The "Protein synthesis Using Recombinant Elements" ("PURE") system is a minimal biochemical system capable of carrying out cell-free protein synthesis using defined enzymatic components. This study extends PURE by integrating an ATP regeneration system based on pyruvate oxidase, acetate kinase, and catalase. The new pathway generates acetyl phosphate from pyruvate, phosphate, and oxygen, which is used to rephosphorylate ATP .

This review explores how RES modulates mitophagy-the selective autophagic degradation of mitochondria essential for maintaining cellular homeostasis. RES promotes the initiation and execution of mitophagy by enhancing PINK1/Parkin-mediated mitochondrial clearance, reducing reactive oxygen species production, and mitigating apoptosis, thereby preserving mitochondrial integrity.

Chronic/heavy exposure with ethanol is associated with risk of type 2 diabetes, due to β-cells dysfunction. It has been reported that ethanol can induce oxidative stress directly or indirectly by involvement of mitochondria. We aimed to explore the protective effects of the crocin/gallic acid/L-alliin as natural antioxidants separately on ethanol-induced mitochondrial damage.

Donafenib is an improved version of sorafenib in which deuterium is substituted into the drug's chemical structure, enhancing its stability and antitumor activity. Donafenib exhibits enhanced antitumor activity and better tolerance than sorafenib in preclinical and clinical studies. However, the specific mechanism of its effect on hepatocellular carcinoma has not been reported.

Smart packaging, also known as intelligent packaging, is responsive to external stimuli, moisture, light, oxygen, heat, pH, and bacterial growth. In this study, polyvinyl alcohol/nanochitosan/phycocyanin nanocomposite (PVA/NCH/PC-NC) for fish fillets of Oncorhynchus mykiss rainbow trout coating was prepared. Five treatments were prepared over a period of 14 days (0, 1, 7 and 14 days) under treatments of T: fish coated with PVA/NCH-NC without PC; T, T T and T fish coated with PVA/NCH/PC-NC (0.
