To better understand the photosynthesis under stress, the effect of cadmium on carbon assimilation and chloroplast ultrastructure of a newly found Zn/Cd hyperaccumulator Picris divaricata in China was investigated in solution culture. The shoot and root Cd concentrations increased with increase in Cd supply, reaching maxima of 1109 and 5604mgkg(-1) dry(More)
OBJECTIVES Esophageal cancer is an extremely aggressive gastrointestinal malignancy, which appears to result from a complex interplay between genetic and environmental agents. The genetic loci conferring susceptibility have yet to be fully defined. Considering the role of programmed death-1 (PD-1) in immune regulation and tumor pathogenesis, we genotyped(More)
The mechanisms of stabilization by silicon-rich amendments of cadmium, zinc, copper and lead in a multi-metal contaminated acidic soil and the mitigation of metal accumulation in rice were investigated in this study. The results from a pot experiment indicated that the application of fly ash (20 and 40gkg(-1)) and steel slag (3 and 6gkg(-1)) increased soil(More)
The association between the Serine/threonine kinase 15 (STK15) F31I polymorphism (rs2273535) and cancer susceptibility remains controversial. To further investigate this potential relationship, we conducted a comprehensive meta-analysis of 27 published studies involving a total of 19,267 multiple cancer cases and 24,359 controls. Our results indicate(More)
BACKGROUND The association between Aurora-A V57I (rs1047972, G>A) polymorphism and cancer susceptibility has been widely studied. However, the results are inconsistent. METHODOLOGY/PRINCIPAL FINDINGS To obtain a more precise evaluation of the relationship, we performed a meta-analysis of 14 case-control studies involving a total of 11,245 cancer cases and(More)
The effect of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] on two leukemia cell lines, K562 and SHI-1, and its relation to the expression of different subtypes of polypeptide: N-acetylgalactosaminyltransferase (pp-GalNAc-T) was studied. With morphological and cell flow-cytometric method, it was found that 1,25(OH)2D3 induced the differentiation of both leukemia(More)
Most of the antiangiogenic strategies used in oncology principally target endothelial cells through the vascular endothelial growth factor (VEGF) pathway. Multiple kinase inhibitors can secondarily reduce mural cell stabilization of the vessels by blocking platelet-derived growth factor receptor (PDGFR) activity. However, sphingosine-1-phosphate (S1P),(More)
The objective of this study is to conduct a bibliometric analysis of all biological invasions-related publications in the Science Citation Index (SCI) from 1991 to 2007. The indicator citation per publication (CPP) was used to evaluate the impact of articles, journals, and institutions. In the 3323 articles published in 521 journals, 7261 authors from 1905(More)
Molybdenum disulphide is a novel two-dimensional semiconductor with potential applications in electronic and optoelectronic devices. However, the nature of charge transport in back-gated devices still remains elusive as they show much lower mobility than theoretical calculations and native n-type doping. Here we report a study of transport in few-layer(More)
The purposes of this study were to evaluate the treatment outcome of patients with small cell lung cancer (SCLC), focusing on the prognostic factors for response to therapy and overall survival. A retrospective analysis was performed on 116 consecutive patients with SCLC diagnosed from January 1997 to December 2005. Collected data included demographic(More)
