Development of two-frequency planar doppler velocimetry instrumentation [PDF]

open access: yes, 2006
This thesis describes the development of the two-frequency Planar Doppler Velocimetry (2n-PDV) flow measurement technique. This is modification of the Planar Doppler Velocimetry (PDV) technique that allows the measurement of up to three components of ...

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Integrated Clinical and Proteomic Profiling of CD19 Chimeric Antigen Receptor T Cell Therapy in Progressive Systemic Sclerosis

open access: yesArthritis &Rheumatology, EarlyView.
Objective To characterize the clinical, immunologic, and proteomic changes associated with CD19 chimeric antigen receptor T cell therapy in patients with progressive systemic sclerosis (SSc). Methods Patients with progressive SSc received CD19 chimeric antigen receptor (CAR)‐T cell therapy and were observed longitudinally for safety, clinical efficacy,

ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

open access: yesHepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Technique for Lateral Opening Wedge Distal Femoral Osteotomy Using Patient‐Specific Instrumentation for Genu Valgum and Patellar Instability

open access: yesArthroscopy Techniques, EarlyView.
Abstract Recurrent lateral patellar instability poses a technical challenge to orthopaedic surgeons. Isolated soft‐tissue procedures through medial patellofemoral ligament reconstruction or lateral release show unacceptably high failure rates. Lateral opening wedge distal femoral osteotomy addresses underlying bony malalignment and reinforces the soft ...

Macrophage‐targeted cerium‐tannic acid metal‐polyphenol framework nanoenzyme promotes in situ heart valves regeneration through adaptive immunomodulation

open access: yesBMEMat, EarlyView.
A novel nanoenzyme based on cerium ions‐tannic acid metal‐polyphenol framework (FCT) has been developed and loaded onto DHVs for targeting M1 macrophages to reduce their ROS level and reprogram macrophage phenotype, thereby eliminating inflammation, promoting endothelialization and adaptive matrix remodeling of scaffolds, offering a promising strategy ...

Radial capacity and hemodynamics evaluation in vitro and implantable feasibility validation in vivo of thinner bioresorbable polymer vascular stents

open access: yesBMEMat, EarlyView.
A series of in vitro experiments, numerical simulations and in vivo experiments were conducted to jointly evaluate the effects of different thicknesses of bioabsorbable polymer vascular stents on their radial capacity, hemodynamics and in vivo outcomes.
