In eubacteria, PriA helicase detects the stalled DNA replication forks. This critical role of PriA is ascribed to its ability to bind to the 3' end of a nascent leading DNA strand in the stalled replication forks. The crystal structures in complexes with oligonucleotides and the combination of fluorescence correlation spectroscopy and mutagenesis reveal(More)
BACKGROUND Immediate access to patients' complete health records via electronic databases could improve healthcare and facilitate health research. However, the possible benefits of a national electronic health records (EHR) system must be balanced against public concerns about data security and personal privacy. Successful development of EHR requires better(More)
BACKGROUND In the mammalian genome, a substantial number of gene pairs (approximately 10%) are arranged head-to-head on opposite strands within 1,000 base pairs, and separated by a bidirectional promoter(s) that generally drives the co-expression of both genes and results in functional coupling. The significance of unique genomic configuration remains(More)
Specific targeting of tissues and/or cells is essential for any type of drug delivery system because this determines the efficacy and side effects of the drug. Poly lactic-co-glycolic acids (PLGA) have long been used as biomaterials for drug delivery due to their excellent biocompatibility and biodegradability. Direct visualization of PLGA particles is(More)
OBJECTIVES Epileptic spasms (ES) in West syndrome (WS) are classified as being of the generalized seizure type. However, evidence of a focal neocortical origin has been proposed based mainly on surgical WS series. We report herein two infants with WS, whose ES subsequently evolved into focal ES of the right lower extremity. METHODS Medical records,(More)
We evaluated in vivo functional selectivity profiles for muscarinic M(2) and M(3) subtypes of four muscarinic antagonists: Compound A (a novel muscarinic receptor antagonist with M(2)-sparing antagonistic activity), darifenacin, (a muscarinic M(3) receptor antagonist); methoctramine (a muscarinic M(2) receptor antagonist) and tolterodine (a nonselective(More)
