Avaliação normativa das salas de vacinas na rede pública de Saúde do municipio de Marilia, Estado de São Paulo, Brasil 2008 -2009.

Objective: to evaluate the standardization of vaccination rooms in the Municipality of Marília, State of São Paulo, Brazil. Methods: descriptive and exploratory study, realized in 2008-2009; the instrument used was the Supervision in Vaccination Rooms, of the Ministry of Health; variables analyzed were general aspects of the vaccination room, technical procedures, cold chain, information system, post-vaccination adverse events, special immunobiologicals, epidemiological surveillance and health education; the score achieved classifies the room (90.0-100.0% = ideal; 76.0-89.0% = good; 50.0-75.0% = fair; <50.0% = insufficient); overall index for each point was calculated as the average score of all rooms. Results: technical procedures, information system, post-vaccination adverse events and special immunobiologicals were scored as ideal; cold chain, epidemiological surveillance and health education were scored as good; and to general aspects of the vaccination room, the evaluation was fair. Conclusion: general index for vaccination rooms in the municipality was considered ideal.

A field study to describe diel, tidal and semilunar rhythms of larval release in an assemblage of tropical rocky shore crabs

Available information on the larval release rhythms of brachyurans is biased to temperate estuarine species and outcomes resulting from some sort of artificial manipulation of ovigerous females. In this study we applied field methods to describe the larval release rhythms of an assemblage of tropical rocky shore crabs. Sampling the broods of ovigerous females of Pachygrapsus transversus at two different shores indicated a spatially consistent semilunar pattern, with larval release maxima around the full and new moon. Yet, synchronism between populations varied considerably, with the pattern obtained at the site exposed to a lower wave action far more apparent. Breeding cohorts at one of the sampled shores apparently belonged to actual age groups composing the ovigerous population. The data suggest that these breeding groups release their larvae in alternate syzygy periods, responding to a lunar cycle instead of the semilunar pattern observed for the whole population. For the description of shorter-term rhythms, temporal series at hour intervals were obtained by sampling the plankton and confinement boxes where ovigerous females were held. Unexpectedly, diurnal release activity prevailed over nocturnal hatching. Yet, only grapsids living higher on the shore exhibited strong preferences over the diel cycle, with P. transversus releasing their larvae during the day and Geograpsus lividus during the night. The pea crab Dissodactylus crinitichelis, the spider crab Epialtus brasiliensis and a suite of xanthoids undertook considerable releasing activity in both periods. Apart from the commensal pea crab D. crinitichelis, all other taxa revealed tide-related rhythms of larval release, with average estimates of the time of maximum hatching always around the time of high tides; usually during the flooding and slack, rather than the ebbing tide. Data obtained for P. transversus females held in confinement boxes indicated that early larval release is mostly due to nocturnal hatching, while zoeal release in diurnal groups took place at the time of high tide. Since nocturnal high tides at the study area occurred late, sometimes close to dusk, early release would allow more time for offshore transport of larvae when the action of potential predators is reduced.

O setor pesqueiro em Portugal - relato de caso

Interviews were conducted with scientific researchers and process industries, bibliographic research and observational technical visits to collect information about the portuguese fishery sector. The relevance of this sector derives essentially from the fact that fish is a key component of food and responsible for large number of jobs within the Portuguese population. With the reduction in catches due to the decline in world's fish stocks the government has encouraged actions of ecological nature to promote the sector sustainability. Actually, the decline in the market expression facilitates the entry of stranger companies from others countries. Entrepreneurs must increase the productivity and provide quality assured products in order to achieve the export market.

Distribuição espacial de Huanglongbing (Greening) em citros utilizando a geoestatística

Os objetivos do trabalho foram avaliar a distribuição espacial e a expansão da Huanglongbing (greening) em talhões de citros de uma propriedade agrícola localizada no município de Araraquara-SP, utilizando a geoestatística. Para determinar o número de plantas com greening, foram realizadas inspeções periódicas em intervalos de três meses, no período de março de 2005 a julho de 2007, contando-se, em cada talhão, o número de plantas com os sintomas característicos da doença. Realizou-se a análise descritiva dos dados e, para verificar a distribuição espacial do greening, utilizou-se a geoestatística através do ajuste de semivariogramas e da interpolação dos dados por krigagem. A dependência espacial de plantas com greening apresentou raio de agregação de 300 a 560 m, indicando distribuição agregada da doença. Por meio dos mapas de krigagem, observou-se que o foco inicial de plantas doentes ocorreu nos limites da fazenda, com expansão do greening por toda a área. O intervalo de inspeção de três meses não foi adequado para a redução do greening na fazenda.

O amor pode ser virtual? O relacionamento amoroso pela Internet

Este estudo teve como finalidade contribuir para o entendimento de uma nova modalidade de relacionamento - o virtual. Dele participaram 50 usuários brasileiros da Internet, que responderam a um questionário contendo 31 questões sobre opiniões e comportamentos relacionados a afetividade e relacionamento virtual. A amostra foi composta, em sua maior parte, por homens, adultos jovens, solteiros, sem filhos, dos níveis socioeconômicos médio e alto. Verificou-se que os sujeitos acreditam na possibilidade de relacionamentos virtuais em uma fase inicial, no entanto relataram necessidade do contato face a face para sua continuidade. Observou-se também alta freqüência de usuários de chats de conversação considerados viciados na Internet. A partir dos resultados obtidos, concluiu-se que não houve mudanças comportamentais e afetivas radicais com essa nova forma de relacionamento, mas os dados sugerem a importância de mais pesquisas para esclarecer as conseqüências do relacionamento virtual e do uso exagerado da Internet como forma de comunicação social.

The oxidation of apocynin catalyzed by myeloperoxidase: Proposal for NADPH oxidase inhibition

Apocynin has been used as an efficient inhibitor of the NADPH oxidase complex and its mechanism of inhibition is linked to prior activation through the action of peroxidascs. Here we studied the oxidation of apocynin catalyzed by myeloperoxidase (MPO) and activated neutrophils. We found that apocynin is easily oxidized by MPO/H2O2 or activated neutrophils and has as products dimer and trimer derivatives. Since apocynin impedes the migration of the cytosolic component p47phox to the membrane and this effect could be related to its conjugation with essential thiol groups, we studied the reactivity of apocynin and its MPO-catalyzed oxidation products with glutathione (GSH). We found that apocynin and its oxidation products do not react with GSH. However, this thiol compound was efficiently oxidized by the apocynin radical during the MPO-catalyzed oxidation. We suggest that the reactivity of apocynin radical with thiol compounds could be involved in the inhibitory effect of this methoxy-catechol on NADPH oxidase complex. (c) 2006 Elsevier B.V.

The reactivity of oytho-methoxy-substituted catechol radicals with sulfhydryl groups: Contribution for the comprehension of the mechanism of inhibition of NADPH oxidase by apocynin

Redox processes are involved in the mechanism of action of NADPH oxidase inhibitors such as diphenyleneiodonium and apocynin. Here, we studied the structure-activity relationship for apocynin and analogous ortho-methoxy-substituted catechols as inhibitors of the NADPH oxidase in neutrophils and their reactivity with peroxidase. Aiming to alter the reduction potential, the ortho-methoxy-catechol moiety was kept constant and the substituents at para position related to the hydroxyl group were varied. Two series of compounds were employed: methoxy-catechols bearing electron-withdrawing groups (MC-W) such as apocynin, vanillin, 4-nitroguaiacol, 4-cyanoguaiacol, and methoxy-catechol bearing electron-donating groups (MC-D) such as 4-methylguaiacol and 4-ethylguaiacol. We found that MC-D were weaker inhibitors compared to MD-W. Furthermore, the radicals generated by oxidation of MC-W via MPO/H(2)O(2), but not for MC-D, were able to oxidize glutathione (GSH) as verified by the formation of thiyl radicals, depletion of GSH, and recycling of the ortho-methoxy-catechols during their oxidations. The capacity of oxidizing sulfhydryl (SH) groups was also verified when ovalbumin was incubated with MC-W, but not for MC-D. Since the effect of apocynin has been correlated with inactivation of the cytosolic fractions of the NADPH oxidase complex and its oxidation during the inhibitory process develops a special role in this process, we suggest that the close relationship between the reactivity of the radicals of MC-W compounds with thiol groups and their efficacy as NADPH oxidase inhibitor could be the chemical pathway behind the mechanism of action of apocynin and should be taken into account in the design of new and specific NADPH oxidase inhibitors.

Chemiluminescent determination of leukocyte alkaline phosphatase: An advantageous alternative to the cytochemical assay

The determination of leukocyte alkaline phosphatasd (LAP) is used as an aid to diagnose many diseases in the laboratory. For example, it can be used to distinguish chronic myeloid leukemia (CML) from other myeloproliferative disorders (particularly myelofibrosis and polycythemia) and leukemoid reactions (LR). Traditionally, this test is performed with the use of subjective cytochemical assays that assign a score to the level of LAP. Here we present a nonsubjective, quantitative, sensitive, and inexpensive chemiluminescent technique that determines LAP based on the commercial reagent Immulite (R) (AMPPD). To validate this methodology, intact leukocytes obtained from 32 healthy subjects, nine CML patients, and nine LR patients were submitted to the optimized protocol. By measuring the light emission elicited by four concentrations of neutrophils, we were able to estimate the activity of LAP per cell (the slope of the curve obtained by linear regression). A high linear correlation was found between the chemiluminescent result (slope) and the cytochemical score. The slope for healthy individuals ranged between 0.61 and 8.49 (10(-5) mV.s/cell), with a median of 2.04 (10(-5) mV.s/cell). These results were statistically different from those of CML patients (range = 0.07-1.75, median = 0.79) and LR patients (range = 3.84-47.24, median 9.58; P < 0.05).
