Obesity is characterized by an excess of energy-storing white fat. An ingenious and sought-after strategy against obesity is to activate energy-consuming beige fat, which is converted from white fat or brown fat. However, existing tools for assessing brown or beige fat activation in vivo have certain limitations, such as being cumbersome and expensive. Optical imaging is a relatively straightforward and economical imaging technique that utilizes light to peer into the structural–functional information of living organisms at multiple scales. Despite the availability of various optical imaging modalities for detecting brown or beige fat, there is a dearth of literature summarizing relevant studies. Accordingly, this review focuses on these optical modalities and elaborates on their imaging principles, characteristics, and recent research advances in the detection of brown or beige fat. Their imaging targets, advantages, and disadvantages are further concluded. As a methodological reference, this review can guide the selection of optimal optical modalities to noninvasively profile brown or beige fat activation from a specific biological perspective, maximizing the potential of optical imaging in anti-obesity assessment.","PeriodicalId":34127,"journal":{"name":"VIEW","volume":"6 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is essential for patients with cardiovascular disease to receive an early diagnosis of AMI. The most popular technique for the early detection of AMI is the use of biosensors to monitor the concentration of pertinent biomarkers, such as cardiac troponin I (cTnI), in the blood. The electrochemical detection methods hold great promise because of their simplicity, miniaturization, ease of integration, high sensitivity, and rapid response. The prime motive of this review is to present a comprehensive understanding of the pros and cons of methodologies employed for the electrochemical approaches toward the detection of cTnI. A detailed summary is provided for the immunosensors, aptamer sensors, molecular imprinting sensors, and peptide sensors based on various affinity elements. We enumerate the modified electrode materials for electrochemical sensors as well as popular detection techniques. Furthermore, this paper reviews some recent significant advances in point-of-care assays for rapid, accurate detection of cTnI as a smart integrated device for home monitoring. The accumulation of knowledge about these functions will lead to new insights into and concepts for the design of portable miniature sensors for cardiovascular patients at risk of AMI.

This capability further helps to design fluorescent labels with lower phototoxicity and drugs with better efficacy. Conventional ways to evaluate cellular phototoxicity rely on late-stage measurements of individual or different populations of cells. Here, we developed a quantitative method using intracellular microtubule polymerization as a rapid and sensitive marker to quantify early-stage phototoxicity. Implementing this method, we assessed the photosensitization induced by organelle dyes illuminated with different excitation wavelengths. Notably, fluorescent markers targeting mitochondria, nuclei, and endoplasmic reticulum exhibited diverse levels of phototoxicity. Furthermore, leveraging a real-time precision opto-control technology allowed us to evaluate the synergistic effect of light and dyes on specific organelles. Studies in hypoxia revealed enhanced phototoxicity of Mito-Tracker Red CMXRos that is not correlated with the generation of reactive oxygen species but a different deleterious pathway in low oxygen conditions.","PeriodicalId":34127,"journal":{"name":"VIEW","volume":"11 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complex microenvironments, including hyperglycemia, bacterial infection, ischemia, and nerve damage, lead to the prolonged inflammation and proliferation phase of diabetic wounds. Mesenchymal stem cell-derived small extracellular vesicles (MSC-sEVs), which contain a rich variety of therapeutic molecules, have been chased for decades because of their potential roles in cellular communication, tissue regeneration, and drug delivery. As powerful tools for the controlled-sustained release of sEVs, biocompatible hydrogels have been applied in a wide range of biomedical applications. Herein, we first summarize the pathological features of diabetic wounds, such as angiopathy, neuropathy, and immune cell dysfunction. Then, we discuss the biological properties, therapeutic performance, and stability of pure MSC-sEVs. After that, we discuss the components, application patterns, and responsiveness of hydrogels. Next, we discuss the loading avenues of MSC-sEVs into hydrogel, the release behaviors of sEVs from hydrogels, and the influence of the crosslinking method on the hydrogel-sEV composites. Finally, we provide an overview of the current applications of hydrogels loaded with MSC-sEVs as a novel cell-free tissue engineering system in managing diabetic wounds and propose the critical unsolved issues. This review is expected to provide meaningful guidance for developing a novel cell-free tissue engineering system for diabetic wound management.","PeriodicalId":34127,"journal":{"name":"VIEW","volume":"46 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obesity is a common risk factor for OA. Chondrocyte autophagy plays a crucial role in delaying the onset of OA. Our previous studies have demonstrated a significant elevation in the levels of oleic acid (OLA) and linoleic acid (LA) in the synovial fluid (SF) of patients with OA and obesity compared to those with OA alone, and an inhibitory effect of these molecules on the activation of autophagy. Accumulating evidence indicates a reciprocal regulatory relationship between autophagy and ciliogenesis; however, whether autophagy-mediated ciliogenesis plays a significant role in the pathogenesis of OA remains unclear. In this study, we aimed to determine whether OLA and LA affect OA development via the regulation of chondrocyte autophagy-mediated ciliogenesis. We found that both molecules inhibited this process in chondrocytes. Moreover, intracellular calcium and reactive oxygen species (ROS) levels increased simultaneously. Further, we explored the relationship between autophagy and ciliogenesis in chondrocytes. Activation of autophagy by rapamycin significantly attenuated the ciliogenesis inhibition caused by OLA and LA. Importantly, the downregulation of AKT and mTOR expression in chondrocytes reversed the autophagy-mediated inhibition of ciliogenesis and the ROS-accumulation-mediated inflammation induced by OLA and LA. Taken together, our results suggest that OLA and LA induce calcium-overload-driven ROS accumulation via autophagy-mediated ciliogenic disorders during OA pathogenesis. These findings demonstrate that targeting autophagy and ciliogenesis in chondrocytes is a protective strategy in the OA pathogenesis induced by OLA and LA.","PeriodicalId":34127,"journal":{"name":"VIEW","volume":"26 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the development of lasers, ultrasonic detectors, and data computations, PAT has been widely applied for the diagnosis of oncology, dermatosis, etc. However, the energy of light and ultrasound would be greatly attenuated while penetrating the skull, due to the reflection, absorption, and scattering effects, resulting in limited application of PAT in brain imaging. In this review, we summarized the achievements of PAT and its application in the detection of brain diseases including glioma, stroke, traumatic brain injury, Alzheimer's disease, epilepsy, and Parkinson's disease.

These innovative electrodes not only incorporate 3D printed personalized materials but also eliminate the need for electrolyte gel, which tends to dehydrate over time. Additionally, these electrodes boast unique attributes such as stretchability, deformability, biocompatibility, wearable comfort, and cost-effective manufacturing. While the advantages of dry electrodes are apparent, their performance optimization encounters challenges related to charge migration, particularly when scaled down to miniaturized dimensions, impacting biosignal detection. This study addresses these challenges by focusing on the development of scalable, stretchable, and highly deformable syringe-printed dry electrocardiogram (ECG) patches. The approach employs straightforward multi-material direct-ink-writing (DIW) techniques, realizing complete biopatches per print, resulting in a rapid and cost-effective fabrication process. The achieved printing resolution reaches up to 200 µm, and the conductivity of Ag/AgCl dry electrodes reaches approximately ∼ 5 × 10<sup>4</sup> S/m. This not only ensures scalability but also expands the applications of metal-based inks to various soft electronic devices, particularly in low-resource settings and environments.","PeriodicalId":34127,"journal":{"name":"VIEW","volume":"50 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141532230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
