Analysis Of Botulinum Toxin A And Interacting Proteins In Skeletal Muscle Cells: An Investigation Into The Mechanisms Of Botulinum Toxin A As A Treatment For Chronic Exertional Compartment Syndrome, Lauren R. Kee

ELAIA

Background Chronic exertional compartment syndrome (CECS) is a condition in which muscle tissue expands against the surrounding fascia during activity and is compressed along with the nerves and blood vessels within the muscle compartment, leading to abnormally high intracompartmental pressure (ICP) and debilitating pain. Treatment typically includes fasciotomy, which results in significant levels of CECS recurrence; however, botulinum toxin A (BoNT-A) injection has recently been seen to decrease both ICP and pain through an unknown mechanism with little to no recurrence. Methods In this study, PyRosetta was used to model the probability of docking interaction between BoNT-A light or heavy …

Rna World And The Development Of Rna Protocells, Benjamin C. Mayfield

PANDION: The Osprey Journal of Research and Ideas

Origins of life research, also known as pre-biotic chemistry or astrobiology, aims to unravel the mystery of the first cell’s origin on Earth. This interdisciplinary field encompasses biology, chemistry, and physics, with the primary goal of understanding the conditions necessary for life to emerge from abiotic environments. The RNA world hypothesis suggests that early life initially used RNA instead of DNA to store genomic information and for enzymatic functions. Protocells, membrane-bound entities with metabolic processes and self-replication capabilities, likely preceded the emergence of true cells. The challenges associated with RNA world is currently an active field of research. Advancements in …

Therapies For Mitochondrial Disorders, Kayli Sousa Smyth, Anne Mulvihill

SURE Journal: Science Undergraduate Research Experience Journal

Mitochondria are cytoplasmic, double-membrane organelles that synthesise adenosine triphosphate (ATP). Mitochondria contain their own genome, mitochondrial DNA (mtDNA), which is maternally inherited from the oocyte. Mitochondrial proteins are encoded by either nuclear DNA (nDNA) or mtDNA, and both code for proteins forming the mitochondrial oxidative phosphorylation (OXPHOS) complexes of the respiratory chain. These complexes form a chain that allows the passage of electrons down the electron transport chain (ETC) through a proton motive force, creating ATP from adenosine diphosphate (ADP). This study aims to explore current and prospective therapies for mitochondrial disorders (MTDS). MTDS are clinical syndromes coupled with abnormalities …

Ngly1 Deficiency Affects Glycosaminoglycan Biosynthesis And Wnt Signaling Pathway In Mice, Amy Batten

PANDION: The Osprey Journal of Research and Ideas

Individuals affected by NGLY1 Deficiency cannot properly deglycosylate and recycle certain proteins. Even though less than 100 people worldwide have been diagnosed with this rare autosomal recessive condition, thousands are affected by similar glycosylation disorders. Common phenotypic manifestations of NGLY1 Deficiency include severe neural and intellectual delay, impaired muscle and liver function, and seizures that may become intractable. Very little is currently known about the various mechanisms through which NGLY1 deficiency affects the body and this has led to a lack of viable treatment options for those afflicted. This experiment uses a loss-of-function (LOF) mouse model of NGLY1 Deficiency homologous …

Altering Sensory Learning By Chronic Inactivation Of Vip Interneurons, Christopher Alba, Hannah Selwyn, Katie Ferguson, Jessica Cardin

The Yale Undergraduate Research Journal

Vasoactive intestinal polypeptide-expressing interneurons (VIP-INs) play a key role in the regulation of cortical circuits and are implicated in perceptual function and psychiatric disease. However, their role in perceptual augmentation and learning remains understudied. We performed chronic, localized ablation of VIP-INs in the primary visual cortex of adult mice using caspase-induced apoptosis to better understand how VIP-INs contribute to visual perception and the ability to learn a visual detection task. We find that chronic VIP-IN ablation does not affect naïve performance on a full-screen visual contrast detection task. However, mice with suppressed levels of VIP-INs achieved their final expert state …

The Effect Of Alcalase Concentration On The Proteins From The Shells Of Litopenaeus Setiferus (White Shrimp), Liam T. Quan

Journal of the South Carolina Academy of Science

Chitin is a naturally abundant polymer that also happens to be biodegradable. Chitin can be used in a variety of different products such as biodegradable plastics, papers, medical products, foods, and medical treatments. To extract chitin, shells must be demineralized and deproteinized. The goal of this experiment was to examine the effect of the protease Alcalase in the deproteinization of litopenaeus setiferus shells. The hypothesis was that if the concentration of Alcalase increased, then the absorbance of proteins in the spectrophotometer reading would increase. The null hypothesis was that if the concentration increased there would be no change in absorption. …

Soil Moisture And Porosity Affects The Abundance And Distribution Of Ageratum Houstonianum, Sahar Fattani, Christabel-Anne Forka, Monique Garcia, Thao Huynh, Torre Merricks, Morgan Robinson, Charcacia Sanders

Pursue: Undergraduate Research Journal

Introduction: Ageratum houstonianum is an herbaceous, drought-tolerant plant also known as Blue billygoat weed. It grows well in drained soil and shaded areas. Soil moisture and porosity are two abiotic factors that affect the abundance and distribution of A. houstonianum. An ideal condition for plants to grow includes a greater amount of soil moisture and porosity. Higher porosity would mean that there is a greater number of pores, which would result in more significant plant nutrients because of its ability to retain more water. The purpose of this research was to see how soil moisture and porosity based on …

Insect Population Dynamics, Varietal Preference And Performance Of Organic Bio-Pesticides, Anitha Chitturi, Jeanine Davis, Margaret Bloomquist, Franklin Quarcoo, Kokoasse Kpomblekou-A, Desmond Mortley

Professional Agricultural Workers Journal

Abstract

Organic farming prohibits use of synthetic agrochemicals and encourages use of Integrated Pest Management (IPM) methods. States in the Southeastern US generally lag behind the rest of the country in organic vegetable production partly because of high insect pressures that make it difficult to grow vegetables without pesticides. This study on summer squash (Cucurbita pepo), grown using organic management practices, was conducted at a research station located in Mills River, North Carolina. The objectives of the study were to assess insect population dynamics and to evaluate performance of three OMRI-approved bio-pesticides: Azadirachtin, Pyrethrin and Spinosad against major …

Of Course, Humans Are Not Unique!, Bernard Wallner

Animal Sentience

This commentary focuses on the question of the uniqueness of humans in comparison to other species and on the false assumption that single arguments support logical conclusions. Comparative analysis of genetic data in humans and nonhuman primates regarding the dopaminergic system of the subcortical mesolimbic reward system highlights homologous traits shared and modified by the process of evolution. Such an analytical approach is more relevant than claims of uniqueness.

The Effects Of Inulin And Galactooligosaccharides On The Production Of Reuterin By Lactobacillus Reuteri, Micah Dwight Forshee

ELAIA

The microbiome is a dynamic community that can positively and negatively influence host health. Lactobacillus reuteri is a probiotic that has received much attention for its ability to inhibit pathogens such as Salmonella typhimurium, Escherichia coli, and Clostridium difficile. It does so by its unique ability to metabolize glycerol into the antimicrobial compound 3-HPA, which is commonly referred to as reuterin. The ability to secrete reuterin is dependent not only on glycerol availability but also the concentration of glucose. In fact, there appears to be a “goldilocks” ratio between glucose and glycerol as either too much or too little …

Investigating The Toxicity And Accumulation Of 2,4-Dichlorophenoxyacetic Acid (2,4-D) And Glyphosate In Eisenia Fetida, Caitlin Lazurick, Nicole Lidzbarski, Rachel Owings, Jeff Brotherton, Edna Steele

Journal of the South Carolina Academy of Science

Glyphosate, the main ingredient in Roundup^®, is the most widely used herbicide in the world. It is also used in combination with another effective herbicide, 2,4-D, in the formulation called Enlist Duo^®. The EPA approved the use of Enlist Duo^® on certain crops including those genetically modified to be resistant to both herbicides. The predicted significant increase in the use of these herbicides raised concerns from the general public because both compounds have been classified as possibly or probably carcinogenic. Since herbicides are applied directly to vegetation, the safety of organisms that come in contact …
