The rapid development of nanotechnology will inevitably release nanoparticles (NPs) into the environment with unidentified consequences. In addition, the potential toxicity of CeO(2) NPs to plants and the possible transfer into the food chain are still unknown. Corn plants (Zea mays) were germinated and grown in soil treated with CeO(2) NPs at 400 or 800(More)
[1] Agricultural lime can be a source or a sink for CO2, depending on whether reaction occurs with strong acids or carbonic acid. Here we examine the impact of liming on global warming potential by comparing the sum of Ca and Mg to carbonate alkalinity in soil solutions beneath unmanaged vegetation versus limed row crops, and of streams and rivers in(More)
It is well-known that metals are emitted to the air by human activities and subsequently deposited to the land surface; however, we have not adequately evaluated the geographic extent and ecosystem impacts of industrial metal loading to soils. Here, we demonstrate that atmospheric inputs have widely contaminated soils with Mn in industrialized regions.(More)
Zhuang Jin Xu Gu decoction is a well-known traditional-chinese medicine prescriptionon. The present study investigated the effects of the serum level of calcitonin, the expressions of calcitonin receptor and core binding factor α1 in callus of femur fracture rats. The rats were randomly divided into shamoperated group, model group, control group and(More)
The purpose of this study is to demonstrate the feasibility of dynamic renal R2 /R2 '/R2 * measurements based on a method, denoted psMASE-ME, in which a periodic 180° pulse-shifting multi-echo asymmetric spin echo (psMASE) sequence, combined with a moving estimation (ME) strategy, is adopted. Following approval by the institutional animal care and use(More)
PURPOSE To demonstrate the feasibility of using a susceptibility-based magnetic resonance imaging (MRI) technique for measuring renal oxygen extraction fraction (OEF) changes under the influence of carbogen (97% O2 , 3% CO2 ) breathing. MATERIALS AND METHODS Eight New Zealand White rabbits were included in this study with local animal care committee(More)
Elevated levels of mercury in groundwater have been observed sporadically in aquifers world-wide. In some cases, groundwater is supersaturated with respect to elemental mercury [Hg (0)]. The mechanisms of Hg (0) formation in saturated sediments are currently poorly understood. The aim of this study is to evaluate the occurrence of biotic/abiotic reduction(More)
PURPOSE The purpose of this study was to demonstrate the feasibility of simultaneous dynamic R2 , R2', and R2* measurement of lower extremity muscle by means of a new method in which the periodic π pulse shifting multiecho asymmetric spin echo (psMASE) sequence is adopted together with a moving estimation (ME) strategy. THEORY AND METHODS The psMASE(More)
In this paper, the optical properties of gold nanorods (GNRs) tuned by lead sulfide (PbS) were studied. GNRs used in this work were synthesized by seed-mediated methods. Using electrostatic self-assembly methods, GNRs were modified by repetition of adsorbing oppositely charged polyelectrolyte. Then GNR-PbS nanostructure was fabricated by alternatively(More)
BACKGROUND To demonstrate the feasibility of using a susceptibility-based MRI technique with asymmetric spin-echo (ASE) sequence to assess the lower extremity muscle oxygen extraction fraction (OEF) alternations under cuff compression paradigm. METHODS Approved by the local institutional human study committee, nine healthy young volunteers participated in(More)
