The adhesion of twenty nine Staphylococcus epidermidis strains to teflon, polyethylene, polycarbonate and bovine pericardium was studied in vitro and examined in relation to the surface free energies of both bacteria and biomaterials. All S. epidermidis strains had similar surface free energies, close to that of water, and adhered better to the materials(More)
In order to study the association of histological grade (HG) with specific clinical and biological parameters which may influence the clinical behavior of infiltrating ductal carcinomas of the breast (IDC), we analyzed in 229 tissue samples the cytosolic concentrations of estrogen receptor (ER), progesterone receptor (PR), pS2, cathepsin D, hyaluronic acid(More)
The proportion of carrier-isolated Neisseria meningitidis strains sensitive to human serum (37.2%) was found to be significantly higher than that of case-isolated ones (4.1%), although the difference is too low to consider serum-resistance responsible for invasion in this microorganism. Serum-susceptibility was not related to the existence of specific outer(More)
Pairwise correlations among surface charge, relative hydrophobicity and association with phagocytes were studied in two strains of Neisseria meningitidis both under normal conditions and after different surface modifying treatments. The variations in the values of the three variables depended on both strains and treatment, and correlations were highly(More)
INTRODUCTION There are several discrepancies in the literature concerning breast cancer behavior in elderly women. For this reason, we decided to study the possible clinical-biological differences between infiltrating ductal breast carcinomas in women older than 60 and those between 41 and 60 years old. PATIENTS AND METHODS The study group included 161(More)
BACKGROUND We aimed at studying the behavior of cytosol tissue-type plasminogen activator (t-PA) levels in lung adenocarcinomas and their correlation with other clinical and biological parameters. MATERIAL AND METHOD t-PA cytosol levels were determined using EIA (Boehringer Mannheim. Germany) in 59 samples of lung adenocarcinoma and in 16 samples of(More)
In order to investigate the possible hormone-dependence of CD44v6 in human breast cancer, we assayed the concentrations of this isoform in the membrane fraction of 168 invasive ductal carcinomas (IDC) and in 26 normal breast tissue samples, 18 fibradenomas (FAD), 3 fibrocystic disease specimens (FD), 7 mucinous carcinomas and 4 medullary carcinomas using(More)
To study the behavior and possible correlations of neuron-specific enolase (NSE) with other clinicobiological parameters, we measured the cytosolic levels of this marker by means of an immunoradiometric assay (IRMA) in 95 squamous cell lung carcinoma samples. We also analyzed the levels of pS2, tissue-type plasminogen activator (t-PA), hyaluronic acid (HA),(More)
