Intellectual property rights and economic growth

2015

Striving for greater economic growth, requires a great understanding of the underlying factors. One of the factors may be the intellectual property rights and the level of its protection. Whether it is and how does it behave are the questions answered by this thesis. The theoretical framework comes mainly from the Schumpeterian growth model. The empirical methodology uses GMM in order to obtain reliable results. The level of intellectual property rights protection in the country does seem to have a positive effect on the country’s growth rate. Furthermore it seems that the relation is non-linear: The incremental changes are different between low and high starting levels of the IPR protectio…

Institutional Contexts, the Management of Patent Portfolios, and the Role of Public Policies Supporting New EntrepreneurialVentures

2009

This chapter aims to increase our understanding of the relationships between firm strategies, the design of institutional contexts on behalf of public agents, and the stimulation of diffused entrepreneurship within the economic system. In particular, it analyzes the way in which firm patent portfolio management strategies may systematically hinder the emergence of entrepreneurial endeavors within the economic system and, on this basis, critically discusses how the acknowledgement of these interactions should influence the design of public policies at the economic system level. We argue that in economic contexts where intellectual property rights (IPR) are influential, large firms may intent…

Transient hepatic nodular lesions associated with patent ductus venosus in preterm infants.

2010

We report on two cases of low-birth-weight preterm infants with patent ductus venosus associated with hepatic hypoechoic lesions of the fourth segment in an otherwise normal liver. Although tumorlike hepatic lesions have been previously reported in association with portosystemic shunts in children and adults, they were never described in preterm infants during physiological patency of ductus venosus. In our patients, hepatic lesions disappeared shortly after the spontaneous ductus closure. Physiopathologic interactions are discussed regarding altered portal blood supply caused by ductus venosus shunt.

Paradoxical embolism through a patent foramen ovale from central venous catheter thrombosis: A potential cause of stroke

2020

Paradoxical embolism refers to a potential condition in which an embolus arising from a venous source crosses into the systemic circulation through a right-to-left cardiac shunt causing an arterial embolism. A 39-year-old woman carrier of a central venous catheter (CVC) without evident risk factors for stroke, developed an acute right homonymous hemianopia during hemodialysis. On neuroimaging, an infarct in the territory of the left posterior cerebral artery was demonstrated. Transesophageal echocardiography revealed a patent foramen ovale (PFO) and a large fluctuating thrombus in the right atrium on the tip of the CVC, thus allowing a diagnosis of ischemic stroke from paradoxical embolism.…

Arterial O2-Partial Pressure at Positve Endexpiratory Pressure in Hyperoxia for Verification of Patent Foramen Ovale?

1990

As a rule, during anaesthesia a time dependent increase in pulmonary shunting occurs even in states of normal lung function. Therefore positive end-expiratory pressure ventilation (PEEP) is often used to decrease intrapulmonary right/left shunting (RL shunt) and thus to increase arterial O2 partial pressure (paO2) without increasing the inspiratory oxygen fraction.

Climate variability, innovation and firm performance: evidence from the European agricultural sector

2021

Abstract It is generally accepted that adaptation to climate variability requires a technological advancement strategy. However, the innovation process has received little explicit consideration in this framework. We employ a panel endogenous switching regression model to explore whether and to what extent climate variability affects firm performance through the ability to induce the development of adaptation innovations in key resource-based sectors in Europe during the period 2007–2017. Our findings confirm that the knowledge generation process at the heart of climate change adaptation technologies enhances firm performance, especially for firms in the aquaculture and fishing sub-sectors …

2017

Bikarfēna un ivabradīna kristālisko formu izpēte. Borisova A., zinātniskais vadītājs Dr. ķīm., prof. Andris Actiņš. Maģistra darbs, 60 lpp., 19 attēli, 7 tabulas, 46 literatūras avoti, 2 pielikumi. Latviešu valodā Darbs ir veltīts farmaceitisko vielu bikarfēna un ivabradīna kristālisko formu izpētei. Bikarfēna A formas paraugs tika pārkristalizēts no 25 šķīdinātājiem, ir iegūti 14 bikarfēna solvāti. Tika pārbaudīta solvātu stabilitāte paaugstinātā temperatūrā. Ivabradīna 10 kristālisko formu iegūšana bija veikta, pamatojoties uz pēdējo gadu patentos norādītām metodikām.

Percutaneous closure of left atrial appendage to prevent embolic events in high-risk patients with chronic atrial fibrillation

2009

Background: Percutaneous closure of the left atrial appendage (LAA) is a novel alternative for the treatment of patients with atrial fibrillation (AF) and with a high risk of stroke who are not eligible for long-term anticoagulation therapy. The aim of this study was to asses the safety, feasibility, and long-term efficacy of this procedure. Methods: From July 2004 to June 2007, 20 patients (13 male, mean age 69 ± 8 years) with non–valvular AF (NV-AF) underwent LAA percutaneous closure using the PLAATO™ system, implanted through a transeptal access. All patients had contraindications to anticoagulant therapy and were at high risk for cardioembolic stroke (mean CHADS2 score 3 ± 1.2). A trans…
