Impact of tillage, cover crop, and in situ bioreactors on nutrient loss from an artificially drained Midwestern Mollisol.

Nutrient losses via subsurface tile cause environmental degradation of aquatic ecosystems. Various management practices are primarily aimed at reduction of nitrate leaching in tile discharge; however, studies on leaching of other nutrients are limited. A replicated plot experiment was initiated in 2016 as part of the Long-Term Agroecosystem Research (LTAR) network Croplands Common Experiment to quantify the effectiveness of management practices on leaching of NO-N, total P, K, and S from drained soils.

How do patients determine when their inhaler is empty? Insights from an analysis of returned inhalers and a patient survey.

Background: Inhalers are widely used for the management of asthma and chronic obstructive pulmonary disease. However, there is little knowledge about the extent to which an inhaler is used and when it is disposed of, despite the implications for an individual's health (when used beyond the recommended number of doses (overused)), and medicine wastage, healthcare costs and the environment (when discarded with remaining doses (underused)). To explore inhaler use, we assessed the number of doses remaining in pressurised metered-dose inhalers (pMDIs) returned via a Chiesi Inhaler Recycling scheme.

The LTAR Cropland Common Experiment at Upper Mississippi River Basin-Ames.

Agricultural systems evolve from the interactions of climate, crops, soils, management practices (e.g., tillage, cover crops, nutrient management), and economic risks and rewards.

Hard X-ray inverse Compton scattering at photon energy of 87.5 keV.

Production of hard X-ray via inverse Compton scattering at photon energies below 100 keV range aimed at potential applications in medicine and material research is reported. Experiments have been performed at the Brookhaven National Laboratory, Accelerator Test Facility, employing the counter collision of a 70 MeV, 0.3 nC electron beam with a near infra-red Nd: YAG laser (1064 nm wavelength) pulse containing ~ 100 mJ in a single shot basis.

Clinicoepidemiological Profile of Ciguatera Cardiotoxicity: A Systematic Review.

Patients with ciguatera poisoning commonly present with gastrointestinal and neurologic symptoms, but its cardiotoxicity has been largely unrecognized. This systematic review is the first to summarize the evidence regarding clinical characteristics of cardiotoxicity from ciguatera poisoning to provide the illness script and pertinent knowledge for clinicians. Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including "ciguatera" and "cardiotoxicity" from their inception to January 2024.
