Tyrosinase is the first and rate limiting enzyme in the synthesis of melanin pigments for coloring hair, skin, and eyes. As reported in this study, a natural product, (-)-N-formylanonaine isolated from the leaves of Michelia alba D.C. (Magnolianceae), was found to inhibit mushroom tyrosinase with an IC50 of 74.3 microM and to have tyrosinase and melanin(More)
Personal Health Record systems (PHRs) provide opportunities for patients to access their own PHR. However, PHRs are teeming with medical terminologies, such as disease and symptom names, etc. Patients need readily understandable and useful health knowledge in addition to their records in order to enhance their self-care ability. This study describes a(More)
Skin wound healing is an important lifesaving issue for massive lesions. A novel porous scaffold with collagen, hyaluronic acid and gelatin was developed for skin wound repair. The swelling ratio of this developed scaffold was assayed by water absorption capacity and showed a value of over 20 g water/g dried scaffold. The scaffold was then degraded in time-(More)
We present our work on face detection and pose estimation from hyperspectral imagery. The long-term goal of our research is to explore the use of hyperspectral imagery for building an automated system for human recognition. We report our preliminary results obtained with the face detection algorithm proposed by Paul Viola and Michael Jones. The algorithm(More)
In a free of charge or flat-rate Internet access environment, there often exists abusive and unfair usage of network resources. In this paper, the Internet access by the dormitory users at the National Taiwan University (NTU) serves as a conveyer problem. A quota-based service architecture combined with priority scheduling is developed to resolve the(More)
Nonsyndromic orofacial cleft is a common birth defect with a complex etiology, including multiple genetic and environmental risk factors. Recent whole genome analyses suggested associations between nonsyndromic orofacial cleft and up to 18 genetic risk loci (ABCA4, BMP4, CRISPLD2, GSTT1, FGF8, FGFR2, FOXE1, IRF6, MAFB, MSX1, MTHFR, MYH9, PDGFC, PVRL1,(More)
Human skin protects the body from mechanical and chemical damages, and skin wound healing is a costly procedure and worldwide issue. A Zingiber officinale compound, 6-dehydrogingerdione (6-DG), is presented as a novel biofunctional healing agent for human skin wound repair. The effectiveness on cell growth/migration, growth factor, collagen amount, and(More)
