• This is a report of a patient with severe sarcopenia and ESLD who was provided enteral nutrition using a Dobhoff tube (DHT) pre-liver transplant resulting in successful bridging to transplant.

Primary Seronegative But Molecularly Evident Hepadnaviral Infection Engages Liver And Induces Hepatocarcinoma In The Woodchuck Model Of Hepatitis B, Ranjit Chauhan

School of Medicine

Hepadnavirus at very low doses establishes in woodchucks asymptomatic, serologically undetectable but molecularly evident persistent infection. This primary occult infection (POI) preferentially engages the immune system and initiates virus-specific T cell response in the absence of antiviral antibody induction. The current study aimed to determine whether POI with time may culminate in serologically identifiable infection and hepatitis, and what are, if any, its pathological consequences. Juvenile woodchucks were intravenously injected with inocula containing 10 or 100 virions of woodchuck hepatitis virus (WHV) to induce POI and followed for life or up to 5.5 years thereafter. All 10 animals established molecularly …

The Prevention Of Inflammatory-Related Liver Damage By Tamoxifen In Rats Given Fish Oil, Renae Haycraft

Journal of Undergraduate Research at Minnesota State University, Mankato

The focus of this research was to decrease inflammatory-related liver damage from tamoxifen in rats by adding fish oil to the diet. Tamoxifen causes a significant increase in inflammation of the liver. Inflammation increases with the production of prostaglandins by a metabolic pathway involving arachidonic acid. The metabolism of tamoxifen by the enzyme cytochrome P450 leads to an increase in the production of prostaglandins. The increased inflammation is proportional to lipid accumulation and ultimately lipid peroxidation in the liver. Resulting damage in humans includes hepatic steatosis (fatty liver), nonalcoholic steatohepatitis (NASH), and cirrhosis. Fish oils rich in omega-3 fatty acids, …

Vascular Architecture Of The Liver In Shr And Wky Rats, Charalette Mathwig, Kenneth Willaert

Journal of Undergraduate Research at Minnesota State University, Mankato

The liver is a highly complex vascular organ containing an intricate network of arteries, arterioles, portal veins, veins, venules, and capillaries. This complex network could change in situations related to vascular disease such as hypertension. We examined the vasculature in rat livers by scanning electron microscopy. The tissue was prepared by perfusing either Mercox resin or polyurethane resin into the vasculature. Once the resin polymerized, each liver was placed in concentrated potassium hydroxide to corrode the tissue from the vascular casts. The casts were critical point dried, sputter coated with gold-palladium, and viewed by scanning electron microscopy. Examination of the …

Appropriate Development Of The Liver Treg Compartment Is Modulated By The Microbiota And Requires Tgf-Β And Myd88, Ann Maria, Kathryn A. English, James D. Gorham

Dartmouth Scholarship

Neither the early postnatal development of the liver Treg compartment nor the factors that regulate its development has been characterized. We compared the early developmental patterns of Treg cell accumulation in murine liver, thymus, and spleen. A FoxP3EGFP reporter mouse was employed to identify Treg cells. Mononuclear cells were isolated from organs postnatally, stained for CD4, and examined by flow cytometry to enumerate FoxP3+CD4hi cells. To assess roles for TGF-��1, MyD88, and TLR2, gene specific knockout pups were generated from heterozygous breeders. To test the role of commensal bacteria, pregnant dams were administered antibiotics during gestation and after parturition.The pattern …

Localization And Expression Level Of Vascular Endothelial Growth Factor After Partial Hepatectomy Of Wky Rats, Adam Kronebusch, Tyler Koonst

Undergraduate Research Symposium

Inflammation and fibrosis are indicative of liver regeneration following injury and chronic liver diseases, such as cirrhosis and hepatocellular carcinoma. The formation of new vasculature via the process of angiogenesis is vital to the pathological progression of liver regeneration and these diseases. Thus, inhibiting the process of angiogenesis could have the potential to stop or slow the progression of chronic liver diseases. Vascular endothelial growth factor (VEGF) is the most potent and specific growth factor for initiating the process of angiogenesis, making it a prime target to inhibit angiogenesis. Bevacizumab is an antibody that binds to VEGF, inhibiting it from …

Primary And Secondary Prevention Of Hepatitis C Virus Among Rural Appalachian People Who Use Drugs, Dustin B. Stephens

Theses and Dissertations--Clinical and Translational Science

Hepatitis C virus (HCV) remains a major cause of morbidity and mortality worldwide, with 3% of the global population chronically infected. Clinical impacts in the United States are projected to increase for two decades, and mortality attributed to HCV now exceeds HIV. Injection drug use (IDU) is the most common route of transmission in the developed world. Advances in treatment offer hope of mitigating HCV impacts, but substantial barriers obstruct people who inject drugs (PWID) from receiving care, particularly in medically underserved regions including Central Appalachia. This study assessed IDU paraphernalia sharing longitudinally over 24 months in a sample of …

Analysis Of The Role Of Astrocyte Elevated Gene-1 In Normal Liver Physiology And In The Onset And Progression Of Hepatocellular Carcinoma, Chadia L. Robertson

Theses and Dissertations

First identified over a decade ago, Astrocyte Elevated Gene-1 (AEG-1) has been studied extensively due to early reports of its overexpression in various cancer cell lines. Research groups all over the globe including our own have since identified AEG-1 overexpression in cancers of diverse lineages including cancers of the liver, colon, skin, prostate, breast, lung, esophagus, neurons and neuronal glia as compared to matched normal tissue. A comprehensive and convincing body of data currently points to AEG-1 as an essential component, critical to the progression and perhaps onset of cancer. AEG-1 is a potent activator of multiple pro-tumorigenic signal transduction …

Increasing Physical Activity In Post Liver Transplant Patients, Jennifer Lynn Serotta

UNF Graduate Theses and Dissertations

The purpose of this quality improvement project was to increase physical activity among postoperative adult liver transplant patients, improve documentation of daily activity, and ultimately influence quality of life (QOL). Quality of life has been shown to improve dramatically after liver transplant, as patients enter transplant severely debilitated with limitations on their physical activity which carry over following transplant. The literature supports that liver transplant patients should engage in physical activity which may improve QOL. Thirteen liver transplant patients were recruited within the seven days of their post-operative hospitalization. Twelve patients consented, were educated about the benefits of walking, given …
