Abstract: A functionalized nanohydrogels have been synthesized by two step procedure. The first step implies an inverse microemulsion polymerization of p-nitro phenol acrylate (NPA) and N-isopropylacrylamide (NIPA) using Aerosol (AOT) as a surfactant and ethylene glycol dimethacrylate (EGDMA) as a crosslinking agent. The polymerization reaction was performed in presence of an oil-soluble salt to reduce the dimensions of the micellar diameter. The second step includes a chemical functionalization by nucleophilic substitution reaction over the carbonyl groups. The average particle diameter and the particle size distribution of the nanohydrogels were measured in acetone at 25°C by quasielastic light scattering (QLS) showing average diameter of 22 nm. The nanogels were characterized by FTIR-ATR, 1HNMR, UV-vis spectroscopy and DSC.

Antzelevitch, C.",,"2007",,"Background: Ventricular tachycardia (VT) and ventricular fibrillation (VF) complicating Brugada syndrome, a genetic disorder linked to SCN5A mutations, and VF complicating acute myocardial infarction (AMI) both have been linked to phase 2 reentry. Objective: Given the mechanistic similarities in arrhythmogenesis, the purpose of this study was to examine the contribution of SCN5A mutations to VT/VF complicating AMI. Methods: Nineteen consecutive patients developing VF during AMI were enrolled in the study. Wild-type (WT) and mutant SCN5A genes were coexpressed with SCN1B in TSA201 cells and studied using whole-cell patch clamp techniques. Results: Among the cohort of 19 patients, one missense mutation (G400A) in SCN5A was detected in a conserved region. An H558R polymorphism was detected on the same allele. Unlike the other 18 patients, who each developed 1-2 VF episodes during AMI, the mutation carrier developed six episodes of VT/VF within the first 12 hours. All VT/VF episodes were associated with ST-segment changes and were initiated by short-coupled extrasystoles. Flecainide and adenosine challenge performed to unmask Brugada and long QT syndromes both were negative. Peak G400A and G400A+H558R current were 70.7% and 88.4% less than WT current at -35 mV (P ?.001). G400A current decay was accelerated and steady-state inactivation was shifted -6.39 mV (V1/2 = -98.9 0.1 mV vs -92.5 0.1 mV, P ?.001). No mutations were detected in KCNH2, KCNQ1, KCNE1, or KCNE2 in the G400A patient. Conclusion: We describe the first sodium channel mutation to be associated with the development of an arrhythmic storm during acute ischemia. These findings suggest that a loss of function in SCN5A may predispose to ischemia-induced arrhythmic storm. 2 2007 Heart Rhythm Society.",,,,,,"10.1016/j.hrthm.2007.03.040",,,"http://hdl.handle.net/20.500.12104/43242","http://www.scopus.com/inward/record.url?eid=2-s2.0-34547408462&partnerID=40&md5=dbbd565b6f894ab56d84dbb50cc268fa",,,,,,"8",,"Heart Rhythm",,"1072

We carried out some optical simulations to show the feasibility to build up a multiplexer or de-multiplexer module for Dense Wavelength Division Multiplexing (4 channels). The set-up consists of a concave mirror that receives different beams which are then focused at the centre. For the case of a MUX-module, different radial positions enable injecting the system different wavelength inputs as the concave mirrors concentrates all the beams in one point (collector fibre). Moreover, for the case of a DEMUX-module, a bulk grating is positioned at one point between the concave mirror and the focal point of it, and when a stream of pulses with different wavelengths reaches this point, it automatically distributes the incoming signal in different radial positions (several collector fibers).
