School of Dentistry Faculty Research and Publications

In this research, the three dimensional porous scaffolds made of a polycaprolactone (PCL) microsphere/TiO₂ nanotube (TNT) composite was fabricated and evaluated for potential bone substitute applications. We used a microsphere sintering method to produce three dimensional PCL microsphere/TNT composite scaffolds. The mechanical properties of composite scaffolds were regulated by varying parameters, such as sintering time, microsphere diameter range size and PCL/TNT ratio. The obtained results ascertained that the PCL/TNT (0.5 wt%) scaffold sintered at 60 °C for 90 min had the most optimal mechanical properties and an appropriate pore structure for bone tissue engineering applications. The average pore size …

This work formulates capacity planning over a time horizon as a …

Protein Structure Classification And Loop Modeling Using Multiple Ramachandran Distributions, Seyed Morteza Najibi, Mehdi Maadooliat, Lan Zhou, Jianhua Z. Huang, Xin Gao

Mathematics, Statistics and Computer Science Faculty Research and Publications

Recently, the study of protein structures using angular representations has attracted much attention among structural biologists. The main challenge is how to efficiently model the continuous conformational space of the protein structures based on the differences and similarities between different Ramachandran plots. Despite the presence of statistical methods for modeling angular data of proteins, there is still a substantial need for more sophisticated and faster statistical tools to model the large-scale circular datasets. To address this need, we have developed a nonparametric method for collective estimation of multiple bivariate density functions for a collection of populations of protein backbone angles. …

Identification Of Multiple Functional Receptors For Tyramine On An Insect Secretory Epithelium, Haiying Zhang, Edward M. Blumenthal

Biological Sciences Faculty Research and Publications

The biogenic amine tyramine (TA) regulates many aspects of invertebrate physiology and development. Although three TA receptor subtypes have been identified (TAR1-3), specific receptors have not been linked to physiological responses in native tissue. In the Malpighian (renal) tubule of Drosophila melanogaster, TA activates a transepithelial chloride conductance, resulting in diuresis and depolarization of the transepithelial potential. In the current work, mutation or RNAi-mediated knockdown in the stellate cells of the tubule of TAR2 (tyrR, CG7431) resulted in a dramatic reduction, but not elimination, of the TA-mediated depolarization. Mutation or knockdown of TAR3 (tyrRII, …

Synthesis Of N-Acetyl-ᴅ-Quinovosamine In Rhizobium Etli Ce3 Is Completed After Its 4-Keto-Precursor Is Linked To A Carrier Lipid, Tiezheng Li, K. Dale Noel

Biological Sciences Faculty Research and Publications

Bacterial O-antigens are synthesized on lipid carriers before being transferred to lipopolysaccharide core structures. Rhizobium etli CE3 lipopolysaccharide is a model for understanding O-antigen biological function. CE3 O-antigen structure and genetics are known. However, proposed enzymology for CE3 O-antigen synthesis has been examined very little in vitro, and even the sugar added to begin the synthesis is uncertain. A model based on mutagenesis studies predicts that 2-acetamido-2,6-dideoxy-d-glucose (QuiNAc) is the first O-antigen sugar and that genes wreV, wreQ and wreU direct QuiNAc synthesis and O-antigen initiation. Previously, synthesis of UDP-QuiNAc was shown to occur in vitro with a WreV …

H+- And Na+- Elicited Rapid Changes Of The Microtubule Cytoskeleton In The Biflagellated Green Alga Chlamydomonas, Yi Liu, Mike Visetsouk, Michelle Mynlieff, Hongmin Qin, Karl F. Lechtreck, Pinfen Yang

Biological Sciences Faculty Research and Publications

Although microtubules are known for dynamic instability, the dynamicity is considered to be tightly controlled to support a variety of cellular processes. Yet diverse evidence suggests that this is not applicable to Chlamydomonas, a biflagellate fresh water green alga, but intense autofluorescence from photosynthesis pigments has hindered the investigation. By expressing a bright fluorescent reporter protein at the endogenous level, we demonstrate in real time discreet sweeping changes in algal microtubules elicited by rises of intracellular H⁺ and Na⁺. These results from this model organism with characteristics of animal and plant cells provide novel explanations regarding …

Biocompatible Copper Oxide Nanoparticle Composites From Cellulose And Chitosan: Facile Synthesis, Unique Structure, And Antimicrobial Activity, Chieu D. Tran, James Makuvaza, Erik Munson, Brian Bennett

Chemistry Faculty Research and Publications

Copper in various forms has been known to have bactericidal activity. Challenges to its application include preventing mobilization of the copper, to both extend activity and avoid toxicity, and bioincompatibility of many candidate substrates for copper immobilization. Using a simple ionic liquid, butylmethylimmidazolium chloride as the solvent, we developed a facile and green method to synthesize biocompatible composites containing copper oxide nanoparticles (CuONPs) from cellulose (CEL) and chitosan (CS) or CEL and keratin (KER). Spectroscopy and imaging results indicate that CEL, CS, and KER remained chemically intact and were homogeneously distributed in the composites with CuONPs with size of 22 …

Church, State & The Trump Administration, Public Rights/Private Conscience Project

Center for Gender & Sexuality Law

President Donald Trump has repeatedly pledged to be a staunch defender of religious liberties. Nevertheless, his campaign promises, as well as statements made by him and his cabinet appointees, suggest that Trump holds a limited and deeply flawed understanding of religious freedom, among other constitutional rights and guarantees. While members of the new administration will act quickly and aggressively to advance certain conservative Christian religious tenets by limiting the rights of LGBTQ communities and curtailing access to reproductive health care, the President has promised to significantly restrain the rights of religious minorities by imposing a Muslim immigration ban, increase profiling …

Sports Corruption: The History And Challenges Of Anti-Doping Regimes In The U.S. And Abroad, Shlomo Fischer

Center for the Advancement of Public Integrity (Inactive)

The International Olympic Committee first began drug-testing in response to the death of Knud Enemark Jensen, a Danish cyclist who collapsed of heatstroke during the 1960 Olympics in Rome and whose autopsy suggested that amphetamines played a role in his death. A wide range of performance enhancing substances was formally banned, and doping tests were administered to preserve the integrity of competition and to protect the health of athletes. The IOC’s initial regime was neither systematic nor robust, lacking both methodologically and technologically. However, the gap between doping and monitoring gradually began to close as testing became more accurate and …

Upstream Sources Inhibit Benthic Phosphorus Fluxes In The Lower Great Miami River, Southwest Ohio, Kortney Mullen

Browse all Theses and Dissertations

Human activities have increased nutrient loadings to aquatic ecosystems during the past century. During low river flow in late summer and early fall, excessive concentrations of phosphorus (P) are present in the Lower Great Miami River (LGMR) and contribute to its eutrophication. Although wastewater treatment plants are suspected of being major point sources of P to the LGMR during low river flow, riverbed sediment has not been examined as an additional potential source of P. Benthic P fluxes were measured at 11 representative locations along the LGMR during late summer and early fall of 2015. Sediment and overlying water sampled …

Infection Prevalence In A Novel Ixodes Scapularis Population In Northern Wisconsin, Mary Lynn Westwood

Browse all Theses and Dissertations

Ixodes scapularis (i.e. the blacklegged or deer tick) is an important vector of emerging human pathogens. Over the past few decades, the incidence of blacklegged tick-associated zoonotic diseases have increased in accordance with an expansion of the blacklegged tick geographic range. Data concerning the infection prevalence of blacklegged ticks in this region is highly variable and fragmentary. Using a novel population of these ticks, constituting part of the invasion front in Vilas County, Wisconsin, I examined infection prevalence and vector aspects of their ecology. During the summer of 2016, I collected 461 blacklegged ticks and screened them using a standard …
