High-frequency rotational ablation following failed percutaneous transluminal coronary angioplasty.
1994
Percutaneous transluminal coronary angioplasty (PTCA) failed in 29 of 1,150 patients (2.5%) after successful passage of the guide wire. The reasons for failure were inability to pass the lesion with a balloon in 28 patients and inability to dilate the lesion in 1 patient. In these patients (15 stenoses and 14 chronic occlusions) rotational ablation was performed. We were able to pass the burr through the lesion in all of them, resulting in a reduction of diameter stenosis from 87 +/- 15 to 51 +/- 18%. Rotational ablation alone was initially successful (stenoses reduction > 20% and residual stenoses < 50%) in 15 of 29 (52%) patients. Additional PTCA was performed in 21 of 29 (72%) patients, …
Imaging in the catheterization laboratory
1993
Recent work confirms that visual assessment of the effect of widely employed coronary interventions is highly inaccurate. Rapid and reliable on-line angiographic quantitation is a useful advance, but problems in the application of the technique are encountered in a substantial number of cases. New algorithms have been devised to provide a comprehensive assessment of the geometry and likely functional significance of lesions as well as an objective evaluation of lesion morphology, and recent work has provided the framework for the quantitation of diffuse disease. Studies with intravascular ultrasound confirm the inadequate sensitivity of angiography in demonstrating mild to moderate atheroma…
P11.09 Pan-RTK inhibition of sLRIG1 mediates AXL downregulation in Glioblastoma
2019
Abstract INTRODUCTION Aberrant regulation of receptor tyrosine kinase (RTK) activity is characteristic of Glioblastoma (GBM). However, RTK-based targeted therapies have been largely unsuccessful in GBM patients, partially due to the complexity and redundance of RTK signaling. LRIG1 (Leucine-rich Repeats and ImmunoGlobulindomains protein 1) is known as an endogenous inhibitor of epidermal growth factor receptor (EGFR) during health and disease, however its mechanism of action is poorly understood. We previously showed that the soluble form of LRIG1 potently inhibits of GBM growth in vivo, irrespective of EGFR expression level and status, suggesting the involvement of other RTKs. Here, we aim…
Recanalization of Totally Occluded Coronary Vessels by Percutaneous Transluminal Coronary Angioplasty
1986
Since its introduction in 1977, percutaneous transluminal coronary angioplasty (PTCA) has become an effective approach for treatment of patients with single-vessel disease [1–3, 5]. Treatment of double- and multiple-vessel disease has also been attempted [5, 6]. In patients with angina pectoris total occlusion of coronary vessels is found, and PTCA has also been used in an attempt to restore coronary blood flow in such patients [8, 10]. Even main stem occlusions have been recanalized [11]. In patients with total occlusion of coronary vessels, collateral flow is sufficient to maintain cardiac function at rest but not during exercise [12–14]. Therefore, PTCA seems to be an ideal method for re…
Carotid and peripheral atherosclerosis in patients who underwent primary percutaneous coronary intervention and outcome associated with multifocal at…
2006
AIM: The aim of our study was to determine if patients with multifocal atherosclerosis have a worse prognosis than patients with atherosclerosis only in the coronary bed. METHODS: We studied 45 subjects admitted to intensive coronary care unit of the Division of Cardiology with the diagnosis of acute myocardial infarction (AMI). Traditional cardiovascular risk factors were investigated and laboratory analysis included measurement of plasma lipids, glycemia, fibrinogen and high-sensitivity-C-reactive protein (hs-CRP). Each patient underwent coronary-angiography as well as carotid and peripheral arterial ultrasound examination. A follow-up of 13+/-2 months was performed. RESULTS: We found tha…
Changes in Cement Paste and Mortar Fluidity after mixing induced by PCP: A parametric study
2006
International audience; The interaction mechanism between polycarboxylate-type superplasticizer (PCP) and cement hydration is not fully understood and incompatibilities between concrete and additive are sometimes observed. In some cases, the fluidity tends to increase (“overfluidification”) few minutes after mixing. This is a problem because the overfluidification leds to bleeding of the concrete which could be critical on job site. Our study consisted first in highlighting the phenomenon of “over-fluidification” by slump flow tests on mortar. Next, the time evolution of the rheological behaviour of cement pastes in the presence of PCP was analysed thanks to a rheometry protocol in order to…
TRANSACTIONAL SEX, EARLY MARRIAGE, AND PARENT– CHILD RELATIONS IN A TANZANIAN SLUM
2016
Transactional sex has been recognized as a major factor in the persistence of HIV/AIDS in Sub-Saharan Africa, yet it also has implications for the persistence of poverty. Using interview data collected between 2010 and 2015, this article examines how Muslim families in Dar es Salaam are affected by transactional sexual behavior.1 Examined are motives for transactional sex, how poor families view the purpose of marriage, and religious teachings and cultural beliefs about the onset of adulthood. Familial strategies to ensure provision for daughters and to improve the family’s socio-economic situation are impeded by the fact that in a context of high unemploy ment, transactional sex of ten rep…
Tourism in the Days of Morbid Consumption
2019
This chapter centers on the changes, limitations and future challenges tourism research faces in the years to come. In the days of morbid consumption, which means the proliferation of new dark forms of consumption as dark tourism, slum tourism, last day tourism or even war-tourism, scholars seem to be misguided or trapped into conceptual gridlocks. In fact, our grandparents chose other types of destinations for their holidays. Instead, new forms of tourism—more oriented to spaces of destruction, mass death and suffering—are surfacing. This chapter, echoing the main contributions of Dean MacCannell, calls for the introduction of ethics in business. This begs the following question: to what e…
Tourism in the European economic crisis: Mediatised worldmaking and new tourist imaginaries in Greece
2016
The article interrogates the rationale and origins of changing imaginaries of tourism in Greece in the context of the current economic crisis. We detect a radical change in the ‘picture’ of the country that circulates in global media conduits (YouTube, Facebook, official press websites and personal blogs). We enact a journey into past media representations of Greece as an idyllic peasant and working-class site, but proceed to highlight that such representations are being recycled today by Greeks (especially but not exclusively) living and studying abroad. This stereotype, which focuses on embodied understandings of happiness and well-being, is being challenged by the current economic crisi…
