The cohort has increased to 1825 children, with 4134 patient-years of follow-up, and we determined the incidence of AE in this expanded cohort and described the severity, management, and loca...
In this issue of Genes & Development, Wierzbicki and colleagues (pp. 1825-1836) examine the current model of RNA-directed DNA methylation (RdDM) by determining genome-wide distributions of RNA polymerase V (Pol V) occupancy, siRNAs, and DNA methylation. Their data support the key role of base-pairing between Pol V transcripts and siRNAs in targeting de novo DNA methylation. Importantly, the stu...
Bartholomew's Hospital, where he had trained towards the end of the long career of John Abernethy, who attracted large numbers of students to his lectures. He had begun his medical career in the 1820s (L.S.A. 1824, M.R.C.S. 1825) and subsequently gained an F.R.C.S. by examination in 1847, and an M.D. from the University of St Andrews in 1856, during the course of his medical practice in Yeovil.
The status of two doubtful fish species is reviewed. Percis punctata Cuvier, 1829 is confirmed to be a valid species of Parapercis Bleeker, 1863 and a senior synonym of Parapercis guezei Fourmanoir, 1966. A redescription of Parapercis punctata is provided, based on four specimens collected from the western Indian Ocean. Examination of the holotype of Neosillago marmorata Castelnau, 1875 reveale...
