Although the pharmacology and clinical application of water extracts of Ganoderma lucidum have been extensively documented, little is known regarding its alcohol extract. In the present study, the anti-tumor effect of an alcohol extract of Ganoderma lucidum was investigated using MCF-7 cells. We found that the alcohol extract of Ganoderma lucidum inhibited(More)
Dimethyl sulfoxide (DMSO) is an FDA-approved organosulfur solvent that is reported to have therapeutic value in osteoarthritis and osteopenia. DMSO is used as a cryoprotectant for the cryopreservation of bone grafts and mesenchymal stem cells which are later used for bone repair. It is also used as a solvent in the preparation of various scaffolds used for(More)
BACKGROUND The existence of fibrocartilage, bone-like tissues, nerves, and blood vessels in the anulus fibrosus during intervertebral disc degeneration has been well documented. Migration of differentiated cells from outside the intervertebral disc has been hypothesized as a possible mechanism for the formation of these tissues. We hypothesized that the(More)
Symptomatic intervertebral disc degeneration is associated with several spinal diseases, which cause losses of life quality and money. Tissue engineering provides a promising approach to recover the functionality of the degenerative intervertebral disc. Most studies are directed toward nucleus pulposus (NP) tissue engineering because disc degeneration is(More)
The biological activities of fullerenes have attracted extensive attention in recent years. The aim of this paper is to study the relation of the photo-induced cytotoxicity of fullerene derivatives to their chemical structures as well as the possible cellular mechanism involved in the photocytotoxicity. Three C(60) derivatives with two to four malonic acid(More)
This work reported the design, preparation and characterization of functional hollow polymer nanoparticles with S-nitrosothiol (SNO) as scaffolds for nitric oxide (NO) release in PBS buffer and bovine serum. The thiolated hollow polymer nanoparticles were prepared by distillation precipitation polymerization of ethyleneglycol dimethacrylate (EGDMA) and(More)
Both Sjögren's syndrome and therapeutic irradiation for head and neck cancer lead to irreversible damage of the parenchyma of the salivary glands. This report describes an attempt to grow miniature pig (minipig) parotid gland cells on artificial films and tubular scaffolds with the ultimate intention of developing bio-engineered replacement tissue. Minipig(More)
Using human erythrocyte membranes (EMs) as a model system, we have examined photo-induced lipid peroxidation by a bis-methanophosphonate fullerene (BMPF) and four other fullerene derivatives including a mono-methanophosphonic acid fullerene (MMPF), a dimalonic acid C(60) (DMA C(60)), a trimalonic acid C(60) (TMA C(60)) and a polyhydroxylated fullerene(More)
Increased oxidative stress is currently considered as a crucial cause of corticosteroid-induced osteonecrosis. The aim of this study was to evaluate the effect of fullerol, a powerful antioxidant, on adipogenic and osteogenic differentiation of a mouse bone marrow derived multipotent cell line, D1. Upon treatment with dexamethasone, D1 cells containing(More)
Fullerenes are among the strongest antioxidants and are characterized as "radical sponges." The research on biomedicinal applications of fullerenes has achieved significant progress since the landmark publication by Friedman et al in 1993. Fullerene-biomolecule conjugates have become an important area of research during the past 2 decades. By a thorough(More)
