Research with the largest impact on practice and science is often conducted by teams with diverse substantive, clinical, and methodological expertise. Team and interdisciplinary research has created authorship groups with varied expertise and expectations. Co-authorship among team members presents many opportunities and challenges. Intentional planning, clear expectations, sensitivity to differing disciplinary perspectives, attention to power differentials, effective communication, timelines, attention to published guidelines, and documentation of progress will contribute to successful co-authorship. Both novice and seasoned authors will find the strategies identified by the Western Journal of Nursing Research Editorial Board useful for building positive co-authorship experiences.

Analysis Of Multiple Cytokine Polymorphisms In Individuals With Untreated Deep Carious Lesions Reveals Il1b (Rs1143643) As A Susceptibility Factor For Periapical Lesions Development, Alisa Dill, Ariadne Letra, Letıcia Chaves De Souza, Mamatha Yadlapati, Cláudia Cristina Biguetti, Gustavo P. Garlet, Alexandre R. Vieira, Renato Menezes Silva

School of Podiatric Medicine Publications

Introduction

It has been proposed that individual genetic predisposition may contribute to persistent apical periodontitis. Cytokines are associated with levels of inflammation and are involved in caries, pulpal, and periapical tissue destruction. We hypothesized that polymorphisms in cytokine genes may contribute to an individual’s increased susceptibility to apical tissue destruction in response to deep carious lesions.

Methods

Subjects with deep carious lesions, with or without periapical lesions (≥ 3 mm) were recruited at the University of Pittsburgh and the University of Texas at Houston. Genomic DNA samples of 316 patients were sorted into 2 groups: 136 cases with deep carious …

Preconception And Early Pregnancy Air Pollution Exposures And Risk Of Gestational Diabetes Mellitus, Candace Robledo, Pauline Mendola, Edwina H. Yeung, Tuija Männistö, Rajeshwari Sundaram, Danping Liu, Qi Ying, Seth Sherman, Katherine Grantz

School of Medicine Publications

Background: Air pollution has been linked to gestational diabetes mellitus (GDM) but no studies have evaluated impact of preconception and early pregnancy air pollution exposures on GDM risk.

Methods: Electronic medical records provided data on 219,952 singleton deliveries to mothers with (n=11,334) and without GDM (n=208,618). Average maternal exposures to particulate matter (PM) ≤ 2.5μm (PM2.5) and PM2.5 constituents, PM ≤ 10μm (PM10), nitrogen oxides (NOx), carbon monoxide, sulfur dioxide (SO2) and ozone (O3) were estimated for the 3-month preconception window, first trimester, and gestational weeks 1-24 based on modified Community Multiscale Air Quality models for delivery hospital referral regions. …

Proline Metabolism Increases Katg Expression And Oxidative Stress Resistance In Escherichia Coli, Lu Zhang, James R. Alfano, Donald F. Becker

Department of Biochemistry: Faculty Publications

The oxidation of L-proline to glutamate in Gram-negative bacteria is catalyzed by the proline utilization A (PutA) flavoenzyme, which contains proline dehydrogenase (PRODH) and _1-pyrroline-5-carboxylate (P5C) dehydrogenase domains in a single polypeptide. Previous studies have suggested that aside from providing energy, proline metabolism influences oxidative stress resistance in different organisms. To explore this potential role and the mechanism, we characterized the oxidative stress resistance of wild-type and putA mutant strains of Escherichia coli. Initial stress assays revealed that the putA mutant strain was significantly more sensitive to oxidative stress than the parental wild-type strain. Expression of PutA in the …

A Moonlighting Function Of Mycobacterium Smegmatis Ku In Zinc Homeostasis?, Ambuj K. Kushwaha, Dinesh K. Deochand, Anne Grove

Faculty Publications

© 2014 The Protein Society. Ku protein participates in DNA double-strand break repair via the nonhomologous end-joining pathway. The three-dimensional structure of eukaryotic Ku reveals a central core consisting of a β-barrel domain and pillar and bridge regions that combine to form a ring-like structure that encircles DNA. Homologs of Ku are encoded by a subset of bacterial species, and they are predicted to conserve this core domain. In addition, the bridge region of Ku from some bacteria is predicted from homology modeling and sequence analyses to contain a conventional HxxC and CxxC (where x is any residue) zinc-binding motif. …

Message from President: An ivy-league legend holds that early twentieth-century literary scholar George Lyman Kittredge once passed a doctoral student who had flubbed his dissertation defense when, upon asking the candidate about his smoking preferences, Kittredge discovered that the lad had a keen eye for quality cigars. Although we can thank our lucky stars that Kittredge’s kind of benevolent autocracy—his readiness to use unchecked authority to show off his combined power and tastefulness—is a thing of the past, we can also at least minimally mourn the passing of eccentricity and of the mix of moxie and eagerness that induces acts …

Genomic Variation In A Widespread Neotropical Bird (Xenops Minutus) Reveals Divergence, Population Expansion, And Gene Flow, Michael G. Harvey, Robb T. Brumfield

Faculty Publications

© 2014 Elsevier Inc. The demographic and phylogeographic histories of species provide insight into the processes responsible for generating biological diversity, and genomic datasets are now permitting the estimation of species histories with unprecedented accuracy. We used a genomic single nucleotide polymorphism (SNP) dataset generated using a RAD-Seq method to investigate the historical demography and phylogeography of a widespread lowland Neotropical bird (Xenops minutus). As expected, we found that prominent landscape features that act as dispersal barriers, such as Amazonian rivers and the Andes Mountains, are associated with the deepest phylogeographic breaks, and also that isolation by distance is limited …

Estimating The Production Function For Human Capital: Results From A Randomized Control Trial In Colombia, Orazio P. Attanasio, Sarah Cattan, Emla Fitzsimons, Costas Meghir, Marta Rubio-Codina

Cowles Foundation Discussion Papers

We examine the channels through which a randomized early childhood intervention in Colombia led to significant gains in cognitive and socio-emotional skills among a sample of disadvantaged children aged 12 to 24 months at baseline. We estimate the determinants of parents’ material and time investments in these children and evaluate the impact of the treatment on such investments. We then estimate the production functions for cognitive and socio-emotional skills. The effects of the program can be explained by increases in parental investments, emphasizing the importance of parenting interventions at an early age.

A New Species Of Telmatobius (Amphibia, Anura, Telmatobiidae) From The Pacific Slopes Of The Andes, Peru, Alessandro Catenazzi, Víctor Vargas García, Edgar Lehr

Publications

We describe a new species of Telmatobius from the Pacific slopes of the Andes in central Peru. Specimens were collected at 3900 m elevation near Huaytará, Huancavelica, in the upper drainage of the Pisco river. The new species has a snout–vent length of 52.5 ± 1.1 mm (49.3–55.7 mm, n = 6) in adult females, and 48.5 mm in the single adult male. The new species has bright yellow and orange coloration ventrally and is readily distinguished from all other central Peruvian Andean species of Telmatobius but T. intermedius by having vomerine teeth but lacking premaxillary and maxillary teeth, and …

Using The West Indian Manatee (Trichechus Manatus) As A Mechanism For Invasive Aquatic Plant Management In Florida, Aarin Conrad Allen, Edward O. Keith

Marine & Environmental Sciences Faculty Articles

West-Indian manatees (Trichechus manatus L.) are opportunistic, herbivorous aquatic mammals that occupy the warm, shallow coastal waters throughout the southeastern United States. Manatees are known to feed on large quantities of diverse plant types. Presently within the state of Florida, manatees are an endangered species facing environmental and anthropogenic threats. Several different organizations work to rescue and rehabilitate these animals for an eventual return to the wild. Also within Florida, invasive aquatic plants are becoming increasingly problematic, creating both negative economic and environmental impacts. Each year, efforts are made to control these exotic plant species through several different …

Simulation Modelling Of High-Throughput Cryopreservation Of Aquatic Germplasm: A Case Study Of Blue Catfish Sperm Processing, E. Hu, Thunshun Warren Liao, Terrence R. Tiersch

Faculty Publications

Emerging commercial-level technology for aquatic sperm cryopreservation has not been modelled by computer simulation. Commercially available software (ARENA, Rockwell Automation, Inc. Milwaukee, WI) was applied to simulate high-throughput sperm cryopreservation of blue catfish (Ictalurus furcatus) based on existing processing capabilities. The goal was to develop a simulation model suitable for production planning and decision making. The objectives were to: (1) predict the maximum output for 8-h workday; (2) analyse the bottlenecks within the process, and (3) estimate operational costs when run for daily maximum output. High-throughput cryopreservation was divided into six major steps modelled with time, resources, and logic structures. …

Ant Community Structure And Response To Disturbances On Coastal Dunes Of Gulf Of Mexico, Xuan Chen, Benjamin Adams, Cody Bergeron, Alexander Sabo, Linda Hooper-Bùi

Faculty Publications

Coastal dunes are complex and fragile ecosystems. The decrease in environmental stressors from sea to inland creates zonation patterns of habitats, which support high biodiversity. Although coastal dunes have been examined in primary succession studies for more than 100 years, invertebrates have received much less attention than other taxa. In this study, we examined ant community composition and its relationship with vegetation structure on dunes, and used ants as indicators to reveal the influence of anthropogenic disturbances on these habitats. Quadrat sampling, hand collecting, and beating plants were used to sample ants on coastal dunes fringing the northern Gulf of …

Aging is usually accompanied by a significant reduction in muscle mass and force. To determine the relative contribution of inactivity and aging per se to this decay, we compared muscle function and structure in (a) male participants belonging to a group of well-trained seniors (average of 70 years) who exercised regularly in their previous 30 years and (b) age-matched healthy sedentary seniors with (c) active young men (average of 27 years). The results collected show that relative to their sedentary cohorts, muscle from senior sportsmen have: (a) greater maximal isometric force and function, (b) better preserved fiber morphology and ultrastructure …

Perceptions Of Research Misconduct: Pilot Data From A National Survey, Anita M. Gordon, Helen Harton

Faculty Work

Studies have shown that serious misconduct in academic research (e.g., data fabrication) is uncommon, whereas questionable research practices (e.g., courtesy authorship) occur on a fairly regular basis (Fanelli, 2009; John, Lowenstein, & Prelec, 2012). Yet limited research has been undertaken to understand why researchers engage in these behaviors (Martinson, Anderson, Crain, & DeVries, 2006; Mumford, Connelly, Murphy, Devenport, Antes, Brown, et al., 2009), in spite of the critical attention that misconduct cases bring from scientists, policymakers, and the public. As in other areas of human endeavor, understanding the complex causes of misbehavior is critical in formulating appropriate prevention structures or …

Was There A Sensory Trade-Off In Primate Evolution? The Vomeronasal Groove As A Means Of Understanding The Vomeronasal System In The Fossil Record., Eva Christine Garrett

Dissertations, Theses, and Capstone Projects

Primates have remarkable visual adaptations compared to most other mammals, long explained as associated with a trade-off with olfaction (smell). However, as more information comes to light on the role of olfaction in primate behavior it becomes apparent that olfaction is not a trivial sense. Even humans use smell to communicate, albeit in subtle ways, and the olfactory systems of the lemurs and lorises are very well-developed. Olfaction, however, is actually comprised of two distinct systems - the main olfactory and vomeronasal systems. These two systems overlap in many functions, but the main olfactory system is considered fairly generalized while …

A Novel Scoring Based Distributed Protein Docking Application To Improve Enrichment, Prachi Pradeep, Craig Struble, Terrence Neumann, Daniel S. Sem, Stephen Merrill

Mathematics, Statistics and Computer Science Faculty Research and Publications

Molecular docking is a computational technique which predicts the binding energy and the preferred binding mode of a ligand to a protein target. Virtual screening is a tool which uses docking to investigate large chemical libraries to identify ligands that bind favorably to a protein target. We have developed a novel scoring based distributed protein docking application to improve enrichment in virtual screening. The application addresses the issue of time and cost of screening in contrast to conventional systematic parallel virtual screening methods in two ways. Firstly, it automates the process of creating and launching multiple independent dockings on a …

Activin-A And Bmp4 Levels Modulate Cell Type Specification During Chir-Induced Cardiomyogenesis, Min-Su Kim, Audrey Horst, Steven Blinka, Karl D. Stamm, Donna K. Mahnke, James Schuman, Rebekah Gundry, Aoy Tomita-Mitchell, John Lough

Mathematics, Statistics and Computer Science Faculty Research and Publications

The use of human pluripotent cell progeny for cardiac disease modeling, drug testing and therapeutics requires the ability to efficiently induce pluripotent cells into the cardiomyogenic lineage. Although direct activation of the Activin-A and/or Bmp pathways with growth factors yields context-dependent success, recent studies have shown that induction of Wnt signaling using low molecular weight molecules such as CHIR, which in turn induces the Activin-A and Bmp pathways, is widely effective. To further enhance the reproducibility of CHIR-induced cardiomyogenesis, and to ultimately promote myocyte maturation, we are using exogenous growth factors to optimize cardiomyogenic signaling downstream of CHIR induction. As …

What Happens When Species Move But Reserves Do Not? Creating Climate Adaptive Solutions To Climate Change, Nicholas Whipps

UC Law Journal

Most U.S. laws and regulations are not well-suited to respond to the effects of climate change, and the Endangered Species Act—the central federal law meant to protect threatened and endangered species at all costs—is no different. Conservation banking, an Endangered Species Act policy, is a market-based conservation strategy that incentivizes landowners to conserve species on their land. However, fee simple conservation strategies are ill-suited to protecting species on the move due to climate change. This Note first highlights the inadequacies of the current conservation banking system, then suggests how policy makers can transfer the market-based credit system used in conservation …

Pleiotropic Locus For Emotion Recognition And Amygdala Volume Identified Using Univariate And Bivariate Linkage, Emma E.M. Knowles, Reese Mckay, Jack W. Kent, Emma Sprooten, Melanie A. Carless, Joanne E. Curran, Marcio A. Almeida, Thomas D. Dyer, Harald H.H. Göring, Ravi Duggirala, John Blangero

School of Medicine Publications

Objective: The role of the amygdala in emotion recognition is well established, and amygdala volume and emotion recognition performance have each been shown separately to be highly heritable traits, but the potential role of common genetic influences on both traits has not been explored. The authors investigated the pleiotropic influences of amygdala volume and emotion recognition performance. Method: In a sample of randomly selected extended pedigrees (N=858), the authors used a combination of univariate and bivariate linkage to investigate pleiotropy between amygdala volume and emotion recognition performance and followed up with association analysis. Results: The authors found a pleiotropic region …

Machine Learning For Predicting Soil Classes In Three Semi-Arid Landscapes, Colby W. Brungard, Janis L. Boettinger, Michael C. Duniway, Skye A. Wills, Thomas C. Edwards Jr.

Plants, Soils, and Climate Faculty Publications

Mapping the spatial distribution of soil taxonomic classes is important for informing soil use and management decisions. Digital soil mapping (DSM) can quantitatively predict the spatial distribution of soil taxonomic classes. Key components of DSM are the method and the set of environmental covariates used to predict soil classes. Machine learning is a general term for a broad set of statistical modeling techniques. Many different machine learning models have been applied in the literature and there are different approaches for selecting covariates for DSM. However, there is little guidance as to which, if any, machine learning model and covariate set …

Repairing The Broken Market For Antibiotic Innovation, Kevin Outterson, John H. Powers, Gregory W. Daniel, Mark B. Mcclellan

Faculty Scholarship

Multidrug-resistant bacterial diseases pose serious and growing threats to human health. While innovation is important to all areas of health research, it is uniquely important in antibiotics. Resistance destroys the fruit of prior research, making it necessary to constantly innovate to avoid falling back into a pre-antibiotic era. But investment is declining in antibiotics, driven by competition from older antibiotics, the cost and uncertainty of the development process, and limited reimbursement incentives. Good public health practices curb inappropriate antibiotic use, making return on investment challenging in payment systems based on sales volume. We assess the impact of recent initiatives to …

An Exposure-Effect Approach For Evaluating Ecosystem-Wide Risks From Human Activities, Am Knights, Gj Piet, Rh Jongbloed, Et Al

School of Biological and Marine Sciences

Ecosystem-based management (EBM) is promoted as the solution for sustainable use. An ecosystem-wide assessment methodology is therefore required. In this paper, we present an approach to assess the risk to ecosystem components from human activities common to marine and coastal ecosystems. We build on: (i) a linkage framework that describes how human activities can impact the ecosystem through pressures, and (ii) a qualitative expert judgement assessment of impact chains describing the exposure and sensitivity of ecological components to those activities. Using case study examples applied at European regional sea scale, we evaluate the risk of an adverse ecological impact from …

Copper-Induced Intra-Specific Oxidative Damage And Antioxidant Responses In Strains Of The Brown Alga Ectocarpus Siliculosus With Different Pollution Histories, Ca Sáez, F Roncarati, A Moenne, Aj Moody, Mt Brown

School of Biological and Marine Sciences

Inter- and intra-specific variation in metal resistance has been observed in the ecologically and economically important marine brown macroalgae (Phaeophyceae), but the mechanisms of cellular tolerance are not well elucidated. To investigate inter-population responses of brown seaweeds to copper (Cu) pollution, the extent of oxidative damage and antioxidant responses were compared in three strains of the filamentous brown seaweed Ectocarpus siliculosus, the model organism for the algal class Phaeophyceae that diverged from other major eukaryotic groups over a billion year ago. Strains isolated from locations with different pollution histories (i.e. LIA, from a pristine site in Scotland; REP and Es524 …
