A review is made of the evidence indicating the existence of gene amplification in Rhynchosciara, from the early cytological work to the more recent studies using cloned sequences from the DNA puffs. Mention is made of work still in progress which indicates that the transcription unit of a DNA puff is surprisingly complex.

Mazocraeoides georgei price, 1936 and mazocraeoides opisthonema Hargis, 1955 are reported for the first time in Brazil in Brevoortia aurea (Spix, 1829) and in Harengula clupeola (Cuvier, 1829) respectively, clupeid fishes from the littoral of Rio de janeiro State, which represent new host records. Mazocraeoides olentangiensis Sroufe, 1958 and mazocraeoides hargisi Price, 1961 are considered new synonyms for Mazocraeoides georgei.

This paper describes some results of a systematic survey of the Ceratopogonidae midges of the State of Minas Gerais, Brazil. Three species, Stilobezzia punctulata Lane, 1947, Heteromyia chaquensis Duret & Lane, 1955 and Dasyhelea paulistana Forattini & Rabello, 1957 were identified from a small lake, "Lagoinha" or "Olhos d'Água", near to the main lake of Lagoa Santa. The first descriptions of the males of Heteromyia chaquensis and Dasyhelea paulistana are presented.

The authors present the list of the species caught in the National Parks of Ubajara and Sete Cidades, in the counties of Ubajara (CE) and Piracuruca (PI), respectively, and described the Lutzomyia (Helcocyrtomyia) samueli (Deane, 1955) female, which up to now had been known by the male.

Ultrastructural aspects of spermatogenesis, spermiogenesis and of the mature spermatozoon of a microcotylid monogenean Metamicrocotyla macracantha parasite from Mugil liza, are described. The irregularly-shaped spermatogonia divides by successive mitoses, forming the primary spermatocytes, identified by the presence of synaptonemal complexes in their nuclei. The spermatids formed by meiotic cell divisions of the secondary spermatocytes, differentiate into a mature spermatozoon. Cross sections of the head and the middle region of mature spermatozoa show the nucleus with strong condensed chromatin, the mitochondria with short cristae, peripheral microtubules and two axonemes with a 9+1 pattern, confirming the characteristics of this genus.

The following new species are described in the subgenus Bisaltes (Bisaltes): B. (B.) picticornis sp. nov. from Bolivia; B.(B.) taua sp. nov. from Brazil (Paraná and Santa Catarina) and B. (B.) unicolor sp. nov. from Ecuador. Bisaltes (B.) pictus Breuning, 1940 is transferred to the subgenus Craspedocerus. In Ptericoptus, P. hybridus hybridus Breuning, 1939 is considered a synonym of P. acuminatus (Fabricius, 1801); P. dorsalis Audinet-Serville, 1835 previously in the synonymy of P. acuminatus is revalidated and Saperda vitta Newman, 1838 is considered its synonym; P. corumbaensis sp. nov. is described from Brazil (Mato Grosso do Sul).

ABSTRACT Moncini is the tribe of Hesperiidae that comprises the greatest diversity of small, brown, hard to identify skippers. The group is peculiarly classified as having many monotypic genera, thus offering low informative value to its systematics. This study presents a review of the genus Gallio Evans, 1955, a genus formerly recognized as monotypic, and describes three new species, Gallio imperatriz sp. nov. from Maranhão, Brazil, Gallio furtadoi sp. nov. from Mato Grosso, Brazil and Gallio eti sp. nov. from Madre de Díos, Peru and Acre, Brazil (type locality). A lectotype for Vehilius carasta Schaus, 1902 is designated. Gallio is therefore redescribed and illustrations and diagnosis to its species are provided.

Considerada ponto de convergência entre uma medicina mais mística e uma medicina mais objetiva, a Anatomia e a dissecação traçam uma trajetória sócio-histórica de proximidade com a profissão médica, constituindo parte da racionalidade profissional, justificando-se sua constância nos currículos médicos pela imprescindibilidade de conhecer o corpo-máquina humano para a plena execução das atividades profissionais. Esta dissertação visa caracterizar a Anatomia Humana como disciplina no contexto da Faculdade de Medicina da Universidade de São Paulo no período de cátedra de Renato Locchi (19371955). Propõe-se a distinguir as características iniciais da constituição da Anatomia Humana enquanto disciplina nesta instituição; determinar seu espaço de legitimidade curricular; estabelecer seus elementos constitutivos diante da documentação analisada; e discutir possíveis permanências e rupturas na disciplina empreendida por Renato Locchi. Utilizamos como base as teorias da construção sócio-histórica das disciplinas escolares, notadamente as discussões de André Chervel e Ivor Goodson, de onde elencamos os elementos constitutivos de uma disciplina, categorias que utilizamos como base para a análise da documentação resgatada nos acervos do Museu de Anatomia Humana "Alfonso Bovero" do ICB/USP, do Museu Histórico "Carlos da Silva Lacaz" e da Assessoria Técnica Acadêmica, ambos da FMUSP. Tendo como base a análise de fontes primárias, traçamos uma disciplina com forte retórica legitimadora empreendida por Renato Locchi, que distingue o espaço-tempo da cadeira em duas vertentes: a anatomia como campo de pesquisa e a anatomia escolar, esta composta por seleções históricas mediadas pela primeira. Aliado às suas ações de ocupação dos espaços institucionais e modificações na cátedra que consolidaram espaços e tempos para as disputas internas oriundas das subculturas disciplinares emergentes, organizando os saberes e indivíduos em uma comunidade representativa, reforçando e criando tradições, elevando ao ápice o paradigma dissecatório como método, atividade e avaliação, Renato Locchi constrói a disciplina de Anatomia na acepção estrita do conceito.

Brazil (1955-2005): 25 years of catching-up, 25 years of falling behind. The present paper discusses the Brazilian industrial development under a neo-schumpeterian perspective in the period after 1955. The hypothesis is that, in the last 50 years, Brazil spent the first 25 years catching up and, next, the following 25 years falling behind. The 1955-1980 period, by means of international funding, allowed catching up with the paradigm in maturation within the fourth technological revolution. However, in this period, it was determined the main debilitating elements for the country's entrance in the new techno-economical paradigm of the fifth technological revolution which emerged in the middle of the 70s. It is in the strategy to internationalize the economy, granting the mutinational companies the key-sectors of the national economy dynamics during the catching up period, the main element of dependence in the journey that conditions the current performance, responsible for technology subordination and keeps the Brazilian economy with low dynamism.
