Faculty Publications

Objective: To explore potential interactions between folate-cycle factors and Helicobacter pylori seropositivity in the prediction of cognitive function. Methods We used data obtained from the 1999–2000 continuous National Health and Nutrition Examination Survey produced by the United States’ Centers for Disease Control and Prevention. Using Ordinary Least Squares regression, we tested for associations between multiple folate-cycle factors, Helicobacter pylori seropositivity, and cognitive function assessed by the digit symbol coding subtest of the Wechsler Adult Intelligence Scale-III. We then tested for interactions between each of the folate-cycle factors and Helicobacter pylori in the prediction of cognitive function.

Results: Although Helicobacter pylori …

Independent Association Of Resting Energy Expenditure With Blood Pressure: Confirmation In Populations Of The African Diaspora, Chloe Creber, Richard S. Cooper, Jacob Plange-Rhule, Pascal Bovet, Estelle V. Lambert, Terrence E. Forrester, Dale Schoeller, Walter Riesen, Wolfgang Korte, Guichan Cao, Amy Luke, Lara R. Dugas

Faculty Publications

Background: Obesity is a major risk factor for hypertension, however, the physiologic mechanisms linking increased adiposity to elevations in blood pressure are not well described. An increase in resting energy expenditure (REE) is an obligatory consequence of obesity. Previous survey research has demonstrated that REE is an independent predictor of blood pressure, and eliminates the co-linear association of body mass index. This observation has received little attention and there have been no attempts to provide a causal explanation. Methods: At baseline in an international comparative study on obesity, 289 participants aged 25-44 were recruited from communities in the US, the …

We studied …

The Application Of An Implementation Science Framework To Comprehensive School Physical Activity Programs: Be A Champion!, Justin B. Moore, Russell L. Carson, Collin A. Webster, Camelia Renee Singletary, Darla M. Castelli, Russell R. Pate, Michael W. Beets, Aaron Beighle

Faculty Publications

Comprehensive school physical activity programs (CSPAPs) have been endorsed as a promising strategy to increase youth physical activity (PA) in school settings. A CSPAP is a five-component approach, which includes opportunities before, during, and after school for PA. Extensive resources are available to public health practitioners and school officials regarding what should be implemented, but little guidance and few resources are available regarding how to effectively implement a CSPAP. Implementation science provides a number of conceptual frameworks that can guide implementation of a CSPAP, but few published studies have employed an implementation science framework to a CSPAP. Therefore, we developed …

Metavirome Sequencing Of The Termite Gut Reveals The Presence Of An Unexplored Bacteriophage Community, Chinmay V. Tikhe, Claudia Husseneder

Faculty Publications

The Formosan subterranean termite; Coptotermes formosanus is nutritionally dependent on the complex and diverse community of bacteria and protozoa in their gut. Although, there have been many studies to decipher the taxonomic and functional diversity of bacterial communities in the guts of termites, their bacteriophages remain unstudied. We sequenced the metavirome of the guts of Formosan subterranean termite workers to study the diversity of bacteriophages and other associated viruses. Results showed that the termites harbor a virome in their gut comprised of varied and previously unknown bacteriophages. Between 87-90% of the predicted dsDNA virus genes by Metavir showed similarity to …

Teens As Teachers In The Garden: Cultivating A Sustainable Model For Teaching Healthy Living, Virginia Bolshakova, John Gieng, C. Sheena Sidhu, Mary Vollinger, Lorena Gimeno, Jessica Guild

Faculty Publications

School gardens are an ideal space to deliver a healthy living curriculum, such as nutrition and physical activity education, to elementary school youth. However, public schools often lack the resources and support to establish sustainable garden-based programming. We created the Healthy Living Ambassador program, a collaborative after-school garden program in low-income communities that brought together resources from schools, community programs, and University of California Cooperative Extension. This school garden program featured culturally competent teens as teachers to serve as near-peer educators and mentors to elementary school youth. The program development model incorporated lessons from sustainable community-based health program interventions and …

Developmentally Appropriate Practice In The 21st Century, Kay Sanders, Flora Farago

Faculty Publications

Developmentally appropriate practice (DAP) is a set of early childhood curricular recommendations published by the National Association for the Education of Young Children (NAEYC). DAP was introduced in the United States in the late 1980s through Bredekamp’s (1987) seminal work, “Developmentally Appropriate Practice in Early Childhood Programs Serving Children from Birth through Age 8.” Since the initial publication, DAP has been widely accepted as the standard for early childhood educational practice in the United States and in Westernized countries around the world. Whereas proponents of DAP assert its positive influence on children, those more critical of DAP question whether it …

Social Medicine And International Expert Networks In Latin America, 1930–1945, Eric D. Carter

Faculty Publications

This paper examines the international networks that influenced ideas and policy in social medicine in the 1930s and 1940s in Latin America, focusing on institutional networks organised by the League of Nations Health Organization, the International Labour Organization, and the Pan-American Sanitary Bureau. After examining the architecture of these networks, this paper traces their influence on social and health policy in two policy domains: social security and nutrition. Closer scrutiny of a series of international conferences and local media accounts of them reveals that international networks were not just ‘conveyor belts’ for policy ideas from the industrialised countries of the …

Big Data Analytics: What Can Go Wrong, Sharona Hoffman

Faculty Publications

It is not uncommon to read that long-held beliefs about medical treatments have been dislodged by new studies. For example, there is now doubt as to whether women should undergo annual mammograms, previously a cornerstone of cancer screening. Hormone replacement therapy for menopausal women, once considered highly suspect in light of worrisome research findings, is now being reconsidered as a beneficial therapy. These reversals trouble and confuse many Americans.

This Article explores why medical research findings can be erroneous and what can go wrong in the process of designing and conducting research studies. It provides readers with essential analytical tools …

Surface And Subsurface Tillage Effects On Mine Soil Properties And Vegetative Response, H. Z. Angel, Jeremy Stovall, Hans Michael Williams, Kenneth W. Farrish, Brian P. Oswald, J. L. Young

Faculty Publications

Soil compaction is an important concern for surface mine operations that require heavy equipment for land reclamation. Excessive use of rubber-tired equipment, such as scraper pans, may cause mine soil compaction and hinder the success of revegetation efforts. However, information is limited on management strategies for ameliorating the potential compacting effects of scraper pans, particularly during site preparation for loblolly pine (Pinus taeda L.) plantations. Three forms of tillage and one control were replicated five times on surface mined land in the west Gulf Coastal Plain: no tillage (NT), disking (D), single-ripping + disking (R+D), and cross-ripping + disking …

Centralized Review Of Tax Regulations, Clinton G. Wallace

Faculty Publications

Centralized oversight of agency policymaking and spending by the President’s Office of Management and Budget is a hallmark of the modern administrative state. But tax regulations have almost never been subject to centralized review. The Trump administration recently proposed to require centralized review of tax regulations, but it is unclear what regulations would be subject to such review or how it would be conducted.

This Article examines the normative desirability of the longstanding approach of exempting tax regulations from centralized review, and the alternative of imposing such review. Scholars and policymakers have provided various incomplete justifications for excepting tax policy …

Serving Up Allergy Labeling: Mitigating Food Allergen Risks In Restaurants, Marie C. Boyd

Faculty Publications

Allergens in restaurant food cause many allergic reactions and deaths. Yet no federal, state, or local law adequately protects people from these harms. Although federal law requires the labeling of “major food allergens” in packaged food, there are no allergen labeling requirements for restaurant-type food. In addition, existing food safety requirements for restaurants are inadequate to prevent allergen cross contact.

The existing legal scholarship on food allergens in restaurants is limited. Much of the legal scholarship on labeling in restaurants focuses on menu labeling — the provision of calorie and other nutrition information to combat obesity. The requirements of Section …

Characterization Of Prostate Cancer Cell Progression In Zebrafish Xenograft Model, Wei Xu, Brittany A. Foster, Mackenzie Richards, Kenneth R. Bondioli, Girish Shah, Christopher C. Green

Faculty Publications

Early diagnosis of prostate cancer (PCa) is critical for the application of efficient treatment to PCa patients. However, the majority of PCas remains indolent from several months to several years before malignancy. Current diagnosis methods have limitations in their reliability and are inefficient in time cost. Thus, an efficient in vivo PCa cell xenograft model is highly desired for diagnostic studies in PCas. In the present study we present a standardized procedure to create a PCa cell xenograft model using zebrafish (Danio rerio) as the host. PC3-CTR cells, a cell line from adenocarcinoma with stable expression of calcitonin receptor (CRT), …

Ex Vivo Gut Culture For Studying Differentiation And Migration Of Small Intestinal Epithelial Cells, Xiaofei Sun, Xing Fu, Min Du, Mei Jun Zhu

Faculty Publications

© 2018 The Authors. Epithelial cultures are commonly used for studying gut health. However, due to the absence of mesenchymal cells and gut structure, epithelial culture systems including recently developed three-dimensional organoid culture cannot accurately represent in vivo gut development, which requires intense cross-regulation of the epithelial layer with the underlying mesenchymal tissue. In addition, organoid culture is costly. To overcome this, a new culture system was developed using mouse embryonic small intestine. Cultured intestine showed spontaneous peristalsis, indicating the maintenance of the normal gut physiological structure. During 10 days of ex vivo culture, epithelial cells moved along the gut …

Medical Implications Of Space Radiation Exposure Due To Low-Altitude Polar Orbits, Jeffery C. Chancellor, Serena M. Auñon-Chancellor, John Charles

Faculty Publications

INTRODUCTION: Space radiation research has progressed rapidly in recent years, but there remain large uncertainties in predicting and extrapolating biological responses to humans. Exposure to cosmic radiation and solar particle events (SPEs) may pose a critical health risk to future spaceflight crews and can have a serious impact on all biomedical aspects of space exploration. The relatively minimal shielding of the cancelled 1960s Manned Orbiting Laboratory (MOL) program's space vehicle and the high inclination polar orbits would have left the crew susceptible to high exposures of cosmic radiation and high dose-rate SPEs that are mostly unpredictable in frequency and intensity. …

Cardiovascular disparities remain pervasive in the United States. Unequal disease burden is evident among population groups based on sex, race, ethnicity, socioeconomic status, educational attainment, nativity, or geography. Despite the significant declines in cardiovascular disease mortality rates in all demographic groups during the last 50 years, large disparities remain by sex, race, ethnicity, and geography. Recent data from modeling studies, linked micromap plots, and small-Area analyses also demonstrate prominent variation in cardiovascular disease mortality rates across states and counties, with an especially high disease burden in the southeastern United States and Appalachia. Despite these continued disparities, few large-scale intervention studies …

Recognizing The Danger Zone: Response Of Female White-Tailed To Discrete Hunting Events, Jeffery D. Sullivan, Stephen S. Ditchkoff, Bret A. Collier, Charles R. Ruth, Joshua B. Raglin

Faculty Publications

The landscape of fear theory proposes that prey should utilize habitat over space and time such that demographic risk is minimized. White-Tailed deer Odocoileus virginianus respond to temporally and spatially predictable threats posed by humans consistent with the landscape of fear theory. However, few studies examining the response of deer to hunting have accounted for the localized nature of risk. To determine if white-Tailed deer are able to recognize and respond to risks posed by hunters relative to specific hunting locations, we equipped 38 female white-Tailed deer with GPS collars August-December 2013-2015. Deer were generally found to increase use of …

Double-Crop Soybean Response To Potassium On Mid-Atlantic Coastal Plain And Piedmont Soils, Md Rasel Parvej, Anna S. Williams, David L. Holshouser, William H. Frame, Mark S. Reiter

Faculty Publications

Potassium fertilization research on soybean [Glycine max (L.) Merr.] double cropped with winter wheat (Triticum aestivum L.) is lacking. We characterized double-crop soybean response to fertilizer K across 22 Coastal Plain and Piedmont sites with and/or without wheat straw removal during 2013 to 2015. Mehlich-1 soil-K concentrations at 0- to 15- and 0- to 30-cm depths were better in explaining relative yield variability (r2 = 0.80), defining critical soil-K concentrations that ranged from 40 to 75 mg K kg–1 for 0- to 15-cm and 36 to 66 mg K kg–1 for 0- to 30-cm depths, and identifying K-deficient sites (100% …

Correlation And Calibration Of Soil-Test Potassium From Different Soil Depths For Full-Season Soybean On Coarse-Textured Soils, Anna S. Williams, Md Rasel Parvej, David L. Holshouser, William H. Frame, Mark S. Reiter

Faculty Publications

Quantifying soil-K availabilities at deeper depths may be necessary to determine optimum fertilizer-K rate for soybean [Glycine max (L.) Merr.] grown on low cation exchange capacity (CEC) soils that are prone to K leaching. We characterized full-season soybean response to fertilizer-K across 19 coarse-textured low- CEC sites during 2013 and 2014. Mehlich-1 soil-K concentrations at 0- to 15- and 0- to 30-cm depths better correlated with relative yield and explained 90% of relative yield variation compared to 77% for 0- to 60-cm depth. Critical soil-K concentrations were similar for relative yield, V5 plant-K concentration, and R2 leaf-K concentration, ranging from …

Investigating The Role Of Mitochondrial Respiratory Dysfunction During Hexavalent Chromium-Induced Lung Carcinogenesis, James T.F. Wise, Lei Wang, Michael C. Alstott, Ntube N.O. Ngalame, Yuting Wang, Zhuo Zhang, Xianglin Shi

Faculty Publications

Hexavalent chromium [Cr(VI)] is a lung carcinogen and its complete mechanism of action remains to be investigated. Metabolic reprogramming of key energy metabolism pathways (e.g., increased anaerobic glycolysis in the presence of oxygen or “Warburg effect,” dysregulated mitochondrial function, and lipogenesis) are important to cancer cell and tumor survival and growth. In our current understanding of Cr(VI)-induced carcinogenesis, the role for metabolic reprogramming remains unclear. In this study, we treated human lung epithelial cells (BEAS-2B) with Cr(VI) for 6 months and obtained malignantly transformed cells from an isolated colony grown in soft agar. We also used Cr(VI)-transformed cells from two …
