This invention is directed to a process for irreversibly binding nucleic acid to solid phase and corresponding processes for the utilization thereof. Nucleic acid is bound to solid phase matrixes exhibiting sufficient hydrophilicity and electropositivity to irreversibly bind the nucleic acids from a sample. These processes include nucleic acid (double or single stranded DNA and RNA) capture from high volume:low concentration specimens, buffer changes, washes, and volume reductions, and enable the interface of solid phase bound nucleic acid with enzyme, hybridization or amplification strategies. The invention, solid phase irreversibly bound nucleic acid, may be used, for example, in repeated analyses to confirm results or test additional genes in both research and commercial applications. Further, a method is described for virus extraction, purification, and solid phase amplification from large volume plasma specimens.

The invention relates to chimeric molecules comprising a virus coat sequence and a receptor sequence that can interact with each other to form a complex that is capable of binding a co-receptor. Such chimeric molecules therefore exhibit functional properties characteristic of a receptor-coat protein complex and are useful as agents that inhibit virus infection of cells due to occupancy of co-receptor present on the cell, for example. In particular aspects, the chimeric polypeptide includes an immunodeficiency virus envelope polypeptide, such as that of HIV, SIV, FIV, FeLV, FPV and herpes virus. Receptor sequences suitable for use in a chimeric polypeptide include, for example, CCR5 and CXCR4 sequences.

Security check method and apparatus reduces problmes that can arise if the user security data set becomes known by unauthorized persons. To address this problem only part of the user data set is recorded in insecure sections of the system. For example, a security check preventing unauthorized remote access to a shared computer is provided by capturing a user data set representing a user's iris, operating the user's personal computer to select only a portion of the captured data set requested by the shared computer and transmitting the portion along a telecommunications line. The shared computer derives partial data sets from stored user data sets using a similar selection to that used by personal computer and compares the partial data set it has derived with the partial data set transmitted by the personal computer in deciding whether to grant access. Point-of-sale devices and cards recording only partial user data sets are also disclosed.

A system and method for managing access to a satellite-based transponder by a plurality of aircraft each having a mobile radio frequency (RF) system. The system employs a ground-based, central control system for managing access to the satellite-based transponder so that the aggregate power spectral density (PSD) of the RF signals of all the mobile systems does not exceed, at any time, limits established by regulatory agencies to prevent interference between satellite systems. This is accomplished by a dual control loop arrangement for monitoring the signal-to-noise ratio (Eb / No) of the RF signal transmitted by the satellite-based transponder. A ground-based control loop is used whereby a ground-based central controller monitors the Eb / No and transmits commands to the aircraft (via the satellite transponder) to maintain the Eb / No of the transmitted signal within a predetermined range. A fast scan angle compensation is used by the mobile system of the aircraft to implement another control loop to further adjust the transmit power. This control loop maintains the Eb / No of the signal transmitted to the satellite-based transponder at the commanded level inbetween updates from the ground-based central controller.
