A Mechanistic Dissection of Multifaceted Complement Attack in Age-Related Macular Degeneration Reveals the Superiority of C3 Inhibition. [PDF]

open access: yesAdv Sci (Weinh)
Complement‐mediated RPE degeneration extends beyond terminal MAC injury. A four‐hit mechanism emerges in which C3a and C5a disrupt mitochondrial function, while C3b and MAC compromise the phagolysosomal system. Upstream C3 inhibition suppresses this full spectrum of pathogenic effectors, providing broader cellular protection than C5 blockade.

CR-MAC: Cooperative Relaying MAC Protocol for VANETs

open access: yes2019 Scientific Meeting on Electrical-Electronics & Biomedical Engineering and Computer Science (EBBT), 2019
In this paper, a novel cooperative relaying medium access control (CR-MAC) protocol is proposed for vehicular ad hoc networks (VANETs). Three data transmission modes have been offered to increase the throughput which are direct transmission (DT), cooperative relaying (CR) and multi-hop relaying (MHR).
