Immobilized enzymes: Electrokinetic effects on reaction rates in a porous mediumdoi:10.1002/bit.260241106The effect of the internal diffusion and electrical surface charge on the overall rate of a reaction catalyzed by an enzyme immobilized on a porous medium are examined. Effectiveness factors have ...
Isozyme patterns of enzymes in the red cells and serum of the patients and their parents were also examined. The first case, a boy with multiple anomaly was 7 months old. Chromosome constitu- tion of the patient was 46,XY,del(4) (p15). However, his parents had apparently normal ...
neural mechanism underlying the phenomenon in rats with constrictive ligatures placed loosely around thesciatic nerve. In 2002 Chinese-born neuroscientist Min Zhuo and colleagues reported the identification of two enzymes, adenylyl cyclase types 1 and 8, in the forebrains of mice that play an ...
Changes in the hydrodynamic volume are promoted by modulation of chemical equilibria that would alter the relative abundance of enzymes that exist in different conformations, shifting the equilibrium between these conformations4, 39. In the presence of crowding agents, there appears to be positive ...
It has been known for many years that rates of oxygen isotope exchange between water and both aqueous and solid phosphate are negligible at low (surface) temperatures in the absence of appropriate enzymes Tudge 1960, Boyer 1978, Blake et al 1997. Rates of exchange increase rapidly with ...
Also, fish exposed acutely to unweathered crude oil had an increased prevalence of lipid vacuole accumulation in the cardiac muscle (Hook et al., 2018) although it is not clear whether this was due to the reduced activity of enzymes involved in fatty acid metabolism or an increase in ...
Lipid metabolism is intricately linked to the onset and progression of ferroptosis. Polyunsaturated fatty acids (PUFAs) possess bis-allylic hydrogen atoms that are readily abstracted, rendering them susceptible to lipid peroxidation. Key enzymes involved in lipid metabolism, such as arachidonic acid lipox...
First, in the process of dispersing nanoparticles in wood, nanoscale metals may interact with bacteria, causing bacteria to die or deactivate the enzymes required for the degradation reactions [137]. In this process, the degree of interaction between the metal and the wood matrix should be ...

On the other hand, IL-6 is a signaling molecule that can be secreted by various cells of the body including monocytes/macrophages, lymphocytes, and epithelial cells39. Additionally, MMP-9 belongs to the Zinc-bound metalloprotease family of enzymes, which mainly participate in the inflammation ...
