摘要:
The present invention relates compositions and methods for microRNA (miRNA) expression profiling of colorectal cancer. In particular, the invention relates to a diagnostic kit of molecular markers for identifying one or more mammalian target cells exhibiting or having a predisposition to develop colorectal cancer, the kit comprising a plurality of nucleic acid molecules, each nucleic acid molecule encoding a miRNA sequence, wherein one or more of the plurality of nucleic acid molecules are differentially expressed in the target cells and in one or more control cells, and wherein the one or more differentially expressed nucleic acid molecules together represent a nucleic acid expression signature that is indicative for the presence of or the predisposition to develop colorectal cancer. The invention further relates to corresponding methods using such nucleic acid expression signatures for identifying one or more mammalian target cells exhibiting or having a predisposition to develop colorectal cancer as well as for preventing or treating such a condition. Finally, the invention is directed to a pharmaceutical composition for the prevention and/or treatment of colorectal cancer.

X-ray pixel beam array systems and methods for electronically shaping radiation fields and modulating radiation field intensity patterns for radiotherapy are disclosed. One exemplary pre-clinical system may include addressable electron field emitters (102, 104) that are operable to emit a plurality of electron pixel beams (106, 108, 110). Each electron pixel beam may correspond to an x-ray target (124) and x-ray pixel beam collimation aperture (136, 138) to convert a portion of energy associated with the electron pixel beam to a corresponding x-ray pixel beam (140, 142). Further, the x-ray pixel beam array collimator (130) forms a one-to-one correspondence between individual electron pixel beam and its corresponding x-ray pixel beam. One exemplary clinical system may include a high-energy electron source (1203), an n-stage scanning system (1210), x-ray pixel beam targets (1212), and an x-ray pixel beam array collimator (1214). A controller (1206) may sequentially direct electron beam pulses to predetermined x-ray pixel targets and produce an electronically controlled radiation field direction, pattern; and intensity pattern.

An isolated rice non-endosperm tissue expression promoter, OsTSP I, and the use thereof. The promoter comprises the defined sequence of 1785 by (SEQ ID NO: 1), given in the specification, or its fragment or variant, or a nucleotide sequence If which hybridizes to SEQ ID NO: 1, or its fragment or variant, under stringent conditions. The activity of OsTSP I is comfirmed by transgenic methods. As determined histochemically, OsTSP I reglulates GUS expression in a tissue-specific manner and is not active in endosperm tissues. The OsTSP I can be used as a powerful tool for the investigation and control of gene expression in rice and other crops. It is particularly advantageous for development of safe transgenic foods such as rice.

摘要:
Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, and oral cavity surfaces. Peptide-based body surface coloring reagents, preferably tooth coloring reagents, are formed by coupling a tooth binding peptide to a pigment binding peptide, either directly or through a spacer. The peptide-based body coloring reagents may be used in conjunction with pigments to color body surfaces.

Peptides have been identified that bind with high affinity to hair, skin, and nails. Peptide-based hair conditioners, hair colorants, skin conditioners, skin colorants, and nail colorants are described. The peptide-based hair conditioners and hair colorants consist of a hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively. The peptide-based skin conditioners and skin colorants consist of a skin-binding peptide coupled to a skin conditioning agent or a colorant, respectively. The peptide-based nail colorants consist of a nail-binding peptide coupled to a coloring agent. In all these compositions, the peptide may be directly coupled to the active agent or the coupling may be via a spacer. Personal care compositions containing these peptide-based conditioners and colorants are also described.
