Background: Spinach (Spinacia oleracea L.) has antioxidant, antiinflammatory, antiapoptotic and neuroprotective properties. The aim of this study was to investigate the effect of spinach hydroalcoholic extract on chronic restraint stress-induced spatial learning and memory deficit and anxiety in adult male rats. Methods: 60 adult male Wistar rats were allocated to six groups: Control group, Sp...

Introduction: Many clinical applications necessitate a limited scan time for dynamic MRI acquisition, e.g. due to breath hold or contrast passage. This often restricts attainable spatial and temporal resolution, limiting potential diagnostic or research applications. To reconstruct significantly undersampled time frames at clinically desired spatial/temporal resolution a number of approaches ha...

In the ultimate stage of the Adelson-Bergen motion energy model [Adelson, E. H., & Bergen, J. (1985). Spatiotemporal energy models for the perception of motion. Journal of the Optical Society of America, 2, 284-299], motion is derived from the difference between directionally opponent energies E(L) and E(R). However, Georgeson and Scott-Samuel [Georgeson, M. A., & Scott-Samuel, N. E. (1999). Mo...

Accurate protein function prediction is an important subject in bioinformatics, especially wheresequentially and structurally similar proteins have different functions. Malate dehydrogenaseand L-lactate dehydrogenase are two evolutionary related enzymes, which exist in a widevariety of organisms. These enzymes are sequentially and structurally similar and sharecommon active site residues, spati...

Least squares estimator of the stability parameter ̺ := |α|+ |β| for a spatial unilateral autoregressive process Xk,l = αXk−1,l +βXk,l−1 +εk,l is investigated and asymptotic normality with a scaling factor n5/4 is shown in the unstable case ̺ = 1. The result is in contrast to the unit root case of the AR(p) model Xk = α1Xk−1+ · · ·+αpXk−p+εk, where the limiting distribution of the least squares e...

spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location. in this paper we consider daily averages of troposphere ozone over tehran city. for eliminating the trend of data, a dynamic linear model is used, then some featu...
