Laços familiares e aspectos materiais da dinâmica mercantil na cidade de São Paulo (séculos XVIII e XIX)

A partir das relações familiares estabelecidas no seio do grupo mercantil ativo na cidade de São Paulo ao longo dos séculos XVIII e XIX, pretende-se narrar as trajetórias de vida de nove agentes comerciais envolvidos nas alianças matrimoniais, destacando os negócios realizados, a atuação sociopolítica e o encaminhamento dado aos descendentes. Em seguida, busca-se articular o desenvolvimento urbano do centro da capital com a atuação destes homens de negócio, concentrando as análises sobre aspectos da vida material relacionados às suas moradias e ao mobiliário existente no espaço doméstico.

Determinação de As, Cd e Pb em amêndoas e mesocarpo de babaçu, sapucaia, xixá e castanha-do-pará por espectrometria de absorção atômica

This work describes methods for the simultaneous determination of Cd and Pb by graphite furnace atomic absorption spectrometry and As by hydride generation atomic absorption spectrometry in Brazilian nuts. The samples (~ 0.300 g) were digested to clear solutions in a closed vessel microwave oven. The pyrolysis and atomization temperatures for simultaneous determinations of Cd and Pb were 1100 and 2100 °C, respectively, using 0.5% (w v-1) NH4H2PO4 + 0.03% (w v-1) Mg(NO3)2 as chemical modifier. The limits of detection (3Δ) were 3.8 μg kg-1 for As, 0.86 μg kg-1 for Cd and 13 μg kg-1 for Pb. The reliability of the entire procedures was confirmed by peach leaves (No. 1547 - NIST) certified reference material analysis and addition and recovery tests. The found concentrations presented no statistical differences at the 95% confidence level.

Insetos em presépios e as "formigas vestidas" de Jules Martin (1832-1906): uma curiosa manufatura paulistana do final do século XIX

Encontrados no Brasil desde os primórdios da colonização portuguesa, os presépios logo tiveram de adaptar-se à realidade local, circunstância muito propícia ao aparecimento de concepções heterodoxas e ao emprego de elementos exóticos da fauna e flora de cada região. Como registros envolvendo insetos são muito pouco comuns, chama a atenção que fêmeas de saúva, Atta sp. (Hymenoptera, Formicidae), tenham sido aproveitadas na composição de presépios no estado de São Paulo. Tendo subsistido pelo menos até a década 1960, os "presépios de formigas" existentes em cidades como Embu das Artes poderiam estar relacionados às "formigas vestidas" criadas por Jules Martin, curiosa manufatura paulistana do último quartel do século XIX.

Evaluation of pharmacotherapy on elderly residents of nursing homes in the north-east of Brazil

Data related to medication order and the use of medications was collected from 94 elderly medical records of two nursing homes of Aracaju (SE), The mean age was 83.2 (SD = 10.1), with most belonging to the females (63.8%). The prevalence of the use of drugs was 87.2% and the average of medicines consumed was equal to 2.7 (SD = 1.8), mainly with action in the cardiovascular and nervous systems. In this Study, the elderly population studied presented polypharmacy (18.1%), inappropriate use of drugs (28.7%) and double therapy (11.7%). Data showed the need for improvement and evaluation of the quality of pharmacotherapy to promote rational drug use in the elderly population.

Aluminum Concentrations in Water of Elderly People`s Houses and Retirement Homes and Its Relation with Elderly Health

The purpose of this study was to determine the concentrations of aluminum (Al) and other metals in water samples from elderly people`s houses and retirement homes. Forty-six duplicate water samples from kitchen taps were collected in Ribeiro Preto/SP, Brazil. Metal levels were measured by atomic absorption spectrophotometer. Aluminum concentration exceeded the maximum allowed values in 26% of samples according to the Decree 518/2004 of the Brazilian Health Ministry. It was noted that 11% of elderly living at monitored houses, as well as 19% living at retirement homes presented Alzheimer disease diagnostic. These results suggest taking into account Al risks among vulnerable elderly population groups.
