Modulation Of Hypoxia-Induced Chemoresistance To Polymeric Micellar Cisplatin: The Effect Of Ligand Modification Of Micellar Carrier Versus Inhibition Of The Mediators Of Drug Resistance, Hoda Soleymani Abyaneh, Amir Hassan Soleimani, Mohammad Reza Vakili, Rania Soudy, Kamaljit Kaur, Francesco Cuda, Ali Tavassoli, Afsaneh Lavasanifar

Pharmacy Faculty Articles and Research

Hypoxia can induce chemoresistance, which is a significant clinical obstacle in cancer therapy. Here, we assessed development of hypoxia-induced chemoresistance (HICR) against free versus polymeric cisplatin micelles in a triple negative breast cancer cell line, MDA-MB-231. We then explored two strategies for the modulation of HICR against cisplatin micelles: a) the development of actively targeted micelles; and b) combination therapy with modulators of HICR in MDA-MB-231 cells. Actively targeted cisplatin micelles were prepared through surface modification of acetal-poly(ethylene oxide)-poly(-carboxyl-"-caprolactone) (acetal-PEO-PCCL) micelles with epidermal growth factor receptor (EGFR)-targeting peptide, GE11 (YHWYGYTPQNVI). Our results showed that hypoxia induced resistance against free and …

"It's A Precious Gift, Not To Waste": Is Routine Cross Matching Necessary In Orthopedics Surgery?: Retrospective Study Of 699 Patients In 9 Different Procedures, Obada Hasan, Eraj Khurshid Khan, Moiz Ali, Sadaf Sheikh, Anum Fatima, Haroon Ur Rashid

Section of Orthopaedic Surgery

Background: Orthopedic surgeries are usually associated with excessive blood loss which leads surgeons to overestimate need for blood transfusions and over ordering of blood. The cross matched blood, when not used, leads to the wastage of blood bank resources in terms of time, money and manpower. The objective of this study was to investigate the compliance to previously proposed MSBOS and to provide updated recommendations for all orthopedic procedures.
Methods: A retrospective analysis was conducted between 1st June 2015 and 31st May 2016. Patients admitted to the orthopedic surgery service for whom blood products were requested were included. Cross Match/Transfusion …

Cytoprotective Effects Of Natural Compounds Against Oxidative Stress, Jay Mehta, Srujana Rayalam, Xinyu Wang

PCOM Scholarly Works

Oxidative stress, an imbalance between reactive oxygen species and antioxidants, has been witnessed in pathophysiological states of many disorders. Compounds identified from natural sources have long been recognized to ameliorate oxidative stress due to their inherent antioxidant activities. Here, we summarize the cytoprotective effects and mechanisms of natural or naturally derived synthetic compounds against oxidative stress. These compounds include: caffeic acid phenethyl ester (CAPE) found in honey bee propolis, curcumin from turmeric roots, resveratrol abundant in grape, and 1-[2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl] imidazole (CDDO-Im), a synthetic triterpenoid based on naturally occurring oleanolic acid. Cytoprotective effects of these compounds in diseases conditions like cardiovascular …

Octo- And Nonagenarians' Outlook On Life And Death When Living With An Implantable Cardioverter Defibrillator: A Cross-Sectional Survey, Ingela Thylén, Debra K. Moser, Anna Strömberg

Nursing Faculty Publications

Background: Elderly individuals are increasingly represented among patients with implantable cardioverter defibrillators (ICD), but data describing life with an ICD are scarse among octo- and nonagenarians. Moreover, few studies have reported those elderly patients’ perspective on timly discussions concerning what shock deactivation involves, preferences on battery replacement, and their attitudes about turning off the ICD nearing end-of-life. Consequently, the aim of the study was to describe outlooks on life and death in octo- and nonagenarian ICD-recipients.

Methods: Participants were identified via the Swedish Pacemaker- and ICD-registry, with 229 octo- and nonagenarians (82.0 ± 2.2 years, 12% female) completing the survey …

Gene Gangs Of The Chloroviruses: Conserved Clusters Of Collinear Monocistronic Genes, Phillip Seitzer, Adrien Jeanniard, Fangrui Ma, James L. Van Etten, Marc T. Facciotti, David D. Dunigan

Nebraska Center for Virology: Faculty Publications

Chloroviruses (family Phycodnaviridae) are dsDNA viruses found throughout the world’s inland waters. The open reading frames in the genomes of 41 sequenced chloroviruses (330 + 40 kbp each) representing three virus types were analyzed for evidence of evolutionarily conserved local genomic “contexts”, the organization of biological information into units of a scale larger than a gene. Despite a general loss of synteny between virus types, we informatically detected a highly conserved genomic context defined by groups of three or more genes that we have termed “gene gangs”. Unlike previously described local genomic contexts, the definition of gene gangs requires only …

Evaluation Of Oral Function Before And After Frenectomy In Breastfed Infants Diagnosed With Tethered Oral Tissue, Cindy L. Parr

LSU Doctoral Dissertations

Assessment and treatment of tethered oral tissue, or tongue tie, vary within and across providers, resulting in inconsistent surgical and therapeutic outcomes. Assessment and treatment have historically focused on the anatomical (structural) underpinnings of tongue tie, as opposed to the physiological (functional) aspects that can affect daily activities. This is particularly noteworthy in the infant population in regards to breastfeeding. Clinical findings, however, suggest that connections exist between tongue tie and a variety of other oral functions that go beyond breastfeeding. The goal of this research was to examine a relatively small group of breastfed infants with tethered oral …

Exome Sequencing Identifies Gene Variants And Networks Associated With Extreme Respiratory Outcomes Following Preterm Birth, Aaron Hamvas, Rui Feng, Yingtao Bi, Fan Wang, Soumyaroop Bhattacharya, Jared Mereness, Madhurima Kaushal, C Michael Cotten, Philip L Ballard, Thomas J Mariani

Faculty, Staff and Student Publications

BACKGROUND: Previous studies have identified genetic variants associated with bronchopulmonary dysplasia (BPD) in extremely preterm infants. However, findings with genome-wide significance have been rare, and not replicated. We hypothesized that whole exome sequencing (WES) of premature subjects with extremely divergent phenotypic outcomes could facilitate the identification of genetic variants or gene networks contributing disease risk.

RESULTS: The Prematurity and Respiratory Outcomes Program (PROP) recruited a cohort of > 765 extremely preterm infants for the identification of markers of respiratory morbidity. We completed WES on 146 PROP subjects (85 affected, 61 unaffected) representing extreme phenotypes of early respiratory morbidity. We tested for …

“My Determination Is To Live”: Narratives Of African-American Women Who Have Lived With Hiv For 10 Or More Years, Sabrina Cherry, Kathleen Demarrais, Cheryl Keita, Marsha Davis, Joel Lee

The Qualitative Report

Exploring the experiences of African-American women who have lived with HIV for many years can inform public health practice on how to better serve high-risk populations along the care continuum. To understand the experiences of African-American women who are HIV positive, the researchers used a narrative approach to guide repeat interviews. Under a theoretical framework of Womanism, we interviewed six African-American women ages 48-66 (M=57) who have lived with HIV for 10 years or longer and conducted analyses of narrative to identify key themes. The primary themes were: recollecting early hardships, HIV infection, and diagnosis; embracing social support; surviving and …

Common Sense And Common Nonsense: A Conversation About Mental Attitudes, Science, And Society, Daniel S. Levine

Psychology Faculty Publications - Archive

Daniel S. Levine's Common Sense and Common Nonsense observes human decision making, ethics, and social organization as illuminated by the scientific disciplines of neural network theory, neuroscience, experimental psychology, and dynamical systems theory. It is a book whose aim is advocacy as well as research. Its goal is to use an understanding of our brains and minds to better operationalize Aldous Huxley's admonition to "try to be a little kinder." It wanders over examples from sociology, politics, economics, religion, literature, and many other fields but looks at all as examples of a few common themes. The "common nonsense" of the …

Health Effects Of Late-Career Unemployment, Maren Wright Voss, Lori L. Wadsworth, Wendy Birmingham, M. Beth Merryman, Lisa Crabtree, Kathy Subasic, Man Hung

Extension Research

Objective: Job loss has a demonstrated negative impact on physical and mental health. Involuntary retirement has also been linked to poorer physical and mental health outcomes. This study examined whether late-career unemployment is related to involuntary retirement and health declines postretirement. Method: Analysis was conducted using the 2000-2012 U.S. Health and Retirement Study (HRS) survey data with unemployment months regressed with demographic and baseline health measures on physical and mental health. Results: Individuals with late-career unemployment reported more involuntary retirement timing (47.0%) compared with those reporting no unemployment (27.9%). Late-career unemployment had no significant effect on self-reported physical health (β …

P-21 Activated Kinase As A Molecular Target For Chemoprevention In Diabetes, Kyle Dammann, Vineeta Khare, Clyde Coleman, Henrik Berdel, Christoph Gasche

Surgery Faculty Publications

Hypothesis: Anti-diabetic drugs modulate p-21 activated kinase (PAK) signaling. Introduction: Type 2 diabetes mellitus (T2DM) is a chronic inflammatory disease associated with increased cancer risk. PAK signaling is implicated in cellular homeostasis when regulated, and cancer when unrestrained. Recent reports provided a role for PAK signaling in glucose homeostasis, but the role of PAKs in the pathogenesis of T2DM is unknown. Here, we performed a mini-meta-analysis to explore if anti-diabetic drugs modify PAK signaling pathways, and provide insight regarding modulation of these pathways, to potentially reduce diabetes-associated cancer risk. Methods: PAK interacting partners in T2DM were identified using the online …

Department of Pathology and Laboratory Medicine

Esophageal squamous cell carcinoma (ESCC) is one of the aggressive malignancies and mechanisms underlying its pathogenesis remain unclear. Cyclooxygenase-2 (COX-2) enzyme system plays a crucial role in many gastrointestinal malignancies and is an important regulator of cell growth, proliferation, apoptosis, differentiation and transformation. More precise outcome of COX-2 in ESCC is less investigated. In this study we investigated the risk factors of ESCC and expression of COX-2 in Carcinoma in situ (CIS) and ESCC compared to normal esophageal mucosa. ESCC relationship to clinico-pathological parameters using immunohistochemistry was also part of this investigation. Current study was conducted in the Institute of …

The Impact Of Stuttering On Development Of Self-Identity, Relationships, And Quality Of Life In Women Who Stutter, Charn Nang, Deborah J. Hersh, Katie Milton, Su Re Lau

Research outputs 2014 to 2021

Purpose: The experiences of women who stutter have been underresearched. Clinicians have little guidance from the research literature on issues specific to women who stutter and are likely to have less clinical contact with this group than with men who stutter because of the higher prevalence of stuttering in men. This study explored the experiences of a small group of women who stutter with a particular focus on what the main current issues are and how gender may have influenced experiences with stuttering.

Method: This qualitative study involved recruitment of 9 women who stutter (aged 35-80 years) through a support …

Antibody Epitope Specificity For Dsdna Phosphate Backbone Is An Intrinsic Property Of The Heavy Chain Variable Germline Gene Segment Used, Tatjana Srdic-Rajic, Heinz Kohler, Vladimir Jurisic, Radmila Metlas

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Analysis of protein sequences by the informational spectrum method (ISM) enables characterization of their specificity according to encoded information represented with defined frequency (F). Our previous data showed that F(0.367) is characteristic for variable heavy chain (VH) domains (a combination of variable (V), diversity (D) and joining (J) gene segments) of the anti-phosphocholine (PC) T15 antibodies and mostly dependent on the CDR2 region, a site for PC phosphate group binding. Because the T15 dsDNA-reactive U4 mutant also encodes F(0.367), we hypothesized that the same frequency may also be characteristic for anti-DNA antibodies. Data obtained from an analysis of 60 spontaneously …

Dual Inhibition Of Bcl-2/Bcl-Xl And Xpo1 Is Synthetically Lethal In Glioblastoma Model Systems, Enyuan Shang, Yiru Zhang, Chang Shu, Chiaki Tsuge Ishida, Elena Bianchetti, Mike-Andrew Westhoff, Georg Karpel-Massler, Markus D. Siegelin

Publications and Research

XPO1 has recently emerged as a viable treatment target for solid malignancies, including glioblastoma (GBM), the most common primary malignant brain tumor in adults. However, given that tumors become commonly resistant to single treatments, the identification of combination therapies is critical. Therefore, we tested the hypothesis that inhibition of anti-apoptotic Bcl-2 family members and XPO1 are synthetically lethal. To this purpose, two clinically validated drug compounds, the BH3-mimetic, ABT263, and the XPO1 inhibitor, Selinexor, were used in preclinical GBM model systems. Our results show that inhibition of XPO1 reduces cellular viability in glioblastoma cell cultures. Moreover, addition of ABT263 significantly …

Role Of Genes In Obesity, Hanna Mathew, Mir Saleem

Biology Faculty Articles

Obesity is the outcome of an extreme difference between the energy intake and the energy expended, which leads to severe weight gain. The two main factors of obesity are environmental influences and genetics, but the extent of the genetic contribution to obesity continues to be unknown. Multiple studies using different tools have been used to support the significance of the genetic influence on obesity, such as twin and adoption studies, race/ethnicity, and mouse models. The use of mouse models has allowed for the greatest expansion of knowledge on the genetics behind obesity, and advancements continue to be made to this …

The Tetraspanin Cd82 Regulates Hematopoietic Stem Cell Fitness And Bone Marrow Retention, Chelsea Alyssa Kimiko Saito-Reis

Biomedical Sciences ETDs

The maintenance of the hematopoietic stem and progenitor cell (HSPC) population is critical to sustaining the adult blood and immune system throughout an organism’s lifespan. The bone marrow microenvironment plays a key role in the regulation of HSPC maintenance and functions. Previous work from our lab has identified the tetraspanin CD82 as an important modulator of HSPC interactions with the bone marrow niche. However, the mechanisms as to how CD82 contributes to the maintenance, trafficking and retention of HSPCs with the niche remained unclear. First, we investigated how CD82 promotes HSPC quiescence, homing and engraftment using a global CD82 knock …

This paper examines adaptive device use among two samples of U.S. adults aged 40 years and older with agerelated macular degeneration, diabetic retinopathy, glaucoma or cataracts from the 2008 and 2016 waves of the nationally-representative cross-sectional National Health Interview Survey (n=2875 and n=6233 respectively). Individuals who replied affirmatively to the question, “do you use any adaptive devices such as telescopic or other prescriptive lenses, magnifiers, large print or talking materials, CCTV, white cane or guide dogs?” were defined as adaptive device users. Descriptive statistics and logistic regression models of adaptive device use were estimated. The main regression models used 2008 …

Cornual Abscess Rupture: A Rare Etiology Of Acute Abdomen, Pooja Patil, Lannah L. Lua, Bobby Brar, Mary Froehlich, Petar Planinic

School of Medicine Faculty Research

Ruptured cornual abscess or pyometra can resemble other more common causes of acute abdomen, including appendicitis, diverticulitis, tubo-ovarian abscess, and perforated viscus. Despite its rarity, the diagnosis of ruptured pyometra should always be considered in females presenting with acute abdominal pain, particularly in the setting of a retained intrauterine device.

Using Spectral And Cross-Spectral Analysis To Identify Patterns And Synchrony In Couples' Sexual Desire, Matthew J. Vowels, Kristen P. Mark, Laura M. Vowels, Nathan D. Wood

Kinesiology and Health Promotion Faculty Publications

Sexual desire discrepancy is one of the most frequently reported sexual concerns for individuals and couples and has been shown to be negatively associated with sexual and relationship satisfaction. Sexual desire has increasingly been examined as a state-like construct that ebbs and flows, but little is known about whether there are patterns in the fluctuation of sexual desire. Utilizing spectral and cross-spectral analysis, we transformed 30 days of dyadic daily diary data for perceived levels of sexual desire for a non-clinical sample of 133 couples (266 individuals) into the frequency domain to identify shared periodic state fluctuations in sexual desire. …

Department of Psychology Faculty Scholarship and Creative Works

Disasters have substantial consequences for population mental health. We used Twitter to (1) extract negative emotions indicating discomfort in New York City (NYC) before, during, and after Superstorm Sandy in 2012. We further aimed to (2) identify whether pre- or peri-disaster discomfort were associated with peri- or post-disaster discomfort, respectively, and to (3) assess geographic variation in discomfort across NYC census tracts over time. Our sample consisted of 1,018,140 geo-located tweets that were analyzed with an advanced sentiment analysis called ”Extracting the Meaning Of Terse Information in a Visualization of Emotion” (EMOTIVE). We calculated discomfort rates for 2137 NYC census …
