Meta-Analysis Reveals Complex Marine Biological Responses To The Interactive Effects Of Ocean Acidification And Warming, Ben P. Harvey, Dylan Gwynn-Jones, Philippa J. Moore

Research outputs 2013

Ocean acidification and warming are considered two of the greatest threats to marine biodiversity, yet the combined effect of these stressors on marine organisms remains largely unclear. Using a meta-analytical approach, we assessed the biological responses of marine organisms to the effects of ocean acidification and warming in isolation and combination. As expected biological responses varied across taxonomic groups, life-history stages, and trophic levels, but importantly, combining stressors generally exhibited a stronger biological (either positive or negative) effect. Using a subset of orthogonal studies, we show that four of five of the biological responses measured (calcification, photosynthesis, reproduction, and survival, …

Methods. Seventeen women aged 61 ± 9 years with mild to severe BCRL participated in this study. Participants completed a high load (6-8 repetition maximum) and low load …

A Necrotic Stimulus Is Required To Maximize Matrix-Mediated Myogenesis In Mice, Drew Kuraitis, Maria Grazia Berardinelli, Erik J. Suuronen, Antonio Musaro

Research outputs 2013

Biomaterials that are similar to skeletal muscle extracellular matrix have been shown to augment regeneration in ischemic muscle. In this study, treatment with a collagen-based matrix stimulated molecular myogenesis in an mdx murine model of necrosis. Matrix-treated animals ran ≥ 40% further, demonstrating functional regeneration, and expressed increased levels of myogenic transcripts. By contrast, matrix treatment was unable to induce transcriptional or functional changes in an MLC/SOD1G93A atrophic mouse model. In vitro, satellite cells were cultured under standard conditions, on matrix, in the presence of myocyte debris (to simulate a necrotic-like environment) or with both matrix and necrotic stimuli. Exposure …

Developing Social Skills Through Music: The Impact Of General Classroom Music In An Australian Lower Socio-Economic Area Primary School, John N. Heyworth

Research outputs 2013

Ideas about the physical and psychological healing effects of music date back to the classical Greek period. There is also substantial research concerning the educative influences of music on the human mind. Developmental deficiencies among low socio-economic student populations have often been associated with a reduced sense of self-esteem, responsibility, and ability to form relationships or engage in successful communication. This article describes a pro-active, constructivist approach to music education in a school largely attended by socially and economically disadvantaged students in Australia, and explores the influence of music on social learning. The strategic use of group music lessons in …

Research outputs 2013

To investigate the association of tag-SNPs and haplotype structures of the CIDEA gene with obesity in a Han Chinese population. Five single nucleotide polymorphisms (SNPs) (rs1154588/V115F, rs4796955/SNP1, rs8092502/SNP2, rs12962340/SNP3 and rs7230480/SNP4) in the CIDEA gene were genotyped in a case-control study. Genotyping was performed using the sequenom matrixassisted laser desorption/ionization time-of-flight mass spectrometry iPLEX platform. There were significant differences between the obese and control groups in genotype distributions of V115F (P>0.001), SNP1 (P = 0.006) and SNP2 (P = 0.005). Carriers of V115F-TT, SNP1-GG and SNP2-CC genotypes had a 2.84-fold (95 % CI 1.73-4.66), 2.19-fold (95 % CI 1.09-4.38) …

Pine As Fast Food: Foraging Ecology Of An Endangered Cockatoo In A Forestry Landscape, William Stock, Hugh Finn, Jackson Parker, Ken Dods

Research outputs 2013

Pine plantations near Perth, Western Australia have provided an important food source for endangered Carnaby’s Cockatoos (Calyptorhynchus latirostris) since the 1940s. Plans to harvest these plantations without re-planting will remove this food source by 2031 or earlier. To assess the impact of pine removal, we studied the ecological association between Carnaby’s Cockatoos and pine using behavioural, nutritional, and phenological data. Pine plantations provided high densities of seed (158 025 seeds ha21) over a large area (c. 15 000 ha). Carnaby’s Cockatoos fed throughout these plantations and removed almost the entire annual crop of pine cones. Peak cockatoo abundance coincided with …

Reversibility Of Membrane N-Glycome Of Hela Cells Upon Treatment With Epigenetic Inhibitors, Tomislav Horvat, Martina Dezeljin, Irma Redzic, Darko Barisic, Maja H. Bosnar, Gordan Lauc

Research outputs 2013

Glycans are essential regulators of protein function and are now in the focus of research in many physiological and pathophysiological processes. There are numerous modes of regulating their biosynthesis, including epigenetic mechanisms implicated in the expression of glyco-genes. Since N-glycans located at the cell membrane define intercellular communication as well as a cellular response to a given environment, we developed a method to preferentially analyze this fraction of glycans. The method is based on incorporation of living cells into polyacrylamide gels, partial denaturation of membrane proteins with 3 M urea and subsequent release of N-glycans with PNGase F followed by …

Trkb Receptor Signalling: Implications In Neurodegenerative, Psychiatric And Proliferative Disorders, Vivek K. Gupta, Yuyi You, Veer Gupta, Alexander Klistorner, Stuart L. Graham

Research outputs 2013

The Trk family of receptors play a wide variety of roles in physiological and disease processes in both neuronal and non-neuronal tissues. Amongst these the TrkB receptor in particular has attracted major attention due to its critical role in signalling for brain derived neurotrophic factor (BDNF), neurotrophin-3 (NT3) and neurotrophin-4 (NT4). TrkB signalling is indispensable for the survival, development and synaptic plasticity of several subtypes of neurons in the nervous system. Substantial evidence has emerged over the last decade about the involvement of aberrant TrkB signalling and its compromise in various neuropsychiatric and degenerative conditions. Unusual changes in TrkB signalling …

Research outputs 2013

Glycosylation of immunoglobulin G (IgG) influences IgG effector function by modulating binding to Fc receptors. To identify genetic loci associated with IgG glycosylation, we quantitated N-linked IgG glycans using two approaches. After isolating IgG from human plasma, we performed 77 quantitative measurements of N-glycosylation using ultra-performance liquid chromatography (UPLC) in 2,247 individuals from four European discovery populations. In parallel, we measured IgG N-glycans using MALDI-TOF mass spectrometry (MS) in a replication cohort of 1,848 Europeans. Meta-analysis of genome-wide association study (GWAS) results identified 9 genome-wide significant loci (P,2.2761029) in the discovery analysis and two of the same loci (B4GALT1 and …

Pathology Associated With Aav Mediated Expression Of Beta Amyloid Or C100 In Adult Mouse Hippocampus And Cerebellum, Eleanor S. Drummond, Jill Muhling, Ralph Martins, Linda K. Wijaya, Erich M. Ehlert, Alan R. Harvey

Research outputs 2013

Accumulation of beta amyloid (Ab) in the brain is a primary feature of Alzheimer’s disease (AD) but the exact molecular mechanisms by which Ab exerts its toxic actions are not yet entirely clear. We documented pathological changes 3 and 6 months after localised injection of recombinant, bi-cistronic adeno-associated viral vectors (rAAV2) expressing human Ab40- GFP, Ab42-GFP, C100-GFP or C100V717F-GFP into the hippocampus and cerebellum of 8 week old male mice. Injection of all rAAV2 vectors resulted in wide-spread transduction within the hippocampus and cerebellum, as shown by expression of transgene mRNA and GFP protein. Despite the lack of accumulation of …

The Guinea Pig As A Model For Sporadic Alzheimer's Disease (Ad): The Impact Of Cholesterol Intake On Expression Of Ad-Related Genes, Mathew Sharman, Seyyed H.M. Nik, Mengqi Chen, Daniel Ong, Linda K. Wijaya, Simon Laws, Kevin Taddei, Morgan Newman, Michael Lardelli, Ralph Martins, Guiseppe Verdile

Research outputs 2013

We investigated the guinea pig, Cavia porcellus, as a model for Alzheimer’s disease (AD), both in terms of the conservation of genes involved in AD and the regulatory responses of these to a known AD risk factor - high cholesterol intake. Unlike rats and mice, guinea pigs possess an Ab peptide sequence identical to human Ab. Consistent with the commonality between cardiovascular and AD risk factors in humans, we saw that a high cholesterol diet leads to up-regulation of BACE1 (b-secretase) transcription and down-regulation of ADAM10 (a-secretase) transcription which should increase release of Ab from APP. Significantly, guinea pigs possess …

Variability In The Carbon Storage Of Seagrass Habitats And Its Implications For Global Estimates Of Blue Carbon Ecosystem Service, Paul Lavery, Miguel-Angel Mateo, Oscar Serrano, Mohammad Rozaimi

Research outputs 2013

The recent focus on carbon trading has intensified interest in ‘Blue Carbon’–carbon sequestered by coastal vegetated ecosystems, particularly seagrasses. Most information on seagrass carbon storage is derived from studies of a single species, Posidonia oceanica, from the Mediterranean Sea. We surveyed 17 Australian seagrass habitats to assess the variability in their sedimentary organic carbon (Corg) stocks. The habitats encompassed 10 species, in mono-specific or mixed meadows, depositional to exposed habitats and temperate to tropical habitats. There was an 18-fold difference in the Corg stock (1.09– 20.14 mg Corg cm23 for a temperate Posidonia sinuosa and a temperate, estuarine P. australis …

Results indicate a significant improvement …

The Acceleration Of Aging And Alzheimer’S Disease Through The Biological Mechanisms Behind Obesity And Type Ii Diabetes, Ian J. Martins, Wei Ling F. Lim, Andrea C. Wilson, Simon M. Laws, Ralph Martins

Research outputs 2013

The incidence of diabetes is predicted to increase to 21% by 2050. Currently, one third of US adults are obese and over 11% of these individuals have diabetes. Due to the growing need for therapeutic intervention to control and/or stabilize this increase in the incidence of diabetes in Western communities, gaining a comprehensive understanding of the association between obesity and Type 2 diabetes has become increasingly important to diabetes research. The increased cell senescence associated with diabetes has been associated with the limited ability of cells to divide, with indication of telomere shortening and genomic instability of the cells. Obese …

Increased Risk For Obesity And Diabetes With Neurodegeneration In Developing Countries [Journal Article], Ian J. Martins

Research outputs 2013

The incidence of global obesity and Type 2 diabetes has increased and is predicted to rise to 30% of the global population. Diet and lifestyle factors are incapable to resolve the increased incidence for obesity and diabetes in various populations of the world. Developing countries have come to the forefront because of the higher diabetic epidemic. The urbanization may possibly provide an explanation for the global diabetic epidemic. In Western countries the metabolic syndrome and non alcoholic fatty liver disease (NAFLD) have reached 30 % of the population and now at present NAFLD afflicts 20% of developing populations. Western diets …

Exploring Ways To Improve Online Health News Stories, Trevor A. Cullen

Research outputs 2013

For a long time, reporting health consisted largely of statistics on the number of deaths and cases of disease, or reporting on epidemiological data that affects people we do not know. While this is important for health officials, it is of little interest to audiences who are increasingly demanding information that is useful to their daily lives. And conserving one’s health is perhaps the most useful of all topics. Many have now added the internet to their personal health toolbox, helping them to gain a better understanding of an illness or medical condition. But how accurate and balanced is the …

Roles Of Compressive Residual Stress In Enhancing The Corrosion Resistance Of Nano Nitride Composite Coatings On Steel, Xiaoli Zhao, Paul Munroe, Daryoush Habibi, Zonghan Xie

Research outputs 2013

Nanocomposite coatings were synthesized, and subsequently annealed, in an attempt to understand the influence of residual stress upon their resistance to corrosion under acidic attack. Pitting corrosion, originating from microscopic coating defects, was commonly identified in the coatings subject to annealing. Finite element analysis was used to map the residual stress distribution adjacent to these defects and quantify resulting geometrical changes. The results show that with the presence of compressive residual stress in the coatings, corrosion-initiated cracking along weak interfaces was suppressed, and structural integrity maintained. Moreover, compressive residual stress helped constrict pre-existing structural defects in columnar-structured coatings and, in …

This research evaluated the vulnerability and sustainability of the seagrass resource in an urbanized area to the effects of sea level rise. The assessment required analysis of information regarding the biogeography of the seagrass resource, and developing a method to model the spatial extent of the suitable habitat for seagrass, and applying the model to predict the implications of simulated sea level rise scenarios on the seagrass resource.

Examining the biogeography of the seagrass resource required the development of a seagrass monitoring and assessment field survey and a comprehensive …

A Case Study Of Jamaican Children's Lived Play Experiences, Carol Ann Long

USF Tampa Graduate Theses and Dissertations

Although research on children's play is abundant and considerable advances have been made in young children's play, the majority of these studies have been based in western developed countries and written from adults' perspectives rather than with children. Additionally, very little research has been done on children's play with active participants from smaller developing countries. The voices of society's youngest members have been lost or are only marginally represented.

The purpose of this qualitative research is to explore, understand, and describe young Jamaican children's lived play experiences as related through their eyes. The theoretical frameworks used to guide this study …

Efficacy Of A Dissonance-Based Intervention For Self-Objectification: A Randomized Controlled Trial, Jessie Erin Menzel

USF Tampa Graduate Theses and Dissertations

Self-objectification is the process by which women take on a third-person perspective in evaluating their physical appearance and sexual attributes. Objectification theory states that self-objectification may lead to negative mental health outcomes in women; a growing body of cross-sectional and experimental research supports the connection between self-objectification and the experience of shame, disordered eating, depression, and sexual dysfunction. This study sought to evaluate an intervention designed to reduce self-objectification behaviors and beliefs in order to prevent the development of disordered eating, depression, and sexual dysfunction. An efficacious prevention program using cognitive dissonance induction was adapted to target self-objectification. The efficacy …

Fate Of Polybrominated Diphenyl Ethers During Wastewater Treatment Process Producing Reclaimed Water, Kristy Siegel

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs), flame retardants, have been applied to consumer goods, such as furniture, electrical devices, textiles, and appliances for decades. Due to their physico-chemical properties, PBDEs are semi-volatile and easily leach off the consumer good during aging, stress, or normal wear and tear of the good. Once airborne, they pose an environmental health threat because they can adsorb onto dust particles, soil, or other particulates that can be inhaled, ingested, or come into contact with the dermal layer. Additionally, PBDEs have a molecular structure similar to other persistent organic pollutants, such as polychlorinated biphenyls and polychlorinated dibenzo-p-dioxins and …

Polybrominated Diphenyl Ethers In Sediments Within The Hillsborough Bay Watershed, Candice Simmons

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs) are a widely used class of flame retardants that are important sources for contamination in the marine environment. Sediments serve as a large reservoir for PBDEs due to their large sorption capacity. This research assessed the presence and distribution of PBDEs in Hillsborough Bay, a subdivision of Tampa Bay, FL, by determining levels in surface sediment samples, creating a historical profile of the contaminant in a sediment core taken from within the bay, and investigating sediment characteristics that control their distribution. Compositional patterns and temporal distributions of 8 of the 209 congeners of PBDEs (BDE-28, -47, …
