(Taylor & Francis Ltd, 2020)
Background: Anosmia has been considered as the first diagnostic criteria of Parkinson disease (PD), we investigated the effect of the olfactory bulbectomy (OBX) on histopathological features of the substantia nigra in an ...
Estimating basilar artery upper rupture limit by dangerous alarming diameter of arteries (DADA) following bilateral common carotid artery ligation; a new theorem
(Taylor & Francis Ltd, 2020)
Background Although many theories have been established to explain the mechanism of aneurysm development following steno-occlusive or hypertensive disease, the effect of the geometrical shape of the inner elastic membrane ...

(Taylor & Francis Ltd, 2020)
Background: Few case reports describe an increase in the size of syringomyelia and the worsening of neurologic symptoms after surgery for foramen magnum decompression. We report three such cases. Material and method: ...
New histopathologic evidence for the parasympathetic innervation of the kidney and the mechanism of hypertension following subarachnoid hemorrhage
(Lippincott Williams & Wilkins, 2020)
Background: the Cushing response was first described in 1901. One of its components is elevated systemic blood pressure secondary to raised intracranial pressure. However, controversy still exists in its pathophysiologic ...
