Isolation Of Mycobacterium Avium Subspecies Paratuberculosis Reactive Cd4 T Cells From Intestinal Biopsies Of Crohn’S Disease Patients, Ingrid Olsen, Stig Tollefsen, Claus Aagaard, Liv J. Reitan, J. P. Bannantine, Peter Andersen, Ludvig M. Sollid, Knut E.A. Lundin

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

Background: Crohn’s disease (CD) is a chronic granulomatous inflammation of the intestine. The etiology is unknown, but an excessive immune response to bacteria in genetically susceptible individuals is probably involved. The response is characterized by a strong Th1/Th17 response, but the relative importance of the various bacteria is not known.

Methodology/Principal Findings: In an attempt to address this issue, we made T-cell lines from intestinal biopsies of patients with CD (n = 11), ulcerative colitis (UC) (n = 13) and controls (n = 10). The T-cell lines were tested for responses to various bacteria. A majority of the CD patients …

The Expansion And Diversification Of The Export Sector And Economic Growth: The Costa Rican Experience, Gustavo Filipe Canle Ferreira

LSU Doctoral Dissertations

A large body of empirical literature has investigated the linkages between exports and output. Nevertheless, empirical evidence remains inconclusive and the topic remains open to discussion. Additionally, a number of studies have examined the positive effects that export diversification may have on economic growth. Within the Latin America region, Costa Rica has been lauded for its long democratic tradition, relative economic stability, and for evolving from being a small economy heavily reliant on exports of coffee and bananas, to become the largest software exporter per capita in Latin America. This study examined the impact that the expansion and diversification of …

Plan To Support Grains Industry Development 2009-2012, Department Of Agriculture And Food, Western Australia

Grain and other field crops published reports

The Plan to Support Grains Industry Development (‘the Plan’) recognises that Western Australian agricultural industries are integral to the economic wellbeing of regional and rural communities. The Plan promotes a progressive and profitable grains industry through modern best practice services and research to enhance continuous improvement in farming and supply chain practices.

The Plan has been developed to align with the Government of Western Australia’s initiatives, strategies and tactics for ‘making every hectare count’ (see Appendix 1) and with grains industry needs as identified by industry stakeholders during a series of consultation forums. These industry needs will be addressed in …

My View: Automated Weed Control In Organic Cropping Systems, Stephen L. Young

West Central Research and Extension Center, North Platte

In 2005, for the first time, all 50 states in the United States had some certified organic farmland (USDA 2007). Producers in the United States dedicated over 1.62 million hectares of farmland to organic production systems in 2005. The increase in the number of hectares of crops being grown organically has brought with it a growing need for more labor and nonconventional inputs for weed control. Currently, weed control is ranked as the number one production cost by organic and many conventional growers. Over the past 10 yr, development of machine-guided technologies for site-specific (precision) weed control has advanced rapidly, …

Functionally Similar Species Confer Greater Resistance To Invasion: Implications For Grassland Restoration, Stephen L. Young, Jacob N. Barney, Guy B. Kyser, Tracy S. Jones, Joseph M. Ditomaso

West Central Research and Extension Center, North Platte

Plant community functional composition can be manipulated in restored ecosystems to reduce the establishment potential of invading species. This study was designed to compare invasion resistance among communities with species functionally similar or dissimilar to yellow starthistle (Centaurea solstitialis), a late-season annual. A field experiment was conducted in the Central Valley of California with six experimental plant communities that included (1) six early-season native annual forbs (AF); (2) five late-season native perennials and one summer annual forb (NP); (3) a combination of three early-season native annual forbs and three late-season native perennials (FP); (4) six early-season non-native annual …

The Importance Of Nutrition Label Usage In The Context Of Obesity: A Cross-Country Study Of The Usa And Turkey, Emine Bayar

University of Kentucky Master's Theses

Obesity, the second leading cause of preventable death in the U.S., and related health problems increase people’s concerns about healthy food consumption. The increased prevalence of obesity is a major concern of societies both in developed and developing countries. Nutrition label usage has been increasing due to the link between diet and health. This study intends to provide a framework for describing profiles of consumers who are more likely to use nutrition labels in USA and Turkey, a developing country with increasing obesity rates in recent years. Empirical results present similarities and differences between consumers’ attributes for food label usage …
