The worldwide opening of a massive amount of unlicensed spectra around 60 GHz has triggered great interest in developing affordable 60-GHz radios. This interest has been catalyzed by recent advance of 60-GHz front-end technologies. This paper briefly reports recent work in the 60-GHz radio. Aspects addressed in this paper include global regulatory and(More)
Zoonosis has been suggested for hepatitis E virus (HEV) infection, but so far is based only on indirect evidence. We experienced a series of cases of HEV infection among people who had eaten uncooked deer meat 6-7 weeks before. On testing, a left over portion of the deer meat, kept frozen to eat in the future, was positive for HEV RNA, whose nucleotide(More)
Dopamine (DA)-producing neurons in the ventral midbrain are generated from a specified neuronal lineage and form selective axonal pathways that mediate multiple CNS functions. Expression of the gene encoding tyrosine hydroxylase (TH), which is a key enzyme of catecholamine biosynthesis, is regulated during the development of midbrain DA neurons. In the(More)
In Japan, indigenous acute hepatitis E is not a rare disease, and is mainly caused by hepatitis E virus (HEV) genotypes 3 and 4. Whether there is a difference in clinical features between the two genotypes remains unclear. This study compares the clinical features of patients infected with the two. From January, 1994, to December, 2003, 9 infected with HEV(More)
Zoonosis has been implicated in hepatitis E virus (HEV) transmission. We examined wild boar living in a forest of Hyogo prefecture, Japan, and found HEV RNA in three of seven boars. A full-genome HEV isolate from one of them was revealed to be 99.7% identical to a previous isolate from a wild deer hunted in the same forest and to those from four patients(More)
Hepatitis E virus (HEV), a single-strand RNA virus, has been recovered not only from human beings but also from various species of animals. Here we report our results suggesting that mongoose should be added to the list of reservoir animals of HEV. Of 100 mongooses we examined in Okinawa, Japan, 21 were thought to be positive for anti-HEV antibodies, among(More)
BACKGROUND In industrialized countries, sporadic cases of hepatitis E have been reported in individuals who have never been in an endemic area. Hepatitis E virus (HEV) infection commonly occurs via the fecal-oral route but a potential risk of transfusion transmission route has been suggested. STUDY DESIGN AND METHODS A 67-year-old Japanese male patient(More)
BACKGROUND Five cases of transfusion transmission of hepatitis E virus (HEV) have been reported so far. The infection routes of the causative donors remain unclear, however. Also, the progress of virus markers in the entire course of HEV infection has not been well documented. STUDY DESIGN AND METHODS Nucleic acid testing was performed by real-time(More)
OBJECTIVE Ranges of variation and conservation in sequence need to be defined for detecting and genotyping hepatitis E virus (HEV). METHODS Six HEV isolates from Japanese patients were sequenced over the entire genome and compared phylogenetically along with 16 reported HEV isolates, including two from pigs. RESULTS Three of the six HEV isolates were of(More)
