Diet Analysis Of Gastrotricha, Mikhail Anfinson
Diet Analysis Of Gastrotricha, Mikhail Anfinson
S.U.R.E Posters
The phylum Gastrotricha is comprised of small aquatic organisms that live in between sand grains. It has been shown that meiofauna communities can play valuable roles in ecosystems and serve as a food source for animals higher up the trophic levels. However, little is known about their own feeding behavior which this study is concerned about. Over the summer developments were made in the methodical sections for diet diagnostic PCR for marine bacterial strains, unicellular marine eukaryotes, and investigating different types of immunofluorescence for marine bacteria. We also plan at looking at the number of sarcomeres within the pharynx of …
Nutrient Limitation In Freshwater Streams In The South Carolina Piedmont, Rachael Rowe
Nutrient Limitation In Freshwater Streams In The South Carolina Piedmont, Rachael Rowe
S.U.R.E Posters
Availability of nutrients, particularly nitrogen (N) and phosphorus (P), is a key driver of microbial growth and metabolism in freshwater ecosystems. Microbial biofilms composed of both autotrophs and heterotrophs play crucial roles in freshwater food webs. These stream communities may be limited by N, P, or both N and P. This project examined nutrient limitation of biofilm communities in two small, freshwater streams in the Catawba river basin within the Catawba Nation in South Carolina. Stream conditions were monitored and nutrient concentrations for ambient ammonium and phosphate were monitored. We quantified nutrient limitation, community respiration, gross primary production, and ash-free …
The Effect Of Semaphorin 3a On Chick Embryo Retinal Growth Cones, Allison T. Reed
The Effect Of Semaphorin 3a On Chick Embryo Retinal Growth Cones, Allison T. Reed
S.U.R.E Posters
During embryonic development, axons grow from the retina of the eye to the tectum of the brain which allows for visual information transfer. Axons travel to the tectum via axon pathfinding, which is influenced by axon guidance cues. Axon guidance molecules interact with the growing tips of retinal ganglion cell (RGC) axon, which are motile structures known as growth cones. Some inhibitory axon guidance molecules are known to cause a growth cone to collapse, where they cease growth and then retract, or turn away. One such inhibitory axon guidance molecule is Semaphorin 3A (Sema 3A). While Sema 3A’s importance is …
Testing The Allelic Strength Of Drosophila Melanogaster Mus109 Alleles, Erica V. Nestore
Testing The Allelic Strength Of Drosophila Melanogaster Mus109 Alleles, Erica V. Nestore
S.U.R.E Posters
Drosophila melanogaster, commonly referred to as fruit flies, possess a group of genes that when mutated can cause sensitivity to DNA damaging agents. These mutagen sensitive (mus) genes are likely involved in DNA repair, and one of these genes, mus109, was the focus of this study. To perform the experiment, complementation crosses were set up between the three mus109 alleles: mus109lS, mus109D1 and mus109D2. The wild-type DGRP-59 was used as the control. For each cross, twenty vials were scored. Brood one contained ten vials that were mock treated with distilled water, and …
Investigating Cytotoxicity And Defense Functions Of Bacteriophage Larva Genes In Host Mycobacterium Smegmatis, Dallas K. Nivens, Laela A. Walker
Investigating Cytotoxicity And Defense Functions Of Bacteriophage Larva Genes In Host Mycobacterium Smegmatis, Dallas K. Nivens, Laela A. Walker
S.U.R.E Posters
It is estimated that approximately 75% of gene functions within any given phage cluster remain unknown. Two phage traits that can be measured phenotypically were investigated: cytotoxicity, which causes host cell lysis, and superimmunity, which results in protection of the host from infection by similar phages. Five genes (35, 42, 46, 49, and 59), from a subcluster K5 bacteriophage named Larva, were amplified by the polymerase chain reaction (PCR) and assembled into a cloning plasmid (pExTra) using isothermal assembly. Initially, chemical transformation of Escherichia coli with the pExTra + gene insert, enabled amplification of the plasmids. Clonal PCR …
Recellularization Of Porcine Internal Thoracic Arteries As A Tissue Engineered Small-Diameter Vascular Graft Alternative, Carlos E. Escoto-Diaz, Jesse B. Kooistra, Nicholle E. Lewis, Holdyn C. Ferguson
Recellularization Of Porcine Internal Thoracic Arteries As A Tissue Engineered Small-Diameter Vascular Graft Alternative, Carlos E. Escoto-Diaz, Jesse B. Kooistra, Nicholle E. Lewis, Holdyn C. Ferguson
S.U.R.E Posters
Small-diameter vascular grafts are the leading treatment for myocardial infarctions resulting from atherosclerosed coronary vasculature. A potential alternative to using patient-derived grafts is the use of tissue engineered vessels. The removal of native cells from xenogenic vessels allows for recellularization with human cells types; however, the decellularization process depends on the use of cytotoxic reagents that must be removed prior to recellularization. The recellularization process must produce a functional graft that contains the multiple cell types found within arteries. We hypothesized that porcine internal thoracic arteries decellularized using a combination of detergents could be processed to support human endothelial and …
Exploring The Mechanisms Regulating Toroid Formation By Adipose-Derived Stem Cells Cultured On 3d Collagen Hydrogels, Mary-Catherine Cobb
Exploring The Mechanisms Regulating Toroid Formation By Adipose-Derived Stem Cells Cultured On 3d Collagen Hydrogels, Mary-Catherine Cobb
S.U.R.E Posters
Mesenchymal stem cells (MSCs) are a huge topic of interest to many researchers due to their therapeutic potential. MSCs can be harvested from various body tissues, including bone marrow, blood, and adipose tissue. Adipose-derived mesenchymal stem cells (ADSCs) are of particular therapeutic interest due to their great abundance and ease of accessibility relative to other types of MSCs. We have observed that ADSCs will migrate and self-organize into a toroid when applied to the top of a 3D type I collagen hydrogel. ADSCs fail to form toroids when embedded within collagen hydrogels, which raises the question of what specific environmental …
Generation Of Fluorescent Esophageal Adenocarcinoma Cells For Lineage Tracing Within Composite 3d Culture Models, Madeline G. Linker
Generation Of Fluorescent Esophageal Adenocarcinoma Cells For Lineage Tracing Within Composite 3d Culture Models, Madeline G. Linker
S.U.R.E Posters
While relatively rare, the aggressive nature and poor prognosis associated with esophageal carcinoma make it a particularly dangerous form of cancer. One approach to discovering esophageal cancer treatment options includes the development of composite 3D culture models. This method of research allows cellular interactions and responses toward interventions to be evaluated within a more complex system than 2D cultures. Additionally, a composite 3D model provides a higher throughput and is more cost-effective than in vivo animal studies. To analyze the interactions between the model’s cell types, fluorescent labeling allows each cell type to be distinguished from the others, facilitating independent …
