Lake Naconiche Archaeology And Caddo Origins Issues, Timothy K. Perttula

Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State

Sometime around ca. A.D. 800, Lake Naconiche sites were no longer occupied by Woodland period groups of the Mossy Grove culture solely making sandy paste pottery or living as mobile hunting-gathering foragers. At this time, from ca. A.D. 750-800 to around A.D. 900, colder and drier conditions began to dominate the local weather. After ca. A.D. 800, were the aboriginal groups Caddo peoples or acculturated Mossy Grove folks? Some findings from the Lake Naconiche archaeological investigations at the Boyette site (41NA285) are relevant to this issue of ethnic affiliations and local, but nevertheless regional momentous, cultural changes.

How Can A Video Game Cause Panic Attacks? 1. Effects Of An Auditory Stressor On The Human Brainstem, Judith Lauter, Elizabeth Mathukutty, Brandon Scott

Faculty Publications

The auditory brainstem response (ABR) was recorded during simultaneous binaural presentation of two types of sounds: 1) condensation clicks presented through in-the-ear earphones at 43.1/sec, 60dB nHL; and 2) recordings of breathing sounds, presented through supra-aural headphones, at levels adjusted by participants to be equivalent to the clicks. In alternate blocks, the breathing sounds were either: 1) a recording of quiet breathing (blocks 1, 3, 5); or 2) a recording of erratic (stressed) breathing (blocks 2, 4). The erratic breathing was modeled on a video game soundtrack in which the character was represented as running, wounded, and frightened. Four 2048-sweep …

Estimating Waterfowl Densities In A Flooded Forest: A Comparison Of Methods, R. Montague Whiting Jr., J. Paul Cornes

Faculty Presentations

During winter, aerial surveys are used to estimate densities of ducks that occupy open-water habitats. However, such surveys are ineffective for sampling forest-dwelling species, especially Aix sponsa (Wood Ducks), Anas platyrhynchos (Mallards), and Lophodytes cucullatus (Hooded Mergansers). We evaluated fixed-radius plot (FRP) and Reynolds and Goodrum variable-radius plot (VRP) methods for estimating waterfowl densities in a flooded hardwood bottomland. We constructed 15 elevated blinds on the Angelina River flood plain in eastern Texas and established a 1-ha FRP around each blind; color-coded markers were placed at fixed intervals from each blind. Observers surveyed waterfowl from blinds for 21 mornings during …

Functions And Evolution Of Selenoprotein Methionine Sulfoxide Reductases, Byung Cheon Lee, Alexander Dikiy, Hwa-Young Kim, Vadim N. Gladyshev

Vadim Gladyshev Publications

Methionine sulfoxide reductases (Msrs) are thiol-dependent enzymes which catalyze conversion of methionine sulfoxide to methionine. Three Msr families, MsrA, MsrB, and fRMsr, are known. MsrA and MsrB are responsible for the reduction of methionine-S-sulfoxide and methionine-R-sulfoxide residues in proteins, respectively, whereas fRMsr reduces free methionine-R-sulfoxide. Besides acting on proteins, MsrA can addi¬tionally reduce free methionine-S-sulfoxide. Some MsrAs and MsrBs evolved to utilize catalytic selenocysteine. This includes MsrB1, which is a major MsrB in cytosol and nucleus in mammalian cells. Specialized machinery is used for insertion of selenocysteine into MsrB1 and other seleno¬proteins at in-frame UGA codons. Selenocysteine offers catalytic advantage …

Selenoproteins That Function In Cancer Prevention And Promotion, Dolph L. Hatfield, Min-Hyuk Yoo, Bradley A. Carlson, Vadim N. Gladyshev

Vadim Gladyshev Publications

Of the many health benefits attributed to selenium, the one that has received the most attention is its role in cancer prevention. Selenium-containing proteins (selenoproteins) have been shown in recent years to have roles in cancer prevention. However, selenoproteins have diverse functions and their view as antioxidants is oversimplified. Some selenoproteins appear to have a split personality in having roles both in preventing and promoting cancer. The contrasting roles of one selenoprotein, thioredoxin reductase 1, in cancer are discussed in detail, but as also noted, at least one other selenoprotein may also have such a dual function. In addition, we …

Identification Of A Novel System For Boron Transport: Atr1 Is A Main Boron Exporter In Yeast, Alaattin Kaya, Huseyin C. Karakaya, Dmitri E. Fomenko, Vadim N. Gladyshev, Ahmet Koc

Vadim Gladyshev Publications

Boron is a micronutrient in plants and animals, but its specific roles in cellular processes are not known. To understand boron transport and functions, we screened a yeast genomic DNA library for genes that confer resistance to the element in Saccharomyces cerevisiae. Thirty boron-resistant transformants were isolated, and they all contained the ATR1 (YML116w) gene. Atr1 is a multidrug resistance transport protein belonging to the major facilitator superfamily. C-terminal green fluorescent protein-tagged Atr1 localized to the cell membrane and vacuole, and ATR1 gene expression was upregulated by boron and several stress conditions. We found that atr1Δ mutants were …

In addition, illustrations of the male and female genitalia of the adults, larval chaetotaxal maps, and scanning electron micrographs for both species are included. The pupa of only C. camilotus was available for description.

Two New Species Of Wockia Heinemann (Lepidoptera: Urodidae) From Coastal Dry-Forests In Western Mexico, David Adamski, Karina Boege, Jean-Francois Landry, Jae-Cheon Sohn

USDA Systematic Entomology Laboratory

Two new species of Wockia Heinemann, 1870 (Lepidoptera: Urodidae), W. chewbacca and W. mexicana, are described from primary dry-forests in western Mexico. A new host record is reported for the genus from larvae of W. chewbacca feeding on leaves of Casearia nitida (L.) Jacq. (Salicaceae). Several shared genitalic features and DNA barcode similarities suggest a congeneric relationship between the two Mexican species but uncertain generic placement within Urodidae. Scanning electron micrographs of the larva and illustrations of the larva and pupa of Wockia chewbacca are provided, along with illustrations of male and female genitalia of both Mexican species. Three …

Resolving The Lateral Component Of Blood Flow Velocity Based On Ultrasound Speckle Size Change With Scan Direction And Speed, Tiantian Xu, Greg R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional blood flow velocity measurement using ultrasound is capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these Doppler-based methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. In this paper, we introduce a method which estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to the blood reflectors (typically red blood cells) stretches (i.e., is “smeared”) if …

Further Progress On Lateral Flow Estimation Using Speckle Size Variation With Scan Direction, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional blood flow velocity measurement using ultrasound is capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these Doppler-based methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. In this paper, we report additional data on a new method recently introduced. This method estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to the blood reflectors (typically red …

Single Molecule Diffusion Coefficient Estimation By Image Analysis Of Simulated Ccd Images To Aid High-Throughput Screening, Pengfei Song, Lloyd M. Davis, Greg Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Extension of one-dimensional signal analysis to two-dimensional image analysis could accelerate conventional methods of high-throughput screening in the discovery of new pharmaceutical agents. This work describes a first step taken towards this goal – the evaluation of image-analysis based estimation strategies of the diffusion coefficient of a single molecule transported within a microfabricated flowcell. A computer simulation of single-molecule imaging by a charge-coupled device (CCD) camera is used to determine if it is possible to distinguish three different types of molecules with different diffusion coefficients. The Gaussian fitting algorithm finds the variance of the transverse trajectory, which increases linearly with …

Optimal Thresholds Of Feature Tracking For Blood Velocity And Tissue Motion Estimation, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Feature tracking is an algorithm for estimating blood flow velocity and tissue motion using pulse-echo ultrasound. In contrast to cross-correlation speckle-tracking techniques, feature tracking identifies features at discrete locations and corresponds them from frame to frame. Prior studies have demonstrated that feature-tracking estimates exhibit lower variance than those obtained by the conventional autocorrelation method and require less computational complexity than either speckle tracking or autocorrelation. To date, not much attention has been paid to the process by which trackable features (normally local maxima) are selected from the set of all available features. In the selection process, it is desired to …

Desalination: Status And Federal Issues, Nicole T. Carter

Congressional Research Service Reports

In the United States, desalination is increasingly investigated as an option for meeting municipal water demands, particularly for coastal communities that can desalinate seawater or estuarine water, interior communities above brackish groundwater aquifers, and communities with contaminated water supplies. Adoption of desalination, however, remains constrained by financial, environmental, regulatory, and other factors. At issue is what role Congress establishes for the federal government in desalination research and development, and in construction and operational costs of desalination demonstration projects and full-scale facilities.

Desalination processes generally treat seawater or brackish water to produce a stream of freshwater, and a separate, saltier stream …

Biotechnology In Animal Agriculture: Status And Current Issues, Geoffrey S. Becker, Tadlock Cowan

Congressional Research Service Reports

Animal agriculture is being transformed by rapid advances in biotechnology—a term that encompasses a variety of technologies, including genetic engineering (GE), genetic modification, transgenics, recombinant DNA techniques, and cloning, among others. Producers are interested in the application of biotechnology to improve productivity, consistency, and quality; to introduce new food, fiber, and medical products; and to protect the environment. Potential human health applications of transgenic animals include producing biopharmaceuticals and generating organs, tissues, and cells for xenotransplantation. Criticisms of such applications involve issues ranging from food safety and social resistance to potential negative impacts on animal welfare and on ecosystems. Questions …

The National Bio- And Agro-Defense Facility: Issues For Congress, Dana A. Shea, Jim Monke, Frank Gottron

Congressional Research Service Reports

The agricultural and food infrastructure of the United States may be susceptible to terrorist attack using biological pathogens. In addition to the economic effects of such an attack, some animal pathogens could cause illness in humans. Diseases that can spread from animals to people are known as zoonotic diseases. Scientific and medical research on plant and animal diseases may lead to the discovery and development of new diagnostics and countermeasures, reducing the risk and effects of a successful terrorist attack.

To safeguard the United States against the introduction of non-native animal disease, Congress has appropriated funds to the U.S. Department …

Whales And Sonar: Environmental Exemptions For The Navy's Mid-Frequency Active Sonar Training, Kristina Alexander

Congressional Research Service Reports

Mid-frequency active (MFA) sonar emits pulses of sound from an underwater transmitter to help determine the size, distance, and speed of objects. The sound waves bounce off objects and reflect back to underwater acoustic receivers as an echo. MFA sonar has been used since World War II, and the Navy indicates it is the only reliable way to track submarines, especially more recently designed submarines that operate more quietly, making them more difficult to detect.

Scientists have asserted that sonar may harm certain marine mammals under certain conditions, especially beaked whales. Depending on the exposure, they believe that sonar may …

Federal Research And Development Funding: Fy2009, John F. Sargent Jr.

Congressional Research Service Reports

In February 2008, President Bush proposed total research and development (R&D) funding of $147.0 billion in his FY2009 budget request to Congress, a $3.9 billion (2.7%) increase over the estimated FY2008 level of $143.1 billion.

Cell Block Preparation From Cytology Specimen With Predominance Of Individually Scattered Cells, George M. Varsegi, Vinod B. Shidham

Department of Pathology

This article with accompanied video demonstrates Shidham's method for preparation of cell blocks from liquid based cervicovaginal cytology specimens containing individually scattered cells and small cell groups. This technique uses HistoGel (Thermo Scientific) with conventional laboratory equipment.

The use of cell block sections is a valuable ancillary tool for evaluation of non-gynecologic cytology. They enable the cytopathologist to study additional morphologic specimen detail including the architecture of the lesion. Most importantly, they allow for the evaluation of ancillary studies such as immunocytochemistry, in-situ hybridization tests (FISH/CISH) and in-situ polymerase chain reaction (PCR). Traditional cell block preparation techniques have mostly been …

Range Management And Soil Seed Bank: New Perspective, Lan Xu, Brent E. Turnipseed, Roger N. Gates, Patricia Johnson, Nels H. Troelstrup Jr.

Oak Lake Field Station Research Publications

Seed banks are considered essential constituents of plant communities and contribute significantly to ecological processes. Seed banks play a critical role in managing the composition and structure of existing vegetation, restoring native vegetation, creating habitat for animals, preserving genetic diversity, and recovering endangered plant species. Therefore, implementation of management practices based only on existing aboveground vegetation, without the information of soil seed flora is obviously incomplete and dangerous. Our objectives were to determine effects of prescribed burning and reseeding managements on soil seed bank composition and the relationship between the soil seed bank and aboveground vegetation. The study was conducted …

Mentum Deformation Of Chironomidae Subfamilies, Funtional Feeding, Guilds, And Habitat Guilds Within The Cheyenne River Basin, South Dakota, Andrew Kopp, Nels H. Troelstrup Jr.

Oak Lake Field Station Research Publications

Toxic score is a tool devised by Lenat (1993 Journal of the North American Benthological Society 12:265-269). Using mentum deformities of Chironomus larvae to evaluate the effects of toxicity and organic loading in streams. It uses mentum deformities within Chironomus to score a site for toxicity. Slight (Class 1), conspicuous (Class 2) and severe (Class 3) deformities are enumerated and used to generate the toxic score for each site. The purpose of this study was to document frequencies of deformities across Chironomidae subfamilies, functional feeding guilds, and habit guilds. Macroinvertebrate samples were collected from the Cheyenne River Basin 10 times …

Spatial Interactions In The Macoma Balthica Community Control Biogeochemical Fluxes At The Sediment-Water Interface And Microbial Abundances, Emma Michaud, Gaston Desrosiers, Robert C. Aller, Florian Mermillod-Blondin, Bjorn Sundby, Georges Stora

Journal of Marine Research

We examined how interactions among the three dominant species of the Macoma balthica community in the St-Lawrence estuary influence net biogeochemical fluxes and the composition of the sedimentary bacterial community. We manipulated the biodiversity of the community via combinations of Macoma balthica, Mya arenaria, and Nereis virens in sediment microcosms containing sieved and homogenized tidal-flat sediment. Each combination was adjusted to similar total biovolumes and in situ animal densities. Compared to treatments with single species, which were also adjusted to similar biovolumes and densities, combinations of multiple species changed the fluxes of oxygen, phosphate, ammonium, and nitrate across the sediment-water …
