- The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions. A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon. Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities. PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution. The detector consists of a large number of subsystems that are discussed in other papers in this volume. The overall design parameters of the detector are presented. (C) 2002 Elsevier Science B.V.

- Salivary agglutinin is a high molecular mass component of human saliva that binds Streptococcus mutans, an oral bacterium implicated in dental caries. To study its protein sequence, we isolated the agglutinin from human parotid saliva. After trypsin digestion, a portion was analyzed by matrix-assisted laser/desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), which gave the molecular mass of 14 unique peptides. The remainder of the digest was subjected to high performance liquid chromatography, and the separated peptides were analyzed by MALDI-TOF/post-source decay; the spectra gave the sequences of five peptides. The molecular mass and peptide sequence information showed that salivary agglutinin peptides were identical to sequences in lung (lavage) gp-340, a member of the scavenger receptor cysteine-rich protein family. Immunoblotting with antibodies that specifically recognized either lung gp-340 or the agglutinin confirmed that the salivary agglutinin was gp-340. Immunoblotting with an antibody specific to the sialyl Le(x) carbohydrate epitope detected expression on the salivary but not the lung glycoprotein, possible evidence of different glycoforms. The salivary agglutinin also interacted with Helicobacter pylori, implicated in gastritis and peptic ulcer disease, Streptococcus agalactiae, implicated in neonatal meningitis, and several oral commensal streptococci. These results identify the salivary agglutinin as gp-340 and suggest it binds bacteria that are important determinants of either the oral ecology or systemic diseases.

- Objective To determine the effect of ONO-8815Ly on uterine contractions. Design A randomised, double-blind, placebo-controlled, dose-ascending, cross-over study. Setting Department of Obstetrics and Gynaecology, University Hospital of Lund, Sweden. Population Seventeen, healthy, parous and permanently sterilised women. Methods Intrauterine pressure was recorded on days 1-3 of bleeding of two menstruations. Subjects were intravenously treated with 4 or 8 mug/minute of ONO-8815Ly or placebo for 130 minutes. Intravenous bolus injections of oxytocin, 50 pmol/kg body weight, were given 10 minutes before, during infusion after 60 and 120 minutes and 60 minutes after completion of infusion. The plasma concentrations of ONO-8815Ly were measured in samples obtained immediately before each oxytocin injection. Main outcome measure Area under pressure recording curve (AUC) 10 minutes before and after each oxytocin injection. Results Twelve women, six in each dose group, completed both recordings. Of these, two women of each group were not included in efficacy analysis due to non-responsiveness to oxytocin or missing baseline value. The AUC over 10 minutes before oxytocin injection after 60 minutes of infusion of ONO-8815Ly at 4 and 8 mug/minute was reduced to 21% and 37% of that before infusion, respectively. The AUC after oxytocin at that time amounted to 21% and 19%, respectively, of that before infusion. The activity and responsiveness remained low after 120 minutes but started to return to baseline 60 minutes after stopping infusion. Placebo had no effect. Conclusions ONO-8815Ly is a potent inhibitor of spontaneous uterine contractility in non-pregnant women and it reduces the uterine response to oxytocin injections.
