PAHs analysis of fish whole gall bladders and livers from the Natural Reserve of Camargue by GC/MS.

Traces of parent polycyclic aromatic hydrocarbons (PAH) in fish whole gall bladders and livers from the Natural Reserve of Camargue were determined from three different species: cels, goldfishes and catfishes by capillary gas chromatography-mass spectrometry (GC/MS) after Soxhlet extraction and florisil column cleanup. Results have been successfully correlated with biological fish parameters in order to identify adequate biomarkers of PAHs contamination.

Contrasting behavior of tetracene and perylene in collision-induced dissociation: a theoretical interpretation.

Dimethyl ether chemical ionization mass spectrometry of polycyclic aromatic hydrocarbons (PAHs) leads to [M + 13](+) and [M + 45](+) ions. The process leading to these ions is sensitive to the proton affinity of the PAH. Collision-induced dissociation observations on [M + 45](+) ion also show that tetracene has a peculiar reactivity in comparison with perylene, despite the similar physico-chemical properties of these two molecules. Ab initio calculations were used to establish a potential energy profile for the mechanistic pathway of [M + 13](+) and [M + 45](+) formation. [M + 45](+) ions result from the addition of CH(3)-O-CH(2)(+) to PAHs. A 1,2-hydride transfer followed by a 1,4-proton transfer and a loss of methanol subsequently lead to the formation of [M + 13](+) ions. For tetracene, the 1,2-hydride transfer does not occur, as it would lead to a thermodynamically unstable non-planar ion.

[Reconstructive methods of the antero-lateral thoracic wall after extensive surgery of invasive tumors].

Local recurrence after conservative or enlarged surgery for breast carcinoma, or primary chest wall's tumors should first be approached surgically, chimio- and radiotherapy being used only later on. A precise local and general evaluation has to be made first, trying to determine whether there is or not an invasion of bony structures. When they are free of tumor, regional transfer of musculocutaneous flaps can usually cover the defect (latissimus dorsi, 1-2 rectus abdomini, pectoralis major); great omentum is used when this defect is too large. When ribs, sternum or deep structures are invaded, reconstruction uses successively: a mersilene mesh, bone cement, an omental flap covered with mesh skin grafts 2 days later. Surgical management of these difficult situations is most of the time only a palliative measure which gives these patients a better quality of life for the short time they still have got.
