Inhibition of CD36 ameliorates mouse spinal cord injury by accelerating microglial lipophagy.

Spinal cord injury (SCI) is a serious trauma of the central nervous system (CNS). SCI induces a unique lipid-dense environment that results in the deposition of large amounts of lipid droplets (LDs). The presence of LDs has been shown to contribute to the progression of other diseases.

Polymeric Polylactic Acid-Glycolic Acid-Based Nanoparticles Deliver Nintedanib Across the Blood-Brain Barrier to Inhibit Glioblastoma Growth.

The aim of this study was to investigate the inhibitory effect of nintedanib (BIBF) on glioblastoma (GBM) cells and its mechanism of action and to optimize a drug delivery strategy to overcome the limitations posed by the blood-brain barrier (BBB). We analyzed the inhibition of GBM cell lines following BIBF treatment and explored its effect on the autophagy pathway. The cytotoxicity of BIBF was assessed using the CCK-8 assay, and further techniques such as transmission electron microscopy, Western blotting (WB), and flow cytometry were employed to demonstrate that BIBF could block the autophagic pathway by inhibiting the fusion of autophagosomes and lysosomes, ultimately limiting the proliferation of GBM cells.

Differential transcriptomic profiling of lipid metabolism and collagen remodeling in fast- and slow-twitch skeletal muscles in aging.

Skeletal muscle function gradually declines with aging, presenting substantial health and societal challenges. Comparative analysis of how aging affects fast- and slow-twitch muscles remains lacking. We utilized 20-month-old mice to reveal the aging effects on muscle structure and fiber composition, followed by bulk RNA sequencing for fast- and slow-twitch muscles and integration with human single-cell RNA sequencing dataset providing a comparative analysis across species.

Rare-Earth Pretreatment Improves Performance of Reactive Dye Argazol Navy Blue on Banana-Fiber Fabric.

At present, the use of conventional reactive dyes on banana-fiber fabric leads to the problem of excessive salt consumption, which is not conducive to environmental protection. In this experimental study, rare-earth-pretreated banana-fiber fabric was dyed with the reactive dye Argazol Navy Blue. The rare-earth pretreatment was carried out to reduce the level of salt consumption, improve dyeing and fixation rates, and reduce the treatment burden of printing and dyeing wastewater.
