e.g. uricase and d-amino-acid oxidase and their respective substrates, in other words systems which react directly with molecular 02 and reduce it to H202. The increased 02 uptake was shown to be due to the secondary oxidation of ethanol to acetaldehyde by H202 formed in the primary oxidation reaction. It was a matter for some surprise to find that this secondary oxidation of ethanol took place...

We report here the preparation of an immobilized-enzyme nylon-tube reactor containing uricase (EC 1.7.3.3) and the assembly of a flow-through system (Technicon AutoAnalyzer II) for the routine determination of uric acid in serum. Results of these uric acid analyses by use of immobilized uricase, in conjunction with peroxidase (EC 1.11.1.7) and aminophenazone-dichlorophenol in solution, are comp...

Venetoclax along with hypomethylating agents (HMAs) is the new standard therapy for older patients acute myeloid leukemia (AML) not fit intensive frontline induction chemotherapy. associated fatal episodes of tumor lysis syndrome (TLS) in chronic lymphocytic (CLL), and recommendations are its initiation CLL AML inpatient setting close monitoring. Herein, we evaluated safety outpatient venetocla...

our findings is that the concentration of HC is influenced by the vitamin B12 status of the patient. The issue has important implications for the interpretation of low cobalamin in relation to low HC concentrations in patients undergoing examination for vitamin B12 deficiency. If genetic factors were the only regulators of the HC concentration, the physician could decide that the low concentrat...

Glutathione,ascorbicacidand many commonly used antibiotics falsely elevate uric acid concentrations when measured with the Du Pont “aca,” in which the copper-chelate method is used. L-Dopa interferes with both the copper-chelate method and the Technicon “SMA 12/60” phosphotungstate method. A new kinetic uricase method has been developed for use on the Du Pont aca. This kinetic uricase method ha...

Research on birds has long played an important role in ecological investigations, as birds are relatively easily observed, and their high metabolic rates and diurnal habits make them quite evidently responsive to changes in their environments. A mechanistic understanding of such avian responses requires a better understanding of how variation in physiological state conditions avian behavior and...

A method and a device for the promotion of crystal growth by keeping the crystallization solution metastable during the growth process are described. This is achieved by controlled temperature variation of the crystallization solution using parameters determined in situ during the growth process. The technique finds application in the growth of large high-quality crystals for neutron crystallog...
