RESUMO

In this work the magnetic properties of bimetallic phases M'0.2Mn0.8PS3·0.25H2O (M' = CoII, NiII, CuII or ZnII) have been explored and compared with those of the pristine phase MnPS3. Magnetic susceptibility, high field magnetization and electron paramagnetic resonance (EPR) studies reveal that the transition temperature between the antiferromagnetic and paramagnetic order for the pristine phase is shifted to lower values in the bimetallic phases. From magnetization measurements the critical field of the spin-flop transition is found to be dependent on the nature of the added secondary transition metal ion. EPR spectra of all compounds in the temperature range of 8-300 K present a single resonance line shape. Temperature dependence of the EPR parameters, like line width, g values and double integrated area (IDIN), are obtained from the spectra and present a scenario compatible with the magnetization results. The temperature dependence of the first derivative of the product (IDINT) shows two maxima for all samples, with exception of the CoII phase, indicating two critical temperatures, while these critical temperatures could not be clearly determined by dc susceptibility.

RESUMO

Las mujeres menopáusicas y premenopáusicas de entre 45 y 65 años tienen conocimiento del aumento de los factores de riesgo cardiovascular en el climaterio; sin embargo, la despreocupación que muestran por el control de esos factores hace necesario desarrollar una educación sanitaria dirigida a mujeres de mediana edad. Objetivo: Valorar el grado de conocimiento y de control de los factores de riesgo cardiovascular, y en especial las dislipemias, en mujeres de 45 a 65 años, a fin de diseñar una atención farmacéutica eficaz (AU)


Menopausal and pre-menopausal women aged 45 to 65 are aware of the increase in cardiovascular risk factors during menopause. However, they disregard this circumstance and, given their lack of concern about controlling them, it is necessary to develop health education focused on middle-aged women. Objective: To evaluate the degree of knowledge and control of cardiovascular risk factors in women aged 45 to 65, focusing on dyslipidemias, for the purpose of designing effective pharmaceutical care (AU)

RESUMO

Two quantum chemistry theoretical models in the gas phase at the density functional theory B3LYP/LACVP(d) level of calculation are proposed to rationalize the hydrazine oxidation by cobalt(II) phthalocyanine (Co(II)Pc). This oxidation reaction involves the net transfer of four electrons. These theoretical models that are described in terms of energy profiles include a through-space mechanism for the transfer of the first electron of the hydrazine and a through-bond mechanism proposed for the transfer of the three electrons remaining. The main difference between both models arises from a one-electron and one-proton alternate transfer for model 1 and a two-electron and two-proton alternate transfer for model 2. The main problem for experimental studies is to determine if the first transfer corresponds to an electron or a chemical transfer. Under this point of view, we proposed two models which deal with this problem. We conclude that model 1 is more reasonable than model 2 because the whole oxidation process is always exergonic.
