Positively charged superparamagnetic iron oxide nanoparticle (SPION)-loaded polymersome was prepared in order to deliver genes to the target sites, which was monitored by magnetic resonance imaging (MRI), concomitantly. The transfection efficiency in vitro was tested by treating CT-26 colon cancer cell line with luciferase-expressing plasmids/SPION complex.(More)
UNLABELLED In this study, we prepared iron oxide nanoparticle and doxorubicin-loaded multifunctional nano-carrier (IONP/DOX-MFNC), capable of simultaneous cancer targeting via a herceptin monoclonal antibody, controlled anticancer drug delivery, as well as imaging modalities of magnetic resonance imaging (MRI) and near-infrared fluorescence (NIRF) imaging.(More)
This paper presents a human region segmentation algorithm for real-time video-call applications. Unlike conventional methods, the segmentation process is automatically initialized and the motion of cameras is not restricted. To be precise, our method is initialized by face detection results and human/background regions are modeled with spatial color(More)
To achieve a sufficient targeting efficiency and prolonged half-life in-vivo, the physicochemical parameters including size and surface chemistry of therapeutic and imaging agents should be controlled. In this study, we prepared an iron oxide nanoparticle (IONP)-loaded, functional nano-carrier with different loading contents to modulate the mechanical(More)
This paper presents a new region-of-interest(ROI) based compression scheme for video call applications in a preprocessing manner. In our application, ROI is the human region which is detected by a human/background segmentation method, and perceptually less important details are removed by applying the edge-preserving spatio-temporal filter to the background(More)
This paper presents a new level set tracking method for the tracking of non-rigid objects in videos. The main idea is to introduce a new probabilistic model to classify the background and object more robustly, which is then encoded as a new term for the energy function for solving the level set problem. Also, we propose to use bounding box of the contour as(More)
