Cover Crops And Fertilization Alter Nitrogen Loss In Organic And Conventional Conservation Agriculture Systems, Rebecca E. Shelton, Krista L. Jacobsen, Rebecca L. Mcculley

Horticulture Faculty Publications

Agroecosystem nitrogen (N) loss produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, conservation agricultural management practices aimed at reducing N loss are increasingly adopted. However, the ecosystem consequences of these practices have not been well-studied. We quantified N loss via leaching, NH₃ volatilization, N₂O emissions, and N retention in plant and soil pools of corn conservation agroecosystems in Kentucky, USA. Three systems were evaluated: (1) an unfertilized, organic system with cover crops hairy vetch (Vicia villosa), winter wheat (Triticum aestivum), or a mix of the two (bi-culture); (2) an organic …

Interaction Of Cocoa Powder With Intestinal Microbiota, Zuyin Li

LSU Doctoral Dissertations

Cocoa powder contains polyphenolic compounds, which can provide potential health benefits to humans. The human gastroinestinal tract hosts diverse microorganisms which are called the human gut microbiota. These microbes can utilize carbohydrates through fermentation resulting in the production of short chain fatty acids (SCFAs), which cause a reduction of pH in gastroinestinal tract. The cocoa processing can change the composition of the carbohydrates, which can affect the fermentation patterns.

In this study we established an in vitro model system which simulated gastric digestion and colon fermentation. Five different processed cocoa samples (alkalized cocoa samples: D-11-B and D-11-S; non-alkalized cocoa samples: …

Mathematics, Physics, and Computer Science Faculty Articles and Research

Effects of curcumin, a biologically active ingredient of turmeric, were tested on the Ca²⁺transients induced by the activation of α₇ subunit of the human nicotinic acetylcholine (α₇nACh) receptor expressed in SH-EP1 cells. Curcumin caused a significant potentiation of choline (1 mM)-induced Ca²⁺ transients with an EC₅₀ value of 133 nM. The potentiating effect of curcumin was not observed in Ca²⁺ transients induced by high K⁺ (60 mM) containing solutions or activation of α₄β₂ nACh receptors and the extent of curcumin potentiation was not altered in the presence of …

Chemistry Faculty Publications

In this study, a novel galactomannoglucan named as TJ2 was isolated from Agaricus brasiliensis with microwave extraction, macroporous resin, ion exchange resin and high resolution gel chromatography. TJ2 is composed of glucose, mannose and galactose in the ratio 99.2:0.2:0.6. Infrared spectra (IR), methylation analysis and nuclear magnetic resonance spectra indicated that TJ2 mainly contained a b-(1?3) – linked glucopyranosyl backbone. Interestingly, TJ2 significantly promoted RAW264.7 cell proliferation, and was able to activate the cells to engulf E. coli. In addition, TJ2 induced the expression of Interleukin 1b (IL-1b), Interleukin 6 (IL-6), tumor necrosis factor a (TNF-a) and cyclooxygenase-2 (Cox-2) in …

Raíces Del Sur: Cultivating Ecofeminist Visions In Urban New Jersey, Renata Blumberg, Rosa Huitzitzilin, Claudia Urdanivia, Brian C. Lorio

Department of Nutrition and Food Studies Scholarship and Creative Works

Significant research has been devoted to analyzing community gardens, including their benefits and problems. This article contributes to debates about community gardens by using concepts from feminist geography and food justice research to reflect upon the challenges and possibilities of community gardening in small, peripheral cities with large immigrant populations. We argue that these concepts provide a useful framework to enact ecofeminist visions through community gardens, especially in places dominated by immigrant populations that are particularly marginalized in the present political era. Our case study garden, Raíces Del Sur, was located in the City of Passaic, a low-income, post-industrial urban …
