To determine the contributions of calcium to development of ultrastructural damage and neuronal death after mechanical injury, we amputated primary dendrites from over 300 cultured mammalian spinal neurons under normal (1.8 mM) or low (less than or e

The spoIIIE gene of Sporosarcina ureae encodes a 780-residue protein, showing 58% identity to the SpoIIIE protein of Bacillus subtilis, which is thought to be a DNA translocase. Expression of the S. ureae spoIIIE gene is able to restore sporulation i

The paper compares Daphnia and cell culture bioassays of the toxicity of a reference compound, m-cresol, and then applies those procedures to complex fractions derived from oil-refinery effluents. The cell culture assay is established as a sensitive,

A new ultrastructural technique has been developed to study the geometry of cell wall assembly in Streptococcus faecalis, which is believed to occur between pairs of raised bands located on the organism's surface. Three-dimensional reconstructions of

Summary: Resume: Zusammenfassung The loss of acrolein by volatilization and degradation from a large tank of water is described. The standard analytical method for carbonyl compounds, a colorimetric reaction with dinitrophenylhydrazine did not distin

Experimental data for the decay of acrolein approximated first order kinetics. The reaction continued to completion in local waters but in buffered solution (pH 5.1-8.6) an equilibrium was reached after reaction of about 92% of the acrolein. It is pr

Cell buoyant densities were determined by centrifugation in Percoll gradients containing exponential-phase cells of Streptococcus faecium ATCC 9790 grown at a mass doubling time of about 33 min. This bacterium showed the highest average density value

A new ultrastructural method was used to study rounds of envelope synthesis that occur in Streptococcus faecalis in "growth zones" found between pairs of naturally occurring surface markers. The technique consists of producing three-dimensional recon

Exponential-phase cells of Streptococcus faecalis ATCC 9790 were treated with a concentration of cerulenin (5 micrograms/ml) that has been shown to block both lipoteichoic acid and lipid synthesis and cell division within 10 min. The morphological ef
