Abstract:
Use of an ubiquitination pathway-related factor, its agonist or antagonist in the preparation of a composition for regulating FOXP3, IL-2, and/or IFN-γ activity, in which the ubiquitination pathway-related factor is selected from: Toll-like receptor, ubiquitin ligase, pro-inflammatory cytokine family receptor, and/or its coding sequence. The new type of regulatory factors can regulate regulatory T cells and immune system by regulating FOXP3, IL-2, and/or IFN-γ activity. The regulatory factors and their derivatives can also be used as immunoadjuvant for treating or preventing major diseases (such as, infectious diseases and tumor, etc).

The first and second conductive layers are disposed on the first and second substrates respectively. The second insulation layer and the first insulation layer are disposed on the second conductive layer in order. The first electrode layer is disposed between the liquid crystal layer and the second insulation layer and is electrically isolated from the second conductive layer. The second electrode layer is disposed between the liquid crystal layer and the second insulation layer and is electrically isolated from the second conductive layer.
Abstract:
Acquisition of magnetic resonance (MR) data in a predetermined three-dimensional volume segment of an examination subject with an MR apparatus proceeds by the volume segment being excited with an RF excitation pulse, and repeated, temporally sequential implementation of the following in order to respectively read out an echo train: Switch a refocusing pulse. Switch a first phase coding gradient in a first direction and a second phase coding gradient in a second direction. Switch an additional magnetic field gradient for spatial coding in a third direction which is perpendicular to the first direction and the second direction, wherein the MR data of a k-space line are read out while the additional magnetic field gradient is switched. Every k-space line corresponds to a line of k-space that corresponds to the volume segment. At least one k-space line is read out repeatedly in a middle segment of k-space.
Abstract:
An integral forming method for a composite metal includes: a preparation step including preparing powders of at least two metals or alloys; a formation step including producing a single blank from the powders of one of the at least two metals or alloys by pressing molding or metal injection molding, and then producing a composite metal blank from the single blank and the powders of a remainder of the at least two metals or alloys; and a sintering step including sintering the composite metal blank into a composite metal product. The processing procedures are simplified, and the production is easier. Limitation to the choices of materials is small. The bonding strength of the composite metal is enhanced.
Abstract:
A support for an electronic device includes a mounting apparatus and a supporting apparatus. The mounting apparatus includes a fixing bracket mounted to the main body of an electronic device, an engaging member slidably mounted to the fixing bracket, and a resilient member connected between the fixing bracket and the engaging member. The supporting apparatus includes a connecting bracket detachably mounted to the fixing bracket. When the engaging member is slid relative to the fixing bracket, a stop piece moves away from the connecting hole, and a hook extends through the connecting hole. After the engaging member is released the stop piece moves to the connecting hole to engage with the hook.
Abstract:
The disclosure discloses a realizing method and system for taking a mobile terminal as a wireless Universal Serial Bus (USB) flash disk. A client sends a Server Message Block (SMB) protocol data packet as an access request to a mobile terminal in a Bluetooth way after establishing a Logical Link Control and Adaptation Protocol (L2CAP) link with the mobile terminal; the mobile terminal executes the received SMB data packet and sends the SMB data packet as the access result to the client in a Bluetooth way; and the client displays the received access result. The method, device and system for realizing the wireless USB flash disk can take a mobile terminal as a wireless USB flash disk without any additional cable by combining the SMB protocol with the Bluetooth technology and using the mutual conversion between the SMB data packet and the L2CAP data packet, thereby being convenient to users.
Abstract:
The disclosure provides a downlink transmission method and an eNodeB in a multiple input multiple output system. The method includes: obtaining channel quality indication of a User Equipment (UE) to generate a channel condition indication value; obtaining channel rank indication of the UE to generate a channel correlation indication value; obtaining uplink channel impulse response estimation data of the UE to generate a channel variation state indication value; selecting a downlink transmission mode according to the channel condition indication value, the channel correlation indication value and the channel variation state indication value; transmitting data to the UE in the selected downlink transmission mode. Because of extracting information from a current channel as a basis of a subsequent selection of the downlink mode, the disclosure can greatly improve a resource utilization ratio of a system and realize a better wireless transmission effect.
