sub-cellular fraction, rather than...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in

The standard way of representing numbers on computers gives rise to errors
which increase as computations progress. Using p-adic valuations can reduce
error accumulation. Valuation theory tells us that p-adic and standard valuations
cannot be directly compared. The p-adic valuation can, however, be used in
an indirect way. This gives...
