摘要:
This invention generally relates to a composition for developing novel anti-cancer drugs and/or vaccines and producing microRNA precursor (pre-miRNA) and/or its shRNA homologs/mimics/derivatives, and a method thereof. The present invention also relates to a use of a composition in producing novel prokaryote-produced microRNA precursor (pro-miRNA) capable of being delivered into human cells and processed by the cells into microRNA-like effectors to elicit specific silencing effects on certain targeted oncogenes, subsequently leading to a therapeutic result of tumor suppression and cancer therapy. Specifically, the method of the present invention includes inducing an expression of the pre-miRNA/pro-miRNAs, particularly human pre-miR-302, in prokaryotes through pol-2 or pol-2-like RNA promoter. Most importantly, the composition of the present invention is further a novel pre-miRNA-based drug that is capable of reprogramming the malignant properties of high-grade human liver cancers into a low-grade benign or even relatively normal stage—a mechanism called “Cancer Reversion”.

This invention generally relates to a composition and its method of use for inducing adult stem cell (ASC) expansion and/or derivation in vitro, using miR-302-like pre-miRNAs, shRNAs and/or siRNAs, all of which contain a shared sequence of 5′-UAAGUGCUUC CAUGUUU-3′ (SEQ ID NO: 7) in the 5′-end, and further in conjunction with the use of some wound-healing-related defined factors, including but not limited to basic fibroblast growth factor (bFGF)/fibroblast growth factor 2 (FGF-2), leukemia inhibitory factor (LIF), insulin-like growth factor (IGF), Epidermal growth factor (EGF), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor (TGF), tumor necrosis factor (TNF), stem cell factor (SCF), homeobox proteins (HOX), Notch, GSK, Wnt/beta-Catenin signals, interleukins, and/or bone morphogenetic proteins (BMPs). The principle of the present invention is related to a novel mechanism of inducible symmetric ASC division recently found in a skin wound healing model in vivo. The resulting amplified ASCs are useful for treating a variety of human aging- and cell dysfunction-associated disorders, including but not limited to Alzheimer's disease, Parkinson's disease, motor neuron disease, stroke, diabetes, osteoporosis, myocardial infraction, hemophilia, anemia, AIDS, leukemia, lymphoma and many kinds of cancers as well as aging.

This invention is related to a novel sugar-like chemical composition and its use for diabetes therapy. Particularly, the present invention teaches the use of monosaccharide-like glycylated sugar alcohol compounds to block or reduce sugar absorption in diabetes patients, so as to prevent the risk of hyperglycemia symptoms. Glycylation of sugar alcohols is a totally novel reaction that has never been reported before. Therefore, the novelty of the present invention is that for the first time glycylated sugar alcohols not only was found but also was found to be useful for treating Diabetes mellitus. In addition, the present invention teaches a method for producing these glycylated sugar alcohols. In sum, the present invention includes not only a kind of novel sugar-like chemical compositions and its use for treating diabetes but also a state-of-the-art protocol and methodology for producing such a novel composition via glycylation of sugars and sugar alcohols.

摘要:
A method and system for communicating includes a plurality of cells having base units therein. Each of the base units communicates with a plurality of users within the cells. A communications platform is located in a stratospheric location for transmitting and receiving information with respect to the base units. A gateway station communicates with the communications platform and routes signals to terrestrial networks or other user back through the communications platform. A microcell within at least one of the cells is used to provide coverage in a small geographic area such as within a building. Each of the microcells is also in communication with the gateway station through the platform.

A communications system and method of operating the communications system includes a high altitude communication device that communicates with a plurality of user terminals and a gateway station. The gateway station couples the users to terrestrial networks and other users. The high altitude communication device has a controller that assigns a first code to a beam of a first plurality of users. When one of the first plurality of users moves to interfere with one of the other of the first plurality of users, the beam associated with the user is reassigned another code.
摘要:
A communication system has a communication infrastructure and a gateway station communicating a communication signal to the communication infrastructure. An airplane having an antenna coupled to a processing circuit for establishing a plurality of multiple communication links corresponding to the communication infrastructure is used. The gateway station generates multiple datagrams from the television signal and transmits the multiple datagrams through the multiple dynamic links. The antenna receives the datagrams from the infrastructure and the processing circuit and reassembles the datagrams into the communication signal.
摘要:
A mobile wireless communications system including a plurality of individual transponding nodes of various types, all in communication with a central processing hub. A local user signal is processed by the central processing hub and radiated through multiple paths to a plurality of the plurality of individual transponding platforms simultaneously. The signal is then re-radiated by each of the plurality of the plurality of individual transponding platforms to a mobile terminal that receives the re-radiated signal from the plurality of the plurality of individual transponding platforms coherently and in phase. The number of transponders and codes used to transmit each user signal can be readily adapted to user requirements.
