United States Navy: Publications

In June, 2003, Egypt’s hospital-based electronic disease surveillance system began to record increased cases of acute febrile illness from governorates in the Nile Delta. In response to a request for assistance from the Egyptian Ministry of Health and the World Health Organization (WHO), the U.S. Naval Medical Research Unit No. 3 (NAMRU-3) provided assistance in identifying the cause and extent of this outbreak. Testing of human clinical samples (n = 375) from nine governorates in Egypt identified 29 cases of RVF viremia that spanned the period of June to October, and a particular focus of disease in Kafr el …

Effects Of Combat Deployment On Risky And Self-Destructive Behavior Among Active Duty Military Personnel, Cynthia J. Thomsen, Valerie A. Stander, Stephanie K. Mcwhorter, Mandy M. Rabenhorst, Joel S. Milner

United States Navy: Publications

Although research has documented negative effects of combat deployment on mental health, few studies have examined whether deployment increases risky or self-destructive behavior. The present study addressed this issue. In addition, we examined whether deployment effects on risky behavior varied depending on history of pre-deployment risky behavior, and assessed whether psychiatric conditions mediated effects of deployment on risky behavior. In an anonymous survey, active duty members of the U.S. Marine Corps and U.S. Navy (N = 2116) described their deployment experiences and their participation in risky recreational activities, unprotected sex, illegal drug use, self-injurious behavior, and suicide attempts during …

While they can be deadly, they provide important tools for developing treatments and building nanotechnology. So the challenge for World of Viruses is to engage the public with the ubiquitous yet mysterious virus, taking them from confusion and misconception to …

Banf1 Is Required To Maintain The Self-Renewal Of Both Mouse And Human Embryonic Stem Cells, Jesse L. Cox, Sunil K. Mallanna, Briana D. Ormsbee, Michelle Desler, Matthew S. Wiebe, Angie Rizzino

Nebraska Center for Virology: Faculty Publications

Self-renewal is a complex biological process necessary for maintaining the pluripotency of embryonic stem cells (ESCs). Recent studies have used global proteomic techniques to identify proteins that associate with the master regulators Oct4, Nanog, and Sox2 in ESCs or in ESCs during the early stages of differentiation. Through an unbiased proteomic screen, Banf1 was identified as a Sox2- associated protein. Banf1 has been shown to be essential for worm and fly development but, until now, its role in mammalian development and ESCs has not been explored. In this study, we examined the effect of knocking down Banf1 on ESCs. We …

Despite the histological similarity of ependymomas from throughout the neuroaxis, the disease likely comprises multiple independent entities, each with a distinct molecular pathogenesis. Transcriptional profiling of two large independent cohorts of ependymoma reveals the existence of two demographically, transcriptionally, genetically, and clinically distinct groups of posterior fossa (PF) ependymomas. Group A patients are younger, have laterally located tumors with a balanced genome, and are much more likely to exhibit recurrence, metastasis at recurrence, and death compared with Group B patients. Identification and optimization of immunohistochemical (IHC) markers for PF ependymoma subgroups allowed validation of our findings on a third independent …

Epithelial To Mesenchymal Transition (Emt) Induced By Bleomycin Or TfgB1/Egf In Murine Induced Pluripotent Stem Cell-Derived Alveolar Type Ii-Like Cells, Zaida A. Alipio, Nathan Jones, Wenbin Liao, Jianchang Yang, Shilpa Kulkarni, K. Sree Kumar, Martin Hauer-Jensen, David C. Ward, Yupo Ma, Louis M. Fink

Uniformed Services University of the Health Sciences

Induced pluripotent stem (iPS) cells are derived from reprogrammed somatic cells and are similar to embryonic stem (ES) cells in morphology, gene/protein expression, and pluripotency. In this study, we explored the potential of iPS cells to differentiate into alveolar Type II (ATII)-like epithelial cells. Analysis using quantitative real time polymerase chain reaction and immunofluorescence staining showed that pulmonary surfactant proteins commonly expressed by ATII cells such as surfactant protein A (SPA), surfactant protein B (SPB), and surfactant protein C (SPC) were unpregulated in the differentiated cells. Microphilopodia characteristics and lamellar bodies were observed by transmission electron microscopy and lipid deposits …

Uniformed Services University of the Health Sciences

Background: Bipolar disorder (BD) is a common mental disorder, subdivided into BD-I and BD-II. Currently, few biomarkers differentiate BD-I from BD-II. However, it is suggested that peripheral blood mononuclear cell (PBMC) mRNA levels of p11 and positron emission tomography (PET) might be potential biomarkers for BD.

Methods: Healthy controls (HCs), BD-I, and BD-II patients in remission (n = 20 in each group) underwent a resting PET study with the radiotracer [¹⁸F]-2-deoxy-2-fluoro-_D-glucose (¹⁸F-FDG). PBMC p11 mRNA levels were determined by quantitative real-time PCR.

Results: Comparing BD patients to HCs, normalized glucose metabolism (NGM) was higher …

Protein Kinase C Mediates Peroxynitrite Toxicity To Oligodendrocytes, Shihe Li, Wen Lin, Flaubert Tchantchou, Ruby Lai, Jie Wen, Yumin Zhang

Uniformed Services University of the Health Sciences

Peroxynitrite has been suggested to be the potent oxidant causing toxicity to neurons and oligodendrocytes (OLs). Our previous studies have illustrated that intracellular zinc liberation contributes to peroxynitrite toxicity to mature OLs. In this study, we further investigated the signaling pathways involved in this event and identified protein kinase C (PKC) as an important early signaling molecule. We found that a non-selective PKC inhibitor bisindolylmaleimide-1 blocked OL toxicity induced by a peroxynitrite generator SIN-1 and exogenous zinc. The protective effects were due to its inhibition on ERK1/2 phosphorylation and ROS generation. The same phenomenon was also observed in OLs following …

Anxiety Phenotype In Mice That Overexpress Protein Kinase A, Margaret F. Keil, George Briassoulis, Nirmal Gokarn, Maria Nesterova, T. John Wu, Constantine A. Stratakis

Uniformed Services University of the Health Sciences

The role of cyclic adenosine monophosphate/protein kinase A (cAMP/PKA) signaling in the molecular pathways involved in fear and memory is well established. Prior studies in our lab reported that transgenic mice with an inactivating mutation in Prkar1a gene (codes for the 1-alpha regulatory subunit (R1α) of PKA) exhibited behavioral abnormalities including anxiety and depression. In the present study, we examined the role of altered PKA signaling on anxiety-like behaviors in Prkar1a^+/- mice compared to wild-type (WT) littermates. The elevated plus maze (EPM) and marble bury (MB) tests were used to assess anxiety-like behavior. The hotplate test was performed to …

Nicotine Induced Cpg Methylation Of Pax6 Binding Motif In Star Promoter Reduces The Gene Expression And Cortisol Production, Tingting Wang, Man Chen, Lian Liu, Huaiyan Cheng, You-E Yan, Ying-Hong Feng, Hui Wang

Uniformed Services University of the Health Sciences

Steroidogenic acute regulatory protein (StAR) mediates the rate-limiting step in the synthesis of steroid hormones, essential to fetal development. We have reported that the StAR expression in fetal adrenal is inhibited in a rat model of nicotine-induced intrauterine growth retardation (IUGR). Here using primary human fetal adrenal cortex (pHFAC) cells and a human fetal adrenal cell line NCI-H295A, we show that nicotine inhibits StAR expression and cortisol production in a dose- and time-dependent manner, and prolongs the inhibitory effect on cells proliferating over 5 passages after termination of nicotine treatment. Methylation detection within the StAR promoter region uncovers a single …

Schistosoma Comparative Genomics: Integrating Genome Structure, Parasite Biology And Anthelmintic Discovery, Martin T. Swain, Denis M. Larkin, Conor R. Caffrey, Stephen J. Davies, Alex Loukas, Patrick J. Skelly, Karl F. Hoffmann

Uniformed Services University of the Health Sciences

Schistosoma genomes provide a comprehensive resource for identifying the molecular processes that shape parasite evolution and for discovering novel chemotherapeutic or immunoprophylactic targets. Here, we demonstrate how intragenus and intergenus comparative genomics can be used to drive these investigations forward, illustrate the advantages and limitations of these approaches and review how post-genomic technologies offer complementary strategies for genome characterisation. Although sequencing and functional characterisation of other schistosome/platyhelminth genomes continues to expedite anthelmintic discovery, we contend that future priorities should equally focus on improving assembly quality, and chromosomal assignment, of existing schistosome/platyhelminth genomes.

Giant Viruses, James L. Van Etten

James Van Etten Publications

The common view of viruses, mostly true, is of tiny burglars that sneak into cells, grab the biosynthetic controls and compel the cell to make huge numbers of progeny that break out of the cell and keep the replication cycle going. Viruses are supposed to be diminutive even compared to cells that are just a micrometer (1,000 nanometers) in diameter. They are supposed to travel light, making do with just a few well-adapted genes.

In 1992, a new microorganism was isolated from a power-plant cooling tower in Bradford, England, where Timothy Robotham, a microbiologist at Leeds Public Health Laboratory, was …

Reactive oxygen species (ROS) produced in macrophages is critical for microbial killing, but they also take part in inflammation and antigen presentation functions. MicroRNAs (miRNAs) are endogenous regulators of gene expression, and they can control immune responses. To dissect the complex nature of ROS-mediated effects in macrophages, we sought to characterize miRNAs that are responsive to oxidative stress-induced with hydrogen peroxide (H₂O₂) in the mouse macrophage cell line, RAW 264.7. We have identified a set of unique miRNAs that are differentially expressed in response to H₂O₂. These include miR-27a*, miR-27b*, miR-29b*, miR-24-2*, …

Investigations Of Transcript Expression In Fathead Minnow (Pimephales Promelas) Brain Tissue Reveal Toxicological Impacts Of Rdx Exposure, Kurt A. Gust, Mitchell S. Wilbanks, Xin Guan, Mehdi Pirooznia, Tanwir Habib, Leslie Yoo, Henri Wintz, Chris D. Vulpe, Edward J. Perkins

United States Army: Publications

Production, usage and disposal of the munitions constituent (MC) cyclotrimethylenetrinitramine (RDX) has led to environmental releases on  military facilities. The chemical attributes of RDX are conducive for leaching to surface water which may put aquatic organisms at risk of exposure. Because RDX has been observed to cause aberrant neuromuscular effects across a wide range of animal phyla, we assessed the effects of RDX on central nervous system (CNS) functions in the representative aquatic ecotoxicological model species, fathead minnow (Pimephales promelas). We developed a fathead minnow brain-tissue cDNA library enriched for transcripts differentially expressed in response to RDX and …

Antimicrobial Decapeptide Ksl-W Attenuates Candida Albicans Virulence By Modulating Its Effects On Toll-Like Receptor, Human Β-Defensin, And Cytokine Expression By Engineered Human Oral Mucosa, A. Semlali, K. P. Leung, S. Curt, M. Rouabhia

United States Army: Publications

We investigated the toxicity of synthetic antimicrobial decapeptide KSL-W on normal human gingival epithelial cell cultures, its effect on Candida albicans adhesion and growth, and the activation of epithelial cell innate immunity. Our results indicate that KSL-W had no toxic effect on cell adhesion or growth, suggesting its safe use with human cells. Pre-treating C. albicans with KSL-W attenuated the yeast’s virulence as demonstrated by its reduced adhesion and growth on engineered human oral mucosa epithelium and the subsequent decreased expression of some innate defense molecules by targeted epithelial cells. Indeed, the expression of Toll-like receptors and human β-defensins was …
