Health effects stemming from animal feeding operations pollution in the contiguous United States are analyzed using a 20-year, county-level data set. Several quasi-experimental, potential outcome models are used to estimate the impact of high concentrations of animal units on mortality rates and other health and economic outcomes over a 20-year...
In agriculture there has been a long history of using a levy or an insurance premium to create mutual funds to mediate economic risks to growers due to environmental variability and quarantine pests. In the United States the federal government, through the USDA, continues to underwrite funds (collected by private...

With continual and worldwide human population growth, our impact on the natural environment expands and intensifies every day. We consume natural resources, burn fossil fuels, and release toxic compounds into the air, water, and earth. We build roads that fragment the landscape, construct new settlements, and develop agricultural lands in...
There is a great deal of evidence that altered sphingolipid metabolism is associated with fumonisin-induced
animal diseases including increased apoptotic and oncotic necrosis, and carcinogenesis in
rodent liver and kidney. The biochemical consequences of fumonisin disruption of sphingolipid
metabolism most likely to alter cell regulation are increased free sphingoid bases...
Background: Arsenic is an immunotoxicant. Clinical reports observe the reactivation of varicella zoster virus (VZV) in people who have recovered from arsenic poisoning and in patients with acute promyelocytic leukemia that have been treated with arsenic trioxide. Objective: We evaluated the association between arsenic and the seroprevalence of VZV IgG...
With the growing popularity of kinesiology at the undergraduate level, one would expect the field to be influential. Kinesiology, however, appears to be in a paradox. The undergraduate popularity is not reflected in the rest of academia, or even the general public, many of whom feel kinesiology is not a...

Under-5 mortality has decreased globally, but millions of children still die every year. In Bangladesh, respiratory infection and diarrheal disease remain leading causes of morbidity and mortality for children under-5, despite incredible progress in the past three decades. Immune system development begins in utero and continues into adulthood. Toxic environmental...
Detailed analysis of mixed-conifer and red fir forests were made from extensive, large vegetation sampling, systematically conducted throughout the Teakettle Experimental Forest. Mixed conifer is characterized by distinct patch conditions of closed-canopy tree clusters, persistent gaps and shrub thickets. This heterogeneous spatial structure provides contrasting microclimate, habitat and resource conditions...
Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire...

The condition of the sagebrush ecosystem has been declining in the Western United States, and greater sage-grouse (Centrocercus urophasianus), a sagebrush-obligate species, has experienced concurrent decreases in distribution and population numbers. This has prompted substantial research and management over the past two decades to improve the understanding of sage-grouse and...
Modern strains of broiler chickens are selected for fast growth and are marketed anywhere from 36 to 49 days after a 21-day incubational period. For a viable healthy chick, all the necessary nutrients required for growth and development must be provided by the hen through the fertilized egg. The current...
Blackberry pomace (BBP), a byproduct from juice processing, is often disposed of in landfills. We propose BBP as an antioxidant-rich feed supplement for transition dairy cows. To explore the effects of BBP on antioxidant status, 24 multiparous dairy cows (5 Holstein and 19 Jersey) were assigned randomly to one of...

Although the occurrence of ketosis is a postpartum phenomenon, recent studies have
focused on the prepartum period as key in the development of the disorder. Indicators of
prepartum energy status, such as depressed dry matter intake (DMI) and elevated plasma
non-esterified fatty acid (NEFA) concentrations have been associated with the...

The "cotton fur" (CF) condition in mink has been shown through
investigations at Oregon State University to have three basic causes,
viz.: 1) Feeding diets of fish comprising certain species of the cod
family, including: Pacific hake, Atlantic whiting and Alaskan pollock;
2) Inclusion of rancid fats in the diet;...
This paper discusses the issue of foodborne disease and international trade in food products from an economic perspective.
