Oxidative Stress and DNA Damage in Human Gastric Carcinoma: 8-Oxo-7'8-dihydro-2'-deoxyguanosine (8-oxo-dG) as a Possible Tumor Marker

2013

We characterized the oxidative stress (OS) status by the levels of reduced/oxidized glutathione (GSH/GSSG), malondialdehyde (MDA) and the mutagenic base 8-oxo-7′8-dihydro-2′-deoxyguanosine (8-oxo-dG) in human gastric carcinoma (HGC) samples and compared the results with normal tissue from the same patients. We also analyzed 8-oxo-dG in peripheral mononuclear cells (PMNC) and urine from healthy control subjects and in affected patients in the basal state and one, three, six, nine and twelve months after tumor resection. The levels of DNA repair enzyme mRNA expression (hOGG1, RAD51, MUYTH and MTH1) were determined in tumor specimens and compared with normal mucosa. Tumor specimens exhibited i…

Theoretical Basis Versus Clinical Practice of Oxygen Parameters of Blood

1996

Under optimal conditions all oxygen parameters of human blood are defined at a theoretical basis, accepted and understood by the clinicians, measured correctly by instruments of different manufacturers and, therefore, leading to clear diagnoses for the patients.

Interrelation of peptidergic innervation with mast cells and ED1-positive cells in rat thymus

1991

The peptidergic innervation of rat thymus has been investigated by immunohistochemical methods, focusing on the spatial interrelationship of peptidergic nerve fibers with mast cells and macrophages in the rat. An antiserum directed against the protein gene product 9.5 (PGP 9.5) regarded as a pan-neuronal marker revealed a rich innervation, especially in the subcapsular cortex, in interlobular septa, and of the vasculature in the cortex and the corticomedullary boundary. A minor proportion of PGP 9.5-immunoreactive (ir) fibers supplied the thymic parenchyma. The main component of peptidergic innervation consisted of fibers costaining for tachykinins (TKs) and calcitonin gene-related peptide …

Study of Cellular DIMA Content by Flow Cytometry in Primary Bladder Carcinomas

1992

A prospective study of cellular DNA content by flow cytometry was performed on a nonconsecutive series of 67 patients undergoing diagnostic and/or therapeutic transurethral resection for primary urothelial bladder carcinoma. DNA-aneuploidy was present in 82% of the cases (55/67), while multiclonality was found in 45% of the DNA-aneuploid cases (25/55). DNA-ploidy was much more strictly correlated with histological grading (p less than 0.005) than with papillary or non-papillary growth pattern (p less than 0.05) or T staging (p less than 0.05). Of 26 patients with a minimum follow-up of 24 months, 100% (6/6) of cases with DNA-diploid neoplasias showed no signs of disease relapse, versus 10% …

Klinische Relevanz der Anti-CEA-Immunszintigraphie mit dem99mTc-markierten monoklonalen Antikörper BW 431/26

1992

The results of 119 radioimmunoscintigraphies (RIS) in 113 patients with the 99mTc-labeled monoclonal anti-CEA-antibody BW 431/26 (Behring) have been analysed. The aim of our study was the estimation of the method's sensitivity and specificity under different aspects to find out for which indications and questions the 99mTc-RIS is useful. Colorectal primary tumours in 19 patients were scintigraphically detected with a sensitivity of 83% and a specificity of 100%; 3 out of 7 other tumour sites were localised correctly. 55 patients were examined during the follow-up of colorectal cancer. There were 17 out of 22 true positive findings of local recurrences (sensitivity 77%, specificity 88%). Liv…

Natalizumab therapy of multiple sclerosis: recommendations of the Multiple Sclerosis Study Group-Italian Neurological Society

2011

Three years after the introduction of natalizumab (NA) therapy for the second line treatment of relapsing-remitting multiple sclerosis (MS), Italian MS centers critically reviewed the scientific literature and their own clinical experience. Natalizumab was shown to be highly efficacious in the treatment of MS. However, the risk of progressive multifocal leukoencephalopathy was confirmed and defined better. This article summarizes the MS-SIN Study Group recommendations on the use of NA in MS, with particular reference to the appropriate selection and monitoring of patients as well as to the management of adverse events.

Rheological and metabolic leucocyte determinants in diabetes mellitus

1995

In diabetics of type I and 2 we examined, in resting white blood cells (WBC), the filtration parameters (Initial Relative Flow Rate - lRFR, Clogging Rate - CR) employing the St. George Filtrometer, the polymorphonuclear cells (PMN) membrane fluidity, the PMN cytosolic Ca2+ content and the PMN membrane cholesterol/phospholipid ratio (C/PL). From the obtained data, it is evident that, while the lRFR of unfractionated WBC distinguishes normals from diabetics of type 1 and 2, the fIltration parameters of the PMN and mononuclear cells (MN) do not show any significant difference. PMN membrane fluidity, PMN cytosolic Ca2+ content and PMN C/PL do not discriminate normals from diabetics of type 1 an…

Repeated courses of granulocyte colony-stimulating factor in amyotrophic lateral sclerosis: Clinical and biological results from a prospective multic…

2011

Granulocyte colony-stimulating factor (G-CSF) induces a transient mobilization of hematopoietic progenitor cells from bone marrow to peripheral blood. Our aim was to evaluate safety of repeated courses of G-CSF in patients with amyotrophic lateral sclerosis (ALS), assessing disease progression and changes in chemokine and cytokine levels in serum and cerebrospinal fluid (CSF). Twenty-four ALS patients entered an open-label, multicenter trial in which four courses of G-CSF and mannitol were administered at 3-month intervals. Levels of G-CSF were increased after treatment in the serum and CSF. Few and transitory adverse events were observed. No significant reduction of the mean monthly decrea…
