However, neither e strontium and ethanol individually, nor the association of both were efficient to produce parthenogenetic blastocysts.
Intense emission was observed for strontium with hydrogen gas, but no emission was observed with hydrogen or strontium alone.
Only one calf was obtained in the group activated with ionomycin and strontium.
A live female calf was obtained when ionomycin/strontium were used, but it died 30 days after birth.
This work is supported by partial strontium isotope data that clarify some key biostratigraphic problems.
All samples have been analysed for strontium isotope ratios; these fall in the range 0.70645 to 0.70710.
The previously suggested correlation is not valid even if the strontium isotope system was reset.
Post-depositional contamination of tooth enamel (diagenesis) is normally not significant in strontium-isotope studies.
The presence of diagenetic strontium in an enamel sample could mask evidence for migration.
The ability of embryos activated in strontium to undergo blastocyst development, establish pregnancy and generate live newborn was evaluated.
Strontium-isotope studies have focused on tooth enamel rather than bone.
It should also be noted that strontium-isotope ratios in rock commonly vary from the ratios measured for fauna and flora.
When artificial stimulation with strontium was used, the fertilization of oocytes with heated or ethanol-treated spermatozoa was completely rescued.
Virtually all strontium in vertebrate organisms is found in the skeleton.
