In vivo FAP-CAR macrophages enhance chemotherapy and immunotherapy against pancreatic cancer by removing the fibrosis barrier.

Patients with pancreatic ductal adenocarcinoma (PDAC) derive limited benefits from chemotherapy or immunotherapy, with a five-year survival rate still below 10 %. The key therapeutic challenge is the dense fibrosis barrier driven by activated cancer-associated fibroblasts (CAFs) and their secreted collagen, which impedes drug penetration and characterizes PDAC as an immune-desert tumor. To address this challenge, we developed in vivo chimeric antigen receptor macrophages (FAP-CAR-M) targeting fibroblast activation protein-α (FAP), the marker of activated CAFs, to enhance chemo and immunotherapy against PDAC by removing the fibrosis barrier using mannose-modified mRNA-LNP (MLNP).

The composite abrasives with the structure of SiO@CeO@PDA have been fabricated in a simple manner and thoroughly characterized using scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.

Ultrafast deconstruction and reconstruction of corn starch via synergistic effect of high-frequency electric field and water motion.

The intricate multi-level microstructure of starch, formed through extensive inter- and intra-molecular hydrogen bonds, significantly influences the processability and performance of starch-based products. Consequently, the ability to effectively manipulate the multi-level microstructure holds substantial implications for the development of biomass products. This study introduces a novel approach utilizing high-frequency electric field (HFE) to produce a transparent and robust starch product.

Visualization Experiments of Nanoparticle-Surfactant-Stabilized Foam Flooding in Cores with Different Permeabilities by NMR.

Nanoparticle-stabilized foams can overcome the problem that conventional foams are easy to defoam in complex reservoirs, thereby losing foam function and seriously affecting foam profile control and flooding effect. However, the oil displacement characteristics and effects of the nanoparticle-stabilized foam in cores with different permeabilities directly determine its application prospects. The nuclear magnetic resonance (NMR) visualization technology was combined with the traditional foam displacement method in this paper, with the nanoparticle-stabilized foam system and oil as the displacement medium and the displaced medium, respectively, and the core as the carrier to physically simulate the process of the nanoparticle-stabilized foam flooding oil.

Management of an impacted maxillary central incisor with dilacerated root.

Dilaceration is a comparatively uncommon dental deformity generally characterized by an angulation between crown and root, and consequently causing non-eruption of the tooth. Dilaceration generally occurs following trauma to the apices of deciduous dentition, which lies close to the permanent tooth buds. As a result, surgical extraction used to be the first choice when making the treatment plan for a case with severely dilacerated teeth.
