Cholecystokinin (CCK) is a growth factor for normal pancreas. Nu merous studies also suggest that CCK promotes pancreatic carcinogenesis in the rat. Our previous studies suggested that growth of preneoplastic pancreatic foci was stimulated by CCK more than that of normal pan creas. We hypothesized that such differential growth might be due to increased numbers of CCK receptors in neoplastic tis...

Recently, evidence was reported for the belief that a carcinogenic agent, †̃20-methyleholanthrene, could be secreted into the milk of a lactating ani mal and thereby gain entrance into the bodies of the offspring to cause an abnormally high mci dence of neoplasms (1). Further positive evidence for this mode of excretion of methyleholanthrene has now been obtained by means of ultraviolet ab sor...

A number of reports have described the occurrence of liver cell adenomas in women using oral contraceptives. Circum stantial evidence derived from human and early experimental animal data, together with the recent report of Taper [Cancer (Phila.), 42: 462-467, 1978], suggests that oral contraceptive steroids may be liver tumor promoters. The objective of this study was to determine whether the ...

 The foreign exchange market (FX market) accounts for 40% of the total volume of the world’s e-commerce by its own. Based on statistics, sometimes up to 90 per cent of the traders lose their total capital in this market just within six months to one year and leave this market. The probability of loss in the FX market can be estimated by probability theory. The present paper intends to demonst...

To elucidate the significance of tRNA modification for human lymphoid maturation and malignant transformation, the amount of tRNAs having guanosine in place of queuosine, i.e., (Q-)tRNA, was determined in several human lymphomas and leukemias by exchanging the respective unmodified guanosine residue for [3H]guanine, a reaction catalyzed by a specific tRNA transglycosylase from Escherichia coli....
