New research findings about how nerve cells transmit signals are forcing researchers to overhaul their simplistic ideas about the nervous system. Topics highlighted include the multiple role of peptides in the nervous system, receptor molecules, and molecules that form ion channels within membranes. (Author/JN)

Describes 16 mutagens/carcinogens found in plant food and coffee as well as several anticarcinogens also found in such food. Speculates on relevant biochemical mechanisms, particularly the role of oxygen radicals and their inhibitors in the fat/cancer relationship, promotion, anticarcinogenesis, and aging. (JN)

Aerobic training develops efficient catabolic responses in large muscles. (JD)

The paper presents findings from research on megavitamin nutritional therapy with behavior-disordered and learning-disabled children. The results suggest it is a valid biochemical alternative to other means of therapy. Some researchers are concerned about the possibility of poisoning the system and the lack of evidence of long-range effects. (PHR)

Presents a brief review of pesticide use. Included topics are: biological activity, formulation, application, uptake, metabolism, residues, and tolerance. (BB)

Presents a brief review of the chemistry of the plant cell wall. Included topics are: analytical techniques, structure, growth, and maturation. (BB)

Provides a general overview of fluoro-organic biochemistry and illuminates areas where further study is desirable. (BB)
