The neurotoxicity of Aβ is associated with the formation of free radical by interacting with redox active metals such as Cu(2+). However, the relationship between ion-interaction, ion-driven free radical formation, and Aβ conformation remains to be further elucidated. In the present study, we investigated the correlation of Cu(2+) interaction and(More)
Lysine 5,6-aminomutase (5,6-LAM) and ornithine 4,5-aminomutase (4,5-OAM) are two of the rare enzymes that use assistance of two vitamins as cofactors. These enzymes employ radical generating capability of coenzyme B12 (5'-deoxyadenosylcobalamin, dAdoCbl) and ability of pyridoxal-5'-phosphate (PLP, vitamin B6) to stabilize high-energy intermediates for(More)
— In this paper, we propose a multi-factors cell selection (MFCS) scheme for heterogeneous networks with multimedia traffic. In heterogeneous networks, it is an important issue to determine a suitable access network for call request to support seamless service and high-speed connectivity. The MFCS scheme first chooses candidate cells for call request to(More)
Previously, we have demonstrated that the conformation of Aβ40 can be manipulated using trifluoroethanol (TFE) [18]. Since TFE was extensively used in this study, the effect of TFE on Cu 2+ binding affinity and H 2 O 2 generation has to be evaluated before further studies. Figure S1(B) shows the plot of DCF intensity vs. TFE percentage. It can be seen that(More)
WCDMA/WLAN interworking networks are considered to support high-data-rate multimedia services and high mobility. In this paper, we propose a utility function-based access selection method (UFAS) to determine which cell is most suitable for a mobile node's service request in heterogeneous WCDMA and WLAN networks. The UFAS method contains three parts, cells(More)
— This letter proposes a fast handoff protocol (FHP) for cellular IEEE 802.11e wireless local area network (WLAN) systems. The FHP, which is standard compatible, provides a controlled contention period (CCP) designated for handoff requests (HO-REQs), arranges these HO-REQs to contend sequentially in CCP, and proposes a fuzzy adjustment method (FAM) to(More)
