Acetate Oxidation Coupled To Fe(Iii) Reduction In Hyperthermophilic Microorganisms, Jason M. Tor, Kazem Kashefi, Derek Lovley Dec 2000

Acetate Oxidation Coupled To Fe(Iii) Reduction In Hyperthermophilic Microorganisms, Jason M. Tor, Kazem Kashefi, Derek Lovley

Derek Lovley

No hyperthermophilic microorganisms have previously been shown to anaerobically oxidize acetate, the key extracellular intermediate in the anaerobic oxidation of organic matter. Here we report that two hyperthermophiles, Ferroglobus placidus and “Geoglobus ahangari,” grow at 85°C by oxidizing acetate to carbon dioxide, with Fe(III) serving as the electron acceptor. These results demonstrate that acetate could potentially be metabolized within the hot microbial ecosystems in which hyperthermophiles predominate, rather than diffusing to cooler environments prior to degradation as has been previously proposed.

Upper White River Bmp Implementation Project (Nps Final Report), Paul F. Vendrell, K. F. Steele, M. A. Nelson, R. W. Mcnew

Technical Reports

The project objective was to monitor agricultural best management practices implemented to minimize sediment, nutrient, and bacterial impact on water quality of the Upper White River watershed. The project targeted the primary agricultural causes of non-point source nutrient and bacterial pollution in three sub-basins of the White River in the Beaver Lake Watershed. Areas with high animal densities targeted high source areas. High source areas were treated with best management practices (BMP) in an effort to reduce the impact to the White River and Beaver Lake. The predominant BMP implemented was waste management, a component of the farm nutrient management ...

Cooperative & Nebraska “Blue Sky” Statutes, J. David Aiken Dec 2000

Cooperative & Nebraska “Blue Sky” Statutes, J. David Aiken

Cornhusker Economics

Cooperative fever is sweeping Nebraska. Agricultural producers are looking for ways to add value to what they produce, often through forming “new generation” cooperatives or by forming limited liability companies (LLCs). New generation cooperatives differ from traditional cooperatives in that new generation cooperatives typically (1) have closed membership and (2) process goods produced by co-op members. New generation cooperatives are more like citrus and other fruit cooperatives that have existed in other parts of the country. The Nebraska Unicameral is providing financial assistance to assist developing these kinds of value-added efforts through LB1348, the “Agricultural Opportunities and Value-Added Partnerships Act ...


Sds-Tolerant Soybean Varieties For Iowa, Michael D. Uphoff Dec 2000

Sds-Tolerant Soybean Varieties For Iowa, Michael D. Uphoff

Integrated Crop Management News

Last year we began testing soybean varieties for tolerance to sudden death syndrome (SDS). Funded by checkoff dollars, we have repeated the test this year with varieties submitted to us by private companies. The SDS tolerance test was conducted in a field near Ames, Iowa. To ensure uniform and consistent disease pressure across plots, we planted dry oats infested with the SDS pathogen along with the soybean seed. Our field experiments show this method, developed by our project at Iowa State University, can provide a consistent level of disease pressure. Details of this method are available upon inquiry.

Impaired Fast-Spiking, Suppressed Cortical Inhibition, And Increased Susceptibility To Seizures In Mice Lacking Kv3.2 K+ Channel Proteins, David Lau, Eleazar Vega-Saenz De Miera, Diego Contreras, Alan Chow, Richard Paylor, Christopher S. Leonard, Bernardo Rudy Dec 2000

Impaired Fast-Spiking, Suppressed Cortical Inhibition, And Increased Susceptibility To Seizures In Mice Lacking Kv3.2 K+ Channel Proteins, David Lau, Eleazar Vega-Saenz De Miera, Diego Contreras, Alan Chow, Richard Paylor, Christopher S. Leonard, Bernardo Rudy

NYMC Faculty Publications

Voltage-gated K(+) channels of the Kv3 subfamily have unusual electrophysiological properties, including activation at very depolarized voltages (positive to -10 mV) and very fast deactivation rates, suggesting special roles in neuronal excitability. In the brain, Kv3 channels are prominently expressed in select neuronal populations, which include fast-spiking (FS) GABAergic interneurons of the neocortex, hippocampus, and caudate, as well as other high-frequency firing neurons. Although evidence points to a key role in high-frequency firing, a definitive understanding of the function of these channels has been hampered by a lack of selective pharmacological tools. We therefore generated mouse lines in which one ...


Amartya Sen And World Food Day 2000, Bettina Klaus Dec 2000

Amartya Sen And World Food Day 2000, Bettina Klaus

Cornhusker Economics

As every year, World Food Day took place on October 16th. Being relatively new to UNL (and the U.S.), and being an assistant professor in the Economics Department (joint with the Agricultural Economics Department) with research interests in social choice and game theory, the probability that I would get involved with World Food Day were slim. However, somehow it caught my eye that the yearly teleconference that accompanies World Food Day featured the 1998 Nobel prize winner for economics, Professor Amartya Sen. The 2000 World Food Day’s teleconference topic was “Poverty and Hunger: The Tragic Link” and in ...


An Intelligent System For Automated Dna Base Calling, Mohamad T. Musavi Dec 2000

An Intelligent System For Automated Dna Base Calling, Mohamad T. Musavi

University of Maine Office of Research Administration: Grant Reports

An investigation into improving the performance of DNA base calling algorithms was conducted. The results have shown that the preprocessing steps performed by ABI sequencer on raw data adversely affects the accuracy of DNA sequencing. This adverse effect has been responsible for relatively high error rates, between 3.5% to 6%, in both ABI and Phred sequencing software. Please note that Phred also uses the processed data generated by ABI sequencer; only their base-calling algorithm is different. To remedy this effect, we have developed and implemented a new filtering technique that preserves the initial information contained in the raw data ...

Hydrologic Analysis Of The Major Tributaries Within The Lower Dan River Watershed Between Milton, Nc And Paces, Va, Juliet Jefferson Brown

Theses, Dissertations & Honors Papers

According to the Clean Water Act of 1972, Virginia is required to develop Total Maximum Daily Loads (TMDLs) for its impaired waters. A TMDL is the maximum amount of particular contaminants that a body of water can accept, without violating federal and state water quality standards. Approximately 130 waters have been targeted for TMDL development, with fecal coliform contamination cited as one of the top five violations.

The purpose of this study was to examine a ten-mile segment of the Dan River that has been designated as impaired, along with seven tributaries that contribute to that segment. The segment is ...

Deducting Environmental Cleanup Costs, Neil Harl Dec 2000

Deducting Environmental Cleanup Costs, Neil Harl

Agricultural Law Digest

For nearly a decade, there’s been a great deal of uncertainty over how to handle environmental cleanup costs. Two developments this year have cast new light on the problem, one confirming the direction we have been taking on the issue and the other raising some question about the reliance on a 1992 U.S. Supreme Court case in requiring the capitalization of some environmental cleanup costs.


Atmospheric Co2 Evasion, Dissolved Inorganic Carbon Production, And Net Heterotrophy In The York River Estuary, Peter Raymond, James E. Bauer, Jonathan Cole Dec 2000

Atmospheric Co2 Evasion, Dissolved Inorganic Carbon Production, And Net Heterotrophy In The York River Estuary, Peter Raymond, James E. Bauer, Jonathan Cole

VIMS Articles

Direct measurements of the partial pressure of CO2 (pCO2) and dissolved inorganic carbon (DIC) were made over a 2‐yr period in surface waters of the York River estuary in Virginia. The pCO2 in surface waters exceeded that in the overlying atmosphere, indicating that the estuary was a net source of CO2 to the atmosphere at most times and locations. Salinity‐based DIC mixing curves indicate there was also an internal source of both DIC and alkalinity, implying net alkalinity generation within the estuary. The DIC and alkalinity source displayed seasonal patterns similar to that of pCO2 and were reproducible ...

Faculty Exchange Program In Second Year At Unl, Lynn Lutgen

Cornhusker Economics

The Agricultural Economics Department joined USDA in a Faculty Exchange Program (FEP) with the Ukraine and Russia in the spring of 1999. Each year four professors from the Ukraine and Russia arrive in Lincoln in August and leave the middle of December. While in Nebraska they take classes, travel, and develop class outlines and news articles that they will use when they return home. This year we have three professors visiting from the Ukraine and one from Russia. The following are their impressions of the U.S. and Nebraska, along with some thoughts on the Faculty Exchange Program.


Quality Of The 2000 Soybean Crop In The United States, Charles R. Hurburgh Jr. Dec 2000

Quality Of The 2000 Soybean Crop In The United States, Charles R. Hurburgh Jr.

Agricultural and Biosystems Engineering Technical Reports and White Papers

Quality, as measured in several ways, is of increasing importance to soybean markets. Since 1972, customers have reported differences in protein and oil contents among soybeans of different origins (Hurburgh, et al., 1990). Geographic differences in composition are primarily caused by weather and environmental factors. In recent years, soybean component variations have been studied extensively (Westgate, et al., 1999). From a customer perspective, monitoring of crop quality on an annual basis is important to estimate outputs and value.


In Vitro Effect Of Shark Cartilage On Human Leukocyte Function, Aline Cornelissen Dec 2000

In Vitro Effect Of Shark Cartilage On Human Leukocyte Function, Aline Cornelissen

FIU Electronic Theses and Dissertations

Previous in vitro studies have shown that shark cartilage extracts stimulate human leukocytes to release significant levels of TNFα, a cytokine typical of a Th1 immune response. The purpose of this study was to investigate further the effects of shark cartilage on cellular immune function, particularly cell proliferation, apoptosis, and IL-4 and INFγ production. The viability and proliferation of cell cultures grown in the presence of shark cartilage extract was not significantly different from unstimulated control cultures or those stimulated with mitogens (Con A, PMA, LPS), respectively. The effect of shark cartilage on apoptosis was determined by microscopic analysis of ...

Sensitivity Of Species Habitat-Relationship Model Performance To Factors Of Scale, J. W. Karl, P. J. Heglund, E. O. Garton, J. M. Scott, N. M. Wright, Richard L. Hutto Dec 2000

Sensitivity Of Species Habitat-Relationship Model Performance To Factors Of Scale, J. W. Karl, P. J. Heglund, E. O. Garton, J. M. Scott, N. M. Wright, Richard L. Hutto

Biological Sciences Faculty Publications

Researchers have come to different conclusions about the usefulness of habitat-relationship models for predicting species presence or absence. This difference frequently stems from a failure to recognize the effects of spatial scales at which the models are applied. We examined the effects of model complexity, spatial data resolution, and scale of application on the performance of bird habitat relationship (BHR) models on the Craig Mountain Wildlife Management Area and on the Idaho portion of the U.S. Forest Service's Northern Region. We constructed and tested BHR models for 60 bird species detected on the study areas. The models varied ...


Characterization Of Borrelia Burgdorferi Blya And Blyb Proteins: A Prophage-Encoded Holin-Like System, Christopher J. Damman, Christian H. Eggers, D. Scott Samuels Dec 2000

Characterization Of Borrelia Burgdorferi Blya And Blyb Proteins: A Prophage-Encoded Holin-Like System, Christopher J. Damman, Christian H. Eggers, D. Scott Samuels

Biological Sciences Faculty Publications

The conserved cp32 plasmid family of Borrelia burgdorferi was recently shown to be packaged into a bacteriophage particle (C. H. Eggers and D. S. Samuels, J. Bacteriol. 181:7308-7313, 1999), This plasmid encodes BlyA, a 7.4-kDa membrane-interactive protein, and BlyB, an accessory protein, which were previously proposed to comprise a hemolysis system. Our genetic and biochemical evidence suggests that this hypothesis is incorrect and that BlyA and BlyB function instead as a prophage-encoded holin or holin-like system for this newly described bacteriophage, An Escherichia coli mutant containing the blyAB locus that was defective for the normally cryptic host hemolysin ...


Hemin-Binding Surface Protein From Bartonella Quintana, James A. Carroll, Sherry A. Coleman, Laura S. Smitherman, Michael F. Minnick Dec 2000

Hemin-Binding Surface Protein From Bartonella Quintana, James A. Carroll, Sherry A. Coleman, Laura S. Smitherman, Michael F. Minnick

Biological Sciences Faculty Publications

Bartonella quintana, the agent of trench fever and a cause of endocarditis and bacillary angiomatosis in humans, has the highest reported in vitro hemin requirement for any bacterium. We determined that eight membrane-associated proteins from B. quintana bind hemin and that a similar to 25-kDa protein (HbpA) was the dominant hemin binding protein. Like many outer membrane proteins, HbpA partitions to the detergent phase of a Triton X-114 extract of the cell and is heat modifiable, displaying an apparent molecular mass shift from approximately 25 to 30 kDa when solubilized at 100 degreesC. Immunoblots of purified outer and inner membranes ...


Ryanodine Receptor Adaptation, Michael Fill, A. Zahradníková, Carlos A. Villalba-Galea, I. Zahradník, A. L. Escobar, S. Györke Dec 2000

Ryanodine Receptor Adaptation, Michael Fill, A. Zahradníková, Carlos A. Villalba-Galea, I. Zahradník, A. L. Escobar, S. Györke

School of Pharmacy and Health Sciences Faculty Articles

In the heart, depolarization during the action potential activates voltage-dependent Ca2+ channels that mediate a small, localized Ca2+ influx (ICa). This small Ca2+ signal activates specialized Ca2+ release channels, the ryanodine receptors (RyRs), in the sarcoplasmic reticulum (SR). This process is called Ca2+-induced Ca2+ release (CICR). Intuitively, the CICR process should be self-regenerating because the Ca2+ released from the SR should feedback and activate further SR Ca2+ release. However, the CICR process is precisely controlled in the heart and, consequently, some sort of negative control mechanism(s) must exist to ...
