A reduced physiological F-fluorodeoxyglucose uptake in the brain and liver caused by malignant lymphoma being deprived of the tracer.

Purpose : To investigate whether or not the physiological brain and liver FDG uptake are decreased in patients with highly accelerated glycolysis lesions. Methods : We retrospectively analyzed 51 patients with malignant lymphoma. We compared the FDG uptake in the brain and liver of the patients with that in a control group.

Molecular epidemiological analyses of Japanese encephalitis virus isolates from swine in Japan from 2002 to 2004.

To characterize Japanese encephalitis virus (JEV) strains recently prevalent in Japan, JEV surveillance was performed in pigs from 2002 to 2004. Eleven new JEV isolates were obtained and compared with previous isolates from Japan and other Asian countries. All of the isolates were classified into genotype 1 by nucleotide sequence analysis of the E gene.
