jck多囊肾小鼠肾囊泡上皮细胞MAPK信号通路上调

open access: yesZhongguo shiyan zhenduanxue, 2012
目的通过研究MAPK信号通路在多囊肾囊泡上皮细胞的调控,探讨多囊肾病的发病机制。方法以常染色体隐性遗传病jck多囊肾小鼠为模型,采用Western印迹法评价MAPK信号通路在jck多囊肾小鼠肾脏的表达和磷酸化调控。结果 jck多囊肾小鼠肾囊泡上皮细胞MAPK信号通路蛋白H-Ras、p-Raf、p-MEK、pERK、c-fos水平上调。结论 MAPK信号通路参与jck多囊肾小鼠肾囊泡的发生发展,提示MAPK通路可作为治疗多囊肾病的药物靶点。

Microwave‐Actuated CuS/CuCo2O4 Heterojunction Microneedles for Synergistic Eradication of Deep‐Seated Biofilms and Inflammatory Microenvironment Remodeling in Acne Treatment

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Deep skin infections and dense biofilm barriers caused by Propionibacterium acnes (P. acnes) remain significant challenges in recurrent acne vulgaris, exacerbated by the poor stratum corneum penetration of conventional therapies and rising antibiotic resistance.

交通信号的一种控制模型研究

open access: yes四川大学学报. 自然科学版, 2002
针对智能交通系统基础理论之一的路口交通信号控制问题,以典型"+"字路口为例,提出了更能概括路口多入多出情况的交通信号矩阵控制模型,该模型能反映交通信号的各种实际控制策略,模型参量具有明确的实际意义.在此模型基础上,分析了路口车辆流入量与流出量、车辆流出量与交通信号控制的关系,在避免路口发生碰撞的前提下,得到了路口的优化控制方案.

The vesicle trafficking R‐SNARE VAMP714 connects auxin responses, ROS and ion homeostasis in Arabidopsis under salt stress

open access: yesNew Phytologist, Volume 251, Issue 1, Page 207-227, July 2026.
Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.

3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

早产儿视网膜病变治疗药物研究进展

open access: yes浙江大学学报. 医学版
早产儿视网膜病变(ROP)是威胁早产儿视力的视网膜血管增殖性疾病。多种新型药物通过靶向与血管内皮生长因子(VEGF)相关信号通路[如PI3K/Akt、低氧诱导因子(HIF)-1α/VEGF等]、氧化应激、肿瘤坏死因子(TNF)-α和Notch等信号通路在ROP的治疗中展现出潜力。普萘洛尔、胰岛素样生长因子-1、塞来昔布通过PI3K/Akt信号通路减少病理性新生血管生成;雷公藤红素、褪黑素通过HIF-1α/VEGF信号通路抑制视网膜病变;脂联素通过增强内皮型一氧化氮合酶活性缓解氧化应激损伤 ...

Ultrathin MnO2‐PEG‐PD‐L1 Nanosheets Enable Tumor Microenvironment Modulation and NIR‐II Photothermal Immunotherapy for Durable Control of Lung Cancer and Postoperative Recurrence

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

Titanium Implant Abutments With Polydopamine‐Mesoporous Cerium Dioxide Coatings for Enhanced Antibacterial, Anti‐Inflammatory, and Soft Tissue Integration Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
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.
