Therapeutic Efficacy Of Cerium Oxide Nanoparticles Against Sepsis Induced Multi-Organ Dysfunction Syndrome In Sprague Dawley Rats, Nandini Durga Prasanna Kumar Manne Jan 2014

Therapeutic Efficacy Of Cerium Oxide Nanoparticles Against Sepsis Induced Multi-Organ Dysfunction Syndrome In Sprague Dawley Rats, Nandini Durga Prasanna Kumar Manne

Theses, Dissertations and Capstones

Sepsis is a generalized term that signifies the presence of a pathogen in the blood stream to which the body responds by eliciting a systemic inflammatory response. Although sepsis is the leading cause of death in non-coronary intensive care units in United States, there are currently no FDA approved therapeutic drugs to treat this disorder. Cerium oxide nanoparticles (CeO2) have been shown to exhibit anti-oxidant, anti-inflammatory, and anti-bacterial properties both in vitro and in vivo. Whether CeO2 nanoparticles can be used for the treatment of sepsis is currently unclear.

To investigate whether CeO2 nanoparticles can …

The implementation of new antiretroviral therapies targeting transcription of early viral proteins in postintegrated HIV-1 can aid in overcoming current therapy limitations. Using high-throughput screening assays, we have previously described a novel Tat-dependent HIV-1 transcriptional inhibitor named 6-bromoindirubin-3′-oxime (6BIO). The screening of 6BIO derivatives yielded unique compounds that show potent inhibition of HIV-1 transcription. We have identified a second-generation derivative called 18BIOder as an inhibitor of HIV-1 Tat-dependent transcription in TZM-bl cells and a potent inhibitor of GSK-3β kinase in vitro. Structurally, 18BIOder is half the molecular weight and structure of its parental compound, 6BIO. More importantly, we also …

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Opisthorchiasis and Opisthorchis viverrini-associated bile duct cancer represent major public health threats in Thailand and Laos. The tegument of this food borne fluke plays pivotal roles in parasite metabolism, homeostasis and osmoregulation. Excretory/secretory products also pass from the fluke to the biliary environment, products that likely underlie pathogenesis of liver fluke infection. Aquaporins (AQPs), belong to the major intrinsic protein superfamily of integral plasma membrane channel proteins that selectively transport water across cell membranes. AQPs play key roles as water and ion transport channels through the tegument of helminth parasites.

Methods

Here, two forms of AQP mRNAs from the …

Biomphalaria glabrata snails play an integral role in the transmission of Schistosoma mansoni, the causative agent for human schistosomiasis in the Western hemisphere. For the past two decades, tremendous advances have been made in research aimed at elucidating the molecular basis of the snail/parasite interaction. The growing concern that there is no vaccine to prevent schistosomiasis and only one effective drug in existence provides the impetus to develop new control strategies based on eliminating schistosomes at the snail-stage of the life cycle. To elucidate why a given snail is not always compatible to each and every schistosome it encounters, B. …

Circulating microRNAs (c-miRNAs) have be identified in saliva, urine and blood, which has led to increasing interest in their development as biomarkers for diverse diseases including cancers. One of the key advantages of c-miRNAs over other biomarkers is the ability to be amplified and quantified by quantitative PCR (qPCR). However, at phlebotomy when whole blood is dispensed into heparinized tubes, residual levels of the anti-coagulant lithium heparin may remain in the plasma and hence with RNA isolated from the plasma. This can confound the detection of c-miRNAs by qPCR because it inhibits reverse transcriptase (RT). Here we present a procedure, …

Infection with helminth parasites remains a persistent public health problem in developing countries. Three of these pathogens, the liver flukes Clonorchis sinensis, Opisthorchis viverrini and the blood fluke Schistosoma haematobium, are of particular concern due to their classification as Group 1 carcinogens: infection with these worms is carcinogenic. Using liquid chromatography-mass spectrometry (LC-MS/MS) approaches, we identified steroid hormone like (e.g., oxysterol-like, catechol estrogen quinone-like, etc.) metabolites and related DNA-adducts, apparently of parasite origin, in developmental stages including eggs of S. haematobium, in urine of people with urogenital schistosomiasis, and in the adult stage of O. viverrini. Since these kinds of …

In 2007, the National Institutes of Health (NIH) launched the Human Microbiome Project (HMP), a $150 million initiative to characterize the microbial communities found at several different sites on the human body and to analyze the role of these microbes in human health and disease. Many lines of research have demonstrated the significant role of the microbiota in human physiology. The microbiota is involved, for example, in the healthy development of the immune system, prevention of infection from pathogenic or opportunistic microbes, and maintenance of intestinal barrier function. The HMP findings are helping us understand the role and variation of …

Journal Articles

Background: The incidence, recurrence, and all-cause mortality rate for Clostridium difficile-associated diarrhea (CDAD) has increased markedly over the past 10 years despite treatment. Low vitamin D levels are known to impair immune responses to infection and are associated with increased mortality. We compared the role of patient comorbidity measured by the Charlson Comorbidity Index (CCI) with vitamin D levels to ascertain whether vitamin D levels were an independent variable affecting the outcome of CDAD or a marker of overall comorbidity. Methods: A prospective cohort study studied 62 patients hospitalized between 2008 and 2009 with manifestations of CDAD and a positive …

Enhanced endogenous interferon (IFN) stimulated gene (ISG) signature has been associated with nonresponsiveness to hepatitis C treatment using pegylated-IFNα (pegIFNα) and ribavirin (RBV) in human immunodeficiency virus/hepatitis C virus (HIV/HCV) coinfected patients. Using a proteomic approach, we identified high levels of IFNα receptor 2a (IFNαR2a) in the serum of null responders to pegIFNα/RBV. IFNαR2a inhibited antiviral activity of all formulations of IFNα in JFH/Huh7.5 cells. Furthermore, serum from null responders, but not from those who achieved sustained virologic response, suppressed IFN-signaling and ISG expression in IFNα-stimulated PBMCs of healthy donors in an IFNαR2a specific fashion. An IFNαR2a transgenic mice model …


Integrating Phage Therapy Into Western Medicine, Jacob B. Jaminet Jan 2014

Integrating Phage Therapy Into Western Medicine, Jacob B. Jaminet

UROP Posters

The World Health Organization has described the rise of antibiotic use as a “global heath security emergency” (who.int). With the growing concern about antibiotic resistant bacteria, there has been an increased interest in bacteriophages. Bacteriophages are high-specific viruses that only infect bacteria. The use of bacteriophages medicinally to treat bacteria is called phage therapy. Research in phage therapy gained momentum until the introduction of antibiotics. While the USA and other Western countries accepted antibiotics, the Soviet Union and their satellite nations still continued to research phages. Since the funding for research was supplied by the Soviet military, the results of …

Global Analysis Of Chlorella Variabilis Nc64a Mrna Profiles During The Early Phase Of Paramecium Bursaria Chlorella Virus-1 Infection, Janet M. Rowe, Adrien Jeanniard, James R. Gurnon, Yuannan Xia, David D. Dunigan, James L. Van Etten, Guillaume Blanc

Nebraska Center for Virology: Faculty Publications

The PBCV-1/Chlorella variabilis NC64A system is a model for studies on interactions between viruses and algae. Here we present the first global analyses of algal host transcripts during the early stages of infection, prior to virus replication. During the course of the experiment stretching over 1 hour, about a third of the host genes displayed significant changes in normalized mRNA abundance that either increased or decreased compared to uninfected levels. The population of genes with significant transcriptional changes gradually increased until stabilizing at 40 minutes post infection. Functional categories including cytoplasmic ribosomal proteins, jasmonic acid biosynthesis and anaphase promoting …


Dynamic Attachment Of Chlorovirus Pbcv-1 To Chlorella Variabilis, Irina Agarkova, Brigitte Hertel, Xinzheng Zhang, Les Lane, Alexander Tchourbanov, David D. Dunigan, Gerhard Thiel, Michael G. Rossmann, James L. Van Etten Jan 2014

Dynamic Attachment Of Chlorovirus Pbcv-1 To Chlorella Variabilis, Irina Agarkova, Brigitte Hertel, Xinzheng Zhang, Les Lane, Alexander Tchourbanov, David D. Dunigan, Gerhard Thiel, Michael G. Rossmann, James L. Van Etten

Nebraska Center for Virology: Faculty Publications

Chloroviruses infect their hosts by specifically binding to and degrading the cell wall of their algal hosts at the site of attachment, using an intrinsic digesting enzyme(s). Chlorovirus PBCV-1 stored as a lysate survived longer than virus alone, suggesting virus attachment to cellular debris may be reversible. Ghost cells (algal cells extracted with methanol) were used as a model to study reversibility of PBCV-1 attachment because ghost cells are as susceptible to attachment and wall digestion as are live cells. Reversibility of attachment to ghost cells was examined by releasing attached virions with a cell wall degrading enzyme extract. The …

Genetic Variation And Possible Mechanisms Driving The Evolution Of Worldwide Fig Mosaic Virus Isolates, Jeewan Jyot Walia, Anouk Willemsen, Eminur Elci, Kadriye Caglayan, Bryce W. Falk, Luis Rubio

Nebraska Center for Virology: Faculty Publications

Fig mosaic virus (FMV) is a multipartite negative-sense RNA virus infecting fig trees worldwide. FMV is transmitted by vegetative propagation and grafting of plant materials, and by the eriophyid mite Aceria ficus. In this work, the genetic variation and evolutionary mechanisms shaping FMV populations were characterized. Nucleotide sequences from four genomic regions (each within the genomic RNAs 1, 2, 3, and 4) from FMV isolates from different countries were determined and analyzed. FMV genetic variation was low, as is seen for many other plant viruses. Phylogenetic analysis showed some geographically distant FMV isolates which clustered together, suggesting long-distance migration. …

Turnip Crinkle Virus Coat Protein Inhibits The Basal Immune Response To Virus Invasion In Arabidopsis By Binding To The Nac Transcription Factor Tip, Teresa Donze, Feng Qu, Paul Twigg, T. Jack Morris Jan 2014

Turnip Crinkle Virus Coat Protein Inhibits The Basal Immune Response To Virus Invasion In Arabidopsis By Binding To The Nac Transcription Factor Tip, Teresa Donze, Feng Qu, Paul Twigg, T. Jack Morris

Nebraska Center for Virology: Faculty Publications

Turnip crinkle virus (TCV) has been shown to interact with a NAC transcription factor, TIP, of Arabidopsis thaliana, via its coat protein (CP). This interaction correlates with the resistance response manifested in TCV-resistant Arabidopsis ecotype Di-17. We report that failure of a mutated CP to interact with TIP triggered the corresponding TCV mutant (R6A) to cause more severe symptoms in the TCV-susceptible ecotype Col-0. We hypothesized that TCV regulates antiviral basal immunity through TIP-CP interaction. Consistent with this hypothesis, we found that the rate of accumulation of R6A was measurably slower than wild-type TCV over the course of an …


Light Stimulates The Mouse Adrenal Through A Retinohypothalamic Pathway Independent Of An Effect On The Clock In The Suprachiasmatic Nucleus, Silke Kiessling, Patricia J. Sollars, Gary E. Pickard Jan 2014

Light Stimulates The Mouse Adrenal Through A Retinohypothalamic Pathway Independent Of An Effect On The Clock In The Suprachiasmatic Nucleus, Silke Kiessling, Patricia J. Sollars, Gary E. Pickard

School of Veterinary and Biomedical Sciences: Faculty Publications

The brain’s master circadian pacemaker resides within the hypothalamic suprachiasmatic nucleus (SCN). SCN clock neurons are entrained to the day/night cycle via the retinohypothalamic tract and the SCN provides temporal information to the central nervous system and to peripheral organs that function as secondary oscillators. The SCN clock-cell network is thought to be the hypothalamic link between the retina and descending autonomic circuits to peripheral organs such as the adrenal gland, thereby entraining those organs to the day/night cycle. However, there are at least three different routes or mechanisms by which retinal signals transmitted to the hypothalamus may be conveyed …

The Role Of Scavenger Receptor Class B Type I-Regulated Inducible Glucocorticoids In Sepsis, Junting Ai Jan 2014

The Role Of Scavenger Receptor Class B Type I-Regulated Inducible Glucocorticoids In Sepsis, Junting Ai

Theses and Dissertations--Nutritional Sciences

Sepsis claims over 215,000 lives in the US annually. Inducible glucocorticoids (iGC) is produced during sepsis. However, the precise effects of iGC in sepsis remain unclear due to a lack of appropriate animal models. Glucocorticoid (GC) insufficiency is associated with a marked increase in mortality and occurs in 60% of severe septic patients. Yet the conclusion of GC therapy on septic patients is still controversial.


Scavenger receptor class B type I (SR-BI) in the adrenal mediates the selective uptake of cholesteryl ester from lipoproteins for GC synthesis. SR-BI-/- mice completely lack iGC during sepsis and are highly susceptible to septic …
