Introduction: Point-of-care ultrasonography (POCUS) enables clinicians to obtain critical diagnostic information at the bedside, especially in resource-limited settings. This information may include 2D cardiac quantitative data, although measuring the data manually can be time-consuming and subject to user experience. Artificial intelligence (AI) can potentially automate this quantification. This study assessed the interpretation of key cardiac measurements on POCUS images by an AI-enabled device (AISAP Cardio V1.0).

Methods: This retrospective diagnostic accuracy study included 200 POCUS cases from four hospitals (two in Israel and two in the United States). Each case was independently interpreted by three cardiologists and the device for …

Osteoblast-Derived Nerve Growth Factor Supports Skeletal Adaptation To Mechanical Load And The Osteoanabolic Effect Of Gambogic Amide In Mice, Ibtesam Rajpar, Eri Mclaughlin, Gabriella Fioravanti, Nicholas Ruggiero, Nohael Cherian, Liliana Minichiello, Ryan E. Tomlinson

Department of Orthopaedic Surgery Faculty Papers

In adult mice, new bone accrual following mechanical load is mediated by the neurotrophin nerve growth factor (NGF) that is expressed by osteoblasts on the bone surface. NGF can bind to its high affinity receptor, neurotrophic tyrosine kinase receptor type 1 (TrkA), on peripheral sensory nerves resident in bone and support new bone formation. However, the osteoanabolic therapeutic potential of NGF-TrkA signaling to repair bone is limited due to the long-lasting thermal and mechanical hyperalgesia induced by administration of NGF in mice and humans. Here, we investigated whether 1) mature osteoblasts are the primary source of NGF required for bone …

Nemp1 Organizes The Meiotic Telomere-Linc Interface To Control Chromosome Movement And Telomere Integrity, Andrea Jurisicova, Helen Mcneill

Faculty, Staff and Students Publications

Nuclear Envelope Membrane Protein 1 (NEMP1) is highly expressed in oocytes and required for fertility, yet its meiotic function remains poorly understood. Here, we identify NEMP1 as a critical organizer of meiotic telomere-nuclear envelope coupling and chromosome dynamics. Loss of NEMP1 causes telomere aggregation, loss of shelterin protection, telomere shortening, persistent DNA damage, aberrant non-homologous end joining, and chromosome end-to-end fusion, ultimately leading to aneuploidy in mouse oocyte. NEMP1 is required during early fetal meiotic prophase I for telomere-nuclear envelope attachment, bouquet formation, homolog pairing, and synapsis. Live-cell imaging revealed robust rapid prophase movements in wild-type meiocytes, which were nearly …

Background and aims: Adult cardiomyocytes (CMs) have minimal proliferative capacity, limiting the heart's ability to regenerate after injury. While neonatal CMs can proliferate, the signaling pathways governing this process are poorly understood. This study aims to identify and reintroduce the neonatal-specific CM proliferation sensitizing signal to restore cell-cycle in adult CMs.

Methods and results: We identified CD36 as a marker for the neonatal spontaneously proliferating CMs. Bulk and Single cell RNAseq, and spatial transcriptomics analyses of the P1 WT, CD36KO and CD36CKO hearts revealed that a CD36/FABP5/PPARδ signaling axis was uniquely expressed in spontaneously proliferating CMs. Using unbiased metabolomics and …

Department of Neurosurgery Faculty Papers

Parkinson's disease (PD) is a progressive neurological disorder often treated with Deep Brain Stimulation (DBS), a surgical procedure that involves implanting electrodes to improve motor function. Accurate electrode placement is critical for treatment efficacy but can be influenced by tissue deformation, insertion forces, and the mechanical properties of brain tissue. In this study, we investigated the role of layer interface angle as a controlled biomechanical factor affecting insertion forces and electrode deviation. A two-layer agar gel phantom was constructed to produce a prescribed stiffness transition between a lower-stiffness and a higher-stiffness gel layer, and its small-amplitude dynamic shear-stiffness contrast was …

Follistatin Regulates Tooth Root Furcation Morphogenesis, Tak-Heun Kim, Hyuk-Jae Edward Kwon, Sung-Won Cho, Martin Matthew Matzuk, Eui-Sic Cho

Faculty, Staff and Students Publications

Follistatin (Fst), an extracellular inhibitor of the TGF-β signaling pathway, plays a critical role in tooth development, particularly in crown morphogenesis and enamel patterning. While molar root number is conserved within species and between upper and lower jaws, the molecular mechanisms governing root patterning remain largely unknown. To investigate the role of Fst in root formation, we analyzed K14-Cre-mediated Fst knockout mice. During embryonic and early postnatal stages, Fst was dynamically expressed in the dental epithelium including the lingual epithelium, and primary and secondary enamel knots, as well as in the dental mesenchyme at the base of the dental papilla. …

Tarsal Tunnel Syndrome Due To Post-Traumatic Osseous Tunnel Formation: A Rare Case And Surgical Management, Dev Y. Patel, Eshan Doshi, Fiona Zimmerman, Jamal Revolus, Michael Kimball, Michael Franco

Cooper Rowan Medical Journal

Tarsal tunnel syndrome (TTS) is classically a compressive neuropathy of the posterior tibial nerve beneath the flexor retinaculum, presenting with plantar foot pain and paresthesias. Standard surgical management of TTS involves release of the flexor retinaculum to decompress the nerve. We report a rare and unusual case of TTS in which the posterior tibial nerve was encased within a post-traumatic osseous tunnel accompanied by dense fibrotic tissue, representing an atypical and previously undescribed etiology of nerve entrapment. In this case, surgical decompression required a modified approach involving meticulous dissection of the tibial nerve from its encasement by heterotopic ossification and …

Protein O-glucosyltransferase 1 (POGLUT1/Rumi) transfers an O-linked glucose (O-Glc) monosaccharide from UDP-Glc to a serine residue in epidermal growth factor (EGF)-like repeats with a specific consensus sequence. In mammals, GXYLT1 and GXYLT2 transfer xylose to this O-Glc monosaccharide. Previous studies showed that Poglut1 deletion in mice leads to embryonic lethality with defects in crumbs family member 2 (CRB2) trafficking and NOTCH1 signaling. Both CRB2 and Notch receptors have multiple EGF repeats with the O-Glc modification site. However, the roles of xylosyl elongation of O-Glc in protein trafficking and mammalian embryonic development are unknown. Here, we demonstrated that xylosyl elongation of …
