Dietary avocado oil supplementation attenuates the alterations induced by type I diabetes and oxidative stress in electron transfer at the complex II-complex III segment of the electron transport chain in rat kidney mitochondria

Journal of Bioenergetics and Biomembranes, 2013
Impaired complex III activity and reactive oxygen species (ROS) generation in mitochondria have been identified as key events leading to renal damage during diabetes. Due to its high content of oleic acid and antioxidants, we aimed to test whether avocado oil may attenuate the alterations in electron transfer at complex III induced by diabetes by a ...

Orthogonal bis(terpyridine)-Fe(II) metal complex oligomer wires on a tripodal scaffold: rapid electron transport.

Chemical Communications, 2013
The present work reports a tripodal scaffold for bis(terpyridine)-Fe(II) oligomer wires on an Au(111) surface: the tripodal scaffold realised both orthogonality of the oligomer wires, and fast interfacial electron transfer through the oligomer wires.

Inhibition of Photosynthetic Electron Transport by UV-A Radiation Targets the Photosystem II Complex¶

Photochemistry and Photobiology, 2007
We have studied the inhibition of photosynthetic electron transport by UV-A (320-400 nm) radiation in isolated spinach thylakoids. Measurements of Photosystem II (PSII) and Photosystem I activity by Clark-type oxygen electrode demonstrated that electron flow is impaired primarily in PSII.

Electron transport dynamics in thin polymer films containing tris(2,2′-bipyridine)osmium(III/II) complexes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1987
Abstract Rotating carbon disk electrodes were modified by a random copolymer (PSS-PVP) of styrenesulfonate and 4-vinylpyridine. The polymer was spincoated onto the electrodes, crosslinked by reaction with 1,2-dibromoethane, then loaded with Os(bpy)2+3 by ion exchange.

The Effects of Cationic Antiseptics on Spectral Characteristics and Electron Transport in Isolated Photosynthetic Complexes of Photosystems I and II

Biophysics
The effects of cationic antiseptics (used in micromolar concentrations) on active PS II core complexes isolated from spinach plants with an intact water oxidation complex and on PS I core complexes from the cyanobacterium Synechocystis sp. PCC6803 were studied.

STUDIES ON PHOTOACTIVATED ELCTRON-TRANSPORT SYSTEMS. II. ELECTRON-TRANSFER QUENCHING OF PHOTOEXCITED RUTHENIUM(II) COMPLEXES BY VARIOUS BIPYRIDINIUM IONS

Chemistry Letters, 1978
Abstract Rate constants for quenching emission from photoexcited tris-(2,2′-bipyridine)- and tris(1,10-phenanthroline)Ru(II) complexes by bipyridinium ion vary with the redox potential of the quencher. Annihilation of the geminate ion pairs at the quenching step can be reduced by the addition of EDTA.

Antimicrobial Piano Stool and Polypyridyl Ru(II) Complexes with Thiazolhidrazinylidene‐Chroman‐2,4‐Dione: Tautomerism, Membrane Disruption, and Electron Transport Interference

ChemBioChem
A library of (η6‐p‐cymene)Ru(II) and Ru(II) bis‐bpy complexes bearing thiazolhidrazinylidene‐chroman‐2,4‐dione was synthesized, characterized, and the molecules are evaluated for their antibacterial activity and cytotoxicity. From this library, several compounds are identified as being active against Methicillin‐resistant Staphylococcus aureus and ...

Mitochondrial Electron Transport Chain Complex II Dysfunction Causes Premature Aging of Hematopoietic Stem Cells

Stem Cells, 2022
AbstractMitochondria are indispensable in maintaining hematopoietic stem cells (HSCs), and mitochondrial complex II (MCII) has been recognized as a key component of HSCs. However, the physiological role of MCII on long-term hematopoiesis and hematopoietic reconstitution capacity remains unknown.
