David Money and Jerald B. Johnson, Department of Biology Our study takes advantage of a unique species pair within Brachyrhaphis, Brachyrhaphis roseni and B. terrabensis,, which provides insight into how divergence proceeds once speciation is complete. Brachyrhaphis roseni and B. terrabensis are sister species that occur in the same river drainages throughout northwestern Panama. A […]

The ‘Ohana MANA Challenge: An Intervention Study on Native Hawaiian and Pacific Islander Nutrition and Activity
Jane H Lassetter, Nursing Abstract In our recent study, 84.4% of Native Hawaiian and Pacific Islanders (NHPIs) in Hawaii and Utah were overweight or obese, which puts them at increased risk for obesity-related diseases, including cardiovascular disease, diabetes, and some cancers. Pre-colonization NHPI diets were rich in fresh fruits and vegetables and fish, but research […]
Attention Deficit Hyperactivity Disorder, Medication, and Risk of Injury
Michelle Steele and Ray M. Merrill, PhD, MPH, Department of Health Science Introduction Attention deficit hyperactivity disorder is a known disorder that mainly effects children but can carry on into adulthood. It is characterized by difficulty focusing, sustaining attention, and controlling behaviors. These characterizations can cause a person with ADHD to have a more difficult […]
Barriers to Civil Society Activity
Taylor Malia Richards and Dr. Darren Hawkins, Department of Political Science Foreign aid, and aid effectiveness, has been one of the most heated debates in international relations and US foreign policy in the past several decades. Is aid ever effective? Under what conditions? At stake are billions of dollars and, potentially, millions of lives and […]
Statistical Survey Of International Terrorist Activity: An Examination Of The Effectiveness Of Military Deterrence
Eric R. Jorgensen and Dr. Jay Goodliffe, Political Science As we recently observed the one-year anniversary of the embassy bombings in Africa, thoughts turned again to our vulnerability to terrorist attacks. One year ago President Clinton vowed to “wage war on terrorism.” It was at this point that many began to question the effectiveness of […]
The Effects of Maternal Separation on Lymphocyte Activity in Rats
Patrick R. Olson and Dr. Reuben Ward Rhees, Zoology We have been investigating how stress affects physiological development. My interest dealt with the effects of stress on the immune system. Lymphocyte proliferation is a common measurement of immune function. A new paradigm for stress is being used dealing with maternal separation, performed under the ethical […]
Expression, Activity and Inhibition of Canine Cyclooxygenase
Joel Ellis Wilson and Dr. Dan Simmons, Chemistry and Biochemistry Nonsteroidal anti-inflammatory drugs (NSAIDs) exhibit their effect by inhibiting the cyclooxygenase (COX) enzymes. However, inhibition of both COX-1 and COX-2 by the administration of NSAIDs to both humans and animals often leads to negative side effects, most commonly gastric toxicity, including ulcers, which may progress […]
Selenium Supplementation does not affect the Activity of the Enzyme 8-oxoguanine DNA Glycosylase
Benjamin J. Wycherly and Dr. Merrill Christensen, Food Science and Nutrition Highly reactive oxygen species produce DNA lesions, which are postulated to cause cancer. A particularly common lesion is that of an oxidized guanine residue, 8-hydroxyguanine (8-OHdG). This base is of particular concern because it can mispair with adenine during replication causing a mutation from […]
Evaluation of The Activity of Cationic Steroid Antibiotics
David W. Swenson and Dr. Paul B. Savage, Chemistry and Biochemistry Food-borne illnesses are a continuing problem in the US [1]. Gram-positive and Gram-negative bacteria pose significant threats to the integrity of the food supply and to the health of the public. For example, according to statistics from the Centers for Disease Control, an estimated […]
The Brain’s Response to Physical Activity Studied With fMRI
Ren Weidman and Dr. Travis Oliphant, Electrical and Computer Engineering In recent years the fields of medicine and physiological research have made many advancements as a result of application of technology. One example of this is the device known as the Magnetic Resonance Imaging machine (MRI). MRI machines use innovative methods based on principles of […]
