Amelioration of Experimentally Induced Arthritis by Reducing Reactive Oxygen Species Production through the Intra-Articular Injection of Water-Soluble Fullerenol

Accumulated evidence suggests a pathogenic role of reactive oxygen species (ROS) in perpetually rheumatoid joints. Therefore, the application of radical scavengers for reducing the accumulation of ROS is beneficial for patients with rheumatoid arthritis (RA). We synthesized water-soluble fullerenols that could inhibit the production of ROS and applied intra-articular (i.a.) injection in an experimental arthritis… Continue reading Amelioration of Experimentally Induced Arthritis by Reducing Reactive Oxygen Species Production through the Intra-Articular Injection of Water-Soluble Fullerenol

Characterization of fullerenol-protein interactions and an extended investigation on cytotoxicity

Fullerenols, known as polyhydroxylated derivatives of fullerene, have attracted great attention due to their distinctive material properties and potential applications in biology and medicine. As a step toward the elucidation of basic behavior in biological systems, a variety of spectroscopic measurements as well as isothermal titration calorimetry (ITC) were applied to study the interaction between… Continue reading Characterization of fullerenol-protein interactions and an extended investigation on cytotoxicity

Fullerenol Nanoparticles Decrease Blood-Brain Barrier Interruption and Brain Edema during Cerebral Ischemia-Reperfusion Injury Probably by Reduction of Interleukin-6 and Matrix Metalloproteinase-9 Tra

Background:#nbsp;The present study aimed to examine the protective role of fullerenol nanoparticles against blood-brain barrier (BBB) interruption and brain edema during cerebral ischemia-reperfusion injury probably by reduction of interleukin-6 (IL-6) and matrix metalloproteinase-9 (MMP-9) transcription. Methods:#nbsp;The male Wistar rats (weighting 280-320 g) were randomly assigned into four groups as follows: sham, control ischemic, pretreated ischemic,… Continue reading Fullerenol Nanoparticles Decrease Blood-Brain Barrier Interruption and Brain Edema during Cerebral Ischemia-Reperfusion Injury Probably by Reduction of Interleukin-6 and Matrix Metalloproteinase-9 Tra

The antihyperlipidemic effects of fullerenol nanoparticles via adjusting the gut microbiota in vivo

Background:#nbsp;Nanoparticles (NPs) administered orally will meet the gut microbiota, but their impacts on microbiota homeostasis and the consequent physiological relevance remain largely unknown. Here, we describe the modulatory effects and the consequent pharmacological outputs of two orally administered fullerenols NPs (Fol1 C60(OH)7(O)8#nbsp;and Fol113 C60(OH)11(O)6) on gut microbiota. Results:#nbsp;Administration of Fol1 and Fol113 NPs for 4… Continue reading The antihyperlipidemic effects of fullerenol nanoparticles via adjusting the gut microbiota in vivo

Charging nanoparticles: increased binding of Gd@C 82(OH) 22 derivatives to human MMP-9

Unlike most matrix metalloproteinase (MMP) inhibitors, which target the conserved catalytic zinc site, Gd@C82(OH)22#nbsp;indirectly inhibits MMP-9 activity by binding at the ligand specificity S1′ loop. The allosteric binding makes Gd@C82(OH)22#nbsp;a promising inhibitor selective for MMP-9. However, the hydrophobic nature of the aromatic carbon cage may cause Gd@C82(OH)22#nbsp;to self-aggregate in aqueous solutions, hence weakening the binding.… Continue reading Charging nanoparticles: increased binding of Gd@C 82(OH) 22 derivatives to human MMP-9

Evaluation of the influence of fullerenol on aging and stress resistance using Caenorhabditis elegans

Fullerene derivatives have attracted extensive attention in biomedical fields and polyhydroxyl fullerene (fullerenol), a water-soluble fullerene derivative, is demonstrated as a powerful antioxidant. To further assess their anti-aging and anti-stress potential, we employed Caenorhabditis elegans (C. elegans) as a model organism to evaluate the effects of fullerenol on the growth, development, behavior and anti-stress ability… Continue reading Evaluation of the influence of fullerenol on aging and stress resistance using Caenorhabditis elegans

The prolongation of the lifespan of rats by repeated oral administration of [60]fullerene

Countless studies showed that [60]fullerene (C(60)) and derivatives could have many potential biomedical applications. However, while several independent research groups showed that C(60) has no acute or sub-acute toxicity in various experimental models, more than 25 years after its discovery the in vivo fate and the chronic effects of this fullerene remain unknown. If the… Continue reading The prolongation of the lifespan of rats by repeated oral administration of [60]fullerene

Anti-aging effect of fullerenol on skin aging through derived stem cells in a mouse model

Fullerenol is similar to graphite in terms of structure. In the present study, the anti-aging effect of fullerenol on skin through derived stem cells in a mouse model was assessed and the potential mechanism of fullerenol was investigated. The anti-aging effect of fullerenol effectively inhibited the retention rate of transplanted adipose-derived stem cells and increased… Continue reading Anti-aging effect of fullerenol on skin aging through derived stem cells in a mouse model

Metallofullerene nanoparticles promote osteogenic differentiation of bone marrow stromal cells through BMP signaling pathway

Although endohedral metallofullerenol [Gd@C(82)(OH)(22)](n) nanoparticles have anti-tumor efficiency and mostly deposit in the bones of mice, how these nanoparticles act in bone marrow stromal cells (MSCs) remains largely unknown. Herein, we observed that [Gd@C(82)(OH)(22)](n) nanoparticles facilitated the differentiation of MSCs toward osteoblasts, as evidenced by the enhancement of alkaline phosphatase (ALP) activity and mineralized nodule… Continue reading Metallofullerene nanoparticles promote osteogenic differentiation of bone marrow stromal cells through BMP signaling pathway
