On heating pure, fully saturated 2,3-diacyl-DL-phosphatidyl-ethanolamines and 2,3-diacylphosphatidyl-cholines (lecithins) in water to the transition temperature at which large endothermic heat changes occur, they are observed, by light microscopy, to form myelin figures. This result is discussed in terms of the large difference in the transition temperature for "melting" of the hydrocarbon chai...

Differential diagnosis of trichoepithelioma (TE) and basal cell carcinoma (BCC) on the basis of clinical symptoms and laboratory investigations may be difficult in certain patients. The aim of the present study was to compare cluster of differentiation 10 (CD10) and androgen receptor (AR) expression patterns in BCC and TE, to investigate the predictive power of these proteins as markers of the ...

PURPOSE Molecular factors involved in apoptosis may affect breast cancer response to chemotherapy. Herein, we studied the nuclear factor kappaB (NF-kappaB)/bcl-2 pathway to determine whether or not activation of this antiapoptotic pathway was associated with a poor response of human breast cancer to anthracycline-based neoadjuvant chemotherapy. EXPERIMENTAL DESIGN We studied 82 human breast c...

BACKGROUND High frequencies of the BRAF V600E mutation have been reported in pleomorphic xanthoastrocytoma (PXA). Recently, a BRAF V600E mutation-specific antibody has been developed and validated. We evaluated the immunohistochemical (IHC) detection of BRAF V600E mutation in PXA by comparing to gold standard molecular analysis and investigating the interobserver variability of the IHC scoring....
