Decolorization Of Hair Dye By Lignocellulosic Waste Materials From Contaminated Waters, Habib Zahir, Michelle Naidoo, Rada-Mayya Kostadinova, Karla A. Ortiz, Rosario Sun-Kuo, Abel E. Navarro

Publications and Research

Basic yellow 57 (BY57) was chosen as a model hair dye due to its prevalence in cosmetics wastewaters. This study proposes the use of lignocellulosic materials like spent tea leaves of peppermint (PM), chai tea (CT), and chamomile (CM) as raw adsorbents for the removal of BY57 from contaminated solutions. Batch adsorption experiments were carried out at room temperature to achieve the maximum adsorption capacity. Results indicate that the highest removal is achieved at pH 6–8, with a minimum adsorbent mass of 75 mg and in the absence of salinity, crowding agents and heavy metals. Adsorption equilibria were modeled according …

The Role Of Vitamin E In Human Health And Some Diseases, Saliha Rizvi, Syed T. Raza, Faizal Ahmad, Absar, Shania Abbas, Farzana Mahdi

Sultan Qaboos University Medical Journal

Vitamin E is the major lipid-soluble component in the cell antioxidant defence system and is exclusively obtained from the diet. It has numerous important roles within the body because of its antioxidant activity. Oxidation has been linked to numerous possible conditions and diseases, including cancer, ageing, arthritis and cataracts; vitamin E has been shown to be effective against these. Platelet hyperaggregation, which can lead to atherosclerosis, may also be prevented by vitamin E; additionally, it also helps to reduce the production of prostaglandins such as thromboxane, which cause platelet clumping. The current literature review discusses the functions and roles of …

Direct Evidence For Calcineurin Binding To The Exon-7 Loop Of The Sodium-Bicarbonate Transporter Nbcn1, Harindarpal S. Gill, Eric D. Roush, Lauren Dutcher, Samir Patel

Medicine Faculty Publications

The NaHCO3 cotransporter NBCn1 plays a role in neutralizing intracellular acid loads at the basolateral membrane in cells of the medullary thick ascending limb (mTAL). Calcineurin inhibitors (Cn-Is) are known to both downregulate NBCn1 expression in the distal nephron and cause renal tubular acidosis (RTA), a risk factor for nephrocalcinosis and nephrolithiasis. In this report, we provide a new perspective on concurrent studies of NBCn1 in various tissues by using cell-free binding assays to investigate the interaction of NBCn1 with the calcineurin (Cn) isoform PPP3CA. Surface plasmon resonance (SPR) analyses show that the protein domain Exon 7 (translated from cassette …

Chemicals Facilitating Reprogramming: Targeting The Sam Binding Site To Identify Novel Methyltransferase Inhibitors, Jeong Do Kim, Jong S. Rim, Robert B. Crochet, Yong Hwan Lee, Jaroslaw Staszkiewicz, Ru Gao, Kenneth J. Eilertsen

Faculty Publications

© 2014 John Wiley & Sons, Ltd. Reprogramming of somatic cells to a pluripotent state has been achieved by viral-mediated transduction of defined transcription factors. In order to achieve the goal of clinical application, it is necessary to overcome a variety of limitations, including poor reprogramming efficiencies and viral integration. One strategy is to identify small-molecule inhibitors that can improve reprogramming efficiency or replace defined transcription factors. Several reports have demonstrated that modulation of chromatin-modifying enzymes can significantly improve reprogramming efficiency. Key enzymes include DNA and histone methyltransferases, which utilize the cofactor S-adenosyl methionine (SAM) to transfer a methyl group. …

Dual-Channel Red/Blue Fluorescence Dosimetry With Broadband Reflectance Spectroscopic Correction Measures Protoporphyrin Ix Production During Photodynamic Therapy Of Actinic Keratosis, Stephen Chad Kanick, Scott C. Davis, Yan Zhao, Tayyaba Hasan, Edward V. Maytin, Brian W. Pogue, M Shane Chapman

Dartmouth Scholarship

Dosimetry for aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) photodynamic therapy of actinic keratosis was examined with an optimized fluorescence dosimeter to measure PpIX during treatment. While insufficient PpIX generation may be an indicator of incomplete response, there exists no standardized method to quantitate PpIX production at depths in the skin during clinical treatments. In this study, a spectrometer-based point probe dosimeter system was used to sample PpIX fluorescence from superficial (blue wavelength excitation) and deeper (red wavelength excitation) tissue layers. Broadband white light spectroscopy (WLS) was used to monitor aspects of vascular physiology and inform a correction of fluorescence for …

Perceived Impacts Of A Public Health Training Center Field Placement Program Among Trainees: Findings From A Small Group Externship Experience, Patrik Johansson, Brandon Grimm, Tarik Abdel-Monem, Stacey J. Hoffman, Mark Dekraai, Analisa Mcmillan

University of Nebraska Public Policy Center: Publications

There is heightened interest in identifying the impact of the federally funded Public Health Training Center (PHTC) program. Although evaluation studies have been conducted of public health training in general, evaluations of PHTC programs are rare. Field placement components are congressionally mandated requirements of PHTCs. Field placements are typically intensive, supervised externships for students to gain public health experience with local health departments or non-profit organizations. We have found no published evaluations of PHTC field placement components. This may be because of their small size and unique nature. We designed and evaluated a 200-h field placement program at an established …

Oswald Physical And Engineering Sciences First Place: An Improved In Vitro Model For The Study Of Endothelial Cells Using Micropatterned Surfaces, Lindsay Gray

Kaleidoscope

Sickle cell anemia, malaria, and cancer are a few of the deadly diseases that utilize blood vessels as a means of migration throughout the body. Adhesion of harmful cells to the endothelial lining of the circulatory system is an integral step in the metastasis of blood borne diseases. As a result of shear stress produced by blood flow through veins and arteries, the endothelium undergoes a distinct morphological change resulting in a more elongated and unidirectional morphology. It has recently been suggested that such changes in cell morphology can affect surface expression profiles, which in turn affects cell-cell binding and …

Oswald Physical And Engineering Sciences Second Place: Multiple Macromer Hydrogels For Multiphase Drug Release, David Spencer

Kaleidoscope

Biodegradable hydrogels are of interest for drug delivery applications due to their resemblance to biological tissue and their ability to absorb large amounts of biological fluids. Here, hydrogels were synthesized from multiple macromers to demonstrate step-wise degradation and multiphase drug release profiles. Control over the degradation and release profiles of multiple macromer hydrogels has potential applications in implantable, extended release drug delivery devices in which removal would not be needed after administration. Herein, macromers were synthesized from diethylene glycol diacrylate (A), poly(ethylene glycol) diacrylate (n=400) (H), and isobutylamine (6) in 1.2:1 molar ratios of total diacrylate to amine with diacrylate …

Oswald Biological Sciences First Place: Development Of Three-Dimensional Lung Multicellular Spheroids In Air And Liquid Interface Culture For The Evaluation Of Anti-Cancer Therapeutics, Alexandra Tsoras

Kaleidoscope

The implementation of in vitro results to in vivo applications has limitations due to conventional two-dimensional (2D) in vitro conditions lacking the ability to create a physiologically representative model. This study investigated a three-dimensional (3D) cell culture technique to model lung tumors in vitro. A 3D lung cancer model was created by applying collagen (a semi-non-adhesive material) to a transwell, which allowed for nutrient transfer through the collagen. Two lung cancer cells lines (H358, a bronchioalveolar carcinoma and A549, a lung adenocarcinoma) were seeded on top of the collagen. The non-adhesive collagen allowed the cells to preferentially attach to one …

Oswald Biological Sciences Second Place: Rna Degradation Is Elevated With Age-, But Not Disuse-Associated Skeletal Muscle Atrophy, Aman Shah

Kaleidoscope

Aging and inactivity are both associated with decreased muscle size and protein content. The possible role of RNA degradation in the loss of protein has not yet been investigated. Therefore, we hypothesized that RNA degradation was elevated with muscle atrophy in aging and disuse. Brown Norway/Fisher344 male rats at 6 and 32 months were hindlimb suspended (HS) for 14 days to induce muscle atrophy or remained weight bearing (WB). Cytosolic extracts from gastrocnemius muscles were prepared for Western analysis of DCP-2 protein (marker of p-bodies) and RNA degradation assay. In vitro total RNA decay assay was performed using 30ug of …

Oswald Biological Sciences Honorable Mention: A Tragedy Exposed? Clear Growth Medium Reveals Roots Competing, Christopher Karounos

Kaleidoscope

A Tragedy of the Commons (ToC) models many systems of human exploitation of natural resources. In a plant-systems application of ToC, multiple plants compete over shared nutrients and space. Tragically these resources become exhausted due to their open-access to multiple plants. Our study focuses on determining whether two competing plants pay a reproductive cost due to ToC. We predict that plants create a ToC and subsequently pay a reproductive cost. We quantify a ToC by measuring a plant’s reproductive mass as well as its total root mass. Typically, ToC lowers reproductive mass and raises total root mass. Our study uses …

The Unintended Federalism Consequences Of The Affordable Care Act’S Insurance Market Reforms, Joshua Phares Ackerman

Pace Law Review

This Article, which is the first to examine the relationship between the ACA’s insurance market reforms and state regulation of insurance, argues that states’ decisions to forego creating their own exchanges may mark the beginning of an important shift of regulatory authority from the states to the federal government. It begins by sketching the historical antecedents of the current allocation of state and federal authority over insurance regulation. The aim of this discussion is to highlight the unique role states play in the regulation of insurance as opposed to other financial products. Part III explains the pre-ACA structure of health …

Biomedical and Pharmaceutical Sciences Faculty Publications

Adiponectin is a protein hormone that modulates glucose metabolism and fatty acid oxidation. Weexplored the clinical implication of serum adiponectin in hepatogenic diabetes. Serum adiponectin levels were determined using enzyme–linked immunochemistry assay in 78 individuals including 19 hepatogenic diabetes, 20 type 2 diabetes (T2D), 20 chronic liver disease and 19 healthy controls. Cases and controls were matched by gender and body mass index (BMI). There is no difference in serum adiponectin levels among hepatogenic diabetic, T2D and healthy control groups. The levels of adiponectin are highest in chronic liver disease and lowest in T2D. Insulin levels are highest in hepatic …

Human Brain Networks: Spiking Neuron Models, Multistability, Synchronization, Thermodynamics, Maximum Entropy Production, And Anesthetic Cascade Mechanisms, Wassim H. Haddad, Qing Hui, James M. Bailey

Department of Electrical and Computer Engineering: Faculty Publications

Advances in neuroscience have been closely linked to mathematical modeling beginning with the integrate-and-fire model of Lapicque and proceeding through the modeling of the action potential by Hodgkin and Huxley to the current era. The fundamental building block of the central nervous system, the neuron, may be thought of as a dynamic element that is “excitable”, and can generate a pulse or spike whenever the electrochemical potential across the cell membrane of the neuron exceeds a threshold. A key application of nonlinear dynamical systems theory to the neurosciences is to study phenomena of the central nervous system that exhibit nearly …

Evaluation Of A New Method Of Fossil Retrodeformation By Algorithmic Symmetrization: Crania Of Papionins (Primates, Cercopithecidae) As A Test Case, Melissa Tallman, Nina Amenta, Eric Delson, Stephen R. Frost, Deboshmita Ghosh, Zachary S. Klukkert, Andrea Morrow, Gary J. Sawyer

Publications and Research

Diagenetic distortion can be a major obstacle to collecting quantitative shape data on paleontological specimens, especially for three-dimensional geometric morphometric analysis. Here we utilize the recently -published algorithmic symmetrization method of fossil reconstruction and compare it to the more traditional reflection & averaging approach. In order to have an objective test of this method, five casts of a female cranium of Papio hamadryas kindae were manually deformed while the plaster hardened. These were subsequently “retrodeformed” using both algorithmic symmetrization and reflection & averaging and then compared to the original, undeformed specimen. We found that in all cases, algorithmic retrodeformation improved …

Investigation Of Spatial Isotope Ratios In Soil And The Effects Of Fertilizer On Plant Isotope Ratios, Jamie Kim, H. Thomas Goodwin Ph.D.

Posters, Presentations, and Papers

A previous Honors study analyzed diet of thirteen-lined ground squirrels at the Andrews University Airpark by studying δ13C and δ15N isotope values of their fecal pellets (Chacko, 2013). Fecal samples collected within 25m of a cornfield had elevated isotope values.

High δ13C values indicate greater consumption of C4 plants, such as corn (Ehleringer et al., 1986); high δ15N values indicate increased consumption of animal matter (DeNiro and Epstein, 1981 ). However, the spatial pattern may be due to variation in the soil, reflecting long-term patterns in the vegetation.

Soil samples were taken throughout the airpark and analyzed for δ13C and …
