Assessment of collagen birefringence in different grades of oral squamous cell carcinoma using Picrosirius red - polarizing microscopy and comparison with Picrosirius red - Fast green stain. [PDF]
J Oral Maxillofac PatholBackground: Oral squamous cell carcinoma (OSCC) is among the most common cancers globally, with significant prevalence in India. While OSCC is primarily an epithelial malignancy, its interaction with the surrounding stroma influences tumour progression.

Reexploring picrosirius red: A review
Indian Journal of Pathology and Oncology, 2020 Picrosirius red stain has been increasingly used for collagen studies in dental and medical research. Sirius red is an acidic dye which binds specifically to collagen and distinguishes type I and type III collagen fibres. This review depicts earlier uses of picric acid, preparation of the picrosirus red stain, mechanism of action, hazards and safety ...

Hepatology, EarlyView., 2022 Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Hepatology, EarlyView., 2022 Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Collagen in the scarless fetal skin wound: Detection with Picrosirius-polarization [PDF]
Wound Repair and Regeneration, 2005 Our group has developed an ovine model of deep dermal, partial-thickness burn where the fetus heals scarlessly and the lamb heals with scar. The comparison of collagen structure between these two different mechanisms of healing may elucidate the process of scarless wound healing.

Postoperative pancreatic fistula affects recurrence-free survival of pancreatic cancer patients.
PLoS ONE, 2021 PurposePostoperative pancreatic fistula (POPF) with reported incidence rates up to 45% contributes substantially to overall morbidity. In this study, we conducted a retrospective evaluation of POPF along with its potential perioperative clinical risk ...
