Lipid profile and mortality in patients with pulmonary thromboembolism; a systematic review and meta-analysis.

Acute pulmonary thromboembolism (PTE) is a life-threatening disease. Considering the availability and accessibility of assessing the serum lipids, this study aims todefine the predictive value of lipid profile, as well as the history of lipid disorders, for the mortality of PTE patients. Clinical studies, in which the relation of lipid profile, including triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and total cholesterol, as well as history of imbalance of lipids, with mortality of PTE patients was reported, were included. Non-English articles, reviews, letters, editorials, and non-English papers were excluded. A systematic search was conducted in PubMed, Embase, Scopus, and Web of Science databases. Therisk of bias was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal tools and CMA 4 was utilized forthe quantitative synthesis. Out of 3,724 records, six studies were included inthis systematic review. Lipid profile is suggested as a prognostic marker for survival in patients with PTE so higher initial serum HDL, LDL, and total cholesterol levels were associated with lower mortality rates in PTE patients. In addition, dyslipidemia was found to be associated withmortality of PTE patients. Based on the quantitative synthesis, there was a greater serum level of HDL in thesurvival group (standardized mean difference:-0.98; 95 %CI:-1.22 to-0.75; p-value<0.01). Mortality is lower in PTE patients with greater serum lipid levels; therefore, the early prognosis of PTE maybe ascertained by measuring serum lipids within the first 24 h of admission.

β-sitosterol alleviates atherosclerosis by regulating catalase

The aim of this study is to investigate the main active components of Gegen (Puerariae Lobatae Radix) on atherosclerosis and its mechanism of action. Bioinformatics analysis showed that β-sitosterol was the most likely active ingredient to mediate the anti-atherosclerotic effects. In vivo experiments showed that β-sitosterol inhibited plaque formation and platelet activation, and decreased serum total cholesterol (TC) and triglyceride (TG) levels. In vitro experiments showed that β-sitosterol can inhibit lipid deposition and phenotypic transformation of vascular smooth muscle cells (VSMCs). However, knocking down catalase (CAT), the direct target of β-sitosterol, not only promoted lipid deposition and phenotypic transformation of VSMCs, but also activated the PI3K/Akt/mTOR pathway, and the mTOR inhibitor (ink-128) can eliminate the effect of CAT knockdown, suggesting that β-sitosterol may inhibit lipid deposition and phenotypic transformation of VSMCs by activating CAT and silencing the PI3K/Akt/mTOR signaling pathway, thereby alleviating atherosclerosis.

The synergistic effects of dietary protein and stocking density on performance, digestive enzymes, and hemato-biochemistry parameters of juvenile striped catfish (Pangasianodon hypophthalmus)

This experiment was designed to examine the impacts of different dietary protein levels (DPLs) and their interaction on the growth and some physiological indices of juvenile striped catfish, Pangasianodon hypophthalmus, reared at different stocking densities (SDs) for 15 weeks. A total of 1440 striped catfish (initial weight = 10.0 ± 2.2 g) were randomly allocated into six equal treated groups (three replicates per treated group). Fish were fed two DPLs of 25 % and 30 % and reared under different SDs of 20, 40, and 60 fish/m3. The obtained results indicated that with increasing DPL, growth parameters, and digestive enzyme activities, the liver function enzyme activities, serum protein constituents' levels, and concentrations of thyroid hormones significantly increased, while levels of serum glucose, total cholesterol, and triglycerides remarkably decreased. On the other hand, increasing SD negatively affects growth, digestive and liver enzyme activities, some hematological parameters, and fish-body chemical analysis. The interaction between DPLs and different SDs significantly improved the most estimated parameters with increasing DPLs despite intensifying SDs. In general, afforded striped catfish diets containing 30 % DPL and stocked at 20 fish/m3 presented the best performance, consumed feed efficiency, and health status. Thus, the interaction between DPLs and SDs demonstrated the favorable benefits of increasing DPLs by diminishing some of the adverse impacts generated by high SDs, which may subsequently lead to high production and increased revenues for fish farmers.

Effects of rosuvastatin on serum asymmetric dimethylarginine levels and incidence of long-term cardiovascular events in patients with hyperlipidaemia and H-type hypertension.

Aims/Background Rosuvastatin is a common lipid-lowering statin on the market, but its impact on the incidence of long-term cardiovascular events is not well clarified. This study aimed to explore the effects of rosuvastatin on serum asymmetric dimethylarginine (ADMA) levels and the incidence of long-term cardiovascular events in patients with hyperlipidaemia and H-type hypertension. Methods This retrospective study included 158 patients with hyperlipidaemia and H-type hypertension who were treated in the Hebei Cangzhou Hospital of Integrated Traditional Chinese Medicine and Western Medicine from August 2015 to August 2016. The patients were divided into an occurrence group and a non-occurrence group according to the occurrence of long-term cardiovascular events following the resuvostatin treatment. The changes in blood lipids, blood pressure, serum ADMA levels and vascular endothelial function indexes before and after treatment were compared, and the effect of ADMA on the occurrence of long-term cardiovascular events and its predictive efficacy were analysed using the Spearman correlation test and receiver operating characteristics (ROC) curve. Results After treatment, the levels of serum total cholesterol, low-density lipoprotein cholesterol, triglyceride, serum ADMA and blood pressure became significantly lower (p < 0.001), with high-density lipoprotein cholesterol exhibiting no significant difference. Twenty-two cases developed long-term cardiovascular events after the treatment, with an incidence of 13.92%. The occurrence group had significantly higher serum ADMA levels than the non-occurrence group (p < 0.001). The rosuvastatin treatment also lowered the levels of endothelin-1 and high-sensitivity C-reactive protein and increased the nitric oxide level (p < 0.001). Spearman correlation analysis showed that serum ADMA levels were positively correlated with the occurrence of long-term cardiovascular events (r=0.462, p < 0.001). Meanwhile, according to the ROC curve, serum ADMA had a good predictive efficacy for long-term cardiovascular events, with an area under the curve of 0.885 (95% confidence interval 0.808-0.963; p < 0.001). Conclusion Rosuvastatin can reduce ADMA levels and exert vascular protective effects. The increase in serum ADMA levels is closely related to the occurrence of long-term cardiovascular events in patients with hyperlipidaemia and H-type hypertension, serving as a potential clinical predictor to guide disease prevention and treatment.

Effects of Sesamin in Animal Models of Obesity-Associated Diseases: A Systematic Review and Meta-Analysis.

As living standards have improved and lifestyles have undergone changes, metabolic diseases associated with obesity have become increasingly prevalent. It is well established that sesamin (Ses) (PubChem CID: 72307), the primary lignans in sesame seeds and sesame oil, possess antioxidant and anti-inflammatory effects. In this study, a systematic review and meta-analysis of the effects of Ses on animal models of obesity-related diseases was performed to assess their impact on relevant disease parameters. Importantly, this study sought to provide insights for the design of future human clinical studies utilizing Ses as a nutritional supplement or drug. This study conducted a comprehensive search in PubMed, Web of Science, Embase, Scopus, and the Cochrane Library, identifying English language articles published from inception to April 2023. The search incorporated keywords such as "sesamin," "obesity," "non-alcoholic fatty liver disease," "type 2 diabetes mellitus," and "metabolic syndrome." The meta-analysis included 17 articles on non-alcoholic fatty liver disease, type 2 diabetes, and metabolic syndrome. Overall, the pooled results demonstrated that Ses significantly reduced levels of total serum cholesterol (P = .010), total serum triglycerides (P = .003), alanine transaminase (P = .003), and blood glucose (P < .001), and increased high-density lipoprotein cholesterol levels (P = .012) in animal models of nonalcoholic fatty liver disease. In the type 2 diabetes model, Ses mitigated drug-induced weight loss (P < .001), high-fat-diet-induced weight gain (P < .001), and blood glucose levels (P = .001). In the metabolic syndrome model, Ses was associated with a significant reduction in body weight (P < .001), total serum cholesterol (P < .001), total serum triglycerides (P < .001), blood glucose (P < .001), and alanine transaminase levels (P = .039). The meta-analysis results of this study suggest that Ses supplementation yields favorable effects in animal models of obesity-related diseases, including hypolipidemic, insulin-lowering, and hypoglycemic abilities, as well as organ protection from oxidative stress and reduced inflammation.

Alleviation of High-Fat Diet-Induced Hyperlipidemia in Mice by Stachys sieboldii Miq. Huangjiu via the Modulation of Gut Microbiota Composition and Metabolic Function.

Hyperlipidemia is a chronic disease that is difficult to cure, and long-term pharmacotherapy may have negative consequences. Dietary therapy is a very promising strategy, and Chinese rice wine (Huangjiu) will play an important role because of its many biologically active components. In this work, the alleviating effect of Stachys sieboldii Miq. Huangjiu (CSCHJ) on high-fat diet-induced hyperlipidemia in mice was investigated, which is brewed from the wheat Qu with the addition of Stachys sieboldii Miq. and contains 15.54 g/L of polysaccharides. The experimental results showed that CSCHJ inhibited appetite, reduced body weight and blood sugar levels, and downregulated the serum levels of total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) while concurrently upregulating high-density lipoprotein cholesterol (HDL-C) in the high-fat diet-induced hyperlipidemia mice. At the same time, it was discovered that alcohol worsens hyperlipidemia symptoms and related physiological markers, implying that CSCHJ polysaccharides may play a role in hyperlipidemia treatment. Through the assessment of organ indices, liver and kidney function, and tissue staining, CSCHJ demonstrated efficacy in repairing liver, kidney, and colon mucosal damage in hyperlipidemic mice. Furthermore, 16S rDNA sequencing and gas chromatography studies revealed that CSCHJ effectively restored the intestinal microbial structure and enhanced the quantity of fecal short-chain fatty acids (SCFAs) in hyperlipidemic mice. Therefore, the alleviating effect of CSCHJ on hyperlipidemia in mice may be attributed to its regulation of energy metabolism by repairing liver, kidney, and colon mucosal damage and restoring the gut microbiota structure, among other mechanisms. Overall, our findings provide evidence that CSCHJ contains active ingredients capable of alleviating hyperlipidemia, thereby laying a theoretical foundation for the extraction of bioactive substances from Huangjiu for future medical or dietary use.

Effects of Mixed Organic Acids and Essential Oils in Drinking Water on Growth Performance, Intestinal Digestive Capacity, and Immune Status in Broiler Chickens.

In order to evaluate the effects of acidifiers and essential oils in drinking water on growth, intestinal digestive capacity, and immune status in broilers, a total of 480, 1-day-old Arbore Acres broilers were randomly assigned to four treatments including normal tap water (Ctr) and tap water supplemented with acidifier I (ACI), acidifier I and essential oils (ACI+EO), and acidifier II (ACII). Both ACI+EO and ACII increased final body weight. The pH value of the crop and gizzards was reduced by ACI+EO, and ACII decreased the pH values of the proventriculus and gizzards (p < 0.05). Compared with control group, ACI, ACI+EO, ACII significantly enhanced lipase activity in jejunum but ACII decreased the level of serum total cholesterol and total triglyceride (p < 0.05). Compared with the control group, ACI+EO and ACII significantly increased the relative weight of the spleen, increased the level of serum IgA and IgM, and decreased E. coli in excreta, while ACII significantly decreased Salmonella in excreta (p <0.05). All treatments significantly increased Lactobacillus in excreta. In conclusion, ACI+EO improved immune status and ACII was effective in reducing Salmonella and promoting Lactobacillus, contributing to intestinal health.

The Improvement Effects of a Nutritional Fortifier on the Reproductive Performance, Sex Steroid Hormone Production, and Health of the Striped Bamboo Shark Chiloscyllium plagiosum.

To explore a method of improving the reproductive performance of the striped bamboo shark, three groups (D0, D1, and D2) of mature individuals were fed squid with (D1 and D2) or without (D0) a nutritional fortifier during the breeding seasons of 2022 and 2023. Compared with the D0 group, the D1 and D2 groups had an increase of 20.90% and 31.34% in total eggs, increases of 32.73% and 41.82% in the proportion of lecithal eggs, and a total 119.07% increase in hatching rate, respectively, in 2022. In 2023, the corresponding increase was 17.12% and 9.91% in total eggs, 19.63% and 12.15% in the proportion of lecithal eggs, 43.37% and 43.94% in fertilization rate, 23.94% and 22.22% in hatchability rate, and 66.70% and 8.70% in the survival rate of fry. Moreover, the levels of serum estradiol, testosterone, progesterone, albumin, and total antioxidant capacity and the levels of ARA, EPA, DHA, n-3 PUFA, and n-6 PUFA in both serum and lecithal eggs significantly increased, while the levels of serum triglyceride and total cholesterol were the opposite (p < 0.05). The results demonstrate that feeding the sharks with a nutritional fortifier can increase spawn production and the quality of eggs, regulate the production of sex steroids, and improve the nutrition of eggs and the health of broodstocks.

Platycodon D reduces obesity and non-alcoholic fatty liver disease induced by a high-fat diet through inhibiting intestinal fat absorption.

Platycodin D (PD) has been reported to treat metabolic diseases, including non-alcoholic fatty liver disease. In addition, platycodin D has been reported to activate intestinal 5'AMP-activated protein kinase (AMPK) phosphorylation levels, thereby reducing lipid absorption. Therefore, the aim of this study is to explore whether PD activation of intestinal AMPK and reduced lipid absorption can improve non-alcoholic fatty liver disease. Clean-grade male C57/BL mice were fed a high-fat diet (HFD) (containing 60% calories) for 16 weeks, and oral PD (10mg/kg/day) was administered at the same time. The liver and intestines were the collected, and the intestines were tested. The expressions of lipid absorption genes (CD36, NPC1L1, and ApoB), the serum total triglyceride (TG) and total cholesterol (TC) levels in the intestines and livers, the fecal free fatty acid (FFA) levels, and the expression of AMPK phosphorylated proteins in the intestines were examined using Western blot analyses. The lipid distribution in the livers, intestines, and fat was detected using Oil Red O and hematoxylin and eosin (H&E) staining. A colon cancer cell line (Caco2) was used to confirm the effect of PD on the cellular lipid uptake in vitro. In addition, serum inflammatory factors and liver enzymes were measured to clarify the impact of PD on the circulation of metabolic syndrome. Leptin-deficient mice (OB) were then used to further explore the improvement of PD on body weight and blood lipids. PD had a very significant therapeutic or preventive effect on metabolic syndrome and fatty liver induced by a high-fat diet. PD improved body weight, insulin sensitivity, and glucose tolerance in mice fed a high-fat diet and also prevented non-alcoholic fatty liver disease, reduced blood lipid levels, and increased fecal lipid excretion. In addition, PD reduced lipid absorption by activating the intestinal AMPK protein, which may have involved the inhibition of the gene expression levels of intestinal lipid absorption genes (CD36, NPC1L1, and ApoB). The combined effect of these factors improved hepatic lipid accumulation and lipid accumulation in adipose tissue. It was further found that PD also improved the body weights and blood lipid levels of leptin-deficient mice (OB) mice. PD had a very strong therapeutic effect on mice under a high-fat diet. PD reduced high-fat diet-induced obesity and non-alcoholic fatty liver disease by inhibiting intestinal fat absorption.

The therapeutic effect of NRF2 activator, ezetimibe, in cardiac cachexia.

Heart failure (HF) is caused by functional and structural irregularity leading to impaired ejection or filling capacity of the heart. HF leads to chronic inflammatory conditions in the heart leads to weight loss, anorexia, and muscle atrophy known as cachexia. The present study was carried out to investigate the role of Ezetimibe, an NRF2 activator, in cardiac cachexia and to develop a treatment strategy for cardiac cachexia. Balb/c mice of either sex at 6-8 weeks of age were given 2 mg/kg of doxorubicin in 0.9% sodium chloride solution intraperitoneally (i.p.) for the alternate days for the first week and then once a week for the next 4 weeks. After induction of cardiac atrophy, treatment with Ezetimibe (1.5 mg/kg, p.o) was given for the next 4 weeks. In the cardiac cachectic animals, a significant decrease in body weight, food, and water intake was observed. Cardiac cachectic animals showed a significant increase in serum glucose, total cholesterol, LDL, triglyceride, VLDL, CK-MB, LDH, and CRP levels. Cardiac atrophic index, heart weight to body weight ratios (HW/BW), right ventricular weight to heart weight ratios (RV/HW), and left ventricular weight to heart weight ratios (LV/HW), were significantly decreased in cardiac cachectic animals. The weights of the skeletal muscles such as EDL, gastrocnemius, soleus, tibialis anterior, and quadriceps muscles, and the weight of adipose tissue such as subcutaneous, visceral, perirenal, and brown adipose tissue were significantly decreased in the cardiac cachectic group relative to the normal group. Treatment with ezetimibe improves body weight, food intake, and water intake. Ezetimibe decreases serum glucose, total cholesterol, LDL, triglyceride, VLDL, CK-MB, LDH and CRP levels. Cardiac atrophic markers such as HW/BW, RV/HW, and LV/HW were improved. The weight of skeletal muscles and adipose tissue was increased after treatment with ezetimibe. Our data showed that the NRF2 activator, Ezetimibe produces a beneficial effect on cardiac cachexia in the doxorubicin-induced cardiac cachexia model. Ezetimibe was successful to reduce the levels of inflammatory cytokines, ameliorate the effects on cardiac muscle wasting, lipid levels, fat tissues, and skeletal muscles.

Cholesterol-lowering effect of Pediococcus strains isolated from mother’s milk in mice

PurposeThe Pediococcus strains belong to the group of lactic acid bacteria (LAB). This study aims to isolate and identify the Pediococcus spp. from mother’s milk, and investigate their tolerance to low pH and bile salts, antibacterial activity, attachment to HT-29 cells and effect on cholesterol-lowering and digestive enzymes in mice.Design/methodology/approachPediococcus species were isolated from mother’s milk, then tested for tolerance to acid and bile salts, their antibacterial effect and attachment to HT-29 cell line. In mice experiment, the levels of triglyceride (TG), total cholesterol (TC), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C) and digestive enzymes such as amylase and lipase in serum of mice were measured after administration of 108 CFU/mL bacterial suspension.FindingsA total of 24 Pediococcus spp. including 16 isolates of Pediococcus pentosaceus and 8 isolates of Pediococcus acidilactici were isolated. Fifteen isolates (62.5%) were able to survive in low pH and bile salt concentration. Ten isolates (41.6%) exhibited the most powerful inhibitory effects against both Gram-positive and Gram-negative bacterial pathogens. A total of four Pediococcus isolates (16.67%) showed strong attachment to HT-29 cells. In contrast to HDL-C and amylase, the serum levels of TC, TG and LDL-C were reduced and lipase was elevated significantly following administration of mother milk-derived Pediococcus isolates.Originality/valueThe Pediococcus isolates demonstrated good probiotic properties in particular cholesterol-lowering ability in mice. Thus, after more studies they can be considered as probiotic strain(s).

Zinc finger 259 gene polymorphisms in Egyptian patients with metabolic syndrome and its association with dyslipidemia.

Zinc finger protein 1 (ZPR1), encoded by the ZNF259 gene, plays crucial roles in transcriptional regulation and cell cycle progression. Despite its known functions, its specific involvement in Metabolic Syndrome (MetS) remains debated. Genome-wide association studies have identified several genes, including ZNF259, implicated in lipid metabolism and associated with MetS. Single nucleotide polymorphisms (SNPs) in ZNF259 have been linked to altered lipid metabolism during the development of MetS. This study aims to investigate the association between MetS in Egyptian patients and three specific ZNF259 SNPs: rs964184, rs2075294, and rs2075290. The objective is to explore how these SNPs correlate with MetS development, other health outcomes, and their interaction with dyslipidemia biomarkers. 200 Egyptian participants were enrolled, and divided into two groups: 100 patients diagnosed with dyslipidemia and 100 healthy controls. The study involved comprehensive assessments, including lipid profile analysis, anthropometric measurements, and genotyping of rs964184, rs2075290, and rs2075294 in the ZNF259 gene using Real-Time Polymerase Chain Reaction (PCR). The findings indicate that rs964184 SNP correlates significantly with elevated plasma triacylglycerol (TG) levels, while rs2075290 and rs2075294 are associated with higher total serum cholesterol (TC) and TG levels. Among these SNPs, rs2075294 showed the highest predictive value (area under the curve of 0.748), followed by rs2075290 (0.738), and rs964184 (0.583), suggesting rs2075294 as the most influential SNP in MetS prediction. This study underscores the predictive role of ZNF259 SNPs in MetS risk among Egyptians. Future research should further explore the implications of ZNF259 in MetS pathogenesis and its potential as a biomarker for personalized health interventions.

The role of bound polyphenols in the anti-obesity effects of defatted rice bran insoluble dietary fiber: An insight from multi-omics

Considering the high abundance of bound polyphenols (BP) in whole grain dietary fiber (DF), this study utilized multi-omics approach to evaluate the impact of BP of defatted rice bran insoluble DF (RIDF) in modulating obesity. Mice on high-fat diet were gavage-administered RIDF, BP-removed or formulated RIDF. The results indicated that DF significantly reduced serum total cholesterol, triglycerides, high-density and low-density lipoprotein cholesterol levels. Moreover, hepatic lipid accumulation and damage induced by high-fat diet were significantly ameliorated with DF intervention. The presence of BP increased the abundance of beneficial bacteria g_Akkermansia and g_Butyricicocus, as well as the expression of butyric acid/propionic acid. Furthermore, the expression of hepatic lipids and lipid-like molecules was significantly decreased under the combined intervention of BP and DF, and this was accompanied by alterations in genes related to lipid, sterol, and cholesterol metabolic biological processes. These findings suggest that BP contribute to the anti-obesity effects of DF.

Improvement in Testosterone Production by Acorus gramineus for the Alleviation of Andropause Symptoms.

Acorus gramineus has a number of beneficial effects, including protective effects against age-related disorders. In this study, the effects of A. gramineus on testosterone production and andropause symptoms were evaluated. We first treated TM3 mouse Leydig cells, responsible for testosterone production, with A. gramineus aqueous extract at different concentrations. In TM3 cells, the testosterone concentration increased in a concentration-dependent manner compared with those in the control. In addition, at 400 μg/mL extract, the mRNA expression level of the steroidogenic enzyme CYP11A1 was increased. Subsequently, 23-week-old Sprague-Dawley (SD) rats exhibiting an age-related reduction in serum testosterone (approximately 80% lower than that in 7-week-old SD rats) were administered A. gramineus aqueous extract for 8 weeks. Serum total testosterone and free testosterone levels were higher and serum estradiol, prostate-specific antigen levels, and total cholesterol levels were lower in the AG50 group (A. gramineus aqueous extract 50 mg/kg of body weight/day) than in the OLD (control group). The AG50 group also showed significant elevations in sperm count, grip strength, and mRNA expression of StAR, CYP11A1, 17β-HSD, and CYP17A1 compared with those in the OLD group. In conclusion, A. gramineus aqueous extract facilitated steroidogenesis in Leydig cells, elevated testosterone levels, lowered serum estradiol and total cholesterol levels, and increased muscle strength and sperm count, thus alleviating the symptoms of andropause. These findings suggest that A. gramineus aqueous extract is a potentially effective therapeutic agent against various symptoms associated with andropause.

Effects of oyster mushroom (Pleurotus ostreatus) stem residue supplementation on growth performance, meat quality and health status of broilers

Oyster mushroom stem residue, a by-product with medicinal and nutritive values, might be a prospective feed supplement in poultry nutrition. The study focused on evaluating the impact of oyster mushroom (Pleurotus ostreatus) stem residue (OMSR) powder supplementation on growth performance, carcass traits, meat quality, blood characteristics, and the cecal bacterial count in Arbor Acres broilers raised 35 d. A total of 144 day-old chicks, with an average weight of 40.27± 2.45 g, were divided into 3 groups: control (received a standard basal diet), antibiotic (basal diet + 75 mg/kg chlortetracycline), and OMSR (fed a basal diet with 300 mg/kg OMSR), where each group comprises 8 replications of 6 chicks. Supplementation of 300 mg/kg of OMSR powder in the broiler diet significantly (P < 0.05) enhanced the average daily gain (ADG) and final body weight as opposed to the control and antibiotic treatments, though the average daily feed intake was not influenced by OMSR supplementation during the whole experimental period. However, in comparison to the control and antibiotic groups, OMSR significantly reduced the postmortem breast meat drip loss percentage (P < 0.05) at 24 hours and on the seventh d. Furthermore, the OMSR group reported significantly elevated levels of Hb and RBC counts (P < 0.05), and decreased levels of serum triglyceride (TG) and total cholesterol (TC) concentrations (P < 0.05) on d 35 in comparison to broilers in the control and antibiotic groups. Additionally, the OMSR group exhibited an improved Heterophil/Lymphocytes (H/L) ratio (P < 0.05) relative to the broilers of the control and antibiotic groups. In contrast, the inclusion of OMSR in the broiler diet did not significantly (P > 0.05) influence other serum biochemical and hematological values tested. Broilers in OMSR group had reduced number (P < 0.05) of E. coli and Salmonella spp., but higher presence of Lactobacillus spp. (P < 0.05) in contrast to the control broilers. To summarize, the study's findings revealed that 300 mg of OMSR powder supplementation per kg of basal diet could be act as a natural growth promoter, and confer favorable effects on health and meat quality of broilers.

Effect of the Combined Treatment of Taoren Chengqi Decoction with Laser Photocoagulation on Diabetic Retinopathy

This study investigates the therapeutic effect of the combined treatment of Taoren Chengqi decoction with laser photocoagulation on DR. In animal experiments, A total of 18 rats were used and randomly divided into blank groups, model groups, and treatment groups. The rats in the model group and treatment group were intraperitoneally injected with 60 mg/kg streptozotocin. Moreover, the TCT group was gavaged with Tao-ren Cheng-qi decoction, while the other groups received an equivalent volume of normal saline once daily for 8 weeks. Fasting blood glucose (FBG) and serum interleukin (IL)-6 and IL-1β were determined. In the clinical trial, a total of 80 patients with DR were divided into a laser group (treated with laser photocoagulation) and a combination group (treated with laser photocoagulation+Taoren Chengqi decoction). The central macular thickness (CMT), best-corrected visual acuity (BCVA), and serum levels of high-density lipoprotein cholesterol, low-density-lipoprotein cholesterol, total cholesterol, triglycerides, glycated hemoglobin, and hypoxia-inducible factor 1α were measured in the patients. In animal experiments, we observe that Tao-ren Cheng-qi decoction can effectively reduce the levels of FBG, IL-6, and IL-1β in rats models with DR. Clinical studies revealed that the combination of Taoren Chengqi decoction with laser photocoagulation reduced the levels of blood glucose and lipid-related indices, and improved the inflammatory state, BCVA, and CMT. Therefore, this study suggests that the combined treatment of laser surgery and Taoren Chengqi decoction can be considered an optimal therapeutic approach for patients with DR.

Mechanism of astragaloside Ⅳ modulation of Nrf2/HO-1/GPX4 pathway to inhibit ferroptosis and ameliorate atherosclerosis in ApoE~(-/-) mice

The intervention effect of astragaloside Ⅳ(AS-Ⅳ) on atherosclerosis in apolipoprotein E gene knockout(ApoE)~(-/-) mice was observed based on the nuclear factor erythroid-2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)/glutathione peroxidase 4(GPX4) signaling pathway to explore the potential mechanism of AS-Ⅳ in improving ferroptosis in atherosclerotic mice. This study established an atherosclerosis mouse model by feeding them a high-fat diet. After modeling for 8 weeks, ApoE~(-/-) mice were randomly divided into the model group, AS-Ⅳ group, AS-Ⅳ+Nrf2 inhibitor(ML385) group, and ferrostatin-1(Fer-1) group. Additionally, a blank control group was also established. Corresponding drugs were administered via intraperitoneal injection, with the control group receiving an equivalent amount of normal saline injection as the model group. After the experiment, serum biochemical levels were measured using an automatic blood lipid analyzer, hematoxylin-eosin(HE) staining was used to observe morphological changes in aortic sinus tissues, colorimetric methods were used to detect levels of ferrous ion(Fe~(2+)), malondialdehyde(MDA), glutathione(GSH), and superoxide dismutase(SOD) in mouse serum, immunofluorescence was used to observe the expressions of ferritin heavy chain 1(FTH1) and ferritin light chain(FTL) proteins in the aortic sinus of mice, Western blot was used to detect the protein levels of Nrf2, HO-1, and GPX4 in mouse aortic tissues, and transmission electron microscopy was used to observe ultrastructural changes in aortic tissues. RESULTS:: showed that compared to the control group, the model group of mice had significantly increased calcification and plaque deposition areas in the aortic sinus, increased mitochondrial membrane density, decreased or disappeared mitochondrial cristae, elevated levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), Fe~(2+), and MDA, decreased levels of high-density lipoprotein cholesterol(HDL-C), SOD, and GSH, and significant inhibition of Nrf2, HO-1, GPX4 proteins, as well as iron storage proteins FTH1 and FTL expressions in the aorta. Compared to the model group, AS-Ⅳ treatment resulted in decreased serum TC, TG, LDL-C, Fe~(2+), and MDA levels, increased HDL-C, SOD, and GSH levels, increased expressions of Nrf2, HO-1, and GPX4 proteins, and iron storage proteins FTH1 and FTL, and significant improvement in aortic tissue morphology. Compared to the AS-Ⅳ group, the Nrf2 inhibitor ML385 could reverse the therapeutic effect of AS-Ⅳ on atherosclerosis mice. These findings suggest that AS-Ⅳ can inhibit ferroptosis and improve atherosclerosis in ApoE~(-/-) mice, and its mechanism of action may be related to the regulation of the Nrf2/HO-1/GPX4 signaling pathway.

Effects of atypical antipsychotics on serum asprosin level and other metabolic parameters in patients with schizophrenia

AbstractBackgroundIn this cross‐sectional study, we compared fasting serum asprosin levels and metabolic parameters between patients receiving one of three atypical antipsychotics (olanzapine, risperidone, or aripiprazole) and healthy subjects.MethodsThe study population included 62 adult outpatients with schizophrenia and 22 healthy controls, matched for age and gender. Patients were in remission and had been on stable monotherapy with one of these atypical antipsychotics for over 6 months. Body Mass Index (BMI) and fasting serum levels of asprosin, glucose, HA1c, insulin, and lipid profile were compared across the investigated groups. Additionally, the number of participants meeting the insulin resistance criterion, defined as homeostasis model assessment for insulin resistance (HOMA‐IR) &gt;2.5, as well as the number of participants with elevated BMI levels (men &gt;27 kg/m2, women &gt;25 kg/m2) were compared among the groups.ResultsWe observed statistically significant differences in BMI and fasting serum levels of glucose, HA1c, insulin, triglyceride (TG), high‐density lipoprotein cholesterol, and asprosin among patients receiving olanzapine or risperidone, as compared to those receiving aripiprazole and healthy subjects. Patients on aripiprazole exhibited values comparable to healthy subjects, whereas those on risperidone or olanzapine showed significantly higher values, with the highest observed in the olanzapine group. Additionally, the prevalence of participants meeting the insulin resistance criterion and those with elevated BMI was also greater in individuals receiving olanzapine or risperidone compared to those on aripiprazole and healthy subjects. Serum asprosin levels showed a significant positive correlation with BMI and several metabolic parameters, including HbA1c, fasting insulin, HOMA‐IR, and TG. No significant differences were observed among the investigated groups in terms of serum levels of total cholesterol and low‐density lipoprotein cholesterol.ConclusionsOur cross‐sectional study highlights the association between elevated asprosin levels, weight gain, and metabolic disorders in patients treated with olanzapine and risperidone. Given the bidirectional nature of the relationship between serum asprosin levels and these metabolic disturbances, further research is warranted to elucidate potential causative pathways.

Effect of hydroxy-α-sanshool on lipid metabolism in liver and hepatocytes based on AMPK signaling pathway

BackgroundWith the increasing awareness of the safety of traditional Chinese medicine and food, as well as in-depth studies on the pharmacological activity and toxicity of Zanthoxylum armatum DC. (ZADC), it has been found that ZADC is hepatotoxic. However, the toxic substance basis and mechanism of action have not been fully elucidated. Hydroxy-α-sanshool (HAS) belongs to an amide compound in the fruits of ZADC, which may be hepatotoxic. However, the specific effects of HAS, including liver toxicity, are unclear. PurposeThe objectives of this research was to determine how HAS affects hepatic lipid metabolism, identify the mechanism underlying the accumulation of liver lipids by HAS, and offer assurances on the safe administration of HAS. MethodsAn in vivo experiment was performed by gavaging C57 BL/6 J mice with various dosages of HAS (5, 10, and 20 mg/kg). Biochemical indexes were measured, and histological analysis was performed to evaluate HAS hepatotoxicity. Hepatic lipid levels were determined using lipid indices and oil red O (ORO) staining. Intracellular lipid content were determined by biochemical analyses and ORO staining after treating HepG2 cells with different concentrations of HAS in vitro. Mitochondrial membrane potential, respiratory chain complex enzymes, and ATP levels were assessed by fluorescence labeling of mitochondria. The levels of proteins involved in lipogenesis and catabolism were determined using Western blotting. ResultsMice in the HAS group had elevated alanine and aspartate aminotransferase blood levels as well as increased liver index compared with the controls. The pathological findings showed hepatocellular necrosis. Serum and liver levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol levels were increased, whereas high-density lipoprotein cholesterol levels decreased. The ORO staining findings demonstrated elevated liver lipid levels. In vitro experiments demonstrated a notable elevation in triglyceride and total cholesterol levels in the HAS group. ATP, respiratory chain complex enzyme gene expression, mitochondrial membrane potential, and mitochondrial number were reduced in the HAS group. The levels of lipid synthesis-associated proteins (ACC, FASN, and SREBP-1c) were increased, and lipid catabolism-associated protein levels (PPARα and CPT1) and the p-AMPK/AMPK ratio were decreased in vivo and in vitro. ConclusionHAS has hepatotoxic effects, which can induce fatty acid synthesis and mitochondrial function damage by inhibiting the AMPK signaling pathway, resulting in aberrant lipid increases.

Oxford Nanopore Technologies (ONT) Full-length Transcriptomics Shows Electroacupuncture ameliorates Lipid Metabolic Disorder through Suppressing Hepatic Pdia3/Perk/Qrich1 Expression in Rats.

The incidence of dyslipidemia increases after menopause. Electroacupuncture (EA) has been recommended for menopause-related disease. However, the positive effect on lipid metabolism disorders is still unclear. To investigate the underlying mechanism of EA treatment on lipid metabolism disorders through ONT full-length transcriptome sequencing Methods: Adult female SD rats were randomly divided into Ctrl, sham operation+high-fat feed(Sham+HFD), Ovariectomized+high-fat feed (OVX+HFD), Ovariectomized+high-fat feed + Atorvastatin (OVX+HFD+ATO) and OVX+HFD+EA groups. Periovarian adipose tissue around the bilateral ovaries of rats in the Sham+HFD group was resected. Rats in the OVX+HFD, OVX+HFD+ATO and OVX+HFD+EA groups were subjected to bilateral oophorectomy to prepare the ovariectomized rat model. Treatment was applied to rats in the OVX+HFD+EA group. ST36, PC6, SP6, BL18 and ST40 were the selected acupoints. Daily food intake and body weights of rats were recorded. The samples were collected 30 days after treatment. The serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein (HDL-C) were detected to assess the improvement of lipid metabolism disorders. HE and oil red O staining were used to stain the liver tissues. Total RNA was extracted from liver tissues, and its transcriptional changes were determined by high-throughput sequencing. Additionally, RT&Aacute;qPCR and immunofluorescence staining were used to verify the crucial signal pathway screened by the ONT full&Aacute;length transcriptome sequencing. EA treatment resulted in a lowered weight of perirenal fat and liver and a significant improvement in the color of the liver. In addition, EA could improve the lipid profile and hepatic steatosis in OVX+HFD rats. According to full&Aacute;length transcriptome sequencing, 2292 genes showed differential expression in the OVX+HFD group; of these, 1121 were upregulated and 1171 down-regulated. 609 DEGs were found in the OVX+HFD+EA group compared to the OVX+HFD group; 235 up-regulated and 374 down-regulated. We also found that 77 genes are significantly upregulated after EA intervention through Venn map analysis (including Agtr1a, Pdia3, etc.), which may be the targeted genes for EA treatment of lipid metabolism disorders. Finally, we verified the expression of Pdia3, Perk and Qrich1 levels in liver tissues. HFD feeding could increase the expression of Pdia3 and its downstream signal pathways molecular Perk and Qrich1. But these effects were reversed by EA treatment, the results demonstrated that the expression of pdia3, Perk, as well as Qrich1 of OVX+HFD rats had a decreasing trend after EA treatment. EA could ameliorate lipid metabolic disorder in OVX+HFD rats. The Pdia3/Perk/Qrich1 signal pathway may play crucial roles in the improvement of lipid metabolism disorder of OVX+HFD rats after EA treatment.
