Effect of anti-egg-yolk-diluent sera upon bovine spermatozoa in egg yolk diluent
… designed to determine if the antigenicity of egg yolk diluter could be eliminated by the addition of specific antibodies. Two virgin heifers were immunized with 20% yolk - 2.1% citrate - 7% glycerol with penicillin and streptomycin. Non-immune serum and immune sera having titers of 1:640 and …

Enzymatic degradation of egg yolk cholesterol
… method for the determination cholesterol in egg yolk and processed foods was developed from a method of Kovacs (1990). A sample is heated in a sealed tube with a solution of potassium hydroxide in ethanol containing the internal standard, dihydrocholesterol. The sterols are then isolated by …

The Influence of Nucleic Acids of Yolk Origin on the Growth and Development of the Avian Yolk Sac
The problem of elucidating the genetic control mechanism of developing organisms is extremely- interesting to the developmental biologist. Our current knowledge of genetic control tells us that hereditary information is coded primarily into nuclear DNA, characteristic differentiated phenotypes …

Sulfur-Based Yolk-Shell Nanoparticles for Lithium Sulfur Batteries
… on the synthesis of gold-functionalized sulfur yolk-shell nanoparticles. Sulfur was chosen as a cathode material due to its high theoretical specific capacity (1675 mA h g−1). However, there are still many technical limitations for Li-S batteries, like the dissolution of the intermediate …

Laying-Sequence Variation in Yolk Carotenoids of Eastern Bluebirds
… We studied the laying-sequence variation in yolk carotenoids and egg metrics of nine full clutches of Eastern Bluebirds (<em>Sialia sialis</em>) in Columbus, Georgia. I predicted that Eastern Bluebirds would exhibit a brood reduction strategy, with the first-laid eggs containing a higher …

QX Pup : the fascinating yolk of the Rotten Egg Nebula
QX Pup is a known Mira variable at the core of the Rotten Egg Nebula that has not been studied in detail since its discovery in 1983. In this study, four years of photometric data in V and I and two years of photometric data in R and B are analyzed. A period of T = 535.4 ± 8 days, and a magnitude …

The Recovery of Protein from Egg Yolk Protein Extraction Granule Byproduct
… than the whole egg. At low speed centrifugation, yolk separates into two distinct fractions—granules and plasma. It is becoming increasingly popular in the industry to remove the plasma fraction of the egg yolk to use for its livetins, particularly immunoglobulin Y, leaving behind a granule …

An in vitro model of human yolk sac and epiblast crosstalk
… the hypoblast being the portion of the human yolk sac that lies adjacent to the epiblast. However, the functional role of such a structure within the context of human development is yet to be understood. In vitro stem cell modelling of the human yolk sac- epiblast interaction offers a system …

A new process for the separation and purification of egg yolk antibodies
… (IgY) from industrially separated chicken egg yolk. This included aqueous extraction of the water soluble fraction (WSF) from the yolk by dilution with distilled water and pH adjustment, separation of IgY from the WSF using a cation exchange column in an automated chromatography system, and …

The zebrafish maternal factor pollywog is required for yolk syncytial layer morphogenesis
In teleosts, the Yolk Syncytial Layer (YSL) is functionally similar to the anterior visceral endoderm found in mice and is required for morphogenesis of the overlying blastoderm. The YSL undergoes dramatic reorganization during early development through processes that mirror the morphogenetic …

A Manometric Analysis of Metabolic Activity in the Developing Chick Yolk Sac
The advance of the avian yolk sac over the surface of the yolk sphere offers a system exhibiting an extremely rapid growth rate with subsequent sudden decrease in this rate. To attempt.to understand the factors controlling such a growth phenomena, one approach is an inspection of the changes in …

Using Lipase to Improve the Functional Properties of Yolk-Contaminated Egg Whites
Egg yolk contamination of egg whites continues to be a serious problem in the egg industry. The ability of egg whites to form stable and voluminous foams is greatly inhibited by accidental yolk contamination, even at extremely small levels. Experiments were conducted to determine if lipase can …

Evaluation of Different Concentrations of Egg Yolk in Canine Frozen Semen Extender
This study tested different concentrations of egg yolk in canine freezing extender void of glycerol, a commonly used cryoprotectant, by examining the motility and morphology throughout the freezing process: initial (baseline after extender added), post-cool (after three hours at 5"C) and post-thaw …

The role of yolk syncytial layer and blastoderm movements during gastrulation in zebrafish
… an outer sheet of epithelial cells (EVL) and a yolk syncytial layer (YSL). Epiboly is characterized by the spreading of the blastoderm (deep cells and EVL) to cover the large yolk cell, whereas convergence and extension leads, respectively, to mediolateral narrowing and anteroposterior …

Analysis of Mouse EKLF/KLF2 E9.5 Double Knockout: Yolk Sac Morphology and Embryonic Erythroid Maturation
… Using light and electron microscopy, the yolk sacs and dorsal aortae from EKLF/KLF2 double knockout (KO) E9.5 (embryonic day 9.5) were examined to determine whether these KLFs have compensatory functions in morphology of blood cells and vessels. EKLF/KLF2 double KO E9.5 erythroid, …
