Indian Journal of Dental Research, 2019 Introduction: Collagen forms an integral part of connective tissue and maintains its structural integrity. It has natural birefringence which is attributed to the arrangement of its fibers and is enhanced by special stains such as picrosirius red through

The polarization colors of picrosirius red-stained collagen in systemic sclerosis.
Nishi Nihon Hifuka, 1991 全身性鞏皮症における真皮膠原線維の変化を知るために, Picrosirius red染色標本を偏光顕微鏡にて観察した。皮膚片は15例の全身性鞏皮症患者(浮腫∼硬化期2例, 硬化期11例, 萎縮期2例)の前腕伸側から得られた。また, 健康人27例より得た材料を対照とした。その結果, 健康人では年齢, 性, 部位にかかわりなく同じ橙色偏光を示した。これに対し鞏皮症にあつては, 病期と関係なしにすべて緑色偏光を示すのが観察された。一部についておこなわれた電顕的観察では, 鞏皮症における膠原線維の直径は, 健康人のそれに比較して小さいのが認められた。これらより偏光の違いには膠原線維の直径が関与し, そしてこの方法が鞏皮症の病理組織学的診断に有用であることが示唆される。

Diagnosis of Collagen Type III Glomerulopathy Using Picrosirius Red and PASH/Masson’s Trichrome Stain [PDF]
Veterinary Pathology, 2020 Canine collagen type III glomerulopathy (Col3GP) is a rare juvenile nephropathy in which irregular type III collagen fibrils and fibronectin accumulate in glomerular capillary walls and the mesangium. Necropsy findings were reviewed from 5 puppies diagnosed with Col3GP at 6 to 18 weeks of age.

G3BP1 Succinylation at K413 is Critical for Cardiac Function by Modulating PI3K‐AKT‐mTOR Signal Axis
Advanced Science, EarlyView.Schematic illustrating the impact of G3BP1 succinylation at K413 on cardiac function. In the healthy human heart, G3BP1 succinylation maintains homeostatic mTOR signaling. In patients with dilated cardiomyopathy (DCM) and heart failure (HF), G3BP1 de‐succinylation induces RagA expression and disrupts the binding of the TSC1/2 complex, leading to the ...

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair
Advanced Science, EarlyView.A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular
