Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes
Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes
Electronic Theses and Dissertations
Opioid use disorder (OUD) impacts 5.6 million people in the US. Buprenorphine (BUP) is a commonly prescribed opioid medication used to treat OUD, including in pregnant women. However, opioid use during pregnancy is associated with poorer infant outcomes including reduced fetal growth, neurodevelopmental deficits, and neonatal opioid withdrawal syndrome (NOWS). Recent clinical data suggests that providing mothers with a lower dose of BUP may result in fewer negative outcomes in infants. Here, a preclinical rodent model of low-dose perinatal BUP exposure was used to study offspring health outcomes in the neonate, juvenile, and adolescent offspring. Dams were given clinically relevant …

Cannabinoids And Retinal Fibrotic Disorders., Lucy June Sloan
Electronic Theses and Dissertations
Retinal fibrosis is detrimental to vision. Retinal pigment epithelial (RPE) cells contribute to several retinal fibrotic diseases. Upon exposure to TGF-β, a key fibrotic cytokine, RPE cells trans-differentiate to myofibroblasts marked by the integration of α-SMA fibers into F-actin stress fibers, which confer strong contractility. Myofibroblasts produce and contract the collagen-rich fibrotic scar and disrupt retinal architecture. In this study, we investigated the in vitro effects of the putative endocannabinoid compound N-oleoyl dopamine (OLDA) on TGF-β2 induced porcine RPE cell contraction and α-SMA expression. Using an in vitro collagen matrix contraction assay, we found that OLDA inhibited TGF-β2 induced contraction …

Discovery Of Distinct Mechanisms Underlying The Relationship Between Drug Taking And Predisposing Behaviors, Tyler A. Roy
Electronic Theses and Dissertations
Drug addiction is a heritable disease characterized by compulsive drug use. The biological mechanisms driving addiction remain largely unknown.1 Previous studies show shared genetic mechanisms underlying addiction risk phenotypes such as anxiety, depression, and novelty/sensation seeking.2,3 Therefore, high-throughput behavioral screening of these traits in single gene knockout mice can allow for the rapid detection of addiction risk candidate genes and mechanisms. Many of these traits are represented in the Knock-Out Mouse Program (KOMP) phenotyping pipeline. Of the initial two hundred twenty-one strains screened in this program, we tested nineteen phenodeviant knock-out mouse strains with C57BL/6NJ controls (N = …
The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
The Potential For Dickeya Dianthicola To Be Vectored By Two Common Insect Pests Of Potatoes, Jonas K. Insinga
Electronic Theses and Dissertations
Dickeya dianthicola (Samson) causing blackleg and soft rot was first detected in potatoes grown in Maine in 2014. Previous work has suggested that insects, particularly aphids, may be able to vector bacteria in this genus between plants, but no conclusive work has been done to confirm this theory. In order to determine whether insect-mediated transmission is likely to occur in potato fields, two model potato pests common in Maine were used: the Colorado potato beetle (Leptinotarsa decimlineata Say) and the green peach aphids (Myzus persicae Sulzer). Olfactometry and recruitment experiments evaluated if either insect discriminates between infected and …
Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows
Electronic Theses and Dissertations
Adipose tissue can be characterized as either being a white (energy storing) depot or a brown (energy expending) depot and both have been found to contain dense networks of neural innervation. This adipose nerve supply regulates numerous metabolic functions and likely plays an important role in the function of adipose blood vessels. Recently our lab has shown in the C57BL/6 mouse model that peripheral neuropathy, or the dying back and dysfunction of the nerves in the superficial tissues such as the skin, can extend into the subcutaneous adipose tissue in conditions commonly associated with the neuropathic phenotype (i.e. diabetes, obesity, …
Effects Of Acute Sepsis On Renal Structure And Sympathetic Innervation In Mice, Tuqa Alkhateeb
Effects Of Acute Sepsis On Renal Structure And Sympathetic Innervation In Mice, Tuqa Alkhateeb
Electronic Theses and Dissertations
Sympathetic nerves are important for renal physiology and sepsis pathophysiology. A recent study showed sprouting of sympathetic nerves in spleen of septic mice. This study was done to test if renal sprouting of sympathetic nerves also happens and to investigate renal morphology in septic mice. Cecal ligation and puncture (CLP) was used to induce sepsis and kidneys were removed for evaluation. Bowman’s space was diminished with cortical bubble cells present suggestive of acute renal pathology, however, renal function was unchanged. Acute sepsis did not affect either renal sympathetic innervation or non-neuronal cholinergic cells. Mouse kidneys had more epinephrine (EPI) than …
An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings
An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings
Electronic Theses and Dissertations
Cancer patients treated with adjuvant chemotherapy often experience cognitive decline following treatment. This phenomenon, often dubbed “chemo brain” or “chemo fog” is usually temporary, but for a subset of survivors, these cognitive impairments can be long-lasting (>10 years) and negatively affect patients’ quality of life, career performance, and social fulfillment. While it is unclear what neurobiological mechanisms underlie chemotherapy related cognitive impairment, the majority of the animal literature has focused on adult neurogenesis. One process important for neurogenesis is the proliferation of new neurons within the dentate gyrus of the hippocampus. It is evident that many chemotherapy agents can …
