Degradation of phenylalanine:pyruvate transaminase after glucagon treatment

Biochimica et Biophysica Acta (BBA) - Enzymology, 1978
Using a single-isotope and immune precipitation technique the half-life (t 1/2) of hepatic phenylalanine:pyruvate transaminase (aminotransferase, EC 2.6.1.--, Number not yet assigned) from glucagon-treated rats was determined to be 2.8 days, similar to that of the control rats (t 1/2 = 3.3 days).

Kinetic Treatments of Degradation

1996
Most photodegradation experiments are usually carried out in isothermal conditions, whereas polymers and plastics work in the environmental conditions within non-isothermal parameters. The rates of many degradation processes in polymers generally increase as the temperature rises.

Degradation of Chloroacetanilide Herbicides by Anodic Fenton Treatment

Journal of Agricultural and Food Chemistry, 2006
Anodic Fenton treatment (AFT) is an electrochemical treatment employing the Fenton reaction for the generation of hydroxyl radicals, strong oxidants that can degrade organic compounds via hydrogen abstraction. AFT has potential use for the remediation of aqueous pesticide waste.

Sequential degradation of chlorophenols by photolytic and microbial treatment

Environmental Science & Technology, 1988
Using the radiolabeled model pollutants 2,4-dichlorophenol (DCP) and 2,4,5-trichlorophenol (TCP) the authors demonstrated that the brief UV (300-nm) photolysis greatly facilitates the removal of the two chlorophenols from sewage through accelerated mineralization and binding of polar products. The addition of 0.1 M H/sub 2/O/sub 2/ strongly accelerated

Dioxins degradation and reformation during mechanochemical treatment

Chemosphere, 2017
Mechanochemical dechlorination and destruction of polychlorinated dibenzo-p-dioxins and -furans (PCDD/F) on fly ash from Municipal Solid Waste Incineration was tested with and without additives (CaO and CaO/aluminium powder). The first results disappointed because of obvious PCDD/F-reformation and a second test series was conducted after removing ...

A Degradable Macromolecular Antioxidant for Efficient Arthritis Treatment

Biomacromolecules
Reactive oxygen species (ROS) are vital but harmful in excess, and numerous small molecule antioxidants (e.g., polyphenols) can help to maintain an optimal ROS balance. Considering factors like biocompatibility, it is more commonly preferred to transform these natural antioxidants into nanoscavengers through a macromolecular engineering strategy ...

Surface Degradation and Protective Treatments

1981
The environmental conditions under which various materials are required to operate in the compressor and turbine section of gas turbines are briefly discussed. Most attention is given to materials and environmental degradation problems encountered in aero engines, with brief reference to components used in marine and industrial engines where the ...
