Differing Lectin Binding Profiles Among Human Embryonic Stem Cells And Derivatives Aid In The Isolation Of Neural Progenitor Cells, Mahesh C. Dodla, Amber Young, Alison Venable, Kowser Hasneen, Raj R. Rao, David W. Machacek, Steven L. Stice

Chemical and Life Science Engineering Publications

Human embryonic stem cells (hESCs) and their differentiated progeny allow for investigation of important changes/events during normal embryonic development. Currently most of the research is focused on proteinacous changes occurring as a result of differentiation of stem cells and little is known about changes in cell surface glycosylation patterns. Identification of cell lineage specific glycans can help in understanding their role in maintenance, proliferation and differentiation. Furthermore, these glycans can serve as markers for isolation of homogenous populations of cells. Using a panel of eight biotinylated lectins, the glycan expression of hESCs, hESCs-derived human neural progenitors (hNP) cells, and hESCs-derived …

Langevin Dynamics For The Transport Of Flexible Biological Macromolecules In Confined Geometries, Michael H. Peters

Chemical and Life Science Engineering Publications

The transport of flexible biological macromolecules in confined geometries is found in a variety of important biophysical systems including biomolecular movements through pores in cell walls, vesicle walls, and synthetic nanopores for sequencing methods. In this study, we extend our previous analysis of the Fokker–Planck and Langevin dynamics for describing the coupled translational and rotational motions of single structuredmacromolecules near structured external surfaces or walls [M. H. Peters, J. Chem. Phys. 110, 528 (1999); 112, 5488 (2000)] to the problem of many interacting macromolecules in the presence of structured external surfaces representing the confining geometry. Overall macromolecular flexibility …

A Model Based Feedback Controller For Wing-Twist Via Piezoceramic Actuation, John R. Singler, Belinda A. Batten

Mathematics and Statistics Faculty Research & Creative Works

In this paper we present a model for a rubber plate with piezoceramic actuators to represent a bioinspired flexible wing. Using a Galerkin based finite element approximation to the system, we compute a linear quadratic based tracking control for piezoelectric actuators placed along both leading and trailing edges. Using these piezoceramic devices, we demonstrate the effectiveness of model based feedback control in achieving a desired wing tip position; this modified shape is analogous to aircraft roll moment generation via wing twist.

Using The Timeline Followback To Identify Time Windows Representative Of Annual Posttreatment Drinking, Christopher J. Gioia

Theses and Dissertations

Using 12-month post treatment Timeline Followback drinking reports, data extrapolated from shorter time windows (e.g., 1 month, 6 months) were used to estimate total annual drinking. The objective was to determine whether data from a shorter time window would provide an estimate of annual drinking sufficiently consistent with the full year report such that it can be used in place of the full report. Data for this study were obtained from problem drinkers who voluntarily participated in a randomized controlled trial of a mail-based intervention. Complete follow-up data were obtained for 467 of the 825 participants who completed a 12-month …

Measurement Of Particle Size Distribution In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang

Faculty Publications

The majority of the research in animal buildings has been on measured concentrations of contaminants that the workers and animals are exposed to; emission measurements have only gained attention in recent years due to potential federal regulations on air quality emissions from animal feeding operations (AFOs). The contribution of AFOs to ambient PM10 and PM2.5 entails reliable measurement of particle size distribution. The objective of this study was to measure and compare the size distribution of particulate matter (PM) at multiple locations inside and at the exhausts of a wean‐to‐finish commercial swine building. The particle size distribution was measured by …

Spatial And Temporal Distributions Of Dust And Ammonia Concentrations In A Swine Building, Sheryll B. Jerez, Yuanhui Zhang, X Wang

Faculty Publications

Pollutants, especially dust, are rarely uniformly distributed within ventilated air spaces due to non‐uniform flow fields, particle inertia, gravitational settling, and diffusion. Thus, selecting suitable sampling locations for representative sampling is a challenge. The objective of this study was to determine the spatial and temporal distributions of dust and ammonia concentrations(NH3) in a swine building. Results of this study are useful in the design of sampling strategies that require limited sampling locations and in studying pollutant transport. This study was conducted in a commercial swine building in Illinois. The total suspended particulate (TSP) matter and ammonia concentrations were measured at …

Spread Of Plague Among Black-Tailed Prairie Dogs Is Associated With Colony Spatial Characteristics, Christopher Frey, Tammi L. Johnson, Jack Cully Jr., Sharon K. Collinge, Chris Ray, Brett Sandercock

Faculty Publications

Sylvatic plague (Yersinia pestis) is an exotic pathogen that is highly virulent in black-tailed prairie dogs (Cynomys ludovicianus) and causes widespread colony losses and individual mortality rates >95%. We investigated colony spatial characteristics that may influence inter-colony transmission of plague at 3 prairie dog colony complexes in the Great Plains. The 4 spatial characteristics we considered include: colony size, Euclidean distance to nearest neighboring colony, colony proximity index, and distance to nearest drainage (dispersal) corridor. We used multi-state mark–recapture models to determine the relationship between these colony characteristics and probability of plague transmission among prairie dog colonies. Annual mapping of …

Involving The Public In Restoring The Role Of Fire In The Longleaf Pine Ecosystem Of Upland Island Wilderness, Brian P. Oswald, Ike Mcwhorter, Penny Whisenant

Faculty Publications

The 13,250-acre Upland Island Wilderness (UIW) in Texas was established in 1984 and is managed by the United States Forest Service (USFS). Historically, portions of it consisted of open and diverse longleaf pine (Pinus palustris) ecosystems which depend on frequent, low-intensity surface fires. As in many other relatively small wilderness areas, the vegetation and fuel conditions in the UIW underwent extensive changes after wilderness designation. Lightning-caused wildfires were no longer allowed to burn with the frequency or intensity that characterized the natural fire regime. This has resulted in an increase of shade-tolerant trees and shrubs, heavy accumulations of …

Biosynthesis Of Hsaf, A Tetramic Acid-Containing Macrolactam From Lysobacter Enzymogenes, Lili Lou, Guoliang Qian, Yunxuan Xie, Jiliang Hang, Haotong Chen, Kathia Zaleta- Rivera, Yaoyao Li, Yuemao Shen, Patrick Dussault, Fengquan Liu, Liangcheng Du

Patrick Dussault Publications

HSAF was isolated from Lysobacter enzymogenes, a bacterium used in the biological control of fungal diseases of plants. Structurally, it is a tetramic acid-containing macrolactam fused to a tricyclic system. HSAF exhibits a novel mode of action by disrupting sphingolipids important to the polarized growth of filamentous fungi. Here, we described the HSAF biosynthetic gene cluster which contains only a single-module polyketide synthase-nonribosomal peptide synthetase (PKS/ NRPS), although the biosynthesis of HSAF apparently requires two separate polyketide chains that are linked together by one amino acid (ornithine) via two amide bonds. Flanking the PKS/ NRPS are six genes, encoding …

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Preeclampsia affects 3-8% of pregnancies and is a major cause of maternal and perinatal morbidity and mortality worldwide. This complex disorder is characterized by alterations in the immune and vascular systems and involves multiple organs. There is strong evidence for a genetic contribution to preeclampsia. Two different single nucleotide polymorphisms (SNPs) in the endoplasmic reticulum aminopeptidase 2 (ERAP2) gene were recently reported to be associated with increased risk for preeclampsia in two different populations. ERAP2 is expressed in placental tissue and it is involved in immune responses, inflammation, and blood pressure regulation; making it is an attractive preeclampsia …

Sheldon, Christopher C. Witt, Tamaki Yuri

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Microinversions are cytologically undetectable inversions of DNA sequences that accumulate slowly in genomes. Like many other rare genomic changes (RGCs), microinversions are thought to be virtually homoplasy-free evolutionary characters, suggesting that they may be very useful for difficult phylogenetic problems such as the avian tree of life. However, few detailed surveys of these genomic rearrangements have been conducted, making it difficult to assess this hypothesis or understand the impact of microinversions upon genome evolution.

Results

We surveyed non-coding sequence data from a recent avian phylogenetic study and found substantially more microinversions than expected based upon prior information about …

The Pax Gene Eyegone Facilitates Repression Of Eye Development In Tribolium, Nazanin Zarinkamar, Xiaoyun Yang, Riyue Bao, Frank Friedrich, Rolf Beutel, Markus Friedrich

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The Pax transcription factor gene eyegone (eyg) participates in many developmental processes in Drosophila, including the Notch signaling activated postembryonic growth of the eye primordium, global development of the adult head and the development of the antenna. In contrast to other Pax genes, the functional conservation of eyg in species other than Drosophila has not yet been explored.

Results

We investigated the role of eyg during the postembryonic development of the red flour beetle Tribolium castaneum. Our results indicate conserved roles in antennal but not in eye development. Besides segmentation defects in the antenna, Tribolium eyg knockdown animals …

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Significant numbers of people are exposed to tetrachloroethylene (perchloroethylene, PCE) every year, including workers in the dry cleaning industry. Adverse health effects have been associated with PCE exposure. However, investigations of possible cumulative cytogenetic damage resulting from PCE exposure are lacking.

Methods

Eighteen dry cleaning workers and 18 laundry workers (unexposed controls) provided a peripheral blood sample for cytogenetic analysis by whole chromosome painting. Pre-shift exhaled air on these same participants was collected and analyzed for PCE levels. The laundry workers were matched to the dry cleaners on race, age, and smoking status. The relationships between levels of …
