Research on a Concentration Detection Method for Turbid Media Based on Multipath Combination.

In order to improve the accuracy of concentration detection in turbid media, this study proposes a solution concentration detection method based on a variable-angle wedge-shaped sample cell. Each angle of the wedge-shaped sample cell corresponds to a specific optical path combination. By measuring at multiple wedge angles, we can expand a variety of optical path combinations, providing more information about the turbid media.

Realizing High Thermoelectric Performance in ZnCl-Doped N-Type Polycrystalline SnSe Through Band Engineering and Incorporating Multiple Defects.

SnSe-based compounds, as promising thermoelectric materials, are well-known for their intrinsically low thermal conductivity and outstanding thermoelectric performance. However, the suboptimal electrical transport capacity for n-type polycrystalline SnSe significantly hinders the improvement of its thermoelectric performance. In this work, an effective approach for enhancing the thermoelectric performance of n-type SnSe polycrystalline materials through ZnCl doping has been investigated.

The spatiotemporal transcriptional profiling of murine brain during cerebral malaria progression and after artemisinin treatment.

Cerebral malaria (CM) is a severe encephalopathy caused by Plasmodium parasite infection, resulting in thousands of annual deaths and neuro-cognitive sequelae even after anti-malarial drugs treatment. Despite efforts to dissect the mechanism, the cellular transcriptomic reprogramming within the spatial context remains elusive. Here, we constructed single-cell and spatial transcriptome atlases of experimental CM (ECM) male murine brain tissues with or without artesunate (ART) treatment.

Multimodal lung cancer theranostics via manganese phosphate/quercetin particle.

The diagnosis and treatment of non-small cell lung cancer in clinical settings face serious challenges, particularly due to the lack of integration between the two processes, which limit real-time adjustments in treatment plans based on the patient's condition and drive-up treatment costs. Here, we present a multifunctional pH-sensitive core-shell nanoparticle containing quercetin (QCT), termed AHA@MnP/QCT NPs, designed for the simultaneous diagnosis and treatment of non-small cell lung cancer. Mechanistic studies indicated that QCT and Mn exhibited excellent peroxidase-like (POD-like) activity, catalysing the conversion of endogenous hydrogen peroxide into highly toxic hydroxyl radicals through a Fenton-like reaction, depleting glutathione (GSH), promoting reactive oxygen species (ROS) generation in mitochondria and endoplasmic reticulum, and inducing ferroptosis.

Thermoelectric Properties of a Light Compound FeS: the Role of Electron Correlation Strengthened Spin-Orbital Coupling.

Spin-orbit coupling (SOC) induced nontrivial bandgap and complex Fermi surface has been considered to be profitable for thermoelectrics, which, however, is generally appreciable only in heavy elements, thereby detrimental to practical application. In this study, the SOC-driven extraordinary thermoelectric performance in a light 2D material Fe₂S₂ is demonstrated via first-principles calculations. The abnormally strong SOC, induced by electron correlation through 3d orbitals polarization, significantly renormalizes the band structures, which opens the bandgap via Fe 3d orbitals inversion, exposes the second conduction valley with weak electron-phonon coupling, and aligns the energy of Fe 3d and S 3p orbitals with divergent momentum in valence band.

VRAC channel inhibition as a novel strategy for the treatment of ischemia-reperfusion injury.

Ischemia-reperfusion injury is a serious clinical pathology involving multiple organs such as the heart and brain. The injury results from oxidative stress, inflammatory response and cell death triggered by restoring tissue blood flow after ischemia, leading to severe cell and tissue damage. In recent years, the volume-regulated anion channel (VRAC) has gained attention as an important membrane protein complex.

Single-drug Chemotherapy Plus Immunotherapy as First-line Treatment for Stage Ⅳ Non-small Cell Lung Cancer Elderly Patients: A Phase II Clinical Trial UNICORN Study.

Introduction: Lung cancer remains the most common malignancy and the leading cancer-related death among the elderly in China, which deserves more research attention. Immunotherapy combined with platinum-based doublet chemotherapy has been approved as the standard treatment for advanced non-small cell lung cancer (NSCLC) patients who are devoid of specific gene mutations or fusions. Given that patients with NSCLC over the age of 65 typically exhibit declining organ function and physical condition, they often showed reduced tolerance for this rigorous treatment regimen.

Evaluation of Radiotherapy Efficacy and Prognostic Analysis for Solid and Cystic Brain Metastases.

Objectives: Brain metastases (BMs) are commonly categorized into cystic and solid. However, the difference in the prognosis of patients with either cystic or solid BMs following radiotherapy remains poorly understood. We used a retrospective design to elucidate the disparities in survival between these two patient groups undergoing radiotherapy and to identify factors influencing the overall survival (OS) of patients with BMs.

Photoaffinity probe-based antimalarial target identification of artemisinin in the intraerythrocytic developmental cycle of .

Malaria continues to pose a serious global health threat, and artemisinin remains the core drug for global malaria control. However, the situation of malaria resistance has become increasingly severe due to the emergence and spread of artemisinin resistance. In recent years, significant progress has been made in understanding the mechanism of action (MoA) of artemisinin.

Large-Scale Synthesis of High-Loading Single Metallic Atom Catalysts by a Metal Coordination Route.

Single atom catalyst (SAC) is one of the most efficient and versatile catalysts with well-defined active sites. However, its facile and large-scale preparation, the prerequisite of industrial applications, has been very challenging. This dilemma originates from the Gibbs-Thomson effect, which renders it rather difficult to achieve high single atom loading (< 3 mol%).

CHST12: a potential prognostic biomarker related to the immunotherapy response in pancreatic adenocarcinoma.

Background: Pancreatic adenocarcinoma (PAAD) is characterized by lower immunogenicity with a poor response rate to immune checkpoint inhibitors (ICIs) and exhibits the poorest prognosis of all solid tumors, which results in the highest tumor-related mortality among malignancies. However, the underlying mechanisms are poorly understood. In addition, diverse carbohydrate sulfotransferases (CHSTs), which are involved in the sulfation process of these structures, play an important role in the metastatic spread of tumor cells.
