Newly synthesized ligand and their metal complexes were tested for their ability to scavenge free radicals at concentrations between 6.25 and 100 µg/ml using their interaction with the stable free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). It has been demonstrated that all compounds enhance antioxidant activity in …

Simultaneous Determination Of Lead And Cadmium In Environmental Samples Using Zinc-Diethyldithiocarbamates, Bashar Qasim

Baghdad Science Journal

Toxic metals have a serious impact on the ecological environment. The determination of these metal concentrations provides more information about their toxicity. In this study, a simple, rapid and selective spectrophotometric method with solid phase extraction method has been described for the simultaneous determination of lead (Pb) and cadmium (Cd) in environmental samples using a freshly precipitated zinc-diethyldithiocarbamate (Zn-(DDTC)2) as a reagent. The pre-concentration of Pb and Cd contents was performed according to solid phase extraction process. The determination of Pb+2 and Cd+2 based on the replacement of Zn+2 from the freshly precipitated Zn-(DDTC)2 by Pb+2 and Cd+2 in aqueous …

Comparison Of Surface-Enhanced Raman Scattering In Colloidal Silver Nanostar ‎And Colloidal Silver Nanocubes, Zinah Salahuddin Shakir, Sameer Khudhur Yaseen, Ayad Abdul Razzak Dhaigham

Baghdad Science Journal

Surface-enhanced Raman spectroscopy (SERS) is an extremely responsive and selective method that improves the Raman scattering signals of molecules utilizing nanomaterials as substrates. SERS enables the identification of material in very low concentrations via electrical field amplification or chemical enhancement due to the localized surface Plasmon (LSP). In this work, low concentrations of sodium sulfate (Na2SO4) were investigated as a water pollutant using liquid SERS based on colloidal Ag nanostructures. Two types of Ag nanostructures were prepared and utilized as liquid SERS substrates: nanostars (NSs) and nanocubes (NCs). A chemical reduction method was used for synthesizing Ag nanostructures from silver …

Academic Libraries, Counter-Storytelling, And Minoritized Students' Scholarly Identity Development, Darren Ilett

University Libraries Publications

This study uses the critical race theory approach of counter-storytelling to explore scholarly identity development among first-generation, low-income, BIPOC (Black, Indigenous, and People of Color), and women students transitioning to graduate school. Data included interview transcripts, observation notes, and student assignments from a program that supports students in completing an original research project and applying for graduate school. Findings show the frequent negative stereotypes about students that circulate in higher education as well as students' own counter-stories that reimagine academia and their place in it. Implications include ways that libraries can better support students' scholarly identity development.

Towards Understanding Capacity Development As A System: Perceptions From Multiple Conservation Stakeholder Groups In Bhutan, Jeremy S. Brooks, Sonam Wangyel Wang, Ugyen Namgyel, Jennifer Zavaleta Cheek, Katia Nakamura Lam, Johanna Eklund, Om Katel, Daniel C. Miller

Natural Resource Management Faculty Publications

Capacity development is crucial for enduring conservation success. Recent scholarship has called for a systems perspective based on input from local stakeholders to better understand and develop conservation capacity. However, few studies have adopted such an approach to explore interactions among capacities or how capacity development needs and priorities evolve. We address this gap through a case study from Bhutan, centred on perceptions from 52 local conservation practitioners, planners, funders and community members. We use mixed methods to identify which capacities have been important for conservation success, which capacities are needed for future success, which capacities are foundational and how …

Population Genetic Analysis Informs Dispersal Capacity In Representative Marine Trematodes From Family Microscaphidiidae And Family Paramphistomatidae, Randi Leigh Barton

Capstone Projects and Master's Theses

In marine and terrestrial systems, life history drives the distribution of organisms and informs the spatial scale of population connectivity. Nearly all bony reef fishes and invertebrates have a bipartite life cycle with a planktonic larval stage, which increases the organism’s dispersal capacity, and concludes with a relatively non-dispersive adult phase. While many studies have identified the relevant spatial scale for studying population structure in fishes and invertebrates, few have done the same for parasitic taxa, which have even more complex life histories with a higher diversity in the range of dispersal strategies they use. Parasite taxa differ in (1) …

Medical Students’ Self-Perceived Knowledge And Clinical Comfort With Genetics In Pakistan, Maheen Arshad, Angela Trepanier, S Shahrukh Hashmi, Rizwan Naeem, Saqib Mehmood, Myla Ashfaq

Faculty, Staff and Student Publications

Pakistan has a high rate of genetic disorders and neonatal mortality concurrent with noted lack of genetic counselors and geneticists. To meet the needs of the patient population, the responsibility of providing clinical genetic services falls on general and specialty physicians. However, their education regarding these essential services is not standardized in medical school curricula nor has it ever been evaluated. The purpose of this work is to describe the self-perceived knowledge, clinical comfort, and perspectives of Pakistani medical students toward their medical genetics' education. A web-based survey was distributed electronically to medical schools around the country. The survey comprised …

Molecular Architecture And Functional Dynamics Of The Pre-Incision Complex In Nucleotide Excision Repair, Jina Yu, Chunli Yan, Tanmoy Paul, Lucas Brewer, Susan E Tsutakawa, Chi-Lin Tsai, Samir M Hamdan, John A Tainer, Ivaylo Ivanov

Faculty, Staff and Student Publications

Nucleotide excision repair (NER) is vital for genome integrity. Yet, our understanding of the complex NER protein machinery remains incomplete. Combining cryo-EM and XL-MS data with AlphaFold2 predictions, we build an integrative model of the NER pre-incision complex(PInC). Here TFIIH serves as a molecular ruler, defining the DNA bubble size and precisely positioning the XPG and XPF nucleases for incision. Using simulations and graph theoretical analyses, we unveil PInC's assembly, global motions, and partitioning into dynamic communities. Remarkably, XPG caps XPD's DNA-binding groove and bridges both junctions of the DNA bubble, suggesting a novel coordination mechanism of PInC's dual incision. …

Superior Antitumor Immune Response Achieved With Proton Over Photon Immunoradiotherapy Is Amplified By The Nanoradioenhancer Nbtxr3, Yun Hu, Sébastien Paris, Narayan Sahoo, Qi Wang, Qianxia Wang, Hampartsoum B Barsoumian, Ailing Huang, Jordan Da Silva, Célia Bienassis, Claudia S Kettlun Leyton, Tiffany A Voss, Fatemeh Masrorpour, Thomas Riad, Carola Leuschner, Nahum Puebla-Osorio, Saumil Gandhi, Quynh-Nhu Nguyen, Jing Wang, Maria Angelica Cortez, James W Welsh

Faculty, Staff and Student Publications

Recent findings suggest that immunoradiotherapy (IRT), combining photon radiotherapy (XRT) or proton radiotherapy (PRT) with immune checkpoint blockade, can enhance systemic tumor control. However, the comparative efficacy of XRT and PRT in IRT remains understudied. To address this, we compared outcomes between XRT + αPD1 and PRT + αPD1 in murine αPD1-resistant lung cancer (344SQR). We also assessed the impact of the nanoparticle radioenhancer NBTXR3 on both XRT + αPD1 and PRT + αPD1 for tumor control and examined the tumor immune microenvironment using single-cell RNA sequencing (scRNAseq). Additionally, mice cured by NBTXR3 + PRT + αPD1 were rechallenged with …

Preventive Treatment With A Cd73 Small Molecule Inhibitor Enhances Immune Surveillance In K-Ras Mutant Pancreatic Intraepithelial Neoplasia, Lincoln N Strickland, Wendao Liu, Usama Hussein, Nicolette Mardik, Xian Chen, Tingting Mills, Lana A Vornik, Michelle I Savage, Shizuko Sei, John Clifford, Holger K Eltzschig, Powel H Brown, Zhongming Zhao, Florencia Mcallister, Jennifer M Bailey-Lundberg

Faculty, Staff and Student Publications

Immunoprevention is an emerging consideration for solid tumors, including pancreatic ductal adenocarcinoma (PDAC). We and others have shown that Kras mutations in genetic models of spontaneous pancreatic intraepithelial neoplasia (PanIN), which is a precursor to PDAC, results in CD73 expression in the neoplastic epithelium and some populations of infiltrating immune cells, including macrophages and CD8 T cells. CD73 is an ecto-enzyme that converts extracellular adenosine monophosphate to adenosine, a critical immune inhibitory molecule in PDAC. We hypothesized inhibition of CD73 would reduce the incidence of PanIN formation and alter the immune microenvironment. To test our hypothesis, we used the KrasG12D; …

Cerebrovascular Disease Is Associated With Alzheimer's Plasma Biomarker Concentrations In Adults With Down Syndrome, Andreas Engvig, Karl Trygve Kalleberg, Lars T. Westlye, Esten Høyland Leonardsen, Alzheimer’S Disease Neuroimaging Initiative Consortium

Neurology Faculty Publications

DNA methylation age (MA), brain age (BA), and frailty index (FI) are putative aging biomarkers linked to dementia risk. We investigated their relationship and combined potential for prediction of cognitive impairment and future dementia risk using the ADNI database. Of several MA algorithms, DunedinPACE and GrimAge2, associated with memory, were combined in a composite MA alongside BA and a data-driven FI in predictive analyses. Pairwise correlations between age- and sex-adjusted measures for MA (aMA), aBA, and aFI were low. FI outperformed BA and MA in all diagnostic tasks. A model including age, sex, and aFI achieved an area under the …

Introduction

The United States has the highest teen pregnancy rate and sexually transmitted infection rates among developed countries. One common approach that has been implemented to reduce these rates is abstinence-only-until-marriage programs that advocate for delaying sexual intercourse until marriage. These programs focus on changing adolescents' beliefs toward abstinence until marriage; however, it is unclear whether adolescents' beliefs about abstinence predict their sexual behavior, including sexual risk behavior (SRB). An alternative approach may be encouraging youth to delay their sexual debut until they reach the age of maturity, but not necessarily until marriage.

The Use Of Puffed Rice Biomaterial As An Insulation Layer: Characterization And Simulation Study, Nicolas Monje Mejia

Theses

Upon close examination in this study, the feasibility of utilizing puffed rice as an insulation layer for construction is explored. Regions that are warm and receive direct sunlight experience heightened temperatures, which can lead to structures trapping excessive heat, resulting in increased cooling demands, energy consumption, and higher costs all around. As revealed via findings from research conducted over time, puffed rice showcases immense prospects when employed as insulation considering its high level of percolation coupled with low thermal conductivity rates. Conversely, conventional materials tend to have better-quality properties like greater compressive strength than what one sees here, along with …

Shocking Sentences, John B. Meixner Jr.

Scholarly Works

Harsh recidivist sentencing penalties, like three-strikes laws, have been criticized heavily among both academics and practitioners on a number of different grounds. Most arguments focus on how sentences arising from these penalties are disproportionate—that there is no sensible relationship between the wrong committed and the sentence imposed. Those critiques are valid, but there’s another important problem with recidivist sentencing penalties that has been overlooked: they lead to sentences that are totally unexpected—indeed, shocking—to the defendants who face them. Many recidivist sentencing penalties cause large leaps in sentencing exposure that amount to exponential growth when compared with a defendant’s prior sentences. …

The Three Eras Of Australian Practice On Mpas: The Interaction Between National And International Law And Policy, Ethan Beringen, Nengye Liu, Michelle Mei Ling Lim

Research Collection Yong Pung How School Of Law

Australia has attempted to position itself as a world leader in Marine Protected Area (MPA) practice through leveraging its significant national MPA network as well as its heavy involvement in the creation of high seas MPAs in the Antarctic. However, the quality of Australia’s domestic and international MPA practice have separately been subject to similar and convincing critiques. Despite this, little research exists which highlights how these two levels of law-making may interact regarding MPAs. Hence, the question to be addressed is: ‘How does Australia’s domestic and international MPA practice interact?’ Through drawing upon middle power theory to characterise this …

Feral Donkey, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Donkeys (Equus asinus) were first imported in substantial numbers to Australia in 1866 by Sir Thomas Elder. They were used as pack and draught animals in outlying areas of Western Australia (WA) until the 1930s. They were eventually replaced by the motor vehicle, and unwanted donkeys were released to the wild, where they became feral. The first record of feral donkeys is from the Kimberley in the early 1930s, but it is possible they became feral much earlier.

Feral Goat, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The goat (Capra hircus) was one of the first animals to be domesticated, 8 to 10 thousand years ago. Archaeological work indicates the earliest attempts at domestication were in dry hills surrounding the Mediterranean basin. The ability of goats to utilise the coarse browse of mountainous areas made them suitable for domestication, in preference to sheep. With large-scale domestication of goats throughout the world, goats escaped and established feral goat herds on most continents. Overgrazing by goats has caused severe environmental damage, worldwide.

Goats arrived in Australia with the first fleet. They were introduced to many areas by early settlers …
