Toward robust lithium-sulfur batteries via advancing Li2S deposition.

Lithium-sulfur batteries (LSBs) with two typical platforms during discharge are prone to the formation of soluble lithium polysulfides (LiPS), leading to a decrease in the cycling life of the battery. Under practical working conditions, the transformation of S8 into Li2S is cross-executed rather than a stepwise reaction, where the liquid LiPS to solid Li2S conversion can occur at a high state of charge (SOC) to maintain the current requirement. Therefore, advancing Li2S deposition can effectively reduce the accumulation of LiPSs and ultimately improve the reaction kinetics. Herein, a "butterfly material" GeS2-MoS2/rGO is used as a sulfur host. Rich catalytic heterointerfaces can be obtained via the abundant S-S bonds formed between GeS2 and MoS2. MoS2 (left wing) can enhance LiPS adsorption, while the lattice-matching nature of Fdd2 GeS2 (right wing) and Fm3̄m Li2S can induce multiple nucleation and regulate the 3D growth of Li2S. Li2S deposition can be advanced to occur at 80% SOC, thereby effectively inhibiting the accumulation of soluble LiPSs. Attributed to the synergistic effect of catalytic and lattice-matching properties, robust coin and pouch LSBs can be achieved.

Wavelength dependency and photosensitizer effects in UV-LED photodegradation of iohexol.

Iodinated X-ray contrast media (ICM) are ubiquitously present in water sources and challenging to eliminate using conventional processes, posing a significant risk to aquatic ecosystems. Ultraviolet light-emitting diodes (UV-LED) emerge as a promising technology for transforming micropollutants in water, boasting advantages such as diverse wavelengths, elimination of chemical additives, and no induction of microorganisms' resistance to disinfectants. The research reveals that iohexol (IOX) degradation escalates as UV wavelength decreases, attributed to enhanced photon utilization efficiency. Pseudo-first-order rate constants (kobs) were determined as 3.70, 2.60, 1.31 and 0.65 cm2 J-1 at UV-LED wavelengths of 255, 265, 275 and 285 nm, respectively. The optical properties of dissolved organic matter (DOM) and anions undeniably influence the UV-LED photolysis process through photon competition and the generation of reactive substances. The influence of Cl- on IOX degradation was insignificant at UV-LED 255, but it promoted IOX degradation at 265, 275 and 285 nm. IOX degradation was accelerated by ClO2-, NO3-and HA due to the formation of various reactive species. In the presence of NO3-, the kobs of IOX followed the order: 265 > 255 > 275 > 285 nm. Photosensitizers altered the spectral dependence of IOX, and the intermediate photoactivity products were detected using electron spin resonance. The transformation pathways of IOX were determined through density functional theory calculations and experiments. Disinfection by-products (DBPs) yields of IOX during UV-LED irradiation decreased as the wavelength increased: 255 > 265 > 275 > 285 nm. The cytotoxicity index value decreased as the UV-LED wavelength increased from 255 to 285 nm. These findings are crucial for selecting the most efficient wavelength for UV-LED degradation of ICM and will benefit future water purification design.

MitoQ protects against carbon tetrachloride-induced hepatocyte ferroptosis and acute liver injury by suppressing mtROS-mediated ACSL4 upregulation.

Ferroptosis has been shown to be involved in carbon tetrachloride (CCl4)-induced acute liver injury (ALI). The mitochondrion-targeted antioxidant MitoQ can eliminate the production of mitochondrial reactive oxygen species (mtROS). This study investigated the role of MitoQ in CCl4-induced hepatocytic ferroptosis and ALI. MDA and 4HNE were elevated in CCl4-induced mice. In vitro, CCl4 exposure elevated the levels of oxidized lipids in HepG2 cells. Alterations in the mitochondrial ultrastructure of hepatocytes were observed in the livers of CCl4-evoked mice. Ferrostatin-1 (Fer-1) attenuated CCl4-induced hepatic lipid peroxidation, mitochondrial ultrastructure alterations and ALI. Mechanistically, acyl-CoA synthetase long-chain family member 4 (ACSL4) was upregulated in CCl4-exposed human hepatocytes and mouse livers. The ACSL4 inhibitor rosiglitazone alleviated CCl4-induced hepatic lipid peroxidation and ALI. ACSL4 knockdown inhibited oxidized lipids in CCl4-exposed human hepatocytes. Moreover, CCl4 exposure decreased the mitochondrial membrane potential and OXPHOS subunit levels and increased the mtROS level in HepG2 cells. Correspondingly, MitoQ pretreatment inhibited the upregulation of ACSL4 in CCl4-evoked mouse livers and HepG2 cells. MitoQ attenuated lipid peroxidation in vivo and in vitro after CCl4 exposure. Finally, MitoQ pretreatment alleviated CCl4-induced hepatocytic ferroptosis and ALI. These findings suggest that MitoQ protects against hepatocyte ferroptosis in CCl4-induced ALI via the mtROS-ACSL4 pathway.

Meta-Analysis of the Efficacy and Safety Evaluation of Vandetanib in the Treatment of Medullary Thyroid Cancer.

The aim of the work was to systematically evaluate the efficacy and safety of Vandetanib in the treatment of advanced medullary thyroid carcinoma (MTC). MeSH entries to search for randomized controlled trials and clinical research literature on the application of Vandetanib in the treatment of medullary thyroid cancer from PubMed, Chinese national knowledge infrastructure (CNKI), and Web of Science databases since their establishment until March 2023 were used. In terms of efficacy, the analysis results showed that Vandetanib had a significantly higher objective response rate compared to the control group using placebo (OR=2.13, 95% CI: 1.38, 3.29). In terms of side effects, Vandetanib significantly increases the incidence of hypertension, rash, and diarrhea, and has statistical significance (p+<+0.05). Vandetanib has a better therapeutic effect on MTC, but it also increases the incidence of hypertension, rash, and diarrhea. Attention should be paid to the relief of side effects when using it.

1,25(OH)2D3 alleviates oxidative stress and inflammation through up-regulating HMGCS2 in DSS-induced colitis.

BACKGROUND: Previous study found that supplements with active vitamin D3 alleviated experimental colitis. The objective of this study was to investigate the possible role of 3-hydroxy-3-methylglutaryl-CoA synthase 2 (HMGCS2), a ketone synthase, on vitamin D3 protecting against experimental colitis. METHODS: HMGCS2 and vitamin D receptor (VDR) were measured in UC patients. The effects of vitamin D deficiency (VDD) and exogenous 1,25(OH)2D3 supplementation on experimental colitis were investigated in dextran sulfate sodium (DSS)-treated mice. DSS-induced oxidative stress and inflammation were analyzed in HT-29 cells. HMGCS2 was detected in 1,25(OH)2D3-pretreated HT-29 cells and mouse intestines. HMGCS2 was silenced to investigate the role of HMGCS2 in 1,25(OH)2D3 protecting against experimental colitis. RESULTS: Intestinal HMGCS2 downregulation was positively correlated with VDR reduction in UC patients. The in vivo experiments showed that VDD exacerbated DSS-induced colitis. By contrast, 1,25(OH)2D3 supplementation ameliorated DSS-induced colon damage, oxidative stress and inflammation. HMGCS2 was up-regulated after 1,25(OH)2D3 supplementation both in vivo and in vitro. Transfection with HMGCS2-siRNA inhibited antioxidant and anti-inflammatory effects of 1,25(OH)2D3 in DSS-treated HT-29 cells. CONCLUSION: 1,25(OH)2D3 supplementation up-regulates HMGCS2, which is responsible for 1,25(OH)2D3-mediated protection against oxidative stress and inflammation in DSS-induced colitis. These findings provide a potential therapeutic strategy for alleviating colitis-associated oxidative stress and inflammation.

Combining proteomic markers to construct a logistic regression model for polycystic ovary syndrome.

Introduction: Proteomics technology has been used in various fields in recent years for the Q6 exploration of novel markers and the study of disease pathogenesis, and has become one of the most important tools for researchers to explore unknown areas. However, there are fewer studies related to the construction of clinical models using proteomics markers. Methods: In our previous study we used DIA proteomics to screen for proteins that were significant in 31 PCOS patients compared to women of normal reproductive age. In this study, we used logistic regression among these protein markers to screen out variables with diagnostic value and constructed logistic regression models. Results: We constructed a logistic model using these protein markers, where HIST1H4A (OR=1.037) was an independent risk factor for polycystic ovary syndrome and TREML1 (OR=0.976) were protective factors for the disease. The logistic regression model equation is: Logit (PCOS) =0.036*[HIST1H4A]-0.024*[TREML1]-16.368. The ROC curve analyzing the diagnostic value of the model has an AUC value of 0.977 and a Youden index of0.903, which gives a cutoff value of 0.518 at this point. The model has a sensitivity of 93.5% and a specificity of 96.8%. Calibration curves show fair consistency of the model. Discussion: Our study is the first to use proteomic results with clinical biochemical data to construct a logistic regression model, and the model is consistent. However, our study still needs a more complete sample to confirm our findings.

Controllable Synthesis of Hemoglobin-Metal Phosphate Organic-Inorganic Hybrid Nanoflowers and Their Applications in Biocatalysis.

In recent years, organic-inorganic hybrid nanoflower technology has become an effective method for enzyme immobilization. Here, seven hierarchical flower-like hemoglobin-phosphate organic-inorganic hybrid nanomaterials (Hb-M3(PO4)2·nH2O HNFs) were synthesized through an improved universal one-pot wet-chemical method, with Ca2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+ and Zn2+ as inorganic components. In this synthesis process, the metal cations are successively involved in the coordination reaction with Hb and the metathesis reaction to generate phosphate precipitation. The coordination ability of metal cations and the generation rate of phosphate precipitations were evaluated, then the progress of the two chemical reactions was controlled synchronously by adjusting the phosphate buffer (PB) concentration, and finally a flower-like structure conducive to substrate diffusion and transport was obtained. Due to the conformational transformation of hemoglobin and the abundant Cu2+/Fe3+ active sites, the hemoglobin-Cu3(PO4)2·3H2O nanoflowers have extremely high catalytic activity, which is ∼14 times that of Hb. Importantly, this method is suitable for the monometallic-ionic, polymetallic-ionic and polyvalent metal-ion nanoflowers, which broadens the chemical composition and structural diversity of nanoflowers.

Mesoporous Carbon-Based Materials for Enhancing the Performance of Lithium-Sulfur Batteries.

The most promising energy storage devices are lithium-sulfur batteries (LSBs), which offer a high theoretical energy density that is five times greater than that of lithium-ion batteries. However, there are still significant barriers to the commercialization of LSBs, and mesoporous carbon-based materials (MCBMs) have attracted much attention in solving LSBs' problems, due to their large specific surface area (SSA), high electrical conductivity, and other unique advantages. The synthesis of MCBMs and their applications in the anodes, cathodes, separators, and "two-in-one" hosts of LSBs are reviewed in this study. Most interestingly, we establish a systematic correlation between the structural characteristics of MCBMs and their electrochemical properties, offering recommendations for improving performance by altering the characteristics. Finally, the challenges and opportunities of LSBs under current policies are also clarified. This review provides ideas for the design of cathodes, anodes, and separators for LSBs, which could have a positive impact on the performance enhancement and commercialization of LSBs. The commercialization of high energy density secondary batteries is of great importance for the achievement of carbon neutrality and to meet the world's expanding energy demand.

Risk factors of recurrent choledocholithiasis following therapeutic endoscopic retrograde cholangiopancreatography.

BACKGROUND: The risk factors for the recurrent choledocholithiasis after endoscopic retrograde cholangiopancreatography (ERCP) have not been well studied. The aim of this study was to explore the risk factors of recurrent choledocholithiasis. METHODS: We carried out a retrospective analysis of data collected between January 1, 2010 and January 1, 2020. Univariate analysis and multivariate analysis were used to explore the independent risk factors of recurrent choledocholithiasis following therapeutic ERCP. RESULTS: In total, 598 patients were eventually selected for analysis, 299 patients in the recurrent choledocholithiasis group and 299 patients in the control group. The overall rate of recurrent choledocholithiasis was 6.91%. Multivariate analysis showed that diabetes [odds ratio (OR) = 3.677, 95% confidence interval (CI): 1.875-7.209; P < 0.001], fatty liver (OR = 4.741, 95% CI: 1.205-18.653; P = 0.026), liver cirrhosis (OR = 3.900, 95% CI: 1.358-11.201; P = 0.011), history of smoking (OR = 3.773, 95% CI: 2.060-6.908; P < 0.001), intrahepatic bile duct stone (OR = 4.208, 95% CI: 2.220-7.976; P < 0.001), biliary stent (OR = 2.996, 95% CI: 1.870-4.800; P < 0.001), and endoscopic papillary balloon dilation (EPBD) (OR = 3.009, 95% CI: 1.921-4.715; P < 0.001) were independent risk factors of recurrent choledocholithiasis. However, history of drinking (OR = 0.183, 95% CI: 0.099-0.337; P < 0.001), eating light food frequently (OR = 0.511, 95% CI: 0.343-0.760; P = 0.001), and antibiotic use before ERCP (OR = 0.315, 95% CI: 0.200-0.497; P < 0.001) were independent protective factors of recurrent choledocholithiasis. CONCLUSIONS: Patients with the abovementioned risk factors are more likely to have recurrent CBD stones. Patients who eat light food frequently and have a history of drinking are less likely to present with recurrent CBD calculi.

Comparison of tropomyosin released peptide and epitope mapping after in vitro digestion from fish (Larimichthys crocea), shrimp (Litopenaeus vannamei) and clam (Ruditapes philippinarum) through SWATH-MS based proteomics.

Tropomyosin (TM) is a major shellfish allergen and a minor fish allergen. Different digestion profiles affect potential allergen anaphylaxis of protein. In this study, released peptides of fish-TM, shrimp-TM, and clam-TM by in vitro digestion of simulated gastric fluid (SGF), simulated intestinal fluid (SIF), and gastrointestinal (GI) were analyzed using sequential windowed acquisition of all theoretical fragment ion mass spectra (SWATH-MS) based proteomics. Results showed that digestion products of shrimp-TM yielded a lot of peptides matched T/B cell epitopes while core regions matched epitopes were distributed along the entire chain. Pepsin or trypsin-based digestion products of shrimp-TM presented many more peptides matched T/B cell epitopes compared with those of fish-TM and clam-TM. Besides, a differentiating peptide of VEKDKALSNAEGEVAAL (72-88) overlapped T/B cell epitopes could be used as a candidate peptide marker to identify tropomyosin allergen. These findings would supply new insight into the different allergenicity of tropomyosin.

Suppress Loss of Polysulfides in Lithium-Sulfur Battery by Regulating the Rate-Determining Step via 1T MoS2-MnO2 Covering Layer.

The commercialization of lithium-sulfur batteries (LSBs) is obstructed by several technical challenges, the most severe of which is the irreversible loss of soluble polysulfide intermediates. These soluble polysulfides must be anchored or confined in the cathode side to maintain the long life of the LSBs. Here, 1T MoS2-MnO2/CC heterostructure functional covering layer is designed to regulate the rate-determining step from the liquid-to-solid reaction to solid-to-solid reaction. Rapid and uniform nucleation of solid Li2S2/Li2S is therefore achieved, and the loss of soluble polysulfides is retarded. The Li-S batteries assembled with 1T MoS2-MnO2/CC covering layer therefore deliver outstanding rate capabilities even under high sulfur loads and large current rates. This study paves a novel way to suppress the polysulfides' "farewell effect" from the perspective of the kinetics.

Nanoarray Architecture of Ultra-Lithiophilic Metal Nitrides for Stable Lithium Metal Anodes.

Lithium metal anode (LMA) is puzzled by the serious issues corresponding to infinite volume change and notorious lithium dendrite during long-term stripping/plating process. Herein, the transition metal nitrides array with outstanding lithiophilicity, including CoN, VN, and Ni3 N, are decorated onto carbon framework as "nests" to uniform Li nucleation and guide Li metal deposition. These transition metal nitrides with excellent conductivity can guarantee the fast electron transport, therefore maintain a stable interface for Li reduction. In addition, the designed multi-dimensional structure of metal nitride array decorated carbon framework can effectively regulate the growth of Li metal during the stripping/plating process. Of note, attributing to the lattice-matching between CoN and Li metal, the composite Li/CoN@CF anode exhibits ultra-stable cycling performance in symmetrical cells (over 4000 h@1 mA cm-2 with 1 mAh cm-2 and 1000h@20 mA cm-2 with 20 mAh cm-2 ). The assembled full cells based on Li/CoN@CF composite anode, LiFePO4 or S as cathodes, deliver excellent cycling stability and rate capability. This strategy provides an effective approach to develop a stable lithium metal anode for lithium metal batteries.

Research advances in vaccines against coxsackievirus group B / 中华微生物学和免疫学杂志

Coxsackievirus group B (CVB) belongs to human enterovirus and contains six serotypes. CVB infection in humans usually causes mild symptoms, but can lead to myocarditis, pancreatitis, hand, foot and mouth disease and central nervous system diseases, which is extremely harmful to infants and young children. There are outbreaks of CVB in many places at home and abroad. The epidemic patterns of different serotypes are distinct and complicated. Currently, there are no effective drugs or means to treat or prevent CVB infection. Vaccine is expected to be a cost-effective way to address CVB-related public health concerns. Although there is no CVB vaccine on the market, many institutions are conducting preclinical studies of various types of CVB vaccines, including nucleic acid vaccines, viral vector vaccines, recombinant protein vaccines, live-attenuated vaccines and inactivated vaccines. This article reviewed the advances in the research of CVB vaccines.

Stability of vitamin A, E, C and thiamine during storage of different powdered enteral formulas.

In this study, two different kinds of commercial enteral formulas were selected to evaluate the changes of vitamin A, E, C and thiamine during the different storage conditions of different temperature and relative humidity (60 ± 1 °C, 60 ± 5% for 5 and 10 days; 37 ± 1 °C, 75 ± 5% for 1, 2, 3, 5 and 6 months; 25 ± 1 °C, 60 ± 5% for 3, 6, 9, 12, 18 and 24 months). The results showed that as the temperature or time increased, the content of vitamin A, E and thiamine was gradually decreased whilst the level of vitamin C remained stable. The vitamins exhibited more stability at the storage of 25 ± 1 °C, RH 60 ± 5%. Vitamin A and thiamine decreased more in the polymeric formula (EFA) than that in the oligomeric formula (EFB), while, vitamin E decreased less in EFA than that in EFB. The kinetics of vitamin A, E and thiamine degradation during storage followed first order kinetic equations. Furthermore, the final levels of vitamins were higher than the minimum level recommended by legislation.

Pressurized N2 directly fed to the RuAu/CeO1.76 catalyst porous electrode in a proton exchange membrane electrolyzer favoring electrochemical NH3 production.

The limited N2 solubility in the present aqueous electrolyte critically restricts the selectivity and activity of environment-friendly electrochemical NH3 production at high current density. Here we developed a high-performance electrolyzer for the electrochemical N2 reduction reaction (eNRR) using amorphous RuAu clusters anchored on CeO1.88 nanorods with rich oxygen vacancies (OVs) as the catalyst and a proton exchange membrane (PEM) as the solid-state electrolyte, in which N2 is directly delivered to the electrode across a gas diffusion layer. The PEM electrolyzer achieved a remarkable NH3 yield rate of 185.53 µg mg-1 h-1 at -0.3 V vs. RHE under an applied N2 pressure of 4 bar, which is 5 times higher than that in aqueous electrolyte.

Quantifying the spatial pattern of urban heat islands and the associated cooling effect of blue-green landscapes using multisource remote sensing data.

Surface urban heat islands (SUHIs) are a global concern. Although their spatial pattern and the cooling effect of blue-green landscapes have been documented, exploring more accurate and quantitative results is still necessary. For Hangzhou, we combined nighttime light (NTL) data with LST images to investigate the spatial morphology of SUHIs and analyze the cooling effect of blue-green landscapes. The radiative transfer equation (RTE) method was used to derive the land surface temperature (LST). Then, based on the unique feature of Luojia1-01 NTL data, the concentric zone model (CZM) was proposed to depict the urban spatial structure. The CZM was applied to construct a number of equal-area concentric belts along the urban-rural gradient to determine the SUHI range and the corresponding blue-green landscape cooling effects. Finally, local Moran's I indices were adopted to identify the cold-hot spots of the SUHI and the relationship with land use. The minimum, average and maximum LSTs were 21.81 °C, 32.79 °C and 44.79 °C, respectively. Additionally, 59.16 % of the study area was affected by the SUHI, and the mean LST inside the SUHI was 36.4 °C, clearly higher than that of the rural area. The SUHI hotpots were clustered in regions with intensive human activities, forming archipelagos. Due to the different blue-green landscape densities, the cooling capacity had spatial heterogeneity in different urban rural belts (URBs), and the cooling capacity of URB16 was approximately 71 times that of URB1. The cooling efficiency increased with blue-green landscape density in general; hence, blue-green landscape density thresholds of 40 % and 70 % were recommended in the urban planning of different urban function zones. Relating the pattern of NTL data to LST images provide meaningful insight into the spatial pattern of SUHIs and the optimization of urban planning.

Concentrated fish oil ameliorates non-alcoholic fatty liver disease by regulating fibroblast growth factor 21-adiponectin axis.

OBJECTIVES: The fibroblast growth factor 21 (FGF21)-adiponectin axis participates in energy hemostasis and obesity-related syndrome. The present study aimed to investigate whether concentrated fish oil (FO) intervention could alleviate non-alcoholic fatty liver disease (NAFLD) via the regulation of the FGF21-adiponectin axis. METHODS: In a randomized controlled trial, 61 patients with NAFLD, age 55.9 ± 15.6 y, were randomly divided into two groups: FO (3 g/d; n = 30) and corn oil (CO; 3 g/d; n = 31), which served as the control group. RESULTS: After a 3-mo intervention, there were significant net reductions in serum alanine transaminase (-5.4 ± 14.5 U/L vs. -0.25 ± 4.70 U/L; P = 0.001) and triacylglycerol (-0.70 ± 1.10 mmol/L vs. 0.11 ± 1.04 mmol/L; P = 0.018) levels in the FO group compared with the CO group. Furthermore, the mean changes of FGF21 levels (-16.3 ± 20.1 pg/mL vs. 7.2 ± 32.9 pg/mL; P = 0.002) were significantly decreased, but adiponectin levels (1.14 ± 1.53 µg/mL vs. -0.42 ± 2.04 pg/mL; P = 0.011) were significantly increased in the FO group compared with the CO group. In the animal study, the mice fed the high-fat diet demonstrated characteristics of NAFLD. The administration of FO significantly improved high-fat diet-induced hepatic steatosis, insulin resistance, and inflammation compared with the high-fat control group. In addition, FO improved the sensitivity of FGF21, and stimulated the expression levels of adiponectin in the liver. CONCLUSIONS: The present study suggested that FO could potentially ameliorate NAFLD through mediating the FGF21-adiponectin axis.

Enhanced formation of iodinated trihalomethanes in a mixed chlorine/chloramine system and attenuation by UV-activated process.

Iodinated trihalomethanes (I-THMs) have drawn increasing concerns due to their higher toxicity than those of their chlorinated and brominated analogues. In this study, I-THM formation was firstly evaluated for three treatment scenarios - (i) chlorine alone, (ii) chloramine alone, and (iii) mixed chlorine/chloramine - in the presence and absence of UV irradiation for the iodide-containing humic acid solution or natural water. The results indicated that I-THM formation decreased in the order of mixed chlorination/chloramination > chloramination > > chlorination, which fitted the trend of toxicity evaluation results using Chinese hamster ovary cells. Conversely, total organic halide concentration decreased in the order of chlorination > > chloramination ≈ mixed chlorination/chloramination. Besides, I-THM formation can be efficiently controlled in a UV-activated mixed chlorine/chloramine system. Influencing factors including pH values and Br-/I- molar ratios were also systematically investigated in a mixed chlorine/chloramine system. Enhanced I-THM formation was observed with increasing pH values (6.0-8.0) and Br-/I- molar ratios (1: 1-10: 1). The results obtained in this study can provide new insights into the increasing risk of I-THM formation in a mixed chlorine/chloramine system and the effective control of I-THMs in the iodide-containing water using UV irradiation.

The effects of fish oil plus vitamin D3 intervention on non-alcoholic fatty liver disease: a randomized controlled trial.

PURPOSE: The present study aimed to investigate fish oil plus vitamin D3 (FO + D) supplementation on biomarkers of non-alcoholic fatty liver disease (NAFLD). METHODS: In a 3-month randomized controlled trial, 111 subjects with NAFLD, aged 56.0 ± 15.9 y, were randomized into FO + D group (n = 37), fish oil group (FO, n = 37) or corn oil group (CO, n = 37). The subjects consumed the following capsules (3 g/day), which provided 2.34 g/day of eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) + 1680 IU vitamin D3 (FO + D group), or 2.34 g/day of EPA + DHA (FO group), or 1.70 g/d linoleic acid (CO group). RESULTS: Using multivariable-adjusted general linear model, there were significant net reductions in serum alanine aminotransferase (ALT), and triacylglycerol (TAG) and TNF-α levels in the FO + D and FO groups, compared with the control group (P < 0.05). The supplemental FO + D also showed significant reductions in insulin (- 1.58 ± 2.00 mU/L vs. - 0.63 ± 1.55 mU/L, P = 0.050) and IL-1ß (- 6.92 ± 7.29 ng/L vs. 1.06 ± 5.83 ng/L, P < 0.001) in comparison with control group. Although there were no significant differences between FO + D and FO groups regarding biochemical parameters, supplemental FO + D showed decreases in ALT (from 26.2 ± 13.5 U/L to 21.4 ± 9.6 U/L, P = 0.007), aspartate aminotransferase (AST, from 22.5 ± 7.0 U/L to 20.2 ± 4.0 U/L, P = 0.029), HOMA-IR (from 3.69 ± 1.22 to 3.38 ± 1.10, P = 0.047), and TNF-α (from 0.43 ± 0.38 ng/L to 0.25 ± 0.42 ng/L, P < 0.001) levels following the intervention. CONCLUSION: The present study demonstrated that groups supplemented with FO + D and FO had similar beneficial effects on biomarkers of hepatocellular damage and plasma TAG levels in subjects with NAFLD, while in the FO + D group, there were some suggestive additional benefits compared with FO group on insulin levels and inflammation.
