Mast Cell Regulation Of The Immune Response, John J. Ryan, Johanna K. Morales, Yves T. Falanga, Josephine Fa Fernando, Matthew R. Macey Jan 2009

Mast Cell Regulation Of The Immune Response, John J. Ryan, Johanna K. Morales, Yves T. Falanga, Josephine Fa Fernando, Matthew R. Macey

Biology Publications

Mast cells are well known as principle effector cells of type I hypersensitivity responses. Beyond this role in allergic disease, these cells are now appreciated as playing an important role in many inflammatory conditions. This review summarizes the support for mast cell involvement in resisting bacterial infection, exacerbating autoimmunity and atherosclerosis, and promoting cancer progression. A commonality in these conditions is the ability of mast cells to elicit migration of many cell types, often through the production of inflammatory cytokines such as tumor necrosis factor. However, recent data also demonstrates that mast cells can suppress the immune response through interleukin-10 …


An Investigation Of The Behavioral Mechanisms Of Antipsychotic Action Using A Drug-Drug Conditioning Paradigm, Ming Li, Wei He, Alexa Mead Jan 2009

An Investigation Of The Behavioral Mechanisms Of Antipsychotic Action Using A Drug-Drug Conditioning Paradigm, Ming Li, Wei He, Alexa Mead

Department of Psychology: Faculty Publications

Antipsychotic drugs at noncataleptic doses selectively suppress conditioned avoidance response in rats. In our previous study, we had used a two-way active avoidance response paradigm to show that the antipsychotic-induced interoceptive state is one of the mechanisms underlying the avoidance-disruptive effect of antipsychotics. In this study, we sought to further examine this mechanism using a novel drug-drug conditioning procedure. We made use of the fact that both the typical neuroleptic haloperidol and the atypical neuroleptic olanzapine disrupt conditioned avoidance responding, whereas chlordiazepoxide (an anxiolytic) does not. We reasoned that if the antipsychotic interoceptive state is important in causing a disruption …


A Cross-Comparison Of Field, Spectral, And Lidar Estimates Of Forest Canopy Cover, Alistair M.S. Smith, Michael J. Falkowski, Andrew T. Hudak, Jeffrey S. Evans, Andrew P. Robinson, Caiti M. Steele Jan 2009

A Cross-Comparison Of Field, Spectral, And Lidar Estimates Of Forest Canopy Cover, Alistair M.S. Smith, Michael J. Falkowski, Andrew T. Hudak, Jeffrey S. Evans, Andrew P. Robinson, Caiti M. Steele

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

A common challenge when comparing forest canopy cover and similar metrics across different ecosystems is that there are many field- and landscape-level measurement methods. This research conducts a cross-comparison and evaluation of forest canopy cover metrics produced using unmixing of reflective spectral satellite data, light detection and ranging (lidar) data, and data collected in the field with spherical densiometers. The coincident data were collected across a ~25 000 ha mixed conifer forest in northern Idaho. The primary objective is to evaluate whether the spectral and lidar canopy cover metrics are each statistically equivalent to the field-based metrics. The secondary objective …

How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand Jan 2009

How Do Animal Mitochondria Tolerate Water Stress?, Michael A. Menze, Steven C. Hand

Faculty Research & Creative Activity

The vast majority of animal species do not tolerate severe water stress, but the encysted embryo of the brine shrimp Artemia franciscana is an exceptionally useful organism to investigate physiological mechanisms for enduring extreme environmental insults. Any substantial reduction in cellular water poses a threat to survival. Nevertheless anhydrobiotic animals survive virtually complete loss of cellular water. The mechanisms that govern “life without water” (anhydrobiosis) are still not well understood. With certain exceptions, it seems that a recurring strategy for tolerating severe water loss involves the accumulation of both low molecular weight solutes (e.g. trehalose or other polyol) and highly …

Investigation Of Insect Visits To Flowers Of Stylisma Pickeringii (Patterson Bindweed), An Endangered Plant Of Illinois Sand Prairies, A. E. Claerbout, H. R. Owen, Janice M. Coons, B. L. Todd Jan 2009

Investigation Of Insect Visits To Flowers Of Stylisma Pickeringii (Patterson Bindweed), An Endangered Plant Of Illinois Sand Prairies, A. E. Claerbout, H. R. Owen, Janice M. Coons, B. L. Todd

Faculty Research & Creative Activity

Little is known about the reproductive biology of Stylisma pickeringii var. pattersonii, an endangered plant in Illinois occurring in only three counties (Cass, Henderson, and Mason). The objective of this study was to estimate flower densities and temporal (time of day and seasonal) differences in insect visitation to flowers of S. pickeringii in 2002 for native populations in Henderson and Mason Counties. A 50 m transect was located where S. pickeringii was most abundant and quadrats (0.25 m2) were placed on alternate sides of the tape measure at every meter at random distances from the transect. The number of flowers …


Behavioral Explanations Underlying The Lack Of Trap Effectiveness For Small-Scale Management Of Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Patrick C. Enstrom, Carissa A. Schoenick Jan 2009

Behavioral Explanations Underlying The Lack Of Trap Effectiveness For Small-Scale Management Of Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Patrick C. Enstrom, Carissa A. Schoenick

Faculty Research & Creative Activity

Traps containing a combination floral and synthetic pheromone lure are used to monitor and manage Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae). One key factor limiting trap effectiveness for beetle control is the "trap spillover" phenomenon, in which the trap attracts beetles without capturing them, resulting in increased damage to surrounding host plants. We investigated the mechanisms underlying trap spillover by conducting two studies in a soybean field in east central Illinois. In the first study, we set up trap stations for 1 d and compared the sex, size, and egg load (for females) of beetles caught in the traps …


Sucrose Phosphate Synthase Expression Influences Poplar Phenology, Thomas Canam, Ji-Young Park, Kyu-Young Kang, Faride Unda, Shawn D. Mansfield Jan 2009

Sucrose Phosphate Synthase Expression Influences Poplar Phenology, Thomas Canam, Ji-Young Park, Kyu-Young Kang, Faride Unda, Shawn D. Mansfield

Faculty Research & Creative Activity

The objective of this study was to manipulate the intracellular pools of sucrose, and investigate its role in regulating plant growth, phenology (leaf senescence and bud break) and fibre development. This objective was achieved by differentially expressing an Arabidopsis (Arabidopsis thaliana L. Heynh.) sucrose phosphate synthase (SPS) gene in hybrid poplar (Populus alba · Populus grandidentata Michx.), a model system for tree biology with substantial industrial relevance in the context of short rotation forestry and a target bioenergy crop. Phenotypic differences were evident in the transgenic trees, as both the timing of bud flush and leaf senescence were altered compared …

Vegetative Anatomy And Systematics Of Triphorinae (Orchidaceae), Barbara Carlsward, William Stern Jan 2009

Vegetative Anatomy And Systematics Of Triphorinae (Orchidaceae), Barbara Carlsward, William Stern

Faculty Research & Creative Activity

Triphorinae represents a group of three anatomically simple genera, the structural features of which are unspecialized. The anomocytic stomatal pattern occurs in all genera; it predominates in Triphora . A foliar hypodermis, sclerenchyma, fibre bundles and stegmata are absent. The mesophyll is homogeneous. The exodermal and endodermal cells in the roots are entirely thin-walled and tilosomes are absent. However, there are anatomical modifications that appear to be unique: root hairs in Monophyllorchis are borne on velamenal buttresses and, in Psilochilus , they arise endogenously. In the root vascular system of Psilochilus , the metaxylem occurs as a circumferential band. The …

The Legal Regime For The Arctic Ocean, Christopher C. Joyner Jan 2009

The Legal Regime For The Arctic Ocean, Christopher C. Joyner

Florida State University Journal of Transnational Law & Policy

With Arctic sea ice melting at rates faster than ever before, global climate change is opening up the polar region to increased navigation, exploration, and exploitation. The 'Arctic eight" nations have ignited a new competition for control of the trade routes and access to the rich deposits of resources that governments speculate might lie beneath the ice. In this article, the author explores the framework for a legal regime in the Arctic, identifying and critically assessing the agreements that govern the space, with the express intent of relating how they legally impact on human activities in the Arctic Ocean. It …


Protection Of Languages And Self-Expressions Under Islamic Law, Liaquat Ali Khan Jan 2009

Protection Of Languages And Self-Expressions Under Islamic Law, Liaquat Ali Khan

Florida State University Journal of Transnational Law & Policy

Islamic law recognizes two distinct divine rights, one applying to speech communities and the other to individuals. The divine right to language allows each speech community to preserve and celebrate its native language free of coercion and disrespect from other speech communities. Native languages are the assets of speech communities. Islamic law prohibits coercive degradation of native languages while at the same time it interposes no barriers in learning other languages. Closely related to the right to language is the divine right to individual self-expression or self-determination. Each human being is unique because God, the Master-Artist, shapes each human being …


Rhinoviruses: The Quest For A Cure, Michelle Gordon-Grunin Jan 2009

Rhinoviruses: The Quest For A Cure, Michelle Gordon-Grunin

The Science Journal of the Lander College of Arts and Sciences

Rhinoviruses, also known as Human Rhinovirus, abbreviated HRV, are one of the many causes of the common cold. In fact, around 50 percent of all cold are caused by rhinoviruses, with the other major candidates being coronaviruses, influenza A or B virus, and minor causative agents like parainfluenza virus, respiratory syncytial virus, adenovirus, and enterovirus (Makela and Puhakka, 1997). However, due to the complex molecular structure of rhinoviruses, a cure for the common cold caused by HRV is still in the making. Several new treatments have been discovered, impacting the virus as different stages of its life, hopefully to prevent …

Automatic Musical Meter Detection, Mikel Gainza Jan 2009

Automatic Musical Meter Detection, Mikel Gainza

Conference papers

A method that automatically estimates the metrical structure of a piece of music is presented. The approach is based on the generation of a beat similarity matrix, which provided information about the similarity between any two beats of a piece of music. The repetitive structure of most music is exploited by processing the beat similarity matrix in order to identify similar patterns of beats in different parts of a piece. This principles proves to be equally effective for the detection of both duple and triple meters as awll as complex meters. The use of beat positions and dynamic programming techniques …

First X-Ray Structural Characterisation Of Host-Guest Interactions In Tetra-Tetrazole Macrocycles, Fintan Kelleher, Andrew Bond, Adrienne Fleming, Jackie Gaire, John Mcginley, Vickie Mckee Jan 2009

First X-Ray Structural Characterisation Of Host-Guest Interactions In Tetra-Tetrazole Macrocycles, Fintan Kelleher, Andrew Bond, Adrienne Fleming, Jackie Gaire, John Mcginley, Vickie Mckee

Articles

The syntheses of tetra-tetrazole macrocycles, containing two 1,3-bis(tetrazole)benzene units linked by a variety of n-alkyl (n = 3, 5, 7 or 9 carbon atoms) chain lengths, are described. The crystal structures of two 1,3-bis(tetrazole)benzenes containing pendant bromoalkyl chains (n = 3 or 5) are reported. A tetra-tetrazole macrocycle has also been structurally characterised and contains an unexpected “host-guest” interaction through binding of a chloroform solvent molecule. The resulting deviation of the macrocycle from planarity results from a combination of the “host-guest” interaction and strong intermolecular interactions between adjacent tetrazole and phenylene rings.

Research In Bioenergy And Other Renewable Energy Sources In Bulgaria, Emilia Mihaylova, Anna Garo Aladjadjian Jan 2009

Research In Bioenergy And Other Renewable Energy Sources In Bulgaria, Emilia Mihaylova, Anna Garo Aladjadjian

Conference Papers

The interest in Renewable Energy Sources (RES) in Bulgaria reflects the changes in the field of energy policy worldwide and in Europe. The key to successful development of renewable energies in Bulgaria requires a combination of political commitment and decision making as well as support mechanisms including well-defined government targets, technological advances and public acceptance. The renewable energy sources (RES) theoretical potential in Bulgaria is considerable. It is evaluated to 14387 J/year for geothermal energy; 77156,7 J/year for solid agricultural waste; 478,4 J/year – biomass from paper waste; 9605,2 J/year –biomass from wood for heating; 79,8 J/year –biomass from natural …


Focusing On Process And History: Path Dependence, Paul Donnelly Jan 2009

Focusing On Process And History: Path Dependence, Paul Donnelly

Books/Book Chapters

In recognition of the calls for more processual and historically informed organizational theorizing, this chapter considers the notion of path dependency, an approach which holds that a historical path of choices has the character of a branching process with a self-reinforcing dynamic such that preceding steps in a particular direction induce further movement in the same direction, thereby making the possibility of switching to some other previously credible alternative more difficult. Path dependence seeks to assess how process, sequence and temporality can be best incorporated into explanation, the focus of the researcher being on particular outcomes, temporal sequencing and the …

Diet Of Pygmy Sperm Whales (Kogia Breviceps) In The Hawaiian Archipelago, Kristi West, William Walker, Robin Baird, Whitney White, Gregg Levine, Eric Brown, David Schofield Jan 2009

Diet Of Pygmy Sperm Whales (Kogia Breviceps) In The Hawaiian Archipelago, Kristi West, William Walker, Robin Baird, Whitney White, Gregg Levine, Eric Brown, David Schofield

United States Department of Commerce: Staff Publications

The biology and ecology of the pygmy sperm whale (Kogia breviceps) is poorly understood among odontocetes (McAlpine 2002). In Hawaiian waters, pygmy sperm whales are the second most frequently recorded stranded cetacean species, with 35 strandings documented between 1963 and 2008 (Shallenberger 1981, Nitta 1987, Maldini et al. 2005, NMFS database). Despite the high frequency of strandings, sightings of this species in Hawaiian waters are rare (Baird 2005). Given the low number of sightings, examination of stranded animals provides virtually the only means to study the biology and ecology of pygmy sperm whales in the area.


Treatment Of Northern Fur Seal (Callorhinus Ursinus) Pups With Ivermectin Reduces Hookworm-Induced Mortality, Robert Delong, Anthony Orr, Ryan Jenkinson, Eugene T. Lyons Jan 2009

Treatment Of Northern Fur Seal (Callorhinus Ursinus) Pups With Ivermectin Reduces Hookworm-Induced Mortality, Robert Delong, Anthony Orr, Ryan Jenkinson, Eugene T. Lyons

United States Department of Commerce: Staff Publications

A breeding population of approximately 8,000–10,000 northern fur seals (Callorhinus ursinus) is located at San Miguel Island in the California Channel Islands. The population is increasing and produces about 2,500 pups annually (Melin et al. 2008). Pup mortality has increased during the past 10 yr and has reached 50% or more in some recent years. Although we have not completed studies to describe the causes of this pup mortality, it appears that hookworm disease has been a major cause (Lyons et al. 2001).


An Hsus Report: The Impact Of Industrialized Animal Agriculture On World Hunger, The Humane Society Of The United States Jan 2009

An Hsus Report: The Impact Of Industrialized Animal Agriculture On World Hunger, The Humane Society Of The United States

Impact of Animal Agriculture

Of the world’s nearly 6.8 billion humans, almost 1 billion people are malnourished. Feeding half the world’s grain crop to animals raised for meat, eggs, and milk instead of directly to humans is a significant waste of natural resources, including fossil fuels, water, and land. Raising animals for food is also a major contributor to global warming, which is expected to further worsen food security globally. To meet the daily nutritional needs of a rapidly expanding population, the world’s human community, particularly in Western countries, must reduce its reliance on animal products and shift to a more plant-based diet.
