5Turning up the NAD^(+)-mitophagy axis to treat Alzheimer's disease显示文摘The increase in the prevalence of individuals with Alzheimer's disease(AD)combined with the lack of a cure calls for the development of novel therapies against AD(Canter et al.,2016).The key disease-defining pathological features of AD are the accumulation of extracellular amyloid-beta(Aβ)plaques(accompanied by increasing intracellular Aβ_(1-42))and higher intracellular neu rofi brilla ry tangles,comprised mostly of hyperphosphorylated tau protein/pTau(Goedert,2015;Hardy,2017).It is evident that the elderly are more predisposed to develop AD,and thus aging is considered to be the primary risk factor for AD.By extra polation,strategies that delay aging may also slow down(if not stop)AD.Evandro F.Fang Alexander Anisimov 2023Neural Regeneration Research2023,18,2:0
6Phase fragility and mechatronic reliability for Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3) ferroelectric single crystals-A review显示文摘Single crystals of(1x) Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3)(PMN-xPT)near their morphotropic phase boundaries(MPBs)are under extensive investigations for their extraordinary high dielectric and piezoelectric behavior.Applications of those single crystals facilitated the breakthrough in ultrasonic transducer materials and devices.Ferroelectric materials are known to be fragile which often leads to various reliability failures in applications involving electric loadings.In a mechanical sense,the failure modes concern the fracture under an intensive electric field,and the fatigue crack propagation under an alternating electric field.In an electrical sense,the failure is exhibited by degenerated hysteresis loop by shrinking the remnant polarization and expanding the coercive field.All these modes degrade the performance for ferroelectric devices.As a departure from the tetragonal TÞferroelectric materials,exemplified by BaTiO_(3) and Pb(ZrTi)O_(3),the domain structures of PMN-PT around the MPB are versatile and intricate,depending sensitively on the composition variation,orientation and previous loading history.In this review,the attention is mainly focused on three aspects.First,the phase fragility and multiphase coexistence are presented for both[100]-and[101]-oriented PMN-PT single crystals.Second,investigations on electric field-induced fatigue crack propagation are described,along with the orientation effect on the crack propagation behavior.Third,the inverse effects of the phase transition and fatigue crack growth on the polarization behavior,or the interaction between the mechanical and electrical degradations will be elucidated.The review aims for better understanding the underlying mechanism for the ultrahigh performance of the PMN-PT single crystals,to bridge the studies of ferroelectric materials from the mechanical and electrical senses,as well as to evaluate the reliability of PMN-PT single crystals under device applications.F.Fang W.Yang 2014Journal of Advanced Dielectrics2014,4,1:0
