Recent Hyper Rayleigh Scattering measurements report a significant increase of second-order hyperpolarizability upon introduction of positive charges at the pyridyl end groups in trispyridyl octopolar chromophores. We calculated the geometries, linear response, and first-order hyperpolarizabilities of a series of six trispyridyl molecules both in the neutral and protonated forms. The calculations were performed...
Summary. Following on from previous work, the temporal and spatial accumulation of the aspartic proteinases (EC 3.4.23) cardosin A and cardosin B during postembryonic seed development of cardoon (Cynara cardunculus) was studied. mRNA and protein analyses of both cardosins suggested that the proteins accumulate during seed maturation, and that cardosin A is later synthesised de novo at the time of radicle emerg...
A sociedade actual, marcada por grandes transformações científico-tecnológicas, sociais e políticas, vê-se cada vez mais confrontada com a necessidade de reintroduzir ou acentuar a formação no domínio moral e cívico. Como agente por excelência de socialização das gerações, a escola desempenha um importante papel neste contexto, assumindo um peso cada vez maior com o alargamento do tempo de permanência das crian...
Mumps is a disease caused by paramyxovirus, whose notification to health authorities is mandatory. Vaccination in Portugal was started in 1987. There have been several outbreaks worldwide, even in populations with high vaccination rates, but none were reported in maternity hospitals. We report the case of a 36 year-old primigravida, admitted in the 37th week of pregnancy, because of fever, painful uterine contr...
Aim: To ascertain the prevalence of inter-arm blood pressure difference in excess of 10 mmHg in pregnant women. Population: A total of 114 pregnant women selected at random from those admitted to our Maternal and Fetal Medicine Unit. Design: Prospective, descriptive study. Methods: Blood pressure was measured on both arms twice (same operator, method and equipment). Other variants analysed were maternal age, ad...
Polygala paniculata L. (Polygalaceae) é uma erva que ocorre em todas as regiões do Brasil. No presente trabalho, foram avaliadas as atividades analgésica, através do teste da placa quente, da retirada de cauda e da formalina, e antiedematogênica, através do teste do edema de orelha induzido por óleo de cróton, dos extratos etanólicos obtidos das partes aéreas de Polygala paniculata selvagem e cultivadas por mic...
Foram realizados dois experimentos de campo nas Fazendas Experimentais da EPAMIG (MG) em um Latossolo Vermelho distroférrico (LVdf) de São Sebastião do Paraíso e Latossolo Vermelho-Amarelo distrófico (LVAd) de Patrocínio, com o objetivo de avaliar o estado nutricional do cafeeiro por meio do índice de balanço nutricional fornecido pelo DRIS, em resposta à adubação potássica. Os experimentos foram instalados, ut...
Early identification of patients who need hospitalization or patients who should be discharged would be helpful for the management of acute asthma in the emergency room. The objective of the present study was to examine the clinical and pulmonary functional measures used during the first hour of assessment of acute asthma in the emergency room in order to predict the outcome. We evaluated 88 patients. The inclu...
Com o objetivo de identificar e quantificar os ácidos orgânicos na rizosfera de plantas daninhas encontradas em lavouras cafeeiras, foram coletadas amostras de rizosfera de Bidens pilosa (picão-preto), Alternanthera ficoidea (apaga-fogo), Taraxacum officinale (dente-de-leão) Amaranthus deflexus (caruru), na Fazenda Experimental da EPAMIG (Empresa de Pesquisa Agropecuária de Minas Gerais), em Lavras-MG, as quais...
The capacity of a given natural ecosystem to provide certain goods and services that satisfy human needs depends on its environmental characteristics (natural processes and components). It was described the availability of these goods and services (environmental functions) controlled and sustained by ecological processes operating in Ecological Station of Jataí (Luiz Antônio, SP). The environmental functions id...
