Repeated short-term intranasal instillation of lupus-prone mice with to crystalline silica (cSiO2) induces inflammatory gene expression and ectopic lymphoid neogenesis in the lung, leading to early onset of systemic autoimmunity and rapid progression to glomerulonephritis. These responses are suppressed by dietary supplementation with the ω-3 polyunsaturated fatty acid docosahexaenoic acid (DHA). Here, we tested the hypothesis that dietary DHA supplementation suppresses cSiO2-induced inflammatory proteins in bronchoalveolar alveolar lavage fluid (BALF) and plasma of lupus-prone mice. Archived tissue fluid samples were used from a prior investigation in which 6 wk-old lupus-prone female NZBWF1 mice were fed isocaloric diets containing 0 or …

How To Stuff A Duck: Learning Artisan Foie Gras Production In France, Jean Lavigne

Environmental Studies Faculty Publications

I have always hated the taste of liver. Calf’s liver, chicken liver, liverwurst, any kind of pâté that contains even a small amount of liver—for me, the taste is repulsive. I was once served a rabbit’s liver at a family meal in Italy, the prize morsel that is offered to guests; I choked it down with an unconvincing “Grazie.” I never imagined I would come to like a specific kind of liver enough to prepare it myself at home, much less to spend six weeks with an artisan foie gras producer in Southwestern France learning how to produce it from …

Analysis Of Total Acidity Toward Bacterial And Endophytic Fungi Profile Dur-Ing Black Garlic Processing From Garlic (Allium Sativum L.) And Shallot (Allium Ascalonicum L.), Ayu Rahmania Lestari, Surjani Wonorahardjo, Suharti Suharti

Makara Journal of Science

Black garlic or shallot are products of processed garlic and shallots obtained through a heating process conducted over a certain period. Black garlic/shallots have a mild aroma with a sweet and sour taste. The heating process causes chemical compound transition in the garlic, including acidity. In addition to the chemical process, the garlic’s color and component changes are due to the role of microorganisms during black garlic processing. However, the presence and function of such microorganisms have not been identified. Therefore, this research explores the black garlic’s microorganisms, their role in black garlic processing, and their relation to the total …
