Biological Background

For a communication between neurons to occur the sender must release substances to excite a receiver and modify its inner potential if this potential reaches a threshold then an electrical impulse of fixed strength and duration known as action potential is released and travels down the axon to the synapses with other neurons. 

Action potentials are the signals by which the brain receives, analyzes and carries information they are the response of the neurons to many inputs. The information carried by an action potential is determined not by the form of the signal but by the pathway the signal travels in the brain (Kandel et al.2000).

As has been noted, much of the interest in hlms of proteins, steroids, lipids, and so on, has a biological background. While studies at the air-water interface have been instructive, the natural systems approximate more closely to a water-oil interface. A fair amount of work has therefore been reported for such interfaces in spite of the greater experimental difhculties.

We have included introductory chapters to enable readers who come from a more biological background to understand the notions of inorganic chemistry, and vice versa to explain chemists the important notions of structural and molecular biology, which will be necessary to follow our path through the diverse roles of metals in biological systems. 

Abstract This review presents a wide-ranging selection of key literature examples in the histone deacetylase (HDAC) field. The review starts off with the biological background... 

The use of multivariate spectral information is particularly advantageous where quantification of a particular metabolite in a complex biological background is being attempted and application of the technique necessitates the use of chemometric processing techniques for quantification of components. 

Clearly, toxicology is a vast and complex subject, overlapping with several other disciplines.1 23 A full and detailed account of this branch of science would take many volumes, but some aspects of relevance to this review are discussed to provide some biological background one example is the role of the cytochromes P450 in metabolism, detoxication, and carcinogenesis.
