Newly discovered <i>banjo-shuseki-bo</i> (square-shaped bone-pile burial) human bones from the Final Jomon Period Hobi shell-mound site, Aichi Prefecture, Japan

Genotype frequencies of the ABCC11 gene in 2000–3000-year-old human bones from the Epi-Jomon and Jomon sites in Hokkaido, Japan

In order to investigate further the allele frequencies of the adenosine triphosphate-binding cassette sub-family C11 (ABCC11) gene, which determines earwax phenotypes, among ancient populations in Hokkaido, Japan, the single-nucleotide polymorphism and the 27 bp deletion in the ABCC11 gene were analyzed in ancient DNA extracted from 38 Epi-Jomon, 24 Jomon, and one Satsumon specimens excavated f...

Growth and decline in complex hunter-gatherer societies: a case study from the Jomon period Sannai Maruyama site, Japan

The Sannai Maruyama site (3900-2300 BC) is one of the largest known from Japan’s Jomon period (14 000-300 BC). This study shows that over 1500 years the number of dwellings, their size, the type of stone tools and the fondness for figurines varied greatly. Nor was it a story of gradual increase in complexity: the settlement grew in intensity up to a peak associated with numerous grinding stones...

The estimation of cancer incidence in Aichi Prefecture, Japan: use of degree of completeness of registration.

This study was conducted to estimate true incidence of the total number of cancer cases and of cancers at selected sites in the population of Aichi Prefecture, Japan, using the degree of completeness of registration (CR). Information on incidence (I), death (D), and cases first notified via death certificate (DCN) was based on the data from 1976 to 1993. Using this information, CR for each canc...

Extraction and Analysis of Ancient DNA from Human Remains of Masjede Kabood Burial Site

Charcoal cigarette filters and lung cancer risk in Aichi Prefecture, Japan.

The lung cancer mortality rate has been lower in Japan than in the United States for several decades. We hypothesized that this difference is due to the Japanese preference for cigarettes with charcoal-containing filters, which efficiently absorb selected gas phase components of mainstream smoke including the carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone. We analyzed a subset of smo...
