A sensitive sensor for lead(II) in water is based on peat moss embedded in the carbon paste...Reports on a study by researchers H.Yao and G.J. Ramelow on the performance of electrodes containing Sphagnum spp. moss (peat moss), which is a common lichen. Information on pH-sensitive metal ion ...
The solubility of lead (II) chloride (PbCl2) is 1.6 × 10-2 M. What is the Ksp of PbCl2A.5.0 × 10-4B.4.1 × 10-6C.3.1 × 10-7D.1.6 × 10-5E.1.6 × 10-2 相关知识点: 试题来源: 解析 D 该题考察动词搭配。句子意为“外面很冷,你最好把夹克拉上”。选项中只有“zip...
For volatile organic compounds (VOCs) to be released from the plant cell into the atmosphere, they have to cross the plasma membrane, the cell wall, and the cuticle. However, how these hydrophobic compounds cross the hydrophilic cell wall is largely unkn
Owing to the PEG constituting the outer shell of the micelles, NK105 is soluble in water. In addition, PEG also confers a stealth property to the formulation, that allows the micellar drug preparation to be less avidly taken up by the reticuloendothelial system (RES) and to be retained in...
These experiments show that a notable proportion of the cytoplasmic and soluble nuclear ERα is bound to poly(A) RNAs in MCF7 and T47D ERα+ breast cancer cell lines (Figure 1A). ERα association with RNA is also evident in human breast tumor samples and is significantly higher than ...
WST water-soluble tetrazolium Wt wild-type Summary Targets and medical approaches to prevent progression of chronic liver disease to liver fibrosis or cirrhosis are urgently needed. We describe p70S6K being dysregulated in human liver fibrosis and define this protein as checkpoint of human hepatic stel...
Therefore, it is plausible that only the water-soluble components of CS and a small part of the particulate matter contribute to the toxicity of these preparations. According to our method, the toxic substances in the gaseous phase of CS that are supplied to cells are diluted in a measured ...

Soluble Aβ oligomer has been determined to be much more toxic than mature fibrils or plaques, and is widely regarded as the main neurotoxin in the progress of AD [6]. The inhibition of Aβ aggregates, and soluble Aβ oligomer in particular, therefore, might be a therapeutic mechanism for...
We analysed the effects of genistein on cell number and cell cycle progression (flow cytometric analysis of propidium iodide-stained nuclei) of human breast cancer cells (MCF-7) in vitro. Genistein produced a significant, dose-dependent inhibition of MCF-7 cell growth with an ID50 of ...
