Recently, Aronson and colleagues (1) reported that men withprostate cancer receiving approximately 5 g/d of fishoil combined with a low-fat diet (15% kcal from fat) for 4 to 6 weeks before prostatectomy had 32% lower tumor ki67 staining compared with men consuming a Western diet (45%kcal from fat). This study is of interest because thedata suggest that dietary modification can greatly reduce tu...

INTRODUCTION Auxins are hormones that regulate plant growth and development. To accurately quantify the low levels of auxins present in plant and soil samples, sensitive detection methods are needed. In this study, the design and construction of two different whole cell auxin bioassays is illustrated. Both use the auxin responsive element HpaA as an input module but differ in output module. The...

In this study, we used two different types of bioassay, a contact filter paper toxicity bioassay and a soil toxicity bioassay, to compare the acute toxicity of twenty-four insecticides belonging to six chemical categories on earthworm species, Eisenia fetida. Results of the contact filter paper toxicity bioassay indicated that neonicotinoids were super toxic to E. fetida (48 h-LC(50) value rang...

The toxicity data of pesticides were summarized and compared amongst different animal species and types of bioassays. These comparisons showed the expected inter-species and inter-bioassay variability. After quantitative and statistical analysis of these data, it was concluded that, on the average, a 2-year dog bioassay detected toxic responses at similar doses as a 2-year rat study, and that b...

abstract background and aims: the cydia pomonella granulovirus (cpgv) is a baculovirus and very effective biological control agent against apple pest, codling moth, cydia pomonella l. especially for healthy organic apple production and protection.  not only, screening of cpgv isolates via biochemical variation, but also their biological variation is practically necessary.  however, the bioassay...
