Golden Tandem of Photothermal Ablation and Simultaneous Anti-Inflammation in One Nanoparticle for Activated Macrophage-Targeted Atherosclerosis Treatment by Lu Y, Wang Y, Li Y, Li Y, Jiang YW, Li J

“…The preparation and characterization of GSNPD, their cellular toxicity, photothermal conversion and targeted ablation efficiency, anti-inflammation and ROS scavenging effect, as well as the inhibition of foam cell formation were studied in vitro.Results: The experimental results showed that the fabricated GSNPD NPs displayed positive effects on anti-atherosclerosis by pro-inflammatory macrophages ablation, NO production and ROS scavenging.Discussion: GSNPD NPs were designed to effectively and accurately ablate pro-inflammatory macrophages by recognizing and targeting to SR-A overexpressed on the activated macrophages of arterial plaques via PTT, and simultaneous inhibit the PTT-induced inflammation through the laser-activated NO release in situ. …”

Efficient and safe software defined network topology discovery protocol by Dong LI, Junqing YU, Yongpu GU, Pengcheng ZHAO

“…The network topology discovery in OpenFlow-based software-defined networks is mainly achieved by utilizing the OpenFlow discovery protocol (OFDP).However, it has been observed in existing research that OFDP exhibits low updating efficiency and is susceptible to network topology pollution attacks.To address the efficiency and safety concerns of the network topology discovery protocol, an in-depth investigation was conducted on the mechanism and safety of OFDP network topology discovery.The characteristics of network topology establishment and updating in OFDP were analyzed, and an improved protocol named Im-OFDP (improved OpenFlow discovery protocol) based on the minimum vertex covering problem in graph theory was proposed.In Im-OFDP, the switch port table and network link table were initially established using prior information obtained from OFDP network topology discovery.Subsequently, a graph model of the network topology was constructed, and the minimum vertex covering algorithm in graph theory was employed to select specific switches for the reception and forwarding of topology discovery link layer discovery protocol (LLDP) packets.Multi-level flow tables were designed based on the network topology structure, and these flow entries were installed on the selected switches by the controller to process LLDP packets.To address security issues, dynamic check code verification in LLDP packets was employed to ensure the safety of network links.Additionally, a network equipment information maintenance mechanism was established based on known network topologies to ensure the safety of the network equipment.Experimental results demonstrate a significant reduction in the number of network topology discovery messages, bandwidth overhead, and CPU overhead through the deployment of Im-OFDP.Moreover, the response time for node failures and link recovery time after mode failure is substantially reduced.Im-OFDP also effectively mitigates various network topology pollution attacks, such as link fabrication and switch forgery attacks.Overall, Im-OFDP has the capability to enhance the efficiency and safety of SDN topology discovery.…”
