| the pattern of sporulation in anabaena circinalis and comments on the role of heterocysts in sporulation in blue-green algae. | cells between two intercalary heterocysts differentiate at random into spores in a. circinalis. one or more cells, which fail to transform into spores, are present between the two adjacent spores, and these cells disorganize later. a critical c:n ratio regulates sporulation and heterocyst formation. during sporulation the reductive ability of the heterocyst gradually diminishes. it is concluded on the basis of this and other evidence that sporulation is regulated by interactions between heterocy ... | 1978 | 97869 |
| uptake of [14c]-aflatoxin b1 by liver and kidney slices of different animal species. | uptake of aflatoxin [14c]-b1 by the liver and kidney slices of different animal species clearly indicates that the transport of the toxin to different organs of the respective species is not the major cause for the reported variation in the species susceptibility to aflatoxin. | 1978 | 97879 |
| [an index of blood neutrophil injury in man and animals immunized with live anthrax vaccine]. | the authors present the results of study of the blood neutrophil injury in guinea pigs, rabbits, monkeys, and also humans inoculated subcutaneously with live anthrax vaccine. along with intradermal test with anthraxin, the mentioned test is suggested to assess the immunological status of persons immunized with anthrax vaccine. | 1978 | 97884 |
| [prospects for the use of blood substitutes made in the ussr with the expired date of validity]. | as revealed, blood substitutes--aminopeptide, caseine hydrolysate, and hydrolysine with the expired date of validity could be used as the basis of nutrient media for the cultivation of bacteria. bacterial growth proved to be the optimum in addition to the blood substitutes of a 0.25--0.5% of yeast extract. | 1978 | 97885 |
| the biology of ethics or the ethics of biology? the biologist's quest for meaning. | the biologist's involvement in value issues concerning the metholology of biological sciences, in establishing the biological basis of ethics and in creating a value system based on biological knowledge is examined. it is proposed that the roots of this involvement are in the conflict of the knowledge-ethic with the established system of values and in the need for metaphysical explanation. | 2001 | 97886 |

| biochemistry and immunochemistry of membrane-bound enzymes. | membrane-bound enzymes have certain specific differences compared with soluble enzymes. membrane-binding often enables greater catalytic activity of associated enzymatic reactions, their regulation by low molecular weight substances (substrates and allosteric effectors, hormones) and compartmentation, etc. on the other hand, the binding of enzymes to membranes causes considerable difficulties as regards their isolation and the determination of their homogeneity and substrate specificity. membran ... | 1977 | 97930 |
