A Targeted Octahedral DNA Nanostructure Co-delivers siME3 and Doxorubicin to Enhance Collateral Lethality in ME2-Deficient Pancreatic Cancer.

The genetic characteristics of pancreatic cancer (PC) are being revealed, but treatment strategies based on these profiles are developing slowly. About one-third of PC patients harbor mutations, with its homozygous deletions often accompanied by deletions of the malic enzyme 2 (ME2) gene, leading to upregulation of malic enzyme 3 (ME3) to eliminate reactive oxygen species (ROS). We designed an aptamer-modified octahedral DNA nanostructure for targeted co-delivery of siRNA targeting ME3 (siME3) and doxorubicin (DOX).

Effect of Structure on Osteogenesis of Bone Scaffold: Simulation Analysis Based on Mechanobiology and Animal Experiment Verification.

Porous scaffolds, whose mechanical and biological properties are greatly affected by structure, are new treatments for bone defects. Since bone repair is related to biomechanics, analyzing the osteogenesis in scaffolds based on mechanical stimulation may become a more effective method than traditional biological experiments. A tissue regeneration algorithm based on mechanical regulation theory was implemented in this study to evaluate the osteogenesis of classical scaffolds (Gyroid, I-WP, and Diamond).

The updated prevalence and risk factors of dementia in old adults in China: A cross-sectional study.

Background: The continuously increasing aging population and life expectancy have led to an inconsistent and underestimated dementia prevalence in China. An updated epidemiologic study is urgently needed.
