Enabling Cross-Modality Translation Between Single-Cell Rna-Seq And Single-Cell Atac-Seq Through Web-Based Portal, Zhen Lyu, Sabin Dahal, Shuai Zeng, Juexin Wang, Dong Xu, Trupti Joshi

Biomedical Sciences

In recent years, there has been a growing interest in profiling multiomic modalities within individual cells simultaneously. One such example is integrating combined single-cell RNA sequencing (scRNA-seq) data and single-cell transposase-accessible chromatin sequencing (scATAC-seq) data. Integrated analysis of diverse modalities has helped researchers make more accurate predictions and gain a more comprehensive understanding than with single-modality analysis. However, generating such multimodal data is technically challenging and expensive, leading to limited availability of single-cell co-assay data. Here, we propose a model for cross-modal prediction between the transcriptome and chromatin profiles in single cells. Our model is based on a deep neural …

Association Of Hiv Status And Other Minoritized Identities With Psychiatric Diagnoses Among Transgender And Gender Diverse Individuals In The All Of Us Research Program, Fanghui Shi

Theses and Dissertations

Background: Transgender and gender diverse (TGD) people, whose gender identities or expressions differ from the sex assigned at birth, are disproportionately affected by adverse health outcomes, including various psychiatric diagnoses such as depression, anxiety, stress, and substance use disorders. The Gender Minority Stress Model emphasizes that TGD people face both proximal stressors at a personal/individual level (e.g., internalized stigma) and distal stressors at a societal level (e.g., discrimination) due to their minority status, which largely contributes to their increased risk of psychiatric diagnoses. Despite these health disparities, there is a paucity of gender identity data collected in large population-based health …

Precision Deuteration And Hydrofunctionalization Of Aryl Alkynes And Alkenes, Samantha E. Sloane Jul 2024

Precision Deuteration And Hydrofunctionalization Of Aryl Alkynes And Alkenes, Samantha E. Sloane

Dissertations (1934 -)

The similar nature of the hydrogen atom to its isotope, deuterium, allows for the simple exchange of hydrogen atoms for deuterium atoms in drug molecules to alter the absorption, distribution, metabolism, and excretion properties. Installing the deuterium functionality into a specific site in the molecule is essential. Selective hydrofunctionalization reactions of alkynes and alkenes using the highly reactive catalytic Cu–H species have been well developed, and synthetic organic chemistry methods to selectively incorporate one or two deuterium atoms into the benzylic site of organic compounds, a key metabolic position, are elusive. A Cu–H catalytic approach offers selectivity and reactivity to …


Mechanisms Of Fatigability In Individuals With Prediabetes And The Effect Of Dietary Nitrate Supplementation, Blaine Evan Arney Jul 2024

Mechanisms Of Fatigability In Individuals With Prediabetes And The Effect Of Dietary Nitrate Supplementation, Blaine Evan Arney

Dissertations (1934 -)

Prediabetes is characterized as elevated blood glucose levels below the clinical threshold for type 2 diabetes. Previous research identified an increased fatigability (exercise-induced reduction in limb force or power) of the lower limb muscles in individuals with prediabetes which can impair physical function and lead to reduced physical activity. The mechanisms of fatigability in people with prediabetes are not known but are likely related to suggested vascular dysfunction in prediabetes. An important healthcare goal is to determine effective treatments to offset the increased fatigability in people with prediabetes to improve daily function. The purpose of this dissertation was to determine …

A Global Perspective On The Treatment And Maintenance Of Mature Skin Using Gentle Cleansers And Moisturizers, Joachim Fluhr, Andrew Alexis, Anneke Andriessen, Olga Barrios, Peter Bjerring, Peter Foley, Michael Gold, Hashim Kaderbhai, Chengfeng Zhang

Internal Medicine, East Africa

Xerosis is highly prevalent in the population aged over 50 years and substantially impacts quality of life due to the associated stigma, related pruritus, and potential sequelae. We propose that the term mature xerosis be used for subjects over 50 who suffer from age-related xerosis and replace senile xerosis to describe the phenomenon. The etiology of xerosis depends on genetic and environmental factors that affect stratum corneum hydration and skin barrier function. Skincare to restore barrier function is essential in xerosis treatment and is relevant for maintaining and preventing its progression. Many moisturizers and cleansers are available for xerosis; however, …

Nonlocal Frameworks For Nonlinear Conservation Laws And Advection-Diffusion Processes, Anh Thuong Vo Jul 2024

Nonlocal Frameworks For Nonlinear Conservation Laws And Advection-Diffusion Processes, Anh Thuong Vo

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Conservation laws are fundamental principles that play an important role in modeling various phenomena in physics, chemistry, and biology. However, their limitations, such as the development of shocks despite smooth initial conditions, are well known. The nonlocal model framework can be used to overcome these challenges. Nonlocal frameworks utilize integral operators that mimic differential operators but also incorporate long-range interactions within a finite horizon. This approach not only allows for non-smooth solutions, but also provides flexibility in modeling different phenomena. This study investigates the convergence of nonlocal divergence operators, defined with a general flux density function, to their classical counterparts. …
