Leukocyte lipid bodies are dynamic, functionally active organelles with central roles in inflammation. Here, we report that leukocyte lipid bodies are facilely detected by a versatile, potent technique, termed wet scanning electron microscopy (SEM), which combines the rapid preparation of light microscopy with the resolution of SEM. Using as leukocyte models resting and agonist-stimulated human...

The 5'-to-3' mRNA degradation machinery localizes to cytoplasmic processing bodies (P-bodies), which are non-membranous structures found in all eukaryotes. Although P-body function has been intensively studied in yeast, less is known about their role in mammalian cells, such as whether P-body enzymes are actively engaged in mRNA degradation or whether P-bodies serve as mRNA storage depots, part...

The interplay between the neural mechanisms of visual awareness and those involved in emotion processing and the mapping of related somatic changes remains unclear. To address this issue we studied one patient with visual extinction following right parietal damage, in a combined behavioral, psychophysiological and neuroimaging experiment. Patient M.P. was presented with neutral and fearful bodi...

Glucose is the preferred carbon source for most eukaryotes and so it is important that cells can sense and react rapidly to fluctuations in glucose levels. It is becoming increasingly clear that the regulation of gene expression at the post-transcriptional level is important in the adaptation to changes in glucose levels, possibly as this could engender more rapid alterations in the concentrati...

Cajal bodies are nuclear sites of small ribonucleoprotein (RNP) remodeling and maturation. A recent study describes the discovery of the Drosophila Cajal body, revealing some interesting insights into the subnuclear organization of RNA processing machineries among different species.

Individuals with body dysmorphic disorder (BDD) and clinically concerning body-image concern (BIC) appear to possess abnormalities in the way they perceive visual information in the form of a bias towards local visual processing. As inversion interrupts normal global processing, forcing individuals to process locally, an upright-inverted stimulus discrimination task was used to investigate this...
