Waterpipe Smoking And Regulation In The United States: A Comprehensive Review Of The Literature, Linda Haddad, Omar El-Shahawy, Roula Ghadban, Tracey E. Barnett, Emily Johnson

Social and Behavioral Sciences Publications

Background: Researchers in tobacco control are concerned about the increasing prevalence of waterpipe smoking in the United States, which may pose similar risks as cigarette smoking. This review explores the prevalence of waterpipe smoking in the United States as well as the shortcomings of current U.S. policy for waterpipe control and regulation. Methods: Researchers conducted a literature review for waterpipe articles dated between 2004 and 2015 using five online databases: MEDLINE, CINHAHL, ScienceDirect, PMC, and Cochrane Library. Results: To date, few studies have explored the marketing and regulation of waterpipe smoking in the U.S., which has increased …

Upward Communication About Cancer Screening—Adolescent Daughter To Mother, Maghboeba Mosavel, Katie A. Ports

Social and Behavioral Sciences Publications

Substantial breast and cervical cancer disparities exist in the United States, particularly among African American women with low social economic status. There is considerable potential for discussions about cancer prevention between mothers and daughters. However, upward communication, from child to parent, remains a relatively novel research area, and it remains unclear how receptive mothers would be to messages from their daughter about cancer, a topic that may be considered culturally inappropriate for daughters to initiate. In this study, we simulated cancer message delivery to daughters and then conducted direct observation of daughters as they recalled and shared the message with …

The Importance Of Context: An Exploration Of Factors Influencing The Adoption Of Student-Centered Teaching Among Chemistry, Biology, And Physics Faculty, Travis J. Lund, Marilyne Stains

Department of Chemistry: Faculty Publications

Background: Research at the secondary and postsecondary levels has clearly demonstrated the critical role that individual and contextual characteristics play in instructors’ decision to adopt educational innovations. Although recent research has shed light on factors influencing the teaching practices of science, technology, engineering, and mathematics (STEM) faculty, it is still not well understood how unique departmental environments impact faculty adoption of evidence-based instructional practices (EBIPs) within the context of a single institution. In this study, we sought to characterize the communication channels utilized by STEM faculty, as well as the contextual and individual factors that influence the teaching practices …

Hfq Regulates Antibacterial Antibiotic Biosynthesis And Extracellular Lytic-Enzyme Production In Lysobacter Enzymogenes Oh11, Gaoge Xu, Yuxin Zhao, Liangcheng Du, Guoliang Qian, Fengquan Liu

Department of Chemistry: Faculty Publications

Lysobacter enzymogenes is an important biocontrol agent with the ability to produce a variety of lytic enzymes and novel antibiotics. Little is known about their regulatory mechanisms. Understanding these will be helpful for improving biocontrol of crop diseases and potential medical application. In the present study, we generated an hfq (encoding a putative ribonucleic acid chaperone) deletion mutant, and then utilized a new genomic marker-free method to construct an hfq-complemented strain. We showed for the first time that Hfq played a pleiotropic role in regulating the antibacterial antibiotic bio- synthesis and extracellular lytic enzyme activity in L. enzymogenes. Mutation of …

Limits And Perspectives For The Promotion Of The Inclusive Culture And Paradigm Within School Context: Theoretical Considerations And Empirical Findings From Greece And Hungary, Elias Kourkoutas, Agnes Nemethne Toth, Elena Vitalaki

Subsistence Strategies In Traditional Societies Distinguish Gut Microbiomes, Alexandra J. Obregon-Tito, Raul T. Tito, Jessica Metcalf, Krithvivasa Sankaranarayanan, Jose C. Clemente, Luke K. Ursell, Zhenjiang Zech Xu, Will Van Treuren, Rob Knight, Morris Foster

Division of Research and Economic Development Faculty & Staff Publications

Recent studies suggest that gut microbiomes of urban-industrialized societies are different from those of traditional peoples. Here we examine the relationship between lifeways and gut microbiota through taxonomic and functional potential characterization of faecal samples from hunter-gatherer and traditional agriculturalist communities in Peru and an urban-industrialized community from the US. We find that in addition to taxonomic and metabolic differences between urban and traditional lifestyles, hunter-gatherers form a distinct sub-group among traditional peoples. As observed in previous studies, we find that Treponema are characteristic of traditional gut microbiomes. Moreover, through genome reconstruction (2.2-2.5 MB, coverage depth x26-513) and functional potential …

Stepping Beyond Nuremberg’S Halo: The Legacy Of The Supreme National Tribunal Of Poland, Mark A. Drumbl

Scholarly Articles

The Supreme National Tribunal of Poland (Najwyzszy Trybunal Narodowy (Tribunal)) operated from 1946 to 1948. It implemented the 1943 Moscow Declaration in the case of suspected Nazi war criminals. This article unpacks two of the Tribunal’s trials, that of Rudolph Hoess (Kommandant of Auschwitz (Oswiecim) and Amon Goeth (commander of the Krakow-Plaszow labour camp). Following an introduction, the article proceeds in four sections. Section 2 sets out the Tribunal’s provenance and background, offering a flavour of the politics and pressures that contoured (and co-opted) its activities so as to recover its place within the imagined spaces of international criminal accountability. …

Resolving The Biophysics Of Axon Transmembrane Polarization In A Single Closed-Form Description, Robert Melendy

Faculty Publications - Department of Electrical Engineering and Computer Science

When a depolarizing event occurs across a cell membrane there is a remarkable change in its electrical properties. A complete depolarization event produces a considerably rapid increase in voltage that propagates longitudinally along the axon and is accompanied by changes in axial conductance. A dynamically changing magnetic field is associated with the passage of the action potential down the axon. Over 75 years of research has gone into the quantification of this phenomenon. To date, no unified model exist that resolves transmembrane polarization in a closed-form description. Here, a simple but formative description of propagated signaling phenomena in the membrane …

Biomechanics Of Head Impacts Associated With Diagnosed Concussion In Female Collegiate Ice Hockey Players, Bethany J. Wilcox, Jonathan G. Beckwith, Richard M. Greenwald, Neha P. Raukar, Jeffrey J. Chu, Thomas W. Mcallister, Laura A. Flashman, Arthur C. Maerlender, Ann-Christine Duhaime,, Joseph J. Crisco

Department of Psychology: Faculty Publications

Epidemiological evidence suggests that female athletes may be at a greater risk of concussion than their male counterparts. The purpose of this study was to examine the biomechanics of head impacts associated with diagnosed concussions in a cohort of female collegiate ice hockey players. Instrumented helmets were worn by 58 female ice hockey players from 2 NCAA programs over a three year period. Kinematic measures of single impacts associated with diagnosed concussion and head impact exposure on days with and without diagnosed concussion were evaluated. Nine concussions were diagnosed. Head impact exposure was greater in frequency and magnitude on days …

The Need For Theory To Guide Concussion Research, Dennis Molfese

Center for Brain, Biology, and Behavior: Faculty Publications

While the focus on concussion research has expanded greatly over the past decade, progress in identifying the mechanisms and consequences of head injury, the recovery path and the development of potential interventions to facilitate recovery have been largely absent. Instead, the field has largely progressed through an accumulation of data without the guidance of any systematic theory to guide the formulation of research questions or generate testable hypotheses. As part of this special issue on sports concussion, we advance a theory to describe the evolution of a neural network during the development of a cognitive process as well as the …

Programmed Physical Exertion In Recovery From Sports-Related Concussion: A Randomized Pilot Study, Arthur C. Maerlender, Wanda Rieman, Jonathan Lichtenstein, C. Condiracci

Department of Psychology: Faculty Publications

Although no data exist, general practice recommends only rest following concussion. This randomized clinical trial found that programmed physical exertion during recovery produced no significant differences in recovery time between groups of participants. However, high levels of exertion were deleterious. This study provides initial evidence that moderate physical activity is a safe replacement behavior during recovery.

Resting-State Brain Connectivity After Surgical And Behavioral Weight Loss, Rebecca J. Lepping, Amanda S. Bruce, Alex Francisco, Hung-Wen Yeh, Laura E. Martin, Joshua N. Powell, Laura Hancock, Trisha M. Patrician, Florence J. Breslin, Niazy Selim, Joseph E. Donnelly, William M. Brooks, Cary R. Savage, W. Kyle Simmons, Jared M. Bruce

Center for Brain, Biology, and Behavior: Faculty Publications

Objective: Changes in food-cue neural reactivity associated with behavioral and surgical weight loss interventions have been reported. Resting functional connectivity represents tonic neural activity that may contribute to weight loss success. This study explores whether intervention type is associated with differences in functional connectivity after weight loss. Methods: Fifteen participants with obesity were recruited prior to adjustable gastric banding surgery. Thirteen demographically matched participants with obesity were selected from a separate behavioral diet intervention. Resting-state functional magnetic resonance imaging was collected 3 months after surgery/ behavioral intervention. ANOVA was used to examine post-weight loss differences between the two groups in …

Toward Production Of Jet Fuel Functionality In Oilseeds: Identification Of Fatb Acyl-Acyl Carrier Protein Thioesterases And Evaluation Of Combinatorial Expression Strategies In Camelina Seeds, Hae Jin Kim, Jillian E. Silva, Hieu Sy Vu, Keithanne Mockaitis, Jeong-Won Nam, Edgar B. Cahoon

Center for Plant Science Innovation: Faculty Publications

Seeds of members of the genus Cuphea accumulate medium-chain fatty acids (MCFAs; 8:0–14:0). MCFA- and palmitic acid- (16:0) rich vegetable oils have received attention for jet fuel production, given their similarity in chain length to Jet A fuel hydrocarbons. Studies were conducted to test genes, including those from Cuphea, for their ability to confer jet fuel-type fatty acid accumulation in seed oil of the emerging biofuel crop Camelina sativa. Transcriptomes from Cuphea viscosissima and Cuphea pulcherrima developing seeds that accumulate >90% of C8 and C10 fatty acids revealed three FatB cDNAs (CpuFatB3, CvFatB1, and CpuFatB4 …

Fungal Morphogenesis, Xiaorong Lin, J. Andrew Alspaugh, Haoping Liu, Steven D. Harris

Center for Plant Science Innovation: Faculty Publications

Morphogenesis in fungi is often induced by extracellular factors and executed by fungal genetic factors. Cell surface changes and alterations of the microenvironment often accompany morphogenetic changes in fungi. In this review, we will first discuss the general traits of yeast and hyphal morphotypes and how morphogenesis affects development and adaptation by fungi to their native niches, including host niches. Then we will focus on the molecular machinery responsible for the two most fundamental growth forms, yeast and hyphae. Last, we will describe how fungi incorporate exogenous environmental and host signals together with genetic factors to determine their morphotype and …

Gene Silencing In Microalgae: Mechanisms And Biological Roles, Eun-Jeong Kim, Xinrong Ma, Heriberto Cerutti

Center for Plant Science Innovation: Faculty Publications

Microalgae exhibit enormous diversity and can potentially contribute to the production of biofuels and high value compounds. However, for most species, our knowledge of their physiology, metabolism, and gene regulation is fairly limited. In eukaryotes, gene silencing mechanisms play important roles in both the reversible repression of genes that are required only in certain contexts and the suppression of genome invaders such at transposons. The recent sequencing of several algal genomes is providing insights into the complexity of these mechanisms in microalgae. Collectively, glaucophyte, red, and green microalgae contain the machineries involved in repressive histone H3 lysine methylation, DNA cytosine …

Sirna-Directed Dna Methylation In Plants, Meng Xie, Bin Yu

Center for Plant Science Innovation: Faculty Publications

DNA cytosine methylationis an important epigenetic process that is correlated with transgene silencing, transposon suppression, and gene imprinting. In plants, small interfering RNAs (siRNAs) can trigger DNA methylation at loci containing their homolog sequences through a process called RNAdirected DNA methylation (RdDM). In canonical RdDM, 24 nucleotide (nt) siRNAs (ra-siRNAs) will be loaded into their effector protein called ARGONAUTE 4 (AGO4) and subsequently targeted to RdDM loci through base-pairing with the non-coding transcripts produced by DNA-directed RNA Polymerase V. Then, the AGO4-ra-siRNA will recruit the DNA methyltransferase to catalyze de novo DNA methylation. Recent studies also identified non-canonical RdDM pathways …

The Role Of Ethylene In Plant Responses To K+ Deficiency, Daniel P. Schachtman

Center for Plant Science Innovation: Faculty Publications

Potassium is an essential macronutrient that is involved in regulating turgor , in driving plant growth, and in modulating enzyme activation. The changes in root morphology, root function, as well as cellular and molecular responses to low potassium conditions have been studied in the model plant Arabidopsis and in other plant species. In Arabidopsis ethylene plays a key role in roots in the transduction of the low potassium signal, which results in altered root function and growth. The first clues regarding the role of ethylene were detected through transcriptional profiling experiments showing changes in the expression of genes related to …

Redirection Of Metabolic Flux For High Levels Of Omega-7 Monounsaturated Fatty Acid Accumulation In Camelina Seeds, Huu Tam Nguyen, Hyunwoo Park, Karen L. Koster, Rebecca E. Cahoon, Hanh Nguyen, John Shanklin, Thomas E. Clemente, Edgar B. Cahoon

Center for Plant Science Innovation: Faculty Publications

Seed oils enriched in omega-7 monounsaturated fatty acids, including palmitoleic acid (16:1Δ9) and cis-vaccenic acid (18:1Δ11), have nutraceutical and industrial value for polyethylene production and biofuels. Existing oilseed crops accumulate only small amounts (<2%) of these novel fatty acids in their seed oils. We demonstrate a strategy for enhanced production of omega-7 monounsaturated fatty acids in camelina (Camelina sativa) and soybean (Glycine max) that is dependent on redirection of metabolic flux from the typical Δ9 desaturation of stearoyl (18:0)-acyl carrier protein (ACP) to Δ9 desaturation of palmitoyl (16:0)-acyl carrier protein (ACP) and coenzyme A (CoA). This was achieved by seed-specific co-expression of a mutant Δ9-acyl-ACP and an acyl-CoA desaturase with high specificity for 16:0-ACP and CoA substrates, respectively. This strategy was most effective in camelina where seed oils with ~17% omega-7 monounsaturated fatty acids were obtained.

Further increases in omega-7 fatty acid accumulation to 60–65% of the total fatty acids in camelina seeds were achieved by inclusion of seed-specific suppression of 3-keto-acyl-ACP synthase II and the FatB 16:0-ACP thioesterase genes to increase substrate pool sizes of 16:0-ACP for the Δ9-acyl-ACP desaturase and by blocking C18 fatty acid elongation. Seeds from these lines also had total saturated fatty acids reduced to ~5% of …

Production Of High Levels Of Poly-3-Hydroxybutyrate In Plastids Of Camelina Sativa Seeds, Meghna R. Malik, Wenyu Tang, Nii Patterson, Jihong Tang, Rachel L. Wellinghoff, Mary L. Preuss, Claire Burkitt, Nirmala Sharma, Yuanyuan Ji, Joseph M. Jez, Oliver P. Peoples, Jan G. Jaworski, Edgar B. Cahoon, Kristi D. Snell

Center for Plant Science Innovation: Faculty Publications

Poly-3-hydroxybutyrate (PHB) production in plastids of Camelina sativa seeds was investigated by comparing levels of polymer produced upon transformation of plants with five different binary vectors containing combinations of five seed-specific promoters for expression of transgenes. Genes encoding PHB biosynthetic enzymes were modified at the N-terminus to encode a plastid targeting signal. PHB levels of up to 15% of the mature seed weight were measured in single sacrificed T1 seeds with a genetic construct containing the oleosin and glycinin promoters.

A more detailed analysis of the PHB production potential of two of the best performing binary vectors in a Camelina …

Leveraging Library Ecology: Growing Beyond Boundaries To Cultivate A Sustainable Knowledge Community Through Team-Based Librarianship, Ellen R. Urton, Meagan J. Duever, Casey D. Hoeve, Jenny K. Oleen, David Vail

University of Nebraska-Lincoln Libraries: Faculty Publications

Higher education increasingly challenges libraries to thrive while adapting to fiscal realities, imploring institutions to accomplish more with less, and leverage assets creatively. When competing demands vie for attention, interdisciplinary concepts such as sustainability may be neglected, or simply absent from a library’s mission. A team-based community of librarians can galvanize existing assets wherever they reside within an organization. This approach requires that librarians transcend traditional boundaries to reveal untapped or underutilized expertise. Interdepartmental teams within a library can address topics difficult to assign to one designated specialist, and access the education, interests, or networks possessed by multiple individuals across …

Variable Frequency Of Plastid Rna Editing Among Ferns And Repeated Loss Of Uridine-To-Cytidine Editing From Vascular Plants, Wenhu Guo, Felix Grewe, Jeffrey P. Mower

Center for Plant Science Innovation: Faculty Publications

The distinct distribution and abundance of C-to-U and U-to-C RNA editing among land plants suggest that these two processes originated and evolve independently, but the paucity of information from several key lineages limits our understanding of their evolution. To examine the evolutionary diversity of RNA editing among ferns, we sequenced the plastid transcriptomes from two early diverging species, Ophioglossum californicum and Psilotum nudum. Using a relaxed automated approach to minimize false negatives combined with manual inspection to eliminate false positives, we identified 297 C-to-U and three U-to-C edit sites in the O. californicum plastid transcriptome but only 27 C-to-U …

Microrna Biogenesis, Degradation And Activity In Plants, Meng Xie, Shuxin Zhang, Bin Yu

Center for Plant Science Innovation: Faculty Publications

microRNAs (miRNAs) are important regulators of gene expression. After excised from primary miRNA transcript by dicer-like1 (DCL1, an RNAse III enzyme), miRNAs bind and guide their effector protein named argonaute 1 (AGO1) to silence the expression of target RNAs containing their complementary sequences in plants. miRNA levels and activities are tightly controlled to ensure their functions in various biological processes such as development, metabolism and responses to abiotic and biotic stresses. Studies have identified many factors that involve in miRNA accumulation and activities. Characterization of these factors in turn greatly improves our understanding of the processes related to miRNAs. Here, …
