Investigating the effects of harvest time and light exposure on cannabinoid potency in industrial hemp (Cannabis sativa) using UPLC-diode array detection

Creator:: Saindon, Ashley L.
Abstract:: Five varieties of industrial hemp (Cannabis sativa) were grown in the field in Imperial Valley, CA, USA in order to determine whether light conditions or harvest times influence cannabinoid content. A total of 16 cannabinoids were investigated in this study: Delta-9-tetrahydrocannibinol (THC-d9), Delta-9-tetrahydrocannibinolic acid (THC-a), Cannabidiol (CBD), Cannabidiolic acid (CBD-a),...

Determination of flavin-containing monooxygenase mRNA levels in mouse lung and liver

Creator:: Lo, Pachida C.
Abstract:: We are developing a flavin-containing (Fmo) knock-out mouse for Fmo2 that will be utilized to elucidate the role of active human FMO isoform 2 (FMO2.1) in xenobiotic metabolism and toxicity. Since FMO2 is primarily expressed in lung this will provide information on how 27% of African-Americans and 5% of Hispanics...

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

Analyzing the use of the acellular DCFH assay as a means of determining oxidative stress induced in zebrafish embryos exposed to lanthanide oxide nanoparticles

Creator:: Engstrom, Arek
Abstract:: The ability of nanoparticles (NPs) to induce oxidative stress on organisms has been linked to NP cytotoxicity and genotoxicity for a variety of organisms. One proposed mechanism of this increased oxidative stress is the ability of NPs to generate reactive oxygen species (ROS). Due to the dynamic nature and small...

Honey Bees (Apis mellifera) and Agricultural Chemicals: Global to Micro Perspectives

Creator:: Bernert, Ann
Abstract:: Fungicide sensitivity of honey bee associated fungi Abstract - Honey bees are exposed to a wide range of pesticides while pollinating agricultural crops. These pesticides residues are found in beeswax, nectar and pollen in the hive. Some of the pesticides found are fungicides which are not generally considered harmful to...

Understanding polycyclic aromatic hydrocarbon (PAH) toxicity and inflammation in human bronchial epithelial cells

Creator:: Valdez, Teresa
Abstract:: There is increased emphasis on understanding cumulative risk from the combined effects of chemical and non-chemical stressors as it relates to public health. Recent animal studies have identified pulmonary inflammation as a possible modifier and risk factor for chemical toxicity in the lung after exposure to inhaled pollutants; however, little...

Analysis of Chemical Leaching from Common Consumer Plastic Bottles Under High Stress Conditions

Creator:: Dornath, Paul John
Abstract:: There has been much controversy in recent years over the leaching of chemicals from plastic water bottles. In this study, two of the most common plastics used in water bottles, polyethylene terphthalate (PETE) and polycarbonate (PC) were studied. The leaching of the chemical bisphenol-A (BPA) from polycarbonate (Nalgene ™, Camelback...

Effects of Xanthohumol on Biomarkers of Metabolic Syndrome in Obese Rats

Creator:: Moreno Luna, Arlyn Y.
Abstract:: Flavonoids are a large family of compounds synthesized by plants that have a common chemical structure. It is believed that the health effects of fruits and vegetables are primarily due to dietary flavonoids content. Current research indicates that dietary flavonoids show promise for mitigating and/or preventing chronic conditions associated with...

Reduced toxicity of benzethonium chloride to Escherichia coli through adsorption onto titanium dioxide nanoparticles

Creator:: Waldron, Kerri Raven
Abstract:: Antimicrobial agents are being increasingly used in consumer soaps and detergents, despite a lack of data demonstrating their efficacy in such products. This study investigated the nature of the interaction between different crystalline structures of titanium dioxide nanoparticles and BTC, and explore which structure, if any, could be best used...

Influence of Corexit 9500A and Alaska North Slope Crude oil toxicity to the ammonia-oxidizing bacteria, Nitrosomonas europaea, and the ammonia-oxidizing archaea, Nitrosopumilus maritimus

Creator:: Schneider, Margaret C.
Abstract:: The inhibitory effects of Corexit 9500A, Alaska North Slope Crude oil (ANSC), and mixtures of the two on the ammonia-oxidizing bacteria, Nitrosomonas europaea, and the ammonia-oxidizing archaea, Nitrosopumilus maritimus, were investigated. Corexit 9500A was found to be minimally toxic to both microorganisms with concentrations of 2000 and 3000 ppm yielding...
