    Notes: Abstract Temperature and salinity affected both length of larval development and mortality inNecora puber collected in the Ría de A Coruña during December 1984 and January 1985. Development time decreased considerably with increased temperature. This decrease was sharper when temperature increased from 15° to 20°C than when it increased from 20° to 25°C. At 35‰S, average development took 48, 32 and 28 d at 15°, 20° and 25°C, respectively. At the three salinities tested (25, 30 and 35‰), larval development was completed only at 15°C, at 20°C/30 and 35‰S, and at 25°C/35‰S. Development times at 15° and 20°C were highly significantly different at both 35 and 30‰S (P ≪ 0.01). However, there were no significant differences between development times at 20° and 25°C (P 〉 0.05). Within any one specific temperature series, no significant difference was observed between the salinity values tested (P 〉 0.05). The duration of each of the five zoeal stages was similar within each and the same temperature/salinity combination, whereas the duration of the megalop was twice as long as any of the zoeal stages. The combination of the lowest temperature (15°C) and the highest salinity (35‰) tested resulted in the greatest larval survival of 28%. Highest mortality occurred at 25°C, at which temperature development was completed only at 35‰S. A sharp drop in larval survival was observed in the transition period Zoea V — megalop in all combinations of temperature and salinity tested. Within the limits of tolerance to temperature and salinity, the former effected more pronounced differences in the duration of larval development, while salinity appeared to constitute a limiting factor for survival.

    Notes: Resumen La estricnna inhibe competitivamente a la acetilcolinesterasa (AChE, acetilcolina acetil-hidrolasa, E.C. 3.1.1.7) y a la colinesterasa (ChE, acilcolina acilhidrolasa, E.C. 3.1.1.8) de cerebro de rata. Se calculó un ki de 7×10−5 M para AChE y de 1.7×10−4 M para ChE cuando sus actividades enzimáticas se midieron con acetilbetametilcolina y butirilcolina, respectivamente. Se analizó la relevancia de estos hallazgos para el mecanismo de acción de dosis altas de estricnina in vivo, concluyéndose que esta acción anticolinesterásica es de escasa importancia.

    Description / Table of Contents: Zusammenfassung In einer multizentrischen Studie wurden 588 Erwachsene mit nosokomialer Pneumonie, die nicht beatmungspflichtig waren, in 32 Krankenhäusern randomisiert entweder mit Cefotaxim allein oder der jeweils üblichen Kombinationstherapie behandelt. Nach demographischen Daten, Begleitkrankheit, Zusatztherapien und kausalem Erreger waren die beiden Gruppen vergleichbar. 40 der Patienten wurden wegen Protokollverletzung von der Auswertung bezüglich therapeutischer Wirksamkeit ausgeschlossen. Die Heilungsrate betrug in der Cefotaxim-Gruppe 79%, in der Vergleichsgruppe 71%. Dieser Unterschied ist statistisch signifikant (p=0,03, Fisher's two-tailed test). Bei Patienten, die mit einer Kombination aus einem vorwiegend gegen grampositive Erreger wirksamen Cephalosporin mit einem Aminoglykosid behandelt wurden, war die Heilungsrate sehr gering. Bei Behandlung mit den Antibiotikakombinationen traten signifikant mehr ernste Nebenwirkungen auf. Für die empirische Therapie der nosokomialen Pneumonie bietet die Behandlung mit Cefotaxim folglich bessere Möglichkeiten.
    Notes: Summary In a multicentre clinical trial involving 32 hospitals, 588 adult patients diagnosed with nosocomial pneumonia and not receiving mechanical ventilation were treated randomly with monotherapy with cefotaxime or the antibiotic combination routinely used in each particular hospital. Both groups of patients were similar regarding demographic data, concurrent diseases, additional therapies and causative organism. Protocol violations were recorded in 40 patients, and these patients were excluded from the evaluation of treatment efficacy. The cure rate was 79% in the cefotaxime group and 71% in the group receiving antibiotic combinations; this difference is statistically significant (p=0.03, Fisher's two-tailed test). In the patients receiving combinations of cephalosporins having activity predominantly against gram-positive organisms plus aminoglycosides, the cure rate obtained was very low. The frequency of serious adverse reactions was significantly higher in the group treated with antibiotic combinations. It is concluded that montherapy with cefotaxime is the regimen that offers better results for the empirical treatment of nosocomial pneumonia.

    Notes: Abstract Thalli of the economically important rhodophyteGelidium sesquipedale were cultured for 8 weeks under laboratory conditions, and the influence of temperature and photoperiod on the re-attachment process were studied. Four different temperatures (16, 18, 20, 22 °C) and four different photoperiods (6:18, 12:12, 14:10, 16:8) were used and the results obtained in the thalli responses such as apical growth (measured as elongation of principal apex), rhizoidal cluster production and number of necrotic patches were tested. During the re-attachment process, the best results were obtained at temperatures of 16–18 °C, when rhizoidal cluster production was high and necrotic patch development was low (18 °C) or absent (16 °C). Temperatures of 20 and 22 °C favoured high rhizoidal cluster production, but also a high production of necrotic patches that finally led to death. The results suggest that long-day photoperiods (14:10, 16:8) produce a higher number of rhizoidal cluster bands than short-day photoperiods (6:18) at the same temperature.

    Description: We review current knowledge and understanding of the biology and ecology of the calanoid copepod Calanus helgolandicus in European waters, as well as provide a collaborative synthesis of data from 18 laboratories and 26 sampling stations in areas distributed from the northern North Sea to the Aegean and Levantine Seas. This network of zooplankton time-series stations has enabled us to collect and synthesise seasonal and multi-annual data on abundance, body size, fecundity, hatching success and vertical distribution of C. helgolandicus. An aim was to enable comparison with its congener Calanus finmarchicus, which has been studied intensively as a key component of European and north east Atlantic marine ecosystems. C. finmarchicus is known to over-winter at depth, whereas the life-cycle of C. helgolandicus is less well understood. Overwintering populations of C. helgolandicus have been observed off the Atlantic coast between 400 and 800 m, while in the Mediterranean there is evidence of significant deep-water populations at depths as great as 4200 m. The biogeographical distribution of C. helgolandicus in European coastal waters covers a wide range of habitats, from open ocean to coastal environments, and its contribution to mesozooplankton biomass ranges from 6% to 93%. Highest abundances were recorded in the Adriatic and off the west coast of Spain. C. helgolandicus is generally found in 9–20 °C water, with maximum abundances from 13–17 °C. In contrast, C. finmarchicus is found in cooler water between 0 and 15 °C, with peak abundances from 0 to 9 °C. As water has warmed in the North Atlantic over recent decades, the range of C. helgolandicus and its abundance on the fringes of its expanding range have increased. This review will facilitate development of population models of C. helgolandicus. This will not only help answer remaining questions but will improve our ability to forecast future changes, in response to a warming climate, in the abundance and distribution of this important species.
