Given a lattice L, a full dimensional polytope P is called a Delaunay polytope if the set of its vertices is S ∩ L with S being an empty sphere of the lattice. Extending our previous work [DD01] on the hypermetric cone HY P7, we classify the six-dimensional Delaunay polytopes according to their combinatorial type. The list of 6241 combinatorial types is obtained by a study of the set of faces o...

in 2011-2012 surveys for phytoplasma diseases, eggplant )solanum melongena l.( plants with phyllody symptoms were observed in eggplant fields of roodan (hormozgan province of iran). agent of roodan eggplant phyllody (rep) was transmitted from phyllody affected eggplant to eggplant and tomato by grafting and to periwinkle via dodder inoculation inducing phytoplasma-type symptoms. phytoplasmal in...

background: it is believed that bovine neutrophils contain several peptides and protein which exhibit antimicrobial activity against microorganisms such as fungi and bacteria. objectives: the purpose of this study was to isolate and purify a potential antibacterial protein from bovine neutrophil and test its anti bacterial activity. methods: neutrophils were isolated from bovine blood using dex...

Two different responses to the therapy were observed in a group of patients receiving the protease inhibitor indinavir. In one, suppression of virus replication occurred and has persisted for 90 weeks (bDNA, < 500 human immunodeficiency virus type 1 [HIV-1] RNA copies/ml). In the second group, a rebound in virus levels in plasma followed the initial sharp decline observed at the start of therap...

Wnt signaling is mediated by three classes of receptors, Frizzled, Ryk, and Ror. In Caenorhabditis elegans, Wnt signaling regulates the anterior/posterior polarity of the P7.p vulval lineage, and mutations in lin-17/Frizzled cause loss or reversal of P7.p lineage polarity. We found that pak-1/Pak (p21-activated kinase), along with putative activators of Pak, nck-1/Nck, and ced-10/Rac, regulates...

Breast cancer is the most common type of cancer in women worldwide. Elevated expression of the basic fibroblast growth factor (bFGF) has been found in patients suffering from breast cancer. We previously obtained a high-affinity bFGF-binding peptide (named P7) from a phage-display random heptapeptide library. In this study, we show that P7 peptides significantly inhibits the proliferation of the...

To study the morphogenesis and packaging of rice dwarf phytoreovirus (RDV), the interactions among multiple structural proteins were analysed using both the yeast two-hybrid system and far-Western blotting analysis. The following protein-protein interactions were observed. P3 (major core protein) bound to itself as well as to P7 (nucleic acid-binding protein) and P8 (major outer capsid protein)...

The existence of an on-line competitive algorithm for coloring bipartite graphs remains a tantalizing open problem. So far there are only partial positive results for bipartite graphs with certain small forbidden graphs as induced subgraphs, in particular for P7-free bipartite graphs. We propose a new on-line competitive coloring algorithm for P8-free bipartite graphs. Our proof technique impro...

The p7 protein is a small ion-channel-forming membrane polypeptide encoded by the hepatitis C virus which consists of two transmembrane alpha-helices, TM1 and TM2, and can be blocked by long-alkyl-chain iminosugar derivatives. The length of TM1 and TM2 was estimated by employing different secondary structure prediction algorithms and is proposed to span from Ala-10 to Leu-32 for TM1 and from Tr...
