Qualitative aspects of protein synthesis in organelles and intact cultured cells of brain origin were compared to clarify the distinction between synaptosomal and mitochondrial protein synthesis. Brain mitochondria and synaptosomes were isolated either on a traditional Ficoll-sucrose gradient or by a new Percoll gradient procedure, and were incubated in an(More)
OBJECTIVE To examine swimming ability and variables associated with swimming for US inner-city, minority children. Empirical research on minority children's swimming ability is non-existent, and drowning rates for this population are high. DESIGN Cross-sectional survey research. Descriptive statistics were produced. Multiple regression was applied using(More)
Individual gangliosides were extracted and quantified from intact and subregionally dissected hippocampal formations during the first 3 weeks of postnatal development in the rat. The 4 major gangliosides were all found to be rapidly increasing relative to brain weight prior to the onset of significant synaptogenesis, but quantitative changes in the final(More)
Analysis of deoxyribonucleic acid (DNA) from four species of Clostridium, including two thermophiles, a mesophile, and a psychrophile, revealed no obvious relationship between growth temperature and DNA base composition. The melting temperatures (T(m)) of the DNA from the four species varied no more among the thermophilic, mesophilic, and psychrophilic(More)
1. Ganglioside patterns were analyzed from four neural tissues (medulla, midbrain, forebrain and retina) in a representative from each of the four tetrapod classes. 2. Regional variations in ganglioside patterns were noted within some species, but differences were greater across phylogenetic lines. 3. These results suggest that evolutionary history plays a(More)
Mitochondria were isolated from a slow-growing (9618A) and two intermediate-to-fast-growing (5123C, 5123tc) Morris hepatomas and host livers. The mitochondrial proteins were solubilized and fractionated on sodium dodecyl sulfate:polyacrylamide slab gels. One Coomassie blue-stained band was absent or reduced in amount in all tumors relative to host livers.(More)
BACKGROUND Professional sport organizations in the United States have notable celebrity status, and several teams have used this "star power" to collaborate with local school districts toward the goal of affecting children's health. Program effectiveness is unknown due to the absence of comprehensive evaluations for these initiatives. The Memphis Grizzlies,(More)
Monosialogangliosides were extracted from the retinas and optic tecta of chick embryos at 6-12 days of incubation, and analyzed by high-performance liquid chromatography. The dominant monosialoganglioside was found to be N-acetylgalactosaminyl (N-acetylneuraminyl) galactosylglucosylceramide (GM2). The specific concentration of GM2 in both the retina and(More)
