    Notes: Glucoamylase was immobilized to porous silica and its kinetics and stability were observed with acid- and α-amylase-hydrolyzed dextrin as feed. The enzyme was found to be extremely stable in both laboratory and pilot plant operations. When the feed had been previously only lightly hydrolyzed, pore diffusion limitation caused appreciable decreases in glucose production rate. The severity of starch hydrolysis to dextrin markedly affected ultimate glucose yields. The diffusional gradients present in the carrier pores caused the immobilized enzyme to yield lower glucose concentrations than the free enzyme at similar feed conditions.

    Notes: Two mixed immobilized enzyme systems, glucoamylase-glucose isomerase and glucose isomerase-glucose oxidase-catalase, were operated to verify theoretical predictions that optimal bifunctional catalyst configutations could exist superior to those where the catalysts were mixed uniformly or arranged sequentially in a tubular reactor. The experimental results for all three configurations conformed to the theoretical values sufficiently closely to support of optimal catalyst profiles.

    Cellular and subcellular localization of 3H-diethylstilboestrol in the central nervous system (1977)

    Notes: Summary The cellular and subcellular localization of radioactivity in the brain of immature female rats was determined by dry-mount autoradiography 2 h after iv injection of 1.0 μg of (monethyl-3H) diethylstilboestrol per 100 g body weight. A specific topographic pattern of nuclear concentration of the synthetic oestrogen was obtained similar to that for 3H-oestradiol-17β in specific neurons of the basal hypothalamus, preoptic region and amygdala. In competition experiments, the nuclear concentration of radioactivity in all areas studied was inhibited by unlabeled oestradiol, while unlabeled testosterone had no effect. These data suggest that although oestradiol can bind to androgen receptors, the oestrogen receptor itself can account for the localization seen after the injection of 3H-oestradiol.
