A study of genetic transformation in gloeocapsa alpicola
Devilly, C. I.; Houghton, J. A. (Microbiology Society, 1977-01-01) -
Association of foreign dna with porcine spermatozoa
Horan, R.; Powell, R.; McQuaid, S.; Gannon, F.; Houghton, J. A. (Informa UK Limited, 1991-01-01)The aim of this project was to establish if DNA molecules bind to procine spermatozoa after incubation in vitro. In an initial experiment, the DNA was mixed with porcine spermatozoa to test for the presence of DNases. ... -
Cytogenetics of porcine sperm chromosomes following ivf of zona-free hamster oocytes
Bird, J. M.; Houghton, J. A. (Informa UK Limited, 1990-01-01) -
Effects of electropermeabilization on the association of foreign dna with pig sperm
Horan, R.; Powell, R.; Bird, J. M.; Gannon, F.; Houghton, J. A. (Informa UK Limited, 1992-01-01)This study was conducted to evaluate the effects of an electric pulse (electroporation/electropermeabilization) on the binding of foreign DNA molecules to porcine spermatozoa. We previously examined various parameters ... -
Fluorescence in situ hybridization studies on the sex chromosome constitution of human sperm
Dineen, T.; Nolan, A.; Harrington, J.; Greer, A.; Kennedy, R.; Houghton, J. A. (Informa UK Limited, 1997-01-01)More males are conceived than females and more males are born as a result of in vitro fertilization (IVF) and donor insemination procedures. All donor sperm samples are frozen for a minimum of 6 months before they are used. ... -
The fate of foreign dna associated with pig sperm following the in vitro fertilization of zona-free hamster ova and zona-intact pig ova
Horan, R.; Powell, R.; Gannon, F.; Houghton, J. A.; Pellucida, Zona (Informa UK Limited, 1992-01-01)The aim of this study was to determine the fate of foreign DNA molecules bound to porcine sperm that had been capacitated and acrosome reacted in vitro using calcium ionophore and then used in the in vitro fertilization ...
