Strategies for specific multimodal imaging of cancer-associated fibroblasts and applications in theranostics of cancer.

Fibroblast activating protein (FAP) is up-regulated in cancer-associated fibroblasts (CAFs) of more than 90 % of tumor microenvironment and also highly expressed on the surface of multiple tumor cells like glioblastoma, which can be used as a specific target for tumor diagnosis and treatment. At present, small-molecule radiotracer targeting FAP with high specificity exhibit limited functionality, which hinders the integration of theranostics as well as multifunctionality. In this work, we have engineered a multifunctional nanoplatform utilizing organic melanin nanoparticles that specifically targets FAP, facilitating both multimodal imaging and synergistic therapeutic applications.

Thermo-sensitive polycaprolactone coacervates for preventing protein aggregation under thermal stress.

Inspired from heat shock proteins (HSPs), a thermo-sensitive coacervate-forming polycaprolactone (CPCL) was designed as a natural chaperone mimic to protect proteins from thermal stress. Unlike the coil-globule polymers of poly(-isopropyl acrylamide) (PNIPAM), the as-designed CPCL underwent a partial dehydration during heating, characterizing it as a coacervate-forming polymer. With its ability to transform between the coil and coacervate states in response to temperature, theCPCL spontaneously captured and released targeted proteins, thereby behaving like a natural chaperone of HSPs.

A study on sleep quality under the shadow of school bullying: The interwoven effects of depressed mood, low self-esteem, and negative parenting practices.

Objective: The aim of this study was to reveal the relationship between school bullying and sleep quality in adolescents. It proposes a theoretical model where depressed mood, low self-esteem, and negative parenting practices serve as mediating variables, providing new directions and measures for preventing and treating school bullying and sleep disorders.

Methods: In this study, a total of 4483 middle school students from Anhui Province in China were selected anonymously to participate in a questionnaire survey.

First report of causing winged leaf dieback disease on in Yunnan Province, China.

Rhus chinensis, a deciduous tree of the genus Rhus (family Anacardiaceae), is widely cultivated in China for its medicinal, edible, and ornamental value (Zhang et al., 2022). In April 2022, symptoms of winged leaf dieback disease were observed at Southwest Forestry University in Kunming, Yunnan Province, China (E102°45'42.

Regulation of reactive oxygen species and the role of mitochondrial apoptotic-related genes in rheumatoid arthritis.

Previous research suggests mitochondrial apoptosis alleviates rheumatoid arthritis (RA), but the role of mitochondrial apoptosis-related genes (MARGs) is unclear. Urgent exploration of RA-related mitochondrial apoptosis biomarkers is needed. Gene Expression Ontology (GEO)-derived RA datasets were used to identify differentially expressed genes (DEGs) compared to normal controls, intersected with MARGs to obtain differentially expressed mitochondrial apoptosis-related genes (DE-MARGs).
