The discharge of dye wastewater and waste-oil has brought serious harm to the ecological environment and human health. Unfortunately, bifunctional adsorbents towards aqueous dyes in water- and oil-soluble dyes in organic media are still rare to date. In this research, magnetic ferric alginate carbon aerogel (FeACA) was prepared from sodium alginate by wet spinning, Fe 3+ -ion cross-linking, and pyrolysis in N 2 atmosphere. FeACA obtained a specific surface area of 215.3 m 2 g −1 with a mean pore size of 3.1 nm and exhibited near superparamagnetic character. The adsorption capacities of FeACA for methylene blue, Congo red, and oil red O were 123.7, 141.1, and 65.7 mg g −1 , respectively. FeACA revealed a good broad-spectrum adsorption performance for other eleven various types of dyes. This study demonstrates a fast adsorption strategy by combining the magnetic separation and ethanol desorption. Utilizing the strategy, the adsorption time of MB was reduced from 12 h to 205 min with half dosage of adsorbent. This research provides new insights for achieving multifunctional dye adsorption.

We present a facile and an inexpensive approach to prepare robust fluorine-free self-cleaning cotton textiles by surface modification with anatase TiO 2 sol and polydimethylsiloxane (PDMS) using a simple dip-coating method. The synergetic effect of the anatase TiO 2 particles and PDMS was critical and essential for obtaining a superhydrophobic coating with photocatalytic activity and UV durability. The coated cotton textiles not merely exhibited desirable superhydrophobic property with a water contact angle (WCA) of 153.8°, but also performed the considerable photocatalytic activity by the decomposition of oil red O under UV exposure. Importantly, the as-obtained self-cleaning cotton textiles were stable under various harsh conditions such as acidic, alkaline, corrosive organic solutions, and laundering. Moreover, the coated cotton textiles could also maintain its superhydrophobicity when exposed to long-term UV irradiation , displaying its excellent UV resistance. Therefore, this simple preparation approach can be regarded as a promising way to construct self-cleaning surfaces for scale up production.

Buyang Huanwu Decoction (BHD) has lipid-lowering and antioxidant effects. In this study, HPLC was used to establish the fingerprint of extracts from different polar parts of BHD. Through the L02 cell lipid deposition model induced by oleic acid, extracts from different polar parts of BHD were administered for treatment. Oil red O staining, TG detection, and MDA detection were used to determine lipid deposition and antioxidant activity. The component-effect relationship is established by using grey relational analysis and PLSR analysis. The results showed that the extracts from different polar parts of BHD could reduce the levels of TG and MDA. The grey relational analysis showed that the peaks that contributed greatly to the reduction of TG and MDA were peaks 3, 16, 14, 10, 1, 15, 2, and 11, respectively. Peaks 1, 4, 9, 10, 14, 16, and 17 could reduce TG and MDA through PLSR analysis. According to the results of grey relational analysis and PLSR analysis, peaks 1, 10, 14, and 16 may have good lipid-lowering and antioxidant effects. This study provides a certain preliminary basis for follow-up research on lipid-lowering drugs.

Baicalin is a flavonoid compound abundant in multiple edible and medicinal plants such as Scutellaria baicalensis Georgi . In this study, we provide evidence to support the fact that baicalin ameliorates alcohol-induced hepatic steatosis via regulating SREBP1c elicited PNPLA3 competitive binding to ATGL . Results showed that baicalin significantly attenuated the development of metabolic disorders and hepatic steatosis in alcohol-induced rats after four weeks of treatment. It was evident that baicalin treatment significantly normalized the serous contents of hepatic triglyceride (TG), alanine aminotransferase (ALT), and aspartate aminotransferase (AST), and attenuated the increase of hepatic vacuolization and Oil Red O staining area caused by alcohol. Meanwhile, baicalin relieves alcohol-induced hepatic fibrosis by masson staining and RT-qPCR analysis. Mechanistically, alcohol aggravated the nuclear expression of SREBP1c, which contributed to the high expression of PNPLA3 and FASN , thereby enhancing the binding of PNPLA3 to ABHD5 , and indirectly impairing the binding ability between ATGL and ABHD5, ultimately causing a decline in the hydrolysis capacity in liver lipid droplets . As expected, these alcohol-induced pathobolism were reversed by baicalin treatment both in vivo and in vitro . In conclusion, this study has demonstrated that baicalin can protect against alcohol-induced hepatic lipid accumulation by activating hepatic lipolysis via suppressing SREBP1c elicited PNPLA3 competitive binding to ATGL. Baicalin is a promising natural product for preventing alcohol-induced hepatic steatosis.

The present study sought to investigate the protective effect of Lycopene (LYC) on Bisphenol A (BPA)-induced lipid accumulation and elucidate the potential molecular mechanism. In vitro, the PK15 cells with or without LYC were exposed to BPA for 6 h to detect the lipid accumulation using Nile red’s and Oil Red O’ staining. Meanwhile, redox status, mitochondrial function, gene expression and protein levels relating to lipid accumulation were evaluated by cellular biochemical assays, immunofluorescence staining, quantitative real-time PCR (qRT-PCR) and Western blot, respectively. In addition, ROS scavenger N-acetylcysteine (NAC), SIRT1 inhibitor EX527, SIRT1 siRNA and PGC-1α siRNA were used to verify the target signaling pathways responsible for the protective effect of LYC against BPA-indcued lipid accumulation. In vivo, the twenty four male Wistar rats were randomly divided into three groups, received either BPA (50 mg/kg/day BW) or LYC (10 mg/kg/day BW) orally for 60 days. The kidney tissues were evaluated by HE’s and Oil Red O’s staining, lipid-associated genes and proteins expression were detected through qRT-PCR and Western blot. The results showed that BPA-exposed PK15 cells and rats had increased lipid droplets with elevated transcription of lipogenic factors SREBP1 and PPARγ, and down-regulated PPARα expression, and which is accompanied by redox imbalance and abnormal mitochondrial function. Conversely, LYC prevented BPA-induced lipid metabolism disorder and lipid accumulation through impeding ROS overproduction. Moreover, PK15 cells and rats exposed to BPA showed decrease in SIRT1 and PGC-1α levels, whereas LYC blocked the decrease of SIRT1 and PGC-1α protein levels. Furthermore, inhibition or silence of SIRT1 and PGC-1α abrogated the improvements of LYC on ROS generation, mitochondrial mass impairement and lipid accumulation in BPA-treated PK15 cells. Collectively, these findings indicate that SIRT1/PGC-1α signaling pathway is involved in the protective effect of LYC on BPA-induced lipid accumulation. These results also provide a potential promising therapeutic of LYC against BPA-induced lipid accumulation in kidney cells and organs.

The development of economic and functional papers relies on the introduction of functional filler particles but faces several challenges, especially the low filler retention and inferior mechanical properties. This study introduces plant-based cellulose nanofibrils (CNFs) as dual-function retention and strengthening agents, offering a sustainable alternative to petroleum-based polymer additives. Precipitated calcium carbonate (PCC), a widely used filler, is selected as the model system. The effects of CNF dosage, aspect ratio, and surface carboxyl content on the filler flocculation process were systematically investigated, with additional enhancement achieved through cationic ion crosslinking to improve filler bridging. Remarkably, a superior filler retention rate (>90 %) and filler-tensile factor (2.0) were achieved for the final papers at very low CNF dosage (1 %), surpassing most literature data. Detailed analyses of filler morphology and distribution elucidated the structure-property relationships underlying this performance. Furthermore, the versatility of the approach was demonstrated with other functional fillers, imparting properties such as flame retardancy, oil/water separation, high brightness, and soluble organic pollutant absorption. Overall, this study reveals the critical feature of CNFs in simultaneously improving filler retention and mechanical properties, demonstrating their high potential for their applications in the papermaking industry.

Polylactic acid (PLA) membranes offer advantages such as biodegradability, non-toxicity, and biocompatibility for oil–water separation. However, it remains challenging to fabricate PLA membranes with sufficient mechanical strength and hydrophobicity for practical applications. In this study, a superhydrophobic fibrous membrane based on PLA and Polybutylene terephthalate adipate (PBAT) is prepared via electrospinning, followed by a high-humidity treatment. The effects of PBAT content and high humidity treatment on the morphology, hydrophobicity, and mechanical properties of PBAT/PLA composite fiber membranes are investigated. The results show that the introduction of PBAT effectively enhances the fiber diameter, crystallization, hydrophobicity, and mechanical properties of PBAT/PLA fibers. Moreover, the high humidity treatment further improves the mechanical and hydrophobic properties of the membranes. When 0.2 g of PBAT is added and the high humidity treatment lasts for 24 h, the resulting PBAT/PLA fibrous membrane exhibits an outstanding water contact angle (WCA) of 158.23°, tensile strength of 3.802 MPa, excellent oil–water separation flux (6500 L/(m 2 ·h)), and efficiency of 99.80%, demonstrating great potential for oil–water separation applications.

The preparation of stable and efficient cellulose-based oil/water separation membranes is of great significance in solving the problem of industrial oily wastewater. Herein, rod-like hydroxyapatite (HAP) modified microfibrillated celluloses (MFCs) are used to form the fibrous framework to produce a microporous PDMS-MFC-HAP membrane. The membrane shows good superhydrophobicity with a water contact angle of 151.6°. It exhibits the oil-water separation performance for various water-in-oil emulsions. The separation flux of the membrane is up to 3665.3 L·m −2 ·h −1 ·bar −1 under 0.5 bar pressure with a separation efficiency of over 99.6 %. The PDMS-MFC-HAP membrane could maintain a high separation efficiency of 98.6 % after 20 cycles. This study provides a simple and effective method to fabricate cellulose-based superhydrophobic membranes, which have a greater potential to achieve oil-water separation for oily wastewater treatment with high efficiency.

Ethosomes are ethanol-based liposomes which may self-assemble in alcoholic beverages and exhibit dual effects: nanoscale ethanol has liver-targeting property with potential hepatotoxicity on the one side, while ethosomes can encapsulate active constituents that provide hepatoprotective benefits on the other side. This study investigated the dual role of ethosomes, focusing on their existence, characterization, potential toxicity, and toxicological mechanisms. Our results confirmed the existence of ethosomes in alcoholic beverages using particle size analysis, ultracentrifugation, liquid chromatography-mass spectrometry, and transmission electron microscopy. Both in vitro and in vivo experiments revealed that ethosomes can cause significant liver injury in a short period, associated with abnormal secretion of transforming growth factor-β ( TGF-β ) by parenchymal cells and subsequent apoptosis of Kupffer cells. Notably, the toxicity of ethosomes was significantly reduced when encapsulated natural active compounds like oleanolic acid. In conclusion, ethosomes could form self-assembly in the production progress of the integrated alcoholic beverages. The present study underscored the dual impact of ethosomes on alcoholic liver disease and offered new insights into the safety risk assessment of alcoholic beverages.

The Janus membranes with asymmetric wettability can gate oil or water transport spontaneously and directionally to facilitate the liquids transport for oil/water emulsions separation without extra energy consumption, which have attracted wide attention. However, this single-functioned either oil or water removal Janus membranes can only separate one type of emulsions and cannot meet the requirements in complex environments. Herein, a bi-functional Janus mesh membrane with selective directional oil- and water-transport integration induced by direction-directed dual asymmetric wettability is demonstrated for energetic-efficient on-demand separation of oil-in-water and water-in-oil emulsion. An ingenious double single-side asymmetric modification strategy is proposed to make a homogenous mesh membrane with special Janus interface, where one surface features oleophobicity and hydrophilicity while the other shows superhydrophobicity and oleophilicity. This direction-directed wettability imbalance gives rise to the selective directional both water and oil transport property, namely , one surface directionally transports oil and block water. In contrast, the other surface suspends the oil and directionally transports water across the membrane. According to this property, this multifunctional Janus mesh membrane achieves high-performance on-demand oil-in-water and water-in-oil emulsions separation without extra energy consumption.

Oil pollution poses severe threats to both ecosystems and human health. This study utilized electrospinning and carbonization processes to fabricate a SiO2-TiO2-C nanofiber membrane (STCNFM) exhibiting photocatalytic self-cleaning properties designed explicitly for oil-water separation. These membranes possess nanoscale rough structures, endowing them with superoleophilicity (0°) and hydrophobicity (138°). Addressing the limitations associated with traditional ceramic membranes, particularly in terms of stability and reproducibility, cyclic experiments confirm the significant stability and reproducibility of this composite membrane, ensuring reliable long-term applications for continuous oil-water separation. Leveraging the synergistic effect of TiO2 and the carbon fiber substrate, STCNFMs-5 demonstrate exceptional separation performance and notable self-cleaning capabilities. Following a 2-h exposure to ultraviolet light, the membrane's flux is restored to its original level. STCNFMs offer a promising solution for efficiently separating oil-water mixtures and emulsions, holding potential importance in water treatment and resource recovery endeavors.

Nonalcoholic fatty liver disease (NAFLD) is a worldwide public health issue, but a widely accepted therapy is still lacking until now. Anthocyanins are natural flavonoid compounds that possess various bioactivities, but their applications are limited due to their low bioavailability and stability. Acylated anthocyanins are reported to show higher stability, whereas their effects on NAFLD are still unclear. Herein, pelargonidin-3-O-(6′′-acetyl)-glucoside (Ace Pg3G) was found to dose-dependently reduce intracellular lipid droplets and triglycerides, and improve cellular oxidative stress that accompanied lipid deposition. Besides, Ace Pg3G was proved to activate AMPK phosphorylation, thus stimulating AMPK-mediated lysosome-autophagy pathway to eliminate overloaded lipid. Further study unveiled that Ace Pg3G regulated genes related to lipid metabolism downstream of AMPK to inhibit lipid synthesis and accelerate lipid oxidation. Overall, this study provided the first evidence, to our best knowledge, that Ace Pg3G ameliorated free fatty acid-induced lipid deposition in hepatocytes through regulating AMPK-mediated autophagy pathways and redox state.
