Physical Exercise-Induced Activation of NRF2 and BDNF as a Promising Strategy for Ferroptosis Regulation in Parkinson’s Disease
No full text\ua9 The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024. Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra. Ferroptosis, an iron-dependent form of regulated cell death, may contribute to the progression of PD owing to an unbalanced brain redox status. Physical exercise is a complementary therapy that can modulate ferroptosis in PD by regulating the redox system through the activation of nuclear factor (erythroid-derived 2)-like 2 (NRF2) and brain-derived neurotrophic factor (BDNF) signaling. However, the precise effects of physical exercise on ferroptosis in PD remain unclear. In this review, we explored how physical exercise influences NRF2 and BDNF signaling and affects ferroptosis in PD. We further investigated relevant publications over the past two decades by searching the PubMed, Web of Science, and Google Scholar databases using keywords related to physical exercise, PD, ferroptosis, and neurotrophic factor antioxidant signaling. This review provides insights into current research gaps and demonstrates the necessity for future research to elucidate the specific mechanisms by which exercise regulates ferroptosis in PD, including the assessment of different exercise protocols and their long-term effects. Ultimately, exploring these aspects may lead to the development of improved exercise interventions for the better management of patients with PD
Visible-light-induced photodegradation of gas phase acetonitrile using aerosol-made transition metal (V, Cr, Fe, Co, Mn, Mo, Ni, Cu, Y, Ce, and Zr) doped TiO2
No full textA series of semiconductor photocatalysts based on transition metals (M'=V, Cr, Fe, Co, Mn, Mo, Ni, Cu, Y, Ce, and Zr) incorporated TiO2 (Ti-M'=20 atomic ratio) materials have been synthesized by adopting a one-step liquid flame aerosol synthesis technique. The resulting materials were explored for the destruction of acetonitrile in gas phase under visible light irradiation at ambient conditions. Our H2-TPR studies revealed the formation of MeOTi bonds, which suggest the strong interaction of dopant metal-TiO2 in all the as-synthesized materials. The reduction peaks in Cr-doped TiO2 shifted to much lower temperatures, due to the increase in the reduction potential of titania and chromium. The strong interaction (formation of CrOTi bonds) is the main reason that the Cr-TiO2 is an active photocatalyst in visible light. Our XPS studies suggest that the relative atomic percentage value of Ti3+-Ti4+ characterized by XPS was significantly high for our flame-made Cr-TiO2 nanoparticles (Ti3+-Ti4+=0.89, 32.9percent), whereas, other samples demonstrated poor atomic percentage value of Ti3+-Ti4+ (Ti3+-Ti4+=0.08-0.32). The existence of Ti3+ species with narrow band gap is highly beneficial for the promotion of visible light-induced photocatalytic activity. The position of the Cr 2p peaks shifted to lower binding energies in Cr-doped TiO2 nanoparticles. The electrons migrate from the TiO2 nanoparticles to chromium species, which reveals a strong interaction between Cr and TiO2 nanostructure in the interface of flame-made nanoparticles. Conversely, Mn3+ species combined with TiO2 because its surface metal dispersion was kept high after TiO2 loading. However, Mn3+ incorporated catalyst was inactive because of the small energy driving force for electrons to detrap from Mn2+. The UV-vis spectroscopy results of M'-doped TiO2 (M'=Fe, Cr, V, Co, Ce, and Ni) materials showed augmentation of light absorption in the visible range. The Cr, V and Fe (Ti:M' atomic ratio=20:1) titania aerosol catalysts reduced the bandgap energy of TiO2 to 2.9eV under visible light irradiation. Among all of the catalysts we tested, the transition metals (M'=Cr, Fe, and V) incorporated materials have shown an impressive catalytic performance in visible light. Among all the catalyst tested, Cr-doped titania demonstrated a superior catalytic performance and the rate constant is about 8-19 times higher than the rest of the metal doped catalysts. Their catalytic performances are correlated with the UV-vis spectrum of each synthesized catalyst to reveal the specific role played by each metal ion. © 2013.Anpo M, 2003, J CATAL, V216, P505, DOI 10.1016-S0021-9517(02)00104-5; Asahi R, 2001, SCIENCE, V293, P269, DOI 10.1126-science.1061051; Awate S, 2005, J MOL CATAL A-CHEM, V226, P149, DOI 10.1016-j.molcata.2004.09.055; Boccuzzi F, 1997, J CATAL, V165, P129, DOI 10.1006-jcat.1997.1475; BYRD GD, 1990, J CHROMATOGR, V503, P359, DOI 10.1016-S0021-9673(01)81515-6; Chen HW, 2007, CHEM ENG TECHNOL, V30, P1242, DOI 10.1002-ceat.200700196; Chien H.H., 2012, MICRO NANO LETT, V10, P1033; Choy KL, 2003, PROG MATER SCI, V48, P57, DOI 10.1016-S0079-6425(01)00009-3; Davydov L, 2001, J CATAL, V203, P157, DOI 10.1006-jcat.2001.3334; Elias VR, 2011, TOP CATAL, V54, P277, DOI 10.1007-s11244-011-9658-1; FOX MA, 1993, CHEM REV, V93, P341, DOI 10.1021-cr00017a016; FUJISHIMA A, 1972, NATURE, V238, P37, DOI 10.1038-238037a0; Gaspar AB, 2005, APPL SURF SCI, V252, P939, DOI 10.1016-j.apsusc.2005.01.031; HOFFMANN MR, 1995, CHEM REV, V95, P69, DOI 10.1021-cr00033a004; Hurum DC, 2003, J PHYS CHEM B, V107, P4545, DOI 10.1021-jp0273934; Jenkins R., 1996, INTRO XRAY POWDER DI; Jongsomjit B, 2004, CATAL LETT, V94, P209, DOI 10.1023-B:CATL.0000020548.07021.ec; Klosek S, 2001, J PHYS CHEM B, V105, P2815, DOI 10.1021-jp004295e; Li JX, 2009, J PHYS CHEM C, V113, P8343, DOI 10.1021-jp8114012; Liu Y, 2010, APPL SURF SCI, V256, P3559, DOI 10.1016-j.apsusc.2009.12.154; Madler L., 2004, KONA, V22, P107; Madler L, 2002, J AEROSOL SCI, V33, P369, DOI 10.1016-S0021-8502(01)00159-8; Marques FC, 2008, CATAL TODAY, V133, P594, DOI 10.1016-j.cattod.2007.11.047; MATTHEWS RW, 1990, WATER RES, V24, P653, DOI 10.1016-0043-1354(90)90199-G; Nahar S, 2006, CHEMOSPHERE, V65, P1976, DOI 10.1016-j.chemosphere.2006.07.002; Napoli F, 2009, CHEM PHYS LETT, V477, P135, DOI 10.1016-j.cplett.2009.06.050; Ollis D.F., 1993, ACS S SERIES, V518; Peral J, 1997, J CHEM TECHNOL BIOT, V70, P117, DOI 10.1002-(SICI)1097-4660(199710)70:2117::AID-JCTB7463.0.CO;2-F; Pratsinis SE, 1998, PROG ENERG COMBUST, V24, P197, DOI 10.1016-S0360-1285(97)00028-2; Rahman A., 1995, CATALYSIS PETROLEUM, P419; Reddy EP, 2004, J PHYS CHEM B, V108, P17198, DOI 10.1021-jp047419m; Sanjeev J., 1997, AEROSOL SCI TECHNOLO, V27, P575; Sasaki T, 2006, J PHOTOCH PHOTOBIO A, V182, P335, DOI 10.1016-j.jphotochem.2006.05.031; Sreekanth PM, 2008, CATAL LETT, V122, P37, DOI 10.1007-s10562-007-9365-5; Stark W.J., 2003, US Patent, Patent No. [US20030602305, 20030602305]; Stark W.J., 2006, US Patent, Patent No. [US2006229197, 2006229197]; Stark WJ, 2003, CHEM COMMUN, P588, DOI 10.1039-b211831a; Stark WJ, 2001, J CATAL, V197, P182, DOI 10.1006-jcat.2000.3073; Strobel R, 2006, ADV POWDER TECHNOL, V17, P457, DOI 10.1163-156855206778440525; Su CY, 2012, CRYSTENGCOMM, V14, P3989, DOI 10.1039-c2ce25161b; Sun B, 2005, APPL CATAL B-ENVIRON, V57, P139, DOI 10.1016-j.apcatb.2004.10.016; Teoh WY, 2005, CHEM ENG SCI, V60, P5852, DOI 10.1016-j.ces.2005.05.037; Thirupathi B, 2012, J CATAL, V288, P74, DOI 10.1016-j.jcat.2012.01.003; Thirupathi B, 2011, CATAL LETT, V141, P1399, DOI 10.1007-s10562-011-0678-z; Tong TZ, 2008, J HAZARD MATER, V155, P572, DOI 10.1016-j.jhazmat.2007.11.106; Vollath D, 1997, J EUR CERAM SOC, V17, P1317, DOI 10.1016-S0955-2219(96)00224-5; Wang BQ, 2009, MATER CHEM PHYS, V113, P103, DOI 10.1016-j.matchemphys.2008.07.031; XU YM, 1995, J PHYS CHEM-US, V99, P11501, DOI 10.1021-j100029a031; YAO HC, 1984, J CATAL, V86, P254, DOI 10.1016-0021-9517(84)90371-3; Yu JC, 2006, CHEM COMMUN, P2717, DOI 10.1039-b603456j; Zhu JF, 2006, J PHOTOCH PHOTOBIO A, V180, P196, DOI 10.1016-j.jphotochem.2005.10.017; Zhu ZD, 2000, J PHYS CHEM B, V104, P4690, DOI 10.1021-jp994335i; Zhu ZD, 1999, J PHYS CHEM B, V103, P2680, DOI 10.1021-jp984771p11141
