OBJECTIVE MicroRNA is a type of small non-coding RNAs, which usually has a stem-loop structure. As an important stage of microRNA, the pre-microRNA is transported from nuclear to cytoplasm by exportin5 and finally cleaved into mature microRNA. Structure-sequence features and minimum of free energy of secondary structure have been used for predicting(More)
Various abilities to synthesize and accumulate glycine betaine (GB) are crucial for angiosperms to develop salt and drought tolerances. In higher plants, GB is synthesized by a two-step oxidation of choline via an intermediate form of betaine aldehyde, and catalyzed by choline monooxygenase and betaine aldehyde dehydrogenase (BADH). In this study, numerous(More)
Aromatic rice is popular worldwide because of its characteristic fragrance. Genetic studies and physical fine mapping reveal that a candidate gene (fgr/OsBADH2) homologous to betaine aldehyde dehydrogenase is responsible for aroma metabolism in fragrant rice varieties, but the direct evidence demonstrating the functions of OsBADH2 is lacking. To elucidate(More)
Glycine betaine (GB), a quaternary ammonium solute, plays a crucial role in developing osmotic tolerance. Rice contains a choline monooxygenase (CMO) and two betaine aldehyde dehydrogenase homologues that are required for GB synthesis, but usually no GB is accumulated in rice (Oryza sativa). To elucidate the molecular processes that underlie the GB(More)
In several stress responsive gene loci of monocot cereal crops, we have previously identified an unusual posttranscriptional processing mediated by paired presence of short direct repeated (SDR) sequences at 5' and 3' splicing junctions that are distinct from conventional (U2/U12-type) splicing boundaries. By using the known SDR-containing sequences as(More)
Ligand-stabilized human telomeric G-quadruplex DNA is believed to be an anticancer agent, as it can impede the continuous elongation of telomeres by telomerase in cancer cells. In this study, five well-established human telomeric G-quadruplex DNA models were probed on their binding behaviors with thioflavin T (ThT) via both conventional molecular dynamics(More)
OBJECTIVE to explore the effect of catheter based renal synthetic denervation on renin-angiotensin-aldosterone system (RAAS) and blood pressure reduction in patients with resistant hypertension. and assess the validity and security of the treatment. METHODS Ten patients with resistant hypertension from June 2011 to December 2011 were retrospectively(More)
Glycine betaine (GB) is a compatible quaternary amine that enables plants to tolerate abiotic stresses, including salt, drought and cold. In plants, GB is synthesized through two-step of successive oxidations from choline, catalyzed by choline monooxygenase (CMO) and betaine aldehyde dehydrogenase (BADH), respectively. Rice is considered as a typical non-GB(More)
BACKGROUND Recent observational studies have shown that patients with chronic kidney disease (CKD) have higher risk of atrial fibrillation (AF) recurrence and, therefore, the value of catheter ablation therapy in patients with CKD has been doubted. The purpose of this meta-analysis was to systematically analyze the effect of CKD on recurrence of AF(More)
G-quadruplex is a noncanonical yet crucial secondary structure of nucleic acids, which has proven its importance in cell aging, anticancer therapies, gene expression, and genome stability. In this study, the stability and folding dynamics of human telomeric DNA G-quadruplexes were investigated via enhanced sampling techniques. First, temperature-replica(More)
