    • The present technology provides new compositions comprising at least one cross-linked co-polymer. In some embodiments, the polyacrylamide co-polymer comprises water soluble subunits, cross-linking subunits, and iron chelating subunits. In other embodiments, the co-polymer comprises water soluble units, cross-linking subunits, and substituted subunits, which can be conjugated with iron-chelating agents. When these new particles are exposed to certain environments, such the presence of strong acids or oxidation agents, these particles are capable of breaking up so that the iron chelating agents can chelate iron or other metals from their environments. Methods to prepare these new compositions are also provided. These compositions or compositions comprising nanogels of the present technology may be used to treat metal overload conditions such as iron overload resulting from chronic transfusions.
    • 本技术提供了包含至少一种交联共聚物的新组合物。 在一些实施方案中,聚丙烯酰胺共聚物包含水溶性亚基,交联亚基和铁螯合亚基。 在其它实施方案中,共聚物包含可与铁螯合剂缀合的水溶性单元,交联亚单元和取代亚单元。 当这些新的颗粒暴露于某些环境,如强酸或氧化剂的存在时,这些颗粒能够分解,使得铁螯合剂可以从其环境中螯合铁或其它金属。 还提供了制备这些新组合物的方法。 包含本技术的纳米凝胶的这些组合物或组合物可用于治疗由慢性输血引起的金属过载状况,例如铁超载。

    • The present invention relates to radio communications technologies and discloses a method, an apparatus, and a system for sending a data packet to avoid repeated forwarding of data when a user equipment hands over between an access point and an evolved NodeB. The method includes: receiving, by an evolved NodeB, a data packet sent by a core network and sending the data packet to a current access point; and keeping caching the data packet on the evolved NodeB before determining that a user equipment has correctly received the data packet from the current access point. The present invention is applicable to data transmission in a network.
    • 本发明涉及无线电通信技术,并且公开了一种方法,装置和系统,用于当用户设备在接入点和演进节点B之间切换时,发送数据分组以避免数据重复转发。 该方法包括:由演进的节点B接收由核心网发送的数据分组,并将数据分组发送到当前接入点; 并且在确定用户设备已经从当前接入点正确地接收到数据分组之前,将数据分组保持缓存在演进的节点B上。 本发明适用于网络中的数据传输。
