Induction of Ovulation in Mangalarga Marchador Mares by hCG or GnRH

Background: Induction of ovulation is a key procedure for horse assisted reproduction technologies, such as for artificial insemination (AI) and embryo transfer. The application of hCG remains as the primary ovulation-inducing agent for horse assisted reproduction, but alternatives are in demand to avoid its adverse effects, such as loss of ovulation-inducing efficiency over multiple applications by hCC-antibody production. Despite reports on alternative ovulation-inducing agents, pair-wise comparisons of such agents under similar conditions have been limited. Under such scenario, the work was aimed to determine the efficiency of both hCG and Buserelin at inducing ovulation in Mangalarga Marchador mares raised in the Northeast of Brazil under an AI program.Materials, Methods & Results: Mares were initially selected based on their reproductive performance, the absence of clinical-reproductive alterations and adequate body condition score. Mares in diestrus were randomly distributed in three experimental conditions, received 5 mg of Dinoprost and were monitored daily for estrus detection. After estrus detection, ovaries were monitored by ultrasonography, in 12-h intervals, until the follicle reached 35 mm. At this time-point, ovulation was induced with 0.042 mg of Buserelin endovenously, with 3,000 IU hCG by an intramuscular shot, and control mares received 2 mL of saline solution, also by an intramuscular shot. Both hCG and Buserelin displayed similar efficiencies (P > 0.05) for induction of ovulation and that both agents were effective (P 0.05) from those found in the Control. All ovulations occurred within a 72-h period after treatment. It can be observed that in mares treated with hCG or Buserelin, ovulations occurred both in more mares (P 0.05) between hCG and Buserelin groups, and that pregnancy of mares treated with ovulation-inducing factors was similar to the control.Discussion: The majority of ovulations in mares occurred within initial 48-h after treatment for both hCG and GnRH, suggesting a similar potential for horse assisted reproduction. Both hCG and Buserelin are two commonly used agents for induction of ovulation in mares. As described here, the majority of ovulations occurred within initial 48-h after treatment, a fact which can be attributed to hCG and GnRH activity, since it can happen in intervals from 36 to 48-h after treatment. Pregnancy rates did not differ among groups. These results are under the working hypothesis that hCG and Buserelin would display similar efficiencies on pregnancy rates. Despite the understanding of hCG activity on induction of ovulation due to its high specificity toward LH receptors and results from a direct effect on diminishing estradiol concentration, increasing LH, and further inducing ovulation within 48-h after treatment. In contrast, Buserelin has a similar functional property but acts upon LH synthesis and its release. In conclusion, ovulation in mares can be induced with both hCG and Buserelin, and both ovulation-inducing agents do not affect pregnancy rates

Compressão aguda de cauda equina por cisto sinovial inflamatório – Relato de caso

Objetivo: Relatar uma causa rara de compressão radicular em coluna evidenciando as complicações clínicas bem como a proposta terapêutica. Descrição do caso: Apresentamos o caso de um idoso com 78 anos, sem comorbidades, ativo, que desenvolveu um quadro de lombociatalgia bilateral e dificuldade de marcha. O exame de ressonância magnética da coluna lombar evidenciou nódulo intrarraquiano comprimindo o aspecto posterior e lateral esquerdo do saco dural a nível L4-L5. Devido à rápida piora dos sintomas neurológicos, realizou-se laminectomia com excisão cirúrgica do nódulo e descompressão da cauda equina. A biópsia do nódulo evidenciou a presença de tecido inflamatório. Considerações finais: Apesar de ser um acontecimento raro, os cistos sinoviais lombares podem resultar em compressão das estruturas medulares. A ressonância magnética é o exame de imagem de escolha para diagnosticá-los, além de proporcionar a exclusão de outras causas. O prognóstico é favorável se a conduta terapêutica for tomada de modo célere e adequado

ATEROSCLEROSE DE CARÓTIDA: ASSOCIAÇÃO ENTRE O LADO ACOMETIDO COM FATORES DE RISCO E DOENÇAS SISTÊMICAS

  Introduction: Atherosclerosis is a degenerative disease of multicausal etiology. Different risk factors (genetic and acquired) acting together can determine its occurrence. Objective: Considering the epidemiological importance of atherosclerosis, it was decided to study it by ultrasonography and to observe its association between the affected side (right, left, both sides) with risk factors, such as: age, gender, arterial hypertension, smoking and diabetes mellitus. Methodology: The data were obtained from the analysis of service forms, provided by a private clinic in Imperatriz – MA, that offers the service of doppler of carotid, in the period from January to December 2016. The objective of the ultrasonography examination was to locate and quantify carotid atherosclerotic lesions. Result: 50 individuals were studied, whose age range varied from 42 to 86 years, with an average age of 69,72 years (± 9,43), of which 31 (62%) were female and 19 (38%) males. Of this population, 13 (26%) had diabetes mellitus, and 11 (22%) were smokers, 38 (76%) individuals were hypertensive and 22 (44%) had previous history of stroke. Conclusion: Although the studies show diferences in the degree of atherosclerotic development when compared to the side of the carotid artery, there is no specific correlation between the side affected (right, left, both sides) with the risk factors (gender, smoking) and systemic diseases (stroke, diabetes mellitus and arterial hypertension).  Introdução: A aterosclerose é uma doença degenerativa de etiologia multicausal. Diferentes fatores de risco (genéticos e adquiridos) atuando em conjunto podem determinar sua ocorrência. Objetivo: Considerando a importância epidemiológica da aterosclerose, resolveu-se estudá-la por meio da ultrassonografia e observar sua associação entre o lado acometido (direito, esquerdo, ambos os lados) com fatores de risco, como: idade, sexo, hipertensão arterial, tabagismo e diabetes melito. Metodologia: Os dados foram obtidos a partir da análise de fichas de atendimento, disponibilizadas por uma clínica particular de Imperatriz – MA, que oferece o serviço de doppler de carótida, no período de janeiro a dezembro de 2016. O exame ultrassonográfico teve como objetivo a localização e quantificação de lesões ateromatosas das carótidas. Resultado: Foram estudados 50 indivíduos, cuja a faixa etária variou de 42 a 86 anos, com idade média de 69,72 anos (± 9,43), dos quais 31 (62%) eram do sexo feminino e 19 (38%) masculino. Dessa população, 13 (26%) eram portadores de diabetes melito, e 11 (22%) eram tabagistas, 38 (76%) indivíduos eram hipertensos e 22 (44%) tinham história pregressa de acidente vascular cerebral. Conclusão: Embora os estudos evidenciem diferenças no grau de desenvolvimento aterosclerótico quando comparado o lado da artéria carótida acometida, demonstra-se não haver correlação específica ente o lado acometido (direito, esquerdo, ambos) com os fatores de risco (sexo, tabagismo) e doenças sistêmicas (acidente vascular cerebral, diabetes melito e hipertensão)

Evaluation of Corpus Luteum Vascularization in Recipient Mares by Using Color Doppler Ultrasound

Background: Embryo transfer is one of the most commonly used reproductive biotechnique. The success of embryo transfer is also affected by the synchrony of estrus and ovulation between donor and recipient animals. In horse reproduction, ultrasonography has been used, among other purposes, to diagnose early pregnancy. However, only the color Doppler imaging mode makes it possible to evaluate the vascular architecture and the hemodynamic aspects of the vessels in several organs, especially the corpus luteum. The objective of this study was to evaluate, based on the color Doppler ultrasound, the corpus luteum vascularization and function from recipient mares at embryo transfer timing.Materials, Methods & Results: Mangalarga Machador mares from 5 to 10-year-old and a range of live weights of between 350 to 450 kg were used for this experiment, kept in pasture-based on mombaça grass (Panicum maximum) and were given ad libitum access to water and mineral supplementation. The animals (n = 15) were gynecologically examined and uterine consistency was evaluated by rectal palpation the same operator using an ultrasound system (SonoScape®) with a linear transducer, and operating frequency ranging from 5 to 10 Mhz. The uterine tone was classified between grades 1 and 4 and subjected to ovulation induction. The objective and subjective vascular perfusion of the corpus luteum was evaluated by color Doppler ultrasound on the day of embryo transfer and endometrium. The determination progesterone concentration on the day of the embryo transfer was performed by direct chemiluminescence assay. The arcsine (√P/100) transformation was applied to the percentage data, and the results were expressed as mean (.) ± standard error of the mean (SEM). Further, the assumptions of normality and homoscedasticity were verified, respectively, based on the Shapiro-Wilk and Lilliefors tests. Regarding the parametric and non-parametric variables, were applied, respectively, analysis of variance (ANOVA) followed by Tukey’s test, and the Kruskal-Wallis test followed by Dunn’s test. Pearson’s correlation coefficient was used to evaluate the relationship between the parameters. The statistical program SPSS 16.0 was used to perform the over-mentioned analyses, and a p-value 0.05).Discussion: Mares that later became pregnant showed a higher concentration of progesterone as an outcome of the higher vascularization in the corpus luteum. It can be supported by both the correlation between the progesterone concentration and the corpus luteum vascular perfusion, as well as by the higher values of the vascular perfusion in pregnant mares. Based on the results, it has been concluded that the color Doppler ultrasound evaluation is an accurate tool to determine the corpus luteum vascularization, whether considering the objective or subjective methods. Also, the vascular perfusion is the most efficient parameter to determine both the corpus luteum function and to predict the ability of the recipient mares to maintain pregnancy

Influence of different adhesion strategies on glass fiber post retention

Failures in glass fiber post (GFP) retention may be associated with low adhesion achieved in root dentin.55 single-rooted premolars were endodontically treated and distributed according to different adhesion strategies (n=11): G1: RelyX ARC (3M ESPE; etch-rinse strategy); G2: Relyx Ultimate (3M ESPE; etch-rinse strategy); G3: AllCem (FGM; etch-rinse strategy); G4: Relyx Ultimate (3M ESPE; self-etching strategy); G5: RelyX U200 (3M ESPE; self-adhesive strategy). For Bonding Strength (BS) analysis, the roots were sectioned in slices (1.0mm thickness) corresponding to each root third and submitted to push-out test. The type of failure was assessed by scanning electron microscopy (SEM).The highest BS averages were found in G2 and G3. However, in the middle and apical root thirds, G3 showed statistically similar results to G4 and G5. In the cervical and middle third, G1 was statistically similar to G4 and G5. The mixed type of failure was the most common in all groups.Self-etching (G4) and self-adhesive resin (G5) cements, showed similar BS results of immediate bonding in the cementation of GFP compared to conventional resin cements (G1, G2, G3)

Identification of some Amazonian species of Culex (Culex) and Culex (Melanoconion) by morphotyping and barcoding

Os mosquitos Culex spp. apresentam características idiossincráticas e sua baixa variabilidade dificulta sua identificação. O objetivo do nosso estudo foi analisar a região 5 'do gene da subunidade I do citocromo oxidase (coI) para a identificação taxonômica de espécies de Culex que foram previamente diagnosticadas em subgêneros Culex e Melanoconion em condições de campo. Dez sequências de espécimes foram analisadas pelo Automatic Barcode Gap Discovery (ABGD). Todas as sequências apresentaram 94-99% de identidade quando comparadas com outras sequências de espécies de Culex disponíveis no GenBank. Cinco partições iniciais suportaram 80-88 grupos de espécies. Entre eles, oito conjuntos continham os espécimes do presente estudo. Das 10 sequências de mosquitos, cinco não formaram nenhum cluster consistente, e as demais apresentaram alguma consistência no diagnóstico taxonômico nas condições de campo. Nossos resultados sugerem que algumas sequências do gene coI de espécimes podem pertencer a espécies do subgênero Melanoconion, cuja sequência 5' coI é desconhecida ou inédita no GenBank.Culex spp. mosquitoes have idiosyncratic characteristics and its low variability makes difficult their identification. The aim of our study was to analyze the 5' region of the cytochrome oxidase subunit I gene (coI) for the taxonomic identification of Culex species which were previously morphotyped and diagnosed in Culex and Melanoconion subgenera at the field conditions. Ten specimen sequences were analyzed by the Automatic Barcode Gap Discovery (ABGD). All sequences showed 94-99% identity when compared to other Culex species sequences available from GenBank. Five initial partitions supported 80-88 species groups. Among them, eight sets contained the specimens of the present study. Of the 10 mosquito sequences, five did not form any consistent cluster, and the remaining showed some consistency in the taxonomic diagnosis at the field conditions. Our results suggest that some coI gene sequences of specimens may belong to species of the subgenus Melanoconion, whose 5’ coI sequence is unknown or unpublished in GenBank

Evaluation of clinical and reproductive parameters in Mangalarga Marchador mares treated with different doses of Cloprostenol or Dinoprost

Avaliou-se a ação de doses reduzidas e convencionais de substâncias luteolíticas sobre parâmetros clínicos e reprodutivos de éguas. As femeas receberam intramuscularmente, 125 ?g (n = 20) e 250 ?g (n = 20) de Cloprostenol e 2.5 mg (n = 20) e 5.0 mg (n = 20) de Dinoprost. A temperatura retal e as frequências cardíaca e respiratória foram aferidas antes e após a administração desses luteolíticos, considerando-se ainda a ocorrência de sudorese, diarreia, cólica e prostração. Monitorou-se o estro e o desenvolvimento folicular até a ovulação, quando realizou-se a inseminção artificial. A gestação foi diagnosticada com 300 e confirmada no 60o dia. Apenas as éguas tratadas com 2,5 e 5,0 mg de Dinoprost apresentaram alteração (P < 0.05) da frequência respiratória e os demais parâmetros não foram alterados (P > 0.05). A sudorese ocorreu em 5% e 10% das éguas tratadas, respectivamente, com 2.5 mg e 5.0 mg de Dinoprost e a diarréia em apenas 5% daquelas que receberam 5.0 mg desse luteolítico. As porcentagens de estro e prenhez das éguas tratadas com 125 ?g de Cloprostenol (45%/35%) e 2.5 mg de Dinoprost (50%/30%) foram menores (P < 0.05) do que os daquelas que receberam 250 ?g de Cloprostenol (85%/70%) e 5 mg de Dinoprost (90%/75%). O estro e a prenhez das éguas Controle foram menores (P < 0.05) do que nas tratadas. Conclui-se que apesar de não promoverem alterações significativas dos parâmetros clínicos, as doses reduzidas não apresentam as mesmas eficiências dos tratamentos com doses convencionais para induzir o estro
