Acidulant Effect On Greening, Reducing Capacity, And Tryptophan Fluorescence Of Sunflower Butter Cookie Dough During Refrigerated Storage, Joele Tsopkeng Atonfack, Zeynep Akyol Ataman, Lilian M. Were

Food Science Faculty Articles and Research

BACKGROUND: Sunflower seed derived butter can be a source of protein and phenolic antioxidants in refrigerated dough. Chlorogenic quinone-amino acid induced greening can however occur at alkaline pH, which could result in less bioavailable conjugated phenol-amino acids. Acidulants were tested as potential anti-greening ingredients in refrigerated chemically leavened cookie dough. Effect of refrigerated storage time, leavening agents and acidulants on tryptophan fluorescence (»ex=280nm, »em=300-500), color (hunter LAB), reducing capacity (DPPH and Folin-Ciocalteu reagent reducing capacity/FCRC), and hydroxycinnamic acids were measured.

RESULTS: The pH range of acidified doughs was 4.83–6.98 compared to 7.65- 9.18 in nonacidified leavened doughs after 24 days. …

Genome-Wide Screening Identifies Genes And Biological Processes Implicated In Chemoresistance And Oncogene-Induced Apoptosis, Tengyu Ko

LSU Doctoral Dissertations

Anti-proliferative responses such as senescence and apoptosis are often used by normal cells to combat oncogenic insults and to prevent tumorigenesis. However, oncogenic mutations are frequently found in cancers, suggesting that additional mutations may occur to facilitate the bypass of these anti-proliferative responses. It is believed that some of these additional mutations may also contribute to the chemoresistance of cancers. This dissertation focused on identifying novel genes and biological processes implicated in chemoresistance and tumorigenesis.

Cisplatin-based chemotherapeutic regimens are frequently used for treatments of solid tumors. However, tumor cells may have inherent or acquired resistance to cisplatin, and the underlying …

Whole-Tree Nonstructural Carbohydrate Storage And Seasonal Dynamics In Five Temperate Species, Morgan E. Furze, Brett A. Huggett, Donald M. Aubrecht, Claire D. Stolz, Mariah S. Carbone, Andrew D. Richardson

All Faculty Scholarship

Despite the importance of nonstructural carbohydrates (NSC) for growth and survival in woody plants, we know little about whole-tree NSC storage. The conventional theory suggests that NSC reserves will increase over the growing season and decrease over the dormant season. Here, we compare storage in five temperate tree species to determine the size and seasonal fluctuation of whole-tree total NSC pools as well as the contribution of individual organs. NSC concentrations in the branches, stemwood, and roots of 24 trees were measured across 12 months. We then scaled up concentrations to the whole-tree and ecosystem levels using allometric equations and …

Local Mapping Profile Of Mitochondrial Dna (Mtdna)-Loop In Forensic Identification, Ahmad Yudianto, Nola Margaret

Folia Medica Indonesiana

To prove that mitochondrial DNA damage is not total or partial, as has been found in the preliminary study, studies need to be done to determine the opportunity of successful use of the mitochondrial DNA mini-primer set in an amplicon product below 250 bp. This is important because it can overcome quality problems in degraded DNA, which will complicate the process of DNA forensic identification. This was an observational analytic study with cross sectional design. The study material was DNA from blood and sweat stains taken from abandoned bodies. Samples consisted of 24 pieces of blood and sweat spots. The …

Folia Medica Indonesiana

Tuberculosis in children is often a systemic complication because of their imperfect cellular immune system. ESAT-6, CFP-10, and MPT-64 are small molecular dominant antigens secreted by Mtb into the blood and filtered by the kidneys into urine. The high proportion of children with TB cases according to the Ministry of Health of the Republic of Indonesia in 2013 was 7.9%-12%. Diagnis is difficult to establish with sputum and blood samples. Therefore, it is necessary to support the diagnosis using urine samples with ICT rapid test. The purpose of this study was to determine the examination of Mtb ESAT-6, CFP-10, and …

Through Army-Colored Glasses: A Layered Account Of One Veteran’S Experiences In Higher Education, Phillip A. Olt

The Qualitative Report

There is a lack of research on military veterans in higher education that captures the issues from an insider’s perspective. To that end, I sought to reflect upon my own experiences with higher education as military veteran—from a budding recruit all the way through to now being an administrator and faculty member. I utilized a layered-account autoethnographic approach (Ronai, 1995) to interrogate my multiple perspectives that developed over time on veterans’ issues in higher education. I found that the GI Bill—the modern iteration of the Serviceman’s Readjustment Act of 1944—was a powerful motivator both in starting my military career and …

Dissolution: The Achilles' Heel Of The Triton Shell In An Acidifying Ocean, Ben P. Harvey, Sylvain Agostini, Shigeki Wada, Kazuo Inaba, Jason M. Hall-Spencer

School of Biological and Marine Sciences

© 2018 Harvey, Agostini, Wada, Inaba and Hall-Spencer. Ocean acidification is expected to negatively impact many calcifying marine organisms by impairing their ability to build their protective shells and skeletons, and by causing dissolution and erosion. Here we investigated the large predatory "triton shell" gastropod Charonia lampas in acidified conditions near CO2 seeps off Shikine-jima (Japan) and compared them with individuals from an adjacent bay with seawater pH at present-day levels (outside the influence of the CO2 seep). By using computed tomography we show that acidification negatively impacts their thickness, density, and shell structure, causing visible deterioration to the shell …

You Get What You Deserve: The Struggle For Worthiness Of International Students And Workers, Hoa Bui

Journal of Critical Scholarship on Higher Education and Student Affairs

To attack the current immigration policies, Trump borrowed largely from the assumption that the current system is not a meritocracy, bringing in unworthy immigrants. Reflecting on the heavy influence from her mother, her journey, and experiences that led to her present life as a “legal alien” studying and working predominantly in the American higher education system, the author questioned the assumptions behind the idea of worthiness, deservingness, and responsibility. Anchored from post-colonialism theories, the authored outlined the challenges and potentials for those with similar immigration status and educational privilege.

When Strange Bedfellows Go All In: A Template For Implementing Non-Lethal Strategies Aimed At Reducing Carnivore Predation Of Livestock, Julie K. Young, John Steuber, Alexandra Few, Adam Baca, Zack Strong

Wildland Resources Faculty Publications

In the Rocky Mountains of the USA, abundances and distributions of grizzly bear Ursus arctos and gray wolf Canis lupus have increased (Bangs et al., 2001; Nicholson & Hendricks, 2018). This has led to increased predation of livestock in areas where livestock producers have not needed to implement conflict prevention methods in recent history. Lethal removal of carnivores that kill livestock remains a common source of carnivore mortalities (Woodroffe, 2001; Broekhuis, Cushman & Elliot, 2017). In the USA, the U.S. Department of Agriculture’s Wildlife Services (USDA-WS) is often asked by the U.S. Fish and Wildlife Service or a State’s wildlife …

Section of Neurosurgery

Glioblastoma, also known as glioblastoma multiforme (GBM), is the most common primary brain tumor. Extensive research has been carried out to discover the factors associated with the course and progression of GBM. CD133 is a glycoprotein antigen found in normal and malignant tissues. CD133 has been recognized as a marker for the growth of cancer cells. The association between this tissue marker and GBM is being investigated. The aim of this review was to evaluate the role of CD133 as a tumor marker for the prognosis of GBM.

An Expanded Modern Coexistence Theory For Empirical Applications, Stephen P. Ellner, Robin E. Snyder, Peter B. Adler, Giles J. Hooker

Ecology Center Publications

Understanding long‐term coexistence of numerous competing species is a longstanding challenge in ecology. Progress requires determining which processes and species differences are most important for coexistence when multiple processes operate and species differ in many ways. Modern coexistence theory (MCT), formalized by Chesson, holds out the promise of doing that, but empirical applications remain scarce. We argue that MCT's mathematical complexity and subtlety have obscured the simplicity and power of its underlying ideas and hindered applications. We present a general computational approach that extends our previous solution for the storage effect to all of standard MCT's spatial and temporal coexistence …

Investigating Pre-Service Secondary Mathematics Teachers’ Reasoning When Learning Trigonometry Using The Line Segment Approach, Lawrence Ssebaggala

Theses and Dissertations

Review of the history of trigonometry content and pedagogy indicates the necessity and importance of trigonometry in the school curriculum (e.g., van Brummelen, 2009; van Sickel, 2011). For example, understanding trigonometric functions is a requirement for understanding some other areas of science, such as Newtonian physics, architecture, surveying, and several branches of engineering. Research indicates that teachers have a narrow and inadequate understanding of trigonometry, researchers (e.g., Hertel, 2013; van Sickel, 2011; Weber, 2005) posited that learning trigonometry in a way that fosters and advances quantitative reasoning can help alleviate difficulties faced in the teaching of trigonometry. Examining participants’ reasoning …

Orderliness Of Visual Stimulus Motion Mediates Sensorimotor Coordination, Joshua L. Haworth, Nicholas Stergiou

Journal Articles

We explored the coupling of gaze and postural sway to the motion of a visual stimulus, to further understand sensorimotor coordination. Visual stimuli consisted of a horizontally oscillating red dot, moving with periodic (sine), chaotic, or aperiodic (brown noise) temporal structure. Cross Recurrence Quantification Analysis (cRQA) was used to investigate the coupling between each measured signal with the time series of the visual stimulus position. The cRQA parameter of percent determinism indicated similar strength of coupling of gaze with either periodic or chaotic motion structures, yet weaker coupling to aperiodic stimulus motion. The cRQA parameter of Maxline indicated a particular …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Background: Metformin, an oral anti-hyperglycemic drug which inhibits mitochondrial complex I and oxidative phosphorylation has been reported to correlate with improved outcomes in head and neck squamous cell carcinoma (HNSCC) and other cancers. This effect is postulated to occur through disruption of tumor-driven metabolic and immune dysregulation in the tumor microenvironment (TME). We report new findings on the impact of metformin on the tumor and immune elements of the TME from a clinical trial of metformin in HNSCC. Methods: Human papilloma virus-(HPV-) tobacco+ mucosal HNSCC samples (n = 12) were compared to HPV+ oropharyngeal squamous cell carcinoma (OPSCC) samples (n …
