Background: Metals are known endocrine disruptors and have been linked to cardiometabolic diseases via multiple potential mechanisms, yet few human studies have both the exposure variability and biologically-relevant phenotype data available. We sought to examine the distribution of metals exposure and potential associations with cardiometabolic risk factors in the "Modeling the Epidemiologic Transition Study" (METS), a prospective cohort study designed to assess energy balance and change in body weight, diabetes and cardiovascular disease risk in five countries at different stages of social and economic development. Methods: Young adults (25-45 years) of African descent were enrolled (N = 500 from each …

Sampling Locality Is More Detectable Than Taxonomy Or Ecology In The Gut Microbiota Of The Brood-Parasitic Brown-Headed Cowbird (Molothrus Ater), Sarah M. Hird, Bryan C. Carstens, Steven W. Cardiff, Donna L. Dittmann, Robb T. Brumfield

Faculty Publications

Brown-headed Cowbirds (Molothrus ater) are the most widespread avian brood parasite in North America, laying their eggs in the nests of approximately 250 host species that raise the cowbird nestlings as their own. It is currently unknown how these heterospecific hosts influence the cowbird gut microbiota relative to other factors, such as the local environment and genetics. We test a Nature Hypothesis (positing the importance of cowbird genetics) and a Nurture Hypothesis (where the host parents are most influential to cowbird gut microbiota) using the V6 region of 16S rRNA as a microbial fingerprint of the gut from 32 cowbird …

Target Capture And Massively Parallel Sequencing Of Ultraconserved Elements For Comparative Studies At Shallow Evolutionary Time Scales, Brian Tilston Smith, Michael G. Harvey, Brant C. Faircloth, Travis C. Glenn, Robb T. Brumfield

Faculty Publications

Comparative genetic studies of non-model organisms are transforming rapidly due to major advances in sequencing technology. A limiting factor in these studies has been the identification and screening of orthologous loci across an evolutionarily distant set of taxa. Here, we evaluate the efficacy of genomic markers targeting ultraconserved DNA elements (UCEs) for analyses at shallow evolutionary timescales. Using sequence capture and massively parallel sequencing to generate UCE data for five co-distributed Neotropical rainforest bird species, we recovered 776-1516 UCE loci across the five species. Across species, 53-77% of the loci were polymorphic, containing between 2.0 and 3.2 variable sites per …

Effects Of Coastal Urbanization On Salt-Marsh Faunal Assemblages In The Northern Gulf Of Mexico, Michael R. Lowe, Mark S. Peterson

Faculty Publications

Coastal landscapes in the northern Gulf of Mexico, specifically the Mississippi coast, have undergone rapid urbanization that may impact the suitability of salt-marsh ecosystems for maintaining and regulating estuarine faunal communities. We used a landscape ecology approach to quantify the composition and configuration of salt-marsh habitats and developed surfaces at multiple spatial scales surrounding three small, first-order salt-marsh tidal creeks arrayed along a gradient of urbanization in two river-dominated estuaries. From May 3 to June 4, 2010, nekton and macroinfauna were collected weekly at all six sites. Due to the greater abundance of grass shrimp Palaemonetes spp., brown shrimp Farfantepenaeus …

An Ethanolic Extract Of Artemisia Dracunculus L. Regulates Gene Expression Of Ubiquitin-Proteasome System Enzymes In Skeletal Muscle: Potential Role In The Treatment Of Sarcopenic Obesity, Heather Kirk-Ballard, Gail Kilroy, Britton C. Day, Zhong Q. Wang, David M. Ribnicky, William T. Cefalu, Z. Elizabeth Floyd

Faculty Publications

Objective: Obesity is linked to insulin resistance, a primary component of metabolic syndrome and type 2 diabetes. The problem of obesity-related insulin resistance is compounded when age-related skeletal muscle loss, called sarcopenia, occurs with obesity. Skeletal muscle loss results from elevated levels of protein degradation and prevention of obesity-related sarcopenic muscle loss will depend on strategies that target pathways involved in protein degradation. An extract from Artemisia dracunculus, termed PMI 5011, improves insulin signaling and increases skeletal muscle myofiber size in a rodent model of obesity-related insulin resistance. The aim of this study was to examine the effect of PMI …

Optimization Of Hot Water Treatment For Sprout And Spoilage Inhibition Of Cured Sweet Potato, Ershad Sheibani, Taejo Kim, Dja Shin Wang, Juan L. Silva, Ramon Arancibia, Frank B. Matta, David Picha

Faculty Publications

The effect of hot water treatment on inhibition of sprouting and spoilage of cured sweet potatoes was investigated. The surface plot showed that as processing temperature and time of hot water treatment increased, spoilage increased until treated sweet potatoes showed 100% spoilage. The contour plot indicated that regardless of processing times (6-34min), minimal sprouting (20%) was observed between 55 and 62C. Hot water treatment below 50C increased sprouting up to 100%. The overlapped contour plot indicated that hot water treatment at 53-56C for less than 10min minimized spoilage (0-20%) and sprouting (30-50%) of cured sweet potatoes. Untreated sweet potatoes (control) …

Examining The Impact Of Multicollinearity In Discovering Higher-Order Factor Models, Colleen Schwarz, Andrew Schwarz, William C. Black Jan 2014

Examining The Impact Of Multicollinearity In Discovering Higher-Order Factor Models, Colleen Schwarz, Andrew Schwarz, William C. Black

Faculty Publications

Theory-driven structural equation modeling (SEM) is an increasingly popular technique for analyzing quantitative data in Information Systems research. Since 1994, 20% of all papers in top-tier journals use structural equation modeling [Urbach and Ahlemann, 2010]. Higher-order factor structures have been widely discussed from a number of theoretical perspectives [e.g., Bagozzi and Edwards, 1998; Hayduk, Ratner, Johnson and Bottorff, 1995; Law, Wong and Mobley, 1998]. Our intention is not to contradict these theoretical discussions but to postulate that empirical analysis can assist in the discovery of emergent higher-order structures where perhaps not initially proposed. As constructs have become both more numerous …

Coordination Deficits During Trunk-Assisted Reach-To-Grasp Movements In Parkinson's Disease, Miya K. Rand, Arend W.A. Van Gemmert, Abul B.M.I. Hossain, George E. Stelmach

Faculty Publications

The present study investigated how Parkinson's disease (PD) affects temporal coordination among the trunk, arm, and fingers during trunk-assisted reach-to-grasp movements. Seated participants with PD and healthy controls made prehensile movements. During the reach to the object, the involvement of the trunk was altered based on the instruction; the trunk was not involved, moved forward (flexion), or moved backward (extension) in the sagittal plane. Each of the trunk movements was combined with an extension or flexion motion of the arm during the reach. For the transport component, the individuals with PD substantially delayed the onset of trunk motion relative to …

Why State Prisons?, W. David Ball

Faculty Publications

The United States finds itself in an era where the cost of state prisons is both extremely large and politically salient. State prisons held approximately 1.3 million people in 2012, almost twice as many people as county jails and more than five times as many as federal prisons. The total cost of state corrections in2010 was $48.5 billion. In response, states nationwide are now experimenting with ways to reduce their role in imprisonment. The United States Department of Justice's Bureau of Justice Assistance launched the Justice Reinvestment Initiative to promote policies that reduce prison populations; the seventeen states that have …

Interspecific Competition Of A New Invasive Mosquito, Culex Coronator, And Two Container Mosquitoes, Aedes Albopictus And Cx. Quinquefasciatus (Diptera: Culicidae), Across Different Detritus Environments, D. A. Yee, J. F. Skiff

Faculty Publications

The mosquito Culex coronator (Dyar and Knab) (Diptera: Culicidae) has undergone rapid range expansion in the United States since 2003, with its historical distribution in the southwest expanding eastward to the Atlantic coast. Although Cx. coronator nominally use small natural aquatic habitats for development, the use of containers (e.g., tires) makes it potentially important as container invasive. To determine the potential ecological effects of Cx. coronator on resident container species, we conducted a laboratory experiment to assess its competitive ability with two common tire-inhabiting species, Aedes albopictus (Skuse) and Culex quinquefasciatus (Say) (Diptera: Culicidae). Larvae were reared under a factorial …
