Publikováno v: Rapid Communications in Mass Spectrometry. 23:1313-1320

Using the bovine species as a biological model, direct infusion chip-based nano-electrospray ionization mass spectrometry (nano-ESI-MS) fingerprinting in the positive ion mode is used to obtain fast chemical profiles of media used for in vitro produc

Comparison of embryo yield and pregnancy rate between in vivo and in vitro methods in the same Nelore (Bos indicus) donor cows

To investigate why the preferred means to produce bovine embryos in Brazil has changed from in vivo to in vitro, we compared these two approaches in the same Nelore cows (n=30) and assessed total embryo production and pregnancy rates. Without a speci

Pregnancy Rates to Fixed Embryo Transfer of Vitrified IVP Bos indicus, Bos taurus or Bos indicus × Bos taurus Embryos

Autor: J. H. Tannura, B. V. Sanches, A. G. Rigo, J.H.F. Pontes, L. S. R. Marinho, Marcelo Marcondes Seneda, Andrea Basso, Camila Oliveira Rosa

Publikováno v: Reproduction in domestic animals = Zuchthygiene. 50(5)

The pregnancy rates obtained after the transfer of cryopreserved in vitro-produced (IVP) embryos are usually low and/or inconsistent. The objective of this study was to evaluate the pregnancy rates of Holstein, Gyr and Holstein × Gyr cattle after th

Pregnancy rate and birth rate of calves from a large-scale IVF program using reverse-sorted semen in Bos indicus, Bos indicus-taurus, and Bos taurus cattle

Publikováno v: Theriogenology. 81(5)

Obtaining sexed sperm from previously frozen doses (reverse-sorted semen [RSS]) provides an important advantage because of the possibility of using the semen of bulls with desired genetic attributes that have died or have become infertile but from wh

In this work, we evaluated whether embryo development and pregnancy rates would be affected by culturing bovine Bos indicus embryos in Synthetic Oviductal Fluid with amino acids (SOFaa) or G1/G2 sequential medium under a low-oxygen atmosphere. Using

Cryosurvival and pregnancy rates after exposure of IVF-derived Bos indicus embryos to forskolin before vitrification

Publikováno v: Theriogenology. 80(4)

In vitro-produced (IVP) bovine embryos are more sensitive to cryopreservation than their in vivo counterparts due to their higher lipid concentrations, whereas Bos indicus IVP embryos are even more sensitive than Bos taurus IVP embryos. To examine th

Publikováno v: Journal of Lipid Research, Vol 51, Iss 5, Pp 1218-1227 (2010)

Methods used for lipid analysis in embryos and oocytes usually involve selective lipid extraction from a pool of many samples followed by chemical manipulation, separation and characterization of individual components by chromatographic techniques. H
