There are three distinct genetic systems in higher plants,the dominant nuclear genome and the semi-autonomous organelle genomes(plastids and mitochondria).In contrast to the conserved plastid genome(plastome),the plant mitochondrial genome(mitogenome)is characterized by an intriguing“evolutionary paradox”distinguished by a remarkably low mutation rate but with a significantly high rearrangement rate(Palmer and Herbon,1988;Lai et al.,2022).

Paragangliomas,also known as pheochromocytomas(1–9 cases per million),arise in the paraganglia.[1]Pheochromocytomas occur in the adrenal glands,while paragangliomas occur elsewhere.[2]Paragangliomas originate from paraganglion cells,which are derived from the neural ectoderm of the nerves and migrate along both sides of the median axis from the base of the skull to the pelvis during embryonic development.

Light-Activated Virtual Sensor Array with Machine Learning for Non-Invasive Diagnosis of Coronary Heart Disease

Nano-Micro Letters 2024年第12期 435-456页

作者： Jiawang Hu hao Qian Sanyang han Ping Zhang Yuan Lu Department of Chemical Engineering Tsinghua University Key Laboratory of Industrial Biocatalysis Ministry of Education Tsinghua University Department of Cardiology Xuanwu Hospital Capital Medical University Department of Cardiology Beijing Tsinghua Changgung Hospital School of Clinical Medicine Tsinghua University Institute of Biopharmaceutical and Health Engineering Shenzhen International Graduate School Tsinghua University

Early non-invasive diagnosis of coronary heart disease（CHD） is critical. However, it is challenging to achieve accurate CHD diagnosis via detecting breath. In this work, heterostructured complexes of black phosphorus（BP） and two-dimensional carbide and nitride（MXene） with high gas sensitivity and photo responsiveness were formulated using a self-assembly strategy. A light-activated virtual sensor array（LAVSA） based on BP/Ti3C2Txwas prepared under photomodulation and further assembled into an instant gas sensing platform（IGSP）. In addition, a machine learning（ML） algorithm was introduced to help the IGSP detect and recognize the signals of breath samples to diagnose CHD. Due to the synergistic effect of BP and Ti3C2Txas well as photo excitation, the synthesized heterostructured complexes exhibited higher performance than pristine Ti3C2Tx, with a response value 26% higher than that of pristine Ti3C2Tx. In addition, with the help of a pattern recognition algorithm, LAVSA successfully detected and identified 15 odor molecules affiliated with alcohols, ketones, aldehydes, esters, and acids. Meanwhile, with the assistance of ML, the IGSP achieved 69.2% accuracy in detecting the breath odor of 45 volunteers from healthy people and CHD patients. In conclusion, an immediate, low-cost, and accurate prototype was designed and fabricated for the noninvasive diagnosis of CHD, which provided a generalized solution for diagnosing other diseases and other more complex application scenarios.

Chemodynamic therapy(CDT),an inventive approach to cancer treatment,exploits innate chemical processes to trigger cell death through the generation of reactive oxygen species(ROS).While offering advantages over conventional treatments,the optimization of CDT efficacy presents challenges stemming from suboptimal catalytic efficiency and the counteractive ROS scavenging effect of intracellular glutathione(GSH).In this study,we aim to address this dual challenge by delving into the role of copper valence states in *** the unique attributes of copper-based nanoparticles,especially zero-valent copper nanoparticles(CuPd NPs),we aim to enhance the therapeutic potential of *** experiments reveal that zero-valent CuPd NPs outperform divalent copper nanoparticles(Ox-CuPd NPs)by displaying superior catalytic performance and sustaining ROS generation through a dual approach integrating peroxidase-like(POD-like)activity and Cu+***,zero-valent NPs exhibit enhanced GSH depletion compared to their divalent counterparts,thereby intensifying CDT and inducing ferroptosis,ultimately resulting in high-efficiency tumor growth *** findings reveal the impact of valences on CDT,providing novel insights for the optimization and design of CDT agents.
