In the preoptic, infundibular and posterior recesses of the lamprey, Lampetra japonica cerebrospinal fluid (CSF)-contacting neurons are distributed much more abundantly than in higher vertebrates. They are classified into three different types on the basis of their granules size or electron density: type 1 containing round dense granules of large size (180--230 nm in diameter), type 2 containin...

The beneficial use of biventricular pacing is reported in a patient with hypertrophic cardiomyopathy and intraventricular conduction delay. This resulted in improvements in symptomatic status and exercise tolerance that may be related to cardiac resynchronisation. The improvement in symptoms by biventricular pacing in a patient with hypertrophic cardiomyopathy and intraventricular conduction de...

A balloon was introduced into the isolated rabbit left ventricle with intraventricular volume being controlled by a feedback amplifier. Pressure-volume and stiffness-pressure relations were determined as intraventricular volume was changed. These ventricular relations were explained according to the theory of wall muscle mechanics.

We describe our preliminary experience with the three-dimensional constructive interference in steady state (3D-CISS) sequence for the evaluation of intraventricular lesions. Cyst walls, extent and margins of tumors, and intratumoral cystic structures were clearly depicted on 3D-CISS images. The 3D-CISS sequence can offer additional information to conventional MR studies to define intraventricu...

Glioblastoma multiforme (GBM) is the most common primary brain tumor, but pure intraventricular location is extremely rare for GBM in neurosurgical practice. To our knowledge, there are only 19 reported cases to date. We present an additional case of intraventricular GBM with detailed clinical course, radiological and pathological findings.
