We present a case of large placental hemangioma comprising more than half of the organ and not causing feto-maternal complications. It appeared after 29 weeks of gestation. At 29 weeks an ...ultrasonography disclosed a normal placenta. At 35 weeks of gestation it measured 60 x 57 mm and appeared as a well delineated hypoechoic image. Delivery took place at 38 weeks by cesarean section and the child was normal.
Atrial fibrillation (AF) is a heritable disease that affects more than thirty million individuals worldwide. Extensive efforts have been devoted to the study of genetic determinants of AF. The ...objective of our study is to examine the effect of gene-gene interaction on AF susceptibility. We performed a large-scale association analysis of gene-gene interactions with AF in 8,173 AF cases, and 65,237 AF-free referents collected from 15 studies for discovery. We examined putative interactions between genome-wide SNPs and 17 known AF-related SNPs. The top interactions were then tested for association in an independent cohort for replication, which included more than 2,363 AF cases and 114,746 AF-free referents. One interaction, between rs7164883 at the HCN4 locus and rs4980345 at the SLC28A1 locus, was found to be significantly associated with AF in the discovery cohorts (interaction OR = 1.44, 95% CI: 1.27-1.65, P = 4.3 x 10(-8)). Eight additional gene-gene interactions were also marginally significant (P < 5 x 10(-7)). However, none of the top interactions were replicated. In summary, we did not find significant interactions that were associated with AF susceptibility. Future increases in sample size and denser genotyping might facilitate the identification of gene-gene interactions associated with AF.

The relative importance of a node in wireless mesh networks (WMNs) is typically related to its topological position and data forwarding capacity. In dynamic scenarios, however, these particular ...characteristics may change over time. In the analysis of complex networks, the concept of network centrality reflects the relative importance of a node within a network. We first show the current centrality metrics are unable to dynamically classify nodes in the scenarios we target. We then propose the Dynamic Labeling of Nodes (DyLaN), a new metric that aims at identifying and monitoring the most important nodes in time-varying WMN scenarios. We evaluate DyLaN using real-world traces showing that it can improve the quality of managing such dynamic WMNs.
The quantum Hall liquid-Hall insulator transition has been studied using a gate-controlled periodical lattice of antidots. This system allows us to probe deep into the phase-space of the transition ...at both low and high magnetic fields. It is shown, that the transition occurs when the longitudinal and Hall conductivities are equal to each other. Thus, contrary to the scaling delocalisation model, renormalisation occurs only when

τ=1. The Hall resistivity at the transition point is close to its classical value, as predicted by the Chern-Simons-Landau-Ginzburg theory of the quantum Hall effect.
The leaf and inflorescence oils of Ocimum micranthum Willd. were investigated by GC (retention time data), GC/MS and 13C-NMR spectroscopy. The main constituents in the leaves were eugenol (44.8%) and ...beta-caryophyllene (14.7%), whereas in the inflorescence elemicin (32.9%) and eugenol (14.0%) were the major compounds
