In Situ Conversion of Atherosclerotic Plaques' Iron into Nanotheranostics.

The presence of a substantial necrotic core in atherosclerotic plaques markedly heightens the risk of rupture, a consequence of elevated iron levels that exacerbate oxidative stress and lipid peroxidation, thereby sustaining a detrimental cycle of ferroptosis and inflammation. Concurrently targeting both ferroptosis and inflammation is crucial for the effective treatment of vulnerable plaques. In this study, we introduce gallium hexacyanoferrate nanoabsorption catalysts (GaHCF NACs) designed to disrupt this pathological cycle.

In this study, we prepared a porous scaffold made of polycaprolactone (PCL) and carbon quantum dots (CQDs), Fe, and Chitosan (Cs) as the scaffold core to cover the skin. Then evaluated antibacterial, biocompatibility, and wound healing properties as well as the expression of genes effective in wound healing.

Fish is a significant source of animal protein for humans; however, it has a tendency to bioaccumulate toxicants from the environment. The present study assessed the health risks associated with potential toxic metals (PTMs) in differently processed catfish (Clarias gariepinus) from four markets in Abeokuta metropolis, southwestern Nigeria. A total of 60 samples were collected and analyzed for PTMs using an Atomic Absorption Spectrophotometer.

A 16-year-old boy was diagnosed from multiple sclerosis (MS) after suffering from paresthesia in upper limbs and VI cranial nerve paresis. Corticosteroids and fingolimod were started. After 13 months a worsening of liver biochemical tests (LBT) was noticed: ALP 787 U/L, GGT 737 U/L, AST 195, ALT 321, Bi 0.

Hematoxylin and eosin (H&E) staining is a suitable approach for detecting substantial structural changes in neural tissues but is less sensitive for identifying subtle alterations to subcellular structures and various chemical constituents, including myelin. Neurohistological methods to better evaluate myelin integrity by light microscopy include acidophilic dyes (eg, eriochrome cyanine R, toluidine blue [used with hard plastic sections]); lipoprotein-binding dyes (eg, Luxol fast blue [LFB], Weil's iron hematoxylin); lipid impregnation with metals (eg, Marchi's, which uses osmium tetroxide for en bloc staining before embedding); and immunohistochemical (IHC) methods to highlight various antigens (eg, myelin basic protein [MBP] and peripheral myelin protein 22 [PMP22]). Some IHC methods reveal enhanced marker expression in damaged myelin (eg, matrix metalloproteinase-9 [MMP9], S100).
