Organization of replicating prokaryotic genomes requires architectural elements that, similarly to eukaryotic systems, induce topological changes such as DNA supercoiling. Bacteriophage 29 protein p6 has been described as a histone-like protein that compacts the viral genome by forming a nucleoprotein complex and plays a key role in the initiation of protein-primed DNA replication. In this work...

The P6 outer membrane protein is a highly conserved molecule which is present on the surface of all strains of Haemophilus influenzae. Sixty strains of nontypeable H. influenzae which caused invasive disease or colonized the female urogenital tract were studied with monoclonal antibodies 7F3 and 4G4, which recognize different surface-exposed epitopes on the P6 molecule. All 60 strains expressed...

The ontogenetic development of postingestive inhibitory control of ingestion by the osmotic load of a preload was examined in rats. On postnatal days 6 (P6) and 12 (P12), pups were deprived for either 6 or 24 h. Gastric preloads (5% body wt) of water, mannitol (a sugar alcohol that is not absorbed) in six concentrations [from 0.125 M (hypotonic) to 1.0 M (hypertonic)], or sham preloads were adm...

Protein p6 of Bacillus subtilis bacteriophage Phi29 is essential for phage development. In vitro it activates the initiation of DNA replication and is involved in the early to late transcriptional switch. These activities require the formation of a nucleoprotein complex in which the DNA forms a right-handed superhelix wrapping around a multimeric protein core. However, there was no evidence of ...

OBJECTIVE To evaluate the effectiveness of acupressure applied at meridian P6 point for prevention of nausea and vomiting in patients undergoing laparoscopic cholecystectomy. METHODOLOGY A randomized double blind study was performed in 50 ASA I and II patients scheduled for laparoscopic cholecystectomy. Patients were divided into two groups; control and placebo. In the control group acupressu...

Aim. This study investigated the effect of P6 EA on droperidol-induced QTc interval prolongation and Cx43 expression in ventricular muscle of rats. Methods. Twenty-four rats were randomly divided into control group (C), droperidol group (D), or EA group (E). C group rats were injected with normal saline. D group rats were injected with droperidol 0.13 mg/kg. E group rats were pretreated with EA...

Given two graphs H1 and H2, a graph G is (H1,H2)-free if it contains no subgraph isomorphic to H1 or H2. Let Pt and Cs be the path on t vertices and the cycle on s vertices, respectively. In this paper we show that for any (P6, C4)-free graph G it holds that χ(G) ≤ 3 2 ω(G), where χ(G) and ω(G) are the chromatic number and clique number of G, respectively. Our bound is attained by several graph...

OBJECTIVE To compare the antiemetic effect of acupressure at the Neiguan point (P6) in a group of healthy women with normal pregnancy and nausea and vomiting during pregnancy (NVP) with a similar group receiving acupressure at a placebo point and another, similar group not receiving any treatment. STUDY DESIGN A randomized, placebo-controlled, pilot study involving 60 women. RESULTS It is p...

Let P6 denote the induced path on six nodes. We prove that if a perfect graph G contains P6 as an induced subgraph but not two families introduced by Conforti and Cornuéjols then G is bipartite or disconnected, or % G has a star cutset. r 2002 Elsevier Science (USA). All rights reserved.
