Abstract: Imidazole compounds including imidazoles and imidazolium salts, and their use as transglutaminase inhibitors are disclosed.

Abstract: A galactose-regulated yeast strain expresses a desired protein in improved yield by growing the transformed yeast cells in culture in fed-batch mode and replacing the culture medium with fresh medium before adding the galactose to induce expression of the foreign protein.

Abstract: Methods of purifying recombinant surface antigen of hepatitis B virus are disclosed. In one protocol, purification is achieved by selective extraction of the antigen from yeast membranes, followed by solubilization with urea and dithiothreitol.

Abstract: A new antifungal agent which exhibits a moderately broad spectrum of activity towards filamentous fungi and also against Cryptococcus species of the yeast fungi, and which has been isolated from a solid stationary fermentation of an unidentified species of Fusarium is described.

Abstract: Enzyme di- or tripeptides of the formula: ##STR1## and analogs thereof which inhibit renin and are useful for treating various forms of renin-associated hypertension, hyperaldosteronism and congestive heart failure; compositions containing these renin-inhibitory peptides, optionally with other antihypertensive agents; and methods of treating hypertension, hyperaldosteronism or congestive heart failure or of establishing renin as a causative factor in these problems which employ these novel peptides.

Abstract: Cement compositions, i.e., mortar, structured concrete, pre-cast concrete, and oilfield cement, comprising 0.01-0.9% (wt/wt) welan gum are described.

Abstract: Methods of antagonizing gastrin and/or cholecystokinin (CCK) with benzodiazepine analogs are disclosed, as well as related pharmaceutical compositions, which are useful in treating disorders of the gastrointestinal tract, central nervous system, and of the appetite.
