográficas (sexo, idade e área de domicílio), maturação sexual, antropométricas (massa corporal, estatura, perímetro do abdôme, gordura corporal relativa), bioquímicas (colesterol total, HDL-c, LDL-c e triglicerídeos), genéticas [polimorfismos rs662799 do gene APOA5 (-1131T>C) e rs693 do gene APOB (XbaI)] e aptidão cardiorrespiratória. Resultados: Verificou-se que 12,3%, 42,9% e 59,8% dos adolescentes tinham excesso de peso, obesidade abdominal e gordura corporal alta, respectivamente. Ademais, 46% apresentaram níveis reduzidos de HDL-c, 41,9% hipercolesterolemia, 18,0% níveis elevados de LDL-c e 13,6% hipertrigliceridemia. Adolescentes com excesso de peso corporal apresentaram mais chance de terem níveis reduzidos de HDL-c. Nenhuma diferença foi verificada nos valores médios da lipemia sérica entre as variantes alélicas do polimorfismo -1131T>C do gene APOA5 e XbaI do gene APOB. Em relação às diferenças entre os sexos, observou-se que as moças portadoras do genótipo TT do polimorfismo -1131T>C do gene APOA5 apresentaram médias mais altas de colesterol total, LDL-c e triglicerídeos quando comparadas aos rapazes. Além disso, observou-se que aquelas portadoras do genótipo TC+CC apresentaram médias mais elevadas de triglicerídeos que os rapazes. A partir das análises de associação, filhos de pais com gordura corporal elevada tinham quase quatro vezes mais chance de apresentarem níveis reduzidos de HDL-c (pC do gene APOA5 e XbaI do gene APOB dos pais e a lipemia sérica em adolescentes. Conclusão: Não foi verificada associação da lipemia sérica com as variantes alélicas do polimorfismo -1131T>C do gene APOA5 e XbaI do gene APOB entre adolescentes e seus pais.Objective: To examine the prevalence of cardiovascular risk factors in adolescents and to determine the association between serum lipemia, the variability of allelic polymorphisms rs662799 of the APOA5 gene and rs693 of the APOB gene, body composition and cardiorespiratory fitness in adolescents and their parents with European ancestry. Methods: Cross-sectional study conducted in adolescents (11-17 years) and their parents in Saudades-SC. Participating in the descriptive analysis and prevalence, 274 adolescents. For a description of the analysis -1131T>C polymorphism APOA5 gene were examined 173 adolescents (78 mothers and 95 fathers) and, for the analysis of XbaI polymorphism APOB gene, 213 adolescents (121 fathers and 158 mothers). Variables were: demographics (gender, age and area of residence), sexual maturation, and anthropometric (weight, height, abdome circumference, relative body fat), biochemical (total cholesterol, HDL-c, LDL-c and triglycerides), genetic [polymorphisms rs662799 of the APOA5 gene (-1131T>C) and rs693 of the APOB gene (XbaI)] and cardiorespiratory fitness. Results: We found that 12.3%, 42.9% and 59.8% of adolescents, respectively, overweight, abdominal obesity and high body composition. Furthermore, 46% have low levels of HDL-c, 41.9% hypercholesterolemia, 18.0% and 13.6% had high LDL-c and hypertriglycerimia, respectively. Adolescents with overweight have greater odds of having low levels of HDL-c. Regarding the differences between the genders, it was observed that the girls carrying the TT genotype of polymorphism -1131T>C in APOA5 gene had higher mean total cholesterol, LDL-C and triglycerides when compared to boys. In addition, we found that those girls with the TC+CC genotype showed higher triglyceride levels than boys. From the analysis of association, children of parents with high body fat were nearly four times more likely to have reduced levels of HDL-C (pC and APOA5 gene XbaI gene ApoB serum lipemia parents and adolescents. Conclusion: There was no association of serum lipemia with allelic variants of the polymorphism -1131T>C of the APOA5 gene and XbaI of the ApoB gene between adolescents and their parents

    Follicular Dynamics and Pregnancy Rate in Nellore Heifers Submitted to Fixed-Time Artificial Insemination Protocols (FTAI)

    SIMPLE SUMMARY: Reproductive biotechnologies are important strategies to enforce the production of genetically superior animals. The fixed-time artificial insemination is widely used in Brazil and it is especially important in farms located in remote areas, contributing to a better management and increase in genetics and productivity in areas such the Lower Amazon. We evaluated two different protocols of fixed-time insemination using two different hormones in the Nellore heifer raised under tropical conditions. The protocol of the fixed-time artificial insemination using equine chorionic gonadotrophin presented a better outcome in the pregnancy rate compared to the protocol using follicle stimulating hormone. Our tested protocol may be the most suitable alternative to increase conception rates in animals that are raised in an extensive system under tropical conditions in the Amazon. ABSTRACT: This study aimed to evaluate follicular dynamics and pregnancy rates in Nellore heifers submitted to fixed-time artificial insemination (FTAI) protocols associated with equine chorionic gonadotrophin (eCG) or follicle stimulating hormone (FSH). Nellore heifers (n = 259) were used, divided into two studies. Experiment I evaluated the ovarian follicular dynamics in 64 Nellore heifers submitted to different FTAI protocols (n = 32/group) using either FSH or eCG. In Experiment II, the pregnancy rate was evaluated in 195 heifers submitted to FTAI protocols and divided into two groups: FSH (n = 97) and eCG (n = 98). In Experiment I, the ultrasound examination showed that the maximum diameter of the dominant and preovulatory follicles and the ovulation time were similar between the FSH and eCG groups (p > 0.05). However, the ovulation rate was higher in the eCG group when compared to FSH (p = 0.014). In Experiment II, females that received eCG presented a higher pregnancy rate (58.1%) when compared to FSH (40.2%) (p = 0.012). The use of eCG in the FTAI protocol in Nellore heifers promoted a higher ovulation rate and increased pregnancy rate and may be the most suitable alternative to increase conception rates in animals that are raised in an extensive system under tropical conditions in the Amazon

    ilustraciones, fotografías a color, gráficas, tablasLivestock production extension in Amazon has caused deforestation and soil degradation, with negative consequences on biodiversity and environmental services. While the rubber plantations establishment has arisen as a productive and restoration alternative degraded livestock soils. This study evaluated differences in termite assemblage and functional structure in three different rubber crop systems as an indirect way of evaluating soil diversity restoring. Three rubber crop systems were sampled: clonal fields (CF), traditional commercial rubber plantations (CR), and mixed plantations (MX). Additionally, livestock pastures (PA) and natural forest relicts (NF) were compared to rubber crop systems, to serve as reference habitats. Termites were sampled using the transect method. From 80 species collected, 3.8% corresponded to Rhinotermitidae family, and 96.2% to Termitidae family. The natural forest was the land use with the highest richness (54 species) and species occurrence (437 occurrences). Species richness in rubber crop systems were 39% higher than in pastures and included 72% of the termite species found in natural forests. The land uses were clustered according to their diversity: group I of high diversity (CR and NF) and group II of low diversity (CF, MX and PA). Among the 14 soil variables that were evaluated, organic carbon, bulk density and electrical conductivity were the variables that most influenced the termite communities. Soil-feeders termites were associated with less diverse land uses and wood-feeders were associated with high diverse land uses. Pastures and MX presented the lowest values in diversity, but each functional structure was different. Elseways, functional structure of CR was similar to the natural forests. Our results demonstrate that termite diversity and functional structure recovery is possible and will depend on the rubber crop system selected.La ganadería extensiva en la amazonia ha causado deforestación y degradación en el suelo, con consecuencias negativas en la biodiversidad y servicios ambientales. Mientras el establecimiento de plantaciones de caucho ha surgido como una alternativa productiva y de restauración para suelos degradados por la ganadería. Este estudio evaluó las diferencias en los ensamblajes y la estructura funcional de las termitas en tres diferentes cultivos de caucho como una forma indirecta de evaluar la restauración de la diversidad del suelo. Tres sistemas de cultivos de caucho fueron muestreados: campos clonales (CF), plantaciones comerciales (CR) y plantaciones mixtas (MX). Adicionalmente, pasturas ganaderas (PA) y bosques naturales (NF) sirvieron como ecosistemas de referencia. Las termitas se muestrearon usando el método de transecto. De las 80 especies colectadas, 3.8% correspondía a la familia Rhinotermitidae y el 96.2% a la familia Termitidae. El bosque natural fue el uso de la tierra con mayor riqueza (54 especies) y ocurrencia de especies (437 ocurrencias). En los sistemas de cultivo de caucho fue 39% mayor que en pasturas e incluyeron el 72% del total de especies encontradas en los bosques naturales. Los usos de suelo fueron agrupados de acuerdo con su diversidad: grupo I de alta diversidad (CR y NF) y grupo II de baja diversidad (CF, MX y PA). Dentro de las 14 variables de suelo que se evaluaron, carbón orgánico, densidad aparente y conductividad eléctrica fueron las variables que más influenciaron sobre las comunidades de termitas. Las termitas consumidoras de suelo estuvieron asociadas con usos de suelo de baja diversidad y las xilófagas estuvieron asociados con usos de suelo de alta diversidad. Pasturas y MX presentaron la diversidad más baja, pero sus estructuras funcionales fueron diferentes en sí. Por otro lado, la estructura funcional de CR fue similar a la de NF. Nuestros resultados demostraron que recuperar la diversidad y la estructura funcional de las termitas es posible y dependerá de las prácticas de manejo del cultivo de caucho.
