Nowadays, non-invasive blood pressure (BP) is commonly measured by cuff-based devices, which cause discomfort during measurement and can only provide snapshots of BP. In order to measure beat-to-beat BP continuously and cufflessly, models based on pulse arrival time (PAT) and RR interval (RRI), which can both be conveniently acquired by wearable devices,(More)
The aging population, prevalence of chronic diseases, and outbreaks of infectious diseases are some of the major challenges of our present-day society. To address these unmet healthcare needs, especially for the early prediction and treatment of major diseases, health informatics, which deals with the acquisition, transmission, processing, storage,(More)
24-h blood pressure (BP) has significant prognostic value for cardiovascular risk screening, but the present BP devices are mainly cuff-based, which are unsuitable for long-term BP measurement, especially during nighttime. In this paper, we developed an armband wearable pulse transit time (PTT) system for 24-h cuff-less BP measurement and evaluated it in an(More)
In many neurodegenerative disorders that lead to memory loss and dementia, the brain pathology responsible for neuronal loss is marked by accumulations of proteins in the form of extracellular plaques and intracellular filamentous tangles, containing hyperphosphorylated cytoskeletal proteins. These are assumed to arise as a consequence of deregulation of a(More)
The gene encoding isocitrate dehydrogenase (IDH) is somatically mutated predominantly in secondary glioblastoma multiforme. Glioma-specific mutations in IDH1 always produced a single amino acid substitution at R132, but mutations in IDH2 were exclusively at R172 which was the analogous site to R132 in IDH1. Mutations of IDH1 and IDH2 led to simultaneous(More)
Development of glioma-specific nanoparticles has been an area of intense research over the past several years. Iron oxide, multifunctional superparamagnetic, and NaYF(4):Yb,rare-earth upconversion nanoparticles, conjugated with chlorotoxin (CTX, a key toxin in scorpion venom which has been shown to bind specifically to glioma cell surface as a specific(More)
We propose a dimensionality reduction technique in this paper, named Orthogonal Isometric Projection (OIP). In contrast with Isomap, which learns the low-dimension embedding, and solves problem under the classic Multidimensional Scaling (MDS) framework, we consider an explicit linear projection by capturing the geodesic distance, which is able to handle new(More)
Cyclin-dependent kinase 5 (cdk5), a member of the cyclin-dependent kinase family, is expressed predominantly in post-mitotic cell populations. Unlike the other cdks, cdk5 is abundant and most active in differentiated neurons. Here, we describe the function of a cdk5 ortholog in zebrafish. Cdk5 catalytic activity is meager but present in early stages of(More)
The gene encoding isocitrate dehydrogenase (IDH) is somatically mutated predominantly in secondary glioblastoma multiforme. Mutations of IDH1 and IDH2 lead to simultaneous loss and gain of activities in the production of α-ketoglutarate and 2-hydroxyglutarate, respectively. Lithium chloride was recently proved efficient in inhibiting glioma cell migration.(More)
