Microplastics（MPs） are a new type of emerging pollutant in the aquatic environment that pose a tremendous risk to aquatic organisms and human health. Although many studies have focused on the removal of MPs, most of the materials used are non-renewable, non-degradable, and relatively costly. The development of green, renewable,and cost-effective materials for the removal of MPs presents a significant challenge. In this work, cellulose nanofiber-coated, delignified wood（CNF-CDW） was prepared and used as an efficient filter to remove MPs for the first time. Balsa wood chip was delignified through three approaches using NaClO2, Na2SO3/NaOH, and a deep eutectic solvent（DES） consisting of choline chloride/lactic acid. Delignified wood（DW） with desirable mechanical properties and a high pore structure was successfully prepared by optimizing the delignification method and reaction conditions. Subsequently, the CNF-CDW was prepared through immersion of DW in a suspension of cellulose nanofiber（CNF）, followed by crosslinking with CaCl2solutions. The effects of CNF concentration, CaCl2concentration, and wood chip thickness on the removal efficiency and flux of CNF-CDW towards polystyrene（PS）MPs were systematically studied. Under the optimal conditions of 0.5 wt% CNF, 1 mol/L CaCl2, and 10 mm in thickness, the CNF-CDW exhibited superior MPs removal performance, with a removal efficiency of 95.97% and a flux of 1146 L/m2·h. Morphological analysis revealed that CNF formed compact films on the surface DW, and MPs were efficiently blocked both on the surface and internal cellular structure of CNF-CDW. Therefore, with its exceptional filtration efficiency, high flux, and sustainable nature, CNF-CDW has a broad application prospect in the field of removing MPs from aquatic environment, promoting a brighter and cleaner future for aquatic ecosystems and human well-being.

Studies have shown that C1q/tumor necrosis factor-related protein-6 (CTRP6) can alleviate renal ischemia/reperfusion injury in mice. However, its role in the brain remains poorly understood. To investigate the role of CTRP6 in cerebral ischemia/reperfusion injury associated with diabetes mellitus, a diabetes mellitus mouse model of cerebral ischemia/reperfusion injury was established by occlusion of the middle cerebral artery. To overexpress CTRP6 in the brain, an adeno-associated virus carrying CTRP6 was injected into the lateral ventricle. The result was that oxygen injury and inflammation in brain tissue were clearly attenuated, and the number of neurons was greatly reduced. In vitro experiments showed that CTRP6 knockout exacerbated oxidative damage, inflammatory reaction, and apoptosis in cerebral cortical neurons in high glucose hypoxia-simulated diabetic cerebral ischemia/reperfusion injury. CTRP6 overexpression enhanced the sirtuin-1 signaling pathway in diabetic brains after ischemia/reperfusion injury. To investigate the mechanism underlying these effects, we examined mice with depletion of brain tissue-specific sirtuin-1. CTRP6-like protection was achieved by activating the sirtuin-1 signaling pathway. Taken together, these results indicate that CTRP6 likely attenuates cerebral ischemia/reperfusion injury through activation of the sirtuin-1 signaling pathway.

In-situ dating of the zircons, titanites, and apatites in the rock fragments of approximately 1 cm2in size from the Acasta Gneiss Complex was performed using secondary ion mass spectrometry or laser ablation inductively coupled plasma mass spectrometry to provide constraints on the thermal history of the Acasta Gneiss Complex. The zircons in these rock fragments typically exhibit multiple age populations, reflecting the presence of inherited zircons or the post-crystallization process of zircon overgrowth. Combined with previous studies, our zircon dating results reveal multiple magmatic events that occurred in the Acasta Gneiss Complex, specifically at >3.96, ~3.72, and ~3.57 Ga, respectively. A titanite Pb-Pb isochron age of2911±22 Ma(95% confidence level, MSWD=1.5) for sample AY199 is identified, consistent with the timing of the latest Archean magmatism in the Acasta Gneiss Complex. The titanite U-Pb ages for samples AC478 and AY066 are 1932±270 Ma(95% confidence level, MSWD=2.3) and 1813±45 Ma(95% confidence level, MSWD=2.3), respectively. The apatites in sample P090803-C exhibit a Pb-Pb isochron age of 1833±26 Ma(95% confidence level, MSWD=1.4). The apatite U-Pb ages for samples AC478, AY199, and AY066 are 1850±20 Ma(95% confidence level, MSWD=1.3), 1827±100 Ma(95% confidence level, MSWD=6.3), and 1807±58 Ma(95% confidence level, MSWD=3.9), respectively. Titanites in samples AC478 and AY066, as well as the apatites in all four investigated samples, show a uniform age(Pb-Pb or U-Pb age) of ~1.9–1.8 Ga,indicating U-Pb system reset in these minerals due to the Wopmay orogeny and documenting that the peak temperature condition associated with the Wopmay orogeny exceeded the apatite U-Pb closure temperature and approached or exceeded that of titanite.
