Readiness Of Nociceptor Cell Bodies To Generate Spontaneous Activity Results From Background Activity Of Diverse Ion Channels And High Input Resistance, Jinbin Tian, Alexis G Bavencoffe, Michael X Zhu, Edgar T Walters

Faculty, Staff and Student Publications

Nociceptor cell bodies generate "spontaneous" discharge that can promote ongoing pain in persistent pain conditions. Little is known about the underlying mechanisms. Recordings from nociceptor cell bodies (somata) dissociated from rodent and human dorsal root ganglia have shown that previous pain in vivo is associated with low-frequency discharge controlled by irregular depolarizing spontaneous fluctuations of membrane potential (DSFs), likely produced by transient inward currents across the somal input resistance. Using mouse nociceptors, we show that DSFs are associated with high somal input resistance over a wide range of membrane potentials, including depolarized levels where DSFs approach action potential (AP) threshold. …

Impact Of Age-Related Change In Caval Flow Ratio On Hepatic Flow Distribution In The Fontan Circulation, Vijay Govindarajan, Lauren Marshall, Akshita Sahni, Maria A Cetatoiu, Emily E Eickhoff, Jocelyn Davee, Nicole St Clair, Noah E Schulz, David M Hoganson, Peter E Hammer, Sunil J Ghelani, Ashwin Prakash, Pedro J Del Nido, Rahul H Rathod

Background: The Fontan operation is a palliative technique for patients born with single ventricle heart disease. The superior vena cava (SVC), inferior vena cava (IVC), and hepatic veins are connected to the pulmonary arteries in a total cavopulmonary connection by an extracardiac conduit or a lateral tunnel connection. A balanced hepatic flow distribution (HFD) to both lungs is essential to prevent pulmonary arteriovenous malformations and cyanosis. HFD is highly dependent on the local hemodynamics. The effect of age-related changes in caval inflows on HFD was evaluated using cardiac magnetic resonance data and patient-specific computational fluid dynamics modeling.

Methods: SVC and …

Calcific aortic stenosis can be considered a model for geriatric cardiovascular conditions due to a confluence of factors. The remarkable technological development of transcatheter aortic valve replacement was studied initially on older adult populations with prohibitive or high-risk for surgical valve replacement. Through these trials, the cardiovascular community has recognized that stratification of these chronologically older adults can be improved incrementally by invoking the concept of frailty and other geriatric risks. Given the complexity of the aging process, stratification by chronological age should only be the initial step but is no longer sufficient to optimally quantify cardiovascular and noncardiovascular risk. …

Dietary Magnesium Replacement For Prevention Of Hypomagnesemia In Patients With Ovarian Cancer Receiving Carboplatin-Based Chemotherapy, Wenli Liu, Larissa Meyer, Meroë Morse, Yisheng Li, Juhee Song, Rosalinda Engle, Gabriel Lopez, Santhosshi Narayanan, Pamela T Soliman, Lois Ramondetta, Eduardo Bruera, Lorenzo Cohen

Faculty, Staff and Student Publications

Purpose: Hypomagnesemia is a common side effect of platinum-based chemotherapy and predicts poor overall survival in some cancers. Standard magnesium replacement strategies are often inadequate for maintaining magnesium levels. We hypothesized that a daily dietary magnesium replacement approach through magnesium-rich foods would help maintain adequate magnesium levels during platinum-based treatment.

Materials and methods: We conducted a prospective feasibility study of magnesium-rich diets in patients 18 years and older with previously untreated ovarian cancer scheduled to receive carboplatin-containing chemotherapy of at least six consecutive cycles. Education about magnesium-rich diets was provided at enrollment and then weekly during chemotherapy. Feasibility was defined …

The spread of prion-like protein aggregates is a common driver of pathogenesis in various neurodegenerative diseases, including Alzheimer's disease (AD) and related Tauopathies. Tau pathologies exhibit a clear progressive spreading pattern that correlates with disease severity. Clinical observation combined with complementary experimental studies has shown that Tau preformed fibrils (PFF) are prion-like seeds that propagate pathology by entering cells and templating misfolding and aggregation of endogenous Tau. While several cell surface receptors of Tau are known, they are not specific to the fibrillar form of Tau. Moreover, the underlying cellular mechanisms of Tau PFF spreading remain poorly understood. Here, it …

Addressing Subject Heterogeneity In Time-Dependent Discrimination For Biomarker Evaluation, Xinyang Jiang, Wen Li, Ruosha Li, Jing Ning

Faculty, Staff and Student Publications

Accurate discrimination has been the central goal in identifying biomarkers for monitoring disease progression and early detection. Acknowledging the fact that discrimination accuracy of biomarkers for a time-to-event outcome often changes over time, local measures such as the time-dependent receiver operating characteristic curve and its area under the curve (AUC) are used to assess time-dependent predictive discrimination. However, such measures do not address subject heterogeneity, although the impact of covariates including demographics, disease-related characteristics, and other clinical information on the discriminatory performance of biomarkers needs to be investigated before their clinical use. We propose the covariate-specific time-dependent AUC, a measure …

Transcriptional Responses Of Different Brain Cell Types To Oxygen Decline, Camille Ravel-Godreuil, Ethan R Roy, Srinivas N Puttapaka, Sanming Li, Yanyu Wang, Xiaoyi Yuan, Holger K Eltzschig, Wei Cao

Faculty, Staff and Student Publications

Brain hypoxia is associated with a wide range of physiological and clinical conditions. Although oxygen is an essential constituent of maintaining brain functions, our understanding of how specific brain cell types globally respond and adapt to decreasing oxygen conditions is incomplete. In this study, we exposed mouse primary neurons, astrocytes, and microglia to normoxia and two hypoxic conditions and obtained genome-wide transcriptional profiles of the treated cells. Analysis of differentially expressed genes under conditions of reduced oxygen revealed a canonical hypoxic response shared among different brain cell types. In addition, we observed a higher sensitivity of neurons to oxygen decline, …

Proton radiography is a promising development in proton therapy, and researchers are currently exploring optimal detector materials to construct proton radiography detector arrays. High-density glass scintillators may improve integrating-mode proton radiography detectors by increasing spatial resolution and decreasing detector thickness. We evaluated several new scintillators, activated with europium or terbium, with proton response measurements and Monte Carlo simulations, characterizing relative luminosity, ionization quenching, and proton radiograph spatial resolution. We applied a correction based on Birks's analytical model for ionization quenching. The data demonstrate increased relative luminosity with increased activation element concentration, and higher relative luminosity for samples activated with europium. …

Anaplastic thyroid carcinoma is arguably the most lethal human malignancy. It often co-occurs with differentiated thyroid cancers, yet the molecular origins of its aggressivity are unknown. We sequenced tumor DNA from 329 regions of thyroid cancer, including 213 from patients with primary anaplastic thyroid carcinomas. We also whole genome sequenced 9 patients using multi-region sequencing of both differentiated and anaplastic thyroid cancer components. Using these data, we demonstrate thatanaplastic thyroid carcinomas have a higher burden of mutations than other thyroid cancers, with distinct mutational signatures and molecular subtypes. Further, different cancer driver genes are mutated in anaplastic and differentiated thyroid …

A Novel Machine Learning Algorithm Selects Proteome Signature To Specifically Identify Cancer Exosomes, Bingrui Li, Fernanda G Kugeratski, Raghu Kalluri

Faculty, Staff and Student Publications

Non-invasive early cancer diagnosis remains challenging due to the low sensitivity and specificity of current diagnostic approaches. Exosomes are membrane-bound nanovesicles secreted by all cells that contain DNA, RNA, and proteins that are representative of the parent cells. This property, along with the abundance of exosomes in biological fluids makes them compelling candidates as biomarkers. However, a rapid and flexible exosome-based diagnostic method to distinguish human cancers across cancer types in diverse biological fluids is yet to be defined. Here, we describe a novel machine learning-based computational method to distinguish cancers using a panel of proteins associated with exosomes. Employing …

Dopamine Lesions Alter The Striatal Encoding Of Single-Limb Gait, Long Yang, Deepak Singla, Alexander K Wu, Katy A Cross, Sotiris C Masmanidis

Faculty, Staff and Student Publications

The striatum serves an important role in motor control, and neurons in this area encode the body's initiation, cessation, and speed of locomotion. However, it remains unclear whether the same neurons also encode the step-by-step rhythmic motor patterns of individual limbs that characterize gait. By combining high-speed video tracking, electrophysiology, and optogenetic tagging, we found that a sizable population of both D1 and D2 receptor expressing medium spiny projection neurons (MSNs) were phase-locked to the gait cycle of individual limbs in mice. Healthy animals showed balanced limb phase-locking between D1 and D2 MSNs, while dopamine depletion led to stronger phase-locking …

Spinal metastases can result in severe neurologic compromise and decreased overall survival. Despite treatment advances, local disease progression is frequent, highlighting the need for novel therapies. Tumor treating fields (TTFields) impair tumor cell replication and are influenced by properties of surrounding tissue. We hypothesized that bone's dielectric properties will enhance TTFields-mediated suppression of tumor growth in spinal metastasis models. Computational modeling of TTFields intensity was performed following surgical resection of a spinal metastasis and demonstrated enhanced TTFields intensity within the resected vertebral body. Additionally, luciferase-tagged human KRIB osteosarcoma and A549 lung adenocarcinoma cell lines were cultured in demineralized bone grafts …
