A bioassay of 2,5-dithiobiurea for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 2,5-Dithiobiurea was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species, with the exception of high dose male rats, of which there were only 49. The dietary concentrations used in the chronic bioassay were 0.6 percen...

To be effective, educational efforts for physicians must consider providers' knowledge and beliefs about what causes disparities and what can be done about them. METHODS AND RESULTS We conducted a Web-based survey of 344 cardiologists to determine ...
The erythropoietic effects of sustained intraperitoneal (i.p.) administration of CoCl2 and NiCl2 were compared with the effects of a single intrarenal (i.r.) injection of alpha Ni3S2 in female Fischer-344 rats. Infusion of NiCl2 by osmotic minipumps (0.85 mg Ni per day, i.p., for 24 days; total dose = 20 mg Ni per rat) did not alter the blood hematocrit or reticulocyte count during six weeks of...

BACKGROUND Patients who have had major trauma are at very high risk for venous thromboembolism if they do not receive thromboprophylaxis.

METHODS Consecutive adult patients admitted to a trauma center who had Injury Severity Scores of at le...
The isoflavone ME-344 is a potent anti-cancer agent with preclinical and clinical efficacy in solid tumors. Yet, the mechanism of action of ME-344 has not been fully defined and the preclinical efficacy in leukemia has not been established. Therefore, we investigated the anti-leukemic properties and mechanism of action of ME-344. In a panel of 7 leukemia cell lines, ME-344 was cytotoxic with an...
