Pyrimidine nucleotide metabolism in Rhizobium meliloti: purification of aspartate transcarbamoylase from a pyrimidine auxotroph (open access)

Pyrimidine nucleotide metabolism in Rhizobium meliloti: purification of aspartate transcarbamoylase from a pyrimidine auxotroph

Rhizobium aspartate transcarbamoylase (ATCase; EC 2.1.3.2) was previously believed to be similar to the Pseudomonas ATCase which has been studied extensively. To facilitate the study of the Rhizobium ATCase a pyrimidine-requiring mutant of R. meliloti was isolated and used in the purification of the enzyme.

Raman studies of reorientational dynamics in liquids (open access)

Raman studies of reorientational dynamics in liquids

Raman and/or infrared (IR) bandshape analysis to probe molecular dynamics in liquids has become a rapidly expanding field of study in recent years. Determination of spinning and tumbling diffusion constants, Dι and D⊥, which characterize the reorientation of symmetric-top moleclues has been successfully studied in a number of D6H and D3H molecules. For molecules of CV3 symmetry, however, previous attempts to extract spinning diffusion constants from Raman doubly degenerate vibrations (E mode) have proved unsuccessful. Presented here is a new methodology which resolves the problems encountered by former researchers through calculation of Dι utilizing the narrower Lorentzian component of E vibrations.

Synthesis and reactions of poly(ethynyldialkylsilanes) (open access)

Synthesis and reactions of poly(ethynyldialkylsilanes)

A nucleophilic cleavage reaction of 2,2,5,5,8,8-hexamethyl-2,5,8-trisilanona-3,6-diyne, I, with several bases, occurs rapidly at room temperature in both polar and non-polar solvents. An attack occurs exclusively at the central silicon regardless of the steric requirements of the bases (alkyllithium). The major products from the reaction of I with tert-butyllithium followed by hydrolysis were 2,2,5,5,6,6-hexamethyl-2,5-disilahepta-3-yne, II, and 2,2,5,5-tetramethyl-2,5-disilahexa-3-yne, VI.

Brain-Reactive Antibodies: Molecular Specificity and Relationship to Biological Aging (open access)

Brain-Reactive Antibodies: Molecular Specificity and Relationship to Biological Aging

Brain-reactive antibodies (BRA) increase in frequency with age in several mammalian species and may be involved in the pathogenesis of age-related dementia. In this experiment, the molecular specificity of BRA in mouse sera was determined using an immunoblot assay, and the relationship of BRA to longevity was studied by comparing the rate of formation of specific BRAs in diet restricted C57BL/6NNia, B6D2F1/NNia, and DBA/2NNia, genotypes which differ markedly in life-span.

Evaluation of the Efficacy of the Stress Protein Response as a Biochemical Water Quality Biomonitoring Method (open access)

Evaluation of the Efficacy of the Stress Protein Response as a Biochemical Water Quality Biomonitoring Method

The stress protein response (SPR) is a conserved and ubiquitous mechanism that enables cells to tolerate a wide variety of environmental insults. This response involves the preferential synthesis of an array of proteins with different molecular weights. These proteins perform a variety of functions, such as protein folding, multimeric protein assembly, steroid receptor binding, and heme catabolism. To evaluate the potential use of the SPR as a biomonitoring tool, a stepwise plan was utilized that proceeded through various physical and chemical laboratory exposures and culminated with a field validation study. The goals of the laboratory exposures were threefold: (1) determine the time required for induction of the SPR; (2) determine the dose-responsiveness of the SPR; and (3) compare the increased syntheses and accumulations of stress proteins to classical toxicological endpoints (i.e. percent mortality, LC50, LC1, etc).

The principle of "sankofa" in elementary music instruction in southern Ghana: selected school personnel's views of and their role in its implementation

The study ascertained elementary school teachers' and supervisors' views about their role in the implementation of Sankofa (Go back and retrieve) in school music. Sankofa mandates the integration of distinctive Ghanian traditional values and practices with Western educational concepts in the school curriculum. In music, it calls for the fusion of multi-ethnic musics of Ghana with Western musical concepts in public school music instruction. Some concerns expressed by Ghanian music educators regarding teachers' negative attitudes toward Sankofa in public school music had prompted the study.
