Mitochondrial transfer of drug-loaded artificial mitochondria for enhanced anti-Glioma therapy through synergistic apoptosis/ferroptosis/immunogenic cell death.

Mitochondrial targeting in gliomas represents a novel therapeutic strategy with significant potential to enhance drug sensitivity by effectively killing glioma cells at the mitochondrial level. In this study, we developed artificial mitochondria derived from mitochondrial membrane-based nanovesicles, enabling precise mitochondrial targeting of doxorubicin (Dox) to selectively eradicate cancer cells by amplifying multiple cell death pathways. It was found that Dox-encapsulating mitochondria-based nanovesicles (DOX-MitoNVs) exhibited an extraordinary ability to penetrate the blood-brain barrier (BBB), specifically targeting gliomas.

Sample Size Effects on Petrophysical Characterization and Fluid-to-Pore Accessibility of Natural Rocks.

Laboratory-scale analysis of natural rocks provides petrophysical properties such as density, porosity, pore diameter/pore-throat diameter distribution, and fluid accessibility, in addition to the size and shape of framework grains and their contact relationship with the rock matrix. Different types of laboratory approaches for petrophysical characterization involve the use of a range of sample sizes. While the sample sizes selected should aim to be representative of the rock body, there are inherent limitations imposed by the analytical principles and holding capacities of the different experimental apparatuses, with many instruments only able to accept samples at the μm-mm scale.

Tuning the Ferroelectric Phase Transition of P(VDF-TrFE) through a Simple Approach of Modification by Introducing Double Bonds.

Electroactive polymer (EAP) is a kind of intelligent material that, driven by external electric field, could produce changes in shape or volume. As an important class of EAP materials, poly(vinylidene fluoride) (PVDF) based relaxor ferroelectric polymers show remarkable potential for applications in sensors, actuator, and artificial muscles because of their excellent electrostrictive properties. However, the strain of PVDF-based relaxor ferroelectrics relies strongly on a high electric field, which seriously damages their reliability and limits their practical applications as wearable devices.

Pore types, genesis, and evolution model of lacustrine oil-prone shale: a case study of the Cretaceous Qingshankou Formation, Songliao Basin, NE China.

A comprehensive characterisation of the pore structure in shale oil reservoirs is essential for forecasting oil production and exploration risks. This study forecasted these risks in the oil-rich Songliao Basin using combination of high-resolution field emission scanning electron microscopy and quantitative X-ray diffraction to analyze the pore genesis and evolution mode within the first member of the Cretaceous Qingshankou Formation (Kqn). The results showed the dominance of inorganic pores over organic pores, wherein diagenetic processes, such as compaction, pressure solution, and cementation, were responsible for the destruction of pore structure in the formation.
