An Alternative Strategy For Fabrication Of Robust And Flexible Digital Microfluidic Devices, Nathaniel Thorne, Melissa Lamberto, Audrey Mazza, Sergio Freire

International Journal of Undergraduate Research and Creative Activities

We present a new strategy for the fabrication of digital microfluidic (DMF) devices by research groups without access to well-equipped facilities. Compared to previously developed methods, it increases considerably device yield, and yet simplifies fabrication and enables flexible operation.To this end, we use large (260 and 400 μm) interelectrode gaps to optimize substrate fabrication, breaking the established constraint that gap dimensions must be small (usually < 150 μm) for digital microfluidics. In fact, we show that interelectrode gaps are not limiting features for DMF performance, and may be quite large (> 1 mm). Smooth droplet actuation is ensured by films of perfluoroalkoxy (PFA), which do not require additional coatings; films can be instantly replaced, without the necessity of annealing. Finally, our tests indicate that DMF devices …

The Effects Of Herbal Products In Cartilage Healing And Reducing The Progression Of Osteoarthritis, Mariya Baig, Mir Saleem

Mako: NSU Undergraduate Student Journal

Treatment for osteoarthritis (OA) includes symptom management with nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and acetaminophen. However, these drugs pose health risks for long-term use, such as contraindications and gastrointestinal/cardiovascular issues. This systematic review of the literature was conducted to evaluate the impact of the herbal products, turmeric and ginger, in cartilage healing and reducing the progression of OA. It was found that turmeric and ginger can aid in symptom management for OA and promote cartilage regeneration, with turmeric extract yielding greater evidence-based results. Turmeric reduces the amount of pain and stiffness experienced from OA and can restore cartilage by subduing …

Can The Use Of Art And Active Learning Improve Retention And Observational Skill Confidence Among Audiology Graduate Students, Aurora Weaver, Ashlyn Wheat, Travis Riffle, Chelsea Powell, Lindsey Leonard, Ryleigh Prickett, Anna Hill, Larry Molt

Teaching and Learning in Communication Sciences & Disorders

Human anatomy and physiology is considered one of the most difficult courses a student can take in a pre-health professional major in the US (Slominski, et. al., 2017). Research has revealed benefits of the use of art and anatomy within medical education, including improved clinical observational skills, greater understanding of disease and patient perspectives, and greater ability to empathize (Bell & Evans, 2014). Bell and Evans (2014) argue that observational skills are often overlooked in medical education. Use of art assignments in a graduate anatomy and physiology course will be discussed with reference to design and learning outcomes. The purpose …

A Multi-Modal Imaging Analysis Of Inter-Community Hub Nodes In Subjective Cognitive Decline Linking Longitudinal Hub Function Disruption To White Matter Integrity Kurtosis, Duncan Nowling

MUSC Theses and Dissertations

Subjective Cognitive Decline (SCD) has garnered much interest as a potential identifiable preclinical stage and indicator of risk for cognitive decline in Alzheimer’s Disease and related dementias (ADRD). Identification of individuals in this stage though is difficult, as they present with objectively normal cognitive evaluation scores, relying instead upon self-report of concern about decline in cognitive abilities. The use of non-invasive in-vivo imaging methods like BOLD functional imaging and diffusion tensor have allowed for complex mapping of both the functional and structural network features unique to this condition. This study furthers this network biomarker map of SCD by investigating the …

Butterfly Classification And Species Discovery Using Genomics, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Genomic sequencing of worldwide butterfly fauna followed by phylogenetic analysis of protein-coding genes informs butterfly classification throughout the taxonomic hierarchy, from families to species. As a rule, we attribute the same taxonomic rank to more prominent clades of comparable divergence (that is, at the same level in the tree). For species delimitation, we use criteria based on relative genetic differentiation and the extent of gene exchange between populations. We analyze the current taxonomic classification of butterflies in the light of genomic phylogenies and encounter clades that correspond to yet unnamed taxa. As a result, 11 tribes, 33 subtribes, 2 genera, …

The comprehensive assessment of long-term effects of reducing intake of energy (CALERIE-II; NCT00427193) clinical trial established that caloric restriction (CR) in humans lowers inflammation. The identity and mechanism of endogenous CR-mimetics that can be deployed to control obesity-associated inflammation and diseases are not well understood. Our studies have found that 2 years of 14% sustained CR in humans inhibits the expression of the matricellular protein, secreted protein acidic and rich in cysteine (SPARC), in adipose tissue. In mice, adipose tissue remodeling caused by weight loss through CR and low-protein diet feeding decreased, while high-fat diet-induced (HFD-induced) obesity increased SPARC expression …

The Development Of A One-Shot Learning Machine Learning For Industrial Use With Predictive Maintenance, Conor O Brien

Theses

With the advent of Industry 4.0, Manufacturing operations have become more connected and automated. Modern industrial monitoring technology can monitor the performance of both the sensor utilised and the material under monitoring. This has led to a trend where legacy machines without this technology are being removed from production and/or not included in new reconfigurations of production lines, well before their productive lifespan had ended. A key driver for this is the difficulty in retrofitting Predictive Maintenance (PdM) systems to legacy machines, in part due to the machine-to-machine variation present in older machines. Accounting for this variation in PdM systems …

Defending Against External Influences On Educational Data: The Role Of Policies And Procedures, Emily Faulconer, Debra Bourdeau

Publications

Within higher education, there has been increased focus over recent decades on evaluating our teaching practices to provide high-quality evidence of student learning for both internal and external assessment. Even at institutions without a college of education, many faculty are engaged in the scholarship of teaching and learning (SoTL) and/or discipline-based educational research (DBER). While studies are very diverse, and include qualitative and quantitative measures, common data points include student assessment scores and final course grades. In investigations using these measures, researchers acknowledge various mediating and moderating variables, but one particularly impactful variable is often ignored – administrative policies and …

Heterocyclic Merging Of Stereochemically Diverse Chiral Piperazines And Morpholines With Indazoles, Evan Lenkeit, Kevin R Mackenzie, Damian W Young, Srinivas Chamakuri

Faculty, Staff and Students Publications

We report a heterocyclic merging approach to construct novel indazolo-piperazines and indazolo-morpholines. Starting from chiral diamines and amino alcohols, novel regiochemically (1,3 and 1,4) and stereochemically diverse (relative and absolute) cohorts of indazolo-piperazines and indazolo-morpholines were obtained within six or seven steps. The key transformations involved are a Smiles rearrangement to generate the indazole core structure and a late-stage Michael addition to build the piperazine and morpholine heterocycles. We further explored additional vector diversity by incorporating substitutions on the indazole aromatic ring, generating a total of 20 unique, enantiomerically pure heterocyclic scaffolds.

Williamsii

Department of Agronomy and Horticulture: Faculty Publications

The rapid adoption of glyphosate-resistant crops at the end of the 20th century caused a simplification of weed management that relied heavily on glyphosate for weed control. However, the effectiveness of glyphosate has diminished. A greater understanding of trends related to glyphosate use will shed new light on weed adaptation to a product that transformed global agriculture. Objectives were to (1) quantify the change in weed control efficacy from postemergence (POST) glyphosate use on troublesome weeds in corn and soybean and (2) determine the extent to which glyphosate preceded by a preemergence (PRE) improved the efficacy and consistency of weed …

Pre-Radiotherapy Ctdna Liquid Biopsy For Risk Stratification Of Oligometastatic Non-Small Cell Lung Cancer, Nicholas P Semenkovich, Shahed N Badiyan, Pamela P Samson, Hayley B Stowe, Yun E Wang, Rachel Star, Siddhartha Devarakonda, Ramaswamy Govindan, Saiama N Waqar, Clifford G Robinson, Gregory Vlacich, Bruna Pellini, Aadel A Chaudhuri

2020-Current year OA Pubs

The optimal treatment paradigm for patients with oligometastatic non-small cell lung cancer (NSCLC) remains unclear. Some patients with oligometastatic disease experience prolonged remission after locally consolidative radiation therapy (RT), while others harbor micrometastatic disease (below limits of detection by imaging) and benefit from systemic therapy. To risk-stratify and identify the patients most likely to benefit from locally consolidative RT, we performed a multi-institutional cohort study of 1487 patients with oligometastatic NSCLC undergoing liquid biopsy analysis of circulating tumor DNA (ctDNA). In total, 1880 liquid biopsies were performed and approximately 20% of patients (n = 309) had ctDNA measured prior to …

Tipifarnib Potentiates The Antitumor Effects Of Pi3kα Inhibition In Pik3ca- And Hras-Dysregulated Hnscc Via Convergent Inhibition Of Mtor Activity, Alison E Smith, Douglas R Adkins, Et Al.

2020-Current year OA Pubs

UNLABELLED: Outcomes for patients with recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) are poor, with median overall survival (OS) ranging from 6 to 18 months. For those who progress on standard-of-care (chemo)immunotherapy, treatment options are limited, necessitating the development of rational therapeutic strategies. Toward this end, we targeted the key HNSCC drivers PI3K-mTOR and HRAS via the combination of tipifarnib, a farnesyltransferase (FTase) inhibitor, and alpelisib, a PI3Kα inhibitor, in multiple molecularly defined subsets of HNSCC. Tipifarnib synergized with alpelisib at the level of mTOR in PI3Kα- or HRAS-dependent HNSCCs, leading to marked cytotoxicity in vitro and tumor …

Kinome Reprogramming Is A Targetable Vulnerability In Esr1 Fusion-Driven Breast Cancer, Xuxu Gou, Shunqiang Li, Et Al.

2020-Current year OA Pubs

UNLABELLED: Transcriptionally active ESR1 fusions (ESR1-TAF) are a potent cause of breast cancer endocrine therapy (ET) resistance. ESR1-TAFs are not directly druggable because the C-terminal estrogen/anti-estrogen-binding domain is replaced with translocated in-frame partner gene sequences that confer constitutive transactivation. To discover alternative treatments, a mass spectrometry (MS)-based kinase inhibitor pulldown assay (KIPA) was deployed to identify druggable kinases that are upregulated by diverse ESR1-TAFs. Subsequent explorations of drug sensitivity validated RET kinase as a common therapeutic vulnerability despite remarkable ESR1-TAF C-terminal sequence and structural diversity. Organoids and xenografts from a pan-ET-resistant patient-derived xenograft model that harbors the ESR1-e6>YAP1 TAF …

Safety And Immunogenicity Of Live Viral Vaccines In A Multicenter Cohort Of Pediatric Transplant Recipients, Amy G Feldman, Stacy Postma, Janis Stoll, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Live vaccines (measles-mumps-rubella [MMR] and varicella-zoster virus [VZV]) have not been recommended after solid organ transplant due to concern for inciting vaccine strain infection in an immunocompromised host. However, the rates of measles, mumps, and varicella are rising nationally and internationally, leaving susceptible immunocompromised children at risk for life-threating conditions.

OBJECTIVE: To determine the safety and immunogenicity of live vaccines in pediatric liver and kidney transplant recipients.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study included select pediatric liver and kidney transplant recipients who had not completed their primary MMR and VZV vaccine series and/or who displayed nonprotective serum antibody …

Diagnostic Criteria For Identifying Individuals At High Risk Of Progression From Mild Or Moderate To Severe Alcohol Use Disorder, Alex P Miller, Emma C Johnson, Rebecca Tillman, Vivia V Mccutcheon, Kathleen K Bucholz, Arpana Agrawal, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Current Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) diagnoses of substance use disorders rely on criterion count-based approaches, disregarding severity grading indexed by individual criteria.

OBJECTIVE: To examine correlates of alcohol use disorder (AUD) across count-based severity groups (ie, mild, moderate, mild-to-moderate, severe), identify specific diagnostic criteria indicative of greater severity, and evaluate whether specific criteria within mild-to-moderate AUD differentiate across relevant correlates and manifest in greater hazards of severe AUD development.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study involved 2 cohorts from the family-based Collaborative Study on the Genetics of Alcoholism (COGA) with 7 sites …

Interplay Between Esr1/Pik3ca Codon Variants, Oncogenic Pathway Alterations And Clinical Phenotype In Patients With Metastatic Breast Cancer (Mbc): Comprehensive Circulating Tumor Dna (Ctdna) Analysis, Lorenzo Gerratana, Andrew A Davis, Katherine Clifton, Whitney L Hensing, Cynthia X Ma, Et Al.

2020-Current year OA Pubs

BACKGROUND: although being central for the biology and druggability of hormone-receptor positive, HER2 negative metastatic breast cancer (MBC), ESR1 and PIK3CA mutations are simplistically dichotomized as mutated or wild type in current clinical practice.

METHODS: The study analyzed a multi-institutional cohort comprising 703 patients with luminal-like MBC characterized for circulating tumor DNA through next generation sequencing (NGS). Pathway classification was defined based on previous work (i.e., RTK, RAS, RAF, MEK, NRF2, ER, WNT, MYC, P53, cell cycle, notch, PI3K). Single nucleotide variations (SNVs) were annotated for their oncogenicity through OncoKB. Only pathogenic variants were included in the models. Associations among …

Abemaciclib Is Effective In Palbociclib-Resistant Hormone Receptor-Positive Metastatic Breast Cancers, Juliana Navarro-Yepes, Nicole M Kettner, Xiayu Rao, Cassandra Santaella Bishop, Tuyen N Bui, Akshara Singareeka Raghavendra, Jing Wang, Aysegul A Sahin, Funda Meric-Bernstam, Kelly K Hunt, Senthil Damodaran, Debu Tripathy, Khandan Keyomarsi

Cyclin-dependent kinases 4/6 inhibitor (CDK4/6i) plus endocrine therapy (ET) is standard of care for patients with hormone receptor (HR)-positive, HER2-negative metastatic breast cancer (MBC). However, resistance to CDK4/6is plus ET remains a clinical problem with limited therapeutic options following disease progression. Different CDK4/6is might have distinct mechanisms of resistance, and therefore using them sequentially or targeting their differentially altered pathways could delay disease progression. To understand pathways leading to resistance to the CDK4/6is palbociclib and abemaciclib, we generated multiple in vitro models of palbociclib-resistant (PR) and abemaciclib-resistant (AR) cell lines as well as in vivo patient-derived xenografts (PDX) and ex …

Accurate tumor segmentation is required for quantitative image analyses, which are increasingly used for evaluation of tumors. We developed a fully automated and high-performance segmentation model of triple-negative breast cancer using a self-configurable deep learning framework and a large set of dynamic contrast-enhanced MRI images acquired serially over the patients' treatment course. Among all models, the top-performing one that was trained with the images across different time points of a treatment course yielded a Dice similarity coefficient of 93% and a sensitivity of 96% on baseline images. The top-performing model also produced accurate tumor size measurements, which is valuable for …

Intraperitoneal Paclitaxel Is A Safe And Effective Therapeutic Strategy For Treating Mucinous Appendiceal Adenocarcinoma, Ichiaki Ito, Abdelrahman M G Yousef, Saikat Chowdhury, Princess N Dickson, Zahra A Naini, Karianne G Fleten, Keith F Fournier, Natalie W Fowlkes, John Paul Shen

Faculty, Staff and Student Publications

Appendiceal adenocarcinomas (AAs) are a rare and heterogeneous mix of tumors for which few preclinical models exist. The rarity of AA has made performing prospective clinical trials difficult, which has partly contributed to AA remaining an orphan disease with no chemotherapeutic agents approved by the FDA for its treatment. AA has a unique biology in which it frequently forms diffuse peritoneal metastases but almost never spreads via a hematogenous route and rarely spreads to lymphatics. Given the localization of AA to the peritoneal space, intraperitoneal (IP) delivery of chemotherapy could be an effective treatment strategy. Here, we tested the efficacy …

Faculty, Staff and Student Publications

UNLABELLED: A greater understanding of molecular, cellular, and immunological changes during the early stages of lung adenocarcinoma development could improve diagnostic and therapeutic approaches in patients with pulmonary nodules at risk for lung cancer. To elucidate the immunopathogenesis of early lung tumorigenesis, we evaluated surgically resected pulmonary nodules representing the spectrum of early lung adenocarcinoma as well as associated normal lung tissues using single-cell RNA sequencing and validated the results by flow cytometry and multiplex immunofluorescence (MIF). Single-cell transcriptomics revealed a significant decrease in gene expression associated with cytolytic activities of tumor-infiltrating natural killer and natural killer T cells. This …

PF-06804103 is an anti-HER2 antibody–drug conjugate with auristatin payload. We evaluated its safety, tolerability, and antitumor activity in patients with advanced/unresectable or metastatic breast and gastric cancers. This multicenter, open-label, first-in-human, phase 1 study (NCT03284723) comprised dose escalation (P1) and dose expansion (P2). In P1, adults with HER2+ breast or gastric cancer received PF-06804103 0.15–5.0 mg/kg intravenously once/21 days (Q3W); in P2, patients with HER2+ or HER2-low (IHC 1+ or IHC 2+/ISH−) breast cancer received 3.0 or 4.0 mg/kg Q3W. The primary endpoints were dose-limiting toxicities (DLT) and safety (P1), and objective response rate (ORR) assessed using RECIST v1.1 (P2). …

Endocrine Therapy Synergizes With Smac Mimetics To Potentiate Antigen Presentation And Tumor Regression In Hormone Receptor-Positive Breast Cancer, Francisco Hermida-Prado, Yingtian Xie, Shira Sherman, Zsuzsanna Nagy, Douglas Russo, Zhengtao Chu, Marco Campisi, Minyue Chen, Agostina Nardone, Cristina Guarducci, Klothilda Lim, Alba Font-Tello, Irene Lee, Juana García-Pedrero, Israel Cañadas, Judith Agudo, Ying Huang, Tal Sella, Qingchun Jin, Nabihah Tayob, Elizabeth A Mittendorf, Sara M Tolaney, Xintao Qiu, Henry Long, William F Symmans, Jia-Ren Lin, Sandro Santagata, Isabelle Bedrosian, Denise A Yardley, Ingrid A Mayer, Edward T Richardson, Giacomo Oliveira, Catherine J Wu, Eugene F Schuster, Mitch Dowsett, Alana L Welm, David Barbie, Otto Metzger, Rinath Jeselsohn

Faculty, Staff and Student Publications

Immunotherapies have yet to demonstrate significant efficacy in the treatment of hormone receptor-positive (HR+) breast cancer. Given that endocrine therapy (ET) is the primary approach for treating HR+ breast cancer, we investigated the effects of ET on the tumor immune microenvironment (TME) in HR+ breast cancer. Spatial proteomics of primary HR+ breast cancer samples obtained at baseline and after ET from patients enrolled in a neoadjuvant clinical trial (NCT02764541) indicated that ET upregulated β2-microglobulin and influenced the TME in a manner that promotes enhanced immunogenicity. To gain a deeper understanding of the underlying mechanisms, the intrinsic effects of …
