VENEZUELAN EQUINE ENCEPHALOMYELITIS.
The VEE complex of viruses includes six antigenic subtypes (I–VI). Within subtype I there are five antigenic variants (variants AB–F). Originally, subtypes I-A and I-B were considered to be distinctExpand
The biochemistry of animal fossils
Electron Micrography of the Virus of Influenza
TLDR
The recognized elementary bodies of influenza are spherical with diameters of 80–100 millimicrons, but the presence of elongated forms that have the diameter of the spheres and frequently appear partly segmented into them is indicated. Expand
The Structure of Crystals
DR. WYCKOFF'S monograph on “The Structure of Crystals” has, in the second edition, been revised so drastically that it is in effect a new book, since, although the experience gained from the firstExpand
COLLAGEN IN FOSSIL TEETH AND BONES.
TLDR
Electron micrographs made before and after decalcification ofUltrathin sections from fossil teeth and bones show the collagen and other organic matter they contain and suggest the way it may alter with time. Expand
The electron microscopy of macromolecular crystals
A survey is given of recent applications of electron microscopy to the direct study of the molecular structure of macromolecular solids. The arrangement of molecules in a number of proteins is shownExpand
The electron microscopy of F-actin
Abstract Electron micrographs have been made of deposits of F-actin polymerized in situ from the globulin form. Aggregates of fibers obtained in this way show a new cross segmentation and lateralExpand
THE AMINO ACID COMPOSITION OF PROTEINS FROM PLEISTOCENE BONES.
TLDR
Complete amino acid analyses have been made of proteins persisting in three pleistocene bones from the Rancho La Brea tar pits and in a recent desert-dried boned used as control, pointing to the presence of other proteins besides the collagen the electron microscope shows to be present. Expand
THE KILLING OF COLON BACILLI BY ULTRAVIOLET LIGHT
  • R. Wyckoff
  • Physics, Medicine
  • The Journal of general physiology
  • 20 January 1932
TLDR
The survival ratios of colon bacilli subjected to several monochromatic ultraviolet radiations follow semilogarithmic straight lines, indicating that though bacterial death should result from a single quantum absorption, millions more such absorptions seemingly are without injurious effect on cell growth and multiplication.
