摘要:
The invention discloses injectable hydrogels which are in the form of crosslinked nano beads or particle in the size range 5 nm to 10 μm, comprising PAMAM dendrimer with asymmetrical peripheral end groups such that one of the terminal groups is involved in formation of hydrogel and the other in involved in the conjugation of drugs or imaging agents and their methods of preparation. The said gel is formed by reaction of the PAMAM dendrimer with asymmetrical end groups with other polymer wherein the other polymer is selected from the group of linear, branched, hyperbranched or star shaped polymers with functionalized terminal groups. The PAMAM dendrimer with asymmetrical terminal groups consists of a Generation 2 and above PAMAM dendrimer with symmetrical end groups modified using the amino acids or their modified forms. The gel disclosed in the present invention is formed as small crosslinked particles in the size range 25 nm to 10 μm and is suitable for injectable delivery of hydrogel to any of the body orifices, tissues by intramuscular or subcutaneous route and ocular delivery for the purpose of therapeutic treatment and imaging.

Systems, methods and computer program products for controlling access to electronic content on a client device are provided. Whether access to electronic content is allowed or blocked is based on information and processes performed at the client device. Controlling access to electronic content on a client device can involve locally determining whether access to the electronic content will be allowed, blocked, or will depend upon further analysis performed by a remote device, such as a server. If a webpage is requested, for example, a client device may compare the URL address of the requested webpage, along with keywords and phrases found on the webpage, to locally-stored updateable lists of banned URL addresses and banned keywords and phrases to determining whether access to the electronic content will be allowed, blocked, or will depend upon further analysis.

Systems, methods and computer program products are provided for assigning content category scores to nodes of a linked database. The nodes of the linked database include linking nodes and linked nodes. Each linking node is assigned a linking node score for each content category. The linking node score for each content category represents a degree of relevancy of the linking node to the content category. Each of the linked nodes is linked to by at least one of the linking nodes. Each linked node is assigned a content category score for each content category. The content category score for each content category is based on the linking node score for said content category of each linking node that links to the linked node.

摘要:
A nanodevice composition including N-acetyl cysteine linked to a dendrimer, such as a PAMAM dendrimer or a multiarm PEG polymer, is provided. Also provided is a nanodevice for targeted delivery of a compound to a location in need of treatment. The nanodevice includes a PAMAM dendrimer or multiarm PEG polymer, linked to the compound via a disulfide bond. There is provided a nanodevice composition for localizing and delivering therapeutically active agents, the nanodevice includes a PAMAM dendrimer or multiarm PEG polymer and at least one therapeutically active agent attached to the PAMAM dendrimer or multiarm PEG polymer. A method of site-specific delivery of a therapeutically active agent, by attaching a therapeutically active agent to a PAMAM dendrimer or multiarm PEG polymer using a disulfide bond, administering the PAMAM dendrimer or multiarm PEG polymer to a patient in need of treatment, localizing the dendrimer or multiarm PEG polymer to a site in need of treatment, and releasing the therapeutically active agent at the site in need of treatment.
