Objectives: Many clinicians are concerned about possible airway or respiratory complications following adenotonsillectomy for sleep related breathing disorder (SRBD), and routinely admit such patients for overnight monitoring. However, published guidelines suggest this is unnecessary in some cases. This study firstly aimed to establish current UK practice, and secondly to investigate whether children with mild/moderate SRBD experience respiratory problems during the first post-operative night.

Background: Studies of cellular signaling indicate that signal transduction pathways combine to form large networks of interactions. Viewing protein-protein and ligand-protein interactions as graphs (networks), where biomolecules are represented as nodes and their interactions are represented as links, is a promising approach for integrating experimental results from different sources to achieve a systematic understanding of the molecular mechanisms driving cell phenotype. The emergence of large-scale signaling networks provides an opportunity for topological statistical analysis while visualization of such networks represents a challenge.

Representation of intracellular signaling networks as directed graphs allows for the identification of regulatory motifs. Regulatory motifs are groups of nodes with the same connectivity structure, capable of processing information. The bifan motif, made of two source nodes directly crossregulating two target nodes, is an overrepresented motif in a mammalian cell signaling network and in transcriptional networks.
