Technical innovations in brain tumour diagnostic and therapy have led to significant improvements of patient outcome and recurrence free interval. The use of technical devices such as surgical microscopes as well as neuronavigational systems have helped localising tumours as much as fluorescent agents, such as 5-aminolaevulinic acid, have helped visualizing pathologically altered tissue. Noneth...
Multiple brain tumors of diffuse large B cell lymphoma (DLBL) were observed in a 75-year-old man with Waldenström's macroglobulinemia (WM). Paravertebral and multiple subcutaneous nodules occurred in succession and he died 4 months after onset. We investigated B cell monoclonality by means of polymerase chain reaction (PCR) analysis and sequencing of the immunoglobulin heavy chain of paraffin-e...
We present a new 3D template atlas of the anatomical subdivisions of the macaque brain, which is based on and aligned to the magnetic resonance imaging (MRI) data set and histological sections of the Saleem and Logothetis atlas. We describe the creation and validation of the atlas that, when registered with macaque structural or functional MRI scans, provides a straightforward means to estimate...
Six ovine fetal brains were harvested 33 to 35 days postchallenge from 5 ewes, each of which was given 3000 Toxoplasma gondii oocysts on day 90 of pregnancy. Histopathologic examination of transverse sections taken at 13 levels in the fetal brains revealed the presence of toxoplasmosis-related lesions in all 6 brains. However, lesions were not randomly distributed (P = .007); they were most num...
The genesis of new cells, especially of neurons, in the adult human brain is currently of great scientific interest. In order to measure neurogenesis in animals new born cells are labelled with specific markers such as BrdU; in brain sections these can later be analyzed and counted through the microscope. So far, the image analysis has been performed by hand. In this work, we present an algorit...
AIMS To explore whether Chlamydia pneumoniae, Cytomegalovirus and Herpes Simplex Virus type 1 could be detected in large and small cerebral arteries, as well as in an area of brain parenchyma where white matter lesions (leukoaraiosis) can be found, in patients with clinically unmanifested cerebrovascular atherosclerosis. Methods and results( Arterial specimens from the basilar artery and middle...
BrainMaps.org is an interactive high-resolution digital brain atlas and virtual microscope that is based on over 20 million megapixels of scanned images of serial sections of both primate and non-primate brains and that is integrated with a high-speed database for querying and retrieving data about brain structure and function over the internet. Complete brain datasets for various species, incl...
