Disclosed herein is a composition for gene delivery which forms into liquid crystals in an aqueous fluid including chitosan and a liquid crystal formation material. The composition of the present invention including chitosan and a liquid crystal formation material improves the relatively low binding strength between chitosan and a gene, and also considerably increases the stability of a chitosan nanocomposite in blood serum, thereby performing highly efficient gene delivery and providing excellent stability, thus being useful as a gene therapeutic agent.

Composition for gene delivery comprising chitosan and liquid crystal formation material

Disclosed is a pharmaceutical composition for gene delivery, comprising: (i) a gene; (ii) a water-soluble chitosan; (iii) a thiamine pyrophosphate or a pharmaceutically acceptable salt thereof; (iv) a protamine or a pharmaceutically acceptable salt thereof; and (v) a neutral or anionic phospholipid. The composition can introduce a gene into cells safely and effectively. Composed of non-toxic and injectable components, the composition is safe for the body and can be advantageously commercialized. Notably, it can deliver a gene at high efficiency in vivo as well as in vitro, and is stable in the blood.

Composition for gene delivery

A scheduler and scheduling method that may select a data transmission time interval and a data transmitting station are included in a multi-user Multiple Input Multiple Output (MIMO) communication system. An access point may include a receiver to receive channel measurement signals from stations using a plurality of receive antennas; a channel estimation unit to generate channel state matrices with respect to wireless channels formed from the stations to the receive antennas using the channel measurement signals; and a scheduler to select at least one transmitting station from the stations by considering the channel state matrices and a number of the receive antennas. The receiver may receive a data stream from the selected transmitting stations. Stations receive identifiers corresponding to transmitting stations and/or transmitting antennas to identify stations or antennas for transmitting data streams to the access point.

Scheduler and scheduling method for transmitting data in MIMO based wireless LAN system

A multiple access digital communication method in ultra-wideband (UWB) radio access network is provided. More specifically, a multiple access technique in UWB communication channels is provided where UWB communication channels can be more efficiently used and collisions between multiple access user nodes can be more effectively avoided when the channels have a great multiple path fading. The digital communication method for use in an uplink in a UWB communication system includes the steps of: receiving data symbols from respective nodes, in which the data symbols are transmitted according to respective orthogonal time hopping patterns; checking whether there is a collision of the orthogonal time hopping patterns; and decoding the data symbols depending on whether data symbols of nodes involved in the collision of the orthogonal time hopping patterns are the same.

Multiple access digital communicating method in ultra-wideband radio access networks

A mobile terminal is provided that includes: a display unit configured to display a webpage having a plurality of sections; a wireless communication unit configured to provide Internet access; a memory unit configured to store history information regarding usage of the webpage; and a control unit configured to control a display of a preferred section of the plurality of sections of the webpage upon an access of the webpage such that the preferred section is visually distinguishable from other sections of the plurality of sections, wherein display of the preferred section is based on the stored history information.
