Neuroprotective Effects of MIP-15 Peptide from Morchella importuna Against Ischemic-Hypoxic Brain Damage in Rats

引用

Food Science and Human Wellness 2024年

作者： Chuan xiong ping Li Qiang Luo Chia Wei Phan Xin Jin Wenli Huang Biotechnology and Nuclear Technology Research Institute， Sichuan Academy of Agricultural Sciences The Second Affiliated Hospital， Chongqing Medical University Department of Anatomy， Faculty of Medicine， Universiti Malaya

Hypoxic-ischemic encephalopathy (HIE) is a prominent cause of neuronal damage and neonatal death， and effective treatment strategies remain limited. In a prior investigation， we purified a novel peptide (designated MIP-15) from the rare mushroom Morchella importuna， demonstrating its notable free radical scavenging activity. Nevertheless， the potential neuroprotective role of MIP-15 in neonatal hypoxic-ischemic brain damage (HIBD) and its underlying mechanism remain elusive. The purpose of this study was to evaluate whether MIP-15 exerts neuroprotective effects by inhibiting the mitochondrial apoptotic pathway after HIBD. A HIBD model in 7-day-old (P7) rats was established by the Rice–Vannucci method to evaluate the effect of MIP-15 on the neurological damage severity and space cognitive ability of rats. Subsequently， an oxygen glucose deprivation/reoxygenation (OGD/R) model was established in rat primary hippocampal neurons to explore the mechanism of MIP-15 action. Both in vivo and in vitro data showed that MIP-15 markedly restored endogenous antioxidative activity， decreased brain water content， and ameliorated pathological abnormalities following HIBD. The spatial cognitive ability and motor function of HIBD rats were also repaired. Moreover， in primary hippocampal neurons after OGD/R， MIP-15 increased cell viability by inhibiting the mitochondrial-dependent apoptosis pathway， as manifested by stabilization of the mitochondrial membrane potential， prevention of the release of cytochrome c， upregulation of Bcl-2/Bax， and reduction in the triggering of caspase proteins. These data indicate that MIP-15 may have the potential to act as a neuroprotective agent.

Lithium(Li) metal has been considered one of the most promising anodes due to its high theoretical capacity, lightweight and low electrochemical potential. The cell-level energy density of rechargeable lithium metal batteries(LMBs) is expected to surpass 500 Wh kg^(-1) after replacing the graphite anode in lithium-ion batteries [1].

Online interactive identification method based on ESO disturbance estimation for motion model of double propeller propulsion unmanned surface vehicle

Control Theory and Technology 2024年第2期22卷 292-314页

In this paper, the online parameter identification problem of the mathematical model of an unmanned surface vehicle (USV) considering the characteristics of the actuator is studied. A data-driven mathematical model of motion is very meaningful to realize trajectory prediction and adaptive motion control of the USV. An interactive identification algorithm (ESO–MILS, extended state observer–multi-innovation least squares) based on ESO is proposed. The robustness of online identification is improved by expanding the state observer to estimate the current disturbance without making artificial assumptions. Specifically, the three-degree-of-freedom dynamic equation of the double propeller propulsion USV is constructed. A linear model for online identification is derived by parameterization. Based on the least square criterion function, it is proved that the interactive identification method with disturbance estimation can improve the identification accuracy from the perspective of mathematical expectation. The extended state observer is designed to estimate the unknown disturbance in the model. The online interactive update improves the disturbance immunity of the identification algorithm. Finally, the effectiveness of the interactive identification algorithm is verified by simulation experiment and real ship experiment.
