Divalent and trivalent gas-phase coordination complexes of californium: evaluating the stability of Cf(ii).

Dalton transactions (Cambridge, England : 2003)

Dau PD, Shuh DK, Sturzbecher-Hoehne M, Abergel RJ, Gibson JK.
PMID: 27424652
Dalton Trans. 2016 Aug 02;45(31):12338-45. doi: 10.1039/c6dt02414a.

The divalent oxidation state is increasingly stable relative to the trivalent state for the later actinide elements, with californium the first actinide to exhibit divalent chemistry under moderate conditions. Although there is evidence for divalent Cf in solution and...

Dopamine induces cell death, lipid peroxidation and DNA base damage in a catecholaminergic cell line derived from the central nervous system.

Neurotoxicity research

Masserano JM, Baker I, Venable D, Gong L, Zullo SJ, Merril CR, Wyatt RJ.
PMID: 12835100
Neurotox Res. 2000 Feb;1(3):171-9. doi: 10.1007/BF03033288.

Dopamine can be autoxidized to superoxides and quinones. Superoxides can form hydroxyl radicals that are highly reactive with lipids, proteins and DNA leading to neuronal damage and cell death. We used a clonal catecholaminergic cell line (CATH.a) derived from...

Influence of pH, Oxygen, and Humic Substances on Ability of Sunlight To Damage Fecal Coliforms in Waste Stabilization Pond Water.

Applied and environmental microbiology

Curtis TP, Mara DD, Silva SA.
PMID: 16348698
Appl Environ Microbiol. 1992 Apr;58(4):1335-43. doi: 10.1128/aem.58.4.1335-1343.1992.

Simple beaker experiments established that light damages fecal coliforms in waste stabilization ponds by an oxygen-mediated exogenous photosensitization. Wavelengths of up to 700 nm were able to damage bacteria. The ability of wavelengths of >425 nm to damage fecal...

STUDIES ON OXIDATION AND REDUCTION BY PNEUMOCOCCUS : IV. OXIDATION OF HEMOTOXIN IN STERILE EXTRACTS OF PNEUMOCOCCUS.

In the present work on oxidation and reduction by sterile extracts of pneumococcus, the preparations employed contain among other constituents, a hemolytic substance the properties of which have been described by Cole (1, 2) in his studies on pneumococcus...

A novel Drosophila SOD2 mutant demonstrates a role for mitochondrial ROS in neurodevelopment and disease.

Brain and behavior

Celotto AM, Liu Z, Vandemark AP, Palladino MJ.
PMID: 22950046
Brain Behav. 2012 Jul;2(4):424-34. doi: 10.1002/brb3.73. Epub 2012 Jun 25.

Reactive oxygen species (ROS) play essential roles in cell signaling, survival, and homeostasis. Aberrant ROS lead to disease and contribute to the aging process. Numerous enzymes and vigilant antioxidant pathways are required to regulate ROS for normal cellular health....

A mechanistic study of the electrochemical oxygen reduction on the model semiconductor n-Ge(100) by ATR-IR and DFT.

Physical chemistry chemical physics : PCCP

Nayak S, Biedermann PU, Stratmann M, Erbe A.
PMID: 23361398
Phys Chem Chem Phys. 2013 Apr 28;15(16):5771-81. doi: 10.1039/c2cp43909c. Epub 2013 Jan 29.

The electrochemical oxygen reduction reaction (ORR) on a n-Ge(100) surface in 0.1 M HClO4 was investigated in situ and operando using a combination of attenuated total reflection infrared (ATR-IR) spectroscopy and density functional (DFT) calculations. The vibrational modes of...

Development of a simultaneous multiple measurement method for superoxide generation from phagocytes using the cytochrome c reduction method.

Environmental health and preventive medicine

PMID: 21432427
Environ Health Prev Med. 1996 Jul;1(2):80-6. doi: 10.1007/BF02931195.

It is important to measure superoxide generation in biological samples in research concerning reactive oxygen, because most reactive oxygen species biologically generated are derived from superoxides.This paper reports the establishment of a simultaneous multiple measurement method for detection of...
