In this paper, we propose a robust surface reconstruction algorithm from the gradient field by minimizing the absolute error between the input and estimated gradient field from the reconstructed surface. The resulting L1 norm based cost function can then be efficiently solved via linear programming. Compared to conventional L2 estimation algorithms, the(More)
For majorities of no-reference image quality assessment (NRIQA) algorithms, prior knowledge about image distortion types is needed. However, the source distortions in the image are actually not given in most cases. In this paper, we propose a no-reference image quality assessment approach based on steerable pyramid decomposition using natural scene(More)
PURPOSE The purpose of this study was to determine if a combination chemotherapy, using continuous intravenous infusion of fluorouracil (5-FU) in combination with split-dose cisplatin, in patients with recurrent or metastatic head and neck squamous-cell could improve previously reported clinical outcomes. METHODS Forty-two patients with recurrent or(More)
Informal electronic waste (e-waste) recycling results in serious environmental pollution of polybrominated diphenyl ethers (PBDEs) and heavy metals. This study explored whether there is an association between PBDEs, heavy metal and key growth- and development-related hormones in children from Guiyu, an e-waste area in southern China. We quantified eight(More)
Electronic waste recycling produces Polycyclic Aromatic Hydrocarbons (PAHs) and Polybrominated Diphenyl Ethers (PBDEs) which may affect fetal growth and development by altering the insulin-like-growth factor (IGF) system. Questionnaires were administered to pregnant women (Guiyu, an e-waste site, n = 101; control, n = 53), and umbilical cord blood (UCB) and(More)
In utero co-exposure to endocrine disrupting compounds can perturb fetal development. However, the effect of co-exposure on pivotal regulatory genes has seldom been investigated. We explored the effects of in utero co-exposure to cadmium (Cd), bisphenol A (BPA) and polychlorinated biphenyls (PCBs) on master regulator genes. We recruited 284 healthy pregnant(More)
Informal e-waste recycling activities results in serious environmental pollution of PAHs. We evaluated the body burden of 16 PAH congeners and potential health risks for children. A total of 167 children from exposed and reference area entered this study. Child blood samples were collected; height, weight, head and chest circumferences were measured. Blood(More)
Cambogin is a polycyclic polyprenylated acylphoroglucinol (PPAP) from the Garcinia genus, which has been used traditionally for cancer treatment across Southeastern Asia. In this study, we found that cambogin inhibited breast cancer cell proliferation and induced cell apoptosis in vitro. Cambogin induced the activation of the caspase-independent(More)
