Abcb6 Is A Porphyrin Transporter With A Novel Trafficking Signal That Is Conserved In Other Abc Transporters, Yu Fukuda

Theses and Dissertations (ETD)

The ATP-binding cassette (ABC) transporters play an important role as a barrier to protect cells from the accumulation of toxic xenobiotics and metabolites due to their ability to translocate a wide array of compounds across lipid bilayers. However, many ABC transporters, especially the ones localized in the intracellular organelles, are involved in critical biological processes such as antigen presentation. The core unit of ABC transporters contains two functional domains: the membrane spanning domain (MSD) and the nucleotide binding domain. The full transporters contain two of these units in tandem in a single polypeptide, whereas the half transporters only contain one …

Reconstructing Three-Dimensional Shape Envelopes From Time-Resolved Small-Angle X-Ray Scattering Data, Jessica Lamb, Lisa W. Kwok, Xiangyun Qiu, Kurt Andresen, Hye Yoon Park, Lois Pollack

Physics and Astronomy Faculty Publications

Modern computing power has made it possible to reconstruct low-resolution, three-dimensional shapes from solution small-angle X-ray scattering (SAXS) data on biomolecules without a priori knowledge of the structure. In conjunction with rapid mixing techniques, SAXS has been applied to time resolve conformational changes accompanying important biological processes, such as biomolecular folding. In response to the widespread interest in SAXS reconstructions, their value in conjunction with such time-resolved data has been examined. The group I intron from Tetrahymena thermophila and its P4–P6 subdomain are ideal model systems for investigation owing to extensive previous studies, including crystal structures. The goal of this …

Imaging Activity Of Neuronal Populations With New Long-Wavelength Voltage-Sensitive Dyes, Joseph P. Wuskell, Leslie M. Loew

UCHC Articles - Research

We have assessed the utility of five new long-wavelength fluorescent voltage-sensitive dyes (VSD) for imaging the activity of populations of neurons in mouse brain slices. Although all the five were capable of detecting activity resulting from activation of the Schaffer collateral-CA1 pyramidal cell synapse, they differed significantly in their properties, most notably in the signal-to-noise ratio of the changes in dye fluorescence associated with neuronal activity. Two of these dyes, Di-2-ANBDQPQ and Di-1-APEFEQPQ, should prove particularly useful for imaging activity in brain tissue and for combining VSD imaging with the control of neuronal activity via light-activated proteins such as channelrhodopsin-2 …

Isotopic Evidence Of Methane Oxidation Across The Surface Water–Ground Water Interface, Diego Andrés Riveros-Iregui, Jennifer Y. King

School of Natural Resources: Faculty Publications

Biogenic methane (CH₄) from wetlands plays a crucial role in the carbon cycle, but the dynamics of dissolved methane flux across the surface water-ground water interface remain poorly understood. This study focused on the effects of spatial transformation of dissolved methane and the role of ground-water recharge in the distribution of dissolved methane across the surface water-ground water interface. Here we present carbon isotopic measurements of biogenic methane and dissolved inorganic carbon (DIC) from the Sarita Wetland, on the St. Paul Campus of the University of Minnesota, and also in six monitoring wells located down gradient from the …

Diagnosing Death: Why Does It Remain "Well Settled And Persistently Unresolved"?, Melissa M. Goldstein

Health Policy and Management Faculty Publications

For ten days after Motl Brody had been declared dead by physicians, the 12-year-old boy lay in an intensive-care unit of Children's National Medical Center, sustained by drugs and a ventilator. His Orthodox Jewish parents insisted that, according to religious law, Motl remained alive because his heart continued to beat. District of Columbia law said he did not.

Although statutes on the books of every U.S. state allow a determination of death when all functions of the brain, including the brain stem, have irreversibly ceased, there is continued debate, especially in religious, philosophical, and bioethics contexts, about how, or even …

Lidar-Derived Benthic Habitat Maps Enable The Quantification Of Potential Dredging Impacts To Coral Reef Ecosystems, Brian K. Walker, Richard E. Dodge, David S. Gilliam

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

An essential component to the analysis of ecosystem services is to characterize and define the major habitats within the area of interest. Aerial photography and/or satellite imagery coupled with geographic information systems (GIS) are frequently used to identify and quantify habitats in open terrestrial ecosystems. However, it is more difficult to successfully apply this methodology to deeper, <20 m, underwater environments. Light detection and ranging (LIDAR), a relatively new remote sensing technology that provides detailed bathymetry, can be used when adequate imagery is not available. This study uses LIDAR as the basis to characterize various benthic habitats in a coral reef ecosystem in order to quantify the habitats for a Habitat Equivalency Analysis (HEA) related to planned dredging activities to expand the Port Everglades entrance channel, Broward County, FL. As part of a regional mapping effort, marine benthic habitats were characterized for Broward County, FL. A mosaic of interpolated, sunshaded, laser bathymetry data served as the foundation upon which acoustic ground discrimination, limited subbottom profiling and aerial photography, and groundtruthing data were added in a GIS to aid in interpretation of benthic habitats. Expert-driven visual interpretation outlined geomorphological features in the LIDAR data at a scale of 1:6000 with a minimum mapping unit of 1 acre. The map of Broward County yielded a high overall accuracy of 89.6%. To quantify the potential dredging impacts, the habitat layer was clipped in GIS to the boundaries of anticipated direct and indirect impacts of the proposed project. Then the area of each clipped polygon was totaled for each habitat by impact type. HEA and Florida’s Uniform Mitigation Assessment Method (UMAM) were performed using these areas. This work would not have been possible using satellite imagery or aerial photography alone and illustrates the capability of relatively new remote sensing technologies to aid in the definition and quantification of habitats for ecosystem service analyses.

Leadership For Today Effective Decision Making Strategies For Groups, Karla Trautman

SDSU Extension Extra Archives

Have you ever been faced with making a difficult decision? If so, you were likely challenged to discover facts, balance emotions, and take into account the conse¬quences that the resulting action will have on others. In other words, decision making is hard work! Decision making is also not an easy process for orga¬nizations, committees, and groups of people to under¬take. In all likelihood, we can remember times when a group successfully (or not so successfully) made a deci¬sion. Often, well-thought-out decisions are remembered for their successful impact on the group or community. Likewise, poor decision making by a group will …

Enhancing Homework’S Effectiveness Through Student Motivation And Parental Involvement, Jonathan T. Beutlich

Master of Education Program Theses

Homework has varying degrees of effectiveness; therefore, it is important for teachers to know what elements aid in making homework assignments more effective to learners. There are outside factors that contribute to homework’s effectiveness as well as types of homework assignments that will increase students’ success. Two of the factors contributing to homework’s level of benefits are student motivation and parental involvement. There are three types of homework assignments that increase the positive aspects of student motivation and parental involvement include interspersal assignments, interactive homework assignments, and project-based assignments. Improved homework benefits education, specifically Christian education, by enabling a tightly …

Integrating Landscapes That Have Experienced Rural Depopulation And Ecological Homogenization Into Tropical Conservation Planning, Aerin L. Jacob, Ismael Vaccaro, Raja Sengupta, Joel N. Hartter, Colin A. Chapman

Geography

If current trends of declining fertility rates and increasing abandonment of rural land as a result of urbanization continue, this will signal a globally significant transformation with important consequences for policy makers interested in conservation planning. This transformation is presently evident in a number of countries and projections suggest it may occur in the future in many developing countries. We use rates of population growth and urbanization to project population trends in rural areas for 25 example countries. Our projections indicate a general decline in population density that has either occurred already (e.g., Mexico) or may occur in the future …

The Evolution Of Reciprocity In Sizable Human Groups, Casey G. Rothschild

Economics Faculty Scholarship

The scale and complexity of human cooperation is an important and unresolved evo- lutionary puzzle. This article uses the finitely repeated n person Prisoners’ Dilemma game to illustrate how sapience can greatly enhance group-selection effects and lead to the evolutionary stability of cooperation in large groups. This affords a simple and direct explanation of the human “exception.”

Developing 1990, 2000, And 2005 Impervious Surface Estimates For Southern York County, Maine, David G. Justice, Fay A. Rubin

PREP Reports & Publications

Estimates of impervious surface acreage in 1990, 2000, and 2005 were generated for an 11-town region in York County, Maine, covered by the Piscataqua Region Estuaries Partnership (PREP). The project extended previous work done in New Hampshire, relying on comparable satellite-based data sources and image processing methodologies. As a result, standardized impervious surface estimates are now available for the entirety of the PREP region. The impervious surface estimates were derived by applying both traditional and subpixel classification techniques to 30-meter Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) satellite image data. The classifications indicated that …

Gene Expression Profiles As Molecular Indicators Of Dissolved Oxygen Stress In Grass Shrimp Palaemonetes Pugio Holthuis 1949, Tiandao Li

Dissertations

Occurrence and severity of hypoxia is increasing in coastal and estuarine environments, and recovery of impacted habitats and living resources is slow. Detection of early biological effects of hypoxia is needed for timely remedial action to be taken. The overall objectives of this research was to develop molecular indicators of dissolved oxygen stress to assess the biological impact of hypoxia in coastal estuaries and validate their use through a combination of laboratory and field studies. To achieve these goals, grass shrimp, Palaemonetes pugio, oxygen-sensitive and hypoxia-tolerant species abundant in estuarine systems, were exposed to hypoxia under controlled laboratory conditions, and …

Yellow Head Virus: Transmission And Genome Analyses, Hongwei Ma

Dissertations

Yellow head virus (YHV) is an important pathogen to shrimp aquaculture. Among 13 species of naturally YHV-negative crustaceans in the Mississippi coastal area, the daggerblade grass shrimp, Palaemonetes pugio, and the blue crab, Callinectes sapidus, were tested for potential reservoir and carrier hosts of YHV using PCR and real time PCR. The YHV replicated in the daggerblade grass shrimp, and was still detectable on 36 d post-inoculation, causing 8% mortality after injection. However, YHV did not replicate in the blue crab. These data suggest that the daggerblade grass shrimp could act as a reservoir host for YHV. Storage conditions of …
