SYNOPSIS. Death rates of A/J and CF1 female mice 4 weeks and 6 months of age were compared after the mice were infected with Plasmodium berghei NK65C deme (population) and NK65RR deme. Death rates were compared also when female A/J retired breeder mice were infected with blood passages 18 and 40 of NK65C.
NK65C was found to be less virulent than NK65RR. The 40th blood passage of NK65C was more virulent than the 18th passage, but still not as virulent at the NK65RR deme. A/J retired breeders were clearly more resistant to infection than 4 week old A/J mice, while little difference was found in the different age groups of the CF1 mice.
The shaft portion of the left femur from an individual occupationally exposed to Pu was used to investigate the suitability of an ethylenediamine extraction technique to separate mineral bone from organic material. Marrow in the lumen was removed before the extraction technique was used and was analyzed separately for Pu. Ethylenediamine extraction did not remove Pu from the mineral bone, even after treatment for 48 h. The total amount and the concentration of Pu was highest in mineral bone and lowest in the extracted organic material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
