The photosynthetic membranes of cyanobacteria and chloroplasts of higher plants have remarkably similar lipid compositions. In particular, thylakoid membranes of both cyanobacteria and chloroplasts are composed of galactolipids, of which monogalactosyldiacylglycerol (MGDG) is the most abundant, although MGDG biosynthetic pathways are different in these(More)
Monogalactosyldiacylglycerol (MGDG), which is conserved in almost all photosynthetic organisms, is the most abundant natural polar lipid on Earth. In plants, MGDG is highly accumulated in the chloroplast membranes and is an important bulk constituent of thylakoid membranes. However, precise functions of MGDG in photosynthesis have not been well understood.(More)
Radiocarbon ((14)C) provides a way to date material that contains carbon with an age up to ~50,000 years and is also an important tracer of the global carbon cycle. However, the lack of a comprehensive record reflecting atmospheric (14)C prior to 12.5 thousand years before the present (kyr B.P.) has limited the application of radiocarbon dating of samples(More)
AIMS To evaluate the effect of topical diquafosol in patients with meibomian gland dysfunction (MGD) using tear film parameters and quantitatively analyse the meibomian gland morphology. SUBJECTS AND METHODS The subjects were 19 eyes of 10 patients diagnosed with obstructive MGD. All subjects were given 3% diquafosol ophthalmic solution with instructions(More)
AIMS To evaluate objectively the meibomian gland area using newly developed software for non-invasive meibography. METHODS Eighty eyelids of 42 patients without meibomian gland loss (meiboscore=0), 105 eyelids of 57 patients with loss of less than one-third total meibomian gland area (meiboscore=1), 13 eyelids of 11 patients with between one-third and(More)
In Mizumaki-cho, Fukuoka, a "School of muscle-building for the elderly" was held by the self-help group "MIZUMAKI Iki-iki senior club" once a week from Sep. 2002 to Mar. 2004. This school program included stretching, aerobics and resistance exercises. In this study, we clarified the effect of exercise for the 38 elderly females in this school. Their average(More)
The successful analysis of LiDAR data for archaeological research requires an evaluation of effects of different vegetation types and the use of adequate visualization techniques for the identification of archaeological features. The Ceibal-Petexbatun Archaeological Project conducted a LiDAR survey of an area of 20 × 20 km around the Maya site of Ceibal,(More)
Chemical modification of nucleic acids is being studied extensively as an approach for the development of nucleic acid-based therapies. We found that a nucleotide carrying 7,8-dihydropyrido[2,3-d]pyrimidin-2-one (bicyclic-C or X), which is a cytosine derivative with a propene attached at the N4 and C5 atoms, increases the stability of DNA duplexes. To(More)
The synthesis of small glycoclusters with high affinity toward lectins is one of the important subjects in glycotechnology. Although cyclic α-(1→6)-d-octaglucoside (CI8) is an attractive scaffold on which to put glycosyl pendants, the compound has only secondary hydroxyl groups, which are relatively unreactive for substitution reactions. The oxidation of(More)
