Summary: We developed a novel copolymer-based porous carbon microfiber (PCMF) through wet-spinning, which greatly enhances electrochemical detection. By wet spinning a copolymer solution of PAN and PMMA, we successfully synthesized controllable porous carbon microfibers with increased edge-plane character. The increase in porosity improves the surface disorder, leading to significantly improved electrochemical detection capabilities.

Summary: A novel, unique, mercury-free, and user-friendly voltammetric sensor of Ni(II) based on glassy carbon electrode modified with zeolite(MOR)/graphite(G)/dimethylglyoxime(DMG) composite (MOR/G/DMG-GCE) was fabricated and applied for highly selective, ultra-trace determination of nickel ions. The chemically active MOR/G/DMG nanocomposite enabled the selective and effective accumulation of Ni(II) ions as the DMG-Ni(II) complex. The developed protocol showed linear response in the concentration range of 0.86-19.61 μg L-1 and 0.57-15.75 μg L-1 for accumulation times of 30 s and 60 s, respectively, with a limit of detection of 0.18 μg L-1 (3.04 nM) and sensitivity of 0.202 μA L μg-1.

Summary: This study investigates the presence of melatonin biosynthesizing enzyme genes in the zebrafish gut and their daily mRNA expression profile under different feeding regimes. The results show opposite phase in the daily mRNA expression of certain genes in altered feeding conditions compared to regular feeding conditions, while core clock genes display rhythmic expression patterns in the gut regardless of feeding schedule. Changes in the rhythmic expression of biosynthesizing enzyme genes through feeding may lead to desynchronization in fish physiology.

Summary: This study compared the effects of isoflurane and xylazine on a mouse model of MCAo. The results showed that the isoflurane group had slightly improved survival rate, brain infarct volume, and neurological deficits after 24 hours of reperfusion injury. However, the xylazine group showed similar results to the control group. Therefore, combining isoflurane and xylazine anesthesia can reduce the risk of mortality and establish a predictable MCAo model.
