Article Synopsis
  • - The study investigates how nitric oxide (NO) enhances polysaccharide production in Nostoc flagelliforme through a process called S-nitrosylation (SNO), which modifies certain enzymes involved in this biosynthesis.
  • - It was found that certain key enzymes (G6PDH, ICDH, and UGDH) have their activity correlated with NO levels, and specific enzymes (UGDH and G6PDH) are particularly affected by SNO, as shown through various laboratory techniques.
  • - The research identifies specific sites on the enzymes that are modified by NO and proposes that this mechanism could lead to improved industrial production of polysaccharides from Nostoc flagelliforme.

Swine wastewater (SW) contains high levels of traditional pollutants, antibiotics, and antibiotic resistance genes (ARGs), necessitating effective elimination. Two parallel aerobic granular sludge (AGS) reactors, R and R, were constructed and optimized for treating SW from two pig farms, identified as SW and SW. R showed higher antibiotic removal efficiency, particularly in the removal of sulfonamides, while fluoroquinolones tended to adsorb onto the sludge.

Decidualization is a process in which endometrial stromal fibroblasts differentiate into specialized secretory decidual cells and essential for the successful establishment of pregnancy. The underlying mechanism during decidualization still remains poorly defined. Because decidualization and fibroblast activation share similar characteristics, this study was to examine whether fibroblast activation is involved in decidualization.

Sanjin tablets (SJT) are a well-known Chinese patent drug that have been used to treat urinary tract infections (UTIs) for the last 40 years. The drug consists of five herbs, but only 32 compounds have been identified, which hinders the clarification of its effective substances and mechanism. The chemical constituents of SJT and their effective substances and functional mechanism involved in the treatment of UTIs were investigated by using high performance liquid chromatography-electrospray ionization-ion trap-time of flight-mass spectrometry (HPLC-ESI-IT-TOF-MS), network pharmacology, and molecular docking.

Article Synopsis
  • The increasing problem of global antimicrobial resistance highlights the urgent need for new therapeutic strategies, as few new antibiotics have been created in recent years.
  • Researchers developed a screening platform that identified three flavonoids—7,8-dihydroxyflavone, myricetin, and luteolin—that enhance the effectiveness of the antibiotic colistin.
  • These flavonoids disrupt bacterial iron balance by converting ferric to ferrous iron, which improves colistin's binding and effectiveness, showing potential for future antibacterial therapies targeting iron signaling.

The establishment of pregnancy depends on interactions between the epithelial and stromal cells of the endometrium that drive the decidual reaction that remodels the stroma and enables embryo implantation. Decidualization in mice also depends on ovarian hormones and the presence of a blastocyst. Hedgehog signaling is transduced by primary cilia in many tissues and is involved in epithelial-stromal cross-talk during decidualization.
