Soil Carbon Dioxide Equivalent Emissions and Theoretical Ethanol Yield from Midwestern Bioenergy Systems Open
There has been a significant demand to increase biofuel production and usage in the USA. Bioenergy crops also have the potential to mitigate greenhouse gas (GHG) emissions from agricultural systems but crop type (annual vs. perennial) may …

The LTAR Cropland Common Experiment in the Lower Mississippi River Basin Open
The Lower Mississippi River Basin Long‐Term Agroecosystem Research Site (LMRB‐LTAR) encompasses six states from Missouri to the Gulf of Mexico and is coordinated by the USDA‐ARS National Sedimentation Laboratory, Oxford, MS. The overarchin…

Comparative analysis of three next-generation sequencing techniques to measure nosZ gene abundance in Missouri claypan soils Open
Quantitative next-generation sequencing techniques have been critical in gaining a better understanding of microbial ecosystems. In soils, denitrifying microorganisms are responsible for dinitrogen (N2) production. The nosZ gene codes for …

Cover crop impacts on nitrogen losses and environmental damage cost Open
There is a need to explore management practices that reduce nitrate (NO3-) leaching and aid in meeting current greenhouse gas reduction goals. Tile drainage involves using perforated pipes to remove excess subsurface water from agricultura…

Spatial variability of denitrification enzyme activity and actual denitrification emissions on Missouri claypan soils Open
Denitrification in agricultural soils is responsible for the majority of anthropogenic N 2 O production. The objective of this research was to assess denitrification potential and the spatial dependence of soil N 2 O flux from claypan soil…

Development of the LYVE‐1 gene with an acidic‐amino‐acid‐rich (AAAR) domain in evolution is associated with acquisition of lymph nodes and efficient adaptive immunity Open
CRSBP‐1 (mammalian LYVE‐1) is a membrane glycoprotein highly expressed in lymphatic endothelial cells (LECs). It has multiple ligands, including hyaluronic acid (HA) and growth factors/cytokines (e.g., PDGF‐BB and VEGF‐A) containing CRS mo…

Urea Fertilizer Placement Impacts on Corn Growth and Nitrogen Utilization in a Poorly-Drained Claypan Soil Open
Practices to increase nitrogen (N) use efficiency (NUE) include selecting appropriate N fertilizer sources and application methods, but minimal research has focused on these practices in poorly-drained claypan soils which are prone to N lo…

7‐Dehydrocholesterol (7‐DHC), But Not Cholesterol, Causes Suppression of Canonical TGF‐β Signaling and Is Likely Involved in the Development of Atherosclerotic Cardiovascular Disease (ASCVD) Open
For several decades, cholesterol has been thought to cause ASCVD. Limiting dietary cholesterol intake has been recommended to reduce the risk of the disease. However, several recent epidemiological studies do not support a relationship bet…

A sign on CT that predicts a hazardous ureteral anomaly Open
Anterior deviation of the ureter in its mid-course appears to predict inguinoscrotal herniation of the ureter. This finding is a sensitive predictor and should raise concern for this anomaly in the appropriate clinical setting. It is not e…
