The record of L. sceleratus in Spain consists the deepest (350-400m depth) record of the species in the Mediterranean Sea. The new records of native species include: first record of the ctenophore Cestum veneris in Turkish marine waters; the presence of Holothuria tubulosa and Holothuria polii in the Bay of Igoumenitsa (Greece); the first recorded sighting of the bull ray Pteromylaeus bovinus in Maltese waters; and a new record of the fish Lobotes surinamensis from Maliakos Gulf.

Objetivo: Describir las características de la prescripción del reposo médico de causa psiquiátrica en un servicio de atención especializado. Métodos: Se registraron las atenciones psiquiátricas y las licencias médicas emitidas en un período de 3 meses (julio a septiembre 2009). Resultados: En el período se realizaron 3.105 consultas psiquiátricas, indicándose licencia médica en 399 atenciones (12,7%). Se eliminaron 16 y se trabajó con 383 licencias. De estas, 184 (48%) fueron 1° licencia en el período, 190 (49,6%) fueron prórroga de anterior y 9 (2,3%) fueron repetición de reposo. El número de pacientes beneficiados con la indicación de reposo fue de 228 (12%). Los trastornos del ánimo dieron cuenta de un 78,1% de las licencias y se prescribieron más frecuentemente en mujeres (68,9%). La duración total del reposo fue 25,5 ± 20 días y la mediana fue 15. Discusión: En un servicio especializado de Psiquiatría las atenciones generaron 12,7% de prescripción de licencias médicas. La gravedad de los casos puede explicar la alta frecuencia de prórrogas y repetición de licencias. Los trastornos del ánimo son los diagnósticos más frecuentemente consignados como causa de la licencia médica. Este trabajo aporta datos técnicos sobre el uso y características de la licencia médica psiquiátrica en Chile. Objectives: To characterize sick leaves prescription in a specialized psychiatric service. Methods: We recorded all of psychiatric attentions as well as all of sick-leaves prescribed during a three months period (July to September, 2009). Results: 3,105 attentions were done, whit a 12,7% (399 attentions) of them resulting in a sick-leave prescription, corresponding to 228 out-patients. We discarded 16 sick-leaves because incomplete information. 184 (48%) sick-leaves were prescribed in a first visit, 190 (49,6%) were a prolongation of a previous sick-leave prescription, and 9 (2,3%) were prescribed after a working period posterior to a previous rest. Affective disorder were the most frequent diagnosis observed in sick-leave prescription (78,1%), being more frequent in women (68,9). The mean of rest was 25,5 ± 20 days with a median of 15 days. Discussion: A 12,7% of psychiatric attention generated a sick-leave prescription. Severity of disorders seen in a specialized psychiatric service could explain this finding. Our results confirm Affective Disorders are the principal cause of sick-leave prescription. This study add technical knowledge about feature and uses of psychiatric sick-leaves in Chile.

The present work reports on recent biodiversity records of Mediterranean native species such as Olindias phosphorica in the Turkish Aegean Sea and extended distribution of eleven alien species in the Mediterranean. These are: Bursatella leachi (Mollusca, Gastropoda: Algeria); Callinectes sapidus (Crustacea, Decapoda: Greek Ionian Sea); Caprella scaura (Crustacea, Amphipoda: Mar Piccolo of Taranto); Fistularia commersonii (Fish: Saronikos Gulf, Aegean Sea); Sphoeroides pachygaster (Fish: South Turkey); Musculista perfragilis (Mollusca, Bivalvia: South Turkey); Sepioteuthis lessoniana (Mollusca, Cephalopoda: central eastern coast of Tunisia); Flabellina rubrolineata (Mollusca, opisthobranchia: central Aegean, Greece); Hesionura serrata (Polychaeta: Apulian coast); Stephanolepis diaspros (Fish: Saronikos Gulf, Aegean Sea); and Parvocalanus crassirostris (Crustacea, Copepoda: Lesvos Island, Greek Aegean Sea).

Lipid and fatty acid compositions of Mytilus galloprovincialis cultured in the Mar Grande of Taranto (southern Italy): feeding strategies and trophic relationships. Zoological Studies 49(2): 211-219. Lipid and fatty acid (FA) compositions were determined in the mussel Mytilus galloprovincialis collected from June 2006 to May 2007 in the Mar Grande of Taranto, southern Italy. Total lipids significantly differed throughout the study period (ANOVA, p < 0.05), with higher values in summer (24.7% dry weight (DW)) and the lowest values in winter (3.5% DW). Triacylglycerols (TAGs) were the dominant lipid class in spring and summer accounting for 55.28% and 60.3% of total lipids, respectively, while in the autumn and winter phospholipids (PLs) were considerably greater than TAGs, comprising 55.16% and 47.5% of total lipids, respectively. Cholesterol did not show large variations over the seasons. Predominant FAs were saturated FAs (SAFAs) followed by monounsaturated FAs (MUFAs). The amount of polyunsaturated FAs (PUFAs) was low. The 14:0, 16:0, 18:0, and 22:0 SAFAs, together with 14:1, 16:1 omega 7, 18:1 omega 9, 18:1 omega 7, 20:1 omega 9, and 24:1 omega 9 MUFAs, and the PUFA, non-methylene interrupted dienoic (NMID), were the most abundant FAs. FA biomarkers are frequently used to identify trophic relationships among marine invertebrates. In order to obtain indications on food sources of M. galloprovincialis, a variety of FA ratios and the sum of some FAs were determined. The sum of 18:1 omega 7 + odd-branched FAs indicated a moderate bacterial contribution to the mussel diet. A high 18:1 omega 9/18:1 omega 7 ratio together with a high level of 20:1w9 indicated an animal dietary input. Trophic markers suggested lows contribution of diatoms and dinoflagellates to the diet of M. galloprovincialis.

During 2008 nine italian laboratories participating to Unichim working group performed five intercalibration ring tests considering embryotoxicity test with Mytilus galloprovincialis LMK. All research group worked with mussels from the same population (Gulf of Taranto). Results from four ring tests were statistically acceptable, determining the repeteability within laboratory and the reproducibility between laboratories.
