Asthma, a common chronic pulmonary disorder characterized by airway remodeling, hyperresponsiveness and obstruction, can be aggravated by repeated exposure to particulate matter (PM). The potential effect and mechanisms of Radix essential oil (AEO) against asthma were explored based on network pharmacology. AEO was pre-treated using a nebulizer for 3 weeks and the mice were sensitized to ovalbumin (OVA) and PM with the co-treatment of AEO for 4 weeks. In addition, A549 lung epithelial cells were sensitized with PM to investigate the underlying mechanisms of AEO regarding the lung-fibrosis-related mediators. The target genes of methyl eugenol, a main compound of AEO, were highly matched by 48% with the gene set of asthma. AEO markedly inhibited the increase in epithelial thickness through the accumulation of goblet cells in the airways. Collagen deposition in the lung tissues of OVA+PM-challenged asthmatic mice was significantly decreased by AEO. AEO also inhibited the influx of inflammatory cells in the bronchoalveolar lavage fluid, as well as the increases in serum IgE and IgG and cytokines in the lung tissues. Furthermore, AEO regulated the expressions of fibrotic mediators, especially POSTN and TGF-β. In conclusion, we expect that AEO can be one of the effective alternative therapeutics to relieve asthma.

Acne is a multifactorial dermatological condition driven by Propionibacterium acnes (P. acnes) infection, inflammation, and sebum dysregulation. While essential oils, such as Angelica sinensis (Danggui) essential oil (AEO), exhibit antimicrobial and anti-inflammatory properties, their clinical application is hindered by poor solubility, stability, and skin penetration.

Surfactants play a crucial role in enhancing pesticide wetting; however, their effectiveness is influenced by pathogen-induced interfacial heterogeneity, such as the presence of hydrophobic and hydrophilic microdomains, particularly in the context of apple rust. Conventional homogeneous surfactant strategies lack the adaptability required to effectively address these dynamically changing interfaces. This study synthesizes insights from interfacial dynamics and plant pathology to elucidate the adaptive interactions of AEO-series nonionic surfactants with rust-infected leaves.

This study was conducted at an oil-sands operation in the North Athabasca Oil Sands Region, Alberta, Canada to identify suitable isotopic tracers for differentiating between processed (anthropogenic) and non-processed bitumen residues in water. A combination of isotopes of water, solutes, and acid-extractable organics (AEO) were measured in tailings ponds containing oil-sands process water (OSPW), groundwater from the basal McMurray Formation, and a variety of on-lease groundwater monitoring wells and mitigation structures, the latter designed to intercept potentially contaminated runoff. This study provides supporting evidence that tailings ponds are well-contained and are not hydraulically connected with monitoring wells in local Quaternary aquifers or underlying formations at the investigated site.

In this study, we employed a combination of theoretical and experimental analyses to explore the effects of the physico-chemical properties of lignite samples and surfactants on lignite dust's wettability, thereby improving dust control in coal mines. First, we measured and analysed the coal samples' industrial composition, elemental composition and chemical structure. It was found that the selected lignite dust has high ash and low moisture content and contains many hydrophobic functional groups, resulting in poor wettability by water.

Context: In coal mine spray dust suppression, conventional studies on individual surfactants or surfactant mixtures often fail to achieve optimal coal wettability enhancement. This study innovatively introduces SiO₂ nanoparticles and demonstrates through simulations that the nanoparticle-surfactant composite system substantially enhances coal wettability. Electrostatic potential analysis indicates that the modified nanoparticle molecules formed by surfactant-grafted nanoparticles are more likely to form stable structures with coal molecules, enabling the nanoparticles to be better fixed on the coal molecules and establish a stable adsorption configuration.
