        Purpose: The present study aimed to compare the immune-enhancing potential of gold nanoparticles (AuNPs) to Alum against rabies vaccine and the related immunological, physiological, and histopathological effects. Materials and Methods: Alum and AuNPs sole and in combination with rabies vaccine were used at 0.35 mg/mL and 40 nM/mL, respectively. Rats used were categorized into six groups (20/each): control rats, rabies vaccine, aluminum phosphate gel, rabies vaccine adsorbed to Alum, AuNPs, and rabies vaccine adjuvant AuNPs. Results: Liver and kidney functions were in the normal range after AuNPs and Alum adjuvanted vaccine compared to control. Interleukin-6 and interferon-γ levels were significantly increased in groups immunized with Alum and AuNPs adjuvanted vaccine, the peak level was in the case of AuNP adjuvanted vaccine on the 14th day. Ninety days post-vaccination, total immunoglobulin G (IgG) against adjuvanted rabies vaccine showed a significantly elevated anti-rabies IgG with AuNPs and Alum adsorbed vaccine compared with unadjuvanted one. The total antioxidant capacity, malondialdehyde (MDA) levels, superoxide dismutase, and glutathione peroxidase activities were significantly increased post-adjuvanted AuNPs adjuvanted vaccine vaccination than in Alum adsorbed vaccine, while MDA was significantly decreased. The histopathological examination revealed detectable alterations post-AuNPs and Alum adjuvanted vaccine immunization compared with liver and kidney profiles post-administration of unadjuvanted and non-immunized groups, meanwhile, splenic tissue revealed hyperplasia of lymphoid follicles indicating increased immune reactivity. Conclusion: The AuNPs are promising enhancers of the immune response as Alum, and the undesirable effects of AuNPs could be managed by using suitable sizes, shapes, and concentrations.

        Optimized Fuzzy Fractional-order Controller for a Nonlinear Chaos System With Period-doubling Bifurcation Analysis

        Eman Moustafa,Belal Abou-Zalam,Abdel-Azem Sobaih,Essam Nabil,Amged Sayed 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.10

        Chaos study and control is one of the dynamic fields of research nowadays. The non-linear dynamic behavior such as fast scale bifurcation results in an unpredictable chaos action so it is essential to eliminate this behavior. So, the main objective of this paper is to propose an optimized fuzzy fractional PID controller to suppress the chaos action and stabilize a nonlinear chaotic. The cuckoo search optimization (CSO) technique’s optimal solution is used to optimize the fractional order controller parameters while considering integral time absolute error as the objective function and the FLC will adapt the controller parameters so that it provides a good performance. Here, the boost converter for permanent magnet DC motor is selected as a chaotic system as case study. The dynamic characteristic of the system is analysed by waveform, phase portrait, and Fillipov theory. Then, the proposed controller is compared with three additional controllers, such as controlling saltation matrix, optimized-PID, and optimizedFractional PID. The proposed technique enhances the performance of the system and stabilized the response of the output and suppress the bifurcation behavior for nonlinear system. Finally, the effectiveness of the proposed technique has justified by simulation results on the PMDC drive system in a specified interval with variation the load to emphasize its superiority over all other controllers.
