The aim of this paper was to evaluate the effects of pH, heat, and Ca ions on the -amylase activities in a commercial amylolytic enzyme (Tyazyme L300), used for apple juice processing. Kinetics of thermal inactivation was studied in acetate and citrate/phosphate buffers at different temperatures (55–70 °C) and enzyme concentrations (0.276 and 0.552 mL/100 mL). Maximum -amylase activity was obse...

A family of Ce-doped LaCoO 3 perovskites are presented as possible catalysts for Cl–VOCs elimination. These materials with different contents Ce were obtained through the citrate and reactive grinding methods. The insertion in original perovskite structure favours presence Co 2+ /Co 3+ /Ce 4+ redox pairs a higher content oxygen vacancies that enhances catalytic performance chlorobenzene combust...

Bayliss, Berenice G. (Washington State University, Pullman), and Elizabeth R. Hall. Plasma coagulation by organisms other than Staphylococcus aureus. J. Bacteriol. 89:101-105. 1965.-Approximately 200 organisms were investigated for their ability to clot human and rabbit plasma. Various anticoagulants were used in preparing the plasma: acid-citrate-dextrose, ethylenediaminetetraacetate, balanced...

Regional citrate anticoagulation (RCA) is a valid anticoagulation method in continuous renal replacement therapies (CRRT) and different combination of citrate and CRRT solutions can affect acid-base balance. Regardless of the anticoagulation protocol, hypophosphatemia occurs frequently in CRRT. In this case report, we evaluated safety and effects on acid-base balance of a new RCA- continuous ve...

background: polycystic ovary syndrome (pcos) is associated with approximately 75% of women who suffer from infertility due to anovulation. additionally, around 20– 25% of anovulatory women with pcos do not respond at all to clomiphene citrate and are considered to be “clomiphene– resistant”. aromatase inhibitors have been suggested as an alternative treatment to clomiphene as the discrepancy be...
