- چکیده:
- چکیده انگلیسی: Objective(s): Various beneficial effects of curcumin have been seen specially as anti-inflammator and antioxidant agent. However, until now no human studies have been done on curcumin’s role in control of appetite. So, the present study was done to determine the effect of nanocurcumin on appetite in obese Non-Alcoholic Fatty Liver Disease (NAFLD) patients.
Materials and Methods: This study was done in the central hospital of Oil Company, Tehran. According to the eligiblity criteria, 84 NAFLD patients with obesity were enrolled. The patients were devided randomly to 2 equal groups (nanocurcumin and placebo, 80 mg/day with meals, follow-up monthly for 3 months). In addition, lifestyle advises were presented. The general questionnaire, appetite sensations (using visual analogue scales [VAS]), , weight and height at the beginning and the end of the study were recorded
Results: The mean age and body mass index (BMI) were 41.8(±5.6), 30.67(±2.14)and 42.5(±6.2)yrs and 30.75(±2.35)kg/m2 for nanocurcumin and placebo groups respectively. The baseline characteristics and dietary intakes were similar between patients, exception for energy, total fat, saturated fat, monounsaturated fatty acid, vitamins D, B1, B6, and folate (DFE). The appetite significantly reduced according to both unadjusted and adjusted analysis models.
Conclusion: This study was the first assess of nanocurcumin’s role in control of appetite among obese NAFLD patients. Overall results showed the nanocurcumin supplementation reduced appetite significantly. However, determining the potential role of curcumin in managing of NAFLD- and obesity-related conditions need further study.- انتشار مقاله: 09-11-1396

- چکیده:
- چکیده انگلیسی: Conventional transdermal drug delivery systems (TDDS) have been designed for drug delivery through the skin. These systems use the permeability property of stratum corneum, the outermost surface layer of the skin. Applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofibers fabrication with a great potential for drug delivery. More studies in the field of nanofibers containing drug are divided two categories: first, preparation and characterization of nanofibers containing drug and second, investigation of their therapeutic applications. Drugs used in electrospun nanofibers can be categorized into three main groups, including antibiotics and antimicrobial agents, anti-inflammatory agents and vitamins with therapeutic applications. In this paper, we review the application of electrospun polymeric scaffolds in TDDS and also introduce several pharmaceutical and therapeutic agents which have been used in polymer nanofibrous patches.

- چکیده:
- چکیده انگلیسی: Objective (s): The anti-fibrotic effect of chronic berberine (BBR) had demonstrated previously in a rat model of bile duct ligation (BDL). The aim of present study was to investigate hepatoprotective effect of BBR nanomicelles on liver cirrhosis induced by BDL in male rats.
Materials and methods: After 21 days of drugs’ treatments, the serum and tissue levels of hepatic markers were measured and pathologic evaluations performed.
Results: BDL could markedly increase aspartate aminotransferase (AST), alanine aminotransferase (ALT), LDH, and total bilirubin (TBIL) serum levels and tissue tumor necrosis factor-alpha (TNF-α) level along with reductions in tissue levels of key antioxidants glutathione (GSH) and superoxide dismutase (SOD) as well as total protein. On the other hand, silymarin (100 mg/kg, p.o.), BBR (100 mg/kg) and BBR nanomicelles (50 mg/kg, p.o.) markedly decreased AST and ALT while enhanced GSH. In addition, BBR nanomicelles (50 mg/kg, p.o.), silymarin (100 mg/kg, p.o.) and BBR (100 mg/kg, p.o.) groups showed a considerable increase in SOD. BBR nanomicelles (50 mg/kg, po.) significantly lowered TNF-α. In addition, nanoBBR treatment prevented liver cirrhosis in histopathologic analysis.
Conclusion: Formulation of BBR may represent a worthy approach to enhance the effect of it in liver injuries.- انتشار مقاله: 04-07-1397

- کلمات کلیدی: Bile duct-ligation, Cardiomyopathy, Nanoberberine,Rat, The NO- cGMP pathway
- چکیده:
- چکیده انگلیسی: Objective(s): In cirrhotic cardiomyopathy, a rise in pro-inflammatory cytokines results in the up-regulation of inducible nitric oxide synthase (iNOS), and the overproductions of nitric oxide (NO) and cyclic guanosine 3’, 5’ monophosphate (cGMP). Berberine (BBR), an isoquinoline-derived alkaloid isolated from Rhizoma coptidis, possesses anti-inflammatory, anti-oxidative, and cardioprotective properties. In this study, the effect of BBR-loaded micelles in a rat model of cirrhotic cardiomyopathy resulted from bile duct-ligation (BDL) was examined. Further, a possible role for NO-cGMP signaling was clarified.
Materials and Methods: Cirrhotic rats were orally treated with BBR-loaded micelles (50 mg/kg), free BBR (50 and 100 mg/kg) and silymarin (100 mg/kg). A selective iNOS inhibitor, aminoguanidine (AG) 100 mg/kg, i.p., was administered. iNOS expression and nitrite concentration were calculated using immunohistochemistry (IHC) and Griess reagent methods, respectively. Besides, ventricular tumor necrosis factor-alpha (TNF-α), cGMP, and serum interleukin -1beta (IL-1β) were measured using ELISA kits.
Results: TNF-α and IL-1β, nitrite, cGMP, and the expression of iNOS increased significantly in BDL rats. However, BBR (100 mg/kg), nanoBBR (50 mg/kg), and silymarin markedly lowered the levels of these markers. Notably, AG increased the nanoBBR effect.
Conclusion: This cardioprotective effect of nanoBBR probably mediated at least in part by down-regulations of the NO-cGMP pathway, and the inflammatory mediators.- انتشار مقاله: 28-04-1399

- چکیده:
- چکیده انگلیسی: In this study, the antioxidant activity and green synthesis of silver nanoparticles of ethanolic extracted from the seeds of Bunium persicum (Boiss.) B.Fedtsch was investigated for the first time. B.persicum is a local plant of Iran and the antioxidant activity of this plant was studied using the DPPH method and shows notable results in scavenging the free radicals. Antioxidant activity of extract checked in comparison to BHT.IC50 of B.persicum respectively was 1000mg/mL; revealing a notable antioxidant effect. Another experiment was performed on green synthesis of silver nanoparticles in this plant extract. Green synthesis of silver nanoparticles in B. persicum was confirmed by the Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM),UV-Vis spectroscopy, Energy dispersive X-ray diffraction analysis (EDX) and the X-ray diffraction (XRD). Ag NPs were almost spherical in shape, with an average diameter of 51 nm. Results showed significant antioxidant effects that cause the formation of spherical silver nanoparticles with nearly homological size in this plant and can be used as the basis of medical studies in the future.

- چکیده:
- چکیده انگلیسی: Abstract Background: Molecular imprinting is a method for synthesizing polymers with structure-selective adsorption properties with applications such as, selectivity binding, drug delivery systems and anti-bodies. The present study aims at optimizing the preparation of molecularly imprinted polymer (MIP) against l-phenylalanine, in order to increase phenylalanine-binding in Enzymatic Intestinal Simulated Fluid (ESIF). Methods: The MIP for l-phenylalanine, as a water-soluble template, was successfully synthesized without derivatization. Synthesization was done by a UV polymerization method in which methacrylic acid (MAA), as a functional monomer, and ethylene glycol dimethacrylate (EGDMA), as a cross-linker, were used in the presence of five different porogenic solvents including; acetonitrile, tetrahydrofuran (THF), chloroform, toluene and dimethyl sulfoxide (DMSO). The selectivity of the MIP was examined using 19 different amino acids in human serum and was evaluated by HPLC. In addition, morphological studies were conducted using SEM. Results: The results showed that the obtained MIP with acetonitrile had the highest capacity and selectivity compared with other solvents. The data indicated that Phe-binding to MIP was significantly more than the former binding to NIP in EISF (P≤0.05). Moreover, in comparison with NIP and control group, MIP showed a better selectivity and binding for Phe. This could be used for the reduction of Phe in human serum samples of Phenylketonuria.Conclusion: Our findings suggest that the MIP against Phe prepared with acetonitrile, showed a good selectivity and binding, which caused a reduction of blood Phe concentration in enzymatic simulated intestinal fluid and human serum sample of Phenylketonuria.

- چکیده:
- چکیده انگلیسی: Objective(s): An increase in nitric oxide (NO) production has been reported in cirrhotic cardiomyopathy and, portal hypertension. Since minocycline has been shown to inhibit NO overproduction, we aimed to examine its role in a rat model of CCl4-induced cirrhotic cardiovascular complications. Materials and Methods: Portal pressure and inotropic responsiveness of isolated papillary muscles to isoproterenol were measured in cirrhotic rats, following minocycline (50 mg/kg/day for 8 weeks) treatment. Moreover, isolated papillary muscles were incubated with nonselective and selective nitric oxide synthase (NOS) inhibitors, N (ω)-nitro-L-arginine methyl ester (L-NAME) and aminoguanidine (AG) respectively, in an organ bath. Ventricular expression and localization of inducible NOS (iNOS), tumor necrosis factor-alpha (TNF-α) and serum nitrite concentration were evaluated. Results: We found a decreased portal hypertension in minocycline-treated cirrhotic rats. Cirrhosis decreased contractility in response to isoproterenol stimulation, which was significantly attenuated by minocycline. Incubation with either L-NAME or AG reversed the impaired contractility in cirrhotic rats. Furthermore, minocycline decreased iNOS expression and localization in cardiomyocytes. A drop in serum nitrite and cardiac TNF-α level were also observed in cirrhotic rat that were treated by minocycline. Conclusion: The results suggest that minocycline may improve impaired cardiac contractility and hyperdynamic state in cirrhotic rats, and this effect could be mediated by NO-dependent mechanism.
