Aim: The aim of this study was to compare contrast-enhanced ultrasonography (CEUS) to baseline US and contrast-enhanced computed tomography (CT) in metastatic disease of the liver diagnosed or suspected by US during presurgical staging or postsurgical follow-up for primary malignancies. Materials and methods: Two hundred-fifty-three patients considered(More)
OBJECTIVE The objective of our study was to compare diagnostic performance of visual and quantitative analysis for the characterization of liver tumors insonated at low transmit power after microbubble contrast agent injection. SUBJECTS AND METHODS This series comprised 166 liver tumors (1-5 cm in diameter) in 166 patients (99 men, 67 women; mean age +/-(More)
The antibody-mediated delivery of therapeutic agents to sites of angiogenesis is an attractive strategy for anticancer therapy, but is largely unexplored in hematologic malignancies. In the present study, we show that the extra domain B (EDB) of fibronectin, a marker of angiogenesis, is expressed in B-cell non-Hodgkin lymphoma (NHL) and that the human(More)
We describe a new method for producing homogeneous eukaryotic N-glycoproteins. The method involves the engineering and functional transfer of the Campylobacter jejuni glycosylation machinery in Escherichia coli to express glycosylated proteins with the key GlcNAc-Asn linkage. The bacterial glycans were then trimmed and remodeled in vitro by enzymatic(More)
The aim of this study was to assess the feasibility of contrast-enhanced ultrasound (US) at low transmission power insonation for diagnosis of focal renal perfusion defects (RPDs) in rabbits. In seven adult New Zealand White rabbits focal RPDs were induced by polyvinyl alcohol embolizing particles (150–250 μm in diameter) injected into the abdominal aorta.(More)
The isolation of mammalian cell lines capable of high-yield expression of recombinant antibodies is typically performed by screening multiple individual clones by limiting dilution techniques. A number of experimental strategies have recently been devised to identify high-expressing clones, but protocols are often difficult to implement, time consuming,(More)
Postprandial hyperglycemia and glycemic oscillations have been associated with increased oxidative stress. We sought to investigate the effect of two walking exercise protocols performed during lunchtime on glycemic control and oxidative stress in type 2 diabetic (T2D) patients. Nine T2D patients participated in three randomized crossover trials; a control(More)
BACKGROUND Celiac disease is considered to arise from an inappropriate T-cell-mediated immune response against ingested gluten in genetically predisposed people, whereas the T(H)2-type lymphocytes are mostly involved in IgE-mediated reactions. The matter of possible coexistence of T(H)1- and T(H)2-type diseases is still debated. OBJECTIVE This study was(More)
INTRODUCTION Untreated coeliac disease may induce malabsorption of many nutrients. It may also induce vitamin K deficiency, which causes prolongation of the prothrombin time. The aim of the present study was to evaluate the prevalence and associations of prolonged prothrombin time in a series of coeliac adults. METHODS We carried out a cross-sectional(More)
Synthesis of three new cationic thiol-reactive maleimide-porphyrin derivatives and their use in site-specific conjugation to monoclonal antibodies is reported. The selective reactivity toward thiols is demonstrated using competition experiments, where both thiols and amines are present. This selectivity was used to successfully achieve specific conjugation(More)
