Reactivity Control

In BWR’s steam bubbles have a negative steam bubbles have a negative reactivity feedback, if the steam fraction reactivity feedback, if the steam fraction increases in the core the reactor power increases in the core the reactor power decreases

There is still a controversy over the mechanism of promoter DNA strand separation upon open transcription complex (RPo) formation by Escheri-chia coli RNA polymerase: is it a single or a stepwise process controlled by Mg 2+ ions and temperature? To resolve this question, the kinetics of pseudo-first-order oxidation of thymine residues by KMnO4 in the )11…+2 DNA region of RPo at thekPRpromoter was examined under single-hit conditions as a function of temperature (13–37
C) in the absence or presence of 10 mmMgCl2....

Cys34 in domain I of the three-domain serum protein albumin is the bind-ing site for a wide variety of biologically and clinically important small molecules, provides antioxidant activity, and constitutes the largest portion of free thiol in blood. Analysis of X-ray structures of albumin reveals that the loop containing Tyr84 occurs in multiple conformations. In structures where the loop is well defined, there appears to be an H-bond between the OH of Tyr84 and the sulfur of Cys34.

Inhibition of the mitochondrial adenine nucleotide translocator (ANT) by long-chain acyl-CoA esters has been proposed to contribute to cellular dys-function in obesity and type 2 diabetes by increasing formation of reactive oxygen species and adenosine via effects on the coenzyme Q redox state, mitochondrial membrane potential (Dw) and cytosolic ATP concentrations.

Peroxiredoxin V (PRDX5) is a member of the family of mammalian pro-teins that neutralize reactive oxygen species. The PRDX5gene is constitu-tively expressed at a high level in many human tissues, but functional elements of its promoter responsible for a high basal activity in the absence of oxidative stress have still not been identified.

Ig-like transcript 2 (ILT2) is a suppressive receptor that participates in the control of the autoimmune reactivity. This action is usually carried out in a proinflammatory microenvironment where there is a high production of free radicals and NO.
