Discusses research on the structures of metalloproteins and the role of iron in biological transport systems. (MLH)

Briefly reviewed are clinical studies of serotonin 5-hydroxytryptamine (5-HT) and its metabolites in children with central nervous system diseases which affect brain function. (Author/MC)

The Keller Method requires abolishing lectures as a vehicle of information transfer in favor of a study guide and breaking the biochemistry course into a number of units each to be mastered at the student's own pace. (Editor)

Discusses the scope, present development, course offerings, and manpower utilization in the field of biochemistry. Indicates that the study of the subject is an intellectual challenge with unlimited opportunities. (CC)

In this second article on thin layer chromatography six kinds of experiments are suggested for science teachers to use in schools. (PS)

Describes a three-hour experiment designed to introduce students to chemistry of the angiotensis-converting enzyme, illustrate design of a quenched fluorescence substrate, and examine considerations necessary in designing a clinical assay. Includes background information on the biochemistry of hypertension, reagents/materials needed, procedures…

Suggesting that the evolutionary record may be written in proteins and genes, discusses research in which species are compared by immunology, DNA, and radioimmunoassay. Molecular studies show that DNA from humans and chimps is 98 percent identical, a degree of similarity usually occurring only among animals of the same genus. (JN)

Discusses topics on membrane electrodes corresponding to approximately six hours of lecture time. These include glass, liquid, crystal, gas-sensing membrane electrodes as well as enzyme and other bioselective membrane electrodes. Instructional strategies and other topics which might be discussed are provided. (JN)

Using ascorbic acid enzyme assays in conjunction with chronoamperometric measurements, reliable values for the principal electroactive components in the rat caudate extracellular fluid were established. Techniques used in the study are discussed. (JN)
