Rate of protein synthesis in oocytes of Paracentrotus lividus
Developmental Biology, 1976Abstract The rate of protein synthesis of Paracentrotus lividus oocytes in comparison with the rate in unfertilized eggs and embryos has been analyzed, both in vivo and after oocyte and egg isolation. It is suggested that oocytes synthesize proteins at the same rate as unfertilized eggs.

Antibacterial activity in the coelomocytes of the sea urchin Paracentrotus lividus
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1996Naturally present antibacterial activity directed against Vibrio alginolyticus was demonstrated in coelomocytes lysate (CL) and cell-free coelomic fluid (CF) of the marine echinoderm Paracentrotus lividus. Kinetic analysis revealed that 5 min of contact was enough to induce significant bactericidal effect.

EGFR signalling is required for Paracentrotus lividus endomesoderm specification
Archives of Biochemistry and Biophysics, 2008The EGFR pathway is critical for cell fate specification throughout the development of several organisms. Here we identified in sea urchin an EGFR-related antigen maternally expressed and showing a dynamic pattern of localization during development. To investigate the role played by the EGFR in Paracentrotus lividus development we blocked its activity ...

Binding properties of Paracentrotus lividus (Echinoidea) hemolysin
Comparative Biochemistry and Physiology Part A: Physiology, 19911. Paracentrotus lividus hemolysin binds erythrocytes, zymosan particles, lipopolysaccharide and laminarin surfaces but not auto and allogeneic cell membranes. 2. The binding could, at least for erythrocytes, involve phospholipids and cholesterol. 3. The protease activity of the coelomic fluid is not related to hemolysis. 4.

Embryotoxicity of butyltin compounds to the sea urchin Paracentrotus lividus
Marine Environmental Research, 2000Tributyltin (TBT) has been widely employed in marine anti-fouling paints as a biocide, although it represents a serious risk, particularly in estuarine and coastal water/sediment ecosystems. In this study, the embryotoxic effects of TBT and its degradation products, dibutyltin (DBT) and monobutyltin (MBT), were analyzed during the development of the ...

Occurrence of Paracentrotus lividus (Lamarck) in Scotland
Nature, 1954Paracentrotus lividus is a littoral sea-urchin well known in the Mediterranean and on the Atlantic coasts of Europe. In the British Isles it has been recorded only in Ireland, where it is common on the south and west coasts, and occasionally in Devonshire and Cornwall1.

Food allergy to Paracentrotus lividus (sea urchin roe)
Annals of Allergy, Asthma & Immunology, 2007Sea urchins are increasingly used as culinary products in Japanese and Korean cuisine throughout the world.To investigate a possible IgE-mediated allergy in a patient who experienced an anaphylactic reaction after eating sea urchin roe and mussels.A 40-year-old man experienced generalized pruritus and urticaria, shortness of breath, and wheezing 10 ...

Clustering of tRNA genes in Paracentrotus lividus mitochondrial DNA
Current Genetics, 1988We have determined the base sequence of the restriction fragment Bam1-2 (3,593) of Paracentrotus lividus (sea urchin) mtDNA. This fragment contains, in addition to genes previously identified (part of the 12S rRNA, ND1 and part of the ND2 mRNA), a cluster of 15 tRNA genes located between the 12S and ND1 genes. Also to be found in the tRNA gene cluster,

Standardizing the Methodology of Sperm Cell Test with Paracentrotus Lividus
Environmental Monitoring and Assessment, 2006The sperm cell toxicity test with Paracentrotus lividus is widely used in Italy to assess the quality of complex aqueous matrices, but at present there is a shortage of standardized methodologies for the bioassay performance. In this work several critical points were considered, in order to verify the reliability of this bioassay and to improve its ...

A novel gene order in the Paracentrotus lividus imtochondrial genome
Gene, 1987The mitochondrial DNA (mtDNA) from Paracentrotus lividus (sea urchin) eggs, a circular molecule of about 15,500 bp, has been cloned in plasmid vectors after cleavage with various restriction enzymes. By a combination of Northern blot hybridization and nucleotide sequence analysis we have characterized most of the P.
