Background: Nesfatin-1 is a protein derived from a precursor molecule of the nucleobindin-2 gene, and acts as an anorexigenic peptide on food intake behavior, and its level isinfluenced by nutritional status, food composition [fat and carbohydrate (CHO)], and physical exercise. Objectives: The aim of this study was to investigate the effects of 6 weeks of treadmill running (at high intensity) program with and without zizyphus jujuba (high carbohydrate content) crud extraction on liver nesfatin-1, ATP, glycogen, and its plasma concentrations in female rats. Materials and Methods: Twenty-eight Wistar female rats (6-8 weeks old100-120 g of weight) were randomly assigned to saline-control (SC), saline-training (ST), zizyphus jujuba-control (ZJC), and zizyphus jujuba-training (ZJT) groups. Rats ran on a motor-driven treadmill at 35 m/min, 60 min/day, 5 days/week for 6 weeks. Animals received ZJ extraction and saline at the dose of 1.25 mL/100g of body weight. Seventy-two hours after the last training session rats were killed, a portion of liver excited, and plasma was collected for nesfatin-1, ATP, and glycogen measurements. A one-way ANOVA method, and Pearson correlation were employed. P < 0.05 was considered as significant. Results: A higher and significant liver nesfatin-1 level was found in ZJ groups (p < 0.005), but plasma nesfatin-1 responded differently. Changes in liver nesfatin-1 were accompanied with an increase in liver glycogen, but not ATP contents. Conclusions: The Findings indicate that higher liver nesfatin-1 and glycogen content by ZJ extraction might be due to the ZJ high CHO content, and it could be consideredas an anti-appetite herb. © 2013, Research Institute For Endocrine Sciences and Iran Endocrine Society.

The homotopy perturbation method (HPM) has been applied for the solving nonlinear differential equations of quantum dots (QDs). However, the HPM just gives the QDs behavior inside thick dielectric barriers as well as islands with deep quantum wells. In this paper, we apply a new approach which is based on modified homotopy perturbation method (MHPM) with self limiting model (SLM) to investigate the QDs behavior inside islands between clusters of sample surface. The MHPM and SLM are very effective, convenient and quite accurate to systems of partial differential equations and deal with nonlinearities distribution of the nonlinear differential equation. By using this method, we can find the exact solution of the QDs problem inside the islands. © 2012 Springer Science+Business Media, LLC.
