Length-weight relationships for bluefin tuna (Thunnus thynnus L.) caught from the Lybian trap fishery in 1999-2002
This paper reports length-weight relationships for the bluefin tuna (Thunnus thynnus L.) in the
Mediterranean. The estimated equations that are based on data from the Libyan trap fishery
during 1999 to 2002, allow conversions from fork length to round weight.Le présent document fournit una série de rapports

Intraoperative radiotherapy in the multidisciplinary treatment of bone sarcomas in children and adolescents
From September 1984 to December 1989, 38 patients of pediatric age with localized bone sarcomas received intraoperative radiotherapy (IORT) as part of a multidisciplinary treatment program. The age ranged from 6 to 21 years. The tumor histologies were 22 osteosarcomas and 16 Ewing's sarcomas. Thirty-four had initial primary disease (90%) and 4 were treated for local recurrence (10%). IORT was used on 32 untreated patients and in 6 previously treated with external beam radiotherapy (EBR). The IORT field included the surgically exposed tumor bed area. Single radiation doses ranging from 10 to 20 Gy were delivered, using 6-20 MeV electron beams. The median follow-up time for the entire group is 25 months (2-65+ months). The projected 5-year disease-free and overall survival rates are 65% and 69%, respectively. One patient developed a local recurrence in each histological group: one chondroblastic osteosarcoma and one cervical Ewing's sarcoma. Six patients died from metastatic progression: 3 initially recurrent tumors and three primary disease cases. Severe neuropathy and soft tissue necrosis were seen in some patients as IORT related complications. IORT is a feasible technique to be integrated in multidisciplinary programs that may promote local control in pediatric and adolescent patients with bone sarcomas. Peripheral nerves are dose-limiting tissue structures for IORT
Contribution of microscopy for understanding the mechanism of action against trypanosomatids
Transmission electron microscopy (TEM) has proved to be a useful tool to study the ultrastructural alterations and the target organelles of new antitrypanosomatid drugs. Thus, it has been observed that sesquiterpene lactones induce diverse ultrastructural alterations in both T. cruzi and Leishmania spp., such as cytoplasmic vacuolization, appearance of multilamellar structures, condensation of nuclear DNA, and, in some cases, an important accumulation of lipid vacuoles. This accumulation could be related to apoptotic events. Some of the sesquiterpene lactones (e.g., psilostachyin) have also been demonstrated to cause an intense mitochondrial swelling accompanied by a visible kinetoplast deformation as well as the appearance of multivesicular bodies. This mitochondrial swelling could be related to the generation of oxidative stress and associated to alterations in the ergosterol metabolism. The appearance of multilamellar structures and multiple kinetoplasts and flagella induced by the sesquiterpene lactone psilostachyin C indicates that this compound would act at the parasite cell cycle level, in an intermediate stage between kinetoplast segregation and nuclear division. In turn, the diterpene lactone icetexane has proved to induce the external membrane budding on T. cruzi together with an apparent disorganization of the pericellar cytoskeleton. Thus, ultrastructural TEM studies allow elucidating the possible mechanisms and the subsequent identification of molecular targets for the action of natural compounds on trypanosomatids.Fil: Lozano, Esteban Sebastián.

Movements, Habitat Use, and Diving Behavior of Shortfin Mako in the Atlantic Ocean
The shortfin mako is one of the most important shark species caught in Atlantic Ocean
pelagic fisheries. Given increasing concerns for the stock status of the species, the
present study was designed to fill gaps in the knowledge of habitat use and movement
patterns of shortfin mako in the Atlantic Ocean. From 2015 to 2019, 53 shortfin makos
were tagged with pop-up satellite archival tags within the North, Central, and Southwest
Atlantic Ocean, with successful transmissions received from 34 tags. Generally, sharks
tagged in the Northwest and Central Atlantic moved away from tagging sites showing
low to no apparent residency patterns, whereas sharks tagged in the Northeast and
Southwest Atlantic spent large periods of time near the Canary Archipelago and
Northwest Africa, and over shelf and oceanic waters off southern Brazil and Uruguay,
respectively. These areas showed evidence of site fidelity and were identified as possible
key areas for shortfin mako. Sharks spent most of their time in temperate waters (18–
22◦C) above 90 m; however, data indicated the depth range extended from the surface
down to 979 m, in water temperatures ranging between 7.4 and 29.9◦C. Vertical
behavior of sharks seemed to be influenced by oceanographic features, and ranged
from marked diel vertical movements, characterized by shallower mean depths during
the night, to yo-yo diving behavior with no clear diel pattern observed. These results
may aid in the development of more informed and efficient management measures for
this species.En prens
