Development of X-ray phase CT with a hybrid configuration of Lau and Talbot-Lau interferometers.

X-ray phase computed tomography (CT) is used to observe the inside of light materials. In this paper, we report a new study to develop and test a laboratory assembled X-ray phase CT system that comprises an X-ray Lau interferometer, a rotating Mo anode X-ray tube, and a detector with high spatial resolution. The system has a high spatial resolution lower than 10 μm, which is evaluated by differentiating neighbouring carbon fibres in a polymer composite material.

Decreased sodium influx and abnormal red cell membrane lipids in a patient with familial plasma lecithin: cholesterol acyltransferase deficiency.

Red cell membrane metabolism in familial lecithin:cholesterol acyltransferase (LCAT) deficiency was investigated. The family presented here is the third case discovered in Japan. An increase of free cholesterol was observed in the red cell membranes, concomitant with increased phosphatidyl choline.
