strategies of strengthening family foundation mohaddesi h , yusofi m* received: 22 april, 2010 accepted: 27 july, 2010 abstract background & aims: family is the first basis for psychosomatic growth and socialization of individuals in a community. family members who are uninformed or reckless about their rights and responsibilities will make a field for different psychosocial damages such as vio...

The deformation mechanisms of an alumina-forming austenitic stainless-steel Fe–20Cr–30Ni–2Nb–5Al (at. %) were investigated at 750 °C using both creep tests and strain rate jump tests. It was found that nano-sized L12-structured precipitates the dominant precipitate in matrix provided majority strengthening. This behavior could be modeled well a threshold stress term power law equation. Addition...

A long-standing hypothesis termed "Hebbian plasticity" suggests that memories are formed through strengthening of synaptic connections between neurons with correlated activity. In contrast, other theories propose that coactivation of Hebbian and neuromodulatory processes produce the synaptic strengthening that underlies memory formation. Using optogenetics we directly tested whether Hebbian pla...

This article explores the adequacy of international governance mechanisms to address environmental issues. It examines the impact of increased global economic integration on national and regional environmental standards, the role of market mechanisms in facilitating the dissemination of environmental standards from greener nations to less green ones and the impact of international agreements on...

Experience-dependent plasticity is the adaptability of brain circuits as a result of changes in neural activity, a phenomenon that has been proposed as the neural basis for important brain function in health and disease. The underlying mechanisms of experience-dependent plasticity can take different forms, depending on the organisms and brain areas under investigation. A better understanding of...

In response to decreased activity, neurons make global compensatory increases in excitatory synaptic strength. However, how neuronal maturity affects this process is unclear. We silenced cultured hippocampal neurons with TTX at 7 days in vitro, during rapid synaptogenesis, and at 14 days, when major synaptogenesis is complete. For each age, we have explored the effects of short (1 day) and long...

background: the purpose of this study was to investigate the effects of two types of rehabilitation techniques, including aerobic and strengthening exercises on patients with knee rheumatoid arthritis (ra). methods: 48 male patients with knee ra were randomly assigned into 3 groups, including aerobic exercises, strengthening exercise, and control. the two first groups completed their treatment ...

The mechanisms by which neuroligin adhesion molecules modulate synaptic plasticity remain unclear. In this issue, Liu et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201509023) demonstrate that neuroligin 1 promotes actin assembly associated with synaptic strengthening independent of adhesion, suggesting additional ways for neuroligins to contribute to neuronal development and disease...
