Unicellular algae grow well under limiting CO2 conditions, aided by a carbon concentrating mechanism (CCM). In C. reinhardtii, this mechanism is inducible and is present only in cells grown under low CO2 conditions. We constructed a cDNA library from cells adapting to low CO2, and screened the library for cDNAs specific to low CO2-adapting cells. Six(More)
Nasopharyngeal carcinoma (NPC) has the highest metastatic potential among head and neck cancers. Distant metastasis is the major cause of treatment failure. The role of interleukin-8 (IL-8) in NPC progression remains unknown. Our multivariate survival analyses of 255 patients with NPC revealed that higher IL-8 expression in primary NPC tissue was an(More)
BACKGROUND The reported prevalence of unruptured cerebral aneurysms (UCAs) varies widely. OBJECTIVE To measure the prevalence of UCAs by using 3-dimensional time-of-flight magnetic resonance angiography in adults aged 35 to 75 years. DESIGN Cross-sectional study done between June 2007 and June 2011. SETTING Two communities chosen at random from 2(More)
In vitro and in vivo studies have demonstrated that lung cell apoptosis is associated with lung fibrosis; however the relationship between apoptosis of alveolar macrophages (AMs) and human silicosis has not been addressed. In the present study, AM apoptosis was determined in whole-lung lavage fluid from 48 male silicosis patients, 13 male observers, and 13(More)
Picroside II possesses a wide range of pharmacological effects and has been demonstrated to ameliorate cerebral ischemia and reperfusion (I/R) injury. However, its effects on renal I/R injury remain unclear. In the present study, the role of picroside II in attenuating oxidative stress and the inflammatory response in a rat model of renal I/R injury was(More)
BACKGROUND AND AIMS To explore the relationship between habitual tea consumption and arterial stiffness. METHODS This is a cross-sectional, epidemiological survey of 6589 male and female residents aged 40-75 in Wuyishan, Fujian Province, China. Tea consumption and other lifestyle characteristics were obtained by structured questionnaires. Pulse wave(More)
Dovitinib is a receptor tyrosine kinase (RTK) inhibitor targeting vascular endothelial growth factor receptors, fibroblast growth factor receptors and platelet-derived growth factor receptor β. Dovitinib is currently in clinical trials for the treatment of hepatocellular carcinoma (HCC). In this study, we used five HCC cell lines and five endothelial cell(More)
OBJECTIVE To compare the diagnostic accuracy of stroke volume variation (SVV) and pulse pressure variation (PPV) in studies that examined both parameters in the same patient population. METHODS Literature search was conducted in PubMed, EMBASE, CINAHL, and Google Scholar. Receiver operator characteristic (ROC) curves were examined, and summary ROC curves(More)
A highly efficient multicomponent reaction of 2-alkynylbenzaldehyde, sulfonohydrazide, alcohol, and α,β-unsaturated aldehyde or ketone is disclosed, which generates the diverse H-pyrazolo[5,1-a]isoquinolines in good yields. This reaction proceeds with good functional group tolerance under mild conditions with high efficiency and excellent selectivity.(More)
Increasing evidence suggests that transforming growth factor-beta 1 (TGF-β1) triggers epithelial to mesenchymal transition (EMT) and facilitates breast cancer stem cell differentiation. Gelsolin (GSN) is a ubiquitous actin filament-severing protein. However, the relationship between the expression level of GSN and the TGF-β signaling for EMT progression in(More)
