Abstract: A system and a method for direct communication between a remote ground transceiver and the intended recipient, such as a management station, through a satellite. The disclosed system and method are particularly useful for the rapid transmission of short messages, such as alarm messages, from equipment at remote sites to the management station. Optionally and preferably, messages can also be passed from the management station to the remote site, for example in order to transmit a command, such that a human supervisor at the management station would be able to respond to the alarm message. The messages are rapidly transmitted by passing directly from the satellite to the final recipient The satellite optionally determines the information necessary for billing and optionally passes this information to a ground center for sending the bill to the client.

Abstract: A method of transplanting a transplant derived from a donor into a recipient is disclosed. The method comprises the steps of (a) transplanting the transplant into the recipient; and (b) administering to the recipient a dose including non-alloreactive anti-third party cytotoxic T-lymphocytes (CTLs), wherein the non-alloreactive anti-third party CTLs are generated by directing T-lymphocytes of the donor against a third party antigen or antigens, the dose is substantially depleted of T-lymphocytes capable of developing into alloreactive CTLs, thereby preventing or ameliorating both graft rejection by the recipient and graft versus host disease.
