As the need for energy storage devices escalates,aqueous zincion batteries(ZIBs)have risen as a promising alternative to the widely used Li-ion batteries,offering intrinsic safety,environmental compatibility,and cost advantages,positioning them as attractive energy storage systems for the future[1,2].However,challenges such as dendrite growth on Zn anodes,stemming from uneven electric fields on the surface and active water side reactions,compromise cycling stability and lifespan,posing significant hurdles for the practical application of ZIBs[3,4].To mitigate these issues,strategies like electrolyte optimization,artificial solid electrolyte interphase(SEI)layers,and current collector modifications have been proposed[5,6].Nevertheless,most long-cycle experiments are conducted at low current densities and deposition capacities,with high current density and capacity operations typically lasting less than 1000 h[7].

The leaflet architecture of Cyclocarya cf. paliurus （Batal.） Iljinskaja from the Hunchun Formation （Middle Eocene） shows similarity to that of modem C. paliurus （Batal.） Iljinskaja and the specimen is the oldest fossil record in Europe and Asia. The distributions of C. cf. paliurus and other fossil records, such as Glyptostrobus, Metasequoia, Nyssa, and Liquidambar, in Hunchun flora show that it would have been a warmer-temperature to subtropical climate in Hunchun District during the Eocene period.

虹鳟(Oncorhynchus mykiss)对低氧极为敏感，低氧胁迫下其抗氧化酶活性和细胞凋亡会受到影响。为了解不同浓度低氧胁迫对虹鳟心脏抗氧化和细胞凋亡的影响，本研究通过酶活性测定和qRT-PCR方法，检测了虹鳟心脏在重度(3.0±0.1 mg/L)和中度(4.5±0.1 mg/L)低氧胁迫下4、8、12、24 h、1月以及复氧(8.5±0.1 mg/L)后12和24 h抗氧化指标和凋亡基因表达的变化。结果显示，与对照组相比，重度低氧胁迫下总超氧化物歧化酶(total superoxide dismutase, T-SOD)和过氧化氢酶(catalases, CAT)活性在24 h和1月时显著降低(P<0.05)，丙二醛(malondialdehyde, MDA)含量在12 h显著升高(P<0.05)；中度低氧胁迫下TSOD、CAT、总抗氧化能力(total antioxidant capacity, T-AOC)活性呈升高趋势。总蛋白(total protein, TP)含量在重度和中度低氧胁迫1月后均显著降低(P<0.05)。与对照组相比，铜锌-SOD(Cu/Zn-SOD, cu/zn-sod)和锰-SOD(Mn-SOD, mn-sod)基因表达量在重度和中度低氧胁迫下均显著降低(P<0.05),cat表达量在重度低氧4、8和12 h显著降低(P<0.05)。凋亡抑制基因B细胞淋巴瘤-2(B-cell lymphoma-2, Bcl-2)表达量在短期低氧各时期显著升高(P<0.05),Bcl-2-associated X(Bax)表达量无显著变化，胱天蛋白酶3(caspase-3, casp3)和肿瘤抑制因子53(tumor suppressor gene 53, p53)表达量在12 h显著降低(P<0.05)。酸性磷酸酶(acid phosphatase, ACP)和碱性磷酸酶(alkaline phosphatase, AKP)含量在重度和中度低氧胁迫12 h均显著高于对照组(P<0.05)。以上结果表明，虹鳟心脏在不同浓度低氧环境下可以通过调节抗氧化酶活性和凋亡相关基因的表达来减少氧化损伤。本研究为进一步阐明低氧环境下虹鳟心脏的氧化应激机制提供依据。
