GM-CSF and IL-21-armed oncolytic vaccinia virus significantly enhances anti-tumor activity and synergizes with anti-PD1 immunotherapy in pancreatic cancer.

Pancreatic cancer is one of the most aggressive cancers and poses significant challenges to current therapies because of its complex immunosuppressive tumor microenvironment (TME). Oncolytic viruses armed with immunoregulatory molecules are promising strategies to overcome limited efficacy and target inaccessible and metastatic tumors. In this study, we constructed a tumor-selective vaccinia virus (VV) with deletions of the TK and A49 genes (VVLΔTKΔA49, VVL-DD) using CRISPR-Cas9-based homologous recombination.

SiO-based inorganic nanofiber aerogel with rapid hemostasis and liver wound healing functions.

Non-compressible hemostasis and promoting tissue healing are important in soft tissue trauma repair. Inorganic aerogels show superior performance in rapid hemostasis or promoting tissue healing, but simultaneously promoting non-compressive hemostasis and soft tissue healing still remains a challenge. Herein, SiO-based inorganic nanofiber aerogels (M@SiO, M=Ca, Mg, and Sr) were prepared by freeze-drying the mixture of bioactive silicates-deposited SiO nanofibers and SiO sol.

Simultaneously Achieved High Piezoelectricity and High Resistivity in NaBiTiO-Based Ceramics with High Curie Temperature.

Good piezoelectricity and high resistivity are prerequisites for high-temperature acceleration sensors to function correctly in high-temperature environments. Bismuth layered structure ferroelectrics (BLSFs) are promising candidates for piezoelectric ceramics with excellent piezoelectric performance at high temperatures, high electrical resistivity, and high Curie temperatures (). In this study, (LiMn) is substituted for Bi at the A-site, and Ce-doping is performed to replace Ti ions in NaBiTiO, which achieves the desired combination of high piezoelectric coefficients and high resistivity.

Nutrient Content Prediction and Geographical Origin Identification of Bananas by Combining Hyperspectral Imaging with Chemometrics.

The nutritional quality of bananas and their geographical origin authenticity are very important for trade. There is an urgent need for rapid, non-destructive testing to improve the origin and quality assurance for importers, distributors, and consumers. In this study, 99 banana samples from a range of producing countries were collected.
