Context: The star cluster R136 inside the LMC hosts a rich population of massive stars, including most stars known. strong stellar winds these very luminous impact their evolution and surrounding environment. We currently lack detailed knowledge wind structure that is needed to quantify this impact. Aims: To observationally constrain properties in R136, particular parameters related clumping. M...

BACKGROUND AND PURPOSE Several white matter tracts in the brain cannot be identified on MR studies because they are indistinguishable from the surrounding white matter. We sought to develop a method to precisely localize white matter tracts by correlating anatomic dissections with corresponding MR images. METHODS MR imaging was used to guide anatomic dissection of the uncinate fasciculus. For...

OBJECTIVE To explore how important is the number of pelvic lymph nodes dissected for the nodal staging in FIGO IA2-IB2 cervical cancer, submitted to radical surgical treatment. METHODS A cross-sectional study was carried out on patients who underwent Piver class II radical hysterectomy and pelvic lymphadenectomy, in two centers in the state of Pernambuco, from January, 2001 to December, 2008....
