22-Oxacalcitriol the analog with low calcemic effect and the original hormone 1,25(OH)2 vitamin D3 were localized by autoradiography in mouse stomach at different time intervals after intravenous injection. Both compunds showed a distinct nuclear concentration and retention in neck mucous cells of gastric and pyloric glands, and in dispersed endocrine cells(More)
Because of the therapeutic potential of oxacalcitriol (OCT, 22-oxa-dihydroxyvitamin D3), in vivo studies were conducted in adult and neonatal rats to identify the nuclear receptor sites of action in different tissues of the skin. Results were compared with those for 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) and oestradiol from previous studies. Autoradiograms(More)
A new remote laboratory system for learning hardware designs and experiment of digital circuits has been developed. Wide use of the Internet motivated us to develop seamless remote and actual hardware laboratories for hardware design laboratory course. Unlike existing virtual laboratories, the proposed remote laboratory utilizes actual hardware and actual(More)
Target cells for 3H-labeled 1α, 25(OH)2 vitamin D3 [1,25(OH)2D3, vitamin D] and its analog 3H-labeled 22-oxa-1α, 25(OH)2 vitamin D3 (OCT) have been identified during endochondral and intramembranous ossification in developing, undecalcified, unembedded bone, using thaw-mount autoradiography. Two-day-old neonatal rats were injected with [3H]1,25(OH)2D3 or(More)
The distance learning is widely spreading its use in many areas thanks to the Internet advancement. One of the emerging areas is the remote laboratory. The proposed remote laboratory system is to realize an internet based remote digital logic circuit experiment, which enables efficient sharing of test equipments both in space and time division fashions as(More)
This work describes the authors' approach at their university in the last three years for computer science second grade undergraduate students to experience parallel and distributed computing. The goal is to give a solid understanding of parallel and distributed processing technologies and to build up basic skills in the field, such as parallel algorithms,(More)

early gastr ic cancer. Some biochemical changes, especially of the high molecular substances, peculiar to the gastric juice of gastric cancer have already been reported in our previous papers. In this study, the continuous pH t i trat ion method of gastric juice, which was originally designated by us, was investigated in reference to the gastric mucosal(More)
