Faculty, Staff and Student Publications

Objective: To describe parents' motivations for and against participation in neonatal research, including the views of those who declined participation.

Study design: We performed 44 semi-structured, qualitative interviews of parents approached for neonatal research. Here we describe their motivations for and against participation.

Results: Altruism was an important reason parents chose to participate. Some hoped participation in research would benefit their infant. Burdens of participation to the family, such as transportation to follow up (distinct from risks/burdens to the infant), were often deciding factors among those who declined participation. Perceived risks to the infant were reasons against participation, but parents …

Mimosa: A Resource Consisting Of Improved Methylome Prediction Models Increases Power To Identify Dna Methylation-Phenotype Associations, Hunter J Melton, Zichen Zhang, Hong-Wen Deng, Lang Wu, Chong Wu

Faculty, Staff and Student Publications

Although DNA methylation (DNAm) has been implicated in the pathogenesis of numerous complex diseases, from cancer to cardiovascular disease to autoimmune disease, the exact methylation sites that play key roles in these processes remain elusive. One strategy to identify putative causal CpG sites and enhance disease etiology understanding is to conduct methylome-wide association studies (MWASs), in which predicted DNA methylation that is associated with complex diseases can be identified. However, current MWAS models are primarily trained using the data from single studies, thereby limiting the methylation prediction accuracy and the power of subsequent association studies. Here, we introduce a new …

Wirelessly Actuated Microfluidic Pump And Valve For Controlled Liquid Delivery In Dental Implants, Yilan Xu, Honglu Lin, Boyang Xiao, Hutomo Tanoto, Joel Berinstein, Alend Khoshnaw, Simon Young, Yuxiao Zhou, Xiaoguang Dong

Faculty, Staff and Student Publications

Enabling minimally invasive and precise control of liquid release in dental implants is crucial for therapeutic functions such as delivering antibiotics to prevent biofilm formation, infusing stem cells to promote osseointegration, and administering other biomedicines. However, achieving controllable liquid cargo release in dental implants remains challenging due to the lack of wireless and miniaturized fluidic control mechanisms. Here wireless miniature pumps and valves that allow remote activation of liquid cargo delivery in dental implants, actuated and controlled by external magnetic fields (< 65 mT), are reported. A magnet-screw mechanism in a fluidic channel to function as a piston pump, alongside a flexible magnetic valve designed to open and close the fluidic channel, is proposed. The mechanisms are showcased by storing and releasing of liquid up to 52 µL in a dental implant. The liquid cargos are delivered directly to the implant-bone interface, a region traditionally difficult to access. On-demand liquid delivery is further showed by a metal implant inside both dental phantoms and porcine jawbones. The mechanisms are promising for controllable liquid release after implant placement with minimal invasion, paving the way for implantable devices that enable long-term and targeted delivery of therapeutic agents in various bioengineering applications.

2020-Current year OA Pubs

PURPOSE: Pain after brachial plexus injury (BPI) can be severely debilitating and is poorly understood. We hypothesized that pain interference (PI) ("the extent to which pain hinders engagement in life") would be predicted by depression, anxiety, severity of pain symptoms, and poorer preoperative muscle function.

METHODS: Among patients in a prospective multicenter BPI cohort study, 37 completed Patient-Reported Outcomes Measurement Information System (PROMIS) PI questionnaires before and 1 year after surgery. At both times, participants completed anxiety and depression questionnaires and BPI-specific measures of pain symptoms, physical limitations, and emotional recovery. Surgeon-graded muscle testing, injury severity, age at the time …

Identifying Dose Constraints For The Parotid Ducts To Minimize Patient-Reported Xerostomia: Is Conventional Mean Dose Sparing Of The Parotid Glands Sufficient?, Manal Ahmidouch, Shiva K Das, Tong Zhu, Colette Shen, Lawrence B Marks, Bhishamjit S Chera, David V Fried

2020-Current year OA Pubs

BACKGROUND AND PURPOSE: The aim of this study was to identify dose constraints for the parotid ducts that limit patient-reported xerostomia and estimate whether these constraints are achieved during conventional parotid gland sparing radiation therapy (PGS-RT).

METHODS AND MATERIALS: Thirty-eight oropharyngeal squamous cell carcinoma patients were treated prospectively on trial with MRI sialography-guided parotid duct sparing radiation therapy (PDS-RT). PDS-RT explicitly minimizes dose to the parotid ducts in addition to PGS-RT. Parotid duct dose constraints were identified that distinguished patients reporting high and low rates of xerostomia.

From A Timeline Contact Graph To Close Contact Tracing And Infection Diffusion Intervention, Yipeng Zhang, Zhifeng Bao, Yuchen Li, Baihua Zheng, Xiaoli Wang

Research Collection School Of Computing and Information Systems

This paper proposes a novel graph structure to address the problems of information spreading in a real-world, frequently updating graph, with two main contributions at hand: accurately tracing infection diffusion according to fine-grained user movements and finding vulnerable vertices under the virus immunization scenario to mitigate infection diffusion. Unlike previous work that primarily predicts the long-term epidemic trend at the census level, this study aims to intervene in the short-term at the individual level. Therefore, two downstream tasks are formulated to illustrate practicalities: Epidemic Mitigating in Public Area problem (EMA) and Epidemic Maximized Spread in Public Area problem (ESA), where …

Low Intensity Mechanical Signals Promote Proliferation In A Cell-Specific Manner: Tailoring A Non-Drug Strategy To Enhance Biomanufacturing Yields, M Ete Chan, Christopher Ashdown, Lia Strait, Sishir Pasumarthy, Abdullah Hassan, Steven Crimarco, Chanpreet Singh, Vihitaben S Patel, Gabriel Pagnotti, Omor Khan, Gunes Uzer, Clinton T Rubin

Faculty, Staff and Student Publications

Biomanufacturing relies on living cells to produce biotechnology-based therapeutics, tissue engineering constructs, vaccines, and a vast range of agricultural and industrial products. With the escalating demand for these bio-based products, any process that could improve yields and shorten outcome timelines by accelerating cell proliferation would have a significant impact across the discipline. While these goals are primarily achieved using biological or chemical strategies, harnessing cell mechanosensitivity represents a promising - albeit less studied - physical pathway to promote bioprocessing endpoints, yet identifying which mechanical parameters influence cell activities has remained elusive. We tested the hypothesis that mechanical signals, delivered non-invasively …

Constructing Phylogenetic Trees For Microbiome Data Analysis: A Mini-Review, Ruitao Liu, Xi Qiao, Yushu Shi, Christine B Peterson, William S Bush, Fabio Cominelli, Ming Wang, Liangliang Zhang

Faculty, Staff and Student Publications

As next-generation sequencing technologies advance rapidly and the cost of metagenomic sequencing continues to decrease, researchers now face an unprecedented volume of microbiome data. This surge has stimulated the development of scalable microbiome data analysis methods and necessitated the incorporation of phylogenetic information into microbiome analysis for improved accuracy. Tools for constructing phylogenetic trees from 16S rRNA sequencing data are well-established, as the highly conserved regions of the 16S gene are limited, simplifying the identification of marker genes. In contrast, metagenomic and whole genome shotgun (WGS) sequencing involve sequencing from random fragments of the entire gene, making identification of consistent …

Aging-Associated Mechanisms Of Atrial Fibrillation Progression And Their Therapeutic Potential, Shuai Zhao, Aaron M Johnston, Chi Him Kendrick Yiu, Lucia M Moreira, Svetlana Reilly, Xander H T Wehrens

Faculty, Staff and Students Publications

Atrial fibrillation (AF) is the most common sustained arrhythmia, with a particularly high prevalence in the elderly. As the global aging population rapidly expands, it is increasingly important to examine how alterations to the aging heart contribute to an increased AF susceptibility. This work critically reviews the key molecular mechanisms that may underpin the complex association between aging and AF. Moreover, we identify emerging novel opportunities for therapeutic intervention that may be able to prevent and/or improve the current treatment paradigms for age-related AF. This review contributes to a holistic understanding of the intricate relationship between aging and AF.

Ectopic Dental Canal: A Case Report Highlighting A Unique Bifid Mandibular Canal Variant, Kevin W. Yu, Manal Hamdan, Stephanie J. Sidow

School of Dentistry Faculty Research and Publications

Bifid mandibular canals are common anatomical findings with variations based on direction and location of branching, which carry significant clinical implications for endodontic and surgical dental procedures. This case report describes a previously unreported ectopic dental canal that branches off the superior border of the mandibular canal, enters the apex of a mandibular second molar, traverses through the root, anastomoses with the root canal system, and subsequently exits through the lingual aspect of the root. The anastomosis of this ectopic dental canal with the mesial lingual canal led to significant bleeding during rotary instrumentation. This unique anatomical variation demonstrates the …

Biomedical Engineering Faculty Publications and Presentations

Gene replacement therapies primarily rely on adeno-associated virus (AAV) vectors for transgene expression. However, episomal expression can decline over time due to vector loss or epigenetic silencing. CRISPR-based integration methods offer promise for long-term transgene insertion. While the development of transgene integration methods has made substantial progress, identifying optimal insertion loci remains challenging. Skeletal muscle is a promising tissue for gene replacement owing to low invasiveness of intramuscular injections, relative proportion of body mass, the multinucleated nature of muscle, and the potential for reduced adverse effects. Leveraging endogenous promoters in skeletal muscle, we evaluated two highly expressing loci using homology-independent …

The Brief Mind Wandering Three-Factor Scale (Bmw-3), Anna-Lena Schubert, Gidon T Frischkorn, Kathrin Sadus, Matthew S Welhaf, Michael J Kane, Jan Rummel

2020-Current year OA Pubs

In recent years, researchers from different fields have become increasingly interested in measuring individual differences in mind wandering as a psychological trait. Although there are several questionnaires that allow for an assessment of people's perceptions of their mind wandering experiences, they either define mind wandering in a very broad sense or do not sufficiently separate different aspects of mind wandering. Here, we introduce the Brief Mind Wandering Three-Factor Scale (BMW-3), a 12-item questionnaire available in German and English. The BMW-3 conceptualizes mind wandering as task-unrelated thought and measures three dimensions of mind wandering: unintentional mind wandering, intentional mind wandering, and …
