BACKGROUND Immature teratoma (IT) is a tumor containing immature neuroectodermal tissue, primarily in the form of neuroepithelial tubules. However, the diagnosis of tumors containing only cellular neuroglial tissue (CNT) without distinct neuroepithelial tubules is often difficult, since the histological characteristics of immature neuroectodermal tissues remain unclear. Here, we examined the si...

B6D2F1 mice received cobalt-60 radiation on day 10.5 of gestation at doses of 50 to 300 rad at a dose rate of 40 rad per min. These animals were studied at four selected age periods: (a) day 14.5 of gestation, (b) neonate, (c) juvenile, and (d) 13 week-old adult. Fetal liver cellularity, morphology, and hemopoietic progenitor cell concentration reflected injury after 200 rad. The 15 day-old mou...

Let E be an n -dimensional vector space. Then the symmetric group Sym ( ) acts on by permuting elements of a basis and hence r -fold tensor product ? . Bowman, Doty Martin ask, in [1] , whether endomorphism algebra End is cellular. The module permutation for certain Young -set. We shall show that arbitrary -set cellular algebra. determine, terms point stabilisers which appear, when quasi-heredi...

OBJECTIVE To evaluate the diagnostic usefulness of cerebral spinal fluid (CSF) cellularity, protein, neutrophils, glucose and lactate for detection of postoperative bacterial meningitis. METHOD This prospective study was conducted in 28 postoperative neurosurgical patients from 2002 to 2005 at University of São Paulo. The CSF markers were plotted in a receiver operating characteristic (ROC) c...

OBJECTIVES The purpose of this pictorial review is to present the imaging spectrum of renal oncocytomas with radiological-pathological correlation. CONCLUSION The differences in tumour cellularity (high cellularity or low cellularity with abundant stroma) and haemorrhagic/cystic change contribute to a wide spectrum of imaging findings of renal oncocytomas. Imaging findings substantially overl...
