Osteoarthritis (OA) is a major disability of elderly people. Sesamin is the main compound in Sesamun indicum Linn., and it has an anti-inflammatory effect by specifically inhibiting Δ5-desaturase in polyunsaturated fatty acid biosynthesis. The chondroprotective effects of sesamin were thus studied in a porcine cartilage explant induced with(More)
BACKGROUND Glucosamine (GlcN) is a well-recognized candidate for treatment of osteoarthritis. However, it is currently used in derivative forms, such as glucosamine-hydrochloride (GlcN-HCl) or glucosamine sulfate (GlcN-S). However, the molecular mode of action remains unclear. In this study, we compared the effects of Glucose (Glc), Glucuronic acid (GlcA),(More)
Osteoarthritis (OA) is the most common form of arthritis and affects millions of people worldwide. Patients have traditionally been treated with non-steroidal anti-inflammatory drugs (NSAIDs), but these are associated with significant side effects. Purification of the acetone extract of Alpinia galanga afforded p-hydroxycinnamaldehyde, as identified by(More)
Interleukin-1β (IL-1β) induces the expression of matrix metalloproteinases (MMPs) implicated in cartilage and joint degradation in osteoarthritis (OA) and rheumatoid arthritis (RA). Polyoxypregnane glycoside (PPG), active compound was identified from Dregea volubilis extract by chemical analysis, shown to exert chondroprotective effects in cartilage explant(More)
BACKGROUND Cartilage tissue engineering offers new strategies in repairing damaged cartilage. Scaffolds have been used for the in vitro and in vivo procedures for this application, which demonstrates the compatible biological and physical properties that mimic natural tissues. Several types of scaffolds were used and had different effects on cell functions.(More)
BACKGROUND Rheumatoid arthritis (RA) is an autoimmune disease associated with chronic inflammatory arthritis. TNF-α and OSM are pro-inflammatory cytokines that play a key role in RA progression. Thus, reducing the effects of both cytokines is practical in order to relieve the progression of the disease. This current study is interested in sesamin, an active(More)
Osteoarthritis (OA) is the most common form of arthritis. Obesity has been believed to be an important risk factor for OA development and the progression of not only load-bearing joints, but low-load-bearing joints as well. Increased leptin has been the focus of a link between obesity and OA. In this study, the effects of pathological (100ng/ml) or(More)
The promotional nature of sesamin on human osteoblast differentiation has been proven. Here, the effect of sesamin on human osteoclasts was investigated in terms of differentiation and function in M-CSF and RANKL induced human PBMCs. Sesamin treatment significantly decreased the number of differentiated osteoclasts observed by TRAP staining; however,(More)
Osteoarthritis is a degenerative joint disease in which interleukin-1β plays a major role in the inflammatory process. Administration of collagen hydrolysate was an optional treatment of osteoarthritis. Fish has become an interesting source of collagen hydrolysate because of religious reason and there is no risk from mad cow disease. However, the effects of(More)
OBJECTIVE To investigate the biological effects of the Mucuna pruriens (M. pruriens) seed extracts that lacked l-DOPA, which was formerly reported as the active ingredient, on erectile dysfunction (ED) both in vitro and in vivo. METHODS Seed of M. pruriens plant that cultivated in Mae Taeng District, Chiang Mai Province, Thailand, was collected. Component(More)
