    Full Text Available Abstract Background Adiponectin and resistin are adipokines which modulate insulin action, energy, glucose and lipid homeostasis. Meta-analyses showed that hypoadiponectinemia and hyperresistinemia are strongly associated with increased risk of insulin resistance, type 2 diabetes (T2DM, metabolic syndrome (MS and cardiovascular disease. The aim of this study was to propose a novel adiponectin-resistin (AR index by taking into account both adiponectin and resistin levels to povide a better indicator of the metabolic homeostasis and metabolic disorders. In addition, a novel insulin resistance (IRAR index was proposed by integration of the AR index into an existing insulin resistance index to provide an improved diagnostic biomarker of insulin sensitivity. Methods In this case control study, anthropometric clinical and metabolic parameters including fasting serum total adiponectin and resistin levels were determined in 809 Malaysian men (208 controls, 174 MS without T2DM, 171 T2DM without MS, 256 T2DM with MS whose ages ranged between 40-70 years old. Significant differences in continuous variables among subject groups were confirmed by ANCOVA or MANCOVA test using 1,000 stratified bootstrap samples with bias corrected and accelerated (BCa 95% CI. Spearman's rho rank correlation test was used to test the correlation between two variables. Results The AR index was formulated as 1+log10(R0-log10(A0. The AR index was more strongly associated with increased risk of T2DM and MS than hypoadiponectinemia and hyperresistinemia alone. The AR index was more strongly correlated with the insulin resistance indexes and key metabolic endpoints of T2DM and MS than adiponectin and resistin levels alone. The AR index was also correlated with a higher number of MS components than adiponectin and resistin levels alone. The IRAR index was formulated as log10(I0G0+log10(I0G0log10(R0/A0. The normal reference range of the IRAR index for insulin sensitive individuals was

  2. PCR-based karyotyping of Anopheles gambiae inversion 2Rj identifies the BAMAKO chromosomal form

    Full Text Available Abstract Background The malaria vector Anopheles gambiae is polymorphic for chromosomal inversions on the right arm of chromosome 2 that segregate nonrandomly between assortatively mating populations in West Africa. One such inversion, 2Rj, is associated with the BAMAKO chromosomal form endemic to southern Mali and northern Guinea Conakry near the Niger River. Although it exploits a unique ecology and both molecular and chromosomal data suggest reduced gene flow between BAMAKO and other A. gambiae populations, no molecular markers exist to identify this form. Methods To facilitate study of the BAMAKO form, a PCR assay for molecular karyotyping of 2Rj was developed based on sequences at the breakpoint junctions. The assay was extensively validated using more than 700 field specimens whose karyotypes were determined in parallel by cytogenetic and molecular methods. As inversion 2Rj also occurs in SAVANNA populations outside the geographic range of BAMAKO, samples were tested from Senegal, Cameroon and western Guinea Conakry as well as from Mali. Results In southern Mali, where 2Rj polymorphism in SAVANNA populations was very low and most of the 2Rj homozygotes were found in BAMAKO karyotypes, the molecular and cytogenetic methods were almost perfectly congruent. Elsewhere agreement between the methods was much poorer, as the molecular assay frequently misclassified 2Rj heterozygotes as 2R+j standard homozygotes. Conclusion Molecular karyotyping of 2Rj is robust and accurate on 2R+j standard and 2Rj inverted homozygotes. Therefore, the proposed approach overcomes the lack of a rapid tool for identifying the BAMAKO form across developmental stages and sexes, and opens new perspectives for the study of BAMAKO ecology and behaviour. On the other hand, the method should not be applied for molecular karyotyping of j-carriers within the SAVANNA chromosomal form.

    The pRJ5, a naturally occurring constitutive macrolide, lincosamide and streptogramin B (MLS) resistance plasmid of Staphylococcus aureus, was compared to pE194, a plasmid that confers the inducible phenotype. pRJ5 was stable in all strains of S. aureus tested, even under growth at 43 O C, which distinguished it from pE194 which was shown to be thermo-sensitive for replication. pRJ5, like pE194, was highly unstable in Bacillus subtilis when the cells were grown in nonselective conditions. Multimeric forms of pRJ5 DNA were detected in the few cells of B. subtilis that retained this plasmid. pE194 was transduced by phages φ 11 and φ 443 at frequencies 400 and 20-fold higher, respectively, than pRJ5. Both plasmids were co-transduced with the plasmid pRJ4. pRJ5 was shown to be compatible with pE194. Therefore they belong to distinct Inc groups. Hybridization studies revealed that pRJ5 shares a 1.35 kb region of homology to pE194, which is limited to the erm gene, conferring MLS resistance. (author)

  7. Where Do Dead Books Go? The Problem of the Soviet Canon Today, on the Example of Johannes Becher's Work in Estonian

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The article describes the conception and editing process of an anthology of Johannes Becher’s poems (Unistades täiusest, 1962 in Estonian, and discusses its status in the Soviet and contemporary literary canon. The work on the Becher anthology was led by an already outstanding literary scholar Nigol Andresen and a young poet and translator Ain Kaalep, who later became one of the most prolific and wellknown poetry translators in Estonia. An important part was also played by another poet-translator, August Sang, who already had achieved such a standing in the Estonian literary field. Several other translators contributed to the anthology, making it a common project for intellectuals otherwise very differently positioned vis-à-vis the Soviet political authorities and cultural agendas. Becher’s work was strongly promoted by these instances, but his poetry was also read with genuine enthusiasm by the main contributors to the anthology (whose own poetry has certain parallels to some aspects of Becher’s, as well as the general public, at that time. After the fall of the Soviet regime it has been forgotten, mostly for the same contextual reasons that once granted its success. The case of his poetry in Estonian explores the question of this new invisibility of now politically irrelevant, but still voluminous and aesthetically intriguing literary works in the post-Soviet canon.

Departamento de Medicina e Cirurgia Veterinária, Universidade Federal Rural do Rio de Janeiro, BR 465 Km 7, Seropédica, RJ 23851-900, Brasil. E-mail: marquesapl@ufrrj.br We studied levels and nutrient availability in the soil and grazing of cattle in Middle Paraíba, RJ, Brazil in the early dry season (May-June and rainy (November-December in seven cattle herds with a history of clinical deficiencies of Na, Cu, Co and P, identified through visits to farmers. The mineral contents in the samples were determined by atomic absorption spectrophotometry and values obtained were compared with clinical signs found. Low values of P and Na were confirmed and although the lack of Ca and Mg is uncommon, some samples showed low rates. We found high values of Fe with possible interference in the absorption of Cu, the main clinical deficiency identified in the region, and high values of Al, Zn and Mn. The results indicate that most mineral deficiencies diagnosed in those herds is due to antagonistic effects of minerals that are not deficient.

    1975-12-01

    The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.

    1986-01-01

    Gamma radiation in a set of rooms of the sector D of the Cardeal Leme Building in the Pontifica Universidade Catolica of Rio de Janeiro, and also in some outdoors ares at the PUC/RJ campus, are examined using well established experimental techniques. The exposures were obtained by using CaSO 4 :Dy thermoluminescent dosimeters and one NaI(Tl) crystal associated with a multichannel pulse height analyser to store the gamma ray spectra of the locations chosen for the measurements. Outdoors, the average of the actual readings of exposures rates obtained at PUC/RJ campus remained around 2,5x10 -2 mC/Kg.y (98 mR/year), while indoors the average exposure rates were in some cases three times higher than the equivalent average obtained outdoors. Some of potential causes to the fact that exposure to gamma radiation is, in general, higher indoors than outdoors are examined and discussed. (author) [pt

  16. Watertightness in anti-flotation slabs: MIS-RJ case

    Directory of Open Access Journals (Sweden)

    C. Britez

    Full Text Available It is common in coastal cities as Rio de Janeiro, that buildings located close to the shoreline have their basements below water table level. In most cases, the engineering solution for these buildings is to design a massive anti-flotation slab to satisfy, principally, the issues related to structural dimensioning and calculation hypothesis. On the other hand, the execution of this solution imply in significant construction problems related to reinforced concrete watertightness and durability. This paper presents a case study about challenges and solutions devised to execute an anti-flotation, 1m thick, 1200m³ reinforced concrete slab for the new Museu de Imagem e Som (MIS - Sound and Image Museum, located at 50m from the seashore, at Copacabana in Rio de Janeiro, RJ. The results show that concrete proportions, concreting plan and pouring method adopted were decisive in obtaining a watertight structure, avoiding thus the employment of traditional waterproofing alternatives.

    Full Text Available Ant species richness and diversity may be increased in more complex habitats because they provide more niches and diverse ways of exploiting the environmental resources. Because of the connection between the organisms and habitat characteristics, ants have been used as tools for environmental monitoring of disturbed areas. In this study the structure of the ant community was investigated in plots with different management strategies for the rehabilitation of a mined area at Ilha da Madeira, Itaguaí, RJ, Brazil. A different and richer ant fauna was found in plots with more native tree species than in plots with a low number of tree species or without conservationist management.

    Highlights: • Enhanced and significantly accelerated biodiesel synthesis from waste goat tallow by infrared radiation. • In situ water removal by adsorbent profoundly promotes achieving high free fatty acids (FFAs) conversion. • Process optimization and parametric interaction-effects assessment by response surface method. • Artificial Neural Network Modeling for prediction of triglycerides and FFA conversion. • At optimal conditions, product biodiesel contains 98.5 wt.% FAME. - Abstract: For the first time, an efficient simultaneous trans/esterification process for biodiesel synthesis from waste goat tallow with considerable free fatty acids (FFAs) content has been explored employing an infrared radiation assisted reactor (IRAR). The impacts of methanol to tallow molar ratio, IRAR temperature and H 2 SO 4 concentration on goat tallow conversion were evaluated by response surface methodology (RSM). Under optimal conditions, 96.7% FFA conversion was achieved within 2.5 h at 59.93 wt.% H 2 SO 4 , 69.97 °C IRAR temperature and 31.88:1 methanol to tallow molar ratio. The experimental results were also modeled using artificial neural network (ANN) and marginal improvement in modeling efficiency was observed in comparison with RSM. The infrared radiation strategy could significantly accelerate the conversion process as demonstrated through a substantial reduction in reaction time compared to conventionally heated reactor while providing appreciably high biodiesel yield. Moreover, the in situ water removal using silica-gel adsorbent could also facilitate achieving higher FFA conversion to fatty acid methyl ester (FAME). Owing to the occurrence of simultaneous transesterification of triglycerides present in goat tallow, overall 98.5 wt.% FAME content was determined at optimal conditions in the product biodiesel which conformed to ASTM and EN biodiesel specifications

    1997-01-01

    Full Text Available Phytoplankton biomass, chemical parameters and hydrology were studied in a transect 101.6 km long off Cabo Frio (RJ, Southeast Brazil, during summer (December 29 to 31, 1991 and winter (June 27 to 30, 1992. Wind induced upwelling events are frequently observed in the area during summer, becoming rare during winter. By the summer cruise a bloom of phytoplankton was observed in surface, close to the coast, with chlorophyll concentrations reaching 25.55 mg Chl-a m-3, uncoupled from the cold, nutrient rich waters of South Atlantic Central Water (SACW, found below 40 m depth. During the winter cruise, the SACW raised at the surface waters in front of Cabo Frio depicting an upwelling event.

    Full Text Available No Brasil atual, o turbulento contexto político, econômico e social tem sido terra fértil para o exame das práticas de gestão. Assim, o presente artigo tem por propósito investigar a realidade socioeconômica no município de Quissamã (RJ em conexão com a expansão dos recursos financeiros advindos do petróleo, que abasteceram os cofres públicos a partir de 1997. Para tanto, fez-se revisão bibliográfica e análise quantitativa de dados, fruto de pesquisa a documentos públicos da prefeitura. Nesta etapa, foram identificados os mecanismos de gestão e aplicação dos recursos originados no petróleo, como principais promotores do desenvolvimento local. Adicionalmente, foi estabelecida análise comparada entre Quissamã (RJ e o município vizinho Conceição de Macabu (RJ, visto que estes mantêm características territoriais e demográficas semelhantes. A despeito de Conceição não receber recursos do petróleo nos patamares de Quissamã, apresentou melhores índices de desenvolvimento. De resultado, verificou-se aumento da concentração de renda e a constatação de que os recursos públicos não geraram benefícios mais estruturantes para a população. Acredita-se que o debate proposto possa contribuir para o aperfeiçoamento das ações governamentais, restando salientar a necessidade de se aprofundar o que ora se discute, estabelecendo-se novos caminhos, num processo de melhoria da gestão de recursos públicos.

    To explore viral marketing strategies for Eclipse cigarettes used by the RJ Reynolds Company (Winston-Salem, North Carolina, USA). Analysis of previously secret tobacco industry documents and multimedia materials. The failure of RJ Reynolds' (RJR) 1988 "smokeless" cigarette, Premier, was in part due to widespread bad word of mouth about the product's flavour, quality and difficulty of use. In 1994 RJR introduced an updated version of Premier, the ostensibly "reduced risk" Eclipse cigarette. RJR developed viral marketing channels to promote Eclipse using (1) exploratory interviews to motivate consumers to spread the word about Eclipse prior to market release, (2) promotional videos featuring positive feedback from test group participants to portray majority consensus among triers, (3) "Tupperware"-like parties for Eclipse where participants received samples to pass around in their social circles and (4) the Eclipse website's bulletin board as a forum for potential users to discuss the brand in their own words. These strategies targeted the brand's likeliest adopters, recruited informal and credible representatives of the product unaffiliated with RJR, and controlled the information spread about the product. Viral marketing techniques may be particularly useful to promote new tobacco products such as Eclipse that have limited appeal and need a highly motivated audience of early adopters and acceptors. Such techniques help evade the mass rejection that could follow mass promotion, circumvent marketing restrictions, and allow tobacco companies to benefit from health claims made by consumers. Cigarette manufacturers must be held accountable for perceived health benefits encouraged by all promotional activities including viral marketing.

    On the 20th of March 2007 a large rock avalanche fell on Morsárjökull, one of the outlet glaciers from the southern part of the Vatnajökull ice cap, in south Iceland. This is considered to be one of the largest rock avalanches which have occurred in Iceland during the last decades. It is believed that it fell in two separate stages, the main part fell on the 20th of March and the second and smaller one, on the 17th of April 2007. The Morsárjökull outlet glacier is about 4 km long and surrounded by up to 1000 m high valley slopes. The outlet glacier is fed by two ice falls which are partly disconnected to the main ice cap of Vatnajökull, which indicates that the glacier is mainly fed by ice avalanches. The rock avalanche fell on the eastern side of the uppermost part of the Morsárjökull outlet glacier and covered about 1/5 of the glacier surface, an area of about 720,000 m2. The scar of the rock avalanche is located on the north face of the headwall above the uppermost part of the glacier. It is around 330 m high, reaching from about 620 m up to 950 m, showing that the main part of the slope collapsed. It is estimated that about 4 million m3 of rock debris fell on the glacier, or about 10 million tons. The accumulation lobe is up to 1.6 km long, reaching from 520 m a.s.l., to about 350 m a.s.l. Its width is from 125 m to 650 m, or on average 480 m. The total area which the lobe covers is around 720.000 m2 and its mean thickness 5.5 m. The surface of the lobe shows longitudinal ridges and grooves and narrow flow-like lobes, indicating that the debris mass evolved down glacier as a mixture of a slide and debris flow. The debris mass is coarse grained and boulder rich. Blocks over 5 to 8 m in diameter are common on the edges of the lobe up to 1.6 km from the source. No indication was observed of any deformation of the glacier surface under the debris mass. The first glaciological measurements of Morsárjökull outlet glacier were carried out in the year 1896

    Once non-biodegradable, microplastics remain on the environment absorbing toxic hydrophobic compounds making them a risk to biodiversity when ingested or filtered by organisms and entering in the food chain. To evaluate the potential of the contamination by microplastics in mussels cultivated in Jurujuba Cove, Niterói, RJ, waters of three stations were collected during a rain and dry seasons using a plankton net and later filtered. Microplastics were quantified and characterized morphologically and chemically. The results showed a high concentration of microplastics in both seasons with diversity of colors, types and sizes. Synthetic polymers were present in all samples. The presence of microplastics was probably due to a high and constant load of effluent that this area receives and to the mussel farming activity that use many plastic materials. Areas with high concentrations of microplastics could not be used for mussel cultivation due to the risk of contamination to consumers. Copyright © 2016 Elsevier Ltd. All rights reserved.

By enlisting the participation of the employees and the local population, the study allowed the identification of the main issues of environmental aspects. Based on such research, the PEA prioritized the activities carried out at FCN and considered the following topics: environmental impacts, natural resources, waste generation, biodiversity, public policies, job generation and increase of real income and conservation units. The aim of this work is to share strategies and participative methodology as well as the achievements. In the context of the Corporative Social Responsibility, the implementation of the PEA is part of the company policy in accordance with its code of the ethics to support corporative programs with special focus on environmental preservation and the appreciation of the human being, besides providing transparent and true information to internal and external publics. The results in 2015 and 2016 demonstrated a participative management between the FCN and the local population in the districts of Areias/SP, Itatiaia/RJ and Resende/RJ. Besides that, the PEA enables to strengthen the corporative relations, to maintain a dialogue with the local community and to spread out the knowledge about nuclear technology. (author)

Based on such research, the PEA prioritized the activities carried out at FCN and considered the following topics: environmental impacts, natural resources, waste generation, biodiversity, public policies, job generation and increase of real income and conservation units. The aim of this work is to share strategies and participative methodology as well as the achievements. In the context of the Corporative Social Responsibility, the implementation of the PEA is part of the company policy in accordance with its code of the ethics to support corporative programs with special focus on environmental preservation and the appreciation of the human being, besides providing transparent and true information to internal and external publics. The results in 2015 and 2016 demonstrated a participative management between the FCN and the local population in the districts of Areias/SP, Itatiaia/RJ and Resende/RJ. Besides that, the PEA enables to strengthen the corporative relations, to maintain a dialogue with the local community and to spread out the knowledge about nuclear technology. (author)

    Full Text Available The purpose of this study was analyze the biometry of the mangrove crab, Ucides cordatus (L., 1763, captured commercially in the Gargaú Mangrove (RJ, comparing common practices with the demands of Law no 52/2003 of IBAM A – Brazilian Agency of Environment and Natural Resources – and making inferences about the fishing community’s perception of the species. From April 2002 to March 2003, 571 specimens were analyzed and the highest frequency of males and females was registered in a carapace width of 6,0 6,5cm. The exploration of the mangrove crab is conducted all year round and the gear known as “redinha” is used in its capture, disrespecting the abovementioned law. However, the capture excludes ovigerous females and small-sized specimens, which reflects the fishing community’s concerns about this resource. The exploitation of this crab population probably interferes in its growth pattern, and managerial action needs to be implemented, considering not only the recommendations of scientific studies, but also the local fishermen’s knowledge of the species.

    The present work aimed the study of the dispersion profiles of radionuclides released in liquid radioactive effluents from the Central Nuclear Almirante Alvaro Alberto (CNAAA), in the Ilha Grande Bay, located in Angra dos Reis, RJ. Taking the overall activity released by liquid effluents discharge from the CNAAA in the Piraquara de Fora Bay as a reference parameter to the dilution rates scanning, the accordance level between the achieved 3 H results (1 :16) and those reported by Franklin (1 :20) can be seen as relevant. The post-1965 137 Cs concentration raise can be regarded as a consequence of the operational start up in the CNAAA, being the Ribeira Bay considered its preferential uptake, from the plume displacement high tide, as well as its retention, due to local deposition favourable trends. The evaluation of the prevailing mechanism on long half-life radio isotopes dispersion pointed out its dependence on meteorological condition parameters, during the sampling procedures. If diffusion prevailingness occurs, both 223 Ra and 224 Ra distribution pathways result in diffusion coefficients ranging from 20,12 ± 3,81 - 21,07 ± 3,91 km 2 .d -1 to a 228 Ra offshore flux and time of residence of, respectively, 3,18 ± 1,01 x 108 Bq.d-1 and 25,35 ± 0,45 days. On the other hand, an uppermost advection process provided 228 Ra offshore flux and time of residence of, respectively, 2,26 ± 0,424 x 10 8 Bq.d -1 and 13,08 ± 0,21 days. (author)

    We investigated the diet and foraging of the endemic teiid lizard Cnemidophorus littoralis in a restinga habitat in Jurubatiba, Macaé - RJ. The stomach contents were removed, analyzed and identified to the Order level. There was no relationship between C. littoralis morphological variables and number, length or volume of preys. Termites (48.7%) and larvae (35.5%) were the most important prey items which occurred in the examined lizards' stomachs. The diet did not differ between males and females. Cnemidophorus littoralis is an active forager and predominantly consumes relatively sedentary prey or prey that is aggregated in the environment. We also found an intact and undigested hatchling of the crepuscular/nocturnal gekkonid lizard Hemidactylus mabouia in the stomach of an adult male of C. littoralis, which indicates that C. littoralis is a potential source of mortality for individuals of H. mabouia in the restinga de Jurubatiba.

    Full Text Available Este artigo analisou a desigualdade ambiental em Rio das Ostras-RJ por meio do mapeamento das condições adequadas de habitação, baseada nos índices de abastecimento de água, de esgotamento sanitário, de alfabetização, de renda, de disposição do lixo e de presença de vegetação, oriundos do Censo IBGE de 2010 e de imagens de satélite Cbers-2b e Landsat-5, de 2008. Os índices foram ponderados pelo método Analitic Hierarchy Process e agregados no software ArcGis 10.0, construindo o índice de desigualdade ambiental. O município de Rio das Ostras foi selecionado por apresentar um elevado crescimento populacional entre 2000 e 2010, seguido de um significativo crescimento econômico derivado da exploração de petróleo e gás na Bacia de Campos. Nesse sentido, tornou-se importante verificar se o crescimento populacional e econômico vinha acompanhando de condições de habitação adequadas para toda a população. O resultado expôs a presença de desigualdade ambiental em Rio das Ostras, afetando principalmente a população de menor renda, com maiores porcentagens de analfabetos e localizados no limite da área urbanizada e na área rural, cujas áreas apresentaram deficiência na oferta de serviços e infraestrutura. Concluiu-se que a distribuição condições adequadas de habitação avaliada por este trabalho não é homogênea e segue a lógica de valorização da terra urbana para o processo de especulação imobiliária em Rio das Ostras. A presença da desigualdade ambiental também representa dificuldades na garantia da sustentabilidade urbana, com diversas áreas desprovidas de condições de habitação em que, por isso, acabam por impactar o meio ambiente.

    Full Text Available The aim of this project was to evaluate the Regenerative and Analogous Agroforestry Systems (SAFRA on environmental sustainability, using as indicators the biomass increase or accumulation and nutrients deposition through litter arboreal species. This work is part of PRODETAB/EMBRAPA - 39th Project – and was developed in Goura Vrindávna Farm, Paraty - RJ. 28 multipurpose arboreal species were cultivated in three agroforestry treatments, Minimum SAFRA (simplified system of the banana culture enrichment, Absolute SAFRA (dense and diversified system and Modified SAFRA (the same composition of the latter SAFRA plus soil fertilization. For evaluating nutrients deposition through litter fifteen months after planting, samples of three Safra and two control treatments, banana culture and area in fallow, were collected with 625cm2 collectors. Macro and micronutrients determinations were done in the samples. The Minimum SAFRA was the system that deposited the greatest weight in litter (32.4 t.ha-1 and the greatest content of micro and macronutrients. Excepting C and H, N was the one which presented greatest content in the five treatments, and Fe was the micronutrients of major deposition. The vegetation pruning in the SAFRA benefited the nutrients cycling and contributed to its content elevation in litter. Considering the nutrients deposition through litter, the SAFRAs were the most promissory systems in the re-establishing of these ecological functions, when compared to area in fallow and banana monoculture.

    Full Text Available RESUMO Este trabalho apresenta um modelo para determinar a fragilidade ambiental em bacias hidrográficas. O estudo foi realizado na Bacia do Rio Aldeia Velha, RJ, localizada na zona de contato e transição entre a baixada litorânea e o relevo montanhoso da Serra do Mar. Fatores que influenciam a ocorrência de processos erosivos foram integrados por algoritmos em um SIG para construção de classes de fragilidade. A análise multicriterial considerou o modelo numérico de terreno, dados oficiais sobre variáveis ambientais, imagem orbital de alta resolução e a opinião de especialistas. Através de informações secundárias sobre pedologia, intensidade das chuvas e declividade do terreno gerou-se o Mapa de Fragilidade Potencial (MFP. Através da combinação desse mapa com informações sobre uso e cobertura da terra obteve-se o Mapa da Fragilidade Emergente (MFE. Os resultados mostram que mais de 70% da área da bacia possui fragilidade ambiental considerada alta ou muito alta, tanto potencial como emergente. Os Processos Erosivos Aparentes (PEA relacionaram-se positivamente com as áreas de alta fragilidade nos produtos cartográficos finais, destacando regiões mais propensas à intensificação de movimentos de massa e prioritárias para prevenção contra perda de solo. Os modelos geraram informações importantes para o planejamento territorial, possibilitando um zoneamento acessível e de fácil atualização para as prefeituras municipais e organizações da sociedade civil, inclusive para o monitoramento das áreas de alta fragilidade ambiental.

    Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Tb, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 31 Schlosser Drive, Rochelle Park, New Jersey (RJ003), was conducted on July 14, 1991. Results of the survey demonstrated no radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria.

    We summarize and extend previous results on the comparison of threshold resummation, performed, using softcollinear effective theory (SCET), in the Becher-Neubert approach, to the standard perturbative QCD formalism based on factorization and resummation of Mellin moments of partonic cross sections. We show that the logarithmic accuracy of this SCET result can be extended by half a logarithmic order, thereby bringing it in full agreement with the standard QCD result if a suitable choice is made for the soft scale μ s which characterizes the SCET result. We provide a master formula relating the two approaches for other scale choices. We then show that with the Becher-Neubert scale choice the Landau pole, which in the perturbative QCD approach is usually removed through power- or exponentially suppressed terms, in the SCET approach is removed by logarithmically subleading terms which break factorization. Such terms may become leading for generic choices of parton distributions, and are always leading when resummation is used far enough from the hadronic threshold.

    Full Text Available The gekkonid lizard Hemidactylus mabouia is an exotic species in Brazil and is found in different ecosystems. This species was recorded at Ilha Grande, RJ, one of the largest insular remains of the Atlantic Rainforest in Brazil. In this study, the occurrence of H. mabouia was determined throughout the island, including the rain forest, restinga and anthropic environments. We used the active search method in points along 19 trails that surround Ilha Grande. At each regular interval of 100 m, we searched for the presence of H. mabouia. The species was recorded in a total of 100 points among the 719 sampled and, in all cases, the occurrence of the lizard corresponded to points located in anthropic or perianthropic areas. As most of Ilha Grande is covered by dense tropical rain forest, we believe this has restricted the invasion of H. mabouia in natural environments within the island.

    Full Text Available Diazepam suppositories are widely used by children and elderly, and require close attention to quality control because it is a controlled prescription drug. The objective of the study was to analyze diazepam suppositories manipulated in Campos dos Goytacazes, RJ, to verify if they are within the required quality standards, and offer safety and efficiency to patients. We analyzed samples of 5mg diazepam suppositories acquired in five randomly selected pharmacies, identified as Pharmacy A, Pharmacy B, Pharmacy C, Pharmacy D, and Pharmacy E. We ran tests on average weight, organoleptic control, hardness, melting point, and dissolution. Data was analyzed and compared with the requirements of the Brazilian Pharmacopoeia. This analysis was made over a table in Excel. We conclude that only C Pharmacy was approved in all tests, and this is the only laboratory that has analyzed the quality of the product warranty. Laboratories A, B, D and E have been approved in some tests, and failed one or more tests. To ensure quality control, suppositories needed to pass in all tests, which was not the case of these labs. Therefore, we recommended the following procedures to the investigated laboratories: changes in packaging, greater precision in handling, quality control prior to dispensing the product, and efficient pharmaceutical care service.

    We summarize and extend previous results on the comparison of threshold resummation, performed using soft-collinear effective theory (SCET) in the Becher-Neubert approach, to the standard perturbative QCD formalism based on factorization and resummation of Mellin moments of partonic cross sections. We show that the logarithmic accuracy of the SCET result can be extended by half a logarithmic order, thereby bringing it in full agreement with the standard QCD result if a suitable choice is made for the soft scale μ{sub s} which characterizes the SCET result. We provide a master formula relating the two approaches for other scale choices. We then show that with the Becher-Neubert scale choice the Landau pole, which in the perturbative QCD approach is usually removed through power- or exponentially suppressed terms, in the SCET approach is removed by logarithmically subleading terms which break factorization. Such terms may become leading for generic choices of parton distributions, and are always leading when resummation is used far enough from the hadronic threshold.

    In many areas of the world, studies of marine debris are conducted with an emphasis on analyzing their composition, quantification and distribution on sandy beaches. However, in Brazil, studies are still restricted to some areas of the coast, and the quantities and the spatial and temporal patterns are unknown. To enhance the marine debris information in these areas, we selected the Itaipu and Itacoatiara beaches in Niterói, RJ, to collect, quantify and qualify the solid residues present in their sands. We collected 12 samples and recorded 118.39 kg of residues in Itaipu and 62.94 kg in Itacoatiara. At both beaches, the largest portion of debris was located on the upper part of the beach. Several debris items were related to food and drink consumption on the beaches, which indicated the contribution of beach users to pollution. Most of the debris was plastic. The greatest amount of debris was found at Itaipu in January and February and at Itacoatiara in January and March, months related to both the holiday season and abundant rainfall. The results demonstrated the necessity to implement an Environmental Education project for these areas to reduce its degradation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Dioctophyma renale é o maior nematóide conhecido. Seu parasitismo tem sido descrito em várias espécies animais e no homem. Este helminto localiza-se preponderantemente no rim direito ou livre na cavidade abdominal de seus hospedeiros. Sinais clínicos como abatimento, inapetência e emagrecimento podem estar associados à dioctofimose, apesar do curso da parasitose ser muitas vezes assintomático nos animais e pessoas infectadas. O único tratamento eficaz é a remoção cirúrgica do parasito e, em alguns casos, do rim afetado. O presente trabalho teve como objetivo relatar um caso de parasitismo por Dioctophyma renale em um cão no município de Valença/RJ. O animal foi resgatado por apresentar um tumor na pata e também hérnia perianal, mas ao caminho da policlínica veterinária apresentou também uma urina de odor fétido, que através da urinálise observou-se presença de ovos compatíveis com os de Dioctophyma renale.Dado o diagnóstico e localização do parasito, o animal foi encaminhado para a Policlínica de Pequenos Animais, da Faculdade de Medicina Veterinária de Valença, onde optou-se pela nefrectomia do rim afetado.

    Full Text Available Sanitation actions are rare in the communities of Manguinhos, so evaluation of the sanitary conditions of the river waters and the peridomestic soils of the communities allows the diagnosis of the risk of contamination. This study evaluated coliform levels (total coliforms and Escherichia coli by the filter membrane method, and parasitological (by adapted Lutz and Baermann-Moraes methods in the waters and soils of the Faria-Timbó, Jacaré and Canal do Cunha Rivers that pass through the communities of the Territory of Manguinhos, RJ, according to the standards established in Brazilian legislation. In all points of the rivers, the water was unfit, with an average level of Escherichia coli 3,800 times higher than that standardized in CONAMA Resolution No. 274/2000. Larvae, helminths eggs and protozoan oocysts were observed. Soil samples were also unfit, with mean total coliform level 77,000 times higher than that considered acceptable by SMAC Resolution 468/2010. The Escherichia coli average level was 53,000 times higher than that permitted by the legislation. However, helminths eggs were found in only one soil sample. It was concluded that the lack of sanitation in this locality results in the high coliform and parasitological levels of the river waters and in the peridomestic soils, and that immediate modifications are needed to the Brazilian environmental paradigm, which uses its water bodies as sewage disposal ditches.

  20. Royal jelly promotes DAF-16-mediated proteostasis to tolerate β-amyloid toxicity in C. elegans model of Alzheimer's disease.

    Wang, Xiaoxia; Cao, Min; Dong, Yuqing

    2016-08-23

    Numerous studies have demonstrated that dietary intervention may promote health and help prevent Alzheimer's disease (AD). We recently reported that bee products of royal jelly (RJ) and enzyme-treated royal jelly (eRJ) were potent to promote healthy aging in C. elegans. Here, we examined whether RJ/eRJ consumption may benefit to mitigate the AD symptom in the disease model of C. elegans. Our results showed that RJ/eRJ supplementation significantly delayed the body paralysis in AD worms, suggesting the β-amyloid (Aβ) toxicity attenuation effects of RJ/eRJ. Genetic analyses suggested that RJ/eRJ-mediated alleviation of Aβ toxicity in AD worms required DAF-16, rather than HSF-1 and SKN-1, in an insulin/IGF signaling dependent manner. Moreover, RJ/eRJ modulated the transactivity of DAF-16 and dramatically improved the protein solubility in aged worms. Given protein solubility is a hallmark of healthy proteostasis, our findings demonstrated that RJ/eRJ supplementation improved proteostasis, and this promotion depended on the transactivity of DAF-16. Collectively, the present study not only elucidated the possible anti-AD mechanism of RJ/eRJ, but also provided evidence from a practical point of view to shed light on the extensive correlation of proteostasis and the prevention of neurodegenerative disorders.

The percent cover of the most abundant organisms was not similar between treatments at Urca after four months, while in Catalão, the similarity was 72% in the second month. The faster community development and recovery at the most polluted area was probably related to the existence of simple and resilient communities in more impacted areas.O objetivo deste estudo foi descrever e comparar a sucessão das comunidades bentônicas da região entre-marés, em duas áreas na Baía de Guanabara, RJ, Brasil: Urca, uma área sujeita a moderado nível de poluição orgânica, e Catalão, uma área extremamente poluída.

    This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng.) Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS) and the Sandy Strip Closed Shrub (SSCS) formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalariform perforation plates, wood parenchyma scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees may be due to the greater diameters of their branches. Our results suggest that M. glabra develops structural adaptations to the restinga micro-environmental variations during its development.

E-mail: jairopinheirodasilva@gmail.com Toxoplasma gondii is a protozoan parasite that infects up to a third of the world's population. Infection is mainly acquired by ingestion of food or water that is contaminated with oocysts shed by cats or by eating undercooked or raw meat containing tissue cysts and by blood transfusion or organ transplantation. Primary infection is usually subclinical but in some patients cervical lymphadenopathy or ocular disease can be present. Infection acquired during pregnancy may cause severe damage to the fetus. In immunocompromised patients, reactivation of latent disease can cause life-threatening encephalitis. Diagnosis of toxoplasmosis can be established by direct detection of the parasite or by serological techniques. The aim of the present study was verify the seroprevalence of toxoplasmosis in cornea donors of Rio de Janeiro, Brazil. IgM and IgG anti- T. gondii antibodies were investigated in 426 sera of corneal donors by using the indirect fluorescent antibody test (IFAT and immunoenzymatic assay (ELISA techniques. The participants were selected by convenience sampling. Demographic information of study subjects including their gender, age, cause of death and home region were recorded. Out of 426 serum samples, 338 (79.34% and 17 (3.99% were positive regarding anti-T. gondii IgG and IgM antibodies ELISA

    The Saco do Mamangua is a narrow and elongated gulf located along the southeastern coast of Brazil, in the state of Rio de Janeiro (RJ). It is surrounded by high relieves, which form a peculiar environment called riá, with little river input and limited water exchange with the Atlantic Ocean. These features make the Saco do Mamangua an ideal environment to study sedimentary carbon cycling under well-constrained boundary conditions in order to investigate if tropical coastal environments serve dominantly as potential carbon sinks or sources. In this work we integrate geochemical data from marine sediments and pore waters in the Saco do Mamangua with mapping of benthic microbial communities, in order to unravel the biogeochemical carbon cycling linked to the production of biogenic methane. Our results reveal that carbon cycling occurs in two parallel pathways. The Saco do Mamangua receives organic carbon both by surface runoff and by primary production in the water column. A large part of this organic carbon is buried within the sediment resulting in the production of biogenic methane, which gives rise to methane seepages at the sea floor. These methane seeps sustain methanotrophic microbial communities in the sediment pore water, but also escapes into the atmosphere by ebullition. Consequently, the sediments of Saco do Mamangua acts simultaneously as carbon sink and carbon source. Future work will allow us to accurately quantify the actual carbon fluxes and calculate the net carbon balance in the local environment.

    Full Text Available One of the most important challenges in the study of aging is to discover compounds with longevity-promoting activities and to unravel their underlying mechanisms. Royal jelly (RJ has been reported to possess diverse beneficial properties. Furthermore, protease-treated RJ (pRJ has additional pharmacological activities. Exactly how RJ and pRJ exert these effects and which of their components are responsible for these effects are largely unknown. The evolutionarily conserved mechanisms that control longevity have been indicated. The purpose of the present study was to determine whether RJ and its related substances exert a lifespan-extending function in the nematode Caenorhabditis elegans and to gain insights into the active agents in RJ and their mechanism of action.We found that both RJ and pRJ extended the lifespan of C. elegans. The lifespan-extending activity of pRJ was enhanced by Octadecyl-silica column chromatography (pRJ-Fraction 5. pRJ-Fr.5 increased the animals' lifespan in part by acting through the FOXO transcription factor DAF-16, the activation of which is known to promote longevity in C. elegans by reducing insulin/IGF-1 signaling (IIS. pRJ-Fr.5 reduced the expression of ins-9, one of the insulin-like peptide genes. Moreover, pRJ-Fr.5 and reduced IIS shared some common features in terms of their effects on gene expression, such as the up-regulation of dod-3 and the down-regulation of dod-19, dao-4 and fkb-4. 10-Hydroxy-2-decenoic acid (10-HDA, which was present at high concentrations in pRJ-Fr.5, increased lifespan independently of DAF-16 activity.These results demonstrate that RJ and its related substances extend lifespan in C. elegans, suggesting that RJ may contain longevity-promoting factors. Further analysis and characterization of the lifespan-extending agents in RJ and pRJ may broaden our understanding of the gene network involved in longevity regulation in diverse species and may lead to the development of nutraceutical

    Full Text Available This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng. Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS and the Sandy Strip Closed Shrub (SSCS formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalarifor perforation plates, ood parenchya scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees ay be due to the greater diaeters of their branches. ur results suggest that . glabra develops structural adaptations to the restinga micro-environmental variations during its development.Este trabalho objetiva caracterizar a estrutura anatômica do lenho de Mollinedia glabra, ocorrente em duas formações vegetais contíguas na restinga da Praia Virgem, município de Rio das Ostras, RJ.

    Full Text Available Royal jelly (RJ has been used worldwide for many years as medical products, health foods and cosmetics. Since RJ contains testosterone and has steroid hormone-type activities, we hypothesized that it may have beneficial effects on osteoporosis. We used both an ovariectomized rat model and a tissue culture model. Rats were divided into eight groups as follows: sham-operated (Sham, ovariectomized (OVX, OVX given 0.5% (w/w raw RJ, OVX given 2.0% (w/w RJ, OVX given 0.5% (w/w protease-treated RJ (pRJ, OVX given 2.0% (w/w pRJ, OVX given 17β-estradiol and OVX given its vehicle, respectively. The Ovariectomy decreased tibial bone mineral density (BMD by 24%. Administration of 17β-estradiol to OVX rats recovered the tibial BMD decrease by 100%. Administration of 2.0% (w/w RJ and 0.5–2.0% (w/w pRJ to OVX rats recovered it by 85% or more. These results indicate that both RJ and pRJ are almost as effective as 17β-estradiol in preventing the development of bone loss induced by ovariectomy in rats. In tissue culture models, both RJ and pRJ increased calcium contents in femoral-diaphyseal and femoral-metaphyseal tissue cultures obtained from normal male rats. However, in a mouse marrow culture model, they neither inhibited the parathyroid hormone (PTH-induced calcium loss nor affected the formation of osteoclast-like cells induced by PTH in mouse marrow culture system. Therefore, our results suggest that both RJ and pRJ may prevent osteoporosis by enhancing intestinal calcium absorption, but not by directly antagonizing the action of PTH.

    Recent studies suggest that royal jelly (RJ) and its related substances may have antiaging properties. However, the molecular mechanisms underlying the beneficial effects remain elusive. We report that the effects of RJ and enzyme-treated RJ (eRJ) on life span and health span in Caenorhabditis elegans (C elegans) are modulated by the sophisticated interplays of DAF-16, SIR-2.1, HCF-1, and 14-3-3 proteins. Dietary supplementation with RJ or eRJ increased C. elegans life span in a dose-dependent manner. The RJ and eRJ consumption increased the tolerance of C elegans to oxidative stress, ultraviolet irradiation, and heat shock stress. Our genetic analyses showed that RJ/eRJ-mediated life-span extension requires insulin/IGF-1 signaling and the activities of DAF-16, SIR-2.1, HCF-1, and FTT-2, a 14-3-3 protein. Earlier studies reported that DAF-16/FOXO, SIR-2.1/SIRT1, FTT-2, and HCF-1 have extensive interplays in worms and mammals. Our present findings suggest that RJ/eRJ-mediated promotion of longevity and stress resistance in C elegans is dependent on these conserved interplays. From an evolutionary point of view, this study not only provides new insights into the molecular mechanisms of RJ's action on health span promotion in C elegans, but also has imperative implications in using RJ/eRJ as nutraceuticals to delay aging and age-related disorders. © The Author 2014.

    Full Text Available The aim of this study were investigate the reproductive biology of the fish Leporinus copelandii, a specie at risk of extinction in the lower Paraíba do Sul River basin. During a period of 14 months, a total of 143 females of red-piau were captured, between Itaocara and Campos dos Goytacazes cities (RJ, Brazil. A histological study shows four stages of the oocyte development (I, II, III and IV and five stages of the reproductive cycle of females: rest (1, initial maturation (2A, intermediary (2B, advanced (2C and spawned (4 were identified. The pattern of L. copelandii oocyte development suggests development type synchronous in two groups, characterizing total spawning. Spawned females were captured in November, two months after the peak of frequency of competent females for reproduction. Histologically, a little occurrence of empty follicles was observed in spawned females. The medium diameter of the type IV oocyte of the spawned females (1475.1 ± 884.3mm was significantly larger (Tukey, P <0.001; VC = 41.73%; n = 259 than advanced maturation females (1202.6 ± 245.3mm, what allows suggesting that the study place probably doesn't represent the reproductive area of L. copelandii.

    Full Text Available The basic sanitation comprises several services that are essential to the maintenance of people's health and well-being. The populations that have an appropriate water supply, sewage collection and treatment, proper garbage disposal, among other services, are protected from diseases and have access to a minimum comfort to live in a safe way. In spite of the importance of these services, to the extent to be characterized as “basic”, several populations, national or worldwide, suffer for the lack or the complete privation of sanitation, live without access to quality water, their waste is thrown under open air and their garbage is disposed in inappropriate sites, what causes health and environmental impacts. This work is being accomplished in a community called Santa Cruz, located in Campos dos Goytacazes, RJ, and aims to carry out a survey about the local sanitary reality, especially about the quality of the water supplied to the population. 100 inhabitants of that community were interviewed and answered a questionnaire. Among the results, 22% of the interviewees consume the water that comes to their homes without any type of treatment, 47% consider the supply water as being of poor quality and 7% don't own home water tanks. After the interviews, bacteriological and physicochemical water analyses were performed in fifteen samples collected in the community. The test results indicated that the collected water was out of the drinking water standards, and therefore, inappropriate for human consumption.

    Full Text Available Restraint and cold stress increase both corticosterone and glycemia, which lead to oxidative damages in hepatic tissue. This study assessed the effect of royal jelly (RJ supplementation on the corticosterone level, glycemia, plasma enzymes and hepatic antioxidant system in restraint and cold stressed rats. Wistar rats were allocated into no-stress, stress, no-stress supplemented with RJ and stress supplemented with RJ groups. Initially, RJ (200mg/Kg was administered for fourteen days and stressed groups were submitted to chronic stress from the seventh day. The results showed that RJ supplementation decreases corticosterone levels and improves glycemia control after stress induction. RJ supplementation also decreased the body weight, AST, ALP and GGT. Moreover, RJ improved total antioxidant capacity, SOD activity and reduced GSH, GR and lipoperoxidation in the liver. Thus, RJ supplementation reestablished the corticosterone levels and the hepatic antioxidant system in stressed rats, indicating an adaptogenic and hepatoprotective potential of RJ.

    Royal jelly (RJ) is a honeybee product containing proteins, carbohydrates, fats, free amino acids, vitamins, and minerals. As its principal unsaturated fatty acid, RJ contains 10-hydroxy-2-decenoic acid (10-HDA), which may have antitumor and antibacterial activity and a capacity to stimulate collagen production. RJ has attracted interest in various parts of the world for its pharmacological properties. However, the effects of RJ on ultraviolet (UV)-induced photoaging of the skin have not been reported. In this study we measured the 10-HDA content of RJ by high-performance liquid chromatography and tested the effects of RJ on UVB-induced skin photoaging in normal human dermal fibroblasts. The effects of RJ and 10-HDA on UVB-induced photoaging were tested by measuring procollagen type I, transforming growth factor (TGF)-β1, and matrix metalloproteinase (MMP)-1 after UVB irradiation. The RJ contained about 0.211% 10-HDA. The UVB-irradiated human skin fibroblasts treated with RJ and 10-HDA had increased procollagen type I and TGF-β1 productions, but the level of MMP-1 was not changed. Thus RJ may potentially protect the skin from UVB-induced photoaging by enhancing collagen production.

    Full Text Available Jabuticaba (Myrciariasp is a fruit native to the Atlantic Forest, belonging to the Myrtaceae family, and commonly found in Brazil. It presents considerable economic potential because it can be consumed as raw fruit or processed food. In Varre-Sai, RJ, jabuticaba is strongly used in the industrialization of alcoholic beverages. The production of fermented alcoholic alternative is used to avoid waste, and make the most of the considerable nutritional value of the fruit. The content of anthocyanins in jabuticaba ranges from 310 and 315mg/100g, relatively high value compared to other fruits considered rich in antioxidants. Therefore, sensory analyses of jabuticaba alcoholic beverages produced in Varre-Sai can improve the quality of the product and potential sales. Given that the part of jabuticaba rich in phenolic compounds is the bark, the whole use of the fruit is the best alternative to take advantage of its benefits. Sensory analysis evaluated the acceptance of fermented alcoholic of Jabuticaba, in relation to its overall rating attributes, color, flavor and aroma, based on a 9-point hedonic scale, with ends named strongly disliked (1 and strongly liked (9; as well as purchase intention of tasters by a 5-point hedonic scale, with anchor points would certainly buy (5 and would not certainly buy (1. The results showed that the products had good acceptance and the fermented Sweet Tinto was rated best in all attributes, obtaining 90.18% frequency in the acceptance of hedonic scale, with respect to global acceptance. Even in the hypothetical situation of purchase, it received 74.5% of the votes in the good range of the scale. This shows that the alcoholic fermented beverages may be an alternative for the consumption of antioxidants, and that their production can improve the income of farmers as well as help avoid fruit wasting.

    Full Text Available No compartimento serapilheira-solo, a fauna do solo exerce importante papel na disponibilização de nutrientes, uma vez que é responsável pela regulação da comunidade de microrganismos decompositores da matéria orgânica e pela fragmentação desse material. Este trabalho objetivou avaliar a riqueza e abundância da fauna edáfica, bem como sua distribuição vertical, em área de restinga periodicamente inundada na Ilha da Marambaia, RJ, em duas épocas distintas, verão (chuvosa e inverno (seca. Foram coletadas 10 amostras de serapilheira e de solo na profundidade de 0-5 cm, em que foram feitas extrações da fauna por meio de extratores do tipo Berlese-Tüllgren. Observou-se aumento da abundância da fauna edáfica do período seco para o chuvoso, enquanto a riqueza de grupos taxonômicos não foi modificada. Em ambas as épocas, os grupos de maior ocorrência foram Formicidae e Collembola. Quanto à distribuição vertical, verificou-se a preferência dos organismos pelo compartimento serapilheira, no período chuvoso, e pelo solo, no período seco. A microfagia e a saprofagia representaram as principais formas de utilização dos recursos alimentares, seguidos da predação, sugerindo melhor estruturação do habitat no ecossistema. Além disso, a ocorrência de grupos que só são percebidos em ambientes não perturbados indica que o ecossistema de restinga da Ilha da Marambaia, no momento em que foi avaliado, ano de 2002, encontrava-se pouco ou nada degradado e em bom estado de conservação.

    Full Text Available Neste artigo, debatemos a urbanização brasileira no século XXI e a heterogeneidade da periferia metropolitana fluminense. Utilizando o exemplo da cidade de São Gonçalo (RJ, listamos referências bibliográficas e apontamos elementos que chamam atenção para a necessidade de entender o papel das cidades periféricas que, apesar da primazia metropolitana, apresentam maior integração com a região metropolitana, compondo uma parte do que alguns autores convencionaram como “periferia integrada”. Como periferia integrada, vemos que os indicadores de mobilidade pendular, o aumento das centralidades, a modernização do território e o índice de desenvolvimento nos obrigam a flexionar alguns consensos sobre essa cidade periférica lida ainda, como cidade-dormitório.

    Full Text Available O objetivo deste trabalho foi fazer a caracterização morfométrica a partir de alguns parâmetros físicos da bacia hidrográfica do rio Debossan, Nova Friburgo, RJ. Para isso, gerou-se inicialmente o Modelo Digital de Elevação Hidrologicamente Consistente (MDEHC a partir de cartas topográficas do IBGE, na escala 1:50.000, utilizando o sistema de informações geográficas, através dos softwares ArcVIEW e Arc/INFO. A partir do MDEHC, foram calculados alguns parâmetros morfométricos para o estudo do comportamento hidrológico da bacia. A área de drenagem encontrada foi de 9,9156 km² e o perímetro, de 17,684 km. A bacia hidrográfica do rio Debossan tem formato alongado, coeficiente de compacidade de 1,5842, fator de forma de 0,3285 e índice de circularidade de 0,3985. A densidade de drenagem obtida para a bacia foi de 2,3579 km/km². A forma mais alongada da bacia hidrográfica indica que a precipitação pluviométrica sobre ela se concentra em diferentes pontos, concorrendo para amenizar a influência da intensidade de chuvas, as quais poderiam causar maiores variações da vazão do curso d'água.The objective of this work was to perform a morphometric characterization based on some physical parameters. In order to do so, a Hydrologically Consistent Digital Elevation Model (HCDEM was generated from IBGE topographical maps, scale 1:50.000, using as database and analysis the system of geographic information, by means of the ArcVIEW and Arc/INFO version 8.3 systems. From this, some morphometric parameters of a previous study on the hydrologic behavior of the watershed were calculated. The drainage area was 9,9156 Km² and 17,684 km in perimeter. The Debossan river watershed was proven not easily subject to floods as the compacity coefficient was far from the unit (1.5842 and its shape factor presented a low value (0.3285. Such fact can still be proven by the circularity index value (0.3985. The drainage density was 2,3579 Km

    Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. The surveys typically include direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this commercial property at Route 17(S) and Becker Avenue, Rochelle Park, New Jersey (RJ001), was conducted in 1986. Measurements taken at the commercial property located at Route 17(S) and Becker Avenue indicate slightly elevated gamma exposure rates in three areas of the parking lot. Although results of analysis of the asphalt disclosed radionuclide concentrations in excess of the applicable criterion, their presence is due to naturally radioactive substances in asphalt patching materials and is not associated with material from the MCW site. Therefore, it is recommended that this site be eliminated from consideration for inclusion in the DOE remedial action program. 5 refs., 2 figs., 3 tabs

    The aim of the present study was to evaluate different concentrations of royal jelly (RJ) supplemented extenders for post-thaw quality and incubation resilience of goat spermatozoa. Semen samples were collected from five goats. Pooled semen were diluted with soybean lecithin-based extender without RJ (control) or supplemented with different concentrations (0.25, 0.5 and 0.75%) of RJ (RJ0.25, RJ0.5, RJ0.75 respectively), at a final concentration of 150 × 10 6 spermatozoon/mL. Semen samples were assessed for sperm motility, plasma membrane integrity using hypoosmotic swelling test (HOST) damaged acrosome using FITC-Pisum sativum agglutinin (PSA-FITC) and DNA integrity using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). The addition of RJ (0.5%, 0.75%) led to higher percentages of subjective motilities (55.33 ± 2.29%, 57.67 ± 2.58%) compared to control and RJ0.25 groups (49.00 ± 2,80%, 51.67 ± 3.09%) (P  0.05).

    E. M. Almeida

    Full Text Available The present study assessed the fruiting pattern, bird foraging behavior, and sugar content of ripe fruits of two sympatric species of Rubiaceae (Psychotria brasiliensis and P. nuda. This study was carried out in an Atlantic forest area on Ilha Grande, RJ, between August 1998 and July 1999. Fruit production occurred year round, with a peak of mature P. brasiliensis fruits in December 1998 and another of P. nuda in February of 1999. Lipaugus lanioides (Cotingidae, Baryphtengus ruficapillus (Momotidae and Saltator similis (Emberizidae made the most frequent foraging visits to fruiting P. brasiliensis, so that L. lanioides and B. ruficapillus removed the fruits with sallying maneuvers while S. similis gleaned the fruits. Lipaugus lanioides was by far the most important consumer, and potentially the main disperser of P. brasiliensis. Birds of this genus are heavy frugivores in the tropical forests and are widely assumed to be important seed dispersers. The fruits were analyzed quantitatively and qualitatively in relation to the amounts of sucrose and starch. Psychotria brasiliensis (the visited species showed the smallest quantity of sucrose and the highest amount of starch. These findings suggest that what may influence the birds' choice of fruit is the proportion of starch in the Psychotria species studied here rather than the carbohydrate composition.

    Full Text Available O objetivo deste trabalho foi caracterizar o comportamento hidrológico, o volume de entrada e saída de água da bacia hidrográfica do rio Debossan, onde se localiza uma importante estação de captação de água, administrada pela Concessionária de Águas e Esgotos de Nova Friburgo LTDA. (CAENF, inserida na Reserva Ecológica de Macaé de Cima, Município de Nova Friburgo, Rio de Janeiro. Para isso, foram obtidos dados de vazão e precipitação diários do período de janeiro de 2002 a dezembro de 2004. A partir desses dados, foram calculados alguns parâmetros hidrológicos, como vazão específica e deflúvio. A precipitação média observada nos três anos foi de 2.163 mm, sendo que os meses de dezembro/2002 e janeiro/2003 apresentaram os máximos valores. A vazão média anual no período foi de 0,86 m³/s, apresentando o mês de dezembro de 2002 com maior índice e setembro de 2004 com o menor. O balanço hídrico, em termos médios anuais nos três anos de medições, apresentou uma evapotranspiração de 1.923,04 mm, equivalendo a 88% da precipitação convencional. Pode-se dizer que o ecossistema florestal exerce efeito tamponante sobre a quantidade de água da bacia hidrográfica, mantendo uma grande vazão nos meses de menor pluviosidade. Ao analisar a relação entre a entrada de água na bacia, o uso atual do solo e a quantidade de água produzida, concluiu-se que uma bacia hidrográfica bem preservada tem fundamental importância na manutenção constante da vazão ao longo do ano, além da visível participação na qualidade da água.The objective of this work was to characterize the hydrological behavior and the volume of water entering and leaving the Debossan river watershed, where an important water captation plant is situated, managed by the Nova Friburgo Water and Sewage Treatment Company LTDA (CAENF, within the 'Macaé de Cima' Ecological Reserve, Nova Friburgo-RJ.

    Full Text Available Resilience, as a property of social-ecological systems, is related to the ability of such systems to adapt and deal with perturbations. This study examined the characteristics in a community of artisanal fishermen, using some of the resilience indicators (flexibility, capacity to organize and capacity to learn. The flexibility indicator represents the economic dependence on the natural resource; the capacity to organize indicator informs about participation in decision-making and in community organizations; and the capacity to learn indicator refers to the perception of environmental alterations in relation to human activity. Together, these indicators can inform about the adaptive capacity of the community and its relationship with resource management. Semi structured interviews were conducted in the months of January, April, July and August of 2012 in the community of Praia Grande and surroundings (Paraty/RJ (n=22. As to the flexibility indicator, 59.1% of the fishermen interviewed have another source of income, being tourism the main activity among them (36.4%. Most of the fishermen (77.2% use more than one type of fishing technique which may either reduce pressure on the fishing resource or have an opposite effect, if it is the case of the use of more intensive techniques, such as trawling. Regarding the fishermen’s capacity to organize, it was found and discussed the low participation on decision-making regarding fishing, especially because the area of the study is situated in a context of social-environmental conflicts with conservation areas. As for the capacity to learn, the results indicate that the fishermen perceive the human activity as an agent responsible for the perturbations in the natural environment, and they suggest different solutions in face of the decrease of each target species. Through the use of the resilience indicators it was possible to identify the attributes that allow the adaptation of the community to

    Full Text Available The alternative use of natural products, like royal jelly (RJ, may be an important tool for the treatment of infections caused by antibiotic-resistant bacteria. RJ presents a large number of bioactive substances, including antimicrobial compounds. In this study, we carried out the chemical characterization of fresh and lyophilized RJ and investigated their antibacterial effects with the purpose of evaluating if the lyophilization process maintains the chemical and antibacterial properties of RJ. Furthermore, we evaluated the antibacterial efficacy of the main fatty acid found in RJ, the 10-hydroxy-2-decenoic acid (10H2DA. Chromatographic profile of the RJ samples showed similar fingerprints and the presence of 10H2DA in both samples. Furthermore, fresh and lyophilized RJ were effective against all bacteria evaluated; that is, the lyophilization process maintains the antibacterial activity of RJ and the chemical field of 10H2DA. The fatty acid 10H2DA exhibited a good antibacterial activity against Streptococcus pneumoniae. Therefore, it may be used as an alternative and complementary treatment for infections caused by antibiotic-resistant S. pneumoniae.

    Polonium-210 ( 210 Po), a short-lived member from the uranium series, is broadly distributed in Nature being among all alpha-emitters the major contributor to the internal dose in man. Studies of diets have shown that marine foods are important sources of this radionuclide. The levels of 210 Po have been determined in three highly consumed marine species, the fishes Sardinella brasiliensis (sardine) and Thunnus atlanticus (tuna), and the shrimp Litopenaeus brasiliensis, purchased from the Niteroi (RJ, Brazil) fish market, and caught along the coast of the state of Rio de Janeiro. Doses of 210 Po were determined for the entire organisms and for some tissues and organs, such as eyes, heart, gills, muscle, stomach liver, intestine and pyloric caecal (fishes) or eyes, head content, exoskeleton, muscle, hepatopancreas and pleopods. 210 Po is not uniformly distributed within these species, the highest levels being observed for sardine in the intestine (1634.6 mBq g-1), tuna in pyloric caecal (4656.1 mBq g-1) and shrimp in the hepatopancreas (1460.5 mBq g-1). The 210 Po activities in sardine, tuna and shrimp, calculated on a mean whole-organism basis, were 64.6, 34.5 and 39.5 Bq kg-1 (dry weight) respectively, with corresponding concentration factors of 7.2 x104, 3.8 x104 and 4.4 x104. Considering body distribution, almost 60% of the total activity is concentrated in the pyloric caecal of both fishes and in the hepatopancreas of the shrimp. In turn, the edible parts concentrate much less activity. (author)

    Full Text Available Abstract Background: Phenylhydrazine (PHZ as a strong oxidant agent causes variety of toxic effects including alterations in the biochemical and cardiac tissue. The aim of the present study was to investigate the effects of royal jelly (RJ and vitamin C (vit C against PHZ-induced cardiotoxicity in mice. Materials and Methods: Adult male mice were randomly assigned to eight groups of eight mice each. PHZ was administered to four groups of mice at a dose of 60 mg/kg per 48 hours intraperitoneally for 35 days. Three of these groups received vit C (250 mg/kg per day intraperitoneally, RJ (100 mg/kg per day orally and vit C+RJ with same doses four hours before PHZ administration, respectively. A vehicle-treated control group and vit C, RJ and vit C+RJ control groups were also included. Results: RJ and vit C significantly decreased (p< 0.05 the serum level of malondialdehyde and creatine kinase (CK-BM that had been increased by PHZ. Also, RJ and vit C increased the total antioxidant capacity and supraxoid dismutase serum that had been decreased by induced PHZ. Moreover, RJ and vit C could improve the tissue damages induced by PHZ such as diffused edema, hemorrhage, congestion, hyaline exudates, necrosis and also fibrosis tissue in heart tissue. Conclusion: It seems that Vit C and RJ can minimize PHZ-induced cardiotoxicity in mouse through oxidative reactions inhibition.

    Full Text Available In the Western honey bee, Apis mellifera, queens and workers have different longevity although they share the same genome. Queens consume royal jelly (RJ as the main food throughout their life, including as adults, but workers only eat worker jelly when they are larvae less than 3 days old. In order to explore the effect of RJ and the components affecting longevity of worker honey bees, we first determined the optimal dose for prolonging longevity of workers as 4% RJ in 50% sucrose solution, and developed a method of obtaining long lived workers. We then compared the effects of longevity extension by RJ 4% with bee-collected pollen from rapeseed (Brassica napus. Lastly, we determined that a water soluble RJ protein obtained by precipitation with 60% ammonium sulfate (RJP60 contained the main component for longevity extension after comparing the effects of RJ crude protein extract (RJCP, RJP30 (obtained by precipitation with 30% ammonium sulfate, and RJ ethanol extract (RJEE. Understanding what regulates worker longevity has potential to help increase colony productivity and improve crop pollination efficiency.

  12. The Effects of Royal Jelly on Fitness Traits and Gene Expression in Drosophila melanogaster.

    Directory of Open Access Journals (Sweden)

    John R Shorter

    Full Text Available Royal Jelly (RJ is a product made by honey bee workers and is required for queen differentiation and accompanying changes in queen body size, development time, lifespan and reproductive output relative to workers. Previous studies have reported similar changes in Drosophila melanogaster in response to RJ. Here, we quantified viability, development time, body size, productivity, lifespan and genome wide transcript abundance of D. melanogaster reared on standard culture medium supplemented with increasing concentrations of RJ. We found that lower concentrations of RJ do induce significant differences in body size in both sexes; higher concentrations reduce size, increase mortality, shorten lifespan and reduce productivity. Increased concentrations of RJ also consistently lengthened development time in both sexes. RJ is associated with changes in expression of 1,581 probe sets assessed using Affymetrix Drosophila 2.0 microarrays, which were enriched for genes associated with metabolism and amino acid degradation. The transcriptional changes are consistent with alterations in cellular processes to cope with excess nutrients provided by RJ, including biosynthesis and detoxification, which might contribute to accelerated senescence and reduced lifespan.

    The redox cycling of manganese has pronounced effects on the adsorption of trace elements onto oxide surfaces is leaving these unavailable for the biota. Specific constants for the kinetics oxidation reaction of Mn in mangrove ecosystems have been measured. Water samples with different characteristics were collected in a tidal creek in a mangrove forest growth at Itacuruca, RJ. The methodology used to study the kinetics was, incubation of the water, in laboratory, with Mn-54. The oxides precipitates were filtered at constant intervals of time. The Mn-54 decay on the filters and filtrates were counted, for 600 s, in HPGe and associated electronics ORTEC. Ln A x t diagram showed an autocatalytic kinetic behavior. Temperature, pH, O{sub 2} dissolved, salinity, Mn (II) and Mn (IV) were appraised. The rate constant k{sup '}{sub 1}1 varied from 1,0 x 10{sup -5} to 4,0 x 10{sup -5} s{sup -1}. The k{sup '}{sub 2} rate constant had a larger variation, according to the other kinetic model that shows more of a heterogeneous affect, or catalysis via bacteria. We found a mean half life for Mn(II) of 12 h for the homogeneous kinetics in the mangrove. Rate constants increased with the pH, temperature, O{sub 2} dissolved, tide height, and decrease with salinity. (author)

    2015-01-01

    Full Text Available Victimisation of women through cyber stalking is one of the most serious crimes against women. Many countries including India have developed laws regulating cyber stalking. This article argues that since both, restorative justice (RJ and therapeutic jurisprudence (TJ are victim oriented, the issue of cyber stalking of women may be dealt with by RJ process and the laws in this regard must be analysed by the legal actors with a background in RJ and TJ philosophy. India had earlier taken up therapeutic punishment policy to enforce rights of the accused. But the modern principles of TJ have still not been considered in the RJ background in cyber stalking cases. This article therefore examines whether RJ and TJ principles can replace retributive principles for cyber stalking victimisation. It also examines the Indian cyber stalking law from RJ and TJ perspectives to assess its effectiveness for victims.

  16. Dangerous liaisons?: A feminist and restorative approach to sexual assault

    2011-01-01

    Full Text Available The appropriateness of restorative justice (RJ for gendered violence offences such as domestic violence and sexual assault has always been and still is highly contested. This paper focuses on the appropriateness of RJ measures in addressing sexual assault, primarily with reference to experience of restorative dialogues as practiced at the Centre for Victims of Sexual Assault in Copenhagen, and it takes a feminist approach to the application of RJ measures to sexual assault. Within this framework, the paper tackles two issues in particular: the privacy element of RJ versus the public aspect of the criminal justice system (CJS, and the intersection of the CJS and RJ in cases of sexual assault. In relation to the relationship between CJS and RJ, the authors argue that RJ could be used for victims of sexual assault, not primarily as part of diversion programmes, but when offered apart from and/or parallel to the CJS. In relation to the private/public debate, the authors argue that while RJ encounters, by taking place in highly confidential settings, might have a negative impact on efforts by women’s movements to move violence against women out of the private and into the public realm, creating high standard alternatives for individual women who are in need of support and constantly generating public debate about gendered violence is a good feminist response to this complex issue.

Si les pratiques de codage et de décodage de la démarche alchimique ainsi que l’attention portée aux transformations des états de la matière constituent indéniablement des points de convergence avec la philosophie leibnizienne, il ne nous semble néanmoins pas possible de conclure de là à une influence de la philosophie chimique, et en particulier de la notion de semence, sur la constitution de la monade leibnizienne.Comparing the Leibniz’s Oedipus chymicus, written in 1710, with its possible reference, the homonymous text by J.J.

    Full Text Available A região noroeste fluminense conta com um importante arranjo produtivo local no setor de beneficiamento de rochas ornamentais e de revestimento. Essa atividade é responsável por boa parte da renda local, empregando muitas pessoas. O principal produtor da região é o município de Santo Antônio de Pádua/RJ, que possui 154 empresas (78 pedreiras e 76 serrarias. A grande atividade de extração e beneficiamento das rochas vem causando na região problemas ambientais, pois durante as etapas de produção muito se perde devido a técnicas rudimentares e a deficiência no tratamento dos efluentes, o que acaba gerando impactos ao Rio Pomba, onde estes são lançados. O objetivo deste trabalho de pesquisa foi realizar um diagnóstico do uso da água no processo produtivo e a partir daí avaliar as diferentes alternativas para se ter um consumo otimizado e um tratamento dos efluentes a fim de minimizar os danos ambientais. Foram realizados alguns estudos de casos de caráter exploratório, pesquisas bibliográficas, entrevistas com proprietários, funcionários e profissionais ligadas ao setor de rochas e visitas técnicas a empresas da região. Os resultados apontam para uma falta de preparo e conhecimento técnico dos empresários e funcionários ao uso de novas tecnologias aliadas às questões ambientais no que se refere ao tratamento e consumo de água, principalmente para as pequenas empresas.

    Full Text Available Cisplatin (CDDP is one of the most active cytotoxic agents in the treatment of cancer and has adverse side effects such as nephrotoxicity and hepatotoxicity. The present study was designed to determine the effects of royal jelly (RJ against oxidative stress caused by CDDP injury of the kidneys and liver, by measuring tissue biochemical and antioxidant parameters and investigating apoptosis immunohistochemically. Twenty-four Sprague Dawley rats were divided into four groups, group C: control group received 0.9% saline; group CDDP: injected i.p. with cisplatin (CDDP, 7 mg kg-1 body weight i.p., single dose; group RJ: treated for 15 consecutive days by gavage with RJ (300 mg/kg/day; group RJ + CDDP: treated by gavage with RJ 15 days following a single injection of CDDP. Malondialdehyde (MDA and glutathione (GSH levels, glutathione S-transferase (GST, glutathione peroxidase (GSH-Px, and superoxide dismutase (SOD activities were determined in liver and kidney homogenates, and the liver and kidney were also histologically examined. RJ elicited a significant protective effect towards liver and kidney by decreasing the level of lipid peroxidation (MDA, elevating the level of GSH, and increasing the activities of GST, GSH-Px, and SOD. In the immunohistochemical examinations were observed significantly enhanced apoptotic cell numbers and degenerative changes by cisplatin, but these histological changes were lower in the liver and kidney tissues of RJ + CDDP group. Besides, treatment with RJ lead to an increase in antiapoptotic activity hepatocytes and tubular epithelium. In conclusion, RJ may be used in combination with cisplatin in chemotherapy to improve cisplatin-induced oxidative stress parameters and apoptotic activity.

This work aimed to deterime the values of Kc for different phenological phases of common bean plants (Phaseolus vulgaris L. of the cultivar UENF-47. Determination of Kc values was performed using a weighing lisimeter and results were compared with values obtained through the FAO 56 standard. Results showed that the adjustment equations proposed by Allen et al. (1998 were adequate for fitting the values of Kc obtained in this experiment. It has been shown that the crop coefficients for phenological phases 3 and 4 proposed by Allen et al. (1998 are adequate

    Full Text Available Os investimentos em infraestrutura viária são grandes alavancadores do desenvolvimento econômico de uma região. Os projetos de pavimento flexível são geralmente feitos para uma vida útil de 5 anos, assim após esse prazo são necessárias intervenções para restauração. Em Belford-Roxo, RJ, a pavimentação da maior parte da cidade não atende as condições básicas que a população necessita. Buscou-se particularizar tal problema, segundo a ótica e os processos de avaliação contidos no Manual de Restauração de Pavimentos Asfálticos do Departamento Nacional de Infraestrutura de Transportes utilizando o método da avaliação objetiva de superfície pela determinação do Índice de Gravidade Global. A aplicação adaptada para vias locais mostrou-se efetiva, pois relata de forma simplificada a condição funcional do pavimento. Uma vez que pouco se usam essas técnicas, essa aplicação se faz pertinente para um adequado projeto de restauração evitando aplicação de recursos desnecessários.

    Full Text Available Royal jelly (RJ is popular among consumers around the world due to its perceived health benefits. The purpose of this study was to assess the levels of free and total amino acid profile as well as protein content in order to characterize Bulgarian RJ samples. A total of 17 fresh and commercial RJ samples from different regions of Bulgaria were analyzed. The results obtained show that proline (Pro, lysine (Lys, methionine (Met, aspartic acid (Asp, cysteine (Cys, histidine (His were major free amino acids (FAAs in RJ. The average content of Pro was 2.3 mg/g. The FAA content ranged from 5.5 to 6.2 mg/g of RJ. The most abundant total amino acids (TAAs were aspartic acid (Asp, glutamic acid (Glu, lysine (Lys, leucine (Leu, serine (Ser and proline (Pro. The average TAA content in fresh and commercial RJ were 129±10 and 114±8 mg/g, respectively. The results obtained for TAA content were used to establish a range for amino acid composition of Bulgarian RJ. The content of proteins was higher in fresh RJ than in commercial samples and this difference was significant (p<0.05. The following ranges were observed for fresh and commercial samples 14.7–17.3 and 12.5–14.9 mg/g, respectively. DOI: http://dx.doi.org/10.4314/bcse.v29i3.16

    Full Text Available Background: Royal jelly has been shown to have antioxidant and antidiabetic effects. The objective of this study was to evaluate the protective effect of RJ against kidney damage in streptozotocin induced diabetic rats. Methods: Thirty two male Wistar rats were divided randomly into four groups (n=8 per group. Normal control and diabetic control groups received 1cc/day distilled water, normal RJ-treated and diabetic RJ-treated groups received 100mg RJ/kg body weight daily. Diabetes was induced by intraperitoneal injection of streptozotocin. At the end of the experiment, urine and kidney samples were collected for biochemical and histopathological analysis. Results: The results showed that diabetes could increase levels of urine urea, total protein and albumin significantly, and could decrease the levels of creatinine and uric acid in urine. In the kidney tissue homogenates, catalase activity and antioxidant power were significantly lower, whereas malondialdehyde levels were significantly higher in diabetic group when compared with control group. Diabetic rats showed severe histological changes in kidney tissues. Treatment of diabetic rats with RJ improved significantly all of these parameters. Conclusion: The present study revealed that treatment with RJ resulted in significant improvement in histopathological alterations in kidney tissue and urine parameters of diabetic rats. This could be due to its antioxidant activity and the ability of RJ for scavenging the free radicals released in diabetes. These findings suggest that RJ has protective effects on kidneys affected by diabetes mellitus.

    The content of 10-hydroxy-trans-2-decenoic acid (10-HDA), a marker compound in royal jelly (RJ), is the most important criterion in grading RJ for commercial trade and varies with its origin. To identify the effect of geographical origin on 10-HDA content in RJ, 138 samples were collected from 19 provinces of China (divided into three groups) produced by either Apis mellifera ligustica Spinola, 1806 or a hybrid of A. m. ligustica and Apis mellifera carnica Pollman, 1879 and analyzed for moisture, sugar, crude protein, ash, acid, and 10-HDA concentration. The results show that RJ from western China has a significantly higher 10-HDA level (2.01 +/- 0.05%) than those from northeastern (1.87 +/- 0.05%) and eastern (1.75 +/- 0.03%) China. RJ secreted by hybrid bees contained more 10-HDA (1.89 +/- 0.03%) than that secreted by A. m. ligustica (1.78 +/- 0.03%). The 10-HDA content of RJ produced during flowering of rape (Brassica campestris L.), lime (Tilia amurensis Ruprecht), and vitex (Vitex negundo L. variety heterophylla (Franch.) Rehder) was 1.92, 1.80, and 1.68%, respectively. The results would be helpful during the process of price determination of RJ by providing some basis of geographical, bee strain, and botanical information for commercial trade.

    Royal jelly (RJ), secreted by honeybee workers, plays diverse roles as nutrients and defense agents for honeybee biology and human health. Despite being reported to be glycoproteins, the glycosylation characterization and functionality of RJ proteins in different honeybee species are largely unknown. An in-depth N-glycoproteome analysis and functional assay of RJ produced by Apis mellifera lingustica (Aml) and Apis cerana cerana (Acc) were conducted. RJ produced by Aml yielded 80 nonredundant N-glycoproteins carrying 190 glycosites, of which 23 novel proteins harboring 35 glycosites were identified. For Acc, all 43 proteins glycosylated at 138 glycosites were reported for the first time. Proteins with distinct N-glycoproteomic characteristics in terms of glycoprotein species, number of N-glycosylated sites, glycosylation motif, abundance level of glycoproteins, and N-glycosites were observed in this two RJ samples. The fact that the low inhibitory efficiency of N-glycosylated major royal jelly protein 2 (MRJP2) against Paenibacillus larvae (P. larvae) and the absence of antibacterial related glycosylated apidaecin, hymenoptaecin, and peritrophic matrix in the Aml RJ compared to Acc reveal the mechanism for why the Aml larvae are susceptible to P. larvae, the causative agent of a fatal brood disease (American foulbrood, AFB). The observed antihypertension activity of N-glycosylated MRJP1 in two RJ samples and a stronger activity found in Acc than in Aml reveal that specific RJ protein and modification are potentially useful for the treatment of hypertensive disease for humans. Our data gain novel understanding that the western and eastern bees have evolved species-specific strategies of glycosylation to fine-tune protein activity for optimizing molecular function as nutrients and immune agents for the good of honeybee and influence on the health promoting activity for human as well. This serves as a valuable resource for the targeted probing of the biological

    Full Text Available Alzheimer’s disease (AD is the most common form of dementia characterized by aggregation of amyloid β (Aβ and neuronal loss. One of the risk factors for AD is high cholesterol levels, which are known to promote Aβ deposition. Previous studies have shown that royal jelly (RJ, a product of worker bees, has potential neuroprotective effects and can attenuate Aβ toxicity. However, little is known about how RJ regulates Aβ formation and its effects on cholesterol levels and neuronal metabolic activities. Here, we investigated whether RJ can reduce cholesterol levels, regulate Aβ levels and enhance neuronal metabolic activities in an AD rabbit model induced by 2% cholesterol diet plus copper drinking water. Our results suggest that RJ significantly reduced the levels of plasma total cholesterol (TC and low density lipoprotein-cholesterol (LDL-C, and decreased the level of Aβ in rabbit brains. RJ was also shown to markedly ameliorate amyloid deposition in AD rabbits from Aβ immunohistochemistry and thioflavin-T staining. Furthermore, our study suggests that RJ can reduce the expression levels of β-site APP cleaving enzyme-1 (BACE1 and receptor for advanced glycation end products (RAGE, and increase the expression levels of low density lipoprotein receptor-related protein 1 (LRP-1 and insulin degrading enzyme (IDE. In addition, we found that RJ remarkably increased the number of neurons, enhanced antioxidant capacities, inhibited activated-capase-3 protein expression, and enhanced neuronal metabolic activities by increasing N-acetyl aspartate (NAA and glutamate and by reducing choline and myo-inositol in AD rabbits. Taken together, our data demonstrated that RJ could reduce cholesterol levels, regulate Aβ levels and enhance neuronal metabolic activities in AD rabbits, providing preclinical evidence that RJ treatment has the potential to protect neurons and prevent AD.

    Full Text Available To alleviate the deleterious effect of heat stress during summer conditions on male rabbits’ reproduction, 40 V Line adult rabbit bucks (on av. 8 mo old were divided into 4 experimental groups and exposed to temperatures ranging from 23 to 36°C. Bucks in the 1st, 2nd, 3rd, and 4th group were supplemented with 0, 50, 100 or 150 mg of Chinese royal jelly (RJ/kg twice per week, respectively, over a 20-wk period. Semen quality and blood biochemical constituents were evaluated. RJ at any dose exhibited a significant increase (P<0.05 in rabbits’ sperm concentration, total sperm output, sperm motility, live sperm and normal sperm compared to the untreated controls. Plasma total protein, albumin, globulin, glucose and high density lipids (HDL concentrations were significantly (P<0.05 boosted in the RJ groups compared to the controls. In contrast, RJ treatment resulted in a significant (P<0.05 reduction in plasma total lipids, triglycerides, cholesterol and low density lipids (LDL concentrations. Treatment with RJ significantly boosted (P<0.05 testosterone concentration in the RJ groups to reach 110, 120 and 128%, respectively, of the control group. Improved kidney and liver functions were observed in the RJ bucks groups where plasma creatinine, urea concentrations, aspartate aminotransferase and alanine aminotransferase enzyme activities were significantly (P<0.05 decreased by RJ treatments. Treating bucks subjected to heat stress by different RJ doses increased (P<0.05 total antioxidant capacity to 106, 111 and 115% of basal, but significantly reduced (P<0.05 malondialdehyde and thiobarbituric acid reactive substances compared to the untreated. It was concluded that Chinese royal jelly supplementation for heat-stressed male rabbits can counteract summer infertility and improve their physiological status.

    Full Text Available Background: An adverse effect of oxymetholone (OXM, an anabolic-androgenic steroid used as energetic medicine, is reproductive toxicity. Royal jelly (RJ is an efficient antioxidant that has been used to treat reproductive problems. In this study, we investigated the effects of RJ on OXM-induced oxidative injuries in mouse testes. Methods: Male mice were divided into four groups. Two groups of mice were administered OXM (5 mg/kg/day, p.o. for 28 days. One of these groups received RJ (100 mg/kg/day, p.o. concurrently. A vehicle-treated control group and a RJ control group were also included. Results: The OXM-treated group showed a significant decrease in the serum testosterone concentration and spermatogenic activities, along with many histological alterations. OXM treatment also caused a significant decrease in catalase activity with an increase in lipid peroxidation in the mouse testes. The above-noted parameters were restored to near normal levels by RJ co-administration. Conclusion: The results demonstrate that RJ protects against OXM-induced reproductive toxicities.

    Full Text Available The Western honey bee (Apis mellifera is a social insect characterized by caste differentiation in which the queen bee and worker bees display marked differences in morphology, behavior, reproduction, and longevity despite their identical genomes. The main causative factor in caste differentiation is the food fed to queen larvae, termed royal jelly (RJ. Alternative splicing (AS is an important RNA-mediated post-transcriptional process in eukaryotes. Here we report AS changes in A. mellifera after being fed either A. mellifera RJ or A. cerana RJ. The results demonstrated that the RJ type affected 4 types of AS in adult A. mellifera: exon skipping, intron retention, alternative 5’ splice sites, and alternative 3’splice sites. After feeding with A. cerana RJ, AS occurred in many genes in adult A. mellifera that encode proteins involved in development, growth, the tricarboxylic acid cycle, and substance metabolism. This study provides the first evidence that heterospecific RJ can influence the AS of many genes related to honey bee development and growth.

  18. The Phenotypic Effects of Royal Jelly on Wild-Type D. melanogaster Are Strain-Specific.

    Directory of Open Access Journals (Sweden)

    Stefanie L Morgan

    Full Text Available The role for royal jelly (RJ in promoting caste differentiation of honeybee larvae into queens rather than workers is well characterized. A recent study demonstrated that this poorly understood complex nutrition drives strikingly similar phenotypic effects in Drosophila melanogaster, such as increased body size and reduced developmental time, making possible the use of D. melanogaster as a model system for the genetic analysis of the cellular mechanisms underlying RJ and caste differentiation. We demonstrate here that RJ increases the body size of some wild-type strains of D. melanogaster but not others, and report significant delays in developmental time in all flies reared on RJ. These findings suggest that cryptic genetic variation may be a factor in the D. melanogaster response to RJ, and should be considered when attempting to elucidate response mechanisms to environmental changes in non-honeybee species.

    Full Text Available O trabalho discute temas relacionados à distribuição de sedimentos costeiros, parâmetros granulométricos e modelos bidimensionais de transporte de sedimentos. Parte-se da hipótese de que a disposição dos materiais na superfície de fundo das enseadas permite o diagnóstico de processos associados à hidrodinâmica marinha e sua participação no controle do transporte e distribuição dos sedimentos costeiros. O objetivo central é então caracterizar a textura superficial do depósito costeiro e apresentar correlações entre os parâmetros estatísticos que permitam o diagnóstico de processos relacionados à distribuição e ao transporte dos sedimentos no sistema praia-antepraia. Como área de pesquisa, foram selecionadas três enseadas no município de Arraial do Cabo (RJ. As etapas metodológicas partiram da definição de uma malha amostral, coleta de 96 amostras de sedimentos em profundidades entre 1 e 23 metros, seguido por análises granulométricas em laboratório, determinação de parâmetros estatísticos e cálculo do modelo de tendências de transporte de sedimentos (GSTA. Os resultados apontam a ocorrência majoritária de areias finas (41,6% e médias (17,7% moderadamente bem selecionadas como o principal depósito nas enseadas, no entanto, além dos depósitos palimpsestos, núcleos de deposição de areias grossas (14,6% e muito grossas (8,3% e, por outro lado, areias muito finas (5,2% e siltes (6,2% também foram identificados e discutidos à luz de sua significância ambiental. Quanto ao modelo de transporte, o melhor ajuste (65% foi feito com o padrão FB, que indica sedimentos mais finos e mais bem selecionados na direção do transporte. Conclui-se que os depósitos palimpsestos são responsáveis pelo abastecimento da praia emersa e que os esforços de interpretação dos parâmetros estatísticos e a geração de resultados de transporte de sedimentos a partir de modelos não hidrodinâmicos geram informa

    Abstract. This study evaluated the pupa-productivity of the entomologic surveillance according methodology used by the official Program for Dengue Control in Brazil (PDCB for Aedes aegypti (Linnaeus and Aedes albopictus (Skuse in Parati, RJ, Brazil. The highest number of A. aegypti pupae were found in drains (31%, bottles and cans (23%; and the highest number of A. albopictus pupae were found in bottles and cans (24%, and plant vases (21%. Of the total pupae identified 84.3% and 79.3% of A. aegypti and A. albopictus respectively were collected in small receptacles: bottles, plants vase, tires, bromeliads and tree holes. These productivities are not supported by literature and can be explained by the restrictions of access for the bigger receptacles and lack of training of the agents. The study points out the importance which the small receptacles can have on vector densities in urban environment despite of their productivity and conclude that the entomology surveillance methodology for dengue used in PDCB has no efficacy to identify the bigger and more productive receptacles. This conclusion suggests that this inefficacy can be an important factor for the failures on dengue vector control in Brazil.

    Full Text Available Introduction: Studies have proposed that royal jelly(RJ has various biological activities in different cells and tissues. Since it has been demonstrated that RJ contains compounds having desirable effects on central neurons system and neural functions, the present study aimed to investigate the effect of royal jelly on learning and memory in rats. Methods: Male wistar rats were divided into two groups, the royal jelly and the control. In the RJ group, the rats received a food that contained 3% RJ instead of regular food for 10 days. Then learning and memory were investigated in these animals through both passive avoidance learning test(1 day and 1 week after receiving electrical shock and Morris water maze test(1 day and 1 week after a 4-day learning period. Results: The study results indicated that the food containing RJ in the RJ group significantly increased the time of the first entrance to the dark room one week after the electrical shock in passive avoidance learning test. In other words, the findings suggest an improvement of learning and memory in RJ group. In the acquisition phase of Morris water maze test, rats receiving RJ found the underwater escape plate during less time and distance comparing with the control group. Furthermore, one week after the acquisition phase, in the retention phase, rats spent more time in the quadrant in which the escape plate was previously located. Conclusion: The present study findings propose that Royal Jelly can improve cognitive processes through positive effects on neural functions and probably has a significant influence on prevention and therapy of some neuronal disorders.

    A new CZE method was developed and compared with HPLC for the determination of (E)-10-hydroxy-2-decenoic acid (10-HDA) in royal jelly (RJ) samples of different geographical origin. The results obtained with the CZE method were highly correlated with those of HPLC (p HDA/mL), a good sensitivity (LOD and LOQ were 0.002 and 0.004 mg/mL, respectively) and a satisfactory instrumental repeatability with respect to migration time and peak area (RSD% less than 1.0 and 2.0% on migration time for intra- and interday assay, respectively and less than 2.0 and for 4.0% on peak area for intra- and interday assay, respectively). The 10-HDA content in RJ ranged from 0.8 to 3.2 g/100 g of RJ and a significant difference (p < 0.05) was found between the Italian and extra-European average values: 2.5 and 1.6 g/100 g of RJ, respectively, according to the CZE data. The possibility of application of CZE for routine analyses on RJ and RJ based products to verify their authenticity is highlighted here.

    Symbiosis between legumes and rhizobia leads to the formation of N2-fixing root nodules. In soybean, several host genes, referred to as Rj genes, control nodulation. Soybean cultivars carrying the Rj4 gene restrict nodulation by specific rhizobia such as Bradyrhizobium elkanii We previously reported that the restriction of nodulation was caused by B. elkanii possessing a functional type III secretion system (T3SS), which is known for its delivery of virulence factors by pathogenic bacteria. In the present study, we investigated the molecular basis for the T3SS-dependent nodulation restriction in Rj4 soybean. Inoculation tests revealed that soybean cultivar BARC-2 (Rj4/Rj4) restricted nodulation by B. elkanii USDA61, whereas its nearly isogenic line BARC-3 (rj4/rj4) formed nitrogen-fixing nodules with the same strain. Root-hair curling and infection threads were not observed in the roots of BARC-2 inoculated with USDA61, indicating that Rj4 blocked B. elkanii infection in the early stages. Accumulation of H2O2 and salicylic acid (SA) was observed in the roots of BARC-2 inoculated with USDA61. Transcriptome analyses revealed that inoculation of USDA61, but not its T3SS mutant in BARC-2, induced defense-related genes, including those coding for hypersensitive-induced responsive protein, which act in effector-triggered immunity (ETI) in Arabidopsis. These findings suggest that B. elkanii T3SS triggers the SA-mediated ETI-type response in Rj4 soybean, which consequently blocks symbiotic interactions. This study revealed a common molecular mechanism underlying both plant-pathogen and plant-symbiont interactions, and suggests that establishment of a root nodule symbiosis requires the evasion or suppression of plant immune responses triggered by rhizobial effectors. © The Author 2016.

    Full Text Available Este trabalho avalia a viabilidade técnica e econômica de se implantar um sistema de coleta de águas pluviais em uma instituição de ensino e uma residência, ambas localizadas no município de Campos dos Goytacazes, RJ. A pluviometria da cidade, área de captação e a estimativa do consumo de água não potável foi estimada para a Universidade Candido Mendes e uma residência dimensionada para cinco moradores. O custo de implantação, manutenção e valor da água tratada foi usado para calcular a viabilidade econômica do sistema. A precipitação na década de 2000 é significativamente maior do que na década de 1990. Os quatro primeiros e os dois últimos meses do ano são os mais chuvosos, enquanto que junho a agosto são mais secos. Apesar da água coletada atender a 100% da demanda, o projeto não é economicamente viável na residência. Na universidade, a coleta atenderia a 27% da demanda anual, no entanto, seria economicamente viável. O armazenamento e uso de água pluvial em áreas urbanas colaboram para a preservação do meio ambiente, é uma ferramenta de educação ambiental, evita enchentes, escassez e traz benefícios econômicos devido a redução do consumo de água tratada. Sua implantação em residência poderia ser incentivada com atos governamentais, como a redução de impostos. Para as empresas, além de redução de custos, é um sistema que pode compor o marketing verde, um seguimento de mercado em ascensão.

    Full Text Available Estudos fenológicos podem servir de subsídio para ações de colheita de sementes e recuperação de áreas degradadas, contribuindo para a conservação das espécies florestais. Este trabalho teve como objetivo conhecer a época de floração e frutificação de 21 espécies arbóreas nativas em área fragmentada de Mata Atlântica em Itaboraí, RJ. Foram acompanhadas mensalmente 91 matrizes, no período de janeiro a dezembro de 2011. A maior parte das espécies floresceu no final da estação seca e início da chuvosa, tendo sido observada correlação moderada e negativa entre floração e fotoperíodo. Observaram-se dois picos de frutificação: de março a abril para as espécies zoocóricas, e de setembro a outubro para espécies não zoocóricas, com correlação positiva entre precipitação e frutificação de espécies zoocóricas. Foi alta a incidência de patógenos nos frutos, comprometendo a produção de sementes de Machaerium hirtum, Melanoxylon brauna, Machaerium brasiliense e Psidium guineense. Outras espécies apresentaram baixa produção de frutos, como Andira sp., Swartzia oblata, Guarea guidonea e Enterolobium glaziovii. A sincronia de floração e frutificação entre as matrizes foi baixa para a maioria das espécies. A falta de trabalhos de fenologia para a maioria das espécies estudadas (52% reforça a necessidade de pesquisa para a região de estudo.

    Full Text Available Background: Diabetes is the most common endocrine disease. It has adverse effects on male reproductive function. Royal Jelly (RJ has antioxidant and anti-diabetic effects and show protective effects against diabetes. Objective: This study was conducted to evaluate the effect of RJ on histopathological alterations of the testicular tissue in streptozotocin (STZ-induced diabetic rats. Materials and Methods: In this experimental study, 28 adult Wistar rats were randomly divided into control (C, royal jelly (R, diabetic (D and RJ-treated diabetic (D+R groups. Diabetes was induced by a single intraperitoneal injection of STZ at 50 mg/kg body weight (BW. The rats from the R and D+R groups received daily RJ (100 mg/kg BW for 6 wks orally. Hematoxylin-Eosin staining was used to analyze histopathological changes including: tunica albuginea thickness (TAT, seminiferous tubules diameter (STsD, Johnsen’s score, tubular differentiation index (TDI, spermiogenesis index (SPI, Sertoli cell index (SCI, meiotic index (MI, and mononuclear immune cells (MICs in testes. The antioxidant status was examined by evaluating testicular levels of ferric reducing antioxidant power (FRAP and catalase (CAT activity. Results: Histological results of the testis from diabetic rats showed significant decrease in STsD, Johnsen’s score, TDI, SPI, SCI and MI, and significant increase in TAT and MICs, while administration of RJ significantly reverted these changes (p<0.05. RJ treatment markedly increased activity of CAT and FRAP. There were significant differences in FRAP levels among C (13.0±0.5, RJ (13.4±0.3, D (7.8±0.6 and D+R (12.4±0.7 groups (p<0.05. Conclusion: RJ improved diabetes-induced impairment in testis, probably through its antioxidant property.

    Full Text Available Introduction & Objective: Wound healing is the process of repairing following injury to the skin and other soft tissues. Following injury, inflammatory response occurs and the cells below the dermis begin to increase collagen production, later on, the epithelial tissue is regenerated. Royal jelly (RJ is a bee product. There are many reports on pharmacological activity of RJ on experimented animals. The purpose of this study was to investigate the effect of RJ on the induction of wound healing of sterile incision in Balb/C mice. Materials & Methods: In this experimental study which was conducted at Shahr-e-kord University of Medical Sciences in 60 female Balb/C mice (8 weeks old were selected. The mice were anesthetized with ether. The dorsal fur of the animals was shaved and sterilized with alcohol, and then a longitudinal para vertebral full thickness incision of 10mm long was made. The animals were then divided into six equal groups. In group one (negative control, nothing was applied to the wound. Group 2 (positive control was treated with nitrofurazon ointment, group 3 was treated with RJ 200 mg/kg daily, group 4 was treated with RJ 200 mg/kg every two days, group 5 was treated with RJ 300 mg/kg daily, group 6 treated with RJ 300 mg/kg every two days. Royal jelly was topically used on the wounds. The wound length was measured with vernier capilar every two days until the complete healing was occurred. The data were analyzed with SPSS version 11.5 using Kruscal Walis tests. Results: There was a significant difference between groups 1, 2 with the other groups (p0.015. Conclusion: The results of this study indicated that daily application of RJ possesses betters wound healing effects than nitrofurazon.

Soil samples were collected at 0-10 and 10 -30 cm depth in two times; dry period (August of 2004, May of 2005 and August of 2005 and in the rainy period (December of 2004 in different sections: at the hillside shoulder (TS, backslope (TM and footslope (TI positions. In the samples soil chemical and physical analyses were accomplished. Were evaluated the soil aggregate stability; the bulk density (BD and the total volume of pores (TVP, total organic carbon (TOC and soil fertility. To study the multidimensional effect of soil attributes the Principal Component Analysis (PCA was applied. The pastures areas showed a good aggregation levels, in the different times and depths evaluated. The grasses Tifton 85 and Braquiária propitiated a higher TOC contribution in the depth of 0-10 cm and also larger aggregate weight in the class> 2,0mm, in the dry period. Higher values of BD were observed in the TI. In the rainy period it was observed a BD reduction and TVP increase, mainly for the Suázi areas. In a general way, the positions of the hillside TS and TM were the ones that showed the higher values for the physical and chemical attributes indicating a better soil quality in these areas. In the TI area the lowest levels of soil quality were observed, possibly for the accentuated steepness of this last position of the slope in relation to the other positions. The PCA separated the areas in function of seasonal variation. The dry season presented the higher correlation values with soil quality attributes such as the aggregation indexes and TOC. The aggregate weight distribution in function of the size classes, especially > 2,0 mm, MGD, MWD and TOC were a indicative

    Full Text Available Purpose. One of the common side effects experienced by head and neck cancer patients on chemoradiotherapy is mucositis. Severe mucositis may be controllable by limiting cancer therapy, but it has resulted in decreasing the completion rate of chemoradiotherapy. The efficacy of royal jelly (RJ as prophylaxis against chemoradiotherapy-induced mucositis was evaluated through clinical scoring of oral and pharyngeal mucositis. Methods. In this randomized, single-blind (physician-blind, clinical trial, 13 patients with head and neck cancer requiring chemoradiation were randomly assigned to two groups. Seven patients assigned to the study group received RJ, and 6 patients were assigned to the control group. RJ group patients took RJ three times per day during treatment. The patients in both groups were evaluated twice a week for the development of mucositis using Common Terminology Criteria for Adverse Events version 3.0. Results. A significant reduction in mucositis was seen among RJ-treated patients compared with controls (P<0.001. Conclusion. This study demonstrated that prophylactic use of RJ was effective in reducing mucositis induced by chemoradiotherapy in head and neck cancer patients. However, further studies are needed because of the small sample size and the absence of double blinding.

    Dry eye is a multifactorial disease characterized by ocular discomfort and visual impairment. Lacrimal gland function has been shown to decrease with aging, a known potent risk factor for dry eye. We have previously found that orally administrated royal jelly (RJ) restored tear secretion in a rat model of dry eye. We examined the effects of RJ oral administration on dry eye in this prospective, randomized, double-blind, placebo-controlled study. Forty-three Japanese patients aged 20-60 years with subjective dry eye symptoms were randomized to an RJ group (1200 mg/tablet, six tablets daily) or a placebo group for 8 weeks. Keratoconjunctival epithelial damage, tear film break-up time, tear secretion volume, meibum grade, biochemical data, and subjective dry eye symptoms based on a questionnaire were investigated at baseline, and at 4 and 8 weeks after intervention. Adverse events were reported via medical interviews. In the RJ group, tear volume significantly increased after intervention (p = 0.0009). In particular, patients with a baseline Schirmer value of ≤10 mm showed a significant increase compared with baseline volume (p = 0.0005) and volume in the placebo group (p = 0.0051). No adverse events were reported. We also investigated the effect of RJ (300 mg/kg per day) administration using a mouse model of dry eye. Orally repeated administration of RJ preserved tear secretion, potentially through direct activation of the secretory function of the lacrimal glands. Our results suggest that RJ improves tear volume in patients with dry eye. Registered NO. the University Hospital Medical Information Network in Japan (UMIN000014446).

MÉTODOS: Estudo transversal com 418 alunas do ensino médio de três escolas de diferentes perfis, localizadas na cidade do Rio de Janeiro, RJ, em 2010. Aplicou-se questionário estruturado, abordando características sociodemográficas, comportamento sexual e avaliação da consulta ginecológica. Utilizou-se o teste de Qui-quadrado (Yates e o t de Student, adotando-se p < 0,05. RESULTADOS: Alunas dos colégios privado e público apresentaram perfis semelhantes e diferiram daquelas da rede pública estadual que tiveram nível socioeconômico mais baixo, menor escolaridade dos responsáveis, predominância da raça negra, maior número de parceiros, gestações e histórico de violência sexual. As médias de idades da menarca e sexarca foram semelhantes entre as estudantes e a primeira consulta ginecológica foi significativamente mais tardia nas alunas da rede estadual. A maioria referiu conhecimento sobre anticoncepção e doenças sexualmente transmissíveis, porém pequena parte obteve essas orientações na consulta. As estudantes manifestaram desejo de que o profissional investisse mais tempo, paciência e disponibilidade no atendimento. CONCLUSÕES: O atendimento ginecológico na adolescência é insatisfatório segundo a avaliação das adolescentes estudadas. As usuárias dos serviços privados submetem-se à consulta ginecológica em idade mais precoce do que aquelas que têm acesso apenas à rede pública. É necessário criar mecanismos que facilitem o acesso e a adesão desse grupo etário à rotina preventiva ginecológica.

A partir de um questionário contendo sete perguntas, foram analisados 2585 discentes vinculados a 1ª e 3ª série de doze escolas da cidade. Na análise dos dados foram usadas média, erro padrão, teste t de student e análise de variância. Na opinião dos discentes a EA não é abordada com frequência nas disciplinas, apesar de considerarem que seus professores são, na maioria dos casos, aptos para ensinar o tema. Os alunos das escolas privadas obtiveram as melhores notas (75% de acertos e um avanço significativo de conhecimento em EA entre a 1ª e a 3ª série. O mesmo não ocorre nas escolas públicas, demonstrando uma estagnação de conhecimento nesta área ao longo do ensino médio. Os alunos das escolas estaduais acertaram, em média, 73% das questões, enquanto que na rede federal de ensino estes acertaram 67%. O avanço no conhecimento ambiental ao longo da permanência do discente no ensino médio deveria ser melhorado nas escolas, principalmente nas públicas, considerando o aspecto genérico das perguntas do questionário. O fato preocupante foi observar que nas escolas públicas não há avanço de conhecimento nesta área entre a 1ª e a 3ª série. Portanto, é necessária uma abordagem mais efetiva nas práticas desenvolvidas no ambiente escolar relativas as questões ambientais.

    Full Text Available A Região Oceânica do município de Niterói (RJ tem sido objeto de intensa especulação imobiliária nas últimas décadas, associando o ideário de paisagens naturais e qualidade de vida a um modelo de habitações predominantemente voltado para população de alto padrão aquisitivo. Neste sentido, este trabalho objetiva analisar a expansão tanto do perímetro urbano como da densidade de domicílios da região no período entre 1976 e 2010, associando ainda a situação atual com o zoneamento urbano-ambiental vigente. A análise histórica, a geoestatística e um conjunto variado de geotecnologias foram as principais ferramentas utilizadas para produção e análise de dados. Em conjunto com estas ferramentas, é proposta uma metodologia alternativa de tratamento de dados censitários e avaliação de densidades de domicílios por unidade de área. Os resultados demonstram o crescimento de 112% da área urbanizada da Região Oceânica, enquanto o número de domicílios cresceu na ordem de 600%, remontando ao processo interligado de avanço tanto via expansão em área quanto via aumento de densidade. Em comparação com o zoneamento, há esgotamento para incorporação de novas áreas perimetrais, o que aponta para um aprofundamento ainda maior do aumento de densidades demográficas nas próximas décadas assim como da pressão sobre os geossistemas costeiros.

    Full Text Available Propolis and royal jelly (RJ, two important honeybee products, have been used commonly all over the World as traditional and ethnopharmacological nutrients since ancient times. Both of them have a lot of active ingredients, which are known to be effective for several medical conditions. In this article, medical databases were searched for the usage of RJ and propolis in upper respiratory tract infections (URTI and as a dietary supplementation, together and separately. 10-hydroxy-2-decenoic acid (10-HDA is the most prominent active compound showing antimicrobial effect within RJ. Caffeic acid phenethyl ester (CAPE is the most famous one that shows antimicrobial and anti-inflammatory effect within propolis. When compared with propolis, RJ was found to have richer content for all three main nutrients; proteins, carbohydrates, and lipids. More clinical, experimental, and basic studies are needed to find out the best-standardized mixture to cope with URTI in which RJ and propolis will be main ingredients in addition to the other secondary compounds that have health-beneficial effects.

    The protective effect of Royal Jelly (RJ) against the hemopoietic dysfunction in whole body X-irradiated C57BL/6 mice was investigated. When RJ (1.0 g/kg, po or 0.5 g/kg, ip) was administered every day beginning two weeks before X-irradiation (10 Gy), a significant increase in the number of leukocytes and erythrocytes was observed in mice treated with RJ, as compared with X-irradiated control. In addition, the number of colony forming units in culture (CFU-C) of bone marrow cells or splenocytes was significantly increased in mice treated with RJ. Therefore, when granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) in peripheral blood was measured by ELISA kit, a significant increase in the amount of GM-CSF and IL-3 was observed. These results suggest that the protective effect of RJ against hemopoietic dysfunction could be expressed through an increase in the number of hemopoietic stem cells by the induction of hemopoietic factor such as GM-CSF and IL-3.

    Background Dry eye is a multifactorial disease characterized by ocular discomfort and visual impairment. Lacrimal gland function has been shown to decrease with aging, a known potent risk factor for dry eye. We have previously found that orally administrated royal jelly (RJ) restored tear secretion in a rat model of dry eye. Methods and Findings We examined the effects of RJ oral administration on dry eye in this prospective, randomized, double-blind, placebo-controlled study. Forty-three Japanese patients aged 20–60 years with subjective dry eye symptoms were randomized to an RJ group (1200 mg/tablet, six tablets daily) or a placebo group for 8 weeks. Keratoconjunctival epithelial damage, tear film break-up time, tear secretion volume, meibum grade, biochemical data, and subjective dry eye symptoms based on a questionnaire were investigated at baseline, and at 4 and 8 weeks after intervention. Adverse events were reported via medical interviews. In the RJ group, tear volume significantly increased after intervention (p = 0.0009). In particular, patients with a baseline Schirmer value of ≤10 mm showed a significant increase compared with baseline volume (p = 0.0005) and volume in the placebo group (p = 0.0051). No adverse events were reported. We also investigated the effect of RJ (300 mg/kg per day) administration using a mouse model of dry eye. Orally repeated administration of RJ preserved tear secretion, potentially through direct activation of the secretory function of the lacrimal glands. Conclusion Our results suggest that RJ improves tear volume in patients with dry eye.

    In an influential article of 1952, Thomas Kuhn argued that Robert Boyle had little or no influence on the subsequent development of chemistry. This essay challenges Kuhn's view on two fronts. First, it shows that Johann Joachim Becher developed his hierarchical matter theory under the influence of Boyle and then transmitted it to the founder of the phlogiston theory, G. E. Stahl. Second, this essay argues that transmutational matter theories were not necessarily opposed to the existence of stable chemical species, pace Kuhn. Boyle's corpuscular theory descended largely from the tradition of "chymical atomism," which often advocated both chrysopoeia and the reality of robust chemical substances.

Para a pesquisa de Campylobacter, amostras de esmegma foram coletadas e submetidas à técnica de cultivo e isolamento e amostras de lavado prepucial ao teste de Imunofluorescência Direta (IFD. Para a pesquisa de Tritrichomonas, foi utilizada a técnica de exame direto a partir de lavado prepucial. Foi observada a presença de C. fetus em 14 amostras (35,9 %, por meio da IFD, e o isolamento de C. fetus, subespécie venerealis, foi obtido a partir de quatro amostras (10,3%. T. foetus não foi identificado nas amostras investigadas. A alta freqüência de C. fetus observada nos animais investigados sugere a presença da campilobacteriose na região do Médio Paraíba, em rebanhos com problemas reprodutivos.Thirty nine breeding bulls from dairy farms (n=9 and beef farms (n=30 located in Médio Paraíba region at Rio de Janeiro - Brazil state were investigated for the presence of Campylobacter fetus and Tritrichomonas foetus. For Campylobacter investigation, smegma samples were examined by culture and prepucial washings were examined by direct immunofluorescence technique (DIF. The prepucial washings were also examined for Tritrichomonas foetus presence by direct examination. C. fetus was identified in 14 samples (35.9 % by DIF technique and C. fetus subspecies venerealis was isolated from four samples (10.3%. T. foetus was not detected in bull samples. The high frequency of C. fetus observed in bull samples suggests the occurrence of Campylobacteriosis among herds which have reproductive problems at the Médio Paraíba region.

    The objective was to compare the effects of royal jelly (RJ) and eCG treatments on reproductive performance of ewes synchronized using intravaginal progesterone-releasing devices. Forty-two cycling Awassi ewes were treated intramuscularly (i.m.) with 15 mg PGF2alpha. On the following day, all ewes were administered with CIDR-G for 12 days and were randomly allocated to three (RJ, eCG and control) groups of 14 ewes each. Ewes in the RJ-treated group received daily i.m. treatments of 400mg RJ during the period of CIDR-treatment. Each ewe in the eCG-treated group received an i.m. treatment of 500 IU eCG at the time of CIDR-G removal (day 0) and no further treatment was given to ewes in the control group. Ewes were exposed to four fertile rams for 72 h, from the time of CIDR-G removal, and checked for breeding marks at 6-h intervals. Blood samples were collected from day -13 until day 0 and thereafter until day 19 for progesterone analysis. Royal jelly treatment resulted in a greater rate of decline and lower (Pprogesterone concentrations between days -10 and 0 than eCG-treated and control ewes. Expression of estrus was similar among the three groups and intervals to onset of estrus were shorter (P<0.01) in RJ-treated (31.3h) and eCG-treated (29.8h) than control (41.3h) ewes. First-cycle pregnancy and lambing rates were greater (P<0.05) in RJ-treated (71.4 and 71.4%) and eCG-treated (85.7 and 78.6%) than in control (42.9 and 35.7%) ewes, respectively. Results demonstrate that the treatments of RJ and eCG in conjunction with CIDR-G were similarly effective in induction of estrus and improvement of pregnancy and lambing rates.

    Full Text Available ABSTRACT: Highland environments favor accumulation and preservation of soil organic matter (SOM due to low temperatures, leading to the formation of Histosols. The Itatiaia National Park (INP, Rio de Janeiro, Brazil, offers conditions for preservation of SOM deposited over time, which has led to the formation of these soils. The objective of this study was to characterize Histosols in this environment, with the premise that it may provide evidence of changes in vegetation. Organossolos (Histosols were sampled, characterized, described, and analyzed for their properties, stable isotopes of 12C and 13 14 15 14 C, N and N, and dating of organic matter through C. The soils were classified in the Brazilian Soil Classification System as Organossolo Háplico Hêmico típico - RJ-01 (Haplohemists and Organossolo Fólico Sáprico cambissólico - RJ-02 (Udifolists. The morphological properties, degree of transformation, and chemical fractioning of SOM were consistent with hemic and sapric materials. The δ13C and δ15N isotopic analyses showed a difference in the contribution of plant materials. In RJ-01, there was previous influence of algae, due to poor drainage, and depletion of δ13C, suggesting a mix of C3 and C4 plants. RJ-02 showed influence of C3 type plants. The 14C dating for RJ-01 was 3280±80 years, and for RJ-02, 2005±5 years (modern age.

    Full Text Available Abstract Background Vascular endothelial growth factor (VEGF is a key regulator of pathogenic angiogenesis in diseases such as cancer and diabetic retinopathy. Bee products [royal jelly (RJ, bee pollen, and Chinese red propolis] from the honeybee, Apis mellifera, have been used as traditional health foods for centuries. The aim of this study was to investigate the anti-angiogenic effects of bee products using human umbilical vein endothelial cells (HUVECs. Methods In an in vitro tube formation assay, HUVECs and fibroblast cells were incubated for 14 days with VEGF and various concentrations of bee products [RJ, ethanol extract of bee pollen, ethanol extract of Chinese red propolis and its constituent, caffeic acid phenethyl ester (CAPE]. To clarify the mechanism of in vitro angiogenesis, HUVEC proliferation and migration were induced by VEGF with or without various concentrations of RJ, bee pollen, Chinese red propolis, and CAPE. Results RJ, bee pollen, Chinese red propolis, and CAPE significantly suppressed VEGF-induced in vitro tube formation in the descending order: CAPE > Chinese red propolis >> bee pollen > RJ. RJ and Chinese red propolis suppressed both VEGF-induced HUVEC proliferation and migration. In contrast, bee pollen and CAPE suppressed only the proliferation. Conclusion Among the bee products, Chinese red propolis and CAPE in particular showed strong suppressive effects against VEGF-induced angiogenesis. These findings indicate that Chinese red propolis and CAPE may have potential as preventive and therapeutic agents against angiogenesis-related human diseases.

    Full Text Available The objective of the present study was to investigate selected trace and mineral elements in Royal Jelly (RJ from Bulgaria. A total of 30 RJ samples were included in the study. The analytical procedure consisted of the microwave digestion of the RJ samples with nitric acid followed by instrumental measurement. Concentrations of Al, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, P, Sr and Zn were determined using inductively coupled plasma optical emission spectroscopy (ICP-OES, while As, Cd, Co, Ni and Pb were determined by electrothermal atomic absorption spectrometry (ETAAS. Our results showed that elements K, Mg, Ca represented 96% from the total mineral content of the RJ samples from Bulgaria, while the most abundant trace element was Na, followed by Zn. The elements Ba, Cr, Cu, Fe, Mn and Sr were found in trace concentration levels and elements As, Pb, Cd, Co and Ni in microconcentration levels. Selected mineral and trace elements were found in relatively constant concentration levels in all of the analyzed RJ samples. It was concluded that chemical element content did not depend on geographical origin and was under homeostatic adjustment in RJs.

    In vitro interaction of benthic algae from the Angra dos Reis region, R.J., Brazil, was studied with critical radionuclides to be released in the liquid effluent of CNAAA (unit I). 137 Cs- 60 Co - and 125 I uptake and loss by Sargassum filipendula, Padina Vickersiae and Acanthophora Spicifera were observed. Biological half-lives and bioaccumulation factors (B.F.) were estimated. Co and I uptake were fast (apparent equilibrium in 3 to 7 days). Cs uptake was slower (2 to 3 weeks). Loss followed an inverse pattern (fast for Cs, slow for Co and I). B.F. ranged from 10 1 for Cs, to 10 3 for I and 10 3 -10 4 for Co. Higher B.F. for Co and I were found for P. vickersiae (up to 1,4 X 10 4 ) an A. spicifera (up to 7 X 10 3 ) respectively. These species represent important potential media for the transference of Co-I-and-to a much lesser extent - Cs isotopes, through food-webs. They exhibited high capacity to compete with local sandy sediments for the retention of Co and I. High B.F., rapid uptake and moderate to long biological half-lives enable S. filipendula, P. vickersiae and A. specifera to be powerful aids in the monitoring of radioactive contamination by Co and I isotopes. Since the majority of marine organisms tends to exhibit Cs B.F. similars to those reported here, these algae may also be used as monitors for Cs isotopes, the low B.F. being compensated by their abundance, wide distribution and facility of collection.

    Full Text Available Os problemas de inundações no município de São Gonçalo (RJ são cada vez mais comuns. Esta realidade é favorecida pelas condições geográficas do município somadas à intensa ocupação urbana. O agravamento das inundações também pode estar relacionado ao nível de percepção e compreensão da população em relação ao funcionamento de rios e bacias hidrográficas. O desconhecimento da dinâmica ambiental atinge também as escolas, onde o conceito de bacia hidrográfica não está sendo devidamente repassado e discutido dentro de ações de Educação Ambiental. Diante deste quadro, o presente trabalho se propôs a investigar a percepção ambiental em relação aos rios e bacias hidrográficas urbanizadas, de alunos do Ensino Básico de escolas públicas situadas em duas bacias hidrográficas que apresentam intensa degradação e descaracterização de seus rios. Para tanto, 80 estudantes foram entrevistados, percebendo-se que os mesmos não possuem conhecimento sistematizado acerca das bacias hidrográficas, o que contribui para o pouco compromisso com a preservação ambiental. A execução dessa proposta de pesquisa permitiu uma reflexão sobre as formas de abordagem do conteúdo escolar sobre rios e bacias hidrográficas.

    Full Text Available The aim of this study was to evaluate litter input and decomposition and root biomass of three forest fragments at different successional stages (advanced, medium and initial in Pinheiral Municipality, in the state of RJ, Brazil. To evaluate litter input, 10 conic collectors were installed in each fragment. The root biomass was quantified by monolith method in two periods (wet and dry at depths of 0-10, 10-20 and 20- 30 cm, and 10 samples were collected in each area. To evaluate the decomposition rate in each area, 12 litter bags were distributed. No significant differences were observed for litter input between the areas, but there was a tendency to increase litter input with successional evolution. No significant differences were observed for seasonal litter input between areas during the year, but there was a small increase in the months of July and August. At the advanced stage, litter input could be grouped into two periods: February to July, with lower values; and August to January, with higher values. The leaf fractions and reproductive material input were reduced, while branch and other fractions increased with succession. For litter decomposition, the intermediate stage showed the lowest decomposition constant (k (0.0038 g g -1day-1 and the highest half life time (182 days , followed by the initial (0044 g g -1day-1 and 154 days and advanced (0.0064 g g -1day-1 and 108 days stages. The root biomass in different areas and depths for both two periods studied showed higher values in the advanced stage, followed by the intermediate stage and the lowest values were found in the initial stage. The seasonal root biomass difference occurred mainly in the intermediate stage, with higher values in June.

    We present an empirical model of the energetic electron environment in Jupiter's magnetosphere that we have named the Galileo Interim Radiation Electron Model version-2 (GIRE2) since it is based on Galileo data from the Energetic Particle Detector (EPD). Inside 8RJ, GIRE2 adopts the previously existing model of Divine and Garrett because this region was well sampled by the Pioneer and Voyager spacecraft but poorly covered by Galileo. Outside of 8RJ, the model is based on 10 min averages of Galileo EPD data as well as on measurements from the Geiger Tube Telescope on board the Pioneer spacecraft. In the inner magnetosphere the field configuration is dipolar, while in the outer magnetosphere it presents a disk-like structure. The gradual transition between these two behaviors is centered at about 17RJ. GIRE2 distinguishes between the two different regions characterized by these two magnetic field topologies. Specifically, GIRE2 consists of an inner trapped omnidirectional model between 8 to 17RJ that smoothly joins onto the original Divine and Garrett model inside 8RJ and onto a GIRE2 plasma sheet model at large radial distances. The model provides a complete picture of the high-energy electron environment in the Jovian magnetosphere from ˜1 to 50RJ. The present manuscript describes in great detail the data sets, formulation, and fittings used in the model and provides a discussion of the predicted high-energy electron fluxes as a function of energy and radial distance from the planet.

The SE program consisted of the elbow-toe, hand-knee, and back bridge, and the CE program consisted of the sit-up, sit-up with trunk rotation and back extension. Testing of a countermovement jump (CMJ) and rebound jump (RJ) were performed to assess jump performance. Jump height of the CMJ and RJ-index, contact time, and jump height of the RJ were analyzed. The RJ index was improved significantly only after SE (p=0.017). However, contact time and jump height did not improve significantly in the SE condition. Moreover, no significant interaction or main effects of time or group were observed in the CMJ. Consequently, this study showed the different immediate effect on the RJ between the SE and CE, and suggested the possibility that the SE used in this study is useful as a warm-up program to improve the explosive movements. © Georg Thieme Verlag KG Stuttgart · New York.

    To illustrate, through internal industry documents, how RJ Reynolds exploited the concerns of the Japanese society about cleanliness to market the concept of cleaner, implicitly healthier cigarettes in Japan. Systematic keyword and opportunistic website searches of formerly private internal industry documents. Industry documents show that RJ Reynolds developed marketing plans based upon their cultural assumptions of Japanese people as fastidious about hygiene and manners, and with relatively high penchants to try new products. RJ Reynolds found there was also a growing concern for health, the environment, and smokers were conscious about annoying others. Deodorised consumer products were one of Japan's biggest trends. These characteristics presented RJ Reynolds with a profitable formula for marketing Salem Pianissimo, a clean cigarette with less smell and smoke. Salem Pianissimo, a 100 mm cigarette claiming to contain 1 mg tar and 0.1 mg nicotine, targeted women since menthol cigarettes were popular among 18-24 year old female smokers, although Japan's law prohibited those below 20 years to smoke and the tobacco industry had a voluntary code disallowing advertising to women and youth. RJ Reynolds successfully launched its clean cigarette, Salem Pianissimo, in Japan aiming to exploit perceived cultural characteristics such as a penchant for cleanliness, an eagerness to try new products, and social harmony.

    Full Text Available OBJETIVO: verificar a prevalência de obesidade entre adultos das 86 famílias agricultoras de um bairro de Petrópolis, RJ, e analisar seus determinantes socioculturais. MÉTODOS: estudo quantitativo e qualitativo sobre nutrição, práticas alimentares e de trabalho realizado em 2008. Dados antropométricos foram coletados por inquérito nutricional domiciliar e o material qualitativo por observação participante e entrevistas. RESULTADOS: a prevalência de obesidade foi baixa (9,3% entre os homens, mas bastante elevada entre as mulheres (29,9%. A prática agrícola local implica em atividade física leve para mulheres e intensa para homens. Essa diferença não é acompanhada na dieta, semelhante para homens e mulheres, com predomínio de alimentos de alto valor calórico. A produção familiar objetiva essencialmente a venda. A agricultura mercantil e a decorrente especialização dos cultivos favorecem comprar alimentos no mercado em vez de produzir para autoconsumo. CONCLUSÃO: os aspectos socioculturais e ocupacionais estudados podem ter contribuído para elevar a prevalência de obesidade nas mulheres e podem ser úteis no estudo de outros grupos com características semelhantes. Esta pesquisa ratifica a importância de estudar a obesidade em nível local, integrando abordagens quantitativas e qualitativas para identificar possíveis limitações e portas de entrada para ações de intervenção localmente relevantes.

    Restorative justice (RJ) programs have become widespread in the United States and in other countries. These programs are often seen as a viable alternative to traditional retributive processing, especially for minor, and sometimes more serious, forms of delinquency and adult criminality. The programs hold promise for achieving several goals, including increased community and victim involvement, greater satisfaction with the case outcomes, improved offender compliance, increased perceptions of fairness, and even recidivism reduction. Meta-analyses have demonstrated varying degrees of program success in recidivism reduction, which may in part reflect differential effectiveness of the RJ approach for various kinds of offenders. This study examined whether an RJ program for juvenile offenders had differential impacts on recidivism across various offender characteristics (including age, gender, racial group, offending history, and current offense). Results generally support the effectiveness of the program for many types of offenders. Implications for future research and potential improvements to the RJ model are discussed.

    The present study was undertaken to investigate the protective effect of royal jelly (RJ) against toxicity induced by a synthetic pyrethroid insecticide, lambda-cyhalothrin (LCT), in Swiss albino mice. Animals were randomly divided into six groups of six animals each. The control group received distilled water alone, whereas mice in the treatment groups received RJ alone (100 or 250 mg/kg of body weight), LCT alone (668 ppm), or RJ+LCT for 21 days. All mice (100%) survived until the end of experiment and were sacrificed at the end of 24 hours. Blood, bone marrow, and liver and kidney tissues were analyzed for aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), and reduced glutathione (GSH) levels and micronucleus (MN) frequency, chromosomal aberrations (CAs), and pathological damages. Serum AST, ALT, BUN, and creatinine levels were elevated in mice treated with LCT alone compared with the other tested groups (P<.05). LCT-induced oxidative damage caused a significant decrease in GSH levels and a significant rise in MDA levels of liver and kidney tissues. LCT alone-treated mice presented higher frequencies (P<.05) of MNs, CAs, and abnormal metaphases compared with the controls; moreover, the mitotic index was lower than in controls (P<.05). Oral treatment with RJ significantly ameliorated the indices of hepatotoxicity, nephrotoxicity, lipid peroxidation, and genotoxicity induced by LCT. Both doses of RJ tested provided significant protection against LCT-induced toxicity, and its strongest effect was observed at the dose level of 250 mg/kg of body weight. In vivo results suggest that RJ is a potent antioxidant against LCT-induced toxicity, and its protective effect is dose dependent.

    Among royal jelly's (RJ) various biological activities, its possible antitumour activity deserves particular attention. The purpose of this study was to investigate the influence of RJ, its bioactive component 10-hydroxy-2-decenoic acid (10- HDA), and human interferon-alpha (HuIFN-αN3) on the proliferation of human colorectal adenocarcinoma cells (CaCo- 2), and ascertain their effect on intracellular glutathione (GSH) level and lipid peroxidation. We studied the antiproliferative (AP) activity of RJ [(0.1 g/10 mL phosphate buffer saline (PBS)], HuIFN-αN3 (1000 I.U. mL⁻¹), 10-HDA at 100.0 μmol L⁻¹, and their different combinations, in the ratio 1:1, 1:2, and 2:1 on CaCo-2 cells. The GSH level was measured by glutathione assay. The lipid peroxidation was measured by malondialdehyde (MDA) assay. Single RJ had a low AP activity: 2.0 (0.5 mg mL⁻¹). HuIFN-αN3 had an AP activity of 2.5 (208.33 I.U. mL⁻¹), while 10-HDA had an AP activity of 1.5 (37.5 μmol mL⁻¹). The highest AP activity of 3.8 was obtained when RJ and HuIFN-αN3 were applied at the ratio 2:1. In that combination the level of GSH was 24.9±2.4 nmol g⁻³ of proteins (vs. 70.2±3.2 nmol g⁻³ in the control) and the level of MDA was 72.3±3.1 nmol g⁻³ (vs. 23.6±9.1 nmol g⁻³ in the control). It is generally assumed that 10-HDA, an important constituent of RJ, together with HuIFN-αN3, is responsible for the inhibition of CaCo-2 cells proliferation in vitro. In our study, however, RJ and HuIFN-αN3 applied at 2:1 decreased the level of GSH the most and significantly increased lipid peroxidation via MDA in CaCo-2 cells. Future studies should show whether these GSH- and MDA-related activities of RJ, HuIFN-αN3, 10-HDA, and their combinations may decrease the tumorigenicity index and tumorigenic potential of various tumour cells in vitro.

    We measure basic network parameters of silvernanowire (AgNW) networks commonly used as transparent conductingelectrodes in organic optoelectronic devices. By means of four point probing with nanoprobes, the wire-to-wire junction resistance and the resistance of single nanowires are measured. The resistanceRNW of a single nanowire shows a value of RNW=(4.96±0.18) Ω/μm. The junction resistanceRJ differs for annealed and non-annealed NW networks, exhibiting values of RJ=(25.2±1.9) Ω (annealed) and RJ=(529±239) Ω (non-annealed), respectively. Our simulation achieves a good agreement between the measured network parameters and the sheet resistanceRS of the entire network. Extrapolating RJ to zero, our study show that we are close to the electrical limit of the conductivity of our AgNW system: We obtain a possible RS reduction by only ≈20% (common RS≈10 Ω/sq). Therefore, we expect further performance improvements in AgNW systems mainly by increasing NW length or by utilizing novel network geometries.

    Full Text Available Symptoms of depression and anxiety appeared in mice after they had been subjected to a combination of forced swimming for 15 min followed by being kept in cages that were sequentially subjected to leaning, drenching, and rotation within 1-2 days for a total of 3 weeks. The animals were then evaluated by the tail-suspension test, elevated plus-maze test, and open-field test at 1 day after the end of stress exposure. Using these experimental systems, we found that 10-hydroxy-trans-2-decenoic acid (HDEA, an unsaturated fatty acid unique to royal jelly (RJ, protected against the depression and anxiety when intraperitoneally administered once a day for 3 weeks simultaneously with the stress loading. Intraperitoneally administered RJ, a rich source of HDEA, was also protective against the depression, but RJ given by the oral route was less effective. Our present results demonstrate that HDEA and RJ, a natural source of it, were effective in ameliorating the stress-inducible symptoms of depression and anxiety.

  1. Resistance to the mainlandization of criminal justice practices: a barrier to the development of restorative justice in Hong Kong.

    Lo, T Wing

    2012-06-01

    This article examines the political and legal barriers to introducing restorative justice (RJ) in Hong Kong. It argues that the processes involved in RJ may be in conflict with the rule of law, which is regarded by the citizens of Hong Kong as sacrosanct in their resistance to the "mainlandization" of criminal justice practices after China resumed sovereignty of Hong Kong. It is argued that, because it could admit such potentially harmful Chinese criminal justice concepts as "rule by the people," "absence of the presumption of innocence," "leniency for self-confession and severity for resistance," and "toeing the party line," RJ would be devoid of any restorative substance and could breach the principles of due process.

    Full Text Available Epilepsy is one of the most common neurological diseases affecting at least 50 million people worldwide. Valproic acid (VPA is a widely used antiepileptic medication for both generalized and partial seizures of epilepsy. The objective of the study was to investigate the anti-mutagenic and anti-histopathologic effects of royal jelly (RJ on VPA-induced genotoxicity and nephrotoxicity in male albino mice (Mus musculus. 80 Mice were used for 21 days; they were divided into eight groups, (G1 served as normal control group, G2 received VPA (100 mg/kg and (G3–G5 received RJ at doses 50, 100 and 200 mg/kg respectively. While (G6–G8 were administrated RJ simultaneously with VPA. In RJ treated mice at doses of 50 and 100 mg/kg, the kidney sections showed normal histological structure with non significant changes in chromosomal aberrations (CA and mitotic index (MI, while RJ at dose of 200 mg/kg showed mild inflammatory cells infiltration and hyperemic glomeruli but not highly significant changes in CA and MI. The cortex of VPA treated mice revealed congested glomeruli with inflammatory cells infiltration, and marked degeneration of almost structures of the glomeruli including some vacuoles in mesangial cells with dark mesangial substances on the ultrastructure level. Some proximal tubules showed degeneration of microvilli on the apical parts of some cells. Cells of the distal tubules attained obliterated lumen and vacuolated lining epithelium. The results also revealed that valproic acid induced a high frequency of CA in bone marrow cells of mice and MI was significantly decreased indicating bone marrow cytotoxicity. The treatment of mice with RJ at doses 50, 100 and 200 mg/kg for 21 days simultaneously with VPA resulted in abating the histological alterations in renal tissues with significant reduction in chromosomal aberrations, for doses of 50 and 100 mg/kg, and elevation in mitotic index (P < 0.05. RJ at doses 50 and 100 mg/kg appeared

    Studies around the management and disposal of radioactive waste have been conducted for decades. In Brazil, the National Nuclear Energy Commission (CNEN) is responsible for Intermediate Radioactive Waste deposits, located in Fundao Island, Rio de Janeiro (RJ). According to CNEN 8.01 norm, it is necessary to characterize and to study the location area around the deposit. Within this context, the objective of this study was to characterize the Canal Cunha Basin, the western of Guanabara Bay and study the Environmental Impact, with determination of heavy metals (Pb, Cu, Cd, Zn and Ni) in said river basin and bay. The work involves collecting water and sediment samples in five georeferenced points. The sediment samples was collected using the EPA Method 3051 and the reading of the concentrations of heavy metals in water and sediment was performed by ICP-OES. Maps were generated for characterization and spatial distribution of these metals on Canal Cunha Basin. The Canal Cunha's drainage composes a territory with 62.85 km 2 (approximated area) and 37.01 km of perimeter The high occupancy rates in the urban area that decrease the rate of infiltration and changes in physiography caused by construction of embankments because a reverse behavior expected, which increases the runoff coefficient of 0.74. The results show that in periods of high river discharge, there is a drift of large amounts of Pb, Cu and Cd to the waters of the Canal Cunha and Guanabara Bay. Zn and Ni presented higher concentrations in the dry season. The Pb, Cu, Cd, Zn and Ni concentrations are smaller than the concentrations found in the sediment. This probably happens because Cunha Canal Basin and western of Guanabara Bay receive high organic load, and also because of the high percentage of fine sediment in this, thus promoting the adsorption of metals, not contaminating the water and thus not reaching the food chain.

    2016-01-01

    Full Text Available Background and Objectives: Phenylhydrazine (PHZ, as a known hemolytic agent, causes toxicity in different tissues at various levels. The aim of the current study was to examine the possible protective effects of royal jelly (RJ against PHZ-induced histological injuries of small intestine in mice.   Methods: In this experimental study, adult male mice were randomly divided into four groups of 8 mice each. PHZ was administered intraperitoneally to two groups of mice (at a dose of 60mg/kg every 48 hours for 35 days. One of the groups received RJ (100mg/kg orally 4 hours before PHZ administration. The third group only received RJ, and the forth group was considered as control. Twenty-four hours after the last treatment, different segments of small intestine were dissected out, then histological sections were prepared and quantitative morphometric assessments were performed. To compare the groups, one-way ANOVA and multiple comparative Tukey tests were used. The significance level was considered to be p<0.05.   Results: In this study, PHZ caused significant decreases in depth of duodenal crypts, distribution rate of the goblet cells in ileal villi, width of duodenal and jejunal villi, and height of villi in all three segments of small intestine. Co-administration of RJ partially improved the changes in the above parameters.   Conclusion: From results of this study, it seems that RJ as a free radical scavenger could reduce PHZ-induced intestinal toxicity in mouse.

    Full Text Available Royal jelly (RJ is used as a revitalizing tonic. In order to avoid rejection to its acid taste, it is added to honey. There are regulations for honey and for royal jelly separately but not for the mixture. The objective of this work is, therefore, to verify if the same methods used for pure honey quality control can be used for honey mixed with royal jelly and also the presence of RJ through 10-HDA determination. The methods used were: moisture, reducing sugars, apparent sucrose, ash, hydroxymethylfurfural, insoluble solids, diastase activity, acidity and 10-HDA. Samples were prepared by adding 0-100% of RJ in honey. The results showed that the ash method was the only suitable one to all the samples. The acidity analysis (direct titration was suitable to 0-30%RJ samples; the reducing sugar analysis was suitable to 0-20% RJ samples. Concerning moisture analysis the refractometric method is suitable to 0-10% RJ and the Infra Red method is suggested to be used for samples with more than 10% RJ. The methods for diastase activity, HMF, apparent sucrose and insoluble solids were inadequate for all samples with RJ. The presence of RJ in the samples was confirmed by the 10-HDA analyses.A geléia real (GR é utilizada como produto revitalizante com sabor ácido e adstringente. Para evitar rejeição a este sabor, existem misturas de mel com GR. Existe legislação específica para o mel e para a GR separadamente, mas não para a mistura. Os objetivos do trabalho são: verificar se os métodos usados para o controle de qualidade do mel puro podem ser utilizados no controle do mel com GR e verificar a presença de GR pela determinação do 10-HDA. As análises incluíram: umidade, açúcares redutores, sacarose aparente, cinzas, hydroxymethylfurfural, sólidos insolúveis, atividade diastásica, acidez e 10-HDA. As amostras foram preparadas com 0-100% de GR no mel. Os resultados obtidos sugerem que dos métodos citados na legislação do mel somente o de

Do total de entrevistados, 83,3%, afirmou acreditar no potencial dos medicamentos à base de plantas medicinais e apoia o uso destes medicamentos, mas a maioria, 94,4%, diz não conhecer o programa, que é exatamente o que regulamenta o uso de plantas medicinais, e possui um “banco de dados” das plantas que tem sua “confiabilidade” verificada. O fato de a maioria dos médicos não terem conhecimento sobre o programa nacional de plantas medicinais, é algo preocupante, pois foi possível perceber na realização desta pesquisa, que alguns consideram o uso de plantas, ou de medicamentos à base de plantas medicinais uma forma de tratamento com menos efeitos colaterais, porém esta falta de informação sobre o programa não garante uma relação risco-benefício favorável. Assim, é de total importância que médicos formados e acadêmicos conheçam o programa nacional de plantas medicinais para uma possível implantação de programas que incentivem o de tratamentos à base de plantas medicinais pelo SUS como uma alternativa mais viável.

    Full Text Available Neste artigo, analisamos o movimento de um grupo de Ação Solidária denominado Associação Brasileira de Expostos ao Amianto do Rio de Janeiro (ABREA/RJ. Privilegiamos a fala e o ponto de vista dos próprios trabalhadores sobre o movimento, com base no enfoque dos estudos qualitativos e da investigação participativa. Sob a égide do método da educação popular, realizamos reuniões de grupo pautadas na colaboração entre trabalhadores e pesquisadores, o que se mostrou uma estratégia pedagógica facilitadora da reconstrução dos vínculos de solidariedade e da promoção da saúde. Desenvolvemos o argumento de que as práticas de educação em saúde, relativas ao mundo do trabalho, exigem socialização das informações e do conhecimento científico, aliadas a uma ação política integrada que potencialize transformações a favor de uma cidadania plena no trabalho. Outrossim, sustentamos o caráter imprescindível de alguns elementos para a concretização, a contento, de uma práxis educativa em saúde dos trabalhadores, a saber: participação, diálogo, solidariedade e aliança entre trabalhadores e pesquisadores. Por fim, enfatizamos o valor das redes - nas esferas nacional e internacional - de apoio aos trabalhadores no fortalecimento do movimento de banimento do amianto, como também o fato de o próprio trabalho ser um importante ativador da organização de luta pela saúde.In this article we analyze the movement of a solidarity action group named Brazilian Association of the Exposed to Asbestos of Rio de Janeiro (ABREA/RJ.

    Full Text Available Trans-10-hydroxy-2-decenoic acid (10-H2DA, 10-hydroxydecanoic acid (10-HDAA, and sebacic acid (SEA are the three major fatty acids in royal jelly (RJ. Previous studies have revealed several pharmacological activities of 10-H2DA and 10-HDAA, although the anti-inflammatory effects and underlying mechanisms by which SEA acts are poorly understood. In the present study, we evaluated and compared the in vitro anti-inflammatory effects of these RJ fatty acids in lipopolysaccharide-stimulated RAW 264.7 macrophages. The results showed that 10-H2DA, 10-HDAA, and SEA had potent, dose-dependent inhibitory effects on the release of the major inflammatory-mediators, nitric oxide, and interleukin-10, and only SEA decreased TNF-α production. Several key inflammatory genes have also been modulated by these RJ fatty acids, with 10-H2DA showing distinct modulating effects as compared to the other two FAs. Furthermore, we found that these three FAs regulated several proteins involved in MAPK and NF-κB signaling pathways. Taken together, these findings provide additional references for using RJ against inflammatory diseases.

    In 2011, the mountainous region of the State of Rio de Janeiro (Brazil) suffered enormous social and economic losses due to thousands of landslides caused by an extreme rainfall event. The mapping of the scars of these landslides in an area of 421 km2 in the municipality of Nova Friburgo, RJ - Brazil resulted in a total of 3622, and 89% of these scars were located in areas covered by grasses and forests. Despite the unexpected result (64% of scars in forest areas), field evidence has shown that most of the forest fragments in the municipality are in the initial stages of succession and in different states of degradation, evidencing the need for a better understanding of the role of these forests in the detonation and propagation of landslides. Two slope forest areas with different ages (20 and 50 years) were evaluated in relation to the vegetative aspects that influence the stability of the slopes in each area. Hydrological monitoring, including precipitation, interception by manual and automatic method, soil moisture and subsurface flows were performed in two different areas: forest and grass. Soil moisture was monitored by granular matrix sensors and flows by collecting troughs in trenches at depths of 0 cm, 20 cm, 50 cm, 100 cm, 150 cm and 220 cm, which were also analyzed for biomass and length of thick roots (> 2 mm diameter) and thin roots (particle size, aggregate stability, porosity and hydraulic conductivity in situ). In the grass area, the lower soil structure in relation to the forest areas makes it difficult to transmit the water through the soil matrix. During the monitoring period, that area preserved the moisture in depths of 100 cm, 150 cm and 220 cm. The fasciculate root system of the grasses increased the infiltration of water at the top of the soil, favouring the formation of more superficial saturation zones in the heavy rains, due to the hydraulic discontinuities. In forest areas, infiltration by preferential paths allows the concentration of

Optou-se por uma pesquisa de base interpretativa, na qual se utilizou entrevista semiestruturada e análise de conteúdo em sua vertente temática. Foram incluídas 18 gestantes e oito puérperas (n=26, sendo sete adolescentes e 19 adultas; primíparas e multíparas. Para as mulheres, comer e assistir à televisão, comer fora de casa e comer com parentes e amigos no fim de semana eram formas de associar lazer à comida, aumentando o prazer por ela. A renda foi apontada como a principal barreira para o consumo de alimentos saudáveis, que era prioridade das crianças. Por esses motivos, leite, verduras, legumes e frutas eram pouco consumidos. A dieta era composta basicamente por arroz, feijão e frango. Houve preferência por "besteiras". As mulheres estavam submetidas a uma alimentação monótona. Ressalta-se a importância da compreensão e valorização das questões socioculturais e econômicas que influenciam as práticas alimentares, a fim de que a orientação alimentar e nutricional, visando à alimentação saudável, possa ser negociada e ajustada às necessidades e à subjetividade das mulheres grávidas.This study aimed to analyze the self-reported eating practices of pregnant and postpartum women living in a group of slum communities in the city of Rio de Janeiro, RJ, Brazil.

    Full Text Available In the honey bee (Apis mellifera, queen and workers have different behavior and reproductive capacity despite possessing the same genome. The primary substance that leads to this differentiation is royal jelly (RJ, which contains a range of proteins, amino acids, vitamins and nucleic acids. MicroRNA (miRNA has been found to play an important role in regulating the expression of protein-coding genes and cell biology. In this study, we characterized the miRNAs in RJ from two honey bee sister species and determined their possible effect on transcriptome in one species.We sequenced the miRNAs in RJ either from A. mellifera (RJM or A. cerana (RJC. We then determined the global transcriptomes of adult A. mellifera developed from larvae fed either with RJM (mRJM or RJC (mRJC. Finally we analyzed the target genes of those miRNA that are species specific or differentially expressed in the two honey bee species. We show that there were differences in miRNA between RJM and RJC, and that transcriptomes of adult A. mellifera were affected by the two types of RJ. A high proportion (23.3% of the affected genes were target genes of differential miRNAs.We show for the first time that there are differences in miRNAs in RJ between A. mellifera and A. cerana. Further, the differences in transcriptomes of bees reared from these two RJs might be related to miRNA differences of the two species. This study provides the first evidence that heterospecific royal jelly can modify gene expression in honey bees through an epigenetic mechanism.

    Full Text Available The present work was designed to assess the radioprotective effect of royal jelly (RJ against radiation-induced apoptosis in human peripheral blood leukocytes. In this study, peripheral blood samples were obtained on days 0, 4, 7, and 14 of the study from six healthy male volunteers taking a 1000 mg RJ capsule orally per day for 14 consecutive days. On each sampling day, all collected whole blood samples were divided into control and irradiated groups which were then exposed to the selected dose of 4 Gy X-ray. Percentage of apoptotic cells (Ap % was evaluated for all samples immediately after irradiation (Ap0 and also after a 24 h postirradiation incubation at 37°C in 5% CO2 (Ap24 by the use of neutral comet assay. Concerning Ap0, collected data demonstrated that the percentage of apoptotic cells in both control and irradiated groups did not significantly change during the study period. However, with respect to Ap24, the percentage of apoptotic cells in irradiated groups gradually reduced during the experiment, according to which a significant decrease was found after 14 days RJ consumption (P = 0.002. In conclusion, the present study revealed the protective role of 14 days RJ consumption against radiation-induced apoptosis in human peripheral blood leukocytes.

    Full Text Available Os estudos iniciais sobre a soroprevalência de anticorpos anti-VIH-1 (Ac-VIH em unidades de hemodiálise no Estado do Rio de Janeiro (RJ foram feitos em 1985. Os números alarmantes, próximos a 14%, foram atribuídos à má qualidade do sangue obtido de "doadores profissionais" em troca de comida ou dinheiro. Recentemente uma série de medidas foram adotadas na tentativa de reduzir o tráfico de sangue. Nossa investigação objetivou avaliar o impacto destas na soroprevalência de Ac-VIH em duas unidades satélites no RJ. A Clínica Segumed foi uma das unidades estudadas em 1985. Em 1987 realizamos um segundo levantamento no mesmo grupo estudado previamente. A Casa de Saúde Grajaú, inaugurada em 1986 com a maioria dos pacientes novos em diálise, foi estudada em 1988. O teste ELISA HIV-1 foi utilizado como rastreamento. Os resultados positivos foram confirmados com Western blot. Os resultados na Segumed mostraram uma grande diferença entre os dois levantamentos (14,4% vs 3,6%. Os dois casos positivos em 1987 estavam entre os identificados em 1985. Nenhum paciente se infectou entre os dois levantamentos apesar de não se utilizarem medidas de isolamento para os portadores de VIH e do uso de transfusões ter aumentado no período. Na CS Grajaú apenas dois casos foram encontrados (soroprevalência 2,4% embora um já fosse conhecido desde 1985 quando vivia com um transplante. Uma revisão de estudos semelhantes no RJ e São Paulo parece revelar uma tendência à diminuição das taxas nos últimos anos. Nós concluímos que a chance de contaminação com VIH é atualmente reduzida nos centros estudados e pode estar caindo globalmente no RJ. É possível que a maior vigilância, e até fechamento de bancos de sangue, tenha resultado na melhora da qualidade do sangue no RJ.The initial surveys on the seroprevalence of anti-HIV-1 antibodies (HIV-Ab in hemodialysis units in the State of Rio de Janeiro (RJ were done in 1985.

    Full Text Available The article analyzes four Brazilian documentaries inspired by the community studies method and structured on a collage of interviews as the final discourse. These narratives are problematic, even in terms of the interviews and the testimonies themselves. Far from being a dialogue set on stage, they reflect an attempt at transparency on the part of the filmmaker. In our opinion, this leads to serious ethical infractions, primarily because it reveals, without intermediation, the intimacy of those being interviewed. For example, it would free a couple taking advantage of the documentary, and its limited reception, of any inhibitions about expressing their disagreements.

    2003-04-01

    Measurements of the high energy, omni-directional electron environment by the Galileo spacecraft Energetic Particle Detector (EPD) were used to study the high energy electron environment in the Jovian magnetosphere, especially in the region between 8 to 18 Rj (1 Rj = 1 Jovian radius = 71,400 km). 10-minute averages of the EPD data collected between Jupiter orbit insertion (JOI) in 1995 and the orbit number 33 (I33) in 2002 form an extensive dataset, which has been extremely useful to observe temporal and spatial variability of the Jovian high energy electron environment. The count rates of the EPD electron channels (0.174, 0.304, 0.527, 1.5, 2.0, and 11 MeV) were grouped into 0.5 Rj or 0.5 L bins and analyzed statistically. The results indicate that: (1) a log-normal Gaussian distribution well describes the statistics of the high energy electron environment (for example, electron differential fluxes) in the Jovian magnetosphere, in the region studied here; (2) the high energy electron environments inferred by the Galileo EPD measurements are in a close agreement with the data obtained using the Divine model, which was developed more than 30 years ago from Pioneer 10, 11 and Voyager 1, 2 data; (3) the data are better organized when plotted against magnetic radial parameter L than Rj; (4) the standard deviations of the 0.174, 0.304, 0.527 MeV channel count rates are larger than those of the 1.5, 2.0, 11 MeV count rates in 12 Rj. These observations are very helpful to understand short- and long-term, and local variability of the Jovian high energy electron environment, and are discussed in detail.

    Full Text Available Royal jelly (RJ is a natural product which the honeybee secretes as a special diet for a queen bee. It is one of the natural products in which various functionalities, such as antibacterial effects, immunomodulating properties, and estrogen-like action, were reported. We investigated the effect of the RJ extract on the moisturizing effect by topical application in humans. The stratum corneum moisture was increased significantly after four weeks by using the RJ extract lotion compared to placebo lotion. RJ extract contained a characteristic ingredient, 10-hydroxy-2-decenoic acid (10H2DA and 10-hydroxydecanoic acid (10HDAA, etc. However, the mechanism of stratum corneum moisture and its contributing ingredient have not yet been elucidated. We have investigated the effects of 10H2DA and 10HDAA on the free amino acids content in the stratum corneum using a cultured human three-dimensional epidermis model. Additionally, the effect of 10H2DA and 10HDAA on the amounts of filaggrin (FLG and aquaporin 3 (AQP3 were investigated at the mRNA level and by immunohistochemistry using a cultured human epidermis model. It was determined that 10H2DA increases the free amino acids in the stratum corneum of the cultured human epidermis model, and that it increased FLG on both the mRNA and protein levels. On the other hand, these actions are not observed by treatment of 10HDAA. The mRNA and protein level of AQP3 did not increase with 10H2DA or 10HDAA use. It was thought that the increase in the amount of FLG and the increase in the free amino acids of the epidermis and the stratum corneum, respectively, by 10H2DA were participating in the moisturizing function of the stratum corneum by the continuous use of RJ extract lotion.

    This study is aimed to evaluate the possible neurotoxic effect of tartrazine (T), an extensively used synthetic azo dye, as well as to determine the potential modulatory role of cod liver oil (CLO) or royal jelly (RJ) against such effects. For this purpose, thirty-six male rat pups were allocated into six groups. The 1st group received distilled water (control group), the 2nd group was given 300 mg RJ/kg bw (RJ group), the 3rd group was given 0.4 ml CLO/kg bw (CLO group), the 4th was given 500 mg T/kg bw (T group). The 5th group was given T concurrently with RJ (TRJ group) and the 6th group was given T concurrently with CLO (TCLO group), at the same doses as the former groups. All treatments were given orally for 30 consecutive days. The concentrations of different brain neurotransmitters, gamma amino butyric acid (GABA), dopamine (DA) and serotonin (5HT) as well as the antioxidant and oxidative stress biomarkers were measured in the brain homogenates. An immunohistochemical staining of the cerebral cortex was applied with the anti-ssDNA antibody (an apoptotic cell marker) to reveal the changes in brain structure. The T group revealed a significant decrease in the concentration of the brain neurotransmitters, a sharp shortage in the level of antioxidant biomarkers (super oxide dismutase, catalase and the reduced glutathione), a marked increase in malondialdehyde levels, and numerous apoptotic cells in the brain cortex compared with the other groups. Interestingly, all the previously mentioned parameters were almost retrieved in both the TRJ and TCLO groups compared to the T group. These results conclusively demonstrate that RJ and CLO administration provides sufficient protection against the ruinous effects of T on rat pups brain tissue function and structure.

    This paper presents simple and relatively efficient methods to estimate some physical and chemical properties of polycyclic alkanes. These properties are melting point, normal boiling point, standard enthalpy of vaporization at 298 K, standard enthalpy of formation at 298 K, standard enthalpy of combustion at 298 K, density (specific gravity) and flash point. These methods are validated, despite the scarcity of experimental data, with several tens of polycyclic alkanes. Then the methods are used to estimate properties of some polycyclic alkanes, which are currently in use as missile fuels: JP-10, RJ-4 and RJ-5. Estimates and experimental data are found in good agreement for these fuels. This methodology is then used to evaluate missile fuel candidates to be used pure or as additive to JP-10 or to blends such as RJ-6. Several compounds are probably of interest for this task and their advantages and drawbacks are discussed. (Abstract Copyright [2006], Wiley Periodicals, Inc.)

    In this study, the proteins contained in royal jelly (RJ) produced by Africanized honeybees and European honeybees (Apis mellifera) haven been analyzed in detail and compared using two-dimensional gel electrophoresis, and the N-terminal amino acid sequence of each spot has been determined. Most spots were assigned to major royal jelly proteins (MRJPs). Remarkable differences were found in the heterogeneity of the MRJPs, in particular MRJP3, in terms of molecular weights and isoelectric points between the two species of RJ. Furthermore, during the determination of the N-terminal amino acid sequence of each spot, for the first time, MRJP4 protein has been identified, the existence of which had been only implied by cloning of its cDNA sequence. The presence of heterogeneous bands of glucose oxidase was also identified. Thus, the results suggest that two-dimensional gel electrophoresis provides a suitable method for the qualitative analysis of the proteins contained in RJ derived from different honeybee species.

    Few data are available regarding viral hepatitis perception among the general global population. The present study aims to estimate the perception of viral hepatitis in a cohort of individuals living in two geographical regions of Brazil: North (Manaus city (MA)) and Southeast (Rio de Janeiro city (RJ)). A cross-sectional, descriptive study was carried out among 287 subjects recruited in MA (134) and RJ (153). All individuals answered a questionnaire assessing socio-demographic characteristics and viral hepatitis awareness. Participants’ responses were scored and divided using interquartile values. Associations between socio-demographic characteristics and knowledge were also evaluated. Interquartile analysis scored 0–21 correct answers as “Very Weak”; 22–27 as “Weak”; 28–31 as “Intermediate”; and 32–47 as “Desirable”. Mean ± standard deviations (SD) of correct responses were weak in both MA (24.1 ± 7.0) and RJ (26.3 ± 7.3). Bivariate analysis showed an association between viral hepatitis awareness and both education level (p < 0.001) and family income (p < 0.01). Desirable scores were more common in female participants (61%), those aged between 21–30 years (40%), those with a secondary education (51.7%), those who received high income (31.6%), and those from RJ (70.0%). Health education campaigns in these cities are recommended to increase knowledge and reduce the transmission of these viruses. PMID:29364166

  14. Influence of the solar wind and IMF on Jupiter's magnetosphere: Results from global MHD simulations

    Due to its large size, rapid rotation and presence of substantial internal plasma sources, Jupiter's magnetosphere is fundamentally different from that of the Earth. How and to what extent do the external factors, such as the solar wind and interplanetary magnetic field (IMF), influence the internally-driven magnetosphere is an open question. In this work, we solve the 3D semi-relativistic magnetohydrodynamic (MHD) equations using a well-established code, BATSRUS, to model the Jovian magnetosphere and study its interaction with the solar wind. Our global model adopts a non-uniform mesh covering the region from 200 RJ upstream to 1800 RJ downstream with the inner boundary placed at a radial distance of 2.5 RJ. The Io plasma torus centered around 6 RJ is generated in our model through appropriate mass-loading terms added to the set of MHD equations. We perform systematic numerical experiments in which we vary the upstream solar wind properties to investigate the impact of solar wind events, such as interplanetary shock and IMF rotation, on the global magnetosphere. From our simulations, we extract the location of the magnetopause boundary, the bow shock and the open-closed field line boundary (OCB), and determine their dependence on the solar wind properties and the IMF orientation. For validation, we compare our simulation results, such as density, temperature and magnetic field, to published empirical models based on in-situ measurements.

    Full Text Available Royal jelly has become a high-value commercial product and the standardization of this product is required to guarantee its quality on the market. The objective of the research activity was to pursue the chemical composition of commercial samples of Royal Jelly in Romania in order to propose standardization for this product. The physico-chemical composition of commercial Royal Jelly samples was analysed by determining quality parameters like: carbohydrates, lipids, proteins, 10-hydroxy-2-decenoic acid (10-HDA and mineral elements. Carbohydrates analysis showed values between 3.4 % and 5.87 % for fructose, 4.12 % and 7.05 % for glucose, while for sucrose the values ranged between 0.95 % and 2.56 % (determined by HPLC-RI. The lipids content ranged between 1.85 % and 6.32 % (determined by the Soxhlet method. The protein values extended from 13.10 % (RJ2 to 17.04 % (RJ10 (the total protein content was determined by the Kjeldahl method. The values for the major fatty acid in Royal Jelly, 10-HDA, ranged between 1.35 % (RJ8 and 2.03 % (RJ10 (determined by high-performance liquid chromatography. The concentration of minerals varied between 3188.70 mg/kg and 4023.39 mg/kg (the concentration of minerals was measured using flame atomic absorption spectrometry. Potassium, followed by magnesium, sodium and calcium, occurs in the highest concentrations. The commercial Royal Jelly samples analysed presented variable physico-chemical characteristics that correspond with the values given by international quality standard proposals for Royal Jelly.

    Royal jelly (RJ), especially its protein components, has been shown to possess immunomodulatory activity. However, almost nothing is known about the influence of RJ fatty acids on the immune system. In this work we studied the effect of 10-hydroxy-2-decanoic acid (10-HDA) and 3,10-dihydroxy-decanoic acid (3,10-DDA), isolated from RJ, on the immune response using a model of rat dendritic cell (DC)-T-cell cocultures. Both fatty acids, at higher concentrations, inhibited the proliferation of allogeneic T cells. The effect of 10-HDA was stronger and was followed by a decrease in interleukin-2 (IL-2) production and down-regulation of IL-2 receptor expression. Spleen DC, cultivated with 10 microg/ml of fatty acids down-regulated the expression of CD86 and the production of IL-12, but up-regulated the production of IL-10. In contrast, DC, pretreated with 100 microg/ml of 3,10-DDA, up-regulated the expression of CD86 and augmented the proliferation of allogeneic T cells. The highest dose (200 microg/ml) of both fatty acids which was non-apoptotic for both T cells and DC, down-regulated the expression of MHC class II and CD86, decreased the production of IL-12 and made these DC less allostimulatory. The immunosuppressive activity of 3,10-DDA was also confirmed in vivo, using a model of Keyhole lymphet hemocyanine immunization of rats. In conclusion, our results showed the immunomodulatory activity of RJ fatty acids and suggest that DC are a significant target of their action.

    Full Text Available Na produção de mudas de fruteiras em geral, o uso de solo na composição de substratos ainda é a prática mais econômica e utilizada pelos agricultores, embora haja o risco deste conter inóculos de fitopatógenos. Visando uma alternativa à esterilização química com brometo de metila, neste trabalho avaliou-se a eficiência de coletores solares para a desinfestação de substratos contendo solo, na erradicação de escleródios de S. rolfsii, em Campos dos Goytacazes-RJ. Os ensaios foram realizados nos dias: 6 e 25 de outubro e 13 de dezembro de 2000. Os escleródios recuperados dos substratos tratados nos coletores solares foram plaqueados em meio de cultura e submetidos à coloração em solução de cloreto de trifenil-tetrazólio (TCT. A coloração em TCT foi utilizada para comprovar se os escleródios não-germinados em meio de cultura foram realmente inativados pelo calor ou se houve indução de fungistase. No primeiro ensaio, em dia nublado, o máximo de temperatura alcançado no substrato foi de 45ºC e a germinação dos escleródios foi nula e acompanhada de 100% de colonização por bactérias. Nas duas últimas datas de avaliação, em dias ensolarados, as temperaturas máximas alcançadas nos substratos variaram de 60 a 80ºC e os escleródios foram totalmente erradicados, em apenas um dia de tratamento. Nos três ensaios, os escleródios tratados não apresentaram atividade de desidrogenase, evidenciada pela falta de coloração avermelhada interna na presença de TCT, corroborando a inativação pelo calor. Conclui-se que mesmo em condições sub-ótimas para tratamento de substratos em coletores solares, a exposição prolongada a temperaturas elevadas foi suficientemente danosa aos escleródios do patógeno, tornando-os mais vulneráveis ao antagonismo microbiano. Os coletores solares foram eficientes na desinfestação dos substratos, visando o controle de S. rolfsii, nas condições avaliadas.Although there is a

The regression coefficient (r² for the models fitting was satisfactory, with better results for model M2 (r² = 0.557 compared to model M1 (r² = 0.334. The weather variables presented negative correlation with PM10, with the exception of the wind direction index, which, similarly to PM10, i-1, had positive correlation. The air relative humidity and the rainfall were the most significant weather variables in the models. However, PM10, i-1 was the most significant variable, when included in the model. The air temperature was statistically not significant (p > 0.05 for both models. M2 model showed an agreement between the estimated and observed values and a better precision than M1 model. In terms of air quality forecast, both models presented satisfactory results, but model M2 was superior.

Three thousand mg of royal jelly (RJ or a placebo in 100 ml liquid/day were ingested for 6 months. The primary outcomes were changes in anthropometric measurements and biochemical indexes from baseline to 6 months after intervention. Results Thirty subjects in the RJ group and 26 in the control group were included in the analysis of endpoints. In an adjusted mean change of the variables from the baseline, significant differences between the two groups could be found in red blood cell counts (+0.16x106 /μL for the RJ group vs. -0.01x106 /μL for the control group, P = 0.0134, hematocrit (+0.9% vs. -0.8%, P = 0.0251, log (fasting plasma glucose (+0.01 ± 0.01 log mg/dL vs. +0.05 ± 0.01 log mg/dL, P = 0.0297, log (insulinogenic index (+0.25 vs. -0.13, P = 0.0319, log dehydroepiandrosterone sulfate (DHEA-S (+0.08 log μg/dL vs. +0.20 log μg/dL, P = 0.0483, log testosterone (T (+0.12 ± 0.04 log ng/mL vs. -0.02 ± 0.05 log ng/mL, P = 0.0416, log T/DHEA-S ratio (+0.05 ± 0.05 vs. -0.23 ± 0.59, P = 0.0015, and in one of the SF-36 subscale scores, mental health (MH (+4 vs. -7, P = 0.0276. Conclusions Six-month ingestion of RJ in humans improved erythropoiesis, glucose tolerance and mental health. Acceleration of conversion from DHEA-S to T by RJ may have been observed among these favorable effects.

  12. Model-free aftershock forecasts constructed from similar sequences in the past

    The basic premise behind aftershock forecasting is that sequences in the future will be similar to those in the past. Forecast models typically use empirically tuned parametric distributions to approximate past sequences, and project those distributions into the future to make a forecast. While parametric models do a good job of describing average outcomes, they are not explicitly designed to capture the full range of variability between sequences, and can suffer from over-tuning of the parameters. In particular, parametric forecasts may produce a high rate of "surprises" - sequences that land outside the forecast range. Here we present a non-parametric forecast method that cuts out the parametric "middleman" between training data and forecast. The method is based on finding past sequences that are similar to the target sequence, and evaluating their outcomes. We quantify similarity as the Poisson probability that the observed event count in a past sequence reflects the same underlying intensity as the observed event count in the target sequence. Event counts are defined in terms of differential magnitude relative to the mainshock. The forecast is then constructed from the distribution of past sequences outcomes, weighted by their similarity. We compare the similarity forecast with the Reasenberg and Jones (RJ95) method, for a set of 2807 global aftershock sequences of M≥6 mainshocks. We implement a sequence-specific RJ95 forecast using a global average prior and Bayesian updating, but do not propagate epistemic uncertainty. The RJ95 forecast is somewhat more precise than the similarity forecast: 90% of observed sequences fall within a factor of two of the median RJ95 forecast value, whereas the fraction is 85% for the similarity forecast. However, the surprise rate is much higher for the RJ95 forecast; 10% of observed sequences fall in the upper 2.5% of the (Poissonian) forecast range. The surprise rate is less than 3% for the similarity forecast. The similarity

    Royal Jelly (RJ) is bee product, rich in proteins, vitamins, enzymes, minerals, hormones (trace elements of testosterone), lipids, glucides, niacin, pantothenic acid, biotin, inositol and folic acid, which may be beneficial in neutralizing the free oxygen radicals. The present study was carried out evaluate the radio-protective effect of Royal Jelly exposure of male Swiss albino rats to 1 Gy for 5 times day post day. Royal jelly was supplemented by gavage to rats at a dose of 150 mg/ kg body wt/ day for successive 10 days through exposure to gamma radiation 1 Gy x 5 time day post day. The dose of royal jelly is equivalent to daily human nutritional supplementation quantity. The result revealed that whole body gamma-irradiation of rats produced significant decrease in plasma total protein, albumin and globulin contents and significant increase in plasma alanine transaminase (ALT) and aspartate transaminase (AST) activity. However, plasma testosterone significantly decrease and follicle-stimulating hormone (FSH) and luteinising hormone (LH) significantly increased. Cholesterol (TC), triacyleglycerol (TAC), superoxide dismutase (SOD) and glutathione per oxidise (GSHPx) decreased whereas, malondialdehde (MDA) increased. Oral administration of the RJ exerted a noticeable amelioration of the radiation induced hormonal and biochemical changes according to the results of the present study. It could be concluded that RJ possess anti-oxidative potential that may protect the liver against ?-radiation induced acute oxidative toxicity. This protective effect might be mediated, at least in part, by the limitation of culprit free radicals and the amelioration of oxidative stress and also due to the synergistic relationship between the natural components found in RJ

A utilização da análise de imagem orientada a objeto e da mineração de dados no mapeamento geomorfológico permitiu a classificação do relevo em diversas classes e em diferentes níveis taxonômicos, de forma ágil e simplificada, ficando evidente que dois fatores influenciaram fortemente os resultados: (i a segmentação multirresolução associada à possibilidade de se manipular a contribuição de cada variável, pois permitiu a elaboração de estratégias de segmentação mais adequadas aos dados utilizados e às classes geomorfológicas mapeadas; e (ii a seleção do conjunto amostral, pois tal tarefa possui uma relação direta na capacidade do minerador de dados definir parâmetros mais eficazes para a classificação do relevo. Vale ressaltar que a classificação geomorfológica por meio da análise de imagem orientada a objeto se destaca dos métodos convencionais devido a sua capacidade de classificação em diferentes níveis e sua rede hierárquica semântica, onde cada classe pode ser dividida em subclasses, adequando-se bem ao mapeamento geomorfológico taxonômico proposto. Por fim, destaca-se que, apesar do grande avanço no mapeamento por meio da OBIA e da mineração de dados, o conhecimento do intérprete sobre o conteúdo a ser mapeado continua a ser imprescindível para os procedimentos de classificação adotados.

    When a radiological or nuclear accident that leads to the release of radioactive material to the environment occurs, it is important to implement protective and remediation measures in order to reduce human exposure to radionuclides. Therefore, it is necessary that the procedures to be chosen by the affected country authorities are the most efficient ones, which can only be defined based on previously established criteria. In Brazil, since the radiological accident in Goiania, in 1987, the development of tools to support decision-making in emergencies of this nature was started. The main objective of this work was to establish an acting basis for contaminated areas, in order to protect the individuals of public in case of any accident related to Almirante Alvaro Alberto nuclear power plant, in the municipality of Angra dos Reis (RJ), which leads to contamination to the environment and the consequent exposure of local population or from more distant regions to ionizing radiation. Initially, the high-risk areas near the location of the nuclear power plant were defined. Typical urban environments found in the main cities of these municipalities were surveyed, including homes, streets and recreation areas. The main characteristics of the study area were evaluated using images from Google Earth® and web pages of the municipalities. After the types of areas to be simulated were selected, these were quantified in terms of the number of residents, the size of the streets, and the number of trees, among others, per unit area. Considering the different housing characteristics for the selected municipalities, six main standard scenarios were developed for urban areas, including homes with different shielding, buildings and parks. The simulation of the procedures for each scenario was made with SIEM model, developed by the Institute of Radiation Protection and Dosimetry (IRD/CNEN), formed by the integration of various models including CORAL, focusing on agricultural areas

J Strength Cond Res 32(6): 1571-1582, 2018-The aim of this study was to investigate changes in vertical jump technique over the course of a training session. Twelve plyometric and ballistic exercise-trained male athletes (age = 23.4 ± 4.6 years, body mass = 78.7 ± 18.8 kg, height = 177.1 ± 9.0 cm) performed 3 sets of 10 repetitions of drop jump (DJ), rebound jump (RJ) and squat jump (SJ). Each exercise was analyzed from touchdown to peak joint flexion and peak joint flexion to take-off. Squat jump was analyzed from peak joint flexion to take-off only. Jump height, flexion and extension time and range of motion, and instantaneous angles of the ankle, knee, and hip joints were measured. Separate 1-way repeated analyses of variance compared vertical jump technique across exercise sets and repetitions. Exercise set analysis found that SJ had lower results than DJ and RJ for the angle at peak joint flexion for the hip, knee, and ankle joints and take-off angle of the hip joint. Exercise repetition analysis found that the ankle joint had variable differences for the angle at take-off, flexion, and extension time for RJ. The knee joint had variable differences for flexion time for DJ and angle at take-off and touchdown for RJ. There was no difference in jump height. Variation in measured parameters across repetitions highlights variable technique across plyometric and ballistic exercises. This did not affect jump performance, but likely maintained jump performance by overcoming constraints (e.g., level of rate coding).

    Full Text Available Leishmania RNA virus (LRV has been shown to be a symbiotic component of Leishmania parasites in South America. Nested retro-transcription polymerase chain reaction was employed to investigate LRV1 presence in leishmaniasis lesions from Brazil. In endemic areas of Rio de Janeiro (RJ, no LRV1 infection was observed even with mucosal involvement. LRV1 was only detected in Leishmania (V. guyanensis cutaneous lesions from the northern region, which were obtained from patients presenting with disease reactivation after clinical cure of their primary lesions. Our results indicated that the severity of leishmaniasis in some areas of RJ, where Leishmania (V. brazi-liensis is the primary etiological agent, was not associated with Leishmania LRV1 infection.

    We have previously reported that royal jelly (RJ) from honeybees (Apis mellifera) has weak estrogenic activity mediated by interaction with estrogen receptors that leads to changes in gene expression and cell proliferation. In this study, we isolated four compounds from RJ that exhibit estrogenic activity as evaluated by a ligand-binding assay for the estrogen receptor (ER) β. These compounds were identified as 10-hydroxy-trans-2-decenoic acid, 10-hydroxydecanoic acid, trans-2-decenoic acid and 24-methylenecholesterol. All these compounds inhibited binding of 17β-estradiol to ERβ, although more weakly than diethylstilbestrol or phytoestrogens. However, these compounds had little or no effect on the binding of 17β-estradiol to ERα. Expression assays suggested that these compounds activated ER, as evidenced by enhanced transcription of a reporter gene containing an estrogen-responsive element. Treatment of MCF-7 cells with these compounds enhanced their proliferation, but concomitant treatment with tamoxifen blocked this effect. Exposure of immature rats to these compounds by subcutaneous injection induced mild hypertrophy of the luminal epithelium of the uterus, but was not associated with an increase in uterine weight. These findings provide evidence that these compounds contribute to the estrogenic effect of RJ. PMID:18830443

  12. Ending Sexual Violence Through Transformative Justice

    Full Text Available Sexual violence is used to maintain what Dr. Riane Eisler (1990 conceptualizes as the dominator model of society. The early days of the feminist anti-violence movement focused on changing the dominator model, but, in part, this focus was co-opted by seeking criminal justice solutions, contributing to punitive responses and mass incarceration that have been ineffective in ending sexual violence. The racist history of the rape charge and its disproportionate effect on people of color, an effect that continues today. Legislators have passed draconian laws that uniquely apply to anyone convicted of a sex offense, the definition of which has been broadened to encompass harmless behavior. A separate legal regime for sex offenders that isolates them from society and marks them for life as monsters obfuscates the causes of sexual violence and contributes to the problem. The feminist anti-violence movement remains influential, though little recognized, in today’s efforts to respond to sexual violence through restorative justice and transformative justice. A number of groups have adopted the RJ/TJ model, in particular women of color. The article provides examples of successful and unsuccessful implementation of RJ/TJ and discusses impediments to wider adoption of this approach. RJ/TJ is a promising alternative to the current criminal justice response to sexual assault, one that will bring us closer to a partnership culture.

  16. Nitrogen turnover of three different agricultural soils determined by 15N triple labelling

    To meet the demand for data to improve existing N turnover models and to evaluate the effect of different soil physical properties on gross nitrogen (N) transformation rates, we investigated two arable soils and a grassland soil after addition of ammonium nitrate (NH4NO3), where either ammonium (NH4+), or nitrate (NO3-), or both pools have been labelled with 15N at 60 atom% excess (triple 15N tracing method). Besides NH4+, NO3- and nitrite (NO2-) contents with their respective 15N enrichment, nitrous oxide (N2O) and dinitrogen (N2) fluxes have been determined. Each soil was adjusted to 60 % of maximum water holding capacity and pre-incubated at 20˚ C for two weeks. After application of the differently labelled N fertilizer, the soils were further incubated at 20˚ C under aerobic conditions in a He-N2-O2 atmosphere (21 % O2, 76 He, 2% N2) to increase the sensitivity of N2 rates via the 15N gas flux method. Over a 2 week period soil N pools were quantified by 2 M KCl extraction (adjusted to pH 7 to prevent nitrite losses) (Stevens and Laughlin, 1995) and N gas fluxes were measured by gas chromatography in combination with IRMS. Here, we present the pool sizes and fluxes as well as the 15N enrichments during the study. Results are discussed in light of the soil differences that were responsible for the difference in gross N dynamics quantified by the 15N tracing model Ntrace (Müller et al., 2007).

    According to the Brazilian National Database there are about 300 Nuclear Medicine Services (NMS) in Brazil, 44 of them located in the State of Rio de Janeiro (RJ). Individual dose measurements are an important input for the evaluation of occupational exposure in order to demonstrate the effectiveness of radioprotection implementation and to keep individual doses as low as possible. In Brazil, most nuclear medicine (NM) staff is routinely monitored for external dose. The internal committed dose is estimated only in abnormal conditions. This paper makes a statistics analysis of all the RJ NMS annual external occupational doses in year 2005. A study of the evolution of monthly external individual doses higher than 4.00 mSv from 2004 to 2008 is also presented. The number of registered thorax monthly dose higher than 4.0 mSv is increasing, as its value. In this period the highest dose measured reaches 56.9 mSv, in one month, in 2008. About 50% of the annual doses are smaller than the monthly record level of 0.20 mSv. In 2005, around 100 professionals of RJ NMS received annual doses higher than 4.0 mSv, considering only external doses, but no one receives doses higher than 20.0 mSv. Extremities dosimeters are used by about 15% of the staff. In some cases, these doses are more than 10 times higher than the dose in thorax. This study shows the importance to improve radiation protection procedures in NM. (author)

  5. The genetic diversity and phenotypic characterisation of Streptococcus agalactiae isolates from Rio de Janeiro, Brazil

    2011-12-01

    Full Text Available Streptococcus agalactiae isolates are more common among pregnant women, neonates and nonpregnant adults with underlying diseases compared to other demographic groups. In this study, we evaluate the genetic and phenotypic diversity in S. agalactiae strains from Rio de Janeiro (RJ that were isolated from asymptomatic carriers. We analysed these S. agalactiae strains using pulsed-field gel electrophoresis (PFGE, serotyping and antimicrobial susceptibility testing, as well as by determining the macrolide resistance phenotype, and detecting the presence of the ermA/B, mefA/E and lnuB genes. The serotypes Ia, II, III and V were the most prevalent serotypes observed. The 60 strains analysed were susceptible to penicillin, vancomycin and levofloxacin. Resistance to clindamycin, chloramphenicol, erythromycin, rifampin and tetracycline was observed. Among the erythromycin and/or clindamycin resistant strains, the ermA, ermB and mefA/E genes were detected and the constitutive macrolides, lincosamides and streptogramin B-type resistance was the most prevalent phenotype observed. The lnuB gene was not detected in any of the strains studied. We found 56 PFGE electrophoretic profiles and only 22 of them were allocated in polymorphism patterns. This work presents data on the genetic diversity and prevalent capsular serotypes among RJ isolates. Approximately 85% of these strains came from pregnant women; therefore, these data may be helpful in developing future prophylaxis and treatment strategies for neonatal syndromes in RJ.

    Sporotrichosis is a widespread subcutaneous mycosis caused by the dimorphic fungi now known as the Sporothrix schenckii complex. This complex is comprised of at least six species, including Sporothrix albicans, Sporothrix brasiliensis, Sporothrix globosa, Sporothrix luriei, Sporothrix mexicana and S. schenckii. Cases of sporotrichosis have significantly increased in Brazil over the past decade, especially in the state of Rio de Janeiro (RJ), where an epidemic among cat owners has been observed. The zoonotic transmission from cats to humans suggests a common source of infection and indicates that animals can act as vectors. We performed a molecular characterisation of samples collected during the first outbreak of familial sporotrichosis caused by S. brasiliensis in the state of Espírito Santo, Brazil. These results represent the first description of such an outbreak outside the endemic area of zoonotic sporotrichosis in RJ.

    2017-08-01

    New photometric follow-up observations of transitting 'hot Jupiters' TrES-3b and Qatar-1b are presented. Weighted mean values of the solutions of light curves in R-filter for both planetary systems are reported and compared with the previous results. The transit light curves were analysed using the WINFITTER code. The physical properties of the planets were estimated. The planet radii are found to be Rp = 1.381 ± 0.033RJ for TrES-3b and Rp = 1.142 ± 0.025RJ for Qatar-1b. Transit times and their uncertainties were also determined and a new linear ephemeris was computed for both systems. Analysis of transit times showed that a significant signal could not be determined for TrES-3b, while weak evidence was found for Qatar-1b, which might be tested using more precise future transit times.

  17. 'Acceptable rebellion': marketing hipster aesthetics to sell Camel cigarettes in the US.

    Science.gov (United States)

    Hendlin, Yogi; Anderson, Stacey J; Glantz, Stanton A

    2010-06-01

    The aim of the present work was to understand why and how RJ Reynolds and other tobacco companies have marketed tobacco products to young adult social trendsetting consumers (termed 'hipsters') to recruit trendsetters and average consumers to smoke. Analysis of tobacco industry documents and industry marketing materials. Since 1995, RJ Reynolds developed its marketing campaigns to better suit the lifestyle, image identity and attitudes of hip trendsetters (so-called 'hipsters'), and Camel's brand identity actively shifted to more closely convey the hipster persona. Camel emphasised in-venue events such as promotional music tours to link the brand and smoking to activities and symbols appealing to hipsters and their emulating masses. To reach this targeted and socially valuable trend-setting population, public health advocates must tap into hipster psychology and expose to the targeted community the tobacco company's efforts to infiltrate the hipster community to turn hipsters into tobacco-using role models.

    2015-06-18

    The purpose of this research study was to examine the experiences of prosecutors in Athens, Greece, as they implement a restorative justice (RJ; mediation) model in cases of intimate partner violence (IPV). Greece recently enacted a new legislation related to domestic violence, part of the requirement is mediation. This study used semi-structured interviews with 15 public prosecutors at the courts of first instance and three interviews with facilitators of mediation process. The findings indicate widespread role confusion. Prosecutors' experiences, professional positions, and views of RJ in adult cases of gendered violence were shaped by their legal training. That is, their perceptions reflected their work in an adversarial system. Their views were complex yet ultimately unreceptive and their practices failed the victims of IPV. The study report concluded with recommendations for the legislators and for better preparation of court actors. © The Author(s) 2015.

    Industrial irradiation is the practice that, making use of electron beams or gamma rays, provides benefits such as sterilization of hospital products, food preservation, treatment of precious stones, the aging of cachaça and the preservation of works of art. The objective of the work is to characterize the overview of industrial irradiation services operating in the state of Rio de Janeiro (RJ). The methodology involved a survey of the installations licensed by the Brazilian National Nuclear Energy Commission (CNEN) for the industrial irradiation operation in the state. Technical visits were organized at the Radiological Protection Services of all detected facilities. It was found that there are only two installations authorized by CNEN in RJ and both use electron beam irradiation. Only one of them acts with the commercialization of the service, employing a 10-mega electron-volt double beam from two linear particle accelerators. The second facility uses the service for its own purposes, equipped with a single accelerator, single-beam 600-kilo electron-volt emitter. It is concluded that, numerically, there are few industrial irradiation facilities in RJ. Based on characteristics such as beam penetrability, the nature of the source, logistic cost and radiation protection measures, these facilities prefer to make use of accelerators (electron beams). It should be noted that if the only company that currently offers the service to third parties decides to close its activities, manufacturers, suppliers, and consequently the population can suffer some impact, given the absence of options in the market.

    We recently reported the first evidence of placental endoplasmic reticulum (ER) stress in the pathophysiology of human intrauterine growth restriction. Here, we used a mouse model to investigate potential underlying mechanisms. Eif2s1(tm1RjK) mice, in which Ser51 of eukaryotic initiation factor 2 subunit alpha (eIF2α) is mutated, display a 30% increase in basal translation. In Eif2s1(tm1RjK) placentas, we observed increased ER stress and anomalous accumulation of glycoproteins in the endocrine junctional zone (Jz), but not in the labyrinthine zone where physiological exchange occurs. Placental and fetal weights were reduced by 15% (97 mg to 82 mg, p growth factor for placental development; indeed, activity in the Pdk1-Akt-mTOR pathways was decreased in Eif2s1(tm1RjK) placentas, indicating loss of Igf2 signalling. Furthermore, we observed premature differentiation of trophoblast progenitors at E9.5 in mutant placentas, consistent with the in vitro results and with the disproportionate development of the labyrinth and Jz seen in placentas at E18.5. Similar disproportion has been reported in the Igf2-null mouse. These results demonstrate that ER stress adversely affects placental development, and that modulation of post-translational processing, and hence bioactivity, of secreted growth factors contributes to this effect. Placental dysmorphogenesis potentially affects fetal growth through reduced exchange capacity. Copyright © 2012 Pathological Society of Great Britain and Ireland.

    In 2006, RJ Reynolds began test-marketing Camel Snus, a new smokeless tobacco (SLT) product. Promotion included use of a brand website, a relatively new marketing channel used by tobacco companies, which allowed visitors to learn about the product and discuss it with others on the website's message board. Our study aimed to examine early experiences with and perceptions of Camel Snus as described by board contributors and also to consider the use and benefits of the message board for both consumers and the company. We conducted a qualitative analysis, coding each message in Atlas.Ti and analysing it for emerging themes and patterns. Messages were also coded for demographic information where evident, such as tobacco use status and geographical location. Descriptive data and illustrative quotes are presented. Board participants described being introduced to Camel Snus through free samples. Favourable evaluations were posted by current smokers who had never tried SLT before as well as current users of other SLT brands. Messages indicated both initiation of dual product use among smokers and product substitution. Participants used the board to advise each other on how to use the product, where to get more, suggest ways RJ Reynolds could improve the product and to encourage RJ Reynolds to release it nationally. Camel Snus has appeal for at least some smokers and SLT users. Camel Snus' website message board may have been a doubly beneficial marketing feature in both connecting product users and providing product feedback to the company during test-marketing.

    In recent years, intriguing hints for the violation of lepton flavor universality (LFU) have been accumulated in semileptonic B decays, both in the charged-current transitions b →c ℓ-ν¯ℓ(i.e., RD, RD*,and RJ /ψ) and the neutral-current transitions b →s ℓ+ℓ-(i.e., RK and RK*). Hints for LFU violation in RD(*) and RJ /ψ point at large deviations from the standard model (SM) in processes involving tau leptons. Moreover, LHCb has reported deviations from the SM expectations in b →s μ+μ- processes as well as in the ratios RK and RK*, which together point at new physics (NP) affecting muons with a high significance. These hints for NP suggest the possibility of huge LFU-violating effects in b →s τ+τ- transitions. In this Letter, we predict the branching ratios of B →K τ+τ-, B →K*τ+τ-, and Bs→ϕ τ+τ-, taking into account NP effects in the Wilson coefficients C9(') ττ and C10(') τ τ. Assuming a common NP explanation of RD , RD(*), and RJ /ψ, we show that a very large enhancement of b →s τ+τ- processes, of around 3 orders of magnitude compared to the SM, can be expected under fairly general assumptions. We find that the branching ratios of Bs→τ+τ-, Bs→ϕ τ+τ-, and B →K(*)τ+τ- under these assumptions are in the observable range for LHCb and Belle II.

  4. “Gone are the days of mass-media marketing plans and short term customer relationships”: tobacco industry direct mail and database marketing strategies

    Science.gov (United States)

    Lewis, M Jane; Ling, Pamela M

    2015-01-01

    Background As limitations on traditional marketing tactics and scrutiny by tobacco control have increased, the tobacco industry has benefited from direct mail marketing which transmits marketing messages directly to carefully targeted consumers utilising extensive custom consumer databases. However, research in these areas has been limited. This is the first study to examine the development, purposes and extent of direct mail and customer databases. Methods We examined direct mail and database marketing by RJ Reynolds and Philip Morris utilising internal tobacco industry documents from the Legacy Tobacco Document Library employing standard document research techniques. Results Direct mail marketing utilising industry databases began in the 1970s and grew from the need for a promotional strategy to deal with declining smoking rates, growing numbers of products and a cluttered media landscape. Both RJ Reynolds and Philip Morris started with existing commercial consumer mailing lists, but subsequently decided to build their own databases of smokers’ names, addresses, brand preferences, purchase patterns, interests and activities. By the mid-1990s both RJ Reynolds and Philip Morris databases contained at least 30 million smokers’ names each. These companies valued direct mail/database marketing’s flexibility, efficiency and unique ability to deliver specific messages to particular groups as well as direct mail’s limited visibility to tobacco control, public health and regulators. Conclusions Database marketing is an important and increasingly sophisticated tobacco marketing strategy. Additional research is needed on the prevalence of receipt and exposure to direct mail items and their influence on receivers’ perceptions and smoking behaviours. PMID:26243810

    Full Text Available OBJETIVO: Existe uma expressiva subnotificação de casos de Aids no Município do Rio de Janeiro, RJ. Nesse sentido, foi realizado estudo com o objetivo de analisar os fatores associados a esse evento. MÉTODOS: Com base em dados do Sistema de Informações Hospitalares do Sistema Único de Saúde, referentes ao ano de 1996 e ao Município do Rio de Janeiro, e do Sistema de Informações sobre Agravos de Notificação, atualizado até setembro de 1997, selecionou-se uma amostra aleatória de prontuários, pela qual os pacientes foram classificados em notificados, não notificados e sem evidência para notificação. Foi utilizado um modelo multinomial para a análise das chances de ocorrência de subnotificação versus notificação e não-notificação sem evidência de diagnóstico de Aids versus notificação. RESULTADOS: Não foram encontradas associações estatisticamente significativas entre as variáveis "idade", "estado civil", "escolaridade", "ocupação" e "gravidade da doença" e subnotificação de casos de Aids. A variável "sexo feminino" apresentou forte associação com as internações por procedimento Aids sem evidências para `fechar caso' dessa doença. Foi encontrada associação bastante expressiva entre ter sido internado no mesmo hospital mais de uma vez e estar notificado. A presença de um setor de vigilância epidemiológica no hospital esteve inversamente associada à subnotificação de casos de Aids. CONCLUSÕES: Os resultados mostraram que a associação significativa entre variáveis organizacionais e estruturais e subnotificação de casos de AIDS apontam para a necessidade de normatização de processos e fluxos, a fim de melhorar a qualidade do sistema de informações em saúde.OBJECTIVE: The underreporting of AIDS cases in the municipality of Rio de Janeiro, Brazil, is significant.

    Hendlin, Yogi; Anderson, Stacey J; Glantz, Stanton A

    2011-01-01

    Objective The aim of the present work was to understand why and how RJ Reynolds and other tobacco companies have marketed tobacco products to young adult social trendsetting consumers (termed ‘hipsters’) to recruit trendsetters and average consumers to smoke. Methods Analysis of tobacco industry documents and industry marketing materials. Results Since 1995, RJ Reynolds developed its marketing campaigns to better suit the lifestyle, image identity and attitudes of hip trendsetters (so-called ‘hipsters’), and Camel’s brand identity actively shifted to more closely convey the hipster persona. Camel emphasised in-venue events such as promotional music tours to link the brand and smoking to activities and symbols appealing to hipsters and their emulating masses. Conclusions To reach this targeted and socially valuable trend-setting population, public health advocates must tap into hipster psychology and expose to the targeted community the tobacco company’s efforts to infiltrate the hipster community to turn hipsters into tobacco-using role models.

  16. Campus Sexual Misconduct: Restorative Justice Approaches to Enhance Compliance With Title IX Guidance.

    Science.gov (United States)

    Koss, Mary P; Wilgus, Jay K; Williamsen, Kaaren M

    2014-07-01

    Campus response to sexual violence is increasingly governed by federal law and administrative guidance such as the 1972 Title IX, the 2011 Dear Colleague Letter (DCL), and the 2013 Violence Against Women Act. Educational institutions are directed to expand disciplinary responses and establish coordinated action to eliminate sexual violence and remedy its effects. Compliance fosters a quasi-criminal justice approach not suited to all sexual misconduct and inconsistent with developing practice in student conduct management. This article envisions restorative justice (RJ) enhancements to traditional student conduct processes that maintain compliance, expand options, empower victim choice, and increase responsiveness to DCL aims. The article (1) defines sexual violence and sexual harassment within the DCL scope, (2) elaborates the DCL position on permissible alternative resolutions and differentiates mediation from RJ, (3) sequences action steps from case report to finalization, including both restorative and traditional justice pathways; and (4) discusses building support for innovation beginning with existing campus response. © The Author(s) 2014.

  17. The RESTORE program of restorative justice for sex crimes: vision, process, and outcomes.

    Koss, Mary P

    2014-06-01

    The article reports empirical evaluation of RESTORE, a restorative justice (RJ) conferencing program adapted to prosecutor-referred adult misdemeanor and felony sexual assaults. RESTORE conferences included voluntary enrollment, preparation, and a face-to-face meeting where primary and secondary victims voice impacts, and responsible persons acknowledge their acts and together develop a re-dress plan that is supervised for 1 year. Process data included referral and consent rates, participant characteristics, observational ratings of conferences compared with program design, services delivered, and safety monitoring. Outcome evaluation used 22 cases to assess (a) pre-post reasons for choosing RESTORE, (b) preparation and conference experiences, (c) overall program and justice satisfaction, and (d) completion rates. This is the first peer-reviewed quantitative evaluation of RJ conferencing for adult sexual assault. Although the data have limitations, the results support cautious optimism regarding feasibility, safety, and satisfactory outcomes. They help envision how conferencing could expand and individualize justice options for sexual assault.

  19. Oral administration of royal jelly restores tear secretion capacity in rat blink-suppressed dry eye model by modulating lacrimal gland function.

    Directory of Open Access Journals (Sweden)

    Toshihiro Imada

    Full Text Available Tears are secreted from the lacrimal gland (LG, a dysfunction in which induces dry eye, resulting in ocular discomfort and visual impairment. Honey bee products are used as a nutritional source in daily life and medicine; however, little is known about their effects on dry eye. The aim of the present study was to investigate the effects of honey bee products on tear secretion capacity in dry eye. We selected raw honey, propolis, royal jelly (RJ, pollen, or larva from commercially available honey bee products. Tear secretion capacity was evaluated following the oral administration of each honey bee product in a rat blink-suppressed dry eye model. Changes in tear secretion, LG ATP content, and LG mitochondrial levels were measured. RJ restored the tear secretion capacity and decrease in LG ATP content and mitochondrial levels to the largest extent. Royal jelly can be used as a preventative intervention for dry eye by managing tear secretion capacity in the LG.

    In Brazil, there is no restriction to the use of organotins (OTs). Previous investigations have shown that hepatic ΣSn in cetaceans is predominantly organic. Hepatic ΣSn concentrations were determined by GFAAS in 67 cetaceans (13 species) that stranded on Rio de Janeiro (RJ) and Espirito Santo (ES) states. Concentrations (in ng/g wet wt.) of marine tucuxis (n = 20) from the highly contaminated Guanabara Bay (in RJ) varied from 1703 to 9638. Concentrations of three marine tucuxi foetuses and one newborn calf (all from Guanabara Bay) varied between 431 and 2107. Contrastingly, the maximum level among 19 oceanic dolphins was 346, and 15 out of these 19 specimens presented concentrations below detection limit. The levels of Sn in six marine tucuxis from a less contaminated area (ES) varied from below detection limit to 744. Comparing to the literature, coastal cetaceans from Brazil appear to be highly exposed to OTs. - Cetaceans from Brazil are highly exposed to organotin compounds

    We report the discovery of Qatar-3b, Qatar-4b, and Qatar-5b, three new transiting planets identified by the Qatar Exoplanet Survey. The three planets belong to the hot Jupiter family, with orbital periods of {P}{{Q}3{{b}}} = 2.50792 days, {P}{{Q}4{{b}}} = 1.80539 days, and {P}{{Q}5{{b}}} = 2.87923 days. Follow-up spectroscopic observations reveal the masses of the planets to be {M}{{Q}3{{b}}} = 4.31 ± 0.47 {M}{{J}}, {M}{{Q}4{{b}}} = 6.10 ± 0.54 {M}{{J}}, and {M}{{Q}5{{b}}} = 4.32 ± 0.18 {M}{{J}}, while model fits to the transit light curves yield radii of {R}{{Q}3{{b}}} = 1.096 ± 0.14 {R}{{J}}, {R}{{Q}4{{b}}} = 1.135 ± 0.11 {R}{{J}}, and {R}{{Q}5{{b}}} = 1.107 ± 0.064 {R}{{J}}. The host stars are low-mass main sequence stars with masses and radii M Q3 = 1.145 ± 0.064 M ⊙, M Q4 = 0.896 ± 0.048 M ⊙, M Q5 = 1.128 ± 0.056 M ⊙ and R Q3 = 1.272 ± 0.14 R ⊙, R Q4 = 0.849 ± 0.063 R ⊙, and R Q5 = 1.076 ± 0.051 R ⊙ for Qatar-3, 4, and 5 respectively. The V magnitudes of the three host stars are V Q3 = 12.88, V Q4 = 13.60, and V Q5 = 12.82. All three new planets can be classified as heavy hot Jupiters (M > 4 M J).

  9. Simple Analytic Collisional Rates for non-LTE Vibrational Populations in Astrophysical Environments: the Cases of Circumstellar SiO Masers and Shocked H2

    Science.gov (United States)

    Bieniek, Ronald

    2008-05-01

    Rates for collisionally induced transitions between molecular vibrational levels are important in modeling a variety of non-LTE processes in astrophysical environments. Two examples are SiO masering in circumstellar envelopes in certain late-type stars [1] and the vibrational populations of molecular hydrogen in shocked interstellar medium [cf 2]. A simple exponential-potential model of molecular collisions leads to a two-parameter analytic expression for state-to-state and thermally averaged rates for collisionally induced vibrational-translational (VT) transitions in diatomic molecules [3,4]. The thermally averaged rates predicted by this formula have been shown to be in excellent numerical agreement with absolute experimental and quantum mechanical rates over large temperature ranges and initial vibrational excitation levels in a variety of species, e.g., OH, O2, N2 [3] and even for the rate of H2(v=1)+H2, which changes by five orders of magnitude in the temperature range 50-2000 K [4]. Analogous analytic rates will be reported for vibrational transitions in SiO due to collisions with H2 and compared to the numerical fit of quantum-mechanical rates calculated by Bieniek and Green [5].

  10. Two-Rockets Thought Experiment

    2014-03-01

    Let n>=2 be identical rockets: R1 ,R2 , ..., Rn. Each of them moving at constant different velocities respectively v1, v2, ..., vn on parallel directions in the same sense. In each rocket there is a light clock, the observer on earth also has a light clock. All n + 1 light clocks are identical and synchronized. The proper time Δt' in each rocket is the same. Let's focus on two arbitrary rockets Ri and Rjfrom the previous n rockets. Let's suppose, without loss of generality, that their speeds verify virocket Rj is contracted with the factor C(vj -vi) , i.e. Lj =Lj' C(vj -vi) .(2) But in the reference frame of the astronaut in Rjit is like rocket Rjis stationary andRi moves with the speed vj -vi in opposite direction. Therefore, similarly, the non-proper time interval as measured by the astronaut inRj with respect to the event inRi is dilated with the same factor D(vj -vi) , i.e. Δtj . i = Δt' D(vj -vi) , and rocketRi is contracted with the factor C(vj -vi) , i.e. Li =Li' C(vj -vi) .But it is a contradiction to have time dilations in both rockets. (3) Varying i, j in {1, 2, ..., n} in this Thought Experiment we get again other multiple contradictions about time dilations. Similarly about length contractions, because we get for a rocket Rj, n-2 different length contraction factors: C(vj -v1) , C(vj -v2) , ..., C(vj -vj - 1) , C(vj -vj + 1) , ..., C(vj -vn) simultaneously! Which is abnormal.

  11. "Gone are the days of mass-media marketing plans and short term customer relationships": tobacco industry direct mail and database marketing strategies.

    Science.gov (United States)

    Lewis, M Jane; Ling, Pamela M

    2016-07-01

    As limitations on traditional marketing tactics and scrutiny by tobacco control have increased, the tobacco industry has benefited from direct mail marketing which transmits marketing messages directly to carefully targeted consumers utilising extensive custom consumer databases. However, research in these areas has been limited. This is the first study to examine the development, purposes and extent of direct mail and customer databases. We examined direct mail and database marketing by RJ Reynolds and Philip Morris utilising internal tobacco industry documents from the Legacy Tobacco Document Library employing standard document research techniques. Direct mail marketing utilising industry databases began in the 1970s and grew from the need for a promotional strategy to deal with declining smoking rates, growing numbers of products and a cluttered media landscape. Both RJ Reynolds and Philip Morris started with existing commercial consumer mailing lists, but subsequently decided to build their own databases of smokers' names, addresses, brand preferences, purchase patterns, interests and activities. By the mid-1990s both RJ Reynolds and Philip Morris databases contained at least 30 million smokers' names each. These companies valued direct mail/database marketing's flexibility, efficiency and unique ability to deliver specific messages to particular groups as well as direct mail's limited visibility to tobacco control, public health and regulators. Database marketing is an important and increasingly sophisticated tobacco marketing strategy. Additional research is needed on the prevalence of receipt and exposure to direct mail items and their influence on receivers' perceptions and smoking behaviours.

    We perform a comparison of soft-gluon resummation in SCET vs. direct QCD (dQCD), using Higgs boson production in gluon fusion as a case study, with the goal of tracing the quantitative impact of each source of difference between the two approaches. We show that saddle-point methods enable a direct quantitative comparison despite the fact that the scale which is resummed in the two approaches is not the same. As a byproduct, we put in one-to-one analytic correspondence various features of either approach: specifically, we show how the SCET method for treating the Landau pole can be implemented in dQCD, and how the resummation of the optimal partonic scale of dQCD can be implemented in SCET. We conclude that the main quantitative difference comes from power-suppressed subleading contributions, which could in fact be freely tuned in either approach, and not really characteristic of either. This conclusion holds for Higgs production in gluon fusion, but it is in fact generic for processes with similar kinematics. For Higgs production, everything else being equal, SCET resummation at NNLL in the Becher-Neubert implementation leads to essentially no enhancement of the NNLO cross-section, unlike dQCD in the standard implementation of Catani et al.

    We perform a comparison of soft-gluon resummation in SCET vs. direct QCD (dQCD), using Higgs boson production in gluon fusion as a case study, with the goal of tracing the quantitative impact of each source of difference between the two approaches. We show that saddle-point methods enable a direct quantitative comparison despite the fact that the scale which is resummed in the two approaches is not the same.

    The scales in planetary magnetospheres range from 10s of planetary radii to kilometers. For a number of years we have studied the magnetospheres of Jupiter and Saturn by using 3-dimensional magnetohydrodynamic (MHD) simulations. However, we have not been able to reach even the limits of the MHD approximation because of the large amount of computer resources required. Recently thanks to the progress in supercomputer systems, we have obtained the capability to simulate Jupiter's magnetosphere with 1000 times the number of grid points used in our previous simulations. This has allowed us to combine the high resolution global simulation with a micro-scale simulation of the Jovian magnetosphere. In particular we can combine a hybrid (kinetic ions and fluid electrons) simulation with the MHD simulation. In addition, the new capability enables us to run multi-parameter survey simulations of the Jupiter-solar wind system. In this study we performed a high-resolution simulation of Jovian magnetosphere to connect with the hybrid simulation, and lower resolution simulations under the various solar wind conditions to compare with Hisaki and Juno observations. In the high-resolution simulation we used a regular Cartesian gird with 0.15 RJ grid spacing and placed the inner boundary at 7 RJ. From these simulation settings, we provide the magnetic field out to around 20 RJ from Jupiter as a background field for the hybrid simulation. For the first time we have been able to resolve Kelvin Helmholtz waves on the magnetopause. We have investigated solar wind dynamic pressures between 0.01 and 0.09 nPa for a number of IMF values. These simulation data are open for the registered users to download the raw data. We have compared the results of these simulations with Hisaki auroral observations.

    The environmental pollution by human activity has been one of the most concerns in the last years, principally due to rapid urban growth in the cities and the industrialization process. The air pollution can be increased due to several different kinds of emissions: urban traffic, industrial activities, burning fuel, civil industry of construction/demolition, fires and natural phenomena. Many of these emissions move from long distances due to convections currents and finally tend to deposit mainly in the plants leaves and in the soil. Thus, the plants leaves works as a natural sampler by the emissions deposit in these ones. In this study Nerium oleander leaves were used to measure the environmental pollutions levels in different sampling urban regions in the city of Rio de Janeiro/RJ: Andarai, Benfica, Bonsucesso, Caju, Engenho de Dentro, Engenho Novo, Estacio, Grajau, Inhauma, Lins, Maracana, Maria da Graca, Meier, Praca da Bandeira, Riachuelo, Rio Comprido, Sao Cristovao, Tijuca, Vila Isabel and city Center. The control samples were collected in Campo Grande near of Parque Nacional da Pedra Branca/RJ (National Park of Pedra Branca/RJ). The leaves were collected from adult plants and after the collection the samples were cleaned and placed in the greenhouse for drying, then were mashed and pressed into tablets forms. The analyses were performed using the energy dispersion X-ray fluorescence (EDXRF), developed on the own laboratory and based in a SiPIN detector and a mini X ray tube. It was possible to detect 16 elements in the analyzed samples: K, Ca, Cr, Mn, Fe, Cu, Zn, Br, Rb, Sr, Ba and Pb. The results shows that, in the studied areas, the analysis of the Nerium oleander plant shows a low-cost option and with a substantial efficiency as an environmental pollution biomonitor. (author)
