Mechanisms by which the serotonergic system inhibits micturition in rats.

31 Aug 2009 AIMS: Serotonergic neurons and amino acid neurons are involved in the central nervous control of lower urinary tract function. We investigated the role of the serotonergic system in the central regulation of micturition, as well as the relationship ... Read more...

Measurements and mapping of 282,420 nerve fibers in the S1-5 nerve roots.

30 Aug 2009 OBJECT: The study aims to analyze nerve fiber types in the sacral nerve roots as a prerequisite for stimulation. METHODS: One-micrometer cross-sections of human ventral and dorsal S1-5 roots were stained with osmium and toluidine blue. The total ... Read more...

Precision of traditional approaches for lumbar plexus block: impact and management of interindividual anatomic variability.

30 Aug 2009 BACKGROUND: Traditional methods for approaching the lumbar plexus from the posterior rely on finding the intersection of lines that are drawn based on surface landmarks. These methods may be inaccurate in many cases. The aim of this study was to ... Read more...
