Fenton reactions, commonly employed in environmental remediation, decompose H₂O₂ using Fe⁺ to generate free radicals. However, the efficiency is often limited by the slow conversion of Fe³⁺ to Fe⁺. In this study, we synthesize zero-valent iron nanoparticles (nZVI) via a green, plant extract-mediated reduction method, resulting in nZVI coated with a reductive polyphenolic layer that enhances Fe³⁺/Fe⁺ cycling.

Programming precise and specific microbial intraspecies or interspecies interaction would be powerful for microbial metabolic regulation, signal pathway mechanism understanding, and therapeutic application. However, it is still of great challenge to develop a simple and universal method to artificially encode the microbial interactions without interfering with the intrinsic cell metabolism. Here, we proposed an extensible and flexible framework nucleic acid strategy for encoding the specific and precise microbial interactions upon self-assembly.

In clinical practice, some cases of chronic spontaneous urticaria (CSU) remain difficult to treat, with up to 40% of patients showing no response to even high (4-fold) daily doses of antihistamines. Approximately 30% of CSU patients fail to achieve complete control and relief through treatment with omalizumab and may require alternative therapies. Abrocitinib is a small-molecule oral JAK1 inhibitor that suppresses intracellular signaling of multiple key cytokines involved in inflammation cascades, and has shown beneficial effects in patients with mast cell activation disorders.

Article Synopsis
  • Liver fibrosis is a process involving liver tissue damage and repair, primarily driven by the activation of hepatic stellate cells, making understanding their mechanisms crucial for treatment.
  • In experimental studies, overexpressing ASIC1a in liver cells and using Sorafenib revealed that the induction of ferroptosis can effectively inhibit liver fibrosis progression.
  • The findings show that overexpression of ASIC1a reduces ferroptosis and alters the activity of the Hippo/YAP signaling pathway, indicating a complex relationship between calcium influx and liver cell activation.

Nitrobenzothiazinones (BTZs) represent a novel type of antitubercular agents targeting DprE1. Two clinical candidates BTZ043 and PBTZ169, as well as many other BTZs showed potent anti-TB activity, but they are all highly lipophilic and their poor aqueous solubility is still a serious issue need to be addressed. Here, we designed and synthesized a series of new BTZ derivatives, wherein a hydrophilic COOH or NH group is directly attached to the oxime moiety of TZY-5-84 discovered in our lab, through various linkers.

Hypothesis: Simple single-chain amphiphiles (sodium monododecyl phosphate, SDP) and organic small molecules (isopentenol, IPN), both of primitive relevance, are proved to have been the building blocks of protocells on the early Earth. How do SDP-based membrane and coexisting IPN come together in specific ways to produce more complex chemical entities? What kind of cell-like behavior can be endowed with this protocell model? These are important questions in the pre-life chemical origin scenario that have not been answered to date.

Experiments: The phase behavior and formation mechanism of the aggregates for SDP/IPN/HO ternary system were characterized and studied by different electron microscopy, fluorescent probe technology, DLS, IR, ESI-MS, SAXS, etc.
