Ischemic stroke is caused by the interruption of cerebral blood flow that leads to brain damage with long-term sensorimotor deficits. Stem cell transplantation may recover functional deficit by replacing damaged brain. In this study, we attempted to test whether the human neural stem cells (NSCs) can improve the outcome in the rat brain with intravenous(More)
While many non-destructive ultrasonic signal test scenarios involve very shallow surfaces, signals for testing shafts are long and the new problem of mode-converted reflection emerges. They are echoes that do not correspond to cracks in the material, neither to characteristics of the shaft. Also, the length of the signals demands the application of(More)
The ordered order-k Voronoi diagram is a popular generalization of the ordinary Voronoi diagram modeling ordered k nearest sites. Despite of the usefulness of the ordered order-k Voronoi diagram, its structural complexity and wealth of information captured result in poor readability. Most research has focused on computational complexity, and(More)
An animal model induced by striatal quinolinic acid (QA) injection shows ongoing striatal degeneration mimicking Huntington's disease. To study the migratory ability and the neuroprotective effect of human neural stem cells (NSCs) in this model, we transplanted NSCs (5 x 10(6)) or saline intravenously at 7 days after unilateral QA injection. NSCs-group(More)
A loss of neostriatal neurons is a characteristic of Huntington's disease (HD), and neural tissue transplantation has been performed directly into the striatum. Since the neural stem cells have ability to migrate into the lesion site, we administered immortalized neural stem-like cells (NSC) into the ventricle or via a tail vein following unilateral(More)
With the development of web technique and social network sites human now can produce information, share with others online easily. Photo-sharing website, Flickr, stores huge number of photos where people upload and share their pictures. This research proposes a framework that is used to extract associative points-of-interest patterns from geo-tagged photos(More)
In many applications of machine learning a series of feature extraction approaches and a series of classifiers are explored in order to obtain a system with the highest accuracy possible. In the application we discussed here at least two feature extraction approaches have been explored (Fast Fourier Transform) and Discrete Wavelet Transform, and at least(More)
Burkitt lymphoma (BL) is a tumor with the characteristics of germinal center B cells. We previously reported that the CM1 (centrocyte/-blast marker 1) molecule is expressed only in germinal center B cells, specifically, in a subpopulation of centroblasts and centrocytes. In the present study, we investigated the apoptosis induced by anti-CM1 in the Ramos(More)
