Transfer of two demi embryos increases pregnancy rate but not the birth rate. Author(s): VIANA, J. H. M. Repository: BDPA Publication year: 2015
Effect of luteal blood flow and number of corpora lutea on the pregnancy rate after fixedtime embryo transfer of cryopreserved embryos in Lacaune recipients evaluated by Color Doppler ultrasonography. Author(s): FONSECA, J. F. da Abstract: The Doppler ultrasonography allows the characterization of blood flow and estimation of the functionality of reproductive organs. Therefore, it shows a great potential for use in multiple ov... ... Repository: BDPA Publication year: 2019
Evaluation of factors affecting pregnancy rate in bovine embryo recipients after estrous synchronization for fixed-time embryo transfer. The aims of this study were to evaluate the efficacy of a hormone protocol for fixed time embryo transfer, and to investigate factors usually associated with the achievement of high pregnancy rates in... ... Repository: BDPA Publication year: 2008
Pregnancy rates and corpus luteum-related factors affecting pregnancy establishment in bovine recipients synchronized for fixed-time embryo transfer. Author(s): SIQUEIRA, L. G. B.; CAMARGO, L. S. de A.; VIANA, J. H. M. The objective was to investigate the influence of corpora lutea physical and functional characteristics on pregnancy rates in bovine recipients synchronized for fixed-time embryo transfer (FTET). Cros... ... Repository: BDPA Publication year: 2009
Treatment of in vitro produced embryos with colonystimulating factor 2 during culture in the presence of serum does not affect pregnancy rates after embryo transfer. Author(s): CAMARGO, L. S. de A.; VIANA, J. H. M.; SIQUEIRA, L. G. B. Repository: BDPA Publication year: 2024
Imprinted gene expression in in vivo- and in vitro-produced bovine embryos and chorio-allantoic membranes. Author(s): NICIURA, S. C. M. Cloning by nuclear transfer is often associated with poor results due to abnormal nuclear reprogramming of somatic donor cells and altered gene expression patterns. We investigated the expression patt... ... Repository: BDPA Publication year: 2009
Chemically induced enucleation of activated bovine oocytes: chromatin and microtubule organization and production of viable cytoplasts. Author(s): OLIVEIRA, C. S. As the standard enucleation method in mammalian nuclear transfer is invasive and damaging to cytoplast spatial organization, alternative procedures have been developed over recent years. Among these t... ... Repository: BDPA Publication year: 2015
Effect of nanoatrazine on the growth of aquatic bioindicators through trophic transfer. Author(s): CASTANHA, R. F.; VALLIM, J. H.; CASTRO, V. L. S. S. de; JONSSON, C. M. Abstract: Atrazine is a herbicide that has stood out in recent years for being one of the most commercialized pesticides in the country, being used to control weeds, mainly in corn, sugar cane and sor... ... Repository: BDPA Publication year: 2023
Freezing goat embryos at different developmental stages and quality using ethylene glycol and a slow cooling rate. Author(s): FONSECA, J. F. da; VIANA, J. H. M. Abstract: The efficiency of an alternative freezing protocol for goat embryos of different morphology and quality was tested. Fifty-eight embryos on Day 6-7 stage were transferred as fresh or after fr... ... Repository: BDPA Publication year: 2018
Transferibilidade de marcadores microssatélites desenvolvidos a partir de RNA-Seq de amendoim forrageiro. Author(s): FORMIGHIERI, E. F.; SILVA, L. M. da; CAMPOS, T. de O amendoim forrageiro (Arachis pintoi) apresenta destaque expressivo que traduz a sua importância econômica e ambiental em pastagens. Porém, ainda são poucas as variedades disponíveis para cultivo. O... ... Repository: BDPA Publication year: 2021
