Results. Gold(III) porphyrin 1a induces apoptosis in cancer cells. We have shown in earlier studies that gold(III) porphyrin 1a induced apoptosis in human cervix epitheloid carcinoma cells and SUNE1 cell line (nasopharyngeal carcinoma; article accepted by Proteomics).In the present study, we compared the cytotoxicity of gold(III) porphyrin 1a in four nasopharyngeal carcinoma cell lines (HONE1 ...
A previous study suggested that gold nanoparticles induce autophagosome accumulation through size‐dependent nanoparticle uptake. 17 However, in this study, the cellular uptake efficiencies of these three NBP/TiO 2 samples were similar, as indicated by intracellular gold …
Although vascular disrupting agents (VDAs) have been extensively implemented in current clinical tumor therapy, the notable adverse events caused by long-term dosing severely limit the therapeutic efficacy. To improve this therapy, we report a strategy for VDA-induced aggregation of gold nanoparticles to further destroy tumor vascular by photothermal effect.
Mar 21, 2013· Many alluvial placer deposits around the world occur in river systems that have been affected by tectonic events, causing drainage reorientation and severance of links between placers and their sources. This study documents tectonic rejuvenation of topography in the Otago giant placer goldfield, New Zealand, which has resulted in numerous river capture and drainage reorientation events.
Sep 22, 2011· The rats exposed to aerosols of GNPs revealed that the NPs were rapidly taken into the system with the highest accumulation in the lungs, aorta, esophagus and olfactory bulb .Moreover, NPs are believed to be more biologically reactive than their bulk counter parts due to their small size and larger surface area to volume ratio [1, 2].Although some scientists consider NPs as nontoxic, there ...

autophagosome accumulation ability (Figure 2d) and induced much greater LC3-II conversion and p62 accumulation in U-87 MG cells (Figure 2e). A previous study suggested that gold nan-oparticles induce autophagosome accumulation through size-dependent nanoparticle uptake. However, in this study, the Adv. Sci. 2018, 5, 1700585
Successful treatment of brain tumors such as glioblastoma multiforme (GBM) is limited in large part by the cumulative dose of Radiation Therapy (RT) that can be safely given and the blood-brain barrier (BBB), which limits the delivery of systemic anticancer agents into tumor tissue. Consequently, the overall prognosis remains grim. Herein, we report our pilot studies in cell culture ...

Lung tissue sections from smokers with COPD exhibited significant p62 accumulation as lung function declined in subjects with severe emphysema–COPD (S, GOLD III–IV versus S and NS, GOLD 0–I), demonstrating increase in CS-induced autophagy impairment with COPD–emphysema progression.
We report a "smart" gold nanoparticle that is designed to aggregate in mild acidic intracellular environments by its hydrolysis-susceptible citraconic amide surface. With a relatively small size of 10 nm, the "smart" gold nanoparticles can be efficiently internalized into cancerous cells. Triggered by pH change, the nanoparticle surfaces are engineered to have both positive and negative charges.
The relevance of this finding is, however, unclear since uncomplicated gold therapy also results in gold accumulation in many organs, especially in cells of the reticuloendothelial system in the liver and kidney 10, 11) In previous reports, therapy for gold-induced hepatotoxicity has always consisted of discontinuation of the drug.
Gold colloids occur in black smoker fluids from the Niua South hydrothermal vent field, Lau Basin (South Pacific Ocean), confirming the long-standing hypothesis that gold may undergo colloidal transport in hydrothermal fluids. Six black smoker vents, varying in temperature from 250 °C to 325 °C, were sampled; the 325 °C vent was boiling at the time of sampling and the 250 °C fluids were ...
devices. We report the direct detection of spin accumulation at the free surface of nonmagnetic metal ﬁlms using magnetization-induced optical surface second harmonic generation. The technique is applied to probe the current induced surface spin accumulation in various heavy metals such as Pt, b-Ta, and Au with high sensitivity.
External stimuli, such as ultrasound, magnetic field, and light, can be applied to activate in vivo tumor targeting. Herein, we fabricated polymer encapsulated gold nanorods to couple the photothermal properties of gold nanorods and the thermo- and pH-responsive properties of polymers in a single nanocomposite. The activation mechamism was thus transformed from heat to near-infrared (NIR ...
Despite intensive research activities in the field of laser-induced periodic surface structures (LIPSS), the large-area nanostructuring of glasses is still a challenging problem, which is mainly caused by the strongly non-linear absorption of the laser radiation by the dielectric material. Therefore, most investigations are limited to single-spot experiments on different types of glasses.
The data on the biocompatibility of naked gold nanoparticles (GNPs) are scarce, and their interpretation is controversial. We studied the acute (1 day) and subchronic (5 days) effects of GNPs (10 and 50 nm diameter) on expression of interleukin-1 beta (IL-1 β ), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF- α) in the liver and kidneys of rats.
B. juncea induced with KCN showed maximum gold accumulation of 92 mg/kg (in leaves and root). C. intybus also gave maximum accumulation of 164 mg/kg Au (in the whole plant) with KCN. Significant gold accumulation into the B. juncea and Z. mays in the greenhouse environment has been reported by Anderson et al. (2005).

View/Open Full Text viewcontent.pdf (106.4Kb) Abstract In this study the growth stubstrate of the plants Brassica juncea, Berkheya coddii and chicory were amended with thiocyanate and cyanide solutions to induce uptake and the gold concentrations in the ...
This paper examines the effects of ionic gold on Saccharomyces cerevisiae, as determined by long-term (growth in gold-containing media) and short-term interactions (H+ efflux activity). An increasing gold concentration inhibited growth and at <0.2 mM Au, growth was not observed. Transmission electron microscopy revealed no differences in ultrastructure but fine electron dense particles were ...

The advanced gold accumulator can be equipped in ...
The induced accumulation of gold NPs was also studied (Lamb et al., 2001). Additionally, Beattie and Haverkamp (2011) studied the synthesis of silver and gold NPs in cells of B. juncea ...
Drug-induced pigmentation of the skin may occur as a consequence of drug administration, and the mechanism may be postinflammatory hyperpigmentation in some cases, but frequently is related to actual deposition of the offending drug in the skin.: 125–6 The incidence of this change varies, and depends on the type of medication involved.
However, at Niua, the formation of gold particles on the snorkel tarnish, the elevated concentration of gold in the boiled chimney, the undersaturation of Au in pre-boiled fluids (Fig. DR5), and the transport of particulate gold in boiling, focused, and diffuse flow fluids, suggest that the precipitation at Niua is boiling induced…
Sensory neurons are particularly susceptible to neuronal damage in diabetes, and silent mating type information regulation 2 homolog 1 (Sirt1) has been recently identified as a key gene in neuroprotection and wound healing. We found that the expression of Sirt1 was downregulated in trigeminal sensory neurons of diabetic mice. A microRNA microarray analysis identified microRNA-182 (miR-182) as ...

Results. The synthetic gold(III) dithiocarbamate compound 2 inhibits proliferation of various breast cancer cell lines. Recently, four different gold(III) dithiocarbamate derivatives (compounds 1-4) were reported to induce cell death in several human tumor cell lines ( 2).These compounds were also shown to interact with DNA in a weak and reversible manner, suggesting that DNA is not their ...
The gold accumulator is a reward from the Dungeoneering skill. It initially costs 20,000 tokens, increasing by 20,000 tokens for each purchase, up to a maximum of 60,000 tokens per purchase. The gold accumulator is also a possible reward from the dungeoneering chest in The Faraway Place where Things are Kept. Only one accumulator can be owned at a time.
Jan 25, 2012· Nanoparticles (NPs) can potentially cause adverse effects on organ, tissue, cellular, subcellular and protein levels due to their unusual physicochemical properties. Advances in nanotechnology have identified promising candidates for many biological and biomedical applications. Since the properties of NPs differ from that of their bulk materials, they are being increasingly …
