Current bio-medical imaging researches aim to detect brain micrometastasis in early stage for its increasing incidence and high mortality rates. Synchrotron phase-contrast imaging techniques, such as in-line phase-contrast (IPC) and grating-based phase-contrast (GPC) imaging, could provide a high spatial and density imaging study of biological specimens' 3D structures. In this study, we demonst...
The Generalized Phase Contrast (GPC) method of optical 3D manipulation has previously been used for controlled spatial manipulation of live biological specimen in real-time. These biological experiments were carried out over a time-span of several hours while an operator intermittently optimized the optical system. Here we present GPC-based optical micromanipulation in a microfluidic system whe...
We have previously generated neutralization-resistant variants of Tacaribe virus in the presence of a monoclonal antibody (MAb) specific for the envelope glycoprotein. The envelope glycoprotein precursor (GPC) genes of two variant viruses were sequenced following polymerase chain reaction amplification of a specific region of the Tacaribe virus S RNA, and compared with the GPC gene of the paren...
Choline and the related compounds phosphocholine (PC) and glycerophosphocholine (GPC) are considered to be important metabolites in oncology. Past studies have demonstrated correlations linking the relative ratios and concentrations of these metabolites with the development and progression of cancer. Currently, in vivo and tissue ex vivo magnetic resonance spectroscopy methods have mostly cente...
In this paper, we propose a novel classification algorithm, called geometrical probability covering (GPC) algorithm, to improve classification ability. On the basis of geometrical properties of data, the proposed algorithm first forms extended prototypes through computing means of any two prototypes in the same class. Then Gaussian kernel is employed for covering the geometrical structure of da...
Glypican-3 (GPC3), a member of heparan sulfate proteoglycans, attaches to the cell membrane and is frequently observed to be elevated in hepatocellular carcinoma (HCC). However, GPC3 is not detected in normal liver tissues and benign liver lesions. Consequently, GPC3 is currently being used as a diagnostic biomarker and HCC-specific positron emission computed tomography probe to identify HCCs i...
Background Many of the positive adaptations resulting from resistance exercise training (i.e., increased muscle mass and strength, decreased fat mass) are thought to be mediated, in part, by exercise-induced increases in growth hormone (GH). One ingredient that has shown clinical promise in elevating GH is the acetylcholine precursor alpha-glycerylphosphorylcholine (A-GPC). The purpose of this ...
Aplicação de Técnicas de Controle Preditivo em Robô Paralelo Este trabalho apresenta a aplicação de técnicas de controle preditivo para rastreamento de trajetórias de um robô paralelo. A estratégia de controle preditivo generalizado (GPC), que considera o modelo dinâmico linearizado, é usada para melhorar a precisão de rastreamento das trajetórias. O controlador preditivo generalizado é robusti...
