“…In addition, the washing solution was extracted from the soil in batch soil washing experiments by means of a simple solid-liquid separation technique, comprising centrifugation at 3000 rpm for 20 min, followed by removal of the supernatant. Regarding soil characterization, elemental analysis was carried out by the acid digestion method (MW CEM MARS 5 System), according to the procedure described in Đolić et al 18 The metal concentration was analyzed by inductively coupled plasma mass spectrometry (ICP-MS; Agilent 7500ce ICP-MS system), equipped with an octopole collision/reaction cell. Chemical properties were determined by X-ray fluorescence (XRF) technique, using a Thermo Fisher Scientific Niton XL3 analyzer.…”

BACKGROUND Soil washing is a well‐known technology for the remediation of soils polluted by organic contaminants, including polycyclic aromatic hydrocarbons (PAHs). This study aimed to go further by integrating soil washing and permeable reactive barriers (PRBs) made of cork granules to remove PAHs from the soil. While PAHs may be transferred from the soil to the washing solution in the soil washing step, the cork PRB may provide the removal of PAHs from the washing solution, ultimately leading to the reuse of this solution. RESULTS The integrated approach was tested by means of packed bed column experiments in the absence and presence of cork PRBs. Two PAHs were under focus: fluorene (FLU) and phenanthrene (PHE). In soil with 0.5 mmol L−1 kgsoil−1 of FLU and PHE, the soil washing technique employing thermally treated cork granules and a solution of 70%/30% water/acetonitrile (v/v) flowing at 2.2 mL min−1 promoted the transfer of ~58% of PAHs from the soil to the washing solution, while the cork PRB retained ~98% of the PAHs from the washing solution. The acetonitrile content of the water/acetonitrile washing solutions contributed to the soil washing since it was responsible for PAH desorption and elution, however it was unfavorable for PAH sorption onto the cork as acetonitrile competed with PAHs for cork sorption sites. CONCLUSION Cork PRBs were able to retain PAHs from soil washing solutions and provide final solutions free of PAHs, demonstrating the viability of integrating solvent‐aided soil washing with cork PRBs. © 2022 Society of Chemical Industry (SCI).

“…Actually, hemp seed has a broad pharmacological effect in the gastrointestinal system [5], the cardiovascular system [6], the central nervous system, and the immune system [7]. Recently, hemp seed extracts were reported for their anti-aging effects and the potential to improve impaired learning and memory induced by chemical drugs in mice [8,9]. Meanwhile, recent studies showed that excluding oil and protein, hemp seed is rich in lignanamides [10,11], and that no matter hemp seed oil, protein or lignanamides all have anti-aging effect on old mice [12].…”

Hemp seed (Fructus cannabis) is rich in lignanamides, and initial biological screening tests showed their potential anti-inflammatory and anti-oxidative capacity. This study investigated the possible effects and underlying mechanism of cannabisin F, a hempseed lignanamide, against inflammatory response and oxidative stress in lipopolysaccharide (LPS)-stimulated BV2 microglia cells. Cannabisin F suppressed the production and the mRNA levels of pro-inflammatory mediators such as interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) in a concentration-dependent manner in LPS-stimulated BV2 microglia cell. Furthermore, cannabisin F enhanced SIRT1 expression and blocked LPS-induced NF-κB (Nuclear factor kappa B) signaling pathway activation by inhibiting phosphorylation of IκBα (Inhibit proteins of nuclear factor kappaB) and NF-κB p65. And the SIRT1 inhibitor EX527 significantly inhibited the effect of cannabisin F on pro-inflammatory cytokines production, suggesting that the anti-inflammatory effects of cannabisin F are SIRT1-dependent. In addition, cannabisin F reduced the production of cellular reactive oxygen species (ROS) and promoted the expression of Nrf2 (Nuclear factor erythroid-2 related factor 2) and HO-1 (Heme Oxygenase-1), suggesting that the anti-oxidative effects of cannabisin F are related to Nrf2 signaling pathway. Collectively, these results suggest that the neuro-protection effect of cannabisin F against LPS-induced inflammatory response and oxidative stress in BV2 microglia cells involves the SIRT1/NF-κB and Nrf2 pathway.
