teins on the tumor cells was shown to be specific, pH de pendent, and concentration dependent. Native ricin, abrin, D-galactose, and its sterically related saccharides inhibit this specific binding, while concanavalin A, bovine serum albumin, heat-denatured abrin or ricin, and other sac charides do not. In the presence of D-galactose, the inhibi tion of protein biosynthesis by ricin does not oc...

Leymus chinensis and Leymus secalinus are perennial rhizome grasses; photosynthetic physiological characteristics were compared between them in Sandy and Saline-Alkaline Soils on the Songnen Plains of China. The contents of chlorophyll and soluble saccharides were positively correlated with photosynthetic characteristics. The photosynthetic capacity of L. chinensis was significantly greater tha...

Gas chromatography/mass spectrometry (GC/MS) of the MOD flake Micro-samples (3.3 mg from the MOD flake and less than 1 mg from the other samples, see below) were collected from the specimens and submitted to an analytical procedure (GC/MS) in order to identify lipids, waxes, proteins, resinous materials and saccharides [1-2]. GC/MS had already been successfully employed for the characterization...
