Optimization Of Tyrosine Hydroxylase Antibody For Immunohistochemistry Fluorescence Detection In Zebrafish (Danio Rerio), Madison Thurber
Theses/Capstones/Creative Projects
Dopamine is an important neurotransmitter produced through the catecholamine synthesis pathway that affects brain activity. Unregulated dopamine levels can lead to various diseases such as Parkinson’s Disease or attention deficit hyperactivity disorder (ADHD). Optimization of an immunohistochemistry protocol will allow for the quantification of tyrosine hydroxylase antibody, which indirectly allows for dopamine quantification in dopaminergic regions within the brain. However, the antibody concentration to give the optimal signal-to-noise ratio in IHC varies across studies. Through this experiment, I determined the concentration of tyrosine hydroxylase (TyrH) antibody for immunohistochemistry that gave the best signal-to-background noise ratio within several known dopaminergic regions …

The Role Of Extracellular Vesicles In Immunomodulation During Bovine Pregnancy, 2024 Utah State University
The Role Of Extracellular Vesicles In Immunomodulation During Bovine Pregnancy, Amber E. Thornton
All Graduate Theses and Dissertations, Fall 2023 to Present
During pregnancy, the maternal immune system must be altered to protect the partially non-self fetus from attack. Our previous studies show an inflammatory response in the uterus of cows carrying somatic cell nuclear transfer (SCNT), commonly known as cloned, pregnancies due to abnormalities in proteins expressed by placental trophoblast cells. Between 30 and 90 days the rate of pregnancy loss is 50-100% for SCNT compared to 2-10% for artificial insemination (AI) pregnancies. Abnormal communication between the maternal and fetal systems during placentation is a major cause of this loss. The trafficking of extracellular vesicles (EVs), membrane-bound cargo carriers, potentially represents …

The Effects Of Ammonia On The Functionality Of Bovine Granulosa Cells, 2024 Utah State University
The Effects Of Ammonia On The Functionality Of Bovine Granulosa Cells, Micah Henrie
All Graduate Theses and Dissertations, Fall 2023 to Present
It is common practice in the livestock animal production industries to feed high levels of protein to maximize the yield of each animal in production. However, diets high in protein can cause decreased reproductive success within these animals. The causes behind this decrease are not fully understood. Increased dietary protein leads to increased levels of both ammonia and urea in the blood of the animal. These increased metabolite levels may be a possible explanation for the decline in reproductive success. The goal of this study is to identify how various levels of ammonia affect the function of bovine granulosa cells …
The Effects Of Aboveground Herbivory On Root Traits And Root Decomposition, 2024 Utah State University
The Effects Of Aboveground Herbivory On Root Traits And Root Decomposition, Emily A. Chavez
All Graduate Theses and Dissertations, Fall 2023 to Present
Soil holds more carbon (C) than the Earth's atmosphere and vegetation combined. Soil loses carbon through soil respiration and releases CO2 from the soil. The soil respiration rate can vary based on the chemistry of the plant litter inputs and physical factors, such as soil temperature and nutrient content. In Alaska's Yukon-Kuskokwim (YK) Delta, grazing by geese affects the chemistry of plants and the soil's physical qualities, thus altering the rate of soil respiration. Although we know that goose herbivory leads to changes in the rate of soil respiration, we know very little about how goose herbivory affects the …
