Stats indicate that there is a significant increase in protein and copper concentrations of the hemolymph during oocyte maturation, and it is probable that lipovitellin is synthesized external to the ovary and transferred to the oocytes during vitellogenesis. Expand
The hemolymph proteins of the blue crab, Callinectes sapidus. I. Hemocyanins and certain other major protein constituents.
Species specificity of the electrophoretic patterns is confined to the characteristic mobility and dissociation of fast hemocyanin, the only protein found to be present in all samples of blue crab hemolymph. Expand
Width, length and the concentrations of hemolymph protein and copper were determined individually for 333 adult blue crabs, Callinectes sapidus Rathbun, with no correlation between specimen size and mean serum protein or copper concentrations. Expand
Satellite DNAs in Crustacea: Two Different Components with the Same Density in Neutral CsCI Gradients
This work finds at least one and in some instances two DNA satellites in each species and was surprised to discover that two distinctly different satellite DNAs band at the same density, 1.677 g/cm3, in CsC1. Expand
Comparative effect of the thiols dithiothreitol, cysteamine and WR-151326 on survival and on the induction of DNA damage in cultured Chinese hamster ovary cells exposed to gamma-radiation.
All three thiols protected against ssb induction, although to a significantly lower extent than against cell killing measured under identical conditions, and each thiol also protected against dsb induction. Expand
Radioprotection of cultured Chinese hamster ovary cells by WR-255591.
The observation of lower PFs for DNA strand breaks than for cell survival suggests that radioprotection by WR-255591 probably does not result from a uniform decrease in the induction of all types of DNA lesions, rather, the drug may differentially protect againstThe induction of subclasses of DNA damage.

Chromatographic isolation of crustacean hemocyanins
When isolated, concentrated and rechromatographed, hemocyanins were eluted from the columns in positions identical to those in the original separations from other serum proteins. Expand
Behavioural adaptation of the tapeworm Hymenolepis diminuta to its environment.
The data suggest that the peripheral nervous system, and not the central nervoussystem, is responsible for the coordination of the fixed patterns of locomotory activity in these tapeworms. Expand
