PURPOSE To compare short- and long-term clinical outcomes after conventional transarterial chemoembolization and drug-eluting bead (DEB) transarterial chemoembolization in hepatocellular carcinoma (HCC). MATERIALS AND METHODS Patients with unresectable HCC unsuitable for ablative therapies were randomly assigned to undergo conventional or DEB(More)
Directional modulation (DM) can be regarded as a new frontier in physical layer communication security. This new technique uses an antenna array as a spatial encryption system which partitions the surrounding space into regions where the transmission is either perfectly intelligible or intentionally obfuscated. Still, energy and spectral efficiencies of(More)
Specialist tutors have to transfer two types of knowledge to doctors who are specialising in a particular clinic: public declarative knowledge, including facts, notions, principles in that particular field; and their own private procedural knowledge acquired in years of direct experience. Embodying this knowledge into an expert system means that this(More)
Lung cancer is the commonest cause of cancer-related mortality throughout the world. Only 25% of patients are diagnosed early and are candidates for surgical resection with curative intent. Many early-stage patients are medically inoperable owing to comorbidities. For these patients, and for selected patients with pulmonary metastases, radiofrequency(More)
BACKGROUND The present study evaluated the predictive value of renal resistive index (RI) for renal function and blood pressure (BP) outcome in hypertensive patients with unilateral atherosclerotic renal artery stenosis submitted to successful revascularization. METHODS In 158 hypertensive patients with atherosclerotic renal artery stenosis RI was(More)
The GNSS operative monitoring equipment (GNOME) system is a distributed network of remote sentinels aimed at monitoring integrity, reliability and spoofing/interference-immunity of GNSS signals. The key features of this system directly come from the ICAO recommendations and standards which highly advise continuous control of the GNSS performance and(More)
Osteoid osteoma is a benign bone tumour; its main symptom is pain, which is sometimes resistant to analgesic or anti-inflammatory medication. The surgical treatment consists of en bloc excision or curettage of the lesion. Several alternative methods have been proposed, among which CT guided-percutaneous radiofrequency ablation. We report on ten patients who(More)
Endovascular stent-graft repair is emerging as the treatment of choice for complicated type B aortic dissection. In this report we describe a patient who presented with type B aortic dissection involving a right-sided aortic arch (RAA), a rare congenital vascular anomaly. The initial aggressive medical treatment proved unsuccessful due to false aneurysm(More)
