2020-Current year OA Pubs

Genome browsers have become an intuitive and critical tool to visualize and analyze genomic features and data. Conventional genome browsers display data/annotations on a single reference genome/assembly; there are also genomic alignment viewer/browsers that help users visualize alignment, mismatch, and rearrangement between syntenic regions. However, there is a growing need for a comparative epigenome browser that can display genomic and epigenomic data sets across different species and enable users to compare them between syntenic regions. Here, we present the WashU Comparative Epigenome Browser. It allows users to load functional genomic data sets/annotations mapped to different genomes and display them over …

METHODS: Genotypes from the National Institute on Aging Late-Onset Alzheimer's Disease Family-Based Study and a study of familial Alzheimer's disease in Caribbean Hispanics were used to compute PRS with and without variants in the 2 MB region flanking APOE. PRS was calculated in using clumping/thresholding and Bayesian methods and was assessed for association with Alzheimer's disease and age at onset. Penetrance and recurrence risk for carriers in highest and lowest PRS quintiles were compared separately within APOE-ε4 carriers …

Immunotherapeutic Approach To Reduce Senescent Cells And Alleviate Senescence-Associated Secretory Phenotype In Mice, Niraj Shrestha, Mark Foster, Lynne Marsala, Pamela Wong, Celia C Cubitt, Jennifer A Foltz, Jennifer Tran, Timothy Schappe, Melissa M Berrien-Elliott, Todd A Fehniger, Et Al.

2020-Current year OA Pubs

Accumulation of senescent cells (SNCs) with a senescence-associated secretory phenotype (SASP) has been implicated as a major source of chronic sterile inflammation leading to many age-related pathologies. Herein, we provide evidence that a bifunctional immunotherapeutic, HCW9218, with capabilities of neutralizing TGF-β and stimulating immune cells, can be safely administered systemically to reduce SNCs and alleviate SASP in mice. In the diabetic db/db mouse model, subcutaneous administration of HCW9218 reduced senescent islet β cells and SASP resulting in improved glucose tolerance, insulin resistance, and aging index. In naturally aged mice, subcutaneous administration of HCW9218 durably reduced the level of SNCs and …

The Complement System And Human Autoimmune Diseases, Samantha L Coss, Danlei Zhou, Gilbert T. Chua, Rabheh Abdul Aziz, Robert P. Hoffman, Yee Ling Wu, Stacy P. Ardoin, John P. Atkinson, Chack-Yung Yu

2020-Current year OA Pubs

Genetic deficiencies of early components of the classical complement activation pathway (especially C1q, r, s, and C4) are the strongest monogenic causal factors for the prototypic autoimmune disease systemic lupus erythematosus (SLE), but their prevalence is extremely rare. In contrast, isotype genetic deficiency of C4A and acquired deficiency of C1q by autoantibodies are frequent among patients with SLE. Here we review the genetic basis of complement deficiencies in autoimmune disease, discuss the complex genetic diversity seen in complement C4 and its association with autoimmune disease, provide guidance as to when clinicians should suspect and test for complement deficiencies, and outline …

The Ambiguity Of Probable Cause And Its Contentious Application By Police, Dave Sainte-Luce

College Honors Program

It is well documented how our country’s Criminal Justice System has a history of targeting people of color. A lot of this contention is derived from police officers’ behavior when interacting with individuals, yet officers only act upon the laws and legal policies that grant them authority, including probable cause. My thesis addresses the question, how does the fluid and ambiguous nature of probable cause leave the door open for officers to disproportionately target people of color in the United States? While focusing on vehicle, person, and property searches, I first define probable cause, building an understanding of exactly what …

Analysis Of Genes Responsible For Neuronal Morphological Changes In Down Syndrome Hipsc-Derived Neurons, Juhi Patel

Senior Theses

Down syndrome (DS) is a complex neurodevelopmental disorder caused by the trisomy of chromosome 21. DS is the largest genetic cause of intellectual disability, which occurs in varying severity among affected individuals. It is associated with a variety of developmental and cognitive defects, including reduced brain size, impaired synaptic function, and altered neuronal morphology. A number of genes have been identified to play critical roles in the development and maintenance of neuronal morphology, and alterations in the expression of some of these genes are implicated in the morphological changes observed in DS. Knocking out or altering their expression leads to …

150th Anniversary Gala Dean Address, Angela Onwuachi-Willig

Faculty Scholarship

One hundred fifty years ago tomorrow, eighteen professors and approximately sixty students held the first day of classes at what was then called Boston School of Law. It was 1872. The Civil War had ended less than a decade before. The telephone had not been invented yet. It was a remarkably different time in our nation’s history.

Our law school’s rather humble beginnings did not portend the impressive legacy that it would build over the next 150 years. At the time, the school consisted of only one small lecture hall and an adjacent room for the dean—tight quarters for a …

Diverse Patients’ Attitudes Towards Artificial Intelligence (Ai) In Diagnosis, Christopher Robertson, Andrew Woods, Kelly Bergstrand, Jessica Findley, Cayley Balser, Marvin J. Slepian

Faculty Scholarship

Artificial intelligence (AI) has the potential to improve diagnostic accuracy. Yet people are often reluctant to trust automated systems, and some patient populations may be particularly distrusting. We sought to determine how diverse patient populations feel about the use of AI diagnostic tools, and whether framing and informing the choice affects uptake. To construct and pretest our materials, we conducted structured interviews with a diverse set of actual patients. We then conducted a pre-registered (osf.io/9y26x), randomized, blinded survey experiment in factorial design. A survey firm provided n = 2675 responses, oversampling minoritized populations. Clinical vignettes were randomly manipulated in eight …

The Public Stakes Of Consumer Law: The Environment, The Economy, Health, Disinformation, And Beyond, Rory Van Loo

It also offers a more integrated conceptual and institutional approach to consumer law so that the field can have a better chance of fulfilling its societal potential.

Part I of this Article outlines the importance of consumer law. It maps consumer law’s connections to some of the most pressing societal threats: climate change, public health, inequality, and disinformation. Part II focuses on consumer law’s place in the legal academy and government. Currently, important …

Patents' New Salience, Janet Freilich

Faculty Scholarship

The vast majority of patents do not matter. They are almost never enforced or licensed and, in consequence, are almost always ignored. This is a well-accepted feature of the patent system and has a tremendous impact on patent policy. In particular, while there are many aspects of patent law that are potentially troubling-including grants of unmerited patents, high transaction costs in obtaining necessary patent licenses, and patents' potential to block innovation and hinder economic growth-these problems may be insignificant in practice because patents are under-enforced and routinely infringed without consequence.

This Article argues that technological developments are greatly increasing the …

Extending The Wavelength Response Of Photon-Counting Image Sensors, Kaitlin M. Anagnost

Dartmouth College Ph.D Dissertations

Non-visible imaging is used in a variety of applications, including medical imaging, security, astronomy, light detection and ranging (LiDAR), and more. Typical silicon- based detectors are primarily limited to the visible, ultraviolet, soft x-ray (<10 keV), and short-wave infrared (IR) spectral regimes. To improve the sensor’s quantum efficiency for x-rays, for example, a scintillating layer may be deposited at the cost of decreased spatial resolution. State-of-the-art IR detectors, on the other hand, use HgCdTe, InSb, InP, III-V superlattices, and other materials with metal hybrid or bump bonds in favor of silicon direct-deposit detectors, decreasing yield. Silicon-based detectors with photon conversion layers are presented in this thesis as possible approaches to extend the wavelength response into the x-ray and IR spectral regimes. A photon attenuation layer (PAL) is first described for better x-ray sensitivity to mitigate the quantum efficiency vs. spatial resolution trade-off in scintillators. Next, silicon’s IR response is improved by considering GeSn and various III-V materials for direct deposition on CMOS image sensors. The band structures and detector parameters for these materials on silicon are calculated and compared to find the most favorable IR absorber. The deposition process for the photon conversion layers can cause the pixel’s transfer gate to lose functionality. CMOS image sensors without transfer gates, called 3-T pixels, are used to prevent this problem, but are dominated by kTC noise each time the device is reset. To combat this issue, a reset noise reduction method utilizing a feedback amplifier is correspondingly discussed, with both theoretical and experimental results presented. A novel pixel using an IR absorbing layer for LiDAR applications is proposed next to bring the IR absorbing layer to market. Single photon avalanche diodes (SPADs) are the iii current state-of-the-art detectors for direct time-of-flight applications because of their high speed and superior timing resolution. Quanta Image Sensors (QIS) have smaller pixel pitch and lower power dissipation per event, however. A pixel design with the advantages of each detector is presented and the simulation results are analyzed. Associated readout circuitry using a time-gating approach is also discussed and theoretical proof-of-concept is demonstrated.

Population-Based Estimates Of Children With Congenital Heart Disease And Quantifying Their Burden Of Care, Devin M. Parker

Dartmouth College Ph.D Dissertations

Background. This dissertation examined children with congenital heart disease (CHD) in Colorado (CO) from 2012 to 2019. Specifically, three studies were conducted that investigated state prevalence rates, related comorbidities and geographic factors associated with access and outcomes for children with CHD. Methods. A descriptive, retrospective 8-year analysis of CO All Payer Claims Data (APCD). Children were identified by administrative diagnoses codes (CD-9-CM and ICD-10-CM). The population includes all children with CHD (aged < 18 years on Jan 1, 2012) with a documented CO zip-code and at least one healthcare encounter in CO. Coexisting comorbidities were defined by the Pediatric Chronic Complex Condition (PCCC) and Children with Disabilities (CWD) algorithms. Providers were identified by their National Provider ID (NPI) and categorized by APCD. Geographic access was calculated using a network analysis of the road distance weighted by travel speeds from the geographic centroid of every ZIP code in CO to that of the geocoded provider address. Outcomes were defined by Berenson-Eggers Type of Service (BETOS) codes. Multivariable logistic regression and mixed effect negative binomial regression models were used. Results. The first study found a significantly higher prevalence rate compared to the national average. A total of 1,566,328 children received care in CO from 2012 – …

Pancreatitis, Panniculitis And Polyarthralgia Syndrome: A Rare Complication Of Pancreatic Pathology, Harjinder Singh, Parth Patel, Shamik Parikh, Hassan Zreik, Neil Caliman, Vivek Kak

Internal Medicine Articles

Pancreatitis, panniculitis, and polyarthralgia (PPP) syndrome is a rare complication of chronic pancreatitis and occurs due to leakage of pancreatic enzymes in the systemic vasculature. This enzyme leakage leads to multiple manifestations such as polyarthralgia, panniculitis, and bone necrosis due to tissue autodigestion. The inciting pancreatic pathology may be masked, and the presentation may be due to one of the systemic consequences of enzyme leakage, which can present as a diagnostic challenge for clinicians. Here we present a patient who presented with nodular lesions and bone necrosis, and was found to have PPP syndrome. Therefore, a proper understanding of pathophysiology …

Splenic Artery Embolism In Liver Transplant Patients: A Single-Center Experience, Mark S. Obri, Wasih Kamran, M. Ramzi Almajed, Daniel Eid, Deepak Venkat

Internal Medicine Articles

BACKGROUND: Hypersplenism, portal hypertension, and ascites have been seen after liver transplants. Patients are usually treated medically with refractory patients potentially undergoing splenectomy. Splenic artery embolism (SAE) is an alternative that can be performed to limit the surgical intervention that may have the benefit of improving portal hypertension. Few studies have studied the effect on main portal vein (MPV) velocities and hepatic artery resistive indices (HARIs) which may be beneficial as markers of portal hypertension.

PURPOSE: This study aims to evaluate the efficacy and safety of interventional radiology (IR)-guided SAE for the management of portal hypertension in patients who have …

Its clinical manifestations are varied and can result in a mix of hepatic and neuropsychiatric symptoms. We present the case of a 26-year-old female with a past medical history of alcohol use who presented with right upper quadrant abdominal pain with associated vomiting, jaundice, and fatigue. She was found to have signs and symptoms of decompensated cirrhosis and was initially concerned about superimposed alcoholic hepatitis. With low ceruloplasmin and alkaline phosphatase, the suspicion for WD remained, and …

An Internist's Approach To A Case Of Negative Pressure Pulmonary Edema: A Rare Cause Of Noncardiogenic Pulmonary Edema, Renato Cerna-Viacava, M. Ramzi Almajed, Julio Pinto Corrales

Internal Medicine Articles

Negative-pressure pulmonary edema (NPPE) is a rare cause of noncardiogenic pulmonary edema, which usually presents postoperatively. Its pathophysiology is mostly described as a profound negative intrathoracic pressure caused by an airway obstruction such as laryngospasm, which may occur during extubation. But, there are other hypotheses about it, such as catecholamines release causing an elevated hydrostatic pressure in the cardiopulmonary circuit and, consequently, a major capillary leak to the interstitium. Its natural course varies, from prompt recovery to intensive care unit escalation and prolonged mechanical ventilation. Although anesthesiologists often detect this condition, this case's objective is to bring awareness of this …

Aspirin And Immunotherapy: A Faustian Bargain?

Faculty, Staff and Students Publications

Fibrinogen-like protein 1 (FGL1) has been associated with improved survival in hepatocellular carcinoma (HCC). However, recent evidence suggests that FGL1 may bind to surface receptors on lymphocytes and induce immune senescence. In this issue of the JCI, Lin and co-authors show that FGL1 may be acetylated by aspirin and targeted for degradation, which is associated with increased antitumor immunity and improved survival. Similar findings were obtained with inhibitors of sirtuin 2 (SIRT2), a histone deacetylase. These findings expand our current understanding of the role of FGL1 in cancer and provide an impetus for the evaluation of alternative immunotherapy combinations in …
