Instability of glacial climate in a model of the ocean- atmosphere-cryosphere system.

Science (New York, N.Y.)

Schmittner A, Yoshimori M, Weaver AJ.
PMID: 11823604
Science. 2002 Feb 22;295(5559):1489-93. doi: 10.1126/science.1066174. Epub 2002 Jan 31.

In contrast to the relatively stable climate of the past 10,000 years, during glacial times the North Atlantic region experienced large-amplitude transitions between cold (stadial) and warm (interstadial) states. In this modeling study, we demonstrate that hydrological interactions between...

Differences in Cancer Risks in the South and North of Viet Nam.

Asian Pacific journal of cancer prevention : APJCP

Ngaon LT, Fukumitsu S, Kaneko S, Yoshimura T.
PMID: 12718630
Asian Pac J Cancer Prev. 2001;2(3):193-198.

Background: As there are few available data regarding cancers in Viet Nam, the aim of the present study was to evaluate cancer risk ratios and geographical differences in cancer incidences between the south and north populations in the 1990s....

Pattern and Time Trends of Stomach Cancer in Asia from 1950-99.

Asian Pacific journal of cancer prevention : APJCP

Ngoan LT, Yoshimura T.
PMID: 12718608
Asian Pac J Cancer Prev. 2002;3(1):47-54.

Background: As there is a lack of data on stomach cancer disease in Asia, the aim of the present study was to examine patterns and time trends for this neoplasm in Asian countries. Methods: A descriptive study was designed...

Morphological change of gold-dendrimer nanocomposites by laser irradiation.

Journal of colloid and interface science

Esumi K, Hayakawa K, Yoshimura T.
PMID: 14643252
J Colloid Interface Sci. 2003 Dec 15;268(2):501-6. doi: 10.1016/s0021-9797(03)00598-8.

Gold-dendrimer nanocomposites are prepared in aqueous solutions in the presence of poly(amidoamine)dendrimers (PAMAM) (generation 3 and 5) or poly(propyleneimine)dendrimers (PPI) (generation 3 and 4) by wet chemical NaBH(4) method. Thus prepared gold-dendrimer nanocomposites are irradiated by laser at 532...

Large-scale preparation of high-molecular weight DNA from buccal mucosa.

Legal medicine (Tokyo, Japan)
