## Abstract Nitric oxide (NO) production by astrocytes is a significant factor affecting brain physiology and pathology, but the mechanism by which it is regulated is not known. Previous studies using different specimens and stimuli might have described different aspects of a complex system. We inv

Nitric oxide (NO) is synthesized by nitric oxide synthases (NOS) and plays an important role in tumour growth. In this study, inducible NOS (iNOS) expression was evaluated by immunohistochemistry in 34 melanocytic naevi (13 common melanocytic naevi, six Spitz naevi, and 15 so-called 'dysplastic naev
## Abstract In scrapieβinfected cells, the conversion of the cellular prion protein to the pathogenic prion has been shown to occur in lipid rafts, which are suggested to function as signal transduction platforms. Neuronal cells may respond to bacterial lipopolysaccharide (LPS) treatment with a sus
