Field scale measurement of greenhouse gas emissions from land applied swine manure

Frontiers of Environmental Science & Engineering 2017年第3期11卷 19-33页

Greenhouse gas emissions （GHGs） from swine production systems are relatively well researched with the exception of emissions from land application of manure. GttGs inventories are needed for process- based modeling and science-based regulations. Thus, the objective of this observational study was to measure GHG fluxes from land application of swine manure on a typical corn field. Assessment of GHG emissions from deep injected land-applied swine manure, Phil and reapplication in the spring, on a typical US Midwestern corn-on-corn farm was completed. Static chambers were used Ibr flux measurement along with gas analysis on a GC-FID-ECD＋ Measured gas concentrations were used to estimate GHGs flux using four different models： linear regression, nonlinear regression, first order linear regression and the revised Hutchinson and Mosier （HMR） model, respectively for *** flux esmnates after manure apphcatmn of 5.85×10 g·ha^-1（1 ha = 0.01 km） of CO2 6.60×10^1g·ha^-1 of CH4 and3.48 ×10^3g·ha^-1 N2O for the fall trial and 3.11×10^6g·ha^-1 of CO2,2.95×10^3g·ha^-1 of OH4, and 1.47×10^4g·ha^-1 N2O after the spnng reapphcation trial were observed. The N2O net cumulative flux represents 0.595% of nitrogen applied in swine manure for the fall trial.

Glutamine-released ammonia acts as an unprecedented signaling molecule activating lipid production

引用

Genes & Diseases 2023年第2期10卷 307-309页

作者： Chunming Cheng Scott kelsey Deliang Guo Department of Radiation Oncology Ohio State Comprehensive Cancer CenterArthur G. James Cancer Hospital and Richard J.

In healthy humans, ammonia circulates in the bloodstream at a concentration around 11–32 μmol/l. Whether ammonia plays any physiological role has been unknown until a recent report published in Nature Metabolism.1 Ammonia, long thought to be a toxic waste product of amino acid metabolism, needs to be excreted from the human body as urea. Intriguingly, in this paper, Cheng et al1 for the first time reported that ammonia is not a waste product;rather, it is an unprecedented signaling molecule tying glucose and glutamine to lipid production in human cells. This study revealed that ammonia released from glutamine triggers a cascade of cellular processes leading to the activation of lipogenesis machinery for lipid production (Fig. 1). This discovery has major implications for developing treatments for human diseases such as cancers and metabolic syndromes, as dysregulated metabolism is a hallmark of these diseases.
