Recent evidence suggests that neutrophil gelatinase-associated lipocalin (NGAL) expression is induced in many types of human cancer, while detection of its complex with matrix metalloproteinase-9 (MMP-9) is correlated with cancer disease status. We aim to evaluate the serum expression of MMP-9, NGAL and their complex (MMP-9/NGAL) during the diagnostic(More)
This study examines pain (visual analog scale 0-10) in women undergoing breast biopsy. Two hundred and twenty-seven patients with a palpable lesion underwent FNA (21G, n=85), core biopsy (14G, n=86) or open biopsy under local anesthesia (n=56). One hundred and twenty-six women presented with a non-palpable lesion, and underwent vacuum-assisted breast biopsy(More)
PURPOSE The purpose is to investigate the prophylactic effect of intravesically instillated recombinant IFN-gamma against recurrence of superficial transitional cell carcinoma of the bladder and to evaluate its effect in local immune response, presumably mediating its therapeutic efficacy. EXPERIMENTAL DESIGN We prospectively randomized in two groups 123(More)
Pyruvate decarboxylase, isolated from active dry bakers’ yeast, dissociates into subunits of one-half the molecular weight at alkaline pH, This has been determined by chromatography on Sephadex G-200 over the pH range 6.5 to 8.0. The conditions at which protein dissociation is observed are the same as the conditions at which the cofactors thismine(More)
Thyroid disorders, including thyroid cancer and autoimmune thyroid diseases, have been closely associated with inflammation. This study aims to investigate the role of inflammation in thyroid disease by assessing serum cytokine levels in patients with malignant and benign thyroid conditions. Serum levels of ten interleukins (IL-1β, IL-2, IL-4, IL-5, IL-6,(More)
BACKGROUND The aim of this study was to investigate the effect of breast cancer adjuvant therapies on the levels of circulating surfactant protein-D (SP-D), C-Reactive protein (CRP) and soluble receptor for advanced glycation end-products (sRAGE), as potential biomarkers of subclinical pulmonary inflammation. MATERIALS AND METHODS The soluble molecules(More)
Breast and prostate constitute organs of intense steroidogenic activity. Clinical and epidemiologic data provide strong evidence on the influence of androgens and estrogens on the risk of typical hormone-dependent malignancies, like breast and prostate cancer. Recent studies have focused on the role of androgen metabolites in regulating androgen(More)
Deregulation of the endothelin system, comprised of endothelin-1 (ET-1), its isoforms (ET-2 and ET-3) and their receptors (ETAR and ETBR), is under investigation in various types of human cancer. ET-1 has been suggested to participate in breast cancer development and progression, while Big ET-1, its biological precursor, has also been found elevated in(More)
Pyruvate decarboxylase dissociates into sub-units of one half the molecular weight at alkaline pH. At the same conditions the cofactors thiamine pyrophosphate and Mg2+ are released and can be separated from the protein. Thiamine pyrophosphate is an obligatory cofactor for reconstitution to the oligomer [1]. In this study the effect of thiamine pyrophosphate(More)
Human plasma alpha-cysteine proteinase inhibitor (alpha CPI) was purified by a two-stage method: affinity chromatography on S-carboxymethyl-papain-Sepharose, and high-resolution anion-exchange chromatography. The protein was obtained as a form of Mr about 64 000 and material of higher Mr (about 100 000). In sodium dodecyl sulphate/polyacrylamide-gel(More)
