The Use Of Argumentation In Socio-Scientific Issues: Enhancing Evolutionary Biology Instruction, Heath R. Marchand

Education and Human Development Master's Theses

With the adoption of the Next Generation Science Standards (NGSS), further emphasis in science education is being placed on preparing students to become more informed voters regarding social, ethical, economic and political topics that affect contemporary society. Parallel to this shift is a stronger emphasis on integrating evolutionary theory as a unifying concept in the biological sciences. Given that evolution is one of the aforementioned topics commonly discussed and debated about in social and political arenas, ensuring that instruction provides students from all backgrounds a comprehensive understanding of its principals is becoming increasingly important in contemporary science education.

Faculty Publications in Food Science and Technology

A prototype on-line acousto-optic tunable filter (AOTF)-based hyperspectral image acquisition system (λ = 450– 900 nm) was developed for tenderness assessment of beef carcasses. Hyperspectral images of ribeye muscle on stationary hanging beef carcasses (n = 338) at 2-day postmortem were acquired in commercial beef slaughter or packing plants. After image acquisition, a strip steak was cut from each carcass, vacuum packaged, aged for 14 days, cooked, and slice shear force tenderness scores were collected by an independent lab. Beef hyperspectral images were mosaicked together and principal component (PC) analysis was conducted to reduce the spectral dimension. Six different textural feature ...

Quantifying Land Cover Change Due To Petroleum Exploration And Production In The Haynesville Shale Region Using Remote Sensing, Daniel Unger, I-Kuai Hung, Kenneth W. Farrish, Darinda Dans

Faculty Publications

The Haynesville Shale lies under areas of Louisiana and Texas and is one of the largest gas plays in the U.S. Encompassing approximately 2.9 million ha, this area has been subject to intensive exploration for oil and gas, while over 90% of it has traditionally been used for forestry and agriculture. In order to detect the landscape change in the past few decades, Landsat Thematic Mapper (TM) imagery for six years (1984, 1989, 1994, 2000, 2006, and 2011) was acquired. Unsupervised classifications were performed to classify each image into four cover types: agriculture, forest, well pad, and other ...


Cell Viability Assessment Using The Alamar Blue Assay: A Comparison Of 2d And 3d Cell Culture Models, Franck Bonnier, Mark Keating, Tomasz P. Wrobel, Katarsyna Majzner, Malgorzata Baranska, Amaya Garcia, Alfonso Blanco, Hugh J. Byrne 2015 Dublin Institute of Technology

Cell Viability Assessment Using The Alamar Blue Assay: A Comparison Of 2d And 3d Cell Culture Models, Franck Bonnier, Mark Keating, Tomasz P. Wrobel, Katarsyna Majzner, Malgorzata Baranska, Amaya Garcia, Alfonso Blanco, Hugh J. Byrne

Articles

Comparisons of 2D and 3D cell culture models in literature have indicated differences in cellular morphology and metabolism, commonly attributed the better representation of in vivo conditions of the latter cell culture environment. Thus, interest in the use of 3D collagen gels for in vitro analysis has been growing. Although comparative studies to date have indicated an enhanced resistance of cells on collagen matrices against different toxicants, in the present study it is demonstrated that non-adapted protocols can lead to misinterpretation of results obtained from classical colorometric dye-based cytotoxic assays. Using the well established Alamar Blue assay, the ...

Beef tenderness is the most important trait affecting consumer beef eating satisfaction. Cuts from muscles with superior tenderness (tenderloin, ribeye, striploin) are consequently most highly valued, but because of recent record-high beef prices, the need to identify more economical cuts that will meet consumer expectations for tenderness is greater than ever. The eye of round (Semitendinosus) has traditionally been marketed as a lower-value cut, primarily owing to its inherent toughness. Tenderness improves throughout postmortem aging and continues to improve in muscles aged for greater than 35 days. Retail steaks from the Semitendinosus receive, on average, 17 days of aging, with ...


Effects Of Growth-Promoting Technologies On Muscle Structural Characteristics And Meat Tenderness, S. M. Ebarb, J. S. Drouillard, K. J. Phelps, J. A. Noel, M. A. Vaughn, D. D. Burnett, J. M. Gonzalez 2015 Kansas State University

Effects Of Growth-Promoting Technologies On Muscle Structural Characteristics And Meat Tenderness, S. M. Ebarb, J. S. Drouillard, K. J. Phelps, J. A. Noel, M. A. Vaughn, D. D. Burnett, J. M. Gonzalez

Kansas Agricultural Experiment Station Research Reports

Skeletal muscle tissue consists of two main structures that elicit strong influences on cooked meat tenderness: myofibrillar and connective tissues. The myofibrillar component consists of contractile and cytoskeletal proteins that aid in muscle contraction and support. A large portion of meat science literature documents the effects that postmortem aging elicits in terms of weakening the myofibrillar component to improve tenderness. Connective tissue is primarily comprised of collagen, the most abundant protein within the body. The function of this tissue is to support the myofibrillar component and transfer the force of contraction. Collagen, characterized by its solubility, is most commonly identified ...

The use of growth-promoting technologies has become a common practice in the beef cattle industry as producers strive for efficient growth and greater lean deposition. Two common technologies include exogenous hormonal implants and beta-adrenergic agonists (β-AA). Combination implants containing estrogen and testosterone increase muscle mass by elevating protein synthesis and/or reducing protein degradation. The increase in protein synthesis allows the animal to produce more lean muscle tissue. Optaflexx (Elanco Animal Health, Greenfield, IN) is a popular β-AA that works as a repartitioning agent to redirect nutrients toward muscle deposition and away from adipose tissue production. The two technologies utilize ...

The Real Trouble With Risk Assessment, Valery E. Forbes 2015 University of Nebraska-Lincoln

The Real Trouble With Risk Assessment, Valery E. Forbes

Valery Forbes Publications

In their article, “Pesticide regulation amid the influence of industry,” Boone and colleagues (2014) contend that a major weakness of the US Environmental Protection Agency’s pesticide risk assessment is the use of industry-supplied data, which has inherent conflicts of interest. Therefore, studies performed by industry scientists or funded by indus!try sources are considered by the authors to be inherently biased and therefore not to be trusted, the implication being that publications by academic scientists or those funded by nonindustry sources are bias free and, therefore, by definition, suitable for use in risk assessment. However, the funding source is ...

Benton, Alice Johnstone, David Eccles, Brennan Harmon, Mark T. Hayes, Rod A. Lea, Lyn Griffiths, Eric P. Hoffman, Richard S. Stubbs, Donia Macartney-Coxson

Integrative Systems Biology Faculty Publications

Background

Environmental factors can influence obesity by epigenetic mechanisms. Adipose tissue plays a key role in obesity-related metabolic dysfunction, and gastric bypass provides a model to investigate obesity and weight loss in humans.

Results

Here, we investigate DNA methylation in adipose tissue from obese women before and after gastric bypass and significant weight loss. In total, 485,577 CpG sites were profiled in matched, before and after weight loss, subcutaneous and omental adipose tissue. A paired analysis revealed significant differential methylation in omental and subcutaneous adipose tissue. A greater proportion of CpGs are hypermethylated before weight loss and increased methylation ...

Glycogen is the major mammalian glucose storage cache and is critical for energy homeostasis. Glycogen synthesis in neurons must be tightly controlled due to neuronal sensitivity to perturbations in glycogen metabolism. Lafora disease (LD) is a fatal, congenital, neurodegenerative epilepsy. Mutations in the gene encoding the glycogen phosphatase laforin result in hyperphosphorylated glycogen that forms water-insoluble inclusions called Lafora bodies (LBs). LBs induce neuronal apoptosis and are the causative agent of LD. The mechanism of glycogen dephosphorylation by laforin and dysfunction in LD is unknown. We report the crystal structure of laforin bound to phosphoglucan product, revealing its unique integrated ...

The Effects Of Environmental Prompts On Stair Usage, Lori Andersen, Tim Bungum, Sheniz Moonie Phd

Nevada Journal of Public Health

Experts have advocated exercise with little success, and have turned to encouraging physical activity by incorporating it into daily activities such as taking the stairs over elevators. Much literature exists suggesting that environmental prompts can encourage the use of stairs and literature has established that some messages may be more effective than others. This study aimed to assess the effects of selected signage prompts on stair usage. Methods: Stair and elevator use were monitored in three, two-story buildings. One building served as a control, while a fitness message was placed in another building, and the final building received a weight ...

Inclusion of perennial vegetation filter strips (PFSs) in the toeslope of annual cropland watersheds can decrease NO3–N losses to ground and surface waters. Although PFSs are similar to riparian buffers, the processes responsible for NO3–N removal from PFSs are not well understood. Our objectives were to (i) determine the importance of denitrification as a sink for NO3–N loss from PFSs and (ii) evaluate how PFSs alter the biophysical processes that affect the relative importance of N2O and N2 emissions. To address our objectives, we used a coupled field laboratory approach with ...
