Describes an undergraduate laboratory project involving lecithin which integrates two general aspects of lipid methodology: chromatographic techniques and use of enzymes specificity to obtain structural information. (Author/SLH)

Described is thin-layer chromatography (TLC), a technique that can be conveniently used in the laboratory to generate evidence supporting the principle that degrees of biochemical similarity reflect degrees of evolutionary relatedness among organisms. (Author/PEB)

The relationship of bilirubin (a red bile pigment that is sometimes found in the urine and occurs in the blood and tissues in jaundice) in infancy to later intellectual development was investigated in 241 infants with moderately elevated and high bilirubin levels. Ss were administered motor, psycholinguistic, and intelligence tests at age 8…

Presented is a case study of an infant with galactokinase (enzyme) deficiency, resulting in brain pseudotumors and cataracts. (CL)

Presents a series of calculations, appropriate for the freshman level, to determine the flow of electrons to oxygen along the electron transport chain. States that living organisms resemble fuel cells and develops calculations for determining power output. (GS)

Relates occurrences at the Asilomar conference that led to the drafting of guidelines for gene-transplant research. The guidelines allow some experiments, defer others until safer containment is available, and ban those considered highly dangerous. (GS)

This course is intended for personnel who have an operational or administrative responsibility for the design and use of bioassay and biomonitoring, and who have no experience in conducting static bioassays. The training consists of classroom discussions, laboratory exercises and demonstrations, and demonstration and observation activities. (CO)

The paper examines the incidence of minor physical anomalies (MPAs) in 42 normal junior high Ss, 24 kindergarten Ss in a middle class district, 52 status and misdemeanor delinquents, 70 adolescent psychiatric patients, 32 learning disabled children, and 10 autistic children. MPAs included facial asymmetry, epicanthal folds, and geographical or…

This study investigated (1) the nutritional status of urban American disadvantaged children, (2) the relationship of nutritional status to mental growth and development, (3) the relationship of physical maturation to the development of perceptual-motor factors of intelligence, and (4) if found, the effects of undernutrition on intellectual…

At each meeting of the Pan American Health Organization Advisory Committee on Medical Research, a special 1-day session is held on a topic chosen by the committee as being of particular interest. At the 7th meeting, which convened in June of 1968 in Washington, D.C., the session surveyed the origin, present distribution, and principal biological…

Performance objectives are stated for each of the secondary school units included in this package of instructional guides prepared for the Dade County Florida Quinmester Program. All three units are concerned with chemistry: "Applied Chemistry 1,""Chemistry of Biology," and "Matter and Its Changes." The last unit…
