Both the Kjeldahl and the Dumas methods for the determination of protein in foodstuffs are currently in use, but the empirical nitrogen factors used to convert the determined nitrogen content to protein content are based on the Kjeldahl method alone.
Dye tracers were chosen, based on net charge, chemical structure, and reactive groups, to test for the existence of and to provide novel insight into channel selectivities of junctional pathways connecting smooth muscle and endothelial cells of the arteriolar wall.

The alpha-helical coiled-coil tropomyosin homodimer, alpha alphaTm, unfolds cooperatively with T1/2 = 47 degreesC, at neutral pH, 0.5 M NaCl. At pH 2, where each chain contains 55 positive charges, no cooperative unfolding occurs to at least 80 degreesC. The
A dual modification procedure composed of cross-linking and protein coating with K(2)SO(4) was employed to modify Geotrichum sp. lipase for catalyzing biodiesel production from waste cooking oil. Compared to single modification of protein coating with K(2)SO(4), the dual modification of

Local drug delivery has substantial potential to prevent infections compared with systemic delivery. Although calcium sulfate (CaSO(4)) has been studied for local drug delivery and two types are commercially available, it is unknown whether they differentially release antibiotics. We determined
