Overcoming the seasonal variations in fitness of the amphipod Corophium Volutator as an environmental toxicology test species using laboratory cultured specimens.
The marine amphipod Corophium volutator is an important source of food for many fish and wading birds, making it an important species in an estuarine environment and a relevant toxicological test species. Historical data has indicated that seasonal variations in the fitness of C. volutator may make …

Public Ecology: Linking People, Science, and the Environment
… to resolve today's complex and controversial environmental issues (e.g., biodiversity loss, global warming, cultural evolution, etc.). In response to these concerns, a variety of applied science programs have emerged to help people make better decisions about the environment. Each of these …

Novel Roles of the Aryl Hydrocarbon Receptor in Normal Physiology and Epigenetic Reprogramming
… AhR has classically been associated with environmental toxicology owing to the fact it mediates the toxic effects of halogenated aromatic hydrocarbons and environmental pollutants such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). TCDD exposure in laboratory animals is linked to …

Unresolved complex mixtures of aromatic hydrocarbons in the marine environment : toxicity, solubility and photodegradation studies
… hydrocarbons have been found in a wide range of environmental matrices at high concentrations. However, limited consideration has been given to the potential detrimental effects of the accumulation of these compounds in the marine environment. In particular, there is a need to evaluate these …

Use of solid-phase microextraction to detect semiochemicals in synthetic and biological samples
… was previously used in the fields of environmental toxicology and food science to identify contaminants and was only recently applied to the fields of insect and mammalian semiochemicals. Solid-phase microextraction provides many benefits, namely the ability to detect unstable volatile …

CYTO-GENOTOXIC EFFECTS OF SOME PHARMACEUTICAL AND PERSONAL CARE PRODUCTS (PPCPS) ON THE FRESHWATER BIVALVE ZEBRA MUSSEL (DREISSENA POLYMORPHA)
… care products (PPCPs) are an emerging class of environmental pollutants that are extensively and increasingly being used in human and veterinary medicine. Due to their continuous production, consumption and often abuse, many studies have shown worldwide measurable concentrations of about 100 of …

An informatics approach to prioritizing risk assessment for chemicals and chemical combinations based on near-field exposure from consumer products
… simultaneous or sequential exposure to multiple environmental stressors can affect chemical toxicity. Cumulative risk assessments consider multiple stressors but it is impractical to test every chemical combination and environmental stressor to which people are exposed. The goal of this research …

Awareness effects lead contamination in Zambia's Makululu and Kasanda Mine Compounds of Kabwe District
The principal areas and causes of environmental degradation include land degradation through erosion, land, air and water pollution to mention only but a few. Many of these environmental issues emanate from mining activities in one way or the other. Although these environmental concerns are …

Metal exposure in non-occupationally exposed pregnant women of Western Australia and contribution of environmental sources
… to their exposure. Studies have shown that environmental media are potential sources of metals exposure for humans, and exposure in the general population can occur through inhalation of contaminated air, ingestion of contaminated drinking water and food, or by dermal contact. This study is …

Understanding environmental influences on bioaccumulation of contaminants of emerging concern among fish species.
… and potential to negatively affect human and environmental health. These chemicals have physicochemical properties which make traditional tools for assessing bioaccumulation, like log KOW, difficult, as both groups can be ionized at environmentally relevant pHs. Therefore, I aim to better …

Ecotoxicology and environmental education in the development of a turtle conservation program in Southeastern Tennessee
… expanded its initiative to include ecotoxicology and environmental education components. The goals of these components were three-fold. The first objective was to determine the presence and concentration of persistent organic pollutants (POPs) in the plasma of a riverine turtle …

Biomarkers of Human Exposure and Effect to Petrogenic Polycyclic Aromatic Hydrocarbons
Safety of seafood harvested from the Gulf of Mexico has been a primary concern since the 2010 Deepwater Horizon (DWH) oil spill. Petrogenic polycyclic aromatic hydrocarbons (PAHs) found in crude oil have the potential to bioaccumulate in seafood and render consumers vulnerable to adverse health …

Modeling Epithelial Ovarian Cancer In The Mouse
For over five decades epithelial ovarian cancer (EOC) is identified as the leading cause of death from gynecological malignancies in the USA. Unfortunately, due to latent progression of EOC and lack of accurate animal models studies of this disease's pathogenesis have been challenging. Not …

Signal Regulation By Cd38, Lyn, And Mapk-Associated Molecules During All-Trans Retinoic Acid-Induced Differentiation Of Acute Myelogenous Leukemia Cells
All-trans retinoic acid (ATRA) is successful in treating acute promyelocytic leukemia but has shown limited success with other cancers. Identifying signaling pathways that confer ATRA responsiveness and compounds that enhance the effects of the drug could expand its therapeutic efficacy. The …
