Image1_Identification and verification of novel immune-related ferroptosis signature with excellent prognostic predictive and clinical guidance value in hepatocellular carcinoma.JPEG

Background: Immunity and ferroptosis often play a synergistic role in the progression and treatment of hepatocellular carcinoma (HCC). However, few studies have focused on identifying immune-related ferroptosis gene biomarkers.Methods: We performed weighted gene co-expression network analysis (WGCNA) and random forest to identify prognostic differentially expressed immune-related genes (PR-DE-IRGs) highly related to HCC and characteristic prognostic differentially expressed ferroptosis-related genes (PR-DE-FRGs) respectively to run co-expression analysis for prognostic differentially expressed immune-related ferroptosis characteristic genes (PR-DE-IRFeCGs). Lasso regression finally identified 3 PR-DE-IRFeCGs for us to construct a prognostic predictive model. Differential expression and prognostic analysis based on shared data from multiple sources and experimental means were performed to further verify the 3 modeled genes’ biological value in HCC. We ran various performance testing methods to test the model’s performance and compare it with other similar signatures. Finally, we integrated composite factors to construct a comprehensive quantitative nomogram for accurate prognostic prediction and evaluated its performance.Results: 17 PR-DE-IRFeCGs were identified based on co-expression analysis between the screened 17 PR-DE-FRGs and 34 PR-DE-IRGs. Multi-source sequencing data, QRT-PCR, immunohistochemical staining and testing methods fully confirmed the upregulation and significant prognostic influence of the three PR-DE-IRFeCGs in HCC. The model performed well in the performance tests of multiple methods based on the 5 cohorts. Furthermore, our model outperformed other related models in various performance tests. The immunotherapy and chemotherapy guiding value of our signature and the comprehensive nomogram’s excellent performance have also stood the test.Conclusion: We identified a novel PR-DE-IRFeCGs signature with excellent prognostic prediction and clinical guidance value in HCC.</p

DataSheet1_Association of PM2.5 With blood lipids and dyslipidaemia in a rural population of north-western china.docx

Background: Evidence regarding the association between particulate matter with aerodynamic diameter ≤2.5 μm (PM2.5) and blood lipid levels is insufficient in the rural areas of developing countries. Few studies have estimated the role of PM2.5 in blood lipid levels. We investigated the relationship between long-term exposure to PM2.5, blood lipids, and dyslipidaemia in rural Chinese adults.Methods: Baseline data of 15,802 participants (aged 35–74 years) in the China Northwest Cohort-Ningxia Project were used in this study. PM2.5 levels were assessed using satellite remote sensing data in accordance with each participant’s home address. Personally exposed PM2.5 was defined as the 3-year mean concentration prior to the baseline survey. Logistic and linear models were utilised to quantify the associations of PM2.5 with the prevalence of dyslipidaemia and with blood lipids, including total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C).Results: The 3-year mean level of PM2.5 was 35.36 ± 4.21 μg/m3. Every 1-μg/m3 increase in PM2.5 was related to an increase of 0.04% (95% CI: −0.44–0.53%) in TG and decreases of 0.37% (95% CI: 0.16–0.90%) in TC, 5.76% (95% CI: 5.32–6.21%) in LDL-C, and 0.89% (95% CI: 0.72–1.05%) in HDL-C. Every 1-μg/m3 increment in PM2.5 was related with a 4% (95% CI:3–5%) and 18% (95% CI:16–20%) higher risk of dyslipidaemia and hypoalphalipoproteinemia, respectively, and a decrease of 11% (95% CI:10–13%) in hyperbetalipoproteinemia. Sex, age, and BMI were adjusted for the relationships between PM2.5, blood lipids, and dyslipidaemia.Conclusion: Greater PM2.5 exposure was related to harmful changes in blood lipids and dyslipidaemia. Male, elderly, and overweight individuals may be more vulnerable to the negative effects of PM2.5.</p

Effect of Substituent Groups in Anions on Some Physicochemical Properties of 1‑Butyl-3-methylimidazolium Carboxylate Ionic Liquids

In this work, four 1-butyl-3-methylimidazolium carboxylate ionic liquids (ILs) with different substituent groups in anions, including 1-butyl-3-methylimidazolium glycollate [C₄mim]­[HOCH₂COO], 1-butyl-3-methylimidazolium lactate [C₄mim]­[CH₃CHOHCOO], 1-butyl-3-methylimidazolium benzoate [C₄mim]­[C₆H₅COO], and 1-butyl-3-methylimidazolium glycinate [C₄mim]­[H₂NCH₂COO], have been synthesized and characterized. Their densities (ρ) and surface tensions (γ) have been determined experimentally in the temperature range of (298.15 to 343.15) K. By using thermodynamic and empirical equations, molar volume (<i>V</i>_m), isobaric expansivity (α_<i>p</i>), standard entropy (<i>S</i>°), lattice energy (<i>U</i>_POT), surface excess entropy (<i>S</i>_s), vaporization enthalpy (Δ_l^g<i>H</i>_m⁰) and Hildebrand solubility parameter (δ_H) of these ILs have been derived from density and surface tension data. The effects of substituent groups in carboxylate anions on densities and surface tensions of these ILs have been assessed from the analysis of the structure–property relationship

Table_2_Trait anxiety affects attentional bias to emotional stimuli across time: A growth curve analysis.DOCX

Many studies have illustrated the close relationship between anxiety disorders and attentional functioning, but the relationship between trait anxiety and attentional bias remains controversial. This study examines the effect of trait anxiety on the time course of attention to emotional stimuli using materials from the International Affective Picture System. Participants with high vs. low trait anxiety (HTA vs. LTA) viewed four categories of pictures simultaneously: dysphoric, threatening, positive, and neutral. Their eye-movements for each emotional stimulus were recorded for static and dynamic analysis. Data were analyzed using a mixed linear model and growth curve analysis. Specifically, the HTA group showed a greater tendency to avoid threatening stimuli and more pupil diameter variation in the early period of stimulus presentation (0–7.9 s). The HTA group also showed a stronger attentional bias toward positive and dysphoric stimuli in the middle and late period of stimulus presentation (7.9–30 s). These results suggest that trait anxiety has a significant temporal effect on attention to emotional stimuli, and that this effect mainly manifests after 7 s. In finding stronger attentional avoidance of threatening stimuli and more changes in neural activity, as well as a stronger attentional bias toward positive stimuli, this study provides novel insights on the relationship between trait anxiety and selective attention.</p

Effect of Alkyl Chain Length in Anions on Thermodynamic and Surface Properties of 1-Butyl-3-methylimidazolium Carboxylate Ionic Liquids

Carboxylate-anion-based imidazolium ionic liquids (ILs) are powerful solvents for cellulose and lignin. However, little is known about their fundamental physicochemical properties. In this work, 1-butyl-3-methylimidazolium carboxylate ILs 1-butyl-3-methylimidazolium formate ([C₄mim]­[HCOO]), acetate ([C₄mim]­[CH₃COO]), propionate ([C₄mim]­[CH₃CH₂COO]), and butyrate ([C₄mim]­[CH₃(CH₂)₂COO]), in which the alkyl chain length in the anions is being varied in contrast to the more usual studies where alkyl chain length in the cations is varied, have been synthesized and their densities and surface tensions have been determined experimentally at different temperatures. By using these data, the molar volume, isobaric expansivity, standard entropy, lattice energy, surface excess entropy, vaporization enthalpy, and Hildebrand solubility parameter have been estimated for these ILs. From the analysis of structure–property relationship, the effect of alkyl chain length in the anions on these physicochemical properties of the ILs has been assessed and the dissolution of cellulose and lignin in these ILs has been discussed. Such knowledge is expected to be useful for understanding the nature of this class of solvent for the dissolution of biomacromolecules
