摘要:
This present disclosure relates to folate mimetics and their use in therapeutic and diagnostic applications. More particularly, the disclosure relates to using des-glutamyl folic acid analogs recognized by and selectively bound by folate receptors and other folate binding proteins and the use of such analogs for targeted delivery of diagnostic or therapeutic agents to folate-receptor bearing cell populations.
摘要:
A cell population expressing folate receptors is selectively targeted with a non-peptide folic acid analogue. The non-peptide folic acid analogue is conjugated to a diagnostic or therapeutic agent to enable selective delivery of the agent to the targeted cell population.

An invention is disclosed for automatically formatting removable media. A default media image is generated in computer memory in response to detecting unformatted media in a computer drive. The media image includes default file system structures for the media. In response to receiving a request to read the media, data is returned based on the default file system structures. However, the removable media is automatically prepared for content in response to receiving a request to write information to the media, wherein the default media image in memory is committed to the media.

A method of implementing a multicast routing protocol in routers is provided to manage the assignment of multicast transport addresses and to forward data from a single transmitting endpoint to multiple receiving endpoints. This method in conjunction with a method for implementing the multicast routing protocol as a transport protocol layer service for endpoints provides an internet wide multicast transport service. The multicast transport service provides the capability of transmitting data from a single source to multiple receivers on interconnected networks efficiently and without having to send duplicate copies of the data on any single network. Routers and endpoints transmit and receive multicast packets in a manner which is independent of the network layer datagram protocols used by the multicast transport service. Multicast control packets are exchanged using a multicast transaction protocol which allows routers and endpoints to execute transactions in a manner that does not require either routers to know the state of specific endpoints or endpoints to know the state of specific routers.
摘要:
A multicast network system comprises a data network which provides a medium for data transfer. A media source having a control packet and media packets coupled to the data network broadcasts the control packet and the media packets to the data network and rebroadcasts the control packet in conjunction with the media packets to the data network. A media receiver is coupled to the network and receives the control packet and the media packets from the data network to process the control packet and the media packets to produce a media output.

A software-driven method for the initialization of re-writable optical media is provided. Embodiments include a software-driven method for the formatting of re-writable optical media to include defining a file system and writing a UDF reader to the optical media to enable implementation on a plurality of optical media devices in a plurality of operating system environments. The re-writable optical media is initialized using either user data or initialization patterns in a background operation to allow user interaction with the optical media during initialization. Methods are provided for multi-track capabilities of the optical media. Prior to initialization of the entire media space of an optical media, a session can be closed to enable compatibility of a partially initialized media in a ROM device. Further methods are provided to re-open a closed session to complete initialization of the media space.

Radiopharmaceuticals for imaging myocardial tissues are prepared by forming lipophilic, cationic complexes of radioactive metal ions with metal chelating ligands comprising the Schiff base adducts of triamines and tetraamines with optionally substituted salicylaldehydes. The lipophilic, cationic, radioactive complexes of the invention exhibit high uptake and retention in myocardial tissues. Preferred gallium-68(III) complexes in accordance with this invention can be used to image the heart using positron emission tomography.
