Development Of Novel Pectinase And Xylanase Juice Clarification Enzymes Via A Combined Biorefinery And Immobilization Approach, Shady Hassan

Doctoral

Hydrolytic enzymes, such as pectinase and xylanase, maybe harnessed for numerous industrial applications in food industry. Therefore, economic factors such as achievement of optimum yieldsandoverall production costs, in addition to biocatalyst instability,are the main obstacles tothe industrial production and exploitation of a enzymes. For example, microbially-derived enzymes are typically produced in fermenters using expensive growth media, which may account for 30 to 40% of the production cost, and such expense may be compounded further by downstream processing operations.To counter such disadvantages, the major trend in industrial utilization of enzymes in cost-sensitive processes has been to immobilize such biocatalysts on a …

Effects Of Temporal Variation On Ambient Light In Northwest Arkansas, Ashlyn Anderson

Biological Sciences Undergraduate Honors Theses

An animal’s life success is determined solely by its fitness, which makes choosing a mate one of its most important life decisions. Natural selection plays a big part in an animal’s phenotype, but so does sexual selection. Even though females are usually thought to be the choosier sex, in many species or seasons males are also choosy. Male mate preference is an understudied topic compared to female mate preference and therefore, even less is known about the outcomes of a male’s prior mating experience’s influence on future mating experiences. Therefore, I dove deeper into this topic with the highly studied …

The Effects Of Multiple Stressors On Stream Communities: The Convergence Of Drought, Nutrient Pollution, And Invasive Species, Robert Joseph Fournier Iii

Graduate Theses and Dissertations

Freshwater systems experience multi-faceted degradation from a variety of ecological and environmental stressors. Three common stressors in these systems, drought, nutrient pollution, and invasive species, have wide-ranging effects on stream population- community- and ecosystem dynamics. We have a broad understanding of how each of these stressors works to influence stream systems independently. However, we still know relatively little about if, and how, these stressors might interact when they co-occur. Though drought is a natural part of many stream systems, all three of these stressors can be exacerbated or facilitated by anthropogenic actions. Accordingly, as human population and resource use continue …

Safety, Crisis, And Criminal Law, Jenny E. Carroll

Faculty Scholarship

Concepts of safety and prevention of danger pervade the criminal law canon. Arizona is no exception. The state’s criminal systems pivot around central and entwined goals of protecting public safety and preventing danger. The state constitution permits pretrial detention both for the most serious offenses and when no other condition of release will adequately protect the community from the danger the accused’s freedom might pose. The rules of criminal procedure and the criminal code designate some offenses and actors “dangerous” and urge judges to weigh not only the accused’s risk of flight, but also his future dangerousness in making decisions …

The Role Of Angiogenesis-Inducing Micrornas In Vascular Tissue Engineering, May-Hui Ding, Eloy G. Lozoya, Rene N. Rico, Sue Anne Chew

Health & Biomedical Sciences Faculty Publications

Angiogenesis is an important process in tissue repair and regeneration as blood vessels are integral to supply nutrients to a functioning tissue. In this review, the application of microRNAs (miRNAs) or anti-miRNAs that can induce angiogenesis to aid in blood vessel formation for vascular tissue engineering in ischemic diseases such as peripheral arterial disease and stroke, cardiac diseases, and skin and bone tissue engineering is discussed. Endothelial cells (ECs) form the endothelium of the blood vessel and are recognized as the primary cell type that drives angiogenesis and studied in the applications that were reviewed. Besides ECs, mesenchymal stem cells …

Knifefish’S Suction Makes Water Boil, Victor M. Ortega-Jimenez, Christopher P.J. Sanford

Faculty Articles

We discovered that knifefish (Apteronotus albifrons) during suction feeding can produce millimeter-sized cavitation bubbles and flow accelerations up to ~ 450 times the acceleration of gravity. Knifefish may use this powerful suction-induced cavitation to cause physical damage on prey hiding in narrow refuges, therefore facilitating capture.

An In Silico Approach To Analyze Hcv Genotype-Specific Binding-Site Variation And Its Effect On Drug-Protein Interaction, Ramsha Khalid, Muhammad Faraz Anwar, Muhammad Aanish Raees, Sadaf Naeem, Syed Hani Abidi, Syed Ali

Department of Biological & Biomedical Sciences

Genotype variation in viruses can affect the response of antiviral treatment. Several studies have established approaches to determine genotype-specific variations; however, analyses to determine the effect of these variations on drug-protein interactions remain unraveled. We present an in-silico approach to explore genotype-specific variations and their effect on drug-protein interaction. We have used HCV NS3 helicase and fluoroquinolones as a model for drug-protein interaction and have investigated the effect of amino acid variations in HCV NS3 of genotype 1a, 1b, 2b and 3a on NS3-fluoroquinolone interaction. We retrieved 687, 667, 101 and 248 nucleotide sequences of HCV NS3 genotypes 1a, 1b, …

Metabolomics Of Acid Whey Derived From Greek Yogurt, Muriel Mercedes Allen

Theses and Dissertations

Acid whey, a byproduct of Greek yogurt production, has little commercial value due to its low protein content and is also environmentally harmful when disposed of as waste. However, as a product of microbial fermentation, acid whey could be a rich source of beneficial metabolites associated with fermented foods. This study increases understanding of acid whey composition by providing a complete metabolomic profile of acid whey. Commercial and lab-made Greek yogurts, prepared with three different bacterial culture combinations, were evaluated. Samples of unfermented yogurt mix and cultured whey from each batch were analyzed. Ultra-high-performance liquid chromatography/tandem mass spectrometry metabolomics were …
