Biomimetic polydopamine loaded with janus kinase inhibitor for synergistic vitiligo therapy via hydrogel microneedles.

Background: Both oxidative stress and autoimmune responses play crucial roles in the development of vitiligo. Under oxidative stress, the apoptotic melanocytes expose self-antigens and release high mobility group box 1 (HMGB1), triggering autoimmune activation and recruiting CD8 T cells. This process further leads to the destruction of melanocytes, resulting in the lack of melanin granules.

Lipidomic profiling reveals the protective mechanism of nitrogen-controlled atmosphere on brown rice quality during storage.

Rice, a globally important staple, requires effective preservation methods to maintain its quality during extended storage. This study explored the efficacy of nitrogen-controlled atmosphere (NCA) storage in preserving the quality of brown rice during a one-year period using UHPLC-MS/MS based lipidomic profiling. A total of 1013 lipids were identified and categorized into five main groups.

Interleukin-1 Receptor-Associated Kinase-3 Aggravates Neuroinflammatory Injury After Intracerebral Hemorrhage via Activation NF-κB/IL-17A Pathway in Mice.

Background: Neuroinflammatory reactions are crucial factors in secondary brain damage following intracerebral hemorrhage (ICH). Although previous studies have shown that IRAK3 is involved in immune responses, the potential effects of IRAK3 on ICH remain unclear.

Methods: Collagenase IV-induced ICH mouse model.

Lysyl oxidase-like 2 promotes the survival, migration, and ferroptosis of endometrial cancer cells by activating the phosphoinositide 3-kinase/protein kinase B pathway.

Objectives: LOXL2, known as Lysyl oxidase-like 2, is classified as a lysyl oxidase (LOX) family member. However, its role and mechanism in endometrial cancer (EC) are unknown. Therefore, we aimed to investigate the potential role and mechanism of LOXL2 in EC.
