摘要:
The present invention encompasses an apparatus and method for supporting multiple wireless data communication networks between a wireless communications device and a fixed communications device or another wireless communications device. Two network elements compose the physical apparatus, a protocol converter and a router. Upon receiving packet data from a fixed communications device, a router will locate a destination wireless communications device. The router will then convert the packet data to a format usable by the wireless data network that the wireless communications device is currently using for wireless access. After conversion, the router will perform actual transmission of the packet data to the correct destination wireless network. Once the converted packet data is received by the wireless network base station, it will be transmitted via RF to the destination wireless communications device. The router will also perform reverse functions of receiving packet data from a wireless communications device across wireless data network and then perform necessary conversion to a format usable by fixed communications device. The router will then perform actual transmission of the converted packet data to the fixed communications device.
摘要:
The invention provides methods for treating pancreatic dysfunction, particularly diabetes, in mammals using ErbB receptor ligands, such as heregulin, betacellulin, and EGF. Methods of treating such conditions using anti-ErbB receptor agonist antibodies are further provided. The methods of the invention may be performed by direct administration of such therapeutically useful agents to mammals, or alternatively, by exposing certain pancreatic cell types to such agents in vitro and subsequently transplanting the treated cells to a mammal.
