Abstract
BACKGROUND Vaspin is an adipocytokine with insulin-sensitizing and anti-inflammatory traits. OBJECTIVES The purpose of this study was to evaluate the effect of high-intensity interval training (HIIT) on serum, visceral and subcutaneous adipose tissue vaspin levels in rats exposed to a diet high in fat and sugar (HFS). MATERIALS AND METHODS Thirty-two male Wistar rats were randomly divided into HFS and standard diet (SD) groups. After 12 weeks, each group was divided into sedentary and HIIT groups. HIIT program was performed 3 times/week for 8 weeks. Retroperitoneal adipose tissue, inguinal adipose tissue and serum were collected to analyze vaspin levels. Also, serum glucose and insulin levels, insulin resistance index (HOMA-IR) and retroperitoneal and inguinal fat weights were measured. RESULTS HFS significantly increased weight gain, weight of inguinal (p=0.001) and retroperitoneal fat depots (p<0.001), serum glucose levels (p<0.001) and HOMA-IR (p<0.001). The HIIT was able to decline weight gain and fat mass (p<0.05) but did not affect inguinal and retroperitoneal fat depots' vaspin levels. Eight weeks' HIIT significantly increased serum vaspin (p=0.002) and decreased insulin (p=0.001) levels only in rats fed with SD. CONCLUSIONS Although the HIIT program can cause significantly reducing effects on weight gain and fat depots' weights, it does not effect on circulating and fat depots' vaspin levels in rats fed an HFS.

Abstract
Objectives Adansonia digitata L. is popularly known for the management of various neurological diseases in ethno-medicine. Studies have shown that lead toxicity is a possible risk factor for early onset of neurodegenerative disease. Hence, this study was designed to evaluate the effect of A. digitata aqueous leaf extract (ADALE) against lead-induced oxidative stress and histo-architectural changes in the prefrontal cortex of adult Wistar rats. Methods Saline (10 mL/kg), ADALE (500 and 1000 mg/kg) and EDTA (55 mg/kg) were pretreated orally 30 min prior to lead acetate (LA) (120 mg/kg) administration to male Wistar rats (n=7) for 21 days. Thereafter, standard biochemical (superoxide dismutate, catalase, glutathionxe and malondialdehyde), histological (H&E) and histochemical assessment (crystyl fast violet stain for nissil substance) were carried out in the prefrontal cortex. Results ADALE significantly (p<0.05) reversed LA-induced oxidative stress, as evidenced by increased catalase, superoxide dismutase and oxidized glutathione levels, and decreased malondialdehyde concentration in the prefrontal cortex. Also, the increase chromatolysis and neuronal pyknosis of the pyramidal neurons of the prefrontal cortex were significantly attenuated by ADALE. Conclusions The result of this study showed that A. digitata aqueous leaf extract attenuated lead acetate-induced cortical neurodegeneration via inhibition of oxidative stress.

Protective effect of Rumenic acid rich cow's milk against colitis is associated with the activation of Nrf2 pathway in a murine model. Prostaglandins Leukot Essent Fatty Acids 2017; 125:14-23. [PMID: 28987717 DOI: 10.1016/j.plefa.2017.08.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2017] [Revised: 07/06/2017] [Accepted: 08/21/2017] [Indexed: 12/27/2022]
Abstract
Dietary supplementation with pure cis9, trans11 isomer of Conjugated Linoleic Acid -known as Rumenic Acid (RA)- improves cytoprotective defenses downstream through the activation of nuclear factor-E2-related factor-2(Nrf2). This capability, when Rumenic Acid is consumed in the form of foods, is still unknown. The ability of standard (St) or cow milk naturally-enriched in RA (En) to activate Nrf2 pathway and its impact on dextran sodium sulfate (DSS)-induced colitis was comparatively evaluated. Activity of Nrf2 pathway was investigated in colonic tissue of BALB/c mice, receiving 4-week supplement with skimmed milk (SK), St or St reinforced with pure RA (RSt) providing increasing RA dose (0, 124 or 404mg RA/kg-1 b.w, respectively). Next, the anti-oxidant/ anti-inflammatory effect produced by St or En treatment (383mg RA/kg-1 b.w.) was explored. Finally, macroscopic and histomorphologic features of colitis were evaluated in animals challenged with 5% (w/v) DSS, at the end of St or En treatment. Significant activation of Nrf2 pathway is associated with RSt and En intake (P<0.05), but not with SK or En treatment. En pre-treatment offers better protection, in comparison with St, against pro-oxidant, pro-inflammatory signs (P<0.01) and macroscopic signs triggered by DSS. It can be concluded that Nrf2 activation by higher RA amount contained in En is, at least in part, responsible for the improved protection associated with En intake against DSS-induced colitis.

Abstract
Methylglyoxal (MG) has been found to cause inflammation and insulin resistance in vitro and in vivo in recent studies. Resveratrol has been proposed as an effective treatment that helps lower the risk of developing complications of diabetes. To study the significance of glycosylation-related stress on the pathology of diabetes, the effects of resveratrol were examined in a mouse model of diabetes induced by MG. Resveratrol was given via oral gavage in MG-treated mice, and diabetes-related tests and markers were assessed using biochemical and immunohistochemical analyses. Treatment with resveratrol markedly improved blood glucose level from the oral glucose tolerance test and promoted nuclear factor erythroid 2-related factor-2 (Nrf2) phosphorylation (p < 0.05) in the pancreas of MG-treated mice. However, these effects were abolished by retinoic acid, Nrf2 inhibitor, in resveratrol and retinoic acid-treated and MG-induced mice. These findings support that resveratrol may be useful in the treatment of type-2 diabetes by protecting against pancreatic cell dysfunction.

Adaptive response activated by dietary cis9, trans11 conjugated linoleic acid prevents distinct signs of gliadin-induced enteropathy in mice. Eur J Nutr 2015; 55:729-740.

Abstract
PURPOSE The beneficial effects of conjugated linoleic acid (CLA) mixture (cis9, trans11, c9; trans10, cis12, t10) against gliadin-induced toxicity in HLA-DQ8-transgenic mice (DQ8) have been associated with improved duodenal cytoprotective mechanisms [nuclear factor-E2-related factor-2, Nrf2; acylpeptide hydrolase (APEH)/proteasome]. The present study was aimed at investigating the ability of individual CLA isomers to improve the efficacy of these defensive mechanisms and to protect against duodenal injury caused by the combined administration of gliadin and indomethacin (GI). METHODS Gluten-mediated enteropathy was induced in DQ8 mice by three intra-gastric administration of gliadin (20 mg kg(-1)/bw) and indomethacin (15 mg L(-1)) in drinking water for 10 days (GI). C9 or t10 CLA (520 mg kg(-1)/bw/day) were orally administered for 2 weeks. Pro-oxidant and toxic effects associated with GI treatment, anti-oxidant/detoxifying ability of c9 or t10-CLA and the protective effect induced by c9 pre-treatment (c9 + GI) were evaluated in DQ8 mice duodenum by combining enzymatic, immunoblotting, histological evaluation and quantitative real-time PCR assays. RESULTS GI treatment produces the time-dependent decline of the considered detoxifying mechanisms thus leading to pro-apoptotic and pro-oxidant effects. APEH/proteasome pathway was not markedly affected by individual CLA isomers, but duodenal redox status and activity/mRNA levels of Nrf2-activated enzymes were significantly improved by c9 administration. c9 pre-treatment protects against GI-mediated accumulation of oxidative stress markers, and histological examination reveals the increase of goblet cells number in mouse duodenum but induces only a partial recovery of APEH/proteasome activity. CONCLUSIONS The activation of and adaptive response by low doses of c9 supplementation prevents distinct signs of gliadin-induced enteropathy in DQ8 mice.

Abstract
Lead (Pb) is considered to be a multi-target toxicant. The present study was undertaken to evaluate the protective effect of aqueous extract of Corchorus olitorius leaves against Pb-acetate induced toxic manifestation in blood, liver, kidney, brain and heart of Wistar rats. The Pb-acetate (5mg/kg body weight) treated rats exhibited a significant inhibition of co-enzymes Q, antioxidant enzymes and reduced glutathione levels in the tissues. In addition, the extent of lipid peroxidation, DNA fragmentation and haematological parameters were significantly altered in the Pb-acetate treated rats as compared to control. Simultaneous administration of test extract (25, 50 and 100mg/kg body weight), could significantly restore the biochemical and haematological parameters near to the normal status through antioxidant activity and/or by preventing bioaccumulation of Pb within the tissues of experimental rats. Presence of substantial quantity of phenolics and flavonoids in the extract may be responsible for the observed protective role against Pb-intoxication.
