Carcinoid syndrome is a rare disorder caused when elevated levels of vasoactive substances secreted by a carcinoid tumor fail to be metabolized by the liver. This can occur for a variety of reasons including metastatic invasion of the organ. Carcinoid syndrome results in elevated levels of 5-hydroxyindoleacetic acid in the urine. Clinical manifestations include: flushing, diarrhea, bronchospasm...
Age Determination 105038 Kawano, Y. & Yuhara, M. Chronological and isotope geological study of Cretaceous granitic rocks, upper reach of the Nakagawa river, Fukuoka Prefecture. J. Geol. Soc. Japan, 114, 218-230, 8 figs., 2 tables (in Japanese with English abstract), 2008. Cretaceous granitic rocks, consisting of Itoshima granodiorite and Sawara granite, are occurred at upper reach of the Nakaga...
Introduction Reconstruction of past climate change can provide us valuable information about the time, scale, and details of climate changes. For reconstruction of late quaternary cl...
The D’Entrecasteaux Islands of south-eastern Papua New Guinea are active metamorphic core complexes that formed within a region where the plate tectonic regime has transitioned from subduction to rifting. While rapid, post 4 Myr exhumation and cooling of amphibolite and greenschist facies rocks that constitute the footwall of the crustal scale detachment fault system have been previously docume...
A new dataset for the high-pressure to ultrahigh-pressure Western Gneiss Region allows the definition of distinct structural and petrological domains.Much of the study area is an E-dippinghomoclinewith E-plunging lineations that exposes progressively deeper, more strongly deformed, more eclogite-rich structural levels westward. Although eclogites crop out across the WGR, Scandian deformation is...
The complex interplay between depositional facies and diagenesis in dolostones presents numerous challenges for calculating petrophysical properties from wireline logs. Complex pore geometries and mineralogies control rock petrophysical properties, and equations for calculating porosities and saturations must therefore be tailored to specific pore geometry-mineralogy combinations. The complex m...
The hydraulic conductivity of aquifers is a key parameter controlling the interactions between resource exploitation activities, such as unconventional gas production and natural groundwater systems. Furthermore, this parameter is often poorly constrained by typical data used for regional groundwater modeling and calibration studies performed as part of impact assessments. In this study, a syst...
Ferrimagnetic greigite (Fe3S4) is widespread in the sedimentary environment. Despite abundant reports of occurrence marine and lacustrine deposits, its formation mechanisms deltaic deposits remain poorly studied. Here we investigate Holocene Yangtze River delta using granulometric, magnetic geochemical methods. The studied cores consist tidal river, estuary, shallow facies ascending order. grei...
We show that inferences of competence based solely on facial appearance predicted the outcomes of U.S. congressional elections better than chance (e.g., 68.8% of the Senate races in 2004) and also were linearly related to the margin of victory. These inferences were specific to competence and occurred within a 1-second exposure to the faces of the candidates. The findings suggest that rapid, un...
