CRISPR/Cas9-engineered universal CD123/B7-H3 tandem CAR-T cell for the treatment of acute myeloid leukemia.

Background: Autologous chimeric antigen receptor T (CAR-T) cell therapy has demonstrated efficacy in the treatment of acute myeloid leukemia (AML). Nevertheless, the intrinsic characteristics of autologous therapy, such as extended manufacturing timelines and patient-specific limitations, contribute to delays in treatment availability. More critically, relapse due to antigen escape following single-targeted CAR-T therapy constitutes a significant clinical obstacle.

Zero-valent iron-promoted vivianite formation via dissimilatory iron reduction: Role of humic acid.

Vivianite, as a high-value phosphorus (P) recovery product, has attracted extensive attention. However, previous studies have indicated that the Fe/P ratio and extracellular electron transfer (EET) efficiency may be factors influencing dissimilatory iron reduction (DIR) for vivianite formation. This study investigated the role of zero-valent iron (ZVI) in vivianite formation and elucidated the impact of humic acid (HA) during this process.

Preclinical and clinical evaluation of intratumoral injection of an IL-12 expressing SKV-012 oncolytic virus for advanced solid tumors.

Methods: We evaluated SKV-012's safety and efficacy in preclinical models.

CBSNet: An Effective Method for Potato Leaf Disease Classification.

As potato is an important crop, potato disease detection and classification are of key significance in guaranteeing food security and enhancing agricultural production efficiency. Aiming at the problems of tiny spots, blurred disease edges, and susceptibility to noise interference during image acquisition and transmission in potato leaf diseases, we propose a CBSNet-based potato disease recognition method. Firstly, a convolution module called Channel Reconstruction Multi-Scale Convolution (CRMC) is designed to extract the upper and lower features by separating the channel features and applying a more optimized convolution to the upper and lower features, followed by a multi-scale convolution operation to capture the key changes more effectively.

A semi-supervised boundary segmentation network for remote sensing images.

Accurately segmenting remote sensing images remains challenging due to the diverse target scales and ambiguous structural boundaries. In this work, we propose a semi-supervised boundary segmentation network (BS-GAN) to address these challenges. BS-GAN employs a semi-supervised learning approach to reduce dependency on labeled data while introducing a novel mixed attention (MA) mechanism to enhance segmentation accuracy by aggregating long-range contextual information.

Development and Characterization of a Lysosome-Targeting SLC3A2/PD-L1 Bispecific Antibody-Drug Conjugate for Enhanced Antitumor Efficacy in Solid Tumors.

Bispecific antibodies (BsAb) and antibody-drug conjugates (ADC) have shown significant promise in cancer treatment, enhancing drug selectivity and therapeutic efficacy as demonstrated in multiple clinical studies. Bispecific antibody-drug conjugates (BsADC), which combine the targeting capabilities of BsAbs with the cytotoxic potential of ADCs, offer a novel approach to overcoming several challenges associated with ADCs, including limited internalization, off-target toxicity, and drug resistance. In this study, we identified solute carrier family 3 member 2 (SLC3A2) as a highly expressed protein in a variety of solid tumors, making it a promising therapeutic target.

mRNA-Engineered CD5-CAR-γδT Cells for the Immunotherapy of T-Cell Acute Lymphoblastic Leukemia.

Clinical trials of Chimeric Antigen Receptor T-cell (CAR-T) therapy have demonstrated remarkable success in treating both solid tumors and hematological malignancies. Nanobodies (Nbs) have emerged as promising antigen-targeting domains for CARs, owing to their high specificity, robust stability, and strong affinity, leading to significant advancements in the field of Nb-CAR-T. In the realm of T-cell acute lymphoblastic leukemia (T-ALL) targets, CD5 stands out as a potentially excellent candidate for T-cell-based CAR therapy, due to its distinct expression on the surface of malignant T-ALL cells.

Imaging-based body fat distribution and diabetic retinopathy in general US population with diabetes: an NHANES analysis (2003-2006 and 2011-2018).

Background: Limited studies have investigated the correlation between fat distribution and the risk of diabetic retinopathy (DR) in the general population with diabetes. The relationship between obesity and DR remains inconclusive, possibly due to using simple anthropometric measures to define obesity. This study investigates the relationships between the android-to-gynoid fat ratio (A/G ratio, measured using dual-energy X-ray absorptiometry) and DR within the US population with diabetes.

Systemic delivery of oncolytic herpes virus using CAR-T cells enhances targeting of antitumor immuno-virotherapy.

Recent studies have indicated that combining oncolytic viruses with CAR-T cells in therapy has shown superior anti-tumor effects, representing a promising approach. Nonetheless, the localized delivery method of intratumoral injection poses challenges for treating metastatic tumors or distal tumors that are difficult to reach. To address this obstacle, we employed HSV-1-infected CAR-T cells, which systemically delivery HSV into solid tumors.

Delivery of CD47-SIRPα checkpoint blocker by BCMA-directed UCAR-T cells enhances antitumor efficacy in multiple myeloma.

In the treatment of relapsed or refractory multiple myeloma patients, BCMA-directed autologous CAR-T cells have showed excellent anti-tumor activity. However, their widespread application is limited due to the arguably cost and time-consuming. Multiple myeloma cells highly expressed CD47 molecule and interact with the SIRPα ligand on the surface of macrophages, in which evade the clearance of macrophages through the activation of "don't eat me" signal.

Revealing the response of community structure and metabolic pathway to varying organic matter stress in a dissolved oxygen-differentiated airlift internal circulation partial nitritation-anammox system.

In practice, the influent organic matter is often pre-treated to reduce the impact on partial nitritation-anammox (PNA) process. However, the influent organics may also drive the denitrification process and improve total nitrogen removal efficiency of the PNA process. Thus, we designed and operated a novel dissolved oxygen-differentiated airlift internal circulation PNA (PNA-DOAIC) system in this study at various influent C/N ratios of 0-4.

Background: Chimeric antigen receptor (CAR) T cells and immune checkpoint blockades (ICBs) have made remarkable breakthroughs in cancer treatment, but the efficacy is still limited for solid tumors due to tumor antigen heterogeneity and the tumor immune microenvironment. The restrained treatment efficacy prompted us to seek new potential therapeutic methods.

Methods: In this study, we conducted a small molecule compound library screen in a human BC cell line to identify whether certain drugs contribute to CAR T cell killing.

Contributions of MOF-808 to methane production from anaerobic digestion of waste activated sludge.

The bioconversion of waste activated sludge (WAS) into methane is usually limited by the poor hydrolysis of sludge and/or poor syntrophic methanogenesis during anaerobic digestion (AD). In this study, the underlying mechanism of MOF-808 enhancing hydrolysis and syntrophic methanogenesis during AD process of WAS was investigated. Experimentally, with the effects of MOF-808 (150 mg MOF-808/g Volatile Solid (VS)), the methane production and the proportion of methane in biogas increased by approximately 26.
