Physiological Recordings Of High And Low Output Nmjs On The Crayfish Leg Extensor Muscle, Wenhui Wu, Robin L. Cooper

Biology Faculty Publications

We explain in detail how to expose and conduct electrophysiological recordings of synaptic responses for high (phasic) and low (tonic) output motor neurons innervating the extensor muscle in the walking leg of a crayfish. Distinct differences are present in the physiology and morphology of the phasic and tonic nerve terminals. The tonic axon contains many more mitochondria, enabling it to take a vital stain more intensely than the phasic axon. The tonic terminals have varicosities, and the phasic terminal is filiform. The tonic terminals are low in synaptic efficacy but show dramatic facilitated responses. In contrast, the phasic terminals are …

New Insights Into The Organization, Recombination, Expression And Functional Mechanism Of Low Molecular Weight Glutenin Subunit Genes In Bread Wheat, Lingli Dong, Xiaofei Zhang, Dongcheng Liu, Huajie Fan, Jiazhu Sun, Zhongjuan Zhang, Huanju Qin, Bin Li, Shanting Hao, Zhensheng Li, Daowen Wang, Aimin Zhang, Hong Qing Ling

Faculty Publications

The bread-making quality of wheat is strongly influenced by multiple low molecular weight glutenin subunit (LMW-GS) proteins expressed in the seeds. However, the organization, recombination and expression of LMW-GS genes and their functional mechanism in bread-making are not well understood. Here we report a systematic molecular analysis of LMW-GS genes located at the orthologous Glu-3 loci (Glu-A3, B3 and D3) of bread wheat using complementary approaches (genome wide characterization of gene members, expression profiling, proteomic analysis). Fourteen unique LMW-GS genes were identified for Xiaoyan 54 (with superior bread-making quality). Molecular mapping and recombination analyses revealed that the three Glu-3 loci …

Landscape should be an instrument of cultural force. This work contemplates the relationship between the artificial and the natural. It resulted from thinking about matters concerning my interactions with public space; the combination of nature and the culture we inflict upon it. By including "nature" here, I use it to denote an outside environment that includes biological activity that is untamed, yet still capable of being influenced by human agency. This human agency takes the form of culture, that which appropriates nature towards our social needs. Hence, this agency benefits the formation of landscapes. A cultural artifact such as an …

Work Towards The Isolation And Characterization Of The Muscle Isoform Of Glucose 1,6-Bisphosphatase, Caleb J. Hiller

Theses and Dissertations

Glucose 1,6-bisphosphate is an important small molecule involved in the regulation of glycolysis. Four enzymes synthesize this compound. One enzyme is known to degrade it, glucose 1,6-bisphosphatase. Other groups have produced work that indicates that there are two isoforms of this enzyme, one predominant in the brain and one in the muscle. This thesis contains the work performed in attempts to isolate and characterize the muscle isoform of glucose 1,6-bisphosphatase. While this enzyme was not isolated, much was learned about it and the results from this work may help in the future identification of this enzyme.

Self-Protecting Bactericidal Titanium Alloy Surface Formed By Covalent Bonding Of Daptomycin Bisphosphonates., Chang-Po Chen, Eric Wickstrom

Department of Biochemistry and Molecular Biology Faculty Papers

Infections are a devastating complication of titanium alloy orthopedic implants. Current therapy includes antibiotic-impregnated bone cement and antibiotic-containing coatings. We hypothesized that daptomycin, a Gram-positive peptide antibiotic, could prevent bacterial colonization on titanium alloy surfaces if covalently bonded via a flexible, hydrophilic spacer. We designed and synthesized a series of daptomycin conjugates for bonding to the surface of 1.0 cm² Ti6Al4V foils through bisphosphonate groups, reaching a maximum yield of 180 pmol/cm². Daptomycin-bonded foils killed 53 ± 5% of a high challenge dose of 3 × 10⁵ cfu Staphylococcus aureus ATCC 29213.

Modern Variation In Predation Intensity: Constraints On Assessing Predator-Prey Relationships In Paleoecologic Reconstructions, James Funderburk

USF Tampa Graduate Theses and Dissertations

The complex interaction between predators and their prey is rarely preserved in the fossil record. However, predation of marine mollusks by drilling gastropods leaves a diagnostic hole in the shell of the prey, possibly allowing for quantitative analysis of this ecological interaction. Drilling frequency, as measured in marine mollusks both in the Modern and fossil record, has been heralded as a potential opportunity to quantify these ecological interactions and use these values in the testing of hypotheses.

This study employed the collection, tallying, and analysis of bulk samples derived from shelly deposits on 45 Modern beaches along the contiguous coast …

Network Analysis And Comparative Phylogenomics Of Micrornas And Their Respective Messenger Rna Targets Using Twelve Drosophila Species, M Ryan Woodcock

Theses and Dissertations

MicroRNAs represent a special class of small (~21–25 nucleotides) non-coding RNA molecules which exert powerful post-transcriptional control over gene expression in eukaryotes. Indeed microRNAs likely represent the most abundant class of regulators in animal gene regulatory networks. This study describes the recovery and network analyses of a suite of homologous microRNA targets recovered through two different prediction methods for whole gene regions across twelve Drosophila species. Phylogenetic criteria under an accepted tree topology were used as a reference frame to 1) make inference into microRNA-target predictions, 2) study mathematical properties of microRNA-gene regulatory networks, 3) and conduct novel phylogenetic analyses …

Effects Of Diabetic State And Gender On Pro-Inflammatory Cytokine Secretion By Human Macrophages Infected With Burkholderia Pseudomallei, Annette J. Blam

Theses and Dissertations

Burkholderia pseudomallei is a gram-negative opportunistic soil pathogen that causes the life-threatening disease melioidosis. It is endemic in Northern Australia and Southeast Asia but can be found throughout many other regions in the world. Diabetes mellitus is a predisposing risk factor for infection with this organism and it has been demonstrated that diabetic males are particularly susceptible to severe infection. Previous research suggested that monocytes isolated from the whole blood of diabetic males demonstrated a decreased ability to produce the proinflammatory cytokines IL-1β and IL-8. We hypothesized that monocyte-derived macrophages from diabetic males would also secrete lower levels of pro-inflammatory …

Alterations In Mglur5 Expression And Signaling In Lewy Body Disease And In Transgenic Models Of Alpha- Synucleinopathy – Implications For Excitotoxicity, Diana L. Price, Edward Rockenstein, Kiran Ubhi, Van Phung, Natalie Maclean-Lewis, David A. Askay, Anna Cartier, Brian Spencer, Christina Patrick, Paula Desplats, Mark H. Ellisman, Eliezer Masliah

Communication Studies

Dementia with Lewy bodies (DLB) and Parkinson’s Disease (PD) are neurodegenerative disorders of the aging population characterized by the abnormal accumulation of alpha-synuclein (alpha-syn). Previous studies have suggested that excitotoxicity may contribute to neurodegeneration in these disorders, however the underlying mechanisms and their relationship to alpha-syn remain unclear. For this study we proposed that accumulation of alpha-syn might result in alterations in metabotropic glutamate receptors (mGluR), particularly mGluR5 which has been linked to deficits in murine models of PD. In this context, levels of mGluR5 were analyzed in the brains of PD and DLB human cases and alpha-syn transgenic (tg) …

Carbon Isotope Compositions Of Terrestrial C3 Plants As Indicators Of (Paleo)Ecology And (Paleo)Climate, Matthew J. Kohn

Geosciences Faculty Publications and Presentations

A broad compilation of modern carbon isotope compositions in all C3 plant types shows a monotonic increase in δ¹³C with decreasing mean annual precipitation (MAP) that differs from previous models. Corrections for temperature, altitude, or latitude are smaller than previously estimated. As corrected for altitude, latitude, and the δ¹³C of atmospheric CO₂, these data permit refined interpretation of MAP, paleodiet, and paleoecology of ecosystems dominated by C3 plants, either prior to 7–8 million years ago (Ma), or more recently at mid- to high latitudes. Twenty-nine published paleontological studies suggest preservational or scientific bias toward …
