Bioeconomy credentials and intellectual capital: a comparative modelling approach for the E.U.-13 and E.U.-15

Acknowledging the importance of the bioeconomy as an important dimension of sustainable economic development, and particularly for E.U. strategies, this paper aims to identify and assess several bioeconomy modellers under the compelling effects of education and research–development–innovation activities. Within this frame of reference, the authors have assessed the role of intellectual capital in shaping bioeconomy outcomes, distinct for the new E.U.-13 and E.U.-15. A complex set of methods and macro-econometric models was applied on two balanced panels, compiled during 1995–2016, that bind random effects models with panel-corrected standard errors, spatial analysis and structural equation modelling. Overall, the importance of research, development, innovation and specific skills acquired in the field of bioeconomy is outlined, as key elements of E.U. economic strategies, being essential for all Member States

Mechanical thrombectomy techniques for acute ischemic stroke

Mechanical thrombectomy technique was introduced as an effective and secure method in acute ischemic stroke patients suffering from intracranial large vessel occlusion (LVO). In this article, we will review the main mechanical thrombectomy techniques and current trends in this type of treatment for acute ischemic stroke

Trends in the Evolution of the Average Length of Stay in Tourist Destinations on the Romanian Black Sea Coast

In recent decades, although most tourists have made several trips during a year, the average length of their vacations has decreased. The tendency to reduce the average length of stay of tourists has been evident in many destinations around the world in recent years. The purpose of this paper is to conduct an analysis of how the average length of stay of tourists in the main categories of destinations in Romania has evolved over the last decade, providing details about the evolution regarding tourist destinations located in the Romanian Black Sea coastal area. Starting from the possible causes identified in this paper, of the almost continuous decrease in the average length of stay in these destinations, we consider it necessary to undertake more in-depth studies, to find out the causes of these developments, which will be the basis of future development and marketing strategies regarding the respective tourist resorts

Temporo-sylvian anastomosis and aneurysm clipping in a case of left M1 aneurysm with progressive evolution after initial embolization: Case report

A giant unrupted middle cerebral artery aneurysm partially thrombosed, previously endovascularly treated after a mild right hemiparesis remitted. After 12 months, in routine check we discovered a reperfusion of the aneurysm and decide EC-IC bypass and clipping, with a good outcome

Preliminary study of thrombogenicity induced by the nanoparticle surface coating of intracranial stents

Endovascular treatment of intracranial aneurysms with intracranial stents was proven to be clinically safe and effective, but is still associated with a risk of thromboembolic complications. Stent thrombosis could be a sever complication associated with specific stent surface coatings and designs. Standardized in vitro tests for investigation of thrombogenicity induced by different nanomaterials were used as the basic method in carrying out the present study. Therefore, the aim of this study was to evaluate the thrombogenicity of three different nanomaterials (ZnO, TiO2 si Fe3O4) possible used as surface coating for intracranial stents. This study is based on a procedure for in vitro analyses of plasma coagulation time. To measure the plasma coagulation time, platelet-poor plasma from human whole blood was in vitro exposed to nanoparticles and analysed in prothrombin (PT) and activated partial thromboplastin (APTT)

Current applications of 3d printing in neurosurgery

Medical implications of 3-dimensional (3D) printing technology have progressed with increasingly used especially in surgical fields. 3D printing techniques are practical and anatomically accurate methods of producing patient specific models for medical education, surgical planning, training and simulation, and implants production for the assessment and treatment of neurosurgical diseases. This article presents the main directions of 3D printing models application in neurosurgery

Associated intracranial lesions: meningioma and anterior communicating aneurysm

Asymptomatic associated intracranial lesions are more frequently diagnosed with the utilization of high-resolution imaging. The occurrence of brain tumors together with intracranial aneurysms are a very rare situation. This coexistence is still a diagnostic and therapeutic challenge as no consensus concerning imaging that may cover both type of intracranial lesion was established. We report a case of a 62 years old patient with a meningioma and aneurysm treated in one session with good outcome

Management of spinal dural arteriovenouse fistula

Spinal dural arteriovenous fistulas are rare vascular lesions whose management is still at high interest between specialists. If microsurgical treatment is still considered as treatment of choice for SDAVFs, endovascular treatment is increasingly grow in interest with the development of endovascular techniques and new embolization materials. In this article we made a short discussion about the spinal dural arteriovenous fistulae on aspects related to anatomy, pathophysiology, diagnosis and treatment, with some general conclusions
