Screening of the best small interference RNAs. .cndot. Delivery of viral diseases specific small interference RNAs with cationic lipid complexes as spray vaccines during the window period of viral infection.     By imitating viruses' infectious route of entry into an organism, small interference RNAs vaccines could be directly sprayed to the infected respiratory tract during the window period of virus infection. The direct delivery of small interference RNAs into specific cells would save the usage of small interference RNAs and increase the efficiency of silencing of gene expression in the target organs or tissues and also reduce potential toxicity and other side effects. Small interference RNAs vaccines could inhibit the multiplication of influenza virus and FMDV, degrade their specific mRNAs and prevent their epidemics. Small interference RNAs vaccines as window period vaccines would be the most promising and practical vaccines.

Inventor: KEZYS VYTAUTAS ROBERTAS
IPC: H04W74/02
Filed: 2005-03-24
Abstract: In one illustrative technique, a contention-free period indication is communicated by a wireless access point (AP) (e.g. a battery-powered AP) to a plurality of mobile communication devices within a beacon of a superframe. The contention-free period indication identifies a duration of a contention-free period within which the mobile devices must refrain from communicating through the AP. During each contention period subframe of each superframe, information is communicated to and/or from the mobile devices through a wireless transceiver of the AP. During each power conservation subframe of each superframe, the wireless transceiver is placed into a power conservation mode which is at least part of the contention-free period. Alternatively, or in combination with the wireless transceiver being placed in the power conservation mode, information for the mobile devices may be communicated to and/or from another AP within each relay subframe of each superframe which is at least part of the contention-free period. Advantageously, power consumption may be reduced in the AP and/or a single radio interface may be utilized in the AP for communications. The durations of the power conservation subframe and the other subframes may be variably adjusted to tradeoff power savings with a real-time capacity requirement of the AP.
