Binding Of Equine Infectious Anemia Virus Rev To An Exon Splicing Enhancer Mediates Alternative Splicing And Nuclear Export Of Viral Mrnas, Michael Belshan, Gregory S. Park, Patricia Bilodeau, C. Martin Stoltzfus, Susan Carpenter May 2000

Binding Of Equine Infectious Anemia Virus Rev To An Exon Splicing Enhancer Mediates Alternative Splicing And Nuclear Export Of Viral Mrnas, Michael Belshan, Gregory S. Park, Patricia Bilodeau, C. Martin Stoltzfus, Susan Carpenter

Nebraska Center for Virology: Faculty Publications

In addition to facilitating the nuclear export of incompletely spliced viral mRNAs, equine infectious anemia virus (EIAV) Rev regulates alternative splicing of the third exon of the tat/rev mRNA. In the presence of Rev, this exon of the bicistronic RNA is skipped in a fraction of the spliced mRNAs. In this report, the cis-acting requirements for exon 3 usage were correlated with sequences necessary for Rev binding and transport of incompletely spliced RNA. The presence of a purine-rich exon splicing enhancer (ESE) was required for exon 3 recognition, and the addition of Rev inhibited exon 3 splicing. Glutathione-S-transferase (GST)-Rev bound …

Ion-Kill Dosimetry, Robert Katz, F. A. Cucinotta, M. Fromm, A. Chambaudet May 2000

Ion-Kill Dosimetry, Robert Katz, F. A. Cucinotta, M. Fromm, A. Chambaudet

Robert Katz Publications

Unanticipated late effects in neutron and heavy ion therapy, not attributable to overdose, imply a qualitative difference between low and high LET therapy. We identify that difference as ‘ion kill’, associated with the spectrum of z/β in the radiation field, whose measurement we label ‘ion-kill dosimetry’.


Evaluation Of Stomoxys Calcitrans (Diptera: Muscidae) Behavioral Response To Human And Related Odors In A Triple Cage Olfactometer With Insect Traps, Raul A. Alzogaray, David A. Carlson May 2000

Evaluation Of Stomoxys Calcitrans (Diptera: Muscidae) Behavioral Response To Human And Related Odors In A Triple Cage Olfactometer With Insect Traps, Raul A. Alzogaray, David A. Carlson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A triple cage olfactometer provided with insect traps was used for evaluating behavioral responses of Stomoxys calcitrans (L.) females to human skin and breath, CO2, and L-lactic acid analogs. After demonstrating there were no significant differences caused by cage location or time of day, 3 sets of 3 olfactometer tests were performed in a day, every 2 h beginning at 0900 hours. When a human hand was used as attractant, the attraction (expressed as percentage of trapped flies) increased as a function of the time; an inverted U-shaped relationship between attractancy and air speed was observed; and variation …

Ceftriaxone-Resistant Salmonella Infection Acquired By A Child From Cattle, Paul D. Fey, Thomas J. Safranek, Mark E. Rupp, Eileen F. Dunne, Efrain Ribot, Peter C. Iwen, Patricia A. Bradford, Frederick J. Angulo, Steven H. Hinrichs

Zoonotics and Wildlife Disease: Publications

Background
The emergence of resistance to antimicrobial agents within the salmonellae is a worldwide problem that has been associated with the use of antibiotics in livestock. Resistance to ceftriaxone and the fluoroquinolones, which are used to treat invasive salmonella infections, is rare in the United States. We analyzed the molecular characteristics of a ceftriaxone-resistant strain of Salmonella enterica serotype typhimurium isolated from a 12-year-old boy with fever, abdominal pain, and diarrhea.
Methods
We used pulsed-field gel electrophoresis and analysis of plasmids and β-lactamases to compare the ceftriaxone-resistant S. enterica serotype typhimurium from the child with four isolates of this strain …


Wildlife Strikes: A Growing And Costly Problem For Civil Aviation In The Usa, Sandra Wright, Richard Dolbeer Apr 2000

Wildlife Strikes: A Growing And Costly Problem For Civil Aviation In The Usa, Sandra Wright, Richard Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife strikes, defined as aircraft collisions with birds or other animals, are a serious safety and economic concern in the USA and elsewhere. Liability issues related to wildlife strikes are also growing for airports and aircraft operators. In this paper, we will give examples of some significant strikes, show trends in wildlife strikes, explain why the strike problem is an increasing concern and discuss what actions can be taken to reduce and prevent strikes.


Seasonal Variability In Brown Tree Snake (Boiga Irregularis) Response To Lures, John A. Shivik, William G. Wright, Larry Clark Apr 2000

Seasonal Variability In Brown Tree Snake (Boiga Irregularis) Response To Lures, John A. Shivik, William G. Wright, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

In continuing investigations of brown tree snake, Boiga irregularis, attraction to carrion odor, we hypothesized that the attractiveness of live or dead and visually apparent or concealed lures varies seasonally. We determined that lure condition (live or dead mouse lures) and sensory cues (visually apparent or concealed lure) interact among wet and dry seasons. Concealed carrion lures were more effective during the dry season than the wet season, but the effectiveness of live mouse lures showed less seasonal variability. We identified weather variables that covary with observed seasonal trends in capture rates and investigated the influence of recent feeding …


Immunocontraception Of White-Tailed Deer With Gnrh Vaccine, Lowell A. Miller, Brad E. Johns, Gary J. Killian Apr 2000

Immunocontraception Of White-Tailed Deer With Gnrh Vaccine, Lowell A. Miller, Brad E. Johns, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

One of the most successful immunocontraceptive vaccines used for wildlife is porcine zona pellucida (PZP). Several authors have published on the use of PZP immunocontraceptive vaccines to immunosterilize white-tailed deer. This is the first long term study of the use of GnRH contraception of deer. This GnRH immunocontraceptive study was part of a multi-year White- Tailed deer infertility study on the deer herd at Pennsylvania State University, (PSU) University Park, Pennsylvania in cooperation with National Wildlife Research Center, (NWRC) Fort Collins, CO.

Reporting Bias In Bird Strikes At John F Kennedy International Airport, New York, 1979-1998, Scott C. Barras, Richard A. Dolbeer Apr 2000

Reporting Bias In Bird Strikes At John F Kennedy International Airport, New York, 1979-1998, Scott C. Barras, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Bird-aircraft strike databases have been used to identify, monitor, and manage bird strike problems in the USA nationally and at individual airports. Up to 75% of all bird strikes that occur in the USA may not be reported by pilots or airport control tower personnel. Recent studies have suggested that individual airports may improve their strike reporting rates by having personnel regularly search runways for the remains of birds struck by aircraft. We analyzed a 20-year dataset of runway searches from John F. Kennedy International Airport (JFKIA) in New York to determine the degree of bias in reports of strikes …


Method And Apparatus For Three-Dimensional Ultrasound Imaging Of Biopsy Needle, Syed Omar Ishrak, Mir Said Seyed-Bolorforosh, William Thomas Hatfield, Todd Michael Tillman, Brian Peter Geiser, Gregory R. Bashford, Michael Joseph Washburn Apr 2000

Method And Apparatus For Three-Dimensional Ultrasound Imaging Of Biopsy Needle, Syed Omar Ishrak, Mir Said Seyed-Bolorforosh, William Thomas Hatfield, Todd Michael Tillman, Brian Peter Geiser, Gregory R. Bashford, Michael Joseph Washburn

Biomedical Imaging and Biosignal Analysis Laboratory

A method and an apparatus for three-dimensional ultrasound imaging of a needle-like instrument, such as a biopsy needle, inserted in a human body. The instrument is visualized by transmitting ultrasound beams toward the instrument and then detecting the echo signals using a linear array of transducer elements. The problem of ultrasound being reflected from a biopsy needle in a direction away from the transducer array is solved by steering the transmitted ultrasound beams t increase the angle at which the beams impinge upon the biopsy needle. Ideally the ultrasound beams are perpendicular to the needle. This increases the system's sensitivity …


Carbon Nanotube Atomic Force Microscopy Tips: Direct Growth By Chemical Vapor Deposition And Application To High-Resolution Imaging, Chin Li Cheung, Jason H. Hafner, Charles M. Lieber Apr 2000

Carbon Nanotube Atomic Force Microscopy Tips: Direct Growth By Chemical Vapor Deposition And Application To High-Resolution Imaging, Chin Li Cheung, Jason H. Hafner, Charles M. Lieber

Barry Chin Li Cheung Publications

Carbon nanotubes are potentially ideal atomic force microscopy probes because they can have diameters as small as one nanometer, have robust mechanical properties, and can be specifically functionalized with chemical and biological probes at the tip ends. This communication describes methods for the direct growth of carbon nanotube tips by chemical vapor deposition (CVD) using ethylene and iron catalysts deposited on commercial silicon-cantilever-tip assemblies. Scanning electron microscopy and transmission electron microscopy measurements demonstrate that multiwalled nanotube and single-walled nanotube tips can be grown by predictable variations in the CVD growth conditions. Force-displacement measurements made on the tips show that they …


Roles Of Odor, Taste, And Toxicity In The Food Preferences Of Lambs: Implications For Mimicry In Plants, Frederick D. Provenza, Bruce A. Kimball, Juan J. Villalba Apr 2000

Roles Of Odor, Taste, And Toxicity In The Food Preferences Of Lambs: Implications For Mimicry In Plants, Frederick D. Provenza, Bruce A. Kimball, Juan J. Villalba

United States Department of Agriculture Wildlife Services: Staff Publications

In the traditional sense, food ingestion consists of prehending, masticating, swallowing, and digesting plant matter. It is also possible to ingest plants without eating them. Volatile compounds are inhaled directly into the lungs and transported from the lungs into the bloodstream. Volatiles in high concentrations could presumably produce toxicosis, without an herbivore ever ingesting a plant in the customary sense. Volatile compounds may be aposematic, serving to warn potential predators of toxins in plants. We conducted three experiments to explore the roles of odor, taste, and toxicity in the food preferences of lambs. The first experiment determined if brief exposure …

Wastewater Management Using Hybrid Poplar, Gary A. Kuhn Apr 2000

Wastewater Management Using Hybrid Poplar, Gary A. Kuhn

Agroforestry Notes (USDA-NAC)

Hybrid poplars are rapidly growing trees that are well suited to use agricultural, industrial, and community wastewater. They are being used as an alternative to expensive wastewater treatment systems, and methods which apply wastewater to annual crops or pasture. The trees serve a dual purpose as a nutrient sink for wastewater use and as a means to produce a short-rotation harvested wood product which helps offset the cost of installation and maintenance.

Planning tree wastewater use systems requires both agroforestry and engineering expertise. Omission of either in the planning process can lead to disappointing results and reduced benefits. This Agroforestry …


Waterbreaks: Managed Trees For The Floodplain, Douglas C. Wallace, Wayne A. Geyer, John P. Dwyer Apr 2000

Waterbreaks: Managed Trees For The Floodplain, Douglas C. Wallace, Wayne A. Geyer, John P. Dwyer

Agroforestry Notes (USDA-NAC)

Historically, many of the natural woody ecosystems that were once present in floodplains across the country have been highly altered or removed. Land clearing has resulted in the loss of woody vegetation, even in areas adjacent to streams and rivers. With these alterations, came extensive flood management commitments to compensate for the loss of naturally functioning floodplains and for the protection of towns, roads, and agricultural fields. However, even with the best available flood management techniques, when rivers decide to flood - they will, often with devastating consequences. Strictly from a social and an economic standpoint, allowing the floodplain to …

Juvenile Hormone Titer And Morph-Specific Reproduction In The Wing-Polymorphic Cricket, Gryllus Firmus, Gretchen Cisper, Anthony J. Zera, David W. Borst Apr 2000

Juvenile Hormone Titer And Morph-Specific Reproduction In The Wing-Polymorphic Cricket, Gryllus Firmus, Gretchen Cisper, Anthony J. Zera, David W. Borst

Anthony Zera Publications

Juvenile hormone titers and reproductive characteristics were measured in adult wing and flight-muscle morphs of the wing-polymorphic cricket, Gryllus firmus, during the first week of adulthood. This species has three morphs: one flight capable morph with fully-developed wings and fully-developed flight muscles [LW(F)], one flightless morph with fully-developed wings and histolyzed (non-functional) flight muscles [LW(H)], and another flightless morph with underdeveloped (short) wings and underdeveloped flight muscles (SW). Both flightless morphs [LW(H) and SW] had larger ovaries which contained a greater number of postvitellogenic eggs compared with the flight capable [LW(F)] morph. The juvenile hormone titer was significantly higher …


Immunoaffinity Chomatography, Anuradha Subramanian Apr 2000

Immunoaffinity Chomatography, Anuradha Subramanian

Papers in Biotechnology

Recent devclopments in recombinant DNA technology have enabled the synthesis of valuable therapeutic proteins in bacterial cells as well as in novel eucaryotic expression systems. However, the purification of proteins of interest from either the conventional sources, cell culture, or novel routes in a highly purified form necessitates the development of separation tcchniques capable of recovering proteins from these feed streams in a highly purified form (1,2). Purification of therapeutic proteins from biological sources is usually complicated by the presence of endogenous proteins (2). Purification methodologies based on ion exchange or adsorption serve as excellent prepurification steps, but they fail …

Enjoy The Donut: A Regulatory Response To The White Paper On Preventing Invasion Of The Great Lakes By Exotic Species, Sandi Zellmer Apr 2000

Enjoy The Donut: A Regulatory Response To The White Paper On Preventing Invasion Of The Great Lakes By Exotic Species, Sandi Zellmer

Nebraska College of Law: Faculty Publications

The adverse economic and environmental consequences associated with the invasion and establishment of exotic species have raised significant concerns among the Great Lakes community. In September 1999, the International Joint Commission (IJC) hosted a workshop on exotic policy, drawing upon the expertise of biologists, lawyers and public officials, to consider means of preventing exotic species invasions. The White Paper on Policies for the Prevention of the Invasion of the Great Lakes by Exotic Organisms served as the centerpiece for discussion at the workshop.

The White Paper concludes that economic initiatives, such as subsidies or taxation, would be the most viable …

Review Of Men As Women, Women As Men: Changing Gender In Native American Cultures By Sabine Lang, Claire R. Farrer Apr 2000

Review Of Men As Women, Women As Men: Changing Gender In Native American Cultures By Sabine Lang, Claire R. Farrer

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Some prefer to read books by going directly to the crux, bypassing any Preface or Introduction. To do so with this book would create confusion, as Lang uses terms idiosyncratically. She defines her terms well, however, presents justifications for employing them, and provides an overview of the study and how she came to write it in both its English and German editions. All this is vital information for those approaching the text.

It has become standard among scholars writing in English to refer to people of mixed, blended, or other genders using first the term for the person's biological sex …

The Platte As A Prairie River: A Response To Johnson And Boettcher, Paul J. Currier, Craig A. Davis Apr 2000

The Platte As A Prairie River: A Response To Johnson And Boettcher, Paul J. Currier, Craig A. Davis

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Johnson and Boettcher (2000) question the status of the presettlement Platte River as a prairie river, and they argue that it was "a wooded river traversing a prairie landscape." Here we review evidence in support of the prairie river concept, suggesting the channels of the Platte were predominantly open and largely absent of trees. Direct support for a prairie river is found in the detailed map drawn by Lieutenant Woodbury in locating the site for Fort Kearny in 1847. Woodbury showed a thin strip of timber, located in an area that appeared to be elevated above the influence of active …
