The role of organic factors in childhood hyperkinesis is evaluated, with a review of research on electroencephalographic, neurological, biochemical, pregnancy and birth, and genetic factors. (DB)

Describes undergraduate experiments concerning three topics: oxygen carriers, nitrogen fixation, and metal activated enzymes. (MLH)

Presents three activities: (1) the investigation of the purity and stability of nicotinamide and flavin coenzymes; (2) desk-computer fitting of a two-exponential function; and (3) an interesting and inexpensive solubility product experiment for introductory chemistry. (RH)

Describes an experiment which quantitatively determines glucose by a spectrophotometric measurement of the colored complex formed between glucose and an amine. (MLH)

Reports on a study in which high school biology students were divided into two groups: one read "Scientific American" articles and the other group read annotated "Scientific American" articles. Although there was no significant difference between means on an achievement measure of the groups, the author reports that students…

Describes an undergraduate experiment that illustrates the use of thin-layer chromatography. (MLH)

Two specialized facilities to produce cells and cell components on a large scale for scientific research have recently been established by the National Science Foundation. (BB)

The metabolism and toxicology of the herbicide 2, 4, 5-T are reviewed. (BB)

Describes the applied science course at Kingston Polytechnic, its requirements, the background of students enrolled in it, and the breadth of its offerings. (GA)

Discusses the kinetic behavior associated with the interaction of metal ions with apocarbonic anhydrase, focusing on the formation of two metallocarbonic anhydrase--the biochemically active Co(II) and the inactive Ni(II)derivatives. (GA)

Describes a simple inexpensive experiment designed to measure the levels of cortisol in a serum or plasma sample. (Author/GA)

Describes several activities that can be done with laboratory mice to study the physiological role of oxytocin. Diagrams included. (MA)

Describes an interdisciplinary program in the areas of biochemistry, biology, and computer science offered at Chestnut Hill College, Philadelphia, Pennsylvania, to update 30 women in order to prepare them to return to the job market in chemistry. (HM)

Presents a biochemistry experiment for college students that illustrates the purification of an enzyme. (HM)

The historical development of the use of diphosphonates in detergents is presented as well as physical chemistry, physiological response, toxicology, and human clinical trials with these compounds. (BB)
