Methylmercury selectively damages the central nervous system (CNS). The tumor necrosis factor (TNF) superfamily includes representative cytokines that participate in the inflammatory response as well as cell survival, and apoptosis. In this study, we found that administration of methylmercury selectively induced TNF-α expression in the brain of mice. Although the accumulated mercury concentration in the liver and kidneys was greater than in the brain, TNF-α expression was induced to a greater extent in brain...

A novel member of the Acidobacteria was isolated from a microbial mat growing on a geothermally-heated dead tree trunk in Hawai'i Volcanoes National Park (Hawai`i, USA). The rod-shaped, Gram-negative capsulated cells of strain PMMR2T were non-motile, and catalase and oxidase negative. Growth occurred aerobically from 15 oC - 55 oC (optimum 40 oC), and at pH values from 4.5 - 7.0 (optimum 6.5). A limited range of sugars and organic acids supported growth. However, results of a genomic analysis suggested that various polysaccharides might be hydrolyzed as carbon sources, and evidence for pectin degradation was observed in liquid cultures...

OBJECTIVE The aims of this study were to determine if the morphological and functional changes induced by neural stem cell (NSC) grafts after transplantation into the rodent spinal cord can be detected using MR diffusion tensor imaging (DTI) and, furthermore, if the DTI-derived mean diffusivity (MD) metric could be a biomarker for cell transplantation in spinal cord injury (SCI). METHODS A spinal contusion was produced at the T-8 vertebral level in 40 Sprague Dawley rats that were separated into 4 groups, including a sham group (injury without NSC injection), NSC control group (injury with saline injection), co-injection control group (injury with Prograf), and the experimental group (injury with NSC and Prograf injection)...
