| effect of various histological fixatives on fluorescent antibody detection of legionnaires disease bacteria. | human lung tissue containing the legionnaires disease bacterium was fixed in seven different histological fixatives, processed, and embedded in paraffin. deparaffined sections from each were stained by fluorescent antibody and by dieterle silver impregnation. with the fluorescent antibody stain, the legionnaires disease bacterium could be detected in tissues prepared with any of the fixatures, but the dieterle silver impregnation was not satisfactory on zenker-fixed tissues. | 1979 | 91621 |
| visualization of subsurface structures in cells and tissues by backscattered electron imaging. | a fraction of the beam electrons which interact with a specimen scatter back. the number of backscattered electrons (be's) increases with the atomic number of the elements encountered. cell and tissue structures lacking a heavy metal content yield few be's compared to structures affixed with heavy metals, either vitally or by means of staining methods applied after fixation. the be imaging mode of a scanning electron microscope (sem) provides an intensity map of the be yield from the specimen. b ... | 1979 | 93305 |
| priming increases the amount of interferon mrna in poly(ri).poly(rc)-treated l cells. | priming by mouse interferon pre-treatment resulted in an accumulation of interferon mrna in poly(ri).poly(rc)-treated l cells, starting early in the period of interferon synthesis. on electrophoresis, the priming activity of an interferon preparation co-migrated with the antiviral activity, which suggests identity of the functional principle(s) for these activities. | 1979 | 94345 |
| recognition of individual procaryotic and eucaryotic transfer-ribonucleic acids by b subtilis adenine-1-methyltransferase specific for the dihydrouridine loop. | bulk trna from yeast and rat liver can be methylated in vitro with -adenosylmethionine and b, subtilis extracts. the sole product formed is 1-methyladenosine (m1a). this trna (adenine-1) methyltransferase converts quantitatively the 3'-terminal adenosine-residue in the dihydrouridine-loop of trnathr and trnatyr from yeast into m1a. out of 16 eucaryotic trnas with known sequences 6 accepted methyl groups, all at a molar ratio of 1. these trnas have in common an unpaired adenosine-residue at the s ... | 1978 | 99729 |
| comparison of antigens of pneumonia-associated mycoplasma species by gel diffusion. | comparison of fluorocarbon-extracted antigens of six mycoplasma species by double immunodiffusion and counterimmunodiffusion techniques revealed a close reciprocal relationship among mycoplasma dispar, m. ovipneumoniae, and m. hyopneumoniae. a lesser degree of cross-reaction was also demonstrated between these three species and m. hyorhinis and m. bovoculi. the interrelationships were more clearly demonstrated by double immunodiffusion than by counterimmunodiffusion. | 1978 | 101469 |
| hydrolysis of erythrocyte membrane phospholipids by a preparation of phospholipase c from clostridium welchii. deactivation of (ca-2+, mg-2+)-atpase and its reactivation by added lipids. | 1. haemoglobin-free erythrocyte ghosts were prepared in 40 imosm bicarbonate buffer, ph 7.4, containing 1 mm edta (40 imosm/l mm edta). the ghost preparation was highly permeable on preparation but partially resealed on incubation in media containing ca-2+. 2. a partially purified preparation of phospholipase c from clostridum welchii caused an increase in observed mg-2+-atpase activity, reflecting a change in the permeability of the ghost to substrate. the phospholipase did not decrease mg-2+-a ... | 1975 | 123773 |

| high tyrosine-specific protein kinase activity in normal human peripheral blood lymphocytes. | tyrosine-specific protein kinase (atp:protein phosphotransferase, ec 2.7.1.37) activity was measured in normal human nonadherent peripheral blood lymphocytes using synthetic peptide substrates having sequence homologies with either pp60src or c-myc. a high level of tyrosine-specific protein kinase activity was found associated with the cell particulate fraction (100 000 x g pellet). high-pressure liquid chromatography and phosphoamino acid analysis of the synthetic peptide substrates substantiat ... | 1985 | 4038888 |
