The Lupus Damage Index Revision Program: Results From the Item Generation and Reduction Phases

Arthritis Care &Research, EarlyView.
Objective A data‐driven and expert/patient consensus‐based project to develop a revised Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI) is under way supported by SLICC, ACR, and the Lupus Foundation of America. Our objective is to report the item generation and reduction phase results

Troponin-I is not falsely elevated in asymptomatic dialysis patients

Saudi Journal of Kidney Diseases and Transplantation, 2013
Dialysis patients with troponin-I levels above the cut-off value diagnostic for acute myocardial event (AME) are sometimes labeled as having "renal cause" of elevated troponin-I.

Clinical Characteristics and Concordance of Anti‐MDA5 Antibodies: A Multicenter Australian Study

Arthritis Care &Research, EarlyView.
Objective In Australia, anti‐MDA5 antibodies are exclusively tested by a line immunoblot assay (LIA). The clinical concordance of an LIA‐positive anti‐MDA5 result is unclear. We aimed to describe the clinical features and determine the clinical concordance of patients with anti‐MDA5 antibodies. Methods Electronic records of a multisite cohort (patients

Computational Studies of Cardiac and Skeletal Troponin

Frontiers in Molecular Biosciences, 2019
Troponin is a key regulatory protein in muscle contraction, consisting of three subunits troponin C (TnC), troponin I (TnI), and troponin T (TnT). Calcium association to TnC initiates contraction by causing a series of dynamic and conformational changes ...

Recombinant nanobodies detecting the human cardiac troponin proteins by ELISA

Antibody Reports, 2023
We tested the capacity of antibodies RB733, RB734, RB766, RB767, RB768, RB769, RB770, RB771, RB772 and RB773 to recognize by ELISA three different molecular forms of the human cardiac troponin T isoform 6 (cTnT): an N-terminal peptide (Nter-cTnT), the ...

Contractile effects of the exchange of cardiac troponin for fast skeletal troponin in rabbit psoas single myofibrils [PDF]

, 2003
The effects of the removal of fast skeletal troponin C (fsTnC) and its replacement by cardiac troponin C (cTnC) and the exchange of fast skeletal troponin (fsTn) for cardiac troponin (cTn) were measured in rabbit fast skeletal myofibrils. Electrophoretic

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

In Vivo Monitoring of Thrombo‐Inflammatory Biomarkers via Molecularly Imprinted Polymer‐Integrated Hydrogel Microneedles

Advanced Materials, EarlyView.
A wearable electrochemical microneedle patch integrates Prussian Blue redox transduction with molecularly imprinted polymer recognition for reagent‐free sampling and detection of thrombo‐inflammatory biomarkers in dermal interstitial fluid. The platform tracks thrombin and inflammatory cytokines with sensitive in vitro, ex vivo, and in vivo performance,

Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

Advanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

Impact of copeptin on diagnosis of acute coronary syndrome

Egyptian Journal of Medical Human Genetics, 2014
Background: Acute coronary syndrome remains the principal cause of death, so the early diagnosis is of great importance. Cardiac troponin is the preferred biomarker for acute myocardial infarction.
