INTRODUCTION There are variations in the anatomy of the vertebrobasilar system amongst which the Anterior Inferior Cerebellar Artery-Posterior Inferior Cerebellar Artery (AICA-PICA) variant is thought to have a prevalence of 20-24% (based on retrospective studies). Despite this, aneurysms of the AICA-PICA variant are rare. We present a case of an AICA-PICA aneurysm and discuss its presentation ...

BACKGROUND With the technical advance of magnetic resonance imaging (MRI), we have been able to observe not only the small cranial nerves arising from the brain stem but also the branches of vertebrobasilar artery in the cerebellopontine angle (CPA) cistern. PURPOSE The purpose was to demonstrate the courses and configurations of the anterior inferior cerebellar artery (AICA) or posterior inf...

cisplatin is an effective chemotherapeutics against a wide range of cancers. however, it causes significant nausea and vomiting which limit its usefulness. in the present study, the effects of methanolic root extract of pluchea lanceolata (dc.) c. b. clarke , asteraceae ( mpl ) was investigated against cisplatin-induced nausea using a rat pica model. in rat pica model, rats react to cisplatin (...

Although response blocking can decrease problem behavior, one potential adverse side effect is the induction of aggression. In the current study, we report on a young adult who engaged in high rates of pica maintained by automatic reinforcement. Blocking pica, however, led to aggression. When redirection to an alternative preferred food item was added to an intervention consisting of response b...

A 57-year-old man presented with subarachnoid hemorrhage caused by a dissecting aneurysm of the vertebral artery close to the origin of the posterior inferior cerebellar artery (PICA). The aneurysm was treated successfully with two fenestrated clips preserving the efferent artery with anterograde blood flow without PICA anastomosis. The postoperative course was uneventful. Postoperative angiogr...

The double origin of the posterior inferior cerebellar artery (PICA) is a variant anastomosis of a residual lateral spinal artery and native intracranial PICA that has been associated with intracranial aneurysm formation. Because of this anastomosis, both origins of the PICA serve as aneurysmal-feeding vessels. We describe a novel technique of coiling with intracranial stent assistance to treat...

Holistic Principal Component Analysis (PCA) and holistic Independent Component Analysis (ICA) methods require long training times and large storage spaces for the recognition of facial images. These drawbacks can be avoided by using partitioning-based methods, namely partitioned PCA (pPCA) and partitioned ICA (pICA), which yield similar performance for pPCA and improved performance for pICA met...

BACKGROUND Pica, the craving and subsequent consumption of non-food substances such as earth, charcoal, and raw starch, has been an enigma for more than 2000 years. Currently, there are little available data for testing major hypotheses about pica because of methodological limitations and lack of attention to the problem. METHODOLOGY In this paper we critically review procedures and guideline...
