Brain-targeted Tet-1 peptide-PLGA nanoparticles for berberine delivery against STZ-induced Alzheimer's disease in a rat model: Alleviation of hippocampal synaptic dysfunction, Tau pathology, and amyloidogenesis. Int J Pharm 2024; 658:124218. [PMID: 38734273 DOI: 10.1016/j.ijpharm.2024.124218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 05/06/2024] [Accepted: 05/08/2024] [Indexed: 05/13/2024]
Abstract
Alzheimer's disease (AD) is an age-related neurodegenerative disorder that causes severe dementia and memory loss. Surface functionalized poly(lactic-co-glycolic acid) nanoparticles have been reported for better transport through the blood-brain barrier for AD therapy. This study investigated the improved therapeutic potential of berberine-loaded poly(lactic-co-glycolic acid)/Tet-1 peptide nanoparticles (BBR/PLGA-Tet NPs) in a rat model of sporadic AD. BBR was loaded into the PLGA-Tet conjugate. BBR/PLGA-Tet NPs were physicochemically and morphologically characterized. AD was achieved by bilateral intracerebroventricular (ICV) injection of streptozotocin (STZ). Cognitively impaired rats were divided into STZ, STZ + BBR, STZ + BBR/PLGA-Tet NPs, and STZ + PLGA-Tet NPs groups. Cognitive improvement was assessed using the Morris Water Maze. Brain acetylcholinesterase and monoamine oxidase activities, amyloid β42 (Aβ42), and brain glycemic markers were estimated. Further, hippocampal neuroplasticity (BDNF, pCREB, and pERK/ERK), Tau pathogenesis (pGSK3β/GSK3β, Cdk5, and pTau), inflammatory, and apoptotic markers were evaluated. Finally, histopathological changes were monitored. ICV-STZ injection produces AD-like pathologies evidenced by Aβ42 deposition, Tau hyperphosphorylation, impaired insulin signaling and neuroplasticity, and neuroinflammation. BBR and BBR/PLGA-Tet NPs attenuated STZ-induced hippocampal damage, enhanced cognitive performance, and reduced Aβ42, Tau phosphorylation, and proinflammatory responses. BBR/PLGA-Tet NPs restored neuroplasticity, cholinergic, and monoaminergic function, which are critical for cognition and brain function. BBR/PLGA-Tet NPs may have superior therapeutic potential in alleviating sporadic AD than free BBR due to their bioavailability, absorption, and brain uptake.

Vitamin E (α-Tocopherol) Does Not Ameliorate the Toxic Effect of Bisphenol S on the Metabolic Analytes and Pancreas Histoarchitecture of Diabetic Rats. TOXICS 2023; 11:626. [PMID: 37505591 PMCID: PMC10383361 DOI: 10.3390/toxics11070626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 07/07/2023] [Accepted: 07/14/2023] [Indexed: 07/29/2023]
Abstract
This study investigated whether the coadministration of vitamin E (VitE) diminishes the harmful effects provoked by plasticizer bisphenol S (BPS) in the serum metabolites related to hepatic and renal metabolism, as well as the endocrine pancreatic function in diabetic male Wistar rats. Rats were divided into five groups (n = 5-6); the first group was healthy rats (Ctrl group). The other four groups were diabetic rats induced with 45 mg/kg bw of streptozotocin: Ctrl-D (diabetic control); VitE-D (100 mg/kg bw/d of VitE); BPS-D (100 mg/kg bw/d of BPS); The animals from the VitE + BPS-D group were administered 100 mg/kg bw/d of VitE + 100 mg/kg bw/d of BPS. All compounds were administered orally for 30 days. Body weight, biochemical assays, urinalysis, glucose tolerance test, pancreas histopathology, proximate chemical analysis in feces, and the activity of antioxidants in rat serum were assessed. The coadministration of VitE + BPS produced weight losses, increases in 14 serum analytes, and degeneration in the pancreas. Therefore, the VitE + BPS coadministration did not have a protective effect versus the harmful impact of BPS or the diabetic metabolic state; on the contrary, it partially aggravated the damage produced by the BPS. VitE is likely to have an additive effect on the toxicity of BPS.

Biochemical Changes Induced by the Administration of Cannabis sativa Seeds in Diabetic Wistar Rats. Nutrients 2023; 15:2944. [PMID: 37447270 DOI: 10.3390/nu15132944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 06/23/2023] [Accepted: 06/27/2023] [Indexed: 07/15/2023] Open
Abstract
The present pilot study investigates the blood biochemical changes induced by hemp seeds in rats with diabetes. The composition of industrial hemp seeds, antioxidant activity, identification and quantification of phenols and fatty acids from hemp oil were determined. The Wistar adult rats used in the experiment were divided into three groups (n = 6) and kept under standard conditions. Group one, the control group (individuals without diabetes), and group two (diabetic individuals) received water and normal food ad libitum, while the third group, also including diabetic individuals, received specific food (hemp seeds) and water ad libitum. Subsequent blood biochemical parameters were determined. Hemp seeds had higher phenol (14 compounds), flavonoids and PUFA contents compared to other plants seeds. In addition, the antioxidant activity in Cannabis sativa was also increased. Moreover, the ratio between n-6 and n-3 was 4.41, ideal for different diseases. Additionally, all biochemical parameters showed significant changes following the treatment. It was shown that high doses of hemp seeds decreased diabetes-induced biochemical damage in rats most probably due to the high content of active compounds. In order to use these seeds in humans, it is essential to find out which hemp compounds are particularly responsible for these effects. Moreover, for the objective investigation of their effects, longer-term studies are needed.

J Diabetes Metab Disord 2023; 22:571-580. [PMID: 37255789 PMCID: PMC10225424 DOI: 10.1007/s40200-022-01177-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 12/25/2022] [Indexed: 06/01/2023]
Abstract
Purpose The study was undertaken to evaluate the anti-diabetic potential of p-propoxybenzoic acid (p-PBA). Methods 36 Sprague-Dawley rats of either sex were utilized for the study. Animals were injected with nicotinamide (230 mg/kg) followed by streptozotocin (65 mg/kg) to induce Type-2 Diabetes (T2DM). Animals with blood glucose levels (BGL) over 200 mg/kg were allocated in six groups. Three groups were treated with p-PBA dose of 100 mg/kg, 200 mg/kg and 300 mg/kg respectively; standard control group was treated with 5 mg/kg glibenclamide, while the other two groups were considered as normal control and disease control group. Body weight (BW) and BGL were recorded on Day 0, Day 7, Day 14, and Day 28. Glycosylated hemoglobin (HbA1c), serum insulin levels and lipid profile were recorded on Day 28. Animals were euthanized on Day 28 and the pancreas was isolated for histopathological examination. Results Diabetic animals treated with p-PBA showed significant improvements in BW (P < 0.05) and BGL (P < 0.001) over 28 days. Levels of HbA1c (P < 0.05) and serum insulin (P < 0.001) were significantly regulated in animals treated with p-PBA. A significant decrease (P < 0.001) was observed in elevated levels of TC, TG, LDL cholesterol and VLDL cholesterol in animals treated with p-PBA. p-PBA significantly regulated the levels of HDL cholesterol (P < 0.001). A notable protective effect of p-PBA was observed through the histopathological examination of pancreas. Conclusion p-PBA can be characterized as a multi-target inhibiting anti-diabetic agent which can be evaluated against diabetic complications.

Abstract
This study was aimed to investigate the effect of Guisangyou tea (GSY tea) in improving abnormal lipid metabolism in mice with obesity induced by a high-fat diet (HFD). The results showed that intervention of the water extract of GSY tea (WE) decreased serum levels of lipids, and positively regulated the related antioxidant enzyme activities and the inflammatory factors in the serum and liver. In the liver, the mRNA and protein expression levels of sterol regulatory element-binding proteins-1 (SREBP-1), stearoyl-CoA desaturase-1 (SCD-1), fatty acid synthase (FASN), and acetyl CoA carboxylase (ACC) related to lipid synthesis were downregulated, and the mRNA and protein expression levels of the farnesoid X receptor (FXR) and small heterodimer partner (SHP) related to bile acid production were upregulated. The results demonstrate that GSY tea can improve abnormal lipid metabolism in obese mice by improving the body's antioxidant capacity, regulating the inflammatory state, and reducing the synthesis of lipids and increasing the production of bile acids. GSY tea can be processed and utilized as a safe and effective resource for improving abnormal lipid metabolism.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Natural herbs are gradually gaining recognition for their efficacy and safety in preventing diabetes and improving quality of life. Morus alba L. is a plant widely grown in Asia and is a traditional Chinese herb with a long history of use. Furthermore, several parts of Morus alba L. have been found to have significant health benefits. In particular, mulberry (Morus alba L.) leaves (ML) have been shown in human and animal studies to be promising hypoglycemic agents that can reduce or prevent glucolipid metabolism disorders caused by imbalances in the gut microbiota, inflammation, and oxidative stress and have demonstrated significant improvements in glucose metabolism-related markers, effectively lowering blood glucose, and reducing hyperglycemia-induced target organ damage. AIM OF THE STUDY This review briefly summarizes the methods for obtaining ML's bioactive components, elaborates on the clinical potential of the relevant components in managing type 2 diabetes mellitus (T2DM), and focuses on the therapeutic mechanisms of gut microbiota, inflammation, oxidative stress, and metabolism, to provide more inspiration and directions for future research in the field of traditional natural plants for the management of T2DM and its complications. MATERIALS AND METHODS Research on ML and its bioactive components was mainly performed using electronic databases, including PubMed, Google Scholar, and ScienceNet, to ensure the review's quality. In addition, master's and doctoral theses and ancient documents were consulted. RESULTS In clinical studies, we found that ML could effectively reduce blood glucose, glycated hemoglobin, and homeostasis model assessment of insulin resistance in T2DM patients. Furthermore, many in vitro and in vivo experiments have found that ML is involved in various pathways that regulate glucolipid metabolism and resist diabetes while alleviating liver and kidney damage. CONCLUSIONS As a potential natural anti-diabetic phytomedicine, an in-depth study of ML can provide new ideas and valuable references for applying traditional Chinese medicine to treat T2DM. While continuously exploring its clinical efficacy and therapeutic mechanism, the extraction method should be optimized to improve the efficacy of the bioactive components. in addition, further research on the dose-response relationship of drugs to determine the effective dose range is required.

[PMID: 36544524 PMCID: PMC9742567 DOI: 10.22038/ijbms.2022.65646.14441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 10/22/2022] [Indexed: 12/24/2022]
Abstract
Objectives In this study, to find scientific evidence for the traditional use of Pergularia tomentosa as an anti-diabetic remedy, the effects of its aqueous extract on streptozotocin-induced diabetes mellitus in rats were evaluated. Materials and Methods Wistar rats were fasted overnight and diabetes mellitus was induced using streptozotocin (50 mg/kg body weight). The rats were randomly and equally divided into four groups (n=5): group I (normoglycaemic control), group II (diabetic rats), group III (diabetic rats treated with 200 mg/kg BW of an aqueous extract of P. tomentosa), group IV (normoglycemic rats treated with 200 mg/kg BW of an aqueous extract of P. tomentosa). Chemical profiling of the aqueous extract was carried out using liquid chromatography coupled with electrospray ionization and multiple-stage linear ion-trap and orbitrap high-resolution mass spectrometry (LC-ESI/LTQOrbitrap/MS/MS). In addition, the quantitative determination of the main cardenolides in the extract was carried out by an analytical approach based on LC coupled to tandem mass spectrometry with ESI source and hybrid triple quadrupole-linear ion trap mass analyzer (LC-ESI/QTrap/MS/MS). Results Aqueous extract of P. tomentosa showed a reasonable reduction in blood glucose level. Probably, the P. tomentosa effect on hyperglycemic and hyperlipidemic diabetic animals was associated with antioxidant properties, triglyceride levels, as well as liver enzymes. Meanwhile, LC-ESI/LTQOrbitrap/MS/MS analysis led to identification of double-linked cardenolides along with cardenolides and flavone glycosides as the main bioactive compounds. Conclusion The extract decreased the glucose level and induced a beneficial effect on the lipid profile, probably due to the presence of cardenolide glycosides.

Abstract
Objective:Spondias mombin is a plant that reported to have anticonvulsant, antimicrobial, antioxidant, antiulcer, antiasthmatic, and wound healing activities. Diabetes dyslipidemic effect of Spondias mombin leaves is not clear. Hence, current study planned to evaluate the antidiabetic and antihyperlipidemic effects of methanolic extract of leaves of Spondias mombin (MESM) in streptozotocin (STZ) induced diabetic rats. Methods: Phytochemicals were determined by standard method and antioxidant activity was determined by DPPH free radical scavenging and FRAP assay. Diabetes was induced by injecting a single dose of STZ (55 mg/kg) into female sprague dawley rats. After 3 days of induction of diabetes, the diabetic animals were treated for 28 days with MESM (125, 250, and 500 mg/kg) and glibenclamide (20 mg/kg) orally. The body weight of rats and blood glucose levels were monitored at regular intervals during the experiment. At the end of study, blood sample was collected from all the animals and subjected to biochemical, lipid profile, and they were sacrificed and their organs such as pancreas, liver and kidney were used for histopathological analysis. Results: Quantitative analysis of MESM showed the presence of anthraquinone, tannins, saponins, steroid, phenols, flavonoids, alkaloids, and reducing sugars. Reduction in body weight and elevated blood glucose were observed in diabetic rats. Treatment with MESM in a concentration of 125, 250, and 500 mg/kg significantly reversed the elevated levels of blood glucose, reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin, urea, creatinine, total serum cholesterol (TC), serum triglyceride (TG), low-density lipoprotein (LDL), Very low-density lipoprotein (VLDL), and increased plasma insulin, total protein, albumin, globulin, A/G ratio, and high-density lipoprotein (HDL). Conclusion: MESM exhibited a significant antidiabetic and antihyperlipidemic activities against STZ-induced diabetes in rats.

Abstract
Prebiotics, gut microbiota-fermentable substances, delay the development of type I diabetes. In the present study, we investigated the effect of two prebiotics (galacto-oligosaccharides and xylo-oligosaccharides) on the antioxidant protection, lipid profile, and inflammatory activity of rats with streptozotocin-induced diabetes. The following markers were studied - malondialdehyde, 8-hydroxy-2'-deoxyguanosine, ferric reducing ability of plasma (FRAP), triacylglycerols, total cholesterol (TC), high-density lipoproteins, C-reactive protein (CRP), and interleukin-6. Diabetes was induced in male Wistar experimental rats by streptozotocin injection, while the non-diabetic controls were injected with saline. Afterward the oligosaccharides were administered orally to the experimental animals. The blood collected following the decapitation was analyzed by ELISA. A modified protocol was used only for measuring the FRAP values. The galacto-oligosaccharides and xylo-oligosaccharides lowered the malondialdehyde levels in the diabetic rats (p < 0.05). The galacto-oligosaccharides decreased the serum levels of 8-hydroxy-2'-deoxyguanosine (p = 0.01), while the xylo-oligosaccharides increased the FRAP (p < 0.05) in the experimental animals. None of the oligosaccharides affected triacylglycerol and interleukin-6 concentrations, but the galacto-oligosaccharides decreased the TC and CRP levels in the diabetic animals. Both oligosaccharides exert a beneficial effect on the antioxidant protection of the diabetic rats, but have a minor effect on their lipid and inflammatory profiles.

Abstract
Abstract
Background
Changes in blood lipid level (dyslipidemia) play a central role in the onset and pathogenesis of macrovascular complications of diabetes mellitus. Traditional herbal healers commonly use anti-diabetic polyherbal formulations to provide a multi-therapeutic approach for the treatment of diabetes mellitus and its associated complications. The effect of the aqueous leaf extracts of Leptadenia hastata (pers) Decne, Momordica balsamina Linn and their combination on lipid profile of streptozotocin (STZ)-induced diabetic rats was therefore evaluated in the present study.
Results
We evaluated the serum lipid profile and blood glucose level of STZ-induced diabetic rats (60 mg/kg body weight) treated with the aqueous leaf extracts of L. hastata (400 mg/kg) and M. balsamina (200 mg/kg) alone and in combination (400 + 200 mg/kg) after a period of 4 weeks. A significantly decreased (p < 0.05) level of total cholesterol (TC), triglyceride (TG), very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) cholesterol levels and increased (p < 0.05) level of high-density lipoprotein (HDL) cholesterol was observed in all the treated groups when compared to the untreated diabetic rats. Furthermore, the combination treatment was potentially a more effective blood lipid-lowering (p < 0.05) agent when compared to the single treatments.
Conclusion
Results from this study demonstrated the blood lipid-lowering potential of the aqueous leaf extracts of L. hastata, M. balsamina, and their combination. However, the polyherbal combination could be more potent in controlling diabetes mellitus, associated dyslipidemia, and its complications.

Abstract
Diabetes mellitus or type-2 diabetes, commonly referred as diabetes, is a metabolic disorder that results in high blood sugar level. Despite the availability of several antidiabetic drugs in the market, they still do not adequately regulate blood sugar levels. Thus, in general people prefer to use herbal supplements/medicines along with antidiabetic drugs to control blood sugar levels. One of such herbal medicine is Swietenia macrophylla seeds. It is widely used in Asia for controlling blood sugar levels. One of the major bioactive compounds, Swietenine, is reported to be responsible for controlling blood glucose levels. However, there were no studies on its efficacy in controlling the blood glucose in diabetic rats. In this study, we evaluated the antihyperglycemic activity of Swietenine and its pharmacodynamic interaction with Metformin in Streptozotocin induced diabetes in rats. The activity of Swietenine was investigated at three different doses: 10, 20 and 40 mg/kg body weight (bw). Metformin (50 mg/kg bw) was used as a standard drug. Swietenine (20 and 40 mg/kg bw) and Metformin (50 mg/kg bw) showed significant effect in reducing the glucose, cholesterol, triglycerides, low-density lipoprotein, urea, creatinine, alanine transaminase, alkaline phosphatase, aspartate transaminase, alanine transaminase, and malondialdehyde level in serum while it had increased the high-density lipoprotein, glutathione, and total antioxidant capacity level. In addition, Swietenine (20 and 40 mg/kg) had shown significant synergistic effect with Metformin. Administration of Swietenine at 10 mg/kg bw neither showed activity nor influenced Metformin's activity. The results from this study confirmed the beneficial effects of Swietenine and its synergistic action with Metformin in controlling the dysregulated serum parameters in Streptozotocin induced diabetes in rats.

Abstract
INTRODUCTION Hypoglycemia in diabetes mellitus (DM) correlates with hepatic impairment, nephropathy, lipid abnormalities, and oxidative stress and subsequently complicates the disease pathogenesis. Medicinal plants have been used for the management of diabetes since ancient times. In this study, we explored the potentials of Colocasia affinis (CA), a plant known to possess anti-allergic and anti-inflammatory activities, as a remedy for diabetes and related complications. METHODS We induced diabetes in rats using a single intraperitoneal dose (65 mg/kg) of streptozotocin (STZ). We next treated the rats with an ethanolic extract of leaves of CA to reveal its antidiabetic and organ-protective potentials. Biomarkers of diabetes, inflammation, and oxidative stress were measured using biochemical and histopathological analysis. We also performed molecular docking for three major phytochemicals (kaempferol, myricetin, and rosmarinic acid) of CA. RESULTS Oral administration of the CA leaves extract at 250 mg/kg and 500 mg/kg doses decreased blood glucose level significantly (p<0.05) in STZ-induced diabetic rats. The extract also considerably attenuated plasma HbA1c levels and normalized blood lipids, glycogen, alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Additionally, treatment with the extract improved kidney complications by decreasing serum creatinine and blood urea nitrogen (BUN) levels. Furthermore, CA leaves extract normalized nitric oxide (NO) and advance oxidative protein products (AOPP) in diabetic rats. The extract also showed significant improvement of the antioxidant enzymes glutathione dismutase (GSH) and superoxide dismutase (SOD) at a dose of 500 mg/kg. Besides, histological investigation demonstrated attenuation of inflammation of the vital organs, including the liver and the kidney. In silico studies revealed that three major phytochemicals (kaempferol, myricetin, and rosmarinic acid) of the ethanolic extract of leaves of CA can inhibit several molecular targets of diabetes and inflammation. CONCLUSION Collectively, our results demonstrated the therapeutic potentials of CA for the mitigation of diabetes and diabetic complications.

Abstract
Triterpenoids are well known modulators of metabolic syndrome. One of the suggested modes of action (MoAs) involves peroxisome proliferator-activated receptor gamma (PPARγ) binding. In this study we aimed to: (i) evaluate in silico potential metabolites and PPARγ-mediated MoA of the sapogenin of the main saponin present in a purified saponins' mixture (PSM) from Astragalus glycyphylloides; (ii) estimate in silico and in vivo PSM's toxicity; and (iii) investigate in vivo antihyperglycaemic, hypolipidaemic, antioxidant and hepatoprotective effects of PSM. Metabolites and toxicity were predicted using Meteor and Derek Nexus expert systems (Lhasa Limited) and PPARγ binding was investigated using the software MOE (CCG Inc.). PSM's acute oral toxicity was evaluated in mice and the pharmacological effects were assessed in streptozotocin-induced diabetic spontaneously hypertensive rats (SHRs). Liver histopathology was studied as well. PPARγ weak partial agonism was predicted in silico for 24 probable/plausible Phase I metabolites which docking poses were clustered in 12 different binding modes with characteristic protein-ligand interactions. PSM's beneficial effects on the levels of blood glucose, triglycerides, and total cholesterol, on oxidative stress markers and liver histology in diabetic SHRs were comparable to those of the PPARγ ligand pioglitazone. PSM's safety profile was confirmed in silico and in vivo.

Abstract
Background: Diabetes mellitus is associated with increased blood glucose and triglyceride levels, which can lead to an oxidative stress. Zinc (Zn) is a micronutrient that has antioxidant properties and involved in lipid and glucose metabolism. This study aimed to evaluate the effect of zinc on the levels of fasting blood glucose (FBG), triglycerides (TG), and malondialdehyde (MDA) in male diabetic Rattus norvegicus Wistar rats.Methods: Diabetes was induced by intraperitoneal (i.p.) injection of 40 mg/kg BW streptozotocin (STZ) and confirmed by FBG level higher than 200 mg/dL after 2 weeks. The rats were randomly divided into three groups: control group (STZ), treatment I (STZ + zinc 5 mg/kg BW), and treatment II (STZ + zinc 10 mg/kg BW). Zinc was administered by oral gavage for 30 days. At the end of the experiment, levels of FBG, TG, and MDA were measured. Data were analyzed using paired t-test or Wilcoxon test as appropriate.Results: Supplementation of 5 mg/kg zinc significantly decreased the levels of FBG (pre-intervention: 328.95±70.90 mg/dL, post-intervention: 144.35±34.27 mg/dL, p<0.05), TG (pre-intervention: 252.48±26.30 mg/dL, post-intervention: 147.90±12.18 mg/dL, p<0.05), and MDA (pre-intervention: 12.11±6.46 nm/mL, post-intervention: 4.75±2.34 nm/mL, p<0.05). Moreover, supplementation of 10 mg/kg zinc decreased the levels of TG (pre-intervention: 275.62±56.25nm/mL, post-intervention: 165.58±22.63 nm/mL, p<0.05) and MDA (pre-intervention: 13.08±6.60 nm/mL, post-intervention: 5.08±2.40 nm/mL, p<0.05).Conclusion: Supplementation of zinc significantly reduced the levels of FBG, TG, and MDA in diabetic rats.

Abstract
Diabetes mellitus is often associated with cardiac functional and structural alteration, an initial event leading to cardiovascular complications. Roselle (Hibiscus sabdariffa) has been widely proven as an antioxidant and recently has incited research interest for its potential in treating cardiovascular disease. Therefore, this study aimed to determine the cardioprotective effects of H. sabdariffa (roselle) polyphenol-rich extract (HPE) in type-1-induced diabetic rats. Twenty-four male Sprague-Dawley rats were randomized into 4 groups (n = 6/group): nondiabetic, diabetic alone (DM), diabetic supplemented with HPE (DM+HPE), and diabetic supplemented with metformin. Type-1 diabetes was induced with streptozotocin (55 mg/kg intraperitoneally). Rats were forced-fed with HPE (100 mg/kg) and metformin (150 mg/kg) daily for 8 weeks. Results showed that HPE supplementation improved hyperglycemia and dyslipidemia significantly (p < 0.05) in the DM+HPE compared with the DM group. HPE supplementation attenuated cardiac oxidative damage in the DM group, indicated by low malondialdehyde and advanced oxidation protein product. As for the antioxidant status, HPE significantly (p < 0.05) increased glutathione level, as well as catalase and superoxide dismutase 1 and 2 activities. These findings correlate with cardiac function, whereby left ventricle developed pressure in DM+HPE (79.13 ± 3.08 mm Hg) was higher significantly compared with DM (45.84 ± 1.65 mm Hg). Coronary flow of DM+HPE (17.43 ± 0.62 mL/min) was also greater compared with DM (13.02 ± 0.6 mL/min), showing that HPE supplementation improved cardiac contractility and relaxation rate significantly (p < 0.05). Histological analysis showed a marked decrease in cardiomyocyte hypertrophy and fibrosis in DM+HPE compared with the DM group. Ultrastructural changes and impairment of mitochondria induced by diabetes were minimized by HPE supplementation. Collectively, these findings suggest that HPE is a potential cardioprotective agent in a diabetic setting through its hypoglycemic, anti-hyperlipidemia, and antioxidant properties.

Abstract
α-glucosidase is an essential enzyme located at the brush border of intestines. It is an important therapeutic target for type II diabetes. Herein we have designed a library of novel α-arylketones as inhibitors of α-glucosidase (yeast origin) via scaffold hopping and bioisosteric modification of known inhibitors of α-glucosidase. The design was validated through molecular docking that revealed strong binding interactions of the newly designed compounds against α-glucosidase. A library comprising of 15 compounds was synthesized in a combinatorial fashion, where the advanced amide intermediates were accessed through “shot gun” synthesis. The final compounds were characterized by 1H, 13C-NMR and with high resolution mass spectroscopy. In vitro screening of the compounds against yeast α-glucosidase revealed substantial inhibition with IC50s in the range of 4–10 μM (the standard drug acarbose inhibits α-glucosidase with an IC50 of 9.95 μM). Reaction kinetics suggested mixed type inhibition. Finally, in vivo studies of the most active compound 3c against Streptozotocin induced male albino Wistar rats revealed that its administration in the rats for about 4 weeks lead to a highly significant (P < 0.001) decrease in the fasting blood glucose (FBG) compared to the untreated diabetic rats. Moreover, lower dose of 3c had better control over FBG in contrast to high-dose.

[PMID: 28595785 DOI: 10.1016/j.jtemb.2017.04.013] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2017] [Revised: 04/17/2017] [Accepted: 04/26/2017] [Indexed: 12/17/2022]
Abstract
The cardio-protective effects of zinc oxide nanoparticles (Zn NPs) against diabetes-induced cardiopathy were evaluated and compared with zinc sulfate (ZnSO4). A total of 120 Wistar rats were randomly categorized as healthy and diabetic groups. Then, the 2 groups were classified in 5 subgroups. The animals received oral supplementations containing different Zn NP (ie, doses of 1, 3, and 10mg/kg) and ZnSO4 (30mg/kg) concentrations over 8 weeks. Blood and cardiac tissue samples were collected in the different time intervals and subjected to biochemical and histopathological analysis. Zn NPs showed dual effects, as its middle dose played protective role and recovered cardiac damages evidenced by significant reduction of serum cholesterol, HDL-cholesterol, lipoprotein (a), atherogenic index, TNF-α, cardiac MDA, B-type natriuretic peptide and caspase-3 activity. Apoptosis indices and histopathological features also were improved. However, the highest dose was found to be toxic and resulted in aggravation of the injuries. Another interesting finding is the ability of the higher doses of Zn-NPs (3 and 10mg/kg) to elevate cardiac zinc levels above the normal range in healthy animal. ZnSO4 also helped to recuperation of the damages, but the middle dose of Zn NPs was more efficient as compared to ZnSO4. Conclusively, Zn NPs have the potential for Zn delivery in diabetic patients.

Abstract
BACKGROUND This study was designed to investigate the effects of immature carob pod aqueous extract (ICPAE) on intestinal glucose absorption in vitro and in vivo using an oral glucose tolerance test (OGTT) as well as the potential antidiabetic effect in alloxan-induced diabetic rats. OGTT was carried by administration of glucose (2 g kg-1 , p.o.) and after treatment with extract (50, 100 and 200 mg kg-1 body weight). Diabetes was induced by single intraperitoneal injection of alloxan (150 mg kg-1 ). However, the extracts at various doses or glibenclamide (GLB, 10 mg kg-1 body weight) were given by oral administration for 2 weeks. RESULTS ICPAE (50-2000 µg mL-1 ) exerted dose-dependent reduction of sodium-dependent glucose transport across isolated mice jejunum and the maximal inhibition exceeded 50%.The ICPAE treatment improved glucose tolerance. More importantly, ICPAE at various doses showed a significant reduction in blood glucose and biochemical profiles in diabetic rats. CONCLUSION Our findings confirm that the degree of maturity of carob characterized by a different phytochemical composition may be responsible for these actions. Therefore, these compounds may be used as a food supplement in hyperglycemia and diabetes treatments. © 2016 Society of Chemical Industry.

Abstract
Accumulating evidence suggested that inflammatory processes are involved in the development of diabetic nephropathy (DN). Here, we have tested the hypothesis that Caprylic Acid (Cy)-diacylglycerol (DAG) oil (Cy-DAG), a novel structurally formulated lipid with high nutritional value, ameliorated DN in streptozotocin (STZ)-induced diabetic rats through the anti-inflammatory mechanisms. Basic hematological, biochemical parameters, immunoblotting, immunofluorescence and flow cytometry analysis were performed to observe the anti-inflammatory potential of Cy-DAG oil. The data revealed that STZ significantly increased the renal oxidative stress markers and decreased the levels of renal enzymatic and non-enzymatic antioxidants. Moreover, renal nitric oxide (NO), tissue necrosis factor-α (TNF-α), interleukin-6 (IL-6) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) were also increased in the renal tissue of STZ-treated rats. Further, DAG oil pretreatment produced a significant improvement in renal antioxidant status, reduced the lipid peroxidation and the levels of inflammatory markers in STZ-treated kidney. Similarly, results of protein expression showed that DAG oil pretreatment normalized the renal expression of Nrf2/Keap1 and its downstream regulatory proteins in STZ-treated condition. Immunohistochemical observations provided further evidence that DAG oil effectively protected the kidney from STZ-mediated oxidative damage. These results suggested that the DAG oil ameliorated STZ-induced oxidative renal injury by the activation of AKT/Nrf2/HO-1 pathway and the inhibition of ROS/MAPK/NF-κB pathway.

Abstract
Lack of physical activity, smoking and/or inappropriate diet can contribute to the increase of oxidative stress, in turn affecting the pathophysiology of cardiovascular diseases. Strong anti-oxidant properties of plant polyphenolic compounds might underlie their cardioprotective activity. This paper reviews recent findings on the anti-oxidant activity of plant leaf extracts and emphasizes their effects on blood platelets, leukocytes and endothelial cells - the targets orchestrating the development and progression of cardiovascular diseases. We also review the evidence linking supplementation with plant leaf extracts and the risk factors defining the metabolic syndrome. The data point to the importance of leaves as an alternative source of polyphenolic compounds in the human diet and their role in the prevention of cardiovascular diseases.

Abstract
CONTEXT Antidesma bunius L (Phyllanthaceae) is commonly known to local people in North-east Thailand as a medicinal plant. OBJECTIVES To investigate hypoglycaemic activities of methanolic extract of A. bunius in type 1 diabetes. MATERIALS AND METHODS A daily dose of A. bunius extract (250 mg/kg body weight) was given orally to alloxan-induced diabetic rats for 28 days. Blood glucose, insulin, TC, TG, amylase, lipase, liver glycogen were analysed. RESULTS Extract revealed a significant reduction in blood glucose level (80.5%) along with an increase in serum insulin (134%), lipase (90.7%) and liver glycogen level (160%). Also amylase (28.2%) activity, TC (40.2%), and TG (28.8%) levels were significantly decreased when compared with diabetic control rats. A. bunius extract improved the histo-architectural of the β-cells. DISCUSSION AND CONCLUSION The results suggested that A. bunius extract possess anti-diabetic activity, through the enhancement of hepatic glycogen storage and regeneration of the islet of Langerhans.

Abstract
Diabetes mellitus is the most common endocrine disorder that affects more than 285 million people worldwide. The purpose of this study was to investigate the effect of mesenchymal stem cells (MSCs) from the bone marrow of albino rats, on hyperglycemia, hyperlipidemia, and oxidative stress induced by intraperitoneal injection (i.p.) of alloxan at a dose of 150 mg/kg in rats. Injection of alloxan into rats resulted in a significant increase in serum glucose, total cholesterol, triglyceride, low density lipoprotein cholesterol, and sialic acid level and a significant decrease in serum insulin, high density lipoprotein-cholesterol, vitamin E, and liver glycogen as compared to their corresponding controls. Also, oxidative stress was noticed in pancreatic tissue as evidenced by a significant decrease in glutathione level, superoxide dismutase, glutathione-S-transferase activities, also a significant increase in malondialdehyde and nitric oxide levels when compared to control group. Treatment of diabetic rats with MSCs stem cells significantly prevented these alterations and attenuated alloxan-induced oxidative stress. In conclusion, rat bone marrow harbors cells that have the capacity to differentiate into functional insulin-producing cells capable of controlling hyperglycemia, hyperlipidemia, and oxidative stress in diabetic rats. This may be helpful in the prevention of diabetic complications associated with oxidative stress.

Abstract
The present study was designed to examine the therapeutic potential of Terminalia arjuna bark extract in improving cardiovascular autonomic neuropathy in Streptozotocin (STZ)-induced diabetic Wistar Albino rats. The baroreflex was evaluated by measuring the changes in heart rate with changes in arterial blood pressure induced by bolus injections of phenylephrine (vasoconstrictor) and sodium nitroprusside (vasodilator). T. arjuna bark extract, Rosuvastatin and Insulin were tested/administered therapeutically in rat model of uncontrolled diabetes. After 8 weeks of STZ administration, the reflex bradycardia and tachycardia response to hypertension and hypotension, respectively, were impaired in the diabetic group. The reflex bradycardia improved significantly after 1 month treatment of T. arjuna while the reflex tachycardia could not improve. The decreased body weight, heart rate, blood pressure and raised blood sugar in diabetic rats were not improved by T. arjuna therapy. Rosuvastatin treatment exerted similar effects while Insulin improved all the parameters. Further T. arjuna, Rosuvastatin and Insulin significantly reduced oxidative stress and inflammatory cytokine levels in diabetic rats. Results suggest that T. arjuna bark extract improves the altered baroreflex sensitivity in diabetic rats possibly through maintaining endogenous antioxidant enzyme activities and decreasing cytokine levels.

Abstract
Diabetes mellitus (DM) is a significant risk factor for the development of cardiovascular complications. This study was undertaken to investigate the effect of chronic administration of ethanolic extract of Eryngium carlinae on glucose, creatinine, uric acid, total cholesterol, and triglycerides levels in serum of streptozotocin- (STZ-) induced diabetic rats. Triglycerides, total cholesterol, and uric acid levels increased in serum from diabetic rats. The treatment with E. carlinae prevented these changes. The administration of E. carlinae extract reduced the levels of creatinine, uric acid, total cholesterol, and triglycerides. Thus administration of E. carlinae is able to reduce hyperlipidemia related to the cardiovascular risk in diabetes mellitus.

Abstract
Natural remedies from medicinal plants are considered to be effective and safe alternative treatment for diabetes mellitus. The aim of the present study was to investigate the hypoglycemic activity of the crude tea leaves extract on streptozotocin (STZ)-induced diabetic mice. The average body weight of animals with diabetes and their percentage changes of body weight gain after 15 and 30 days were significantly lower than that of the normal control mice. In diabetic mice, supplementation with tea leaves extract decreased the loss of body weight. After 15 and 30 days, significant increases in the levels of serum glucose, triglycerides, cholesterol, creatinine, urea, uric acid, glutamic pyruvic acid transaminase (GPT) and glutamic oxaloacetic acid transaminase (GOT) were noted in STZ-diabetic mice fed with normal diet. Also, the values of total protein in this group were statistically declined after 15 and 30 days. The levels of serum glucose and GPT were significantly elevated after 15 and 30 days in diabetic mice supplemented with tea leaves extract. Moreover, the level of serum GOT was notably increased after 30 days. Insignificant alterations were observed in the levels of serum triglycerides, cholesterol, total protein, creatinine, urea and uric acid in diabetic mice supplemented with tea leaves extract. Thus, the present results have shown that tea leaves extract has the antihyperglycemic, antihyperlipidemic, and antihyperproteinemic effects and consequently may alleviate liver and kidney damage associated with STZ-induced diabetes in mice.
