Exposure to polycyclic aromatic hydrocarbons such as benzo[a]pyrene (B[a]P) has been determined to be a risk factor for various forms of human cancer. PAH DNA adducts have been shown to cause mutations, but carcinogenesis is also accompanied by alterations in gene expression. Inhibiting individual cytochrome P450s could clarify the interaction...
With increasing use of new pesticide formulations worldwide to repel and kill unwanted organisms, negative consequences on non-target species such as honey bees and other pollinators are of increasing concern and not well studied. This study compares the nanotechnology based pesticide (NBP) Safari and its base neonicotinoid, dinotefuran, and their...
Tomato flowers (Solanum lycopersicum) were used as a model system to investigate flower color modification by alteration of the carotenoid biosynthetic pathway, due to their ease of transformation and short time from seed to flowering. Tomato flowers are naturally bright yellow, primarily due to the accumulation of violaxanthin. Violaxanthin is...
An overview of how a variety of wild and managed bees and their pollination activities are affected by pesticide application. Provides guidelines for how beekeepers, growers and pesticide applicators can work together to prevent bee poisoning.
Honey bees (Apis mellifera) are responsible for approximately $17 billion in crop production per year in the United States, and are arguably the most important pollinators in the nation. The future of crop pollination and production is threatened by widespread national honey bee colony losses, which have averaged approximately 30%...
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...

Colorectal cancer (CRC), the third leading cause of cancer death in the USA, depends on early detection for patient survival. Early detection is improved with the identification of high risk individuals. Risk of CRC development is a complex interaction between an individual’s genetics and environmental exposures. Polycyclic Aromatic Hydrocarbons (PAHs)...

Drosophila suzukii (Diptera: Drosophilidae) is a devastating pest that attacks thin-skinned stone and small fruit in all major production regions of the United States and worldwide. D. suzukii first appeared in the United States in 2008 and is believed to be native to Southeast Asia. This vinegar fly has a...
