The LTAR Cropland Common Experiment at Lower Chesapeake Bay.

The Lower Chesapeake Bay (LCB) Long-Term Agroecosystem Research (LTAR) Common Experiment (CE) located in Beltsville, MD, focuses on research of concern to producers of the major regional crops, which are corn (Zea mays L.), soybean [Glycine max (L.) Merr.

Management of Acute Lung Injuries and Acute Respiratory Distress Syndrome in the Tactical and Prolonged Field Care Setting.

The authors examine two acute lung injuries (ALI) that can occur in the tactical setting - positive pressure pulmonary edema and inhalation injury - as well as acute respiratory distress syndrome (ARDS), all of which can quickly progress in a prolonged field care (PFC) environment. These conditions present complex problems to emergency department (ED) and intensive care unit (ICU) teams worldwide, requiring intimate knowledge of their distinct disease pathophysiology and advanced critical care equipment. These challenges are compounded in the world of the Special Operations Forces (SOF) medic who often operates as the sole provider in environments with both limited resources and prolonged evacuation times.

Triclosan disrupts immune cell function by depressing Ca influx following acidification of the cytoplasm.

Triclosan (TCS) is an antimicrobial agent that was effectively banned by the FDA from hand soaps in 2016, hospital soaps in 2017, and hand sanitizers in 2019; however, TCS can still be found in a few products. At consumer-relevant, non-cytotoxic doses, TCS inhibits the functions of both mitochondria and mast cells, a ubiquitous cell type. Via the store-operated Ca entry mechanism utilized by many immune cells, mast cells undergo antigen-stimulated Ca influx into the cytosol, for proper function.

A Novel Approach to Estimating Nitrous Oxide Emissions during Wetting Events from Single-Timepoint Flux Measurements.

Precipitation and irrigation induce pulses of NO emissions in agricultural soils, but the magnitude, duration, and timing of these pulses remain uncertain. This uncertainty makes it difficult to accurately extrapolate emissions from unmeasured time periods between chamber sampling events. Therefore, we developed a modeling protocol to predict NO emissions from data collected daily for 7 d after wetting events.
