Background: Although it is well known that exercise affects various immune functions, it remains to be determined whether exercise influences change in the mucosal immunity of elderly people. The objective of the present study is to examine whether l

1. 1. A similar high molecular weight glycoprotein is found in an asteroid egg, Pisaster giganteus , and in echinoid eggs, Dendraster excentricus and Strongylocentrotus purpuratus . 2. 2. Estrogen induced the synthesis of a novel protein in echinoid

The two molecular forms of acethylcholinesterase (EC 3.1.1.7) in sea urchin embryos were characterized by several physical methods. The sedimentation coefficients determined by sucrose gradient centrifugation are 7.6S and 10.6S. The Stokes radii dete

Acetylcholinesterase during the development of the sea urchin Pseudocentrotus depressus was examined by enzyme assay (the colorimetric method of Ellmanet al.), histochemistry (a Cu-thiocholine method), polyacrylamide gel electrophoresis and DEAE-Seph

l -Malate dehydrogenase ( l -malate:NAD oxidoreductase EC 1.1.1.37) of the sea urchin Strongylocentrotus purpuratus occurs in two forms. One form is shown to be localized in mitochondria of this species. The other form occurs exclusively in the cytop

Histones have been isolated from the nuclei of unfertilized eggs of the sea urchin Strongylocentrotus purpuratus . The electrophoresis of these histones exhibits a pattern different from that of the sperm or embryo of the same species.

Isolated chromatin of the sea urchin embryo supports RNA synthesis catalyzed by exogenous RNA polymerase. Such chromatin-primed RNA synthesis possesses the general characteristics known for DNA-dependent RNA synthesis. Pluteus chromatin is more activ

1. Tests were made of the uptake and incorporation into protein of a neutral (C14-valine), an acidic (C14-glutamic acid) and a basic(C14-arginine) amino acid in the presence of a mixture of other amino acids and in the presence of a great excess (300

Chromatin was isolated from spermatozoa of the sea urchin Strongylocentrotus purpuratus. The isolated chromatin shows less absorptivity ratio of 230 nm : 260 nm and possesses less protein than does embryonic chromatin. The ratio of histone : DNA is 1
