The term ‘deteriorated texture’ gives all experts as well as ordinary people almost the sameimpression. Despite common points in images, the differences put Iran cities in different categories based on deteriorated textures. This classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. F...

conclusions the pattern of longitudinally increased liver stiffness measurements efficiently supported clinical decisions for individualized management strategies. repeated transient elastography in real-life clinical practice appears to have a practical role in monitoring liver transplanted patients. background liver transplanted patients need close surveillance for early signs of graft diseas...

In this paper, an analytical formula to calculate the radial stiffness of groove elastic support is presented. The influence of structure parameters on radial stiffness and homogeneity of radial stiffness is investigated as well. The accuracy and calculating speed of the analysis formula are compared to that of finite element method (FEM). Findings are as following: The calculating speed of ana...

Abstract Introduction Regular aerobic exercise reverses aging-induced deterioration of arterial stiffness via an increased nitric oxide (NO) production. Concurrently, asymmetric dimethylarginine (ADMA), endogenous inhibitor NO synthase, was decreased by training. A recent study showed that the NOx/ADMA ratio reflects endothelial function and may be index states cardiovascular disease. However, ...

Classic theories of ageing consider extrinsic mortality (EM) a major factor in shaping longevity and ageing, yet most studies of functional ageing focus on species with low EM. This bias may cause overestimation of the influence of senescent declines in performance over condition-dependent mortality on demographic processes across taxa. To simultaneously investigate the roles of functional sene...

We suggest that working memory (WM) performance can be conceptualized as the interplay of low-level feature binding processes and top-down control, relating to posterior and frontal brain regions and their interaction in a distributed neural network. We propose that due to age-differential trajectories of posterior and frontal brain regions top-down control processes are not fully mature until ...

The past several decades have witnessed unidimensional decline models of aging give way to life-span developmental models that consider how specific processes and strategies facilitate adaptive aging. In part, this shift was provoked by the stark contrast between findings that clearly demonstrate decreased biological, physiological, and cognitive capacity and those suggesting that people are ge...

Abstract This paper documents the sectoral growth paths of measured total factor productivity (TFP) in southern Europe during the boom that proceeded the great contraction (1996 to 2007). Using both aggregate and firm-level panel data, I show that TFP in sectors that displayed fast expansion, such as construction, dropped significantly, while in non-expanding sectors, such as manufacturing, it ...

UNLABELLED BACKGROUND/STUDY CONTEXT: Typical measures for assessing the useful field (UFOV) of view involve many components of attention. The objective of the current experiment was to examine differences in visual search efficiency for older individuals with and without UFOV impairment. METHODS The authors used a computerized screening instrument to assess the useful field of view and to cha...

The influence of a structural modification on thermodynamic aspects of solubility and hydration processes of 1,2,4-thiadiazole drug-like compounds was investigated. A substitution in the phenyl ring of the 1,2,4-thiadiazole molecule leads to a significant decrease of the solubility of these compounds. In order to rationalize the relationship between the structures of 1,2,4-thiadiazoles and thei...
