A soft X-ray microscope using a highly intense laser-plasma soft X-ray source (laser-plasma soft X-ray microscope) has an ability to observe live biological cells with a spatial resolution higher than 100 nm in a very short time period. Using the laser plasma soft X-ray microscope inner structures of various live biological cells such as cellular organelles of Leydig cells of mouse testis and structure change caused by immunological functions of immunological cells have been observed. We used the laser-plasma soft X-ray microscope to observe structural deformation of nucleus due to apoptotic process which is one of important life functions. We have found the structural deformation of nuclei from ring structure to necklace and also found important structure inside of the nuclei for the first time.

We analyzed the yeast proteins expressed under the presence of Cs-137 by two dimensional electrophoresis to elucidate the mechanism of accumulation of radiocesium by microbes. We specified two proteins expressed specifically, two other proteins increased more, and two proteins decreased more under the condition. We did not observe any change of the protein expression under absence of Cs-137 and the presence of stable cesium isotope, Cs-133. These results indicate that different metabolic systems of yeast function under the above two conditions.
