First Arkansas Records Of The True Bugs Lasiochilus Hirtellus (Hemiptera: Heteroptera: Lasiochilidae) And Physopleurella Mundula (Anthocoridae)., S. W. Chordas Iii, R. Tumlison

Journal of the Arkansas Academy of Science

We report 2 uncommon species of true bugs (Hemiptera: Heteroptera), Lasiochilus hirtellus (Lasiochilidae) and Physopleurella mundula (Anthocoridae), for the first time from Arkansas. This includes the first report of the family Lasiochilidae for Arkansas. Both species were captured in UV light traps set in Clark County. We discuss identification, provide digital images of the voucher specimens and include updated distribution maps (north of Mexico) for both species. With the addition of these 2 species, there are now a total of 7 anthocorid species, among the 3 bug families Lasiochilidae, Anthocoridae and Lytocoridae, known for Arkansas.

Foxo1 Inhibition And Fadd Knockdown Have Opposing Effects On Anticancer Drug-Induced Cytotoxicity And P21 Expression In Osteosarcoma Cells, Danielle Walker, Antanay Hall, Alexis Bonwell, Nancy Gordon, Danielle Robinson, Mario G Hollomon

Faculty, Staff and Student Publications

Forkhead box class O1 (FOXO1) and fas-associated death domain (FADD) regulate cell death pathways and homeostatic processes such as cell cycle progression and apoptosis. FADD phosphorylation promotes nuclear localization of FOXO1, and FOXO1 regulates FADD expression. Therefore, it is plausible that FOXO1 and FADD have synergistic or antagonistic effects on cell cycle regulation and the response to anticancer drug treatment in cancer cells. In the present study, we report that AS1842856-mediated inhibition of FOXO1 reverses anticancer drug-induced cytotoxicity, while FADD knockdown increases anticancer drug-induced cytotoxicity in osteosarcoma (OS). Reversed anticancer drug-induced cytotoxicity was accompanied by G2/M cell cycle arrest and …

Premature Aging In Serious Mental Illness, Breno S Diniz, Gabriel R Fries, Chia-Ling Kuo, Ming Xu, Eric J Lenze

Faculty, Staff and Student Publications

Serious mental illnesses (SMIs), including major depressive disorder, bipolar disorder, and schizophrenia, have long been linked to cognitive decline, multiple chronic medical conditions, and premature mortality. These factors significantly contribute to the severe disability seen in SMIs, extending beyond the severity of psychopathology and indicating a premature aging phenotype associated with these conditions. The mechanisms that underlie the relationship between SMIs and the premature aging phenotype are not well understood, but recent evidence suggests that individuals with SMIs may exhibit accelerated biological aging. In this review, we present a comprehensive analysis of the current literature, demonstrating the potential association of …

Conflict And Community Building In Waste Water Management: The Case Of Azrou Morocco, Jack V. Kalpakian

Peace and Conflict Studies Journal Conference

Climate change is forcing Morocco to institute a wide program of wastewater treatment. Despite legal and bureaucratic problems, the water is being reused directly or indirectly. But the construction of water treatment plants is leading to conflicts with farmers that depended on the untreated water and the use of treated water for green spaces and parks is also often viewed with suspicion. Using the case of the Azrou water treatment plant, this paper argues that while the infrastructure and technical adjustments to climate change have been effective, a gap in understanding between the water managers and the public they serve …

Wavelet-Based Mechanomyographic Intensity Responses To Sustained Tasks Anchored To Low Versus High Ratings Of Perceived Exertion, Dolores G. Ortega, Robert W. Smith, Jocelyn E. Arnett, Tyler J. Neltner, Trevor D. Roberts, Justin S. Pioske, Richard J. Schmidt, Terry J. Housh

Journal for Sports Neuroscience

Purpose: This study examined the effects of sustained, isometric forearm flexion tasks anchored to ratings of perceived exertion of 2 (RPE2_FT) versus 8 (RPE8_FT) on the wavelet-based mechanomyographic (MMG) intensity responses from pretest and posttest maximal voluntary isometric contractions (MVICs) as well as the time course of changes in the MMG intensity responses throughout the sustained tasks. Methods: Eleven men (mean±SD: age=20.9±2.3 yrs) performed MVICs before and after the sustained tasks. The wavelet analyses decomposed the MMG signals onto a set of 11 wavelet bands (WBs). Repeated measures ANOVAs were used to analyze the MMG intensity …

Global Deep-Sea Hydrothermal Deposit Metagenomes And Metagenome-Assembled Genomes Over Time And Space, Emily St John, Anna-Louise Reysenbach

Center for Life in Extreme Environments Publications

Actively venting high temperature deep-sea hydrothermal vent deposits along tectonic spreading centers and in backarc basins harbor a rich diversity of thermophilic Bacteria and Archaea, many of which have no representatives in cultivation nor any genomic representation in databases. Here, in order to produce a global-scale time series metagenomic resource for studying the microbial functional and genomic diversity in these high temperature ecosystems, we obtained 70 metagenomes from collections across spatial and temporal gradients from 21 different vent fields spanning 16 years (1993-2009). The dataset (Deep-Sea Hydrothermal Vent dataset (DSV70)) includes 3.56 Tbp of raw DNA sequence reads, that have …

Aging of the blood system impacts systemic health and can be traced to hematopoietic stem cells (HSCs). Despite multiple reports on human HSC aging, a unified map detailing their molecular age-related changes is lacking. We developed a consensus map of gene expression in HSCs by integrating seven single-cell datasets. This map reveals previously unappreciated heterogeneity within the HSC population. It also links inflammatory pathway activation (TNF/NFκB, AP-1) and quiescence within a single gene expression program. This program dominates an inflammatory HSC subpopulation that increases with age, highlighting a potential target for further experimental studies and anti-aging interventions.

Theoretical Analysis Of Mir-Based Differential Photoacoustic Spectroscopy For Noninvasive Glucose Sensing, Tasnim Ahmed, Khan Mahmud, Md Rejvi Kaysir, Shazzad Rassel, Dayan Ban

Electrical and Computer Engineering Faculty Research

Diabetes is a developing global health concern that cannot be cured, necessitating frequent blood glucose monitoring and dietary management. Photoacoustic Spectroscopy (PAS) in the mid-infrared (MIR) region has recently emerged as a viable noninvasive blood glucose monitoring technique. However, MIR-PAS confronts significant challenges: (i) Water absorption, which reduces light penetration, and (ii) interference from other blood components. This paper systematically analyzes the background of photoacoustic signal generation and proposes a differential PAS (DPAS) in the MIR region for removing the background signals arising from water and other interfering components of blood, which improves the overall detection sensitivity. A detailed mathematical …

The Ethical Limits Of Physician Autonomy In Reproductive Medicine, Isabel Martens

Honors Theses

In vitro fertilization is a relatively new medical practice that helps people who face infertility be able to reproduce. Reproductive medicine providers face ethical dilemmas often in their field, only some of which have standards of care. There are questions in the medical landscape pertaining to physician autonomy versus patient autonomy, which heavily apply to reproductive medicine providers. Patient autonomy is highly valued in medical ethics; however, physician autonomy should also be considered. When a physician decides who can and cannot reproduce, ethical considerations must be followed to maintain the practice of reproductive autonomy. Limited policies exist that manage reproductive …

Optimal Murine Cd4+ T Cell Priming By Mrna-Lipid Nanoparticle Vaccines Requires Endogenous Antigen Processing, Julia E. Rood, Suh Kyung Yoon, Mary K. Heard, Stephen D. Carro, Emma J.

Lipid nanoparticle (LNP)-encapsulated nucleoside-modified mRNA vaccines elicit robust CD4+ T cell responses, yet the mechanisms underlying this T cell priming remain unknown. Antigens presented to CD4+ T cells on major histocompatibility complex class II (MHC II) are traditionally acquired by antigen presenting cells (APCs) from extracellular sources. Here we show that vaccine specific CD4+ T cell responses instead rely on antigen directly expressed within APCs, without extracellular transit. Murine APCs treated with mRNA-LNP vaccines activate T cells more efficiently when presenting antigen produced internally, rather than acquired externally. Immunization with mRNA-LNP vaccines engineered to inhibit antigen expression in APCs results …

Purpose: RAPGEF2 encodes a guanine nucleotide exchange factor (GEF) that activates small GTPases and has not been linked to a Mendelian disorder. RAPGEF2 is highly intolerant to loss-of-function variants. We report 5 de novo heterozygous variants in RAPGEF2 in unrelated individuals with developmental delay, attention deficit hyperactivity disorder, epilepsy, dysmorphic features, or other manifestations. We used a Drosophila model to assess the functional impact of the identified human variants.

Methods: We generated a Kozak-GAL4 null allele of the Drosophila ortholog of RAPGEF2, PDZ-GEF, and used the allele to determine the gene expression pattern as well as the loss-of-function phenotypes. We …

Ai Derivation And Exploration Of Antibiotic Class Spaces, Adam Bess, Sean Rowland, Chris Alvin, Supratik Mukhopadhyay

Open Access Fund Publications

Purpose The rapid evolution of antibiotic-resistant bacteria poses an urgent global health crisis. A key gap in current antibiotic discovery approaches is the absence of automated chemical synthesis methods designed to systematically generate and evaluate compounds within specific antibiotic classes. We address this gap through fragment-based computational experiments that systematically explore antibiotic chemical spaces.

Methods Our computational methodology consists of three steps: fragmentation of known compounds (eMolFrag), generating new molecular structures by recombining fragments (eSynth), and filtering of candidates based on desired properties (eFilter). eFilter combines structural analysis, pathway information, and protein targets …

Fda's New Approval Plan For Covid-19 Vaccines: An Inquiry Of "Benefit" Rather Than The Statutory Scope Of "Safety, Purity, And Potency"?, Henry Yat-Shing Kwan

Journal of Law and Health

This article analyzes the FDA's proposed policy plan issued in May 2025 regarding the approval of Covid-19 boosters for different groups of persons. It offers two constructive recommendations that will help prevent constitutionality challenge on impermissible intrusion of the freedom of health.

The first is to avoid using the confusing term "benefit" but instead focus on the statutory parameters of "safety, purity, and potency." The affected group can make a strong case that their free choice of vaccination should not be deprived, as long as the vaccine qualifies for the statutory thresholds of being safe, pure, and potent. They are …

Patent Pending: How The Current Patent Utility Requirement Hinders Biotechnological Innovation, Madison Drlik

Journal of Law and Health

The legal system is always playing catch up to adapt to new legal landscapes, doctrines, and technology; however, patent law needs help to compete with biotechnological research in the race towards innovation. Biotechnological research in the realm of human health and medicine often involves the use of therapeutic drugs. The field of healthcare biotechnology takes biological systems and processes and generates novel, creative solutions to a number of human health conditions. However, the translation process for a new drug, therapy, or process is long and expensive which requires investors to help the researchers and scientists move their creations from inception …

Department of Neurology Faculty Papers

Introduction Single-cell RNA sequencing has elucidated the heterogeneity in cancer. Single-cell glioblastoma (GBM) analyses have also proposed the resemblance of GBM cells to radial glia and outer radial glia (oRG) supporting the hypothesis that remnants of developmental tissue get reactivated in cancer. A recent study isolated neural progenitor cells (NPCs) from developing fetal human brain (gestational week 17-19) and classified NPCs based on their expression of THY1 (CD90), CD24 and EGFR. Ventricular radial glia are THY1⁻CD24⁻EGFR⁺ whereas oRG are THY1⁻CD24⁻EGFR⁻. Early neuron precursors are CD24⁺THY1⁻EGFR …

Selective Deletion Of Slc2a1 From The Rpe Reveals That Rods But Not Cones Depend On Glucose Transport Across The Outer Blood-Retinal Barrier, Lauren L. Daniele, John Y.S. Han, Minzhong Yu, Ravi A. Sangani, Craig D. Beight, Cyrus Rostami, Philip D. Kiser, Neal S. Peachy, Nancy J. Philp

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

GLUT1 facilitates a continuous flow of glucose across the inner and outer blood-retinal barriers (BRBs) to support vision. To understand the extent to which photoreceptors rely on glucose transport across the outer BRB, we generated a tamoxifen-inducible conditional knockout of Slc2a1 in the retinal pigment epithelium (RPE) (RPE-iΔGlut1). In the RPE-iΔGlut1 mice, rod photoreceptors exhibited impaired outer segment renewal and decreased the expression of proteins involved in phototransduction and ciliary transport. Proteins regulating the retinal stress response increased. Cone photoreceptors were functional and viable 15 months post-tamoxifen treatment in the RPE-iΔGlut1 mice, while 70% of the rods died. …

Creating genetic sensors for noninvasive visualization of biological activities in optically opaque tissues holds immense potential for basic research and the development of genetic and cell-based therapies. Magnetic resonance imaging (MRI) stands out among deep tissue imaging methods for its ability to generate high-resolution images without ionizing radiation. However, the adoption of MRI as a mainstream biomolecular technology has been hindered by the lack of adaptable methods to link molecular events with genetically encodable contrast. Here, we introduce modular aquaporin-based protease-activatable probes for enhanced reporting (MAPPER), a platform for the systematic creation of genetic sensors for MRI. To develop MAPPER, …
