摘要:
The present invention includes compositions and methods for delivering one or more active agents in vivo by contacting a target organ or tissue with a microbubble encapsulated active agent comprising a neutrally charged lipid microbubble loaded with cationic liposomes comprising one or more active agents and selectively releasing the active agents at the target by exposing the microbubble at the target with ultrasound, wherein the active agents remain protected in the microbubble until selectively release at the target.

Embodiments of the present invention improve information exchange, and in particular, the exchange of data objects between different software systems. In one embodiment, the present invention includes a method of exchanging information comprising analyzing the attributes of the objects. Objects may be stored in a repository and retrieved using attributes. In some applications, objects are received and sent to participants without accessing any information in the objects themselves. Different applications include object warehousing operable across different communication mediums that support different names or name spaces, classes, aliases, groups, geospatial information, or tokens, or combinations thereof.
摘要:
Embodiments of the present invention relate to an automated way for a non-technical person to create or modify software functionality in support of a business process without needing expertise in software. According to the invention, an automated matching tool may apply user input expressed semantically to a database of semantic information associated with syntactic information, to match the user input with a service (e.g., an application program) capable of performing a business process step corresponding to the input.

摘要:
An ultrasound-mediated gene transfer method named Ultrasound Targeted Microbubble Destruction (UTMD) for the delivery of human vascular endothelial growth factor (hVEGF) gene to transplanted islets and the surrounding tissue is described herein. The delivery of hVEGF promotes islet revascularization and survival. The inventors, first transplanted human islets were transplanted into diabetic nude mice liver followed by the induction of non-viral plasmid vectors encoding hVEGF or Green Fluorescent Protein (GFP) gene in the host liver by UTMD. Transplantation without gene delivery was also performed as a control. Blood glucose, serum human insulin, C-peptide levels and the revascularization in graft islets were evaluated. The findings of the method of the present invention indicated that hVEGF gene delivery to host liver using UTMD promoted islet revascularization after islet transplantation and improved the restoration of euglycemia.

The introduction of the human NeuroD1 gene into human non-endocrine pancreatic epithelial cells (NEPECs) for producing insulin producing cells in vitro is described herein. Cytokeratin19 (CK19) positive NEPECs were transfected with plasmids encoding human NeuroD1 gene under human CK19 promoter. On characterization following the induction it was found that NEPEC+ND strongly expressed NeuroD1 and insulin mRNA. The ratio of NeuroD1 and human insulin positive cells in NEPEC+ND was significantly higher than NEPEC. Human insulin and C-peptide levels in culture media in NEPEC+ND were significantly higher than NEPEC. The findings demonstrate that human NeuroD1 under control of the CK19 promoter induces the differentiation of CK19 positive NEPECs into insulin producing cells.

Embodiments of the present invention provide improved event handling between systems. In one embodiment, the present invention includes software event handling method comprising receiving a first event from a first source system in a plurality of source systems, the first event including event information, accessing context information corresponding to the first event, generating a second event based on at least a portion of the event information and context information using one or more rules, assigning a priority to the second event, and sending the second event to a first target system in a plurality of target systems.
摘要:
Communication systems and methods transfer information between a client device and a vendor device through a firewall between the client device and the vendor device by using a communications protocol that will normally allows pass through the firewall and/or by e embedding the information in a file format that will normally pass through the firewall. The information can be transmitted using the hypertext transfer protocol, and/or is embedded in an HTTP document or in an e-mail message. If the client device is on a secure side of the firewall and the vendor device needs to initiate communication with the client device, the vendor device can send an e-mail message to the client device asking the client device to initiate the communication session. Because the client device has initiated the communication, the firewall should allow the response to the client device's request to pass through from the vendor device to the client device.
摘要:
The present invention includes compositions and methods for regenerating glucose-responsive cells by ultrasound-targeted microbubble destruction in the pancreas, wherein the composition comprises a pre-assembled liposome-nucleic acid complex in contact with within and about a microbubble, wherein the pre-assembled liposome-nucleic acid complex comprises a NeuroD gene under the control of the promoter, wherein disruption of the microbubble in the pancreas at a target site delivers the nucleic acid into pancreas cells at the location of the ultrasound disruption, wherein cells that incorporate the nucleic acid express insulin in response to high blood glucose levels.
