Neurobiology of Learning and Memory | Year: 2010

Learning and memory deficits occur in diabetes mellitus. Although the pathogenesis of cognitive impairment in diabetes has not been fully elucidated, factors such as metabolic impairments, vascular complications and oxidative stress are thought to play possible roles. Here we investigated the effect of chronic treatment with vitamin C (50. mg/kg, p.o), vitamin E (100. mg/kg, p.o) and both together on passive avoidance learning (PAL) and memory in male Wistar control and diabetic rats. Treatments were begun at the onset of hyperglycemia. Passive avoidance learning was assessed 30. days later. Retention was tested 24. h after training. At the end, animals were weighed and blood samples were drawn for plasma glucose measurement. Diabetes caused impairment in acquisition and retrieval processes of PAL and memory. The combination of vitamin C and E improved learning and memory in controls and reversed learning and memory deficits in diabetic rats. Combined treatment also affected the body weight and plasma glucose level of diabetic treated animals compared to untreated diabetic animals. Hypoglycemic effects and antioxidant properties of the vitamins may be involved in the nootropic effect of such treatment. These results show that combined treatment with vitamins C and E improved PAL and memory of control rats. In addition, combined vitamins administration to rats for 30. days from onset of diabetes alleviated the negative influence of diabetes on learning and memory. Therefore, combined vitamins treatment may provide a new potential alternative for prevention of impaired cognitive functions associated with diabetes and may warrant further clinical study. © 2010 Elsevier Inc.

There is considerable interest in histamine H3 receptors as emerging pharmaceutical targets recently. Diabetic rats display increased pain responses following the injection of formalin into the paw suggesting the presence of hyperalgesia. In this study, the efficacy of systemic administration of selective H3 receptor agonist, immepip (1, 5 and 30 mg/kg), and antagonist, thioperamide (5, 15 and 30 mg/kg), was investigated on hyperalgesia during the formalin test in streptozocin (STZ)-induced diabetic rats. Nociceptive testing was performed in male adult Wistar rats 4 weeks after the onset of hyperglycemia. At the end of the experiment, all rats were weighed and then underwent plasma glucose measurement. Diabetes caused significant hyperalgesia during both phases of the formalin test. 5 and 30 mg/kg doses of immepip reversed chemical hyperalgesia in diabetic rats. The 1 mg dose of immepip did not alter pain behaviors in control and diabetic groups compared to the respective control ones. Immepip at any doses used in this study did not affect the body weight and plasma glucose levels of treated animals. Thioperamide alone at any doses used had no effect on formalin-induced nociceptive behaviors in the control and diabetic rats. The results indicated the efficacy of immepip systemic administration in an experimental model of diabetic hyperalgesia. It may also suggest it as a promising tool for treatment of painful diabetic neuropathy. © 2011 Elsevier Ltd. All rights reserved.

Composite Structures | Year: 2010

Three-dimensional thermo-elastic analysis of functionally graded (FG) rectangular plates with simply supported edges subjected to thermo-mechanical loads are carried out in this paper. The thermo-elastic constants of the plate were assumed to vary exponentially through the thickness, and the Poisson ratio was held constant. Analytical solutions for the temperature, stress and displacement fields are derived by using the Fourier series and state-space method. To verify the accuracy of the present work, a comparison is made with previously published results. The effects of temperature change, applied mechanical load, gradient index, aspect ratio and thickness to length ratio on the behavior of the plate are examined. © 2009 Elsevier Ltd.

This paper presents analytical solution for functionally graded material (FGM) beams integrated with piezoelectric actuator and sensor under an applied electric field and thermo-mechanical load. In FGM host properties is assumed to vary exponentially in thickness direction and the Poisson's ratio is held constant. The hybrid beam is in a state of plane stress and the piezoelectric is composed of orthotropic materials. The beam is simply supported with the bottom surface traction free and zero temperature. By using of state-space method in thickness direction and Fourier series in longitudinal direction, the solution can be made. To verify the accuracy of the present formulation, numerical results for the simple case is compared with results obtained in the published literature. Finally, effects of FGM index, electromechanical coupling, thickness ratio and thermo-mechanical surface boundary condition on the bending behaviour of beam are investigated. © 2009 Elsevier Ltd.

We study infinitesimal axisymmetric deformations of a functionally graded shell with piezoelectric layers perfectly bonded to its inner and outer surfaces, and the hybrid structure subjected to thermo-electro-mechanical loads. The material properties of the shell are assumed to be graded in the radial direction according to a power law but Poisson's ratio is assumed to be constant. For simply-supported and grounded edges kept at a constant temperature, the problem is analyzed analytically by assuming a Navier type solution for the governing equations and the state space method for solving the resulting ordinary differential equations. Numerical results are given to illuminate influences of the mechanical and the electrical boundary conditions, the exponent of the power law variation, and the radius to thickness ratio. © 2010 Elsevier Ltd.

Coordination Chemistry Reviews | Year: 2014

In this paper, there is an attempt to review the developments in the design and synthesis of pyridine containing [1+1] and [2+2] macrocyclic Schiff base ligands, formed by condensations of 2,6-diacylpyridine or 2,6-diformylpyridine and appropriate polyamines, which utilize the templating capability of different metal ions to direct the synthetic pathway. The reduction of the cyclic Schiff bases to their related amine derivatives is also considered since this leads to more flexible ligands capable of structural elaboration through donor groups. Attention is mainly paid to the synthetic and structural aspects of the resulting metal complexes, particularly to the role of the coordination preferences of the different metal ions in directing the synthesis totally or preferentially toward mono-, di- or poly-nuclear entities. The preparation of functionalized ligands, containing pendant arms, capable of promoting rapid complexation and decomplexation and their use in selective metal ion transportation and separation are also paid attention to. Furthermore, a summary of the new approach of these compounds such as mechanically interlocked molecules, catalytic properties and cofactors and artificial metalloenzymes is reviewed. © 2014 Elsevier B.V.

In this work, zinc oxide (ZnO) precursor was prepared by precipitation method from zinc nitrate and ammonium carbonate in aqueous solutions. ZnO nanoparticles were synthesized by annealing the precursor at different temperatures. The effect of the annealing temperature on the particle size and photo-luminescence (PL) properties of the synthesized ZnO nanoparticles were studied by XRD, SEM, BET, TG-DTA and PL measurements. The XRD results indicated that the synthesized ZnO nanoparticles had the pure wurtzite structure. It is found that with increasing the annealing temperature the crystalinity and particle size increases as well as the lattice parameters approaches to those of the XRD standard. The studies of the aggregation of the samples were also carried out by comparing SEM micrographs with specific surface measurements and XRD results. Finally, the room temperature PL spectra show UV emission peak in the range of 378.50-379.80 nm, which is close to the bulk ZnO. © 2012 Elsevier Ltd.

In order to enhance transient stability in a power system, a new intelligent controller is proposed to control a Static VAR compensator (SVC) located at center of the transmission line. This controller is an online trained wavelet neural network controller (OTWNNC) with adaptive learning rates derived by the Lyapunov stability. During the online control process, the identification of system is not necessary, because of learning ability of the proposed controller. One of the proposed controller features is robustness to different operating conditions and disturbances. The test power system is a two-area two-machine system power. The simulation results show that the oscillations are satisfactorily damped out by the OTWNNC. © 2012 Elsevier Ltd. All rights reserved.

In this study, a static synchronous series compensator (SSSC) is used to damp the subsynchronous oscillation in a power system compensated by the series capacitor. In order to achieve an effective damping, a supplementary subsynchronous damping controller (SSDC) is added to the SSSC. The only input signal for the SSDC is the rotor speed deviation to generate the modulation index for controlling the injected voltage of the voltage-sourced converter (VSC). Also, the chaotic optimisation algorithm is employed to tune the parameter of SSDC. The design objective is to suppress the subsynchronous resonance (SSR) caused by the series capacitor. By using the SSDC, the SSSC connected at the transmission line is able to damp the SSR. The first system of IEEE second benchmark model is used to evaluate the effective of SSDC on the torsional oscillations. The several simulations are used to demonstrate the ability of SSDC in damping the SSR. © 2012 The Institution of Engineering and Technology.
