Methods: The intervention involved administering polyphenol extract at a dose of 400 mg/kg body weight per day to mice on a high-fat diet. The mice were orally gavaged continuously for 4 weeks, and various parameters such as body weight, liver index, histomorphological changes in white fat and liver tissues, serum biochemical markers, organ antioxidant capacity, and intestinal barrier function were examined. Results: In comparison to control group (CON), the MODEL group (MODEL) exhibited significantly (P

Objective To evaluate the causal relationships between lipids (low - density lipoprotein cholesterol, high 一 density lipoprotein cholesterol [HDL - C], triglyceride [TG], apolipoprotein A - I [ApoA - I], apolipoprotein B) and non - alcoholic fatty liver disease (NAFLD) through a two - sample Mendelian randomization (MR) study. Methods Summary datasets of genome - wide association studies of lipids and NAFLD in European ancestry were leveraged, and single nucleotide polymorphisms associated with lipids were selected as instrumental variables. Several univariable MR analyses were conducted, including inverse - variance weighting method, MR 一 Egger regression, weighted median estimation, MR pleiotropy residual sum and outlier method. A multivariable inverse 一 variance weighting method was further used to evaluate the independent causal effect of lipids on NAFLD. Results Univariable inverse - variance weighting MR showed that genetically predicted higher HDL - C (OR 二 0. 774, 95% CI: 0.708 - 0. 845, P < 0. 001) and ApoA - I (OR 二 0. 878, 95% CI: 0. 796 - 0. 968, P -0. 009) were associated with a lower risk of NAFLD, while genetically predicted higher TG (OR = 1. 323, 95% CI: 1. 201 - 1. 458, P <0. 001) was associated with a higher risk of NAFLD. The causal effects of HDL 一 C and TG on NAFLD remained consistent in multivariable MR when adjusting for other lipids, body mass index, and type - 2 diabetes. Conclusion Our study supports a putative causal relationship between HDL - C, TG, and NAFLD.. [ABSTRACT FROM AUTHOR]

Objective To investigate the liver and renal function, blood lipids, and blood glucose at 3 months after blood donation in long-term blood donors aged 45-65 years, as well as the possibility of continuing to donate blood after exceeding the age for blood donation. Methods The long-term blood donors who donated blood at our station from September to December 2016 were selected, and according to the age, they were divided into group A (45-49 years of age), group B (50-54 years of age), group C (55-59 years of age), and group D (60-65 years of age). Liver and renal function, blood glucose, and blood lipid levels were measured at 3 months after the most recent blood donation and were compared between groups. Results There was a significant difference in the serum level of low-density lipoprotein cholesterol (LDL-C) at 3 months after blood donation between groups A/B/C and group D (t=2.45-4.61,P0.05). Conclusion The long-term blood donors, aged 45-59 years, tend to have stable liver and renal function, blood lipids, and blood glucose at 3 months after blood donation, and long-term blood donation does not affect the above indicators. The blood donors aged 60-65 years have a higher level of LDL-C after blood donation, with other indicators remaining stable, and therefore, they may be considered as potential blood donors.

Aim To investigate the mechanism of perilipin 2 (PLIN2) increasing lipid accumulation in macrophages. Methods The experiments were divided into oxidized low density lipoprotein (ox-LDL) group, different PLIN2 expression groups, and different activity Rab18 groups, the levels of Rab18 and acyl-CoA long chain synthetase 3 (ACSL3) protein in high expression and silent expression of PLIN2 macrophages were measured, and the levels of PLIN2, Rab18, and ACSL3 protein expression in high expression PLIN2 macrophages with different activity Rab18 were measured. Western blot was used to detect protein expression levels, immunofluorescence was used to observe the localization of intracellular related proteins, and oil red O staining was used to observe intracellular lipid accumulation. Results The expression levels of Rab18 and ACSL3 in cells with high expression of PLIN2 were increased significantly (P<0. 05), and there was an intracellular phenomenon of co-localization of PLIN2 with Rab18 and ACSL3. The expression level of ACSL3 in high expression macrophages of PLIN2 after transfection with the Rab18 dominant mutant Q67L plasmid (Rab18 activity increased) was increased significantly (P<0. 05), and the number of intracellular lipid droplets was also increased significantly (P < 0. 05). Conclusion PLIN2 promotes macrophage lipid accumulation through Rab18 by up-regulating ACSL3. [ABSTRACT FROM AUTHOR]

Lipid metabolism plays an important role in plant response to abiotic stress. Four salt/alkali-tolerant phosphate-solubilizing bacteria strains (W5, Y7, Y14 and Y31, with Latin names of Bacillus siamensis, Pseudo-monas sp., B. wiedmannii and Acinetobacter sp., respectively) screened in the previous study were used for soybean pot experiment to investigate the effects of phosphate-solubilizing bacteria (PSB) on the growth of soybean plants under salt/alkali conditions, and to analyze the changes of lipid compounds in soybean leaves. The results showed that the chlorophyll content, plant height, root length, shoot fresh weight, shoot dry weight, root fresh weight and root dry weight of soybean were increased after treatment with the four strains, and the Y7 strain treatment group had the best effect. The Y7 strain treatment group was selected for soybean leaf lipid metabolism analysis. It showed that a total of 429 lipids were detected, and 30 significantly different metabolites (16 up-regulated and 14 down-regulated) were screened in the Y7 strain treatment group. The metabolic pathways with the largest enrichment of differential metabolic pathways were glyceride metabolism from lipid metabolism, in which the content of diglyceride (DG) was significantly increased, the content of triglyceride ( TG) was significantly decreased, and the total content of phosphatidylethanolamine (PE), phosphatidylcholine (PC) and phosphatidylserine ( PS) was significantly increased, and the total content of phosphatidic acid (PA) and phosphatidylinositol (PI) total compounds was significantly decreased. The comprehensive results showed that salt/alkali-tolerant phosphate-solubilizing bacteria applied to salt/alkali soil had obvious growth promotion effect on soybean and affected soybean leaf lipid metabolic pathways and products.

Atherosclerosis is an important factor in cardiovascular events. Relevant epidemiological surveys show that the burden of atherosclerotic cardiovascular disease in China has increased rapidly and significantly in recent years, which has brought major challenges to China􀆳s public health problems. Myocardin-related transcription factor-A (MRTFA) plays an important role in the development of atherosclerosis, including participating in inflammatory responses, promoting lipid accumulation, and phenotypic transformation of vascular smooth muscle cells (VSMC) in the process of atherosclerosis, and exploring the correlation between MRTF-A and atherosclerosis is of great significance for finding new therapeutic targets. This article reviews the role of MRTF-A in the process of atherosclerosis lesions, which can provide a reference for targeted therapy of coronary atherosclerosis. [ABSTRACT FROM AUTHOR]

Herein, we used an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) system to investigate changes in the profile of non-volatile metabolites in green tea after different periods (15, 40, 80 and 120 days) of storage at 37 ℃. The color of green tea and tea infusion changed after 40 days of storage at 37 ℃ when compared with the control (stored at −80 ℃). During 40 days of storage, the content of catechins did not significantly change, but the content of free amino acids significantly decreased. A total of 684 non-volatile components were identified, 77 of which were found to be characteristic differential metabolites, the major ones being polyphenols, lipids and organic acids. The content of octadecadien-6-ynoic acid, an umami-related compound, significantly decreased after 40 days and was undetected after 80 days. The content of theaflavine-3-catechin, related to the color and taste of tea infusion, significantly increased with storage time. Similarly, the content of flavone glycoside increased with storage time. Moreover, the content of lipids such as triacylglycerols (TAGs) and diacylglycerol (DAGs) changed significantly after 15 days, and the content of free fatty acids increased with storage time. The findings from this study showed that the contents of lipids and flavonoids in green tea significantly changed during storage, which played an important role in the quality deterioration of green tea.

为探究香榧果实生长后期油脂及脂溶性活性物质的动态变化规律，以20年生香榧为研究对象，分析测定了香榧果实生长后期种仁中油脂含量、香榧籽油中脂肪酸组成及脂溶性活性物质（角鲨烯、菜油甾醇、豆甾醇、β-谷甾醇、α-生育酚、β-生育酚）的动态变化规律，构建了香榧果实生长后期香榧籽油中脂溶性活性物质的动态积累模型。结果表明：在香榧果实生长后期种仁中油脂含量由（35.65±0.02）%增长为（54.50± 0.01）%，脂肪酸组成比例变化显著，其中油酸增幅最大；角鲨烯和植物甾醇含量呈下降趋势，生育酚呈增长趋势，完熟前变化趋势均变缓；香榧果实生长过程中香榧籽油中角鲨烯、豆甾醇、β-谷甾醇含量的动态积累模型符合倒数函数方程，菜油甾醇及生育酚含量的动态积累模型符合多项式函数方程。综上，香榧果实生长后期，种仁中油脂含量增加，脂溶性活性成分均处于动态变化中。 In order to investigate the dynamic changes of oils and liposoluble active substances in Torreya grandis at late growth stage, the 20-year-old T.grandis was taken as the research object, the dynamic changes of oil content of T.grandis kernel and fatty acid components and liposoluble active substances (including squalene, campesterol, stigmasterol, β -sitosterol, α-tocopherol and β -tocopherol) in the oils at late growth stage were analyzed and determined, and the dynamic accumulation model of liposoluble active substances in oil was established. The results showed that the oils content of T.grandis kernel increased from (35.65±0.02)% to (54.50± 0.01)% at the late growth stage, and the composition and content of fatty acids in the oils changed significantly, in which oleic acid increased the most. The contents of squalene and phytosterol showed a decreasing trend, while tocopherol showed an increasing trend and the change trend slowed down before full maturity. The dynamic accumulation model of squalene, stigmasterol and β-sitosterol contents fit the reciprocal function equation, while the dynamic accumulation model of campesterol and tocopherol contents fit the polynomial function equation. In summary, all the liposoluble active substances dynamic change with the increase of oil in the late stage of T.grandis kernel growth.

Due to the consumption characteristics of rice and the requirements of the national grain strategic reserve, rice storage is a necessary means to ensure food security. Lipids are an important nutritional component of rice and have an important impact on rice quality. The degradation of lipids during rice storage is the major reason for the deterioration of rice quality. In this article, the distribution, existing forms, structures and composition of lipids in rice, the effect of lipid degradation on the eating quality of rice, and the methods used to stabilize and detect lipids are summarized, which will provide a theoretical basis for further research and regulation of lipid degradation and quality deterioration inhibition during rice storage.

The effect of the removal of starch granule-associated proteins (SGAPs) and/or lipids on pasting and in vitro digestion properties of adlay starch was investigated. The results showed that the removal of both SGAPs and lipids increased the swelling power, solubility, and rapidly digestible starch (RDS) and slowly digestible starch (SDS) contents and decreased the ratio of peak intensities at 1 045/1 022 cm-1, peak viscosity, trough viscosity, breakdown viscosity and resistant starch (RS) content. The removal of SGAPs significantly increased the gelatinization transition temperature and the gelatinization enthalpy and significantly decreased the onset gelatinization temperature. The effect of the removal of SGAPs on the short-range ordered structure and digestibility of adlay starch was more pronounced than that of the removal of lipids. The thermal properties of adlay starch were not significantly affected by the removal of lipids, and the crystal type was not significantly affected by the removal of SGAPs and lipids. The results have potential value for understanding the starch characteristics of adlay and for the application of adlay starch in food processing.

Biotic stresses (as pests, diseases, ect.) and abiotic stresses (as temperature stress and water stress ect.) are key factors affecting plant development and yield. Lipids participate in various pathways of plant response stress, forming a unique feedback response mechanism, including unsaturated fatty acids in disease and insect resistance in biological stress. In addition, fatty acid derivatives in abiotic stress could also increase intracellular osmotic regulation, reduce the degree of membrane lipid peroxidation and improve plant stress resistance. This paper summarizes the research progress on regulation mechanism of plant lipids under biological and abiotic stresses, briefly introduces stress types, and focuses on the changes and regulation of plant lipids under various stresses. It is expected to better understand on physiological activities of plants under different stresses, and to provide a basic theoretical reference for further research on lipids regulation on plant stress resistance.

Lipids, one of the important nutrients in foods, are a complex class of biomolecules, which play key roles in the processing of different biomolecules. Lipids affect the quality, nutrition and hygiene of foods, and are directly related to the occurrence of many chronic diseases. As an emerging discipline in omics, lipidomics is widely used in multiple fields including food science. With the continuous development and improvement of detection technologies, lipidomics technology is also being updated. This paper mainly introduces lipid classification and functions as well as lipidomics and its application in food science in order to provide a reference for the application of lipidomics technology in food science.

In order to explore the mechanism of flavor differences, the effect of two cooking methods, namely steaming and microwaving on the lipid composition, the degree of lipid oxidation and hydrolysis, and volatile substances in Penaeus vannamei was studied. The results showed that the contents of total lipids as well as phospholipids, triglycerides, and free fatty acids in P. vannamei were significantly reduced after cooking (P < 0.05). The lipid composition differed between steamed and microwaved shrimp. Microwaved shrimp had higher phospholipid contents but lower free fatty acid contents than the steamed one. The content of saturated fatty acids decreased markedly whereas the content of unsaturated fatty acids increased significantly after cooking (P < 0.05), which may be related to the hydrolysis of phospholipids. Steaming and microwave heating accelerated the oxidation and hydrolysis of lipids, resulting in a significant increase in acid value and thiobarbituric acid reactive substances (TBARS) value (P < 0.05). The results of electronic nose analysis showed that the odor characteristics of fresh, steamed and microwaved shrimp were significantly different, and the odor of fresh shrimp changed more after microwave heating. Twenty-five volatile substances were isolated and identified from shrimp meat using gas chromatography-ion mobility spectrometry (GC-IMS). Among these compounds, 2,3-glutaraldehyde, 2-butanone, 2-methyl butyraldehyde, hexanal, 1-octen-3-one and glutaraldehyde were the major flavor substances in cooked shrimp meat and their contents were higher in the microwaved sample. Pearson correlation analysis showed that oxidative hydrolysis of lipids made an essential contribution to the flavor formation of cooked shrimp and the free fatty acids C14:0, C15:0, C16:1, C18:1n9c, C18:2n6c and C18:3n3 were closely related to the formation of the characteristic odors of shrimp meat.

Objective From the perspective of lipid degradation, the effects of bisphenol F (BPF) exposure on lipolysis, fatty acid oxidation, and reactive oxygen species (ROS) levels in HepG2 cells were described. Methods HepG2 cells were used to construct an in vitro exposure model. The effects of BPF on the lipid degradation pathway were observed by realtime quantitative PCR, confocal microscopy, and Western blot. Results BPF exposure reduced the mRNA and protein expression of the rate-limiting enzymes, adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL), in HepG2 cells (P < 0.05). The mRNA and protein expressions of the fatty acid oxidation -related proteins, carnitine palmitoyl transferase 1α (CPT1α) and peroxisome proliferator -activated receptor α (PPAR α), were decreased (P < 0.05), and the ROS level from mitochondria was increased (P < 0.01). This caused the accumulation of lipid droplets. Conclusions BPF exposure reduced lipolysis and fatty acid oxidation in HepG2 cells and increased the level of ROS derived from mitochondria, which may be one of the important reasons for the occurrence of nonalcoholic fatty liver disease (NAFLD)- like changes.

Purpose This study aimed to investigate the correlation between the fat signal fraction (FF) of the fatdominant bone tissue of the knee joint, measured using the MRI Dixon method (DIXON) technique, and bone mineral density (BMD). Materials and Methods Among the patients who underwent knee DIXON imaging at our institute, we retrospectively analyzed 93 patients who also underwent dual energy X-ray absorptiometry within 1 year. The FFs of the distal femur metaphyseal (Fm) and proximal tibia metaphyseal (Tm) were calculated from the DIXON images, and the correlation between FF and BMD was analyzed. Patients were grouped based on BMD of lumbar spine (L), femoral neck (FN), and common femur (FT) respectively, and the Kruskal-Wallis H test was performed for FF. Results We identified a significant negative correlation between TmFF and FN-BMD in the entire patient group (r = -0.26, p < 0.05). In female patients, TmFF showed a negative correlation with FN-BMD, FT-BMD, and L-BMD (r = -0.38, 0.28 and -0.27, p < 0.05). In male patients, FmFF was negatively correlated with only FN-BMD and FT-BMD (r = -0.58 and -0.42, p < 0.05). There was a significant difference in the TmFF between female patients grouped by BMD (p < 0.05). In male patients, there was a significant difference in FmFF (p < 0.05). Conclusion Overall, we found that FF and BMD around the knee joints showed a negative correlation. This suggests the potential of FF measurement using DIXON for BMD screening. [ABSTRACT FROM AUTHOR]

[Objective] The study aims to investigate the effects of calcium on the growth and physiological characteristics of Camellia oleifera seedlings under aluminum stress, with a view to providing theoretical basis for revealing the physiological mechanism of calcium alleviation of aluminum stress in C. oleifera. [Method] The effects of different calcium concentrations (0, 0.5, 1.5, 3 and 5 mmol/L) applied under aluminum stress (4 mmol/L) on the growth, leaf photosynthesis, root osmoregulatory substances and antioxidant enzyme activities of C. oleifera seedlings were determined through a pot experiment. [Result] Aluminum stress inhibited the growth of C. oleifera seedlings significantly, and the application of 3 mmol/L calcium significantly alleviated the inhibition of aluminum growth in C. oleifera, and the plant dry weight increased by 40.58%. For photosynthetic parameters, aluminum stress reduced chlorophyll a, chlorophyll b, carotenoids and total chlorophyll contents of C. oleifera leaves. Net photosynthetic rate (Pn), stomatal conductance (Gs) and transpiration rate (Tr) decreased by 32.28%, 51.02% and 53.91%, respectively, compared with those under CK treatment, while intercellular CO2 concentration (Ci) increased by 20%. The addition of appropriate amount of calcium (1.5-3 mmol/L) significantly increased the photosynthetic pigment content, Pn, Gs and Tr, and decreased Ci of leaves. Compared with aluminum stress, calcium application could reduce the accumulation of root free proline and increased the soluble sugar content effectively. Under aluminum stress, the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) in the roots and ascorbate peroxidase (APX) in the leaves were significantly reduced. The plasma membrane permeability and malondialdehyde (MDA) content in the roots were significantly increased. Calcium application significantly enhanced antioxidant enzyme activities. POD and AXP activities were highest when the calcium concentration was 1.5 mmol/L, which were 35.13 and 234.11 U/g, respectively; and SOD and CAT activities were highest when the calcium concentration was 3.0 mmol/L, which were 533.20 and 48.42 U/g, respectively. Meanwhile, the addition of appropriate concentration of calcium (1.5-3 mmol/L) significantly reduced root plasma membrane permeability and MDA content, which were 19.52%-31.40% and 23.32%-27.86% lower than those under aluminum stress treatment, respectively. [Conclusion] Calcium at moderate concentrations (1.5-3 mmol/L) significantly improved photosynthetic capacity and antioxidant enzyme activity of C. oleifera leaves, reduced reactive oxygen stress and production of membrane lipid peroxidation products, and alleviated the toxic effects of aluminum stress on C. oleifera seedlings by regulating osmotic substances. However, when the calcium concentration reached 5 mmol/L, it inhibited the growth of C. oleifera seedlings. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect of Myriocin on high fat diet induced integrated stress response and further explore the mechanism. Methods A total of 18 ApoE-/- mice were fed a high- fat diet and randomly divided into control group (n = 9, phosphate buffer solution) and Myriocin group (n = 9, phosphate buffer solution + Myriocin). The drugs were administered orally for 12 weeks. Serum lipids [total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), very low density lipoprotein- cholesterol (VLDL-C) and high density lipoprotein-cholesterol (HDL-C)] were measured. Flow-cytometric analysis was used to determine the proportion of lymphocyte antigen 6 complex (Ly - 6c)high phenotype monocytes. HE staining was performed to compare the size and detailed composition of atherosclerotic plaques and immunofluorescence staining was used to observe the expression of monocyte chemotactic protein-1 (MCP-1). Real-time fluorescence quantitative polymerase chain reaction (PCR) was used to detect the mRNA expression levels of inflammation related molecules [including pro - inflammatory factors, interleukin-1β and 6 (IL-1β and IL-6), tumor necrosis factor-α (TNF-α), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), vascular endothelial growth factor (VEGF) and anti- inflammatory factor, IL-10]. In addition, the mRNA expression levels of integrated stress response related molecules [including glucose regulated protein 78 (GRP78), protein kinase R-like endoplasmic reticulum kinase (PERK), eukaryotic translation initiation factor 2 α (eIF2 α), activating transcription factor 4 and 6 (ATF4 and ATF6), endoplasmic reticulum stress - related apoptosis protein C/EBP homologous protein (CHOP) and Caspase12] were tested. The expression levels of integrated stress response related protein [including eIF2α, ATF4, inositol-requiring enzyme 1α (IRE1α) and phosphorylated IRE1α, p65 nuclear factor (p65 NF) and phosphorylated p65 NF, Caspase12 and cleaved Caspase12] were explored by Western blotting. Results 1) Treatment with Myriocin led to lower level of serum LDLC (t = 2.830, P = 0.012). 2) Myriocin suppressed monocytes differentiating toward a Ly-6chigh phenotype (t = 2.866, P = 0.011). 3) HE staining showed less atherosclerotic lesions at 200 and 300 μm distance away from the aortic valve (t = 2.281, P = 0.045; t = 3.506, P = 0.003) and less necrotic core areas (Z = - 2.870, P = 0.004) in the Myriocin group. 4) Immunofluorescence staining showed the reduction of MCP-1 protein expression in the Myriocin group; real-time fluorescence quantitative PCR showed that IL-1β mRNA (t = 3.968, P = 0.005), TNFα mRNA (t = 7.696, P = 0.000), ICAM mRNA (t = 3.294, P = 0.013), VCAM mRNA (t = 5.449, P = 0.001) and VEGF mRNA (t = 2.574, P = 0.037) were generally decreased in the Myriocin group, while IL-10 mRNA was increased (t = - 3.132, P = 0.017) in the Myriocin group. 5) Myriocin downregulated PERK mRNA (t = 4.174, P = 0.004-, eIF2α mRNA (Z = - 2.692, P = 0.007), ATF4 mRNA (t = 3.342, P = 0.012), ATF6 mRNA (t = 5.841, P = 0.001) and Caspase12 mRNA (t = 7.270, P = 0.000). 6) Western blotting showed that Myriocin suppressed the protein expression of eIF2α (t = 2.175, P = 0.047) and ATF4 (t = 2.923, P = 0.011), and the phosphorylation of p65 NF - B (t = 2.909, P = 0.011). Conclusions Myriocin could alleviate atherosclerosis progression of ApoE-/- mice by reducing integrated stress response and inflammatory response in the arterial walls. [ABSTRACT FROM AUTHOR]

In recent years, lung cancer has become the leading cause of cancer-related deaths. There is increasing evidence that many lipids and lipid analogs are key regulators of tumorigenesis, and factors that affect blood lipid levels such as smoking, diet, and obesity may be associated with cancer risk. With the deepening of research on the relationship between lipids and tumorigenesis, exploring the correlation between blood lipids and lung cancer risk and prognosis has become a research hotspot. This article reviews the research progress of the relationship between blood lipid levels and the risk of lung cancer, blood lipid levels and the prognosis of lung cancer patients, and the adjustment of blood lipid drugs and the prevention and treatment of lung cancer.

Ferroptosis is a recently recognized form of regulated cell death caused by an iron-dependent accumulation of lipid reactive species. However, little research on ferroptosis and lung cancer, one of the most common tumors, has been carried out. This paper tries to review the research progress of ferroptotic suppression and explain it from the different ways of ferroptosis occurrence. Furthermore, as inducing ferroptosis to treat cancer gets more attention, we introduce four kinds of ferroptosis-inducing compounds and new prospects for lung cancer therapy to provide new ideas for lung cancer treatment.
