Mesh size and effort changes in multispecies fisheries in ICES Divisions Vlllc and IXa.
Different simulations varying trawl mesh size and effort changes
for several fishing units in ICES Divisions VIllc and IXa were
carried out. Landings included in the analysis represent most of
the catches in the southern area defined as the management unit
for hake, megrim; monkfish, horse mackerel, blue whiting and
mackerel. Three Nephrops stock s in Divisions Vlllc and IXa are
also included. These species are mainly exploited by Spanish and
Portuguese fleets, using various fishing gears to exploit
different fractions of the populations, and for this reason nine
fishing units were used in the analysis
Cambios de malla y esfuerzo en las pesquerías multiespecíficas en aguas atlánticas de la península Ibérica
Se han realizado diferentes ensayos de cambios de malla y esfuerzo para varias unidades
pesqueras de las divisiones VIIIc y IXa del CIEM (Consejo Internacional pqra la
Exploración del Mar). Los desembarcos incluidos en este análisis representan la mayoría
de las capturas de las especies de merluza, gallos, rapes, jurel, lirio y caballa en la zona
sur, definida como unidad de gestión. Están también incluidos tres stocks de cigala de estas
divisiones. Dichas especies son las principales especies explotadas por las flotas española
y portuguesa, que usan diferentes tipos de artes para explotar diferentes fracciones de
las poblaciones. Por esta razón en el presente análisis se utilizaron nueve unidades pesqueras.Different simulations varying trawl mesh size and effort changes for several fishing

Cut-offs and response criteria for the Hospital Universitario la Princesa Index (HUPI) and their comparison to widely-used indices of disease activity in rheumatoid arthritis
Objective To estimate cut-off points and to establish response criteria for the Hospital Universitario La Princesa Index (HUPI) in patients with chronic polyarthritis. Methods Two cohorts, one of early arthritis (Princesa Early Arthritis Register Longitudinal PEARL] study) and other of long-term rheumatoid arthritis (Estudio de la Morbilidad y Expresión Clínica de la Artritis Reumatoide EMECAR]) including altogether 1200 patients were used to determine cut-off values for remission, and for low, moderate and high activity through receiver operating curve (ROC) analysis. The areas under ROC (AUC) were compared to those of validated indexes (SDAI, CDAI, DAS28). ROC analysis was also applied to establish minimal and relevant clinical improvement for HUPI. Results The best cut-off points for HUPI are 2, 5 and 9, classifying RA activity as remission if =2, low disease activity if >2 and =5), moderate if >5 and <9 and high if =9. HUPI''s AUC to discriminate between low-moderate activity was 0.909 and between moderate-high activity 0.887. DAS28''s AUCs were 0.887 and 0.846, respectively; both indices had higher accuracy than SDAI (AUCs: 0.832 and 0.756) and CDAI (AUCs: 0.789 and 0.728). HUPI discriminates remission better than DAS28-ESR in early arthritis, but similarly to SDAI. The HUPI cut-off for minimal clinical improvement was established at 2 and for relevant clinical improvement at 4. Response criteria were established based on these cut-off values. Conclusions The cut-offs proposed for HUPI perform adequately in patients with either early or long term arthritis

The comparative responsiveness of Hospital Universitario Princesa Index and other composite indices for assessing rheumatoid arthritis activity
Objective
To evaluate the responsiveness in terms of correlation of the Hospital Universitario La Princesa Index (HUPI) comparatively to the traditional composite indices used to assess disease activity in rheumatoid arthritis (RA), and to compare the performance of HUPI-based response criteria with that of the EULAR response criteria.
Methods
Secondary data analysis from the following studies: ACT-RAY (clinical trial), PROAR (early RA cohort) and EMECAR (pre-biologic era long term RA cohort). Responsiveness was evaluated by: 1) comparing change from baseline (Delta) of HUPI with Delta in other scores by calculating correlation coefficients; 2) calculating standardised effect sizes. The accuracy of response by HUPI and by EULAR criteria was analyzed using linear regressions in which the dependent variable was change in global assessment by physician (Delta GDA-Phy).
Results
Delta HUPI correlation with change in all other indices ranged from 0.387 to 0.791); HUPI's standardized effect size was larger than those from the other indices in each database used. In ACT-RAY, depending on visit, between 65 and 80% of patients were equally classified by HUPI and EULAR response criteria. However, HUPI criteria were slightly more stringent, with higher percentage of patients classified as non-responder, especially at early visits. HUPI response criteria showed a slightly higher accuracy than EULAR response criteria when using Delta GDA-Phy as gold standard.
Conclusion
HUPI shows good responsiveness in terms of correlation in each studied scenario (clinical trial, early RA cohort, and established RA cohort). Response criteria by HUPI seem more stringent than EULAR''s
Spanish selectivity experiments in region 3
In this paper a preliminary revision of selectivity experiments achieved by Spanish scientists in
Region 3 is presented. The species analysed were hake, blue whiting, Norway lobster, horse
mackerel and megrim. In most ofthem polyamide gears were used, with the exception of a few
(and old) cases with polyethylene gears. The selectivity data included in this revision were
obtained in a range of years since 1968 to 1985, and the majority of them were obtained by
Robles et al in 1985. All the experiences were carried out using single twine and cover codend,
using research vessels. Any attempt to obtain selectivity parameters under cornmercial fishing
conditions was not made in this area by Spanish scientist
Studies on the reproductive and developmental biology of Cichlasoma dimerus (Percifomes, Cichlidae
Many characteristics of the South American teleost fish Cichlasoma dimerus (body size, easy breeding, undemanding maintenance) make it amenable to laboratory studies. In the last years, many of the fundamental aspects of its reproductive and developmental biology have been addressed in our laboratory. Rather recently, the immunohistochemical localization of pituitary hormones involved in reproduction and in background color adaptation has been described in both adult and developing individuals, and the role of FSH in ovarian differentiation has been established. These findings have been correlated with mapping of some of their brain-derived controlling hormones. The latter include brain-derived gonadotropins which were shown to be active in vitro in the control of pituitary hormone secretions. The emerging picture shows C. dimerus as an interesting species in which many of their basic features have already been investigated and which conform a solid platform for comparative studies correlating neurohormones, pituitary hormones and behavior, from the molecular to the organismic level.Fil:Pandolfi, M.
