Hydrolytic and synthetic activities of mitochondrial ATPase were studied during (+/-)-isoproterenol-induced cell injury of the myocardium (67 mg/kg body weight). This research was a long-term study (72 h) in which rat heart homogenates, and a potentiometric method were used. Hydrolytic activities in homogenates from (+/-)-isoproterenol-treated rats were not statistically different, during the w...

Polygalacturonases (PGases) or hydrolytic depolymerases are enzymes involved in the degradation of pectic substances. They have a wide range of applications in food and textile processing, degumming of plant rough fibres and treatment of pectic wastewaters. Bacteria, yeasts and fungi under both submerged (SmF) and solid-state fermentation (SSF) conditions produce these enzymes. Bacteria produce...

The production of hydrolytic enzymes from external mycelia associated with roots and colonized soybean roots (Glycine max L.) inoculated with different arbuscular-mycorrhizal (AM) fungi of the genus GLOMUS:, and the possible relationship between these activities and the capacity of the AM fungi to colonize plant roots was studied. There were differences in root colonization and plant growth bet...

Multifunctional vinyl sulfonates and vinyl sulfonamides were conveniently synthesized and assessed in thiol-Michael crosslinking polymerizations. The monomer reactivities, mechanical behavior and hydrolytic properties were analyzed and compared with those of analogous thiol-acrylate polymerizations. Materials with a broad range of mechanical properties and diverse hydrolytic stabilities were ob...

We introduce two generalized condensation principles: Local Club Condensation and Stationary Condensation. We show that while Strong Condensation (a generalized Condensation principle introduced by Hugh Woodin in [19]) is inconsistent with an ω1-Erdős cardinal, Stationary Condensation and Local Club Condensation (which should be thought of as weakenings of Strong Condensation) are both consiste...
