Souza, Christiane Sampaio de;Mafalda Júnior, Paulo;
Brazilian Archives of Biology and Technology , 2008, DOI: 10.1590/S1516-89132008000600023
Abstract: this work had as objective to study the distribution and abundance of the carangidae larvae and to analyze the influence of the hydrological (temperature and salinity) and biological factors (phytoplanktonic biomass and zooplanktonic biomass), on the space and temporal distribution of the larvae. ichthyoplankton was collected during four expeditions from the northeast exclusive economic zone. six species (trachurus lathami, decapterus punctatus, chloroscombrus chrysurus, selene setapinnis, selene vomer and elagatis bipinnulata) and caranx- carangoides complex were identified. d. punctatus was the species most abundant (52% of the total), with higher abundance during the period 3, while the period 2 was the period of low abundance. c. chrysurus was the second species in abundance representing 30% of the total of carangid. this species had higher abundance during the period 2 and the period 1. however, in period 3 abundance were lesser. the third species in abundance was t. lathami that corresponded 8% of the total of carangid larvae. s. setapinnis, s. vomer and e. bipinnulata were the species less abundant, representing together 2% of the total identified larvae. the larvae of caranx- carangoides complex represented 9% of the carangid total.
Participa??o social em saúde em áreas rurais do Nordeste do Brasil
Bispo Júnior,José Patrício; Sampaio,José Jackson Coelho;
Revista Panamericana de Salud Pública , 2008, DOI: 10.1590/S1020-49892008000600005
Abstract: objectives: to analyze the social participation taking place through municipal health councils (mhc) in two small towns in northeastern brazil. methods: a qualitative, exploratory, multicase study focused on the mhcs of lafayete coutinho (state of bahia) and groaíras (state of ceará) was conducted. data were gathered from february-april 2005 through analysis of documents, direct observation of mhc meetings, and semistructured interviews. documents analyzed included decrees, laws, and municipal regulations; city health department annual management reports; municipal health plans; and reports of municipal health conferences. mhc meeting minutes for the period between inception of these councils and 2004 were also reviewed. interviews of 17 council members took place, eight of whom were from lafayete coutinho and nine from groaíras. results: both councils had irregular practices regarding membership structure and nomination of members, such as frequent changes in appointed members and continuous "reshuffling" of council structure. in addition, new council members were appointed each time a new mayor took charge. sporadic frequency of meetings was also observed. in lafayete coutinho, of 96 meetings planned, just 37 took place; in groaíras, of 186 meetings planned, 93 took place. analysis of mhc efforts to formulate and control municipal health policies revealed three themes: health status of the population and public policies; organization and functioning of health services; and financial management and accounting. the interviews showed that council members were dissatisfied with the practices of the mhcs and revealed a lack of confidence in how truly representative the councils are and how much power they have. conclusions: social participation strategies in brazil must be reconsidered with an angle toward promoting political responsibility and raising awareness among citizens.
Composition of Trichiuridae and Gempylidae larvae (Teleostei) and their association with water masses in the Southwest Atlantic Ocean

Abstract: In this paper the relationship between temporal changes in the occurrence of water masses and Trichiuridae and Gempylidae larvae composition and distribution in the Southwest Atlantic ocean were analysed between 25° and 40° S. Ichthyoplankton was collected during the three expeditions of the Subtropical Convergence Project: Winter and Spring 1977, Autumn 1978 and Summer 1981, realized in the Southwest Atlantic waters. Oblique tows were conducted using a Hensen net with 250 μm mesh size. Steep salinity and temperature gradient were found, where the river outflows from La Plata river (Argentina) and Patos Lagoon (Brazil) met the Tropical Water over the continental shelf between 32 and 36° S. We examined 524 Hensen-net samples that contained about 283 larvae from five species of Trichiuridae and Gempylidae. The most abundant and frequent specie were Trichiurus lepturus Linnaeus 1758 and Diplospinus multistriatus Maul 1948. The mesopelagics species D. multistriatus, Nealotus tripes Johnson 1865 and Lepidopus altifrons Parin&Collette, 1993 were associated with Tropical Water. The benthopelagic T. lepturus and the epipelagic Thyrsitops lepidopoides (Cuvier 1832) were associated mainly with Coastal Water and Subtropical Shelf Water.

DNA identification of Leishmania (Viannia) braziliensis in human saliva from a patient with American cutaneous leishmaniasis
Corvalan, FH;Sampaio, RNR;Brustoloni, YM;Andreotti, R;Lima Júnior, MSC;
Journal of Venomous Animals and Toxins including Tropical Diseases , 2011, DOI: 10.1590/S1678-91992011000100013
Abstract: this study aims to report the amplification of the dna of leishmania (v.) braziliensis, using polymerase chain reaction, obtained from the saliva of a patient with american cutaneous leishmaniasis who did not present any lesion in the oral mucosa. amplification produced fragments of 103 bp, an estimated size employing leishmania (v.) braziliensis primers (b1 e b2). the present results revealed, for the first time, that the in vitro amplification of leishmania dna using samples from the salivary fluid of a patient with american cutaneous leishmaniasis is possible. however, more studies are required with a larger number of participants to evaluate the usefulness of saliva as a non-invasive sample for pcr. the development of such non-invasive technique is necessary for the diagnosis of many diseases in the future, especially infectious and parasitic ones.
In vitro evaluation of the effect of natural orange juices on dentin morphology

Abstract: the patient's diet has been considered an important etiological factor of dentin hypersensitivity. the frequent ingestion of acidic substances can promote the loss of dental structure or remove the smear layer. the purpose of this study was to evaluate the degree of smear layer removal and dentinal tubules exposure by different natural orange juices. extracted human teeth were submitted to manual scaling in order to develop the smear layer. seventy dentin samples were obtained and distributed into the following groups: control, lime orange, lime, valência orange, navel orange, mandarin, and tangerine. each group included 2 methods of application: topical and topical + friction. after preparation for sem analysis, photomicrographs were assessed by a blind calibrated examiner using an index system. the kruskal-wallis test indicated a significant influence of the orange juices on smear layer removal. significant difference was observed between navel orange, valência orange, mandarin and the control group (p < 0.05). these orange juices resulted in greater removal of the smear layer and greater opening of dentinal tubules. the comparison between the application methods for each group using the mann-whitney test showed that friction increased smear layer removal significantly only for lime orange and lime. the data suggest that certain natural orange juices are more effective in terms of smear layer removal and dentinal tubules exposure than others.

Abstract: dentin hypersensitivity is a common painful condition observed in clinics. dietary habits have been much associated with its development and persistence during and following periodontal treatment. the aim of this in vitro study was to evaluate the influence of vinegars on the removal of smear layer and exposure of dentinal tubules. extracted human teeth were submitted to manual scaling with gracey curettes in order to remove the cementum as well as to form a smear layer. dentin samples with 3 mm2 were obtained and distributed into six experimental groups: one control and five types of vinegars (alcohol, apple, rice, white wine and balsamic). each group included two methods of vinegar application: topical and friction. after routine preparation for sem analysis, photomicrographs were assessed by a calibrated and blind examiner using an appropriate index system. kruskal-wallis test indicated a significant influence of vinegars on smear layer removal. there was a statistically significant difference between groups treated with apple, white and rice vinegars and the control group (p < 0.05). nevertheless, mann-whitney test indicated that removal of smear layer did not vary with the method of application (topical versus friction) for any of the tested substances. we can conclude that the contact of vinegar may remove smear layer and expose dentinal tubules, regardless of the type of application. however, balsamic vinegar was associated with less removal of smear layer after both methods of application.
