The unique design of low molecular weight hydrogels (LMWH) without carriers has sparked great interest in biomedical applications, yet the construction of binary LMWH remains elusive due to the lack of a theoretical framework linking structure and assembly. Hence, we proposed an innovative theoretical framework, in which a subtle -OH change in parent structures triggers the interconversion of nanoparticles and nanofibers. This framework hinges on a pair of hydrophobic planar small molecules with only one -OH difference, self-assembling into binary LMWH at 1:1 ratio.

Idiopathic pulmonary fibrosis (IPF) is a fatal, irreversible lung disorder with limited treatment options. Pathogenic drivers include fibroblast-to-myofibroblast transition, excessive collagen deposition, and inflammatory infiltration. Elevated circulating insulin-like growth factor-1 (IGF-1) levels and dysregulated activation of the IGF-1 receptor (IGF-1R) are implicated in multiple pathological conditions such as cancer, chronic inflammation, and fibrotic diseases.

Pesticide contamination in food poses a significant threat to both human well-being and ecological security. In this study, a two-dimensional Zn cluster coordination polymer material, {[Zn(CAP)(OH)(HO)]·NMP·HO} (CP 1), was synthesized and employed as a fluorescence sensor for the detection of organophosphorus pesticides, particularly methyl parathion (PAM) and parathion (PAR). Crystal structure analysis and Hirshfeld surface analysis revealed the abundance of intermolecular hydrogen bonds within CP 1, which facilitated recognition sites for selective interaction with PAM or PAR.

Small cell carcinoma of the esophagus (SCCE) is an aggressive and rare neuroendocrine malignancy with poor prognosis. Here, we firstly performed single-cell transcriptional profiling derived from 10 SCCE patients, with normal esophageal mucosa, adjacent non-malignant tissue and tumors from esophageal squamous cell carcinoma (ESCC) as reference. We observed enrichment of activated regulatory T cells and an angiogenesis-induced niche existed in SCCE compared with ESCC, revealing an immune suppressive and vessel-induced tumor microenvironment (TME) in SCCE.

Total sea ice extent (SIE) across the Southern Ocean increased from 1979-2014, but declined rapidly after 2016. Significant sea ice decline has emerged since the peak of SIE in 2014, coincident with Pacific sub-decadal sea surface temperature (SST) trends resembling a strong La Niña-like cold condition and the negative phase of the interdecadal Pacific oscillation (IPO). Previous studies suggest that the warm subsurface Southern Ocean was an important driver of the low sea ice in spring 2016 and the sustained low sea ice state since.

Article Synopsis
  • Studies show that the arrangement of chiral molecules greatly impacts how they self-assemble, but the effects of epimerization (changes in a single chiral center) had not been previously examined.
  • This research focused on two epimers of glycyrrhetinic acid—18 α and 18 β—derived from Glycyrrhiza uralensis, which exhibit different medicinal properties.
  • The findings revealed that 18 β-GA can create a nanoparticle structure through a 'head-to-tail' arrangement, while 18 α-GA struggles to assemble due to steric hindrance caused by a 'head-to-head' connection, highlighting how small structural changes can affect molecular behavior and potential applications in medicine.
