Oxytocin Receptor Binding In The Substantia Nigra In Schizophrenia, Ariel Snowden Apr 2023

Oxytocin Receptor Binding In The Substantia Nigra In Schizophrenia, Ariel Snowden

Student Research Symposium

Schizophrenia is a chronic, psychiatric disorder characterized by hallucinations, delusions, cognitive deficits, and social cognitive impairments. Although antipsychotic drugs are typically effective in treating psychotic symptoms in schizophrenia, the social cognitive symptoms often persist. As social cognitive functioning is predictive of successful life outcomes in schizophrenia, there is a critical need to determine the biological basis of social cognitive impairments. Due to its ability to affect social behaviors in animals and humans, the oxytocin (OXT) system has become a therapeutic target of interest for schizophrenia. Although several studies examine the OXT system in schizophrenia in the periphery, it is currently …

Cycloaddition Of Aryldiazoacetates With Terminal Alkynes And Nitriles Via A Bioinspired Cobalt Complex, Liming Tan Apr 2023

Cycloaddition Of Aryldiazoacetates With Terminal Alkynes And Nitriles Via A Bioinspired Cobalt Complex, Liming Tan

Student Research Symposium

In this study, we present a novel method for the efficient cycloaddition of aryl diazoacetates with both terminal alkynes and nitriles, employing a bioinspired cobalt complex as a catalyst. Our findings indicate that terminal alkynes react with aryl diazoacetates to yield a cyclopropenation product through a 2+1 cycloaddition reaction. Meanwhile, nitriles react with aryl diazoacetates to produce an oxazole product via a 2+3 cycloaddition reaction. These results have significant implications for the development of new synthetic routes towards cyclopropenation and oxazole compounds.

Glycosylation Of Anti-Tb Agent Chlorflavonin For Combating Mycobacterium Tuberculosis, Jie Ren Apr 2023

Glycosylation Of Anti-Tb Agent Chlorflavonin For Combating Mycobacterium Tuberculosis, Jie Ren

Student Research Symposium

More than two billion people were infected by the bacterial pathogen Mycobacterium tuberculosis (Mtb) in 2020. However, during the past 50 years, the first-line (isoniazid, delamanid, and rifampicin) and second-line (capreomycin, streptomycin, and cycloserine) therapies have remained unchanged with disadvantages such as long treatment periods and severe side effects. The slow development of anti-TB drugs cannot combat the fast development of drug resistant M. tuberculosis strains from multidrug-resistant (MDR) into extensively drug resistant (XDR), which further hinders the World Health Organization’s goal to end the global TB pandemic by the year 2035. Flavonoids are a type of natural product with …

Treating Yellow Fever Virus With The Antiviral Bdaa And Effects On The Immune Response In An Animal Model, Abbie Weight Apr 2023

Treating Yellow Fever Virus With The Antiviral Bdaa And Effects On The Immune Response In An Animal Model, Abbie Weight

Student Research Symposium

Yellow fever virus (YFV) is a mosquito-borne virus with a considerable disease burden in South America and Africa and no approved antivirals. BDAA is an experimental antiviral for YFV which inhibits the viral protein NS4B and is effective against YFV in cell culture and a hamster model. Along with directly inhibiting virus replication, treating YFV-infected cells with BDAA increases the detection and response to foreign RNA by the host cell by releasing YFV replication intermediates into the cytoplasm. While this has been shown in cell culture, it is important to understand if this immune effect is relevant to BDAA’s efficacy …

Catchment Protections Enhance River Resilience To Water Quality Perturbations, Allyson Marrs Apr 2023

Catchment Protections Enhance River Resilience To Water Quality Perturbations, Allyson Marrs

Student Research Symposium

Around 40% of rivers in the United States have been increasing in salinity in recent decades. This salinization is caused by natural and anthropogenic processes, such as applying salts to roads for deicing purposes. Rapid increases in salinity in freshwater streams can have negative impacts on drinking water, infrastructure, and biodiversity. However, catchment protections may offer resilience to water quality degradation. Using a weighted regression on time, discharge, and season, we analyzed long-term trends in specific conductance in the Yellowstone River at Corwin Springs. The majority of the Yellowstone River upstream of this site lies on federally protected lands with …

Specifying An Identified Lncrnas Modulation In Cellular Processes During Early Embryonic Development Of Nicotiana Tabacum Seedlings, Heather Garrett, Elena Foust, Logan Robinson

Undergraduate Research Competition

Multiple forms of RNA exist in cells. The most common forms of RNA include tRNA, rRNA, and mRNA. LncRNAs are proposed to have multiple functions during seed development including gene silencing, organogenesis, and other molecular processes. LncRNAs are unknown or poorly understood because their importance has been questioned throughout early research. However, the lncRNA NTAB_LNC014148.1 is presumed to function in seed development of Nicotiana tabacum based on global gene expression studies. Bioinformatics analyses predicted that lncRNA NTAB_LNC014148.1 binds to at least two gene regions during embryonic development (gene regions Nitab4.5_0001672g0150.1 and Nitab4.5_0001972g0020.1). These two gene regions encode an Arf GTPase …

Evolutionary Analysis Of Plastic-Degrading Enzyme Petase Found In The Endophytic Microbiome Of Marine Viridiplantae For Phytoremediation, Marissa Mazariego

Undergraduate Research Competition

In 2016, a bacteria found outside a recycling facility in Japan was discovered to decompose and metabolize polyethylene terephthalate (PET). Ideonella sakaiensis exhibited catabolic activity by binding to the surface of the products and delivering PETase enzymes to degrade plastic into its original structural components. PET is a clear plastic designed for single-use packaging. Despite the claim that PET plastics are 100% recyclable, only 31% of PETs are recycled. PETs do not decompose for up to 450 years in disposal facilities, resulting in the clogging of natural landscapes with litter and phthalate toxins. It is suggested that the selective pressure …

The Salinity Of The Great Salt Lake And Its Deep Brine Layer, Madeline F. Merck, David G. Tarboton

Publications

The Great Salt Lake is a highly saline terminal lake with considerable fluctuations in water surface elevation and salinity. The lake is divided into two arms by a railroad causeway. River inflows enter the larger south arm, while the north arm only receives minimal surface runoff. Evaporation from both arms and limited exchange of water and salt through causeway openings result in complex water and salinity processes in the lake. The north arm is typically homogeneous and close to saturation. The south arm is typically stratified with periodic occurrences of a deep brine layer. This paper analyzes the lake’s long-term …
