When NCTC clone 929 (strain L) cells were grown either continuously or at intervals in toxic human serum, they became resistant to the toxic substance or substances. The resistance developed to toxic human serum was passed from one cell generation to another; i.e., it was heritable. The resistance to toxic human serum, developed in strain L cells, was associated with a decrease in their ability...

Toxic epidermal necrolysis-like lesions have been described in the setting of lupus erythematosus, and have been considered as a specific hyperacute variant of cutaneous lupus erythematosus, with features different from classical drug-related toxic epidermal necrolysis. We report here a series of three patients with lupus erythematosus who presented with severe worsening of their cutaneous dise...

The genes encoding the ribosomal P-proteins CcP0, CcP1 and CcP2 of Ceratitis capitata were expressed in the conditional P0-null strains W303dGP0 and D67dGP0 of Saccharomyces cerevisiae, the ribosomes of which contain either standard amounts or are totally deprived of the P1/P2 proteins, respectively. The presence of the CcP0 protein restored cell viability but reduced the growth rate. In the W3...

The possibility of separating ascites tumor cells with different numbers of chromo somes by means of counter-streaming centrifugation has been studied with the hy perdiploid Ehnlich ascites tumor (ELD) and its hypertetraploid offshoot (ELT). From ELD a fraction significantly higher in deoxyribonucleic acid phosphorus (DNAP) per cell than the unfractionated suspension was obtained. Inoculated in...

An issue that covers the tiny — the chromo­ somes of m alaria -carry ing mosquitoes — to the massive — the two bil­ lion peop le th o u g h t to be §ee Also affected with the tuberculo­ sis virus — will take center stage for seven panelists in th e N o tre D am e F o ru m today.

the aim of this trial was to determine the toxic effect of oms-43 on spraymen and inhabitants. the spraying operation lasted for 30 successive days, and two teams consisting of 20 spraymen, 2 mixers, 4 foremen and team leaders were engaged in this operation. the operators were under systematic and closed clinical observation and cholinesterase determination (tintometric method) during the opera...
