Identification of a novel fibroblast growth factor receptor-agonistic peptide and its effect on diabetic wound healing.

Aims: Fibroblast growth factor (FGF) is a broad class of secretory chemicals that act via FGF receptors (FGFR). The study aims to explore the role of a novel peptide, FAP1 (FGFR-agonistic peptide 1), in tissue regeneration and repair. It investigates whether FAP1 mimics basic fibroblast growth factor (bFGF) and accelerates wound healing both in vitro and in vivo.

Impact of glucocorticoids on the therapeutic efficacy of denosumab against osteoporosis in patients with rheumatoid arthritis.

Background: Rheumatoid arthritis (RA) and prolonged high-dose glucocorticoid (GC) treatment are established risk factors for osteoporosis.

Objectives: In this study, we aimed to evaluate the therapeutic efficacy of denosumab according to the GC dose considered to increase the risk of glucocorticoid-induced osteoporosis (GIOP) in patients with RA.

Design: A retrospective analysis of collected data on RA patients with osteoporosis starting denosumab.

Prognostic Value of Coronary Angiography-Derived Index of Microcirculatory Resistance in Patients With Intermediate Coronary Stenosis.

Background: The association between coronary microcirculation and clinical outcomes in patients with intermediate stenosis remains unclear.

Objectives: The aim of this study was to assess the prognostic significance of angiography-derived index of microcirculatory resistance (angio-IMR) in patients with intermediate coronary stenosis.

Methods: This post hoc analysis included 1,658 patients from the FLAVOUR (Fractional Flow Reserve and Intravascular Ultrasound for Clinical Outcomes in Patients with Intermediate Stenosis) trial, with angio-IMR measured in each vessel exhibiting intermediate stenosis.

A hyperelastic torque-reversal mechanism for soft joints with compression-responsive transient bistability.

Snap-through, a rapid transition of a system from an equilibrium state to a nonadjacent equilibrium state, is a valuable design element of soft devices for converting a monolithic stimulus into systematic responses with impulsive motions. A common way to benefit from snap-through is to embody it within structures and materials, such as bistable structures. Torque-reversal mechanisms discovered in nature, which harness snap-through instability via muscular forces, may have comparative advantages.

Upregulation of interferon-γ response genes in monocytes and T cells identified by single-cell transcriptomics in patients with anti-citrullinated peptide antibody-positive early rheumatoid arthritis.

Introduction: Our aim was to investigate the insufficiently understood differences in the immune system between anti-citrullinated peptide antibody (ACPA)-positive (ACPA) and ACPA-negative (ACPA) early rheumatoid arthritis (eRA) patients.

Methods: We performed multiple cytokine assays using sera from drug-naïve ACPA and ACPA eRA patients. Additionally, we conducted single-cell RNA sequencing of CD45 cells from peripheral blood samples to analyze and compare the distribution and functional characteristics of the cell subsets based on the ACPA status.
