    Jun Maruya
    Department of Neurosurgery, Akita Red Cross Hospital, Akita, Japan
    Neurol Med Chir (Tokyo) 48:114-7. 2008
    ..An extensive and informed discussion on the end-of-life treatment of clinically brain-dead patients is urgently required in Japan to establish treatment guidelines for such patients...

    Jun Maruya
    Department of Neurosurgery, Akita Red Cross Hospital, 222 1 Nawashirosawa, Saruta, Kamikitate, Akita 010 1495, Japan
    J Clin Neurosci 16:832-4. 2009
    ..We propose that primary intracranial germinoma should be included in the differential diagnosis of midbrain tumors, because early diagnosis and appropriate treatment for midbrain germinoma improves clinical outcome...

    J Stroke Cerebrovasc Dis 20:260-3. 2011
    ..The preoperative hypoperfusion might have been caused not only by the giant aneurysm, but also to some degree by the dolichoectatic MCA. After neck clipping, the increase in blood flow might have caused hyperperfusion...

    Acta Neurochir (Wien) 158:1247-50. 2016
    ..Our cases indicate that hypo-intensities on T2*GEI might change dynamically from the hyper-acute to the chronic period. The differences of susceptibility effects by hematoma age might be the cause of this dynamic change. ..
