Amplified singlet oxygen generation in metallated-porphyrin doped conjugated polymer nanoparticles [PDF]
, 2018 We report on the mechanism and efficiencies of singlet oxygen O2(1Δg) generation of nanoparticles (NP) of the conjugated polymer (CP) poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) doped with platinum octaethylporphyrin (PtOEP) suspended in water.

Lactate: The Ultimate Cerebral Oxidative Energy Substrate? [PDF]
Journal of Cerebral Blood Flow & Metabolism, 2006 Research over the past two decades has renewed the interest in lactate, no longer as a useless end product of anaerobic glycolysis in brain (and other tissues), but as an oxidative substrate for energy metabolism. While this topic would be considered blasphemy only three decades ago, much recent evidence indicates that lactate does play a major role ...

Molecular Oncology, EarlyView.Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Human HDL subclasses modulate energy metabolism in skeletal muscle cells
Journal of Lipid ResearchIn addition to its antiatherogenic role, HDL reportedly modulates energy metabolism at the whole-body level. HDL functionality is associated with its structure and composition, and functional activities can differ between HDL subclasses.

Ultrasonic treatment with nickel electroplating combined with oxidation for developing γ-Al2O3 washcoat on Fe-Cr-Al substrate [PDF]
, 2012 Fe-Cr-Al is used as metallic support for catalytic converter due to its high thermal conductivity, lower heat capacity, high temperature and mechanical shock resistance. γ-Al2O3 is the most widely used material as washcoat which embedded on metallic

Mechanisms of cytochrome P450 substrate oxidation: MiniReview [PDF]
Journal of Biochemical and Molecular Toxicology, 2007 AbstractCytochrome P450 (P450) enzymes catalyze a variety of oxidation and some reduction reactions, collectively involving thousands of substrates. A general chemical mechanism can be used to rationalize most of the oxidations and involves a perfenyl intermediate (FeO3+) and odd‐electron chemistry, i.e.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
