The effects of kettlebell training versus resistance training using the own body mass on physical fitness and physiological adaptations in obese adults: a randomized controlled trial

Aim of studyThis study aimed to explore the effects of different types of resistance training using kettlebells versus the own body mass, in comparison to a passive control, on key physical fitness and physiological parameters in young, obese adults.MethodsData from 60 sedentary, obese male college students, aged 17–26, were used for final analyses. Participants were randomly assigned to one of three groups: a control group (CG, n = 20, no training), a kettlebell resistance training group (KRTG, n = 20), or a bodyweight resistance training group (BWRTG, n = 20). Selected measures of physical fitness were tested using the 12-minutes run test, the push-up test, the sit-up test, and the sit-and-reach test. Physiological measures included vital capacity, resting and maximum heart rate (HRmax), mean arterial blood pressure, breath holding time, and respiratory rate. Biochemical variables were measured in the morning, in a fasted state, and comprised high and low density lipoprotein, total cholesterol, and triglycerides. The 12-weeks progressive KRTG and BWRTG were specifically tailored using sets, repetitions, and intensity levels.ResultsNotable findings include significant body fat reductions in BWRTG (p < 0.001; d = 1.53) and KRTG (p < 0.001; d = 1.43), and a substantial increase in VO2max for BWRTG (p < 0.001; d = 1.32) and KRTG (p < 0.001; d = 1.34) compared to CG. KRTG also showed significant improvements in vital capacity (p < 0.001; d = 1.61) and reductions in resting heart rate (p = 0.024, d = 1.05) and respiratory rate (p = 0.001, d = 1.55), with BWRTG showing similar trends (resting heart rate: p = 0.041, d = 1.35; respiratory rate: p = 0.001, d = 1.98). Both intervention groups significantly improved breath holding time (KRTG: p = 0.001, d = 1.58; BWRTG: p < 0.001, d = 1.98) and reduced total cholesterol and low-density lipoprotein levels compared to CG.ConclusionsThis study demonstrates that both KRTG and BWRTG are effective in improving body composition and selected fitness and physiological measures. Thus, resistance training using kettlebells or bodyweight training are recommended if the goal is to improve body composition and fitness in obese male adults.Trial RegistrationOSF, September, 28th 2023. https://doi.org/10.17605/OSF.IO/Z6Y9Gosf.io/2mb98

Serum Levels of Adiponectin Are Strongly Associated with Lipoprotein Subclasses in Healthy Volunteers but Not in Patients with Metabolic Syndrome.

Metabolic syndrome (MS) is a widespread disease in developed countries, accompanied, among others, by decreased adiponectin serum levels and perturbed lipoprotein metabolism. The associations between the serum levels of adiponectin and lipoproteins have been extensively studied in the past under healthy conditions, yet it remains unexplored whether the observed associations also exist in patients with MS. Therefore, in the present study, we analyzed the serum levels of lipoprotein subclasses using nuclear magnetic resonance spectroscopy and examined their associations with the serum levels of adiponectin in patients with MS in comparison with healthy volunteers (HVs). In the HVs, the serum levels of adiponectin were significantly negatively correlated with the serum levels of large buoyant-, very-low-density lipoprotein, and intermediate-density lipoprotein, as well as small dense low-density lipoprotein (LDL) and significantly positively correlated with large buoyant high-density lipoprotein (HDL). In patients with MS, however, adiponectin was only significantly correlated with the serum levels of phospholipids in total HDL and large buoyant LDL. As revealed through logistic regression and orthogonal partial least-squares discriminant analyses, high adiponectin serum levels were associated with low levels of small dense LDL and high levels of large buoyant HDL in the HVs as well as high levels of large buoyant LDL and total HDL in patients with MS. We conclude that the presence of MS weakens or abolishes the strong associations between adiponectin and the lipoprotein parameters observed in HVs and disturbs the complex interplay between adiponectin and lipoprotein metabolism.

GROWTH PERFORMANCE AND LIPID PROFILE OF ARCHACHATINA MARGINATA (GIANT AFRICAN LAND SNAIL) FED VARYING LEVELS OF RIPE EGGPLANT FRUITS BASED DIETS

The performance of African giant land snails (Archachatina marginata) fed ripe eggplant fruits was studied using eighty-four (84) juvenile (four months old) Archachatina marginata for eight (8) weeks. The study evaluated the snails' growth performance and lipid profile (total cholesterol, low-density lipoprotein, high-density lipoprotein and triglycerides). The snails were divided into four treatment groups, with twenty-one (21) snails per group in a completely randomized design (CRD). Treatments 1, 2, 3 and 4 had varying levels of ripe eggplant fruits at 0%, 5%, 10% and 15% inclusion levels respectively. Isocaloric and isonitrogenous feeds and water were provided ad libitum, while other management practices were strictly adhered to. The results showed no significant differences (P&gt;0.05) in growth performance across treatments. The results also revealed that total cholesterol decreased (P&lt;0.05) significantly as the levels of ripe eggplant fruits increased across treatments. There were no significant differences (P&gt;0.05) in low-density lipoprotein and triglycerides, while high-density lipoprotein differed (P&lt;0.05) significantly across treatments. The result also showed a linear increase in high-density lipoprotein ("good" cholesterol) as the levels of ripe eggplant fruits increased across treatments. Therefore, a 15% inclusion level of ripe eggplant fruits in the diet of Archachatina marginata reduces total cholesterol levels and increases high-density lipoprotein without any adverse effect on growth. The study recommends using ripe eggplant fruits to formulate diets for animals with high cholesterol content and high levels of low-density lipoprotein in their meat.

Nutritional Strategies to Mitigate Complications and Improve Long-Term Functionality of Autologous Arteriovenous Fistula Post Ultrasound and DSA Guided Balloon Dilation

This prospective cohort study evaluated the efficacy of omega-3 fatty acid supplementation on arteriovenous fistula patency and systemic inflammation in 220 hemodialysis patients undergoing ultrasound and digital subtraction angiography-guided balloon dilation. The participants were randomized into an intervention group receiving 2,000 mg of omega-3 fatty acids daily and a placebo group. The primary outcome measures were arteriovenous fistula patency at 12- and 24-months post-dilation, while secondary outcomes included thrombosis incidence, changes in inflammatory markers (c-reactive protein and interleukin-6), lipid profiles, and health-related quality of life (HRQoL). Results indicated a significant improvement in arteriovenous fistula patency in the omega-3 group at 24 months (80.9 vs. 68.2%, P &lt; 0.05). Additionally, there was a significant reduction in thrombosis rates (7.3 vs. 16.4%, P &lt; 0.05) and inflammatory markers (c-reactive protein and interleukin-6) in the omega-3 group compared to the placebo. Lipid profile analysis showed a decrease in total cholesterol and low-density lipoprotein levels with omega-3 supplementation, with significant changes at 12 months (P &lt; 0.05). HRQoL scores also improved significantly in the omega-3 group at both 12 and 24 months (P &lt; 0.05). These findings suggest that omega-3 fatty acids can enhance arteriovenous fistula functionality and reduce cardiovascular risk factors in hemodialysis patients. And its integration into standard care protocols for patients with arteriovenous fistulas would improve long-term outcomes.

It is Time to Screen for Homozygous Familial Hypercholesterolemia in the United States.

Homozygous familial hypercholesterolemia (HoFH) is an ultra-rare inherited condition that affects approximately one in 300,000 people. The disorder is characterized by extremely high, life-threatening levels of low-density lipoprotein (LDL) cholesterol from birth, leading to significant premature cardiovascular morbidity and mortality, if left untreated. Homozygous familial hypercholesterolemia is severely underdiagnosed and undertreated in the United States (US), despite guidelines recommendations for universal pediatric lipid screening in children aged 9-11. Early diagnosis and adequate treatment are critical in averting premature cardiovascular disease in individuals affected by HoFH. Yet, an unacceptably high number of people living with HoFH remain undiagnosed, misdiagnosed, and/or receive a late diagnosis, often after a major cardiovascular event. The emergence of novel lipid-lowering therapies, along with the realization that diagnosis is too often delayed, have highlighted an urgency to implement policies that ensure timely detection of HoFH in the US. Evidence from around the world suggests that a combination of universal pediatric screening and cascade screening strategies constitutes an effective approach to identifying heterozygous familial hypercholesterolemia (HeFH). Nevertheless, HoFH and its complications manifest much earlier in life compared to HeFH. To date, little focus has been placed on the detection of HoFH in very young children and/or infants. The 2023 Updated European Atherosclerosis Society Consensus Statement on HoFH has recommended, for the first time, broadening pediatric guidelines to include lipid screening of newborn infants. Some unique aspects of HoFH need to be considered before implementing newborn screening. As such, insights from pilot studies conducted in Europe may provide some preliminary guidance. Our paper proposes a set of actionable measures that states can implement to reduce the burden of HoFH. It also outlines key research and policy gaps that need to be addressed in order to pave the way for universal newborn screening of HoFH in the US.

Causal association of plasma circulating metabolites with nephritis: a Mendelian randomization study.

Nephritis is a pivotal catalyst in chronic kidney disease (CKD) progression. Although epidemiological studies have explored the impact of plasma circulating metabolites and drugs on nephritis, few have harnessed genetic methodologies to establish causal relationships. Through Mendelian randomization (MR) in two substantial cohorts, spanning large sample sizes, we evaluated over 100 plasma circulating metabolites and 263 drugs to discern their causal effects on nephritis risk. The primary analytical tool was the inverse variance weighted (IVW) analysis. Our bioinformatic scrutiny of GSE115857 (IgA nephropathy, 86 samples) and GSE72326 (lupus nephritis, 238 samples) unveiled anomalies in lipid metabolism and immunological characteristics in nephritis. Thorough sensitivity analyses (MR-Egger, MR-PRESSO, leave-one-out analysis) were undertaken to verify the instrumental variables' (IVs) assumptions. Unique lipoprotein-related molecules established causal links with diverse nephritis subtypes. Notably, docosahexaenoic acid (DHA) emerged as a protective factor for acute tubulointerstitial nephritis (ATIN) (OR1 = 0.84, [95% CI 0.78-0.90], p1 = 0.013; OR2 = 0.89, [95% CI 0.82-0.97], p2 = 0.007). Conversely, multivitamin supplementation minus minerals notably increased the risk of ATIN (OR = 31.25, [95% CI 9.23-105.85], p = 0.004). Reduced α-linolenic acid (ALA) levels due to lipid-lowering drugs were linked to both ATIN (OR = 4.88, [95% CI 3.52-6.77], p < 0.001) and tubulointerstitial nephritis (TIN) (OR = 7.52, [95% CI 2.78-20.30], p = 0.042). While the non-renal drug indivina showed promise for TIN treatment, the use of digoxin, hydroxocobalamin, and liothyronine elevated the risk of chronic tubulointerstitial nephritis (CTIN). Transcriptome analysis affirmed that anomalous lipid metabolism and immune infiltration are characteristic of IgA nephropathy and lupus nephritis. The robustness of these causal links was reinforced by sensitivity analyses and leave-one-out tests, indicating no signs of pleiotropy. Dyslipidemia significantly contributes to nephritis development. Strategies aimed at reducing plasma low-density lipoprotein levels or ALA supplementation may enhance the efficacy of existing lipid-lowering drug regimens for nephritis treatment. Renal functional status should also be judiciously considered with regard to the use of nonrenal medications.

Abstract PO5-02-08: Prognostic value of serum lipid levels in breast cancer patients who received neoadjuvant chemotherapy: A retrospective exploratory analysis of the prospective cohort

Abstract 【Background】 Lipid metabolism is one of the most conspicuous metabolic changes in malignant tumors. Previous studies confirmed that higher levels of “adverse lipids” might lead to poor outcomes and lipid-lowering drugs could act as a protective role in improving the prognosis of breast cancer patients. Nevertheless, few studies have clarified the impact of serum lipid levels and their changes on the tumor prognosis. Particularly for breast cancer patients treated with neoadjuvant chemotherapy, little has been studied whether their lipid levels or changes during neoadjuvant chemotherapy can serve as a valid prognostic factor. 【Methods】This study enrolled patients who received surgical treatment after neoadjuvant chemotherapy in Renji Hospital from March 2016 to December 2020. Patients were included if they were female aged 18 years or older; had pathologically confirmed unilateral invasive breast cancer; had tumor of at least 2cm in size without distant metastasis (T1-4, N0-3, M0); and underwent radical surgery for breast cancer successfully after neoadjuvant chemotherapy. We retrospectively gathered the baseline clinicopathological information and lipid metabolism-related biomarkers from electronic medical records. The study endpoints were disease free survival (DFS), overall survival (OS), relapse free survival (RFS), distance recurrence free survival (DRFS), and local recurrence free survival (LRFS). The prognostic value of each lipid levels and their variation levels were systematically evaluated and the importance of lipid biomarkers were ranked by Random Forest. 【Results】 The baseline clinicopathological information and lipid metabolism biomarkers were available from 200 eligible patients. As of the last follow-up in March 2023, 11 patients died, 24 experienced DFS events and 20 underwent RFS events. It showed no significant correlations of lipid levels before (baseline) and after (preoperative) neoadjuvant chemotherapy with any survival outcome. However, we found that the relative increase of low-density lipoprotein (LDL) led to poorer DFS (P=0.003), RFS (P=0.01), DRFS (P=0.01), and LRFS (P=0.0039), meanwhile the relative increase of total cholesterol (TC) and non-high-density lipoprotein (NHDL) during neoadjuvant period was significantly related to the worse prognosis (TC, DFS P=0.0084; NHDL, DFS P=0.031, RFS P=0.009) as well. After adjusted by multiple factors, the adverse impacts of increasing TC (DFS P=0.005; RFS P=0.026), LDL (DFS P=0.004; RFS P=0.006) and NHDL (DFS P=0.032; RFS P=0.014) on DFS or RFS were still maintained. The results of Random Forest revealed that LDL changes and Body Mass Index (BMI) ranked higher in terms of predicting survival outcomes. Based on these data, BMI &amp;gt;25.4 kg/m2 or LDL elevation &amp;gt;0.54 mmol/L were defined as High-risk Lipid Metabolism (HLM), while BMI ≤ 25.4 kg/m2 and LDL elevation ≤ 0.54 mmol/L were regarded as Low-risk Lipid Metabolism (LLM). Compared to LLM, HLM had a worse OS (P=0.026), DFS (P=0.0011) and RFS (P=0.0011). 【Conclusion】Our study demonstrated that the relative elevation of LDL, TC and NHDL levels during neoadjuvant chemotherapy is an independent prognostic risk factor for breast cancer patients. It was also the first time to propose the concept of high-risk lipid metabolism (HLM). 【keywords】Breast cancer, Lipid metabolism, Low-density lipoprotein (LDL), Body Mass Index (BMI), Prognosis.

LOWER PEAK ATRIAL LONGITUDINAL STRAIN VALUES ARE ASSOCIATED WITH OBESITY AND INSULIN RESISTANCE IN YOUNG PATIENTS WITH HYPERTENSION

Objective: The aim of the study was to compare features of left atrium remodeling in young patients with arterial hypertension (HTN) according to metabolic health status Design and method: We enrolled 83 young subjects (23 [21; 25] years, 87% males) with HTN diagnosed with office blood pressure (BP) measurement and 24-hours ambulatory BP monitoring according to ESC guidelines criteria (2018). Patients with diabetes mellitus and cardiovascular diseases were not included. We performed routine clinical examination and lab tests and two-dimensional speckle-tracking echocardiography. Patients were divided in two subgroups according to their relation to median of left atrial reservoir strain (LASr) in general population (Nielsen AB. et al., 2021. doi:10.1093/ehjci/jeab201). We estimated and compared main clinical characteristics of obesity and lipid and carbohydrates metabolism including HOMA-IR and non-insulin-based metabolic scores for insulin resistance in derived subgroups with T-test. Results: Groups had similar age, sex and BP structure. Subjects with LASr less than 39,4% (n = 48) had higher body mass index (27,2±5,0 vs 24,1±3,7, p=0,0041), waist circumference (93,4±14,0 vs 83,0±10,7, p=0,001) and waist-to-hips ratio (0,90±0,07 vs 0,84±0,07, p=0,0007). Characteristics of lipid metabolism also varied in 2 groups: in lower LASr subgroup triglycerides concentration was higher (1,53±1,06 vs 0,81±0,28, p=0,0005) and high density lipoproteins (HDL) was lower (1,18±0,28 vs 1,55±0,53, p=0,0003) while there was no significant difference in total cholesterol and low density lipoproteins levels. Fasting glucose and HOMA-IR did not differ between the groups but significant differences were observed for non-insulin-based metabolic scores: in lower LASr group METS-IR, TG/HDL ratio and TyG index were higher (41,6±9,25 vs 33,0±6,4, p&lt;0,0001; 3,38±2,94 vs 1,34±0,68, p=0,0004 and 8,55±0,60 vs 8,02±0,30, p&lt;0,0001, respectively). In reverse stepwise regression model for the general group LASr were independently associated with the level of left ventricular ejection fraction, DBP24h, METS-IR index, while the relationship with the HDL-C, SBP24h, relative wall thickness, E/e’ were lost (METS-IR index and HDL-C were included after checking the collinearity). Conclusions: young patients with HTN with lower LASr have worse metabolic status estimated with non-insulin-based metabolic scores and obesity characteristics.

The Association of Sperm DNA Fragmentation With Serum Lipid Profile Among Males With Abnormal Semen Parameters: An Analytical Cross-Sectional Study.

Through the ages, infertility, affecting 8% to 12% of couples worldwide, has been a perturbing clinical problem. Approximately 40% to 50% of all infertility cases are due to 'male factor' infertility. Semen analysis is crucial in routinely evaluating idiopathic male infertility. Studies support the idea that semen parameters are associated with serum lipids and sperm DNA fragmentation (SDF). Therefore, it is possible to evaluate male infertility by serum lipid levels, especially before assisted reproduction technology, and modify it by bringing about lifestyle modifications. This study aimed to measure the correlation of SDF with levels of total cholesterol (TC), triglycerides (TG),very low-density lipoprotein (VLDL),low-density lipoprotein (LDL), and high-density lipoprotein (HDL) among males with abnormal semen parameters. A cross-sectional analytical study was conducted in the infertility clinic of a tertiary care hospital. A total of 106 infertile males with abnormal semen analysis as per the WHO criteria (2010) were enrolled in the study. After routine semen analysis, SDF was studied using the comet assay. The serum fasting lipid profile was analyzed using the spectrophotometric kit in the autoanalyzer. The relationship of SDF with serum lipid profile parameters was analyzed. Out of 106 infertile men, 52% (n = 55) had severe SDF. A modest positive correlation was observed between SDF (percentage of DNA in comet tail) and serum lipid values (serum TG, serum LDL, and serum VLDL). Our study is novel in its research on the correlation between SDF and serum lipid values. Based on the findings of our study, it can be concluded that a significant level of SDF was observed in men with high levels of serum TG, LDL, and VLDL. This provokes a potential relationship between sperm DNA integrity and serum lipid profile, which warrants further research.

The effect of Dracocephalum subcapitatum hydroalcoholic extract on dexamethasone-induced hyperlipidemic rats.

Recent data show the antihyperlipidemic activities of some plants belonging to the genus Dracocephalum. In this study, the effects of hydroalcoholic extract of D. subcapitatum (O. Kuntze) Lipsky aerial parts were evaluated in a model of hyperlipidemia induced by dexamethasone. The extract was prepared by maceration method and its total phenolic content was determined. Seven groups of 6 Wistar rats were used as follows: group 1 (normal control) received vehicle; group 2 (extract control) treated only with 200 mg/kg D. subcapitatum; group 3 (hyperlipidemia control) received dexamethasone (10 mg/kg/day, subcutaneously); group 4 (reference) received dexamethasone and atorvastatin (40 mg/kg, orally), and groups 5-7 (test groups) received dexamethasone and simultaneously treated orally with 50, 100, or 200 mg/kg D. subcapitatum. All treatments were done for 1 week. Serum lipid profile, fasting blood glucose, malondialdehyde concentration, and liver histopathology were examined. Total phenolic content was 77.34 ± 4.9 mg/g as gallic acid equivalent. Treatment with D. subcapitatum (200 mg/kg) meaningfully declined triglycerides, total cholesterol, low-density lipoprotein, very low-density lipoprotein, blood glucose, alanine aminotransferase, aspartate aminotransferase, and malondialdehyde levels, and alleviated hepatic steatosis in dexamethasone-induced dyslipidemic rats. Findings of the current study suggest that D. subcapitatum may be effective in the management of hyperlipidemia. Further studies are necessary to determine the clinical efficacy of this treatment and to understand the underlying mechanisms responsible for its ability to lower lipid levels.

Isotretinoin's Effect on Fasting Lipid Profile in Acne Patients.

To determine the isotretinoin's effect on fasting lipid profile in patients with acne. Observational study. Place and Duration of the Study: Outpatient Department of Dermatology, Dow International Medical College, Dow University of Health Sciences, Karachi, Pakistan, from 22nd June to 21st December 2022. Patients of clinically moderate and severe acne were selected and prescribed a dose of 0.5mg /kg cap isotretinoin for 6 months. They were advised to get a fasting lipid profile at the baseline and then after two months of isotretinoin therapy. National Cancer Institute Common Terminology Criteria for Adverse Events v5.0 grading system and Adult Treatment Panel III were used for the grading of abnormalities. McNemar Bowker test was used to assess the difference in variables [serum triglycerides (TGs), cholesterol, high-density lipoproteins (HDL), and low-density lipoproteins (LDL)] at the baseline and after 2 months follow-up. A total of 214 patients were evaluated. After 2 months of isotretinoin therapy, TGs and cholesterol levels were elevated to higher grade in 2% of the patients. Likewise in 1% of patients, LDL levels rised to higher grade. Moreover, HDL levels declined to lower grade in 2% of the patients taking isotretinoin. Insignificant alterations in the various serum lipid parameters were observed in acne patients during isotretinoin therapy. It is advisable to obtain a baseline fasting lipid profile in all acne patients on isotretinoin and repeated in those with baseline abnormal levels and in patients with a clinical sign of metabolic syndrome and a family history of dyslipidemias. Acne, Hyperlipidemias, Isotretinoin, Laboratory monitoring.

Impact of Dyslipidemia on Tear Film and Meibomian Gland Dysfunction: A Cross-Sectional Study of the Interplay between Serum Lipid Profile and Ocular Surface Health.

To determine the relationship between dyslipidemia and dry eye disease (DED), as well as its influence on tear film and meibomian glands. This cross-sectional study included 40 patients with a mean age of 35.2 ± 13.9 years without any history of dyslipidemia. DED and serum lipid profile were evaluated after 8 hours of fasting. Patients were classified according to serum lipid levels with the following cut-off values: total cholesterol (TC) (200 mg/dl), high-density lipoprotein (HDL) (40 mg/dl), low-density lipoprotein (LDL) (130 mg/dl), and triglycerides (TG) (150 mg/dl). The relationship between serum lipid levels and DED was analyzed with the following variables: dry eye questionnaire-5 (DEQ-5), first (F-NIBUT) and average (A-NIBUT) noninvasive breakup time, tear meniscus height (TMH), lipid layer grade (LLG), conjunctival bulbar redness (CBR), and upper (U-LAMG) and lower (L-LAMG) loss area of meibomian glands. Regarding tear film, patients with elevated TC and LDL levels reported significantly higher DEQ-5 scores and TMH (P < 0.05), while those with lower HDL levels showed significantly higher LLG (p < 0.05). Regarding MGD, patients with elevated TC, LDL, and TG, as well as lower HDL levels showed significantly higher L-LAMG (p < 0.05). HDL was correlated with LLG (p < 0.05), while TC was correlated with TMH (p < 0.05) and L-LAMG (p < 0.05), respectively. Disorders in TC, HDL, LDL, and TG levels were associated with DED, having an impact on the tear film and meibomian glands, specifically in DEQ-5 scores, LLG, and L-LAMG.

Jatropha curcas L. Leaf Extract Effects on Blood Pressure and Lipid Levels in Hypertensive Rats with High-Fat Diet

Background: One of the main risk factors for cardiovascular diseases such as coronary atherosclerotic heart disease (CAHD) is dyslipidaemia or high levels of low-density lipoprotein (LDL) and triglycerides (TG) and low levels of high-density lipoprotein (HDL). Hypertension is also a cause of cardiovascular disease. One potential plant to lower LDL levels and blood pressure is Jatropha curcas, which is known to contain saponins, polyphenols, and flavonoids. Objective: The purpose of this study was to determine the effect of the ethanol extract of Jatropha curcas leaves (EEJCL) on blood pressure, LDL levels, and HDL levels in hypertensive rats given a high-fat diet. Methods: This study is an experimental study with a pretest-posttest control group design on male Wistar strain rats. Rats were divided into seven groups, namely the normal group, control group (induced with NaCl and given a high-fat diet), Captopril group, Simvastatin group, and EEJCL groups given doses of 1.8, 2.7, and 4.05 g/kg BW. The data obtained were analysed using the One-Sample Kolmogorov-Smirnov Test, Homogeneity of Variance, One-Way ANOVA, and Tukey Test. Results: The results showed that the administration of EEJCL could significantly lower LDL levels and blood pressure and increase HDL levels (p &lt; 0.05) at doses of 1.8, 2.7, and 4.05 g/kg BW, and the dose of 4.05 g/KgBW was the most optimal dose. Conclusion: EEJCL has a potential for development in the treatment of hypertension and dyslipidaemia.

Impact of the inclusion of calcium soap in feed on intestinal histology and blood lipid profile of native chickens

The aim of this study was to examine the impact of the inclusion of calcium soap in feed on the intestinal histology and blood lipid profile of native chickens. This study used 192 native chickens aged 6 weeks with homogeneous body weight which were randomized into 4 types of treatment and 6 replications and each replication used 48 chickens with homogeneous body weight. The four types of treatment were: Group of chickens fed without the addition of Ca-PFAD as a control (chicken Group A); chicken feed with the addition of 2% Ca-PFAD (chicken Group B); chicken feed with the addition of 4% Ca-PFAD (chicken Group C); and chicken feed with the addition of 6% Ca-PFAD (chicken Group D). The results showed that the height of the jejunal villi in chicken groups C and D was significantly (P&lt;0.05) higher than the control (chicken group A). Likewise, the depth of the jejunum crypts of Group C and D chickens was significantly (P&lt;0.05) deeper than that of Group A chickens. The inclusion of 2-6% Ca-PFAD in the feed significantly (P&lt;0.05) improved the blood lipid profile of native chickens. It was concluded that administration of calcium soap (Ca-PFAD) in feed can increase the height of the villi and the depth of the crypts of the intestinal jejunum. On the other hand, at the 4% level, giving calcium soap in feed can reduce cholesterol and Low Density Lipoprotein (LDL) levels, as well as increase triglyceride and High Density Lipoprotein (HDL) levels in native chicken.

Interaction of periodontal clinical indicators in metabolic syndrome and nonalcoholic fatty liver disease: Implications for preventive interventions

IntroductionThe behavior of periodontal clinical indicators in metabolic syndrome (MetS) and fatty liver disease (NAFLD) are not clearly defined. It’s even considered that high-risk cases for NAFLD are currently underreported or not identified in a timely manner. The aim of the study is to elucidate the interaction of periodontal clinical indicators in MetS and NAFLD. Materials and methods: 336 patients were eligible because they met the diagnostic criteria for metabolic syn-drome and nonalcoholic fatty liver disease. Those selected were randomly selected for a cross-sectional study. Metabolic status and non-alcoholic fatty liver disease were measured using the MetS Metabolic Syndrome Diagnostic Criteria (NCEP/ATP-III) and laboratory tests, respectively. In addition, periodontal clinical indicators were evaluated: probing depth, clinical attachment, plaque index and gingival bleeding. ResultsThe association for NAFLD and probing depth was p = 0.736. The association for MetS and probing depth was p = 0.598. For NAFLD and clinical attachment loss, the association was p = 0.751. For MetS and clinical attachment loss, the association was p = 0.435. The plaque index for MetS was p = 0.238. The plaque index for NAFLD was p = 0.269. The gingival bleeding association for NAFLD was p = 0.673 and for MetS was p = 0.522. ConclusionsPeriodontal clinical indicators of metabolic syndrome were as-sociated with elevated serum levels of low-density lipoproteins (LDL), HDL-cholesterol, and triglycerides. However, when comparing the values in NAFLD and MetS, a greater significance is evident in the first study group.

USP18 Curbs the Progression of Metabolic Hypertension by Suppressing JAK/STAT Pathway.

Hypertension is a pathological state of the metabolic syndrome that increases the risk of cardiovascular disease. Managing hypertension is challenging, and we aimed to identify the pathogenic factors and discern therapeutic targets for metabolic hypertension (MHR). An MHR rat model was established with the combined treatment of a high-sugar, high-fat diet and ethanol. Histopathological observations were performed using hematoxylin-eosin and Sirius Red staining. Transcriptome sequencing was performed to screen differentially expressed genes. The role of ubiquitin-specific protease 18 (USP18) in the proliferation, apoptosis, and oxidative stress of HUVECs was explored using Cell Counting Kit-8, flow cytometry, and enzyme-linked immunosorbent assays. Moreover, USP18 downstream signaling pathways in MHR were screened, and the effects of USP18 on these signaling pathways were investigated by western blotting. In the MHR model, total cholesterol and low-density lipoprotein levels increased, while high-density lipoprotein levels decreased. Moreover, high vessel thickness and percentage of collagen were noted along with increased malondialdehyde, decreased superoxide dismutase and catalase levels. The staining results showed that the MHR model exhibited an irregular aortic intima and disordered smooth muscle cells. There were 78 differentially expressed genes in the MHR model, and seven hub genes, including USP18, were identified. USP18 overexpression facilitated proliferation and reduced apoptosis and oxidative stress in HUVECs treated with Ang in vitro. In addition, the JAK/STAT pathway was identified as a USP18 downstream signaling pathway, and USP18 overexpression inhibited the expression of JAK/STAT pathway-related proteins. Conclusively, USP18 restrained MHR progression by promoting cell proliferation, reversing apoptosis and oxidative stress, and suppressing the JAK/STAT pathway.

Influence of Dietary Probiotic and Alpha-Monolaurin on Performance, Egg Quality, Blood Constituents, and Egg Fatty Acids' Profile in Laying Hens.

This work was designed to evaluate the advantages of using multi-strain probiotics feed (Bacillus subtilis, Bacillus licheniformis and Clostridium butyricum) (PRO) and alpha-monolaurin (AML) on laying performance, criteria of egg quality, blood parameters, and yolk fatty acids' profile in laying hens. One hundred forty of Bovans brown laying hens at 45 weeks old (25th week of egg production) were randomly allocated into four groups, with seven replicates of five birds each in a complete randomized design. The first group was fed a basal diet without feed additives (0g/kg diet), and the second, third, and fourth groups received diets containing 1g PRO, 1g AML, and 1g PRO + 1g AML/kg diet, respectively. No significant impacts of PRO, AML, or their mixture on body weight (BW), body weight gain (BWG), feed intake (FI), or egg weight. Egg production, egg mass, and feed conversion ratio (FCR) were enhanced by 1g PRO/kg and /or 1g AML/kg supplementation in laying hen diets. Furthermore, egg shape index, eggshell thickness, and yolk color were statistically higher by PRO and AML supplementation at 55 weeks. However, oviduct, infundibulum, and uterus weights were significantly decreased by 1g PRO or/and 1g AML. Additionally, total cholesterol, triglycerides, low density lipoprotein (LDL), glucose, and glutamate pyruvate transaminase (GPT) levels were decreased by PRO and AML supplementation. In conclusion, it seems that dietary inclusion with 1g PRO/kg, 1g of AML/kg, and 1g PRO + 1g AML improved egg production, egg mass, FCR, and yolk fatty acids profile and lowered total cholesterol and malondialdehyde (MDA) contents in laying hens.

Exploring the bi-directional relationship between periodontitis and dyslipidemia: a comprehensive systematic review and meta-analysis.

As periodontitis and dyslipidemia are diseases that occur with high incidence, the relationship between them has attracted much attention. Previous studies on these diseases have tended to focus on lipid parameters and periodontitis, we aimed to investigate the relationship between dyslipidemia and periodontitis. A comprehensive search to identify the studies investigating the relationship between dyslipidemia and periodontitis was performed on PubMed, Web of Science and Cochrane Library before the date of August, 2023. Studies were considered eligible if they contained data on abnormal blood lipid parameters and periodontitis. Studies that reported mean differences and 95% confidence intervals or odds ratios were used. A total of 73 publications were included in the meta-analysis. Hyper total cholesterol (TC), triglycerides (TGs), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) and lower high-density lipoprotein (HDL) levels are risk factors for periodontitis. Periodontal disease is a risk factor for high TG and low HDL levels. Three months after periodontal treatment, the levels of TC, TG and HDL were significantly improved, and statin treatment only improved gingival index (GI) levels compared to that of the dietary control. The findings reported here suggest that the mutual promotion of periodontitis and dyslipidemia can be confirmed. Non-surgical periodontal therapy may improve lipid abnormalities. It can't be demonstrated whether systematic application of statins have a better effect on the improvement in periodontal status in patients with dyslipidemia compared to that of the control.

Erjingwan and Alzheimer's disease: research based on network pharmacology and experimental confirmation.

Alzheimer's disease (AD), a challenging neurodegenerative condition, has emerged as a significant global public health concern. The Chinese medicine decoction Erjingwan (EJW) has shown promising efficacy in AD treatment, though its mechanism remains unclear. This study aims to elucidate the mechanism by which EJW treats AD through network pharmacology analysis and in vivo experiments. We identified EJW's components using the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database and determined AD-related targets from various databases. A network comprising herbs-compounds-targets was established, and EJW's core targets were ascertained through protein-protein interaction (PPI) analysis. This study assessed the cognitive abilities of APP/PS1 mice using Morris water mazes and Y mazes, in addition to analyzing blood samples for triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels. Brain tissues were examined histologically with HE staining, Nissl staining, and immunohistochemistry (IHC) for amyloid β-protein (Aβ) detection. Superoxide dismutase (SOD), reactive oxygen species (ROS), Interleukin-1β (IL-1β), and Interleukin-6 (IL-6) levels in the hippocampal region were measured by ELISA. mRNA expression of apolipoprotein A-I (APOA-I), apolipoprotein B (APOB), apolipoprotein E4 (APOE4), advanced glycation end products (AGE), the receptor for AGE (RAGE), and nuclear factor kappa-B (NF-κB) was evaluated by quantitative PCR (q-PCR). Western blotting was used to detect the expression of AGE, RAGE, NF-κB, and Tau protein. Screening identified 57 chemical components and 222 potential targets of EJW. Ten core targets for AD treatment were identified, with enrichment analysis suggesting EJW's effects are related to lipid metabolism and AGEs/RAGE pathways. EJW enhanced learning and memory in APP/PS1 mice, protected neuronal structure in the hippocampal region, reduced Aβ deposition, and altered levels of TG, TC, LDL, IL-1β, and IL-6, and the expression of APOE4, AGEs, RAGE, NF-κB, and Tau protein, while increasing SOD, APOA-I, and APOB mRNA expression. The study identified four core components of EJW-iosgenin, baicalein, beta-sitosterol, quercetin-and ten core targets including AKT1, IL6, VEGFA, TP53, CASP3, for treating AD. Experimental results demonstrate EJW's capacity to modulate lipid profiles, reduce pathological markers such as Aβ1-42, Tau, IL-6, IL-1β, reactive oxygen species, SOD, and enhance cognitive functions in APP/PS1 mice, potentially through inhibiting the AGEs/RAGE/NF-κB pathway.

Effect of per os administration of fucoxanthin alcoholic and oil extracts to Balb/c mice on biochemical parameters and serum cytokine level

Microalgae are a source of various biologically active substances, including carotenoids. One of the carotenoids of diatom microalgae is fucoxanthin, which has antioxidant, antimicrobial, antitumour and anti-inflammatory properties that can be used in the treatment of a wide range of human and animal pathologies. The aim of the study was to investigate the effect of alcohol and oil extract of fucoxanthin on biochemical parameters and levels of serum cytokines in mice during intragastric administration. Material and methods. Fucoxanthin extracts from the microalga Nanofrustulum shiloi were used. Mice of Balb/c strain were intragastrically administrated with 0.5 ml of oil (500 μg/ml) or alcoholic extract of fucoxanthin (187.5 μg/ml), mice in the comparison group were given 0.5 ml of olive oil or 45% ethyl alcohol once a day within 5 days. On the 8th day, blood serum was obtained and the level of albumin, triglycerides, cholesterol, low (LDL) and high density lipoproteins (HDL), urea, uric acid, creatinine, aspartate (AST) and alanine aminotransferases (ALT), lactate, stable nitric oxide (NO) metabolites (nitrites), cytokines (IL-1β, IL-6, IL-10, TNF-α, IFN-γ) was determined using ELISA with photometric detection. Results and discussion. In the comparison group, ethyl alcohol promoted an increase in serum triglyceride, cholesterol, LDL, HDL, ALT, AST, nitrite, IL-10, IFN-γ and TNF-α content compared to intact animals. Fucoxanthin alcoholic extract administration increased the level of LDL, HDL, uric acid, TNF-α and decreased albumin, cholesterol, uric acid, creatinine, ALT, AST, IL-6 content compared to control. The olive oil group showed a decrease in serum triglycerides, cholesterol, urea, uric acid, ALT and AST content but an increase in LDL, HDL, nitrite level compared to the control. Administration of fucoxanthin oil extract to animals decreased albumin, triglycerides, cholesterol, HDL, uric acid, ALT, AST, lactate, IL-6, IL-10 compared to control. Conclusions. Thus, it was discovered that fucoxanthin in Balb/c mice contributes to a decrease in hepatic synthetic function, as evidenced by the change in the concentration of albumin, triglycerides, uric acid), influences energy metabolism (creatinine, lactate), cell membrane stability (cholesterol, LDL, HDL), serum transaminase activity, pro- and anti-inflammatory cytokines content.
