A idéia de império e a fundação da monarquia constitucional no Brasil (Portugal-Brasil, 1772-1824)

Cet article met les conceptions et projets politiques ayant trait au processus conduisant à la constituion impériale brésilienne de 1824 dans un contexte historique dont le pont de départ est la notion d'empire civil, telle qu'elle se développa lors de la réorganisation politico-administrative du royaume et de l'empire du Portugal au XVIIIe siècle. Le texte montre qu'avec le couronnement de Pierre I on fit un usage moderne d'une institution ancienne, le sacre royal, ce qui servit à étayer une sujection politique fondée sur la raison universelle humaine. Cette étude permet de comprendre pourquoi le Brésil indépendant fut pour commencer un empire, pas un royaume, ainsi que le sens profond du pouvoir modérateur attribué à l'empereur par la constitution de 1824.

Hemoglobin as AS/alfa talassemia - Importância diagnóstica

Sickle Cell disease is a generic term for a group of genetic disorders characterized by the predominance of hemoglobin S. These disorders include Sickle Cell anemia, the Sickle Cell beta Thalassemia syndromes and Hemoglobinopathies in which hemoglobin S is in association with another abnormal hemoglobin, such as hemoglobin S/C. The Sickle Cell trait (hemoglobin AS) associated with Alpha Thalassemia presents alterations in the red blood cells morphology, usually absent in the heterozygous for this hemoglobin variant. The interaction between hemoglobin Sand alpha Thalassemia has been described as one of the factors responsible for the improvement in the clinical picture of homozygous of hemoglobin S (Sickle Cell Anemia), decreasing the number of episodes of pain. The genetic mechanisms of this influence are evaluated using molecular analyses of the human globin genes. With the objective of verifying the presence of alpha Thalassemia in heterozygous of hemoglobin S, with anemia, sent to the Laboratory of Hemoglobins, Department of Biology, UNESP, São José do Rio Preto, SP, we analyzed 1002 blood samples with Sickle Cell trait, in the period from 1990 to 1998. The samples were picked with EDTA 5% as anticoagulant, after previous authorization of the carriers. Appropriated counseling and management requires definitive diagnosis. For the laboratorial diagnosis the blood samples were submitted to electrophoretic procedures in alkaline and acid pH and cytological evaluation of hemoglobin H. The electrophoretic procedures confirmed the presence of hemoglobin AS. The cytological evaluation evidenced the presence of alpha Thalassemia. Of this total analyzed, 16(1,59%) blood samples presented the association between hemoglobin AS and alpha Thalassemia and two individuals belonged of the same family. Our results addressed us to suggest to the routine laboratories, that is important to accomplish the research of alpha Thalassemia among the Sickle Cell trait, with anemia, to verify the interaction with alpha Thalassemia, supplying to the carriers a important information on its hematological profile, genetic pattern of hemoglobinopathies and the appropriated counseling.

Hemoglobinas anormais e dificuldade diagnóstica

The human hemoglobins, with genetically defined inheritance patterns, have shown characteristic polymorphic variation within the Brazilian population, depending on the racial groups of each region. They have appeared under the form of hemoglobin variants or thalassemias, the variant types S and C and the alpha and beta thalassemias being more common, all of them in heterozygote form. During the year of 1999, blood samples from 506 individuals, with suspected anemia or that had already passed through hemoglobinopathies screening, were sent to the Hemoglobin Reference Center - UNESP for diagnostic confirmation and submitted to electrophoresis proceedings, biochemical and cytological analyses in order to characterize the type of abnormal hemoglobins. The goal of the present study was to verify which abnormal hemoglobin types show greater diagnostic difficulty. The samples came from 24 cities in twelve states. The results showed that 354 (69.96%) individuals presented abnormal hemoglobins, 30 (5.93%) being Hb AS, 5 (0.98%) being Hb AC, 76 (15.02%) suggestive of heterozygote alpha thalassemia, 134 (26.48%) suggestive of heterozygote beta thalassemia and 109 (21.54%) with other forms of abnormal hemoglobin, including rare variants and different forms of thalassemias and variant hemoglobin interactions. It has been concluded that, despite the improved techniques currently available and a constant influx of capacitated personnel, the heterozygote form of thalassemias (210 individuals -41.50%) is challenging to diagnose, followed in difficulty by rare variant characterization and interactive forms of hemoglobinopathies (109 individuals-21,54%), suggesting that the capacity for production of qualified professionals and information about these genetic changes in our population should be increased.

Reversible Hamiltonian Liapunov center theorem

We study the existence of periodic solutions in the neighbourhood of symmetric (partially) elliptic equilibria in purely reversible Hamiltonian vector fields. These are Hamiltonian vector fields with an involutory reversing symmetry R. We contrast the cases where R acts symplectically and anti-symplectically. In case R acts anti-symplectically, generically purely imaginary eigenvalues are isolated, and the equilibrium is contained in a local two-dimensional invariant manifold containing symmetric periodic solutions encircling the equilibrium point. In case R acts symplectically, generically purely imaginary eigenvalues are doubly degenerate, and the equilibrium is contained in two two-dimensional invariant manifolds containing nonsymmetric periodic solutions encircling the equilibrium point. In addition, there exists a three-dimensional invariant surface containing a two-parameter family of symmetric periodic solutions.

Evaluation of ornamental grasses submitted to water stress

The work was carried out at the College of Agricultural and Veterinary Sciences of the State University of São Paulo (UNESP/FCAV), Campus of Jaboticabal, Brazil, aiming to study the tolerance response to water stress and capacity of regeneration after mowing three different ornamental grasses used in Brazilian landscaping: Imperial zoysia grass (Zoysia japonica 'Imperial'), zoysia grass (Zoysia japonica) and St. Augustine grass (Stenotaphrum secundatum). The experimental design was entirely randomized in a factorial scheme 33 (three grass species: Zoysia japonica 'Imperial', Zoysia japonica and Stenotaphrum secundatum; in three water stress conditions: under full sun, with and without irrigation, and under greenhouse conditions without irrigation) with four replications per plot. The irrigation was performed using microsprinklers with a flow of 0.28 L s-1, and the grasses of all plots were mowed monthly. The evaluations were executed monthly, before mowing the grass, in the beginning of each season, that means, in October (for Spring evaluation), January (for Summer), April (for Autumn) and July (for Winter), considering the Brazilian climate conditions. The evaluated parameters were shoot height and total dry mass. The data were submitted to the variance analysis and the means were compared by the Tukey test at 5% confidence level. The grasses grown under greenhouse conditions, without irrigation, showed higher height and lower dry mass weight averages, what possibly indicates that the plants etiolated. The grasses grown under full sun, either with or without irrigation, showed a similar plant development. The S. secundatum species showed greater tolerance to water stress in October, month that followed the longest dry period. The total dry mass was gradually reduced during the experiment for all grasses grown under greenhouse conditions without irrigation; however, a great general tolerance to water stress was observed for all grasses because all of them survived along nine months without irrigation.
