The paper refutes the long held belief that Down's syndrome is the result of maternal age and maternal etiology. The author cites new evidence which demonstrates that Trisomy-21 (the presence in the chromosome of an extra arcocentric chromosome resulting from non-disjunction), the major cause (95% of the cases) of Down's syndrome, can originate in…

The paper considers the future of education, particularly special education, in terms of theory. Reviewed is research in neurology relating to contra-lateral development in brain hemispheres, cephalo-caudal and caudal-cephalo myelination patterns or neural systems, and integration of neural patterns and neo-cortical control of the brain. Also…

This speech offers a brief description of Huntington's Disease (HD): its causes, symptoms, and incidence. It then concentrates on the psychological problems of persons one of whose parents had the disease, and the role of the counselor in helping these humans cope with their fears about contacting it themselves.

Investigated were the feasibility and effectiveness of using programed materials with concomitant laboratory exercises in teaching genetics on the secondary level. Students from two white and two Negro high schools in the Atlantic Public School System participated, with one control and one experimental biology class in each school taught by the…

Material is discussed in articles by 40 contributors. Concerning physiopathogenesis of epilepsies there are introductory notes, two articles on genetics, one on neurophysiological and metabolic mechanisms, two on renal failure, a discussion of convulsive seizure and water intoxication, three articles on hypoglycemia, one on electroclinical…

The pamphlet, written for physicians and other health professionals who counsel parents, explain five factors which put women at high risk of giving birth to a child with Down's Syndrome and three antenatal diagnostic techniques.

Presents a simple pedagogical model to teach the importance of antiparallel complementarity in nucleotide pairing when replication, transcription and coding are initially introduced. (HM)

Presents an attempt to explore plant chimeras and to demonstrate the separation of genetically distinct tissue in a chimera using an easily grown scented geranium plant. (HM)

The article explains diabetes mellitus, giving a brief history of the disease, its description, complications, and treatment. (PHR)
