Nepetalactones are iridoid monoterpenes with a broad range of biological activities produced by plants in the Nepeta genus. However, none of the genes for nepetalactone biosynthesis have been discovered. Here we report the transcriptomes of two Nepeta species, each with distinctive profiles of nepetalactone stereoisomers. As a starting point for investigation of nepetalactone biosynthesis in Ne...

introduction: it has been reported that oral morphine dependency facilitated formation of spatial learning and memory. in the present study the role of nmda receptors located in hippocampal ca1 area of morphine dependent rats was studied. methods: male rats were divided into 4 groups. two cannulae were stereotaxically implanted bilaterally into the hippocampal ca1 area. after 5 days recovery, a...

introduction: children with attention deficit hyperactivity disorder have problem in sustain attention that is necessary for learning. the purpose of present study is comparing explicit and implicit memory in children with attention deficit disorder and typically developing children. material and methods: in present cross sectional study, fifteen children with attention deficit disorder compare...

abstract: introduction: nitric oxide (no) is a retrograde messenger in hippocampal synaptic plasticity which involves in learning and memory processes. previous studies revealed that hippocampal pyramidal cells contain no synthase (nos) enzyme which produce no and could be a promising target to evaluate the role of no in brain cognitive functions. so in this study, using nos inhibitor (l-name),...
