Naturally Acquired Humoral Immunity against Malaria Parasites in Non-Human Primates from the Brazilian Amazon, Cerrado and Atlantic Forest.

Plasmodium - Plasmodium brasilianum - P. malariae - P. malariae - P. falciparum - P. vivax - Plasmodium content: - "Non-human primates (NHPs) have been shown to be infected by parasites of the genus " - ", the etiological agent of malaria in humans, creating potential risks of zoonotic transmission. " - ", a parasite species similar to " - " of humans, have been described in NHPs from Central and South America, including Brazil. The merozoite surface protein 1 (MSP1), besides being a malaria vaccine candidate, is highly immunogenic. Due to such properties, we tested this protein for the diagnosis of parasite infection. We used recombinant proteins of " - " MSP1, as well as of " - " and " - ", for the detection of antibodies anti-MSP1 of these parasite species, in the sera of NHPs collected in different regions of Brazil. About 40% of the NHP sera were confirmed as reactive to the proteins of one or more parasite species. A relatively higher number of reactive sera was found in animals from the Atlantic Forest than those from the Amazon region, possibly reflecting the former more intense parasite circulation among NHPs due to their proximity to humans at a higher populational density. The presence of " - " positive NHPs in the surveyed areas, being therefore potential parasite reservoirs, needs to be considered in any malaria surveillance program.

PROMOÇÃO DA SAÚDE NA PERSPECTIVA DO CUIDADO NA ATENÇÃO BÁSICA

  Objective: To discuss the existing literature on health promotion from the perspective of primary care. Methods: This is a qualitative integrative literature review. The search for works involved in the research was carried out in the following databases: SCIELO, LILACS, BDENF and MEDLINE, using the descriptors in health sciences: "Primary care", "Health promotion" and "Public health". The inclusion criteria were: published between 2013 and 2023, with free access to full texts, articles in Portuguese, English and Spanish and related to the theme. Exclusion criteria were: duplicate articles, incomplete articles, abstracts, reviews, debates, articles published in event proceedings and unavailable in full. Results: The aim of health promotion is to have an impact and promote quality of life for all patients in PHC. Another point is the intersectoral and intrasectoral actions that favor the expansion of health awareness. Conclusion: This study showed that primary care is the main intermediary for health promotion actions, where professionals and managers are closest to the population.Objetivo: Discutir por meio da literatura existente acerca da promoção da saúde na perspectiva do cuidado na atenção básica. Métodos: Trata-se de uma revisão integrativa da literatura de caráter qualitativo. A busca dos trabalhos envolvidos na pesquisa foi realizada nas seguintes bases de dados: SCIELO, LILACS, BDENF e MEDLINE, a partir dos descritores em ciências da saúde: “Atenção básica”, “Promoção da saúde” e “Saúde pública”. Os critérios de inclusão foram: publicados no período entre 2013 e 2023, cujo acesso ao periódico era livre aos textos completos, artigos em idioma português, inglês e espanhol e relacionados a temática. Critérios de exclusão foram: artigos duplicados, incompletos, resumos, resenhas, debates, artigos publicados em anais de eventos e indisponíveis na íntegra. Resultados: a promoção da saúde tem como objetivo impactar e favorecer a qualidade de vida a todos os pacientes na APS, outro ponto presente são as ações intersetoriais e intrasetoriais que favorecem a ampliação da consciência sanitária. Conclusão: O presente estudo demonstrou que a atenção básica é a principal intermediadora das ações de promoção à saúde, onde os profissionais e gestores tem a maior aproximação com a população

Silica chemically modified with p-anisidine, p-phenytidine and p-phenylenediamine groups used as adsorbent for pb2+, cu2+, cd2+ and ni2+ in aqueous and ethanol solutions

Silica gel was chemically modified with the aromatic amines p-anisidine, p-phenytidine and p-phenylenediamine, using grafting reactions. The resulting modified silicas were characterized by infrared spectroscopy and N2 adsorption/desorption isotherms. The organic groups were covalently immobilized in a monolayer form. These modified silicas were investigated as adsorbents for Pb2+, Cu2+, Cd2+ and Ni2+ in aqueous and ethanol solutions. In a general way, the adsorption capacity values for all adsorbents presented the following sequence: Pb2+ >> Cu2+~= Cd2+ ~= Ni2+. Adsorption studies for all adsorbents, in competitive medium, showed better selectivity for Cu2+ and Pb2+ in aqueous medium and for Pb2+ in ethanol solution. Desorption studies were carried out using HCl and HNO3 as eluents

Influence of Na, K, Ca and Mg on lead atomization by tungsten coil atomic absorption spectrometry

A atomização de chumbo em atomizador eletrotérmico de filamento de tungstênio, na presença e ausência de altas concentrações de Na+, K+, Ca2+ e Mg2+, foi investigada com o objetivo de entender os processos de interferências. A atomização do chumbo foi menos comprometida por Ca2+ e Mg2+ do que por Na+ e K+. Na ausência dos concomitantes, a eficiência da atomização de chumbo foi melhorada com a presença de H2 (10% v/v) na composição do gás de purga, durante as etapas de pirólise e atomização. As interferências causadas por Na+ e Ca2+ foram desprezíveis quando a etapa de pirólise foi realizada sem o H2 na composição do gás de purga. Os resultados mostraram que Na+, K+, Ca2+ e Mg2+ podem estar diretamente envolvidos nas reações de competição pelo H2 nos processos em fase condensada.The atomization of lead in an electrothermal tungsten coil atomizer in the presence and absence of Na+, K+, Ca2+ and Mg2+ was investigated with the objective of understanding the interference processes. The lead atomization was less affected by Ca2+ and Mg2+ than by Na+ and K+. In the absence of concomitants, lead atomization efficiency was improved by the presence of H2 (10% v/v) in the purge gas composition, during pyrolysis and atomization steps. The interference caused by Na+ and Ca2+ was negligible when the pyrolysis step was accomplished without H2 in the purge gas composition. The results showed that Na+, K+, Ca2+ and Mg2+ are directly involved in competition reactions for H2 in condensed phase
