Abstract: Henoch-Schönlein purpura is a vasculitis of small vessels, characterized by tissue deposition of IgA, affecting predominantly the skin, intestine, joints and kidneys. It mainly affects the pediatric age group, especially from 2 to 11 years old. Most often, it is preceded by episode of upper airway infection from days to weeks. The most common clinical manifestations are purpuric cutaneous lesions located in the lower limbs and buttocks, abdominal pain in colic, nausea, vomiting, diarrhea, in addition to arthralgia/arthritis, usually with spontaneous resolution. Renal impairment usually manifests with hematuria and proteinuria, and renal function may also be impaired. The case described refers to a female patient, 86 years old, with a previous history of infection of the upper airways, followed by purpura in the lower limbs and renal impairment: serum creatinine 3.1 mg/dL (N 0.5 - 1.2 mg/dL); glomerular filtration rate 15 ml/min (N > 60 ml/min); urea 118 mg/dL (N < 40 g/dL); proteinuria 4.497 mg/24h. The present report aims to draw attention to the occurrence of Henoch-Schönlein purpura in an atypical age group, with significant renal impairment, improvement only with conservative treatment, thus avoiding the use of immunosuppressants and the risks of immunosuppression and toxicity related to such drugs.

Delsarte and Laban: the origins and principles of an aesthetic revolution
S?nia Machado de Azevedo
Revista Brasileira de Estudos da Presen?a , 2012,
Abstract: This text establishes a link between some principles of the work of Fran ois Delsarte and Rudolf Laban, concluding that what identifies them is closely connected with the research method, which is based on the observation of human nature and human beings in real life and in art. It also shows that the principles of the method proposed by Delsarte are part of the contemporary scene and of different forms of pedagogy connected to this very same scene.
Impacto da temperatura e da defesa da presa na utiliza??o de Tenebrio molitor L. por ninfas do predador Supputius cincticeps (Heteroptera:Pentatomidae)
Azevedo, Francisco R. de;Ramalho, Francisco S.;
Anais da Sociedade Entomológica do Brasil , 1999, DOI: 10.1590/S0301-80591999000100012
Abstract: the effects of the temperature and of the prey defense on the utilization of tenebrio molitor l. larvae by the nymphs of the predator supputius cincticeps (st?l) were studied. growth of s. cincticeps was function of the prey defense and/or temperature. the relative consumption rate of t. molitor larvae by s. cincticeps depended on the instar of the predator and on the temperature, and also on the defense behavior of the prey. the efficiency of conversion of t. molitor larvae ingested by nymphs of s. cincticeps depended upon the predator instar, temperature and defense of the prey. the relative growth rate of s. cincticeps was related to predator instar and temperature, and predator instar and defense of the prey.

A Política da Reforma Tributária: Federalismo e Mudan?a Constitucional
Azevedo, Sérgio de;Melo, Marcus André;
Revista Brasileira de Ciências Sociais , 1997, DOI: 10.1590/S0102-69091997000300006
Abstract: the article analyses the characteristics of the decision-making process of tax reforms. at the empirical level, it focuses on the patterns of political interaction among political actors with specific reference to recent reforms in brazil. the reform arena is described as exhibiting great technical complexity and medium political salience, and involving basically bureaucratic elites and state governors. the author concludes that the recent deadlock in tax reform can be explained by the consociational elements of the brazilian political system, by the "political geometry of reform losses", and by collective action problems encountered by state governors. it is further argued that governors face a "prisoner's dilemma" type of incentive structure.
Behavioural responses of captive-born greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae) submitted to antipredator training
Azevedo, Cristiano S. de;Young, Robert J.;
Revista Brasileira de Zoologia , 2006, DOI: 10.1590/S0101-81752006000100010
Abstract: human activities have been diminishing greater rhea rhea americana (linnaeus, 1758) populations throughout their natural distribution. the reintroductions of captive-born greater rheas have been tried but without success; since the individuals reintroduced were killed by predators. captive-born animals that have been isolated from predators for many generations can lose their predator recognition abilities. to enhance the survival rates of the reintroduced animals, researchers are now using antipredator training techniques. we studied the response of 15 zoo-borne greater rheas to antipredator training. the animals were divided into three groups: two test groups and one control group. we ran 15 antipredator tests and four control testes with each group. antipredator tests consisted of pairing a taxidermized predator model or a real predator (domestic dog) with a simulation of a capture procedure. control tests consisted of presenting the predator model (jaguar) to the birds, after training but not associating it with an aversive event and recording behavioural responses. all tests were video-recorded and analysed a posteriori. results showed that the trained rheas responded appropriately to the predators, becoming more vigilant and that there was considerable individual differences in response to antipredator training. the results demonstrated that antipredator training is effective and therefore an invaluable tool for reintroduction projects involving greater rheas. furthermore, the methods employed in this research project should be applicable to other species of flightless birds.
Shyness and boldness in greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae): the effects of antipredator training on the personality of the birds
Azevedo, Cristiano S. de;Young, Robert J.;
Revista Brasileira de Zoologia , 2006, DOI: 10.1590/S0101-81752006000100012
Abstract: the shy-bold continuum is an axis of behavioural variation for some species, but the consequences of shyness and boldness in antipredatory behaviour is unknown. bold animals have the tendency to be predated first after release in comparison to shy animals, who naturally avoid the predators. antipredatory training has been used to enhance the defence behaviours of naive animals by various researchers around the world. for greater rheas, rhea americana (linnaeus, 1758), this kind of study is pioneer. in this study we have investigated if there are relationships between personality and performance of greater rheas in antipredatory training. we also investigated if the training procedures influenced the behaviour of the birds when presented to novel objects. fifteen zoo-borne greater rheas were studied and 16 personality tests were run, being eight before the application of antipredator training, and eight after the training. we presented to the birds four novel objects (ball, box, bag and person) and recorded their behaviour and the distance of the birds in relation to the objects. results showed that the birds behave boldly before training and shyly after it. the antipredator training modified significantly the behaviour of the rheas, making them more careful about novel situations. personalities affected the behaviour of the birds during antipredator training. the study of the animal personalities can be an useful tool in reintroduction programs since it helps to choose the animals with the highest chance of survival to reintroduce.
Do captive-born greater rheas Rhea americana Linnaeus (Rheiformes, Rheidae) remember antipredator training?
Azevedo, Cristiano S. de;Young, Robert J.;
Revista Brasileira de Zoologia , 2006, DOI: 10.1590/S0101-81752006000100011
Abstract: the antipredator training is a powerful tool now being used to help the reintroduced animals to recognise and escape from their predators. testing the memory capacity of the animals after antipredator training is important to evaluate if the application of the training is worthwhile. a group of 15 captive-born greater rheas was studied at belo horizonte zoo. eight birds were antipredator trained and seven birds were not. after the end of the antipredator training sessions, we run four memory tests at 40, 55, 70 and 88 days after training was completed. the memory tests consisted of showing a predator model to the rheas and recording their behavioural responses. it was measured the capacity of antipredator information storage, the influence of the group size on the behaviour of the birds and the influence of the antipredator training on the elicitation of the correct behavioural responses of the birds when confronted by a predator. the results showed that the rheas retained predator recognition for almost three months, that the group size affected the responses of the birds (more defence behaviours expressed when tested alone) and that the antipredator training is essential to elicit the adequate antipredatory responses, since untrained birds behaved in a tranquil manner when confronted by a predator model. we concluded that antipredator training is worthwhile for future reintroduction programs for greater rheas, since their memory capacity is considerable.
