Abstract:
The present invention provides a method for changing nitrogen utilization efficiency in a plant comprises regulating the expression of Arabidopsis NRT 1.7 or an orthologue thereof so that the nitrate remobilization from older leaves to young leaves in the plant is regulated, thereby the nitrogen utilization efficiency is changed. The present invention also provides a transgenic plant obtainable by transforming a plant with an expression construct with a high or low level of expression of NRT 1.7. On the other hand, the present invention yet provides a chimera nitrate transporter, a DNA molecule coding for this chimera transporter and an expression vector thereof.
Abstract:
A method for fabricating a semiconductor layer comprising: a) growing a semiconductor layer on a foreign substrate; b) forming at least one opening on the semiconductor layer, wherein the opening exposes the interface between the semiconductor layer and the foreign substrate; and c) removing at least part of the semiconductor solid state material along the interface between the semiconductor layer and the foreign substrate. The removing step c) is preferably achieved by selective interfacial chemical etching. The semiconductor layer may be utilized as a substrate for fabrication of a wide variety of electronic and opto-electronic devices and integrated circuitry products.
Abstract:
Disclosed are extracts, compositions, and methods for treating cancer and inflammatory disorders. Also disclosed are methods for preparing extracts or compounds for treating the disorders.
Abstract:
An organic dye used in a dye-sensitized solar cell is described, having general formula (1): wherein Ar1 represents a substituted or unsubstituted arylene group, Ar2 and Ar3 each independently represent a substituted or unsubstituted aryl group, Sp1 represent a single bond or a spacer group allowing conjugation between Ar1 and the furan moiety, Sp2 represent a single bond or a spacer group allowing conjugation between the furan moiety and Ac, Ac represents an acceptor group, and Y represents an anchoring group.
Abstract:
Some general aspects of the invention relate to approaches for generating a graphical representation of players' gaming experience. Gaming information representing player activity is first collected. The gaming information includes, for example, data obtained from a game log file characterizing a set of game events, and a set of images (e.g., comicshots associated with the game events) for use in generating the graphical representation. Images are associated with significance scores determined from at least the collected gaming information. Based on the significance scores, a set of images is selected for use in the graphical representation, and partitioned into subsets of images each subset to be presented in a respective one of one or more successive presentation units of the graphical representation. In some examples, the graphical representation can be enhanced by introducing textual annotations and/or sound effects to the images.
Abstract:
Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.
Abstract:
A mutated severe acute respiratory syndrome-associated coronavirus 3C-like protease and use thereof for cleaving a protein that includes a cleavage site recognizable by the mutated protease to yield a polypeptide fragment of interest.
Abstract:
Methods for determining the quality of a biomolecular microarray to determine suitability of the microarray for performing specific binding reactions, such as hybridization, are provided. Methods are based on staining a microarray with a solution of detectable nanoparticles that reversibly stain the biomolecules through an electrostatic interaction to select microarrays that meet quality standards for hybridization reactions. A gold nanoparticle solution based staining method for DNA microarrays is provided. Destaining methods allowing multiple rounds of hybridization of nanogold stained microarrays are provided. Microarrays selected by methods of the invention are provided.
