Colorectal cancer (CRC) is one of the most common cancers world-wide, with highest incidence rates in western countries. In recent years, much effort has been dedicated in search for natural or pharmacological preventive agents, which would block or attenuate CRC process. In search for new pharmacological agent, the effects of fullerenol C60 (OH)24 nano particles (FNP) on liver oxidative status and promotion or progression phase of colorectal carcinogenesis in dimethylhydrazine-induced rat model of CRC were investigated. Our results demonstrate that FNP effectively inhibited formation of dysplastic aberrant crypt foci, which are regarded as early histopathological lesions in the pathogenesis of CRC. FNP treatment also improved activity of antioxidant enzymes in the liver.

The purpose was to examine the anti-tumor and antimetastatic activities of fullerenol andtheirrelatedmechanisms.ThirtyEMT-6tumor-bearingmicewereinjectedintraperitoneallywith 0.1 ml saline or 0.1 ml saline containing fullerenol C 60 (OH) 20 (0.08 and 0.4 mg/ml) dailyfor 16 days. Using tumor tissues, we investigated imbalances in the oxidative defense sys-tem and the expression of several angiogenesis factors. C 60 (OH) 20 exhibits anti-tumor andantimetastatic activities in EMT-6 breast cancer metastasis model. Treatment withC 60 (OH)20 was found to modulate oxidative stress significantly. The expression of severalangiogenesis factors was reduced in tumor tissues after treatment with fullerenol.

The aim of this study is to detect the effects of C60 fullerenes, which possess pronounced antioxidant properties, in comparison with the actions of the known exogenous antioxidants N-acetylcysteine (NAC) and β-Alanine in terms of exercise tolerance and contractile property changes of the m. triceps surae (TS) during development of the muscle fatigue in rats. 

Oral C60FAS administration clearly demonstrated an action on skeletal muscle fatigue development similar to the effects of i.p. injections of the exogenous antioxidants NAC or β-Alanine. This creates opportunities to oral use of C60FAS as a potential therapeutic agent. Due to the membranotropic activity of C60 fullerenes, non-toxic C60FAS has a more pronounced effect on the prooxidant-antioxidant homeostasis of muscle tissues in rats.

Olive Oil vs. Sunflower Oil

The first cohort applied six drops of olive oil to one forearm twice daily for 5 weeks. The second cohort applied six drops of olive oil to one forearm and six drops of sunflower seed oil to the other twice daily for 4 weeks. The effect of the treatments was evaluated by determining stratum corneum integrity and cohesion, intercorneocyte cohesion, moisturization, skin-surface pH, and erythema. Topical application of olive oil for 4 weeks caused a significant reduction in stratum corneum integrity and induced mild erythema in volunteers with and without a history of atopic dermatitis. Sunflower seed oil preserved stratum corneum integrity, did not cause erythema, and improved hydration in the same volunteers. In contrast to sunflower seed oil, topical treatment with olive oil significantly damages the skin barrier, and therefore has the potential to promote the development of, and exacerbate existing, atopic dermatitis. The use of olive oil for the treatment of dry skin and infant massage should therefore be discouraged. 

Assembly of C 60 Fullerene in Water and Toluene

This work aims at assessing the influence of two different solvents, bidistilled water and toluene, on dispersions of carbon-based engineered nanomaterials, namely, fullerenes, and their self-assembly behavior…. Aggregates obtained in toluene showed a well-formed crystal structure. When using water, the obtained aggregates were amorphous and showed a no well-defined shape. Their sizes ranged between 20 and 40 nm for nanosized structures and between 0.4 and 4.8 μm for micron-sized self-aggregates.
