    Notes: Abstract Specimens of Spirographis spallanzani (Polychaeta: Sabellidae) were collected in the Gulf of Taranto, Italy, in 1991, and their mucous secretion was examined. The mucus possesses thermolabile biologically active proteins which produce hemolysis in vertebrate erythrocytes. The molecules are ineffective against both unfertilized and fertilized echinoid eggs and spermatozoa. The lytic reaction against rabbit erythrocytes varies as a function of cations, pH and temperature, and displays a fast time-course. No immunological cross-reaction could be demonstrated between hemolysins of S. spallanzani and Eisenia foetida andrei. SDS-PAGE analysis of mucus proteins reacting with sheep erythrocytes revealed that at least three major (16, 22 and 40 kDa) and two minor (29 and 34 kDa) components interact with membrane targets.

    Notes: Abstract Hemolytic capacity was investigated in homogenates of eight species of polychaetes, belonging to five different orders.Nainereis laevigata, Orbinia cuvieri, Cirriformia tentaculata, Notomastus latericeus, Arenicola claparedii andPetaloproctus terricola were collected during February 1990 from the coastal lagoon of Acquatina (Puglia, Italy).Nereis sp. (from the Yellow Sea, Japan) andMarphysa sanguinea (from Venice lagoon, Italy) were both purchased from a retail shop in Lecce (Italy). Homogenates from only three species [Nainereis laevigata andO. cuvieri (family Orbinidae, order Orbinia) andP. terricola (family Maldanidae, order Capitellida)] induced hemolysis in sheep red blood cells. Important differences in hemolytic titers, Ca- or Mg-dependence and in timecourse responses were noted between the three hemolytic species. On the other hand, thermolability and proteinase-inhibitor resistance (with the exception ofO. cuvieri) were features common to all three. Electrophoretic analysis revealed that hemolysis was mediated by apparently only one protein inN. laevigata andP. terricola, with no correlation between them or with the proteins responsible for hemolysis in the oligochaeteEisenia fetida andrei (Lumbricidae). No lytic protein was localized in hemolyticO. cuvieri homogenate, which was also the only homogenate to be partially inhibited by benzamidine, but not by phenylmethylsulfonyl fluoride or soybean trypsin inhibitor. These results underline the extreme variety existing among the species constituting the polychaete group.

    Notes: Abstract Isoelectric focussing (IEF) in carrier ampholyte-generated pH gradients and hybrid isoelectric focussing (HIEF) in immobilized pH gradients under nondenaturing conditions were used in parallel to screen 5,500 plasma samples for naturally occurring variants of apolipoprotein A-I (apo A-I). The following defects were identified in four unrelated subjects heterozygous for apo A-I variants: apo A-I(ΔK107)(2 ×), apo A-I(K107M)(1 ×), and apo A-I(E41R)(1 ×). The later variant is a novel finding. Family studies did not reveal any association of apo A-I(K107M) and apo A-I(E41R) with dyslipidemia, but identified several heterozygotes for apo A-I(ΔK107) who had low levels of high density lipoprotein (HDL)cholesterol. Therefore, and since the apo A-I(ΔK107) is the most frequent apo A-I variant in Germany (1 ∶ 5,000) we evaluated our data and that reported from 11 families with 32 heterozygous carriers and 30 unaffected controls. This analysis revealed that apo A-I(ΔK107) is associated with lower HDL-cholesterol (-30%) and higher triglycerides (+ 48%) in men but not in women as compared with unaffected family members as well as with controls from the Prospective Cardiovascular Münster (PROCAM) study. Moreover, 11 of 15 male apo AI(ΔK107) heterozygotes but only 2 of 17 female apo AI(ΔK107) heterozygotes had HDL-cholesterol levels below the 20th percentile of sex-matched controls from the PROCAM study. We conclude that heterozygosity for apo A-I(ΔK107) decreases HDL-cholesterol and increases triglycerides in men but not in women.

    Notes: Abstract A novel, hyperthermophilic, anaerobic, sulfurmetabolizing archaeon was isolated from a fluid sample from recently discovered hydrothermal vents in the North Fiji basin (SW Pacific), at 2000 m depth. The new organism, strain GE5, is a gram-negative, highly motile coccus. It grows between 67° and 102°C under atmospheric pressure, with an optimum at 96°C (doubling time 33 min). The upper growth temperature is extended by at least 3°C when cells are cultivated under in situ hydrostatic pressures (20 MPa). Strain GE5 is an obligate heterotroph, fermenting peptides, or mixtures of amino acids to acetate, isovalerate, isobutyrate, propionate, H2 and CO2. Hydrogen inhibits growth unless sulfur is present. In the presence of sulfur, H2S is then produced. Phylogenetic analyses of the 16 S rRNA sequence of strain GE5 places the new isolate within the Thermococcales. By its high growth temperature and physiological features the new isolate ressembles Pyrococcus sp. However it deffers by a 7% mol upper G+C-content and shows low level of DNA similarity with the two previously described species. Based on these differences the description of strain GE5 as a new species Pyrococcus abyssi (CNCM I-1302) is proposed.

    Notes: This paper investigated three factors, two related to accountability and one an individual difference factor, which may influence rating level: (1) identifiability, (2) to whom one feels accountable (audience), and (3) conscientiousness. In study 1, results from students who rated their instructors indicated that not only did raters relatively high in conscientiousness report feeling more accountability but also that identifiability and conscientiousness interacted in predicting rating level. Raters relatively low in conscientiousness provided higher ratings when identified but raters relatively high in conscientious did not provide higher ratings. Rating audience did not influence rating level. Study 2 replicated the findings from study 1: Low conscientious raters assigned higher ratings when identified than when anonymous but high conscientious raters did not assign higher ratings when identified. Implications are discussed.

    Notes: Purpose - Managers frequently complain that performance ratings are inflated; thus, this study aims to explore what extent two motivational factors theoretically associated with accountability, rating audience and incentive, can influence rating inflation. Design/methodology/approach - One hundred and forty-nine raters were assigned to one of four audience conditions (ratee, expert, both ratee and expert - dual, and no audience) and either to an incentive or no incentive condition. Findings - Results showed that when an incentive was offered, raters expecting an expert audience to view their ratings provided significantly lower ratings, and raters expecting a dual audience provided significantly higher ratings compared to raters not offered an incentive. Furthermore, raters expecting a ratee audience inflated their ratings, regardless of incentive. Research limitations/implications - Financial incentives were used in this study and more research is needed to explore other types of incentives. Nonetheless, this research shows that incentives influence rating level. Practical implications - The research suggests that if managers wish to reduce rating inflation, they should ensure that an audience, other than the person being rated, will view the ratings. Originality/value - This study is the first to show that feelings of accountability and rating level are influenced by incentives, and that the audience of the ratings can determine whether incentives result in lower or higher ratings. Furthermore, it appears that the tendency to inflate ratings given a ratee audience may be quite powerful, even in the absence of specific incentives.
