Beneficial effects of Omega-3 polyunsaturated fatty acids in treatment of non-alcoholic fatty liver disease in rats.

Nonalcoholic fatty liver disease (NAFLD) is sickness with different causes and it is the most hepatic illness. The objective of this work is to investigate the bimolecular changes in a model of high fat diet induced- NAFLD in rats. Also, the hypolipidemic, antioxidant and anti-inflammatory effects of omega-3 were clarify via evaluation of some biochemical and molecular parameters in the liver tissue of rats.Twenty one adult white albino rats were divided into three groups. Group I (Normal control): received no drugs and fed balanced diet, Group II (NAFLD- induced group): rats fed high fat diet for 8 weeks followed by normal basal ration for additional 8 weeks. Group III (NAFLD + omega-3): rats administrated omega-3 (300 mg/kg b.wt/day), orally for 8 weeks post-induction of NAFLD. The obtained results showed a significant increase in serum Total cholesterol and Triacylglycerols (TAG) concentrations, L-MDA and TAC in liver tissuewith significant up-regulation in CPT-1α, FAS, SREBP-1c, PPAR-α, Nrf2 and TAK1gene expression in NAFLD-induced rats. Treatment with Omega-3 to NAFLD induced rats potentially improved molecular hepatic cell function and oxidative alterations related to NAFLD near its normal ranges. Meanwhile, histo-pathological findings supported that Omeg-3 markedly attenuates harmful effects of NAFLD and protected liver cell. On conclusion, Omega-3 plays an important role as potent anti-oxidant, anti-obesity, anti-inflammatory via inhibition of hepatic steatosis and oxidative stress singling.

Relationship between AGT rs2493132 polymorphism and the risk of coronary artery disease in patients with NAFLD in the Chinese Han population.

ObjectiveTo investigate the relationship between angiotensin (AGT) rs2493132 gene polymorphism and the risk of developing non-alcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) in the Chinese Han population.MethodsPolymerase chain reaction was performed to determine AGT genotypes. Anthropometric and clinical data were investigated and statistically analyzed in the clinical laboratory department of Qingdao Municipal Hospital.ResultsThe AGT rs2493132 CT + TT genotype was an important risk factor for CAD in patients with NAFLD and NAFLD + CAD in healthy controls. The AGT rs2493132 T allele increased the risk of NAFLD + CAD in healthy controls. The AGT rs2493132 CT + TT genotype and T allele also significantly increased the risk of CAD in patients with NAFLD after adjustments for age, sex, and body mass index. In addition, AGT rs2493132 T allele carriers showed higher total cholesterol (TC) and low-density lipoprotein (LDL) levels compared with non-carriers.ConclusionsThe AGT rs2493132 CT + TT genotype and T allele significantly increased the risk of developing CAD in patients with NAFLD in the Chinese Han population. The AGT rs2493132 T allele was associated with increased serum TC and LDL levels.

Structural Characterization of Peptides From Huangjiu and Their Regulation of Hepatic Steatosis and Gut Microbiota Dysbiosis in Hyperlipidemia Mice.

Hyperlipidemia is a chronic disorder that is difficult to cure and usually treated with long-term lipid-reducing drugs. Recent trends have led to the use of diet therapies or food-derived strategies in the treatment of such long-term diseases. The Chinese rice wine (huangjiu) contains a wide range of bioactive peptides that are produced during the multi-species fermentation process. To clarify the regulation effects of lipid metabolism and gut microbiota by huangjiu bioactive peptides, three huangjiu peptides were isolated, purified and characterized by hyper-filtration, macroporous resin, gel filtration separation and structural identification. Meanwhile, a mouse model of high-fat diet-induced hyperlipidemia was established to study the effects of huangjiu peptides on serum biomarker, hepatic metabolism and gut microbiota dysbiosis. Experimental results showed that huangjiu peptides T1 and T2 (HpT1, HpT2) treatment alleviated the increase in serum total cholesterol, triglyceride, low-density lipoprotein cholesterol levels and aberrant hepatic lipid accumulation in the high-fat diet-induced hyperlipidemia mice. Furthermore, HpT2 and HpT1 restored the α-diversity and structure of gut microbial community after hyperlipidemia-induced microbiota disturbance compared with simvastatin and HpT3. The administration of HpT2 and HpT1 regulated the microbiota-mediated gut ecology through alterations of characteristic taxa including Lactobacillus, Ileibacterium, Faecalibaculum and Alloprevotella by linear discriminant analysis effect size analysis. Collectively, our results offer new insights into the abilities of food-derived peptides on alleviation of high-fat diet-induced hyperlipidemia, hepatic steatosis and gut dysbiosis in mice.

Effects of spray-dried bovine plasma protein in milk replacers fed at a high plane of nutrition on performance, intestinal permeability, and morbidity of Holstein calves

Spray-dried plasma protein (SDP) has been shown to improve growth and intestinal function in young calves when included in milk replacers (MR) fed at conventional rates. Use of an SDP and wheat protein blend to replace a portion of whey protein has been shown to perform similarly to using an all-whey protein control MR. However, a trend in the dairy industry is to feed calves for greater rates of growth during the preweaning period. The purpose of this study was to determine the effects of increasing amounts of SDP inclusion in MR on growth and health of calves fed at a high plane of nutrition. Young (<7 d) Holstein calves were offered starter and assigned to 1 of 5 MR treatments: an all-milk protein (whey) control MR (0SDP, n = 26) or MR containing 5% SDP (5SDP, n = 20), 7.5% SDP (7.5SDP, n = 14), 10% SDP (10SDP, n = 20), or 12% of an approximate 1:1 SDP plus wheat protein blend (PW, n = 17). All MR were formulated to contain 26% CP and 16% fat and were fed at a maximum rate of 1 kg of powder (as fed) from d 8 to 36. Amounts of MR powder were decreased by 25%/wk from d 37 to weaning at d 57. Thereafter, calves were provided only starter feed until the end of the study at d 63. On d 4, 15, 36, and 57, intestinal permeability was assessed via oral administration of lactulose and d-mannitol followed by analysis of lactulose and mannitol in blood at 60 min after administration. Increasing SDP led to a small linear decrease in MR consumed. There was a tendency for a positive linear relationship between increasing SDP and average daily gain of body weight, and SDP had mixed effects on body frame variables. Increasing SDP tended to increase fecal scores and increased the amount of fluid therapy given. Diet had no effect on intestinal permeability. Increasing SDP led to an increase in serum total cholesterol and serum urea N and tended to have a quadratic effect on serum glucose concentration on d 36. Calves fed PW tended to have increased withers height, increased intestinal permeability on d 36, and an increased likelihood of being medicated for any reason or being medicated for respiratory illness, but growth and health were not different from the control diet otherwise. Feeding PW led to an increase in serum total cholesterol and tended to lead to increased serum glucose concentration on d 36. Results of this study indicate that SDP can be included at up to 10% as fed in the MR of calves fed at a high plane of nutrition (1 kg/d of MR powder, as fed) with improvements in average daily gain. Additionally, a 1:1 SDP plus wheat protein blend can be used at 12% inclusion with no difference in most health and growth parameters.

The Effects of Exercise and Restriction of Sugar-Sweetened Beverages on Muscle Function and Autophagy Regulation in High-Fat High-Sucrose-Fed Obesity Mice.

BackgroundAutophagy maintains muscle mass and healthy skeletal muscles. Several recent studies have associated sugar-sweetened beverage (SSB) consumption with diseases. We investigated whether muscle dysfunction due to obesity could be restored by SSB restriction (SR) alone or in combination with exercise (EX) training.MethodsObese mice were subjected to SR combined with treadmill EX. Intraperitoneal glucose tolerance test, grip strength test, hanging time test, and body composition analysis were performed. Triglyceride (TG) and total cholesterol (TC) serum concentrations and TG concentrations in quadriceps muscles were analyzed. Western blot and reverse transcription-quantitative polymerase chain reaction helped analyze autophagy-related protein and mRNA expression, respectively.ResultsSR alone had no significant effect on fasting blood glucose levels, glucose tolerance, and muscle function. However, it had effect on serum TC, serum TG, and BCL2 interacting protein 3 expression. SR+EX improved glucose tolerance and muscle function and increased serum TC utilization than SR alone. SR+EX reduced P62 levels, increased glucose transporter type 4 and peroxisome proliferator-activated receptor γ coactivator-1α protein expression, and improved grip strength relative to the high-fat and high-sucrose liquid (HFHS) group, and this was not observed in the HFHS+EX group.ConclusionSR induced mitophagy-related protein expression in quadriceps, without affecting muscle function. And, the combination of SR and EX activated mitophagy-related proteins and improved muscle function.

41502 Does dietary fat composition predict short-term elevations in lipid levels in adults on a modified Atkins diet?

ABSTRACT IMPACT: Our work provides guidance on whether dietary fat intake influences serum cholesterol levels in response to ketogenic diet therapy in adults with epilepsy. OBJECTIVES/GOALS: The modified Atkins diet (MAD) is used in the management of drug-resistant epilepsy in adults. Some patients on MAD show an increase in serum levels of total cholesterol and low-density lipoprotein (LDL) cholesterol. We explored whether dietary fat composition predicts short-term elevations in serum lipid levels in diet-naive adults who begin MAD. METHODS/STUDY POPULATION: Participants self-reported their diet intake with 3-day food records at baseline, 1 month and 2 months. Food records were analyzed using Nutrition Data System for Research software. Fasting serum levels of total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and triglycerides were also collected and LDL level calculated at baseline, 1 month, and 2 months. RESULTS/ANTICIPATED RESULTS: 38 patients submitted complete food records at each study visit (baseline, 1 month, and 2 month). Compared to baseline diet intake, there was a significant reduction in daily carbohydrate intake at 1 and 2 months (p&lt;0.001) and a significant increase in daily fat intake at 1 and 2 months (p&lt;0.001). There was also a significant increase in daily saturated fatty acid (SFA) intake at 1 and 2 months (p&lt;0.001), daily mono-unsaturated fatty acid (MUFA) intake at 1 and 2 months (p&lt;0.001), and daily cholesterol intake at 1 month (p&lt;0.05) and 2 months (p&lt;0.001), but no change in daily poly-unsaturated fatty acid (PUFA) intake over time. Compared to baseline, there was a significant increase in serum LDL at 1 month (p&lt;0.001) and 2 months (p&lt;0.01) and an increase in serum TC at 1 month (p&lt;0.01) but not 2 months. DISCUSSION/SIGNIFICANCE OF FINDINGS: Despite a significant increase in total fat, saturated fat and mono-unsaturated fat intake as well as an increase in total cholesterol and LDL levels following MAD initiation, dietary fat composition appears to minimally predict serum lipid values in the short term.

Hepatoprotective effects of Quassia amara stem bark against cadmium-induced toxicity in male Wistar rats.

The liver is one of the primary biorepositories of cadmium (Cd) and it has been implicated in the pathogenesis of hepatic diseases. Quassia amara stem bark has been reputed to have strong antimalarial, antimicrobial, antiulcerative and amoebicidal properties. This study aims to determine the effects of Q.amara on Cd-induced hepatotoxicity and lipid profile in male Wistar rats. The animals were divided into three groups of five animals each. Group 1 served as control while group 2 received Cd (5mg/kg) for 4weeks. Prior to Cd treatment, group 3 was treated with Q.amara extract (200mg/kg) for 2weeks and received the Q.amara and Cd simultaneously for 4weeks. Cadmium caused significant increase in serum total cholesterol and low-density lipoprotein (LDL) as well as increased hepatic malondialdehyde (MDA) when compared with the control group. On the other hand, Cd caused a decrease in serum high-density lipoprotein (HDL) and hepatic superoxide dismutase (SOD) when compared with control. However, treatment with Q.amara prevented Cd-induced changes in the lipid profile, augmented Cd-induced decline in SOD and also ameliorated the Cd-induced increase in MDA. Catalase level was however comparable across the groups. Q.amara ameliorated the Cd-induced damage to liver by preventing dyslipidemia and oxidative damage in the hepatic tissue.

Effects of antiepileptic drugs on serum lipids profile among young adult Sudanese patient with epilepsy at Aljazeera State

consequences that lead to an increase in risk of atherosclerosis in patients with epilepsy, several studies have reported that the patients commonly used antiepileptic drugs like phenytoin, and carbamazepine increase serum total Cholesterol, High Density Lipoproteins Cholesterol (HDL-C) Low Density lipoprotein Cholesterol ( LDL-C ) levels and Triglyceride (TG) .The aim of this study to assess and compare serum lipid profile of young adult patients treated by anti-epileptic drugs (phenytoin, oxcarbazepine and valproic acid) . Materials and Methods a cross-sectional study was conducted in Aljazeera state. Epileptic patients were of recruited. and taking antiepileptic drugs for more than six months and on regular follow up; approximately 120 patients on commonly used antiepileptic drugs (40 on phenytoin, 40 on oxcarbazepine, 40 on valproic Acid). Age and sex matching 40 controls were taken. our results show significant difference in the of mean TC, TG, HDL, and LDL-C levels in the group receiving phenytoin for more than six months when compared with control group P value (0.00) for all lipid profile. Also significant difference between the mean of TC, TG, HDL-C and LDL-C levels in the group receiving oxcarbazepine for more than six months when compared with control P value (0.00 ) for all lipid profile. From the present study we concluded that CYP enzyme inducer anti-epileptic medicines like phenytoin and oxcarbazepine is strongly associated with increased levels of TC, LDL-C, HDL-C and TG, where asvalproate showed no significant change. Therefore, the serum cholesterol level should be regularly monitored in patients undergoing. Therapy with inducer anti-epileptic medicines.

Alteration of lipid metabolism, autophagy, apoptosis and immune response in the liver of common carp (Cyprinus carpio) after long-term exposure to bisphenol A

Bisphenol A (BPA), as a phenolic compound, is harmful to human health, and its residue in the aquatic environment also threatens the health of aquatic animals. In this research, the toxicity effects of BPA on liver tissues were evaluated in common carp (Cyprinus carpio) after long-term exposure. Fish were exposed to five concentrations of BPA (0, 0.01, 0.1, 0.5 and 2 mg/L) for 30 days. The blood and liver tissues were gathered to analyze biochemical indices and genes transcription levels. The data related to lipid metabolism showed that BPA exposure increased serum total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) levels, upregulated the expressions of fatp1, pparγ, fas, atgl, hsl, pparα, cpt1b, acox-1, and downregulated the expression of dgat1 in liver. Antioxidative parameters displayed a reduced antioxidant ability and increased lipid peroxidation after BPA exposure. Meanwhile, the upregulations of nrf2, ho-1, cyp1a and cyp1b genes revealed an adaptive response mechanism against oxidative stress-induced adverse effects. After 30 days of exposure, BPA induced apoptosis and endoplasmic reticulum stress (ERS) via upregulating the expression levels of apoptosis and ERS-related genes and increasing Ca2+ concentration in liver. Moreover, the downregulation of mtor and the upregulation of atg3, atg7, tfeb, uvrag and mcoln1 indicated that BPA could influence the normal process of autophagy. Furthermore, BPA exposure activated toll like receptors (TLRs) pathway to mediate the inflammatory response. Our results demonstrated that BPA exposure disturbed lipid metabolism, and induced oxidative stress, ERS, apoptosis, autophagy and inflammatory response in the liver of common carp. These findings contributed to the understanding of hepatotoxicity mechanism induced by BPA in fish.

Effect of a Herbal Formula Song Zhi Wan on Non-alcoholic Fatty liver Disease in Obese Mice

<i>Background</i>: Effective treatment against non-alcoholic fatty liver disease (NAFLD) is lacking. Song Zhi Wan (SZW), a Chinese formulation medicine comprising eight herbal ingredients, has been demonstrated to confer a liver protective effect in chronic hepatitis C patients. We aimed to investigate the effect of SZW on NAFLD using a high-fat diet (HFD; 60% fat) induced obese mouse model. <i>Methods</i>: C57BL/6J mice were fed with HFD for 10 weeks, followed by daily oral administration of various dosages of SZW (low [n=6], normal [n=10], high [n=10]) or water (n=10) for 8 weeks. Another formulation of SZW (modified SZW), in which two ingredients were replaced by radish seed and barley, was tested. Serum total cholesterol and triglyceride levels, liver transaminases, and histologic steatosis were assessed. <i>Results</i>: At the end of experiment, the HFD-fed placebo mice had a mean increase in serum total cholesterol and triglyceride by 57.7% and 35.0%, respectively. HFD-fed mice receiving either SZW formulation had a smaller increase in serum total cholesterol (mean increase 7.9% – 39.4%) and a significant reduction in triglyceride (mean reduction 4.2% – 27.4%; <i>P</i> < 0.05). A dosage dependent effect on serum total cholesterol and triglyceride was observed with modified SZW (=0.043 and 0.006, respectively). 90% of placebo mice and 59% of SZW-treated mice had severe steatosis (<i>P</i>=0.079). With an escalating dosage of original SZW, there was a decreasing proportion of mice with severe steatosis (<i>P</i>=0.013). <i>Conclusion</i>: SZW administration can attenuate hypercholesterolemia, reduce dyslipidemia and alleviate steatosis in HFD-induced obese mice.

Serum lipid abnormalities in migraine: A meta-analysis of observational studies.

The association of migraine with vascular comorbidities is long-established. The contribution of the "traditional" cardiovascular risk factors to this connection remains unclear. To determine-quantify the differences in the serum lipid concentrations between lipid-lowering agents-naïve individuals with migraine and healthy controls (HC). The study protocol was not preregistered with an online systematic review-protocol registry. A literature search involving MEDLINE, EMBASE, CENTRAL, Google Scholar, and the OpenGrey database was performed. Case-control, cross-sectional, or cohort studies involving HC and participants with migraine (with and without aura regardless of the use of prophylactic treatment) that quantitatively assessed serum low-density lipoprotein cholesterol (LDL-C) (primary index) and/or total cholesterol (TC) and/or high-density lipoprotein cholesterol (HDL-C) and/or triglycerides (TG) (secondary indices) were retrieved. Articles including participants with known dyslipidemia (or under lipid-lowering medications) or with secondary causes of dyslipidemia (aside from the subjectively assessed lifestyle parameters) were excluded. Studies with abstracts and full texts not published in English and articles reporting the implementation of other study designs (reviews, meta-analyses, commentaries, case reports, etc.) were excluded as well. Conference abstracts and English abstracts from studies with full texts not published in English were evaluated as part of the gray literature. Each step of the review process was performed by two investigators independently, and relevant data were abstracted based on standardized extraction forms. Any discrepancies were resolved by a third investigator. Seventeen studies (16 case-control and 1 cross-sectional) fulfilled the eligibility criteria. Retrieved articles involved adult participants, principally during the fourth decade of life. Results were compatible with higher LDL-C levels in migraine individuals (1370) than in HC (1215) [12 studies, mean difference (MD) = 10.4mg/dl, 95% confidence interval (CI) = (1.6, 19.2)]. Similarly, higher TC levels were determined in migraine patients [14 studies, migraine = 1325, HC = 1213, MD = 10.6mg/dl, 95% CI = (1.8, 19.3)], as were TG levels [15 studies, migraine = 1526, HC = 1262, MD = 11.8mg/dl, 95% CI = (3.6, 20.0)]. HDL-C concentrations were not different between the two groups [14 studies, migraine = 1488, HC = 1328, MD = -0.4mg/dl, 95% CI = (-2.2, 1.5)]. Prespecified sensitivity analysis following the exclusion of studies not presenting comparable body mass index values between the groups nullified the significant difference regarding LDL-C levels [MD = 5.3mg/dl, 95% CI = (-0.1, 10.8)]. Subgroup analyses as well as the direct comparison of migraine with aura and migraine without aura individuals were compatible with no difference regarding lipid concentrations, but only a small fraction of the retrieved studies presented relevant figures. Although our results are of limited generalizability, since most retrieved studies were performed in Turkey (nine studies), TC abnormalities may provide part of the explanation for the unfavorable cardiovascular profile of migraine patients. Lifestyle may be partly or entirely accountable for the determined increased serum TC. Additional studies that will completely address the effect that lifestyle parameters exert on lipid concentrations are required to better capture existing abnormalities.

Abstract 16851: Lipid Profile Differences Among Premenopausal and Postmenopausal African American Women and Implications for Treatment Per Guideline

Introduction: Postmenopausal women have an increased cardiovascular disease (CVD) risk compared to premenopausal women. Though literature demonstrates a relationship between abnormal CVD risk factor patterns, namely lipids, and menopause, less is known about this association in minority racial and ethnic groups. Examining this association in African Americans (AA) is important because they experience disproportionate CVD outcomes. Moreover, recent studies have shown that AA eligible for statin therapy were less likely to receive treatment. Hypothesis: Postmenopausal women are more likely to have a more abnormal lipid profile compared to premenopausal women. Methods: A cohort of 962 women (mean age 50 ± 14 years) from the 10,000 Women Project were categorized into self-declared premenopausal (n = 475, mean age 40 ± 9.8 years) and postmenopausal (n= 487, mean age 61 ± 9.1 years) groups. Data was obtained at community health screening events through self-declared health history surveys. Lipid profiles were obtained through a non-fasting point-of-care cholesterol test. Several CVD risk factors were compared among these groups that include serum total cholesterol (TC), low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL), triglycerides (TG), pooled cohort Atherosclerotic Cardiovascular Disease (ASCVD) 10-year risk of heart disease or stroke score, BMI, waist circumference, and blood pressure. Student’s T test was utilized for statistical analysis. Results: Cholesterol testing revealed a significant increase in serum TC (p &lt; 0.0001), LDL (p = 0.0001), and TG (p = 0.001) in the postmenopausal group compared to the premenopausal group. Interestingly, there was also a significant increase in serum HDL in the postmenopausal group (p = 0.0081). Additionally, the ASCVD risk score, which is heavily weighted on age, was significantly higher in the postmenopausal group compared to the premenopausal group (p &lt; 0.0001). Conclusion: Menopause is associated with a more abnormal lipid profile and an elevated ASCVD risk score in AA women which places this group at a higher risk of CVD. Prioritizing lipid management, by adhering to cholesterol treatment guidelines, may assist with CVD risk reduction in this high-risk group.

Association of the Types of Alcoholic Beverages and Blood Lipids: A Community-Based Study

Although light-to-moderate alcohol consumption is considered beneficial, alcohol in binge doses or high cumulative lifetime consumption leads to cardiovascular diseases, metabolic syndrome, and structural damage to various organs. Alcohol is known to alter blood lipid concentrations; however, the association of the types of alcohol, including the rice-based fermented alcohol, on the lipid profile has not been investigated extensively. We sought to determine the effects of cumulative lifetime consumption of Haria, an Indian rice-based fermented drink, Indian-made foreign liquor (IMFL), and a combination of the two on the blood lipid profiles of male participants from India. The effect of Haria alone on the blood lipids was also examined in the female group. A community-based study involving male (n = 86) and female (n = 31) participants, aged 20–60 from Jharkhand, India, was conducted to analyze the effect of different alcohol types on the levels of total serum cholesterol, triglyceride, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol. The male and female participants who regularly consumed rice-based fermented alcohol showed no alteration in their lipid profile. However, IMFL and combination of IMFL and Haria consumption were associated with increased serum total cholesterol, triglyceride, LDL levels (p < 0.05), and decreased HDL levels (p < 0.05). High cumulative lifetime consumption of rice-based fermented alcohol does not alter the blood lipid levels and appear as a safe alcoholic beverage. The consumption of other forms of alcohol, including whiskey, rum, brandy, and vodka, changed the blood lipid profile.

NR4A1 Deletion in Marginal Zone B Cells Exacerbates Atherosclerosis in Mice-Brief Report.

NR4A orphan receptors have been well studied in vascular and myeloid cells where they play important roles in the regulation of inflammation in atherosclerosis. NR4A1 (nerve growth factor IB) is among the most highly induced transcription factors in B cells following BCR (B-cell receptor) stimulation. Given that B cells substantially contribute to the development of atherosclerosis, we examined whether NR4A1 regulates B-cell function during atherogenesis. Approach and Results: We found that feeding Ldlr-/- mice a Western diet substantially increased Nr4a1 expression in marginal zone B (MZB) cells compared with follicular B cells. We then generated Ldlr-/- mice with complete B- or specific MZB-cell deletion of Nr4a1. Complete B-cell deletion of Nr4a1 led to increased atherosclerosis, which was accompanied by increased T follicular helper cell-germinal center axis response, as well as increased serum total cholesterol and triglycerides levels. Interestingly, specific MZB-cell deletion of Nr4a1 increased atherosclerosis in association with an increased T follicular helper-germinal center response but without any impact on serum cholesterol or triglyceride levels. Nr4a1-/- MZB cells showed decreased PDL1 (programmed death ligand-1) expression, which may have contributed to the enhanced T follicular helper response. Our findings reveal a previously unsuspected role for NR4A1 in the atheroprotective role of MZB cells.

Impact of sustained virological response on metabolic disorders in diabetic chronic hepatitis C virus patients after treatment with generic sofosbuvir and daclatasvir.

To evaluate the effect of generic sofosbuvir and daclatasvir (SOF/DCV) treatment on the glycemic state and insulin resistance as well as lipid profiles of those who achieved sustained virological response (SVR) in diabetic chronic hepatitis C virus (CHC) patients. We retrospectively reviewed 114 CHC patients with evidence of type 2 diabetes that were treated with generic SOF/DCV between May 2016 and August 2017. Baseline demographic and laboratory data were recorded. At 12-week post end of therapy (SVR12), glycemic state and insulin resistance as well as lipid profiles were re-evaluated and compared with baseline. A total of 98 diabetic CHC patients were finally included and were responders. A significant decline in the glycemic state as well as Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) values (P ≤ 0.0001) was observed, but HOMA-S showed a statistically significant increase (P ≤ 0.0001) at SVR12 in comparison to baseline values. Also, a significant increase in serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol levels was observed at SVR12 compared to baseline, but serum triglycerides levels showed a significant decrease. Logistic regression showed that the higher baseline HOMA-IR was a significant predictive variable of a decrease ≥20% of HOMA-IR, while higher baseline HOMA-IR and baseline triglycerides emerged as the only significant predictors of the Δ increase LDL-C level at SVR12. SOF/DCV-based therapy led to an improvement of glycemic state associated with a global worsening of lipid profile. Further studies are strongly warranted to evaluate the cardiovascular balance between amelioration of insulin resistance and negative changes of the lipid profile.

Maternal supplementation with uridine influences fatty acid and amino acid constituents of offspring in a sow-piglet model.

To investigate the cumulative effects of maternal supplementation with nucleotides in the form of uridine (UR) on fatty acid and amino acid constituents of neonatal piglets, fifty-two sows in late gestation were assigned randomly into the control (CON) group (fed a basal diet) or UR group (fed a basal diet with 150 g/t UR). Samples of neonates were collected during farrowing. Results showed that supplementing with UR in sows' diet significantly decreased the birth mortality of pigs (P = 0·05), and increased serum total cholesterol, HDL and LDL of neonatal piglets (P < 0·05). Moreover, the amino acid profile of serum and liver of neonatal piglets was affected by the addition of UR in sows' diets (P < 0·05). Furthermore, an up-regulation of mRNA expression of energy metabolism-related genes, including fatty acid elongase 5, fatty acid desaturase 1, hormone-sensitive lipase and cholesterol-7a-hydroxylase, was observed in the liver of neonates from the UR group. Additionally, a decrease in placental gene expression of excitatory amino acid transporters 2, excitatory amino acid transporter 3 and neutral AA transporter 1 in the UR group was concurrently observed (P < 0·05), and higher protein expression of phosphorylated protein kinase B, raptor, PPARα and PPARγ in placenta from the UR group was also observed (P < 0·05). Together, these results showed that maternal UR supplementation could regulate placental nutrient transport, largely in response to an alteration of mTORC1-PPAR signalling, thus regulating the nutrition metabolism of neonatal piglets and improving reproductive performance.

Lipid profile of regular kratom (Mitragyna speciosa Korth.) users in the community setting.

Background and aimKratom, or Mitragyna speciosa Korth., is a tropical plant that has been reported to exhibit opioid-like effects. Although opioids have been demonstrated to alter the lipid profile of regular users, data on the lipid-altering effects of kratom are scarce. This study aimed to compare the fasting lipid profile of regular kratom users to that of healthy subjects who do not use kratom. It also determined the association between various characteristics of kratom users and the serum triglycerides, total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels of regular kratom users.MethodsA total of 200 participants (n = 100 kratom users and n = 100 healthy subjects who do not use kratom) were recruited for this analytical cross-sectional study. Data on sociodemographic status, kratom use characteristics, cigarette smoking, physical activity, body mass index (BMI), fasting serum lipid profile, and liver function were collected from all participants.ResultsThe liver parameters of the study participants were within normal range. The serum total cholesterol and LDL of kratom users were significantly lower than those of healthy subjects who do not use kratom. There were no significant differences in the serum triglyceride and HDL levels. However, higher average daily frequency of kratom use and increasing age were associated with increased serum total cholesterol among kratom users. Other kratom use characteristics such as age of first kratom intake, duration of kratom use, and quantity of daily kratom intake were not associated with increased serum triglyceride, total cholesterol, LDL, and HDL levels.ConclusionsOur findings suggest regular kratom consumption was not linked to elevated serum lipids, except when there is a higher frequency of daily kratom intake. However, the study was limited by the small sample size, and hence a more comprehensive study with larger sample size is warranted to confirm the findings.

4013 Does dietary fat composition predict short-term elevations in lipid levels in adults on a modified Atkins diet?

OBJECTIVES/GOALS: The modified Atkins diet (MAD) is used in the management of drug-resistant epilepsy in adults. Some patients on MAD show an increase in serum levels of total cholesterol and low-density lipoprotein (LDL) cholesterol. We explored whether dietary fat composition predicts short-term elevations in serum lipid levels in diet-naïve adults who begin MAD. METHODS/STUDY POPULATION: Participants self-reported their diet intake with 3-day food records at baseline, 1 month and 2 months. Food records were analyzed using Nutrition Data System for Research software. Fasting serum levels of total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and triglycerides were also collected and LDL level calculated at baseline, 1 month, and 2 months. RESULTS/ANTICIPATED RESULTS: 38 patients submitted complete food records at each study visit (baseline, 1 month, and 2 month). Compared to baseline diet intake, there was a significant reduction in daily carbohydrate intake at 1 and 2 months months (p&lt;0.001). There was also a significant increase in daily saturated fatty acid (SFA) intake at 1 and 2 months (p&lt;0.001), daily mono-unsaturated fatty acid (MUFA) intake at 1 and 2 months (p&lt;0.001), and daily cholesterol intake at 1 month (p&lt;0.05) and 2 months (p&lt;0.001), but no change in daily poly-unsaturated fatty acid (PUFA) intake over time. Compared to baseline, there was a significant increase in serum LDL at 1 month (p&lt;0.001) and 2 months (p&lt;0.01) and an increase in serum TC at 1 month (p&lt;0.01) but not 2 months. DISCUSSION/SIGNIFICANCE OF IMPACT : Despite a significant increase in total fat, saturated fat and mono-unsaturated fat intake as well as an increase in total cholesterol and LDL levels following MAD initiation, dietary fat composition appears to minimally predict serum lipid values in the short term.

GC–MS-based metabolomics research on the anti-hyperlipidaemic activity of Prunella vulgaris L. polysaccharides

Prunella vulgaris polysaccharides (PVPs) have a variety of biological activities, but the mechanism and extent of their anti-hyperlipidaemic effect remain unclear. In vitro, PVPs had a significant inhibitory effect on angiotensin (Ang II)-induced vascular smooth muscle cell (VSMC) proliferation. A metabolomics approach based on gas chromatography–mass spectrometry (GC–MS) and chemometrics was established in this study to evaluate the anti-hyperlipidaemic activity of PVPs in a high-fat Sprague-Dawley rat model. In vivo, PVPs could significantly reduce the weight gain and the increases in serum total cholesterol (TC), low-density lipoprotein (LDL)-C and non-high-density lipoprotein (HDL)-C levels observed in rats fed a high-fat diet; they could also significantly increase serum GSH-Px activity, reduce the content of MDA and TNF-α and decrease abdominal fat volume in rats. Furthermore, PVPs exerted a repairing effect on morphological and structural damage in liver tissue cells in hyperlipidaemic rats fed a high-fat diet. PVPs improved lipid metabolism disorder in rats. Alanine, threonine, succinic acid, proline, inositol and arachidonic acid levels in the serum were considered potential biomarkers involved in amino acid, glucose, energy and lipid metabolism. Therefore, PVPs may interfere with hyperlipidaemia through anti-lipid peroxidation effects, attenuation of inflammation and regulation of glucose, amino acid, energy and lipid metabolism.

A study of lipid profile in subclinical hypothyroidism in tertiary care hospital, Kolkata, India

Background: Objective was to study lipid profile in patients of subclinical hypothyroidism in tertiary centre in Kolkata, West Bengal and compare the same with matched controls.Methods: This observational study (single exposure) was conducted May 2019 to Nov 2019 at Department of Medicine, KPC Medical College, Jadavpur, Kolkata in subjects diagnosed with Sub Clinical Hypothyroidism [defined as normal T3 or FT3, normal T4 or FT4, and with increased TSH. Sixty patients with subclinical hypothyroidism were selected after careful exclusion; lipid profile was compared with matched controls.Results: Between the two groups (group I - controls vs. group II - cases), the values were as follows: Mean serum total T3 value was 114.03±29.22 ng/dl vs. 106.15±36.24 ng/dl (p = 0.3476); mean total T4 was 7.07±1.69 μg/dl vs. 6.86±1.31 μg/dl (p = 0.535); mean TSH was 3.17±1.28 μIU/ml vs. 9.77±4.19 μIU/ml (p &lt;0.0001). Lipid profile pattern (group I vs. group II) was as follows: Mean total cholesterol (TC) 125.50±9.18 mg/dl vs. 162.07±42.32 mg/dl (p &lt;0.0001), mean triglycerides (TG) is 136.65±14.82 mg/dl vs. 148.90±65.27 mg/dl (p = 0.3236), low-density lipoprotein (LDL)-cholesterol is 62.17±7.40 mg/dl vs. 98.81±33.26 mg/dl (p &lt;0.0001), high-density lipoprotein (HDL)-cholesterol 39.17±6.62 mg/dl vs. 34.27±9.63 mg/dl (p = 0.0702), very low-density lipoprotein (VLDL) levels are 34.54±15.38 mg/dl vs. 32.08±13.21 mg/dl (p = 0.5245)..Conclusions: Subclinical hypothyroidism is associated with increased serum total cholesterol and LDL-Cholesterol levels. Therefore, there is a potential association between Subclinical hypothyroidism and atherosclerosis.
