An Organo‐Pt(II) Photosensitizer With Robust Photo‐Assisted Antibacterial and Wound Recovery Performances in Diabetic Mice Wound Model

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The pathogenesis of diabetic foot ulcers is complex, often involving polymicrobial infection and persistent inflammatory responses, which lead to delayed or nonhealing wounds, posing a formidable clinical challenge. Existing photodynamic therapy reagents and traditional treatments generally address only a single pathological aspect, and the ...

Large Cation‐Induced Lattice Distortion in Carbon‐Based High‐Entropy Oxides: Spin‐State Engineering and Broadband Microwave Absorption

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

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.

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

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 ...

局部亚低温治疗对高血压性脑出血患者血清hs-CRP及Hcy水平的影响研究

open access: yesZhongguo shiyan zhenduanxue, 2020
目的探讨局部亚低温治疗对高血压性脑出血患者血清hs-CRP及Hcy水平的影响。方法将2016年7月至2018年7月期间我院的40例高血压脑出血患者按照随机数字表法分为对照组与试验组,各为20例。两组患者均给予脱水降颅压、控制血压、调节水电解质、酸碱平衡、防止并发症的发生、脑保护等基本药物治疗。在此基础上,实验组患者给予头颅亚低温治疗。比较两组患者治疗前后简易智力状态检查量表(MMSE)评分、神经功能缺损量表(NIHSS)评分、血清超敏-C反应蛋白(hs-CRP)与同型半胱氨酸(Hcy)水平 ...

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.

Changing trends in prenatal screening and treatment of cytomegalovirus infection in France: 7‐year national cohort study (2017–2023)

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 756-763, June 2026.
ABSTRACT Objectives Cytomegalovirus (CMV) is the leading cause of congenital infectious neurosensory impairment. We aimed to present national epidemiological data on maternal CMV infection during pregnancy in France, focusing in particular on primary infection in the periconceptional period or first trimester, and to assess the impact of changes in ...

18F-FDG PET/CT在肿瘤治疗耐受区域寻找方面的应用

open access: yesZhongguo shiyan zhenduanxue, 2020
肿瘤患者经过放疗、治疗后,肿瘤内耐受治疗的瘤体部分仍会存活下来,这是肿瘤的复发或者转移的主要原因之一。如果能够在治疗前确定肿瘤内具有治疗耐受的区域,并给予针对性的治疗,将获得更好的治疗效果,减少肿瘤复发或者转移的机率。另外,通过分析治疗后肿瘤残存部分代谢的活性,可以明确治疗后仍具有活性的肿瘤部分,对肿瘤再次治疗方案精准制定具有其它方法无法比拟的优势。为了这些目的,本研究采用18 F-FDG PET/CT影像相关指标做为衡量标准用于评价肿瘤治疗前后不同区域代谢的变化 ...
