英文: Background: Animal studies suggest that hydrazine is a lung carcinogen, but human studies have been rare, rather small, and limited to cancer mortality.
英文: Conclusions: The findings reported here are consistent with our previous results for lung cancer mortality; our new results suggest that exposure to hydrazine increases the risk of incident lung cancers.
英文: In particular, the resulting active ester with pentafluorophenol facilitated the subsequent reaction with an amine and the hydrazine derivative to yield the C-terminal amide and hydrazide, respectively.
英文: Nanosize silver particles have been prepared by reduction of aqueous solution of AgNO3 in the presence of polyvinylpyrrolidone, ethanol and de-ionized water, hydrazine hydrate was used for the reduction.
英文: Results: Exposureto hydrazine was positively associated with lung cancer incidence (estimated rate ratio for high vs low exposurewith 20-year lag = 2.5; 95% confidence interval = 1.3-4.9) and with colorectal cancer incidence (2.2; 1.0-4.6).
