School of Medicine Publications

Objectives

Aging involves significant changes in body composition, marked by declines in muscle mass and bone mineral density alongside an increase in fat mass. Sarcopenia is characterized by low strength and muscle mass, and osteosarcopenia is the coexistence of sarcopenia and osteopenia/osteoporosis. Physiologically, there is a crosstalk between muscle and bone tissues mediated by several pathways. Both, sarcopenia and osteosarcopenia, have been related with adverse outcomes such as functional disability. However, there is a lack of longitudinal studies. Therefore, this study aimed to assess whether sarcopenia and osteosarcopenia phenotypes increased the risk of functional disability in a longitudinal cohort of …

School of Medicine Publications

Granulomatosis with polyangiitis (GPA) is a necrotizing vasculitides subset of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAVs) that involves small-sized arteries affecting multisystemic organs. Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammatory polyarthritis involving the small joints. GPA and RA can have overlapping clinical presentations, including vasculitis, ocular inflammation, interstitial lung disease, and arthritis, but existing evidence indicates they are distinct conditions. Vasculitis-induced biologic tumor necrosis factor (TNF) inhibitors have been reported, particularly cutaneous vasculitis and lupus-like syndromes. We retrospectively review a case of a patient with rheumatoid arthritis with a newly diagnosed GPA with RA on anti-TNF …

Simple Summary

Pancreatic cancer (PanCa) is one of the deadliest forms of cancer with limited therapeutic options. The available conventional therapies are highly toxic and often show resistance. Accumulating evidence suggests that dysregulated ribosome biogenesis has been linked to the survival and aggressive phenotypes of many tumor types, including PanCa. Thus, targeting ribosome biogenesis could be a novel approach for suppressing the growth of PanCa. The current study aimed to investigate the anti-cancer efficacy and underlying molecular mechanisms of honey against PanCa. Our results demonstrated that honey induces apoptosis and inhibits the growth and invasive potential of PanCa cells by …

School of Medicine Publications

The role of rare non-coding variation in complex human phenotypes is still largely unknown. To elucidate the impact of rare variants in regulatory elements, we performed a whole-genome sequencing association analysis for height using 333,100 individuals from three datasets: UK Biobank (N = 200,003), TOPMed (N = 87,652) and All of Us (N = 45,445). We performed rare ( < 0.1% minor-allele-frequency) single-variant and aggregate testing of non-coding variants in regulatory regions based on proximal-regulatory, intergenic-regulatory and deep-intronic annotation. We observed 29 independent variants associated with height at P <  after conditioning on previously reported variants, with effect sizes ranging from −7cm to +4.7 cm. We also identified and replicated non-coding aggregate-based associations proximal to HMGA1 containing variants associated with a 5 cm taller height and of highly-conserved variants in MIR497HG on chromosome 17. We have developed an approach for identifying non-coding rare variants in regulatory regions with large effects from whole-genome sequencing data associated with complex traits.

Topological Cluster Statistic (Tcs): Toward Structural Connectivity–Guided Fmri Cluster Enhancement, Sina Mansour L., Caio Seguin, Anderson M. Winkler, Stephanie Noble, Andrew Zalesky

School of Medicine Publications

Abstract

Functional magnetic resonance imaging (fMRI) studies most commonly use cluster-based inference to detect local changes in brain activity. Insufficient statistical power and disproportionate false-positive rates reportedly hinder optimal inference. We propose a structural connectivity–guided clustering framework, called topological cluster statistic (TCS), that enhances sensitivity by leveraging white matter anatomical connectivity information. TCS harnesses multimodal information from diffusion tractography and functional imaging to improve task fMRI activation inference. Compared to conventional approaches, TCS consistently improves power over a wide range of effects. This improvement results in a 10%–50% increase in local sensitivity with the greatest gains for medium-sized effects. TCS …
