Detailed three-dimensional morphological information of the cell without distortion due to thin sectioning can be obtained from thick sections using a confocal laser scanning microscope. Here that microscope was used to evaluate human gingival Langerhans cells stained with anti-CD1a antibody. Optical sectioning and reconstruction by laser scanning(More)
The cerebral lesions in tuberous sclerosis are of three kinds: subependymal nodules, cortical tubers, and cluster of heterotopic cells in the white matter. Understanding of these hamartomas is still incomplete even with modern imaging modalities. Magnetic resonance (MR) images of ten patients with tuberous sclerosis were reviewed and compared to computed(More)
Fertilization is known to initiate a transient increase of intracellular calcium concentration and an accompanying change of membrane potential in sea urchin eggs. If the fertilization membrane and hyaline layer are removed, sperm can again enter fertilized eggs (refertilization). We have found that Ca2+ and voltage transients were repeatedly induced in(More)
An epitaxial InP/InGaAs/InP structure was grown on 2-in-diameter InP substrates by the chloride vapor-phase epitaxy (VPE) method. The undoped carrier concentration of both the InP and InGaAs layers was less than 1*10/sup 15/ cm/sup -3/. Hall mobility at 77 K was 85000 cm/sup 2//V-s. The variation of epi-layer thickness, carrier concentration and lattice(More)
Magnetic resonance (MR) images of 29 consecutive patients with intraspinal neoplasms (9 intramedullary tumors, 20 extramedullary tumors) were reviewed to evaluated the utility of MR imaging in distinguishing the intraspinal compartmental localisation and signal characteristics of each lesion. Compartment and histology of all neoplasms were surgically(More)
This paper studied the effect of lens aberration on coupling efficiency and loss penalty due to misalignment for a laser diode to single-mode fiber couplers. The theoretical results were in very good agreement with experimental values and the validity of the present analysis was confirmed. The paper made clear that coupling loss is dominated by aberration(More)
(101) THE EFFECT OF CALCIUM ON HUMAN GASTRIC SECRETION K. Segawa, S. Nakazawa, N. Koide, K. Imai, N. Matsuo, Y. Yamamoto and M. Shiobara 2nd Dept. of Int. Med., Nagoya Univ., Sch. of Med. The effect of calcium on gastric secretion was studied in 10 duodenal ulcer patients, 6 gastric ulcer patients and 1 case of Z-E syndrome. After the overnight fasting, the(More)
Some ascidians (sea squirts) accumulate the transitional metal vanadium in their blood cells at concentrations of up to 350 mM, about 10(7) times its concentration found in seawater. There are approximately 10 different types of blood cell in ascidians. The identity of the true vanadium-containing blood cell (vanadocyte) is controversial and little is known(More)
