background: in the field of mammalian embryo culture, the putative influence of autocrine/ paracrine factor(s), produce by the embryos itself, is under investigation. a smaller medium drop can prevent dilution of this factor(s). objective: the objective of this study was to examine the effect of culture medium volume on in vitro development of mouse 2-cell embryos. materials and methods: the em...

We separated platelets from whole blood and incorporated them into In-Ill and Te-99m agents. Sn-GHA, Tropolone, Oxine (sulphate) and HMPAO were used to diffuse radionuclides into the platelets. The effects of time, temperature, PH of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m C13 and Te-99m on labeling efficiency were studied.

A total of 2160 images of candled, incubated ostrich eggs were digitized to determine the percentage of egg volume occupied by the air cell at different stages of incubation. The air cell on average occupied 2.5% of the volume of fresh eggs. For eggs that hatched successfully, this volume increased to an average of 24.4% at 41 days of incubation, just prior to hatching. Air cell volume at 29 da...

In this study, the relationships between weight, volume and specific gravity of eggs are revealed by calculating egg's depending on weight egg, breadth length, which only three variables, with mathematical equations. Eggs to goose genotypes, Grey China, Linda Native geese from Aksaray region taken six breeders were used. (n=481) weighed Length, Breadth measurements made a precision 0.01 mm. Ave...
