For direct observation of the surface structures of soft-tissue specimens, we examined rat tracheal tissue in a low-vacuum scanning electron microscope (SEM) equipped with a cooling stage. In specimens fixed with glutaraldehyde and osmium tetroxide, back-scattered electron images of the surface structure could not be clearly observed in the low-vacuum SEM(More)
A variable-pressure scanning electron microscopy (VP-SEM) with a cooling stage permits long hours of observation of water-containing specimens in their natural or close to natural state, without the conventional specimen preparations of fixation, dehydration, drying and metal coating. It reduces water vaporization and beam damage by keeping the specimens at(More)
T In our previous studies, TPI were found to be the molecules responsible for contact-killing of C. neoformans by S. aureus cells. Since TPI is a glycolytic protein that functions in the cytoplasm, evidence that TPI is present on the surface of S. aureus was required. In the present study, the presence of TPI on the cell surface of S. aureus was(More)
