Análise faunística dos helmintos de pardais (Passer domesticus L., 1758) capturados em Campo Grande, Rio de Janeiro, RJ

Sparrows captured in Campo Grande, Rio de Janeiro, RJ, were examined through necropsy and the helmints found were identified. The prevalence, intensity of infection and the habitat of each helminth species found are showed. An analysis of the helminth fauna using the importance value of the species collected indicated that in the sparrow the dominant species are: Leucochloridium parcum, Tanaisia inopina, Choanotaenia passerina, Dispharynx nasuta and Tetrameres minima; and the co-dominant species are: Echinostoma revolutum, Eumegacetes mediximus and Mediorhynchus papillosus. According to the host specificity were classified as specialist species: L. parcum, T. inopina, C. passerina and T. minima; and as generalist species: E. revolutum, E. medioximus, D. nasuta and M. papillosus. Echinostoma revolutum was found for the first time in P. domesticus. The species E. medioximus , T. minima and D. nasuta were found for the first time in the sparrow in Brazil. The species C. passerina and M. papillosus were found for the first time in Brazil, expanding their distribution to the Neotropical region.

The Integrated Traditional United Europe Food Project (TRUEFOOD) aims to improve quality and safety and introduce innovation into Traditional European Food production systems through research, demonstration, dissemination and training activities. The proposed demonstration session offers professionals the opportunity to learn about and discuss the last research results in food technology. The use of new technologies for the selection of raw hams and the design and optimization of new processes to facilitate the achievement of products with a reduced salt content and without sensory defects will be demonstrated.

Notes on the biology of Amblyomma dissimile Kock, 1844 (Acari: Ixodida) on Bufo marinus (Linnaeus, 1758) from Brazil

Amblyomma dissimile is a common ectoparasite of cold blooded animals and is an accidental ectoparasite of some wild mammals. Details of the biology of specimens from the State of Amapá were studied in the laboratory in a humidity chamber at an average environmental temperature of 19.5 °C, using Bufo marinus as host for the time in Brazil. We also report the first record of this species in the State of Minas Gerais.

Neotropical monogenoidea. 25. Anacanthorus penilabiatus n. sp. (Dactylogyridae, Anacanthorinae) from Piaractus mesopotamicus (Osteichthyes, Serrasalmidae), cultivated in the State of São Paulo, Brazil

Anacanthorus penilabiatus n. sp. is described from the serrasalmid fish, Piaractus mesopotamicus (Holmberg, 1887), cultivated in the Centro de Aqüicultura, Universidade Estadual Paulista. The new species is characterized by having a relatively straight copulatory organ with a long "lip" on the distal margin and a median longitudinal flap, and a copulatory ligament. The large size of the infrapopulations of this species of parasite indicates that it should be considered a potential agent causing losses in aquaculture of the fish host.

Synaptobrevin N-terminally bound to syntaxin-SNAP-25 defines the primed vesicle state in regulated exocytosis.

Rapid neurotransmitter release depends on the ability to arrest the SNAP receptor (SNARE)-dependent exocytosis pathway at an intermediate "cocked" state, from which fusion can be triggered by Ca(2+). It is not clear whether this state includes assembly of synaptobrevin (the vesicle membrane SNARE) to the syntaxin-SNAP-25 (target membrane SNAREs) acceptor complex or whether the reaction is arrested upstream of that step. In this study, by a combination of in vitro biophysical measurements and time-resolved exocytosis measurements in adrenal chromaffin cells, we find that mutations of the N-terminal interaction layers of the SNARE bundle inhibit assembly in vitro and vesicle priming in vivo without detectable changes in triggering speed or fusion pore properties. In contrast, mutations in the last C-terminal layer decrease triggering speed and fusion pore duration. Between the two domains, we identify a region exquisitely sensitive to mutation, possibly constituting a switch. Our data are consistent with a model in which the N terminus of the SNARE complex assembles during vesicle priming, followed by Ca(2+)-triggered C-terminal assembly and membrane fusion.

Tratamiento de los hemangiomas infantiles con propranolol: estudio prospectivo abierto con 25 pacientes. Evolución y manejo”

Estudi observacional prospectiu obert sobre l’eficàcia del propranolol oral en 25 nens amb hemangiomes infantils que associen algun tipus de morbiditat. S’analitzen també els efectes secundaris, l’evolució de les lesions i les variables que influeixen en les recaigudes al finalitzar la medicació. L’estudi conclou que el propranolol és un fàrmac efectiu i ben tolerat en el tractament dels hemangiomes infantils. La duració del tractament és la única variable que demostra influir de forma estadísticament significativa en l’aparició de recidives al suspendre la medicació.

Rearing of Lymnaea columella (Say, 1817), intermediate host of Fasciola hepatica (Linnaeus, 1758)

The intermediate host of Fasciola hepatica, Lymnaea columella, collected in Belo Horizonte, Minas Gerais, Brazil, was reared in our laboratory. The aim of the current study was to standardize a rearing and maintenance technique. Two kinds of diet were tested: fresh lettuce (A) and rodent ration + 10% CaCO3 plus fresh lettuce (B). The age for the beginning of oviposition ranged from 27 to 57 days. Ten days after oviposition at 24.7°C, 100% eclosion occurred. The complete life cycle varied from 37 to 67 days. The average numbers of eggs per egg mass were 26.3 and 31.1 with diets (A) and (B), respectively. The lettuce and ration fed snails presented a increased growth although the difference was not statistically significant (p > 0.05). The mortality rate varied from 40 to 64% after 90 days. The maximum longevity was 183 days, 21.5 mm length and 11 mm wide. The methodology to mass breed and maintain these snails was found to be suitable in the laboratory
