This report was developed to address institutional biosafety committees' implementation of federal guidelines applicable to the environmental release of genetically engineered organisms. These committees are from universities, companies, and other organizations that are using recombinant DNA technology in their laboratories. The committees are…

Objective: To test for gene-environment interaction with depressive symptoms and family conflict. Specifically, to first examine whether the influence of family conflict in predicting depressive symptoms is increased in individuals at genetic risk of depression. Second, to test whether the genetic component of variance in depressive symptoms…

This booklet, one of six in the Living Things Science series, presents activities about heredity and genetics which address basic "Benchmarks" suggested by the American Association for the Advancement of Science for the Living Environment for grades 3-5. Contents include background information, vocabulary (in English and Spanish),…

Nine hundred and twenty-eight citations in English and foreign languages for the period January 1986 through April 1992 were included. For journal articles written in a foreign…

The hazards posed by new techniques of genetic manipulation have prompted scientists to regulate and in some cases restrict their own basic investigations. Describes some possible applications of the new techniques and outlines the established research guidelines. (GS)

This fact sheet summarizes the interrelations of Down syndrome and Alzheimer disease in a question and answer format. The following questions are addressed: What is Alzheimer disease? Why is a relationship suggested between Down syndrome and Alzheimer disease? Is there a genetic link between Alzheimer disease and Down syndrome? Why is a…

In an attempt to accommodate each of two perspectives (nature versus nurture) in the formulation of a developmental framework, two complementary approaches to developmental theory are presented. First, consideration is given to what is now known about the developmental process in general (thought out in terms of the question "Where is the…

In an attempt to improve the identification of the asymptomatic carrier of classic phenylketonuria (PKU) 59 male and female normal control Ss were differentiated from 18 males and females heterozgous for PKU. (DB)

Reports that as a result of our increasing knowledge of the molecular biology of nitrogen fixation it might eventually be possible to increase the biological production of nitrogenous fertilizer from atmospheric nitrogen. (GS)
