摘要:
The present invention resides in the discovery that Smad3, a key downstream mediator of TGF-² signaling, plays a critical role in development and progression of cancer. Thus, this application provides for a novel method of treating cancer by inhibiting Smad3 signaling, such as through administration of SIS3, an inhibitor of Smad3. Further provided are compositions and kits useful for treating cancer by way of inhibiting Smad3 signaling.
摘要:
A frequency of somatic mutations in a biological sample (e.g., plasma or serum) of a subject undergoing screening or monitoring for cancer, can be compared with that in the constitutional DNA of the same subject. A parameter can derived from these frequencies and used to determine a classification of a level of cancer. False positives can be filtered out by requiring any variant locus to have at least a specified number of variant sequence reads (tags), thereby providing a more accurate parameter. The relative frequencies for different variant loci can be analyzed to determine a level of heterogeneity of tumors in a patient.

Methods, apparatuses, and system are provided for analyzing a maternal sample to determine whether a male fetus of a pregnant female has inherited an X-linked mutation from the mother. A percentage of fetal DNA in the sample is obtained, and cutoff values for the two possibilities (fetus inherits mutant or normal allele) are determined. A proportion of mutant alleles relative to a normal allele on the X-chromosome can then be compared to the cutoff values to make a classification of which allele is inherited. Alternatively, a number of alleles from a target region on the X-chromosome can be compared to a number of alleles from a reference region on the X-chromosome to identify a deletion or amplification. The fetal DNA percentage can be computed by counting reactions with a fetal-specific allele, and correcting the number to account for a statistical distribution among the reactions.

摘要:
A protein isolated from the Chinese yam Dioscorea opposita that stimulates estrogen and progesterone release in vitro and in vivo but does not stimulate the proliferation of breast and ovarian cancer cells is disclosed. The protein exhibits anti-osteoporotic activity in vivo. Also provided are the procedure for isolation and purification of the protein and the N-terminal amino acid sequence of the protein.
摘要:
A method for retarding the progression of myopia in a human eye is provided. The method comprises providing (41) a concentric annular multi-zone refractive lens including: at least one correcting zone of optical power for correcting (42) refractive error, and at least one defocusing zone for projecting (43) at least one non-homogenous defocused image in front of at least a part of retina to inhibit myopic eye growth. The at least one defocusing zone has at least one less negative power. The correcting and defocusing zones are alternated (45) in the lens and the zones are connected (46) to each other through integrated progressive transition curves. A system for retarding the progression of myopia in a human eye is also provided.
摘要:
A method for data encoding and associated decoding is based on the concept of batches that allows transmission of a large data file from a source node to multiple destination nodes through communication networks that may employ network coding wherein sparse matrix codes are employed in a network setting. A batch is a set of packets generated by a subset of the input packets using sparse matrix encoder. A sparse matrix encoder can be called repeatedly to generate multiple batches. The batches are generally independent of one another. During the transmission in a communication network, network coding can be applied to packets belonging to the same batch to improve the multicast throughput. A decoder recovers all or at least a fixed fraction of the input packets using received batches. The input packets can be pre-coded using a pre-code before applying sparse matrix codes. The data file can then be reconstructed by further decoding the pre-code.
