In April 2012, perioperative oral management (POM) was approved for inclusion in the national health insurance system of Japan to prevent the occurrence of pneumonia, a major complication in cancer patients. The subsequent decrease in the incidence o

We investigated the microhabitats of benthic foraminifera and stable oxygen and carbon isotope compositions of living (stained) Elphidium batialis Saidova off Hidaka (northern Japan) in the Northwestern Pacific continental margin. In the study area,

Foraminiferal assemblage distribution was used to reconstruct the palaeoenvironmental conditions that prevailed during the deposition of the core MD179-3312 in the eastern margin of the Japan Sea. One hundred six benthic foraminifera species belongin

We reconstructed the paleoenvironmental history of surface and deep water over the last 130 kyr from oxygen and carbon isotope ratios of planktonic and benthic foraminifera in two cores (MD179-3312 and MD179-3304) from the Joetsu Basin, eastern margi

We investigated the life history of Ammonia “beccarii” (Linne) forma 1 in Lake Saroma, Hokkaido, northern Japan, to understand the variation in its response to a cool, brackish environment. This study was based on observations of seasonal change

Analyses of the benthic and planktonic foraminiferal record were conducted to understand temporal variations in sea-floor oxygenation and surface productivity during periods of dark-layer deposition between 160 and 15 ka, based on data from sediment

Stable carbon and oxygen isotopic compositions (δ13C and δ18O) of benthic foraminiferal carbonate shells have been used to reconstruct past bottom-water environments. However, the details of factors controlling the isotopic disequilibrium between t
