Controlled De-Cross-Linking And Disentanglement Of Feather Keratin For Fiber Preparation Via A Novel Process, Helan Xu, Yiqi Yang

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Pure protein fibers were fabricated from chicken feathers via a potentially green process. In the last several decades, efforts have been made to produce keratin-based industrial products, especially fibers. However, the methods of producing keratin fibers directly from chicken feathers could not be repeated. In this research, protein fibers from chicken feathers were developed using chemicals that could be either derived from renewable resources or facilely recycled. Backbones of keratin were preserved after cleavage of disulfide bonds using cysteine. Sodium dodecyl sulfate (SDS) was applied to dissolve keratin for spinning. Increasing SDS concentration intensified the ordered conformation of keratin, first …

Introduction [To Automation: The Future Of Weed Control In Cropping Systems]: Scope Of The Problem—Rising Costs And Demand For Environmental Safety For Weed Control, Stephen L. Young, Francis J. Pierce, Pete Nowak

West Central Research and Extension Center, North Platte

Many organic and conventional producers rank weed control as their number one production cost. For organic producers particularly, weed control has become increasingly important as organic production has increased its market share. In conventional systems, herbicide resistance, off-target movement, and increased regulations have left many growers with few alternatives. Added to this is an increasing demand from the public for a safer and more sustainable supply of food. This chapter addresses the problems of mechanized agricultural systems to set the stage for the introduction and adoption of more advanced technology to meet the needs of growers and satisfy the desires …

Characterization Of Management And Environmental Factors Associated With Regional Variations In Potato Zebra Chip Occurrence, F. Workneh, D. C. Henne, J. A. Goolsby, J. M. Crosslin, S. D. Whipple, J. D. Bradshaw, A. Rashed, L. Paetzold, R. M. Harveson, C. M. Rush

Panhandle Research and Extension Center

Potato zebra chip (ZC), caused by the bacterial pathogen ‘Candidatus

Liberibacter solanacearum’, which is vectored by the potato psyllid

(Bactericera cockerelli), has caused widespread damage to U.S. potato

production ever since its first discovery in south Texas in 2000. To

determine the influence of environmental factors and management

practices on ZC occurrence, data on management and meteorological

variables, field locations, and psyllid counts were collected over a 3-year

period (2010 to 2012) from six locations across the central United States

(south Texas to Nebraska). At these locations, ZC-symptomatic plants

were counted in 26 fields from systematically established …

Future Directions For Automated Weed Management In Precision Agriculture, Stephen L. Young, George Meyer, Wayne Woldt

West Central Research and Extension Center, North Platte

In cropping systems, integrated weed management is based on diversification. Rather than relying solely on one or two herbicides, a multiplicity of weed control strategies is employed. Yet, integrated weed management as currently practiced is far from integrated; every weed is still managed the same regardless of location or season. The recent development of precision application technology is now allowing for smaller treatment units by making applications according to site- specific demands. The automated systems of the future will have sensor and computer technologies that first categorize each and every plant in the field as either weed or crop and …

Root Growth Of Two Perennial Grass Types And Musk Thistle (Carduus Nutans) In Temperate Grasslands Of North America, Chengchou Han, Stephen L. Young

West Central Research and Extension Center, North Platte

Root architecture of prairie grasslands, which depends on plant phenology and edaphic conditions, strongly influences susceptibility to invasion by nonindigenous plant species. Field studies were conducted to compare in situ root growth patterns of warm-season (WS) and cool-season (CS) perennial grasses and musk thistle during a 2-yr period that included a drought in the second year. In 2 yr, CS grasses had the highest amount of roots (1,296 m roots m^–2 [395 ft roots ft^–2]) across shallow (0 to 28 cm [0 to 11 in.]), medium (28 to 56 cm), and deep (56 to 98 cm) depths …

Bioeconomic Factors Of Beef Heifer Maturity To Consider When Establishing Criteria To Optimally Select And/Or Retain Herd Replacements, M. C. Stockton, R. K. Wilson, D. M. Feuz, L. A. Stalker, R. N. Funston

West Central Research and Extension Center, North Platte

Understanding the biology of heifer maturity and its relationship to calving difficulty and subsequent breeding success is a vital step in building a bioeconomic model to identify optimal production and profitability. A limited dependent variable probit model is used to quantify the responses among heifer maturities, measured by a maturity index (MI), on dystocia and second pregnancy. The MI account for heifer age, birth BW, prebreeding BW, nutrition level, and dam size and age and is found to be inversely related to dystocia occurrence. On average there is a 2.2% increase in the probability of dystocia with every 1 point …

Utilizing A Preplant Soil Test For Predicting And Estimating Root Rot Severity In Sugar Beet In The Central High Plains Of The United States, R. M. Harveson, K. A. Nielsen, Kent M. Eskridge

Panhandle Research and Extension Center

Aphanomyces cochlioides and Rhizoctonia solani are important soilborne

pathogens causing root diseases that are primary constraints to

sugar beet production in Nebraska, Colorado, and Wyoming. These

types of diseases are difficult to control because they are often not

noticed until substantial damage has already occurred. Efforts to manage

them would be more effective if techniques were available that

were more predictive than reactive. Therefore, a preplant soil test was

developed to estimate the relative pathogen populations in the soil and

to predict potential root disease problems later in the growing season.

Preplant soil samples collected from fields to be sown …

Edible Grain Legumes, George J. Vandemark, Mark A. Brick, Juan M. Osorno, James D. Kelly, Carlos A. Urrea

Panhandle Research and Extension Center

Edible grain legumes, including dry bean (Phaseolus vulgaris L.), dry pea (Pisum sativum L.), chickpea (Cicer arientinum L.), and lentil (Lens culinaris Medikus), have served as important sources of protein in the human diet for thousands of years. In the United States, these crops are consumed nationally and produced for export markets. The objectives of this study were to examine yield gains in edible grain legume crops over the past 25 yr. Genetic gain in dry bean during the past 30 yr based on common trials was 13.9 kg ha⁻¹ yr⁻¹ (0.77% yr …

A Phylogenetic Model For Understanding The Effect Of Gene Duplication On Cancer Progression, Qin Ma, Jaxk H. Reeves, David A. Liberles, Lili Yu, Zheng Chang, Jing Zhao, Juan Cui, Ying Xu, Liang Liu

School of Computing: Faculty Publications

As biotechnology advances rapidly, a tremendous amount of cancer genetic data has become available, providing an unprecedented opportunity for understanding the genetic mechanisms of cancer. To understand the effects of duplications and deletions on cancer progression, two genomes (normal and tumor) were sequenced from each of five stomach cancer patients in different stages (I, II, III and IV). We developed a phylogenetic model for analyzing stomach cancer data. The model assumes that duplication and deletion occur in accordance with a continuous time Markov Chain along the branches of a phylogenetic tree attached with five extended branches leading to the tumor …

Bayesian Network Prior: Network Analysis Of Biological Data Using External Knowledge, Senol Isci, Haluk Dogan, Cengizhan Ozturk, Hasan H. Otu

Department of Electrical and Computer Engineering: Faculty Publications

Motivation: Reverse engineering GI networks from experimental data is a challenging task due to the complex nature of the networks and the noise inherent in the data. One way to overcome these hurdles would be incorporating the vast amounts of external biological knowledge when building interaction networks. We propose a framework where GI networks are learned from experimental data using Bayesian networks (BNs) and the incorporation of external knowledge is also done via a BN that we call Bayesian Network Prior (BNP). BNP depicts the relation between various evidence types that contribute to the event ‘gene interaction’ and is used …

Development Of A Fatal Noncompressible Truncal Hemorrhage Model With Combined Hepatic And Portal Venous Injury In Normothermic Normovolemic Swine, Ujwal R. Yanala, Jason M. Johanning, Iraklis I. Pipinos, Gustavo F. Larsen, William H. Velander, Mark A. Carlson

Department of Chemical and Biomolecular Engineering: Faculty Publications

Noncompressible truncal hemorrhage and brain injury currently account for most early mortality of warfighters on the battlefield. There is no effective treatment for noncompressible truncal hemorrhage, other than rapid evacuation to a surgical facility. The availability of an effective field treatment for noncompressible truncal hemorrhage could increase the number of warfighters salvaged from this frequently-lethal scenario. Our intent was to develop a porcine model of noncompressible truncal hemorrhage with a ,50% one-hour mortality so that we could develop new treatments for this difficult problem. Normovolemic normothermic domestic swine (barrows, 3 months old, 34–36 kg) underwent one of three injury types …

Democratic Deliberation And The Ethical Review Of Human Subjects Research, Govind Persad

Sturm College of Law: Faculty Scholarship

In the United States, the Presidential Commission for the Study of Bioethical Issues has proposed deliberative democracy as an approach for dealing with ethical issues surrounding synthetic biology. Deliberative democracy might similarly help us as we update the regulation of human subjects research. This paper considers how the values that deliberative democratic engagement aims to realize can be realized in a human subjects research context. Deliberative democracy is characterized by an ongoing exchange of ideas between participants, and an effort to justify decisions that bind participants by appeal to reasons that the participants can understand and share. Even when unanimous …

The Hidden Rise Of Efficient (De)Listing, Zachary A. Bray

Law Faculty Scholarly Articles

What is the value of the gray wolf, and what might be the costs of including a tiny desert lizard on the list of endangered species? For decades, Congress has formally excluded questions about the economic value of species and the costs of their protection from agency decisions about whether a species should be listed under the Endangered Species Act. Recently, however, a number of federal legislators have sought to incorporate their own ad hoc views about the value of individual species in peril, and the costs of protecting such species, into listing decisions. This goal has been accomplished through …

Proselytism And The Right To Freedom From Improper Irreligious Influence: The Example Of Public School Education, S De Freitas

Law Papers and Journal Articles

Jurisprudentially speaking, "proselytism" is a concept within the larger genus of the protection of religious rights and freedoms. The word lends itself to differing opinions. However, there is a popular school of thought that "proselytism" has to do only with influencing people to adopt a particular religion. Such an understanding relies on the view that only the "religious" can be insidious and bear the potential to improperly proselytise, and thus excludes the possibility of improper irreligious forms of influence. In referring to the example of public-school education, it is argued that as much as the religious has the potential for …

You Are What You Eat, Or Are You? The Challenges Of Translating High-Fat-Fed Rodents To Human Obesity And Diabetes, M. Lai, P. C. Chandrasekera, Neal D. Barnard

Medicine Faculty Publications

Obesity and type 2 diabetes mellitus (T2DM) are rapidly growing worldwide epidemics with major health consequences. Various human-based studies have confirmed that both genetic and environmental factors (particularly high-caloric diets and sedentary lifestyle) greatly contribute to human T2DM. Interactions between obesity, insulin resistance and β-cell dysfunction result in human T2DM, but the mechanisms regulating the interplay among these impairments remain unclear. Rodent models of high-fat diet (HFD)-induced obesity have been used widely to study human obesity and T2DM. With >9000 publications on PubMed over the past decade alone, many aspects of rodent T2DM have been elucidated; however, correlation to human …

Meat Consumption As A Risk Factor For Type 2 Diabetes, Neal D. Barnard, Susan Levin, Caroline Trapp

Medicine Faculty Publications

Disease risk factors identified in epidemiological studies serve as important public health tools, helping clinicians identify individuals who may benefit from more aggressive screening or risk-modification procedures, allowing policymakers to prioritize intervention programs, and encouraging at-risk individuals to modify behavior and improve their health. These factors have been based primarily on evidence from cross-sectional and prospective studies, as most do not lend themselves to randomized trials. While some risk factors are not modifiable, eating habits are subject to change through both individual action and broader policy initiatives. Meat consumption has been frequently investigated as a variable associated with diabetes risk, …

Dysferlin Regulates Cell Membrane Repair By Facilitating Injury-Triggered Acid Sphingomyelinase Secretion, Aurelia Defour, Jack H. Van Der Meulen, Rujuta R. Bhatt, Anne Bigot, R. Bashir, Kanneboyina Nagaraju, Jyoti K. Jaiswal

Genomics and Precision Medicine Faculty Publications

Dysferlin deficiency compromises the repair of injured muscle, but the underlying cellular mechanism remains elusive. To study this phenomenon, we have developed mouse and human myoblast models for dysferlinopathy. These dysferlinopathic myoblasts undergo normal differentiation but have a deficit in their ability to repair focal injury to their cell membrane. Imaging cells undergoing repair showed that dysferlin-deficit decreased the number of lysosomes present at the cell membrane, resulting in a delay and reduction in injury-triggered lysosomal exocytosis. We find repair of injured cells does not involve formation of intracellular membrane patch through lysosome–lysosome fusion; instead, individual lysosomes fuse with the …

Knowledge-Fused Differential Dependency Network Models For Detecting Significant Rewiring In Biological Networks, Ye Tian, Bai Zhang, Eric P. Hoffman, Robert Clarke, Zhen Zhang, Ie-Ming Shih, Jianhua Xuan, David M. Herrington, Yue Wang

Genomics and Precision Medicine Faculty Publications

Background

Modeling biological networks serves as both a major goal and an effective tool of systems biology in studying mechanisms that orchestrate the activities of gene products in cells. Biological networks are context-specific and dynamic in nature. To systematically characterize the selectively activated regulatory components and mechanisms, modeling tools must be able to effectively distinguish significant rewiring from random background fluctuations. While differential networks cannot be constructed by existing knowledge alone, novel incorporation of prior knowledge into data-driven approaches can improve the robustness and biological relevance of network inference. However, the major unresolved roadblocks include: big solution space but a …

Non-Invasive Mri And Spectroscopy Of Mdx Mice Reveal Temporal Changes In Dystrophic Muscle Imaging And In Energy Deficits., Christopher R. Heier, Alfredo D.

Genomics and Precision Medicine Faculty Publications

In Duchenne muscular dystrophy (DMD), a genetic disruption of dystrophin protein expression results in repeated muscle injury and chronic inflammation. Magnetic resonance imaging shows promise as a surrogate outcome measure in both DMD and rehabilitation medicine that is capable of predicting clinical benefit years in advance of functional outcome measures. The mdx mouse reproduces the dystrophin deficiency that causes DMD and is routinely used for preclinical drug testing. There is a need to develop sensitive, non-invasive outcome measures in the mdx model that can be readily translatable to human clinical trials. Here we report the use of magnetic resonance imaging …
