This work investigated the role of structure in the binding of polysaccharides from 10 regionally different strains of Lentinula edodes to Toll-like receptor 4 (TLR-4) on monocytes (THP-1) and the potential effect of this interaction on tumor cell viability. Principal component analysis and multiple linear regression identified arabinose, glucose 1 -> 4 linkage, and molecular weights about 2700 and 534 kDa as the significant determinant factors associated with TLR-4 binding activity. The branched alpha-(1,4)-glucan (L10) had the strongest ability to bind to TLR-4 and induce THP-1 cell differentiation. L10 induction of the THP-1 cell differentiation, superoxide production, and cytokine production followed the TLR-4/MyD88/IKK/NF kappa B pathway. Coculture of irradiated human lung adenocarcinoma A549 cells with L10-activated THP-1 cells resulted in significantly decreased percentage of viable A549 cells from 66 to 37% (p = 0.018), increased levels of superoxide, interleukin-8, and RANTES, and decreased levels of angiogenin and vascular endothelial growth factor. The results indicate that L10-activated monocytes have the potential to boost the antitumor immune response and antitumor activity of radiotherapy.
Nitrogen Plasma-Assisted Codoped P-type (In, N):SnO(2) Ultra-Fine Thin Films and N-ZnO/p-In:SnO(2) Core-Shell Heterojunction Diodes Fabricated by an Ultrasonic Spray Pyrolysis Method

In this study, tin oxide (SnO(2)) solution mixtures containing indium (In) of 0%, 3%, 7%, 15%, and 30% were used to fabricate In- and N-codoped SnO(2) films on glass at 400 degrees C using an ultrasonic spray pyrolysis method combined with thermal annealing at 600 degrees C and post nitrogen plasma treatment. X-ray diffraction analysis demonstrated that the incorporation of elemental In in the SnO(2) film primarily induces the evolution of crystalline phases from In-doped SnO(2) to Sn-doped In(2)O(3), depending on the doping concentration. Upon exposure to N plasma, the dark current dramatically increases in proportion to the treatment duration (5-40 min); the dark current can be enhanced for the 3% and 7%-doped samples by as much as 3 orders of magnitude compared to the untreated samples. Hall measurements confirmed that hole carriers could dominate the SnO(2) host matrix to promote p-type properties at a low In content (3% and 7%) with an increase in resistance compared to undoped samples. However, samples with higher In content (15% and 30%) showed the opposite trend, due to the formation of a secondary phase of n-type In(2)O(3). X-ray photoelectron spectroscopy was used to probe the incorporation and dissociation of chemical bonds between the doped In and N atoms in the SnO(2). Moreover, depth profile measurements showed a correlation between the elemental compositions and elemental distributions of the codoped SnO(2) film. Current-voltage (I-V) characterization revealed the improved behavior of heterojunction diodes consisting of a p-type (In, N)-doped SnO(2) thin film deposited on n-type ZnO nanorod arrays.

The present invention discloses a dynamic calibration method for a single and multiple video capture devices. The present invention can acquire the variations of the pan angle and tilt angle of a single video capture device according to the displacement of the feature points between successive images. For a plurality of video capture devices, the present invention includes the epipolar-plane constraint between a plurality of video capture devices to achieve the goal of dynamical calibration. The calibration method in the present invention does not require specific calibration patterns or complicated correspondence of feature points, and can be applied to surveillance systems with wide-range coverage.

A context-based adaptive binary arithmetic coding (CABAC) decoding device and a coding method thereof are provided. The device comprises: a context memory address calculator, calculating an address identifying a memory location in a context model memory for storage of a context model in next cycle; a mixed context memory, in which the context model of the context memory address calculator is stored and from which the context model is read; a two-bin context adaptive binary arithmetic decoder, outputting several parameters for updating the range and offset of the context model, based on the context model of the mixed context memory and deciding several bins; and a binary syntax element comparator, judging whether a current binary sequence corresponds to the value of syntax elements, based on the bins so as to select a correct memory address.
Self-assembly of an antireflective moth-like structure using antibody-functionalized nanowires and nanopore arrays

A novel framework to fabricate moth-like nanopillar arrays was proposed. In this scheme, nanowires were first cross-linked with anti-gold nanoparticle (GNP) antibodies and mixed with the nanopore array pre-deposited by GNP, which was then followed by centrifugation. An optimal success rate of 95% was finally obtained by choosing nanorods with an aspect ratio of 5:1 by modifying with 10 ng mL(-1) antibodies, and by inserting them into a pore array pre-deposited with 54.4 mu M GNP. The nanopillar arrays thus fabricated showed high levels of antireflective efficiency across a broad wavelength. Here we demonstrate the assembly of nanowires and nanopores into nanopillar arrays by the assistance of antibody-antigen binding. The application of bio-nano-interaction provides an economic, time-saving, and throughput approach to manipulating objects on the nanoscale.
