OBJECTIVE We evaluated the biological properties of High-grade prostatic intraepithelial neoplasia (PIN) by immunohistochemistry and fluorescence in situ hybridization (FISH) analysis in relation to normal tissue and carcinoma lesions. MATERIALS AND METHODS Immunohistochemical staining and FISH were performed on 23 formalin-fixed radical prostatectomy specimens taken from patients with PIN. A...

Interest in translational studies aimed at investigating the role of biologic markers in predicting clinical outcome of breast cancer patients and, in particular, response to specific treatments, has progressively increased. Among biologic variables presently under investigation, apoptosis markers, in particular Bcl-2 and Bax expression, are receiving much attention for their relationship with ...

BACKGROUND Galectin-3 (Gal-3) has been suggested as a prognostic biomarker in heart failure (HF) patients that may better reflect disease progression than traditional markers, including B-type natriuretic peptide (BNP) and cardiac troponins. To fully establish the utility of any biomarker in HF, its biologic variability must be characterized. METHODS To assess biologic variability, 59 patient...

Background: Biologic drugs, especially anti TNF-α are revolutionary in the treatment of Spondyloarthritis when conventional DMARDs have proved ineffective. Research objective: To evaluate effectiveness Infliximab on patients. Materials and method: Longitudinal follow-up study with 27 patients Spondyloarthritis. Results: The is demonstrated by clinical indicators; inflammatory markers: CRP, ESR ...

This paper deals with the area of environmental epidemiology involving measurement of exposure and dose, health outcomes, and important confounding and modifying variables (including genotype and psychosocial factors). Using examples, we illustrate strategies for increasing the accuracy of exposure and dose measurement that include dosimetry algorithms, pharmacokinetic models, biologic markers,...

We evaluated HBME1, galectin-3 (GAL3), cytokeratin (CK)19, and a new anti-CITED1 antibody in 127 follicular adenoma (FA) and papillary thyroid carcinoma (PTC) cases. The findings were used to evaluate 11 diagnostically challenging encapsulated follicular lesions with questionable features of PTC (FL/QPTC). All 4 markers showed higher expression in PTC than FA. HBME1 was the most specific (96%),...

BACKGROUND Takayasu arteritis (TAK) is a large vessel vasculitis that rarely affects children. Data on childhood TAK are scarce. The aim of this study was to analyze the presenting features, course and outcome of children with TAK, compare efficacy of treatment regimens and identify high-risk factors for adverse outcome. METHODS A single-center cohort study of consecutive children fulfilling ...

Cancer chemoprevention is defined as the use of natural, synthetic, or biologic chemical agents to reverse, suppress, or prevent carcinogenic progression to invasive cancer. The success of several recent clinical trials in preventing cancer in high-risk populations suggests that chemoprevention is a rational and appealing strategy. This review will highlight current clinical research in chemopr...
