Mammary adipose tissue is an important source of paracrine mitogens and anti-mitogens, including insulin-like growth factor, transforming growth factors, and cytokines (especially, TNFalpha and IL-1beta). Nevertheless, it is also an important source of the adipocytokine, leptin. Recently, leptin was reported to stimulate the proliferation of various cell(More)
Gene amplifications in the q13 band of chromosome 11 are among the most frequent genetic alterations in head and neck squamous cell carcinomas. Previous studies have suggested that such amplification is a marker of aggressive tumor evolution. Their potential for predicting subclinical lymph node invasion or disease recurrence was investigated in a(More)
OBJECTIVE AND DESIGN The fungicidal and bactericidal actions of the essential oil (EO) of Melaleuca alternifolia seem well established, but their anti-inflammatory and anti-oxidative effects remain unclear. In this study, we investigated in vitro the possible role of whole M. alternifolia EO as a modulator of the oxidative response, i.e. reactive oxygen(More)
VVA-B4 lectin was used to investigate the differences in Tn antigen expression in tissues of different types of human breast cancer (benign lesions, carcinoma in situ, invasive carcinoma) and in normal tissues neighboring lobular carcinoma. Locations in which Tn antigen was expressed were identified using the avidin-biotin-peroxidase labeling system.(More)
Choroid plexus papilloma may display unusual histologic features, but the presence of neuronal differentiation at the light microscopic level has not yet been described. We thus report a choroid plexus papilloma with neuropil-like islands located within the lateral ventricle of an 11-year-old girl. The absence of atypical histologic features associated with(More)
Between 1980 and 1985, 914 patients with head and neck squamous cell carcinoma underwent lymph node dissection in our institution. The prognostic value of clinical factors has already been reported (Mamelle et al, 1994, Am J Surg 168: 494-498). We present here a comparison of biological characteristics of pharyngeal tumours in patients who developed distant(More)
essential for two reasons. Firstly, patients with positive neck nodes have a higher risk of developing DM as have those with negative neck nodes (Leemans et al, 1993; Mamelle et al, 1994). Secondly, a heterogeneity between the tumour cell populations of the primary tumour site and the neck nodes is possible. Therefore an analysis of the distribution of(More)
