貉源大肠杆菌四环素耐药基因的检测

open access: yes野生动物学报, 2020
的:为了解黑龙江省和吉林省健康貉中大肠杆菌四环素耐药基因的分布情况,以貉源大肠杆菌为模板,检测四环素耐药基因,为控制耐药性奠定基础,有利于临床合理用药。方法:共选取56株貉大肠杆菌,通过PCR扩增靶基因以检测耐药基因的携带状态。 结果:四环素抗性基因tetM的检出率为82.14%,还检测到tetA、tetB、tetC、tetD,未检测出tetE。结论:大肠杆菌四环素耐药性可能由几种耐药基因共同介导。试验结果可为貉临床实践中合理使用四环素和预防四环素抗性出现提供理论依据。

Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.

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 ...

A Dual‐Function Mitochondria‐Targeted Polyoxometalate Nanomicelle Boosts Pyroptosis‐Dependent Antitumor Immune Response in Triple‐Negative Breast Cancer

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The efficacy of immunotherapy in triple‐negative breast cancer (TNBC) is often limited, whereas the immunotherapeutic potential of pyroptosis is frequently undermined by a compensatory surge in mitophagy. To address this challenge, this study developed a reactive oxygen species (ROS)‐responsive and mitochondria‐targeted nanomicelle (POM@CTT ...
