Discovery & Born-Digital Archiving: Open Source Systems For Preservation And Access, L. Bryan Cooper, Margarita Perez-Martinez

Works of the FIU Libraries

The Everglades Explorer (EE) portal at http://ee.fiu.edu continues to evolve with the addition of the Internet Archive's Archive-It, and future planned alignment with the Digital Public Library of America (DPLA). The reasons for the development of the portal continue to exist, as originally perceived four years ago. Adaptations to ongoing change and system testing continues, and the use of Archive-It has broad institutional potential beyond EE. Cross-walking skills continue to grown, and will benefit future syndication and discovery system integration. The metadata normalization and harmonization will help save time for the end-user. Preservation and access to ...


Autophagy And Its Potential Role In Stress And Feed Efficiency Using Avian Lines, Alissa Laura Piekarski Dec 2015

Autophagy And Its Potential Role In Stress And Feed Efficiency Using Avian Lines, Alissa Laura Piekarski

Theses and Dissertations

Autophagy is a highly conserved cellular mechanism that is responsible for the degradation and recycling of damaged organelles. Recently, autophagy has been involved in critical roles during overall development of the organism and degradation of damaged cellular components. This pathway has witnessed dramatic growth in the last few years and has been extensively studied in yeast and mammals, however, there is a paucity of information in avian (non-mammalian) species. First, we characterized genes involved in the autophagy pathway in male and female Jungle Fowl to determine gender and tissue specific differences. Secondly, tissue and genotype differences in Japanese quail selected ...


Transcriptomics Of Chicken Primordial Germ Cells, Nhung Thi Nguyen Dec 2015

Transcriptomics Of Chicken Primordial Germ Cells, Nhung Thi Nguyen

Theses and Dissertations

Chicken primordial germ cells (PGCs) are derived from extraembryonic tissue of the embryo and first appear at stage X of development. They enter the bloodstream and migrate to the genital ridge, unite with somatic tissue to form a developing gonad, and then differentiate to sperm or ova (Fujimoto et al., 1976). Understanding molecular features of both male and female PGCs not only clarify the differentiation mechanism of such cells toward different germ lines, but will also help in selecting for highly productive types of commercial chicken. Most previous studies focused on the location of PGCs (Eyal-Giladi et al., 1981; Swift ...

In Vivo Periodical Monitoring Of Immune Cell Infiltration In Response To Feathers And Intramuscular Injection Of Ionps Using The Pulp (Dermis) Of Growing Feathers As Test Site Tissue In Chickens, Olfat Taleb Alaamri

Theses and Dissertations

The applications of nanoparticles are growing, but little is known about their interactions with the immune system as most studies did not use suitable in vivo test systems. The purpose of these studies was to investigate the utility of chicken growing feathers as an in vivo test site for iron oxide nanoparticle (IONP) interactions with the immune system. The first objective of this study was to monitor leukocyte infiltration into the growing feather pulp upon the administration of IONP and IO-mIgG preparations. The second objective was to test the utility of IONPs as vaccine adjuvants by monitoring primary and memory ...


Leptin Regulates The Expression Of Autophagy-Related Genes In Chickens, Peter Olawale Ishola Dec 2015

Leptin Regulates The Expression Of Autophagy-Related Genes In Chickens, Peter Olawale Ishola

Theses and Dissertations

Autophagy or cellular self-digestion, a lysosomal degradation pathway that is conserved from yeast to human, plays a key role in recycling cellular constituents, including damaged organelles. It also plays a pivotal role in the adaptation of cells to a plethora of distinct stressors including starvation. Autophagy has been extensively studied in mammals and yeast, but little is known in avian species. Thus, the major objective of the present study was to determine the effects of leptin on autophagy-related genes in chicken hypothalamus, muscle and liver. Leptin is an adipocytokine that is mostly produced by white adipose cells in mammals (as ...


Evaluation Of Reproductive Strategies In Captive California Yellowtail (Seriola Dorsalis) Using Genetic Parentage Analyses, Elizabeth K. Smith, Mark Drawbridge Ms, John Hyde Phd, Geoffrey Morse Phd Sep 2015

Evaluation Of Reproductive Strategies In Captive California Yellowtail (Seriola Dorsalis) Using Genetic Parentage Analyses, Elizabeth K. Smith, Mark Drawbridge Ms, John Hyde Phd, Geoffrey Morse Phd

Theses

A good understanding of spawning dynamics of species in aquaculture is vital in order to maximize egg production and quality as well as efficient allocation of food and space resources. The breeding program of California yellowtail (CYT; Seriola dorsalis previously Seriola lalandi) at Hubbs-SeaWorld Research Institute (HSWRI) is set up such that up to 30 wild caught brood fish can broadcast spawn in a group setting, just as CYT reproduce in the wild. The population of brood fish were originally caught offshore from Southern California, and are maintained under ambient sea water and natural lighting conditions. The spawning season at ...

Wintering Bald Eagle Count Trends In The Conterminous United States, 1986-2010, Wade L. Eakle, Laura Bond, Mark R. Fuller, Richard A. Fischer, Karen Steenhof

Biomolecular Research Center Publications and Presentations

We analyzed counts from the annual Midwinter Bald Eagle Survey to examine state, regional, and national trends in counts of wintering Bald Eagles (Haliaeetus leucocephalus) within the conterminous 48 United States from 1986 to 2010. Using hierarchical mixed model methods, we report trends in counts from 11 729 surveys along 844 routes in 44 states. Nationwide Bald Eagle counts increased 0.6% per yr over the 25-yr period, compared to an estimate of 1.9% per yr from 1986 to 2000. Trend estimates for Bald Eagles were significant (P ≤ 0.05) and positive in the northeastern and northwestern U.S ...


Manipulating Adipose Tissue Fatty Acid Oxidation To Reduce Fatness In Broiler Chickens, Tania Emmanuelle Torchon Aug 2015

Manipulating Adipose Tissue Fatty Acid Oxidation To Reduce Fatness In Broiler Chickens, Tania Emmanuelle Torchon

Masters Theses

Compared to rodents, broiler chickens, those reared for meat, are an attractive model for studies of adipose biology, and obesity development in children. The broiler chicken lacks the gene for uncoupling protein 1, the hallmark for brown adipose tissue making them a useful model to study lipid metabolism in white adipocytes. Two studies were performed to investigate if white adipose tissue had the metabolic ability for fatty acid oxidation (FAO), and to investigate the effects of dietary fatty acids on abdominal fat development of young broiler chickens as a model for childhood obesity. In study one, chickens were fasted for ...


Differences In Response To Hypoxia In The Three-Spined Stickleback From Lotic And Lentic Localities: Dominance And An Anaerobic Metabolite, L. U. Sneddon, J. Yerbury Jun 2015

Differences In Response To Hypoxia In The Three-Spined Stickleback From Lotic And Lentic Localities: Dominance And An Anaerobic Metabolite, L. U. Sneddon, J. Yerbury

Lynne U. Sneddon, Ph.D.

Dominance hierarchies of the three-spined stickleback Gasterosteus aculeatus from river and pond populations were subjected to hypoxia (20%, range±1%). Under hypoxia, the hierarchies were less stable in terms of rank position and tissue L-lactate was higher in river fish than pond fish under normoxia and hypoxia. Dominant fish gained mass under normoxia but lost mass under hypoxic conditions possibly due to them maintaining high levels of aggression.

Jibin Zhang

Secretoryfactors in animals play an important role in communication between different cells, tissues and organs. Especially, the secretoryfactors with specific expression in one tissue may reflect important functions and unique status of that tissue in an organism. In this study, we identified potential tissue-specificsecretoryfactors in the fat, muscle, heart, lung, kidney and liver in the mouse by analyzing microarray data from NCBI's Gene Expression Omnibus (GEO) public repository and searching and predicting their subcellular location in GeneCards and WoLF PSORT, and then confirmed tissue-specific expression of the genes using semi-quantitative PCR reactions. With this approach, we confirmed 11 lung ...

Choosing content for this discovery portal is comparable to past scholarly practice of creating and publishing subject bibliographies, except metadata and data are ...


The Development Of Skeletal Muscle In Young Horses: An Ultrasonography And Satellite Cell Approach, Emma K. Lavigne May 2015

The Development Of Skeletal Muscle In Young Horses: An Ultrasonography And Satellite Cell Approach, Emma K. Lavigne

Honors Scholar Theses

Muscle growth in young horses is characterized by an increase in muscle cross-sectional area, which can be accomplished through the activation and differentiation of satellite cells. Satellite cells can be stimulated or inhibited in response to different cytokines and growth factors and are key mediators of muscle hypertrophy and regeneration. The aim of this study was to investigate the growth of the longissimus dorsi (LD) muscle in horses under 5 years of age and to obtain preliminary data on satellite cell behavior in foals. The area, width, height, and subcutaneous fat were measured using ultrasonography at 6-month increments over the ...


Development Of Genetic Goat And Hamster Models Of Atrial Fibrillation And Long Qt Syndrome; And Genetic Hamster Models Of Middle East Respiratory Syndrome, Dane A. Rasmussen May 2015

Development Of Genetic Goat And Hamster Models Of Atrial Fibrillation And Long Qt Syndrome; And Genetic Hamster Models Of Middle East Respiratory Syndrome, Dane A. Rasmussen

All Graduate Theses and Dissertations

Atrial fibrillation, long QT syndrome, and Middle East Respiratory Syndrome are three deadly human diseases for which genetic animal models are needed. From elucidating disease pathogenesis to facilitating the development of treatments, animal models are crucial for studying human disease. One of the most effective ways to generate specific animal models is through genetic modification. Historically, mice have been most widely used as genetically modified models, despite a number of limitations. New gene editing technologies such as CRISPR/Cas9 have made developing alternative genetic models that better recapitulate some human diseases better and more feasible. In this thesis, I describe ...


The Dietary Ecology Of Ring-Tailed Lemurs As Reflected By Δ13c And Δ15n Stable Isotope Values, Kristin Lilla Schwagerl Apr 2015

The Dietary Ecology Of Ring-Tailed Lemurs As Reflected By Δ13c And Δ15n Stable Isotope Values, Kristin Lilla Schwagerl

Anthropology Graduate Theses & Dissertations

Madagascar is one of the top global hotspots for biodiversity (Yoder & Nowak, 2006). Yet it is experiencing high rates of habitat loss, especially gallery forest, an important resource to many endemic primate species (Sauther et al., 1999; Sussman & Rakotozafy, 1994). Natural disasters such as Madagascar's cyclical droughts and cyclones may compound the effects of habitat loss (Gould et al., 1999; Whitelaw, 2010; Wright, 1999). Changes in dietary ecology as a result of these events may be reflected in altered hair δ13C and δ15N values from the study population. By studying how lemurs respond to cyclone and drought habitat disturbance, researchers can better understand how forest destruction and non-native species introduction by humans might impact the ability of lemurs to effectively react for continued survival.

This study looks at the effects of habitat disturbance on four endemic Malagasy ring-tailed lemur troops via stable carbon and ...

Nanoscale Reagents For The Detection And Treatment Of Tuberculosis In Resource Limited Regions, Candice Ashley Smith Jan 2015

Nanoscale Reagents For The Detection And Treatment Of Tuberculosis In Resource Limited Regions, Candice Ashley Smith

Chemistry & Biochemistry Graduate Theses & Dissertations (1986-2018)

Tuberculosis (TB) remains the second deadliest infectious disease after HIV/AIDS. TB most stubbornly has been spreading in resource limited regions. People in these regions need diagnostics and therapeutics tailored to their available resources. Developing countries would best benefit from a diagnostic that is robust, gives quick results, and requires minimal electricity or materials. Likewise, a high impact therapeutic for these communities would promote patient compliance through oral administration and low toxicity. In this thesis work, these challenges are confronted by development of an orally bioavailable gold nanoparticle platform, a surface enhanced Raman spectroscopy assay for the detection of an ...


Repeated Stressors In Adulthood Increase The Rate Of Biological Ageing, Michaela Hau, Mark F. Haussmann, Timothy J. Greives, Christa Matlack, David Costantini, Michael Quetting, James S. Adelman, Ana C. Miranda, Jesko Partecke Jan 2015

Repeated Stressors In Adulthood Increase The Rate Of Biological Ageing, Michaela Hau, Mark F. Haussmann, Timothy J. Greives, Christa Matlack, David Costantini, Michael Quetting, James S. Adelman, Ana C. Miranda, Jesko Partecke

James S. Adelman

Individuals of the same age can differ substantially in the degree to which they have accumulated tissue damage, akin to bodily wear and tear, from past experiences. This accumulated tissue damage reflects the individual’s biological age and may better predict physiological and behavioural performance than the individual‘s chronological age. However, at present it remains unclear how to reliably assess biological age in individual wild vertebrates. We exposed hand-raised adult Eurasian blackbirds (Turdus merula) to a combination of repeated immune and disturbance stressors for over one year to determine the effects of chronic stress on potential biomarkers of biological ...

A Comparative Analysis Of The Moose Rumen Microbiota And The Pursuit Of Improving Fibrolytic Systems., Suzanne Ishaq Pellegrini Jan 2015

A Comparative Analysis Of The Moose Rumen Microbiota And The Pursuit Of Improving Fibrolytic Systems., Suzanne Ishaq Pellegrini

Graduate College Dissertations and Theses

The goal of the work presented herein was to further our understanding of the rumen microbiota and microbiome of wild moose, and to use that understanding to improve other processes. The moose has adapted to eating a diet of woody browse, which is very high in fiber, but low in digestibility due to the complexity of the plant polysaccharides, and the presence of tannins, lignin, and other plant-secondary compounds. Therefore, it was hypothesized that the moose would host novel microorganisms that would be capable of a wide variety of enzymatic functions, such as improved fiber breakdown, metabolism of digestibility-reducing or ...
