Immittance response of an electrolytic cell in the presence of adsorption, generation, and recombination of ions
Jamile Lorena de Paula,José Adauto da Cruz,Ervin Kaminski Lenzi,Luiz Roberto Evangelista
Physics , 2012,
Abstract: Effects of the adsorption-desorption process on the immittance response of an electrolytic cell are theoretically investigated in the framework of the diffusional Poisson-Nernst-Planck (PNP) continuum model, when the generation and recombination of ions is taken into account. The analysis is carried out by searching solutions for the drift-diffusion equation coupled to the Poisson's equation relating the effective electric field to the net charge density. The effect of different ion mobilities on the immittance, i.e., situations with equal and different diffusion coefficients for positive and negative ions, are considered. A general exact expression for the admittance in the context of the linear approximation is obtained.
A connection between anomalous Poisson-Nernst-Planck models and equivalent circuits with constant--phase elements
Ervin Kaminski Lenzi,Jamile Lorena de Paula,Fernanda R. G. B. Silva,Luiz Roberto Evangelista
Physics , 2013,
Abstract: A connection between the impedance spectroscopy response of anomalous Poisson-Nernst-Planck (PNPA) diffusional models and of equivalent circuits containing constant phase elements (CPE) is established for a typical electrolytic cell. The analysis is carried out in the limit of low frequency in order to highlight the surface effects and to explore how they can be connected to the presence of CPE in the circuit. It is shown that, depending on the choice of the equivalent circuit, the action of these elements can be the same as the one obtained by using integro-differential boundary conditions to describe anomalous diffusive processes in the framework of PNPA models. The predictions are also compared with an experimental data obtained from an electrolytic solution.

Romina Ceci, Pablo N. de Francesco, Juan M. Mucci, Lorena N. Cancelarich, Carlos A. Fossati, Paula A. Rozenfeld
Advances in Biological Chemistry (ABC) , 2011, DOI: 10.4236/abc.2011.13008
Abstract: Introduction: Lysosomal storage disorders (LSD) are inherited diseases caused, in the majority of them, by the deficiency of lysosomal enzymatic activities. Ob-jectives: We aimed to analyze the usefulness of DBS samples for diagnosis of 4 LSDs, with the availability of a large quantity of patient samples. Design and methods: Blood samples from previously diagnosed patients with Fabry, Gaucher, Hunter, and Maro-teaux-Lamy syndromes and normal control individ-uals, were collected and dispen-sed in filter paper, and used for enzymatic activity determination. Results: Diagnosis of hemi/homo-zygous patients with Fabry, Hunter and Maroteaux-Lamy diseases using DBS samples showed ideal parameters of 100% sensitivity and specificity. DBS assay for Gaucher disease would need a posterior confirmatory step. Conclusions: Leukocyte measu-rement is the only reliable way to diagnose Gaucher disease. For Hunter, Fabry and Maroteaux-Lamy disorders discrimination between patients and controls seems adequate by DBS.

Abstract: objective: this cross-sectional and qualitative study analyzes the use of regional foods and preparations in the school menus of brazilian public schools, as well as their frequency and the presence of dietitians. methods: the analyzed menus had been officially requested by the governmental area related to education in brazil to the cities and the states of the entire country. for the sample, of the 2,962 menus received, 370 were analyzed, distributed proportionally by brazilian regions. the criterion was the menus of the elementary schools located in urban areas. results: from the analyzed menus, 63 to 87.8% were made by dietitians. among the regions, the south region stood out since 86.5% of the menus had at least one regional food per week. however, in the north region, the percentage of regional preparations dropped to 38%. furthermore, this region had the smallest relation between the number of menus prepared by dieticians and the number of regional preparations, while the south region had the greatest. conclusion: the professionals in charge of the national school food program need to encourage and consider typical regional preparations by including them in school menus and strengthen the monitoring of this practice.
Evaluation of the immune response to CRA and FRA recombinant antigens of Trypanosoma cruzi in C57BL/6 mice
Pereira Valéria Rêgo Alves,Lorena Virginia Maria Barros de,Nakazawa Mineo,Silva Ana Paula Galv?o da
Revista da Sociedade Brasileira de Medicina Tropical , 2003,
Abstract: Humoral and cellular immune responses were evaluated in 44 C57BL/6 mice immunized with the Trypanosoma cruzi recombinant antigens CRA and FRA. Both antigens induced cutaneous immediate-type hypersensitivity response. The levels of IgG1, IgG2a, IgG2b and IgG3 were high in CRA immunized mice. IgG3 was the predominant isotype. Although no difference in antibody levels was observed in FRA-immunized mice when compared to control mice, both antigens were able to induce lymphoproliferation in immunized mice. Significant differences were observed between incorporation of [3H]- thymidine by spleen cell stimulated in vitro with CRA or FRA and the control group. These results suggest that CRA and FRA could be involved in mechanisms of resistance to Trypanosoma cruzi infection.

Castro, Jamile Claro de;Clapis, Maria José;
Revista Latino-Americana de Enfermagem , 2005, DOI: 10.1590/S0104-11692005000600007
Abstract: this qualitative study aimed at identifying how obstetrical nurses perceive the humanization of delivery care, as well as evidencing, based on their discourse, the actions they develop during the birth process and factors that complicate the implementation of this care. study participants were 16 nurses from a maternity in the interior of s?o paulo, brazil. following the collective subject discourse framework, data were collected by using semistructured interviews that were recorded, transcribed and organized for tabulation and analysis. the results show that, according to these nurses, the humanization process happened as a political strategy for improving care and rescuing normal birth. they believe there is a need to change the paradigm for the process to be concretized. these results also showed that nurses are more integrated with humanized birth as a process, and not as an event.
