BACKGROUND/AIMS Migration of activated hepatic stellate cells (HSC) is a key event in the progression of liver fibrosis. Little is known about transmembrane proteins involved in HSC motility. Tetraspanins (TM4SF) have been implicated in cell development, differentiation, motility and tumor cell invasion. We evaluated the expression and function of four(More)
BACKGROUND To facilitate the clinical diagnosis of ventilator-associated pneumonia (VAP) in the ICU, the Clinical Pulmonary Infection Score (CPIS) has been proposed but has shown a low diagnostic performance in subsequent studies. We propose a new score based on procalcitonin level and chest echography with the aim of improving VAP diagnosis: the Chest(More)
Since 1989 recombinant human erythropoietin (rhEPO) has been used as a drug for the correction of anemia, but the misuse of rhEPO as an ergogenic agent among athletes is a widespread doping practice. As a consequence there is a need for developing reference methods for the detection of rhEPO in biological fluids, and to be able to differentiate the(More)
BACKGROUND Hemoglobin A1c (HbA1c) measurement is currently used for the routine monitoring of long-term glycemic status, thus playing a fundamental role in the management of this disease. Since this marker has recently been recommended as an additional tool for diagnosing diabetes, it's of the utmost importance to ensure that the precision and accuracy of(More)
Platelet activation has been suggested to play a crucial role in the pathogenesis of haemostatic disorders in antiphospholipid syndrome (APS). In 16 patients with primary APS (PAPS) we investigated by flow cytometry the presence of circulating activated platelets as defined by the surface expression of activation-dependent glycoproteins CD62 and CD63. In(More)
OBJECTIVES The aim of this study was to determine the reference values for serum cystatin C (CysC) with a particular focus on the effect of aging. DESIGN AND METHODS The study was performed on a consecutive series of subjects (258 men and 396 women). Laboratory parameters and a detailed personal and family medical history were collected. RESULTS CysC(More)
BACKGROUND DNA ploidy and S-phase fraction (SPF) measured by DNA flow cytometry (FC) have been previously shown to correlate with several clinicopathological variables in several types of tumours. PATIENTS AND METHODS DNA FC was performed on multiple frozen tumour samples obtained from 115 patients undergoing curative surgery for gastric cancer (GC). The(More)
Transferrin and ceruloplasmin have been measured by a solid-phase chemiluminescent method in seminal fluid and circulating blood of normal and vasectomized subjects (1 year after operation). This study has confirmed that approximately 80% of seminal transferrin comes from the testis, while seminal ceruloplasmin was not found different in the two groups. In(More)
The insulin-sensitising adipose hormone adiponectin is reduced in type 2 diabetic patients. We assessed the relationships between plasma adiponectin and chronic hyperglycaemia. Adiponectin levels and glycated haemoglobin (HbA1c) were measured at enrolment and after 90 days in 16 patients with type 2 diabetes aged (mean +/- SEM) 63.0 +/- 0.6 years, with body(More)
Telomerase is a ribonucleoprotein enzyme that adds TTAGGG repeats onto human telomeres, preventing their shortening. The activation of this enzyme is an important step in cell immortalization and carcinogenesis and seems to represent a new and promising marker in cancer diagnosis and management. Telomerase activity is usually detected in cellular protein(More)
