The cyst wall of Entamoeba invadens (Ei), a model for the human pathogen Entamoeba histolytica, is composed of fibrils of chitin and three chitin-binding lectins called Jacob, Jessie3, and chitinase. Here we show chitin, which was detected with wheat germ agglutinin, is made in secretory vesicles prior to its deposition on the surface of encysting Ei. Jacob lectins, which have tandemly arrayed ...

An investigation was conducted on the adsorption of oxymatrine (OMT) on a spherical cellulose adsorbent embedded with wattle bark tannin. The results showed that the adsorption of the OMT on the adsorbent was solution pH dependent and the adsorption process followed the Freundlich adsorption isotherm. The adsorption kinetics of the OMT on the adsorbent could be well described by the pseudo-seco...

introduced into the United States, and black wattle (Acacia mearnsii), a species native to Australia that was introduced to South Africa. In response to criticism from environmental and natural resource conservation communities (e.g., Olson and Knopf 19867), many US federal agencies and nongovernmental organizations turned from nonindigenous species to species native to North America for use in...

The aim of this note is to inform the interested reader about the possibility of obtaining several new fonts: Croatian Glagolitic (round – sometimes called Bulgarian glagolitic, angular, Baška tablet, cursive, ligatures, the Baromić broken ligatures, calligraphic), Croatian Cyrillic, stećak ornaments and Croatian wattle patterns. They represent a considerable extension of the first version of G...
