The Hough transform has been a frequently used method for detecting lines in images. However, when applying Hough transform and derived algorithms using the standard Hough voting scheme on real-world images, the methods often suffer considerable degeneration in performance, especially in detection rate, because of the large amount of edges given by complex(More)
Osteoarthritis (OA) is a chronic, incurable and destructive joint disease that is characterized by chondrocyte hypertrophy and cartilage degradation. Angiogenesis, mediated by the action of vascular endothelial growth factor (VEGF), is known to be a contributing factor in the pathogenesis of OA. In this study, we use a lentivirus-based approach to(More)

The proposed approach is(More)
Periodontitis is an inflammatory disease that causes osteolysis and tooth loss. It is known that the nuclear factor kappa B (NF-κB) signalling pathway plays a key role in the progression of inflammation and osteoclastogenesis in periodontitis. Parthenolide (PTL), a sesquiterpene lactone extracted from the shoots of Tanacetum parthenium, has been shown to(More)
