Provides a broad overview of the major natural removal mechanisms that occur in the environment, including chemical transformations, biological degradation, and physical processes. (Author/BB)

This test measures the capability of a chemical substance to cause mutations in special strains of the bacterium Salmonella. It is quick, taking only forty-eight hours, inexpensive, and reliable. (BB)

Describes some laboratory exercises using the mole crab, Emerita talpoida, as an experimental animal for the study of osmoregulation. (GA)

A computer program is described for identification of chiral centers in molecules. Essential input to the program includes both atomic and bonding information. The program does not require computer graphic input-output. (BB)

The broad area of biochemistry is surveyed. Subtopics include nuclei acids, peptide hormones, cell surfaces, and enzymology. (MDR)

Using theoretical calculations and computer programs, some organic chemists are able to make detailed descriptions of reactions without relying on experiments. (MA)

This is a review of the relationship of neurochemistry to behavior. Most of the common neurotransmitters and neuromodulators are introduced. Special emphasis is given to the involvement of neurochemistry in mental disorders. (BB)

This is a review of the pharmacological treatment of mental illnesses. Included topics are: schizophrenia, depression, mania, antipsychotic drugs, antidepressants, lithium, and ethics. (BB)

Discusses dichlorodiammineplatinum's ability to inhibit bacterial cell divisions and its use as an antitumor agent. (SL)

In eighteen chronic schizophrenics, subcutaneous doses of the dopamine reception agonist, apomorphine, improved psychotic symptoms. The results are interpreted as a consequence of presynaptic dopamine receptor activationby apomorphine with a subsequent decrease in dopamine-mediated neural transmission. (Author/BB)

Describes some of the chemical compounds involved in the nervous system and their roles in transmitting nerve signals. Discusses acetylcholine, dopamine, norepinephrine, serotonin, histamine, glycine, glutemate, and gamma-aminobutyric acid and their effects within the nervous system. (CW)

Discusses some of the problems associated with teaching abstract concepts in biochemistry because of the inability to provide visual aids. Suggests the use of metabolonograms as analogies in teaching certain concepts. (TW)

Provides an overview on biological electron-transfer reactions, summarizing what is known about how distance, spatial organization, medium, and other factors affect electron transfer. Experimental approaches, including studies of bimolecular electron transfer reactions (electrostatic effects and precursor complexes), are considered. (JN)

Discusses: (l) alkali and alkaline-earth cations in biology (considering naturally occurring lonophores, their X-ray structures, and physiochemical studies); (2) synthetic complexing agents for groups IA and IIA; and (3) ion transport across membranes (examining neutral macrobicyclic ligands as metal cation carriers, transport by anionic carriers,…

Argues that the sociobiological argument (i.e., that suicide is associated with reduced reproductive potential) seems to have little explanatory value and to misrepresent the variability in cross-cultural patterning of suicidal behavior. Proposes a biocultural theory of suicide which addresses both the specific situational stressors and the…
