Investigation Of Structure-Activity Relationships Of Antimalarial Drugs Through Novel Plasmodium Falciparum Chloroquine Resistance Resistance Transporter (Pfcrt), Bianca Sanchez Mora, Samuel Lemus, Danielle Nicole Flordeliza, Jillian Nunes, Alexis Valdovinos 2015 Dominican University of California

Investigation Of Structure-Activity Relationships Of Antimalarial Drugs Through Novel Plasmodium Falciparum Chloroquine Resistance Resistance Transporter (Pfcrt), Bianca Sanchez Mora, Samuel Lemus, Danielle Nicole Flordeliza, Jillian Nunes, Alexis Valdovinos

Scholarly and Creative Works Conference

Mutation in the P. falciparum resistance chloroquine transporter (PfCRT) protein causes chloroquine resistance and alters susceptibility to various antimalarial drugs. Mutant PfCRT transports chloroquine out of the parasite digestive vacuole; however, the molecular details of drug-receptor interaction are poorly understood. The antiviral drug amantadine has moderate potency against P. falciparum and acts to reduce the level of chloroquine resistance determined by the pfcrt haplotype. In accordance, chloroquine-resistant parasites show enhanced sensitivity to amantadine. We used continuous, step-wise amantadine selection on three chloroquine-resistant lines of the P. falciparum 106/1 strain. Each of these lines contains a unique pfcrt allele differing ...

Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown 2015 Department of Biological Sciences, University of Tulsa

Ectoparasitism Shortens The Breeding Season In A Colonial Bird, Charles R. Brown, Mary Bomberger Brown

Papers in Natural Resources

When blood-feeding parasites increase seasonally, their deleterious effects may prevent some host species, especially those living in large groups where parasites are numerous, from reproducing later in the summer. Yet the role of parasites in regulating the length of a host’s breeding season—and thus the host’s opportunity for multiple brooding—has not been systematically investigated. The highly colonial cliff swallow (Petrochelidon pyrrhonota), a temperate-latitude migratory songbird in the western Great Plains, USA, typically has a relatively short (eight to nine week) breeding season, with birds rarely nesting late in the summer. Colonies at which ectoparasitic swallow bugs ...

Prehistoric Earth Oven Facilities And The Pathoecology Of Chagas Disease In The Lower Pecos Canyonlands, Karl Reinhard, Adauto Araujo 2015 University of Nebraska-Lincoln

Prehistoric Earth Oven Facilities And The Pathoecology Of Chagas Disease In The Lower Pecos Canyonlands, Karl Reinhard, Adauto Araujo

Papers in Natural Resources

Understanding the endemic region of a disease is part of developing a concept of the disease’s natural history and its threat to human health in both ancient and modern times. Chagas disease is caused by the parasite Trypanosoma cruzi and has recently been identified as an emergent disease in North America. Ancient endemicity and reemergence has been demonstrated by an examination of a mummy found on the border between Coahuila, Mexico and Texas, USA. This mummified man, who died over 1000 years ago, exhibits the gross pathology of megacolon, which is consistent with Chagas disease. We are now exploring ...


Parasitology In An Archaeological Context: Analysis Of Medieval Burials In Nivelles, Belgium, S. E. Rácz, Elisa Pucu de Araujo, E. Jensen, C. Mostek, Johnica J. Morrow, M. L. van Hove, R. Bianucci, D. Willems, F. Heller, Adauto Araujo, Karl Reinhard 2015 University of Nebraska – Lincoln

Karl Reinhard Papers/Publications

Coprolites were recovered from three burials near the Grand Place of Nivelles, Belgium. These remains yielded evidence of geohelminth parasitism. The evidence contributes to studies of differential parasite egg preservation related to the taphonomic conditions within the three burials. Using coprolite analysis techniques, parasite egg concentrations were quantified for each burial. Coprolites from the individual in Burial 122 were abnormally large and abundant, indicating an intestinal blockage. Additionally, this individual hosted an extremely high number of parasites evinced by the calculated parasite egg concentrations (Trichuris trichiura = 1,577,679 total eggs; Ascaris lumbricoides = 202,350 total eggs). Statistical analyses revealed ...


Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, Prageeth Wijemanne, Jun Xing, Emil M. Berberov, David H. Francis, Rodney A. Moxley 2015 University of Nebraska-Lincoln

Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, Prageeth Wijemanne, Jun Xing, Emil M. Berberov, David H. Francis, Rodney A. Moxley

Papers in Veterinary and Biomedical Science

Heat-labile enterotoxin (LT) is an important virulence factor secreted by some strains of enterotoxigenic Escherichia coli (ETEC). The prototypic human-origin strain H10407 secretes LT via a type II secretion system(T2SS). We sought to determine the relationship between the capacity to secrete LT and virulence in porcine-origin wild type (WT) ETEC strains. Sixteen WT ETEC strains isolated from cases of severe diarrheal disease were analyzed by GM1ganglioside enzyme- linked immunosorbent assay tomeasure LT concentrations in culture supernatants. All strains had detectable LT in supernatants by 2 h of culture and 1 strain, which was particularly virulent in gnotobiotic piglets (3030-2 ...

Response To David S. Lindsay Regarding “Self-Archiving Of Publications From The Journal Of Parasitology”, Sue Ann Gardner

Faculty Publications, UNL Libraries

Response to ASP President, David S. Lindsay, regarding his editorial in volume 36, numbers 3-4, of the ASP Newsletter, titled “Self-archiving of publications from the Journal of Parasitology.” Concludes that the Society's contract with Allen Press will expire at some point and, in the interim, there is an opportunity renegotiate with them thoughtfully, or to look for a better outlet for the time-honored Journal of Parasitology. There are many publishing ventures arising from universities themselves, in libraries and academic departments, on viable and stable electronic platforms, that require very little overhead to administer. If even a fraction of the ...

Glutaredoxin 2 (Grx2) Gene Deletion Induces Early Onset Of Age-Dependent Cataracts In Mice, Hongli Wu, Yibo Yu, Larry David, Ye-Shih Ho, Marjorie F. Lou 2014 University of North Texas Health Science Center

Glutaredoxin 2 (Grx2) Gene Deletion Induces Early Onset Of Age-Dependent Cataracts In Mice, Hongli Wu, Yibo Yu, Larry David, Ye-Shih Ho, Marjorie F. Lou

Papers in Veterinary and Biomedical Science

Glutaredoxin 2 (Grx2) is an isozyme of glutaredoxin1 (thioltransferase) present in the mitochondria and nucleus with disulfide reductase and peroxidase activities, and it controls thiol/ disulfide balance in cells. In this study, we investigated whether Grx2 gene deletion could induce faster age-related cataract formation and elucidated the biochemical changes effected by Grx2 gene deletion that may contribute to lens opacity. Slit lamp was used to examine the lenses in Grx2 knock-out (KO) mice and age-matched wild-type (WT) mice ages 1 to 16 months. In the Grx2 null mice, the lens nuclear opacity began at 5 months, 3 months sooner than ...


Coincident Pre-Diabetes Is Associated With Dysregulated Cytokine Responses In Pulmonary Tuberculosis, Nathella Pavan Kumar, Vaithilingam V. Banurekha, Dina Nair, Rathinam Sridhar, Hardy Kornfeld, Thomas B. Nutman, Subash Babu 2014 National Institutes of Health

Coincident Pre-Diabetes Is Associated With Dysregulated Cytokine Responses In Pulmonary Tuberculosis, Nathella Pavan Kumar, Vaithilingam V. Banurekha, Dina Nair, Rathinam Sridhar, Hardy Kornfeld, Thomas B. Nutman, Subash Babu

Open Access Articles

BACKGROUND: Cytokines play an important role in the pathogenesis of pulmonary tuberculosis (PTB)--Type 2 diabetes mellitus co-morbidity. However, the cytokine interactions that characterize PTB coincident with pre-diabetes (PDM) are not known.

METHODS: To identify the influence of coincident PDM on cytokine levels in PTB, we examined circulating levels of a panel of cytokines in the plasma of individuals with TB-PDM and compared them with those without PDM (TB-NDM).

RESULTS: TB-PDM is characterized by elevated circulating levels of Type 1 (IFNgamma, TNFalpha and IL-2), Type 17 (IL-17A and IL-17F) and other pro-inflammatory (IL-1beta, IFNbeta and GM-CSF) cytokines. TB-PDM is also ...

Autoantibodies To The Ny-Eso-1 Tumor Antigen In Metastatic Melanoma: Sialylation Of The Fc Region Of Immunoglobulin G Induces Differential Expression Signatures Of Inflammatory Molecules During Dendritic Cell Differentiation And Maturation, Martin Oaks, Nathaniel Rein, John O. Richards, James Shaffer

Journal of Patient-Centered Research and Reviews

Purpose: We tested the hypothesis that different glycoforms of antibodies from patients with metastatic melanoma have different functional effects on human dendritic cell differentiation and maturation.

Methods: Antibodies to the cancer antigen NY-ESO-1 were affinity-purified from patients with melanoma and further fractionated into different glycoforms by lectin chromatography. Sialic acid-rich and sialic acid-poor fractions of these immunoglobulin G antibodies (IgG) were added to dendritic cell cultures during both differentiation and maturation, and the resulting cellular messenger RNA (mRNA) and culture supernatants were tested by microarray and enzyme-linked immunoassay for molecules related to inflammatory pathways.

Results: We identified unique mRNA and ...

Discovery Of A 240 Million Year Old Nematode Parasite Egg In A Cynodont Coprolite Sheds Light On The Early Origin Of Pinworms In Vertebrates, Jean-Pierre Hugot, Scott Gardner, Victor Borba, Priscilla Araujo, Daniela Leles, Átila Da-Rosa, Juliana Dutra, Luis Fernando Ferreira, Adauto Araújo

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Background: We report the discovery of a nematode parasite egg (Nemata: Oxyurida) from a coprolite closely associated with the remains of several species of Cynodontia, dated to 240 million years old. This finding is particularly significant because this is the oldest record of an oxyurid nematode yet discovered, and because the cynodonts are considered a stem-group of the mammals.

Methods: We extracted material from a fully mineralized coprolite by both scraping the surface, and removing fragments from its interior with clean dental instruments used a single time. A single drop of glycerol from a new vial was added as a ...

BACKGROUND: Long-term homologous and temporary heterologous protection from dengue virus (DENV) infection may be mediated by neutralizing antibodies. However, neutralizing antibody titers (NTs) have not been clearly associated with protection from infection.

METHODOLOGY/PRINCIPAL FINDINGS: Data from two geographic cluster studies conducted in Kamphaeng Phet, Thailand were used for this analysis. In the first study (2004-2007), cluster investigations of 100-meter radius were triggered by DENV-infected index cases from a concurrent prospective cohort. Subjects between 6 months and 15 years old were evaluated for DENV infection at days 0 and 15 by DENV PCR and IgM ELISA. In the second study ...

Mycobacterium tuberculosis infection is associated with a spectrum of clinical outcomes, from long-term latent infection to different manifestations of progressive disease. Pro-inflammatory pathways, such as those controlled by IL-1beta, have the contrasting potential both to prevent disease by restricting bacterial replication, and to promote disease by inflicting tissue damage. Thus, the ultimate contribution of individual inflammatory pathways to the outcome of M. tuberculosis infection remains ambiguous. In this study, we identified a naturally-occurring polymorphism in the human IL1B promoter region, which alters the association of the C/EBPbeta and PU.1 transcription factors and controls Mtb-induced IL-1beta production. The high-IL-1beta ...


Exosomes From Hepatitis C Infected Patients Transmit Hcv Infection And Contain Replication Competent Viral Rna In Complex With Ago2-Mir122-Hsp90, Terence N. Bukong, Fatemeh Momen-Heravi, Karen Kodys, Shashi Bala, Gyongyi Szabo 2014 University of Massachusetts Medical School

Exosomes From Hepatitis C Infected Patients Transmit Hcv Infection And Contain Replication Competent Viral Rna In Complex With Ago2-Mir122-Hsp90, Terence N. Bukong, Fatemeh Momen-Heravi, Karen Kodys, Shashi Bala, Gyongyi Szabo

Open Access Articles

Antibodies targeting receptor-mediated entry of HCV into hepatocytes confer limited therapeutic benefits. Evidence suggests that exosomes can transfer genetic materials between cells; however, their role in HCV infection remains obscure. Here, we show that exosomes isolated from sera of chronic HCV infected patients or supernatants of J6/JFH1-HCV-infected Huh7.5 cells contained HCV RNA. These exosomes could mediate viral receptor-independent transmission of HCV to hepatocytes. Negative sense HCV RNA, indicative of replication competent viral RNA, was present in exosomes of all HCV infected treatment non-responders and some treatment-naive individuals. Remarkably, HCV RNA was associated with Ago2, HSP90 and miR-122 in ...
