Co-Localization Of Autophagy-Related Protein P62 With Cancer Stem Cell Marker Dclk1 May Hamper Dclk1'S Elimination During Colon Cancer Development And Progression., Badal Chandra Roy, Ishfaq Ahmed, Satish Ramalingam, Venkatakrishna Jala, Bodduluri Haribabu, Prabhu Ramamoorthy, John Ashcraft, Joseph Valentino, Shrikant Anant, Venkatesh Sampath, Shahid Umar

Manuscripts, Articles, Book Chapters and Other Papers

Autophagy may play a critical role in colon cancer stem cells (CCSCs)-related cancer development. Here, we investigate whether accumulation of infection/injury-induced CCSCs due to impaired autophagy influences colon cancer development and progression. When Apc++ mice were infected with Citrobacter rodentium (CR; 109CFUs), we discovered presence of autophagosomes with increases in Beclin-1, LC3B and p62 staining during crypt hyperplasia. Apc1638N/+ mice when infected with CR or subjected to CR+AOM treatment, exhibited increased colon tumorigenesis with elevated levels of Ki-67, β-catenin, EZH2 and CCSC marker Dclk1, respectively. AOM/DSS treatment of Apc1638N/+ mice phenocopied CR+AOM treatment as colonic tumors exhibited pronounced changes in …

2018-2019 Acip Immunization Updates: Highlights For Pharmacists, Laressa Bethishou, Luma Munjy, Jeff Goad

Pharmacy Faculty Articles and Research

"Vaccinations have significantly reduced the burden of infectious diseases, preventing almost 6 million deaths worldwide.^1,2 In the United States, vaccines have led to a decrease in incidence of vaccine-preventable illness, mortality, and disease sequelae.³ Despite the proven benefit of vaccines, misinformation and failure to vaccinate has led to outbreaks of vaccine-preventable diseases. As of December 29, 2018, 372 cases of measles (from 17 outbreaks) and 2251 cases of mumps were reported in the United States in 2018.^4,5 These outbreaks support the need for continued education of patients and active immunization by pharmacists."

Alterations In Phosphorylation Of Hepatocyte Ribosomal Protein S6 Control Plasmodium Liver Stage Infection., Elizabeth K K Glennon, Laura S Austin, Nadia Arang, Heather S Kain, Fred D Mast, Kamalakannan Vijayan, John D Aitchison, Stefan H I Kappe, Alexis Kaushansky

Articles, Abstracts, and Reports

Plasmodium parasites are highly selective when infecting hepatocytes and induce many changes within the host cell upon infection. While several host cell factors have been identified that are important for liver infection, our understanding of what facilitates the maintenance of infection remains incomplete. Here, we describe a role for phosphorylated ribosomal protein S6 (Ser235/236) (p-RPS6) in Plasmodium yoelii-infected hepatocytes. Blocking RPS6 phosphorylation prior to infection decreases the number of liver stage parasites within 24 h. Infected hepatocytes exhibit elevated levels of p-RPS6 while simultaneously abrogating the induction of phosphorylation of RPS6 in response to insulin stimulation. This is in contrast …

Abrogation Of Endogenous Glycolipid Antigen Presentation On Myelin-Laden Macrophages By D-Sphingosine Ameliorates The Pathogenesis Of Experimental Autoimmune Encephalomyelitis, Yi Ban, Wenjuan Dong, Lixing Zhang, Tian Zhou, Ahmad Sabri Altiti, Khaleel Ali, David R. Mootoo, Victoria A. Biaho, Timothy Hla, Yi Ren, Xiaojing Ma

Publications and Research

Background: Although myelin is composed of mostly lipids, the pathological role of myelin lipids in demyelinating diseases remains elusive. The principal lipid of the myelin sheath is b-galactosylceramide (b-Galcer). Its a-anomer (a-Galcer) has been demonstrated to be antigenically presented by macrophages via CD1d, a MHC class I-like molecule. Myelin, which is mostly composed of b-Galcer, has been long considered as an immunologically-inert neuron insulator, because the antigen-binding cleft of CD1d is highly a-form-restricted.

Results: Here, we report that CD1d-mediated antigenic presentation of myelin-derived galactosylceramide (Mye-GalCer) by macrophages contributed significantly to the progression of experimental autoimmune encephalomyelitis (EAE). Surprisingly, this presentation …

Identifying Areas With Disproportionate Local Health Department Services Relative To Opioid Overdose, Hiv And Hepatitis C Diagnosis Rates: A Study Of Rural Illinois, Collen Mcluckie, Mai T. Pho, Kaitlin Ellis, Livia Navon, Kelly Walblay, Wiley D. Jenkins, Christofer Rodriguez, Marynia A. Kolak, Yen-Tyng Chen, John A. Schneider, Whitney E. Zahnd

Faculty Publications

Background: U.S. rural populations have been disproportionately affected by the syndemic of opioid-use disorder (OUD) and the associated increase in overdoses and risk of hepatitis C virus (HCV) and human immunodeficiency virus (HIV) transmission. Local health departments (LHDs) can play a critical role in the response to this syndemic. We utilized two geospatial approaches to identify areas of discordance between LHD service availability and disease burden to inform service prioritization in rural settings.Methods: We surveyed rural Illinois LHDs to assess their OUD-related services, and calculated county-level opioid overdose, HIV, and hepatitis C diagnosis rates. Bivariate choropleth maps were created to …

Environmental Transmission Of Toxoplasma Gondii: Oocysts In Water, Soil And Food, Karen Shapiro, Lillian Bahia-Oliveira, Brent Dixon, Aurélien Dumètre, Luz A. De Wit, Elizabeth Vanwormer, Isabelle Villena

School of Veterinary and Biomedical Sciences: Faculty Publications

Toxoplasma gondii is a zoonotic protozoan parasite that can cause morbidity and mortality in humans, domestic animals, and terrestrial and aquatic wildlife. The environmentally robust oocyst stage of T. gondii is fundamentally critical to the parasite's success, both in terms of its worldwide distribution as well as the extensive range of infected intermediate hosts. Despite the limited definitive host species (domestic and wild felids), infections have been reported on every continent, and in terrestrial as well as aquatic environments. The remarkable resistance of the oocyst wall enables dissemination of T. gondii through watersheds and ecosystems, and long-term persistence in diverse …

Pharmaceutical Price Gouging: The Need For Direct Regulation On The Gray Market, Nicole Rende

Journal of Civil Rights and Economic Development

(Excerpt)

This Note proposes federal legislation that will ultimately shut down the Pharmaceuticals gray market. The federal government should directly regulate the gray market and the price gouging mechanisms used. Congress should pass the Fair Accountability and Innovative Research Drug Pricing Act of 2016, currently proposed. This Act will increase price transparency and provide a civil penalty for wrong doers. In addition to the passage of this Act, there needs to be a direct attack on the gray market by creating an act that does not allow companies to participate in these distributions and ultimately form monopolies. This act needs …

All Peer-Reviewed Publications

Objective: In Sub-Saharan Africa, there is an increase in trypanosome non-susceptibility to multiple trypanocides, but limited information on judicious trypanocide use is accessible to smallholder farmers and agricultural stakeholders in disease endemic regions, resulting in widespread multi-drug resistance. Huge economic expenses and the laborious nature of extensive field studies have hindered collection of the requisite large-scale prospective datasets required to inform disease management. We examined the efficacy of community-led data collection strategies using smartphones by smallholder farmers to acquire robust datasets from the trypanosomiasis endemic Shimba hills region in Kenya. We used Open Data Kit, an open-source smartphone application development …

Effect Of Environmental Factors And Residual Sanitizers On Survival And Attachment Of Indicator Organism And Human Pathogens On Fresh Produce, Vijay Singh Chhetri

LSU Doctoral Dissertations

A comprehensive understanding of the behavior of microbial contaminants on produce surfaces in agricultural farms and during post-harvest activities is essential for the development of produce safety risk management strategies. Our studies investigated the survival and the attachment of E. coli on watermelon surfaces in agricultural settings with different levels of vegetation, and the effect of residual sanitizers on the survival and the attachment of E. coli O157: H7 and L. monocytogenes on spinach leaves. The attachment strength (S_R) of the E. coli cells on watermelon surfaces significantly increased (P<0.05) from 0.04 to 0.99 in the first 24 h, which was primarily due to the decrease in loosely attached population, given that the population of strongly attached cells was constant. The daily die-off rate of E. coli ranged from -0.12 …

Improving Coupled Enzyme Assays With Capillary Electrophoresis, Thu Hoai Nguyen

LSU Doctoral Dissertations

The goal of this project is to address limitations of coupled enzyme assays using capillary electrophoresis (CE). In some enzyme assays, it is ineffective to directly detect products and substrates spectroscopically (absorption or fluorescence). Coupling the enzyme-catalyzed reaction of interest with another enzyme-catalyzed reaction allows for indirect detection of product formation or substrate depletion for the target enzyme. While conventional coupled enzyme assays are facile for kinetic measurements, they can be problematic for inhibition screening due to spectral and inhibitor interferences. To address these limitations of coupled assays, CE has been used to develop enzyme assays for acetyl-coenzyme A carboxylase …

Dna Methylation Patterns Of Interferon Gamma Gene Promoter And Serum Level In Pulmonary Tuberculosis: Their Role In Prognosis, Fawzi Hassan Zayr, Maysaa A. R. Dhahi, Omar F. Abdul-Rasheed, Hashim M. Hashim

Baghdad Science Journal

Tuberculosis (TB) still remains an important medical problem due to high levels of morbidity and mortality worldwide. A series of innate immune mechanisms that create a cytokine network control the pathogenesis of tuberculosis and this response has the capacity to modify the host genomic DNA structure through epigenetic mechanisms such as DNA methylation which could constantly alter the local gene expression pattern that can modulate the metabolism of the tissues and the immune-response. Interferon-gamma (IFN-γ) is an important pro-inflammatory cytokine regulator of the innate immune response to TB. This study aims to determine DNA methylation patterns of INF-γ gene promoter …

Primary Prevention Of Cardiovascular Diseases In Uzbekistan, E. R. Urazaliyeva, A. K. Ermatova, D. Y. Ramanova

Central Asian Problems of Modern Science and Education

Every year, an estimated 17 million people globally die of cardiovascular diseases (CVD), particularly heart attacks and strokes. CVDs occur almost equally in men and women. Although heart attacks and strokes are major killers in all parts of the world, 80% of premature deaths from these causes could be avoided by controlling the main risk factors: tobacco, unhealthy diet and physical inactivity. By 2015, the total number of cardiovascular disease (CVD) deaths (mainly coronary heart disease, stroke, and rheumatic heart disease) had increased globally to 17.5 million from 14.4 million in 1990.

Tlr10 Senses Hiv-1 Proteins And Significantly Enhances Hiv-1 Infection, Bethany M. Henrick, Xiao-Dan Yao, Muhammad Atif Zahoor, Alash’Le Abimiku, Sophia Osawe, Kenneth L. Rosenthal

Department of Food Science and Technology: Faculty Publications

Toll-like receptors (TLRs) play a crucial role in innate immunity and provide a first line of host defense against invading pathogens. Of the identified human TLRs, TLR10 remains an orphan receptor whose ligands and functions are poorly understood. In the present study, we sought to evaluate the level of TLR10 expression in breastmilk (BM) and explore its potential function in the context of HIV-1 infection. We evaluated HIV-1-infected (Nigerian: n = 40) and uninfected (Nigerian: n = 27; Canadian: n = 15) BM samples for TLR expression (i.e., TLR10, TLR2, and TLR1) and report here that HIV-1-infected BM from Nigerian …

Hematological Profile And Gametocyte Carriage In Malaria Patients From Southern Pakistan, Najia Karim Ghanchi, Mohammad Hassaan Khan, Muhammad Abdullah Arain, Mustafa Bin Ali Zubairi, Ahmed Raheem Buksh, Muhammad A. Khan, Mohammad A. Beg

Department of Pathology and Laboratory Medicine

Background: Malarial infection is a major cause of concern, both worldwide and in Pakistan. Gametocytes are the sexual forms of the parasite that are essential for transmission. They fuse inside the mosquito to develop sporozoites. Gametocytes of the plasmodium parasites, which cause the infection, differentiate into male and female gametocytes. These gametocytes constitute the sexual stage of the malaria parasite and are essential in transmission of the disease from human to vector Anopheles. Gametocytes are affected by factors such as host immunity, drug treatment, reticulocytemia, anemia, low levels of asexual parasitemia and stress to the parasite. The aim of this …
