Faculty, Staff and Students Publications

BACKGROUND: Extrauterine growth restriction is a common complication of preterm birth. Leucine (Leu) is an agonist for the mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) signaling pathway that regulates translation initiation and protein synthesis in skeletal muscle. Previously, we showed that intermittent intravenous pulses of Leu to neonatal pigs born at term receiving continuous enteral nutrition increases muscle protein synthesis and lean mass accretion. Our objective was to determine the impact of intermittent intravenous pulses of Leu on muscle protein anabolism in preterm neonatal pigs administered continuous parenteral nutrition.

METHODS: Following preterm delivery (on day 105 of 115 gestation), …

Faculty, Staff and Students Publications

BACKGROUND: Elevated oxidative stress (OxS), mitochondrial dysfunction, and hallmarks of aging are identified as key contributors to aging, but improving/reversing these defects in older adults (OA) is challenging. In prior studies, we identified that deficiency of the intracellular antioxidant glutathione (GSH) could play a role and reported that supplementing GlyNAC (combination of glycine and N-acetylcysteine [NAC]) in aged mice improved GSH deficiency, OxS, mitochondrial fatty-acid oxidation (MFO), and insulin resistance (IR). To test whether GlyNAC supplementation in OA could improve GSH deficiency, OxS, mitochondrial dysfunction, IR, physical function, and aging hallmarks, we conducted a placebo-controlled randomized clinical trial.

METHODS: Twenty-four …

Multi-Task Learning For Post-Transplant Cause Of Death Analysis: A Case Study On Liver Transplant, Sirui Ding, Qiaoyu Tan, Chia-Yuan Chang, Na Zou, Kai Zhang, Nathan R Hoot, Xiaoqian Jiang, Xia Hu

Faculty, Staff and Student Publications

Organ transplant is the essential treatment method for some end-stage diseases, such as liver failure. Analyzing the post-transplant cause of death (CoD) after organ transplant provides a powerful tool for clinical decision making, including personalized treatment and organ allocation. However, traditional methods like Model for End-stage Liver Disease (MELD) score and conventional machine learning (ML) methods are limited in CoD analysis due to two major data and model-related challenges. To address this, we propose a novel framework called CoD-MTL leveraging multi-task learning to model the semantic relationships between various CoD prediction tasks jointly. Specifically, we develop a novel tree distillation …

Wnt Signaling In Liver Regeneration, Disease, And Cancer, Gengyi Zou, Jae-Il Park

Faculty, Staff and Student Publications

The liver exhibits the highest recovery rate from acute injuries. However, in chronic liver disease, the long-term loss of hepatocytes often leads to adverse consequences such as fibrosis, cirrhosis, and liver cancer. The Wnt signaling plays a pivotal role in both liver regeneration and tumorigenesis. Therefore, manipulating the Wnt signaling has become an attractive approach to treating liver disease, including cancer. Nonetheless, given the crucial roles of Wnt signaling in physiological processes, blocking Wnt signaling can also cause several adverse effects. Recent studies have identified cancer-specific regulators of Wnt signaling, which would overcome the limitation of Wnt signaling target approaches. …

Interlink Between The Gut Microbiota And Inflammation In The Context Of Oxidative Stress In Alzheimer’S Disease Progression, Tushar K Das, Bhanu P Ganesh

Faculty, Staff and Student Publications

The microbiota-gut-brain axis is an important pathway of communication and may dynamically contribute to Alzheimer's disease (AD) pathogenesis. Pathological commensal gut microbiota alterations, termed as dysbiosis, can influence intestinal permeability and break the blood-brain barrier which may trigger AD pathogenesis via redox signaling, neuronal, immune, and metabolic pathways. Dysbiosis increases the oxidative stress. Oxidants affect the innate immune system through recognizing microbial-derived pathogens by Toll-like receptors and initiating the inflammatory process. Most of the gut microbiome research work highlights the relationship between the gut microbiota and AD, but the contributory connection between precise bacteria and brain dysfunction in AD pathology …

Faculty, Staff and Student Publications

BACKGROUND: Methylene blue (MB) is used endoscopically to demarcate tumors and as a photosensitizer in photodynamic therapy (PDT). However, there are few in vivo studies about its toxicity in healthy stomach tissue. We performed sequential in vitro and in vivo analyses of MB-induced phototoxicity.

METHODS: We performed in vitro experiments using the AGS human gastric cancer cell line treated with light-emitting diode (LED) irradiation (3.6 J/cm

RESULTS: In vitro, increased concentrations of MB led to higher TUNEL scores. However, cell viability was significantly lower after MB plus LED irradiation than after treatment with MB alone (P < 0.001). In vivo, the TUNEL score was highest immediately after treatment with 0.1% or 0.5% MB plus light irradiation, and the score was significantly higher in the LED illumination plus MB group than in the control group (P < 0.05). The elevated TUNEL score was maintained for 3 days in the MB plus light irradiation group but returned to normal levels on day 10.

CONCLUSIONS: : Endoscopic light …

The Genetic Landscape And Clinical Implication Of Pediatric Moyamoya Angiopathy In An International Cohort, Yan-Hao Wei, Ren-Tang Bi, Yan-Mei Qiu, Chun-Lin Zhang, Jian-Zhuang Li, Ya-Nan Li, Bo Hu

Faculty, Staff and Student Publications

Ischemic stroke is a highly complex systemic disease characterized by intricate interactions between the brain and gastrointestinal tract. While our current understanding of these interactions primarily stems from experimental models, their relevance to human stroke outcomes is of considerable interest. After stroke, bidirectional communication between the brain and gastrointestinal tract initiates changes in the gastrointestinal microenvironment. These changes involve the activation of gastrointestinal immunity, disruption of the gastrointestinal barrier, and alterations in gastrointestinal microbiota. Importantly, experimental evidence suggests that these alterations facilitate the migration of gastrointestinal immune cells and cytokines across the damaged blood-brain barrier, ultimately infiltrating the ischemic brain. …

How Widespread And Convenient H Pylori Susceptibility Testing Will Result In Pharmacological Opportunities, Theodore Rokkas, David Y Graham

Faculty, Staff and Students Publications

Introduction:

Until recently antimicrobial therapy for Helicobacter pylori infections was almost universally empirical and based on a combination of expert opinion and local effectiveness. However, the average cure rates rarely achieved more than 80%. The new requirement that all therapeutic regimens reliably achieve high cure rates, the introduction of potassium competitive acid blockers and the availability of susceptibility testing many pharmacological opportunities particularly since all current therapies will require optimization. The ability to rapidly and inexpensively obtain H. pylori susceptibility data using stool samples makes obtaining susceptibility data practical and allows using susceptibility-based therapy routinely for both treatment naïve patient …

Cholestasis Impairs Gut Microbiota Development And Bile Salt Hydrolase Activity In Preterm Neonates, Lauren E Lynch, Amy B Hair, Krishnakant G Soni, Heeju Yang, Laura A Gollins, Monica Narvaez-Rivas, Kenneth D R Setchell, Geoffrey A Preidis

Faculty, Staff and Students Publications

Cholestasis refers to impaired bile flow from the liver to the intestine. In neonates, cholestasis causes poor growth and may progress to liver failure and death. Normal bile flow requires an intact liver-gut-microbiome axis, whereby liver-derived primary bile acids are transformed into secondary bile acids. Microbial bile salt hydrolase (BSH) enzymes are responsible for the first step, deconjugating glycine- and taurine-conjugated primary bile acids. Cholestatic neonates often are treated with the potent choleretic bile acid ursodeoxycholic acid (UDCA), although interactions between UDCA, gut microbes, and other bile acids are poorly understood. To gain insight into how the liver-gut-microbiome axis develops …

A Systematic Review Of Associations Between Gut Microbiota Composition And Growth Failure In Preterm Neonates, Larissa L Neves, Amy B Hair, Geoffrey A Preidis

Faculty, Staff and Students Publications

Growth failure is among the most prevalent and devastating consequences of prematurity. Up to half of all extremely preterm neonates struggle to grow despite modern nutrition practices. Although elegant preclinical models suggest causal roles for the gut microbiome, these insights have not yet translated into biomarkers that identify at-risk neonates or therapies that prevent or treat growth failure. This systematic review aims to identify features of the neonatal gut microbiota that are positively or negatively associated with early postnatal growth. We identified 860 articles, of which 14 were eligible for inclusion. No two studies used the same definitions of growth, …

Using the United Network for Organ Sharing registry, we evaluated waitlist and post-LT survival in all adult patients listed for HH without concomitant liver disease from 2003 to 2019. Post-LT survival for HH was compared with a propensity-matched (recipient and donor factors) cohort of recipients with chronic liver disease (CLD). From 2003 to 2019, 862 patients with HH were listed for LT, of which 55.6% ( n = 479) patients underwent …

How I Approach Leishmaniasis: Diagnosis And Treatment In The United States, Tara E Ness, Rachel Martin-Blais, Jill E Weatherhead

Faculty, Staff and Students Publications

Leishmaniasis is a vector-borne disease caused by over 20 species of obligate intracellular protozoa belonging to the genus Leishmania. Leishmaniasis has a global distribution, including in the United States, and can cause a spectrum of clinical syndromes, including cutaneous, mucosal, and visceral diseases depending on host factors and the infecting Leishmania spp. Accurate diagnosis, including Leishmania species identification, is an important step to guide the most appropriate therapeutic intervention. Antileishmanial therapy is dependent on the Leishmania spp. identified, the clinical syndrome, and the child's immune system. However, many treatment regimens for children have been extrapolated from adult clinical trials, which …
