this paper using endogenous growth models based on research and development, has investigated two economic relations in three groups of countries included developed countries, developing countries and a mixed group of both mentioned ones. at first, the effects of r&d; activities on patent growth have examined and then the relation between volume of patent and growth rate in these groups has sur...
This case report was an attempt to present the importance of diagnostic echocardiography and closure of a patent foramen ovale in carcinoid heart disease. Herein, we present a case of a 48-year-old woman with a carcinoid metastasis presenting with tricuspid regurgitation, pulmonic stenosis, patent foramen ovale, and borderline left ventricular ejection fraction on an echocardiogram. Surgical in...
Creating legal incentive institutions is one of the grounds necessary for scientific and economic growth. By creating financial incentives for inventing, the patent system increases competition and encourages technological and as a result, economic growth. Considering it leads intellectual and financial investments into new knowledge and technology and leads to of the R&D sector, promotion of c...
PURPOSE We examined the presentation, diagnosis and management of radiologically detected pediatric urachal anomalies and assessed the risk of malignant degeneration. MATERIALS AND METHODS Our radiology database (2000 to 2012) was queried for all children younger than 18 years who were diagnosed with a urachal anomaly radiographically, and the operative database was used to determine those wh...

In this work, we present the first comprehensive molecular field analysis of patent structures on how the chemical structure of drugs impacts the biological binding. This task was formulated as searching for drug structures to reveal shared effects of substitutions across a common scaffold and the chemical features that may be responsible. We used the SureChEMBL patent database, which prov...
In this research, protection of commercial expectation has been examined. The main question is how we could identify and assess existence of commercial expectations. In response, commercial expectation are acquisition of expectable benefit in market, mass production, absence of technical failure in licensed knowledge and so on.

BACKGROUND The embryological and anatomical features of urachal anomalies have been well defined. Because of the variable clinical presentations, uniform guidelines for evaluation and treatment are lacking. In an attempt to establish an optimal diagnostic and treatment modality, we report our experience with urachal anomalies at a single institution over a 10-year period. METHODS The records ...
