Idiopathic pulmonary fibrosis is a major cause of death with few treatment options. Here, we demonstrate the therapeutic efficacy for lung fibrosis of adult lung cell transplantation using a single-cell suspension of the entire lung in two distinct mouse systems: bleomycin treatment and mice lacking telomeric repeat-binding factor 1 expression in alveolar type 2 (AT2) cells (SPC-Cre TRF1fl/fl), spontaneously developing fibrosis. In both models, the progression of fibrosis was associated with reduced levels of host lung progenitors, enabling engraftment of donor progenitors without any additional conditioning, in contrast to our previous studies. Two months after transplantation, engrafted progenitors …

Background

• Surgery is the primary form of definitive treatment for early-stage lung cancer.
• Poor lung function before surgery places patients at high risk of pulmonary complications after resection.
• Surgeons evaluate patient fitness for surgery using pulmonary function tests (PFTs) to calculate the predicted postoperative PFT (ppoPFT).
• Conventional ppoPFT calculations assume homogeneous lung function, which can be inaccurate.
• 4DCT-ventilation is a novel lung function imaging modality developed in radiation oncology that uses 4DCT data to calculate high-resolution ventilation maps.

Outdoor Recreation For People With Spinal Cord Injuries: An Educational Video Series, Siarra Walker

Student Capstone Papers

More than 15 million people globally are living with spinal cord injury (SCI). Only half of people with SCI engage in leisure activities and approximately 71% of the population reports dissatisfaction in their leisure participation. There are numerous intrinsic and extrinsic barriers that lead to these significant declines in leisure exploration and participation, including lack of knowledge and inaccurate accessible online information. In correlation with these barriers, occupational therapy practitioners underutilize leisure participation during the rehabilitation process for people with SCI and this is an underreported topic in the literature. Occupational therapy practitioners and people with SCI lack knowledge of …

Ontology is essential for achieving health information and information technology application interoperability in the biomedical fields and beyond. Traditionally, ontology construction is carried out manually by human domain experts (HDE). Here, we explore an active learning approach to automatically identify candidate terms from publications, with manual verification later as a part of a deep learning model training and learning process. We introduce the overall architecture of the active learning pipeline and present some preliminary results. This work is a critical and complementary component in addition to manually building the ontology, especially during the long-term maintenance stage.

BACKGROUND: Autism spectrum disorder (ASD), a neurodevelopmental disorder defined by social communication deficits plus repetitive behaviors and restricted interests, currently affects 1/36 children in the general population. Recent advances in functional brain imaging show promise to provide useful biomarkers of ASD diagnostic likelihood, behavioral trait severity, and even response to therapeutic intervention. However, current gold-standard neuroimaging methods (e.g., functional magnetic resonance imaging, fMRI) are limited in naturalistic studies of brain function underlying ASD-associated behaviors due to the constrained imaging environment. Compared to fMRI, high-density diffuse optical tomography (HD-DOT), a non-invasive and minimally constraining optical neuroimaging modality, can overcome these limitations. …

Developmental and epileptic encephalopathies (DEEs) feature altered brain development, developmental delay and seizures, with seizures exacerbating developmental delay. Here we identify a cohort with biallelic variants in DENND5A, encoding a membrane trafficking protein, and develop animal models with phenotypes like the human syndrome. We demonstrate that DENND5A interacts with Pals1/MUPP1, components of the Crumbs apical polarity complex required for symmetrical division of neural progenitor cells. Human induced pluripotent stem cells lacking DENND5A fail to undergo symmetric cell division with an inherent propensity to differentiate into neurons. These phenotypes result from misalignment of the mitotic spindle in apical neural progenitors. Cells …

Although long-term survival in Rett syndrome (RTT) has been observed, limited information on older people with RTT exists. We hypothesized that increased longevity in RTT would be associated with genetic variants in MECP2 associated with milder severity, and that clinical features would not be static in older individuals. To address these hypotheses, we compared the distribution of MECP2 variants and clinical severity between younger individuals with Classic RTT (under 30 years old) and older individuals (over 30 years old). Contrary to expectation, enrichment of a severe MECP2 variant (R106W) was observed in the older cohort. Overall severity was not different …

We identify a population of PRTG+ve MYChigh NESTINlow stem cells in the four-week-old human embryonic hindbrain that subsequently localizes to the ventricular zone of the rhombic lip (RLVZ). Oncogenic transformation of early Prtg+ve rhombic lip stem cells initiate Group 3 Medulloblastoma (Gr3-MB)-like tumors. PRTG+ve stem-cells grow adjacent to a human specific interposed vascular plexus in the RLVZ, a phenotype which is recapitulated in Gr3-MB, but not other types of medulloblastoma. Co-culture of Gr3-MB with endothelial cells promotes tumor stem-cell growth, with the endothelial cells adopting an immature phenotype.
