Abstract: L'invention concerne une deuxième génération de traitements par antinéoplastons présentant une activité antinéoplasique nettement améliorée. La famille des antinéoplastons comporte notamment les substances suivantes: phénylacétate (PN), 3-phénylacétyl-amino-2,6,pipéridinedione (CN), et dérivés par hydrolyse de CN: phénylacétylglutamine (PG) et iso-phénylacétylglutamine (Iso-PG). L'augmentation de l'activité antinéoplasique résulte en partie de l'amélioration notable de l'acheminement des composés antinéoplastons dans les cellules. Fait important et inattendu, cette augmentation s'explique aussi par la capacité du médicament administré sous cette forme à orienter la circulation intracellulaire des antinéoplastons pour amener ceux-ci sur les sites de liaison intracellulaires ayant une influence sur la viabilité et la prolifération des cellules. Les présentations liposomales des composés antinéoplastons augmentent in vitro l'activité antinéoplasique d'un facteur 750 à 1500 par rapport à l'administration de ces composés autrement que sous forme liposomale. De plus, la présentation liposomale renforce l'absorption cellulaire des composés antinéoplastons d'un facteur 30 à 80 et plus. Il s'est avéré que la présentation liposomale augmente également l'apport intracellulaire d'antinéoplaston CN (3-phénylacétyl-amino-2,6,pipéridinedione) en amenant la CN sur les sites de liaison intracellulaires ayant une influence sur la viabilité et la prolifération des cellules et bloquant leur hydrolyse. Dans des conditions ou la CN à l'état libre ne présente aucune activité antinéoplasique, la CN sous forme liposomale peut provoquer un blocage sensiblement total et de relativement longue durée de la croissance cellulaire. On constate que la croissance cellulaire redémarre lorsque le taux intracellulaire de CN non liée descend en-dessous du seuil de détectabilité.

Title: Method and system for reading intelligent utility meters
Inventor: BRUNN BRIAN T
IPC: G08C17/00
Filed: 1999-03-03
Granted: 2003-10-21
Abstract: A meter reading system preferably includes an external modem module (EMM), a hub and a data collection system. The EMM communicates with one or more utility meters and, as such, is preferably selected on the basis that it incorporates a communication format that is compatible with the communication format of the utility meter such that the utility meter does not require modification to be communicatively coupled to the EMM. The EMM obtains meter data from the utility meter and converts to a radio frequency communication format. The radio frequency formatted data is then transferred to the hub. The hub then translates the radio frequency data into an analog or digital telephone communication format, which is then transferred to the data collection system for use by the utility as desired, e.g. utility billing, tracking, control, etc. The data collection system need only recognize one communication format rather than attempting to accommodate numerous message formats such as wires, coaxial cable, optical fiber, or radio frequency.

Title: Packet-transmitting system
Inventor: WATANABE EIICHI
IPC: H04N21/435
Filed: 2000-09-18
Granted: 2005-04-05
Abstract: A packet-transmitting system comprising a transmitter and a receiver. In the transmitter, the packet-allocating circuit receives a stream of packets. The circuit allocates the packets having PIDs a1 to b1 to the transmission channel #1, the packets having PIDs a2 to b2 to the transmission channel #2, and so forth. The circuit allocates the packets having PIDs a N to b N to the last transmission channel #N. The control-data generating circuit time-divides and multiplexes packet- group data (groups of PIDs) representing the groups of packets to be transmitted via the channels #1 to #N, thereby generating control data to be transmitted through the transmission channel #0. The packets in the channels #0 to #N are multiplexed by a CDM system. In the receiver, the groups of packets, transmitted via the channels #1 to "N, are recognized from the control data transmitted via the channel #0, and only the signals transmitted via the channel designated by a user are extracted and reproduced. Thus, the receiver can therefore receive only the packet the user desires.
