A percepção dolorosa, avaliada funcionalmente através do sistema analgésico endógeno, reflete a atividade nociceptivo, o qual depende nível de excitabilidade nervoso, portanto, procura vias e formas que reduzam deste tornou-se uma preocupação humana para assim aliviar da dor. Objetivo: Determinar limiar excitação nociceptivo em animais (camundongos) submetidos tratamento com diferentes doses cl...

To understand the initial hydration processes of MgCl2, we measured photoelectron spectra of MgCl2(H2O)n- (n = 0-6) and conducted ab initio calculations on MgCl2(H2O)n- and their neutral counterparts up to n = 7. A dramatic drop in the vertical detachment energy (VDE) was observed upon addition of the first water molecule to bare MgCl2-. This large variation in VDE can be associated with the ch...

Magnesium chloride (MgCl2) is commonly used as a general anesthetic in cephalopods, but its physiological effects including those at cardiac level are not well-characterized. We used an in vitro isolated perfused systemic heart preparation from the common octopus, Octopus vulgaris, to investigate: (a) if in vivo exposure to MgCl2 formulations had an effect on cardiac function in vitro and, if s...

Natural Zn reserves might be exhausted in the following decades. Electric arc furnace (EAF) dust is an essential secondary resource. The recovery of from EAF a critical factor sustainable development industry and steelmaking industry. Efficient destruction ZnFe2O4 crystal structure separation Fe are key issues to recycle dust. Molten metal chlorides believed effective breaking ZnFe2O4. This wor...

BACKGROUND Pulmonary hypertension results in increased morbidity and mortality in children after surgical repair of congenital heart defects. Various vasodilators have been unsuccessful in providing preferential pulmonary vasodilation in these patients. Identification of a more preferential pulmonary vasodilator would improve the assessment, management, and outcome of these children. To determi...

Understanding the structure and properties of MgCl2/TiCl4 nanoclusters is a key to uncovering origin Ziegler–Natta catalysis. In particular, vibrational spectroscopy can sensitively probe morphology active species MgCl2/TiCl4. Here, we determined spectroscopic fingerprints 50MgCl2 50MgCl2/3TiCl4 which were obtained by nonempirical determination based on an evolutionary algorithm DFT. The adsorp...
