Quantitative Histopathology Analysis Based on Label-free Multiphoton Imaging for Breast Cancer Diagnosis and Neoadjuvant Immunotherapy Response Assessment.

Accurate diagnosis and assessment of breast cancer treatment responses are critical challenges in clinical practice, influencing patient treatment strategies and ultimately long-term prognosis. Currently, diagnosing breast cancer and evaluating the efficacy of neoadjuvant immunotherapy (NAIT) primarily rely on pathological identification of tumor cell morphology, count, and arrangement. However, when tumors are small, the tumors and tumor beds are difficult to detect; relying solely on tumor cell identification may lead to false negatives.

Q11, a CYP2E1 inhibitor, exerts anti-hepatocellular carcinoma effect by inhibiting M2 macrophage polarization.

Despite significant advancements in cancer immunotherapy, many patients continue to respond poorly. Novel therapeutic strategies and drugs are urgently needed. Here, we found that CYP2E1 is upregulated in M2 macrophages.

Cytochrome P450 2E1 inhibitor Q11 is effective on hepatocellular carcinoma by promoting peritumor neutrophil chemotaxis.

Current studies found that the peritumoral tissue of hepatocellular carcinoma (HCC) may be different from normal liver tissue based on proteomics, and related to progression, recurrence and metastasis of HCC. Our previous study proposed "peritumor microenvironment (PME)" to summarize the influence of peritumor tissue on occurrence and progression of HCC. Peritumor CYP2E1 activity was significantly elevated in HCC, and related to occurrence and progression of HCC.

UV-activated gas sensor based on ordered mesoporous ZnO-TiO heterogeneous composites for trace NO detection at room temperature.

The growing modern industry has promoted the development of gas sensors for environmental monitoring and safety checks. However, the traditional chemical resistance gas sensor still has some disadvantages such as high power consumption and limited detection, mainly due to the lack of charge transfer ability of sensing materials. In this paper, an ordered UV-activated gas sensor with mesoporous ZnO/TiO nanotube composite was prepared by precisely controlling the growth of ZnO on the inner wall of TiO nanotube.

Apoptotic body based biomimetic hybrid nanovesicles to attenuate cytokine storms for sepsis treatment.

Sepsis is a severe immune response to pathogens that is associated with high mortality rate and a paucity of efficacious treatment options. It is characterized by the hyperactivation of macrophages and the occurrence of cytokine storms. Given the anti-inflammatory properties of M2 macrophages and their derived apoptotic bodies (AB), as well as the specific uptake of these by macrophages, a novel approach was employed to combine AB with artificial liposomes to create apoptotic body based biomimetic hybrid nanovesicles (L-AB).

Advancing multiplexed ion monitoring techniques: The development of integrated thermally drawn polymer fiber-based ion probes.

The monitoring of ion homeostasis in vivo is of paramount importance due to its critical functions in biological systems. However, current leading technologies for creating ion-selective electrodes often fall short of the requirements for in vivo applications in terms of multiplexity, miniaturization, and flexibility. To address this gap, we introduce an integrated multiplexed ion monitoring probe created from thermally drawn multi-electrode polymer fiber, aimed at enhancing in vivo ion homeostasis studies.

Diagnosis of Fibrotic Interstitial Lung Diseases Based on the Combination of Label-Free Quantitative Multiphoton Fiber Histology and Machine Learning.

Interstitial lung disease (ILD), characterized by inflammation and fibrosis, often suffers from low diagnostic accuracy and consistency. Traditional hematoxylin and eosin (H&E) staining primarily reveals cellular inflammation with limited detail on fibrosis. To address these issues, we introduce a pioneering label-free quantitative multiphoton fiber histology (MPFH) technique that delineates the intricate characteristics of collagen and elastin fibers for ILD diagnosis.

Embracing Poisson Encapsulation Statistics for Improved Droplet Digital Immunoassay.

Digital immunoassays enable the detection of protein biomarkers with very low concentrations, but the analysis stringently requires single-bead encapsulation. Low bead density has been adopted to minimize multiple-bead encapsulations, but the trade-off is the low droplet effectiveness (∼10%) in droplet-based assays. Here we report the method of inclusive droplet digital ELISA (iddELISA) that embraces all types of encapsulations by factoring in their varied "on-off" probabilities in the statistical inference.

Comparative study of insulin resistance surrogate indices to predict mild cognitive impairment among Chinese non-diabetic adults.

Objective: The study aims to investigate the associations of triglyceride glucose (TyG), TyG combined with body mass index (TyG-BMI), metabolic score for insulin resistance (METS-IR), the triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C), and the risk of mild cognitive impairment (MCI) in individuals without diabetes aged 45 and above.

Endothelium-targeted NF-κB siRNA nanogel for magnetic resonance imaging and visualized-anti-inflammation treatment of atherosclerosis.

Atherosclerosis-induced lethal cardiovascular disease remains a severe healthcare threat due to the limited drug efficiency and untimely prediction of high-risk events caused by inadequate target specificity of medications, incapable recognition of insensitive patients, and variable morphology of vulnerable plaques. Therefore, it is necessary to develop efficient strategies to improve the diagnosis accuracy and achieve visualized treatment of atherosclerosis. Herein, we establish an inflamed endothelium-targeted three-in-one nucleic acid nanogel system that can reverse the inflammatory state of endothelial cells (ECs) in plaques and simultaneously achieve real-time monitoring of the therapy process for efficient atherosclerosis diagnosis and treatment.
