Multicomponent coupling reactions offer an excellent platform for the synthesis of diverse libraries of heterocyclic compounds. We have been working on the synthesis of novel heterocyclic small molecules utilizing reactions such as Baylis-Hillman reaction, Passerini reaction, Click reaction, reductive amination aldol condensation, etc.

In the current project, we prepared three series of heterocyclic compounds using Passerini and Baylis-Hillman reactions as key steps. Owing to the importance of heterocyclic chemistry in drug discovery and the ease of synthesis, the …

Mindfulness And Blood Pressure Across Demographics: Analyses From The Serenity Study, Gabrielle R. Chin

Theses and Dissertations

Mindfulness, as a state, trait, and training, is linked with myriad positive mental and physical health outcomes. Understanding the individual characteristics potentially influencing links between mindful traits, mindfulness training, and physical health, is therefore important, yet remains under-addressed. Utilizing data from the ongoing Serenity Study (NCT02371317), the current project examines if (1) at baseline, higher trait mindfulness relates to lower BP consistently as a function of demographics, (2) Mindfulness-Based Stress Reduction (MBSR) training lowers BP consistently across demographic subgroups and initial levels of trait mindfulness, and (3) if change in trait mindfulness following MBSR training correlates with change in BP …

Burden Of Disease In Pediatric Patients With Hypophosphatasia: Results From The Hpp Impact Patient Survey And The Hpp Outcomes Study Telephone Interview., Eric T. Rush, Scott Moseley, Anna Petryk

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Hypophosphatasia (HPP) is a rare, inherited, metabolic bone disease caused by deficient tissue-non-specific isoenzyme of alkaline phosphatase activity that manifests as a broad range of signs/symptoms, including bone mineralization defects and systemic complications. The burden of disease is poorly characterized, particularly in children. This study aimed to characterize the patient-reported burden of disease among children with HPP using two survey instruments: the HPP Impact Patient Survey (HIPS) and the HPP Outcomes Study Telephone interview (HOST).

METHODS: Between September 2009 and June 2011, pediatric patients (aged younger than 18 years) with HPP were recruited to participate in the study via …

A Novel Eye Tracking Paradigm For Indexing Social Avoidance-Related Behavior In Fragile X Syndrome, Jessica Klusek, Carly Moser, Joseph Schmidt, Leonard Abbeduto, Jane E. Roberts

Faculty Publications

Fragile X syndrome (FXS) is characterized by hallmark features of gaze avoidance, reduced social approach, and social anxiety. The development of therapeutics to manage these symptoms has been hindered, in part, by the lack of sensitive outcome measures. This study investigated the utility of a novel eye tracking paradigm for indexing social avoidance-related phenotypes. Adolescent/young adult-aged males with FXS (n=24) and typical development (n=23) participated in the study. Participants viewed faces displaying direct or averted gaze and the first fixation duration on the eyes was recorded as an index of initial stimulus registration. Fixation durations did …

Department of Family & Community Medicine Faculty Papers

Objective: People with serious mental illness (SMI) experience significant disparities in morbidity and mortality from preventable and treatable medical conditions. Women with SMI have low mammography screening rates. SMI, poverty, and poor access to care can have a significant effect on a woman’s opportunity to learn about and discuss breast cancer screening with health care providers. This study examines the feasibility pilot outcomes of mammography decision support and patient navigation intervention (DSNI) for women with SMI living in supportive housing settings. The primary research question was: Does the DSNI increase knowledge, promote favorable attitudes, and decrease decisional conflict relating to …

N-Glycosylation-Defective Splice Variants Of Neuropilin-1 Promote Metastasis By Activating Endosomal Signals, Xiuping Huang, Qing Ye, Min Chen, Aimin Li, Wenting Mi, Yuxin Fang, Yekaterina Y. Zaytseva, Kathleen L. O'Connor, Craig W. Vander Kooi, Side Liu, Qing-Bai She

Markey Cancer Center Faculty Publications

Neuropilin-1 (NRP1) is an essential transmembrane receptor with a variety of cellular functions. Here, we identify two human NRP1 splice variants resulting from the skipping of exon 4 and 5, respectively, in colorectal cancer (CRC). Both NRP1 variants exhibit increased endocytosis/recycling activity and decreased levels of degradation, leading to accumulation on endosomes. This increased endocytic trafficking of the two NRP1 variants, upon HGF stimulation, is due to loss of N-glycosylation at the Asn150 or Asn261 site, respectively. Moreover, these NRP1 variants enhance interactions with the Met and β1-integrin receptors, resulting in Met/β1-integrin co-internalization and co-accumulation on endosomes. This provides persistent …

Background

In 2014, Vietnam was the first Southeast Asian country to commit to achieving the World Health Organization’s 90–90-90 global HIV targets (90% know their HIV status, 90% on sustained treatment, and 90% virally suppressed) by 2020. This pledge represented further confirmation of Vietnam’s efforts to respond to the HIV epidemic, one feature of which has been close collaboration with the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR). Starting in 2004, PEPFAR supported community outreach programs targeting high-risk populations (people who inject drugs, men who have sex with men, and sex workers). To provide early evidence on program impact, …

Developing Drug Therapies: Cognitive Damage In Mice Following Brain Radiation, Rachel Yuska

The Journal of Purdue Undergraduate Research

Pediatric brain cancer patients are at a high risk for radiation-induced cognitive impairment due to white matter changes in the brain. Half of six-month radiotherapy survivors develop significant changes in white matter. Previous research has shown that a mouse model can be used to show similar cognitive and behavioral deficits in human patients. The purpose of this work is to evaluate the effectiveness of two drug therapies, Donepezil and 3,3-Diindolylmethane (DIM), that could be used to either protect the brain from radiation injury or cure the cognitive injury and behavioral deficits that result from whole-brain irradiation. This project consisted of …

Nanomaterial-Agrichemical Interactions: Association Of Environmental Herbicides With Two-Dimensional Graphene Nanoplatelets, Nudar A. Bhuiya

The Journal of Purdue Undergraduate Research

Atrazine and glyphosate are the two most common agricultural herbicides used in the United States. Both herbicides can move in the environment, which results in contamination of drinking water sources. Graphene nanoplatelets (GNPs) are an emerging nanoparticle with potential uses for the remediation of environmental contamination. The first aim of this study was to determine binding interactions between atrazine and GNPs to mimic a mixture composition. To determine binding interactions, GNPs with different functional groups (none, carboxylated, or aminylated) were evaluated. GNPs at concentrations of 0, 0.5, 1, 2, or 3 mg/ml were incubated with atrazine at 3 ppb (μg/L) …

Measures Of Fluid Loss During Surfing: A Preliminary Analysis In Recreational Surfers, Rudi A. Meir, Zachary James Crowley-Mchattan Dr, Lyndon O. Brooks, Blake Duncan, Christian Gorrie, Jeremy Sheppard

International Journal of Aquatic Research and Education

Surfing is a popular sport, but little is known about the extent to which recreational surfers experience fluid loss from this activity. The principal objective of this research was to estimate fluid loss during a surfing session through changes in pre- to post-session urine color (Ucol), urine osmolality (Uosm), and body mass (BM). Data were collected from 11 recreational surfers across 14 surf sessions conducted under various environmental (mean water temperature = 22.1 SD ± 2.3; range = 20-26^oC; air temperature range = 13.1-31.5^oC; relative humidity range = 37.5-88.1%) and surfing conditions (e.g. winter/summer, wave type, …

From Treading Water To Swimming Uphill: A Comprehensive And Innovative Assessment Program For Teaching Swimming In Belgian Primary Schools., Filip Roelandt

International Journal of Aquatic Research and Education

According to the World Health Organization (WHO), every child should learn to swim as a recognised life skill. Which swimming skill or stroke to learn first is not the most important question. What is important is to teach children to learn tasks or techniques which allow them to they feel safe. Emphasizing foundational principles of motor development and focusing on safety in and around the water are paramount. Beginning in 2016 school swimming lessons in Flanders (Belgium) were given a new focus in all educational institutions. Foundational competence tasks replaced the focus on acquiring competitive swimming strokes as the primary …

Stem Opportunities - High School 2019, Huey-Xian Kelly Wong, Madeleine Rauhauser, Annie Morgan Nelson

Honors Program: Expanded Learning Clubs

This publication details the lesson plan for the “Opportunities in STEM” club for the summer of 2019. This club began out of a desire to educate high school students about the opportunities and careers available in the science, technology, engineering, and mathematics fields. Often, students feel that the prospect of entering a STEM field is daunting and out of their grasp. What it means to be a scientist is often unclear, and students never consider opportunities out of the fear of the unknown, particularly when science is associated with complexity and difficulty. This lesson plan integrates experiments with a wealth …

Head Depth And Head Speed During Competitive Backstroke Ledge Starts, Wesley J. Manz, Joel T. Greenshields, Brian V. Wright, Curtis S. Goss, Benjamin C. Skutnik, Joel M. Stager

International Journal of Aquatic Research and Education

Recently, a commercially available starting ‘ledge’ designed to reduce foot slippage during the execution of the backstroke start was introduced in competitive swimming. For the purpose of identifying potential safety consequences, the present study investigated the effect of ledge use on head depths, speeds, and distances in backstroke starts of athletes with no prior or only novice familiarity of the ledge. Competitive backstroke starts were performed with and without ledges by high school-aged (14.5 to 19.2 yr, N = 61) swimmers in 1.52 m of water during a closed testing session. A SIMI Reality Motion System in a calibrated space …

Advances In Gene Ontology Utilization Improve Statistical Power Of Annotation Enrichment, Eugene Waverly Hinderer Iii, Robert M. Flight, Rashmi Dubey, James N. Macleod, Hunter N. B. Moseley

Maxwell H. Gluck Equine Research Center Faculty Publications

Gene-annotation enrichment is a common method for utilizing ontology-based annotations in gene and gene-product centric knowledgebases. Effective utilization of these annotations requires inferring semantic linkages by tracing paths through edges in the ontological graph, referred to as relations. However, some relations are semantically problematic with respect to scope, necessitating their omission or modification lest erroneous term mappings occur. To address these issues, we created the Gene Ontology Categorization Suite, or GOcats—a novel tool that organizes the Gene Ontology into subgraphs representing user-defined concepts, while ensuring that all appropriate relations are congruent with respect to scoping semantics. Here, we demonstrate the …

Equine Or Porcine Synovial Fluid As A Novel Ex Vivo Model For The Study Of Bacterial Free-Floating Biofilms That Form In Human Joint Infections, Jessica M. Gilbertie, Lauren V. Schnabel, Noreen J. Hickok, Megan E. Jacob, Brian P. Conlon, Irving Shapiro, Javad Parvizi, Thomas P. Schaer

Department of Orthopaedic Surgery Faculty Papers

Bacterial invasion of synovial joints, as in infectious or septic arthritis, can be difficult to treat in both veterinary and human clinical practice. Biofilms, in the form of free-floating clumps or aggregates, are involved with the pathogenesis of infectious arthritis and periprosthetic joint infection (PJI). Infection of a joint containing an orthopedic implant can additionally complicate these infections due to the presence of adherent biofilms. Because of these biofilm phenotypes, bacteria within these infected joints show increased antimicrobial tolerance even at high antibiotic concentrations. To date, animal models of PJI or infectious arthritis have been limited to small animals such …

On The Fabrication And Development Of Tissue On A Chip Devices With Included Perfused Vasculatures, Usama Ismail

McKelvey School of Engineering Graduate Student Theses & Dissertations

The advent of Tissue-on-a-Chip (TiOC) devices has provided a novel way for researchers to approach biological study and drug development. As a platform that enables human in vivo conditions to be accurately replicated ex vivo, TiOC can accelerate both fundamental biological research to answer basic questions regarding tissue behavior and function (e.g., cell-cell interactions in the tumor microenvironment (TME)) and translational research that includes testing of standard and novel therapeutics. The reported work focuses on development of processes and technologies common to two classes of TiOC. The first device is a single-layer, multi-compartment microfluidic device for investigation of pancreatic …

United States Department of Agriculture Wildlife Services: Staff Publications

Field immobilization of native or invasive wild pigs (Sus scrofa) is challenging. Drug combinations commonly used often result in unsatisfactory immobilization, poor recovery, and adverse side effects, leading to unsafe handling conditions for both animals and humans. We compared four chemical immobilization combinations, medetomidine–midazolam–butorphanol (MMB), butorphanol–azaperone–medetomidine (BAM™), nalbuphine–medetomidine–azaperone (NalMed-A), and tiletamine– zolazepam–xylazine (TZX), to determine which drug combinations might provide better chemical immobilization of wild pigs. We achieved adequate immobilization with no post-recovery morbidity withMMB. Adequate immobilization was achieved with BAM™; however, we observed post-recovery morbidity. Both MMB and BAM™ produced more optimal results relative to body temperature, recovery, and …

Microrna And Mrna Interactions In Induced Pluripotent Stem Cell Reprogramming Of Lymphoblastoid Cell Lines, Satish Kumar, Erika C. Espinosa, Ana C. Leandro, Joanne E. Curran, John Blangero

School of Medicine Publications

A large number of Epstein Barr virus (EBV) immortalized lymphoblastoid cell lines (LCLs) have been generated and maintained in genetic/epidemiological studies as a perpetual source of DNA and as a surrogate in vitro cell model. Recent successes in reprograming LCLs into induced pluripotent stem cells (iPSCs) has paved the way to generate more relevant in vitro disease models using this existing bioresource. However, the latent EBV infection in the LCLs make them a unique cell type by altering expression of many cellular genes and miRNAs. These EBV induced changes in the LCL miRNome and transcriptome are reversed upon reprogramming into …
