Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Corruption In Capsules: How It Is Legal For Companies To Put Harmful Ingredients In Vitamins And Dietary Supplements, Emily Leggiero

English Department: Research for Change - Wicked Problems in Our World

The vitamin and supplement industry has increased exponentially in profits as well as potential products on the market since the turn of the century. However, these products are not regulated, nor do they undergo any premarket clinical research or testing. Public health is compromised by vitamins and supplements that are available for American consumption that is disproportionately unregulated to their chemically similar counterparts. This wicked problem is facilitated through the combination of historical legislative definitions that has since been distorted for corrupt administrative gain through the allotment of corporate expenditures. Company disbursements are made to the same policymakers that create …

Assessment Of The Effects Of Caffeine, Gallic Acid, And Epigallocatechin-3-Gallate On Cell Inhibition, Pim-3 And E. Cadherin Protein Levels In Two Lines Of Pancreatic Cancer Cells, Lena Haddad, Melissa Rowland-Goldsmith

Student Scholar Symposium Abstracts and Posters

According to the American Cancer Society, pancreatic cancer is currently the fourth leading cause of cancer related deaths in the United States. In addition to being an exceptionally aggressive form of cancer, it is particularly difficult to treat because it is usually diagnosed in late stages after the onset of metastasis (1). Consequently, the current treatments used, including chemotherapy and radiation, have been rendered ineffective (2). As a result, focus has been placed on using dietary alternatives which are known to possess chemopreventive properties (3). Previous studies have indicated that Gallic acid (an important phytochemical in pomegranates) and Epigallocatechin-3-Gallate (the …

Iron Regulatory Protein 1 Is Not Required For The Modulation Of Ferritin And Transferrin Receptor Expression By Iron In A Murine Pro-B Lymphocyte Cell Line, Kevin Schalinske, Kenneth P. Blemings, Daniel W. Steffen, Opal S. Chen, Richard S. Eisenstein

Kevin Schalinske

Iron regulatory proteins (IRPs) are cytoplasmic RNA binding proteins that are central components of a sensory and regulatory network that modulates vertebrate iron homeostasis. IRPs regulate iron metabolism by binding to iron responsive element(s) (IREs) in the 5* or 3* untranslated region of ferritin or transferrin receptor (TfR) mRNAs. Two IRPs, IRP1 and IRP2, have been identified previously. IRP1 exhibits two mutually exclusive functions as an RNA binding protein or as the cytosolic isoform of aconitase. We demonstrate that the BayF3 family of murine pro-B lymphocytes represents the first example of a mammalian cell line that fails to express IRP1 …

The Isolation And Identification Of Polyphenolics From Grape Seeds And Their Activity Towards Specific Cell Lines, Joseph A. Reddy

Chemistry & Biochemistry Theses & Dissertations

Grape seed extract is being marketed in France for cardiovascular use and skin care. The active constituents of both these drugs are certain polyphenols called procyanidins. A similar seed extract has now been obtained from Virginia Chardonnay grape seeds. Ten of the major components in this extract have been isolated in their pure form by the semi-preparative HPLC separation on a YMC ODS-AQ (Octadecylsilane-AQ) column. The ODS-Aq column has been shown to have a better resolving capacity compared to the Spherisorb ODS (Octadecylsilane) column previously described in the literature. This has been attributed to the ODSAQ support which has both …
