Opaque Ontology: Neuroimaging Classification Of Icd-10 Diagnostic Groups In The Uk Biobank, Ty Easley, Xiaoke Luo, Kayla Hannon, Petra Lenzini, Janine Bijsterbosch

2020-Current year OA Pubs

BACKGROUND: The use of machine learning to classify diagnostic cases versus controls defined based on diagnostic ontologies such as the International Classification of Diseases, Tenth Revision (ICD-10) from neuroimaging features is now commonplace across a wide range of diagnostic fields. However, transdiagnostic comparisons of such classifications are lacking. Such transdiagnostic comparisons are important to establish the specificity of classification models, set benchmarks, and assess the value of diagnostic ontologies.

RESULTS: We investigated case-control classification accuracy in 17 different ICD-10 diagnostic groups from Chapter V (mental and behavioral disorders) and Chapter VI (diseases of the nervous system) using data from the …

Automated Breast Density Assessment For Full-Field Digital Mammography And Digital Breast Tomosynthesis, Shu Jiang, Debbie L Bennett, Simin Chen, Adetunji T Toriola, Graham A Colditz

2020-Current year OA Pubs

Mammographic density is a strong risk factor for breast cancer and is reported clinically as part of Breast Imaging Reporting and Data System (BI-RADS) results issued by radiologists. Automated assessment of density is needed that can be used for both full-field digital mammography (FFDM) and digital breast tomosynthesis (DBT) as both types of exams are acquired in standard clinical practice. We trained a deep learning model to automate the estimation of BI-RADS density from a prospective Washington University clinic-based cohort of 9,714 women, entering into the cohort in 2013 with follow-up through October 31, 2020. The cohort included 27% non-Hispanic …

Label Free, Capillary-Scale Blood Flow Mapping In Vivo Reveals That Low-Intensity Focused Ultrasound Evokes Persistent Dilation In Cortical Microvasculature, Yubing Y Shen, Jyoti V Jethe, Ashlan P Reid, Jacob Hehir, Marcello Magri Amaral, Chao Ren, Senyue Hao, Chao Zhou, Jonathan A N Fisher

2020-Current year OA Pubs

Non-invasive, low intensity focused ultrasound is an emerging neuromodulation technique that offers the potential for precision, personalized therapy. An increasing body of research has identified mechanosensitive ion channels that can be modulated by FUS and support acute electrical activity in neurons. However, neuromodulatory effects that persist from hours to days have also been reported. The brain's ability to provide blood flow to electrically active regions involves a multitude of non-neuronal cell types and signaling pathways in the cerebral vasculature; an open question is whether persistent effects can be attributed, at least partly, to vascular mechanisms. Using an in vivo optical …

Intrinsic Adaptive Plasticity In Mouse And Human Sensory Neurons, Lisa A Mcilvried, John Smith Del Rosario, Melanie Y Pullen, Andi Wangzhou, Tayler D Sheahan, Andrew J Shepherd, Richard A Slivicki, John A Lemen, Theodore J Price, Bryan A Copits, Robert W Gereau

2020-Current year OA Pubs

In response to changes in activity induced by environmental cues, neurons in the central nervous system undergo homeostatic plasticity to sustain overall network function during abrupt changes in synaptic strengths. Homeostatic plasticity involves changes in synaptic scaling and regulation of intrinsic excitability. Increases in spontaneous firing and excitability of sensory neurons are evident in some forms of chronic pain in animal models and human patients. However, whether mechanisms of homeostatic plasticity are engaged in sensory neurons of the peripheral nervous system (PNS) is unknown. Here, we show that sustained depolarization (induced by 24-h incubation in 30 mM KCl) induces compensatory …

Null Method To Estimate The Maximal Pa At Subsaturating Concentrations Of Agonist, Allison L Germann, Spencer R Pierce, Joe Henry Steinbach, Gustav Akk

2020-Current year OA Pubs

The maximal probability of being in an active state (PA,max) is a measure of gating efficacy for a given agonist acting on a given receptor channel. In macroscopic electrophysiological recordings, PA,max is typically estimated by comparing the amplitude of the current response to a saturating concentration of a test agonist to that of a reference agonist with known PA. Here, we describe an approach to estimate the PA,max for low-efficacy agonists at subsaturating concentrations. In this approach, the amplitude of the response to a high-efficacy control agonist applied alone is compared with the amplitude of the response to a control …

Integrative Multiomics Reveals Common Endotypes Across Psen1, Psen2, And App Mutations In Familial Alzheimer's Disease, Phoebe Valdes, Andrew B Caldwell, Qing Liu, Michael Q Fitzgerald, Srinivasan Ramachandran, Celeste M Karch, Dominantly Inherited Alzheimer Network (Dian), Douglas R Galasko, Shauna H Yuan, Steven L Wagner, Shankar Subramaniam

2020-Current year OA Pubs

BACKGROUND: PSEN1, PSEN2, and APP mutations cause Alzheimer's disease (AD) with an early age at onset (AAO) and progressive cognitive decline. PSEN1 mutations are more common and generally have an earlier AAO; however, certain PSEN1 mutations cause a later AAO, similar to those observed in PSEN2 and APP.

METHODS: We examined whether common disease endotypes exist across these mutations with a later AAO (~ 55 years) using hiPSC-derived neurons from familial Alzheimer's disease (FAD) patients harboring mutations in PSEN1

RESULTS: We identified common disease endotypes, such as dedifferentiation, dysregulation of synaptic signaling, repression of mitochondrial function and metabolism, and inflammation. …

A Propofol Binding Site In The Voltage Sensor Domain Mediates Inhibition Of Hcn1 Channel Activity, Verena Burtscher, Lei Wang, John Cowgill, Zi-Wei Chen, Christopher Edge, Edward Smith, Yongchang Chang, Lucie Delemotte, Alex S Evers, Baron Chanda

2020-Current year OA Pubs

Hyperpolarization-activated and cyclic nucleotide-gated (HCN) ion channels are members of the cyclic nucleotide-binding family and are crucial for regulating cellular automaticity in many excitable cells. HCN channel activation contributes to pain perception, and propofol, a widely used anesthetic, acts as an analgesic by inhibiting the voltage-dependent activity of HCN channels. However, the molecular determinants of propofol action on HCN channels remain unknown. Here, we use a propofol-analog photoaffinity labeling reagent to identify propofol binding sites in the human HCN1 isoform. Mass spectrometry analyses combined with molecular dynamics simulations show that a binding pocket is formed by extracellularly facing residues in …

2020-Current year OA Pubs

BACKGROUND: Antiretroviral therapy (ART) is recommended for all individuals with HIV infection, including those with acute HIV-1 infection (AHI). While recommendations are similar to those for chronic infection, efficacy data regarding treatment of acute HIV is limited.

METHODS: This was a single arm, 96-week study of a once-daily integrase inhibitor (INSTI)-based regimen using elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF) in AHI. Primary endpoint was proportion of participants with HIV-1 RNA <200 copies/mL and <50 copies/mL by treatment weeks 24 and 48, respectively. We also examined time to viral suppression and weight gain after treatment initiation. Outcomes and characteristics were compared with a historical AHI cohort using a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen with efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF).

RESULTS: Thirty-three participants with AHI were enrolled with 31 available for analyses. Most were African American (61%) and men who have sex with men (73%). Median age was 26 (IQR 22-42). Demographics …

T Helper 2 Cell-Directed Immunotherapy Eliminates Precancerous Skin Lesions, Tomonori Oka, Neel S. Raval, Mary Tabacchi, Lynn A. Cornelius, Et Al.

2020-Current year OA Pubs

The continuous rise in skin cancer incidence highlights an imperative for improved skin cancer prevention. Topical calcipotriol-plus-5-fluorouracil (calcipotriol-plus-5-FU) immunotherapy effectively eliminates precancerous skin lesions and prevents squamous cell carcinoma (SCC) in patients. However, its mechanism of action remains unclear. Herein, we demonstrate that calcipotriol-plus-5-FU immunotherapy induces T helper type 2 (Th2) immunity, eliminating premalignant keratinocytes in humans. CD4+ Th2 cells were required and were sufficient downstream of thymic stromal lymphopoietin cytokine induction by calcipotriol to suppress skin cancer development. Th2-associated cytokines induced IL-24 expression in cancer cells, resulting in toxic autophagy and anoikis followed by apoptosis. Calcipotriol-plus-5-FU immunotherapy was dependent …

Mouse models are vital tools for discerning the relative contributions of host and microbial genetics to disease, often requiring the transfer of microbiota between different mouse strains. Transfer methods include antibiotic treatment of recipients and colonization using either co-housing with donors or the transplantation of faecal or caecal donor material. However, the efficiency and dynamics of these methods in reconstituting recipients with donor microbes is not well understood. We thus directly compared co-housing, faecal transplantation, and caecal transplantation methods. Donor mice from Taconic Biosciences, possessing distinct microbial communities, served as the microbial source for recipient mice from Jackson Laboratories, which …

N-Linked Fucosylated Glycans Are Biomarkers For Prostate Cancer With A Neuroendocrine And Metastatic Phenotype, Joseph E Ippolito, Hani Nakhoul, Cody Weimholt, Elena Nunez, Nikolaos A Trikalinos, Et Al.

2020-Current year OA Pubs

Prostate cancer is a heterogeneous disease with a spectrum of pathology and outcomes ranging from indolent to lethal. Although there have been recent advancements in prognostic tissue biomarkers, limitations still exist. We leveraged matrix-assisted laser desorption/ionization imaging of formalin-fixed, paraffin embedded prostate cancer specimens to determine if N-linked glycans expressed in the extracellular matrix of lethal neuroendocrine prostate cancer were also expressed in conventional prostate adenocarcinomas that were associated with poor outcomes. We found that N-glycan fucosylation was abundant in neuroendocrine prostate cancer as well as adenocarcinomas at the time of prostatectomy that eventually developed recurrent metastatic disease. Analysis of …

Two-Hit Mouse Model Of Heart Failure With Preserved Ejection Fraction Combining Diet-Induced Obesity And Renin-Mediated Hypertension, Justin H Berger, Xian Chen, Attila Kovacs, Et Al.

2020-Current year OA Pubs

Heart failure with preserved ejection fraction (HFpEF) is increasingly common but its pathogenesis is poorly understood. The ability to assess genetic and pharmacologic interventions is hampered by the lack of robust preclinical mouse models of HFpEF. We developed a novel "two-hit" model, which combines obesity and insulin resistance with chronic pressure overload to recapitulate clinical features of HFpEF. C57Bl6/NJ mice fed a high-fat diet (HFD) for > 10 weeks were administered an AAV8-driven vector resulting in constitutive overexpression of mouse Renin1d. HFD-Renin (aka "HFpEF") mice demonstrated obesity and insulin resistance, moderate left ventricular hypertrophy, preserved systolic function, and diastolic dysfunction indicated …

Delandistrogene moxeparvovec is an rAAVrh74 vector-based gene transfer therapy that delivers a transgene encoding delandistrogene moxeparvovec micro-dystrophin, an engineered, functional form of dystrophin shown to stabilize or slow disease progression in DMD. It is approved in the US and in other select countries. Two serious adverse event cases of immune-mediated myositis (IMM) were reported in the phase Ib ENDEAVOR trial (NCT04626674). We hypothesized that immune responses to the micro-dystrophin transgene product may have mediated these IMM events. An interferon-gamma ELISpot assay was used to detect T cell responses to delandistrogene moxeparvovec micro-dystrophin peptide pools. ELISpot analysis suggested that IMM resulted …

Histone post-translational modifications (PTMs) regulate gene expression patterns through epigenetic mechanisms. The five histone proteins (H1, H2A, H2B, H3, and H4) are extensively modified, with over 75 distinct modification types spanning more than 200 sites. Despite strong advances in mass spectrometry (MS)-based approaches, identification and quantification of modified histone peptides remains challenging because of factors, such as isobaric peptides, pseudo-isobaric PTMs, and low stoichiometry of certain marks. Here, we describe the development of a new high-throughput method to identify and quantify over 150 modified histone peptides by LC-MS. Fast gradient microflow liquid chromatography and variable window sequential windows acquisition of …
