The Smell Of Hopelessness, Juline Cariba Rachel Party Dec 2015

The Smell Of Hopelessness, Juline Cariba Rachel Party

Capstones

Rafts of sargassum seaweed kilometers wide have been invading the Caribbean for more than five years, but 2015 was the worst. Tons of seaweed stretch from Texas south to Trinidad and Tobago, with the Lesser Antilles suffering the most damage. Residents near beaches are exposed to an insidious and pernicious danger, scientists say, from fumes that smell like rotten eggs, emitted by the decaying algae. The odor also drives tourists away from beaches and restaurants, and the tourism economy is collapsing.Amid the algae crisis, an elderly woman, Virginie Mark, is trying to survive. She struggles with her health, finances and …


Impact Of Executive Order 13211 On Environmental Regulation: An Empirical Study, Elizabeth Ann Glass Geltman Dec 2015

Impact Of Executive Order 13211 On Environmental Regulation: An Empirical Study, Elizabeth Ann Glass Geltman

Publications and Research

A great deal has been written about the Energy Policy Act of 2005 exempting oil and gas operations using hydraulic fracturing from the purview of certain federal environmental laws. Far less attention has been paid to George W. Bush’s Executive Order 13211 (EO 13211), entitled “Actions Concerning Regulations that Significantly Affect Energy Supply, Distribution or Use.” The executive order requires federal agencies to evaluate the impact of federal regulations on “supply, distribution and use of energy.” This study examined the impact of EO 13211 on United States environmental and conservation regulations proposed and promulgated by federal agencies. The study found …


Nitric Oxide-Releasing Aspirin Suppresses Nf-Κb Signaling In Estrogen Receptor Negative Breast Cancer Cells In Vitro And In Vivo, Niharika Nath, Mitali Chattopadhyay, Deborah B. Rodes, Anna Nazarenko, Ravinder Kodela, Khosrow Kashfi Jul 2015

Nitric Oxide-Releasing Aspirin Suppresses Nf-Κb Signaling In Estrogen Receptor Negative Breast Cancer Cells In Vitro And In Vivo, Niharika Nath, Mitali Chattopadhyay, Deborah B. Rodes, Anna Nazarenko, Ravinder Kodela, Khosrow Kashfi

Estrogen receptor negative (ER(−)) breast cancer is aggressive, responds poorly to current treatments and has a poor prognosis. The NF-κB signaling pathway is implicated in ER(−) tumorigenesis. Aspirin (ASA) is chemopreventive against ER(+) but not for ER(−) breast cancers. Nitric oxide-releasing aspirin (NO-ASA) is a safer ASA where ASA is linked to an NO-releasing moiety through a spacer. In vitro, we investigated anti-proliferation effects of NO-ASA (para- and meta-isomers) against ER(−) breast cancer cells MDA-MB-231 and SK-BR-23, effects on NF-κB signaling, and reactive oxygen species by standard techniques. In vivo, effects of NO-ASA were evaluated in a mouse xenograft model …
