The genetic and molecular events associated with changes in muscle mass and function after SCI and after the implementation of candidate therapeutic approaches are still not completely known. The overall objective of this study was to identify key molecular pathways activated with muscle remodeling after SCI and locomotor training. We implemented treadmill training in a well-characterized rat model of moderate SCI and performed genome wide expression profiling on soleus muscles at multiple time points: 3, 8, and 14 days after SCI. We found that the activity of the protein ubiquitination and mitochondrial function related pathways was altered with SCI and …
Comparison Of Bacterial Flora In Fish Mucus And Lake Water, Robert W. Thomas
Comparison Of Bacterial Flora In Fish Mucus And Lake Water, Robert W. Thomas
Honors Theses, 1963-2015
Although commonly known for their ability to cause deadly infectious diseases, there are populations of bacteria (identified as normal flora) that symbiotically live on and amongst larger host organisms and positively impact survival of the host. In previous research, culturing methods suggest that freshwater fish (i.e. bluegill and northern pike) maintain a normal flora population and that this flora aids in protection and the health of the fish. Our study used Ion torrent PGM sequencing to identify a larger, more complete population of normal flora in 2 different lake samples from three different species of fish. Identifying and comparing the …
A Protective Role Of Autophagy In A Drosophila Model Of Friedreich's Ataxia (Frda), Luan Wang
A Protective Role Of Autophagy In A Drosophila Model Of Friedreich's Ataxia (Frda), Luan Wang
Wayne State University Dissertations
Friedreich’s ataxia (FRDA) is an inherited autosomal recessive neurodegenerative disease. It affects 1 in every 50,000 people in central Europe and North America. FRDA is caused by deficiency of Frataxin, an essential mitochondrial iron chaperone protein, and the associated oxidative stress damages. Autophagy, a housekeeping process responsible for the bulk degradation and turnover of long half-life proteins and organelles, is featured by the formation of double-membrane vacuoles and lysosomal degradation. Previous researches indicate that Danon’s disease, the inherited neural disorder disease that shares similar symptoms with FRDA, is due to the malfunction of autophagy. Based on this, we raise the …

There is a growing demand for genome-scale metabolic reconstructions for plants, fueled by the need to understand the metabolic basis of crop yield and by progress in genome and transcriptome sequencing. Methods are also required to enable the interpretation of plant transcriptome data to study how cellular metabolic activity varies under different growth conditions or even within different organs, tissues, and developmental stages. Such methods depend extensively on the accuracy with which genes have been mapped to the biochemical reactions in the plant metabolic pathways. Errors in these mappings lead to metabolic reconstructions with an inflated number of reactions and …

The Effects Of Clinorotation In The Host Plant, Medicago Truncatula, And Its Microbial Symbionts, Ariel Dauzart
Electronic Theses and Dissertations
The aim of this research was to understand mutualistic relationships between plants and endophytic microbes under the influence of an altered gravity vector. Understanding the outcome of the plant-microbe symbiosis in altered gravity is vital to developing life support systems for long distance space travel and colonization of other planets. This research utilized the model tripartite relationship among Medicago truncatula–Sinorhizobium meliloti–Rhizophagus irregularis. Plants were inoculated with rhizobial bacteria (S. meliloti), arbuscular mycorrhizal fungi (R. irregularis), both microbes, or none (microbial control), and placed on a rotating clinostat for 28 d. Vertical and horizontal static controls were also performed. Plant development …

Turkish Journal of Biology
The aim of this study was to compare the activity of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and total and selenium-dependent glutathione peroxidase (total GSH-Px and Se-GSH-Px) in the liver of wild boars (Sus scrofa) selected from a selenium-deficient area with respect to season of the year, sex, and age. Only season had a significant effect on liver Se content. Liver selenium concentration in the wild boars was highest in spring (0.292 µg/g wet weight) and lowest in winter (0.185 µg/g wet weight) (P < 0.05). The highest mean activity of total GSH-Px, Se-GSH-Px, and CAT (404.0, 309.9, and 1170.0 U/mg protein, respectively) was found in the spring season, and the respective highest mean activity of SOD was found during autumn (31.5 U/mg protein). Females showed markedly higher mean activities of total GSH-Px (388.2 and 314.7 U/mg protein) and CAT (1151.0 and 765.8 U/mg protein) compared to males. In comparison to other groups of animals, those aged between 1 and 1.5 years were characterized by higher mean activity of total GSH-Px and Se-GSH-Px, and those over 2 years of age showed higher activity of CAT and SOD. The analysis showed that the strongest oxidative stress and the greatest risk of peroxidative damage to the liver occurred during the winter.

Turkish Journal of Biology
Shoot tips of five tomato (Lycopersicon esculentum Mill.) genotypes were successfully cryopreserved by droplet vitrification. Recovered plants were studied for genetic stability by two different assays: amplified fragment length polymorphism (AFLP) using 4 primer combinations and sequencing of lycopene $\beta$-cyclase gene (LCY-B) from leaves. The highest shoot regeneration after cryopreservation was 70% (Pontica) following 24 h osmoprotection in 0.5 M sucrose and 30 min dehydration in plant vitrification solution 2 (PVS2). The data inferred from AFLP showed no genetic dissimilarities between in vitro regenerants derived from cryopreserved tissues compared with the noncryopreserved controls. Although a single nucleotide polymorphism, a G→T …

Effects Of Proline And Glycine On The Cnidocyte Discharge Of Hydra Magnipapillata, Janine R. Appleton
Effects Of Proline And Glycine On The Cnidocyte Discharge Of Hydra Magnipapillata, Janine R. Appleton
Honors Theses and Capstones
The sense of taste enables animals to utilize environmental cues to detect favorable foods. Through specialized sensory receptors, Cnidarians employ stinging cells called cnidocytes to perform a variety of activities such as locomotion, capturing prey, inducing of feeding responses, and defense. Their discharge is highly regulated by mechanical and chemical signals that are mediated by a complex system including the opsin and taste pathways. Taste 1 Receptors (T1R) have previously been isolated in vertebrates but only until recently, have been noted in invertebrates. Receptors specific to L- amino acids corresponding to the taste sensation of umami, were studied to determine …

Department of Biology Faculty Scholarship and Creative Works
The soil contamination legacy of postindustrial sites has become an issue of increasing ecological and public health concern. This study examines the ectomycorrhizal and above-ground plant relationships in the metaliferous soil of an urban brownfield. Ectomycorrhizal fungi (EMF) were microscopically identified by physical morphotyping followed by sequencing of ribosomal DNA. Plant productivity was assessed through Leaf Area Index (LAI) measurements taken fromMay through July 2012 and 2013. Results indicate that therewere significant changes in EMF community composition and plant productivity based on their position along a total soil metal load gradient. Cenococcum geophilum was the dominant species in the soilswhere …

Characterizing The Innate Immunity In The Hawaiian Coral Montipora Capitata, Melinda S. Ansley
Electronic Theses and Dissertations
Coral reefs are among the most diverse ecosystems in the world; however, they are quickly diminishing due to natural and anthropogenic stressors, including disease. Corals possess innate immune responses that aid in protection against these stressors. In several coral species, immune responses are inducible in response to stress. Montipora capitata is a predominant coral in Kaneohe Bay, Oahu, Hawaii. This coral occurs in two color morphs, orange and red, and is susceptible to the tissue loss disease Montipora white syndrome (MWS). MWS disease prevalence within Kaneohe Bay varies, with lower prevalence in the North than South Bay and with orange …
Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai
Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai
Theses and Dissertations--Toxicology and Cancer Biology
This work describes the fascinating interplay between two tumor suppressors Prostate apoptosis response-4 (Par-4) and p53. The guardian of the genome, p53, is frequently mutated in human cancers, and may contribute to therapeutic resistance. However, p53 is intact and functional in normal tissues, and we observed that specific activation of p53 in normal fibroblasts could induce apoptosis selectively in p53-deficient cancer cells. This paracrine apoptotic effect was executed by Par-4 secreted in response to p53 activation. Accordingly, activation of p53 in wild-type mice, but not in p53-/- or Par-4-/- mice, caused systemic elevation of Par-4 that induced apoptosis …
