Some times, the mammary inferior breast pole can be affected in its thickness due to different causes such as merely overtime, oncology resections, implant exposure caused by infection, seromas, fistulas, etc. This paper describes a surgical alternative to provide a greater coverage in the inferior-internal quadrant of the breast, using a pectoral muscle flap in its distal position based on the irrigation by its internal perforating artery.

El polo inferior de la mama en ocasiones puede estar afectado en su espesor por diferentes causas, como el simple paso del tiempo, resecciones oncológicas, extrusiones protésicas por infección, seromas, fístulas, etc. Describimos en este trabajo una alternativa quirúrgica para brindar una mayor cobertura al cuadrante ínferointerno de la glándula mamaria, utilizando un colgajo de músculo pectoral en su porción distal, basado en la irrigación de sus perforantes internas.

The Co(II), Ni(II) and Cu(II) metal ions complexes of Bis(4-amino-5-mercapto-1,2,4-triazol-3-yl) alkanes (BATs) have been prepared and characterized by elemental analysis, conductivity measurements infrared, magnetic susceptibility, the electronic spectral data and thermal studies. Based on spectral and magnetic results, the ligands are tetradentate coordinating through the N and S-atoms of BATs; six-coordinated octahedral or distorted octahedral and some times four-coordinated square planar were proposed for these complexes. Activation energies computed for the thermal decomposition steps were compared. The ligands and their metal complexes were tested in vitro for their biological effects. Their activities against two gram-positive, two gram-negative bacteria and two fungal species were found to vary from moderate to very strong.
