ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...

目的探讨下肢骨折病人D二聚体定量检测的临床价值。方法采用增强型乳胶免疫比浊法对109例下肢骨折患者术前、术后第3天及术后第7天进行血浆D二聚体的定量检测,跟踪观察患者病情。结果109例患者有10例并发DVT,并发DVT组术前、术后第3天及术后第7天血浆D二聚体的检测结果有显著性差异(P0.05)。而并发DVT组与未并发DVT组相比较:术前血浆D二聚体的检测结果无显著性差异(P>0.05);术后第3天血浆D二聚体的检测结果有显著性差异 ...

ABSTRACT Bone defect repair in elderly patients is frequently compromised by reduced osteogenic capacity and delayed healing. Chronic inflammation‐driven inflammaging is a critical contributor to this impairment, characterized by dysfunctional autophagy in senescent macrophages (S‐MΦs), excessive reactive oxygen species (ROS) accumulation, and ...

ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.

晚期结直肠癌患者DC-CIK免疫干预前后D二聚体改变的临床研究
目的探讨DC-CIK免疫干预前后晚期结直肠癌患者凝血功能及D二聚体的变化。方法选择DC-CIK免疫干预的40位晚期结直肠癌患者,在G-CSF动员前5天内及DC-CIK免疫干预1个月后行凝血功能及D二聚体的检测。选择健康成年人43例行凝血功能及D二聚体检测作为对照。比较DC-CIK免疫干预前、后及健康成年人的凝血功能及D二聚体的差异。结果20C-CIK免疫治疗后D二聚体明显降低(P=0.005),但仍明显高于健康成年人(P=0.03),FIB也明显下降但未显示统计学差异(P=0.067)。结论20DC ...

ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves
