Yolk-shell NiS2/carbon spheres (yolk-shell NiS2/C) have been synthesized by one-step annealing of yolk-shell Ni-metal-organic framework spheres. In particular, both the inner yolk sphere and the outer shell of yolk-shell NiS2/C can provide catalytically ...

In Ophryotrocha labronica LaGreca & Bacci mature yolk granules are found only in the ovocyte. Other typical yolk elements are lipid droplets, small vesicular bodies, multivesicular bodies and dense bodies. The two last-mentioned also appear in the accompanying nurse cell and from there obviously pass over unchanged into the ovocyte through a specific ...

Hemopoiesis in the human yolk sac
American Journal of Anatomy, 1989AbstractThe endodermal layer of the human yolk sac was examined three‐dimensionally with light microscopy on serial sections using scanning electron microscopy and transmission electron microscopy to find the origin of hemo poiesis in the yolk sac. Cell‐labelling techniques were also employed using the monoclonal anti‐transferrin receptor antibody ...

Graphitic carbon nitride (g-C3N4) was hybridized by hierarchical yolk–shell TiO2 spheres via a solvothermal method by mixing the as-prepared g-C3N4 with the precursor of the TiO2 yolk–shell spheres in dimethylformamide (DMF). The introduction of DMF made

SUMMARYThis investigation was initiated to separate the unsaponifiable matter of egg yolk by thin layer chromatography (TLC) and attempt to identify the steroids by gas liquid chromatography (GLC). Three GLC liquid phases, differing in selective partition properties, were used to aid in the identification of unknown steroids.

WE administered labelled (radioactive) sodium phosphate to a hen by subcutaneous injection and, after the lapse of 28 hours, removed 34 yolks from the ovary having an aggregate weight of 30·6 gm. The lecithin of each yolk was then extracted and the phosphorus content and radioactivity determined.
