Gallium-Containing Mesoporous Bioactive Glass With Potent Hemostatic Activity And Antibacterial Efficacy, Sara Pourshahrestani, Ehsan Zeimaran, Nahrizul Adib Kadri, Nicola Gargiulo, Shani Samuel, Sangeetha Vasudevaraj Naveen, Tunku Kamarul, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

Haemorrhage remains the leading cause of potentially survivable death in both military and civilian populations. Although a large variety of hemostatic agents have been developed, many of them have an inadequate capacity to induce hemostasis and are not effective in killing bacteria. In recent years, mesoporous bioactive glasses (MBGs) were found to be effective in inducing hemostasis. However, the materials may not be considered as ideal hemostats since they do not offer antimicrobial activity. The gallium ion (Ga⁺³) not only exhibits antibacterial properties but also accelerates the blood coagulation cascade. The aim of this study was to develop …

Chemical and Biochemical Engineering Faculty Research & Creative Works

Bioactive glasses may function as antimicrobial delivery systems through the incorporation and subsequent release of therapeutic ions. The aim of this study was to evaluate the antimicrobial properties of a series of composite scaffolds composed of poly (octanediol citrate) with increased loads of a bioactive glass that releases zinc (Zn²⁺) and gallium (Ga³⁺) ions in a controlled manner. The antibacterial activity of these scaffolds was investigated against both Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria. The ability of the scaffolds to release ions and the subsequent ingress of these ions into hard tissue was evaluated …

A bioactive glass (BG) in which Ga was substituted for Zn was formulated to investigate whether the ionic form of Ga can elicit effects similar to gallium nitrate. The ion release and pH of BG extracts were evaluated, as well as the in vitro cytocompatibility of extracts in contact with mouse fibroblasts and human osteoblasts. After incubation times of 1 year, the glass (TGa-1) containing the smaller Ga-addition (8 mol%) released the most sodium (Na) (1420 mg/L), silicon (Si) (221 mg/L), and Ga (1295 mg/L), while the glass (TGa-2) containing the larger Ga-addition (16 mol%), exhibited release levels between TGa-1, …

Inorganic Hemostats: The State-Of-The-Art And Recent Advances, Sara Pourshahrestani, Ehsan Zeimaran, Ivan Djordjevic, Nahrizul Adib Kadri, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

Hemorrhage is the most common cause of death both in hospitals and on the battlefield. The need for an effective hemostatic agent remains, since all injuries are not amenable to tourniquet use. There are many topical hemostatic agents and dressings available to control severe bleeding. This article reviews the most commonly used inorganic hemostats, subcategorized as zeolite and clay-based hemostats. Their hemostatic functions as well as their structural properties that are believed to induce hemostasis are discussed. The most important findings from in vitro and in vivo experiments are also covered.

Materials Science and Engineering Faculty Research & Creative Works

The therapeutic potential of RNA interference (RNAi) has been limited by inefficient delivery of short interfering RNA (siRNA). Tumor-specific recognition can be effectively achieved by antibodies directed against highly expressed cancer cell surface receptors. We investigated the utility of linking an internalizing streptavidinconjugated HER2 antibody to an endosome-disruptive biotinylated polymeric nanocarrier to improve the functional cytoplasmic delivery of siRNA in breast and ovarian cancer cells in vitro and in an intraperitoneal ovarian cancer xenograft model in vivo, yielding an 80% reduction of target mRNA and protein levels with sustained repression for at least 96 hours. RNAi-mediated site specific cleavage …

Role Of Composition And Structure On The Properties Of Metal/Multifunctional Ceramic Interfaces, Fang Yin Lin, Aleksandr V. Chernatynskiy, Juan Claudio Nino, Jacob L. Jones, Richard G. Hennig, Susan Sinnott

Physics Faculty Research & Creative Works

The formation of intermetallic secondary phases, such as Pt₃Pb, has been observed experimentally at PbTiO₃/Pt and Pb(Zr,Ti)O₃/Pt, or PZT/Pt, interfaces. Density functional theory calculations are used here to calculate the work of adhesion of these interfacial systems with and without the secondary intermetallic phase. The charge density maps of the interfaces reveal the electronic interactions at the interface and the impact of the secondary phase. In addition, Bader charge analysis provides a quantitative assessment of electron transfer from the perovskites to the Pt. Analysis of the band diagrams indicates an increase of the potential …

A Spatial-Dynamical Framework For Evaluation Of Satellite Rainfall Products For Flood Prediction, Felipe Quintero, Witold F. Krajewski, Ricardo Mantilla, Scott Small, Bong Chul Seo

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Rainfall maps that are derived from satellite observations provide hydrologists with an unprecedented opportunity to forecast floods globally. However, the limitation of using these precipitation estimates with respect to producing reliable flood forecasts at multiple scales are not well understood. To address the scientific and practical question of applicability of space-based rainfall products for global flood forecasting, a data evaluation framework is developed that allows tracking the rainfall effects in space and time across scales in the river network. This provides insights on the effects of rainfall product resolution and uncertainty. Obtaining such insights is not possible when the hydrologic …

The Onset Of Electron-Induced Proton-Transfer In Hydrated Azabenzene Cluster Anions, Yi Wang, Xinxing Zhang, Svetlana Lyapustina, Michael M. Nilles, Shoujun Xu, Jacob D. Graham, Kit H. Bowen, John T. Kelly, Gregory S. Tschumper, Nathan I. Hammer

Chemistry Faculty Research & Creative Works

The prospect that protons from water may be transferred to N-heterocyclic molecules due to the presence of an excess electron is studied in hydrated azobenzene cluster anions using anion photoelectron spectroscopy and computational chemistry. In the case of s-triazine (C₃H₃N₃), which has a positive adiabatic electron affinity, proton transfer is not energetically favored nor observed experimentally. Heterocyclic rings with only 1 or 2 nitrogen atoms have negative electron affinities, but the addition of solvating water molecules can yield stable negative ions. In the case of the diazines (C₄H₄N₂: …

Military Engagement And Forward Presence: Down But Not Out As Tools To Shape And Win, John R. Deni Dr.

Books, Monographs & Collaborative Studies

Military engagement and forward-based U.S. military forces offer decisionmakers effective and efficient mechanisms for maintaining American influence, deterring aggression, assuring allies, building tomorrow’s coalitions, managing the challenge of disorder in the security environment, mitigating the risk of a major interstate war, and facilitating U.S. and coalition operations should deterrence fail. Unfortunately, significant cuts to overseas permanent presence and continuing pockets of institutional bias against engagement as a force multiplier and readiness enhancer have combined to limit the leverage possible through these two policy tools. Instead, reliance on precision strike stand-off capabilities and a strategy of surging American military might from …

Forgotten Fashions: Feather Pelerines Of The Nineteenth Century, Anna Rose Keefe

Open Access Master's Theses

Feather pelerine capes are featured in publications as collection highlights of the Victoria and Albert Museum, the British Museum, and Historic New England and described as superlative examples of the nineteenth century’s fascination with exotic fauna and the natural world. Made from three-quarter circles of undyed cotton, the capes are lined with down and covered in peacock, pheasant, and fowl feathers arranged in geometric and floral patterns. All the text surrounding feather pelerines is clear about one thing: there is no scholarly consensus on where these capes came from or who made them.

Research outputs 2014 to 2021

There is widespread interest among discipline-based science education researchers to situate their research in the existing scholarly literature base. Unfortunately, traditional approaches to conducting a thorough literature review are unduly hindered in astronomy education research as the venues in which scholarship is reported are fragmented and widely dispersed across journals of varying disciplines. The international STudies of Astronomy education Research (iSTAR) online repository is the result of a concerted international community effort to collect and categorize existing research from peer-reviewed journal articles, dissertations/theses, and grey literature. In a “first light” survey of over 300 U.S. dissertations, we find: (i) work …

The Integration Of Internal And External Training Load Metrics In Hurling, Shane Malone, Dominic Doran, Ibrahim Akubat Ibrahim Akubat, Kieran Collins

Articles

The current study aimed to assess the relationship between the hurling player’s fitness profile and integrated training load (TL) metrics. Twenty-five hurling players performed treadmill testing for VO2max, the speed at blood lactate concentrations of 2 mmol•L-1 (vLT) and 4 mmol•L-1 (vOBLA) and the heart rate-blood lactate profile for calculation of individual training impulse (iTRIMP). The total distance (TD; m), high speed distance (HSD; m) and sprint distance (SD; m) covered were measured using GPS technology (4-Hz, VX Sport, Lower Hutt, New Zealand) which allowed for the measurement of the external TL. The external TL was divided by the internal …

Mahon, Sean Doyle, Minu Shinoy

Articles

Burkholderia cepacia complex (Bcc) causes chronic opportunistic lung infections in people with cystic fibrosis (CF) resulting in a gradual lung function decline and, ultimately, patient death. Bcc is a complex of eighteen species and is rarely eradicated once a patient is colonised, therefore vaccination may represent a better therapeutic option. We developed a new proteomics approach to identify bacterial proteins that are involved in attachment of Bcc to lung epithelial cells. Fourteen proteins were reproducibly identified by 2-DE from four Bcc strains, representative of two Bcc species: B. cenocepacia, the most virulent and B. multivorans, the most frequently acquired. Seven …

Flirting Online And The Connection Between The Use Of Dating Websites And Dating Applications, Kristine Johnson, Olguta Vilceanu, Manuel C. Pontes

AMTP Proceedings 2016

For this research, we used data collected by the Pew Foundation's "Internet and American Life Project Tracking Survey," conducted in Spring 2013. The data was adjusted through the use of sampling weights to estimate for general population parameters. The collected data examined online flirting, use of dating websites, and the use of dating apps. Findings suggest women between the ages of 18-34 years are just as likely as men to signal their romantic interest by engaging in online flirtation. In addition, women ages 50 years or older are less likely than men to signal their romantic interest by engaging in …

Linear, Narrative-Plot Development In The Song Of Songs—Part One, Richard M. Davidson

Faculty Publications

This article examines the linear, narrative-plot development in the Song of Songs. Evidence is first given supporting several hermeneutical presuppositions which underpin this study: (1) the unity of the Song, revealed especially in its exquisitely designed symmetrical literary macrostructure; (2) Solomonic authorship of the Song, written early in his reign while he was still monogamous; (3) King Solomon and Pharaoh’s daughter (Shulamit) as the couple in the Song; and (4) a literal (not allegorical) interpretation of the Song as human love poetry. Building upon these presuppositions, this article explores text-indicators for the historical narrative-plot progression of the Song, building largely …

When We Grade Students’ Proofs, Do They Understand Our Feedback?, Robert C. Moore, Martha Byrne, Sarah Hanusch, Timothy Fukawa-Connelly

Faculty Publications

Instructors often write feedback on students’ proofs even if there is no expectation for the students to revise and resubmit the work. It is not known, however, what students do with that feedback or if they understand the professor’s intentions. To this end, we asked eight advanced mathematics undergraduates to respond to professor comments on four written proofs by interpreting and implementing the comments. We analyzed the student’s responses using the categories of corrective feedback for language acquisition, viewing the language of mathematical proof as a register of academic English.

Inefficiently Automated Law Enforcement, Woodrow Hartzog, Gregory Conti, John Nelson, Lisa A. Shay

Faculty Scholarship

For some crimes the entire law enforcement process can now be automated. No humans are needed to detect the crime, identify the perpetrator, or impose punishment. While automated systems are cheap and efficient, governments and citizens must look beyond these obvious savings as manual labor is replaced by robots and computers. Inefficiency and indeterminacy have significant value in automated law enforcement systems and should be preserved. Humans are inefficient, yet more capable of ethical and contextualized decision-making than automated systems. Inefficiency is also an effective safeguard against perfectly enforcing laws that were created with implicit assumptions of leniency and discretion. …
