Science-Based Organic Farming 2006: Toward Local And Secure Food Systems, Charles A. Francis, Katja Koehler-Cole, Twyla Hansen, Peter Skelton

Publications from the Center for Applied Rural Innovation (CARI)

Organic farming includes growing food and fiber—animals, agronomic crops, horticultural fruits and vegetables, related products—as one dynamic and rapidly evolving component of our complex U.S. food system. Even as more farmers are moving toward organic certification and participation in an environmentally sound and economically lucrative market, questions arise about the long-term social impacts and sustainability of a set of practices that has gone from a movement to an industry. Consolidations in the organic trade have brought multinational corporations to the table, as they have observed a grassroots activity that has grown by 20% per year for the past two decades, …

The Effect Of Handling Time On Temporal Discounting In Two New World Primates, Alexandra G. Rosati, Jeffrey R. Stevens, Marc D. Hauser

Center for Brain, Biology, and Behavior: Faculty Publications

Foraging decisions in nonhuman animals often require choosing between small, immediate food rewards and larger, more delayed rewards. Faced with such choices, animals typically discount or devalue the future quite strongly. Although discounting studies often focus on delays to reward access, other temporal intervals contribute to foraging rate, and thus may potentially influence discounting levels. Here, we examine the effect of handling time, the time required to process and consume food, on discounting in cottontop tamarins, Saguinus oedipus, and common marmosets, Callithrix jacchus, two species that differ in levels of temporal discounting. We presented subjects with a discounting task under …

Endothelial Cell Cortactin Phosphorylation By Src Contributes To Polymorphonuclear Leukocyte Transmigration In Vitro, L. Yang, Jennifer R. Kowalski, X. Zhan, S. M. Thomas, F. W. Luscinskas

Scholarship and Professional Work - LAS

The underlying mechanisms that regulate leukocyte transendothelial migration through the vascular endothelium remain unclear. Cortactin is a substrate of Src tyrosine kinases and a regulator of cytoskeletal dynamics. Previous studies demonstrated a role for Src phosphorylation of cortactin in clustering of E-selectin and intercellular cell adhesion molecule-1 around adherent leukocytes. In the current study, we used an in vitro flow model to investigate the role of Src-induced cortactin phosphorylation in endothelium during polymorphonuclear leukocyte (PMN) transmigration through human umbilical vein endothelium (HUVEC) monolayers preactivated with tumor necrosis factor-{alpha}. Inhibition of Src in HUVEC using Src kinase inhibitors PP2 and SU6656 …

Meaningful Labeling Of Integrated Query Interfaces, Eduard Dragut, Clement Yu, Weiyi Meng

Cyber Center Publications

The contents of Web databases are accessed through queries formulated on complex user interfaces. In many domains of interest (e.g. Auto) users are interested in obtaining information from alternative sources. Thus, they have to access many individual Web databases via query interfaces. We aim to construct automatically a well-designed query interface that integrates a set of interfaces in the same domain. This will permit users to access information uniformly from multiple sources. Earlier research in this area includes matching attributes across multiple query interfaces in the same domain and grouping related attributes. In this paper, we investigate the naming of …

Stromal Haze, Myofibroblasts, And Surface Irregularity After Prk, Marcelo V. Netto, Rajiv R. Mohan, Sunilima Sinha, Ajay Sharma, William Dupps, Steven E. Wilson

Pharmacy Faculty Articles and Research

The aim of this study was to investigate the relationship between the level of stromal surface irregularity after photorefractive keratectomy (PRK) and myofibroblast generation along with the development of corneal haze.

Variable levels of stromal surface irregularity were generated in rabbit corneas by positioning a fine mesh screen in the path of excimer laser during ablation for a variable percentage of the terminal pulses of the treatment for myopia that does not otherwise generate significant opacity. Ninety-six rabbits were divided into eight groups[.]

Slit lamp analysis and haze grading were performed in all groups. Rabbits were sacrificed at 4 hr …

Hahn, Bette T. Korber, Feng Gao, Barton F. Haynes

Nebraska Center for Virology: Faculty Publications

HIV-1 subtype C is the most common HIV-1 group M subtype in Africa and many parts of Asia. However, to date HIV-1 vaccine candidate immunogens have not induced potent and broadly neutralizing antibodies against subtype C primary isolates. We have used a centralized gene strategy to address HIV-1 diversity, and generated a group M consensus envelope gene with shortened consensus variable loops (CON-S) for comparative studies with wildtype (WT) Env immunogens. Our results indicate that the consensus HIV-1 group M CON-S Env elicited cross-subtype neutralizing antibodies of similar or greater breadth and titer than the WT Envs tested, indicating the …

Methods For The Study Of Signaling Molecules In Membrane Lipid Rafts And Caveolae, Rennolds S. Ostrom, Paul A. Insel

Pharmacy Faculty Articles and Research

Lipid rafts and caveolae are cholesterol- and sphingolipid-rich microdomains of the plasma membrane that concentrate components of certain signal transduction pathways. Interest in and exploration of these microdomains has grown in recent years, especially after the discovery of the biochemical marker of caveolae, caveolin, and the recognition that caveolin interacts with many different signaling molecules via its scaffolding domain. There are three major types of caveolins (1, 2, and 3), with some selectivity in their expression in different tissues. Results assessing lipid raft/caveolae co-localization of molecules in signal transduction pathways have provided support for the idea that signaling components are …

Effect Of A Single Bout Of Prior Moderate Exercise On Cutaneous Perfusion In Type 2 Diabetes, Sheri R. Colberg, Henri K. Parson, Tanja Nunnold, D. Robb Holton, Aaron I. Vinik

Human Movement Studies & Special Education Faculty Publications

In diabetic individuals, increased shunting of circulation away from the skin may exist, contributing to their greater risk for ulcerations and poor cutaneous healing. In a prospective study (1), we previously found a lower skin perfusion during local heating in the foot dorsum of sedentary type 2 diabetic individuals compared with active people without diabetes. This defect was present despite normal increases in skin interstitial nitric oxide (NO), suggesting that NO is either ineffective or not involved (2). A prior bout of maximal exercise also lessened the impaired responsiveness to local heating of the dorsal foot in active type 2 …

Calving And Preweaning Growth Performance Traits Of Calves Sired By Charolais, Simmental And Eastern Anatolian Red Bulls, Abdülkadi̇r Özlütürk, Mete Yanar, Naci̇ Tüzemen, Si̇nan Kopuzlu

Turkish Journal of Veterinary & Animal Sciences

Charolais (C)-, Simmental (S)-, and Eastern Anatolian Red (EAR)-sired calves born in 2 locations in Eastern Anatolia were compared in terms of calving traits and preweaning growth characteristics. Breed of sire effects were significant (P < 0.01) for birth weight, 205-day weaning weight, average daily weight gain from birth to weaning, and some body measurements at birth. S- and C-sired calves were heavier at birth and larger for most body measurements at birth than EAR-sired calves. The C- and S-sired calves also had higher 205-day weight than the EAR-sired calves. Although the level of calving difficulty was higher in the S and C crosses, the differences were not statistically significant. Male calves had significantly (P < 0.01) heavier birth and 205-day weights, higher preweaning average daily gain and greater body measurements (e.g., height at withers, heart girth and cannon bone girth) than females. Location differences were also significant (P < 0.01) for survival rate from birth to weaning, preweaning growth rate and 205-day weight. In conclusion, although C- and S-sired calves performed similarly for most traits, all parameters of the preweaning growth were higher in calves sired by S and C bulls than in calves sired by EAR bulls. Therefore, both C and S could be considered as sire breeds for crossbreeding programs to be implemented in Eastern Anatolia, since these breeds did not cause an adverse influence on the calving and growth traits of the crossbred calves.

Combining Linear Regression With Reconstructability Analysis: A Study Of Differences In Health Status, Renato Carletti, Martin Zwick

Complex Systems Faculty Publications and Presentations

A linear regression model was used to predict variations in health status with the hypothesis that literacy level as a proximal measure for educational attainment would show a strong correlation with health status. Groups of other independent variables have also been introduced in the model to test whether the effect of literacy on health would have been mediated by other factors, or increased by them. The linear regression model did not show any strong relation between literacy and health, but pointed to other factors as predictors of health status.

Methods of data mining have been used for exploring throughout all …

The Speciation Of Metals In Mammals Influences Their Toxicokinetics And Toxicodynamics And Therefore Human Health Risk Assessment, Robert A. Yokel, Stephen M. Lasley, David C. Dorman

Pharmaceutical Sciences Faculty Publications

Chemical form (i.e., species) can influence metal toxicokinetics and toxicodynamics and should be considered to improve human health risk assessment. Factors that influence metal speciation (and examples) include: (1) carrier-mediated processes for specific metal species (arsenic, chromium, lead and manganese), (2) valence state (arsenic, chromium, manganese and mercury), (3) particle size (lead and manganese), (4) the nature of metal binding ligands (aluminum, arsenic, chromium, lead, and manganese), (5) whether the metal is an organic versus inorganic species (arsenic, lead, and mercury), and (6) biotransformation of metal species (aluminum, arsenic, chromium, lead, manganese and mercury). The influence of speciation on metal …

Transposon Disruption Of The Complex I Nadh Oxidoreductase Gene (Snod) In Staphylococcus Aureus Is Associated With Reduced Susceptibility To The Microbicidal Activity Of Thrombin-Induced Platelet Microbicidal Protein 1, Arnold S. Bayer, Peter Mcnamara, Michael R. Yeaman, Natalie Lucindo, Tiffanny Jones, Ambrose L. Cheung

Dartmouth Scholarship

The cationic molecule thrombin-induced platelet microbicidal protein 1 (tPMP-1) exerts potent activity against Staphylococcus aureus. We previously reported that a Tn551 S. aureus transposon mutant, ISP479R, and two bacteriophage back-transductants, TxA and TxB, exhibit reduced in vitro susceptibility to tPMP-1 (tPMP-1(r)) compared to the parental strain, ISP479C (V. Dhawan, M. R. Yeaman, A. L. Cheung, E. Kim, P. M. Sullam, and A. S. Bayer, Infect. Immun. 65:3293-3299, 1997). In the current study, the genetic basis for tPMP-1(r) in these mutants was identified. GenBank homology searches using sequence corresponding to chromosomal DNA flanking Tn551 mutant strains showed that the fourth gene …

Department of Public Health Scholarship and Creative Works

This field experiment examined the impact of an individual's need for cognition (NFC; the tendency to enjoy thinking deeply about issues), complex versus simple messages, and the interaction of NFC and message type on encouraging fruit and vegetable consumption. Callers to the Cancer Information Service of the National Cancer Institute (N = 517) were asked to participate in the experiment at the end of their call. Individual NFC was assessed, and participants were assigned randomly to receive a telephone message promoting fruit and vegetable consumption that was either complex and multifaceted or simple and straightforward. Similarly constructed brochures were mailed …

Never Let Me Clone? Countering An Ethical Argument Against The Reproductive Cloning Of Humans, Yvette Pearson

Philosophy Faculty Publications

In the March 2006 issue of EMBO reports, Christof Tannert, a bioethicist at the Max Delbrück Research Centre in Berlin, Germany, presented a moral argument against human reproductive cloning on the basis of Immanuel Kant’s categorical imperative (Tannert, 2006). In this article, I address some problems with Tannert’s views and show that our concerns about this prospective procedure should prompt us to scrutinize carefully the conventional procreative practices and attitudes. Indeed, if we set aside objections that are grounded in genetic determinism, many of the offensive features of human cloning are identical to problems with procreation by more conventional means, …

The Effects Of Red Pepper, Marigold Flower, And Synthetic Astaxanthin On Pigmentation, Growth, And Proximate Composition Of Penaeus Semisulcatus, Mustafa Göçer, Mahmut Yanar, Meti̇n Kumlu, Yasemen Yanar

Turkish Journal of Veterinary & Animal Sciences

Shrimps with an initial weight of 11.10 ± 0.26 g were fed diets supplemented with 6.6% red pepper (RP), 2.4% marigold flower (MF), and 100 mg/kg synthetic astaxanthin (SA), each of which contained 100 mg/kg total carotenoid, and a control diet (BD), without carotenoid supplement for 60 days. Dietary carotenoid sources did not significantly affect the growth of the shrimps (P > 0.05). SA supplementation yielded the highest survival rate (92%), followed by RP (82%) and the other diets (75%) (P < 0.05). All dietary carotenoid sources provided higher carotenoid accumulation compared to the control group (P < 0.05), but the difference between them was not significant (P > 0.05). RP and SA resulted in a greater protein increase in shrimp muscle than MF (P < 0.05); however, lipid, ash, and water content were similar in all diet groups (P > 0.05).
