Conclusions: It is feasible to use the wall between the aorta and left atrium as an access route for a potentially entirely percutaneous LVAD. Such a system obviates the need for accessing the left ventricle, minimizing complications. In the future, such devices may allow widespread treatment of heart failure, malignant cardiac arrhythmia, and severe aortic and mitral valvular disease. (J Cardiac Fail 2011;17:511-518)”
“Salvia species have been mainly studied for essential oils; among them Salvia tomentosa Mill. has been commonly used for various activities. Finding novel formulations for application of essential oils has
been a concern of the field. In this study, organogels of essential oil of Salvia tomentosa have been investigated LY2603618 concentration with a novel preparation method. The uniformity, antibacterial, antifungal activity and antioxidant properties of Salvia tomentosa essential oil and its organogel formulation were evaluated. According to the results, it can be stated that formulation in C974 organogels was successfully prepared very fast with PEG 400 under microwave irradiation. The NMR and GC/MS studies confirmed the unchanged structure of essential oil. TEAC and antimicrobial activity studies Trk receptor inhibitor showed the efficiency in the organogels. Formulation prepared can be used for antimicrobial and antioxidant purposes in topical drug delivery. The suggested method is suitable for scale-up and a process like that should be time and energy
saving.”
“We report on the fabrication and tunneling characteristics of pulsed-laser deposited LaSrMnO (LSMO)/PbZrTiO(PZT)/LSMO/SrTiO(3) multilayers, using PZT layer as a tunnel barrier. The trilayer films show magnetic onset at about 360 K with ferromagnetic hysteresis at room temperature. The microscopic studies show that the effective barrier thickness is reduced due to the presence of defects in the barrier region. this website Our results suggest that the asymmetric
deformation of the barrier potential profile induced by the ferroelectric polarization of PZT influences the tunneling characteristics and can be used for electrically controlled readout in quantum-computing schemes. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3054380]“
“Background: Studies have shown that the autonomic dysfunction accompanied by impaired baroreflex sensitivity was associated with higher mortality. However, the influence of decreased baroreflex sensitivity on cardiac function, especially in diastolic function, is not well understood. This study evaluated the morpho-functional changes associated with baroreflex impairment induced by chronic sinoaortic denervation (SAD).
Methods and Results: Animals were divided into sinoaortic denervation (SAD) and control (C) groups. Baroreflex sensitivity was evaluated by tachycardic and bradycardic responses, induced by vasoactive drugs. Cardiac function was studied by echocardiography and by left ventricle (LV) catheterization.
