Mild Cognitive Impairment (MCI) is a clinical prodromal stage of Alzheimer's disease. Enhancing executive functions in patients with MCI could optimize cognitive compensatory mechanisms and slow cognitive decline. The prefrontal cortex (PFC) and its connections to the hippocampus support executive functions, including working memory. Transcranial alternating current stimulation (tACS) can modulate these connections by engaging theta-gamma coupling (TGC) and may thereby strengthen working memory. This study, "tACS to engage theta-gamma coupling and enhance working memory in MCI" (tACS-MCI), will assess the feasibility and cognitive effects of EEG and MRI-guided individualized tACS. The stimulation will target the prefrontal and temporal cortices …

Integrative Multi-Omics Approach For Improving Causal Gene Identification, Austin King, Chong Wu

Faculty, Staff and Student Publications

Transcriptome-wide association studies (TWAS) have been widely used to identify thousands of likely causal genes for diseases and complex traits using predicted expression models. However, most existing TWAS methods rely on gene expression alone and overlook other regulatory mechanisms of gene expression, including DNA methylation and splicing, that contribute to the genetic basis of these complex traits and diseases. Here we introduce a multi-omics method that integrates gene expression, DNA methylation, and splicing data to improve the identification of associated genes with our traits of interest. Through simulations and by analyzing genome-wide association study (GWAS) summary statistics for 24 complex …

Integrating Multi-Omics Data To Uncover Prostate Tissue Dna Methylation Biomarkers And Target Genes For Prostate Cancer Risk, Shuai Liu, Jingjing Zhu, Dylan Green, Hua Zhong, Quan Long, Chong Wu, Liang Wang, Youping Deng, Lang Wu

Faculty, Staff and Student Publications

Previous studies have indicated that specific CpG sites may be linked to the risk of prostate cancer (PCa) by regulating the expression of PCa target genes. However, most existing studies aim to identify DNA methylation (DNAm) biomarkers through blood tissue genetic instruments, which impedes the identification of relevant biomarkers in prostate tissue. To identify PCa risk-associated CpG sites in prostate tissue, we established genetic prediction models of DNAm levels using data from normal prostate samples in the GTEx (N = 108) and assessed associations between genetically predicted DNAm in prostate and PCa risk by studying 122,188 cases and 604,640 controls. …

Faculty, Staff and Student Publications

Introduction: In today's 24/7 society, circadian misalignment caused by environmental and lifestyle factors is associated with various adverse health consequences. Understanding tissue-specific pathology is required to counter this growing public health challenge. A potential association of environmental circadian misalignment with sarcopenia, or accelerated loss of skeletal muscle strength and mass, is poorly documented.

Methods: 14-week-old wild-type C57BL/6J male mice were exposed to a chronic jet lag (CJL) paradigm consisting of an 8-h phase advance every 4 days (the ADV group) or a fixed light-dark cycle (the LD group) for 64 weeks. Grip strength was measured during the experiment, and hindlimb …

In part 1, current clinical utilization and practice are reviewed, giving the context and history of RBE. Evidence for variation in RBE is presented along with the concept of linear energy transfer (LET). The intertwined nature of …

In Utero Alcohol And Tobacco Exposure, Maternal Depression, And Maternal Obesity Are Associated With Impaired Oligodendrocyte Differentiation In The Developing Brain, Uday Bharai, Jamal Hamze, Benjamin Zhang, Monica Hampe, Emily Sparks, Nana Merabova, Gabriel Tatevosian, Armine Darbinyan, Mary F Morrison, Laura Goetzl, Nune Darbinian, Michael Selzer

Faculty, Staff and Student Publications

Introduction: Fetal alcohol spectrum disorder (FASD) is the leading preventable cause of pediatric cognitive disability and is associated with dysmyelination. We examined possible clinical co-determinants that might interact with EtOH in impairing oligodendrocyte (OL) development. Women who drink, including pregnant women, also disproportionately suffer from depression (mDepression), which we have shown is a risk factor for FASD. Might depression during pregnancy contribute to OL pathology? Maternal obesity (mObesity) also inhibits white matter development in fetal brain. Finally, tobacco exposure inhibits not only OL development, but also the production of structural proteins, such as actin. Our human biobank derived from voluntarily …

Daily Movement Activities Are Associated With Within-Person Instability Of Cognitive Function In Older Adults: Evidence From An Ambulatory Assessment Study, Chih-Hsiang Yang, Donald Hedeker, Jongwon Lee, Halle Prine, Donna Coffman, Jingkai Wei, Jonathan George Hakun

Faculty, Staff and Student Publications

Background and objectives: Physical inactivity and excessive sedentary time (ST) are associated with poor cognitive health in older adults. However, current literature largely relies on cross-sectional designs or in-lab cognitive assessments, which do not adequately reflect cognitive function in naturalistic settings. Further, existing studies have largely overlooked the variability or the instability in daily cognitive function, which represents a critical marker of cognitive decline. This ambulatory assessment study examined the temporal associations of daily movement behaviors with the mean levels and the variability of cognition among older adults at risk of dementia.

Research design and methods: 96 older adults from …

Faculty, Staff and Student Publications

Comorbidities are common in Parkinson’s disease and significantly impact the disease progression and management. While polygenic scores have been widely used to assess genetic risk for complex diseases, their role in comorbidity presentation in Parkinson’s disease remains unclear. This study investigates whether genetic predisposition to comorbidities, as measured by polygenic scores, differs between individuals with Parkinson’s disease and the general population and explores how genetic risk influences disease onset and sex-related differences. We analysed data from 4144 individuals with Parkinson’s disease and 370 480 individuals from the general population in the UK Biobank, focusing on four comorbidities with high-quality genome-wide …

Faculty, Staff and Student Publications

Eight-and-a-half syndrome is a rare neuro-ophthalmic syndrome characterized by conjugate horizontal gaze palsy, ipsilateral internuclear ophthalmoplegia, and ipsilateral facial nerve palsy. It results from a lesion affecting the paramedian pontine reticular formation, the medial longitudinal fasciculus, and the abducens nucleus of the same side, at the level of the lower pons. We present a case of a 49-year-old man with 2-week diplopia and 3-day right-sided facial droop, drooling, and dysarthria. CT angiography of the head and neck revealed atherosclerotic disease, with decreased caliber of the basilar artery at the level of the pons. Brain MRI showed a subacute ischemic lesion …

Long-Term Dynamic Profiles Of Cognitive Kinases Induced By Different Learning Protocols, Yili Zhang, Rong-Yu Liu, Paul Smolen, John H Byrne

Faculty, Staff and Student Publications

Learning is associated with activation of multiple protein kinases, but few details are known about the activation dynamics in response to different learning protocols. We addressed this issue by examining the long-term dynamics of kinases critical for long term synaptic facilitation (LTF) of the Aplysia sensorimotor synapse. Three serotonin (5-HT) protocols have been found to induce LTF with distinct effectiveness: the five-pulse regular-spaced Standard protocol; the five-pulse irregular-spaced Enhanced protocol; and the two-pulse protocol with an interval of 45 min. We previously compared long-term dynamics of the mitogen-activated protein kinase (MAPK) isoform ERK after these protocols. Here we examined the …

Quantitatively Assessing The Impact Of The Quality Of Snomed Ct Subtype Hierarchy On Cohort Queries, Xubing Hao, Xiaojin Li, Yan Huang, Jay Shi, Rashmie Abeysinghe, Cui Tao, Kirk Roberts, Guo-Qiang Zhang, Licong Cui

Faculty, Staff and Student Publications

Objective: SNOMED CT provides a standardized terminology for clinical concepts, allowing cohort queries over heterogeneous clinical data including Electronic Health Records (EHRs). While it is intuitive that missing and inaccurate subtype (or is-a) relations in SNOMED CT reduce the recall and precision of cohort queries, the extent of these impacts has not been formally assessed. This study fills this gap by developing quantitative metrics to measure these impacts and performing statistical analysis on their significance.

Material and methods: We used the Optum de-identified COVID-19 Electronic Health Record dataset. We defined micro-averaged and macro-averaged recall and precision metrics to assess the …

Faculty, Staff and Student Publications

Objectives: Immigrants in the United States are more likely than nonimmigrants to experience risk factors for intimate partner violence (IPV) and problems in getting support. The COVID-19 pandemic and recent incidents of xenophobia and anti-immigrant sentiment may have exacerbated exposure to IPV risk factors. We examined immigrant experiences of IPV before and during the COVID-19 pandemic.

Methods: This study identified changes in characteristics of abuse, services used, referrals, and barriers to services among those who contacted the National Domestic Violence Hotline (NDVH) and identified as immigrants, reported immigration status as a concern, needed immigration support, and/or identified immigration status as …

Limitations Of The Radiotheranostic Concept In Neuroendocrine Tumors Due To Lineage-Dependent Somatostatin Receptor Expression On Hematopoietic Stem And Progenitor Cells, Nghia Nguyen, Yu Min, Jennifer Rivière, Mark Van Der Garde, Sukhen Ghosh, Laura M Bartos, Matthias Brendel, Florian Bassermann, Ali Azhdarinia, Wolfgang A Weber, Katharina S Götze, Susanne Kossatz

Faculty, Staff and Student Publications

Rationale: Radiopharmaceutical therapy (RPT) has become an effective treatment option for neuroendocrine tumors (NETs) and castration-resistant prostate cancer and is in clinical development for many indications. One of the major advantages of theranostic RPT is that the distribution of radiopharmaceuticals in the human body can be imaged, and radiation doses to the patient's organs can be calculated. However, accurate dosimetry may be fundamentally limited by microscopic heterogeneity of radiopharmaceutical distribution.

Methods: We developed fluorescent analogs of somatostatin-receptor-subtype 2 (SSTR2) targeting Lutetium-177 labeled radiopharmaceuticals that are clinically used in patients with NETs and studied their uptake by hematopoietic stem and progenitor …

The Interplay Between Pulse Width And Activation Depth In Tens: A Computational Study, Alexander Guillen, Dennis Q Truong, Yusuf O Cakmak, Sheng Li, Abhishek Datta

Faculty, Staff and Student Publications

Background: Transcutaneous electrical nerve stimulation (TENS) has been a commonly used modality to relieve aches and pain for over 40 years. Commercially available devices provide multiple therapy modes involving a different combination of frequency and pulse width with intensity. While frequency sets sensation, intensity helps determine tolerability, longer pulse width is reported to induce a feeling of deeper stimulation. In fact, longer pulse width has been empirically shown to deliver current into deeper tissues, but in context of other electrical stimulation modalities. The goal of this study was to unpack the relationship between pulse width and activation depth in TENS. …

Administration Of Anti-Gfap Antibodies Increases Cgrp Expression And Increases Pain Hypersensitivity In Spinal Cord Injured Animals, Georgene W Hergenroeder, Samuel T Molina, Juan J Herrera

Faculty, Staff and Student Publications

Background: Spinal cord injury (SCI) results in a multitude of cellular and pathological changes including neuronal loss, axonal damage, gliosis, and loss of motor and sensory function. In 40%-70% of patients, SCI can also trigger the development of neuropathic pain. Our previous study demonstrated that SCI patients who developed autoantibodies to glial fibrillary acidic protein (GFAP) were at increased risk for the subsequent development of neuropathic pain. However, whether GFAP autoantibodies (GFAPab) contribute to the development of neuropathic pain after SCI had yet to be examined.

Objective: Using a mid-thoracic contusion model of SCI in male Sprague-Dawley rats, we examined …

Faculty, Staff and Student Publications

AIMS: The haemodynamic physiology of the aortic valve has attracted renewed attention after the introduction of transcatheter aortic valve implantation (TAVI). Understanding normal valve function, especially under stress conditions, permits identification of early pathology and quantification of the extent to which TAVI restores normalcy. We aimed to describe the haemodynamic behaviour of a normal aortic valve during stress via invasive, non-invasive, and computational techniques.

METHODS AND RESULTS: Our cohort included subjects already undergoing invasive coronary angiography for clinical indications. Haemodynamic measurements were made invasively and non-invasively along with dobutamine infusion. Additionally, patient-specific anatomy from computed tomographic imaging served as input …

Targeting Ferroptosis For Neuroprotection: Potential Therapeutic Avenues In Neurodegenerative And Neuropsychiatric Diseases, Muhammad S Khan, Qichan Hu, Kendrix Okeibunor, Liang Ma, Jean C Bopassa

Faculty, Staff and Student Publications

Ferroptosis is an iron-dependent programmed cell death that plays an important role in neurodegenerative and neuropsychiatric diseases. In the present study, we have highlighted how different risk factors are involved in the induction of ferroptosis in brain cells. In addition, we also demonstrated how ferroptosis plays an important role in different brain diseases. In our study why we focused and elaborated on the mechanisms of ferroptosis only in brain cells (Neurons, oligodendrocytes, and microglia) because they are particularly vulnerable to such kind of cell death. Additionally, brain cells are more dependent on mitochondrial function, iron regulation, and high levels of …

Prenatal Alcohol Exposure Inhibits Transient Expression Of Autophagy And Synaptic Proteins In Developing Brain, Monica Hampe, Nune Darbinian, Nana Merabova, Armine Darbinyan, Jamal Hamze, Uday Bharai, Yuri Persidsky, Mary F Morrison, Shohreh Amini, Laura Goetzl, Michael E Selzer

Faculty, Staff and Student Publications

Introduction: Neuronal apoptosis and consequent inhibition of autophagy, with loss of synaptic connections are central events in the genesis of fetal alcohol spectrum disorders (FASD). However, studies of molecular mechanisms of autophagy in human fetal brain are limited. Recently, prenatal exposure to EtOH was associated with reduced miRNA-9 levels in fetal brain-derived exosomes (FB- Es) isolated from maternal plasma, which correlated with small eyes, an anatomical hallmark of fetal alcohol syndrome (FAS). Since miR-9 targets several genes that regulate synaptic plasticity, EtOH-induced inhibition of miR-9 could potentially result in dysregulation of genes involved in synaptogenesis/plasticity.

Methods: Rats were fed a …

How Different Is Invasive Coronary Physiology In The Left Anterior Descending Artery?, Nils P Johnson, K Lance Gould

Faculty, Staff and Student Publications

Given the large amount of myocardium supplied by the left anterior descending (LAD) artery, it understandably receives additional scrutiny during coronary angiography. However, these same features make the interpretation of pressure wire physiology more nuanced to avoid overtreatment. This review provides case examples to underpin an extensive literature review supporting the argument that a "positive" fractional flow reserve (FFR) in the LAD needs to be approached with caution. A large hyperemic gradient, or low FFR, can arise from either a severe and focal lesion in conjunction with low flow or diffuse disease coupled with intact or normal flow. Separating these …
