Clioquinol rescues Parkinsonism and dementia phenotypes of the tau knockout mouse

open access: yesNeurobiology of Disease, 2015
Iron accumulation and tau protein deposition are pathological features of Alzheimer's (AD) and Parkinson's diseases (PD). Soluble tau protein is lower in affected regions of these diseases, and we previously reported that tau knockout mice display motor ...

Oxidative stress: oxidants and antioxidants [PDF]

open access: yesExperimental Physiology, 1997
An imbalance between oxidants and antioxidants in favour of the oxidants, potentially leading to damage, is termed ‘oxidative stress’. Oxidants are formed as a normal product of aerobic metabolism but can be produced at elevated rates under pathophysiological conditions. Antioxidant defense involves several strategies, both enzymatic and non‐enzymatic.

Effect of Water Chemistry on Zeta Potential of Air Bubbles

open access: yesInternational Journal of Electrochemical Science, 2013
Effects of various factors on zeta potential of air bubbles in aqueous solution were studied. It was found that the water pH, surfactants types and concentration, and water temperature had significant roles on the zeta potential of air bubbles.

Oxidative Shielding or Oxidative Stress? [PDF]

open access: yesThe Journal of Pharmacology and Experimental Therapeutics, 2012
In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage.

FK506-Binding Protein 2 Participates in Proinsulin Folding

open access: yesBiomolecules, 2023
Apart from chaperoning, disulfide bond formation, and downstream processing, the molecular sequence of proinsulin folding is not completely understood. Proinsulin requires proline isomerization for correct folding.

Iodine-catalyzed diazo activation to access radical reactivity

open access: yesNature Communications, 2018
Radical reactivity of diazo compounds, useful organic building blocks, is yet underexplored. Here, the authors report an iodine-catalyzed radical activation of diazo compounds affording a variety of substituted cyclopropanes, pyrroles and epoxides under ...
