Photonics Research 2024年第8期12卷 1587-1592页

The recent emergence of thin-film lithium niobate(TFLN) has extended the landscape of integrated *** has been enabled by the commercialization of TFLN wafers and advanced nanofabrication of TFLN such as high-quality dry etching. However, fabrication imperfections still limit the propagation loss to a few dB/m, restricting the impact of this platform. Here, we demonstrate TFLN microresonators with a record-high intrinsic quality(Q) factor of twenty-nine million, corresponding to an ultra-low propagation loss of 1.3 dB/m. We present spectral analysis and the statistical distribution of Q factors across different resonator geometries. Our work pushes the fabrication limits of TFLN photonics to achieve a Q factor within 1 order of magnitude of the material limit. ? 2024 Chinese Laser Press

Hematopoietic tumors are associated with diagnostic and therapeutic challenges and a poor prognosis. Furthermore, their pathophysiology in dogs is not well understood. Chronic lymphocytic leukemia has been rarely reported in golden retrievers, perhaps due to difficulties in diagnosis and care. An 8-year-old spayed female golden retriever was referred to our hospital with a 2-month history of fatigue, weakness, and selective appetite. The dog was diagnosed with chronic lymphocytic leukemia based on blood smear evaluation. Despite treatment, the dog deteriorated and the owners opted for euthanasia. Histopathological examination revealed atypical lymphocytes in the spleen, extramedullary hematopoiesis in the spleen and liver, bone marrow depletion, moderate neutrophilic myocarditis, and acute renal tubular necrosis. In an immunohistochemical panel, cells in the spleen and bone marrow were positive for anti-CD20, anti-CD45, anti-CD3, anti-IBA-1, anti-Ki67, anti-MUM-1, and anti-PAX-5. In conclusion, the leukemia diagnosis was confirmed through reactive histiocytosis, marked extramedullary hematopoiesis, and other clinical and laboratory findings. Herein, we report a case of chronic lymphocytic leukemia in a female dog with clinical, laboratory, and necroscopy findings.

灰盖鬼伞中过表达的碱性真菌漆酶在高盐染料废水中的应用潜力

引用

微生物学报 2024年第8期64卷 3014-3029页

【目的】本研究利用双孢菇(Agaricus bisporus)gpdII启动子,实现了碱性真菌漆酶PIE5(CcPIE5)在灰盖鬼伞(Coprinopsis cinerea)FA2222中的同源过表达。【方法】在mKjalke液体培养基中37℃培养7 d,漆酶活力达到(24.2±1.1)U/mL。纯化的CcPIE5在pH 8.0和60℃下表现出最佳催化活性。【结果】与已经研究报道的真菌漆酶不同,CcPIE5能耐受高浓度NaCl,当NaCl浓度从0升至1.5 mol/L时,CcPIE5的k_(cat)和K_(m)均呈下降趋势,表示CcPIE5在纺织印染废水脱色中有潜在应用价值。进一步在染料废水脱色应用中,以丁香酸作为介体,CcPIE5在pH 8.5和60℃条件下可高效降解(92.9±2.3)%的靛蓝胭脂红。通过LC-MS分析确认,Isatin 5-sulfonic acid(ISA)是靛蓝胭脂红降解的主要副产物。【结论】CcPIE5在高温、碱性和含盐条件下高效脱色染料,是处理环境和工业特定应用的理想选择。
