Do inclusion of chloroplast genes that have undergone expansion misleads phylogenetic reconstruction in the Chlorophyta?
The Rps sequences can explain earlier findings linking Leptosira with the Chlorophyceae and should be excluded from phylogenetic analyses attempting to resolve deep nodes because their expansion violates the assumptions of substitution models. We reaffirm that Leptosira is a trebouxiophycean and that fragmentation of rpoB has occurred at least twice in chlorophyte evolution.
Botulinum toxin A injection into the trigone does not induce de novo vesicoureteral reflux in patients with nonneurogenic overactive bladder. The therapeutic value of this approach remains to be confirmed and compared to other injection designs.
