Nanotechnology research has experienced rapid growth in recent years. Advances in information technology enable efficient investigation of publications, their contents, and relationships for large sets of nanotechnology-related documents in order to assess the status of the field. This paper presents the development of a new knowledge mapping system, called Nano Mapper (http://nanomapper.eller....

The predictive accuracy of exercise thallium-201 (201Tl) myocardial scintigraphy in the evaluation of aortocoronary bypass graft surgery was assessed in 48 patients undergoing angiographic investigation 15 months (mean time) after myocardial revascularisation. 201Tl scintigrams detected 61 out of 77 (79%) patent grafts but only 21 out of 42 (50%) occluded grafts, though, for grafts supplying no...

BACKGROUND Sclerotherapy with polidocanol microfoam injection under duplex guidance is a new treatment for venous malformations associated with Klippel-Trenaunay syndrome. Multidetector-row computed tomography (MDCT) venography is extremely helpful in the assessment of disease extension and the planning of therapy. Observation In this particular case, MDCT venography demonstrated the origin, co...

The aim of the present study was to determine if patients with both pulmonary arterial hypertension (PAH), due to pulmonary vascular obstructive disease, and congenital heart defects (CHD), have mutations in the gene encoding bone morphogenetic protein receptor (BMPR)-2. The BMPR2 gene was screened in two cohorts: 40 adults and 66 children with PAH/CHD. CHDs were patent ductus arteriosus, atria...

Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...

Among the research on patents, the applications of Patent Map to Patent Analysis have been gradually emphasized. For three years, the researchers have applied Patent Map Theory Model to establishing Patent Map System (PMS) assisting decision-makers in Patent Analysis. Based on the system requirements, relevant function components are planned, and UML technology is utilized for the design and es...

the patents’ term prolongation through protecting the new detected uses is the problematic matter that has been seriously attended by the developed countries in recent years. iranian legislators’ uncertainty toward the subject within the respective legislatures illustrates the legal importance of taking a stance, which is consistent with the primary principles of patent law and international ob...
