Molybdenum behavior during early diagenesis: Insights from Mo isotopes

Creator:: Poulson Brucker, Rebecca L., McManus, James, Severmann, Silke, and Berelson, William M.
Abstract:: We present molybdenum isotope and concentration data from 14 sites in the eastern Pacific from the central California to the Peru margin. The environments studied have been chosen to represent a broad range in oxidation-reduction (redox) potential, which provide a framework for the behavior of this redox-sensitive element. Manganese-rich hemipelagic...

Oceanic germanium/silicon ratios: Evaluation of the potential overprint of temperature on weathering signals

Creator:: Hammond, Douglas E., McManus, James, and Berelson, William M.
Abstract:: Diatom remains indicate the oceanic Ge/Si ratio (μmol/mol) has varied temporally, ranging from Miocene values of 0.9 to Last Glacial Maximum (LGM) values of 0.55, with the present value of 0.69. These ratios lie between those for the primary sources for these elements: continental weathering (Ge/Si = 0.5) and hydrothermal...

Barium cycling in the North Pacific: Implications for the utility of Ba as a paleoproductivity and paleoalkalinity proxy

Creator:: McManus, James, Berelson, William M., Hammond, Douglas E., and Klinkhammer, Gary P.
Abstract:: Benthic incubation chambers have been deployed in a variety of geochemical environments that provide a comprehensive geochemical framework from which to address issues related to Ba geochemistry and the use of Ba as a paleoproxy. First order budgets for barium show that in the equatorial Pacific, present rates of Ba...

The cost of multiple sclerosis drugs in the US and the pharmaceutical industry: Too big to fail?

Creator:: Hartung, Daniel M., Bourdette, Dennis N., Ahmed, Sharia M., and Whitham, Ruth H.
Abstract:: Objective: To examine the pricing trajectories in the United States of disease-modifying therapies (DMT) for multiple sclerosis (MS) over the last 20 years and assess the influences on rising prices. Methods: We estimated the trend in annual drug costs for 9 DMTs using published drug pricing data from 1993 to...

Contribution of Calcium Oxalate to Soil-Exchangeable Calcium

Creator:: Dauer, Jenny M. and Perakis, Steven S.
Abstract:: Acid deposition and repeated biomass harvest have decreased soil calcium (Ca) availability in many temperate forests worldwide, yet existing methods for assessing available soil Ca do not fully characterize soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it has been hypothesized that the highly insoluble biomineral Ca...

A Review of Contemporary Methods for the Presentation of Scientific Uncertainty

Creator:: Makinson, K. A., Hamby, D. M., and Edwards, J. A.
Abstract:: Graphical methods for displaying uncertainty are often the most concise and informative way to communicate abstract concepts. Presentation methods currently in use for the display and interpretation of scientific uncertainty are reviewed. Numerous subjective and objective uncertainty display methods are presented, including qualitative assessments, node and arrow diagrams, standard statistical...

Evaluation of a Workplace Treadmill Desk Intervention: A Randomized Controlled Trial

Creator:: Schuna, John M., Jr., Swift, Damon L., Hendrick, Chelsea A., Duet, Megan T., Johnson, William D., Martin, Corby K., Church, Timothy S., and Tudor-Locke, Catrine
Abstract:: OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...

Effect of β-Blockers on Cardiac and Pulmonary Events and Death in Older Adults With Cardiovascular Disease and Chronic Obstructive Pulmonary Disease

Creator:: Lee, David S. H., Markwardt, Sheila, McAvay, Gail J., Gross, Cary P., Goeres, Leah M., Han, Ling, Peduzzi, Peter, Lin, Haiqun, Dodson, John A., and Tinetti, Mary E.
Abstract:: CONTEXT: In older adults with multiple conditions, medications may not impart the same benefits seen in patients who are younger, or without multi-morbidity. Furthermore, medications given for one condition may adversely affect other outcomes. Beta-blocker (β-Blocker) use with coexisting cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) is such...

PRex: an experiment to investigate detection of near-field particulate deposition from a simulated underground nuclear weapons test vent

Creator:: Keillor, Martin E., Arrigo, Leah M., Baciak, James E., Chipman, Veraun, Detwiler, Rebecca S., Emer, Dudley F., Kernan, Warnick J., Kirkham, Randy R., MacDougall, Matthew R., Milbrath, Brian D., Rishel, Jeremy P., Seifert, Allen, Seifert, Carolyn E., and Smart, John E.
Abstract:: A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...

The Effect of Intensive versus Usual Blood Pressure Control on Kidney Function Among Persons With Prior Lacunar Stroke: A Post-Hoc Analysis of the Secondary Prevention of Small Subcortical Strokes (SPS3) Randomized Trial

Creator:: Peralta, Carmen A., McClure, Leslie A., Scherzer, Rebecca, Odden, Michelle C., White, Carole L., Shlipak, Michael, Benavente, Oscar, and Pergola, Pablo
Abstract:: Background—The effect of intensive blood pressure (BP) lowering on kidney function among individuals with established cerebrovascular disease and preserved estimated glomerular filtration rate (eGFR) is not established. Methods and Results—Among 2610 participants randomized to a lower (<130 mm Hg) versus higher (130–149 mm Hg) systolic BP target with repeated measures...
