Understanding The Differences Between Neuronal Calcium Sensor Proteins: A Comparison Of Neurocalcin Delta And Hippocalcin, Jeffrey M. Viviano

Graduate School of Biomedical Sciences Theses and Dissertations

Many neuronal functions, including learning and memory are driven by changes in intracellular Ca2+concentrations. The Neuronal Calcium Sensor (NCS) family of proteins is responsible for mediating the response to calcium. They are typically comprised of 4 EF hands; of which EF 2, 3, and 4 bind calcium.

Hypothesis: NCS proteins carry out unique, non-overlapping functions, and that specific characteristics of the family can be mapped to precise regions of the proteins.

Results: The effect on the following properties were investigated primarily on two highly similar NCS proteins, Neurocalcin Delta (NCALD) and Hippocalcin (HPCA): (1) Response to calcium was determined through …

Silica Uptake And Release In Live And Decaying Biomass In A Northern Hardwood Forest, Wim Clymans, Daniel J. Conley, John J. Battles, Patrick J. Frings, Mary Margaret Koppers, Gene E. Likens, Chris E. Johnson

Civil and Environmental Engineering - All Scholarship

In terrestrial ecosystems, a large portion (20–80%) of the dissolved Si (DSi) in soil solution has passed through vegetation. While the importance of this “terrestrial Si filter” is generally accepted, few data exist on the pools and fluxes of Si in forest vegetation and the rate of release of Si from decomposing plant tissues. We quantified the pools and fluxes of Si through vegetation and coarse woody debris (CWD) in a northern hardwood forest ecosystem (Watershed 6, W6) at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, USA. Previous work suggested that the decomposition of CWD may have significantly …

Identifying Soil Constraints That Limit Wheat Yield In The South-West Of Western Australia, Dennis Van Gool

Resource management technical reports

This is a novel approach using regional-scale information. The analysis estimated that:

• most of the wheat-growing land in south-west WA has one or more soil constraints
• about 1.6 million hectares (9% of the total area) are not suitable for cropping
• about 2.2 million hectares (12% of the total area) are suitable for cropping but are subject to many (more than 3) constraints; soil amelioration is unlikely to significantly improve profitable yield gain
• subsurface acidity extends over 12.6 million hectares (about 70% of the total area); about 7.6 million hectares of that area (42% of the total area) is estimated to …

Can We Predict Ectotherm Responses To Climate Change Using Thermal Performance Curves And Body Temperatures?, Brent J Sinclair, Katie E Marshall, Mary A Sewell, Danielle L Levesque, Christopher S Willett, Stine Slotsbo, Yunwei Dong, Christopher D G Harley, David J Marshall, Brian S Helmuth, Raymond B Huey

Biology Publications

Thermal performance curves (TPCs), which quantify how an ectotherm's body temperature (Tb ) affects its performance or fitness, are often used in an attempt to predict organismal responses to climate change. Here, we examine the key - but often biologically unreasonable - assumptions underlying this approach; for example, that physiology and thermal regimes are invariant over ontogeny, space and time, and also that TPCs are independent of previously experienced Tb. We show how a critical consideration of these assumptions can lead to biologically useful hypotheses and experimental designs. For example, rather than assuming that TPCs are fixed during ontogeny, one …

The Rodent Parvovirus H-1 And Its Potential In Combination With Tien Hsien Liquid As A Treatment For Breast Cancer, Hayley I. Spires

Selected Honors Theses

Breast cancer is responsible for 12% of cancer diagnoses each year, and it is the leading cause of cancer-related mortality in women worldwide. Current treatments have provided some success in combatting the disease but are not considered a final solution. The framework for how researchers approach cancer has continued to change, and this includes the introduction of oncolytic viruses as novel therapeutics for cancer. The rodent parvovirus H-1 has shown strong potential in clinical and subclinical trials, but its S phase dependency limits its usefulness against cancer stem cell populations. Tien Hsien Liquid is commerically available, nontoxic, and has shown …

Predators Catalyze An Increase In Chloroviruses By Foraging On The Symbiotic Hosts Of Zoochlorellae, John Delong, Zeina Al-Ameeli, Garry A. Duncan, James L. Van Etten, David D. Dunigan Ph. D.

James Van Etten Publications

Virus population growth depends on contacts between viruses and their hosts. It is often unclear how sufficient contacts are made between viruses and their specific hosts to generate spikes in viral abundance. Here, we show that copepods, acting as predators, can bring aquatic viruses and their algal hosts into contact. Specifically, predation of the protist Paramecium bursaria by copepods resulted in a >100-fold increase in the number of chloroviruses in 1 d. Copepod predation can be seen as an ecological “catalyst” by increasing contacts between chloroviruses and their hosts, zoochlorellae (endosymbiotic algae that live within paramecia), thereby facilitating viral population …

Identifying Groundwater - Dependent Wetlands Of The Broome Sandstone Aquifer In The La Grange Groundwater Area, Nicholas Wright, Richard J. George Dr, Robert Paul, Paul Raper

Resource management technical reports

This report identifies wetlands that are likely to be dependent on the Broome Sandstone aquifer within the La Grange groundwater allocation area. The Broome Sandstone aquifer is the dominant groundwater resource in the area. With potential agricultural growth of this area, it is necessary to understand, monitor and manage the aquifer and its dependent wetlands. This report describes how we created a watertable surface that was used to identify wetlands and to determine which of the previously mapped wetlands are likely to be sourced from the Broome Sandstone aquifer. A watertable surface was created from 148 points taken from bore …

Six-Year Longitudinal Study Of Fasciola Hepatica Bulk Milk Antibody Elisa In The Dairy Dense Region Of The Republic Ireland, Maria Pia Munita

Department of Biological Sciences Publications

Abstract

Completion of the F. hepatica lifecycle is dependent on suitable climatic conditions for development of immature stages of the parasite, and its snail intermediate host. Few investigations have been conducted regarding temporal variations in F. hepatica status in Irish dairy herds. The current study aimed to conduct a longitudinal study examining annual and seasonal trends in bulk milk seropositivity over six years, while also investigating associations with soil temperature, rainfall and flukicide treatment. Monthly bulk milk samples (BTM) were submitted by 28 herds between March 2009 and December 2014. In all, 1337 samples were analysed using a Cathepsin L1 …

Leukocyte Telomere Length In Relation To 17 Biomarkers Of Cardiovascular Disease Risk: A Cross-Sectional Study Of Us Adults, David Rehkopf, Belinda L. Needham, Jue Lin, Elizabeth Blackburn, Ami R. Zota, Janet Wojcicki, Elissa Epel

Environmental and Occupational Health Faculty Publications

Background

Leukocyte telomere length (LTL) is a putative biological marker of immune system age, and there are demonstrated associations between LTL and cardiovascular disease. This may be due in part to the relationship of LTL with other biomarkers associated with cardiovascular disease risk. However, the strength of associations between LTL and adiposity, metabolic, proinflammatory, and cardiovascular biomarkers has not been systematically evaluated in a United States nationally representative population.

Methods and Findings

We examined associations between LTL and 17 cardiovascular biomarkers, including lipoproteins, blood sugar, circulatory pressure, proinflammatory markers, kidney function, and adiposity measures, in adults ages 20 to 84 …

Chemokine Levels In The Penile Coronal Sulcus Correlate With Hiv-1 Acquisition And Are Reduced By Male Circumcision In Rakai, Uganda., Jessica L Prodger, Ronald H Gray, Brett Shannon, Kamnoosh Shahabi, Xiangrong Kong, Kate Grabowski, Godfrey Kigozi, Fred Nalugoda, David Serwadda, Maria J Wawer, Steven J Reynolds, Cindy M. Liu, Aaron A R Tobian, Rupert Kaul

Environmental and Occupational Health Faculty Publications

Individual susceptibility to HIV is heterogeneous, but the biological mechanisms explaining differences are incompletely understood. We hypothesized that penile inflammation may increase HIV susceptibility in men by recruiting permissive CD4 T cells, and that male circumcision may decrease HIV susceptibility in part by reducing genital inflammation. We used multi-array technology to measure levels of seven cytokines in coronal sulcus (penile) swabs collected longitudinally from initially uncircumcised men enrolled in a randomized trial of circumcision in Rakai, Uganda. Coronal sulcus cytokine levels were compared between men who acquired HIV and controls who remained seronegative. Cytokines were also compared within men before …

Department of Biological & Biomedical Sciences

High prevalence of premature coronary heart disease in Pakistanis compared to other populations points towards the genetic predisposition of this population to develop this disease. Since no investigations have been carried out in Pakistan to study the relationship of polymorphisms in genes involved in homocysteine cycle, the objective of the present study was to find out if there is any association of methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C; methionine synthase (MS) A2756G; cystathionine-beta-synthase (CBS) 844ins68, G919A polymorphisms with premature acute myocardial infarction (AMI) in a population of Pakistani patients with this disease. In a cross-sectional study, DNA samples of 143 AMI …

Genetic Diversity, Pathogens And Parasites Of Feral Honey Bees In Swarms From Eight Mississippi Counties, A. L. Szalanskl, C. E. Trammel, D. Cleary, A. D. Tripodi

Midsouth Entomologist

A study was conducted on the genetic diversity of honey bees, Apis mellifera L., from feral colonies and swarms collected from Mississippi by sequencing a portion of the mitochondrial DNA COI – COII region. From the 38 samples analyzed, we observed 11 haplotypes collected from eight counties. These haplotypes represented three of the four A. mellifera lineages known to have been imported into the United States (C, M and O). Of the seven C lineage haplotypes, three were not found in previous queen breeder studies in the United States. The O lineage, with two haplotypes observed, accounted for 18% of …

Human-Associated Bacteroides Spp. And Human Polyomaviruses As Microbial Source Tracking Markers In Hawaii, Marek Kirs, Roberto A Caffaro-Filho, Mayee Wong, Valerie J. Harwood, Philip Moravcik, Roger S Fujioka

Integrative Biology Faculty and Staff Publications

Identification of sources of fecal contaminants is needed to (i) determine the health risk associated with recreational water use and (ii) implement appropriate management practices to mitigate this risk and protect the environment. This study evaluated human-associated Bacteroides spp. (HF183TaqMan) and human polyomavirus (HPyV) markers for host sensitivity and specificity using human and animal fecal samples collected in Hawaii. The decay rates of those markers and indicator bacteria were identified in marine and freshwater microcosms exposed and not exposed to sunlight, followed by field testing of the usability of the molecular markers. Both markers were strongly associated with sewage, although …

Reproductive Success Through High Pollinator Visitation Rates Despite Self Incompatibility In An Endangered Wallflower, Miranda K. Melen, Julie A. Herman, Jessica Lucas, Rachel E. O’Malley, Ingrid M. Parker, Aaron M. Thom, Justen B. Whittall

Biology

PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is pollinator visitation sufficient to ensure reproductive success? Is there evidence of inbreeding/outbreeding depression? We characterized the mating system, primary pollinators, pollen limitation, and inbreeding/outbreeding depression in Erysimum teretifolium to guide conservation efforts.

METHODS: We compared seed production following self pollination and within- and between-population crosses. Pollen tubes were visualized after self pollinations and between-population pollinations. Pollen limitation was tested in the field. Pollinator …

Detritus Quality And Locality Determines Survival And Mass, But Not Export, Of Wood Frogs At Metamorphosis, Joseph R. Milanovich, Kyle Barrett, John A. Crawford

Faculty Scholarship

Single-site experiments have demonstrated detritus quality in wetlands can have strongly negative, neutral, and even positive influences on wildlife. However, an examination of the influence of detritus quality across several regions is lacking and can provide information on whether impacts from variation in detritus quality are consistent across species with wide ranges. To address this gap in regional studies we examined effects of emergent and allochthonous detritus of different nutrient qualities on amphibians and assessed a mechanism that may contribute to potential impacts. We used aquatic mesocosms to raise wood frogs (Rana sylvatica) from two regions of the United States …

Methods To Assess The Direct Interaction Of C. Jejuni With Mucins, Julie Ann Naughton, Marguerite Clyne, Gina Duggan, Billy Bourke

Books/Book chapters

Studies of the interaction of bacteria with mucus secreting cells can be complemented at a more mechanistic level by exploring the interaction of bacteria with purified mucins. Here we describe a far western blotting approach to show how C. jejuni proteins separated by SDS PAGE and transferred to a membrane or slot blotted directly onto a membrane can be probed biotinylated mucin. In addition we describe the use of novel mucin microarrays to assess bacterial interactions with mucins in a high throughput manner.
