the mesolimbic dopamine (da) system contains both d1-like and d2-like receptors, has been connected to control of locomotor behavior. an apparent role for d1 and d2 receptors throughout the mesolimbic system in the alteration of locomotor behavior has been demonstrated in pharmacological studies. the nucleus accumbens (nac) is comprised of a core and a shell subregion, which is a component of t...

because of continuous changing of anatomy, function and metabolism of the human brain, age- related change is a major risk factor in most prevalent neurodegenerative diseases, including parkinsons and huntingtons disease. therefore, knowing patterns of age-related atrophy of brain tissue can identify causes and possible role of diseases in decreasing brain function with age. the aim of this stu...

Gene expression in eukaryotes begins with transcription the nucleus, followed by synthesis of messenger RNA (mRNA), which is then exported to cytoplasm for its translation into proteins. Along and translation, mRNA export through nuclear pore complex (NPC) an essential regulatory step eukaryotic gene expression. Multiple factors regulate hence Interestingly, proteins from certain types viruses ...
