As an emerging category of crystalline porous materials, covalent organic frameworks (COFs) are primarily synthesized solvothermal methods. However, achieving rapid synthesis of COFs through this approach poses a significant challenge. To address the issue of slow synthesis, we studied the crystallization process of aminal-linked COFs the condensation of a cost-effective aldehyde and secondary amine, and successfully expedited the synthesis of COFs within a one-hour duration. Furthermore, gram-scale aminal-linked COFs with abundant ultra-microporous channels demonstrated promising potential for CO/CH separation. This study enables the rapid synthesis of aminal-linked COFs from cheap raw materials, which lays a foundation for their practical applications.

A new methodology is presented for the rapid, specific, and sensitive detection of irinotecan (CPT-11), a chemotherapeutic agent utilized in the treatment of cancer, along with its metabolically active derivative, SN-38, via laser desorption/ionization mass spectrometry (LDI MS). The method includes the detection of camptothecin (CPT), which can be utilized as an internal standard for the quantitative assessment of both CPT-11 and SN-38 in mouse serum. The approach utilizes a plasmonic two-dimensional (2D) black phosphorus nanosheet (BPN)-gold nanomatrix (BP@Au) in LDI MS.

The intestinal epithelium is a rapidly self-renewing tissue; the rapid turnover prevents the invasion of pathogens and harmful components from the intestinal lumen, preventing inflammation and infectious diseases. Intestinal epithelial barrier function depends on the epithelial cell proliferation and junctions, as well as the state of the immune system in the lamina propria. Polyamines, particularly putrescine, spermidine, and spermine, are essential for many cell functions and play a crucial role in mammalian cellular homeostasis, such as that of cell growth, proliferation, differentiation, and maintenance, through multiple biological processes, including translation, transcription, and autophagy.

We hypothesized that a strategy employing tissue-specific endothelial cells (EC) might facilitate the identification of tissue- or organ-specific vascular functions of ubiquitous metabolites. An unbiased approach was employed to identify water-soluble small molecules with mitogenic activity on choroidal EC. We identified adenosine diphosphate (ADP) as a candidate, following biochemical purification from mouse EL4 lymphoma extracts.

Social norms, the informal rules that influence behavior, play essential roles in shaping people's behavior. Community-based norms-shifting interventions (NSIs) identify gender and other social norms linked to unhealthy behaviors and implement activities to promote collective change by encouraging communities to reflect on and question these norms. Though NSIs are gaining international traction in social and behavior change programming for health promotion, how change occurs needs to be clearly understood in African and other contexts.
