During a survey of the helminth parasites of the introduced load, Bufo marinus, on O'ahu, Hawaii, an acanthocephalan corresponding to Acanthocephalus bufonis (Shipley, 1903) was found in the intestinal tract. This is a new host and locality record for A. bufonis which has only previously been recorded from amphibians in the Orient. Possible mechanisms for the introduction of A. bufonis to Hawaii, and its transmission to the toad, are discussed. Almost 98 % of toads were infected with a mean intensify of: 28.6 acanthocephalans per infected toed. There was a significant negative correlation between host length and intensity of infection with subadult toads having significantly higher infection levels than adult male and female loads. Trunk length of both male and female acanthocephalans was significantly related to host length.

Heterosentis hirsutus n. sp. is described from Cnidoglanis macrocephalo (Siluriformes: Plotosidae) from the Swan Estuary, Western Australia. It is distinguished by having 14 longitudinal rows of 6-7 hooks per row on the proboscis, a trunk armed anteriorly and posteriorly (=genital spines) with minute spines and lemnisci that may extend to the poster;or margin of the proboscis receptacle The new species also has prominent fragmented nuclei in its trunk well. New information is given for Heterosentis plotosi Yamoguti, 1935 from Plotosus lineatus (Siluriformes: Plotosidae) and H. poraplagusiarum (Nickol, 1972) Amin, 1985 from Paraplogusia guttata (Pleuronectiformes: Cynoglossidoe), both from Queensland. A key to the species of Heterosentis Van Cleave, 1931 is provided. The Arhythmacanthidae subfamilies are reviewed: there is little utility in the recognition of these taxa because of the small number of genera involved and the validity/ of the characters on which they ore based is in doubt, particularly whether trunk spines are present or absent. Only Acanthocephaloides Meyer, 1932, Breizocanthus Golvon, 1969, Euzetocanthus Golvan & Houin, 1964, Heterosentis, Hypoechinorhynchus Yamaguti, 1939 and Paracanthocepholoides Golvan, 1969 of the Arhythmacanthidae are considered valid. A key to these genera is provided. The monotypic genus Neocanthocepholoides Cable & Quick, 1954 is considered a new synonym of Acanthocephaloides thus creating Acanthocephaloides spinicaudatus (Cable & Quick, 1954) n. comb. Arhythmocanthus Yamaguti, 1935 is maintained as a synonym of Heterosentis because the distinction between two and three hook types is made equivocal when the transition between the opical and subapical hooks is gradual.

An 18-year-old boy with refractory epilepsy and aggressiveness associated to a hypothalamic hamartoma was submitted to a stereotactically guided lesion by thermocoagulation. The target was based on magnetic resonance (MR) images merged with computed tomography scan images taken on the day of surgery while patient was on a stereotactic frame. In order to reveal structures not discernible in MR images, the Schaltenbrand digital brain atlas was merged onto the patient`s images. Target and trajectory of the depth electrode were chosen based on three-dimensional imaging reconstructions. A surgical plan was devised to disconnect the hypothalamic hamartoma from the hypothalamus, medial forebrain bundle, fasciculus princeps, and dorsal longitudinal fasciculus. Our target was placed at the inferior portion of the posterolateral component of the hamartoma, bordering the normal hypothalamus. The patient evolved with marked lessening of aggressiveness. Seizure frequency was reduced from several seizures per day to less than one tonic-clonic seizure during sleep per month and only two episodes suggestive of partial complex seizures during daytime. These results have remained consistent over a 24-month postoperative follow-up. Functional neuroanatomy of hypothalamic connections involved in seizure propagation and aggressive behavior was reviewed.

A rapid DNA extraction was used for T. cruzi detection in triatomines dry fecal spots collected on filter paper and analyzed by PCR. Fifty T infestans were fed on experimentally infected Balb/C mice with high T. cruzi parasitemia and divided into five groups of len triatomines, and 100 triatomines were infected with lower parasitemia and divided into five groups of 20 triatomines, One dry fecal spot was analyzed per group on days 1, 2, 3, 4 and 5 post feeding. Amplification targeted T. cruzi TCZ sequence and resulted positive from day 4 after bugs feeding in the two models (high and lower parasitemia). The rapid DNA isolation and PCR proposed are suitable for detection of T. cruzi DNA in in filter paper and should be considered in field research.

O entendimento dos fenômenos de trocas de carbono entre solo, água e atmosfera é fundamental para o manejo e a conservação de ecossistemas naturais e agrários. Os objetivos deste trabalho foram determinar os estoques de carbono orgânico, as suas frações e a fertilidade do solo sob os manejos florestal (mata remanescente), integrando agricultura e florestas (eucalipto e cutieira) e em monoculturas agrícola (sob pivô central) e pastoril (braquiária), na Bacia do Rio Paraopeba, em Florestal-MG, visando a propor indicadores para a avaliação de manejo e conservação do solo. As amostras de solo foram coletadas em remanescente de mata nativa (Mata), em área agrícola cultivada sob irrigação de pivô central (Pivô) e em áreas de cultivo de Corymbia citriodora (Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson) (Eucalipto), Joannesia princeps Vell. (Cutieira) e Brachiaria decumbens Stapf (Pasto), nas profundidades de 0 a 20 e 20 a 40 cm. Os resultados indicaram que as estimativas dos estoques e de estabilidade do carbono orgânico aumentaram com a fertilidade do solo. Os sistemas florestais, principalmente a Mata, acompanhada pelos sistemas de manejo do solo integrando florestas à pastagem, em comparação com o cultivo contínuo ou a monocultura de pastagem, apresentaram estoques de carbono maiores, mais estáveis e menos solúveis, com formas mais aromáticas e hidrofóbicas (maior relação AH/AF), indicando menor potencial de lixiviação de carbono para o sistema aquático adjacente.

A primeira edição portuguesa d' O Príncipe , de Maquiavel, viu a luz em 1935, mais de quatrocentos anos após a publicação original italiana. Apareceu sob a forma de “edição política”, que, naquela precisadata apresentava ao leitor português um Maquiavel fascista, prefaciado pelo próprio Mussolini. Em que conjuntura política e ideológica se inscreveu a edição? Como se apresenta e que sentido teve a apropriação ideológica de Maquiavel? Que méritos tem a tradução? Quem foi Francisco Morais, o organizador, tradutor e anotador da princeps portuguesa? E, finalmente, que futuro teve esta, em Portugal? Eis algumas das questões a que este texto procura dar resposta.
