Summary: In this study, facile intercalation and functionalization of β-cyclodextrin onto layered double hydroxides have resulted in the formation of accessible hydroxyl functional groups and anions that exhibit strong sorption and host-guest interaction with boron. The modified LDH was employed to fabricate a polyamide-based thin-film nanocomposite membrane with high salt rejection and water permeance for brackish water, achieving a high boron rejection rate as well. This pioneering study provides valuable insights into the design of brackish water reverse osmosis membranes using macrocyclic molecules and inorganic layered nanomaterials.

Summary: This study successfully grafted uniform and dense PAA membranes onto LDH nanosheets using an in-situ initiating and terminating radical graft polymerization method. By adjusting the ratio of initiated sites to terminated sites, the amount of redox initiator or monomer, the size, morphology and density of grafted PAA on LDH surfaces can be controlled. This enables the monodispersion of PAA@LDHs in PE and PVC matrices with greatly improved compatibility.

Summary: NiFe-based layer double hydroxides (NiFe-LDHs) have been widely recognized for their ability to enhance the oxygen evolution reaction (OER) in alkaline solutions. In this study, the introduction of different elements (M = Zn, Cu, Al, Cr, and Mn) into NiFe-x (x = 2-8) is investigated to further improve the OER performance. The introduction of element M, particularly Zn, significantly contributes to the OER performance, with NiFeZn-4 demonstrating low overpotential and high endurance. Long-term operation and accelerated testing further optimize the impedance and enhance the OER durability of NiFeZn-4.

Summary: This paper studied the pre-oxidation products, surface silicon content, hot-dip galvanized layer structure and corrosion resistance of nodular cast iron pre-oxidized by sodium bicarbonate through scanning electron microscopy, energy-dispersive spectrometry, and X-ray diffraction. It was found that the pre-oxidation product was mainly Fe2O3 at 100 degrees C, Fe2O3 and SiO2 at 200 degrees C, and mainly SiO2 at 300 degrees C. The thickness of the alloy layer in the zinc coating of nodular cast iron continuously decreased with increasing pre-oxidation temperature, and the thickness of the alloy layer at 300 degrees C was 43.9% lower than that without pre-oxidation.

Summary: This study investigated the in vitro protein digestibility, bioaccessibility, and intestinal absorption of minerals and trace elements in saltbush and samphire, two important Australian indigenous halophytes. The study found that samphire had higher in vitro digestibility of protein compared to saltbush, despite having a lower total protein content. Additionally, freeze-dried halophyte powder showed higher in vitro bioaccessibility of Mg, Fe, and Zn compared to the halophyte test food. The study also revealed differences in intestinal absorption rates of iron between samphire and saltbush.

Summary: Current treatment options for prostate cancer focus on targeting androgen receptor (AR) signaling, but inhibiting AR may promote the development of neuroendocrine prostate cancer (NEPC). Understanding the regulatory mechanisms of AR is crucial for the clinical management of NEPC. This study revealed the tumor-suppressive role of AR and identified its downregulation of CHRM4 expression. CHRM4 overexpression drives neuroendocrine differentiation in prostate cancer cells and is associated with immunosuppressive cytokine responses in the tumor microenvironment (TME). Targeting CHRM4 and evaluating IFNA17 secretion as a prognostic biomarker could be potential therapeutic strategies for NEPC.

Summary: The conventional treatment for prostate cancer is androgen-deprivation therapy (ADT), which inhibits tumor progression driven by androgen receptor (AR) signaling. ADT-induced recurrence of prostate cancer can develop into a neuroendocrine (NE) phenotype with metabolic disturbances and poor prognosis. However, the metabolic pathways that regulate NE differentiation (NED) in prostate cancer are still unclear.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
