Studies on Trypanosoma rangeli Tejera 1920. IV - A reconsideration of its systematic position

The systematic positon of Trypanosoma rangeli is reconsidered and the creation of a new subgenus. Tejeraia, is proposed to remove this trypanosome from the subgenus Herptosoma of the section Stercoraria. The characteristics described for the proposed subgenus indicate that it must be located in the section Salivaria rather than in the Stercoraria. The evidence supporting this proposition is discussed in the text.

Studies on Trypanosoma rangeli Tejera, 1920: V - Developmental pattern in the alimentary canal of Rhodnius prolixus

The morphological sequence of Trypanosoma rangeli development in the alimentary canal of Rhodnius prolixus, is described, with observation made in dissected guts from 6 hours to 45 days post-infection. No metacyclic-forms are produced in the digestive tract at any time, and transmission by the contaminative route must be considered atypical. Amastigotes appear to be an essential stage in the development of T. rangeli in the gut of R. prolixus. The epidemiological importance of the developmental pattern of T. rangeli in the vector´s gut is discussed, and its usefulness for aging infection is considered.

Studies on Trypanosoma rangeli Tejera 1920: VI. Developmental pattern in the haemolymph of Rhodnius prolixus

The morphological sequence of Trypanosoma rangeli development in the body cavity of Rhodnius prolixus is described. The metacyclic trypanosome is the product of successive division and transformation during the intra and extracellular development in the haemocoele. The significance of the early invasion of T. rangeli into the haemolymph is discussed. The epidemiological importance of the developmental pattern of T. rangeli in the vectors haemolymph and the host-response to the parasite are considered.

Studies on Trypanosoma rangeli Tejera 1920. VII - Its effect on the survival of infected triatomine bugs

The pathological effects of Trypanosoma rangeli on Rhodnius prolixus and R. robustus, and the relation of mortality to infection, were studied under laboratory conditions. Frequent observations revealed that when the first instar nymphs of R. prolixus and R. robustus were infected with T. rangeli, survival of the bugs during the stages of development to the adult stage decreased. This decrease was statistically significant when compared with uninfected control-bugs, indicating that T. rangeli is pathogenic for both species of triatomine. In R. prolixus the most affected nymphal stages were the first, second and fifth instars, where a higher mortality was also observed. In R. robustus a progressive increase of the mortality from the first to fifth instars, was observed. The pathogenicity of T. rangeli as measured by overall mortality was the same in R. prolixus and R. robustus. The possible pathogenic mechanism of T. rangeli in triatomine-bugs and its epidemiological implications, are discussed.

Estudios sobre Trypanosoma rangeli Tejera, 1920: VIII. Respuesta a las reinfecciones en dos mamíferos

Bajo condiciones experimentales se estudia el curso de la infección primaria y la respuesta a las reinfecciones por Trypanosoma rangeli en ratones albinos y Didelphis marsupialis. Durante el curso de la infección primaria en ratones, se observa una parasitemia relativamente baja y de corta duración. Los mismos muestran durante la primera reinfección una parasitemia escasa de cuatro días de duración, siendo resistentes a las sucesivas reinfecciones con T. rangeli. Los ejemplares de D. marsupialis exhiben una parasitemia de más larga duración, pero con un nivel de parásitos sanguícolas mucho menor que el detectado en el modelo ratón, siendo la respuesta a las reinfecciones similar a la observada en ratones. Se detectan anticuerpos hemaglutinantes en los sueros inmunes de ratones y Didelphis marsupialis, sometidos a la reinfección por T. rangeli. Se especula sobre la posible acción sinérgica de una respuesta inmune en el sitio de deposición en contra de las formas metacíclicas de T. rangeli y la acción de anticuerpos circulantes en contra de las formas sanguícolas, para explicar la resistencia de ambos modelos a las reinfecciones por T. rangeli.

Violence: les femmes font confiance au milieu médical [Partner violence: women trust health professionals]

In 2008, the department of gynaecology and obstetrics of a university hospital centre implemented a program addressing interpersonal partner violence (screening, prevention and care of the patient victims). A qualitative survey was conducted to identify the needs and feelings of patients. The results show that patients are in favour of being actively and directly questioned about violence during the consultation and that they trust medical doctors and nurses to help and support them.

Studies on Trypanosoma rangeli Tejera, 1920: IX. Course of infection in different stages of Rhodnius prolixus

Frequent individual observations od different stages of Rhodnius prolixus exposed to Trypanosoma rangeli, revealed a higher susceptibility to infection in the bugs exposed during the two first instars. The mortality rate in infected bugs was significantly higher than in controls, indicating that the parasite was responsible for the majority of deaths. An analysis of the mortality distribution, per instar, is presented. Statistical analysis of deaths among the different infected instars, showed that T. rangeli produces its pathological effect in any stage of R. prolixus independently of its susceptibility to the parasite. The survival to adult decreased in all the infected instar bugs. A significant longer time to reach the adult stage was observed in the infected bugs when compared with controls, excepting for specimens exposed in the third instar. The epidemiological significance of the present results is discussed.

Descriptions of syntypes of Brumptamyia brumpti (Lsrrousse, 1920) (Diptera: Psychodidae-Phlebotominae)

The male and female of Brumptomyia brumpti (Larrousse, 1920), the type species of the genus Brumptomyia França & Parrot, 1921 (Diptera: Psychodidae - phlebotominae) are redescribed from syntypes in the British Museum (Natural History).

The Core ideas and axioms of classical fascism (1919-1945)

This article presents and explores the axioms and core ideas, or idées-force, of the Fascist ideologies of the first third of the twentieth century. The aim is to identify the features that define the term “Classical Fascism” as a conceptual category in the study of politics and to uncover the core ideas of its political theory. This analysis requires an appraisal of both the idées-force themselves and the political use that is made of them. If these appreciations are correct, Classical Fascism is characterized by a set of ideological and political aims and methods in which ideas, attitudes and behaviours are determined by an anti-democratic palingenetic ultranationalism underpinned by a sacralized ideology; the quest for a united, indissoluble society as apolitical system and, at the same time, the collective myth that mobilizes and redeems the nation; and third, violence as a political vehicle applied unchecked against internal opposition and against external enemies who challenge the nation´s progression towards the dream of rebirth and the culmination of this progression in the form of an empire.

Sapromyza lopesi sp. n. from Brazil: a species related to S. duodecimvittata (Frey, 1919) (Diptera: Lauxaniidae)

A new species, Sapromyza lopesi, is described from Brazil, and compared with its closest relative, S. duodecimvittata (Frey). Some remarks are made on the generic classification of South American Lauxaniidae as it affects these and other species.
