| the flow properties of axoplasm in a defined chemical environment: influence of anions and calcium. | the flow properties of axoplasm have been studied in a defined chemical environment. axoplasm extruded from squid giant axons was introduced into porous cellulose acetate tubes of diameter roughly equal to that of the original axon. passage of axoplasm along the tube rapidly coated the tube walls with a layer of protein. by measuring the rate of low back and forth along the tube, the rheological properties of the axoplasm plug were investigated at a range of pressures and in a variety of media. ... | 2000 | 92032 |
| ia determinants on human t-cell subsets defined by monoclonal antibody. activation stimuli required for expression. | the nature of ia antigens which appear on human t cells after activation and the stimuli required for their expression was examined utilizing a monoclonal antibody reactive with the ia antigen framework. t cells were purified using monoclonal antibodies directed either at the entire t-cell population (okt3) or the t-cell inducer subset (okt4). by indirect immunofluorescence, it was shown that the human t-cell population contains no detectable ia+ cells in the resting state. in contrast, in exces ... | 1979 | 92523 |
| [physicochemical properties of neurospecific basic protein (scp) of the spinal cord]. | basic protein (scp) known as antiencephalytogenic was isolated from the bull spinal cord and spinal roots. the protein is purified to a molecular homogeneous state, some of its physicochemical properties are studied. molecular homogeneity of the protein is established by the method of disk electrophoresis in 15% polyacrylamide gel with sodium dodecyl sulphate present and by analytic ultracentrifugation. during electrophoresis in 15% polyacrylamide gel at ph 4.0 the protein movement occurs only i ... | 1979 | 92837 |
| penicillin and cephalosporin immunogenicity in man. | whether cross-allergenicity exists between the penicillin and cephalosporin antibiotics is controversial. a solid-phase radioimmunoassay was adapted to detect drug-specific igg, igm and ige antibodies. penicillin and cephalothin-specific serum immunoglobulins were determined in patients' serum before and after a therapeutic course of sodium cephalothin. changes in igg, igm and ige antipenicillin and anticephalothin antibodies, respectively, occurred and were closely correlated to one another (r ... | 1979 | 92902 |
| quantitative succinate-dehydrogenase histochemistry. iii. variations in histochemical succinatedehydrogenase activity in different cross-sections of the same muscle fibre. | the variation in histochemical sdh-activity at different levels in the same muscle fibre was determined in muscle fibre cross-sections both by visual classification and quantitative determination of the formazan-deposits. this work resulted in a confirmation of the earlier micro-biochemical studies of spamer and pette (1977, 1979) and lowrey et al. (1978) that the activity of enzymes of the citric acid cycle is not homogeneously distributed in a muscle fibre over its entire length. in addition i ... | 2001 | 93101 |
