Use of Anesthetics Associated to Vasoconstrictors for Dentistry in Patients With Cardiopathies. Review of the Literature Published in the Last Decade
2012
Objective: The use of local anesthetics associated to vasoconstrictor agents in dentistry is thoroughly justified and is widely extended, but we cannot ignore the fact that anesthetic infiltration poses risk of complications throughout the dental treatment period. The objective of the present review is to document the reported effects the use of the local anesthetics most widely employed in dentistry, with or without association to vasoconstrictor agents may have in patients with any sort of cardiopathy. Study Design: We have searched for randomized clinical trials on the assessment of the cardiovascular effects of local anesthetics used in dentistry, without limits as regards age or sex, c…
Dislocated Temporalities : Immigration, Identity, and Sexuality in Najat El Hachmi?s «L?últim patriarca»
2018
Recent Catalan criticism has focused on place and space, as well as immigration, but has overlooked temporality. Yet migrations are not only a matter of space (of demographic movements and geographical relocations), but also of time: immigration questions the idea of origins and the possibility of a shared future, and problematizes the rhythms of everyday life. Temporality, in fact, is a key axis in the formation of identities and in cultural conflicts, not just regarding the uses of the past and the projection of societies towards the future, but also in relation to the normative uses of the body. The coexistence of asynchronous temporalities provoked by immigration is a factor in both cul…
QT Indexes in Cirrhotic Patients: Relationship with Clinical Variables and Potential Diagnostic Predictive Value.
2015
Background and Aims A wide spectrum of cardiovascular changes characterizes cirrhosis, ranging from subclinical alterations to hyperkinetic syndrome. We looked for ECG markers of ventricular repolarization in a population of patients with cirrhosis in comparison to patients without cirrhosis and we investigated the relationship between these and other clinical and laboratory variables. Methods In 149 patients with cirrhosis and 152 controls, we measured QT maximum interval (QTmax), QT corrected interval (QTc), QT minimum interval (QTmin), QT dispersion (QTdisp), QT peak and T peak-to-end (TpTe). Results In subjects with cirrhosis, in comparison with controls, we observed a higher mean QTmax…
The oxidation state of iron in silicic melt at 500 MPa water pressure
2002
Abstract The dependence of the ferric–ferrous ratio in silicate melts on oxygen fugacity was studied in the system SiO2(Qz)–NaAlSi3O8(Ab)–CaAl2Si2O8(An)–H2O using Mossbauer spectroscopy. Experiments were performed under water-saturated conditions at 500 MPa, and at temperatures of 850 and 950 °C, covering a range typical for magmatic processes. The oxygen fugacity was varied in the fO2 range from Cu–Cu2O buffer to slightly more reducing conditions than the wustite–magnetite buffer. The iron redox ratio was determined by analyzing the Mossbauer parameter distribution that was modeled based on experimental spectra collected at room temperature on the quenched samples. The obtained iron redox …
Digital signal processing for relaxation data conversion
2005
Abstract The origins, philosophy and basic practical aspects are considered for an approach of digital data transformations for broadband dielectric relaxation spectroscopy and other relaxation experiments carrying out direct and inverse integral transforms with kernels depending on the ratio or product of arguments. The approach is based on the concept that the mentioned data transformations represent a filtering problem on a logarithmic scale allowing one to implement the transforms by digital functional filters with the logarithmic sampling. As an example, digital Kramers–Kronig transformers are considered.
Multipore membranes with nanofluidic diodes allowing multifunctional rectification and logical responses
2016
[EN] We have arranged two multipore membranes with conical nanopores in a three-compartment electrochemical cell. The membranes act as tunable nanofluidic diodes whose functionality is entirely based on the pH-reversed ion current rectification and does not require specific surface functionalizations. This electrochemical arrangement can display different electrical behaviors (quasi-linear ohmic response and inward/outward rectifications) as a function of the electrolyte concentration in the external solutions and the applied voltage at the pore tips. The multifunctional response permits to implement different logical responses including NOR and INHIBIT functions.

Chi è il nemico?
2019
Attraverso una critica della tesi di Schmitt sul comandamento evangelico dell’amore per il nemico – si darebbe un tipo di nemico che ne va escluso – si cerca di mostrare come l’amore evangelico riguardi inequivocabilmente il caso della separazione e opposizione «estrema» – operi, per così dire, nello «stato d’eccezione» – e restituisca innanzitutto nel suo significato più radicale il concetto di nemico Through a critique of Schmitt's thesis on the evangelical commandment of love for the enemy – an excluded type of enemy would be given – an attempt is made to show how evangelical love unequivocally concerns the case of "extreme" separation and opposition – operate, so to speak, in the "state…
ST segment elevations: Always a marker of acute myocardial infarction?
2013
AbstractChest pain is one of the chief presenting complaints among patients attending Emergency department. The diagnosis of acute myocardial infarction may be a challenge. Various tools such as anamnesis, blood sample (with evaluation of markers of myocardial necrosis), ultrasound techniques and coronary computed tomography could be useful. However, the interpretation of electrocardiograms of these patients may be a real concern. The earliest manifestations of myocardial ischemia typically interest T waves and ST segment. Despite the high sensitivity, ST segment deviation has however poor specificity since it may be observed in many other cardiac and non-cardiac conditions. Therefore, when…
