Pseudallescheria boydii is a rare opportunistic microorganism that usually infects immunosuppressed hosts. In this patient with cerebral infection by P boydii, imaging findings included enhancement of the ependyma of a lateral ventricle and of the caudate nucleus.

Ovariectomized ewes received unilateral infusions of 20 micrograms neuropeptide-Y (NPY) at a total of 13 intracerebral sites. Episodic secretion of luteinizing hormone (LH) was transiently suppressed on more than one occasion by daily infusions at a total of five intracerebral sites. Four of the effective sites were located within the third ventricle (two sites) and the rostral and ventral part...

The objective of the study was to evaluate the distribution of methotrexate (MTX) in cerebrospinal fluid (CSF) lateral ventricles and in cisterna magna after 3rd intraventricular CSF administration in a rabbit model. MTX or gadolinium chelate (Gd-DOTA) was administered in the 3rd ventricle with a local microdialysis to study the pharmacokinetics at the site of administration and with a simultan...

Objectives This study was done to evaluate the normal fetal cerebral lateral ventricle dimensions with transabdominal ultrasonography. The atrial width (AW), ventricle-to-choroid measurement (V-C), ventricle-to-hemisphere ratio (VHR), and combined anterior horn measurement (CAHM) were taken. Methods This was a cross-sectional study involving 400 normal singleton pregnant subjects whose gestatio...

BACKGROUND Little is known about the temporospatial shape characteristics of human lateral ventricles (LVs) during the first two years of life. This study aimed to delineate the morphological growth characteristics of LVs during early infancy using longitudinally acquired MR images in normal healthy infants. METHODS 24 healthy infants were MR imaged starting from 2 weeks old every 3 months du...

Six patients (ages ranging from 19 days to 58 years: three females and three males) with frontal horn coarctations are included into this study. Four of these six patients were found during our consecutive evaluation of 1022 cranial MR imaging examinations, obtained on a 0.5 Tesla unit. The condition was compared with ependymitis granularis. The sizes (largest diameter) of the frontal horn coar...

We reported five cases of lateral ventricle tumors all of which developed severe brain edema between 9 days and 8 years after surgery. Follow-up study with serial computed tomography before and after surgery were presented. Based on a review of the literature, a possible causal mechanism is suggested: 1) The cerebrospinal fluid diffuses into the white matter through the surgically damaged epend...

BACKGROUND Structural brain volume abnormalities are among the most extensively studied endophenotypes in schizophrenia. Bivariate genetic model fitting (adjusted to account for selection) was used to quantify the genetic relationship between schizophrenia and brain volumes and to estimate the heritability of these volumes. METHOD We demonstrated by simulation that the adjusted genetic model ...

Although many factors have been reported to change the R wave amplitude of the electrocardiogram (ECG), few observations have been made of the associated changes in T wave amplitude. We hypothesized that changes in R and T wave amplitude should parallel each other. To test this hypothesis, R and T wave amplitudes were measured in 15 normal subjects during increased and decreased left ventricula...

introduction: the septal area is an important telencephalic center that plays a prominent role in the learning, emotional sexual behaviour processes and autonomic functions. this area contains two main divisions; lateral (ls) and medial (ms), that receive numerus afferents from hippocampal formation. this study compares, quantitatively distributional pattern of the afferent neurons to these two...
