Considerations for measurement of individual nanoparticles or microparticles by ICP-MS: determination of the number of particles and the analyte mass in each particle
John W. Olesik,Patrick J. Gray +1 more
TL;DR: In this article, the unique considerations to determine the number of particles per liter and analyte mass distributions from single particle ICP-MS measurements with quadrupole or sequential sector field mass spectrometers are discussed.

Cooking rice in excess water reduces both arsenic and enriched vitamins in the cooked grain
TL;DR: Rinsing rice before cooking has a minimal effect on the arsenic (As) content of the cooked grain, but washes enriched iron, folate, thiamin and niacin from polished and parboiled rice, while cooking rice in excess water efficiently reduces the amount of As.
Crossover between anti- and pro-oxidant activities of different manganese oxide nanoparticles and their biological implications.
TL;DR: ESR spectroscopy was used to evaluate the catalytic activities of three MnOx NPs towards biologically relevant antioxidants and reactive oxygen species and found that all three NPs possess both pro- and anti-oxidant activities, including oxidase-, catalase-, and superoxide dismutase (SOD)-like activities but without peroxidase-like or hydroxyl radical scavenging activity.

Cernich,Bruce Kaup,Dennis Hoover,Anthony A. Gaspari,Juan Liu,Erin Harberts,Lawrence Brown,Jose A. Centeno,Patrick J. Gray,Hanna Xu,Katherine Squibb +19 more
TL;DR: Renal biomarkers showed minimal DU-related effects on proximal tubule function and cytotoxicity, but significant biomarker results were observed when urine concentrations of multiple metals also found in fragments were examined together.

Surveillance for long-term health effects associated with depleted uranium exposure and retained embedded fragments in US veterans.
Katherine S. Squibb,Joanna M. Gaitens,Susan M. Engelhardt,Jose A. Centeno,Hanna Xu,Patrick J. Gray,Melissa A. McDiarmid +6 more
TL;DR: Urine biomonitoring and health surveillance programs were developed to gather information about health risks associated with chemicals released from embedded fragments and will help to develop guidelines for surgical removal of tissue-embedded fragments.
