Erfahrungen mit einer 3D-Navigatorsequenz zur Koronargefäßdarstellung an einem Hochleistungs-MR-System
2002
Purpose: To evaluate MR coronary angiography using a three-dimensional navigator echo sequence on a MR scanner with a high performance gradient system. Material and Methods: Five healthy volunteers were examined with a 1.5 Tesla MR system, using a high performance prototype gradient system (peak amplitude 50 mT/m, rising time 600 μs). For imaging, a navigated gradient-echo pulse sequence with an in-plane resolution between 0.63 × 0.63 and 0.78 × 0.78 mm 2 was used. Per patient two overlapping slabs were acquired. The number of visualised coronary artery segments was estimated (AHA classification). In addition, signal-to-noise measurements were performed in the ascending aorta at the level o…
Quantitative Coronary Angiography and Digital Densitometric Perfusion Measurements?How to Assess the Success of Intracoronary Balloon Dilatation
1988
Densitometric evaluation of digital subtraction angiocardiograms allows the assessment of local myocardial perfusion before and after pharmacological stimulation of coronary flow reserve during the catheterization procedure. This report deals with a case of a severe stenosis of the left coronary artery in which PTCA was regarded successful based on an appropriate increase in luminal diameter while an intima and media dissection at the dilatation site was documented. The perfusion measurements, however, pointed out a clear impairment of poststenotic myocardial perfusion after PTCA.
Heart Failure: Really Idiopathic?
2016
Coronary angiography is necessary in the differential diagnosis of a newly discovered heart failure, which may be caused by multivessel disease and/or stenoses of major vessels. However, angiography is associated with a relatively high percentage of false negative findings in the assessment of left main disease. FFR allows unveiling these false negatives, even though special precautions need to be taken when stenoses are present also in the bifurcation branches.
Different effects of losartan and delapril on plasma PAI-1 levels in patients with mild to moderate hypertension
2003
ACE probably influences the fibrinolytic system at acentral point by converting angiotensin I to angiotensin II,which increases PAI-1 activity. This effect appears to bemediated via the AT1-receptor in humans. The RAAS mayalso contribute to a reduction in t-PA production by degra-dation of bradykinin, since the latter increases the release ofprostacyclin, nitric oxide, and t-PA from endothelial cells.Accordingly, ACE inhibitors not only influence the fibrino-lytic system by a reduction of PAI-1 activity but also byincreasing t-PA activity [1–3]. However, few studies haveanalysed the effects of AT1-R antagonists on t-PA and PAI-1plasma levels and the in vivo effects of AT1-R antagonistson th…
De Caperucita Roja a las slasher movies: reescrituras del cuento tradicional en la ficción cinematográfica norteamericana
2011
Desde los albores de la civilización, los relatos populares se han transmitido de generación en generación, conformando un tapiz tupido e interrelacionado que va desde la prehistoria de los indígenas norteamericanos y el Antiguo Testamento hasta nuestros días. A medida que los cuentos perviven al pasar de abuelos a nietos, estos desempeñan un papel determinante para la formación, la consolidación y la transmisión de los valores e ideales de la sociedad. Sin embargo, los avances tecnológicos y los profundos cambios que se producen en la sociedad estadounidense del siglo xx hacen que estas manifestaciones artísticas y culturales deban adaptarse a nuevos medios de transmisión. En el presente a…
The use made of video in the social media by candidates in the 2019 Valencian Autonomous Government elections
2020
Videos are increasingly being used in social networks for a wide range of purposes, including political campaigning. Here, social media seem to be gaining an edge over the mainstream variety when it comes to making political choices, especially during election campaigns. This paper examines the extent to which social media is used in Valencian Autonomous Government elections and looks at each of the candidate's experiences in this regard in the April 2019 elections. We pay particular attention to the differences between the three networks analysed — Facebook, Twitter and Instagram, and consider what kind of video information is shared. For these purposes, we create nine formal categories, s…
A Look at Valencia’s Elections of the 28th of April and the 26th of May 2019
2020
This paper analyses the main features of the Valencian media coverage of the elections held in Spain in the Spring of 2019 (General, Regional, Municipal, and European elections). We shine a spotlight on the key themes covered by the main newspapers, radio and TV stations, and on the campaign strategies parties used to define ideological blocs on the left and right.
Voting Transitions in the 2019 Valencian Autonomous Community’s Elections
2020
The political fragmentation following the 2008 Financial Crisis and its economic, social, political and institutional fall-out have led to a growing left-right polarisation of politics and a weakening of the middle ground. The effective number of parliamentary parties is at an all-time high both inthe Spanish Parliament (Congreso) and in the Valencian Autonomous Parliament (Corts). Voters are spoilt for choice and switch party more often. This paper uses transfer matrices to analyse the shifting voting patterns in the European, General, Regional, and Local elections held during 2019 in The Valencian Country. The most salient result is the ever-shifting pattern at each end of the political s…
Efficacy and safety study of an eyelid gel after repeated nocturnal application in healthy contact lens users and non-users
2020
Purpose: To evaluate skin biocompatibility of a nighttime hydrating eyelid gel and possible ocular surface effects in contact lens users (CLU) and non-contact lens users (NCLU). The formulation is registered as a medical device as Tridocosahexaenoine-AOX® (TDHA-AOX) (a concentrated DHA triglyceride), containing also hyaluronic acid (HA). Methods: A prospective, randomized, masked clinical trial was performed with 62 participants of both sexes, aged 20–70 years, split into: (1) CLU (n = 30) and (2) NCLU (n = 32). All participants were instructed to apply a single dose of the moisturizing gel (containing TDHA-AOX and HA) nightly to the upper and inner eyelids of their right eye (RE) only, and…
