Measurement of nationwide indoor Rn concentration in Japan
Abstract Indoor Rn ( 222 Rn) concentrations in Japan were measured to estimate the effective dose to the general public due to Rn and its progeny. Twenty houses were selected in each prefectureExpand

Extensive Field Survey of Natural Radiation in Japan
The exposure rate due to natural radiation composed of terrestrial radiation, cosmic ray as well as a slight contribution from nuclear tests was estimated at 1,115 sites by an ionization chamber andExpand

Site-specific transition of cytosine to uracil via reversible DNA photoligation.
We report that deamination coupled with 5-carboxyvinyldeoxyuridine-mediated photobranching causes the heat-induced transition of cytosine to uracil with high efficiency without any side reaction.

Ultrafast reversible photo-cross-linking reaction: toward in situ DNA manipulation.
We describe a novel ultrafast reversible DNA interstrand photo-cross-linking reaction via 3-cyanovinylcarbazole nucleoside ( (CNV)K). Oligodeoxynucleotide (ODN) containing (CNV)K can beExpand

Characterization of human telomere RNA G-quadruplex structures in vitro and in living cells using 19F NMR spectroscopy
Abstract Human telomeric RNA has been identified as a key component of the telomere machinery. Recently, the growing evidence suggests that the telomeric RNA forms G-quadruplex structures to play anExpand

Photoinduced deoxyribose C2' oxidation in DNA. Alkali-dependent cleavage of erythrose-containing sites via a retroaldol reaction
Photoreactions of various 5-iodouracil-( I U)-containing oligonucleotides have been investigated. It was found that d(GCA I UGC) 2 undergoes a competitive Cl' and C2' oxidation at the 5' side of theExpand

Evidence for intrastrand C2′ hydrogen abstraction in photoirradiation of 5-halouracil-containing oligonucleotides by using stereospecifically C2′-deuterated deoxyadenosine
In order to investigate the nature of deoxyribose C1′ and C2′ H abstraction by uracilyl-5-yl radical in DNA, we have examined the photoreaction of hexanucleotides d(GCABrUGC)2 in which one of the C2′Expand

Site-specific photochemical RNA editing.
Photo-induced artificial RNA editing was demonstrated using photo-reactive oligonucleotides containing 3-cyanovinylcarbazole nucleoside. This non-enzymatic and sequence-specific methodology will makeExpand
