Abstract Obesity is often introduced as one of the metabolic disorders caused by imbalance between energy consumption and metabolisable energy intake. Experts in the field considered obesity as one of the robust risk factors for the life-style associated diseases. The present research examined interventional effects of marine chitosan (CS), swimming training (ST) and combination of CS and ST (CS+ST) in the mice fed with high fat diets (HFD). In this study, sample size was considered more than 3 in groups. Forty mice were randomly divided into 5 groups (n = 8 per group) including control group (received the standard diet), HFD group (received high fat food with 20% fat), HFD+CS group (treated with high fat food with 5% CS), HFD+ST group (treated with high fat diet and ST) and HFD+CS+ST group (treated with high fat food with 5% CS & ST). After 8 weeks the blood glucose, oxidative stress (OS), and lipid profile were measured. Results showed more efficiency of CS+ST in the control of body weight with the increased concentration of HDL-C, OS inhibition via enhancing the body antioxidant capacity in comparison to the ST or CS alone in obese mice. Moreover, lipid profile was improved in CS + ST-treated mice compared with HFD-treated mice, and OS inhibition correlated to the greater activities of the antioxidant enzyme, enhance the lipid oxidation, cholesterol and fatty acid homeostasis. The results suggested that a dietary intervention with a combined ST and CS can be a feasible supplementary for human prevention of obesity.

Hypolipidemic and hypoglycemic properties of ginger in animal models have been reported. However, information related to the mechanisms and factors involved in the metabolic effects of ginger at a hepatic level are limited. The aim of the present study was to investigate molecular factors involved in the hypoglycemic and hypolipidemic effects of a hydroethanolic ginger extract (GE) in the liver of rats fed a high-fat diet (HFD). The study was conducted in male Wistar rats divided into the following 3 groups: (i) Rats fed a standard diet (3.5% fat), the control group; (ii) rats fed an HFD (33.5% fat); and (iii) rats fed an HFD treated with GE (250 mg·kg−1·day−1) for 5 weeks (HFD+GE). Plasma levels of glucose, insulin, lipid profile, leptin, and adiponectin were measured. Liver expression of glycerol phosphate acyltransferase (GPAT), cholesterol 7 alpha-hydroxylase, peroxisome proliferator-activated receptors (PPAR), PPARα and PPARγ, glucose transporter 2 (GLUT-2), liver X receptor, sterol regulatory element-binding protein (SREBP1c), connective tissue growth factor (CTGF), and collagen I was measured. Data were analyzed using a 1-way ANOVA, followed by a Newman−Keuls test if differences were noted. The study showed that GE improved lipid profile and attenuated the increase of plasma levels of glucose, insulin, and leptin in HFD rats. This effect was associated with a higher liver expression of PPARα, PPARγ, and GLUT-2 and an enhancement of plasma adiponectin levels. Furthermore, GE reduced liver expression of GPAT, SREBP1c, CTGF, and collagen I. The results suggest that GE might be considered as an alternative therapeutic strategy in the management of overweight and hepatic and metabolic−related alterations.

High-fat diet (HFD) is a major problem causing neuronal damage. Thymoquinone (TQ) could regulate oxidative stress and the inflammatory process. Hence, the present study elucidated the significant role of TQ on oxidative stress, inflammation, as well as morphological changes in the cerebellum of rats with HFD. Rats were divided into three groups as (1) control, (2) saturated HFD for eight weeks and (3) HFD supplementation (four weeks) followed by TQ 300 mg/kg/day treated (four weeks). After treatment, blood samples were collected to measure oxidative stress markers glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), and inflammatory cytokines. Furthermore, neuronal morphological changes were also observed in the cerebellum of the rats. HFD rats show higher body weight (286.5 ± 7.4 g) as compared with the control group (224.67 ± 1.78 g). TQ treatment significantly (p < 0.05) lowered the body weight (225.83 ± 13.15 g). TQ produced a significant (p < 0.05) reduction in cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). The antioxidative enzymes significantly reduced in HFD rats (GSH, 1.46 ± 0.36 mol/L and SOD, 99.13 ± 5.41 µmol/mL) as compared with the control group (GSH, 6.25 ± 0.36 mol/L and SOD, 159.67 ± 10.67 µmol/mL). MDA was increased significantly in HFD rats (2.05 ± 0.25 nmol/L) compared to the control group (0.695 ± 0.11 nmol/L). Surprisingly, treatment with TQ could improve the level of GSH, MDA, and SOD. TQ treatment significantly (p < 0.05) reduced the inflammatory markers as compared with HFD alone. TQ treatment minimizes neuronal damage as well as reduces inflammation and improves antioxidant enzymes. TQ can be considered as a promising agent in preventing the neuronal morphological changes in the cerebellum of obese populations.

Aim: This study evaluated the combined effect of coconut water and garlic tincture on lipid and antioxidants profile of albino rats fed with high fat diet and alcohol. Study Design: This study is a non-randomized experimental study design. Place and Duration of Study: Rivers State University Chemical Pathology Laboratory, Department of Medical Laboratory Science, the study was done between 20th November, 2018-30th June 2019. Methodology: A total number of 45 Wister albino rats were used with the weight ranged from 120-200 grams. The animals were grouped into two major groups, the control Group A and the test Group B. Blood samples were collected via cardiac puncture into heparinized bottle for standard laboratory investigation of lipid profile, and Superoxide dismutase (SOD), Total antioxidant capacity (TAC) and Malondialdehide (MDA). Plasma SOD and MDA were determined using ELISA methods, TAC was determined using FRAP Colorimetric method while lipid profile were determined using enzymatic method. Results: The results revealed that, alcohol induced oxidative stress group exhibited significant differences in MDA levels amongst the groups, and no significance differences in SOD and TAC levels as compared with negative control groups. There were significant differences in the Total Cholesterol and low density lipoprotein levels, amongst the groups. However, these changes appear to improve with coconut water and garlic tincture treatment. Treatment with coconut water alone following 30% alcohol treatment, showed a significant decrease in MDA level, no significant increase in SOD and TAC. Similar observation was recorded for the garlic tincture treatment alone. Treatment with low dose of combined coconut water with garlic tincture following 30% alcohol treatment, shows significant decrease in MDA level, significant increase in SOD, no significant increase in TAC. Treatment with low and higher doses of combined coconut water with garlic tincture following HFD treatment showed similar results, no significant decrease in TG levels, a significant decrease in MDA, TC and LDL levels, a significant increase in TAC and HDL levels and no significant increase in SOD. However, no difference was observed at higher dose. Histological findings revealed changes in hepatocellular architecture, such as inflammatory cell aggregates, dilation of sinosidal space, fatty droplet after treatment with alcohol and high fat diet. However, upon garlic tincture and coconut water treatment, there was amelioration of these abnormalities. Conclusion: The mixture of coconut water and garlic tincture seem to exerted an antioxidant and antiatherogenic effect on alcohol-induced oxidative stress and HFD-induced dyslipidaemia in rats.

Obesity becomes a global epidemic nowadays. The high-fat diet is used as an alternative therapy for obesity. The optimal composition of a high-fat diet to reduce body weight is still unknown. This study aimed to determine which components of a high-fat diet can decrease body weight, visceral fat, and PPARG expression of visceral fat. This study was conducted at the Faculty of Veterinary Medicine, Universitas Airlangga, for three months by using a randomized post-test only control group design. Fifty male mice, 2-3 months old, 18-30 grams were adapted for one week given standard diet AIN93-M, then mice were divided into five groups, namely K1 (control group, 12% fat, 20% protein, 62% carbs); K2 (30% fat, 60% proteins, 0% carbs); K3 (45% fat, 45% protein, 0% carbs);  K4 (60% fat, 30% protein, 0% carbs); and K5 (75% fat, 15% protein, 0% carbs). Bodyweight was measured before and after treatment, then the visceral fat and PPARG expressions were evaluated. Statistical comparisons were performed using Statistical Package for the Social Sciences (SPSS) software. After treatment, there were forty-three mice. The body weight and visceral fat weight of the mice with a high-fat diet were decreased. The most significant changes in body weight were in K4 with -9,60 ± 3,806 grams reduction. The bodyweight of mice in K5, slightly increased than K2-K4. This could be caused by the hormesis phenomenon. PPARG expressions decreased in groups with a high-fat diet but increased in K5. The composition of a high-fat diet in group K4 was the most optimal to decrease the body weight, visceral fat, and PPARG expressions in mice

Abstract Nowadays, high-fat foods are eaten in most societies, which causes memory impairment and anxiety through the oxidative stress pathway. Sesame oil (SO) has potential antioxidant properties. Therefore, the effects of sesame oil on memory impairment and anxiety caused by a high-fat diet (HFD) in male rats were investigated. Eighty male Wistar rats were divided into eight groups (n = 10): control (standard diet; SD), the HFD, SD + SO (0.5, 1, or 2 ml/kg; once/day, gavage), and HFD + SO (0.5, 1, or 2 ml/kg; once/day, gavage) groups. All diets were given to the animals for three months. Finally, behavioral and oxidative stress parameters were measured. The step-through latency of retention test in SD + SO (0.5 or 1 ml/kg) groups increased more than the control group. Also, the Barnes test on training days revealed that the latency time to find the target hole increased in the HFD group compared with the control group. Moreover, the time spent on the open arms in the SD + SO (0.5 ml/kg) group improved remarkably than the control group. Total oxidant (TOS) level in the HFD + SO (0.5, 1, and 2 ml/kg) groups was lower than the HFD group. The level of total antioxidant capacity (TAC) in the SD + SO (2 ml/kg) group was higher than the SD + SO (0.5 ml/kg) group and the amount of thiol in the HFD group decreased compared with the control group. These findings suggest that the positive effects of SO on memory and anxiety are probably due to its antioxidant properties and the elimination of free radicals.

This study investigated the effects of berberine on amelioration of hyperglycemia and hyperlipidemia and the mechanism involved in high glucose and high fat diet-induced diabetic hamsters. Golden hamsters fed with high glucose and high fat diet were medicated with metformin, simvastatin, and low or high dose of berberine (50 and 100 mg·kg−1) for 6 weeks. The results showed that the body weights were significantly lower in berberine-treated groups than control group. Histological analyses revealed that the treatment of berberine inhibited hepatic fat accumulation. Berberine significantly reduced plasma total cholesterol, triglyceride, free fatty acid, low density lipoprotein cholesterol, malondialdehyde, thiobarbituric acid-reactive substance, and 8-isoprostane level but significantly increased plasma superoxide dismutase activity. Glucose and insulin levels were significantly reduced in metformin and berberine-treated groups. Glucose tolerance tests documented that berberine-treated mice were more glucose tolerant. Berberine treatment increased expression of skeletal muscle glucose transporter 4 mRNA and significantly decreased liver low density lipoprotein receptor mRNA expression. The study suggested that berberine was effective in lowering blood glucose and lipids levels, reducing the body weight, and alleviating the oxidative stress in diabetic hamsters, which might be beneficial in reducing the cardiovascular risk factors in diabetes.

AbstractObesity and the brain are linked since the brain can control the weight of the body through its neurotransmitters. The aim of the present study was to investigate the effect of high-fat diet (HFD)-induced obesity on brain functioning through the measurement of brain glutamate, dopamine, and serotonin metabolic pools. In the present study, two groups of rats served as subjects. Group 1 was fed a normal diet and named as the lean group. Group 2 was fed an HFD for 4 weeks and named as the obese group. Markers of oxidative stress (malondialdehyde, glutathione, glutathione-s-transferase, and vitamin C), inflammatory cytokines (interleukin [IL]-6 and IL-12), and leptin along with a lipid profile (cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein levels) were measured in the serum. Neurotransmitters dopamine, serotonin, and glutamate were measured in brain tissue. Fecal samples were collected for observing changes in gut flora. In brain tissue, significantly high levels of dopamine and glutamate as well as significantly low levels of serotonin were found in the obese group compared to those in the lean group (P > 0.001) and were discussed in relation to the biochemical profile in the serum. It was also noted that the HFD affected bacterial gut composition in comparison to the control group with gram-positive cocci dominance in the control group compared to obese. The results of the present study confirm that obesity is linked to inflammation, oxidative stress, dyslipidemic processes, and altered brain neurotransmitter levels that can cause obesity-related neuropsychiatric complications.

High-fat diet (HFD) consumption has been linked to dyslipidemia, low-grade inflammation and oxidative stress. This study investigated the effects of a mixed formulation with Limosilactobacillusfermentum 139, L. fermentum 263 and L. fermentum 296 on cardiometabolic parameters, fecal short-chain fatty acid (SCFA) contents and biomarkers of inflammation and oxidative stress in colon and heart tissues of male rats fed an HFD. Male Wistar rats were grouped into control diet (CTL, n = 6), HFD (n = 6) and HFD with L. fermentum formulation (HFD-Lf, n = 6) groups. The L.fermentum formulation (1 × 109 CFU/mL of each strain) was administered twice a day for 4 weeks. After a 4-week follow-up, biochemical parameters, fecal SCFA, cytokines and oxidative stress variables were evaluated. HFD consumption caused hyperlipidemia, hyperglycemia, low-grade inflammation, reduced fecal acetate and propionate contents and increased biomarkers of oxidative stress in colon and heart tissues when compared to the CTL group. Rats receiving the L. fermentum formulation had reduced hyperlipidemia and hyperglycemia, but similar SCFA contents in comparison with the HFD group (p < 0.05). Rats receiving the L. fermentum formulation had increased antioxidant capacity throughout the colon and heart tissues when compared with the control group. Administration of a mixed L. fermentum formulation prevented hyperlipidemia, inflammation and oxidative stress in colon and heart tissues induced by HFD consumption.

Background and Aim: Hyperlipidemia is an important risk factor for cardiovascular disease. The use of statins has adverse side effects that result in oxidative stress disorders. The objective of this study was to investigate the antihyperlipidemic effect of a combination of Cinnamomum burmannii and Eleutherine palmifolia extract in high-fat diet (HFD)-induced hyperlipidemia mice. Materials and Methods: Mice were divided into eight groups (n=4): Control group or healthy mice (normal), HFD-induced hyperlipidemic mice without any treatment (CE0), HFD-induced hyperlipidemic mice treated with 3.6 mg/kg body weight (BW) atorvastatin (atorvastatin), and HFD-induced hyperlipidemic mice treated with a combination of C. burmannii and E. palmifolia in the following ratios: 300:0 (C300), 225:75 (C225), 150:150 (CE150), 75:225 (E225), and 0:300 (E300). Mice were fed a HFD for 4 months to induce hyperlipidemia. Total cholesterol, cholesterol oxidase-peroxidase aminophenazone (CHOD-PAP), triglyceride-glycerine, and fat serum were analyzed with colorimetric method. The measurement of superoxide dismutase was done with the xanthine oxidase method and malondialdehyde measurement was done with the thiobarbituric acid method. Results: Results showed an increase in antihyperlipidemic characteristics as the concentration of E. palmifolia extract (p<0.05) increased. Duncan's multiple range test also showed an increase in anti-stress oxidation as the concentration of C. burmannii extract (p<0.05) increased. Conclusion: The E225 group showed the most potential as a safe, antihyperlipidemic agent characterized by improvement in lipid profile and antioxidant balance.
