The correct name of the neotropical soybean bug (Hemiptera: Alydidae).

A species of Neomegalotomus is an occasional pest of soybean [Glycine max (L.) Merrill] in the neotropics, including in Brazil. It was known as Neomegalotomus parvus (Westwood); but the discovery of the type specimen of a species described earlier requires that the name be changed to Neomegalotomus simplex (Westwood), which becomes the correct name for the soybean pest.

Expression and distribution of parotid secretory proteins in experimental diabetes.

Previous studies of experimental diabetes have demonstrated changes in the levels of specific salivary proteins. The present study is part of a larger effort aimed at elucidating the mechanism(s) by which insulin regulates salivary protein expression in the rat parotid gland. Diabetes was induced in 2-3-month-old male Fischer 344 rats by injection of streptozotocin (STZ).

The critical micelle condition revisited.

Several simple alternatives have been examined as a possible basis for micellar size distributions which are internally consistent with the experimentally required concept of a threshold concentration, the critical micelle condition. Among these are the two-state system, monomer in equilibrium with a single high polymer, indefinite self-association, and continuous self-association with an arbitrary upper limit beyond which all further association is absolutely prohibited. Of these, only the last is a possible choice, although lacking experimental support.
