alterations in the expression of the cytomegalovirus-induced cytopathogenic effect in fibroblasts by aflatoxin b1.aflatoxin b1 has been shown both to promote and to alter the expression of the cytopathogenic effect observed when human fibroblasts are challenged with human cytomegalovirus (cmv). although the cells become round, as is the characteristic effect of this virus on fibroblasts, multinucleate cells are seen to arise from cell fusion within 48 h after virus addition.1978218602
a comparison of the biological and biochemical properties of 1-(4-amino-2-methylpyrimidin-5-yl)methyl-3-(2-chloroethyl)-3-nitrosourea and 2-[3-(2-chloroethyl)-3-nitrosoureido]-d-glucopyranose.1-4-amino-2-methylpyrimidin-5-yl)methyl-3-(2-chloroethyl)-3-nitrosourea (acnu) is a water-soluble nitrosourea that has produced delayed hematological toxicity in man during phase 1 clinical trials. acnu has in vitro alkylating activy 40% less than that of 2-[3-(2-chloroethyl)-3-nitrosoureido]-d-glucopyranose (chlorozotocin) but shares the property of negligible carbamoylating activity with the latter compounds. acnu is highly active against murine l1210 leukemia. however, the maximum therapeutic ...1978145314
yersinia enterocolitica and pseudotuberculosis infection in children.the clinical symptoms of infections with y. ent. and pseudotub. are of a different nature. whether the infection becomes apparent in form of a pseudo-appendicitis, enterocolitis or a typho-septic disease does apparently not only depend on the type of pathogens but also on the children's condition with regard to their resistance. all forms mentioned are observed in case of infections with yersinia pseudotuberculosis as well as in case of infections with yersinia pseudotuberculosis as well as in c ...1978343179
influence of fibrinogen degradation products (fdp) on the atpase activity in the rat heart.influence of fibrinogen degradation products (fdp) on the atpase activity in the rat heart. acta physiol. pol., 1978, 29 (2): 185--187. the influence of dialysable fibrinogen degradation products (fdp) on the atpase activity was studied. it was found that fdp augment the mg(2+)-- dependent atpase and slightly decrease the (na+--k+) dependent atpase in the rat heart. it is concluded that biological activity of examined peptides depend on other mechanisms than the direct effect on atpase in the he ...1978148831
formylation of initiator trna methionine in procaryotic protein synthesis: in vivo polarity in lactose operon expression.eucaryotic and procaryotic organisms differ in two aspects of their translation machinery: polycistronic messengers are expressed as a sequence of individual proteins only in procaryotes, and the initiation of protein synthesis proceeds with an initiator trna which is found to be modified (formylated) in procaryotes and not in eucaryotes. in the present study, we show that formylation is required in vivo for the coordinate expression of the escherichia coli lactose operon. our experiments are co ...197898518
