Chemical Constituents from Caesalpinia férrea: Identification and 1H and 13C Resonance Assignment  [PDF]
Islay Lima Magalhes, Francisco Chagas Lima Pinto, Raimundo Braz Filho, Daniele Alves Ferreira, Telma Leda Gomes de Lemos, Francisco José Queiroz Monte
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.510077
Abstract: In a phytochemical investigation of Caesalpinia ferrea (Leguminosae), four aromatic compounds (1-4) have been isolated and identified. Their structures have been assigned based on data provided by spectroscopic techniques, including 2D NMR experiments. Compounds 3 and 4 are being reported for the first time for Cesalpina ferrea.

Magalhes, Vera;Magalhes, Marcelo;Lima, Roberto A.;Tateno, Seiki;Magalhes, Eduardo;
Revista do Instituto de Medicina Tropical de S?o Paulo , 1992, DOI: 10.1590/S0036-46651992000200008
Abstract: of 3250 diarrheal stools received for microbiologic diagnosis at a private clinical laboratory in recife, brazil, strains of vibrio were isolated from 55 (1.7%). the study was carried out from may 1989 through may 1991. for recovering vibrio, fecal samples were enriched in alkaline peptone water supplemented with 2% nacl and subcultured on thiosulfate-citrate-bile salts-sucrose agar (tcbs). of the recovered species, v. parahaemolyticus was most commonly found (24 strains), followed by v. furnissii (15 strains), v. cholerae non-01 (6 strains), v. alginolyticus (4 strains), v. fluvialis (2 strains), and vibrio sp. (1 strain). the low isolation rate of vibrio raises doubts about the cost-effectiveness of the use of tcbs in the routine enterobacteriologic workup of clinical laboratories

From Phylogeny to Ontogeny of Longevity: Contributions of the Evolutionary Approach to Gerontology  [PDF]
Rodolfo Gomes do Nascimento, Jeisiane Lima Brito, Celina Maria Colino Magalhes
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.610123
Abstract: This qualitative study aimed at performing a theoretical review and understanding the phylogenic aspects and the story of the ontogenic development of human longevity, in addition to proposing a brief reflection about the role of old age in an evolutionary perspective based on the theoretical references of Ethology, Evolutionary Developmental Psychology, and Gerontology. This is a narrative review based on national and international publications selected from journals and books indexed online which were accessed by the following database: Lilacs, Google Scholar, and Scielo, with a 55-year period range for the search (1957 to 2012) through the combined descriptors: longevity, aging, evolutionary psychology, phylogeny, and ontogeny. According to the inclusion criteria, 43 publications were analyzed through the Content Analysis and discusses in three categories: distal causal mechanism of human longevity, approaching the enlargement of the stages of life, and theories that discuss the reproductive role of the species; proximal causal mechanisms, built along life and the evolutionary role of aging with its importance for the species in the attempt to amplify the meanings of this stage of life in the Gerontology field. Faced with the discussion, we perceived that the study of the determinants of human longevity (in their phylogenetic and ontogenetic dimensions) is consistent and represents an important model for a broader and deeper understanding.
Vibrio metschnikovii among diarrheal patients during cholera epidemic in Recife Brazil
Magalhes, Vera;Branco, Adeíza;Lima, Roberto de Andrade;Magalhes, Marcelo;
Revista do Instituto de Medicina Tropical de S?o Paulo , 1996, DOI: 10.1590/S0036-46651996000100001
Abstract: although known since the last century, vibrio metschnikovii was only appropriately described and recognized as a new species within the genus vibrio in 1978. rarely is the organism linked to human disease. only once has v. metschnikovii been incriminated as responsible for human diarrhea, and affecting an old woman who suffered from diabetes and had a hepatoma. during the first two years of the present cholera epidemic, which reached recife in march, 1992, we screened for vibrio nearly 4000 diarrheal fecal specimens submitted to a private clinical laboratory for detection of enteropathogenic microorganisms. now, we report six cases of diarrhea associated with v. metschnikovii affecting individuals not suffering of any apparent underlying systemic illness.
Gastroenteritis humanas associadas a Vibrio parahaemolyticus no Recife, Brasil
Magalhes, Vera;Lima, Roberto A.;Tateno, Seiki;Magalhes, Marcelo;
Revista do Instituto de Medicina Tropical de S?o Paulo , 1991, DOI: 10.1590/S0036-46651991000100012
Abstract: a study was carried out on the occurrence of vibrio parahaemolyticus in 1.100 diarrheal feces, routinely sent to a private clinical laboratory for microbiologic diagnosis, in recife. v. parahaemolyticus was isolated from 14 (1.3%) fecal samples. however, if we considered only the specimens from adult patients, the isolation rate of v. parahaemolyticus rose to 7.1%. in most cases (92.86%), v. parahaemolyticus was the only enteropathogen recognized. among the isolates, seven k antigen serovars were demonstrated, and three were untypable. only two human isolates, both ureolytic, did not produce the thermostable direct hemolysin. we concluded that v. parahaemolyticus is an important cause of sea food linked diarrhea among adults in recife.
Reasons for Reading in Infancy and the Child’s Development under the Light of Historical-Cultural Theory: A Path to Understand the Development of the Reading Ability in Childhood  [PDF]
Cyntia G. G. Sim?es Girotto, Sandra Aparecida Pires Franco, Cassiana Magalhes, Greice Ferreira da Silva, Ana Claudia Bazé de Lima, Daniele Aparecida Russo, Andressa Cristina Molinari
Creative Education (CE) , 2017, DOI: 10.4236/ce.2017.86072
Abstract: This essay is a bibliographical-theoretical research that focuses on understanding the reasons and the conditions necessary for the development of the reading ability since infancy and its relation to the child’s development. Thus, it aims at comprehending the process of literacy learning in teaching and in learning the ability to read since infancy. The objectives and methodology meant to understand the relationship between written language, reading and the development of early readers in their relation to the book. For achieving that, we considered the concept of what a child is, of a child’s development, of the reading ability, and the formation of the early reader as the basis for the discussion, under Historical-Cultural Theory. The results show that when a child is treated as an individual who is beyond classification and categorization—which establishes a child’s development as a linear process defined by nature—to view her as an individual that constructs thoughts, language, imagination, and affect, thus constructing the self, in its life history and in the rela-tions with the other.

Abstract: knowledge concerning work-related hazards and accidents among adolescents enrolled in an elementary public school was evaluated through an analysis of their occupational profile and discussions concerning concepts of risk situations at work and individual and collective measures for accident prevention and control. the results included a significant change in their understanding of work-related accidents as identified by statistical tests comparing the proportion of correct answers in a questionnaire applied prior to and at two moments after the intervention.
O mecanismo de autopropuls?o de vórtices oceanicos: uma revis?o
Azevedo, José Luiz Lima de;Mata, Mauricio Magalhes;
Revista Brasileira de Geofísica , 2010, DOI: 10.1590/S0102-261X2010000300002
Abstract: oceanic eddies are effective carriers of momentum, mass, heat, of chemical and biological characteristics associated generally with their place of origin. these features exercise influence on global circulation, in the distribution of large-scale water masses and in the biology of the oceans. this influence does not only involve the transfer of energy and properties associated with the place of origin of the eddy but also their strong performance in mixing processes. the motion of eddies across the oceans are primarily driven by three factors: the self-propulsion which is intrinsic to the feature and moves it towards the west; the advection by others currents and the influence of eddies nearby. this work focuses on the first point, where the self-propulsion of isolated eddies is widely reviewed and discussed. the expression that allows the approximate calculation of the translation speed of isolated vortices is deduced. the basic equations (shallow water, the bernoulli function and integrated meridional momentum) required for this development are presented and discussed as well as the meridional forces that act on these features in motion, where the mathematical formalism associated with each of them is also reviewed. this review shows that all isolated vortices are self-propelled towards the west, regardless of the hemisphere considered. it also shows that three meridional forces act on the eddies in motion: (1) the β force, due to the difference of the coriolis parameter between the northern and southern hemispheres of the eddy, (2) the coriolis force and the (3) ambient force, due to the action of the external fluid on the isolated eddy. several analyses can be made with respect to these forces and this review also presents, as an example, a comparison of the β forces acting in anticyclonic and cyclonic eddies, with the same characteristics, moving in the southern hemisphere. it is concluded that the β force in the former is greater than the force in the latter.
