Ekram Mohammadi, Sedigheh Ghasemi,

A person, who is talented, performs in a certain capacity above the norm. Talent is different from intelligence which is a response to a circumstance using knowledge and skill. The attributes of talent are exceptional memory, rapid processing speed, and high motivation, an affinity for learning, creativity and optimal cognition. There is some proof suggests that certain aspects of talent are re...

Introduction: Oxidative stress plays a crucial role in the impairment of synaptic plasticity following cerebral ischemia which ultimately results in memory dysfunction. Hence, application of antioxidant agents could be beneficial in the management of memory deficit after brain ischemia. Minocycline is a tetracycline antibiotic with antioxidant effect. The main objective of this work was to asse...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

methods of modulating brain neural plasticity, improving memory and learning, improving recovery from traumatic brain injury, preventing epilepsy, treating memory disorders, and treating persistent impairment of consciousness in humans and animals by nerve stimulation are provided. widespread loss of cerebral connectivity is assumed to underlie the failure of brain mechanisms that support commu...

Adaptation to heterogeneous environments can occur via phenotypic plasticity, but how often this occurs is unknown. Reciprocal transplant studies provide a rich dataset to address this issue in plant populations because they allow for a determination of the prevalence of plastic versus canalized responses. From 31 reciprocal transplant studies, we quantified the frequency of five possible evolu...

Ecology and evolution have long been recognized as reciprocally influencing each other, with recent research emphasizing how such interactions can occur even on very short (contemporary) time scales. Given that these interactions are mediated by organismal phenotypes, they can be variously shaped by genetic variation, phenotypic plasticity, or both. I here address 8 key questions relevant to th...

low stacking fault energy face centered cubic (fcc) materials contain characteristic defect structures. stackingfault tetrahedral are one of those rare structures that occur under special experimental conditions. for the first time,stacking fault tetrahedral were observed in fe-30mn-3al-3si twinning induced plasticity (twip) steel. theirpresence resulted from a quenching heat treatment.

Plasticity is a specific endowment of the nervous system to develop, to react or to adjust to the internal and external 'environmental changes, both in the physiological and pathological conditions. Cumulative evidence has revealed the dynamism of the nervous system, based on the balance between the rigidity and plasticity. Different aspects of neuroplasticity can employ common general cellular...

Horizontal connections in superficial cortical layers integrate information across sensory maps by connecting related functional columns. It has been hypothesized that these connections mediate cortical reorganization via synaptic plasticity. However, it is not known if the horizontal connections from discontinuous cortical regions can undergo plasticity in the adult. Here we located the border...
