Chicken egg yolk antibodies as therapeutics in enteric infectious disease: a review.
TLDR
The IgY technology offers great future opportunities for designing prophylactic strategies against infectious GI diseases in humans and animals, but there is still controversy regarding the stability of IgY through the GI tract.Abstract:
Passive immunization by oral administration of specific antibodies has been an attractive approach against gastrointestinal (GI) pathogens in both humans and animals. Recently, laying chickens have attracted considerable attention as an alternative source of antibodies for the prevention and treatment of infectious GI diseases. After immunization, the specific antibodies (called IgY) are transported to the egg yolk, from which the IgY then can be separated without sacrificing chickens. A chicken usually lays about 280 eggs in a year, and egg yolk contains 100-150 mg of IgY per yolk, suggesting that more than 40 g of IgY per year can be obtained from each chicken through eggs. IgY is also an alternative to antibiotics for treatment of enteric antibiotic-resistant pathogens. Oral administration of IgY has proved successful for treatment of a variety of GI infections, such as bovine and human rotaviruses, bovine coronavirus, Yersinia ruckeri, enterotoxigenic Escherichia coli, Salmonella spp., Edwardsiella ta...read more

A 2dvEv- bit distributed algorithm for the directed Euler trail problem
Wen-Huei Chen,Chuan Yi Tang +1 more
TL;DR: The algorithm can be used as a building block for solving other distributed graph problems, and can be slightly modified to run on a strongly-connected diagraph for generating the existent Euler trail or to report that no Euler trails exist.

Three-dimensional structure of rotavirus.
TL;DR: The three-dimensional structures of double and single-shelled simian rotavirus have been determined to a resolution of 40 A by image processing electron micrographs of unstained, unfixed virus particles embedded in vitreous ice and it is demonstrated that the icosahedral surface lattices in these structures have a triangulation number of 13 in a left-handed configuration.
