Abstract: A head-mountable EEG electrode-containing device is provided based on radially adjustable electrodes to fit the wearer's unique head size and shape. The head-mountable device with an electrode array positioned therein includes multiple head-mountable device sections that are interconnected by mechanical fasteners to facilitate sizing and positioning of the head-mountable device. An array of resilient sleeves is positioned within each head-mountable device section. Each resilient sleeve houses an individual electrode and is deformable for self-orienting. The deformation of the sleeve is such that a central axis passing through the individual electrode housed within the resilient sleeve is maintained in a position approximately normal to a plane tangential to a scalp portion positioned beneath that electrode.

Abstract: A bioprobe based on surface-modified single-phase BaGdF5:Yb/Er upconversion nanoparticles (UCNPs) for multi-modal bioimaging of fluorescent, magnetic resonance imaging (MRI) and computed X-ray tomography (CT) is disclosed herein. The modified UCNPs of the present invention are synthesized by a facile one-pot hydrothermal method with simultaneous surface modification of the nanoparticles. The surface-modified UCNPs of the present invention are useful in a variety of biomedical application fields due to their advantages in in vitro and in vivo multi-modal bioimaging such as small particle size up to 15 nm, substantially free of autofluorescence, low cytotoxicity, capable of being excited at near-infrared (NIR) wavelength, ability to deep cell penetration, long-lasting signal and long circulation time in vivo, different X-ray absorption coefficients at different photon energy levels between Ba and Gd, large magnetic moment, etc.
Abstract: This invention discloses methods, apparatus and systems for assessing an extent of green shipping activities practised by a shipping company. The invention is based on enquiring the shipping company with questions in the dimensions of Company Policy and Procedure, of Shipping Documentation, of Shipping Equipment, of Shipping Cooperation, of Shipping Materials, and of Shipping Design Compliance. These six dimensions constitute six dimensions empirically validated to be essential for assessing the extent of green shipping activities. After the shipping company gives the answers, the answers to questions of each dimension are processed to yield an intermediate result. The resultant six intermediate results are then processed to evaluate the extent of green shipping activities, in order that all the six dimensions are considered in assessing the extent of green shipping activities.

Abstract: A set of biomarkers indicative of early gastric cancer and method of diagnosing gastric cancer at an early stage by directing the these biomarkers in a blood sample. Detection of over-expression of one or more protein biomarks in the group consisting albumin, T-kininogen I, ?-2-HS glycoprotein, ?-1-antitrypsin, afamin and ?-actin and/or detection of under-expression of one or more protein biomarks in the group consisting stress 70 protein, apolipoprotein A-I, apolipoprotein A-IV, transthyretin and murinoglobulin is indicative of the presence of gastric cancer.
Abstract: Multidrug resistance (MDR) is a major problem in cancer chemotherapy. The best characterized resistance mechanism is the one mediated by the over-expression of drug efflux transporters, permeability-glycoprotein (P-gp), which pump a variety of anticancer drugs out of the cells, resulting in lowered intracellular drug accumulation. A series of flavonoid dimers are developed in this invention, which are linked together by linker groups of various lengths. These flavonoid dimers are found to be efficient P-gp modulators that increase cytotoxicity of anticancer drugs in vitro and dramatically enhance their intracellular drug accumulation. It is found that the flavonoid dimers of this invention is also useful in reducing drug resistance in treating parasitic diseases.
