The authors suggest to use iron hematoxylin according to Haidenhain's prescription, with the subsequent passage of stained and differentiated histological sections through the ammonia solution for detection of A-cells in the pancreatic islets. The A-cells cytoplasm stained dark blue intensively; as to the nuclear structures--they acquired bluish-black tints. The method can be used for the study of morphology, topography and the number of A-cells in the islets.

Background: Sepsis-induced acute lung injury (ALI) is a severe clinical condition accompanied with high mortality. Tangeretin, which is widely found in citrus fruits, has been reported to exert antioxidant and anti-inflammatory properties. However, whether tangeretin protects against sepsis-induced ALI and the potential mechanisms remain unclear.

Intravascular hemolysis releases hemoglobin (Hb) from red blood cells under specific conditions, yet the effect of hemolysis in aquaculture systems remain poorly understood. In this study, a continuous hemolysis model for grass carp was established by injection of phenylhydrazine (PHZ) to investigate the mechanistic impacts of sustained hemolysis. PHZ-induced hemolysis altered liver color, and subsequent hematoxylin and eosin staining revealed substantial Hb accumulation in the head kidney, accompanied by inflammatory cell infiltration and vacuolization in liver tissue.

Purpose: Myocardial ischemia/reperfusion injury (MIRI) is closely associated with ferroptosis. Dexmedetomidine (Dex) has good therapeutic effects on MIRI. This study investigates whether dexmedetomidine (Dex) regulates ferroptosis during MIRI by affecting ferroportin1 (FPN) levels and elucidates the underlying mechanisms.

This study aimed to elucidate the protective roles of Immune Response Gene-1 (IRG1) and exogenous itaconate in murine models of hepatic fibrosis and to delineate the underlying mechanistic pathways using both wild-type and IRG1-deficient (IRG1) mice. Primary murine stellate cells (mHSC) and bone marrow-derived macrophages (BMDM) were isolated and cocultured. Hepatocellular fibrosis was induced in vitro using Transforming Growth Factor-beta (TGF-β) to evaluate the protective efficacy of IRG1/itaconate.
