We discuss, on general grounds, how two subgraphs of a given Feynman graph can overlap with each other. For this, we use the notion connecting and returning lines that describe any subgraph is inserted within original graph. This, in turn, allows us to derive ``nonoverlap'' theorems for one-particle-irreducible 2, 3 4 external legs. As an application, provide simple justification skeleton expan...
This thesis is about phylogenetic trees mathematical graph structures which represent the pattern of evolution. More speci cally, it is concerned primarily with cladograms, the simplest type of phylogenetic tree, and the information they provide about the branching pattern of evolution. Although theoretical in orientation a real dataset is analysed in some detail and a user-friendly program pro...
The availability of large EST (Expressed Sequence Tag) databases has led to a revolution in the way new genes are cloned. Difficulties arise, however, due to high error rates and redundancy of raw EST data. For these reasons, one of the first tasks performed by a scientist investigating any EST of interest is to gather contiguous ESTs and assemble them into a larger virtual cDNA. The REX (Recur...
The scavenger receptor cysteine-rich (SRCR) proteins form an archaic group of metazoan proteins characterized by the presence of SRCR domains. These proteins are classified in group A and B based on the number of conserved cysteine residues in their SRCR domains, i.e. six for group A and eight for group B. The protein DMBT1 (deleted in malignant brain tumors 1), which is identical to salivary a...
To explore the mechanism of shear stress-induced downregulation of vascular cell adhesion molecule 1 (VCAM-1) expression in murine endothelial cells (ECs), we examined the effect of shear stress on VCAM-1 gene transcription and assessed the cis-acting elements involved in this phenomenon. VCAM-1 mRNA expression was downregulated at the transcriptional level as defined by nuclear run-on assay an...
