Assessment of anti-desmoglein antibodies levels and other laboratory indexes as objective comprehensive indicators of patients with pemphigus vulgaris of different severity: a single-center retrospective study.

The aim of this study is to assess the utility of anti-desmoglein (Dsg) antibodies levels, hematological biomarkers levels, the albumin to globulin (A/G) ratio, blood lipids levels, and lymphocyte subpopulation percentages as objective laboratory indicators of disease severity of pemphigus vulgaris (PV). A retrospective study of 187 PV patients with 256 medical records between January 2013 and December 2020. PV patients were divided into three groups by disease severity according to the pemphigus disease area index (PDAI) score: mild (0-8), moderate (9-24), and severe (≥ 25). The levels of anti-Dsg antibodies, hematological biomarkers, A/G ratio, blood lipids, and the percentage of lymphocyte subpopulations were measured. We assessed the correlations of quantitative variables by Pearson correlation (r). Multivariable linear regression was used to identify the variables associated with the disease severity of PV (PDAI score). The results show that the levels of Dsg1 (r = 0.294, P < 0.001) and Dsg3 (r = 0.206, P = 0.011), monocyte count (r = 0.210, P = 0.001), neutrophil-to-lymphocyte ratio (NLR) (r = 0.123, P = 0.049), and platelet-to-lymphocyte ratio (PLR) (r = 0.170, P = 0.006) were positively correlated with the PDAI score. However, the A/G ratio (r = -0.399, P < 0.001), and the levels of total serum cholesterol (r = -0.140, P = 0.026) and HDL (r = -0.143, P = 0.023) were negatively correlated with the PDAI score. Multiple linear regression showed that the factors associated with the PDAI score were higher level of anti-Dsg1 antibody (P = 0.001), a higher NLR (P = 0.005), and a lower A/G ratio (P < 0.001). The linear regression equation was Y(PDAI) = 32.798 + 0.058X(Dsg1) + 0.846 X(NLR)-16.472 X(A/G) (R2 = 0.586). Therefore, high levels of anti-Dsg1 antibody and NLR combined with a low A/G ratio could explain the PDAI score. These findings might provide a more comprehensive and objective evaluation system for reflecting the disease severity of PV based on laboratory indicators.

Protective Effects of Gallic Acid and Curcumin on Serum Levels of Hepatic Transaminases, Blood Plasma Parameters and Pituitary-testicular Hormones in Rats Treated Nickel Nanoparticles

Nickel nanoparticles (NiNPs) have toxic effects on body cells due to the production of free radicals. The purpose of this research was to investigate the protective effects of Gallic acid (GA) and Curcumin (Cur) on hepatic transaminases, blood plasma parameters and pituitary-testicular hormones levels in NiNPs-treated rats. Seventy adult male Wistar rats were divided in 7 groups of 10 including control, Ni50 mg/kg, Ni50+GA150 mg/kg, Ni50+GA300 mg/kg, Ni50+Cur150 mg/kg, Ni50+Cur300 mg/kg and Ni50+GA300+CUR300 mg/kg. NiNPs, GA and Cur were administered orally by oral gavage for 28 days. At the last phase of the study, the samples of blood were taken directly from heart and serum levels of hepatic transaminases (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), blood plasma parameters (Glucose, total protein (TP), bilirubin (Bil), albumin (Alb), creatinine (Cr), Blood urea nitrogen (BUN), triglyceride, cholesterol, HDL, LDL and alkaline phosphatase (ALP)) and pituitary-testicular hormones (FSH, LH, testosterone and dihydrotestosterone) were assessed. NiNPs administration increased serum levels of glucose, ALT, ALP, AST, Bil, BUN, Cr, triglyceride, cholesterol and LDL compared to the control group (p0.05) and in contrast, it decreased serum levels of FSH, LH, testosterone, dihydrotestosterone, Alb, TP and HDL (p0.05). However, co-administration of GA and Cur at doses of 300 ml/kg in NiNPs -treated rats improved all blood plasma parameters compared to the control group (p0.05). The findings of this study suggest that co-administration of GA and Cur at a dose of 300 mg/kg can reduce and improve the damaging effects of NiNPs on blood plasma parameters, hepatic transaminases and pituitary-testicular hormones in adult rats.

Effect of Zinc Supplementation on some Biochemical and Hematological Parameters in Alloxan Induced Diabetic Rats

Background &amp; Objective: This study aims to evaluate the effects of zinc sulfate on blood biochemical and hematological parameters in healthy control and alloxan-induced diabetic rats. &#x0D; Materials &amp; Methods: Experimentally, 40 rats were used in four equal groups, including healthy control, healthy feed with zinc sulfate, diabetic control, and zinc sulfate. The alloxan 120 mg/kg with blood sugar over 140-250 mg / dL was intraperitoneally injected to induce diabetes mellitus. In addition, the value of 0.6 g / L zinc sulfate dissolved in tap water was used for three months to be drunk by the treated group. All animals were killed, and blood and pancreas samples were collected for necessary tests. Serum levels of alpha-amylase, total cholesterol, triglycerides, LDL, HDL, hemoglobin, and hematocrit were measured. Statistical data were analyzed based on the analysis of variance using SPSS software.&#x0D; Results: Our data showed that in the diabetic control group, serum levels of total cholesterol, triglyceride, LDL increased significantly and hemoglobin, hematocrit, and HDL decreased significantly compared to the healthy control (P&lt; 0.05). Zinc sulfate consumption in these groups reduces total cholesterol, triglyceride, LDL and increases hemoglobin and hematocrit compared to the control groups. Microscopic examination of the pancreas showed that in the diabetic control group, the percentage of Beta cells was reduced compared to the other groups.&#x0D; Conclusion: Our findings reveal that dietary zinc sulfate not only exerts no damage to bodies but also zinc sulfate as food supplement seems to have beneficial effects on biochemical and hematological parameters in diabetic and healthy animals.

Coriander Oil Reverses Dexamethasone-Induced Insulin Resistance in Rats.

In the present study, we aimed to investigate the effect of coriander oil on dexamethasone-induced insulin resistance in rats and characterize its chemical composition using gas chromatography-mass spectrometry (GC-MS). Rats were divided into five groups (n = 6): Normal control, insulin resistance (IR) control, IR + metformin (50 mg/kg/day, PO, Per Oral), IR + coriander oil low dose (0.5 mL/kg, PO), and IR + coriander oil high dose (1 mL/kg, PO). IR groups were injected with a dose of 10 mg/kg dexamethasone subcutaneously for four consecutive days. All groups received either vehicle or drugs daily for four days. Animal weights and pancreatic weights were measured, and oral glucose tolerance test was performed at the end of study. Fasting glucose, triglycerides (TG), total cholesterol (TC), HDL and insulin levels in serum, MDA, and GSH levels in pancreatic tissue were measured and HOMA-IR was calculated. Immunoexpression of apoptosis markers BAX, and BCL2 was measured in pancreatic tissues and BAX/BCL2 ratio was calculated. Histopathological examination of pancreatic tissues was also performed. Pancreatic weight, serum HDL, pancreatic GSH, and BCL2 were decreased while serum glucose, insulin, TG, TC levels, AUC of OGGT, HOMA-IR, pancreatic MDA, BAX, and BAX/BCL2 ratio were increased in IR rats. Histopathological examination showed congestion, vacuolation and hemorrhage in pancreatic islets. These changes were reversed by metformin and the high dose of coriander oil treatments. The obtained activities could be attributed to the presence of 21 volatile compounds, identified by GC-MS. Our study indicates that coriander oil can be used as an adjuvant antihyperglycemic agent in type 2 diabetes. Further experiments are needed to determine the therapeutic dose and the treatment time.

Effect of a Ketogenic Diet on Body Weight and Lipid Profile

This review article aimed to study the effects of a ketogenic diet on obesity-related measures, and lipid profiles. Total 22 articles were included in the review. Anthropometric measures included in the review were total body mass (Wt), fat mass (FM), body mass index (BMI), and waist circumference (WC). The lipid profile included in this review was serum cholesterol level, serum HDL, serum LDL, and serum triglycerides (TAG). The shortest intervention in these studies lasted for 4 days, and the longest intervention lasted for 12 months. There was a significant Wt loss in all studies. A significant reduction in BMI, FM, and WC was also observed in many studies. In most studies, variable effects on lipid profile were observed. Serum TC level fell in 10 studies, and serum TAG levels decreased in 13 studies, but this reduction was statistically insignificant in most studies. Serum LDL level fell in 10 studies and increased in 3 studies, and serum HDL levels fell in 7 studies and increased in 6 studies, but these changes were also not statistically significant in most studies. This review article found beneficial effects of ketogenic diet weight loss and lipid profile, but the studies in this review included the dietary intervention of a period≤12 months. Studies for extended periods (at least ≥2 years) should be done to observe the long-term effects of a ketogenic diet.

The association between elevated lipid profile and liver enzymes: a study on Bangladeshi adults

Dyslipidemia, a major contributor to cardiovascular diseases, is rapidly increasing in Asian countries including Bangladesh. In addition to the cardiovascular system, abnormal lipid levels are also known to cause complications in renal and hepatic systems. The data regarding dyslipidemia and its relationship with liver enzymes are scarce for the Bangladeshi population. Therefore, this study was conducted to estimate the prevalence of dyslipidemia and determine the relationship between lipid profile and liver enzymes in Bangladeshi adults. A total of 405 participants (318 males and 87 females) were enrolled in the study. Serum levels of TG, TC, LDL, HDL and liver enzymes including ALT, AST, GGT and ALP were analyzed using standard methods. Dyslipidemia and liver function tests abnormalities were defined according to the international standard guidelines. The association between elevated lipid profile markers and liver enzyme abnormalities was assessed by logistic regression analysis. Overall, the prevalence of elevated TG, TC, LDL and low HDL were 30.9%, 23.7%, 26.2% and 78.8%, respectively. On the other hand, the prevalence of elevated liver enzymes ALT, AST, GGT and ALP were 18.8%, 21.6%, 12.9% and 21.9%, respectively. Dyslipidemia and liver enzyme abnormalities were higher in diabetic and hypertensive participants than in the healthy participants. About 61% of participants with dyslipidemia had at least one or more elevated liver enzymes. In regression analysis, an independent association was observed between serum GGT and all lipid components. In conclusion, a high prevalence of dyslipidemia and liver enzyme abnormalities were observed among the study participants. Of the four liver enzymes, the serum levels of GGT showed an independent association with all lipid components. Moreover, this study indicates that subjects with dyslipidemia often have a higher chance of having liver diseases than subjects with no dyslipidemia. However, large-scale prospective studies are needed to understand the underlying mechanisms of lipid-induced hepatic dysfunction in the Bangladeshi population.

Estimation of Vitamin C and the Fructose Levels in Some Medicinal Plants and their Effects on Iron Bioavailability in Rats

Iron deficiency is considered as a common problem facing the general world population. In the current research, experiments were conducted to evaluate the effects of aqueous extracts of Acacia senegal (Gum Arabic, GA), Spinacia oleracea (spinach), Zea mays (corn), and Capsicum annuum (red chili pepper) on iron and ferritin levels in rats. Vitamin C and fructose levels were first estimated in these plants by using High-Performance Liquid Chromatography (HPLC). The results showed that the GA extract contained the highest level of fructose (853 mg.L-1), followed by red chili pepper (635 mg.L-1), corn (521 mg.L-1), and spinach (271 mg.L-1) extracts. Also, the results of vitamin C estimation showed levels of 3.376, 0.645, 0.579, and 0.347 mg/ml in the extracts of spinach, red chili pepper, corn, and GA, respectively. Next, thirty male albino rats (age 8-12 weeks, weight 120-200 g) were divided randomly into six groups, each kept in a separate polypropylene rat cage. Treatments of rats with various plant extracts were conducted following a CRD complete random design, with five replicates for each treatment. The results of lipid profile test revealed that GA treatment caused the highest reduction in the serum levels of TC, TG, LDL, VLDL, and HDL in the treated rats (76.25, 55.25,23, 15.25, and 38 mg/dl , respectively), as compared to the other plant extracts. Evidence from this study suggests that the higher serum level of fructose in the group of rats treated with all plant extracts enhances the process of ferritin formation, possibly via increasing the level of bioavailable iron.

Dietary Enteromorpha polysaccharide-Zn supplementation regulates amino acid and fatty acid metabolism by improving the antioxidant activity in chicken

BackgroundEnteromorpha prolifera (E. prolifera) polysaccharide has become a promising feed additive with a variety of physiological activities, such as anti-oxidant, anti-cancer, anti-diabetic, immunomodulatory, hypolipidemic, and cation chelating ability. However, whether Enteromorpha polysaccharide-trace element complex supplementation regulates amino acid and fatty acid metabolism in chicken is largely unknown. This study was conducted to investigate the effects of E. prolifera polysaccharide (EP)-Zn supplementation on growth performance, amino acid, and fatty acid metabolism in chicken.MethodsA total of 184 one-day-old Ross-308 broiler chickens were randomly divided into two treatment groups with 8 replicates, 12 chickens per replicate, and fed either the basal diet (control group) or basal diet plus E. prolifera polysaccharide-Zinc (400 mg EP-Zn/kg diet).ResultsDietary EP-Zn supplementation significantly increased (P < 0.05) the body weight, average daily gain, muscle antioxidant activity, serum HDL level, and reduced serum TG and LDL concentration. In addition, dietary EP-Zn supplementation could modulate ileal amino acid digestibility and upregulate the mRNA expression of amino acid transporter genes in the jejunum, ileum, breast muscle, and liver tissues (P < 0.05). Compared with the control group, breast meat from chickens fed EP-Zn had higher (P < 0.05) Pro and Asp content, and lower (P < 0.05) Val, Phe, Gly, and Cys free amino acid content. Furthermore, EP-Zn supplementation upregulated (P < 0.05) the mRNA expressions of mTOR and anti-oxidant related genes, while down-regulated protein degradation related genes in the breast muscle. Breast meat from EP-Zn supplemented group had significantly lower (P < 0.05) proportions of Σn-3 PUFA, and a higher percentage of Σn-6 PUFA and the ratio of n-6/n-3 PUFA. Besides, EP-Zn supplementation regulated lipid metabolism by inhibiting the gene expression of key enzymes involved in the fatty acid synthesis and activating genes that participated in fatty acid oxidation in the liver tissue.ConclusionsIt is concluded that EP-Zn complex supplementation regulates apparent ileal amino acid digestibility, enhances amino acid metabolism, and decreases oxidative stress-associated protein breakdown, thereby improving the growth performance. Furthermore, it promotes fatty acid oxidation and restrains fat synthesis through modulating lipid metabolism-related gene expression.Graphical abstract

Lipid reprogramming induced by the TFEB-ERR\u03b1 axis enhanced membrane fluidity to promote EC progression

BackgroundEstrogen-related receptor α (ERRα) has been reported to play a critical role in endometrial cancer (EC) progression. However, the underlying mechanism of ERRα-mediated lipid reprogramming in EC remains elusive. The transcription factor EB (TFEB)-ERRα axis induces lipid reprogramming to promote progression of EC was explored in this study.MethodsTFEB and ERRα were analyzed and validated by RNA-sequencing data from the Cancer Genome Atlas (TCGA). The TFEB-ERRα axis was assessed by dual-luciferase reporter and chromatin immunoprecipitation quantitative polymerase chain reaction (ChIP-qPCR). The mechanism was investigated using loss-of-function and gain-of-function assays in vitro. Lipidomics and proteomics were performed to identify the TFEB-ERRα-related lipid metabolism pathway. Pseudopods were observed by scanning electron microscope. Furthermore, immunohistochemistry and lipidomics were performed in clinical tissue samples to validate the ERRα-related lipids.ResultsTFEB and ERRα were highly expressed in EC patients and correlated to EC progression. ERRα is the direct target of TFEB to mediate EC lipid metabolism. TFEB-ERRα axis mainly affected glycerophospholipids (GPs) and significantly elevated the ratio of phosphatidylcholine (PC)/sphingomyelin (SM), which indicated the enhanced membrane fluidity. TFEB-ERRα axis induced the mitochondria specific phosphatidylglycerol (PG) (18:1/22:6) + H increasing. The lipid reprogramming was mainly related to mitochondrial function though combining lipidomics and proteomics. The maximum oxygen consumption rate (OCR), ATP and lipid-related genes acc, fasn, and acadm were found to be positively correlated with TFEB/ERRα. TFEB-ERRα axis enhanced generation of pseudopodia to increase the invasiveness. Mechanistically, our functional assays indicated that TFEB promoted EC cell migration in an ERRα-dependent manner via EMT signaling. Consistent with the in vitro, higher PC (18:1/18:2) + HCOO was found in EC patients, and those with higher TFEB/ERRα had deeper myometrial invasion and lower serum HDL levels. Importantly, PC (18:1/18:2) + HCOO was an independent risk factor positively related to ERRα for lymph node metastasis.ConclusionLipid reprogramming induced by the TFEB-ERRα axis increases unsaturated fatty acid (UFA)-containing PCs, PG, PC/SM and pseudopodia, which enhance membrane fluidity via EMT signaling to promote EC progression. PG (18:1/22:6) + H induced by TFEB-ERRα axis was involved in tumorigenesis and PC (18:1/18:2) + HCOO was the ERRα-dependent lipid to mediate EC metastasis.

Association of Non-Alcoholic Fatty Liver Disease with Metabolic Syndrome: A Single Center Study

Background: NAFLD is a condition defined by excessive fat accumulation in the form of triglycerides (steatosis) in the liver (&gt; 5% of hepatocytes histologically). Non-alcoholic fatty liver disease is increasingly being recognized as a major cause of liver-related morbidity and mortality among 15-40% of the general population. Aim of the study: To evaluate the clinical profile of patients with non-alcoholic fatty liver disease and its association with metabolic syndrome.Methods:The present cross-sectional, retro-spective study was conducted as outdoor patient basis in the Department of Medicine, Jashore medical college hospital &amp; a private diagnostic centre, Jashore.. A total of 74 cases were included for the study. All patients in the study underwent routine investigations including complete blood counts, blood sugar, liver function tests, HBsAg, anti-HCV, lipid profile andUSG of whole abdomen. The data was collected during OPD treatment and was recorded in predesigned and pretested proforma and analyzed.Results:Mean age of the patient was 53.70±7.22 years. On physical examination findings showed the mean BMI was 27.6±4.39 kg/m2, mean waist circumference was 74.22±7.44 cm. Mean diastolic blood pressure (mm Hg) was 92.87±6.25 and mean systolic blood pressure (mm Hg) 132.0±18.17. Maximum 52% patients had triglycerides &gt;150 mg/dl while low serum HDL level was seen in 37% patients and increased waist circumference was found in 32% patients. Altered ALT ≥41 IU was observed in 10 (62.50%) of Grade II of patients with NAFLD with metabolic syndrome. Central obesity was observed in 12 (75.00%) of Grade II patients with NAFLD with metabolic syndrome. While 14 (87.50%) Grade II of patients with NAFLD with metabolic syndrome showed impaired fasting glucose (&gt;110 mg/dl). Hypertriglyceridemia (&gt;150 mg/dl) in 12 (70.58%) seen in Grade I of patients with NAFLD without metabolic syndrome.Conclusion:Higher prevalence of all the components of metabolic syndrome in cases of NAFLD was observed. It can be concluded that symptoms and signs of NAFLD are non-specific and occur later in the course of the disease hence the physician should have a high index of suspicion in order to detect NAFLD early in the course of the disease.

Dyslipidemia and Vitamin D Status in Diabetic Patients

Background: Dyslipidemia is one of the most common metabolic syndrome among diabetic patients due to several factors include insulin insufficiency, resistance, and central obesity. Furthermore both vitamin D deficiency and diabetes are most public health worldwide problems. Therefore the aim of the present work to study the dyslipidemia and vitamin D status in diabetes patients and also to study the relation between vitamin D status and lipid profile in diabetic patients. Methods: A Cross sectional study conducted on randomly selected diabetic patients whether have vitamin D deficiency with dyslipidemia, vitamin D deficiency with no dyslipidemia or dyslipidemia with no vitamin D deficiency. A total sample 165 patients enrolled in the study with serum lipid profile, vitamin D and glycemic control measured at beginning and end of the study. The data analysis was done through Chi-square or T test at α&lt; 0.05. Result: The data collected on 165 patients revealed that, patients aged 41-60 years were most common, and female gender was twice as male. This study include both types of diabetes with vitamin D deficiency and dyslipidemia or vitamin D deficiency with no dyslipidemia or dyslipidemia with not vitamin D deficiency as control. Therefore, the result of this work confirmed that vitamin D deficiency significant implicated in elevated serum levels of TG, TC, LDL, VLDL, FPG and HbA1C (P&lt; 0.05). However, vitamin D deficiency has linked to slight increased serum HDL levels. In compared to man, vitamin D deficiency linked significantly to dyslipidemia and abnormal high levels blood glucose and HbA1C par in women. Conclusion: The present study revealed that, vitamin D deficiency associated negatively with serum levels of TC, TG, VLDL, LDL, FPG and HbA1C whereas the deficiency of vitamin D linked to elevated HDL levels. In gender distribution lower vitamin D values associated with elevated serum FPG, HbA1C, lipid profile with exception HDL in women. The data of this study suggested that, diabetic patients with dyslipidemia may improve their lipid profile and glucose hemostasis through vitamin D supplementation

Trifolium pratense ethanolic extract alters the gut microbiota composition and regulates serum lipid profile in the ovariectomized rats

BackgroundTrifolium pratense (red clover) ethanolic extract (TPEE) has been used as a popular over-the-counter remedy for the management of menopausal symptoms. Prolonged consumption of herbal extract has been shown to regulate the composition of gut microbiota. This study was designed to elucidate the influence of TPEE on the gut microbiota composition in the ovariectomized (OVX) rats.MethodsOVX rats were treated with TPEE at 125, 250, 500 mg/kg/day, or controls (pomegranate extract, 500 mg/kg/day; estradiol, 25 μg/kg/day) for 12 weeks. Gut microbiota analysis was conducted by extracting the microbial DNA from fecal samples and microbiome taxonomic profiling was carried out by using next-generation sequencing. The levels of serum biomarkers were analyzed using enzyme-linked immunosorbent assay (ELISA) kit. The prediction of functional biomarker of microbiota was performed using PICRUSt to investigate the potential pathways associated with gut health and serum lipid profile regulation. To study the correlation between gut microbiota composition and serum lipid levels, Spearman’s correlation coefficients were defined and analyzed. Additionally, gas chromatography–mass spectrometry analysis was conducted to uncover additional physiologically active ingredients.ResultsTPEE-treated OVX rats showed significant reduction in serum triglycerides (TG), total cholesterols (TCHOL), and LDL/VLDL levels but increase in HDL level. The alteration in the pathways involve in metabolism was the most common among the other KEGG categories. Particularly, TPEE also significantly reduced the relative abundance of sequences read associated with inflammatory bowel disease (IBD) and the peroxisome proliferator-activated receptor (PPAR) signalling pathway. TPEE intervention was seen to reduce the Firmicutes to Bacteroidetes (F/B) ratio in the OVX rats, denoting a reduction in microbial dysbiosis in the OVX rats. Correlation analysis at the phylum level revealed that Bacteriodetes and Proteobacteria were strongly correlated with serum TG, TCHOL and HDL levels. At the species level, Bifidobacterium pseudolongum group was seen to positively correlate with serum HDL level and negatively correlated with serum AST, ALT, LDL/VLDL, TCHOL, and TG levels.ConclusionsTPEE treatment showed therapeutic benefits by improving the intestinal microbiota composition which strongly correlated with the serum lipid and cholesterol levels in the OVX rats.

The paraoxonase 1 activity and lipid levels in umbilical cord blood and maternal venous blood, and their relations according to birth weight

Objectives: Aim of this study is to find out the clinical relevance of estimating paraoxonase activity of PON1 enzyme, triglyceride (TG), total cholesterol, HDL, and LDL levels in maternal serum and umbilical cord blood according to birth weight. Methods: Venous blood samples were taken from mothers just before birth. Babies were divided into four groups: normal-weight babies, premature babies, low birth weight babies, and postmature babies. The weight of the newborns was measured and cord blood was taken. The samples were looked at HDL, LDL, total cholesterol, triglyceride levels and PON1 activities. We have investigated the paraoxonase activity of the PON1 enzyme. Enzyme activity assay was obtained spectrophotometrically measurement of p‐nitrophenol at 412 nm. Results: Maternal PON1 paraoxonase activity levels in Pre-Term show a significant decrease in cases as compared to other groups. Baby PON1 paraoxonase activity levels are also found to be significantly decreased in cases concerning the Term and Post-Term groups. There was a significant difference in all values the such as baby's weight, TG, Total cholesterol, HDL, LDL and PON1.belonging to babies (p &amp;lt; 0.05). Conclusions: Decreased paraoxonase activity in maternal serum may be considered as an additional risk factor for the development of low birth weight. It appears that PON1 activity plays an important role in infant development and affects birth weight. We think that the paraoxonase activity of the PON1 enzyme in mothers may be a marker in predicting the babies who are at risk in terms of birth weight.

TO STUDY THE SERUM LIPID PROFILE IN ISCHEMIC AND HEMORRHAGIC STROKE AMONG THE PATIENTS IN TERTIARY HEALTH CENTRE

Objectives: To assess, correlate and compare the levels of various parameters of lipid profile in patients with ischemic and hemorrhagic stroke. Methods: The study was conducted as an observational study at the Department of Medicine, People’s Hospital on 100 patients presenting with focal neurological deficit, altered sensorium, or with CT/MRI findings suggestive of stroke during the study duration of 18 months. Based upon the type of stroke, patients were categorized into two groups, i.e. ischemic stroke and hemorrhagic stroke. NCEP-ATP III guidelines were used for estimation of dyslipidemia and association of dyslipidemia was observed with type of stroke. Results: Of 100 cases, ischemic stroke was documented in 74% cases, whereas 26% of patients presented with hemorrhagic stroke. Two groups were comparable in terms of baseline characteristics (p&gt;0.05). Mean total cholesterol levels and total cholesterol and total cholesterol to HDL ratio was significantly higher in ischemic stroke as compared to hemorrhagic stroke (p&lt;0.05). However, mean serum HDL level was significantly lower in patients with ischemic stroke as compared to hemorrhagic stroke (p&lt;0.05). Total cholesterol, and total cholesterol: HDL ratio showed statistically significantly negative correlation with type of stroke and positive correlation was noted between HDL and hemorrhagic stroke. Conclusion: The prevalence of stroke is rising rapidly and the age of presentation of stroke is reducing. Ischemic stroke is the most common type of stroke whereas hemorrhagic stroke is less commonly observed in less than one-third of patients. Dyslipidemia is a significant risk factor for ischemic stroke. Raised Total cholesterol, and total cholesterol: HDL levels and lower HDL levels are independent predictors of ischemic stroke.

Evaluation of Cardiometabolic Markers in Helicobacter pylori Infection: A Case-control Study

Introduction: Helicobacter pylori (H. pylori) is a gram negative bacterium that naturally colonises the gastric epithelium and causes chronic gastritis. H. pylori infection affects gastric physiology and alters the lipid metabolism pathways. Highsensitivity CRP (hs-CRP) is a useful marker for risk assessment of future cardiovascular events. Many studies have proposed a link between cardiometabolic markers like lipid profile and hs-CRP with H. pylori infection but very limited studies are available to explain the effect of H. pylori infection on these cardiometabolic markers. Aim: To analyse the cardiometabolic markers (lipid profile, and hs-CRP) in H. pylori infection. Materials and Methods: This case-control study was conducted from November 2018 to June 2019 in the Department of Biochemistry in association with the Department of Surgery, Mysore Medical College and Research Institute, Mysore, Karnataka, India, 50 cases and 50 control subjects were enrolled. Fasting Total Cholesterol (TC), Triglycerides (TG), High Density Lipoprotein Cholesterol (HDL-C), Low Density Lipoprotein Cholesterol (LDL-C), Very Low Density Lipoprotein Cholesterol (VLDL-C), hs-CRP and atherogenic Index of Plasma (AIP) were analysed. Statistical analysis was performed using Student’s t-test. Results: The gender distribution was almost same in the two groups. The mean age in the case group was 47.34±12.08 years, while that in the control group was 46.2±14.8 years. There was an increase in TC, LDL, VLDL, and TG in cases`, but it was not statistically significant. Serum HDL level was 34.59±9.79 mg/ dL, and 41.62±10.29 mg/dL for cases and controls respectively and it was statistically significant. hs-CRP level was significantly increased in the case group (5.51±4.59 mg/L) when compared to the control (2.63±2.0 mg/L). AIP was also significantly high in the cases (0.246±0.219) than the controls (0.106±0.22). Conclusion: Significant decrease in HDL and increase in hsCRP levels in cases show evidence of dyslipidaemia and atherogenic risk. hs-CRP also showed a significant correlation with AIP. Hence, these cardiometabolic markers may have a role in identifying individuals at higher risk for cardiovascular diseases in cases.

Functional Effect of Lesser Yam Symbiotic Yoghurt on Hypercholesterolemia Wistar Rats

Synbiotic lesser yam yoghurt is fermented drink made from the mixture of cow’s milk and lesser yam extract which has functional benefits. Lesser yam yoghurt contains lactic acid bacteria, lactic acid, inulin, and soluble fiber which can improve the lipid profile of hypercholesterolemia sufferers. This study aims to determine the effect of the intake of lesser yam yoghurt on the lipid profile of hypercholesterolemia wistar rats. This study used nested randomized design with two factors, the first factor was a feeding group (0,1,2,3,4 ml/day, while the second factor was the time of blood collection (0, week 1 and week 2). The data obtained were analyzed by using ANAVA and further test DMRT (Duncan Multiple Range Test) with a level of 5%. The results showed that giving lesser yam yoghurt for 2 weeks had a significant effect on the lipid profile improvement. Rats from 4 ml of yoghurt treatment experienced a decrease in total serum cholesterol by 48.4%, triglyceride levels by 35.8% and LDL levels by 65,5% and an increase in serum HDL levels by 150.3%. So it can be concluded that the intake of synbiotik lesser yam yoghurt has functional benefits in improving the lipid profile of hypercholesterolemia rats.

The role of Nrf2/SIRT1 pathway in the hepatoprotective effect of PEITC against HFD/STZ-induced diabetic liver disease. Short title: PEITC ameliorates liver injury via Nrf2/SIRT1 pathways

Aim: We intended to assess the hepatoprotective effects of phenethyl isothiocyanate (PEITC) against oxidative liver injury induced by a high-fat diet (HFD) and streptozotocin (STZ) diabetes through the Nuclear Factor E2-Related Factor 2 (Nrf2) and Sirtuin 1 (SIRT1) pathways in rats. Materials and Methods: Thirty male Wistar Albino rats were separated into three groups: the control group, the second group (HFD+STZ) fed HFD and injected with STZ (35mg/kg b.w.), and the third group (HFD+ STZ+PEITC) fed an HFD, injected with STZ (35mg/kg b.w.), and given PEITC (40mg/kg b.w. by oral gavage). Feeding with HFD and PEITC was given for two weeks and continued one more week following STZ. Serum ALT and lipids levels, antioxidant enzyme activities, MDA, GST, SIRT1, NF-ƙβ, and Nrf2 levels were measured. Liver histological changes were detected. Results: In comparison with the control group, in the HFD+STZ group, serum HDL levels, activities of hepatic antioxidant enzymes, Nrf2 activity, levels of GST, SIRT1, and NF-ƙβ reduced and besides, serum ALT, TG, TC, LDL / VLDL, and hepatic MDA levels increased (p &lt;0.05). PEITC pre-administration led to improvement in these changes made by HFD-STZ (p &lt;0.05). Conclusion: Our data presented that PEITC ameliorated hepatic injury and serum lipid profile induced by HFD and STZ via the activation of Nrf2 and SIRT1 pathways. We can suggest that PEITC could be a possible candidate agent against liver diseases.

Pre-Clinical Evidence for the Anti-Obesity Potential of Quercetin and Curcumin Loaded Chitosan/PEG Blended PLGA Nanoparticles

This research aimed to formulate quercetin (Qu) and curcumin (CUR)-loaded PLGA NPs coated with chitosan (CS) &amp; PEG and to explore their therapeutic effect against obesity in rats. Qu and CUR nanostructures were prepared and characterized by Zetasizer and TEM. Then, the formulated nanoparticles and their free couterparts were employed for mitigation of obesity in female rats. The size of NPs was in nanometer range with an average size distribution 307.9 nm for Qu NPs and 322.5 nm for CUR NPs. The Qu NPs and CUR NPs were appeared in the TEM image containing core in which the Qu or CUR was localized and surrounded by the coat of PLGA-CS-PEG. The Qu NPs exhibited negative zeta potential at -8.5 mV, while, CUR NPs exhibited positive zeta potential at +0.916 mV. Treatment with orlistat, free Qu, Qu NPs, free CURor CUR NPs elicited significant decline in body weight, BMI and Lee index. Orlistat and CUR NPs significantly diminished liver, heart and visceral adipose tissue weights. Furthermore, the suggested treatments significantly reduced the gonadal and subcutaneous adipose tissue weights. Orlistat significantly lessened kidney and adrenal weights. All treatments significantly minimized serum Chol., TG, LDL, glucose, INS, HOMA-IR, LH, MDA, TLR4 and NF-κB levels and elevated serum HDL, E2 and TAC levels. Orlistat significantly enhanced serum IL-10 level. Conclusively, Qu and CUR nanoformulations offer anti-obesity potency through their hypolipidemic, hypoglycemic,antioxidative and anti-inflammatory effects. Both Qu and CUR NPs manifested superior effect than their free counterparts, may be because of solubility elevation as well as bioavailability of the nanoencapsulation.

Intestine-specific ablation of the Hepatocyte Nuclear Factor 4a (Hnf4a) gene in mice has minimal impact on serum lipids and ileum gene expression profile due to upregulation of its paralog Hnf4g

Ablation of the gene encoding the nuclear receptor Hepatocyte Nuclear Factor 4a (Hnf4a) in the liver strongly affects HDL concentration, structure and functionality but the role of this receptor in the intestine, the second organ contributing to serum HDL levels, has been overlooked. In the present study we show that mice with intestine-specific ablation of Hnf4a (H4IntKO) had undetectable levels of ΗΝF4A in ileum, proximal and distal colon but normal expression in liver. H4IntKO mice presented normal serum lipid levels, HDL-C and particle size (α1-α3). The expression of the major HDL biogenesis genes Apoa1, Abca1, Lcat was not affected but there was significant increase in Apoc3 as well as in Hnf4g, a paralog of Hnf4a. RNA-sequencing identified metabolic pathways significantly affected by Hnf4a ablation such as type II diabetes, glycolysis, gluconeogenesis and p53 signaling. Chromatin immunoprecipitation assays showed that HNF4G bound to various apolipoprotein gene promoters in control mice but its binding affinity was reduced in the ileum of H4IntKO mice suggesting a redundancy but also a cooperation between the two factors. In the distal colon of H4IntKO mice, where both HNF4A and HNF4G are absent and in a mouse model of DSS-induced colitis presenting decreased levels of HNF4A, most lipoprotein genes were strongly downregulated. In conclusion, Hnf4a ablation in mice does not significantly affect serum lipid levels or lipoprotein gene expression in ileum possibly due to compensatory effects by its paralog Hnf4g in this tissue.
