Histological investigation on the ovarian cycle of the bluefin tuna in the western and central Mediterranean
The histological analysis of eastern Atlantic bluefin tuna Thunnus thynnus ovaries caught from February to September 1999-2000, made it possible to distinguish the presence of seven oocyte… Expand
Evidence of a spawning area for the bluefin tuna (Thunnus thynnus L.) in the eastern Mediterranean
Deleted in malignant brain tumor 1 is secreted in the oviduct and involved in the mechanism of fertilization in equine and porcine species.
It is shown that oviductal fluid induces an increase in the monospermic fertilization rate and that this effect is canceled by the addition of antibodies, in both porcine and equine species. Expand
Evidence of a high percentage of intersex in the Mediterranean swordfish (Xiphias gladius L.).
The first evidence of the presence of intersexuality in a wild population of Mediterranean swordfish (Xiphias gladius L.) is reported and vitellogenin was demonstrated immunohistochemically in the liver of both intersex and normal males. Expand
Size and age at sexual maturity of female bluefin tuna (Thunnus thynnus L. 1758) from the Mediterranean Sea
The reported evidence indicates that for the eastern Atlantic bluefin tuna stock, the size and age of first sexual maturity of females was lower than in the western Atlantic stock. Expand

It is suggested that phospholipase production might act in synergism with the biofilm formation by inducing or exacerbating skin lesions in dogs, toward revealing the pathogenicity of M. pachydermatis in animals. Expand
Immunohistochemical localization of CYP1A, vitellogenin and Zona radiata proteins in the liver of swordfish (Xiphias gladius L.) taken from the Mediterranean Sea, South Atlantic, South Western Indian…
Findings confirm previous findings about the potential exposure of Mediterranean swordfish to endocrine, disrupting chemicals and raise questions concerning the possible presence of xenobiotic contaminants off the Southern coasts of South Africa in both the South Atlantic and South Western Indian Oceans.

Histochemical analysis of lizard testicular glycoconjugates during the annual spermatogenetic cycle.
In the testis of lizard, the two spermatogenesis periods show the emergence of different types of glycosylation, including O-linked sialylgalactosyl glycans and N-linked glycans terminating in beta-galactOSyl residues. Expand

The regional difference in the carbohydrate components of the ductus epididymis epithelium of a lizard was delineated by means of 13 lectins by showing all the investigated carbohydrates in their peripheral zone except terminal βGalNAc and Fuc, whereas internal Man/Glc and terminal Gal were expressed in the central core.

The immunohistochemical analyses revealed that the initial internalisation of hepatic zona radiata proteins (Zrp) in the swordfish oocyte starts before the uptake of vitellogenin (Vtg) and that a significant E2 increase in plasma is associated with the beginning of Vtg uptake, confirming the hypothesis that the differential and sequential induction of zonagenesis and viteLLogenesis may reflect a general feature of teleost oogenesis.
