Anti-drilling Characteristic Predicting Method for Penglai Gas Area Based on Meso Characteristic of Stone
Recently years, the rate of penetration (ROP) of Xujiahe sequence of upper tertiary (13 1/8in” bores) among prospecting wells in Penglai gas area was too slow, and the difficulty in coring also constrained the pr...

Open AccessOrally administered gold nanoparticles protect against colitis by attenuating Toll-like receptor 4- and reactive oxygen/nitrogen species-mediated inflammatory responses but could induce gut dysbiosis in mice
Gold nanoparticles (AuNPs) are attracting interest as potential therapeutic agents to treat inflammatory diseases, but their anti-inflammatory mechanism of action is not clear yet. In addition, the effect of o...

Differential genotoxicity mechanisms of silver nanoparticles and silver ions
In spite of many reports on the toxicity of silver nanoparticles (AgNPs), the mechanisms underlying the toxicity are far from clear. A key question is whether the observed toxicity comes from the silver ions (Ag+

Probing hydroxyl radical generation from H2O2 upon plasmon excitation of gold nanorods using electron spin resonance: Molecular oxygen-mediated activation
Gold nanostructures are among the noble metal nanomaterials being intensely studied due to their good biocompatibility, tunable localized surface plasmon resonance (SPR), and ease of modification. These proper...

Open AccessIntravenous administration of silver nanoparticles causes organ toxicity through intracellular ROS-related loss of inter-endothelial junction
Administration of silver nanoparticles (AgNPs) to mice could result in their distribution and accumulation in multiple organs, with notable prominence in liver, lungs, and kidneys. However, how AgNPs transport...

Open AccessEnhancement of Paramagnetic Relaxation by Photoexcited Gold Nanorods
Electron spin resonance (ESR) spectroscopy was used to investigate the switchable, light-dependent effects of gold nanorods (GNRs) on paramagnetic properties of nitroxide spin probes. The photoexcited GNRs enh...

Open AccessThe contributions of metal impurities and tube structure to the toxicity of carbon nanotube materials
Due to the existence of considerable quantities of metallic and carbonaceous impurities, the key factor and mechanism for the reported toxicity of carbon nanotubes (CNTs) are unclear. Here, we first quantify t...

The effects of ginsenoside Rb1 on JNK in oxidative injury in cardiomyocytes
Reactive oxygen species (ROS) can induce oxidative injury via iron interactions (i.e. Fenton chemistry and hydroxyl radical formation). Our prior work suggested that American ginseng berry extract and ginsenoside...

Disruption of microfilaments by cytochalasin B decreases accumulation of cisplatin in human epidermal carcinoma and liver carcinoma cell lines
Although cisplatin is a frequently used cancer chemotherapeutic drug, its effectiveness is hindered by the development of resistance in cancer cells. In order to understand the reason(s) for this resistance, t...

American ginseng berry extract and ginsenoside Re attenuate cisplatin-induced kaolin intake in rats
Cisplatin, a chemotherapeutic agent, causes significant nausea and vomiting. It is postulated that cisplatin-induced oxidant stress may be responsible for these symptoms. We tested whether pretreatment with Am...

Effects of conjugated linoleic acid on oxygen diffusion-concentration product and depletion in membranes by using electron spin resonance spin-label oximetry
The effect of conjugated linoleic acid (CLA) on the relation between structure and function of membranes is described in this paper. Electron spin resonance (ESR) spin-label oximetry was used in the present st...
