Lipid Indices Research Articles

Yetiştiriciği Yapılan Üç Tür Alabalığın; Kaynak Alabalığı (Salvelinus fontinalis, Mitchill 1814), Gökkuşağı Alabalığı (Oncorhynchus mykiss Walbaum, 1972) ve Karadeniz Alasının (Salmo trutta labrax Pallas 1811) Biyokimyasal Özelliklerinin Farklılıkları

The objective of this present study is to signify biochemical features of three reared trouts (brook trout, rainbow trout, Black Sea trout) that are economically consequential and reared fish species in the Eastern Black Sea region. The rainbow trout has been reared successfully for a long period of time. However, brook trout and the Black Sea trout have been two new species to be reared in the region with a high potential contribution to the economy. Therefore, there is a strong need to determine and report the differences between the fish (especially the two new species), levels of carbohydrates, energy, carotenes (Vitamin A), fatty acid, and proximate composition (protein, lipid, moisture, and ash). In addition, the lipid indices [Atherogenic Index (AI), Thrombogenic Index (TI), and polyene index (PI)] were also measured and reported for the trouts. Moreover, the color of the fillets of the fish was also measured. The results of this present study show that the average levels of moisture and protein varied while the average levels of lipid and ash were close to each other. The highest levels of carbohydrates, energy, and carotenes were determined in the muscle of brook trout in this study. The highest meat yield was also obtained from brook trout followed by Black Sea trout and rainbow trout. A total of 19 fatty acids were determined for Black Sea trout and brook trout and 17 fatty acids for rainbow trout in the present study. The omega-3 levels of the all trout used for the present study were roughly twice as much as that of the omega-6, except for rainbow trout.

Improving the Use of White Lupine in the Laying Quail Feeding by Enzymes Addition: Effects on Productive Performances, Digestion, Blood Biochemical Indices and Eggs Quality

Lupine seeds are a valuable nutritive source for animal feeding, but for poultry nutrition, the content in crude fiber and non-starch polysaccharides (NSP) have an antinutritional factor. The aim of this research was to highlight the effect of partial soybean meal replacement with L. albus seeds and enzyme addition in the laying quail diets on productive performance, digestion, blood biochemical indices and egg quality. A total of 210 homogenous female Japanese quails (Coturnix japonica) at 24 week of age were randomly assigned to 6 dietary treatments, with the standard diet based on soybean meal unsupplemented (−) and supplemented with enzyme (+) (S−/S+) and the experimental diets on which the soybean meal was based partially substituted by including lupine in the amount of 200 g/kg and 250 g/kg, unsupplemented and supplemented with enzymes (L20−/L20+; L25−/L25+).The use of enzymes in the lupine-based diets allowed increasing the proportion of lupine in the diet of laying quails by up to 25% (% of feed) without changing egg production, egg weight, feed conversion rate and physical–chemical quality parameters of the eggs. In addition, the use of lupine (−/+) improved (p < 0.001) the carotenoid content of the egg yolk, as well as the quality of the yolk fats by decreasing the cholesterol content and the level of fatty acids (FA) with an atherogenic effect, in favor of omega-3 FA. Enzyme supplementation of the lupine-based diets had a negative effect on the health lipid indices of the fats in the yolk (ratio of the hypocholesterolemic/Hypercholesterolemic FA—h/H, atherogenic index—AI, thrombogenic index—TI and health promotion index—HPI). The use of exogenous enzymes increased the nutrients’ efficiency of the quails’ feed, which is supported by the improvement of the blood metabolic indices and a decrease of intestinal digesta viscosity and feces moisture. In conclusion, white lupine can be used up to 25% in the laying quail feed in association with specific enzymes without affecting the productive performance and egg quality; moreover, lupine use has improved the quality of the eggs, increasing humans’ health.

Effects of ambient particulate exposure on blood lipid levels in hypertension inpatients.

With modernization development, multiple studies of atmospheric particulate matter exposure conducted in China have confirmed adverse cardiovascular health effects. However, there are few studies on the effect of particulate matter on blood lipid levels in patients with cardiovascular disease, especially in southern China. The purpose of this study was to investigate the association between short- and long-term exposure to ambient particulate matter and the levels of blood lipid markers in hypertension inpatients in Ganzhou, China. Data on admission lipid index testing for hypertension inpatients which were divided into those with and without arteriosclerosis disease were extracted from the hospital's big data center from January 1, 2016 to December 31, 2020, and air pollution and meteorology data were acquired from the China urban air quality real time release platform from January 1, 2015 to December 31, 2020 and climatic data center from January 1, 2016 to December 31, 2020, with data integrated according to patient admission dates. A semi-parametric generalized additive model (GAM) was established to calculate the association between ambient particulate matter and blood lipid markers in hypertension inpatients with different exposure time in 1 year. Long-term exposure to particulate matter was associated with increased Lp(a) in three kinds of people, and with increased TC and decreased HDL-C in total hypertension and hypertension with arteriosclerosis. But particulate matter was associated with increased HDL-C for hypertension inpatients without arteriosclerosis, at the time of exposure in the present study. It is speculated that hypertension inpatients without arteriosclerosis has better statement than hypertension inpatients with arteriosclerosis on human lipid metabolism. Long-term exposure to ambient particulate matter is associated with adverse lipid profile changes in hypertension inpatients, especially those with arteriosclerosis. Ambient particulate matter may increase the risk of arteriosclerotic events in hypertensive patients.

Fatty Acid Indices and the Nutritional Properties of Karakul Sheep Meat.

This study aimed to evaluate the fatty acid profile and health lipid indices of sheep meat (from 52 Karakul sheep from NE Romania). The effect of age at slaughter and the influence of muscle region were studied for nutritional parameters, especially the fatty acids from lipid fractions. Based on the fatty acid profiles and lipid contents, the sanogenic indices were determined for two sheep muscle groups. Thus, two different muscle regions from lamb and adult sheep were analysed from both genders, the Longissimus dorsi and Triceps brachii, to argue the advantages of each category and the rationalization, in terms of meat consumption, regarding their impact on human health. Sheep meat has many components with beneficial effects on human health. Apart from the fact that it is an important source of nutrients due to its high content of proteins, lipids, and minerals, it is also a product that can provide fundamental bioactive compounds for maintaining metabolic functions. The qualitative indices assessment revealed that lambs have meat with high PUFA content on Longissimus dorsi muscles (approx. 25% of total fatty acids), 0.68 for PUFA/SFA, with highest values for n-3 (approx. 8%) and n-6 (approx. 14%). Appropriate values can also be observed in Triceps brachii muscles from adult sheep. The sanogenic indices also presented good values for Longissimus dorsi from lambs and Triceps brachii from adult sheep (polyunsaturation index = 7.2-10.2; atherogenic index = 0.56-0.67; thrombogenic index = 0.78-0.96; hypocholesterolemic/hypercholesterolemic index = 2.4-2.7 (for Longissimus dorsi)).

Effectiveness of Wearable Activity Monitors on Metabolic Outcomes in Patients With Type 2 Diabetes: A Systematic Review and Meta-Analysis

ObjectiveWearable activity monitors are promising tools for improving metabolic outcomes in patients with type 2 diabetes mellitus (T2DM); however, no uniform conclusive evidence is available. This study aimed to evaluate the effects of the intervention using wearable activity monitors on blood glucose, blood pressure, blood lipid, weight, waist circumference, and body mass index (BMI) in individuals with T2DM. MethodsTwo independent reviewers searched 4 online databases (PubMed, Cochrane Library, Web of Science, and Embase) to identify relevant studies published from January 2000 to October 2022. The primary outcome indicator was hemoglobin A1c (HbA1c), and the secondary outcome indicators included physical activity (steps per day), fasting blood glucose, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol, systolic blood pressure, diastolic blood pressure, BMI, waist circumference, and weight. ResultsA total of 25 studies were included. The HbA1c level (standardized mean difference [SMD], −0.14; 95% confidence interval [CI], −0.27 to −0.02; P = .02; I2 = 48%), BMI (SMD, −0.16; 95% CI, −0.26 to −0.05; P = .002; I2 = 0), waist circumference (SMD, −0.21; 95% CI, −0.34 to −0.09; P < .001; I2 = 0), and steps/day (SMD, 0.55; 95% CI, 0.36-0.94; P < .001; I2 = 77%) significantly improved. ConclusionWearable activity monitor–based interventions could facilitate the improvement of the HbA1c level, BMI, and waist circumference and increase in physical activity in individuals with T2DM. Wearable technology appeared to be an effective tool for the self-management of T2DM; however, there is insufficient evidence about its long-term effect.

Adiposity impacts cognitive function in Asian populations: an epidemiological and Mendelian Randomization study

Obesity and related metabolic disturbances including diabetes, hypertension and hyperlipidemia predict future cognitive decline. Asia has a high prevalence of both obesity and metabolic disease, potentially amplifying thefuture burden of dementia in the region. We aimed to investigate the impact of adiposity and metabolic risk oncognitive function in Asian populations, using an epidemiological analysis and a two-sample Mendelian Randomization (MR) study. The Health for Life in Singapore (HELIOS) Study is a population-based cohort of South-East-Asian men and women in Singapore, aged 30-84 years. We analyzed 8769 participants with metabolic and cognitive data collected between 2018 and 2021. Whole-body fat mass was quantified with Dual X-Ray Absorptiometry (DEXA). Cognition was assessed using a computerized cognitive battery. An index of general cognition ' g ' was derived through factor analysis. We tested the relationship of fat mass indices and metabolic measures with ' g ' using regression approaches. We then performed inverse-variance-weighted MR of adiposity and metabolic risk factors on ' g ', using summary statistics for genome-wide association studies of BMI, visceral adipose tissue (VAT), waist-hip-ratio (WHR), blood pressure, HDL cholesterol, triglycerides, fasting glucose, HbA1c, and general cognition. Participants were 58.9% female, and aged 51.4 (11.3) years. In univariate analysis, all 29 adiposity and metabolic measures assessed were associated with ' g ' at P<0.05. In multivariable analyses, reduced ' g ' was consistently associated with increased visceral fat mass index and lower HDL cholesterol (P<0.001), but not with blood pressure, triglycerides, or glycemic indices. The reduction in ' g ' associated with 1SD higher visceral fat, or 1SD lower HDL cholesterol, was equivalent to a 0.7 and 0.9-year increase in chronological age respectively (P<0.001). Inverse variance MR analyses showed that reduced ' g ' is associated with genetically determined elevation of VAT, BMI and WHR (all P<0.001). In contrast, MR did not support a causal role for blood pressure, lipid, or glycemic indices on cognition. We show an independent relationship between adiposity and cognition in a multi-ethnic Asian population. MR analyses suggest that both visceral adiposity and raised BMI are likely to be causally linked to cognition. Our findings have important implications for preservation of cognitive health, including further motivation for action to reverse the rising burden of obesity in the Asia-Pacific region.

Metabolome-wide association study of four groups of persistent organic pollutants and abnormal blood lipids

Environmental exposure increases the risk of dyslipidemia, which affects human health. Research has shown that persistent organic pollutants (POPs), including per- and polyfluoroalkyl substances (PFASs), polychlorinated biphenyls, polybrominated diphenyl ethers, and phthalate metabolites, are associated with a higher risk of abnormal blood lipid levels in humans. However, the key molecules involved in dyslipidemia and the mechanisms are not fully understood. This study aims to investigate the biomarkers that mediate the relationships between blood lipids and four groups of POPs and revealed their potential mechanisms. Specifically, in 278 male blood samples, blood lipid and POPs levels were measured and metabolites were detected using untargeted metabolomics. Spearman’s correlation analysis and binary logistic regression were employed to assess the relationship between POPs and lipid indexes. We observed that PFASs were associated with a higher risk of abnormal total cholesterol (TC) and low-density lipoprotein (LDL), while other POPs displayed little association with abnormal lipid indexes. Among all the PFASs, 6:2Cl-PFESA was associated with the fewest metabolites. A metabolome-wide association study combined with a meet-in-the-middle approach was used to identify potential biomarkers that mediate the association between POPs and abnormal blood lipids. The mediation analysis pointed to 105 significant mediators as potential biomarkers mediating the association between PFASs and TC, and 82 significant mediators were potential biomarkers that mediated the association between PFASs and LDL. 24-Hydroxycholesterol, 3alpha,7alpha-dihydroxy-5beta-cholestan-26-al, PC(18:0/0:0), PC(22:5/0:0), GPCho(18:1/18:1), LysoPC(22:2(13Z,16Z)), LysoPC(16:0), 9(S)-HODE, 9,10-DHOME, l-glutamate, 4-hydroxybutyric acid, cytosine, PC(14:1(9Z)/18:0), sphinganine, and (S)-beta-aminoisobutyrate were identified as important biomarkers. The mechanism may mainly involves glycerophospholipid metabolism, primary bile acid biosynthesis, and linoleic acid metabolism. PPARγ likely plays a role in the associations between PFASs and abnormal cholesterol metabolism. Overall, our study provides clues for the early detection of PFAS-induced dyslipidemia and brings forth a theoretical framework for further research into this mechanism.

Associations of novel serum lipid index with epithelial ovarian cancer chemoresistance and prognosis.

To evaluate the relationship between novel serum lipid index and chemoresistance as well as prognosis of epithelial ovarian cancer (EOC). Patients' serum lipid profiles of 249 cases diagnosed with epithelial ovarian cancer, including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) as well as their ratios, the novel indicators HDL-C/TC and HDL-C/LDL-C, and clinicopathologic characteristics were retrospectively collected and calculated from January 2016 to January 2020 and correlation between serum lipid index and clinicopathological features such as chemoresistance as well as prognosis were evaluated. 249 patients pathologically diagnosed EOC who underwent cytoreductive surgery were included in our cohort. The mean age of these patients was 55.20 ± 11.07 years. Binary logistic regression analyses indicated Federation International of Gynecology and Obstetrics (FIGO(stage and HDL-C/TC ratio had significant association with chemoresistance. Univariate analyses demonstrated pathological type, chemoresistance, FIGO stage, neoadjuvant chemotherapy, maintenance treatment, HDL-C/LDL-C ratio, HDL-C/TC ratio were related to Progression-Free Survival (PFS) and Overall Survival (OS) (P<0. 05). Particularly, multivariate analyses indicated that HDL-C/LDL-C ratio was independent protective factors for both PFS and OS. The complex serum lipid index HDL-C/TC ratio has a significant correlation with chemoresistance. HDL-C/LDL-C ratio is closely related to the clinicopathological characteristics and prognosis of patients with EOC and is an independent protective factor indicating better outcome.

Antihyperlipidemic potential of dietary supplementation with carnosine in high-fat diet-fed rats.

The aim of this study was to investigate the hypolipidemic effects of carnosine and a commercial carnosine supplement on lipid status, liver and kidney function, and inflammation associated with dyslipidemia in rats with high-fat diet-induced hyperlipidemia. The study was conducted on adult male Wistar rats, divided into control and experimental groups. Animals were kept in standard laboratory conditions and according to groups were treated with saline, carnosine, carnosine dietary supplement, simvastatin, and their combinations. All substances were prepared fresh every day and used by oral gavage. Treatment with a carnosine-based supplement significantly improved total and LDL cholesterol levels in serum, especially in the combination with simvastatin as a conventional drug in dyslipidemia treatment. The effect of carnosine on the metabolism of triglycerides was not as evident as in the case of cholesterol. Nevertheless, the values of the atherogenic index showed that the combinations of carnosine and carnosine supplement with simvastatin were the most effective in lowering this comprehensive lipid index. Dietary carnosine supplementation resulted also in anti-inflammatory effects, as demonstrated by immunohistochemical analyses. Besides, the good safety profile of carnosine in terms of its effect on liver and kidney functions was also confirmed. The use of carnosine supplements in preventing and/or treatment of metabolic disorders requires further investigations into the mechanisms of action and potential interactions with conventional therapy.

Hydroxysafflor yellow A regulates lymphangiogenesis and inflammation via the inhibition of PI3K on regulating AKT/mTOR and NF-κB pathway in macrophages to reduce atherosclerosis in ApoE-/- mice

BackgroundMacrophage-mediated inflammatory infiltration and pathological lymphangiogenesis around atherosclerotic plaques are newly highlighted treatment targets of atherosclerosis. Although the effect of Hydroxysafflor yellow A(HSYA) on atherosclerosis was clear, few studies focus on the regulation of HSYA on such mechanisms. PurposeThis study aimed to uncover the key site of HSYA on improving atherosclerosis by regulating macrophage-induced inflammation and lymphangiogenesis. Study designThis study was designed to explore the new mechanism of HSYA on alleviating atherosclerosis in vitro and in vivo. MethodsWe determined the expression of vascular endothelial growth factor C(VEGF-C) in Raw264.7 cells and high-fat diet fed ApoE knockout (ApoE−/−) mice. Raw264.7 cells were treated with HSYA under the stimulation of LPS and ox-LDL. HFD induced ApoE−/− mice were given different concentrations of HSYA-saline solution by tail vein injection and ATV-saline suspension by gavage. C57/B6j mice fed with chow diet were used for the control group. H&E, oil red O and immunofluorescence staining analysis were used for visualizing the pathological changes. The biological impact of HSYA was evaluated by body weight, lipid metabolism, inflammation levels, and corresponding function indexes of kidney and liver. RT-qPCR and western blot methods were conducted to determine the expression of the inflammation and lymphangiogenesis factors. Molecular docking and microscale thermophoresis analysis were used to verify the combination of HSYA and PI3K. ResultsIn vivo, HSYA reduced the plaque formation, hepatic steatosis and inflammation-related lymphangiogenesis (IAL). It also changed the serum levels of inflammation (VEGF-C, TNF-α, IL-6, VCAM1, MCP1), lipid indexes (LDL, CHOL, TRIG) and relevant lymphangiogenesis (VEGF-C and LYVE-1) and inflammation (VCAM-1 and IL-6) signals in the aorta. In vitro, HSYA regulated Akt/mTOR and NF-κB activation by the inhibition of PI3K in macrophages. ConclusionHSYA affects inflammation and inflammation-associated lymphangiogenesis via suppressing PI3K to affect AKT/mTOR and NF-B pathway activation in macrophages, showing a comprehensive protective effect on atherosclerosis.

Effects of feeding methods on growth and slaughter performance, blood biochemical indices, and intestinal morphology in Minxinan black rabbits (Oryctolagus cuniculus)

Feed restriction after weaning is a common strategy used in commercial rabbit farms to improve feed efficiency, promote health, and reduce mortality. However, few studies have investigated the feed restrictions of Minxinan black rabbits (Oryctolagus cuniculus). Thus, the effects of feed restriction on growth and slaughter performance, intestinal morphology, and blood biochemical indices of Minxinan black rabbits were evaluated in this study. Rabbits in group A (control group) had ad libitum intake, while those in feed restriction groups (groups B, C, and D) were restricted to 80% of the average daily feed intake (ADFI) of group A the day before. The rabbits in group B were fed once per day at 8:00 am. Rabbits in groups C and D were fed twice per day at 8:00 am (50%) and 4:00 pm (50%) and 8:00 am (30%) and 4:00 pm (70%), respectively. The experimental period lasted for 8 weeks. Compared to that in group A, the diarrhea rate of group C was significantly decreased (P < 0.05), and the ADFI, feed conversion ratio, abdominal fat weight, abdominal fat rate, total protein, albumin, globulin, alanine aminotransferase (ALT), low-density lipoprotein, and intestinal crypt depth of all feed restriction groups were significantly reduced (P < 0.01). Feed conversion ratio in group D was significantly better than that in groups B and C (P < 0.05). The efficiency index (EI) of groups C and D was higher than that of groups A and B (P < 0.01). Triglyceride levels in groups C and D were significantly lower than those in group A. The villus length to crypt depth of the duodenum and jejunum in group D was significantly higher than that in group A (P < 0.01). In conclusion, the following parameters can be improved by feed restriction: feed conversion ratio, diarrhea rate, abdominal fat rate, serum ALT, lipid indices and intestinal health of Minxinan black rabbits, and the EI of the farm. Feeding twice per day, 30% at 8:00 am and 70% at 4:00 pm, had the best comprehensive effects.

Correlation between serum cystatin C and lipid level in patients with chronic heart failure.

Serum cystatin C (Cys C) and blood lipid levels are related to the occurrence and development of chronic heart failure (CHF). However, there are few reports on the correlation between blood lipid level and serum Cys C level in patients with CHF. The aim of this study is to explore the correlation between serum Cys C level and blood lipid level in patients with CHF, and to provide valuable reference for clinical diagnosis and treatment of CHF. A total of 336 CHF patients who were hospitalized in the Department of Cardiovascular Medicine of Shaanxi Provincial People's Hospital from October 2017 to July 2018 were included and they were divided into a Cys C normal group (n=180) and a Cys C abnormal group (n=156) according to serum Cys C level of the patients. The general data, laboratory indicators, and cardiac ultrasound results were compared between the 2 groups. Pearson correlation analysis was used to detect the correlation between serum Cys C level and blood lipid level and other factors, and the data related to Cys C were further analyzed by multivariate logistic regression. Compared with the Cys C normal group, patients in the Cys C abnormal group had lower left ventricular ejection fraction (LVEF) (P<0.001), older age (P=0.030), higher incidence rate of diabetes and smoking index (P=0.002 and P=0.003, respectively). The levels of serum creatinine (SCr), blood urea nitrogen (BUN), and total bilirubin (TBIL) were higher (all P<0.001), while the levels of high density lipoprotein (HDL), apolipoprotein (Apo) A, and albumin (ALB) were lower (P<0.001, P=0.001, and P=0.003, respectively) in the Cys C abnormal group. Pearson correlation analysis showed that serum Cys C level was negatively correlated with platelet count, HDL, Apo A, ALB, and LVEF. It was positively correlated with smoking index, mean platelet volume, neutrophil ratio, BUN, and TBIL (all P<0.05). The results of multivariate logistic regression analysis showed that the decreased HDL level was a risk factor for the abnormality of serum Cys C in patients with CHF (OR=0.119, P=0.003), while Apo A was not a risk factor for its abnormality (P=0.337). HDL might be the only blood lipid index associated with abnormal serum Cys C in patients with CHF.

Association of mineral status with metabolic disorders in newly diagnosed hypertensive patients. A preliminary study

Background: Hypertension and comorbid diseases are often characterized by inadequate intake of minerals and disturbances in mineral status. Aim: This study aimed to estimate the association of minerals status and dietary supply of minerals with body mass index (BMI) and serum levels of glucose and lipids in newly diagnosed hypertensive patients. Methods: A total of 69 hypertensive patients were included in the study. Blood pressure and BMI were recorded, and the levels of total cholesterol (TC), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides (TG), and glucose were measured in the serum of all subjects. Furthermore, the concentrations of iron, zinc, and copper were measured in serum, erythrocyte, urine, and hair samples. The dietary intake of energy and minerals was also estimated. The association between minerals and metabolic parameters was analyzed using Spearman's rank correlation and multivariate regression. Results: The results showed a significant negative correlation of the iron level in serum and copper level in erythrocytes with BMI was found. The zinc concentration in serum positively correlated with the level of TG. Multivariate regression analysis in the crude model and the model adjusted for age and gender showed the relationship between the iron level in urine and TC and also between the iron level in serum and BMI. Conclusion: The levels of iron, copper, and zinc were associated with metabolic parameters such as BMI and levels of lipids and glucose in newly diagnosed hypertensive patients.

White and honey Chlorella vulgaris: Sustainable ingredients with the potential to improve nutritional value of pork frankfurters without compromising quality

This study aimed to evaluate the effect of the chlorophyll-deficient microalgae mutants, honey (yellow) and white Chlorella vulgaris, (3%) on the nutritional, physicochemical, microbiological, and sensory characteristics of frankfurters. The presence of microalgae resulted in increased PUFA content and higher PUFA/SFA ratio, but lower n-6/n-3 ratio and lipid indices (P < 0.05). C. vulgaris inclusion in frankfurters increased (P < 0.05) Na, K, Ca, P, and Zn and improved the Na/K ratio, but lowered Mn, and in the case of white C. vulgaris, Cu content, compared to the control. The higher protein content decreased water release from emulsions elaborated with microalgae. White C. vulgaris inclusion decreased cohesiveness and springiness of the frankfurters. Due to the presence of pigment, microalgae inclusion led to a decrease in redness and an increase in yellowness of frankfurters. The presence of microalgae resulted in lower (P < 0.05) bacterial counts and did not affect TBARs during storage. The addition of microalgae in frankfurters produced acceptable sensory characteristics but resulted in lower scores compared to reference products.

Growth Performance, Meat Quality, Welfare and Behavior Indicators of Broilers Fed Diets Supplemented with Yarrowia lipolytica Yeast

This study investigated the dietary impact of dried Yarrowia lipolytica yeast (YLP) on the growth performance, meat quality, welfare and behavior indicators of broilers. It was performed in a commercial poultry farm using 108 13 day-old Ross 308 male broilers. The chicks were randomly and equally divided into three dietary groups CON, YLP3 and YLP5, according to the incorporation rate of YLP in the feed (0%, 3%, and 5%, respectively). A positive effect on foot pad dermatitis (FPD) of YLP-fed broilers was observed without any adverse effects on welfare, behavior, meat quality and the overall growth performance of the broilers. YLP significantly decreased the malondialdehyde (MDA) values in breast and thigh meat. YLP3 birds presented a superior nutrient quality of breast meat, as indicated by the increased concentration of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs), decreased levels of saturated fatty acids (SFAs), a better PUFA/SFA ratio and improved health lipid indices. A significant elevation of n-3 PUFAs was observed in the thigh meat of YLP-fed groups, compared to the CON groups. A positive effect on the overall sensory acceptance of thigh meat was detected in the YLP5 group. YLP feeding, at the rate of 3%, seems to be beneficial for improving the meat nutrition quality.

Glipizide has Low Influences on Lipid Index and Major Organs Weight Variation and Considerable Anxiolytic Properties: An in vivo Investigation

Association between atherogenic index of plasma and in-hospital mortality in patients with STEMI undergoing primary percutaneous coronary intervention

Aim: Dyslipidemia is an established risk factor for cardiovascular disease. Increased triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) levels, and decreased high lipoprotein cholesterol (HDL-C) levels were associated with increased cardiovascular risk. Recently, comprehensive lipid profile indices derived from these conventional parameters have attracted to attention. Atherogenic index of plasma (AIP) is one of the indices calculated as the logarithm of TG/HDL-C levels and it is accepted as an alternative and simple marker of plasma atherogenicity. Although various studies demonstrated that their relationship with these lipid indices and clinical outcomes in patients with acute coronary syndrome, this situation is not yet clear in acute ST-elevation myocardial infarction (STEMI) patients undergoing primer percutaneous coronary intervention (pPCI). In this study, we aimed to investigate the relationship of AIP with early mortality in STEMI patients undergoing pPCI.Material and Method: This is a retrospective, single center, hospital-based study carried out between January 2019 and April 2021. A total of 873 consecutive STEMI patients (705 men; median age 59 years), whose undergoing pPCI, were enrolled. The patients were divided into two groups according to in-hospital mortality status namely survivors vs non-survivors. Conventional lipid values were measured and non-traditional lipid indexes including non-HDL-C [Total cholesterol minus HDL-C], Total cholesterol/HDL-C, LDL-C/HDL-C, atherogenic index (AI) [non-HDL-C/HDL-C], lipoprotein combine index (LCI) [Total cholesterol*TG*LDL-C/HDL-C] and atherogenic index of plasma (AIP) [Log(TG/HDL-C)] were calculated. Angiographic images of the patients were evaluated through the hospital automation system. Results: AIP was significantly higher in non-survivors compared to survivor group (0.59, 0.47, p=0.006, respectively). AI, non-HDL-C, Total cholesterol/HDL-C ratio, LDL-C/HDL-C ratio and LCI measurements were similar between two groups. The cut-off value of the AIP (0.50) was associated with 70% sensitivity and 52% specificity for predicts in-hospital mortality. Multivariate logistic regression model indicated AIP (OR: 3.77, 95% CI: 1.34–10.6, p &amp;lt; 0.012) as independent predictor of in-hospital mortality in STEMI patients undergoing pPCI. Conclusion: AIP predicts in-hospital mortality in patients with STEMI undergoing pPCI. AIP, which can be calculated easily by complete blood can be beneficial in evaluating the prognosis of these patients.

Predictive effect of different blood lipid parameters combined with carotid intima-media thickness on coronary artery disease.

Blood lipids disorder and atherosclerosis are closely related to coronary artery disease (CAD). This study aims to compare different blood lipid parameters combined with carotid intima-media thickness (cIMT) in predicting CAD. This was a retrospective study including patients who underwent coronary angiography for highly suspected CAD. Blood samples were taken for lipid profile analysis and cIMT was evaluated by carotid ultrasound. Logistic analysis was used to establish different models of different lipid parameters in predicting CAD. The area under the receiver operating characteristic curve (AUC) was used to examine the predictive value. The optimal lipid parameter was also used to explore the relationship with multi-vessel CAD. Patients were classified into two groups based on whether CAD existed. Compared with non-CAD patients, the CAD group had higher lipoprotein (a) [Lp (a)], apolipoprotein B/apolipoprotein A, total cholesterol/high-density lipoprotein cholesterol (HDL-C), triglyceride/HDL-C and LDL-C/HDL-C. According to the AUCs, Lp (a) combined with cIMT (AUC: 0.713, P < 0.001) had the best performance in predicting CAD compared to other lipid parameters. High level of Lp (a) was also associated with multi-vessel CAD (odds ratio: 1.41, 95% confidence interval: 1.02-1.95, P = 0.036). For patients with highly suspected CAD, Lp (a) better improved the predictive value of CAD rather than most of blood lipid indices, especially in the absence of high levels of LDL-C. Lp (a) also can be used to predict the multi-vessel CAD.

Effects of Zhishi Daozhi Decoction on the intestinal flora of nonalcoholic fatty liver disease mice induced by a high-fat diet.

Nonalcoholic fatty liver disease (NAFLD) is the most common type of chronic liver disease with a high incidence, and the situation is not optimistic. Intestinal flora imbalance is strongly correlated with NAFLD pathogenesis. Zhishi Daozhi Decoction (ZDD) is a water decoction of the herbs used in the classical Chinese medicine prescription Zhishi Daozhi Pills. Zhishi Daozhi Pills has shown promising hepatoprotective and hypolipidemic properties, but its specific mechanism remains unclear. Mice were fed on a high fat-rich diet (HFD) for ten weeks, and then the animals were administrated ZDD through oral gavage for four weeks. The serum liver function and blood lipid indexes of the mice were then tested using an automatic biochemical analyzer. H&E and Oil Red O staining were used to observe the pathological conditions of mice liver tissue, and 16S rRNA sequencing technology was used to analyze the changes in intestinal flora of mice. The concentration of short-chain fatty acids (SCFAs) in the gut of mice was analyzed by gas chromatography-mass spectrometry (GC-MS). The expression of tight junction (TJ) proteins between ileal mucosal epithelial cells was analyzed using the immunofluorescence technique. ZDD was found to reduce the bodyweight of NAFLD mice, reduce serum TG, CHO, ALT, and AST levels, reduce fat accumulation in liver tissue, make the structure of intestinal flora comparable to the control group, and increase the concentration of intestinal SCFAs. It was also found to increase the expression of TJ proteins such as occludin and ZO-1, making them comparable to the control group. ZDD has a therapeutic effect on NAFLD mice induced by HFD, which may act by optimizing the intestinal flora structure.

Effect of evolocumab on the progression of intraplaque neovascularization of the carotid based on contrast-enhanced ultrasonography (EPIC study): A prospective single-arm, open-label study.

Background and Purpose: The aim of this study was to explore the effect of half a year of evolocumab plus moderate-intensity statin treatment on carotid intraplaque neovascularization (IPN) and blood lipid levels. Methods: A total of 31 patients with 33 carotid plaques who received evolocumab plus statin treatment were included. Blood lipid levels, B-mode ultrasound and contrast-enhanced ultrasonography (CEUS) at baseline and after half a year of evolocumab plus statin therapy were collected. The area under the curve (AUC) reflected the total amount of acoustic developer entering the plaque or lumen within the 180s measurement period. The enhanced intensity reflected the peak blood flow intensity during the monitoring period, and the contrast agent area reflected the area of vessels in the plaques. Results: Except for high-density lipoprotein cholesterol (HDL-c), all other lipid indices decreased. Compared with baseline, low-density lipoprotein cholesterol (LDL-c) decreased by approximately 57% (p < 0.001); total cholesterol (TC) decreased by approximately 34% (p < 0.001); small dense low-density lipoprotein (sd-LDL) decreased by approximately 52% (p < 0.001); and HDL-c increased by approximately 20% (p < 0.001). B-mode ultrasonography showed that the length and thickness of the plaque and the hypoechoic area ratio were reduced (p < 0.05). The plaque area, calcified area ratio, and lumen cross-sectional area changed little (p > 0.05). CEUS revealed that the area under the curve of plaque/lumen [AUC (P/L)] decreased from 0.27 ± 0.13 to 0.19 ± 0.11 (p < 0.001). The enhanced intensity ratio of plaque/lumen [intensity ratio (P/L)] decreased from 0.37 ± 0.16 to 0.31 ± 0.14 (p = 0.009). The contrast agent area in plaque/area of plaque decreased from 19.20 ± 13.23 to 12.66 ± 9.59 (p = 0.003). The neovascularization score decreased from 2.64 ± 0.54 to 2.06 ± 0.86 (p < 0.001). Subgroup analysis based on statin duration (<6months and ≥6months) showed that there was no significant difference in the AUC (P/L) or intensity ratio (P/L) at baseline or after half a year of evolocumab treatment. Conclusion: This study found that evolocumab combined with moderate-intensity statins significantly improved the blood lipid profile and reduced carotid IPN.
