Frontiers in Public Health Services and Systems Research

Introduction: This practice-based research study capitalized on the statewide implementation of a comprehensive, locally-driven initiative to implement evidence-based policy, system and environmental changes related to obesity and tobacco use. The study examined local health department (LHD) performance and factors such as organizational quality improvement (QI) maturity, structure and governance.

Methods: State health department staff reviewed grant reports and documentation pertaining to all LHD grantees, which collectively represented all 87 counties and 4 cities in Minnesota (MN), in order to designate grantees as either: “Exceeds Expectations,” “Meets Expectations” or “Approaching Expectations.” A study team of state, local and academic partners then …

The Effect Of Household Financial, Time And Environmental Constraints On Very Low Food Security Among Children, Helen H. Jensen, Oleksandr Zhylyevskyy

University of Kentucky Center for Poverty Research Discussion Paper Series

Food insecurity is detrimental to children’s well-being. A better understanding of factors contributing to low and very low food security among children in the United States can guide the design of food assistance programs. We analyze the effects of household characteristics and local food environment attributes, including food prices and availability of food stores and eating places, on children’s food insecurity. We also investigate the effects of these characteristics and attributes on food preparation time. Using Becker’s household production approach, we propose an economic model that formalizes the use of constrained financial and time resources in the household. The model …

Autophagy Is Involved In Oligodendroglial Precursor-Mediated Clearance Of Amyloid Peptide, Wenxia Li, Yifen Tang, Zhiqin Fan, Ya Meng, Guang Yang, Jia Luo, Zun-Ji Ke

Internal Medicine Faculty Publications

BACKGROUND: Accumulation of β-amyloid peptides is an important hallmark of Alzheimer's disease (AD). Tremendous efforts have been directed to elucidate the mechanisms of β-amyloid peptides degradation and develop strategies to remove β-amyloid accumulation. In this study, we demonstrated that a subpopulation of oligodendroglial precursor cells, also called NG2 cells, were a new cell type that can clear β-amyloid peptides in the AD transgene mice and in NG2 cell line.

RESULTS: NG2 cells were recruited and clustered around the amyloid plaque in the APPswe/PS1dE9 mice, which is Alzheimer's disease mouse model. In vitro, NG2 cell line and primary NG2 cells engulfed …

Population Cancer Risks Associated With Coal Mining: A Systematic Review, Wiley D. Jenkins, W. Jay Christian, Georgia Mueller, K. Thomas Robbins

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this regard.

METHODS: We performed a systematic review of English-language manuscripts published since 1980 to determine if coal mining exposure was associated with increased cancer risk (incidence and mortality).

RESULTS: Of 34 studies identified, 27 studied coal mining as an occupational exposure …

The Use Of Co-Culturing In Solid Substrate Cultivation And Possible Solutions To Scientific Challenges, Wanying Yao, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

This perspective systematically summarizes the use of solid substrate co‐cultures in agriculture, food, plant, and industrial biotechnology applications. The summarization is organized by organism, i.e. fungus, bacteria, yeast and then co‐cultivation of either two or three organisms. Generally, in solid substrate co‐culture, the organisms synergistically penetrate and degrade the solid substrate, thereby increasing product yield and productivity over a monoculture. Efforts to increase co‐culture performance include optimizing process parameters (pH, temperature, moisture, and oxygen demand) and defining the acceptable types of substrate. Scientific challenges exist in understanding the interactions between microbial stains, such as viability, suite of products, and bio‐transformations. …

The priorities that emerge are framed in the following way: (1) opportunities for increased and more targeted research to help …

Does It Have To Taste Bad To Be Good? Leveraging Pleasure To Enhance Learning, Karen H. Dougherty M.D.

Kentucky Journal of Higher Education Policy and Practice

Emerging information from the field of neuroscience has illuminated the workings of the brain’s pleasure circuit as a powerful motivator of human behavior. While much of the research has been driven by an effort to uncover the roots of addiction, an understanding of the aspects of pleasure can be applied to the design of teaching strategies to engage college students and improve their retention and persistence.

Voluntary Exercise Protects Against Methamphetamine-Induced Oxidative Stress In Brain Microvasculature And Disruption Of The Blood--Brain Barrier, Michal Toborek, Melissa J. Seelbach, Cetewayo S. Rashid, Ibolya E. András, Lei Chen, Minseon Park, Karyn A. Esser

Physiology Faculty Publications

BACKGROUND: There is no effective therapeutic intervention developed targeting cerebrovascular toxicity of drugs of abuse, including methamphetamine (METH). We hypothesize that exercise protects against METH-induced disruption of the blood--brain barrier (BBB) by enhancing the antioxidant capacity of cerebral microvessels and modulating caveolae-associated signaling. Mice were subjected to voluntary wheel running for 5 weeks resembling the voluntary pattern of human exercise, followed by injection with METH (10 mg/kg). The frequency, duration, and intensity of each running session were monitored for each mouse via a direct data link to a computer and the running data are analyzed by Clock labTM Analysis software. …

Health inequalities, which have been well documented for decades, have recently become policy targets in the United States. This report summarizes current patterns and trends in health inequalities, commitments to reduce health inequalities, and progress made to eliminate health inequalities. Time trend data indicate improvements in health status and major risk factors but increases in morbidity, with black and lower-education individuals experiencing a disproportionate burden of disease. A common policy response has been priority setting in the form of national objectives or goals to address health inequalities. More research and better methods are needed to precisely measure relationships between stated …

Influence Of Media Composition On The Growth Rate Of Chlorella Vulgaris And Scenedesmus Acutus Utilized For Co2 Mitigation, Czarena L. Crofcheck, Xinyi E, Aubrey Shea, Michael D. Montross, Mark Crocker, Rodney Andrews

Biosystems and Agricultural Engineering Faculty Publications

Atmospheric carbon dioxide levels have increased since the industrial revolution due to increasing combustion of fossil fuels. One possible CO₂ mitigation strategy is the use of microalgae for mitigation of CO₂. This paper focuses on the influence of media composition on the growth rate of two microalgae strains, Chlorella vulgaris and Scenedesmus actus. A KNO₃ based medium was found to work better for Chlorella, while a urea based equivalent worked better for Scenedesmus. The urea based media investigated here resulted in growth similar to that found with previously reported KNO₃ based media. …

Nelson, Hae-Yun Chung, Wolfgang Schalch, Jonas Wittwer, Leonard W. Poon

Sanders-Brown Center on Aging Faculty Publications

Oxidative stress is involved in age-related cognitive decline. The dietary antioxidants, carotenoids, tocopherols, and vitamin A may play a role in the prevention or delay in cognitive decline. In this study, sera were obtained from 78 octogenarians and 220 centenarians from the Georgia Centenarian Study. Brain tissues were obtained from 47 centenarian decedents. Samples were analyzed for carotenoids, α-tocopherol, and retinol using HPLC. Analyte concentrations were compared with cognitive tests designed to evaluate global cognition, dementia, depression and cognitive domains (memory, processing speed, attention, and executive functioning). Serum lutein, zeaxanthin, and β-carotene concentrations were most consistently related to better cognition …

Juvenile Hormone And Insulin Regulate Trehalose Homeostasis In The Red Flour Beetle, Tribolium Castaneum, Jingjing Xu, Zhentao Sheng, Subba R. Palli

Entomology Faculty Publications

Insulin/IGF-1 signaling (IIS) has been well studied for its role in the control of life span extension and resistance to a variety of stresses. The Drosophila melanogaster insulin-like receptor (InR) mutant showed extended life span due to reduced juvenile hormone (JH) levels. However, little is known about the mechanism of cross talk between IIS and JH in regulation of life span extension and resistance to starvation. In the current study, we investigated the role of IIS and JH signaling in regulation of resistance to starvation. Reduction in JH biosynthesis, JH action, or insulin-like peptide 2 (ILP2) syntheses by RNA interference …

Green Tea Polyphenols And Sulfasalazine Have Parallel Anti-Inflammatory Properties In Colitis Models, Helieh S. Oz, Theresa Chen, Willem J.S. De Villiers

Internal Medicine Faculty Publications

Background: There is no cure for autoimmune chronic inflammatory bowel disease (IBD). IBD patients commonly use complementary and alternative medications of which the safety, efficacy, and interaction with standard-of-care therapies are not fully known. Thus the consequences can become life-threatening. Sulfasalazine commonly used in IBD, potentially has severe adverse effects, including infertility, pulmonary fibrosis, lack of response, and ultimately patients may require intestinal resection. We hypothesized that green tea polyphenols (GrTP, EGCG) and sulfasalazine have similar anti-inflammatory properties.

Methods: BALB/c mice received Dextran sodium sulfate (DSS) to induce colitis (ulcerative colitis model). Exposure of IL-10 deficient mice (BALB/c-background) to normal …

Does Naloxone Reinstate Secondary Hyperalgesia In Humans After Resolution Of A Burn Injury? A Placebo-Controlled, Double-Blind, Randomized, Cross-Over Study, Manuel P. Pereira, Mads U. Werner, Thomas K. Ringsted, Michael C. Rowbotham, Bradley K. Taylor, Joergen B. Dahl

Physiology Faculty Publications

INTRODUCTION: Development of secondary hyperalgesia following a cutaneous injury is a centrally mediated, robust phenomenon. The pathophysiological role of endogenous opioid signalling to the development of hyperalgesia is unclear. Recent animal studies, carried out after the resolution of inflammatory pain, have demonstrated reinstatement of tactile hypersensitivity following administration of μ-opioid-receptor-antagonists. In the present study in humans, we analyzed the effect of naloxone when given after the resolution of secondary hyperalgesia following a first-degree burn injury.

METHODS: Twenty-two healthy volunteers were included in this placebo-controlled, randomized, double-blind, cross-over study. Following baseline assessment of thermal and mechanical thresholds, a first-degree burn injury …

Tlr4 Signaling Is Involved In Brain Vascular Toxicity Of Pcb153 Bound To Nanoparticles, Bei Zhang, Jeong June Choi, Sung Yong Eum, Sylvia Daunert, Michal Toborek

Graduate Center for Nutritional Sciences Faculty Publications

PCBs bind to environmental particles; however, potential toxicity exhibited by such complexes is not well understood. The aim of the present study is to study the hypothesis that assembling onto nanoparticles can influence the PCB153-induced brain endothelial toxicity via interaction with the toll-like receptor 4 (TLR4). To address this hypothesis, TLR4-deficient and wild type control mice (males, 10 week old) were exposed to PCB153 (5 ng/g body weight) bound to chemically inert silica nanoparticles (PCB153-NPs), PCB153 alone, silica nanoparticles (NPs; diameter, 20 nm), or vehicle. Selected animals were also subjected to 40 min ischemia, followed by a 24 h reperfusion. …

Differential Undertaking Response Of A Lower Termite To Congeneric And Conspecific Corpses, Qian Sun, Kenneth F. Haynes, Xuguo Zhou

Entomology Faculty Publications

Undertaking behaviour is an essential activity in social insects. Corpses are often recognized by a postmortem change in a chemical signature. Reticulitermes flavipes responded to corpses within minutes of death. This undertaking behaviour did not change with longer postmortem time (24 h); however, R. flavipes exhibited distinctively different behaviours toward dead termites from various origins. Corpses of the congeneric species, Reticulitermes virginicus, were buried onsite by workers with a large group of soldiers guarding the burial site due to the risk of interspecific competition; while dead conspecifics, regardless of colony origin, were pulled back into the holding chamber for nutrient …

The Endosymbiont Arsenophonus Is Widespread In Soybean Aphid, Aphis Glycines, But Does Not Provide Protection From Parasitoids Or A Fungal Pathogen, Jason A. Wulff, Karrie A. Buckman, Kongming Wu, George E. Heimpel, Jennifer A. White

Entomology Faculty Publications

Aphids commonly harbor bacterial facultative symbionts that have a variety of effects upon their aphid hosts, including defense against hymenopteran parasitoids and fungal pathogens. The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), is infected with the symbiont Arsenophonus sp., which has an unknown role in its aphid host. Our research goals were to document the infection frequency and diversity of the symbiont in field-collected soybean aphids, and to determine whether Arsenophonus is defending soybean aphid against natural enemies. We performed diagnostic PCR and sequenced four Arsenophonus genes in soybean aphids from their native and introduced range to estimate infection frequency …

Nutrition Intervention To Decrease Symptoms In Patients With Advanced Heart Failure, Terry A. Lennie, Debra K. Moser, Martha J. Biddle, Darlene Welsh, Geza G. Bruckner, D. Travis Thomas, Mary Kay Rayens, Alison L. Bailey

Nursing Faculty Publications

For a majority of patients with advanced heart failure, there is a need for complementary, non-pharmacologic interventions that could be easily implemented by health care providers to provide palliative care. Three major pathologic pathways underlying heart failure symptoms have been identified: fluid overload, inflammation, and oxidative stress. Prior research has demonstrated that three nutrients-sodium, omega-3 fatty acids, and lycopene-can alter these pathologic pathways. Therefore, the purposes of this study are to test the effects of a 6-month nutrition intervention of dietary sodium reduction combined with supplementation of lycopene and omega-3 fatty acids on heart failure symptoms, health-related quality of life, …

Rediscovering The Core Of Public Health, Steven Teutsch, Jonathan E. Fielding

Frontiers in Public Health Services and Systems Research

The success of public health has been its ability to understand contemporary health problems, to communicate the needs successfully, to identify solutions, and to implement them through programs and policies. In the past 50 years, those successes can be attributed largely to control of infectious disease, improved maternal and child health, delivery of other personal health care services, and changes in behaviors, particularly smoking. Yet health is primarily a product of our social, cultural, and physical environments. To continue to improve the nation’s health and reduce disparities, public health needs to return to its historical roots and engage with other …

Corpse Management In Social Insects, Qian Sun, Xuguo Zhou

Entomology Faculty Publications

Undertaking behavior is an essential adaptation to social life that is critical for colony hygiene in enclosed nests. Social insects dispose of dead individuals in various fashions to prevent further contact between corpses and living members in a colony. Focusing on three groups of eusocial insects (bees, ants, and termites) in two phylogenetically distant orders (Hymenoptera and Isoptera), we review mechanisms of death recognition, convergent and divergent behavioral responses toward dead individuals, and undertaking task allocation from the perspective of division of labor. Distinctly different solutions (e.g., corpse removal, burial and cannibalism) have evolved, independently, in the holometabolous hymenopterans and …

Effects Of Aging On Apoptosis Gene Expression In Oral Mucosal Tissues, Octavio A. Gonzalez, Michael John Novak, Sreenatha S. Kirakodu, Arnold J. Stromberg, Shu Shen, Luis Orraca, Janis Gonzalez-Martinez, Jeffrey L. Ebersole

Center for Oral Health Research Faculty Publications

Apoptotic processes are important for physiologic renewal of an intact epithelial barrier and contribute some antimicrobial resistance for bacteria and viruses, as well as anti-inflammatory effects that benefits the mucosa. The oral cavity presents a model of host-bacterial interactions at mucosal surfaces, in which a panoply of microorganisms colonizes various niches in the oral cavity and creates complex multispecies biofilms that challenge the gingival tissues. This report details gene expression in apoptotic pathways that occur in oral mucosal tissues across the lifespan, using a nonhuman primate model. Macaca mulatta primates from 2 to 23 years of age (n = …

Population Impacts Of Wolbachia On Aedes Albopictus, James W. Mains, Corey L. Brelsfoard, Philip R. Crain, Yunxin Huang, Stephen L. Dobson

Entomology Faculty Publications

Prior studies have demonstrated that Wolbachia, a commonly occurring bacterium capable of manipulating host reproduction, can affect life history traits in insect hosts, which in turn can have population-level effects. Effects on hosts at the individual level are predicted to impact population dynamics, but the latter has not been examined empirically. Here, we describe a biological model system based on Aedes albopictus (Asian tiger mosquito) that allows for measurement of population dynamics, which has not been accomplished in prior field trials or laboratory designs. The results demonstrate the studied populations to be robust and allow for persistent, closed populations with …
