Septal rupture with right ventricular wall dissection after myocardial infarction
Carlos J Soriano, José L Pérez-Boscá, Sergio Canovas, Francisco Ridocci, Pau Federico, Ildefonso Echanove, Rafael Paya
Cardiovascular Ultrasound , 2005, DOI: 10.1186/1476-7120-3-33
Abstract: We present a case of a 59-year-old man who had a septal rupture with right ventricular wall dissection after inferior and right ventricular myocardial infarction. Transthoracic echocardiography, as first line examination, established the diagnosis, and prompt surgical repair allowed long-term survival in our patient.Outcomes after right ventricular intramyocardial dissection following septal rupture related to myocardial infarction has been reported to be dismal. Early recognition of this complication using transthoracic echocardiography at patient bedside, and prompt surgical repair are the main factors to achieve long-term survival in these patients.The occurrence of ventricular septal rupture after acute myocardial infarction is an uncommon complication in the reperfusion era [1], however, this condition implies a high mortality rate, even after surgical repair [2]. In patients with inferior myocardial infarction, septal rupture generally involves basal inferoposterior septum, and the communicating tract between left and right ventricle is often serpiginous with a variable degree of right ventricular wall extension [3]. Right ventricular wall dissection following septal rupture related to previous myocardial infarction has been reported in a very few cases [4-6], in many of them this condition has been diagnosed in post-mortem studies [4]. In a recent report long-term survival has been achieved after promptly echocardiographic diagnosis and surgical repair [6].A 59-year-old man was admitted to Coronary Care Unit because of suspected ST-segment-elevation myocardial infarction. The patient was complaining of typical coronary chest pain during the last twelve hours. He had a history of dyslipidemia, type 2 diabetes mellitus, smoking habit and a transient ischemic attack without any sensitive or motor squele one year ago. On admission, his blood pressure was 100/60 and heart rate was 110 beats per minute. Cardiac examination revealed jugular vein distension, and no s
Mitochondrial DAMPs Induce Endotoxin Tolerance in Human Monocytes: An Observation in Patients with Myocardial Infarction

Abstract: Monocyte exposure to mitochondrial Danger Associated Molecular Patterns (DAMPs), including mitochondrial DNA (mtDNA), induces a transient state in which these cells are refractory to further endotoxin stimulation. In this context, IRAK-M up-regulation and impaired p65 activity were observed. This phenomenon, termed endotoxin tolerance (ET), is characterized by decreased production of cytokines in response to the pro-inflammatory stimulus. We also show that monocytes isolated from patients with myocardial infarction (MI) exhibited high levels of circulating mtDNA, which correlated with ET status. Moreover, a significant incidence of infection was observed in those patients with a strong tolerant phenotype. The present data extend our current understanding of the implications of endotoxin tolerance. Furthermore, our data suggest that the levels of mitochondrial antigens in plasma, such as plasma mtDNA, should be useful as a marker of increased risk of susceptibility to nosocomial infections in MI and in other pathologies involving tissue damage.
A rational expectations model for simulation and policy evaluation of the Spanish economy
J. E. Boscá,A. Díaz,R. Doménech,J. Ferri,E. Pérez,L. Puch
SERIEs , 2010, DOI: 10.1007/s13209-009-0013-8
Abstract: This paper presents the model used for simulation purposes within the Spanish Ministry of Economic Affairs and Finance. REMS (a Rational Expectations Model for the Spanish economy) is a small open economy dynamic general equilibrium model in the vein of the New-Neoclassical-Keynesian synthesis models, with a strongly micro-founded system of equations. In the long run REMS behaves in accordance with the neoclassical growth model. In the short run, it incorporates nominal, real and financial frictions. Real frictions include adjustment costs in consumption (via habits in consumption and rule-of-thumb households) and investment into physical capital. Due to financial frictions, there is no perfect arbitrage between different types of assets. The model also allows for slow adjustment in wages and price rigidities, which are specified through a Calvo-type Phillips curve. All these modelling choices are fairly in line with other existing models for the Spanish economy. One valuable contribution of REMS to the renewed vintage of D(S)GE models attempting to feature the Spanish economy is the specification of the labour market according to the search paradigm, which is best suited to assess the impact of welfare policies on both the intensive and extensive margins of employment. The model’s most valuable asset is the rigour of the analysis of the transmission channels linking policy action with economic outcomes.
Copper and Cyanide Recovery in Cyanidation Effluents  [PDF]
José R. Parga, Jesús L. Valenzuela, Héctor Moreno, Jaime E. Pérez
Advances in Chemical Engineering and Science (ACES) , 2011, DOI: 10.4236/aces.2011.14028
Abstract: Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as the precipitator, and sulfuric acid for pH control. Results show that pH value has a significant effect on copper cyanide removal efficiency, and it was determined the optimal pH range to be 2.5 - 3. At this pH value, the copper cyanide removal efficiency achieved was up to 97 and 99%, when copper concentration in the influent was 636 and 900 ppm. respectively. In this process (sulphidization-acidification-thickening-HCN recycling), the cyanide associated with copper cyanide complexes, is released as HCN gas under weakly acidic conditions, allowing it to be recycled back to the cyanidation process as free cyanide. Cyanide recovery was 90%. Finally, this procedure was successfully run at Minera William in México.
La información de Internet como se?al de video y su editor

Signo y Pensamiento , 2010,
Abstract: based on some authors' analyses of the terms video, virtual, and real, and the ways in which they converge in visual productions on the web, we examine what in actual fact constitutes a video in that space; internet is considered a source of information which, in many cases, is visualized as video. it is assumed that such information presents many variables that, in the end, define the way in which it is to be presented; there are variables which can not be precisely assessed, thus turning the unpredictable factors into an actual editor of the information shown on internet via a video signal.
