Abstract
Objectives The purpose of this study was to evaluate the independent and combined effects of camelina sativa oil and high-intensity interval training (HIIT) on liver function, and metabolic outcomes in streptozotocin-induced diabetic rats. Methods Forty male Wistar rats were randomly assigned to five equal groups (8 per group): Normal control (NC), diabetic control (DC), diabetic + camelina sativa oil (300 mg/kg by oral gavage per day; D + CSO), diabetic + HIIT (running on a treadmill 5 days/week for 8 weeks; D + HIIT), diabetic + camelina sativa oil + HIIT (D + CSO + HIIT). Results In all three intervention groups (D + CSO, D + HIIT, and D + CSO + HIIT) compared to the DC, hepatic TNF-α, MDA, and histopathology markers, decreased and hepatic PGC-1α, and PPAR-γ increased (p < 0.05). However, the effect of D + CSO was greater than D + HIIT alone. Hepatic TG decreased significantly in D + HIIT and D + CSO + HIIT compared to other groups (p < 0.001). Fasting plasma glucose in all three intervention groups (D + CSO, D + HIIT, and D + CSO + HIIT) and HOMA-IR in D + CSO and D + CSO + HIIT were decreased compared to DC (p < 0.001). Only hepatic TAC and fasting plasma insulin remained unaffected in the three diabetic groups (p < 0.001). Overall, D + CSO + HIIT had the largest effect on all outcomes. Conclusions At the doses and treatment duration used in the current study, combination of CSO and HIIT was beneficial for reducing liver function and metabolic outcomes other than CSO and HIIT alone.

In Vitro Role of Pumpkin Parts as Pharma-Foods: Antihyperglycemic and Antihyperlipidemic Activities of Pumpkin Peel, Flesh, and Seed Powders, in Alloxan-Induced Diabetic Rats. INTERNATIONAL JOURNAL OF FOOD SCIENCE 2022; 2022:4804408. [PMID: 35959224 PMCID: PMC9363229 DOI: 10.1155/2022/4804408] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 06/20/2022] [Accepted: 07/16/2022] [Indexed: 11/18/2022]
Abstract
Pumpkin is a well-known vegetable, among the members of Cucurbitaceae family, due to its importance as pharma food. Keeping in view the antidiabetic and plasma lipids lowering potential of pumpkin, the present study was conducted to investigate that, which part of pumpkin (peel, flesh, and seeds), possess more bioactive compounds, exhibiting antihyperglycemic and antihyperlipidemic potential. Albino rats with 190-210 g body weight were divided into 11 groups. Five rats were included in each group; group A was negative control, group B was positive control, and groups C to K were diabetic rats fed with pumpkin peel, flesh, and seed powders. Diabetes was induced in rats with the help of alloxan monohydrate. During 28 days of experimental period, blood glucose level of different rat's groups was checked with the help of glucometer, at every 7 days interval and at the end of 28 days study, plasma lipids were checked with the help of commercial kits. A significant decrease in blood glucose level (128.33 ± 1.67 mg/dl), TC (88.43 ± 0.66 mg/dl), TG (69.79 ± 0.49 mg/dl), and LDL-C (21.45 ± 0.08 mg/dl) was recorded in rat groups fed with 15 g pumpkin seed powder, at the end of study. After pumpkin seeds, second significant antihyperglycemic and antihyperlipidemic effect was recorded in rat's groups fed with 15 g pumpkin peel powder. Pumpkin flesh powder effect in lowering blood glucose level and plasma lipids was less significant as compared to seeds and peel powder. As the dose of the pumpkin powders was increased from 5 to 10 and then 15 g, the blood glucose-lowering and plasma lipid-lowering effect became more significant. Similarly, as the experimental duration was expanded from first week to 28 days, this antihyperglycemic and antihyperlipidemic effect became more significant. These results were sufficient to conclude that pumpkin has high potential to be used in human diet to cope with noncommunicable diseases like diabetes and hypercholesterolemia.

Abstract
Composition and antioxidant properties of sixteen pecan [Carya illinoinensis (Wangenh) K. Koch] cultivars grown simultaneously in a single experimental orchard in Uruguay were evaluated to characterize their nutritional properties and nutraceutical potential. The percentage of oil, moisture, ash, minerals, and proteins were determined and also the fatty acid profile. Total phenolic compounds [18–41 mg gallic acid equivalents (GAEs)/g], condensed tannin [2–12 mg catechin equivalents (CEs)/g], and tocopherols (110–163 μg/g) contents were estimated in nut kernels. Total phenolic compounds (32–117 mg GAE/g), condensed tannins (130–357 mg CE/g), and total anthocyanins (1–3 mg 3-glucoside cyanidin/g) were also determined for pecan shells. The antioxidant activity in shells [57.15–578.88 μmol Trolox equivalents (TEs)/g] was 5 times higher compared with the kernels (23.15–156.60 μmol TEs/g) measured with hydrophilic ORAC. Bioactive compounds concentrations present statistically significant genetic variability between cultivars studied (p < 0.05). The presence of phenolic compounds was related with high-antioxidant capacity in kernels and shells, and a strong correlation between content of total phenolic compounds and condensed tannins in pecan shells was found. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) show association between cultivars and the observed variables. The nutritional profile in the different cultivars showed the trends described in other countries, but this work shows some significant differences that could be attributed to the specific edaphoclimatic conditions of cultivation in Uruguay.

Abstract
Pumpkin is a well-known multifunctional ingredient in the diet, full of nutrients, and has opened new vistas for scientists during the past years. The fruit of pumpkin including the flesh, seed, and peel are a rich source of primary and secondary metabolites, including proteins, carbohydrates, monounsaturated fatty acids, polyunsaturated fatty acids, carotenoids, tocopherols, tryptophan, delta-7-sterols, and many other phytochemicals. This climber is traditionally used in many countries, such as Austria, Hungary, Mexico, Slovenia, China, Spain, and several Asian and African countries as a functional food and provides health promising properties. Other benefits of pumpkin, such as improving spermatogenesis, wound healing, antimicrobial, anti-inflammatory, antioxidative, anti-ulcerative properties, and treatment of benign prostatic hyperplasia have also been confirmed by researchers. For better drug delivery, nanoemulsions and niosomes made from pumpkin seeds have also been reported as a health promising tool, but further research is still required in this field. This review mainly focuses on compiling and summarizing the most relevant literature to highlight the nutritional value, phytochemical potential, and therapeutic benefits of pumpkin.

Abstract
Oxidative stress can lead to chronic inflammation, nephrotoxicity, and renal damage. The consumption of plant-based dairy alternatives has increased rapidly worldwide due to their health effects. Bioactive components from natural sources, such as plants, are effective in protecting against oxidative stress. The present study evaluated the physicochemical and sensory properties of fermented camel milk made from camel milk mixed with pumpkin seed milk. Fermented camel milk consists of camel milk mixed with 25% and 50% pumpkin seed milk. This blend (fermented camel milk containing 50% pumpkin seed milk) was evaluated as an antioxidant agent in oxidative stress induced rats. A total of thirty-two male adult albino rats of Sprague Dawley® Rat strain weighing 150–180 g were randomly divided into four groups (n = 8). The first group was solely administered the standard diet and served as the negative control. The other rats (n = 24), received a basal diet, including being intraperitoneally injected with carbon tetrachloride, with a single dose at a rate of 2 mL/kg body weight) as a model for oxidative stress. The oxidative stress rats were divided into three groups; the first group did not receive any treatment and served as the positive control. The second and third groups were administered 10 g/day fermented camel milk and fermented camel milk containing 50% pumpkin seed milk. The results revealed that mixing the camel milk with pumpkin seed milk was more effective in increasing the total solids, protein, ash, fiber, acidity, viscosity, phenolic content, and antioxidant activity. These enhancements were proportional to the mixing ratio. Fermented camel milk containing 50% pumpkin seed milk exhibited the highest scores for sensory properties compared with the other fermented camel milk treatments. The group of rats with oxidative stress treated with fermented camel milk containing 50% pumpkin seed milk showed a significant decrease (p ≤ 0.05) in the levels of malondialdehyde (MDA), low-density lipoprotein (LDL), cholesterol (CL), triglycerides (TGs), AST, ALT, creatinine, and urea, and increased (p ≤ 0.05) high-density lipoprotein (HDL) and total protein and albumin compared with rats with oxidative stress. Consumption of fermented camel milk containing 50% pumpkin seed milk by the oxidative stress rat groups caused significant improvement in all of these factors compared with the positive control group. This study revealed that the administration of fermented camel milk containing 50% pumpkin seed milk to rats with oxidative stress prevented disorders related to oxidative stress compared with the untreated oxidative stress group. Thus, incorporating fermented camel milk might play a beneficial role in patients with oxidative stress.

Abstract
Numerous randomized controlled trials (RCTs) and meta-analyses have assessed the effects of supplemental dietary polyunsaturated fatty acids (PUFAs) on levels of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) and the LDL/HDL ratio in patients receiving renal replacement therapy (RRT). However, results are ambiguous due to mixed reports of various nutrients used in the intervention group. We performed a network meta-analysis of RCTs to assess the effects of PUFAs on lipid profiles in patients undergoing RRT. RCTs performed before November 2021 were gathered from three databases. The means, standard deviations and the number of cases for each arm were independently extracted by two authors to form a network meta-analysis of LDL and HDL levels and the LDL/HDL ratio in a random effects model. Twenty-eight RCTs (n = 2017 subjects) were included in this study. The pooled results revealed that the combination of omega-3 fatty acids (n-3) and omega-6 fatty acids (n-6) produced significantly lower LDL (standardized mean difference (SMD) = −1.43, 95% confidence interval: −2.28 to −0.57) than the placebo. Both n-3 fatty acids (SMD = 0.78) and the combination of n-3 + n-6 (SMD = 1.09) benefited HDL significantly compared with placebo. Moreover, n-3 alone also exhibited a significantly lower LDL/HDL ratio than placebo. Collectively, PUFAs seem to be adequate nutrients for controlling lipoproteins in patients undergoing RRT. Specifically, n-3 + n-6 supplementation improved LDL levels, while n-3 improved HDL levels and the LDL/HDL ratio. However, our data provide limited information on specific dosages of PUFAs to form a concrete recommendation.

Abstract
Flaxseed (FS) and sesame seed (SS) are traditional and functional foods in traditional Indian medicine for treating various disorders. The present study investigated the hepatoprotective effects of bioactive-fatty acids (FAs) from FS and SS against carbon tetrachloride (CCl4)-induced hepatic damage in rats. Pre and post-treatments for 28 consecutive days significantly increased the activities of in vivo antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), and peroxidase (POX), whereas, lipid peroxidation (LPO) activity was markedly decreased in a dose-dependent manner in liver and kidneys. A significant reduction was observed in the hematological parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin in the serum of post-treated animals compared to the negative control. The results were confirmed histopathologically. The results suggested that the ω-3 and ω-6 FAs from flaxseed oil (FSO) and sesame seed oil (SSO), respectively, showed potential synergistic hepatoprotective and antioxidant effects that were mediated mainly by ω-3 and ω-6 FAs present in the respective seed oils.

Abstract
Epidemiology and pathogenesis of cardiovascular diseases (CVD) and osteoporosis are strikingly overlapping. This study presents matrix metalloproteinase-9 (MMP-9), as a simple molecular link more consistently associated with the pathophysiology of both osteoporosis and CVD risk factors. 40 adult female rats were randomly distributed into 4 groups [control sham-operated, untreated osteoporosis, carvedilol-treated osteoporosis and alendronate-treated osteoporosis]. After 8 weeks, blood samples were collected to estimate Lipid profile (Total cholesterol, HDL, Triglycerides), inflammatory markers (IL-6, TNF alpha, CRP and NO), and Bone turnover markers (BTM) (Alkaline phosphatase, osteocalcin and pyridinoline). The tibias were dissected to estimate MMP-9 and NF-kB gene expression, OPG, RANKL levels and for histological examination. Induction of osteoporosis resulted in a significant elevation in BTM, inflammatory markers and dyslipidemia. MMP-9 was significantly elevated and positively correlated with BTM, inflammation and dyslipidemia markers. Carvedilol and alendronate exerted a bone preservative role and attenuated dyslipidaemia and inflammation in accordance with their respective effect on MMP-9.

Abstract
Materials and Methods Hydroalcoholic extractions of pumpkin fruit peel were obtained and used to prepare two different cold cream-based formulations, namely, 10% and 20% pumpkin peel extracts (PPEs). These formulations, phenytoin cream, and cold cream were topically used once daily for 14 days to compare their wound-healing effects in a rat model of excision wound repair. Wound sizes were monitored at different intervals. Skin tissue samples were subject to H&E staining for histopathological analysis. Blood samples were also taken on day 14 to measure serum levels of nitrite. Results Both 10% and 20% PPE formulations resulted in a significant reduction of wound sizes compared to positive and negative controls. Wound closure rate was estimated to be higher in 20% PPE-treated rats. According to histopathological analysis, treatment with 20% PPE improved parameters associated with efficient wound repair, including better regeneration of epidemic layer, higher density of dermis collagen fibers, and lower presence of inflammatory cells. Also, both formulations lowered serum concentrations of nitrite. Conclusion Given the obtained data from our study, the hydroalcoholic extract of Cucurbita moschata Duchesne fruit peel is proposed to be effective in accelerating the process of excision wound repair partly due to its antioxidant effect in terms of decreasing nitrite concentration.

Abstract
Trichosanlhes kirilowii Maxim seed oil (TSO) is rich in conjugated linolenic acids, and the flavonoids (FLA) combined with n-3 fatty acids can effectively change the plasma antioxidant capacity. Hyperlipidemia and oxidative stress are one of the most important risk factors for cardiovascular disease. This study aims to evaluate the effect of the TSO, FLA, and TSO combined with FLA (TSOFLA) intake on hyperlipemia mice. TSO and TSOFLA administration resulted in a significant decline in serum levels of total cholesterol, triglycerides, and low density lipoprotein-cholesterol. TSOFLA improved the hepatic and serum antioxidant status as assessed by superoxide dismutase, glutathione peroxidase activities, and reduced the levels of lipid peroxidation. Hematoxylin-eosin staining of liver and aorta tissue has shown a marked reduction of the hyperlipidemia-induced lesions by gavage TSOFLA. Compared with TSO and FLA, TSOFLA has more significant hypolipidemic and antioxidant activities, which effects may be correlated to the synergy between TSO and FLA. PRACTICAL APPLICATIONS: Dyslipidemia is a common metabolic disorder, which is characterized by triglyceride levels increased, total cholesterol, and low-density lipoprotein cholesterol. Lipid-lowering treatment can reduce the expansion of coronary atherosclerosis, and particular the dietary lipids have important roles in controlling the concentrations of these risk factors. This is the first study evaluating the hypolipidemic and antioxidant activities effects of Trichosanlhes kirilowii Maxim seed oil (TSO), flavonoids (FLA), and TSO combined with FLA (TSOFLA) intake on hyperlipemia mice caused by a high-fat diet. The pharmacological effects of dietary TSOFLA are correlated to its high content of unsaturated fatty acids and flavonoids. This information can be of interest to the development of food supplements in the field of diseases associated with high-fat intakes such as cardiovascular diseases and adiposis.

Tendril and Their Osteoclast Differentiation Inhibitory Activities. Molecules 2020; 25:molecules25092077. [PMID: 32365620 PMCID: PMC7248980 DOI: 10.3390/molecules25092077] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 04/16/2020] [Accepted: 04/28/2020] [Indexed: 12/12/2022] Open
Abstract
Six new 8-C-p-hydroxybenzylflavonol glycosides were isolated from a hot water extract of pumpkin (Cucurbita moschata Duch.) tendril and elucidated as 8-C-p-hydroxybenzylquercetin 3-O-rutinoside, 8-C-p-hydroxybenzoylquercetin 3-O-β-D-glucopyranoside, 8-C-p-hydroxybenzylkaempferol 3-O-(α-L-rhamnopyranosyl(1→6)-β-D-galactopyranoside, 8-C-p-hydroxybenzoylkaempferol 3-O-rutinoside, 8-C-p-hydroxybenzylisorhamnetin 3-O-rutinoside, and 8-C-p-hydroxybenzylisorhamnetin 3-O-(α-L-rhamnopyranosyl(1→6)-β-D-galactopyranoside. Their chemical structures were determined using nuclear magnetic resonance (NMR) and electrospray ionization-mass spectrometer (ESIMS) analyses. The 8-C-p-hydroxybenzylflavonol glycosides were found to inhibit the receptor activator of nuclear factor-κB (RANKL)-induced osteoclast differentiation of bone marrow derived macrophage (BMDM), an osteoclast progenitor. Additionally, 8-C-p-hydroxybenzylflavonol glycosides effectively reduced the expression of osteoclast-related genes, such as tartrate-resistant acid phosphatase, cathepsin K, nuclear factor activated T-cell cytoplasmic 1, and dendritic cell specific transmembrane protein in RANKL-treated BMDMs. These results indicate that the 8-C-p-hydroxybenzylflavonol glycosides may be the main components responsible for the osteoclast differentiation inhibitory effect of pumpkin tendril.

Abstract
BACKGROUND Nitrate (NO3) is the most common chemical contaminant in the world's ground water aquifer. Oxidative stress has been proposed as a possible mechanism involved in NO3 toxicity on non-target organism. OBJECTIVES The current study aimed to elucidate the potential protective effect of Telfairia occidentalis (pumpkin seed oil, PSO) against hepatotoxicity induced by sodium nitrate. METHODS Wistar rats were exposed either to NaNO3 (200 mg/kg bw) in drinking water in drinking water, or to 4ml PSO/kg bw by gavage or to their combination. Oxidative stress parameters, biochemical biomarkers and liver histopathological examination were determined. RESULTS Our data showed that the exposure of rats to NaNO3 caused significant changes of some haematological parameters compared to the control. In addition, there was a significant elevation of the levels of biochemical markers as that of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and lactate dehydrogenase when compared with the control. Furthermore, exposure of rats to NaNO3 induced liver oxidative stress as indicated by the increase of malondialdehyde, progressive oxidation of protein products and protein carbonyl levels. In addition, a reduction in anti-oxidant status (catalase, glutathione peroxidase, glutathione-S-transferase and superoxide dismutase, reduced glutathione and vitamin C) was observed. CONCLUSION Co-administration of PSO to the NaNO3 restored most parameters cited above to near-normal values. Therefore, the present investigation revealed the ability of PSO to attenuate NaNO3-induced oxidative damage.

Abstract
The effects of fipronil (FPN) on the liver of rats were studied. Rats (n = 6) were treated with 9.7 mg/kg (1/10 of FPN LD50), and other rats (n = 6) received 120 mg/kg of 10% Uncaria tomentosa extract, while a mixture of 9.7 mg/kg FPN and 120 mg/kg of 10% Uncaria tomentosa extract were administered orally to the rats (n = 6) daily for 6 weeks. Body, hepatic weights, liver enzymes, and lipid profile were determined. Hepatic activities of MDA, TNO, TAC, TNF-α, and IL-6 in liver homogenate were measured. Immunohistochemistry of NF-kB and liver histopathology were performed. Fipronil-treated rats had a significant (P = 0.02) lower weight gain. Moreover, relative liver weight was significantly (P = 0.003) increased in FPN-treated rats. Rats administrated with FPN exhibited a significantly (P = 0.02) higher liver enzymes and promoted levels of MDA, TNO, TNF-α, and IL-6 (P < 0.0001) than that in the other groups. Immunostaining of NF-κB was increased (P < 0.0001) in FPN-treated rats. Interestingly, Uncaria tomentosa alone or with FPN decreased the liver immunostaining of NF-κB. In conclusion, FPN produced liver injury through lipid peroxidation and stimulation of NF-κB. However, Uncaria tomentosa combated the oxidative stress and liver damage induced by FPN via inhibition of NF-κB.

Abstract
BACKGROUND The tamarind seeds have a lot of nutrients that may be used to control cholesterol or glucose levels. OBJECTIVE(S) The effects of tamarind seeds (T) on lipid and carbohydrate metabolism in rats were studied. Rats were offered basal diet (BD) with T (2%, 4% or 8%) or without T. MATERIALS AND METHODS Feeding and growth performance in rats were measured and samples of liver and blood were analyzed for glycogen content and levels of cholesterol and glucose respectively. RESULTS The inclusion of T in the diet influences the feeding and growth performance in rats. The serum cholesterol level was reduced (p < 0.05) in Sprague Dawley (SD) rats fed on basal diet (BD) containing 4% and 8% T (0.24 ± 0.14 g/l and 0.31 ± 0.06 g/l respectively) compared to control (0.79 ± 0.04 g/l). The serum glucose levels in the spontaneous hypertensive rats (SHR) was lower (50.74 ± 2.50 mg/dl; p < 0.05) than control (93.52 ± 10.83 mg/dl) at 4% T. Incorporation of increasing doses of T resulted in linear increase of glycogen storage in livers of SD rats fed on BD and high sucrose diet. CONCLUSION Tamarind seeds can lower blood glucose and serum cholesterol and enhance storage of glycogen in rats.

Abstract
Background Cancer is one of the most important public health burdens in developed and developing countries. Colon cancer (CC) is the sixth most common cause of death in India and third most important cause in developed countries. For treating cancer, several synthetic agents are available but they cause side effects. Therefore, there is a need to investigate plant derived anticancer agents with lesser side effects. In this direction, we have made an attempt to unravel the potential of pumpkin seed extract for treating colon cancer. Objective The objective of this study was to evaluate pumpkin seed extract as prophylactic and treatment for 1, 2-dimethylhydrazine (DMH) induced colon cancer in Wistar rats. Materials and Methods Male Wistar rats were divided into seven groups, namely, control, DMH (disease control), 5-Flurouracil (standard), treatment groups (100mg/kg and 200 mg/kg), and pretreatment groups (100mg/kg and 200 mg/kg) with pumpkin seed extract. The animals were euthanised at the end of study and colons were examined. Results A significant difference in the aberrant crypt foci (ACF) number in all treatment groups compared to control and DMH groups were noted. Pretreatment group at a dose of 200 mg/kg showed a significant decrease in the colon length/weight ratio. Pretreatment groups showed a significant change in the colonic glutathione (GSH) and superoxide dismutase (SOD) levels when compared to control and DMH control. The nitrite content was decreased in treatment group 200 mg/kg at 5.203±0.852 when compared to DMH control at 8.506±3.866. All treatment groups demonstrated decreased hyperplasia and ACF in histology. Conclusion Pumpkin seed may prevent the risk of CC when consumed in dietary proportions.

Abstract
Purpose: Cucurbita maxima Duchense (C. maxima) has been widely used in China and Mexico as a hypoglycemic plant for controlling blood glucose in diabetic patients. Furthermore, in northwest of Iran, this plant is used traditionally for controlling of diabetes. We examined the effect of C. maxima pulp besides insulin on control of hyperglycemia in diabetic patients admitted to Intensive care unit (ICU). Methods: Twenty critically ill patients who were admitted to the ICU were enrolled in this study. 5g lyophilized powder of C. maxima was administrated every 12 hours for 3 days. Moreover, blood glucose level and insulin dose were measured every 1-4 hours during 3 days before administration and 3days at the time of C. maxima administration. Results: The average of glucose level in 3 days before C. maxima administration was 214.9 ± 55.7 mg/dl, while in 3 days during C. maxima administration it was decreased to 178.4 ± 36.1 mg/dl (P<0.001). Additionally, the average insulin dose during 3 days before intervention was 48.05 ± 36.5 IU and during the 3 days of C. maxima administration was decreased to 39.5 ± 27.8 IU (P=0.06). Conclusion: It seems that C. maxima may decrease high blood glucose level fast and effective in diabetic critically ill patients.

Abstract
Hyperlipidemia is one of the major risk factors for atherosclerosis and ischemic heart disease. Chromium (Cr) mineral is playing a crucial role in glucose and lipid homeostasis. The aim of this study was to evaluate the protective effects of combined chromium picolinate (CrPic) and atorvastatin treatment against hyperlipidemia-induced cardiac injury. Seventy-five male albino rats were divided into five groups (15 rats each). Hyperlipidemia was induced by intraperitoneal injection of a single dose of Triton X-100 (300 mg/kg body weight (b.w) (group ІІ). Treatment of hyperlipidemic rats was induced by daily administration of CrPic at a dose of 200 μg/kg b.w/day (group ІІІ), atorvastatin at a dose of 10 mg/kg/day (group IV), and combined treatment with both (group V) by gavage for 7 days. At the end of experiment, serum and heart tissues were obtained. Hyperlipidemia was confirmed by histopathology of heart tissues, marked serum dyslipidemia, increased atherogenic indices, and values of ischemia-modified albumin. In addition to increased values of proprotein convertase subtilisin/kexin type 9, activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase enzyme and high relative expression levels of pentraxin-3 were observed. However, paraoxonase-1 activity was markedly decreased in the hyperlipidemic group. Significant improvement in all assessed parameters was observed in the rat group treated with both CrPic and atorvastatin. It can be concluded that combined CrPic and atorvastatin treatments had synergistic cardioprotective effects against hyperlipidemia which may be through modulating atherosclerosis as well as cardiac and aortic damage and/or activation of anti-inflammatory and anti-oxidant pathways, thus reversing endothelial dysfunction.

[PMID: 29333185 PMCID: PMC5733178 DOI: 10.1155/2017/6405789] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/19/2017] [Revised: 10/27/2017] [Accepted: 11/01/2017] [Indexed: 12/24/2022]
Abstract
Flaxseed (Linum usitatissimum L.) is a multipurpose crop with health promoting potential. This study was undertaken to investigate the fatty acid profile and yield of fixed oil of six Egyptian flaxseed cultivars. The selected cultivars with the highest content of polyunsaturated fatty acids (PUFAs) (G9 and G10) were assessed for their antidepressant-like effect in rat model of postpartum depression (PPD) induced by hormone-simulated pregnancy followed by hormone withdrawal and compared to fluoxetine. As compared to control group, administration of G9 and G10 (270 mg/kg/day, p.o) for two weeks during the postpartum period can alleviate anxiety and depressive-like behaviors and biochemical changes in PPD-induced rats. This was confirmed by evaluation of anxiety-like behaviors (elevated plus maze, open field test, and forced swim test tests), in addition to biochemical analysis (brain monoamine oxidase-A, corticosterone level, proinflammatory cytokines, and hippocampal redox state). In conclusion, flaxseed oil of Egyptian cultivars G9 and G10 exhibited significant antidepressant-like effect in rat model of PPD without affecting locomotor activity. At the treatment doses, the antidepressant-like activity of Giza 9 oil is comparable to fluoxetine.

Abstract
BACKGROUND Metabolic syndrome (MetSyn) increases the risk of type II diabetes and morbidity and mortality due to cardiovascular diseases. Flaxseed oil (FO), as a functional food, is one of the major vegetal sources of essential omega-3 fatty acids. OBJECTIVE This study aimed to compare the effects of consumption of FO and sunflower seed oil (SO) on lipid peroxidation and other symptoms of MetSyn. METHODS This randomized controlled interventional trial was conducted on 60 volunteers aged 30 to 60 years who were diagnosed with MetSyn in Shiraz, Iran. The participants who fulfilled the inclusion criteria were randomly assigned to SO (n = 30, receiving 25 mL/d SO) and FO (n = 30, receiving 25 ml/d FO) groups using block randomization. The diets were identical for all the participants. Blood pressure (BP), serum lipid, fasting blood sugar, and malondialdehyde were measured at baseline and at the end of week 7. RESULT The results showed no significant difference between the 2 groups regarding blood lipid levels and fasting blood sugar at the end of the study. However, significant reductions in total cholesterol, low-density lipoprotein cholesterol (5.6% in FO and 10.8% in SO), and triglyceride levels were seen within each group after treatment with FO and SO (P < .05). Nonetheless, between-group changes were significant (<0.05) for systolic BP (mean [±standard deviation {SD}] changes were -14.0 ± 22.41 in the FO group [P = .004] and 0.92 ± 8.70 in the SO group [P = .594]) and diastolic BP (mean [±SD] changes were -4.26 ± 7.44 in the FO group [P = .007] and 1.30 ± 6.91 in the SO group [P = .344]), but marginally significant (P = .053) for malondialdehyde level (mean [±SD] changes were -1.29 ± 1.48 in the FO group [P < .001] and -0.52 ± 1.34 in the SO group [P = .52]). A significant decrease in weight was also found in both groups. However, waist circumference decreased significantly only in the FO group at the end of the study (P < .05). CONCLUSION Our results indicated that dietary FO could be effective in amelioration of some symptoms of MetSyn and decrease BP and lipid peroxidation.

Abstract
Background Prevention and treatment of obesity is a way to reduce cardiovascular disease, diabetes and depression. Pumpkin as a favorable plant has different properties notably antioxidant, lipid-lowering and anti-diabetic potential. The aim of this study was to assess the anti-obesity effects of pumpkin in diet-induced obese rats. Methods Thirty adult male Wistar rats were randomly divided into five groups (n=6) of healthy control, dietary fatty control rats, and three experimental dietary fatty rats that received hydro-alcoholic extract of pumpkin once daily at doses 100 and 200 and 400 mg/kg, respectively. At the end of 6 weeks, lipid profile, atherogenicity, liver enzymes, and oxidative stress status were measured. Results Pumpkin in a dose-dependent manner dramatically decreased triglycerides and low-density lipoprotein, and liver enzymes while high-density lipoprotein was markedly increased in treated groups. Pumpkin also increased glutathione level in comparison with obese control group. Conclusions Pumpkin ameliorated oxidative stress and dyslipidemia in obese rats, leading to decrease cardiovascular disease risk in obesity.

Abstract
To the best of our knowledge, this is the first report in the literature concerning the bioactive properties of faveleira products. This work focuses on the physicochemical evaluation of faveleira oil, as well as it investigates the bioactive properties of faveleira seeds, faveleira oil and the press cake obtained during the oilseed processing. The seeds were cold pressed and the following tests were performed: physicochemical characteristics (acidity, peroxide values, moisture and volatile matter, density and viscosity) and fatty acid profile of faveleira oil; total phenolic and flavonoid content of faveleira seed and press cake; antibacterial activity of seed, oil and press cake; and antioxidant activity (DPPH radical scavenging activity, reducing power assay, total antioxidant capacity, superoxide radical scavenging assay and oxygen radical absorbance capacity) of seed, oil and press cake. Our work demonstrated that the faveleira seed oil has low acidity (0.78 ± 0.03% oleic acid) and peroxide value (1.13 ± 0.12 mEq/1000g), associated with the relevant concentration of linoleic acid (53.56%). It was observed that important phenolics (398.89 ± 6.34 mg EAG/100 g), especially flavonoids (29.81 ± 0.71 mg RE/g) remain in the press cake, which indicates that the by-product of the faveleira oilseed production constitutes a rich residual source of bioactive compounds. No bacterial growth inhibition was detected, but all samples including faveleira seeds, press cake, oil and its fractions have potent antioxidant activities, mainly the press cake, with oxygen radical absorbance capacity of 28.39 ± 4.36 μM TE/g. Our results also show that faveleira oil has potential to be used as edible oil and the press cake should be used to contain the most antioxidants from seed.

Abstract
This study was aimed to determine the acylglycerols composition, quality characteristics, and protective role of dietary pumpkin seed oil (PSO) in rabbits. PSO was thermally oxidized and analyzed for quality characteristics and acylglycerols composition using reversed phase high performance liquid chromatography with diode array detection (HPLC-DAD). Oxidized and un-oxidized oil samples were fed to the rabbits in different doses for 2 weeks. The changes in the serum biochemistry, hematology, and liver histology were studied. The levels of quality parameters such peroxide value (PV), anisidine value (AV), total phenolic contents (TPC), thiobarbituric acid reactive substances (TBARS), conjugated dienes (CD) and conjugated trienes (CT) significantly increased with thermal treatment. HPLC analyses revealed 10 individual triacylglycerols (TAGs), total di-acylglycerols (DAGs), mono-acylglycerols (MAGs), and total oxidized TAGs. Trilinolein (LLL), 1-oleoyl-2,3-dilinolinoyl glycerol (OLL), triolein (OOO) and 1,2-distearoyl-3-palmitoyl glycerol (SSP) were present in higher amounts and decreased with thermal treatment. Animal's studies showed that oxidized oils decreased the whole body weight, which was ameliorated by the co-administration of un-oxidized oils. The levels of serum biochemical parameters were improved by co-administration of pumpkin seed oils. There were no significant effects of both oxidized and un-oxidized PSO on the hematological and histological parameters of rabbits. In conclusion, nutritionally important triacylglycerols were present in PSO with protective role against the toxicity of its corresponding oxidized oils.

Abstract
Cucurbita moschata Duch. has long been used for traditional health food in many countries. However, to enhance the immune system of Cucurbita moschata Duch. and its major component, β-carotene is not clear. Here, we determined the immune enhancement effect of Cucurbita moschata Duch. and β-carotene in mouse splenocytes and RAW 264.7 macrophage cell line. We prepared baked Cucurbita moschata Duch. (Sweetme Sweet Pumpkin(TM), SSP) and steamed Cucurbita moschata Duch. (SC). Splenocytes isolated from the spleen of BALB/c mice were treated with SSP, SC, and β-carotene for 24 h. RAW 264.7 cells were stimulated with recombinant interferon-γ (rIFN-γ) for 6 h before treatment with SSP, SC, or β-carotene. SSP, SC and β-carotene significantly up-regulated the proliferation of splenocyte and mRNA expression of KI-67. The levels of interleukin-2 and IFN-γ were up-regulated by SSP, SC, or β-carotene in the splenocytes. SC and β-carotene also increased the levels of tumor necrosis factor-α (TNF-α) in the splenocytes. In addition, SSP, SC, or β-carotene significantly increased the levels of TNF-α through the nuclear translocation of the nuclear factor-κB and phosphorylation of IκBα in the rIFN-γ-primed RAW 264.7 cells. These data indicate that Cucurbita moschata Duch. and β-carotene may have an immune-enhancing effect through the production of Th1 cytokines by activation of splenocytes and macrophages.

Abstract
Keeping in mind the beneficial effects of GTE administration on liver damage, the present study was undertaken to evaluate the hepatoprotective effect of green tea extract (GTE) against carbon tetrachloride (CCl4)-induced liver injuries in male hamsters for 8 weeks. Twenty hamsters were equally divided into 4 groups, the control ones (group I) received only dis. water. Hamsters of group II had free access to 10% of GTE, while hamsters of group III received 1 ml/kg of 50% CCl4 in corn oil via gavage daily. Hamsters of group IV (GTE + CCl4) received a free access to GTE supplementation in combination with 1 ml/kg of 50% CCl4 in corn oil via gavage daily. Lipid profile, hepatic enzyme levels and apoptosis molecular marker (p53) were investigated in hamsters. GTE + CCl4 treated hamsters showed lower levels of hepatic malondialdehyde (MDA) than CCl4 exposed hamsters. Hepatic activity levels of GSH, ALD and cytochrome 450 reductase were declined after CCl4 administration while they were remarkably improved with GTE administration. Serum lipid profiles as T-cholesterol (TC), triglyceride (TG) and low density lipoproteins (LDL) were improved in GTE and CCl4 treated hamsters than CCl4 group. Moreover, hepatic tissue damage and p53 expression induced with CCl4 were improved with the treatment of GTE. These results suggested that GTE possesses hepatoprotective properties against the effect of CCl4.

Abstract
Flaxseed cake containing antioxidants is a valuable dietary component. Its nutritional effect may be diminished by the presence of anti-nutrients. The work was aimed at determining the effect of different contents of flaxseed cake in diets and their administration period on the development of rats and selected parameters of their health status. Diets with 15% and 30% addition of genetically modified (GM) flax seed cake with enhanced synthesis of polyphenols, as well as Linola non-GM flax were administered in short-term (33 days) and long-term (90 days) experiments. The 30% addition of flaxseed cake reduced digestibility of dietary nutrients, GM flaxseed cake lowered body weight gains. The relative weight of selected organs, hematological blood markers and serum activities of aspartate and alanine aminotransferases (AST, ALT) were not affected. Flaxseed cake consumption reduced serum concentration of albumins and increased globulins. Administration of 30% flaxseed cake improved plasma total antioxidant status and 30% GM flaxseed cake lowered liver thiobarbituric acid reactive substances. The activities of superoxide dismutase in erythrocytes, glutathione peroxidase in plasma and the liver concentration of 8-oxo-2′-deoxyguanosine were not changed. Most morphometric parameters of the small intestine did not differ between feeding groups. The administration of diets with 30% addition of flaxseed cake for 90 days improved the antioxidant status in rats.

Abstract
BACKGROUND AND PURPOSE Dehydrodiconiferyl alcohol (DHCA), a lignan compound isolated from Cucurbita moschata, has previously been shown to contain anti-adipogenic and antilipogenic effects on 3T3-L1 cells and mouse embryonic fibroblasts. As some of phytochemicals derived from natural plants show anti-inflammatory or antioxidative activities, we determined whether DHCA affects the production of pro-inflammatory mediators and also investigated its underlying mechanisms. EXPERIMENTAL APPROACH Raw264.7, a murine macrophage cell line, and primary murine macrophages derived from bone marrow cells were treated with LPS in the presence of DHCA. Furthermore, cells were treated with LPS and palmitate in the presence of DHCA to examine its effect on inflammasomes. The production of various pro-inflammatory mediators was examined and the underlying mechanisms investigated using a variety of molecular biological techniques. To test whether DHCA exhibits anti-inflammatory effects in vivo, mouse dextran sodium sulfate (DSS)-induced colitis model was used. KEY RESULTS DHCA reduced the production of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β and CCL2) and mediators (iNOS, COX-2 and ROS) by down-regulating the activity of I-κB kinase and, subsequently, the DNA binding activity of NF-κB. Moreover, DHCA effectively suppressed the palmitate-mediated activation of inflammasomes, which resulted in decreased production of IL-1β. DHCA also showed therapeutic effects in the mouse DSS-induced colitis model by suppressing the production of TNF-α and IL-1β and thus preventing weight loss and colon shrinkage. CONCLUSIONS AND IMPLICATIONS Our data suggest that DHCA is a novel phytochemical that by regulating key molecules involved in inflammation and oxidative stress might exert a broad range of anti-inflammatory activities.

Abstract
BACKGROUND Palm kernel cake (PKC), the most abundant by-product of oil palm industry is believed to contain bioactive compounds with hepatoprotective potential. These compounds may serve as hepatoprotective agents which could help the poultry industry to alleviate adverse effects of heat stress on liver function in chickens. METHODS This study was performed to evaluate the hepatoprotective potential of PKC extract in heat-induced oxidative stress in chicken hepatocytes. The nature of the active metabolites and elucidation of the possible mechanism involved were also investigated. RESULTS The PKC extract possessed free radical scavenging activity with values significantly (p < 0.05) lower than silymarin as the reference antioxidant. Heat-induced oxidative stress in chicken hepatocyte impaired the total protein, lipid peroxidation and antioxidant enzymes activity significantly (p < 0.05). Treatment of heat-induced hepatocytes with PKC extract (125 μg/ml) and silymarin as positive control increased these values significantly (p < 0.05). The real time PCR and western blot analyses revealed the significant (p < 0.05) up-regulation of oxidative stress biomarkers including TNF-like, IFN-γ and IL-1β genes; NF-κB, COX-2, iNOS and Hsp70 proteins expression upon heat stress in chicken hepatocytes. The PKC extract and silymarin were able to alleviate the expression of all of these biomarkers in heat-induced chicken hepatocytes. The gas chromatography-mass spectrometry analysis of PKC extract showed the presence of fatty acids, phenolic compounds, sugar derivatives and other organic compounds such as furfural which could be responsible for the observed hepatoprotective activity. CONCLUSION Palm kernel cake extract could be a potential agent to protect hepatocytes function under heat induced oxidative stress.

Abstract
BACKGROUND Plant seeds have gained interest for their health benefits due to their fatty acid content. The objective of this study was to determine the effects of dietary consumption of milled sesame/pumpkin/flax seed mixture on glycemic control, serum lipids, phospholipid fatty acid status, and inflammatory factors in patients on hemodialysis. METHODS Thirty patients with well nutrition status (18 male, 12 female) were enrolled in the study. Participants consumed 30 g of milled sesame/pumpkin/flax (6 g/6 g/18 g, resp.) seeds mixture added to their habitual diet. RESULTS Total n-6 and n-3 polyunsaturated fatty acids and levels of linoleic, dihomo-gamma-linolenic (DGLA), arachidonic, alpha-linolenic (ALA), eicosapentaenoic, docosapentaenoic, and docosahexaenoic (DHA) acid were increased after 12 weeks of supplementation. A significant decrease of the serum triglyceride level (P < 0.001), glucose, insulin, calculated IR HOMA (P < 0.05), and inflammatory markers (TNF-alpha, IL-6, and hs-CRP, P < 0.001) was observed after seed mixture treatment. The serum levels of CRP and TNF-alpha negative correlate with ALA, DHA, and DGLA. CONCLUSION Results of this study indicated that dietary milled sesame/pumpkin/flax seed mixture added to a habitual diet lowered triglyceride and CRP, TNF-alpha, IL-6 levels, affect glycemic control and improved fatty acid profile and pruritus symptoms in hemodialysis patients.

'Ashvagandharishta' prepared using yeast consortium from Woodfordia fruticosa flowers exhibit hepatoprotective effect on CCl4 induced liver damage in Wistar rats. JOURNAL OF ETHNOPHARMACOLOGY 2013; 151:183-190. [PMID: 24211394 DOI: 10.1016/j.jep.2013.10.025] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2013] [Revised: 09/22/2013] [Accepted: 10/07/2013] [Indexed: 06/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE [corrected] Consortium of yeasts sourced from traditionally used Woodfordia fruticosa flowers proved to be beneficial for fermenting Ashvagandharishta. It resulted in faster fermentation, acceptable organoleptic properties and demonstrable hepatoprotective potential in CCl4 induced hepatotoxicity. To formulate Ashvagandharishta using consortium of yeasts and to investigate its physiochemical parameters. Standardize the formulation with the help of standard withaferin-A and withanolide-A and to evaluate its hepatoprotective potential in CCl4 induced hepatotoxicity in the rat model. MATERIAL AND METHODS Ashvagandharishta was prepared using a 5% consortium of yeasts and ascertained its quality through physiochemical and phytochemical investigation. Withaferin-A and withanolide-A was simultaneously estimated by HPLC for standardization. Hepatoprotective potential was evaluated by administering 2.31 and 1.15 ml/kg doses while considering biochemical parameters like serum AST, ALT, ALP and lipid profile. Gene expression study was carried out for the expression of antioxidant and inflammatory genes such as CAT, GPx and proinflammatory gene IL-6. Histopathology of liver was also studied with the help of H&E staining. RESULTS Ashvagandharishta was found organolepticaly acceptable with optimized physiochemical parameters. Withaferin-A and withanolide-A in Ashvagandharishta estimated as 0.3711, 0.7426 (%w/v), respectively. In the CCl4 induced hepato-toxicity model, Ashvagandharishta-2.31ml/kg dose showed significant decrease in elevated hepatic level of AST(p<0.001), ALT(p<0.01) and ALP(p<0.001). Both doses of Ashvagandharishta showed significant reduction of TG, Cholesterol, VLDL and LDL in serum, with corresponding reduction of (p<0.001) serum-HDL. Ashvagandharishta also showed increased serum protein (p<0.05) and albumin (p<0.01) with decrease in bilirubin (p<0.01). Additionally, Ashvagandharishta administration revealed up-regulation in antioxidant genes such as CAT and GPx in liver with concomitant down-regulation in proinflammatory IL-6gene (p<0.01). Histopathological parameters revealed restoration of normal tissue architecture by both doses of Ashvagandharishta. CONCLUSIONS Consortium of yeasts from Woodfordia fruticosa flowers showed better fermentation pattern for Ashvagandharishta produced with acceptable organoleptic properties. Hepatoprotection shown by Ashvagandharishta was mainly through prevention of oxidative damage. Up-regulation of CAT and GPx genes and corresponding down regulation of proinflammatory IL6 gene was revealed as possible mechanism of its action.

Abstract
AIM In this study polyphenols from pomegranate peel, and n-3 fatty acids with polyphenols from flax seed were evaluated for their anti depression properties in mice exposed to chronic mild stress (CMS). METHODS A total of 40 mice initially trained to consume 2% sucrose solution for 3 weeks were then divided into five groups of eight each. The first group was the normal control, the remaining four groups were exposed to CMS but were force fed with either: 10 mL water per kg bodyweight per day; imipramine (a standard antidepressant) 15 mg kg bodyweight; 30 mg per kg bodyweight polyphenol equivalent extract from pomegranate peel; or 30 mg polyphenols per kg bodyweight with omega-3 fatty acids present, for 50 days. At the end, blood and brain were analyzed for various biomarkers of depression. RESULTS The flax seed and imipramine groups had significantly increased sucrose consumption, decreased cortisol (blood), decreased epinephrine and norepinephrine concentration, decreased monoamine oxidase A and B activity, and decreased superoxide dismutase activity. Lipid peroxidation was completely inhibited. In contrast, pomegranate peel extract also completely inhibited lipid peroxidation in the brain, and reduced enzyme activity and hormone concentration but to a lesser extent than flax seed. CONCLUSION Polyphenols from flax seed with omega-3 fatty acids were able to reduce all the CMS effects tested compared to polyphenols from pomegranate peel.

Abstract
The transformation of byproducts and wastes generated by agro-food companies is of high importance since only a small portion of plant material is utilized directly for human consumption. Squash pumpkin is greatly used in Portugal and as by-products of its processing are generated tons of shell and seeds. In this study we aim to evaluate the potential of these wastes as sources of beneficial and bioactive compounds (antioxidants and antimicrobials), studying the effect of different extraction solvents and drying methods. The samples (fresh and cooked) were freeze-dried and oven-dried followed by extraction with different solvents that revealed the following decreasing order of efficiency: 70 % ethanol, 70 % methanol, 70 % acetone, ultra-pure water and 100 % dichloromethane. The oven-dried samples showed higher values of antioxidant activity and phenolic content, with exception of the values of phenolics for the seeds material. The shell samples presented higher values (1.47 - 70.96 % inhibition) of antioxidant activity and total phenolic content (2.00 - 10.69 mg GAE/g DW). A positive correlation was found between these two parameters on the shell samples, however the squash seeds revealed a negative correlation between the phenolic content and the antioxidant activity. The results show that these industrial agro-food residues are potentially good sources of bioactive compounds with health benefits.
