Scavenger receptor class A member 3 (SR-A3) is implicated in metabolic diseases; however, the relationship between SR-A3 and metabolic dysfunction-associated fatty liver disease (MAFLD) has not been documented. Here, we show that hepatic SR-A3 expression is significantly reduced in human and animal models in the context of MAFLD. Genetic inhibition of SR-A3 in hamsters elicits hyperlipidemia, hyperglycemia, insulin resistance, and hepatic steatosis under chow-diet condition, yet escalates in diet-induced MAFLD.

Optical diffraction tomography (ODT) is an important technique for three-dimensional (3D) imaging of semi-transparent biological samples, enabling volumetric visualization of living cells, cultures, and tissues without the need for exogenous dyes. However, ODT faces significant challenges in imaging complex biological specimens due to the limited specificity of refractive index (RI) and the coupled relationship between absorption and phase in image formation. Here, we present multi-modal transport of intensity diffraction tomography (MM-TIDT), a high-speed 3D microscopy technique that integrates an electrically tunable lens with modified illumination patterns to decouple phase and absorption information.

T cell receptor-engineered T (TCR-T) cell therapies are at the forefront of cancer immunotherapy, offering a transformative approach that significantly enhances the ability of T cells to recognize and eliminate cancer cells. This innovative method involves genetically modifying TCRs to increase their affinity for tumor-specific antigens. While these enhancements improve the ability of T cells to recognize and bind to antigens on cancer cells, rigorous assessment of specificity remains crucial to ensure safety and targeted responses.

Oxyanion groups recently offer an innovative avenue for improving the sluggish kinetics of electrochemical reactions benefitting from their particular polyanion configurations and large electronegativity. Nevertheless, the exact structure design and deep regulating mechanism of oxyanion species remain poorly understood. Herein, a fresh architecture of the sulfate oxyanion coordinated nickel-iron nanoalloy on nitrogen and sulfur co-doped carbon nanotube (SO -NiFe/NSCT) is newly proposed to study the activity increment effect and mechanism.

The induction of immunogenic cell death (ICD) can activate antitumor immune response to potentiate cancer immunotherapy. In this study, we observed the antitumor activity following combinatorial therapy with anti-CTLA4 antibody and epigallocatechin-3-gallate (EGCG) in CT26 tumors.Indeed, EGCG triggered colon cancer cells ICD with the secretion of high-mobility group protein B1 (HMGB1) and the surface expression of calreticulin (CRT) and heat shock protein 70 (HSP70).

CD8 T cells are integral to the effective management of cancer and infectious diseases due to their cytotoxic functions. The efficacy of these cells is profoundly influenced by their metabolic state, which regulates their activation, differentiation, and longevity. Accordingly, the modulation of metabolic pathways within CD8 T cells is crucial for enhancing the effectiveness of T cell-based immunotherapy.

Segmentation of the fetal and maternal structures, particularly intrapartum ultrasound imaging as advocated by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) for monitoring labor progression, is a crucial first step for quantitative diagnosis and clinical decision-making. This requires specialized analysis by obstetrics professionals, in a task that i) is highly time- and cost-consuming and ii) often yields inconsistent results. The utility of automatic segmentation algorithms for biometry has been proven, though existing results remain suboptimal.

High-voltage P2-NaNiMnO layered oxide cathode exhibits significant potential for sodium-ion batteries, owing to the elevated operating voltage and theoretical energy density beyond lithium iron phosphate, but the large-volume phase transition is the devil. Currently, this type cathode still suffers from stability-capacity trade-off dilemma. Herein, a concept of customized strategy via multiple rock-forming elements trace doping is presented to address the mentioned issue.

is a soil-borne pathogen that poses a serious threat to the quality and yield of hundreds of crops worldwide, particularly tobacco production. Using metabolomics technology, we investigated natural metabolites from disease-conducting soil (DCS) and disease-suppressing soil (DSS) of tobacco rhizosphere as fungicides to control tobacco Fusarium wilt (TFW), which is mainly caused by . Furthermore, the antifungal mechanisms of these natural metabolites were preliminarily elucidated through various assessments, including antifungal activity determination, chemotaxis effect tests, PI staining experiments, and measurements of extracellular conductivity and protein content.

Fluorine (F) and Cadmium (Cd) have given rise to public concern regarding their adverse impacts on the environment and human beings. Yet, the toxic interplay between F and Cd on the intestine is still vague. Aiming to investigate the role of F on Cd-damaged intestine, a total of five groups of 30 SD rats were picked at random to be gavaged for 90 days: Control group (Ultra-pure water), Cd (Cd 1 mg/kg), Cd+LF (Cd 1 mg/kg+F 15 mg/kg), Cd+MF (Cd 1 mg/kg+F 45 mg/kg), and Cd+HF (Cd 1 mg/kg+F 75 mg/kg).

Dental pulp stem cells (DPSCs) are responsible for maintaining pulp structure and function after pulp injury. DPSCs migrate directionally to the injury site before differentiating into odontoblast-like cells, which is a prerequisite and a determinant in pulp repair. Increasing evidence suggests that sensory neuron-stem cell crosstalk is critical for maintaining normal physiological functions, and sensory nerves influence stem cells mainly by neuropeptides.

[4-(3,6-dimethyl-9H-carbazol-9yl)butyl]phosphonic acid (Me-4PACz) self-assembly material has been recognized as a highly effective approach for mitigating nickel oxide (NiO) surface-related challenges in inverted perovskite solar cells (IPSCs). However, its uneven film generation and failure to effectively passivate the buried interface defects limit the device's performance improvement potential. Herein, p-xylylenediphosphonic acid (p-XPA) containing bilateral phosphate groups (-POH) is introduced as an interface layer between the NiO/Me-4PACz and the perovskite layer.

Article Synopsis
  • Cancer immunotherapies often fail in some patients because there's a lack of immune response, but dihydroartemisinin (DHA) has been found to induce a specific type of cell death that can trigger immune responses in liver cancer (HCC).
  • DHA works by inhibiting certain proteins called cyclin-dependent kinases (CDKs), which increases reactive oxygen species (ROS) in cells, leading to this immune-activating cell death.
  • In mouse studies, DHA not only increased the number of immune cells that attack tumors but also boosted the effectiveness of other cancer treatments like anti-PD-1 antibodies and CAR T-cell therapy, making it a promising treatment option for HCC patients.
