534841“…These original findings are now in question as it has been reported that the p-values associated with the tests of differential expression for null probesets (i.e., probesets designed to be fold change 1 across the two arms of the experiment) are not uniformly distributed. Two recent publications have speculated as to the reasons the null distributions are non-uniform. …”

534842“…This investigation illustrated how sequences derived from surface protein genes and computer simulations can be used to investigate variation generation mechanisms. Such in silico experiments of self-replicating sequences undergoing random mutations and genomic re-arrangements can offer insights into the diversity generation potential of the genes under study. …”

Mutagenesis experiments demonstrated that hydroquinones cause sequence-specific frameshift mutations involving deletion of a single cytosine from the DNA sequence 5'-172-CCCCC176-3' or a single guanosine from the complementary strand sequence 5'-GGGGG-3' in the supF tRNA gene. …”

H., Schächtele, C., Klemm, K., Grunicke, H.“…Remarkably, [3H]vinblastine-sulphate binding competition experiments using P-gp-containing crude membrane preparations demonstrated similar dose dependencies as found for MDR reversion by the three modulators, i.e. decreasing efficacy in the series dexniguldipine-HCl > dexverapamil-HCl > GF 109203X. …”

534849por Wood, W. Barry“…The relation of the observed phenomena to the curative action of anti-pneumococcal serum has been briefly discussed, and it is pointed out that the principal effect of antiserum is to cause immobilization of the pneumococci in the advancing edema zone. Experiments to be reported in a later publication have shown that sulfapyridine exerts a similar effect through a different mechanism.…”

The aim of the experiments reported here was to attempt to induce tolerance in each of the two cell populations to determine which cell type dictates the specificity of the response. …”
