Effect of gas atmosphere on the development of one-cell bovine embryos in two culture systems

Autor: Y.X. Hu, S.A. Voelkel

Publikováno v: Theriogenology. 37:1117-1131

The effect of two concentrations of oxygen on the development of bovine embryos was compared using two separate co-culture systems. In Experiment I, bovine oocytes were matured and fertilized in vitro and were then co-cultured for 7 days in 20 mul dr

Direct transfer of frozen-thawed bovine embryos

Autor: Y.X. Hu, S.A. Voelkel

Publikováno v: Theriogenology. 37:23-37

The ability to transfer frozen embryos directly to recipient females after thawing would be a convenience in embryo transfer and would facilitate marketing embryos produced in large quantities by in vitro procedures. Techniques for direct transfer of

Autor: J.D. Roussel, Anzalone Ca, S.A. Voelkel, Goodeaux Ll, J.K. Thibodeaux

Publikováno v: Journal of Medical Primatology. 19:493-499

Refractometer indexes were standardized and found to be highly correlated (r = 0.831) to actual creatinine levels. Urinary estradiol corrected by creatinine levels and refractometer indexes were found to be highly correlated (r = 0.857). Predicted ov

Successful nonsurgical collection of Macaca mulatta embryos

Autor: C.A. Anzalone, L.L. Goodeaux, J.K. Thibodeaux, J.D. Roussel, Yves Menezo, S.A. Voelkel

Publikováno v: Theriogenology. 34:1159-1167

A nonsurgical flushing technique was used to recover preimplantation embryos from the rhesus uterus. Natural breeding was allowed from Day 9 (Day 1 = first day of observed menses) of the menstrual cycle until 2 d following urinary estradiol peak. Non

Nonsurgical Technique for Flushing the Macaca mulatta Uterus

Autor: K.H. Graves, Goodeaux Ll, Webre Mk, Anzalone Ca, S.A. Voelkel

Publikováno v: Journal of Medical Primatology. 19:59-67

The tortuous structure of the rhesus cervix has proven to be a significant obstruction to performing nonsurgical uterine lavage. Trials were conducted to develop a repeatable, nonsurgical flushing technique of the uterus. Using a modified endometrial

Use of ethylene glycol as a cryoprotectant for bovine embryos allowing direct transfer of frozen-thawed embryos to recipient females

Autor: S.A. Voelkel, Y.X. Hu

Publikováno v: Theriogenology. 37(3)

Four experiments were conducted to define a system for the direct transfer of frozen-thawed bovine embryos to recipient females. In Experiment I, nonsurgically recovered embryos were frozen in 1.5 M ethylene glycol (EG), 1.5 M propylene glycol (PG),
