    2005-01-01

    Full Text Available Se evaluaron el crecimiento y la influencia de factores ambientales bajo condiciones de cultivo suspendido del mejillón Perna perna L., P. viridis L. y una variante o morfotipo indefinido, que comparte sustrato y características morfológicas y de color de ambas especies. El estudio fue conducido durante 10 meses en la localidad de Turpialito, Golfo de Cariaco, Venezuela. Las tres poblaciones experimentales, sembradas con una talla inicial homogénea (45–50 mm presentaron un patrón de crecimiento similar; sin embargo, P. viridis mostró tasas de crecimiento significativamente menores a las de P. perna y del morfotipo, alcanzando al final del estudio 71.2, 77.0 y 77.8 mm de longitud dorso-ventral de la concha, respectivamente. Los análisis de correlatividad de los factores ambientales y el crecimiento no mostraron una modulación definida del crecimiento somático debido a factores ambientales; no obstante, la actividad reproductiva, especialmente cuando se inicia por primera vez, puede actuar como factor endógeno negativo. Aunque los resultados muestran similar respuesta fisiológica de los mejillones, se observó mayor similitud entre P. perna y el morfotipo y diferencias suficientes entre éstas y P. viridis, sugiriendo que las dos primeras pueden estar más relacionadas genéticamente. Sin embargo, existieron diferencias entre el morfotipo y P. perna, en cuanto a las características fenotípicas de la concha, supervivencia e índice gonadosomático, que pueden establecer diferencias genéticas definidas. La mayor producción gonádica en la variante sugiere su selección para el cultivo.

    Full Text Available Abstract This study aims to evaluate the effect of environmental variability on the growth and survival of the subtropical and tropical mussels Perna perna and Perna viridis at four different culture depths in the Gulf of Cariaco during an annual cycle. Juveniles of P. perna (39.1±1.88 mm in shell length and P. viridis (36.7±1.87 mm were sown on nylon ropes (3/4" and suspended from a raft at 1, 3, 6 and 9 m depths. Every six weeks, three replicates of each species were sampled (10 individuals per replicate at each depth. Growth parameters were determined: mass and shell length, dry mass of soft tissues as well as fouling and survival rates. Temperature, transparency, chlorophyll a, oxygen, salinity and particulate organic and inorganic matter were recorded at each culture depth for the purpose of relating growth and survival to environmental change. The results show that the growth of both species was linked to the environment, especially with regard to the influence of the food and temperature. A period of stagnant growth of P. perna was associated with the higher temperature and lower phytoplankton biomass that is characteristic of the season with prevalent water column stratification (August-November 2007. By contrast, the growth of P. viridis did not stagnate, although it was gradual and relatively lower. At the end, P. perna achieved higher growth rates than P. viridis. Possible culture strategies to improve the production of both mussel species are discussed.

    Full Text Available Se evaluó los cambios ocurridos en carbohidratos, proteínas y lípidos de la glándula digestiva, músculo y lóbulos gonadales de los mejillones Perna perna y P. viridis bajo condiciones de cultivo suspendido en el Golfo de Cariaco, Venezuela. Paralelamente, se llevaron registros de la condición reproductiva de ambas especies y de temperatura, clorofila a y seston. Los resultados muestraron que en los tejidos analizados de ambas especies, los lóbulos gonadales presentaron las mayores variaciones de los sustratos energéticos estudiados. La variación de los sustratos energéticos se explicó en ambos mejillones mediante desarrollo gonádico y la disponibilidad de alimento, particularmente clorofila a para P. perna y seston total para P. viridis. La temperatura fue un factor que afectó negativamente a P. viridis. Los contenidos de los diferentes sustratos energéticos observados en P. perna fueron más altos que en P. viridis, a lo largo de casi todo el periodo experimental, lo que indicó que esta especie mostró una mayor capacidad para explotar de manera más eficiente los recursos alimenticios presentes en las condiciones de cultivo suspendido.In the organisms, the variations of the biochemical composition of reproductive and somatic tissues in the growth permit to infer about its adaptative to environment. In the present study, we evaluate the changes observed in carbohydrates, lipids and proteins of digestive gland, muscle and gonad tissues of Perna perna and P. viridis, growing in suspended culture at Cariaco Gulf , Venezuela. The reproductive condition of both mussels and environmental factors (temperature, chlorophyll a and of the seston were determinate. The results show that, in both species, the gonadic lobes showed the highest variations in the biochemical component. The variations in the biochemical components were direct explained by the variations in the gonad development and the food availability, particularly chlorophyll a

    Full Text Available Cultivated mussels (Perna perna were studied to test for the effects of cleaning on their growth. These effects were examined by experimentally cleaning mussels and by changing mussel density. Treatment was performed twice, at two and four months after immerging the ropes. Two months after the first treatment and three months after the second treatment, mussels were harvested and measured (weight, length, width and thickness. Analysis of variance showed that none of the treatments resulted in increased growth of the mussels, nor did increased density result in decreased growth when compared with the control. It was concluded that it was not necessary to clean the shells to increase harvest.

    The marine environment is constantly affected by anthropic actions, with causes consequent degradation of the waters and marine biota by various discharges of xenobiotics. In the present study, the focus was the study of a region of the marine coast of the State of Sao Paulo (city of Santos), which is one of the most industrialized parts of Brazil and suffers also from a strong impact of domestic effluents. The mussel Perna perna, very abundant in the coast of the State of Sao Paulo, Brazil, was selected as the biomonitoring organism for the determination of inorganic elements and a passive biomonitoring was performed. The organisms were collected at two sites in Sao Paulo State coast: Cocanha beach in Caraguatatuba (mussel farm) and Santos Bay (Itaipu and Palmas). Seasonally, the Perna perna were collected between September/08 and July/09 in each study sites. After removal and sample preparation, the elements As, Co, Cr, Fe, Se and Zn were determined by instrumental neutron activation analysis (INAA) and Cd, Pb and Hg were determined by atomic absorption spectroscopy (AAS) in this organism.

    The aim of the present work was the study of ionizing radiation effects on aquatic biota regarding the location of nuclear facilities nearby coastal areas assuming the risk of leaks and nuclear accidents. Bivalve mollusks have been widely used in the monitoring of aquatic environment studies mainly for their sessile habit and pollutants bioconcentration ability. So marine mussel Perna perna (Bivalvia: Mytilidae) was used as organism test in this study. The study of radioactive toxicity was performed by cytotoxicity test exposing the organisms to 11Gy gamma radiation dose. After radiation the neutral red retention assay evaluated the lysosomal membrane integrity in the mussel hemocytes. 50% lethal dose assay (LD50) of gamma radiation on Perna perna mussels was carried out by exposure the organisms to {sup 60}Co gamma rays at doses ranging from 0 to 3000 Gy. The result of gamma radiation LD50 for these mussels was 1068 Gy and the neutral red retention time of irradiated organisms was about 47% lower than the control, non irradiated organisms. With the obtained results is expected to contribute in the study to identify the range of ionizing radiation doses which can cause toxic effects in marine invertebrates. (author)

    Full Text Available Perna perna mussel spat were suspended from ropes on a long-line cultivation, at Coqueiro´s Beach, Anchieta, South-eastern Brazil, in order to quantify the fouling community structure and its effects on growth and biomass of mussels. Half of the ropes had the fouling removed monthly, half had the foulingleft until the end of the experiment. Monthly samples of thirty mussels from each group were measured and their biomass determined. The fouling organisms were identified, quantified and their biomass evaluated on a monthly basis. After ten months, mussels on the cleaned treatment were significantly larger and heavier (ANOVA; P fouled, showing that fouling reduced mussel development. The most abundant epibiont organisms in terms of biomass were the algae Polysiphonia subtilissima (29% and Ulva rigida (10.3%, followed by the bryozoans Bugula neritina (13.6% and Perna perna spat (10.6%. Over 97 taxa and 42,646 individuals were identified, crustaceans being the most abundant group, predominantly one amphipod Cheiriphotis megacheles (12,980 ind.. Species abundance was positively correlated with algal biomass, revealing the influence of algae on vagile fauna, which provide both food and shelter. The benefits of fouling removal are discussed because the majority of species are important feeding items to fishes and yet, the costs of its fouling control added to the associated mussel spat loss make this fouling removal of questionable value.Sementes de Perna perna foram colocadas em cordas suspensas em long-line na Praia do Coqueiro, Anchieta, ES, objetivando-se determinar a estrutura da comunidade de incrustantes e seu efeito sobre o desenvolvimento dos mexilhões. Metade das cordas teve os incrustantes removidos mensalmente, na outra metade eles foram deixados até o final do experimento. Mensalmente, 30 mexilhões de cada grupo foram retirados e medidos e a biomassa aferida. Os incrustantes foram identificados, quantificados e a biomassa de cada taxon

  12. Aspects of growth, recruitment and conservation of the Brown Mussel Perna perna along the Tsitsikamma Coast

    Directory of Open Access Journals (Sweden)

    R. J. M Crawford

    1983-12-01

    Full Text Available Beds of brown mussels Perna perna are a dominant feature of the lower tidal range of rocky shores in the Tsitsikamma Coastal National Park. Mussels in this region attain a length of 30-40 mm by the end of their first year, and the majority probably exceed 50 mm at two years of age. Secondary settlement of plantigrades occurs from midspring through early winter, especially in summer and early autumn, and growth of adult forms is slowest prior to this settlement. Settlement occurs serially and powerful cohorts may be formed. At Nature's Valley density and biomass of mussels inside the park's boundary are significantly higher than in non-protected areas. Older age groups are also more abundant within the park.

    Aiming at the protection of aquatic biota becomes desirable progress in identifying and quantifying the presence of chemical contaminants to an evaluation of its bioavailability and harmful effects to the aquatic ecosystem. Diethyltoluamide (DEET) is one of the most commonly used active ingredients in insect repellents and is considered an emergent contaminant. In addition the environment in regions near nuclear facilities (mostly coastal) and in regions with higher level of background radiation, many aquatic organisms could be exposed to radiation, becoming more susceptible to other contaminants. Therefore, the purpose of this study was the investigation of the biological effects of ionizing radiation in combination with the exposure of Perna perna mussels to DEET. Previously it was determined the doses of {sup 60}Co gamma radiation (3 and 107 Gy) and the DEET concentrations (0.02 and 0.001mg L-1) which causes cytotoxicity in lysosomes of Perna perna mussels hemocytes. The effects were evaluated by the neutral red retention time assay in irradiated and non-irradiated organisms. The assays were performed in 72 hours, with readings on each 24 hours. The endpoint was the lysosome membrane disruption causing the decrease of the neutral red retention time observed . The results showed that was no statistic difference of irradiated organisms with 3 Gy and exposed to different concentrations of DEET in comparison with non-irradiated organisms, the mean neutral red retention time in assays was around 40 minutes. The organisms that were exposed to DEET after 107 Gy irradiation dose showed cell lysis and neutral red retention time less than 30 minutes, this suggests that synergistic effect can be observed depending on the irradiated dose and the DEET concentration.

    Full Text Available Investigations were carried out to evaluate the antioxidant defenses in digestive gland of mussels Perna perna held in air for 4 hours, exposed to air for 4 hours followed by submersion in water for 30 minutes, and constantly submerged for 4.5 hours. No differences were observed in CAT and GPx activities and in the levels of total GSH. Mussels exposed to air had significantly higher SOD activity, possibly related to a preparative mechanism of defense against oxidative stress during reoxygenation.Mexilhões são periodicamente submetidos a condições de hipóxia seguido de normóxia, como resultado das oscilações nos níveis de maré. Tais condições podem causar um aumento na produção de espécies reativas de oxigenio (EROs nos tecidos, devido a um aumento no fluxo de oxigênio e de equivalentes redutores. Para proteger as células contra as EROs, os organismos possuem enzimas antioxidantes tais como a superóxido dismutase (SOD, catalase (CAT e glutationa peroxidase (GPx, assim como o tripeptídeo glutationa (GSH. Neste trabalho, estas defesas antioxidantes foram avaliadas em glândulas digestivas de mexilhões Perna perna expostos ao ar por 4 horas seguido de re-submersão em água do mar por 30 minutos e constantemente submersos por 4,5 horas. Nenhuma diferença foi observada nas atividades da CAT e GPx, assim como nos níveis de GSH total. Mexilhões expostos ao ar tiveram atividade da SOD significativamente maior, possivelmente relacionado a um mecanismo de defesa preparativo contra o estresse oxidativo durante a reoxigenação.

    Twenty ropes with 400 Perna perna mussels seeds (3 cm shell size) were set-up on floating structures at Cabo Frio Island, Arraial do Cabo, approximately 100 km northeast of Rio de Janeiro city. A rope was taken out on a monthly basis, and the shell sizes of 100 seeds were measured. The haemolymph of 10 male and 10 female individuals was taken, and the same individuals were separated for {sup 210}Po/{sup 210}Pb determination. After one year of monthly sampling, no clear correlation was observed between the {sup 210}Po concentration, mussel's age and weight. A mean {sup 210}Po concentration of 155 Bq kg{sup -1} wet weight basis, was obtained, which is comparable with data reported in the literature. The radiation dose did not have any observable effect on the micronuclei frequency and DNA breaks in the mussels. This was probably due to the low dose rate, 0.02 mGy d{sup -1}, in comparison with the suggested potential dose limit of 10 mGy d{sup -1}.

  16. Effect of zinc and benzene on respiration and excretion of mussel larvae (Perna perna (Linnaeus, 1758 (Mollusca; Bivalvia

    Full Text Available The presence of pollutants in the ocean may affect different physiological parameters of animals. Oxygen consumption and ammonia excretion were evaluated in D-shaped larvae of mussels (Perna perna exposed to zinc sulphate (ZnSO4 and benzene (C6H6. When compared to the control group, both pollutants presented a significant reduction in oxygen consumption. A reduction in the ammonia excretion was also observed, both for ZnSO4 and C6H6 and also in the oxygen consumption. The results indicate that anaerobic metabolism may occur at the beginning of P. perna mussels development, as observed in veliger larvae. The O:N ratio under experimental conditions showed low values indicating that catabolism in veliger larvae was predominantly proteic.

    2006-03-01

    Full Text Available It has been demonstrated that the enzyme acetylcholinesterase (AChE is strongly inhibited by organophosphate and carbamate pesticides, and also by metals. However, recent reports indicate that some metals can activate AChE during acute exposure. In this work, we were interested in evaluating the effect of trace metal exposure (12, 24, 72 and 120 h on the AChE activity of Perna perna mussel’s digestive gland. Mussels exposed to Fe or Cu showed no changes in AChE activity during the whole period. Mussels exposed to Cd for 72 h or to Pb for 12 hours showed higher AChE activity than the control group. Based on these results, we hypothesize that under acute exposure, metals might interact with acetylcholine receptors, thereby affecting their binding efficiency and leading to a response involving an initial increase in AChE synthesis.

    The objective of the present work was to study the active biomonitoring of magnesium and manganese in the seashore of Sao Paulo, using the Perna perna mussel , which was transplanted from an uncontaminated region to probably contaminated sites. Mussel samples acquired in the control region, a mussel farm in Cocanha beach Caraguatatuba, were exposed for three months in the study sites, in Sao Sebastiao, Ilhabela, Ilha das Palmas and Ponta de Itaipu. The mussel samples were cleaned, grinded, homogenized, lyophilized and then analyzed by instrumental neutron activation analysis, (INAA).The INAA procedure consisted in the irradiation of the samples and synthetic standards of magnesium and manganese for 10 s, under a thermal neutron flux of 6,6 x 10 12 n cm -2 s -1 in the nuclear research reactor IEA-R1 of IPEN-CNEN/SP. The measurements of the gamma radioactivity of the samples and standards were done using an hyperpure semiconductor Ge detector, coupled to associated electronics. For analytical quality control of the results, the certified reference material (CRM) NIST SRM 1566b Oyster Tissue was analyzed and the results obtained indicated good agreement with the certified values. The results obtained in the mussel samples analysis indicated that the samples exposed in Ilhabela in the autumn season presented higher accumulation of magnesium (7051 ± 333 μg g -1 ) than the other sites. For manganese, the highest concentrations were obtained for the mussels exposed in Ilha das Palmas in springtime, with 28.5 ± 0.8 μg g -1 . It was concluded that it is possible to biomonitor magnesium and manganese by means of the analysis of Perna perna mussels. (author)

    Full Text Available Perna perna was collected from several sites along the coast of Rio de Janeiro and analysed for the content of copper, zinc, cadmium and chromium. In spite of the observed concentration variability in organisms pertaining to the same population, statistical evaluation allowed metal level differentiation among regions and sites as well as between males and females. Differences in metal contents did not confirm expectations based on source strength and existing data on water concentration.

  5. The effect of temperature and salinity on the physiological rates of the mussel Perna perna (Linnaeus 1758

    Charrid Resgalla Jr.

    2007-05-01

    Full Text Available The aim of this work was to study the rates of respiration, clearance, excretion and absorption efficiency at different temperature and salinity under laboratory conditions for Perna perna. Results showed variations in physiological rates and in acclimatization capacity which, taken together, enabled to understand its behavior in the environment, as well as to estimate its scope for growth. All experiments were carried out in static conditions, in ten replicas with one mussel by flasks. Perna perna was capable of achieving acclimatization for both clearance and absorption efficiency (15 to 30 ºC, but it achieved only partial acclimatization for respiration and excretion under chronic temperature conditions. The clearance and respiration rates increased twofold as the mussel was submitted to temperature shock, which signified a response to metabolism activity. Acclimatization to salinity was clearly the best developed capability (20 to 40 ‰. Net growth efficiency reduced as the temperature increased, but remained constant in the 20 to 35 ‰ salinity range.O molusco bivalve Perna perna é o Mytilidae de maior tamanho e o mais abundante na costa brasileira. Apresenta uma grande importância sócio-econômica devido ao seu uso na mitilicultura, disponibilizando para o consumo humano uma fonte protéica barata proporcionado pelos sistemas de cultivos costeiros. Entretanto, existe uma carência de estudos fisiológicos da espécie, que poderiam ser úteis na avaliação de novas áreas de cultivo, assim como no monitoramento de ambientes contaminados. Neste trabalho foram realizadas testes fisiológicos para determinar as taxas de respiração, clareamento, excreção e eficiência de absorção em laboratório, sob condições crônicas e agudas, em diferentes temperaturas e salinidades. Desta forma, foi possível determinar as oscilações e a capacidade de aclimatação da espécie que servem como base para o entendimento do organismo no

    Full Text Available Os metais traço apresentam grande toxicidade quando presentes em teores elevados nos organismos humano e animal. No ambiente aquático, alguns elementos formam compostos orgânicos que bioacumulam nos tecidos de organismos vivos. Os moluscos bivalves se destacam, pois possuem grande participação na dinâmica de contaminantes metálicos no ambiente marinho devido à capacidade de concentrá-los em níveis mais elevados que na água. Os mexilhões são moluscos bivalves que constituem bons indicadores de biodisponibilidade de metais, sendo amplamente utilizados como biomonitores em ecossistemas aquáticos. No Brasil, a espécie de mexilhão Perna perna é o mais cultivado devido à importância na alimentação de grande parte da população das regiões costeiras. Portanto, o consumo de mexilhões pode representar um risco à saúde humana quando proveniente de locais contaminados com metais traço, o que reforça a importância de se conhecer os teores desses elementos nos ambientes que fornecem alimento ao Homem. Devido à constante busca pela qualidade ambiental associada à utilização do mexilhão P. perna como biomonitor e como alimento, é importante conhecer o panorama de contaminação do território nacional a fim de auxiliar na prevenção de intoxicação por metais traço pelo consumo desse molusco por grande parte da população brasileira.Trace elements are considered toxic in high levels for human and animal organisms. In aquatic environment, some elements can form organic compounds and tend to bioaccumulate in organisms tissues. Bivalve mollusks participate on the metallic contaminants dynamics in aquatic environment due to capacity in concentrate trace elements in their soft tissues in higher levels than in water. Mussels are mollusks widely used as bioindicators of trace metal pollution in coastal areas because they can accumulate various elements as filter-feeders. In Brazil, Perna perna is one of the most commonly

    Full Text Available The aim of this study is to assess the marine environment quality in the Big Casablanca area. A number of biochemical markers were measured in the brown mussel, Perna perna, sampled from four sampling sites characterized by a different degree of contamination and human impacts. As biochemical indices; Catalase (CAT, Glutathione S-transferase (GST, Acetylcholinesterase (AChE, as well as Malondialdehyde (MDA and Metallothioneine (MT were evaluated in whole soft tissues of mussels collected from the selected sites. The biomarkers showed statistically significant differences at the polluted sites when compared to the control ones. Our data indicated that CAT and GST activity, MDA and MT concentration in whole mussel bodies, are a higher and significant (p < 0.05 in mussels collected at polluted sites when compared to specimen sampled from control ones. In contrary the response of AChE activity was significantly (p<0.05 inhibited in mussels from polluted sites when compared to control values. The multiple biomarker responses obtained for October 2010 and 2011, clearly demonstrate the potential presence of different contaminants in Site1 and Site2 reflecting the intensity of pollution in these areas.

    Full Text Available A ficotoxina ácido ocadaico (AO é produzida por um grupo de microalgas conhecidas como dinoflagelados. Os mexilhões, ao se alimentarem dessas microalgas, acumulam a toxina em sua glândula digestiva, desencadeando a Síndrome ou Envenenamento Diarreico por Moluscos (EDM no ser humano. Os sintomas se apresentam em torno de 30 minutos após o consumo do molusco contaminado, variando entre náuseas, dores abdominais, vômitos e diarreia. Quando a ingestão da toxina acontece em quantidades inferiores a 48µg g-1, os sintomas não se desenvolvem, porém seu consumo continuado favorece o surgimento de tumores no trato gastrointestinal em razão do poder carcinogênico do AO. Este estudo pretendeu detectar e quantificar a toxina diarreica AO em mexilhões Perna perna coletados entre os meses de maio e outubro de 2006. A detecção do AO nos mexilhões foi realizada por Cromatografia Líquida de Alta Eficiência com Detecção Fluorimétrica (CLAE-DF. Os resultados cromatográficos indicaram a presença da toxina AO em baixas concentrações, em todas as amostras de mexilhões obtidas de maio a outubro de 2006. Os resultados indicam a necessidade da elaboração e aplicação efetiva de um programa de controle higiênico-sanitário dos moluscos, assim como o monitoramento do ambiente aquático, objetivando, acima de tudo, a segurança da saúde pública.Okadaic acid (OA is a phycotoxin produced by a group of microalgae known as Dino-flagellates. When mussels feed themselves from this micro seaweed the toxin accumulates in their hepatopancreas, triggering the Syndrome or Diarrhetic Shellfish Poisoning (DSP in the human being. The symptoms appear around 30 minutes after the consumption of contaminated mussels and include abdominal nauseas, pains, vomits and diarrhea. When the toxin ingestion happens in amounts lower than 48µg g-1, the above described symptoms do not develop. However, the continued consumption favors the emergence of tumors in the

  15. Detailed Distribution of Lipids in Greenshell™ Mussel (Perna canaliculus

    Directory of Open Access Journals (Sweden)

    Matthew R. Miller

    2014-04-01

    Full Text Available Greenshell™ mussels (GSM–Perna canaliculus are a source of omega-3 (n-3 long-chain polyunsaturated fatty acids (LC-PUFA. Farmed GSM are considered to be a sustainable source of LC-PUFA as they require no dietary inputs, gaining all of their oil by filter-feeding microorganisms from sea water. GSM oil is a high-value product, with a value as much as 1000 times that of fish oils. GSM oil has important health benefits, for example, anti-inflammatory activity. It also contains several minor lipid components that are not present in most fish oil products, and that have their own beneficial effects on human health. We have shown the lipid content of the female GSM (1.9 g/100 g ww was significantly greater than that of the male (1.4 g/100 g ww. Compared with male GSM, female GSM contained more n-3 LC-PUFA, and stored a greater proportion of total lipid in the gonad and mantle. The higher lipid content in the female than the male GSM is most likely related to gamete production. This information will be useful to optimize extraction of oils from GSM, a local and sustainable source of n-3 LC-PUFA.

The control group was acclimatized in sea water 30‰. At the end of this period time, physiological measurements were carried out along with statistic analysis for filtration rates, lead assimilation and overall respiratory activity. The mechanism of multixenobiotic resistance (MXR was particularly evaluated in standardized gill fragments using rhodamine B accumulation and its quantification under fluorescence optical microscopy. Regarding the control group, results had shown that the mussels maintenance in a lead-poisoned environment caused higher filtration rates (1.04 and 2.3 and L.h-1.g-1; p < 0.05 and lower assimilation rates (71.96% and 54.1%, respectively. Also it was confirmed a lesser rhodamine B accumulation in the assays under influence of lead, suggesting that this metal induces the MXR mechanism expression in mussel P. perna. These results indicate that such physiological and biochemical alterations in the mussels can modify the energy fluxes of its metabolism, resulting in possible problems on the coastal systems used as cultivating sites.

    Vanadium determination present in seawater is of great importance to evaluate marine contamination from industrial sources as well as to identify health hazards since mussels and other marine organisms are used as food. Besides, this evaluation in the Santos coast, SP, Brazil, is important, since this area is impacted by industrial and urban activities and discharges from ships and boats. In a previous study, V results obtained for transplanted mussel (active biomonitoring) were presented. This study aimed the V determination by passive biomonitoring by analyzing Perna perna mussels collected in natural environment, from three sites in Sao Paulo State coast: Cocanha Beach (reference site), Ponta de Itaipu and Palmas Island. Ninety individuals of mussels were collected in each site between September/08 and July/09 during the four seasons of the year. After shell removal and sample preparation, V was determined by instrumental neutron activation analysis. For analytical quality control, the NIST Standard Reference Material SRM 1566b Oyster Tissue was analyzed and the results presented good accuracy. The V concentrations in mussels on dry mass basis varied from 0.77 ± 0.02 to 3.56 ± 0.88 mg kg -1 . Statistical tests were applied to the results showing differences on V concentrations among the sampling sites and season of sample collection. (author)

The research of Hg2+ bioaccumulation ability by bloodcockle (Anadara granosa and green mussel (Perna viridis using the radiotracer 203Hg2+ was conducted based on laboratory experiments design. Biokinetic parameters, such as the uptake and depuration rate and Concentration Factor, were determined to obtain predictions of Bioconcentration Factor (BCF and steady state conditions. The results of experiment using non-linear model showed that blood cockle and green mussel have the capability to accumulate Hg2+ by 15429.38 and 6963.68 times higher than its concentration in seawater after 51 days. Based on the BCF value obtained from the experiments, the predicted concentration of mercury in Anadara granosa and Perna viridis from Jakarta Bay was 1.327 and 0.599 mg.Kg-1 respectively. The predicted concentration of Hg2+ in Anadara granosa exceeds those required by ISO 7387:2009. On the other hand, the predicted in Perna viridis still meet the requirements of ISO 7387 2009.

    The coastal environment has been heavily altered by multiple environmental impacts of human activities, such as disposal of sewage from urban areas, the release of numerous chemical industries, agriculture and the flow of vessels, which can lead to accidental spills of oil and oil products, fuels and other products transported by sea. In this context, a means of determining concentrations of these potentially toxic substances in the sea water is the biomonitoring by means of different types of bivalves, which have been used by various researchers, in Brazil and other countries. With regard to bivalve mollusks, particularly mussels, their use in monitoring the marine contamination is mainly due to their wide geographic distribution, sessile habit and ability to concentrate toxic metals to 102-105 times in relation to the concentrations detected in water. In the present study, we employed the passive biomonitoring using the Perna perna bivalve mollusk with respect to the elements Br, Cl, K, Mg, Mn and V. These elements were chosen since they can be determined by INAA method (Instrumental Neutron Activation Analysis), by means of short irradiation which provides faster analyzes and also due to their importance from the standpoint of environmental or nutritional studies. The aim of this study was to evaluate the content of Br, Cl, K, Mg, Mn and V in samples of Perna perna mussels (Linnaeus, 1758: Mollusca, Bivalvia) collected in coastal regions of Sao Paulo subject to anthropogenic contamination (Ponta de Itaipu and Palmas Island, in Santos), comparing the values obtained in sites potentially impacted with the values of the control site in Praia da Cocanha, in Caraguatatuba. The collection points located in Sao Paulo coast are located in the geographical areas 23 Masculine-Ordinal-Indicator 37'S - 45 Degree-Sign 24' W (Caraguatatuba) and 23 Masculine-Ordinal-Indicator 57'S - 46 Masculine-Ordinal-Indicator 20' W (Santos).

    Recent studies have identified the presence of several emerging pollutants in aquatic environments. The occurrence in different environmental matrices has been continuously reported, highlighting the need for toxicity studies. The DEET (N,N-diethyl-meta-toluamide) is the active ingredient used in most insect repellents, and is present in many commercially available formulations. Apart from chemical pollutants, aquatic organisms are subject to exposure of ionizing radiation from natural sources or in the vicinity of nuclear power plants. The present study evaluated the toxicity of DEET in organisms irradiated and non-irradiated with 60 Co gamma radiation, and the effects that radiation causes in lysosomes of hemocytes of Perna perna mussel. For this purpose, assays were performed to identify the acute toxicity of DEET concentration and the dose of gamma radiation able to cause mortality. Subsequently, cytotoxicity assays were carried out to assess the stability of the lysosomal membrane in organisms exposed to ionizing radiation and DEET. According to the results obtained in acute toxicity tests, the concentration of DEET that causes mortality of 50% exposed organisms (LC50) is 114,27 mg L -1 , and the radiation dose that causes mortality (LD50) is 1068 Gy. In the cytotoxicity assays, the concentration of the non-observed effect (NOEC) for irradiated and non-irradiated organisms 0.0001 mg L-1 and observed effect concentration (LOEC) at concentrations above this. The IC25 (72h) for non-irradiated organisms was 0.0003 mg L-1 and IC50 (72h) was 0.0008 mg L -1 for irradiated and non-irradiated organisms. Despite of the concentrations of effect found in this study were higher than in the environment, both measurements are in the same order of magnitude and should be also take into account the possible synergistic effects of DEET with other contaminants in the aquatic environment.

    The objective of the present study was to evaluate magnesium and manganese concentrations in Perna perna mussels by applying instrumental neutron activation analysis (INAA). The mussels were collected seasonally from September 2008 to July 2009 at Cocanha Beach in the city of Caraguatatuba (clean region), and at two sites in Santos Bay (Ponta de Itaipu and Palmas Island). The mussel samples were cleaned, grinded, homogenized, lyophilized and then analyzed by INAA. The INAA procedure consisted in the irradiation of the samples and synthetic elemental standards for 10 s, under a thermal neutron flux of 6.6 x 10{sup 12} n cm{sup -2} s{sup -1} in the nuclear research reactor of IPEN-CNEN/SP. The measurements of the gamma radioactivity of the samples and standards were carried out using a hyperpure semiconductor Ge detector, coupled to Digital Spectral Analyzer. The elemental concentrations were calculated by the comparative method. For quality control of analytical results, certified reference materials NIST SRM 1566b oyster tissue and NRC DORM-2 Dogfish Muscle were analyzed and their results indicated good accuracy. The element concentrations in mussels on dry mass basis varied from 2734 {+-} 205 to 5138 {+-} 507 mg kg{sup -1} for Mg and from 7.35{+-}0.57 to 29.06{+-}3.35 mg kg{sup -1} for Mn. The results obtained in mussel analysis indicated that the samples collected in Itaipu in the winter season presented higher accumulation of Mg than the other sites. For Mn, the highest concentrations were obtained for the mussels collected in Palmas in summer time. (author)

    Variations are shown for the δ 1 3C values of green-lipped mussels, Perna canaliculus, collected on several occasions between October 1983 and April 1985 from six sites in the Marlborough Sounds, South Island, New Zealand. Additional limited data is presented for mussels from two other sites and on other fish and particulate matter. The δ 1 3C in Perna canaliculus was found to vary seasonally, with the least negative values in winter 1984. The δ 1 3C values ranged from -16.7 to -21.3 per thousand, with males on average 0.7 per thousand less negative than females. Phytoplankton composition would be expected to also vary in δ 1 3C with least negative values when at their greatest production rate, i.e. in spring or summer, and thus mussel compositions appear to show a lag of several months. There was no evidence that terrestrial food was important. (author). 25 refs.; 10 figs.; 8 tabs

    In the current study, we compared protein profiles in gills of Perna viridis after exposure to Prorocentrumlima, a dinoflagellate producing DSP toxins, and identified the differential abundances of protein spots using 2D-electrophoresis. After exposure to P. lima, the level of okadaic acid (a main component of DSP toxins) in gills of P. viridis significantly increased at 6 h, but mussels were all apparently healthy without death. Among the 28 identified protein spots by MALDI TOF/TOF-MS, 12 proteins were up-regulated and 16 were down-regulated in the P. lima-exposed mussels. These identified proteins were involved in various biological activities, such as metabolism, cytoskeleton, signal transduction, response to oxidative stress and detoxification. Taken together, our results indicated that the presence of P. lima caused DSP toxins accumulation in mussel gill, and might consequently induce cytoskeletonal disorganization,oxidative stress, a dysfunction in metabolism and ubiquitination/proteasome activity.

Los organismos expuestos a Cd mostraron una menor tolerancia al tratamiento anóxico, sin embargo una vez recuperados en el mar presentaron valores de sobrevivencia relativamente mayores en comparación a sus controles. Los organismos expuestos a Cd revelaron un incremento en la concentración de MT y la actividad de CAT, correlacionado al ingreso corporal de Cd. Los organismos transplantados al mar mostraron una disminución del metal acumulado, manteniendo niveles de MT incrementados. Los mejillones tratados y controles no exhibieron diferencias significativas en los marcadores de estrés oxidativo determinados (TBARS, GSH, GR y GST. El Cd acumulado posiblemente afectó algunas estrategias bioquímicas relacionadas con la tolerancia a la anoxia de P. viridis. Sin embargo, los altos niveles de MT en organismos pre-expuestos y posteriormente recuperados, podría condicionar la protección contra la toxicidad del Cd e indirectamente una mayor tolerancia a la anoxia.

    Wang, Wen-Xiong; Zhang, Qiong

    2013-01-01

    In this study, the aqueous uptake and dietary assimilation (trophic transfer) of two endocrine disrupting compounds (dioxin and phathalic acid) in the green mussel Perna viridis were quantified. During short-term exposure period, dioxin rapidly sorbed onto phytoplankton and its accumulation was much higher than that of phthalate. The uptake of these two compounds by the mussels increased with increasing temperature and salinity (for dioxin only). The dietary assimilation of the two contaminants was rather modest (10–64% for dioxin and 20–47% for phthalate), and was greatly dependent on the food species and concentration. Interestingly, dietary assimilation increased with increasing diatom food concentration. Gut passage time was partially responsible for the variable dietary assimilation. Given the high dissolved uptake rate and the modest dietary assimilation, aqueous exposure was predicted to be the dominant bioaccumulation source for both dioxin and phthalate in the green mussels under most conditions. -- Capsule: Aqueous uptake was the predominant pathway for dioxin and phthalate accumulation in marine green mussels

    This study describes the parasites and pathological condition of infected organ of the green mussel Perna viridis from Merambong Shoal, Western Johor Straits, Malaysia. Samples were collected randomly in November and December 2013. Histopathology techniques using Masson's Trichrome staining protocol were performed and the thin sections were observed under light microscope. Result showed that gonad was the most infected organ followed by the digestive tubule, adductor muscle, intestine and mantle tissue. The parasites (apicomplexa) such as spore-like Nematopsis, macrogamont-like coccidian, mature oocyst-like coccidian, unidentified coccidian and protozoan were found in the adductor muscle, gonad and mantle. Meanwhile, the pathological conditions were found in all infected organs except the gill, such as particular melanin deposits in cytoplasm, Rickettsia-like or Chlamydiae organism and bacteria-like inclusions. Haemocytic infiltrations were found in the surrounding connective tissues of all infected organs. However, these light infections are not causing morbidity and mortalityof the green mussel P.viridis. This study provides baseline information on health profile of the green mussel P.viridis. Further investigations are needed particularly on parasite species identification and their ecology. Understanding of the morphology and pathology of parasites infecting mollusks are very important for management of the resources.

    Perna viridis (P. viridis) has been identified as a good biological indicator in identifying environmental pollution, especially when there are various types of Heavy Metals Accumulations (HMA) inside its tissue. Based on the potential of P. viridis to accumulate heavy metals and the data on its physical properties, this study proffers to determine the relationships between both properties. The similarities of the physical properties are used to mathematical model their relationships, which included the size (length, width, height) and weight (wet and dry) of P. viridis, whilst the heavy metals are focused on concentrations of Pb, Cu, Cr, Cd and Zn. The concentrations of metal elements are detected by using Flame Atomic Adsorption Spectrometry. Results show that the mean concentration of Pb, Cu, Cr, Cd, Zn, length, width, height, wet weight and dry weight are: 1.12 +/- 1.00, 2.36 +/- 1.65, 2.12 +/- 2.74, 0.44 +/- 0.41 and 16.52 +/- 10.64 mg kg(-1) (dry weight), 105.08 +/- 14.35, 41.64 +/- 4.64, 28.75 +/- 3.92 mm, 14.56 +/- 3.30 and 2.37 +/- 0.86 g, respectively. It is also found out that the relationships between the Heavy Metals Concentrations (HMA) and the physical properties can be represented using Multiple Linear Regressions (MLR) models, relating that the HMA of Zinc has affected significantly the physical growth properties of P. viridis.

    The existence of Harmful Algae Blooms (HABs) can adversely affect the water like a mass death of fish and oxygen depletion. Some types of HABs can be contaminated with seafood and contain biotoxins that are detrimental to the health of humans who consume them. Green mussels (Perna viridis) has the properties of filter feeders so vulnerable to contamination HABs. This research was conducted to produce spatially thematic maps contaminated HABs in P. viridis so providing information about risk prediction P. viridis when consumed by humans. Sampling was done purposively in three (3) stations that represent the Bay Semarang namely western boundary waters (Kendal), middle (Semarang) and the eastern boundary (Demak). Sampling done two (2) times, namely East season (June -July) and the second transitional season (September) 2016. Analysis of HABs done either in water or body tissues of P. viridis through the analysis of food habit. The results shows that P. viridis genus positive contaminated HABs phytoplankton Tricodesmium and Ceratium. Spatial distribution and abundance of Tricodesmium genus Fitoplankton is wider and taller than the HABs Phytoplankton genus Ceratium. Group HABs are found in the tissues of P. viridis no potential as biotoxin that does not cause adverse health risks.

    With increasing recognition that maximum oxygen demand is the unifying limit in tolerance, the first line of thermal sensitivity is, as a corollary, due to capacity limitations at a high level of organisational complexity before individual, molecular or membrane functions become disturbed. In this study the tropical mussel Perna viridis were subjected to temperature change of 0.4 °C per hour from ambient to 8-36 °C. By comparing thermal mortality against biochemical indices (hsp70, gluthathione), physiological indices (glycogen, FRAP, NRRT) and behavioural indices (clearance rate), a hierarchy of thermal tolerance was therein elucidated, ranging from systemic to cellular to molecular levels. Generally, while biochemical indices indicated a stress signal much earlier than the more integrated behavioural indices, failure of the latter (indicating a tolerance limit and transition to pejus state) occurred much earlier than the other indices tending towards thermal extremities at both ends of the thermal spectrum.

    The coastal environment has been heavily altered by multiple environmental impacts of human activities, such as disposal of sewage from urban areas, the release of numerous chemical industries, agriculture and the flow of vessels, which can lead to accidental spills of oil and oil products, fuels and other products transported by sea. In this context, a means of determining concentrations of these potentially toxic substances in the sea water is the biomonitoring by means of different types of bivalves, which have been used by various researchers, in Brazil and other countries. With regard to bivalve mollusks, particularly mussels, their use in monitoring the marine contamination is mainly due to their wide geographic distribution, sessile habit and ability to concentrate toxic metals to 102-105 times in relation to the concentrations detected in water. In the present study, we employed the passive biomonitoring using the Perna perna bivalve mollusk with respect to the elements Br, Cl, K, Mg, Mn and V. These elements were chosen since they can be determined by INAA method (Instrumental Neutron Activation Analysis), by means of short irradiation which provides faster analyzes and also due to their importance from the standpoint of environmental or nutritional studies. The aim of this study was to evaluate the content of Br, Cl, K, Mg, Mn and V in samples of Perna perna mussels (Linnaeus, 1758: Mollusca, Bivalvia) collected in coastal regions of São Paulo subject to anthropogenic contamination (Ponta de Itaipu and Palmas Island, in Santos), comparing the values obtained in sites potentially impacted with the values of the control site in Praia da Cocanha, in Caraguatatuba. The collection points located in São Paulo coast are located in the geographical areas 23º 37'S - 45° 24' W (Caraguatatuba) and 23º 57'S - 46º 20' W (Santos). The collection of organisms was performed in all seasons of the year, beginning in spring 2008 and ending in winter 2009. The samples

    The phosphate occurrences of Northeastern Para and Northwestern Maranhao were formed by strong lateritic weathering of phosphorus-rich Precambrian rocks. The rock formation affected by those processes were phyllites and schists of the Gurupi Group in Cansa Perna and Pirocaua, a complex of felsic to mafic and ultramafic rocks metamorphosed in the greenschist facies in Itacupim and Trauira and probably phosphoritic sandstone in Jandia. The geology, the mineralogy of phosphates, oxides, hydroxides and silicates, the geochemistry of element distribution (aluminium, silicon, iron, calcium, etc) and trace elements distribution (strontium, rubidium, barium, rare earths, zirconium, niobium uranium, thorium, etc) and the phosphates origin are studied.

    Heavy metal concentrations and condition indices of green-fipped mussel Perna viridis were detemiined at two different sites of Peninsular Malaysia. Significant negative correlations (p< 0.001) between condition indices and heavy metals were observed. Samples from Kuala Perlis which relatively showed high heavy metals concentrations in mussels exhibited lower condition index while Kg. Tg. Batu with lower heavy metal levels, showed higher condition index. The environmental stress is believed to be responsible for the different physiological index in green-fipped mussel P. viridis.

    Full Text Available Monthly variations in the chemical composition of the mussel (Perna perna cultivated and the environment factors were studied in the Guamache Bay (Margarita Island, Venezuela. The study was carried out on mussels of 65-70 mm shell lenght and on a size that was monthly increased in 5 mm from 40-45 mm to 100-105 mm. The weight of meat ranged from 8,05 to 10,87 g, the weight of shell from 8,88 to 11,00 g and weight of the intervalve water from 2,64 to 6,83 g. In both experiences the water fluctuated between 72,2 and 86,7% ashes from 2,25 to 3,58% and proteins between 9,10 and 16,05% . The influence of the meteorological conditions on temperature and salinity was analized. The percentage of oxygen saturation was always over 80%. The primary nutrients registered low values only the ammonia mean, reached 2,43 µg-at/L Chlorophyll "a" fluctuated between 0,25 and 4,50 µg/L. The results showed that the variations in the chemical composition of mussels was independent of the size and they would be caused by the environment conditions.

    The study assesses the effects of carbon dioxide capture and storage (CCS) leaks and ocean acidification (OA) on the metal bioavailability and reproduction of the mytilid Perna perna. In laboratory-scale experiments, CCS leakage scenarios (pH 7.0, 6.5, 6.0) and one OA (pH 7.6) scenario were tested using metal-contaminated sediment elutriates and seawater from Santos Bay. The OA treatment did not have an effect on fertilisation, while significant effects were observed in larval-development bioassays where only 16 to 27 % of larva developed normally. In treatments that simulated CO 2 leaks, when compared with control, fertilisation success gradually decreased and no larva developed to the D-shaped stage. A fall in pH increased the bioavailability of metals to marine mussels. Larva shell size was significantly affected by both elutriates when compared with seawater; moreover, a significant difference occurred at pH 6.5 between elutriates in the fertilisation bioassay.

    Highlights: •Cadmium (Cd) significantly altered the proportional composition of haemocytes. •Subchronic exposure increased nuclear aberrations in gill cells. •Branchial nuclear aberrations correlated significantly with gill Cd accumulation. •Cd induced DNA damage in haemocytes. -- Abstract: Mussels are sentinel species that can be used to monitor coastal metal pollution through the application of biomarkers. Among the several important metal toxicants in coastal settings, cadmium (Cd) is of particular concern, being a non-essential metal that is known to cause harmful impacts in aquatic organisms at low concentrations. The aim of the present study was to examine the immunocytotoxic and cytogenotoxic effects of Cd on the green-lipped mussel, Perna canaliculus, under laboratory conditions. The acute (96 h; 0, 2000 and 4000 μg Cd L{sup −1}) and subchronic (28 d; 0, 200 and 2000 μg Cd L{sup −1}) toxic effects of waterborne Cd were measured in haemocytes and gill cells using differential haemocyte cell count, the micronucleus test and the comet assay. During subchronic exposure to Cd the relative counts of eosinophils and hyalinocytes increased significantly in Cd-exposed mussels while the proportion of basophils decreased. All of these effects were time- and concentration-dependent. Conversely, the relative numbers of basophils and eosinophils increased significantly during acute Cd exposure. Nuclear aberrations such as the formation of micronuclei, nuclear buds, fragmented-apoptotic cells and binuclei were observed in gill cells of Cd-exposed mussels. All of these parameters increased significantly at 2000 μg Cd L{sup −1} during subchronic exposure to Cd, and all showed a strong and significant correlation to gill Cd accumulation. Comet assay results demonstrated a significant increase in DNA damage in the haemocytes of mussels exposed to subchronic Cd concentrations. The results indicate that Cd has the capacity to induce immune system and genotoxic

    Perna viridis was used as biomonitor to assess heavy metal levels in the Chacopata-Bocaripo lagoon axis, Venezuela, during rain and drought seasons. The mussels were weighed and measured. The metal concentrations were determined by atomic absorption spectrophotometry. For rain period, the order of bioavailability was: Cu>Ni>Mn>Co>Cd>Pb, and for drought: Cu>Mn>Ni>Co>Pb>Cd. The concentrations of Ni, Co, Cd and Pb showed significant differences (P<0.05) in both periods. There was higher metal accumulation during drought season, possibly related to upwelling, since it produces an increase in primary productivity, which translates more food into organisms, making metals bioavailable for mussels. Only Cu and Mn showed significant relationships between the size and metal concentration, during drought period, it may be because of the organisms need for these essential metals in different physiological processes.

    Effect of body size on accumulation and distribution of 125 I in the green mussel (Perna Viridis), has been studied. The results showed that concentration capacity of every part in smaller mussels was higher than that in larger ones. Concentration factors of 125 I in byssus (about 0.5 x 10 3 ∼1.5 x 10 3 ), the highest in all parts of the mussels, were 30∼200 times as that in soft tissues, 200∼600 times as that in feet, 600∼1000 times as that in shells. Although wet weight of byssus was no more than 1% of whole body's wet weight, the content of 125 I accumulated in it accounted for as high as 75% of total 125 I content. The relationship between concentration factor of 125 I in byssus and whole body's wet weight (or shell length) can be described as a negative power function. (16 refs., 2 figs., 3 tabs.)

    Full Text Available Microplastics (> 5 mm have gained popularity in research and the public eye in recent years. This is due to the fact that they contain persistent organic pollutants (POPs which pose potential risks to the environment and human health. Bivalves, which are filter feeders, are considered to be good indicators of marine pollution. In this preliminary study, Asian green mussel (Perna viridis, an example of edible bivalve, cultured in Bacoor Bay, Cavite, Philippines was subjected to qualitative analysis to determine the presence of microplastics. Through microscopic analysis, microplastics were found present in the acid-digested mussel soft tissue. A management program is suggested for policy makers and stakeholders to reduce the negative impact of microplastic pollution to both humans and the marine environment.

    Full Text Available Pea crabs are globally ubiquitous symbionts in the marine environment that cause serious economic impact in the aquaculture production of several major bivalve species. However, little is known about their host-parasite interactions, especially the mating behaviour of these parasites that could prove useful for controlling their infestation in aquaculture. In this study, the mate location behaviour of male New Zealand pea crabs, Nepinnotheres novaezelandiae (Filhol, 1885, was observed when dwelling in its preferred host, the commercially important green-lipped mussel, Perna canaliculus. Given the cryptic behaviour of the male crabs, a novel trapping system was developed to determine whether male crabs would exit their mussel hosts in response to an upstream female crab. The presence of receptive female crabs placed upstream successfully attracted 60% of male crabs from their host over 24 h. Observations of the nocturnal mate-finding behaviour of male crabs were made in darkness using infrared video recordings. Males spent on average 49 min on empty hosts and never left a mussel containing a female conspecific once found, spending 200 min on average to gain entry to the mussel. Male crabs were often observed stroking the mantle edge of the mussel whilst attempting to gain entry, successfully increasing mussel valve gape during entry from 3.7 to 5.5 mm. A pheromone-based mate location system is likely used by this crab to greatly reduce the risks associated with the location of females.

    Full Text Available This study focuses on the relationship of genetics and Cs-137 radiation doses in Asian green mussel (Perna viridis collected from Chonburi province, Thailand. They might accumulate the radiocaesium from the nuclear power plants in the Asia-Pacific region including the Fukushima-Daiichi nuclear power plant via their routine or accidental releases. The radiation doses, estimated using ERICA Tool in the bivalves categorized into 3 different size classes including 4-6, 6-8, and 8-10 cm, were below 0.02 nGy/h. In parallel, Micronucleus test and Comet assay were used to investigate genetic responses in the mussels. They revealed minimum micronucleus frequency (MNF and %Tail DNA varying from 1.80-2.90% and 1.36-1.70%, respectively. The result indicates that neither particular accumulation of Cs-137 nor genetic responses among different size classes of the animals were observed. Furthermore, the radiation doses in the mussels were below the dose limit of 10 µGy/h. Therefore, no radiation effect caused by Cs-137 was found and it was also confirmed by minimal genetic damages. Data obtained can be used as site-specific data for radiological dose and impact assessment and as baseline data to establish the national radiation safety levels to protect Thai marine biota from any possible future nuclear accidents.

    Full Text Available Assessment of mercury contamination was conducted using transplanted green mussels (Perna viridis. Mussels were first exposed to HgCl2 at 0.5, 1.0, 2.5, and 5.0 nmol/L for 8 weeks at laboratory conditions. The result showed that Hg level in the water decreased rapidly, while Hg in mussels increased coincidentally with the applied doses. After 8 weeks the Hg, levels in tissue were a thousand-fold higher than that in the water. Mussels were then transplanted to 3 petroleum production platforms for field study. The result revealed that survival and growth rates of transplanted mussels at all 3 stations were in close to each other but significantly lower than that from the reference site. Hg concentrations in the tissues of transplanted mussels ranged from less than 0.010 to 0.173 µg/g, and Hg concentrations in mussel tissues from all stations were significantly increased within 2 months, while Hg levels in mussel tissues from reference site were not changed. Hg levels of transplanted mussels increased with increasing depths of the water. The transplanted mussels showed no signs of any physical anomalies, indicating that transplanted mussels could be maintained for up to 3 months in an un-natural habitat, such as petroleum production platforms, where food is much less abundant.

    2014-02-01

    Full Text Available The metallothioneins (Mts have been used as biomarkers because toxic metals such as Hg, Cd, Cu can induce their synthesis; however, environmental factors and the presence of other xenobiotics can determine the magnitude of the response in future exposures to metal ions. Metallothionein concentration was determinate in the soft tissue of Perna viridis juveniles pre-exposed to Cu and exposed to Cd (Cu/Cd for 21 days. For this, three experimental groups were established: exposed to Cd, pre-exposed to Cu and exposed to Cd and the control group (no metal. Cadmium accumulation in tissues of P. viridis was significantly higher in pre-exposed organisms to Cu, with an average value of 6.6 ± 1.9 mg/g, while in those exposed to Cd, was 4.7 ± 2.4 mg/g. Mts concentrations were also higher in the Cu/Cd experimental group, with a value of 1.36 ± 0.52 mg/g in relation to those exposed to Cd which had a value of 0.79 ± 0.47 mg/g. The relationship between Mts and bioaccumulation of Cd was significant in the group exposed to Cd, but not in the exposed Cu/Cd. These results suggest that Cu possibly acted as an inducer of Mts in the body, which led to increased accumulation of Cd in P. viridis and increase in Mts concentration. Tolerance and bioaccumulation of Cd in P. viridis was determined by previous exposure of the organism and hence its response on levels of MTs also depends on it.

É um animal de hábitos terrestres, entretanto, apresenta alguma habilidade para escalar árvores e cupinzeiros altos. As estruturas esqueléticas duras são de importância vital, pois unem e protegem os órgãos moles e ajudam a sustentar o corpo, conferem forma e envolvem-se no movimento. O esqueleto apendicular é parte importante do aparelho locomotor, cujas informações anatômicas em espécies selvagens são escassas, tornando difícil a interpretação de dados relativos a esses ossos. Este artigo teve por objetivo descrever o esqueleto do cíngulo pélvico, coxa e perna do tamanduá bandeira. Foram utilizados dois espécimes de Myrmecophaga tridactyla Linnaeus (1758, fixados em solução aquosa de formaldeído a 3,7%. Inicialmente, os membros foram desarticulados e foi realizada a retirada da pele, vísceras e musculatura associada aos ossos do cíngulo pélvico, coxa e perna dos espécimes. Em seguida, eles foram macerados em água fervente e, posteriormente, colocados em solução de peróxido de hidrogênio. Depois de limpos e secos, os ossos foram identificados e descritos. O esqueleto do cíngulo pélvico do tamanduá bandeira é constituído pelo osso do quadril, formado pelos ossos ílio, púbis e ísquio; a coxa é constituída pelo osso fêmur; e a perna pelos ossos tíbia e fíbula. Na região da articulação do joelho encontra-se a patela, um osso sesamóide relativamente pequeno, considerando-se o grande porte desse animal. O tamanduá bandeira possui características osteológicas do cíngulo pélvico, da coxa e da perna semelhantes àquelas dos carnívoros domésticos, entretanto, algumas diferenças morfológicas são evidenciadas, o que pode refletir as diferenças dos padrões locomotores.

    Highlights: •Biochemical biomarkers were measured to assess effects of Cd on Perna canaliculus. •Biochemical responses varied between acute and subchronic exposure to Cd. •MTLP induction correlated strongly with Cd accumulation. •Alkaline phosphatase and glycogen levels decreased during subchronic Cd exposure. •Duration of Cd exposure influenced biochemical biomarker responses in mussels. -- Abstract: The biochemical responses of the green-lipped mussel, Perna canaliculus, to waterborne cadmium (Cd) were investigated in order to delineate toxic mechanisms, and the impacts of exposure dose and duration, of this important toxicant in a potential sentinel species. Mussels were exposed for either 96 h (acute: 0, 2000, 4000 μg L{sup −1} Cd) or for 28 d (subchronic: 0, 200, 2000 μg L{sup −1} Cd), and the digestive gland, gill and haemolymph were examined for impacts. Biochemical responses measured included those associated with metal detoxification (metallothionein-like protein; MTLP), oxidative stress (catalase, lipid peroxidation), cellular homeostasis (alkaline phosphatase, Na{sup +}, K{sup +}-ATPase; NKA), and energy utilisation (glycogen, haemolymph protein). Following acute exposure, digestive gland glycogen and gill NKA activity were significantly altered by Cd exposure relative to levels in mussels exposed to Cd-free seawater. Subchronic Cd exposure resulted in a significant increase in MTLP levels in both the gill and the digestive gland. This increase was correlated strongly with the levels of Cd accumulation measured in these tissues (R = 0.957 for gill, 0.964 for digestive gland). Catalase activity followed a similar pattern, although the correlation with tissue Cd accumulation was not as strong (R = 0.907 for gill, 0.708 for digestive gland) as that for MTLP. Lipid peroxidation increased in the digestive gland at Days 7 and 14 at both subchronic Cd levels tested, but this effect had largely dissipated by Days 21 and 28 (with the exception of

    The natural chemical compounds radicicol, polygodial and ubiquinone-10 (Q10) have previously been identified as inhibitors of metamorphosis in ascidian larvae. Accordingly, they have potential as a specific remedy for the costly problem of fouling ascidians in bivalve aquaculture. In this study, these compounds were screened for their effects on the physiological health of an aquaculture species, the green-lipped mussel, Perna canaliculus Gmelin, at or above the 99% effective dose (IC(99)) in ascidians. Three physiological biomarkers of mussel health were screened: growth (increases in shell height and wet weight), condition (condition index) and mitochondrial respirational function (Complex I-mediated respiration, Complex II-mediated respiration, maximum uncoupled respiration, leak respiration, respiratory control ratios and phosphorylation system control ratios). While polygodial and Q10 had no effect on mussel growth or the condition index, radicicol retarded growth and decreased the condition index. Mitochondrial respirational function was unaffected by radicicol and polygodial. Conversely, Q10 enhanced Complex I-mediated respiration, highlighting the fundamental role of this compound in the electron transport system. The present study suggests that polygodial and Q10 do not negatively affect the physiological health of P. canaliculus at the IC(99) in ascidians, while radicicol is toxic. Moreover, Q10 is of benefit in biomedical settings as a cellular antioxidant and therefore may also benefit P. canaliculus. Accordingly, polygodial and Q10 should be progressed to the next stage of testing where possible negative effects on bivalves will be further explored, followed by development of application techniques and testing in a laboratory and aquaculture setting.

    Levels of 210 Po and its effective dose in green mussel (Perna viridis) collected from mussel farming area at the Samut Sakhon province during the period of 2012-2013 are presented. Several parameters including maximum shell length and the physiological performance of mussels using condition index and physical properties of seawater (pH, salinity, conductivity, TDS, DO and cation-anion elements) were measured. Each individual mussel was measured on its maximum shell length which was adopted as size class. The activity concentration of 210Po was determined spectroscopically through its 5.30 MeV alpha particle emission, using 209 Po as an internal tracer. The 210 Po activity concentration in mussels was found to vary between 1.044 and 6.951 Bq.kg-1 wet weight. The 210 Po concentration was higher in smaller sized classes (>35 mm) and lowest in larger ones (40-70 mm). This confirms that larger mussels have lower 210Po levels on a weight basis. The 210 Po body burden (activity per mussel) ranged from 1.035 to 17.183 mBq. Contrary to the 210 Po concentrations, results of the body burden revealed the lower activities in smaller sized mussels (>35 mm) and the higher in larger sized ones (40-70 mm). The type of fluctuations observed with 210 Po concentrations are interpreted as a seasonal effect. Total annual effective 210 Po dose due to mussel consumption was calculated to be in the range of 3.081 to 16.401 μSv. Based on the international guideline, the average dose calculated due to 210 Po in mussels of Samut Sakhon would not pose any significant radiological impact on human health and the mussels are considered to be safe for intake.

    Bivalves naturally exposed to toxic algae have mechanisms to prevent from harmful effects of diarrhetic shellfish poisoning (DSP) toxins. However, quite few studies have examined the mechanisms associated, and the information currently available is still insufficient. Multixenobiotic resistance (MXR) is ubiquitous in aquatic invertebrates and plays an important role in defense against xenobiotics. Here, to explore the roles of P-glycoprotein (P-gp) in the DSP toxins resistance in shellfish, complete cDNA of P-gp gene in the mussel Perna viridis was cloned and analyzed. The accumulation of okadaic acid (OA), a main component of DSP toxins, MXR activity and expression of P-gp in gills of P. viridis were detected after exposure to Prorocentrum lima, a dinoflagellate producing DSP toxins in the presence or absence of P-gp inhibitors PGP-4008, verapamil (VER) and cyclosporin A (CsA). The mussel P. viridis P-gp closely matches MDR/P-gp/ABCB protein from various organisms, having a typical sequence organization as full transporters from the ABCB family. After exposure to P. lima, OA accumulation, MXR activity and P-gp expression significantly increased in gills of P. viridis. The addition of P-gp-specific inhibitors PGP-4008 and VER decreased MXR activity induced by P. lima, but had no effect on the OA accumulation in gills of P. viridis. However, CsA, a broad-spectrum inhibitor of ABC transporter not only decreased MXR activity, but also increased OA accumulation in gills of P. viridis. Together with the ubiquitous presence of other ABC transporters such as MRP/ABCC in bivalves and potential compensatory mechanism in P-gp and MRP-mediated resistance, we speculated that besides P-gp, other ABC transporters, especially MRP might be involved in the resistance mechanisms to DSP toxins.

Nas crianças, podemos citar como exemplo, um quadro comum, a marcha com os "pés para dentro" ("toeing in" e nos indivíduos adultos, a incapacitante artrose degenerativa dos joelhos. Enquanto as alterações ósseas localizadas no plano transverso são difíceis de serem avaliadas, as deformidades presentes nos planos frontal e sagital podem ser avaliadas facilmente através, por exemplo, de simples radiografias. Neste contexto, dentre os métodos disponíveis para o estudo rotacional da perna, não há procedimento clínico ou de imagem que reúna as características de precisão, praticidade e baixo custo. Com o intuito de preencher esta lacuna, os autores apresentam um dispositivo para aferição clínica indireta do ângulo de torção da perna para indivíduos adultos e crianças. Neste artigo, procedeu-se a avaliação e a análise de 40 membros inferiores de cadáveres adultos humanos.

    Depuration has been used to eliminate microorganism and toxic chemical contaminants in bivalve. However, scientific research still needs to discover the effectiveness of depuration. This research aimed at assessing the best depuration effectiveness in decreasing mercury (Hg) concentration level in two species of bivalves, green mussel (Perna viridis L.) and blood cockle (Anadara granosa L.). The depuration treatments applied 1.5 ppm ozon, 0.5 ppm chitosan, hydrodynamic technique (1.3 m/s), combination between hydrodynamic-ozon, hydrodynamic-chitosan and ozon-chitosan. The experiment were conducted in mini aquaria for 60 minutes. Mercury concentration was measured in 10 g dry weight of green mussel (4.05±0.020 ppm) and blood cockle (3.27 ± 0.666 ppm). The result showed that mercury depuration were highly effective by combination of ozone-chitosan in green mussel (96.51%) and 1.5 ppm ozone in blood cockle (87.06%).

The inoculation was carried out in "in natura" and pre-cooked mussels for 30 min, and after that the mussels were kept for 10 hours at room temperature (25 ± 1 °C and under refrigeration (7 ± 1 °C. Six thermal treatments were evaluated: three using steam (5, 10 and 15 minutes and three in boiling water (5, 10 and 15 minutes, in order to find the best time/temperature binomial to provide pathogenic control. Yield and physical-chemical and sensory characteristics were evaluated. All thermal treatments were efficient to eliminate microorganisms in 2 logarithmic cycles. However, the boiling water treatments presented better results than the steam treatments. The physical-chemical and sensory analyses did not show statistical differences among the thermal treatments studied. The best performances were reached in the shortest times of heat exposure. Overall, the treatments in boiling water presented better results than the steam treatments.Buscando a qualidade do mexilhão Perna perna cultivado e comercializado no município de Ubatuba, SP, foram estudados o crescimento e o controle de Staphylococcus aureus e Bacillus cereus inoculados artificialmente em mexilhões in natura e pré-cozidos, mantidos por 10 horas à temperatura ambiente (25 ± 1 °C e sob refrigeração (7 ± 1 °C.

    It is unclear whether habitat degradation correlates with tolerance of marine invertebrates to abiotic stress. We therefore tested whether resistance to climate change-related stressors differs between populations of the green mussel Perna viridis from a heavily impacted and a mostly pristine site in West Java, Indonesia. In laboratory experiments, we compared their oxygen consumption and mortality under lowered salinity (-13 and -18 units, both responses), hypoxia (0.5 mg/l, mortality only) and thermal stress (+7 °C, mortality only). Mussels from the eutrophied and polluted Jakarta Bay showed a significantly smaller deviation from their normal oxygen consumption and higher survival rates when stressed than their conspecifics from the unaffected Lada Bay. This shows that human induced habitat degradation correlates with mussel tolerance to environmental stress. We discuss possible mechanisms - e.g. the selection of tolerant genotypes or habitat-specific differences in the nutritional status of the mussels - that could explain our observation.

    Green mussel or Perna viridis is filter feeder, which is very susceptible to heavy metals. It takes an effort to release heavy metal contents on the green shell, one of method that can be used to release heavy metal from green shell is depuration proccess. In this research, the depuration process was conducted by continues method of depuration, discontinues method by using various kind of water and acid extraction. The optimum time of continues depuration method is 1.5 hours, with circulation speed 250 L/h and result of Pb metal content decreased is equal to 30.048% and 29.748% for Cu. In the discontinues method, the optimum result was reached at 100oC by using PAM water as the media at 3 h immersion period with decrease of Pb metal content 35.001% and Cu metal content 39.015%. In the acid extraction method, the optimum condition was achieved by 11% acetic acid solvent with decreasing of Pb and Cu levels are 88.224% and 76.298%. For the determination of protein content, the decrease of protein content obtained by treatment with 11% acetic acid extract showed decrease of protein content 36.656% with Kjeldahl method.

    This study aims to test if RNA/DNA ratio and various energy reserve parameters (i.e., glycogen, lipid, protein content and total energy reserves) are sensitive biomarkers for indicating stresses induced by metal contaminants in the green-lipped mussel Perna viridis, a common organism for biomonitoring in Southeast Asia. This study was, therefore, designed to examine the effects of cadmium (Cd) and copper (Cu) on these potential biomarkers in two major energy storage tissues, adductor muscle (AM) and hepatopancreas (HP), of P. viridis after sub-lethal exposure to either metal for 10 days. The results showed that neither Cd nor Cu treatments affected the RNA/DNA ratio, glycogen and protein contents in AM and HP. As the most sensitive biomarker in P. viridis, the total lipid content in both AM and HP was significantly decreased in the treatment of 5μg Cu/L and 0.01-0.1μgCd/L, respectively. However, soft-tissue body burdens of Cu or Cd did not significantly correlate with each of the four biomarkers regardless of the tissue type. In addition, AM generally stored more glycogen than HP, whereas HP stored more lipids than AM. We proposed that multiple biomarkers may be employed as an integrated diagnostic tool for monitoring the health condition of the mussels. Copyright © 2016 Elsevier Inc. All rights reserved.

    This study aimed to reveal the proteomic responses in the hepatopancreas and adductor muscle of a common biomonitor, Perna viridis after 14-day exposure to two model chemicals, cadmium (Cd; a toxic metal) and hydrogen peroxide (H{sub 2}O{sub 2}; a pro-oxidant), using two-dimensional gel electrophoresis coupled with multivariate statistical analyses. Unique sets of tissue-specific protein expression signatures were revealed corresponding to the two treatment groups. In the hepatopancreas, 15 and 2 spots responded to Cd and H{sub 2}O{sub 2} treatments respectively. 6 and 7 spots were differentially expressed in the adductor muscle for Cd and H{sub 2}O{sub 2} treatments, respectively. 15 differentially expressed spots were successfully identified by MALDI-TOF/TOF MS analysis. These proteins are involved in glycolysis, amino acid metabolism, energy homeostasis, oxidative stress response, redox homeostasis and protein folding, heat-shock response, and muscle contraction modulation. This is the first time, to have demonstrated that Cd exposure not only leads to substantial oxidative stress but also results in endoplasmic reticulum stress in hepatopancreas of the mussel. Such notable stress responses may be attributable to high Cd accumulation in this tissue. Our results suggested that investigations on these stress-associated protein changes could be used as a new and complementary approach in pollution monitoring by this popular biomonitor species.

    We examined spatiotemporal variations of metal levels and three growth related biomarkers, i.e., RNA/DNA ratio (RD), total energy reserve (Et) and condition index (CI), in green-lipped mussels Perna viridis transplanted into five locations along a pollution gradient in the marine environment of Hong Kong over 120days of deployment. There were significant differences in metal levels and biomarker responses among the five sites and six time points. Mussels in two clean sites displayed better CI and significantly lower levels of Ag, Cu, Pb and Zn in their tissues than the other sites. Temporal patterns of RD in P. viridis were found to be site-specific. Across all sites, Et decreased in P. viridis over the deployment period, though the rate of decrease varied significantly among the sites. Therefore, temporal variation of biomarkers should be taken to consideration in mussel-watch programs because such information can help discriminate pollution-induced change from natural variation.

    Cadmium (Cd), mercury (Hg), arsenic (As), lead (Pb) and tin (Sn) concentrations were determined using ICP-MS in soft tissues (wet wt.) from whole greenshell mussels (Perna canaliculus) collected from Urapukapuka-Rawhiti Island, Opua Marina, Waitangi Bridge and Opua Wharf from the Bay of Islands, northern New Zealand (NZ). All samples had metal concentrations well below the Food Standards Australia and New Zealand (FSANZ) maximum limits and were comparable to, or less than, concentrations observed in previous NZ studies. Based on the average values detected in the current study, the concentrations of heavy metals ingested in a 'typical diet' containing greenshell mussels are below the provisional tolerable weekly intake (PTWI). However, Maori (indigenous people of New Zealand), Pacific Islanders and Asians consume a far greater quantity of seafood (and therefore heavy metals) than the general public of New Zealand and could potentially consume enough shellfish to exceed the PTWI for Cd (but not for Hg, As, Pb or Sn). Although our results, based on the current PTWIs, indicate no significant health risk to greenshell mussel consumers in this region, PTWIs change over time; concentrations which were thought to be safe are later found to be harmful. Additionally, differences in individual human susceptibilities to various toxins could increase the risk of harm for consumers with low tolerance to heavy metals. We suggest that a survey of the frequency, amount and species consumed by groups whose diet may be largely shellfish-based is required to enable a more comprehensive risk assessment to be made.

    A year-round study was conducted to assess the seasonal variations and potential influence of the riverine discharge from the Pearl River on biomarker responses in Hong Kong waters. A suite of biomarkers including antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), the lipid peroxidation product malondialdehyde (MDA), a Phase II detoxification enzyme glutathione-S-transferase (GST) and the neural transmitter enzyme acetylcholinesterase (AChE) in the green mussel, Perna viridis, were monitored from three coastal sites, Port Shelter, Tung Chung and Tai O, stretching from the east to the west of Hong Kong. Despite of the seasonal variations, the total protein profiles suggested that mussels from the three sites had a growth cycle that was in phase with each other. This implied that intrinsic variation between sites due to a different phase of growth was minimal. Seasonal variations of the biomarker responses in the mussels were found to be significant (Tukey multiple comparison test, pbiomarker responses at Tai O in relation to the extreme low salinity of 8‰. Mussels from the western site also revealed a higher oxidative stress than those from the eastern side throughout the year (Tukey multiple comparison test, pbiomarker responses. Gill tissues of the mussels were more advantageous for biomarker studies or monitoring because their protein levels were less sensitive to seasonal variations and they yielded a higher protein normalized biomarker response than the whole body tissues. This increases their discrimination ability for site comparisons. The feasibility of biomarker monitoring in areas of sub-lethal or low chemical contamination will also be discussed.

    Full Text Available The Chinese green mussel, Perna viridis, is a marine bivalve with important economic values as well as biomonitoring roles for aquatic pollution. Byssus, secreted by the foot gland, has been proved to bind heavy metals effectively. In this study, using the RNA sequencing technology, we performed comparative transcriptomic analysis on the mussel feet with or without inducing by cadmium (Cd. Our current work is aiming at providing insights into the molecular mechanisms of byssus binding to heavy metal ions. The transcriptome sequencing generated a total of 26.13-Gb raw data. After a careful assembly of clean data, we obtained a primary set of 105,127 unigenes, in which 32,268 unigenes were annotated. Based on the expression profiles, we identified 9,048 differentially expressed genes (DEGs between Cd treatment (50 or 100 μg/L at 48 h and the control, suggesting an extensive transcriptome response of the mussels during the Cd stimulation. Moreover, we observed that the expression levels of 54 byssus protein coding genes increased significantly after the 48-h Cd stimulation. In addition, 16 critical byssus protein coding genes were picked for profiling by quantitative real-time PCR (qRT-PCR. Finally, we reached a primary conclusion that high content of tyrosine (Tyr, cysteine (Cys, histidine (His residues or the special motif plays an important role in the accumulation of heavy metals in byssus. We also proposed an interesting model for the confirmed byssal Cd accumulation, in which biosynthesis of byssus proteins may play simultaneously critical roles since their transcription levels were significantly elevated.

    Marine environmental samples including seawater (filtered and unfiltered), suspended particles, and green mussels (Perna viridis) were collected from Sriracha and Angsira areas located in Chonburi province in order to determine Po-210 radioactivity. The former was chosen because it is generally believed that this area has been contaminated by one of the largest industrial estates in Thailand and others human-activities (non-nuclear activities) nearby such as oil refineries and Coal Power Plants. Discharges, ashes, and wastes released from these activities may result in an increase of Po-210 concentration in marine environment when compared to other areas. The later was designated to serve as a control site in this study since this area is unlikely to be impacted by industrial activities. Our results revealed that, in the filtered seawater, averaged values of Po-210 level were 0.26 + 0.14 mBq/L (Sriracha) and 0.56 + 0.42 mBq/L (Angsira) and, in the unfiltered seawater, means of Po-210 radioactivity were 2.37 + 0.32 mBq/L (Sriracha) and 4.20 + 2.78 mBq/L (Angsira). Furthermore, the suspended particles contained Po-210 concentrations with averaged values of 14.11 + 8.87 Bq/kg dw (Sriracha) and 102.21 + 51.49 Bq/kg dw (Angsira) while averaged Po-210 levels of 35.74 + 17.53 Bq/kg dw (Sriracha) and 71.12 + 62.88 Bq/kg dw (Angsira) were found in the green mussels examined. The present finding indicates that there is no radiological impact caused by those human activities to the marine environment at Sriracha. Radiation dose assessment was also performed in both the green mussels and human who consume green mussels. The results show that the green mussels farmed at Sriracha and Angsira received averaged radiation dose rates from Po-210 at 0.0007 and 0.0015 mGy/d, respectively. In addition, our results reveal that populations living in Chonburi province and ingesting the green mussels from these 2 locations received radiation dose rates from Po-210 at the means of 44.25 and

    Full Text Available Este artigo contém as conclusões de reunião de 17-18 de novembro de 2006 do Grupo Brasileiro de Estudo em Síndrome das Pernas Inquietas (GBE-SPI sobre diagnóstico e tratamento de SPI. Reiterou-se que se trata de condição de diagnóstico exclusivamente clínico, caracterizada por sensação anormal localizada, sobretudo, mas não exclusivamente, em membros inferiores, com piora noturna e alívio por movimentação da parte envolvida. Agentes terapêuticos com eficácia comprovada por estudos classe I são agonistas dopaminérgicos, levodopa e gabapentina enquanto que ácido valpróico de liberação lenta, clonazepam, oxicodona e reposição de ferro têm eficácia sugerida por estudos classe II. As recomendações do GBE-SPI para manejo de SPI primária são medidas de higiene do sono, suspensão de agentes agravantes de SPI, tratamento de comorbidades e agentes farmacológicos. Para estes as drogas de primeira escolha são agentes dopaminérgicos; segunda escolha são gabapentina ou oxicodona; e terceira escolha são clonazepam ou ácido valpróico de liberação lenta.This article contains the conclusions of the November 17-18, 2006 meeting of the Brazilian Study Group of Restless Legs Syndrome (GBE-SPI about diagnosis and management of restless legs syndrome (RLS. RLS is characterized by abnormal sensations mostly but not exclusively in the legs which worsen in the evening and are improved by motion of the affected body part. Its diagnosis is solely based on clinical findings. Therapeutic agents with efficacy supported by Class I studies are dopamine agonists, levodopa and gabapentine. Class II studies support the use of slow release valproic acid, clonazepan and oxycodone. The GBE-SPI recommendations for management of SPI are sleep hygiene, withdrawal of medications capable of worsening the condition, treatment of comorbidities and pharmacological agents.

Previous articles have shown that the frequency of RLS is higher in migraine patients than in controls. We conducted a study to evaluate comorbidities, medication used and depressive symptoms that can explain the relation between migraine and RLS. METHODS: A case-control study was performed in which patients with migraine (n=72 and a control group without migraine (n=72 were interviewed. Data including RLS diagnosis, depressive symptoms, comorbidities and drugs used were evaluated. RESULTS: There was a significant association between migraine and RLS (p=0.01, but comorbidities such as diabetes, hypertension, anemia and drugs used did not explain this association. Depression scores, as measured by the Beck Depression Inventory, were higher in migraine patients with RLS (p =0.04.

Havia relato de traumatismo de crânio há 34 anos e coma de 2 meses de duração. A vídeo-polissonografia revelou comportamento agressivo e agitado durante o sono REM, e movimentos periódicos de pernas. Havia importante sonolência diurna no teste de latências de sono. Foi instituído tratamento com levodopa-benzerazida 100/25 mg à noite. Após 10 semanas de evolução, houve melhora da movimentação noturna global, e desaparecimento dos episódios ligados a sonhos de conteúdo violento.

His wife informed that for the past ten years the patient had presented intense and aggressive body movements, and sometimes, violent dreams. The patient also complained of excessive daytime sleepiness. His relevant previous medical history included a traumatic brain injury at the age of 28 which left him in coma for two months. A video-polysomnography showed periodic leg movements and, during REM sleep, aggressive and agitated behaviour. The multiple sleep latency test revealed extremely short latencies. Initially, he was treated with levodopa-benzerazide, 100/25 mg, 2 hours before bedtime. After 10 weeks his overnight behaviour pattern improved and leg movements diminished.

    The use of certified reference materials in chemical analysis is an important requirement in quality assurance systems, as it allows the validation of analytical methods and the realization of the metrological traceability of results. Then, it is possible to obtain valid and comparable results not only in space, but also in time. In this study, all the steps for the preparation of a national mussel reference material were attained, from the collection of the bulk material to processing steps such as freeze-drying, grinding, bottling and sterilization. Internationally accepted principles were applied for the homogeneity and stability assessment of the material, using instrumental neutron activation analysis and atomic absorption spectrometry as analytical techniques. By means of a collaborative program with participation of Brazilian and foreign laboratories, the chemical characterization of the material was performed. Element content in the mass percentage to mg kg -1 range was determined for 47 elements and some radionuclides, naturally present in the material. With the application of suitable statistical treatment to the data, it was considered that the content of 11 of those elements may be certified: As, Ca, Cl, Co, K, Mg, Mn, Na, Se, Th and Zn. This study may be considered an important step in the national metrological development, as it shows that the production and characterization of biological reference materials, mussel in particular, is feasible in Brazil, as a tool for quality assurance of environmental and nutritional studies performed in the country.

    Full Text Available BACKGROUND & PURPOSE: The association of obstructive sleep apnea syndrome (OSAS and restless legs syndrome (RLS has been reported in the literature for many years. Both conditions may be responsible for fatigue and somnolence complaints secondary to nocturnal sleep disruption. The primary concern of this study is to evaluate the outcome of fatigue and daytime sleepiness symptoms at baseline and after continuous positive air pressure (CPAP treatment in OSAS patients with and without RLS. METHOD: A prospective and comparative study between a group of 13 patients with OSAS and a group of 17 patients with OSAS+RLS. Laboratory blood tests and polysomnography were performed at baseline. The Epworth Sleepiness Scale (ESS and the Pichot’s questionnaire of fatigue/depression (PIC were applied before and after 3 months of CPAP treatment. Results were compared. RESULTS: No significant differences were found on PSG and laboratory results at baseline. Both groups had similar ESS and PIC scores at baseline (p=0.73 and 0.08, respectively. After n-CPAP, OSAS+RLS patients showed higher ESS and PIC scores (p=0.017 and 0.03, respectively. CONCLUSIONS: Despite a favorable general response, n-CPAP seemed less effective in treating fatigue and sleepiness in the OSAS+RLS group.OBJETIVO: A associação síndrome de apnéia obstrutiva do sono / síndrome de pernas inquietas (SAOS-SPI tem sido mencionada na literatura há muito.

Dentre as 12 espécies de Vibrio identificadas destacaram-se como de maior prevalência as espécies Vibrio alginolyticus, V. cholerae não-O1, V. parahaemolyticus, V. carchariae e Vibrio vulnificus. A relevância epidemiológica destes patógenos associada a casos de gastrenterite humana após consumo de mexilhões crus ou parcialmente cozidos, reforça a importância de alertar as autoridades de Vigilância Sanitária sobre sua presença na cadeia alimentar e seus riscos para a Saúde Pública.The microbiology analysis of mussels reflects the aquatic environment quality because these animals retain various pathogens such as Vibrionaceae family microorganisms in their organism. In the present investigation, we evaluated the presence of Vibrio spp. in mussels (in natura and precooked commercialized at an Experimental Station Mussel Culture in Jurujuba, Niterói, Rio de Janeiro. A total of 86 samples were analyzed using the enrichment in Alkaline Peptone Water (APW added to 1 and 3% of NaCl, isolated in Thiossulfate Citrate Bile Sucrose Agar (TCBS and confirmed that there were suspect colonies by biochemical tests. The results showed the identification of 12 different Vibrio species whereby Vibrio alginolyticus, V. cholerae non-O1, V. parahaemolyticus, V. carchariae and V. vulnificus were the prevalent species. The epidemiological relevance of these pathogens associated with cases of human gastroenteritis after in natura or precooked mussels show the need to alert Sanitary Officials about their presence in the food chain and their risks to Public Health.

    The current study was carried out from May 2014 to April 2015 to estimate the stock status of P. viridis in Marudu Bay. The gonad development was monitored by histological examination, while the population parameters including asymptotic length ( L ∞), growth coefficient ( K), mortality rate ( Z, F and M), exploitation level ( E) and recruitment of P. viridis were estimated using the lengthfrequency data. Results of the current study demonstrated that P. viridis in Marudu Bay spawned throughout the year with two major peaks, one in April to May and another one in October to December. The recruitment pattern was continuous with the peak in May to June 2014, which corresponded to the first spawning peak in April. However, no significant recruitment was observed from the second spawning peak due to the difference in spawning timing between male and female populations. The estimated asymptotic length ( L ∞), growth coefficient ( K), total mortality ( Z), natural mortality ( M), fishing mortality ( F) and growth performance ( φ) of P. viridis in Marudu Bay were estimate to be 117 mm, 0.97 yr-1, 4.39 yr-1, 1.23 yr-1, 3.16 yr-1 and 4.123, respectively. The exponent b of the lengthweight relationship was 2.4 and exploitation level ( E) was 0.72. The high mortality, low condition indices and negative allometric of P. viridis in Marudu Bay is caused by a lack of suitable food in the surrounding water.

    Full Text Available A green-lipped mussel (GLM preparation was evaluated in a randomized, double-controlled and double-blinded clinical trial. It was hypothesized that the treatment effect would be less than that of the positive control (carprofen but more than that of the negative control (placebo. Forty-five dogs with chronic pain and a radiographic diagnosis of osteoarthritis that were randomly allocated into one of three groups completed the study. All dogs were fed the test products or placebo for 8 weeks. The dogs were evaluated four times, at 4-week intervals. Six different variables were assessed: veterinary-assessed mobility index, two force plate variables, owner-evaluated chronic pain index and pain as well as locomotion visual analogue scales (VASs. Intake of extra carprofen was also evaluated. A chi-squared and a Mann–Whitney test were used to determine significance between groups. When changed to dichotomous variables, there were more dogs in the GLM than in the placebo group that improved, according to veterinary-assessed mobility, owner-evaluated chronic pain index and pain VAS (P = 0.031, P = 0.025, P = 0.011, respectively. For the same three, the odds ratio and their confidence interval were over one. The extent of improvement was significantly different between the GLM and the control in veterinary-assessed mobility (P = 0.012 and pain VAS (P = 0.004. In conclusion, GLM alleviated chronic orthopedic pain in dogs although it was not as effective as carprofen. As no side-effects were detected, GLM may be beneficial in dogs e.g. when non-steroidal anti-inflammatory drugs cannot be used.

    Conventional denitrification and anaerobic ammonium oxidation (anammox) contributes to nitrogen loss in oxygen-deficient systems, thereby influencing many aspects of ecosystem function and global biogeochemistry. Mejillones Bay, northern Chile, presents ideal conditions to study nitrogen removal processes, because it is inserted in a coastal upwelling system, its sediments have anoxia and hypoxia conditions and under the influence of the Oxygen Minimum Zone (OMZ), unknown processes that occur there and what are the microbial communities responsible for their removal. Microbial communities associated with coastal sediments of Mejillones Bay were studied by denaturing gel electrophoresis (DGGE) and fluorescence in situ hybridization (FISH), by incubation experiments with 15 N isotope tracers were studied nitrogen loss processes operating in these sediments. DGGE analysis showed high bacterial diversity, certain redundant phylotypes and differences in community structure given by the depth; this reflects the microbial community adaptations to environmental conditions. A large fraction (up to 70%) of DAPI-stained cells hybridized with the bacterial probes. Nearly 52-90% of the cell could be further identified to know phyla. Members of the Cytophaga-Flavobacterium cluster were most abundant in the sediments (13-26%), followed by Proteobacteria. Isotopic tracer experiments for the sediments studied indicated that nitrogen loss processes that predominated were performed by denitrifying communities (43.31-111.20 μMd -1 ) was not possible to detect anammox in the area and not anammox bacteria were detected

    Full Text Available Úlceras venosas são comuns na população adulta, causando significante impacto social e econômico devido a sua natureza recorrente e ao longo tempo decorrido entre sua abertura e cicatrização. Quando não manejadas adequadamente, as úlceras venosas têm altas taxas de falha de cicatrização e recorrência. Apesar da elevada prevalência e da importância da úlcera venosa, ela é freqüentemente negligenciada e abordada de maneira inadequada. Esta revisão discute abordagem diagnóstica e terapêutica das úlceras venosas. O diagnóstico clínico baseia-se em história e exame físico, com ênfase nos sinais e sintomas associados e palpação dos pulsos dos membros inferiores. A ultra-sonografia Doppler deve ser utilizada para determinar o índice pressórico entre o tornozelo e o braço, e exames não invasivos, como o duplex scan, devem ser realizados para avaliar o sistema venoso superficial, profundo e perfurante. Para abordagem terapêutica são fundamentais os diagnósticos clínico e laboratorial corretos, além do diagnóstico e tratamento adequados das complicações das úlceras crônicas. Os esforços devem ser direcionados para a cicatrização da úlcera e, posteriormente, para evitar as recidivas. O grande avanço no conhecimento da fisiopatogenia das úlceras venosas tem permitido o desenvolvimento de novas modalidades de tratamento clínico e cirúrgico.Venous ulcers are common in adult population. They cause significant socioeconomic impact due to recurrence and the long interval between onset and healing. If venous ulcers are not appropriately managed, they present high rates of healing failure and recurrence. Despite their high prevalence and importance, venous ulcers are often neglected and inadequately managed. This review discusses diagnosis and therapy of lower limb venous ulcers. Clinical diagnosis is based on history and physical examination, emphasizing associated signs and symptoms, and pulse palpation of lower limbs. Doppler must be used to determine the ankle-arm index, and non-invasive exams, such as duplex scan, are requested to evaluate the superficial, deep and perforating venous systems. Accurate clinical and laboratory diagnosis of venous ulcers, as well as appropriate treatment of their complications are fundamental for successful therapy. Efforts must be directed towards healing and avoiding recurrences. Advanced knowledge on the venous ulcer physiopathogenesis has led to development of new clinical and surgical treatments.

    Full Text Available The Procyon cancrivorus, as well as its entire family, is an endemic species of the Americas. It is widely found throughout the Brazilian territory and it inhabits all biomes, particularly the cerrado. This study used five adult specimens of P. cancrivorus for the characterization of the leg muscles. The animals were collected on roads (i. e. they had been killed by accident. The muscles were dissected, observing their proximal and distal insertions macroscopically, together with their topographic relationships to the arteries and nerves. The muscles studied are considered muscles of the tibia. The cranial tibial muscles, brevis, longus, long digital extensor and lateral extensor digitorum are craniolaterally distinct in the tibia, and the gastrocnemius muscles, lateral flexor of the fingers, popliteus, flexor digitorum, flexor digitorum and medial tibial flow are located in the caudal region of the tibia. The muscles of this group act as flexors and extensors of the hock joint and as flexors and extensors of the digital joints, except the popliteal muscle that acts as a flexor of the knee joint. The muscles studied were compared with their muscles in domestic carnivores, like the dog and cat, and great similarity was found.

    2011-10-01

    Greenshell™ mussels are New Zealand's largest seafood export species. Some export markets require compliance with 'zero' tolerance legislation for Listeria monocytogenes in 25 g of product. Even though individually quick frozen (IQF) mussel products are labeled 'to be cooked', and are not classified as ready-to-eat, some markets still require them to comply with the strict policy. Three mussel processing plants were assessed for the pattern of L. monocytogenes contamination on raw material, environment, food contact surfaces, and in the final product. Cultures (n = 101) obtained from an industrial Listeria monitoring program from August 2007 to June 2009 were characterized by serotyping and pulsed field gel electrophoresis. Using the crystal violet method, isolates were assessed for their ability to form biofilms. This work confirmed the presence of L. monocytogenes in raw and processed product, and the importance of cross-contamination from external and internal environments. Processing plants had L. monocytogenes pulsotypes that were detected more than once over 6 months. No correlation was found between biofilm-forming ability and persistent isolates. Two pulsotypes (including a persistent one), were previously isolated in human cases of listeriosis in New Zealand, but none of the pulsotypes matched those involved in international outbreaks.

    Full Text Available Se determinó la concentración de Cu, Cd, Ni y Zn en sedimentos intermareales y Emérita analoga (Stimpson, 1857, en ocho sectores de la bahía de Mejillones del sur, Chile. Sólo el Zn presentó un cierto grado de contaminación en los sedimentos de la bahía con un índice de geoacumulación de 2,8. Al analizar el contenido de metales en E. analoga, se determinó que esta especie estaría bioacumulando algunos de los metales analizados pero en baja magnitud, a excepción del Zn con un factor de bioacumulación de 2,07. El dendrograma de similitud realizado con datos del índice de bioacumulación, relacionó los valores de este índice con la distribución espacial de las principales industrias y zonas urbanas. Esta concordancia permite establecer que E. analoga estaría respondiendo como un indicador de la salud ambiental para este sistema. Además, es importante destacar que esta bahía está experimentando los primeros indicios de una zona industrial moderadamente impactada. Por lo tanto, es necesario realizar mediciones constantes, que abarquen más de una matriz ambiental, para controlar el impacto antrópico en este ecosistema marino costero altamente productivo.

    Full Text Available Se midió la concentración de carbono total, nitrógeno total, azufre total, materia orgánica, Ni, Cd, Pb, Cu y Zn en sedimentos costeros (10 m de profundidad de columna de agua de ocho sectores de la bahía Mejillones. La composición elemental de los sedimentos sería el resultado de la abundante materia orgánica autóctona presente en este sistema costero. El orden de abundancia de los metales analizados fue: Zn > Cu > Ni > Pb > Cd. La concentración de metales no se explicaría por el contenido de materia orgánica ni la composición granulométrica de los sedimentos costeros. La evaluación del contenido de metales en los sedimentos, mostró que el Ni, Zn y Pb estarían levemente enriquecidos en la actualidad, aún cuando los valores se mantienen dentro de un rango cercano a los niveles preindustriales. El análisis del dendrograma de similitud de los sectores de estudio separó la línea de costa de Mejillones en dos grandes zonas; una asociada a la actividad industrial desarrollada en la bahía, y otra correspondiente al área de desarrollo urbano de Mejillones con características similares a aquellos ambientes libres de actividad antrópica directa.The total carbon, total nitrogen, total sulphur, organic matter, Ni, Cd, Pb, Cu, and Zn concentrations were measured in coastal sediments (10 m water depth at eight stations in Mejillones Bay. The elemental composition of these sediments is a function of the autochthonous organic matter generated in this coastal system. The order of abundance for the metals was: Zn > Cu > Ni > Pb > Cd. The metal content is not explained by the organic matter content or grain size of these coastal sediments. The evaluation of the concentration metals in the sediments showed that Ni, Zn, and Pb are slightly enriched at the present, although with values that are similar to preindustrial concentrations. A cluster analysis of the similarity in the study area separated the Mejillones coast into two main zones

    Nodularia spumigena periodically proliferates to cause toxic algal blooms with some aquatic animals enduring and consuming high densities of the blue green algae or toxic lysis. N. spumigena contains toxic compounds such as nodularin and lipopolysaccharides. This current work investigates physiological effects of exposure from bloom conditions of N. spumigena cells and a post-bloom lysis. Biochemical and antioxidative biomarkers were comparatively studied over an acute 3-day exposure. In general, a post-bloom N. spumigena lysis caused opposite physiological responses to bloom densities of N. spumigena. Specifically, increases in glutathione (GSH) and glutathione peroxidase (GPx) and decreases in glutathione S-transferase (GST) were observed from the N. spumigena lysis. In contrast, N. spumigena cell densities decreased GSH and increased GST and lipid peroxidation (LPO) in mussels. Findings also suggest that at different stages of a toxic bloom, exposure may result in toxic stress to specific organs in the mussel

    Full Text Available Osteoarthritis (OA typically generates pain, reduced mobility and reduced quality of life. Most conventional treatments for osteoarthritis, such as non-steroidal anti-inflammatory drugs (NSAIDs and simple analgesics, have side effects. PCSO-524™, a non polar lipid extract from the New Zealand Green Lipped Mussel, is rich in omega-3 fatty acids and has been shown to reduce inflammation in both animal studies and patient trials. This OA trial examined pain relief changes in relation to quality of life and safety of use for OA patients who took PCSO-524™ compared with patients who took fish oil (containing an industry standard EPA-18% and DHA-12% blend. PCSO-524™ patients showed a statistically significant improvement compared with patients who took fish oil. There was an 89% decrease in their pain symptoms and 91% reported an improved quality of life. Patients treated with fish oil showed significantly less improvement and a greater level of physical discomfort during the study. These results suggest that PCSO-524™ might offer a potential alternative complementary therapy with no side effects for OA patients.

    Full Text Available Green mussel is one of important species cultured in Lada Bay, Pandeglang. To provide a necessary guidance regarding green mussel mariculture development, finding suitable site is an important step. This study was conducted to identify suitable site for green mussel mariculture development using geographic information system (GIS based models. Seven important parameters were grouped into two submodels, namely environmental (water temperature, salinity, suspended solid, dissolve oxygen, and bathymetry and infrastructural (distance to settlement and pond aquaculture. A constraint data was used to exclude the area from suitability maps that cannot be allowed to develop green mussel mariculture, including area of floating net fishing activity and area near electricity station. Analyses of factors and constraints indicated that about 31% of potential area with bottom depth less than 25 m had the most suitable area. This area was shown to have an ideal condition for green mussel mariculture in this study region. This study shows that GIS model is a powerful tool for site selection decision making. The tool can be a valuable tool in solving problems in local, regional, and/or continent areas.

    Full Text Available Entre junio de 2002 y abril de 2003 se midió el contenido de cadmio total y disuelto entre la superficie y los 100 m de profundidad, en dos estaciones localizadas en la bahía Mejillones del Sur. El rango de cadmio total y cadmio disuelto en las aguas de esta bahía fue 0,41-10,7 y 0,08-1,61 nM, respectivamente, durante el período de muestreo. Los resultados fueron correlacionados con la estructura físico-química de la columna de agua al momento del muestreo, de manera de estudiar los patrones de variabilidad estacional de este metal en este sistema de surgencia. Las condiciones oceanográficas imperantes durante este período correspondieron a un año normal (no-El Niño. Las masas de agua presentes en la bahía correspondieron a agua subantártica, subtropical y ecuatorial subsuperficial, con diferentes grados de mezcla y estratificación durante el período de estudio. Los perfiles de cadmio presentaron una distribución vertical clásica de un micronutriente. Sin embargo estos perfiles presentaron leves diferencias que pueden ser atribuidas a la condición de mezcla de las masas de agua al interior de la bahía. Un análisis multivariado de los parámetros registrados indicó que la variación temporal de cadmio en las aguas superficiales está asociada a las fluctuaciones de la clorofila a y la temperatura. Esto sugiere que, a escala estacional, la producción de biomasa fitoplanctónica sería el principal factor que controla la distribución de cadmio en esta bahía. Por otro lado, a pesar de que el cadmio es un metal redox sensitivo no se encontró un efecto significativo de la disponibilidad de oxígeno sobre el comportamiento de este metal, de manera que la condición micróxica de las aguas de fondo de la bahía no sería un factor preponderante en el flujo de cadmio hacia los sedimentos. La razón Cd/PO4 encontrada en Mejillones es similar a la reportada en otras zonas costeras de Chile. Los bajos valores y la tendencia temporal

Adicionalmente, los parámetros físicos medidos (contenido de agua, densidad seca, susceptibilidad magnética, rayos-X y escala de grises contribuyeron a la caracterización de los sedimentos. El testigo recuperado con un sacatestigo de caja (Testigo 3; 23°03' S, 70°27' W; 80 m de profundidad de la columna de agua registró una tasa de sedimentación de 0,18 cm año-1 (basada en mediciones de 210Pb. La extrapolación de esta tasa de sedimentación a la base del testigo da cuenta de una edad de ~223 años. Los sedimentos se caracterizaron por presentar una sucesión de láminas claras y oscuras de grosor milimétrico, que se diferencian tanto en sus propiedades físicas como en la composición. Así las láminas oscuras, de mayor densidad y menor contenido de agua, representarían períodos de mayor productividad fitoplanctónica mientras que las láminas claras, de menor densidad y mayor contenido de agua, reflejarían períodos de menor productividad, concordando con estudios previos. La buena preservación de las láminas, lajiusencia de estructuras asociadas a procesos de bioperturbación, y los altos valores del δ15N sedimentario ( = 11,37 %¿ sugieren que los niveles de oxígeno en el agua de fondo de la bahía han permanecido bajos durante el período de dos siglos de depositación de los sedimentos reportados aquí. Nuestro registro se divide en dos grandes intervalos de productividad: un intervalo de menor productividad fitoplanctónica, antes de AD 1820, asociado a condiciones relativamente más cálidas en al área de surgencia, y otro de mayor productividad y altamente variable, a partir de AD 1877, relacionado con condiciones relativamente

    Full Text Available Parámetros geoquímicos (carbono orgánico, sílice biogénica y cadmio y petrográficos (materia orgánica estudiados en un testigo de sedimento de la Bahía Mejillones del Sur fueron utilizados para inferir variaciones en la productividad biológica superficial y la oxigenación subsuperficial durante los últimos 2.000 años. Este estudio demuestra que al interior de la bahía la productividad ha disminuido hacia el presente mientras que la Zona de Mínimo Oxígeno se ha intensificado. Se plantea que las variaciones de la productividad se deben a un desplazamiento del centro de surgencia de Punta Angamos, más cerca o más lejos de la bahía y/o a cambios en su intensidad asociados al régimen de vientos locales. Por su parte, la oxigenación estaría influenciada por el ascenso o descenso de la Zona de Mínimo Oxígeno presente en el área. Una correlación de estos resultados con estudios de bioindicadores realizados en otros testigos de la Bahía Mejillones permiten reforzar la hipótesis de que eventos como la Pequeña Edad del Hielo y el Episodio Cálido de la Edad Media han quedado registrados en esta bahía del norte de Chile. Según el presente estudio, el primer periodo estaría caracterizado por un aumento de la productividad superficial y un descenso en la oxigenación subsuperficial de la bahía, mientras que el segundo periodo presentaría características opuestas.Geochemical (organic carbon, biogenic silica and cadmium and petrographic (organic matter parameters analyzed in a sediment core of Mejillones del Sur Bay, have been used to reconstruct past variations in superficial biological productivity and subsuperficial oxygenation, during the last 2,000 years. This study tends to demonstrate that into the bay, the productivity has diminished up to the present, while the Oxygen Minimum Zone has intensified. Productivity variations can be attributed to changes in the upwelling intensity associated to changes in local wind system

    Distribution of pandemic strains of Vibrio parahaemolyticus in seafood, particularly in molluscan shellfish, and their serological and molecular relationships to clinical strains were examined from Hat Yai City in southern Thailand.

The isolates included 12 pandemic strains (tdh+, trh-, group-specific PCR positive) from five Oriental hard clam samples, five green mussel samples, and one bloody clam sample. Among the pandemic strains, eight belonged to serogroup O3:K6, three belonged to O1:K25, and one was O1:K untypeable. One hundred eighty-seven strains of V. parahaemolyticus were isolated from clinical specimens obtained from a hospital in this city during 2000 to 2001. The pandemic strains comprised 64 and 68% of the isolates in 2000 and 2001, respectively. Among the serotypes of the pandemic strains, O3:K6 was dominant at 73% in 2000 and 76% in 2001 followed by O1:K25 at 20% in 2000 and 13% in 2001. Pulsed-field gel electrophoresis profiles of the pandemic strains from molluscan shellfish were indistinguishable or very similar to those of patient isolates. Similarity of the serotype distribution and DNA fingerprints occurring between the molluscan shellfish strains and clinical strains suggests that molluscan shellfish may be an important source of pandemic V. parahaemolyticus infection in southern Thailand. For public health, proper cooking of molluscan shellfish in this area is strongly recommended.

  19. Paralytic Shellfish Poisoning (PSP in Margarita Island, Venezuela

    Full Text Available A severe outbreak of Paralytic Shellfish Poisoning (PSP occurred in Manzanillo and Guayacán, northwestern coast of Margarita Island, Venezuela, between August and October 1991. A bloom of dinoflagellates including Prorocentrum gracile, Gymnodinium catenatum and Alexandrium tamarense seemed to be responsible for this outbreak. Levels of PSP toxins in mussels (Perna perna exceeded the international safety limit of saxitoxin, 80 µg STX/100 g meat. PSP toxin values varied between 2 548 and 115 µg STX/100 g meat in Manzanillo, and between 1 422 and 86 µg STX/100 g meat in Guayacán. At both locations, the highest levels were detected in August, when 24 patients exhibited typical symptoms of PSP toxicity after consuming cooked mussels (16 required hospitalization. A high pressure liquid chromatographic (HPLC procedure was recently used on the 1991 samples. The major toxin detected in samples of both locations was decarbamoyl saxitoxin (dcSTX, but low concentrations of saxitoxin were also found in Manzanillo samples. Gonyautoxins GTX1, GTX2 and GTX3 were detected only at Guayacán, while in both locations, decarbamoylgonyatouxin (dcGTX2,3 toxins were detected. These findings represent the first time that causative toxins of PSP in Venezuela have been chemically identified, and confirm the presence of dcSTX and dcGTX in mussels from the Caribbean Sea. The presence of dcSTX and dcGTX in shellfish is indicative that Gymnodinium catenatum was a causative organism for outbreak of PSPUn severo brote de intoxicación paralizante por moluscos (PSP en inglés ocurrió en Manzanillo y Guayacán en la costa noroeste de la Isla de Margarita, Venezuela entre agosto y octubre de 1991.

    Full Text Available Durante el verano austral de 2003-2004, se estudiaron las propiedades del material particulado que sedimenta en la bahía Mejillones del Sur, y la estructura físico-química de la columna de agua. Se encontraron aguas más cálidas y oxigenadas en la superficie, una clara estratificación entre 10 y 20 m de profundidad y aguas más frías, densas y subóxicas bajo los 30 m y hasta el fondo durante el periodo de estudio. La bahía se caracterizó por la interacción de tres masas de aguas: Agua Superficial Subtropical (ASST, Agua Subantártica (ASSA, Agua Subsuperficial Ecuatorial (AESS. Se puso en evidencia que eventos moderados y cortos de surgencia con duración entre tres a ocho días alternan con períodos más prolongados de estratificación de 29 días. Durante los eventos débiles de surgencia y en el inicio del evento de estratificación prevalecieron condiciones subóxicas a microóxicas con concentraciones de nutrientes más elevados en el estrato de los 10 a 15 m de profundidad. La variabilidad de los niveles de saturación de oxígeno disuelto (OD y de nutrientes con las concentraciones de nitrógeno (N, fósforo (P y ácido silícico (Si, y las razones de N:P y Si:NID en la superficie, indicaron la presencia de una dinámica importante de los procesos de reciclaje de la materia orgánica en la columna de agua, y del aporte alóctono de nutrientes durante la surgencia. Las variaciones quincenales de los flujos totales del material particulado colectado con trampas instaladas en la bahía, sugieren que la sedimentación del material en la columna de agua se encuentra gobernada por la alternancia entre los períodos de surgencia y de estratificación. Además en las trampas de sedimentación se observó un patrón de empobrecimiento de nitrógeno en función de la profundidad, lo que sugiere condiciones de remineralización y desnitrificación en las aguas oxido-reductoras de fondo de esta bahía.This study addresses the spatial and

    Full Text Available The reproductive biology of Aegla caslro Schmitt, 1942 from Buraco do Padre, Ponta Grossa, Paraná State, was analyzed. The sampling was done monthly, from February/97 to January/98 with aid of hand net and screens at three stations, under an effort of 120 minutes. The mean air temperature ranged from 15.0ºC (May, July, September and October to 24.3ºC (December and January, and the water temperature from 15.8ºC (July to 22.3ºC (December. The dissolved oxygen oscillated from 95.7% (March to 100.2% saturation (August and the pH from 6.1 (July to 7.2 (September. A total of 827 specimens were obtained among which 384 males, 311 females and 132 juveniles. Males predominated over females, but the sex ratio followed the standard model of 1:1. Juveniles were found during all the study period, except in May and September. The peaks of their frequency curve occurred in April and December. The reproduction is discontinuous type with greater intensity in the colder months, from May to October. The females take part of the reproduction for two consecutive years and the species longevity was estimated in two years. The carapace length of the various development stages ranged as following: juveniles < 6.4 mm, immature females and males = from 6.5 to 12.2 mm and mature females and males = from 12.3 to 29.5 mm.

  20. Love thy neighbour: group properties of gaping behaviour in mussel aggregations.

    Directory of Open Access Journals (Sweden)

    Katy R Nicastro

    Full Text Available By associating closely with others to form a group, an animal can benefit from a number of advantages including reduced risk of predation, amelioration of environmental conditions, and increased reproductive success, but at the price of reduced resources. Although made up of individual members, an aggregation often displays novel effects that do not manifest at the level of the individual organism. Here we show that very simple behaviour in intertidal mussels shows new effects in dense aggregations but not in isolated individuals. Perna perna and Mytilus galloprovincialis are gaping (periodic valve movement during emersion and non-gaping mussels respectively. P. perna gaping behaviour had no effect on body temperatures of isolated individuals, while it led to increased humidity and decreased temperatures in dense groups (beds. Gaping resulted in cooler body temperatures for P. perna than M. galloprovincialis when in aggregations, while solitary individuals exhibited the highest temperatures. Gradients of increasing body temperature were detected from the center to edges of beds, but M. galloprovincialis at the edge had the same temperature as isolated individuals. Furthermore, a field study showed that during periods of severe heat stress, mortality rates of mussels within beds of the gaping P. perna were lower than those of isolated individuals or within beds of M. galloprovincialis, highlighting the determinant role of gaping on fitness and group functioning. We demonstrate that new effects of very simple individual behaviour lead to amelioration of abiotic conditions at the aggregation level and that these effects increase mussel resistance to thermal stress.

    Gulf of Paria exceeded local maximum permissible levels (Cu =20 µg g-1 wet wt; Zn =50 µg g-1 wet wtfor human consumption. These findings indicate that while mussels may be better biological indicators of heavy metal pollution in sediments than oysters,the latter may provide copper and zinc contamination.Further research is needed to determine the most appropriate biological indicators of heavy metal and other pollutants in the local marine environment and to develop protocols for their use.El Golfo de Paria está rodeado por Trinidad y Venezuela y es una fuente significativa de peces y moluscos para el consumo humano.Se extrajo muestras de ostras (Crassostrea rhizophorae y C.virginica ,mejillones (Perna viridis y sedimentos de cuatro sitios de Trinidad y tres de Venezuela en el golfo,así como muestras de tres localidades de la costa norte de Venezuela.El tejido comestible homogenizado de 12 moluscos de cada localidad fue usado para la extracción de metales pesados.El cadmio, cromo,cobre,plomo,níquel y zinc fueron analizados por espectroscopía de absorción atómica a la llama y el mercurio fue determinado por vapor al frío.Las ostras del Golfo de Paria presentaron concentraciones significativamente más altas de cadmio,cobre,níquel y zinc que las de la costa norte de Venezuela;pero esa diferencia no fue aparente en los mejillones.El mercurio en los sedimentos en todos los sitios y también el cadmio,cobre,níquel,plomo y zinc de varios sitios excedieron los niveles permisibles de las normas canadienses y estadounidenses.Los valores de cadmio, mercurio y zinc en los sedimentos se correlacionaron significativamente con los de los mejillones,pero no con los de las ostras.En las ostras los valores de cobre y zinc en varios sitios en el Golfo de Paria excedieron los límites máximos permitidos para el consumo humano.Los mejillones pueden ser mejores indicadores de contaminación de metales pesados en sedimentos,pero las ostras pueden indicar mejor la contaminaci

  2. Cheating the Locals: Invasive Mussels Steal and Benefit from the Cooling Effect of Indigenous Mussels.

    Directory of Open Access Journals (Sweden)

    Justin A Lathlean

    Full Text Available The indigenous South African mussel Perna perna gapes during periods of aerial exposure to maintain aerobic respiration. This behaviour has no effect on the body temperatures of isolated individuals, but when surrounded by conspecifics, beneficial cooling effects of gaping emerge. It is uncertain, however, whether the presence of the invasive mussel Mytilus galloprovincialis limits the ability of P. perna for collective thermoregulation. We investigated whether varying densities of P. perna and M. galloprovincialis influences the thermal properties of both natural and artificial mussel beds during periods of emersion. Using infrared thermography, body temperatures of P. perna within mixed artificial beds were shown to increase faster and reach higher temperatures than individuals in conspecific beds, indicating that the presence of M. galloprovincialis limits the group cooling effects of gaping. In contrast, body temperatures of M. galloprovincialis within mixed artificial mussel beds increased slower and exhibited lower temperatures than for individuals in beds comprised entirely of M. galloprovincialis. Interestingly, differences in bed temperatures and heating rates were largely dependent on the size of mussels, with beds comprised of larger individuals experiencing less thermal stress irrespective of species composition. The small-scale patterns of thermal stress detected within manipulated beds were not observed within naturally occurring mixed mussel beds. We propose that small-scale differences in topography, size-structure, mussel bed size and the presence of organisms encrusting the mussel shells mask the effects of gaping behaviour within natural mussel beds. Nevertheless, the results from our manipulative experiment indicate that the invasive species M. galloprovincialis steals thermal properties as well as resources from the indigenous mussel P. perna. This may have significant implications for predicting how the co-existence of

    Full Text Available Attempts to predict the response of species to long-term environmental change are generally based on extrapolations from laboratory experiments that inevitably simplify the complex interacting effects that occur in the field. We recorded heart rates of two genetic lineages of the brown mussel Perna perna over a full tidal cycle in-situ at two different sites in order to evaluate the cardiac responses of the two genetic lineages present on the South African coast to temperature and the immersion/emersion cycle. "Robomussel" temperature loggers were used to monitor thermal conditions at the two sites over one year. Comparison with live animals showed that robomussels provided a good estimate of mussel body temperatures. A significant difference in estimated body temperatures was observed between the sites and the results showed that, under natural conditions, temperatures regularly approach or exceed the thermal limits of P. perna identified in the laboratory. The two P. perna lineages showed similar tidal and diel patterns of heart rate, with higher cardiac activity during daytime immersion and minimal values during daytime emersion. Comparison of the heart rates measured in the field with data previously measured in the laboratory indicates that laboratory results seriously underestimate heart rate activity, by as much as 75%, especially during immersion. Unexpectedly, field estimates of body temperatures indicated an ability to tolerate temperatures considered lethal on the basis of laboratory measurements. This suggests that the interaction of abiotic conditions in the field does not necessarily raise vulnerability to high temperatures.

    Full Text Available The orange disease is considered the main parasitosis in Perna perna mussel. It is caused by a complex life cycle bucephalid, involving three hosts, among them mollusks and fishes. With the aim of contributing to the knowledge of orange disease in mussel culture, the parasite life cycle was investigated. Experimental studies and monthly samples in the study area allowed the identification and characterization of the Bucephalus margaritae life cycle. Larvae and adults of B. margaritae were fixed in 5% formaldehyde, stained with Gomori’s trichrome, clarified in creosote and mounted in Canada balsam. The cercariae are found in the first intermediate host P. perna inside the sporocysts, which have the form of orange and ramified filaments. The metacercariae encysts in the gills and gill cavity of the second intermediate host, the blenniid Hypleurochilus fissicornis. The definitive host Menticirrhus americanus is infected ingesting blenniids parasitized with metacercariae. The high parasitological indexes of B. margaritae suggests that M. americanus and H. fissicornis act as the main definitive and intermediate hosts, respectively, in the trematode life cycle. The blenniid H. fissicornis is a new intermediate host to the species.A bucefalose é considerada a principal parasitose do mexilhão Perna perna.

  4. Challenges associated with pre-border management of biofouling on oil rigs.

    Hopkins, Grant A; Forrest, Barrie M

    2010-11-01

    The potential for oil rigs to transport diverse, reef-like communities around the globe makes them high risk vectors for the inadvertent spread of non-indigenous species (NIS). This paper describes two case studies where a suite of pre-border management approaches was applied to semi-submersible drilling rigs. In the first case study, a drilling rig was defouled in-water prior to departure from New Zealand to Australia. Risk mitigation measures were successful in reducing biosecurity risks to the recipient region, but they resulted in the unintentional introduction of the non-indigenous brown mussel (Perna perna) to New Zealand when the rig was defouled in-water by divers. In the second case study, lessons learned from this high-profile incursion resulted in a more structured approach to pre-border management, and this serves as a useful template for future rig transfers.

    Full Text Available In 1980 and 1981 more than 50 pairs of kelp gulls Lams dominicanus, 70 of Cape cormorants Phalacrocorax capensis and 20 of whitebreasted cormorants P. carbo nested in the Tsitsikamma Coastal National Park. Kelp gulls were breeding in the Park in the mid 1960's but no records could be found of breeding by Cape cormorants prior to 1980. The earliest record for nesting by whitebreasted cormorants was 1971 and the population apparently increased in the late 1970's. Small numbers of African black oystercatchers Haematopus moquini nested in the park in 1980 and 1981. Brown mussels Perna perna and limpets Patella spp. dominated their hardshelled diet. Whereas oystercatchers at St Croix Island fed mainly on organisms from the mid intertidal region, those at Tsitsikamma appear to have favoured molluscs from the lower tidal range.

  6. Trophic transference of microplastics under a low exposure scenario: Insights on the likelihood of particle cascading along marine food-webs.

    Microplastics are emergent pollutants in marine environments, whose risks along food-web still need to be understood. Within this knowledge gap, MPs transference and persistence along trophic levels are key processes. We assessed the potential occurrence of these processes considering a less extreme scenario of exposure than used previously, with microplastics present only in the hemolymph of prey (the mussel Perna perna) and absent in the gut cavity. Predators were the crab Callinectes ornatus and the puffer fish Spheoeroides greeleyi. Transference of microplastics occurred from prey to predators but without evidences of particle persistence in their tissues after 10days of exposure. This suggests a reduced likelihood of trophic cascading of particles and, consequently, a reduced risk of direct impacts of microplastics on higher trophic levels. However, the contact with microplastics along food-webs is still concerning, modulated by the concentration of particles in prey and predators' depuration capacity and rate. Copyright © 2017.

    Marine environment contamination by natural radionuclides (uranium and 238 U daughters) is evaluated using marine -fauna and flora elements concentrating fission - and radioactivated products released by nuclear facilities. Total alpha and beta radiometry is done in the the biota to determine the radionuclide concentration. Uranium, 226 Ra and 210 PO assay is done to estimate their contribution to natural radioactivity in the chosen biological indicators. Several analytical techniques required by each radionuclide are used. Potassium assay is done to evaluate the contribution of 40 K to the natural radioactivity, and calcium assay to determine Ra/Ca and U/Ca ratios in the samples. For total alpha radiometry in algae the higher average value is detected in Phaeophyta (84.1 pCi/kg fresh weight); maximum concentration in animals is registered in Bunodosoma caissarum (43.1 pCi/kg fresh weight). For algae, the higher average total beta radiometry detected is in Chlorophyta (6.9 nCi/kg fresh weight); the maximum value found in animals refers to Thais Haemastoma (7.54 nCi/kg fresh weight). Potassium higher average ratio for algae occurs in Chlorophyta (12.77% ashes); for animals, the maximum value is found in Bunodosoma caissarum (13.80% ashes). The uranium concentration factor is maximum in Perna perna bissus (684) while the minimum is registered in Thais haemastoma and Sargassum vulgare (44). The 226 Ra concentration factor is maximum in Sargassum vulgare (2143) and minimum in Bunodosoma caissarum (32). Maximum average ratio for 210 PO in algae occurs in Phaephyta (11.5 pCi/g dry weight) and the maximum concentration for animals in Perna perna (31.5 pCi/g dry weight). The techniques employed proved to be efficient for the objectives aimed at. (Author) [pt

  12. The role of gaping behaviour in habitat partitioning between coexisting intertidal mussels

    Full Text Available Abstract Background Environmental heterogeneity plays a major role in invasion and coexistence dynamics. Habitat segregation between introduced species and their native competitors is usually described in terms of different physiological and behavioural abilities. However little attention has been paid to the effects of behaviour in habitat partitioning among invertebrates, partially because their behavioural repertoires, especially marine benthic taxa, are extremely limited. This study investigates the effect of gaping behaviour on habitat segregation of the two dominant mussel species living in South Africa, the invasive Mytilus galloprovincialis and the indigenous Perna perna. These two species show partial habitat segregation on the south coast of South Africa, the lower and upper areas of the mussel zone are dominated by P. perna and M. galloprovincialis respectively, with overlap in the middle zone. During emergence, intertidal mussels will either keep the valves closed, minimizing water loss and undergoing anaerobic metabolism, or will periodically open the valves maintaining a more efficient aerobic metabolism but increasing the risk of desiccation. Results Our results show that, when air exposed, the two species adopt clearly different behaviours. M. galloprovincialis keeps the shell valves closed, while P. perna periodically gapes. Gaping behaviour increased water loss in the indigenous species, and consequently the risk of desiccation. The indigenous species expressed significantly higher levels of stress protein (Hsp70 than M. galloprovincialis under field conditions and suffered significantly higher mortality rates when exposed to air in the laboratory. In general, no intra-specific differences were observed in relation to intertidal height. The absence of gaping minimises water loss but exposes the invasive species to other stresses, probably related to anoxic respiration. Conclusions Gaping affects tolerance to desiccation, thus

    This work aimed to investigate metal bioaccumulation by mussels (Perna perna) and Lion's Scallop (Nodipecten nodosus) farmed in tropical bays, in order to estimate spatial and temporal variation in the exposure to these elements, as well as human health risk. The concentration of each measured element was considered for this evaluation, using maximum residue level (MRL) in foods established by the Brazilian (ANVISA), American (USFDA) and European Communities (EC) legislations. Values for estimated daily ingestion (EDI) were determined for metals intake through mussel and scallop consumption. These estimates were compared with the reference value of (PTDI) proposed by World Health Organization (WHO). Trace elements concentration was measured on ninety mussels P. perna (tissue) and ninety Lion's Scallop N. nodosus (muscle and gonad) reared in four different tropical areas of the Southeast Brazilian coast, between 2009 and 2010. Zinc (Zn), Iron (Fe), Copper (Cu), Manganese (Mn), Chrome (Cr), Nickel (Ni), Cadmium (Cd) and Lead (Pb) concentrations were measured by flame atomic absorption spectrometry after acid mineralization. Cd and Mn were more efficiently bioaccumulated by scallops than mussels and the opposite was found for Fe, Cu and Ni. Guanabara Bay and Sepetiba Bay were considered the most impacted between ecosystems studied. Higher Cd values in Arraial do Cabo in the other sites studied were associated with upwelling that occurs in the region. Consumption of both species cannot be considered safe, because the Cu and Cr concentrations, in accordance with the limits established by the Brazilian Agency (ANVISA). On the other hand, any EDI value exceeded the corresponding value of the PTDI, proposed by World Health Organization (WHO). Copyright © 2015 Elsevier GmbH. All rights reserved.

    Punshon-Smith, Samuel; Smith, Scott

    2018-02-01

    This article studies the Cauchy problem for the Boltzmann equation with stochastic kinetic transport. Under a cut-off assumption on the collision kernel and a coloring hypothesis for the noise coefficients, we prove the global existence of renormalized (in the sense of DiPerna/Lions) martingale solutions to the Boltzmann equation for large initial data with finite mass, energy, and entropy. Our analysis includes a detailed study of weak martingale solutions to a class of linear stochastic kinetic equations. This study includes a criterion for renormalization, the weak closedness of the solution set, and tightness of velocity averages in {{L}1}.

    2004-09-01

    A severe outbreak of Paralytic Shellfish Poisoning (PSP) occurred in Manzanillo and Guayacán, northwestern coast of Margarita Island, Venezuela, between August and October 1991. A bloom of dinoflagellates including Prorocentrum gracile, Gymnodinium catenatum and Alexandrium tamarense seemed to be responsible for this outbreak. Levels of PSP toxins in mussels (Perna perna) exceeded the international safety limit of saxitoxin, 80 microg STX/100 microg meat. PSP toxin values varied between 2548 and 115 microg STX/100 g meat in Manzanillo, and between 1422 and 86 microg STX/100 g meat in Guayacán. At both locations, the highest levels were detected in August, when 24 patients exhibited typical symptoms of PSP toxicity after consuming cooked mussels (16 required hospitalization). A high pressure liquid chromatographic (HPLC) procedure was recently used on the 1991 samples. The major toxin detected in samples of both locations was decarbamoyl saxitoxin (dcSTX), but low concentrations of saxitoxin were also found in Manzanillo samples. Gonyautoxins GTX1, GTX2 and GTX3 were detected only at Guayacán, while in both locations, decarbamoylgonyatouxin (dcGTX2,3) toxins were detected. These findings represent the first time that causative toxins of PSP in Venezuela have been chemically identified, and confirm the presence of dcSTX and dcGTX in mussels from the Caribbean Sea. The presence of dcSTX and dcGTX in shellfish is indicative that Gymnodinium catenatum was a causative organism for outbreak of PSP.

  11. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

    Full Text Available Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and Pacific oceans and in the Caribbean and Mediterranean seas. Brazilian sponges remain understudied concerning antifouling activities. Only two scientific articles reported this activity in sponges of Brazil. The objective of this study was to test crude extracts of twelve species of sponges from Brazil against the attachment of the mussel Perna perna through laboratorial assays, and highlight promising species for future studies. The species Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra, and Tethya maza were frozen and freeze-dried before extraction with acetone or dichloromethane. The crude extract of four species significantly inhibited the attachment of byssus: Tethya rubra (p = 0.0009, Tethya maza (p = 0.0039, Petromica citrina (p = 0.0277, and Hymeniacidon heliophila (p = 0.00003. These species, specially, should be the target of future studies to detail the substances involved in the ability antifouling well as to define its amplitude of action.

  12. A critical examination of the possible application of zinc stable isotope ratios in bivalve mollusks and suspended particulate matter to trace zinc pollution in a tropical estuary.

    The application of zinc (Zn) isotopes in bivalve tissues to identify zinc sources in estuaries was critically assessed. We determined the zinc isotope composition of mollusks (Crassostrea brasiliana and Perna perna) and suspended particulate matter (SPM) in a tropical estuary (Sepetiba Bay, Brazil) historically impacted by metallurgical activities. The zinc isotope systematics of the SPM was in line with mixing of zinc derived from fluvial material and from metallurgical activities. In contrast, source mixing alone cannot account for the isotope ratios observed in the bivalves, which are significantly lighter in the contaminated metallurgical zone (δ 66 Zn JMC  = +0.49 ± 0.06‰, 2σ, n = 3) compared to sampling locations outside (δ 66 Zn JMC  = +0.83 ± 0.10‰, 2σ, n = 22). This observation suggests that additional factors such as speciation, bioavailability and bioaccumulation pathways (via solution or particulate matter) influence the zinc isotope composition of bivalves.

    Biofouling studies in the coastal waters of Kalpakkam were carried out with an aim to delineate the present seasonal succession and fouling potential of macrofoulants, the dominant species and their breeding period. Three series (weekly, monthly and cumulative at 30 d interval observations) of teak wood panels were exposed to coastal waters from a jetty. A marked variation was observed in the colonization of the biofoulers on the weekly panels during the present study. The highest and lowest numbers of organisms observed were 136 and 1 per sq. cm respectively. Dominance of barnacles (12.4 - 99 %) on weekly panels was found throughout the study period. A climax community of green mussels (Perna viridis) was observed in the cumulative observations. Biofouling biomass of weekly panels varied between 1 and 11 g. (100 cm) -2 , however, a steep increase in biomass was observed in 28 d (77 g. (100 cm) -2 ), 56 d (97 g. (100 cm) -2 ), 112 d (185 g. (100 cm) -2 ) and 150 d (648 g. (100 cm) -2 ) old panels. In the present study, the biomass values found to be significantly higher than those of the earlier reported values (33 and 52 g. (100 cm) -2 in 43 d and 128 d exposure respectively). Interestingly, a visible shift in the peak settlement period of green mussels (Perna viridis) was observed in the present investigation, as compared to the earlier study. (author)

    Three kinds of marine bivalves (wild Saccostrea cucullata, aquacultured Perna viridis and aquacultured Pinctada martens), collected from Daya Bay, the South China Sea, were used to investigate the bio-accumulation of radioruthenium in the glass aquarium with natural seawater (pH 8.20, 35 per mille salinity, filtered by 0.45 μm) at ambient temperature under laboratory feeding conditions. The experimental results show that the stead-state of biology concentration factor (BCF, ml/g) of radioruthenium was approached around 6 days for most species of bivalves. The values of BCF in shells are the highest in organs all the three bivalves. The orders of BCF values (ml x g -1 ) are as: Perna viridis (33.2) < Saccostrea cucullata (47.0) < Pinctada martensi (208.4) for shells and Saccostrea cucullata (1.5) < Pinctada martensi (2.2) ∼ Perma viridis (2.4) for soft tissues, respectively, after exposed for 14 days. The rate constants of uptake and elimination of radioruthenium on marine bivalves were also discussed by first-order kinetics model. The Pinctada martensi may be applicable to be an indictor for monitoring radioruthenium among the three bivalves. (author)

    Polonium-210 ({sup 210}Po) radioactive concentrations were determined in human semen fluid of vasectomized non-smoker volunteers. The {sup 210}Po levels ranged from 0.10 to 0.39 mBq g{sup -1} (mean: 0.23 {+-} 0.08 mBq g{sup -1}). This value decreased to 0.10 {+-} 0.02 mBq g{sup -1} (range from 0.07 to 0.13 mBq g{sup -1}) after two weeks of a controlled diet, excluding fish and seafood. Then, volunteers ate during a single meal 200 g of the cooked mussel Perna perna L., and {sup 210}Po levels were determined again, during ten days, in semen fluid samples collected every morning. Volunteers continued with the controlled diet and maintained sexual abstinence through the period of the experiment. A 300% increase of {sup 210}Po level was observed the day following mussel consumption, with a later reduction, such that the level returned to near baseline by day 4.

  17. Non-native marine invertebrates are more tolerant towards environmental stress than taxonomically related native species: results from a globally replicated study.

    To predict the risk associated with future introductions, ecologists seek to identify traits that determine the invasiveness of species. Among numerous designated characteristics, tolerance towards environmental stress is one of the most favored. However, there is little empirical support for the assumption that non-native species generally cope better with temporarily unfavorable conditions than native species. To test this concept, we ran five pairwise comparisons between native and non-native marine invertebrates at temperate, subtropical, and tropical sites. We included (natives named first) six bivalves: Brachidontes exustus and Perna viridis, P. perna and Isognomon bicolor, Saccostrea glomerata and Crassostrea gigas, two ascidians: Diplosoma listerianum and Didemnum vexillum as well as two crustaceans: Gammarus zaddachi and G. tigrinus. We simulated acute fluctuations in salinity, oxygen concentration, and temperature, while we measured respiration and survival rates. Under stressful conditions, non-native species consistently showed less pronounced deviations from their normal respiratory performance than their native counterparts. We suggest that this indicates that they have a wider tolerance range. Furthermore, they also revealed higher survival rates under stress. Thus, stress tolerance seems to be a property of successful invaders and could therefore be a useful criterion for screening profiles and risk assessment protocols. Copyright © 2011 Elsevier Inc.

    Food from marine origin is considered as one of the sources that most contributes to internal radioactive contamination in humans by polonium-210 ({sup 210}Po). This work intended to check whether a single ingestion of the mussel Perna perna should result in a detectable increase of radioactive contamination in the consumer. The mussel was bought at a fish market localized in the city of Niteroi, RJ, Brazil. It was cooked as usually, and its content in {sup 210}Po determined after acid mineralization, spontaneous electrodeposition on stainless steel disks and alpha counting. Non-smoking volunteers maintained for two weeks a normal diet, but completely avoiding fish and seafood. Then, they ate 200 g of cooked mussel, and collected total faeces and urine every day during ten days. {sup 210}Po level in faeces samples showed a 900% increase at the first day after ingestion, and reached normal levels after 3-4 days. In urine samples, the increase of {sup 210}Po was much lower (50%) and reached a maximum at the fifth day. Such data showed a short time permanence of {sup 210}Po in the intestine. Most of ingested {sup 210}Po ({approx}91%) was eliminated in up to 5 days through faeces. A small amount was absorbed ({approx}5-10%), part of it being eliminated in urine, and the remaining contaminated the human body. (author)

  20. L^1 singular limit for relaxation and viscosity approximations of extended traffic flow models

    Christian Klingenberg

    2003-03-01

    Full Text Available This paper considers the Cauchy problem for an extended traffic flow model with $L^1$-bounded initial data. A solution of the corresponding equilibrium equation with $L^1$-bounded initial data is given by the limit of solutions of viscous approximations of the original system as the dissipation parameter $epsilon$ tends to zero more slowly than the response time $au$. The proof of convergence is obtained by applying the Young measure to solutions introduced by DiPerna and, based on the estimate $$ | ho(t,x| leq sqrt {| ho_0(x|_1/(ct} $$ derived from one of Lax's results and Diller's idea, the limit function $ ho(t,x$ is shown to be a $L^1$-entropy week solution. A direct byproduct is that we can get the existence of $L^1$-entropy solutions for the Cauchy problem of the scalar conservation law with $L^1$-bounded initial data without any restriction on the growth exponent of the flux function provided that the flux function is strictly convex. Our result shows that, unlike the weak solutions of the incompressible fluid flow equations studied by DiPerna and Majda in [6], for convex scalar conservation laws with $L^1$-bounded initial data, the concentration phenomenon will never occur in its global entropy solutions.

    The guidelines for the Environmental Risk Assessment (ERA) of pharmaceuticals and personal care products (PPCP) recommend the use of standard ecotoxicity assays and the assessment of endpoints at the individual level to evaluate potential effects of PPCP on biota. However, effects at the sub-individual level can also affect the ecological fitness of marine organisms chronically exposed to PPCP. The aim of the current study was to evaluate the environmental risk of two PPCP in marine sediments: triclosan (TCS) and ibuprofen (IBU), using sub-individual and developmental endpoints. The environmental levels of TCS and IBU were quantified in marine sediments from the vicinities of the Santos submarine sewage outfall (Santos Bay, São Paulo, Brazil) at 15.14 and 49.0 ng g -1 , respectively. A battery (n = 3) of chronic bioassays (embryo-larval development) with a sea urchin (Lytechinus variegatus) and a bivalve (Perna perna) were performed using two exposure conditions: sediment-water interface and elutriates. Moreover, physiological stress through the Neutral Red Retention Time Assay (NRRT) was assessed in the estuarine bivalve Mytella charruana exposed to TCS and IBU spiked sediments. These compounds affected the development of L. variegatus and P. perna (75 ng g -1 for TCS and 15 ng g -1 for IBU), and caused a significant decrease in M. charruana lysosomal membrane stability at environmentally relevant concentrations (0.08 ng g -1 for TCS and 0.15 ng g -1 for IBU). Chemical and ecotoxicological data were integrated and the risk quotient estimated for TCS and IBU were higher than 1.0, indicating a high environmental risk of these compounds in sediments. These are the first data of sediment risk assessment of pharmaceuticals and personal care products of Latin America. In addition, the results suggest that the ERA based only on individual-level and standard toxicity tests may overlook other biological effects that can affect the health of marine organisms

  9. The Acoustic Limit for the Boltzmann Equation

    Science.gov (United States)

    Bardos, Claude; Golse, François; Levermore, C. David

    The acoustic equations are the linearization of the compressible Euler equations about a spatially homogeneous fluid state. We first derive them directly from the Boltzmann equation as the formal limit of moment equations for an appropriately scaled family of Boltzmann solutions. We then establish this limit for the Boltzmann equation considered over a periodic spatial domain for bounded collision kernels. Appropriately scaled families of DiPerna-Lions renormalized solutions are shown to have fluctuations that converge entropically (and hence strongly in L1) to a unique limit governed by a solution of the acoustic equations for all time, provided that its initial fluctuations converge entropically to an appropriate limit associated to any given L2 initial data of the acoustic equations. The associated local conservation laws are recovered in the limit.

  13. Conservation laws with coinciding smooth solutions but different conserved variables

    2018-04-01

    Consider two hyperbolic systems of conservation laws in one space dimension with the same eigenvalues and (right) eigenvectors. We prove that solutions to Cauchy problems with the same initial data differ at third order in the total variation of the initial datum. As a first application, relying on the classical Glimm-Lax result (Glimm and Lax in Decay of solutions of systems of nonlinear hyperbolic conservation laws. Memoirs of the American Mathematical Society, No. 101. American Mathematical Society, Providence, 1970), we obtain estimates improving those in Saint-Raymond (Arch Ration Mech Anal 155(3):171-199, 2000) on the distance between solutions to the isentropic and non-isentropic inviscid compressible Euler equations, under general equations of state. Further applications are to the general scalar case, where rather precise estimates are obtained, to an approximation by Di Perna of the p-system and to a traffic model.

    Microplastic pollution (particles microplastic pollution on Santos estuary, the most urbanized area of the coast of São Paulo State, Brazil. A simple and rapid assessment showed that 75% of sampled mussels had ingested microplastics, an issue of human and environmental concern. All sampling points had contaminated mussels and this contamination had no clear pattern of distribution along the estuary. This was the first time that microplastic bioavailability was assessed in nature for the southern hemisphere and that wild P. perna was found contaminated with this pollutant. This is an important issue that should be better assessed due to an increase in seafood consumption and culture in Brazil and worldwide. Copyright © 2016 Elsevier Ltd. All rights reserved.

  17. Boundary-layer interactions in the plane-parallel incompressible flows

    International Nuclear Information System (INIS)

    Nguyen, Toan T; Sueur, Franck

    2012-01-01

    We study the inviscid limit problem of incompressible flows in the presence of both impermeable regular boundaries and a hypersurface transversal to the boundary across which the inviscid flow has a discontinuity jump. In the former case, boundary layers have been introduced by Prandtl as correctors near the boundary between the inviscid and viscous flows. In the latter case, the viscosity smoothes out the discontinuity jump by creating a transition layer which has the same amplitude and thickness as the Prandtl layer. In the neighbourhood of the intersection of the impermeable boundary and of the hypersurface, interactions between the boundary and the transition layers must then be considered. In this paper, we initiate a mathematical study of this interaction and carry out a strong convergence in the inviscid limit for the case of the plane-parallel flows introduced by Di Perna and Majda (1987 Commun. Math. Phys. 108 667–89). (paper)

    Full Text Available Determinou-se o efeito do regime alimentar para ganho compensatório sobre a composição regional e tecidual da carcaça de cordeiros terminados em confinamento. Foram utilizados 40 ovinos Santa Inês, machos, com média de 17±1,7kg de peso vivo (PV e 100 dias de idade. Ao final do período de confinamento, os cordeiros foram abatidos, e a meia carcaça esquerda foi seccionada em cinco cortes comerciais primários: pescoço, paleta, costilhar, lombo e perna. A perna foi dissecada em músculos, ossos e gorduras, e, em seguida, teve seu índice de musculosidade determinado. Foi mensurada a hipertrofia muscular por meio da média do diâmetro das fibras musculares. O peso (g da meia carcaça esquerda, do pescoço, da paleta, do costilhar, do lombo e da perna diminuiu linearmente, à medida que aumentou o nível de restrição prévia, de 0% até 60%, variando, respectivamente, de 11497,4 a 8888,5; de 1453,8 a 1211,4; de 1955,4 a 1560,9; de 3420,0 a 2604,6; de 1669,4 a 1161,6 e de 2998,8 a 2350,0.

    This investigation was carried out as part of Thailand's participation in the global 'Mussel Watch' program. The levels of Cd, Cr, Cu, Pb, and Zn in the green mussel, Perna viridis, oyster, Crassostrea commercialis, and the cockle, Anadara granosa, were studied from July 1982 to November 1982. Comparison was made with the previous study in August 1981 which also included the short necked clam, Paphia undulata and moon scallop, Amusium pleuronectes. It was found that the metal levels were sufficiently low that the molluscs could be consumed without any danger to health. The salinity of the water appeared to influence the uptake as higher levels of metals were found during the flood season when salinity was lower.

    This paper has identified, for the first time in a member of the Rhodophyta, a vacuolar organelle containing enzymes that are involved in the mevalonate pathway-an important step in red algal isoprenoid biosynthesis. These organelles were named mevalonosomes (Mev) and were found in the cortical cells (CC) of Plocamium brasiliense, a marine macroalgae that synthesizes several halogenated monoterpenes. P. brasiliense specimens were submitted to a cytochemical analysis of the activity of the 3-hydroxy-3-methylglutaryl-CoA synthase (HMGS). Using transmission electron microscopy (TEM), we confirmed the presence of HMGS activity within the Mev. Because HMGS is necessary for the biosynthesis of halogenated monoterpenes, we isolated a hexanic fraction (HF) rich in halogenated monoterpenes from P. brasiliense that contained a pentachlorinated monoterpene as a major metabolite. Because terpenes are often related to chemical defense, the antifouling (AF) activity of pentachlorinated monoterpene was tested. We found that the settlement of the mussel Perna perna was reduced by HF treatment (2.25 times less than control; 40% and 90% of fouled surface, respectively; P = 0.001; F9,9 = 1.13). The HF (at 10 μg · mL(-1) ) also inhibited three species of fouling microalgae (Chlorarachnion reptans, Cylindrotheca cloisterium, and Exanthemachrysis gayraliae), while at a higher concentration (50 μg · mL(-1) ), it inhibited the bacteria Halomonas marina, Polaribacter irgensii, Pseudoalteromonas elyakovii, Shewanella putrefaciens, and Vibrio aestuarianus. The AF activity of P. brasiliense halogenated monoterpenes and the localization of HMGS activity inside Mev suggest that this cellular structure found in CC may play a role in thallus protection against biofouling. © 2015 Phycological Society of America.

    Full Text Available Avaliou-se o efeito de dietas contendo diferentes teores de borra de soja sobre o consumo de nutrientes, o ganho de peso, as características de carcaça e os componentes do peso vivo de cordeiros terminados em confinamento. Foram utilizados 25 cordeiros, machos, castrados, da raça Texel, distribuídos aleatoriamente em cinco tratamentos compostos por proporções de 0%, 2,89%, 5,77%, 8,65% ou 11,55% de borra de soja na matéria seca das dietas. Houve redução linear do consumo de nutrientes, com exceção do consumo de extrato etéreo, que aumentou linearmente. O peso vivo ao abate, o ganho de peso diário, os pesos e rendimentos de carcaça quente e fria, e os pesos de perna e de costilhar diminuíram linearmente, ao passo que as proporções de rúmen e do trato gastrintestinal, com conteúdo, bem como o conteúdo gastrointestinal, aumentaram linearmente com o aumento dos níveis de borra de soja nas dietas. A proporção de perna foi influenciada de forma quadrática. O aumento da participação de borra de soja na dieta de cordeiros em sistema de confinamento leva à diminuição do desempenho produtivo dos animais. Contudo, o lucro diário obtido por animal não é influenciado, podendo-se inferir que a inclusão de borra de soja até o nível de 11,55% da matéria seca total da dieta é uma alternativa viável para a terminação de cordeiros em confinamento.

    High correlation between mercury (Hg) and selenium (Se) concentrations in fish organs is well known. In the present study, 58 fish samples of five fish species most commonly consumed by the Cubatao city population, Sao Paulo State, Brazil were analyzed. The Cubatao Estuary, located in southeastern Sao Paulo State, is an economically important area suffering severe environmental water quality problems due to industrial wastes, domestic sewage and solid residues. The waters of the bay suffer the impact of the immense industrial complex of Cubatao. In this study, Hg concentration in muscle, liver and kidney tissues and Se concentration in liver tissue from three predatory fish species: Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de Moca) and Micropogonias furnieri (Corvina) and two planctivorous species: Mugil liza (Tainha) and Sardella braziliensis (Sardinha) were determined. Mercury determination was performed using Cold Vapour Atomic Absorption Spectrometry (CV AAS) and selenium by Instrumental Neutron Activation Analysis (INAA). The muscle-Hg concentration variation (wet weight) was: (8 to 40 mug kg{sup -1}) - Sardinha; (12 to 62 mug kg{sup -1}) - Pescada; (3 to 23 mug kg{sup -1}) - Tainha; (43 to 184 mug kg{sup -1}) - Perna de Moca and (41 to 348 mug kg{sup -1}) - Corvina. The general concentration ranges of the analyzed elements in all species studied were (dry weight): muscle-Hg (13 to 1512 mug kg{sup -1}); liver-Hg (21 to 1804 mug kg{sup -1}); kidney-Hg 47 to 9912 mug kg{sup -1}) and liver-Se (2.10 to 43.00 mg kg{sup -1}). Se concentrations were higher than those of Hg in the liver. (author)

    This study aimed to provide the first biomonitoring integrating biomarkers and bioaccumulation data in São Paulo coast, Brazil and, for this purpose, a battery of biomarkers of defense mechanisms was analyzed and linked to contaminants' body burden in a weigh-of-evidence approach. The brown mussel Perna perna was selected to be transplanted from a farming area (Caraguatatuba) to four possibly polluted sites: Engenho D'Água, DTCS (Dutos e Terminais do Centro-Oeste de São Paulo) oil terminal (Sao Sebastiao zone), Palmas Island, and Itaipu (It; Santos Bay zone). After 3 months of exposure in each season, mussels were recollected and the cytochrome P4501A (CYP1A)- and CYP3A-like activities, glutathione-S-transferase and antioxidants enzymes (catalase, glutathione peroxidase, and glutathione reductase) were analyzed in gills. The concentrations of polycyclic aromatic hydrocarbons, linear alkylbenzenes, and nonessential metals (Cr, Cd, Pb, and Hg) in whole tissue were also analyzed and data were linked to biomarkers' responses by multivariate analysis (principal component analysis-factor analysis). A representation of estimated factor scores was performed to confirm the factor descriptions and to characterize the studied stations. Biomarkers exhibited most significant alterations all year long in mussels transplanted to It, located at Santos Bay zone, where bioaccumulation of organic and inorganic compounds was detected. This integrated approach using transplanted mussels showed satisfactory results, pointing out differences between sites, seasons, and critical areas, which could be related to land-based contaminants' sources. The influence of natural factors and other contaminants (e.g., pharmaceuticals) on biomarkers' responses are also discussed. Copyright © 2010 Wiley Periodicals, Inc.

The muscle-Hg concentration variation (wet weight) was: (8 to 40 μg kg -1 ) - Sardinha; (12 to 62 μg kg -1 ) - Pescada; (3 to 23 μg kg -1 ) - Tainha; (43 to 184 μg kg -1 ) - Perna de Moca and (41 to 348 μg kg -1 ) - Corvina. The general concentration ranges of the analyzed elements in all species studied were (dry weight): muscle-Hg (13 to 1512 μg kg -1 ); liver-Hg (21 to 1804 μg kg -1 ); kidney-Hg 47 to 9912 μg kg -1 ) and liver-Se (2.10 to 43.00 mg kg -1 ). Se concentrations were higher than those of Hg in the liver. (author)

    Full Text Available In the literature it has been extensively mentioned that crab spiders (Araneae: Thomisidae prey on floral visitors of several plant species. Here we present observations of Croton selowii Baill. (Euphorbiaceae, a monoecious species harboring individuals of crab spiders in an area of coastal vegetation of Pernambuco state, Brazil. The species is visited by several invertebrate orders, and some of them were preyed upon by the spiders, mainly Diptera species. The spiders rubbed the forelimbs within the flowers, which may constitute a strategy to camouflage these structures. Croton selowii seems to represent a suitable foraging site for the spiders, because it has a generalist pollination system (thus being visited by a wide range of invertebrate species and blooms in a period of low flower resource availability in the area.Na literatura tem sido amplamente registrado que aranhas Thomisidae predam visitantes florais de várias espécies de planta. Neste estudo nós apresentamos observações de Croton selowii Baill. (Euphorbiaceae, uma espécie monóica, abrigando aranhas Thomisidae em uma área de restinga de Pernambuco, Brasil. A espécie é visitada por invertebrados de várias ordens e vários deles são predados pelas aranhas, principalmente espécies de Diptera. As aranhas apresentaram um comportamento de esfregar as pernas dianteiras dentro das flores, o que pode ser interpretado como uma estratégia de camuflagem das pernas. Croton selowii parece representar um bom sítio de forrageamento para essas aranhas, pois possui um sistema de polinização generalista, sendo visitado por ampla gama de invertebrados e floresce em um período de baixa disponibilidade de flores na área.

  10. Effects of endolithic parasitism on invasive and indigenous mussels in a variable physical environment.

    Directory of Open Access Journals (Sweden)

    Gerardo Ivan Zardi

    Full Text Available Biotic stress may operate in concert with physical environmental conditions to limit or facilitate invasion processes while altering competitive interactions between invaders and native species. Here, we examine how endolithic parasitism of an invasive and an indigenous mussel species acts in synergy with abiotic conditions of the habitat. Our results show that the invasive Mytilus galloprovincialis is more infested than the native Perna perna and this difference is probably due to the greater thickness of the protective outer-layer of the shell of the indigenous species. Higher abrasion due to waves on the open coast could account for dissimilarities in degree of infestation between bays and the more wave-exposed open coast. Also micro-scale variations of light affected the level of endolithic parasitism, which was more intense at non-shaded sites. The higher levels of endolithic parasitism in Mytilus mirrored greater mortality rates attributed to parasitism in this species. Condition index, attachment strength and shell strength of both species were negatively affected by the parasites suggesting an energy trade-off between the need to repair the damaged shell and the other physiological parameters. We suggest that, because it has a lower attachment strength and a thinner shell, the invasiveness of M. galloprovincialis will be limited at sun and wave exposed locations where endolithic activity, shell scouring and risk of dislodgement are high. These results underline the crucial role of physical environment in regulating biotic stress, and how these physical-biological interactions may explain site-to-site variability of competitive balances between invasive and indigenous species.

    The present study focused on the determination of the alpha-emitter, 210 Po, in two species of marine mussels (bivalve molluscs) commonly available in the southern coastal region of India. The brown mussel, Perna indica was collected from the west coast and the green mussel, Perna viridis from the east coast. The concentration of 210 Po was related to the allometry (length of shell, wet/dry weight of shell/soft tissue) of the mussels and significant results were found. The study period focused on three seasons namely, pre-monsoon, monsoon and post-monsoon for a 1-year period (2010–2011). The results revealed higher activity levels in smaller-sized mussels compared to larger ones. Marked variation in 210 Po activity concentration was noted in the whole-body soft tissues between seasons and sampling site (p < 0.05). The dose rate assessment for mussels was performed using the ERICA Assessment tool. The chronic exposure to mussels due to 210 Po was found to be lesser than the global benchmark dose rate of 10 μGy h −1 . The effective ingestion dose to adults who intake mussels was estimated to be in the range 5.1–34.9 μSv y −1 . The measurement contributes to the furthering of knowledge of 210 Po, since no data exist in this region. - Highlights: • Polonium-210 was quantified in two species of Mytilid mussels inhabiting southern coast of India. • Polonium-210 activity showed significant variation among size classes, between seasons and sampling site. • The internal dose rate to mussels and the dose assessment to the adult population were performed

  13. Patchiness and co-existence of indigenous and invasive mussels at small spatial scales: the interaction of facilitation and competition.

    Johan Erlandsson

    Full Text Available Ecological theory predicts that two species with similar requirements will fail to show long-term co-existence in situations where shared resources are limiting, especially at spatial scales that are small relative to the size of the organisms. Two species of intertidal mussels, the indigenous Perna perna and the invasive Mytilus galloprovincialis, form mixed beds on the south coast of South Africa in a situation that has been stable for several generations of these species, even though these populations are often limited by the availability of space. We examined the spatial structure of these species where they co-exist at small spatial scales in the absence of apparent environmental heterogeneity at two sites, testing: whether conspecific aggregation of mussels can occur (using spatial Monte-Carlo tests; the degree of patchiness (using Korcak B patchiness exponent, and whether there was a relationship between percent cover and patchiness. We found that under certain circumstances there is non-random conspecific aggregation, but that in other circumstances there may be random distribution (i.e. the two species are mixed, so that spatial patterns are context-dependent. The relative cover of the species differed between sites, and within each site, the species with higher cover showed low Korcak B values (indicating low patchiness, i.e. the existence of fewer, larger patches, while the less abundant species showed the reverse, i.e. high patchiness. This relationship did not hold for either species within sites. We conclude that co-existence between these mussels is possible, even at small spatial scales because each species is an ecological engineer and, while they have been shown to compete for space, this is preceded by initial facilitation. We suggest that a patchy pattern of co-existence is possible because of a balance between direct (competitive and indirect (facilitative interactions.

A carcaça foi dividida em cinco cortes cárneos (perna, lombo, costelas, paleta e pescoço, os quais foram pesados para cálculo de seus rendimentos em relação ao peso da meia-carcaça. A perna foi dissecada em músculo, osso e gordura e os pesos desses tecidos foram expressos em peso absoluto e em porcentagem da perna. Calcularam-se as relações músculo:osso e músculo:gordura, o índice de musculosidade da perna (IMP e a área de olho-de-lombo (AOL. O aumento de 30 para 60% de concentrado na dieta elevou os rendimentos de carcaça quente e carcaça fria, assim como o rendimento biológico.

    Full Text Available The swimming behavior exhibited by specimens of L. fasciatus and O. uniformis was analyzed frame-by-frame with video observation recorded with a digital camera, attached to a stereomicroscope. Adults of O. uniformis, an aquatic insect, swim with all three pairs of legs. During the process of swimming the majority of the abdomen and rostrum remain submerged, part of the fore and hind tibiae remain above the surface, while the mid tibiae remain submerged. The mesothoracic legs, during the power-stroke stage, provide the greatest thrust while the metathoracic legs provide the least forward propulsion. The prothoracic legs, extended forward, help to direct the swimming. The semi-aquatic specie L. fasciatus shows the same swimming style as O. uniformis, that is, with movement of all the three pairs of legs; the mesothoracic legs are responsible for the main propulsion. The insect body remains on the water surface during the process of swimming, while the legs remain submerged. Both species complete a swimming cycle in 0.33 and 0.32 seconds, respectively, with an average speed of 1.38 cm/s and a maximum and minimum swimming duration time of 11.15 and 5.05 minutes, respectively, for L. fasciatus. The swimming behavior exhibited by O. uniformis and L. fasciatus corresponds to the style known as a breast strokelike maneuver. This is the first record of this kind of swimming for both species here observed and increases to seven the number of genera of Curculionidae exhibiting this behavior.O comportamento de nado exibido por indivíduos de L. fasciatus e O. uniformis foi analisado quadro a quadro através de imagens obtidas com o auxílio de uma câmera fotográfica digital com opção de vídeo, acoplada a um estereomicroscópio.

    Full Text Available Objetivou-se com este trabalho avaliar as características de desempenho e de carcaça de sete genótipos de frangos tipo caipira da linhagem Redbro. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. Os frangos foram alojados em 28 boxes, sendo 30 frangos por boxe, em galpão de alvenaria com acesso a um piquete de 45m², em quatro repetições. As características de desempenho (conversão alimentar, ganho em peso médio diário, consumo de ração médio diário foram avaliadas nos períodos: um a 28, um a 56, um a 70 e um a 84 dias de idade. O peso corporal foi avaliado aos 28, 56, 70 e 84 dias de idade. As características de carcaça (peso e rendimento de carcaça, peito e pernas foram obtidas a partir do abate de dois frangos por boxe, aos 85 dias de idade. As análises estatísticas foram realizadas utilizando-se o "proc glm" do SAS. Verificou-se que, em todos os períodos, os frangos do genótipo Colorpak apresentaram maior peso corporal, consumo de ração médio diário, ganho em peso médio diário e melhor conversão alimentar. Entretanto, os genótipos Caboclo e Gigante Negro apresentaram menores consumo de ração médio diário, ganho de peso médio diário e pior conversão alimentar. Quanto ao rendimento de cortes, observou-se que os genótipos Caboclo e Gigante Negro apresentaram os menores valores, e o Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor obtiveram os melhores rendimentos de pernas. Para o rendimento de peito, o Carijó e o Pesadão Vermelho obtiveram os maiores valores. A escolha do genótipo deve ser feita de acordo com o interesse do mercado, pois há diferenças no desempenho e no rendimento de carcaça e dos cortes.

As aves foram pesadas e distribuídas aleatoriamente em quatro lotes: Lote de pintinhos com peso inicial maior que 1 kg de peso vivo que consumiram ração tipo A; Lote de pintinhos com peso inicial menor que 1 kg de peso vivo que consumiram ração tipo A, sendo os animais identificados através de uma anilha de fio de cobre em uma das pernas; Lote de pintinhos com peso inicial maior que 1 kg de peso vivo que consumiram ração tipo B; e finalmente, Lote de pintinhos com peso inicial menor que 1 kg de peso vivo que consumiram ração tipo B, sendo os animais identificados através de uma anilha de fio de cobre em uma das pernas. A ração do tipo A foi empregado milho e concentrado protéico comercial, enquanto a ração do tipo B foi empregado milho, concentrado protéico e pé-de-cuba, sendo os dois tipos consideradas isoprotéicas e isocalóricas. Não foi verificada diferença significativa entre os tratamentos para as variáveis ganho de peso, hematócrito, número de hemácias, concentração de hemoglobina, contagem global de leucócitos e trombócitos. Entretanto, na contagem diferencial de leucócitos, houve uma menor relação heterófilo/linfócito no sangue dos animais que consumiram a ração do tipo B, indicando menor condição de estresse nestes animais. Neste estudo, a substituição de parte de milho pelo pé-de-cuba, reduziu o preço por quilograma da ração em 23,21%, representando um subproduto de interesse para o pequeno produtor de cachaça na produção de aves no sistema caipira.

Quarenta e nove cordeiros machos não-castrados da raça Texel, nascidos em duas épocas (agosto e novembro, foram mantidos em regime de pastagem e abatidos com média de idade de 129 e 164 dias, respectivamente. Previamente aos abates foi feita a avaliação da produção forrageira do campo pelo método Botanal. Foram verificadas melhores condições forrageiras para os cordeiros nascidos em agosto, que apresentaram maior peso e proporção na maioria dos cortes, assim como menor proporção de músculo na paleta e perna; apresentando maior conteúdo de tecido adiposo na maioria dos cortes da carcaça. Para os cordeiros nascidos em novembro, ocorreu maior relação músculo:gordura e músculo:osso na paleta e na perna, assim como maior relação músculo:gordura no costilhar. As condições nutricionais são responsáveis pelas diferenças nos pesos e rendimentos dos cortes, assim como na composição tecidual da carcaça, em cordeiros mantidos em regime de pasto, viabilizando o uso de época alternativa de nascimentos para incrementar a oferta de animais para o abate.The effect of alternative birth season on regional and tissue carcass composition of sheep was evaluated. Forty nine (49 Texel intact male lambs, born in two seasons (August and November, were kept under grazing and slaughtered with an average age of 129 and 164 days, respectively. Prior to slaughter forage production was measured using Botanal method. Lambs born in August had more favorable forage conditions, showing higher body weight and proportion in the majority of cuts, as well as lower proportion of shoulder and leg muscles showing higher adipose tissue content in the majority of carcass cuts. For lambs born in November, a higher muscle:fat and muscle:bone rate in shoulder and leg, as well as a higher ribcut muscle:fat rate. Nutritional

    A total of 40 marine mussel Perna viridis populations collected (2002–2009) from 20 geographical sites located in two busy shipping lanes namely the Straits of Malacca (10 sites; 16 populations) and the Straits of Johore (8 sites; 21 populations) and three populations (2 sites) on the east coast of Peninsular Malaysia, was determined for Cd, Cu, Fe, Ni, Pb and Zn concentrations. In comparison with the maximum permissible limits (MPLs) set by existing food safety guidelines, all metal concentrations found in all the mussel populations were lower than the prescribed MPLs. In terms of the provisional tolerable weekly intake prescribed by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and oral reference doses (ORDs) by the USEPA, all the studied metals (except for Pb) were unlikely to become the limiting factors or unlikely to pose a risk for the consumption of the mussel populations. The estimated daily intake (EDI) for average level mussel (ALM) and high level mussel (HLM) consumers of mussels was found to be lower than the ORD guidelines for Cd, Cu, Fe, Ni and Zn. Furthermore, the target hazard quotient (THQ) was found to be less than 1 for ALM consumers but higher than 1 for HLM consumers in some sites. Therefore, there were no potential human health risks to the ALM consumers of the mussels. However, for Pb THQ values, the Pb levels in some mussel populations could create a health risk problem. Present results indicate that the consumption amounts of mussels should be limited for minimizing potential health risks of heavy metals to the HLM consumers. - Highlights: • Human health risk assessments of heavy metals in Perna viridis were investigated. • All metals in the mussels were below the established seafood safety guidelines. • Pb in mussels could easily reach the percentage of prescribed PTWI value of Pb. • Potential health risk with Pb exposure was found for the mussel consumers. • Consumption rate of mussels should be limited to

    Full Text Available O presente estudo centra-se em verificar a influência da maturação na antropometria e aptidão física de jovens praticantes de voleibol, observando a correlação do estado maturacional com as demais variáveis. A amostra do estudo foi composta por 149 sujeitos (n= 149 de 8 a 14 anos. Para verificação da maturação, utilizou-se a idade cronológica e idade óssea como preditor maturacional através do método Grave-Brown (1976. Por sua vez, para as variáveis antropométricas, foram usadas as medidas de massa, estatura, índice ponderal, diâmetros biacromial e bi-crista ilíaca, perímetros de braço e perna, e perímetros de braço e de perna corrigidos, além dos testes físicos de agilidade, coordenação e força explosiva de membros inferiores e superiores. Ao observar a correlação entre a maturação e as demais variáveis, constatou-se que, no feminino, apenas o índice ponderal não apresentou correlação significativa e, no masculino, o índice ponderal, agilidade e coordenação. Em ambos os sexos, a estatura e diâmetros biacromial e bi-crista ilíaca apresentaram bons resultados. Assim, o estudo permite concluir que existe correlação entre o estágio maturacional, a variável força e variáveis antropométricas, ressaltando, ainda, a importância da avaliação de diferentes variáveis ao se trabalhar com orientação e promoção de talentos no desporto.

Trezentos e vinte e quatro pintos machos da linhagem Ross, com cinco dias de idade, foram distribuídos em um delineamento em parcelas subdivididas, considerando os tratamentos principais no esquema fatorial 3x3 inteiramente casualizado (três programas de alimentação: ad libitum, restrição precoce - 8 a 14 dias e restrição tardia - 29 a 35 dias; três níveis de temperatura: termoneutra, calor e frio. Os tratamentos secundários foram as idades das aves (seis idades: 7, 14, 21, 28, 35 e 42 dias. Não houve interação entre programa de alimentação e temperatura ou entre programa de alimentação, temperatura e idade para as características de desempenho dos frangos. Independentemente do programa de alimentação, houve efeito de temperatura para peso, ganho de peso, consumo de ração e conversão alimentar. O programa de alimentação afetou o peso e o ganho de peso das aves. Houve interação entre programa de alimentação e idade e entre temperatura e idade para peso vivo ao abate e peso do músculo da perna direita. Estas interações não foram significativas para peso do músculo da perna esquerda, área da secção transversal do músculo e relação peso do músculo/peso vivo ao abate. Conclui-se que a temperatura ambiente afeta o desempenho dos frangos de corte, porém não altera o número, diâmetro e freqüência de fibras musculares no músculo flexor longo do hálux. A restrição alimentar precoce pode ser adotada como prática de manejo, sem que se observem alterações do desempenho na idade de abate e nem na composição das fibras musculares esqueléticas dos frangos de corte.

Entre os métodos existentes, destacam-se a reeducação postural global (RPG, que promove o alongamento global das cadeias musculares, e o alongamento segmentar, que alonga um músculo ou grupo muscular específico. Este estudo visou comparar o alongamento segmentar e o global pela técnica de RPG quanto ao ganho de flexibilidade, ADM e força muscular. Trinta mulheres foram distribuídas aleatoriamente em três grupos (n=10 em cada: o grupo global fez alongamento de cadeias musculares; o grupo segmentar realizou alongamento segmentar; e o grupo controle não fez alongamento. Antes e depois do tratamento, em todos os grupos, foram avaliadas a ADM de extensão da perna, flexibilidade pelo teste 3o dedo-solo e força isométrica de flexão da perna em 45° e 90°. Os dois grupos experimentais realizaram oito sessões de alongamento de 30 minutos cada, duas vezes por semana. Toda a análise estatística foi realizada com pStretching exercises are prescribed to increase flexibility and range of motion (ROM. Two current stretching methods are the global posture reeducation (GPR, where muscle chains are stretched, and segmentary exercises, where a single muscle or muscle group is stretched. The aim of this study was to compare these two techniques, assessing their effects on improving flexibility, ROM and muscle strength. Thirty women were randomly distributed into three groups (n=10 each: global group performed stretching following GPR method; segment group performed segment stretching exercises; and control group did no exercise. Before and after treatment, in all groups, knee extension ROM, flexibility by means of the fingertip-to-floor test, and isometric muscular strength at 45° and 90° knee flexion were measured. Each treated group performed eight stretching 30-minute sessions for four weeks, twice a week. Data were statistically analysed and

The median age of the onset was 20 years. Characteristic features were sporadic occurrence, wasting confined to one limb, insidious onset with slow progression, stabilizing in 1 to 4 years, and absence of pyramidal signs. All the patients with upper limb involvement were male, however in our cases with lower limb amyotrophy there were no male preponderance. We observed wasting of the entire length of the lower limbs in six patients. There were nine cases with amyotrophy restricted to the leg and one with amyotrophy only in the thigh. In the upper limb in four cases the involvement was distal and in one patient the atrophy was proximal. The electromyographic features were suggestive of anterior horn disease not only in the affected limb but also, in some cases, in clinically uninvolved limb. Cervical or lumbar MRI was normal. MRI of the lower limb disclosed increased signal intensity in the gastrocnemius and soleus muscles in one patient suggesting denervation.Relatamos uma série consecutiva de 21 pacientes com amiotrofia de um só membro, denominada de amiotrofia monomélica.

    Full Text Available INTRODUÇÃO: A literatura técnica pertinente descreve elevadas frequências de lesões em bailarinas clássicas que dançam na ponta, no entanto, são escassas as informações sobre os efeitos crônicos permanentes desses agravos. OBJETIVO: Comparar a presença de SME em bailarinas com uso e sem uso de sapatilha de ponta. MÉTODOS: A pesquisa foi realizada no 27° Festival de Joinville, em Santa Catarina. Participaram do estudo 111 bailarinas, das quais 88 eram usuárias de sapatilha de ponta e 23 que não a utilizavam. Para obtenção das informações referentes aos SME e agravos específicos nos pés causados pela prática da dança foram utilizados protocolos específicos. RESULTADOS: As estruturas mais acometidas foram o joelho (29,7% ponta versus 39% sem ponta, coluna vertebral (26,4 ponta versus 22,0% sem ponta e tornozelo/pé (20,0% ponta versus 12,2% sem ponta. Através da taxa de Odds Ratio (OR e respectivos Intervalos de Confiança (IC95% foi identificado fator de proteção nos joelhos (0,24; IC95% - 0,09-0,64 e pernas (0,11; IC95% - 0,02-0,65 para bailarinas que usam sapatilha de ponta. Em contrapartida, constatou-se que o risco de ocorrência de agravos específicos nas estruturas dos pés é significativamente superior entre as bailarinas que utilizam sapatilha ponta. Neste caso, a ocorrência de joanetes (9,74; IC95% - 1,25-75,99, calos nos artelhos (3,46; IC95% - 1,29-9,27 e a associação dos três agravos (4,47; IC95% - 1,69-11,83 foram aquelas que apresentaram fator de risco aumentado quando comparados com bailarinas que não dançam na ponta. CONCLUSÃO: Em bailarinas da elite brasileira o uso de sapatilhas de ponta foi associado à menor ocorrência de SME na região do joelho e perna, porém, o uso da mesma está fortemente associado à presença de deformidades nos pés.

  15. Effects of solar PAR and UV radiation on tropical biofouling communities

    2010-03-08

    We investigated the effect of solar ultraviolet radiation (UVR) and photosynthetically active radiation (PAR) on the development of tropical micro- and macrofouling communities for 30 d. The experimental design involved 3 treatments: full spectrum (PAR+UVR), PAR only, and minimal light (reduced PAR and UVR). Terminal restriction fragment length polymorphism analysis demonstrated that different light conditions resulted in the formation of highly different microbial communities. The lowest densities of bacteria were found under the full spectrum treatment, while the lowest densities of diatoms were found in the minimal light treatment. Macrofouling communities consisted of 13 species and differed among light treatments. In the presence of UVR, communities had low species diversity, evenness, and richness, while in minimal light and PAR treatments, communities had high species diversity, evenness, and richness. Similarity percentage (SIMPER) analysis revealed that the tubeworm Hydroides elegans, the alga Ulva (Enteromorpha) sp., and the bivalve Perna viridis were the species responsible for most of the dissimilarities in macrofouling communities among treatments. While densities of H. elegans were similar in the PAR and minimal light treatments, this polychaete had higher growth rates under minimal light conditions. We conclude that UVR and PAR directly control the development of shallow micro- and macrofouling communities by inhibiting the recruitment and growth of sensitive species and promoting the growth of resistant species, but also that these forms of solar radiation influence the surface cues available to competent larvae by altering the development of the microbial community.

    This overview of systematic reviews (SRs) aims to evaluate critically the evidence regarding the adverse effects of herbal medicines (HMs). Five electronic databases were searched to identify all relevant SRs, with 50 SRs of 50 different HMs meeting our inclusion criteria. Most had only minor weaknesses in methods. Serious adverse effects were noted only for four HMs: Herbae pulvis standardisatus, Larrea tridentate, Piper methysticum and Cassia senna. The most severe adverse effects were liver or kidney damage, colon perforation, carcinoma, coma and death. Moderately severe adverse effects were noted for 15 HMs: Pelargonium sidoides, Perna canaliculus, Aloe vera, Mentha piperita, Medicago sativa, Cimicifuga racemosa, Caulophyllum thalictroides, Serenoa repens, Taraxacum officinale, Camellia sinensis, Commifora mukul, Hoodia gordonii, Viscum album, Trifolium pratense and Stevia rebaudiana. Minor adverse effects were noted for 31 HMs: Thymus vulgaris, Lavandula angustifolia Miller, Boswellia serrata, Calendula officinalis, Harpagophytum procumbens, Panax ginseng, Vitex agnus-castus, Crataegus spp., Cinnamomum spp., Petasites hybridus, Agave americana, Hypericum perforatum, Echinacea spp., Silybum marianum, Capsicum spp., Genus phyllanthus, Ginkgo biloba, Valeriana officinalis, Hippocastanaceae, Melissa officinalis, Trigonella foenum-graecum, Lagerstroemia speciosa, Cnicus benedictus, Salvia hispanica, Vaccinium myrtillus, Mentha spicata, Rosmarinus officinalis, Crocus sativus, Gymnema sylvestre, Morinda citrifolia and Curcuma longa. Most of the HMs evaluated in SRs were associated with only moderately severe or minor adverse effects.

    2004-01-01

    Concentration of butyltin compounds (BTs), including tributyltin (TBT), dibutyltin (DBT) and monobutyltin (MBT) and total tin (ΣSn) were determined in green mussel (Perna viridis), 10 species of muscle fish and sediment from coastal waters of Malaysia. BTs were detected in all these samples ranging from 3.6 to 900 ng/g wet wt., 3.6 to 210 ng/g wet wt., and 18 to 1400 ng/g dry wt. for mussels, fish and sediments, respectively. The concentrations of BTs in several locations of this study were comparable with the reported values from some developed countries and highest among Asian developing nations. Considerable concentration of BTs in several locations might have ecotoxicological consequences and may cause concern to human health. The parent compound TBT was found to be highest than those of its degradation compounds, DBT and MBT, suggesting recent input of TBT to the Malaysian marine environment. Significant positive correlation (Spearman rank correlation: r 2 =0.82, P<0.0001) was found between BTs and ΣSn, implying considerable anthropogenic input of butyltin compounds to total tin contamination levels. Enormous boating activities may be a major source of BTs in this country, although aquaculture activities may not be ignored. - Lack of any regulation of TBT clearly resulted in a heavy contamination of BTs in Malaysia

    In the present study, a straightforward approach was validated for the analysis of pharmaceutically active compounds and endocrine-disrupting chemicals in the mollusk tissues, with a focus on two species commonly consumed in Southeast Asia (green mussels: Perna viridis; lokan clams: Polymesoda expansa). This approach relied on a simple solvent extraction (shaker table) followed by direct injection in liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). This "cleanup-free" approach was made possible by the use of isotopically labeled surrogates (to correct for matrix effects) and a post-column switch on the LC-MS/MS system (to remove potential interfering material). Altogether, relative recoveries were satisfactory for 36 out of 44 compounds (26-163% range) and excellent for 27 out of 44 compounds (79-107% range). Method detection limits (MDLs) were usually expressed in the nanogram per gram wet weight (ww) range and below. The method was successfully applied to 16 batches of green mussel samples collected in Singapore coastal waters. Trace levels of six compounds were detected in mussel tissues: caffeine (0.22-1.55 ng g(-1) ww), carbamazepine (

    The green-lipped mussel, Perna canaliculus is recognised as a bioindicator of coastal contamination in New Zealand (NZ). Mussels (shell length 60-80 mm) were collected from three intertidal areas of Canterbury in the South Island of NZ prior to extreme earthquake disturbances on 22nd February 2011, and 9 months later in October 2011. Trace elements, including arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn), were measured in the gills, digestive gland, foot and mantle. Metal levels in tissues were site specific, and mostly unaffected by earthquake disturbances. Physiological biomarkers were negatively affected by earthquake disturbances and mussels from the Port of Lyttelton had higher negative scope for growth post-earthquake. Metallothionein-like protein in the digestive gland correlated with metal content of tissues, as did catalase activity in the gill and lipid peroxidation values for the digestive gland. This research demonstrates that physiological and other biomarkers are effective at detecting the effects of multiple stressors following seismic disturbances.

    An interaction between the incident light and the structural architecture within the shell of Asian green mussel (Perna viridis) induces observable pearlescent colors. In this paper, we investigate the influence of the structural architecture on the expressed colors. After a removal of the organic binder, small flakes from crushed shells show vivid rainbow reflection under an optical microscope. An individual flake expresses vivid color under a bright-field illumination while become transparent under a dark-field illumination. The expressed colors of the aragonite flakes are directly associated with its structural architecture. The flakes with aragonite thickness of 256, 310, and 353 nm, respectively, appear blue, green, and red under an optical microscope. The spectral simulation corroborates the experimentally observed optical effects as the flakes with thicker aragonite layers selectively reflected color with longer wavelengths. Flakes with multiple aragonite thicknesses expressed multi-color as the upper aragonite layers allow reflected colors from the lower layers to be observed. Copyright © 2015 Elsevier Inc.

    Full Text Available Esta pesquisa analisou o Brexit em uma perspectiva histórica, focando a conturbada relação entre a Europa continental e o Reino Unido ao longo do século XX, com ênfase no período pós Segunda Guerra Mundial. Foi utilizado o conceito de path dependency para argumentar sobre o papel de fatores históricos e decisões do passado, embora tomados em outras circunstâncias, ainda com força para influenciar o presente, para entender o Brexit. A premissa básica que será apresentada no ensaio é que o Reino Unido nunca participou de fato da ideia da Europa e sempre se viu como um país diferente por sua história e seu papel no mundo. Quando entrou, foi com uma perna só, a outra sempre ficou atrás, inclusive devido às especificidades de sua estrutura econômica herdada do passado, em particular no que diz respeito à agricultura. Desta forma, defende-se que, embora longe de ter sido inevitável, se tratou de um fenômeno limitado ao Reino Unido que tinha pouquíssima probabilidade de se repetir em outros países da União Europeia.

    During the months of January-February and May-June 2013 coinciding with the red tide occurrence in Kota Kinabalu, Sabah, Malaysia, six episodes involving 58 cases of paralytic shellfish poisoning (PSP) or saxitoxin (STX) poisoning and resulting in four deaths were reported. Many of them were intoxicated from consuming shellfish purchased from the markets, whereas others were intoxicated from eating shellfish collected from the beach. Levels of STX in shellfish collected from the affected areas were high (mean 2,920 ± 780 and 360 ± 140 µg STX equivalents/100 g shellfish meat respectively for the two periods). The count of toxic dinoflagellates ( Pyrodinium bahamense var compressum ) of the sea water sampled around the coast was also high (mean 34,200 ± 10,300 cells/L). Species of shellfish containing high levels of STX were Atrina fragilis , Perna viridis , and Crassostrea belcheri . The age of victims varied from 9 to 67 years. Symptoms presented were typical of PSP, such as dizziness, numbness, vomiting, and difficulty in breathing. Recommended steps to prevent or reduce PSP in future red tide season include better monitoring of red tide occurrence, regular sampling of shellfish for determination of STX level, wider dissemination of information on the danger of eating contaminated shellfish among the communities, fishermen, and fishmongers.

    Microplastic pollution is increasingly becoming a great environmental concern worldwide. Microplastics have been found in many marine organisms as a result of increasing plastic pollution within marine environments. However, the relationship between micoplastics in organisms and their living environment is still relatively poorly understood. In the present study, we investigated microplastic pollution in the water and the mussels (Mytilus edulis, Perna viridis) at 25 sites along the coastal waters of China. We also, for the first time, conducted an exposure experiment in parallel on the same site using M. edulis in the laboratory. A strong positive linear relationship was found between microplastic levels in the water and in the mussels. Fibers were the dominant microplastics. The sizes of microplastics in the mussels were smaller than those in the water. During exposure experiments, the abundance of microbeads was significantly higher than that of fibers, even though the nominal abundance of fibers was eight times that of microbeads. In general, our results supported positive and quantitative correlations of microplastics in mussels and in their surrounding waters and that mussels were more likely to ingest smaller microplastics. Laboratory exposure experiment is a good way to understand the relative impacts of microplastics ingested by marine organisms. However, significant differences in the results between exposure experiments and field investigations indicated that further efforts are needed to simulate the diverse environmentally relevant properties of microplastics.

    2018-03-01

    Full Text Available The therapeutic benefits of Greenshell™ mussel (GSM; Perna canaliculus preparations have been studied using in vitro test systems, animal models, and human clinical trials focusing mainly on anti-inflammatory and anti-arthritic effects. Activity is thought to be linked to key active ingredients that include omega-3 polyunsaturated fatty acids, a variety of carotenoids and other bioactive compounds. In this paper, we review the studies that have been undertaken in dogs, cats, and horses, and outline new research directions in shellfish breeding and high-value nutrition research programmes targeted at enhancing the efficacy of mussel and algal extracts. The addition of GSM to animal diets has alleviated feline degenerative joint disease and arthritis symptoms, and chronic orthopaedic pain in dogs. In horses, GSM extracts decreased the severity of lameness and joint pain and provided improved joint flexion in limbs with lameness attributed to osteoarthritis. Future research in this area should focus on elucidating the key active ingredients in order to link concentrations of these active ingredients with their pharmacokinetics and therapeutic effects. This would enable consistent and improved efficacy from GSM-based products for the purpose of improved animal health.

  19. The genetic architecture of hybridisation between two lineages of greenshell mussels.

    2015-03-01

    A multidisciplinary approach has identified sigmoidal genetic clines on the east and west coasts in central New Zealand where low-density ecological interactions occur between northern and southern lineages of the endemic greenshell mussel, Perna canaliculus. The sigmoidal clines indicate the existence of a mussel hybrid zone in a region of genetic discontinuities for many continuously distributed coastal taxa, in particular marine invertebrates. Examination of the genetic architecture of the hybrid zone revealed the differential contribution of individual microsatellite loci and/or alleles to defining the zone of interaction and no evidence of increased allelic richness or heterozygosity inside versus outside the hybrid zone. Genomics cline analysis identified one locus in particular (Pcan1-27) as being different from neutral expectations, thereby contributing to lineage differentiation. Estimates of contemporary gene flow revealed very high levels of within-lineage self-recruitment and a hybrid zone composed mostly (~85%) of northern immigrants. Broad scale interpretation of these results is consistent with a zone of genetic interaction that was generated between 0.3 and 1.3 million years before present at a time of pronounced global sea-level change. At that time, the continuous distribution of the greenshell mussel was split into northern and southern groups, which differentiated to become distinct lineages, and which have subsequently been reunited (secondary contact) resulting in the generation of the hybrid zone at ~42°S.

Foram utilizadas poedeiras Isa Brown com idade entre 30 e 32 semanas alojadas em galpões de escala reduzida e distorcida. As aves foram criadas durante 28 dias, em baias com cama de maravalha, poleiro e ninho. Foram avaliados dois tamanhos de grupos (6 e 12 aves e duas densidades de criação (774 e 1.440 cm² por ave, em arranjo fatorial com três repetições. Em amostras de vídeo de 15 min, foram registrados as frequências e os tempos de expressão dos comportamentos: arrumar penas, banho de areia, bater asas, beber água, bicar, coçar a cabeça, ciscar, comer, empoleirar, esticar perna, perseguir, sentar e visitar o ninho. Foram observados efeitos significativos dos tratamentos e da interação entre eles. O grupo de seis aves manifestou aumento da frequência de comportamentos que indicam maior frustração das aves, independentemente da densidade. O tamanho de grupo é o fator mais importante para o bem-estar das aves.

    Full Text Available Analisou-se o perfil dos trabalhadores do ramo de atividade Correios que receberam benefícios auxílio-doença, no Brasil, em 2008. Os dados originaram-se do Sistema Único de Benefícios (SUB e do Cadastro Nacional de Informações Sociais (CNIS. A incidência foi de 556,5 benefícios por 10 mil empregados, e as principais causas de afastamento foram traumatismos, doenças osteomusculares e transtornos mentais. Locais de traumas mais notificados foram joelho e perna, punho e mão, tornozelo e pé, ombro e braço, com as maiores incidências em homens. Mulheres foram as mais acometidas por doenças osteomusculares e transtornos mentais. A duração do auxílio-doença foi maior entre homens, havendo aumento da incidência de benefícios com o envelhecimento. Os estados de Mato Grosso do Sul, Goiás, Santa Catarina foram os de maiores incidências, e a despesa previdenciária foi de R$ 1.847,00. É possível que a atividade postal apresente riscos adicionais de acidentes em extremidades devido ao excesso de peso carregado por longas distâncias, risco de assaltos ou de acidente por mordedura de cães.

Standard therapy regimens produce a 5-year relative survival rate of only 69%, with the critical need to increase the treatment-success rate of this patient population presenting at diagnosis with a median age of 66 years and many comorbidities. The evidence that an impaired immune system favors the development of NHL has opened the stage for new therapeutics, and specifically for the adoptive transfer of ex vivo-expanded antigen-specific T-cells. In this review, we discuss how T-cells specific for viral-associated antigens, nonviral-associated antigens expressed by the tumor, T-cells redirected through the expression of chimeric antigen receptors, and transgenic T-cell receptors against tumor cells have been developed and used in clinical trials for the treatment of patients with NHLs.

  7. Immunotoxicity in green mussels under perfluoroalkyl substance (PFAS) exposure: Reversible response and response model development.

    The immunotoxicity of 4 commonly detected perfluoroalkyl substances (PFASs), namely, perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA) was investigated by measuring biomarkers of the immune profile of green mussels, Perna viridis. The biomarkers included neutral red retention, phagocytosis, and spontaneous cytotoxicity, all of which were tested on mussel hemocytes. Hemocytes are an important component of the invertebrate immune system. We found that exposure to PFASs could lead to reduced hemocyte cell viability and suppress immune function by up to 50% of normal performance within the experimental exposure range. The results indicate that PFASs have an immunotoxic potential and thus could pose severe health risks to aquatic organisms. The reported immunotoxicity is likely to result from the compounds' direct and indirect interactions with the hemocyte membrane, and therefore likely to affect the functionality of these cells. The immunotoxic response was found to be related to the organism's burden of PFASs, and was reversible when the compounds were removed from the test organisms. Based on this relationship, models using an organism's PFAS concentration and bioaccumulation factor (BAF) as the independent variables were established to quantify PFAS-induced immunotoxicity. The models help us to gain a better understanding of the toxic mechanism of PFASs, and provide a tool to evaluate adverse effects for the whole group of compounds with one mathematical equation.

    This is the first detailed report of Nematopsis spp. in Thai bivalves. A monthly survey was conducted on 7 species of commercial bivalves from Chonburi province, on the eastern seaboard of Thailand, from November 2000 to November 2001 to investigate the prevalence of the apicomplexan parasite Nematopsis Schneider, 1892. Nematopsis spp. sporozoites were found in the cultivated bivalves Arcuatula arcuatula, Anadara granosa and Perna viridis as well as the locally harvested Paphia undulata. They were not found in Donax faba, Meretrix meretrix or Saccostrea cucullata. Using light microscopy, we were able to identiby 4 oocyst morphotypes of the gregarine Nematopsis spp. Prevalence of Nematopsis spp. during the 13 mo sampling period was highest in A. arcuatula (91.8%; n = 110) and lowest in A. granosa (59.2%; n = 130). The morphology of the oocysts differed between hosts, with an average (x +/- SD) length/width of 16.28 +/- 0.64/12.01 +/- 0.35 microm (n = 50) for A. arcuatula, 16.90 +/- 0.71/12.69 +/- 0.33 microm (n = 50) for A. granosa, 17.61 +/- 0.69/12.72 +/- 0.36 microm (n = 50) for P. viridis, and 11.21 +/- 0.62/8.55 +/- 0.52 microm (n = 50) for P. undulata. Identification of oocysts of these apicomplexan gregarines to species was not attempted. The prevalence of infection in relation to habitat and time of sampling is discussed.

    Full Text Available A criação intensiva de frangos de corte, aliada à nutrição e ao melhoramento genético com foco no ganho de peso, tem resultado em índices crescentes da incidência de problemas de pernas. Dentre as variáveis que podem contribuir para a ocorrência destes problemas, estão a linhagem e o sexo. Neste contexto, avaliaram-se propriedades geométricas e mecânicas de tíbias de frangos de corte, machos e fêmeas, de três linhagens comerciais no periodo final de crescimento, entre 21 e 42 dias. As características geométricas refletem a resposta adaptativa dos ossos, com relação direta entre suas dimensões e o peso vivo das aves. Quanto às características mecânicas obtidas de ensaios de flexão, observa-se o que o julgamento da robustez óssea pode levar a conclusões diferentes dependendo da variável mecânica considerada. Aves mais pesadas, com ossos maiores, suportam forças maiores na flexão. Entretanto, quando variáveis de resistência intrínsecas do material são consideradas, como resistência à flexão, observa-se que a linhagem mais pesada não apresenta resistência à flexão significativamente diferente das demais. O mesmo ocorre entre machos (mais pesados e fêmeas. Logo, aves mais pesadas, com tíbias tão resistentes quanto às das aves mais leves, podem ser mais susceptíveis a problemas estruturais de pernas.The intensive rearing of broilers, combined with nutrition and genetic improvement focused on weight gain has resulted in increasing rates of leg problems.

    Full Text Available A doença pulmonar obstrutiva crônica é progressiva, debilitante e diagnosticada após longa história de piora gradual. A dispnéia é o sintoma que mais interfere na execução das atividades profissionais, familiares, sociais e da vida diária dos pacientes com doença pulmonar obstrutiva crônica, levando-os ao sedentarismo e à queda na qualidade de vida. O objetivo deste artigo é abordar as limitações funcionais a que esses pacientes estão sujeitos, durante a realização de suas atividades da vida diária, e orientações para que os profissionais da saúde possam cuidar desses pacientes a fim de que obtenham uma maior funcionalidade. As orientações sobre o uso das técnicas de conservação de energia vêm sendo utilizadas nos programas de reabilitação pulmonar e também deveriam ser difundidas nos ambulatórios e hospitais. As atividades funcionais humanas envolvem as pernas e os braços, sendo estes últimos utilizados extensivamente para realizar atividades simples e complexas do cotidiano. Alguns estudos mostraram que os exercícios de braço não sustentados causam assincronia toracoabdominal e dispnéia em tempo mais curto e com menor consumo de oxigênio quando comparados com os exercícios de pernas. Tarefas simples podem apresentar consumo de oxigênio e ventilação minuto altos, justificando a sensação de dispnéia relatada pelos pacientes. Devido a isso, é conveniente adotar uma avaliação do impacto da incapacidade sobre a vida diária dos pacientes com doença pulmonar obstrutiva crônica. São discutidas e indicadas as técnicas de conservação de energia apropriadas como ferramenta para minimizar o desconforto desses pacientes.Chronic obstructive pulmonary disease is a progressive and debilitating disease that is typically diagnosed only after a long period of gradual worsening.

    2016-10-01

    Powerful ionised AGN-driven outflows, commonly detected both locally and at high redshift, are invoked to contribute to the co-evolution of SMBH and galaxies through feedback phenomena. Our recent works (Brusa+2015; 2016; Perna+2015a,b) have shown that the XMM-COSMOS targets with evidence of outflows collected so far ( 10 sources) appear to be associated with low X-ray kbol corrections (Lbol /LX ˜ 18), in spite of their spread in obscuration, in the locations on the SFR-Mstar diagram, in their radio emission. A higher statistical significance is required to validate a connection between outflow phenomena and a X-ray loudness. Moreover, in order to validate their binding nature to the galaxy fate, it is crucial to correctly determine the outflow energetics. This requires time consuming integral field spectroscopic (IFS) observations, which are, at present, mostly limited to high luminosity objectsThe study of SDSS data offers a complementary strategy to IFS efforts. I will present physical and demographic characterization of the AGN-galaxy system during the feedback phase obtained studying a sample of 500 X-ray/SDSS AGNs, at z<0.8. Outflow velocity inferred from [OIII]5007 emission line profile has been related to optical (e.g., [OIII] and bolometric luminosities, Eddington ratio, stellar velocity dispersion) and X-ray properties (intrinsic X-ray luminosity, obscuration and X-ray kbol correction), to determine what drives ionised winds. Several diagnostic line ratios have been used to infer the physical properties of the ionised outflowing gas. The knowledge of these properties can reduce the actual uncertainties in the outflow energetics by a factor of ten, pointing to improve our understanding of the AGN outflow phenomenon and its impact on galaxy evolution.

    Arsenic (As) and mercury (Hg) associated with geothermally influenced lakes and rivers represent a potential health risk to communities where wild-caught food is consumed. The Rotorua Lakes region of New Zealand has extensive natural geothermal activity and a large proportion (35%) of indigenous Māori population, for whom wild food gathering is an important cultural activity. The aim of this study was to measure selected heavy metal and organochlorine (OC) concentrations in important local fish and shellfish species and assess the potential health risk to the local population of consuming these species. Following U.S. Environmental Protection Agency (EPA) protocols, consumption limits were calculated based on both excess lifetime cancer risk and noncancer risk. These were compared with local consumption rates, which were determined by questionnaire (n = 19). Median and 95th percentile contaminant concentrations were calculated to approximate random and most extreme contaminant consumption scenarios. Only Hg concentrations exceeded established Food Standards Australia New Zealand (FSANZ) guideline values of 0.5 mg/kg, namely, for rainbow trout (Oncorhynchus mykiss; 62% of the study sites) and koura (freshwater crayfish; Paranephrops planifrons; 25% of sites). The major risk was from consumption of trout, where the local consumption rate (1.5 meals/mo) exceeded the consumption limit of 0.9 meals/mo (median data) and 0.4 meals/mo (95th percentile data). Shellfish--pipi (Paphies australis) and mussel (Perna canaliculus)--collected from the only estuarine site also had local consumption rates (3.5 meals/mo) above calculated consumption limits (2.6 and 2.9 meals/mo, respectively). Our results, while based on a limited sample size and therefore exploratory in nature, nevertheless provide the basis for developing consumption guidelines. This study makes a significant contribution to broadening our understanding of the complexities of managing customary fisheries.

    Full Text Available Neste estudo foram avaliados três planos nutricionais para codornas de 1 a 42 dias de idade quanto ao desempenho, qualidade de carcaça e viabilidade econômica. Um total de 210 codornas européias foram distribuído em três tratamentos em um delineamento inteiramente casualizado com cinco repetições e 14 aves em cada parcela. Foram testados os três tratamentos seguintes: plano nutricional 1 - uma dieta, de 1 a 42 dias de idade; Plano nutricional 2 - duas dietas, de 1 a 21 e 22 a 42 dias de idade; e plano nutricional 3 - três dietas, de 1 a 14, 15 a 35 e 36 a 42 dias de idade. Os dados foram submetidos a análise de variância e as médias foram comparadas pelo teste de Student Newman Keuls (SNK, ao nível de probabilidade de 5%. Aos 42 dias de idade, uma ave de cada sexo, de cada unidade experimental, foi abatida para avaliar os rendimentos de carcaça, peito, pernas e gordura abdominal. Os planos nutricionais por fase de criação com duas ou três dietas proporcionaram desempenho zootécnico semelhantes e melhor conversão alimentar quando comparado com o plano nutricional com apenas uma dieta. As características de carcaça estudadas não diferiram entre os tratamentos. O plano nutricional com três dietas proporcionou a melhor viabilidade econômica. O melhor plano nutricional para codornas de corte foi o que continha três tipos de rações, pois proporcionou um custo menor com ração por quilograma de codorna produzida sem comprometer o desempenho ou características de carcaça.

The patient returned to the service six years after the end of treatment, with pain in hands and legs. He was investigated, and the serological monitoring showed an important increase in anti-phenolic glycolipid serum levels. A neural recurrence was suspected, since the patient had no new skin lesions. A new biopsy in the right ulnar nerve showed a bacilloscopy of 2 +, compatible with relapse. This is a literature review of the etiological, clinical, propedeutical and diagnostic aspects of this situation so poorly understood.O presente artigo relata um caso de recidiva, com manifestação neural isolada, em paciente multibacilar previamente tratado com poliquimioterapia para multibacilar 24 doses. O paciente retorna ao serviço, seis anos depois do fim do tratamento, com dores em mãos e pernas. Na investigação, o acompanhamento da sorologia anti-glicolipídeo fenólico 1 demonstrou aumento importante dos níveis séricos, e foi aventada a hipótese de recidiva neural, já que o paciente não apresentava lesões cutâneas novas. Uma nova biópsia, em nervo ulnar direito, demonstrou baciloscopia de 2+, compatível com recidiva.

    Xue, Ming; Ke, Cai-Huan

    2012-07-01

    An indoor exposure experiment with juvenile Babylonia areolata was conducted to study its survival, growth, cadmium (Cd) accumulation, metallothionein (MT) induction, and glycogen content as well as the DNA integrity of hepatopancreas tissue. The juveniles were starved or fed with mussel (Perna viridis) or clamworm (Perinereis aibuhitensis), and exposed to 50 microg x L(-1) of Cd2+ for 10 weeks. Prolonged starvation and simultaneous exposure to Cd reduced the survival rate of B. areolata, and its glycogen was mobilized in great extent. Feeding with P. viridis or P. aibuhitensis helped the B. areolata to combat Cd toxicity and lessen mortality. After exposed to Cd, the damage of the DNA integrity of hepatopancreas tissue for the B. areolata fed with P. viridis or P. aibuhitensis could be recovered with time, but not for the starved B. areolata. Prolonged starvation caused tissue atrophy and led to Cd accumulation and MT increase, while feeding with P. viridis or P. aibuhitensis increased the B. areolata mass and lowered the Cd accumulation and MT level because of the tissue dilution effect. The B. areolata fed with P. viridis had better growth and lower Cd content than that fed with P. aibuhitensis. This study indicated that starvation intensified the toxicity of Cd to B. areolata, while prey type had significant effects on the growth rate of the B. areolata and indirectly affected its Cd accumulation, MT induction, and glycogen consumption. It was suggested that when using gastropods such as B. areolata as the indicator species to monitor marine environmental pollution, it would be necessary to consider the effects of habitat ecological data including food richness and prey type. Moreover, in the high-density cultivation of B. areolata in factory, rational feeding and periodic measurement of Cd concentration in seawater should be made.

    Full Text Available INTRODUÇÃO: A fibrodisplasia ossificante progressiva é uma doença rara do tecido conjuntivo, caracterizada por ossificação disseminada em tecidos moles e alterações congênitas das extremidades. Seu inicio ocorre na infância e o envolvimento progressivo axial e da região proximal dos membros leva a uma conseqüente imobilização e deformação articular. RELATO DE CASO: Paciente de 24 anos de idade, sexo masculino, apresentando dor nas articulações e dificuldade para andar e, principalmente, ao sentar-se. A partir dos nove anos, referiu episódios recorrentes de dor, rigidez das pernas e da coluna, evoluindo posteriormente para todo corpo. Ao exame físico foi evidenciada limitação funcional global do paciente, com rigidez distribuída em todo o corpo, ausência de mobilidade do esqueleto axial e redução da mobilidade das articulações periféricas. DISCUSSÃO: Os sintomas da FOP são variáveis, com a maioria dos doentes apresentando calcificação das partes moles antes dos dez anos de idade. As primeiras manifestações localizam-se na coluna vertebral e nas articulações proximais. O quadro clínico caracteriza-se por sinais inflamatórios, por vezes acompanhados de expansões dolorosas, endurecimento dos tecidos periarticulares e perda progressiva da capacidade funcional da área afetada, sendo sua progressão no sentido axial-caudal e proximal-distal. As radiografias convencionais documentam freqüentemente as anomalias esqueléticas constitucionais e as ossificações e anquiloses articulares correspondentes à história natural da doença.

  16. Mathematical and numerical study of nonlinear hyperbolic equations: model coupling and nonclassical shocks

    This thesis concerns the mathematical and numerical study of nonlinear hyperbolic partial differential equations. A first part deals with an emergent problematic: the coupling of hyperbolic equations. The pursued applications are linked with the mathematical coupling of computing platforms, dedicated to an adaptative simulation of multi-scale phenomena. We propose and analyze a new coupling formalism based on extended PDE systems avoiding the geometric treatment of the interfaces. In addition, it allows to formulate the problem in a multidimensional setting, with possible covering of the coupled models. This formalism allows in particular to equip the coupling procedure with viscous regularization mechanisms, useful in the selection of natural discontinuous solutions. We analyze existence and uniqueness in the framework of a parabolic regularization a la Dafermos. Existence of a solution holds true under very general conditions but failure of uniqueness may naturally arise as soon as resonance occurs at the interfaces. Next, we highlight that our extended PDE framework gives rise to another regularization strategy based on thick interfaces. In this setting, we prove existence and uniqueness of the solutions of the Cauchy problem for initial data in L ∞ . The main tool consists in the derivation of a flexible and robust finite volume method for general triangulation which is analyzed in the setting of entropy measure-valued solutions by DiPerna. The second part is devoted to the definition of a finite volume scheme for the computing of nonclassical solutions of a scalar conservation law based on a kinetic relation. This scheme offers the feature to be stricto sensu conservative, in opposition to a Glimm approach that is only statistically conservative. The validity of our approach is illustrated through numerical examples. (author)

    The mitochondrial gene cytochrome c oxidase subunit I (COI) was sequenced from Mytella charruana (N = 243) at 10 Brazilian coastal localities to search for cryptic species, doubly uniparental inheritance and investigate genetic population structure and demography. Three haplogroups were found: two matrilinear (A and B) in males and females, and one patrilinear (C) found only in males. The p-distances were 0.0624 (A and B), 0.2097 (A and C) and 0.2081 (B and C). Coalescence of M. charruana occurred around 12.5 Mya, and the origins of the lineages were 3.4 and 4 Mya (matrilinear A and B) and 51.2 Mya (patrilinear), which split before the separation of the genera Perna and Mytella. All individuals from the northern coast of Brazil belonged to haplogroup A, whereas haplogroup B predominated among individuals from the eastern and northeastern coasts, with one exception, Goiana. Haplogroup C was found in males from the northern to the eastern coast. GenBank sequences of M. charruana from Colombia, Ecuador and four populations introduced to the USA joined Brazilian haplogroup B. Nuclear gene 18S-ITS1 sequences confirmed that all specimens belong to the same species. Four populations from the northern coast of Brazil were homogenous with evidence of recent population expansion. All populations from the northeastern and eastern coasts of Brazil were significantly structured (pairwise FST and AMOVA). The heterogeneity among Brazilian populations requires that relocation for aquaculture be preceded by genetic identification of the haplogroups. Differences in salinity and temperature may have selected for distinct lineages of mussels and changing conditions in coasts and estuaries may allow only resistant lineages of mussel to persist with the loss of others. In the light of global climate change, more detailed data on temperature, pH, salinity and local currents could help explain the genetic structuring observed among populations of Brazilian M. charruana.

    Full Text Available BACKGROUND: Marine epibiotic bacteria produce bioactive compounds effective against microbial biofilms. The study examines antibiofilm ability of a protein obtained from a tropical marine strain of Bacillus licheniformis D1. METHODOLOGY/PRINCIPAL FINDINGS: B. licheniformis strain D1 isolated from the surface of green mussel, Perna viridis showed antimicrobial activity against pathogenic Candida albicans BH, Pseudomonas aeruginosa PAO1 and biofouling Bacillus pumilus TiO1 cultures. The antimicrobial activity was lost after treatment with trypsin and proteinase K. The protein was purified by ultrafiltration and size-exclusion chromatography. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE and matrix assisted laser desorption/ionization-time of flight (MALDI-TOF analysis revealed the antimicrobial agent to be a 14 kDa protein designated as BL-DZ1. The protein was stable at 75°C for 30 min and over a pH range of 3.0 to 11.0. The sequence alignment of the MALDI-fingerprint showed homology with the NCBI entry for a hypothetical protein (BL00275 derived from B. licheniformis ATCC 14580 with the accession number gi52082584. The protein showed minimum inhibitory concentration (MIC value of 1.6 µg/ml against C. albicans. Against both P. aeruginosa and B. pumilus the MIC was 3.12 µg/ml. The protein inhibited microbial growth, decreased biofilm formation and dispersed pre-formed biofilms of the representative cultures in polystyrene microtiter plates and on glass surfaces. CONCLUSION/SIGNIFICANCE: We isolated a protein from a tropical marine strain of B. licheniformis, assigned a function to the hypothetical protein entry in the NCBI database and described its application as a potential antibiofilm agent.

    Full Text Available Foram estudadas 386 crianças entre seis e 59 meses de idade, residentes em área de baixa renda do Município de Pelotas, Rio Grande do Sul, com o objetivo de avaliar a associação entre o déficit de peso para estatura e o perímetro abdominal. Foram tomadas 13 medidas antropométricas (peso, estatura, estatura tronco-cefálica, quatro perímetros, quatro pregas cutâneas e duas larguras. Calcularam-se as áreas muscular, adiposa e total do braço, e o comprimento de pernas. Índices de proporcionalidade corporal foram obtidos, dividindo-se os valores das variáveis antropométricas pela respectiva estatura. Déficits de estatura para idade, peso para idade e peso para estatura foram de 25,9%, 14,4% e 3,5%, respectivamente. O perímetro abdominal dividido pela estatura mostrou-se elevado em crianças baixas e menos pesadas. Uma redução média de 2 cm no perímetro abdominal entre crianças pelotenses sem déficit nutricional elevaria a prevalência de déficit de peso para estatura dos atuais 3,5% para 7,0%. As baixas prevalências de déficit de peso para estatura na presença de elevados déficits de estatura para idade, conforme descrito em diversos estudos brasileiros, podem ser parcialmente explicadas por aumentos no perímetro abdominal.

Wound-related pain is often associated with skin ulcers and negatively impacts both the patient’s quality of life and, indirectly, wound healing. Pain management is an ongoing issue in the elderly, and remains underestimated and undertreated in this fragile population. Recent guidelines suggest the use of opioids as the frontline treatment of moderate and severe pain in nononcological pain in the elderly. However, due to the concerns of adverse reactions, drug interactions, and addiction, clinicians frequently hesitate to prescribe opioids. This case report describes an elderly diabetic patient with multiple ulcers of the lower limbs suffering wound-related pain. In our report, oxycodone/naloxone has proved to be an effective and safe drug, providing pain relief as well as increased compliance when redressing wounds and faster healing compared to that in similar patients. Our case provides anecdotal evidence, supported by other studies, to justify future, larger studies on chronic pain using this therapy.

    Differences in the accumulation of mercury (Hg) in five species of marine bivalves, including scallops Chlamys nobilis, clams Ruditapes philippinarum, oysters Saccostrea cucullata, green mussels Perna viridis, and black mussels Septifer virgatus, were investigated. The bivalves displayed different patterns of Hg accumulation in terms of the body concentrations of methylmercury (MeHg) and total Hg (THg), as well as the ratio of MeHg to THg. Parameters of the biodynamics of the accumulation of Hg(II) and MeHg could reflect the species-dependent Hg concentrations in the bivalves. With the exception of black mussels, we found a significant relationship between the efflux rates of Hg(II) and the THg concentrations in the bivalves. The interspecific variations in the MeHg to THg ratio were largely controlled by the relative difference between the elimination rates of Hg(II) and MeHg. Stable isotope ({delta}{sup 13}C) analysis indicated that the five bivalve species had contrasting feeding niches, which may also affect the Hg accumulation. - Highlights: > Significant difference in Hg accumulation and MeHg:THg ratio in different bivalves. > THg concentrations in the bivalves were generally related to the efflux rates of Hg(II). > Elimination of Hg(II) and MeHg controlled the interspecific variation in MeHg:THg ratio. > MeHg and THg concentrations reflect the interaction of Hg biodynamics and food. - The species-specific body concentrations of MeHg and THg in bivalves reflect the complicated interaction between the biodynamics of Hg(II) and MeHg and the different food sources.

    Fish are a healthy source of protein, providing omega-3 (n-3) the fatty acids that reduce cholesterol levels, and reduce the incidence of heart disease and stroke. The purpose of the present study was to assess the concentration of some micronutrients and also fatty acids profile in muscles of the most consumed fish species from Cubatao coastal region. Cubatao carnivorous fish species analyzed were: Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada) and Menticirrhus americanus (Perna-de-Moca), and planktivorous species Sardinella braziliensis (Sardinha) and Mugil liza (Tainha). Micronutrients (Ca, Fe, K, Na, Se, Zn) in fish muscle were determined by means of instrumental neutron activation analysis (INAA). Fatty acids profiles in these muscle fish samples were performed by gas chromatography. Total saturated fatty acids ranged from 23.0% in M. ancylodon to 50.0% in M. liza. Total polyunsaturated fatty acid contents varied from 10.9% in M. liza 38.4% in S. braziliensis. These fish species presented different proportions of polyunsaturated fatty acids of the n-3 family and of the n-6 family. Regarding the n-6 family, M. furnieri showed the highest values (13.3%) and M. ancylodon, the lowest ones (4.1%). On the other hand, for the n-3 family, S. braziliensis presented the highest value (31.8%) and M. liza the lowest one (5.7%). Regarding micronutrients content, great concentration variations between individual of the same species and between different species were observed. From the nutritional point of view S. braziliensis is the best choice showing highest content of fatty acid n-3 family and micronutrient concentrations. (author)

    Perna viridis or green mussel is a potentially an important aquaculture product along the South Coast of Peninsular Malaysia especially Johor Straits. As the coastal population increases at tremendous rate, there was significant effect of land use changes on marine communities especially green mussel, as the heavy metals input to the coastal area also increase because of anthropogenic activities. Heavy metals content in the green mussel exceeded the Malaysian Food Regulations (1985) and EU Food Regulations (EC No: 1881/ 2006). Sampling was done at Johor Straits from Danga to Pendas coastal area for green mussel samples. This research introduces a catalytic oxidative technique for demetallisation in green mussel using edible oxidants such as peracetic acid (PAA) enhanced with alumina beads supported CuO, Fe 2 O 3 , and ZnO catalysts. The lethal dose of LD 50 to rats of PAA is 1540 mg kg -1 was verified by National Institute of Safety and Health, United State of America. The best calcination temperature for the catalysts was at 1000 degree Celsius as shown in the X-Ray Diffraction (XRD), Nitrogen Adsorption (BET surface area) and Field Emission Scanning Electron Microscopy (FESEM) analyses. The demetallisation process in green mussel was done successfully using only 100 mgL -1 PAA and catalyzed with Fe 2 O 3 / Al 2 O 3 for up to 90 % mercury (Hg) removal. Using PAA with only 1 hour of reaction time, at room temperature (30-35 degree Celsius), pH 5-6 and salinity of 25-28 ppt, 90 % lead (Pb) was removed from life mussel without catalyst. These findings have a great prospect for developing an efficient and practical method for post-harvesting heavy metals removal in green mussel. (author)

    This is the first study to use a multiple biomarker approach on the green-lipped mussel, Perna canaliculus to test its feasibility as a bioindicator of coastal metal contamination in New Zealand (NZ). Mussels were collected from six low intertidal sites varying in terms of anthropogenic impacts, within two regions (West Coast and Nelson) of the South Island of NZ. Trace elements, including arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn), were measured in the gills, digestive gland, foot and mantle, and in the surface sediments from where mussels were collected. Metal levels in the sediment were relatively low and there was only one site (Mapua, Nelson) where a metal (Ni) exceeded the Australian and New Zealand Interim Sediment Quality Guideline values. Metal levels in the digestive gland were generally higher than those from the other tissues. A variety of biomarkers were assessed to ascertain mussel health. Clearance rate, a physiological endpoint, correlated with metal level in the tissues, and along with scope for growth, was reduced in the most contaminated site. Metallothionein-like protein content and catalase activity in the digestive gland, and catalase activity and lipid peroxidation in the gill, were also correlated to metal accumulation. Although there were few regional differences, the sampling sites were clearly distinguishable based on the metal contamination profiles and biomarker responses. P. canaliculus appears to be a useful bioindicator species for coastal habitats subject to metal contamination. In this study tissue and whole organism responses provided insight into the biological stress responses of mussels to metal contaminants, indicating that such measurements could be a useful addition to biomonitoring programmes in NZ. - Highlights: • Multiple biomarker responses were measured in mussels from 6 sites. • Metal content of mussel tissues correlated with specific biomarker responses. • Clearance rate

    In view of the expressed need to study shellfish toxicity and elucidate the kinetics of saxitoxin in green mussels Perna viridis), uptake/depuration rates of saxitoxin were studied in Juag Lagoon, Sorsogon and Sorsogon Bay. Both areas experience recurring blooms of Pyrodinium bahamanse var compressum (PbC) making them excellent study sites. Two sampling stations were selected, to which, mussels were introduced. Algal cell density and mussel toxicity were measured by receptor binding assay (RBA) and high performance liquid chromatography (HPLC) from May to December 2007. During this period, two bloom events occurred, wherein, a decrease in cell density by two orders of magnitude (30,000 to 600 cells·1 +1 ) caused an order of magnitude decrease in toxicity (600 to 30 μg STX eq./100 g shellfish meat). A time lag between peaks of cell density and the corresponding toxicity was revealed. Vegetative cells were present throughout the sampling period, and a uniform horizontal and vertical distribution of cells was observed between the stations. Cell densities were significantly correlated with both RBA and HPLC estimates of STX content in mussels (Pearson r values of 0.7486 and 0.4325 for RBA and HPLC, respectively). In Sorsogon Bay, six sampling stations were also chosen, from which, water and mussels were being collected. Preliminary data showed that the cellular toxin content was primarily STX, making up to 90-100% of total toxin quantified. The average toxicity was estimated at 52.81fmol/cell. The effect of physiological factors to overall shellfish toxicity, though not directly characterized, may be deduced from these studies. (author)

    Full Text Available O autor assinala alguns aspectos interessantes observados em 17 pacientes portadores de distrofia muscular progressiva nos quais foi feita a avaliação da fôrça muscular pelos testes manuais. Os resultados foram reunidos em quadro que permitiu observar o acometimento muscular simétrico, afetando de preferência os músculos que movimentam as grandes articulações. Por outro lado, êstes déficits atingem de forma diversa os agonistas e antagonistas dentro da mesma unidade sinérgica, resultando daí as retrações músculo-tendíneas e as atitudes viciosas. São mais deficitários os músculos flexores da cabeça e tronco, os adutores e abaixadores da omoplata, os adutores e rotadores externos das coxas, os flexores e extensores das pernas e os flexores dorsais dos pés. Êste último fato contraria a opinião de autores, que admitem serem os músculos das panturrilhas (gastrocnêmios os mais afetados. O autor é contrário à opinião de que o diagnóstico de distrofia muscular progressiva implica na inutilidade de qualquer procedimento de reabilitação, sendo favorável ao emprêgo de programas de exercícios para evitar atitudes viciosas e para desenvolver as capacidades restantes. Considera o emprêgo de testes musculares manuais como método de escolha para a avaliação de incapacidades motoras, para acompanhar a evolução após ser instituído um programa de exercícios e quando se deseja estudar as respostas ao tratamento por drogas medicamentosas.

In addition, a lot of patients waiting for a heart transplant experience clinical deterioration, and other patients become ineligible to undergo this treatment due to their age or relevant comorbidities. Left ventricular assist devices have emerged as a valid therapeutic option for advanced heart failure. In recent years, we have seen significant advances not only in the technologies available, but also in patient selection, indications for use, and management after implantation. Consequently, there has been an increase in the number of implants and an improvement in the survival rate and quality of life for these patients. At the same time, there are new challenges on the horizon. Patient selection is a difficult process, based on clinical and imaging parameters and risk scores, and more data are needed to refine patient selection criteria and the timing of the implant. Left ventricular assist device-related complications are still a serious problem, causing adverse events and hospital readmissions. Continuous progress in the development of these implantable devices, such as a further reduction in size and hopefully the abolition of the external driveline, will probably make ventricular assist devices an option also for less advanced stages of heart failure. Here, we discuss the current indications for left ventricular assist device implantation, patient selection criteria, and the most frequent complications associated with these devices. Keywords

Multiple protocols are based on documented success in preventing impending complications. In this study, we present a case of a 70-year-old man who swallowed caustic soda in a suicide attempt, causing a development of strong esophageal and gastric necrosis with subsequent gastrectomy and digiunostomy. Initially, the recommended nutritional approach was via percutaneous endoscopic jejunostomy by a polymer and high-caloric formula, with an elevated content of soluble fiber. After 5 months, the medical team removed the percutaneous endoscopic jejunostomy and the patient switched from enteral to oral nutrition. In this step, it was decided to introduce two oral, high-caloric supplements: an energy supplement in powder, based on maltodextrin, immediately soluble in foods or in hot/cold drinks and a high-energy and protein drink, enriched with arginine, vitamin C, zinc, and antioxidants. Oral administration (per os was well tolerated by consuming homogenized food mixed in water. After 1 month, the patient was discharged from the hospital and was able to eat a regular meal.

    Full Text Available We describe a case report of disseminated cutaneous sporotrichosis as the initial presentation of AIDS in a 24-year-old HIV-positive male patient. He presented multiple ulcerated skin lesions distributed over the face, thorax, legs and arms. Biopsy of one of the cutaneous lesions was suggestive of sporotrichosis and culture isolated Sporothrix schenckii. Itraconazole was started and the lesions progressively resolved after 15 days of medication. The patient was discharged with this medication but he did not return for follow-up. He died three months later in another hospital. Therapy of sporotrichosis in HIV-infected patients remains unclear and the response to therapy is variable. Itraconazole is highly concentrated in the skin and is one of the options for treatment of disseminated sporotrichosis.Descrevemos um relato de caso de esporotricose cutânea disseminada como apresentação inicial de AIDS em um paciente masculino de 24 anos HIV positivo. Ele apresentava múltiplas lesões cutâneas ulceradas, distribuídas na face, tórax, pernas e braços. A biopsia de uma das lesões cutâneas foi sugestiva de esporotricose e a cultura revelou Sporothrix schenckii. Foi iniciado o tratamento com itraconazol e as lesões progressivamente involuiram depois de 15 dias de medicação. O paciente teve alta com tratamento ambulatorial, mas não retornou para seguimento. Ele morreu três meses depois em outro hospital. O tratamento da esporotricose em pacientes HIV positivos ainda não está estabelecido. Por sua boa penetração cutânea, o itraconazol é uma das melhores opções para formas disseminadas de esporotricose.

    Full Text Available Aquaculture business has been well established in Thailand for more than 40 years. The most recent data indicated a total production of 260 380 tons. Sixty-five percent of the total production came from coastal aquaculture, mainly tiger prawn (Penaeus monodon culture. Other important species for coastal aquaculture are banana prawn (P. merguensis, cockle (Anadara granosa, green mussel (Perna viridis, oyster (Crassostrea belcheri, Saccostrea commercialis, sea bass (Lates calcarifer and grouper (Epinephelus tauvina. Freshwater aquaculture, although produced only 35% of the annual production, provides major protein source for people in rural areas. Important freshwater species are Nile tilapia (Oreochromis niloticus, tawes (Puntius gonionotus, sepat Siam (Trichogasterpectoralis, walking catfish (Glorias spp., stripped catfish (Pangasius sutchi and giant freshwater prawn (Macrobrachium rosenbergii. Optimum aquacultural practises, namely stocking density, nutrition requirement and water quality have been obtained in most cultured species. But genetic approach has not been considered, thus resulting in deterioration in economic traits which might be due to excessive inbreeding (reviewed by Uraiwan 1989 and/or negative selection (Wongsangchan 1985. The history of researches on genetics in aquaculture in Thailand started in 1982 when the aquaculture genetic programme in form of a network has been established at the National Inland Fisheries Institute, Department of Fisheries. This programme was supported by the International Development Research Centre (IDRC, Canada in cooperation with Dalhousie University, Canada (Uraiwan 1989.

    Full Text Available O culturismo é um esporte que enfatiza a aparência física, a configuração e o formato corporais, buscando assim a excelência estética. A cineantropometria é uma ferramenta fundamental para guiar o curso do treinamento no culturismo. No entanto, existe escassez na produção de trabalhos científicos para essa população. O objetivo deste trabalho é descrever a composição corporal, o somatotipo e a proporcionalidade de 23 culturistas finalistas do Campeonato Brasileiro de Culturismo do ano de 2000. Os atletas foram avaliados momentos antes da competição e as seguintes variáveis determinadas: peso total, estatura, nove dobras cutâneas (triceptal, subescapular, biceptal, peitoral, axilar média, supra-ilíaca, abdominal, medial da coxa e medial da perna, dois perímetros musculares (braço fletido e perna e três diâmetros ósseos (umeral, biestiloidal e femoral, conforme a metodologia proposta pela International Society for the Advancement of Kineanthropometry (ISAK. Os atletas apresentaram idades entre 20 e 56 anos e peso corporal entre 57,4kg e 105,8kg. O somatório das nove dobras cutâneas (S9DC variou entre 38,4mm e 70,2mm. O somatotipo encontrado foi de 1,8-8,1-0,7, classificado como mesomorfo balanceado. O percentual médio de gordura foi de 9,65%, usando o protocolo de Faulkner, proposto pelo Grupo Brasileiro de Cineantropometria. O peso de gordura encontrado foi de 7,29kg. Quando comparados ao Phantom, os atletas estudados apresentaram maiores: peso corporal (Z = +1,66, perímetro de braço (Z = +5,26 e perímetro de perna (Z = +1,91. Conclui-se que os culturistas brasileiros de elite estudados apresentam baixo percentual de gordura e grande peso muscular, quando comparados com o modelo de Ross e Wilson (1974, sendo a sua estrutura corporal semelhante à dos culturistas da elite internacional.El fisicoculturismo es un deporte que enfatiza la apariencia física, la configuración y el formato corporal, buscando así la

Os estágios de maturação genital de Tanner (G-5 foram utilizados para subdividir a amostra nas três categorias sugeridas por Nicoletti: pré-puberal (G1, puberal inicial (G2-3 e puberal avançada (G4-5. Foi utilizada a análise discriminante passo a passa (stepwise, tendo como critério de seleção o aumento da porcentagem de indivíduos classificados corretamente. Foram utilizadas 35 variáveis, das quais foram selecionadas: estatura, dobras cutâneas tríceps e subescapular, perímetros da perna e do braço relaxado, massa corporal, e os comprimentos do antebraço e coxa. Essa análise gerou um novo grupo composto por 87% do grupo original. Duas funções lineares discriminantes (LDF1 e LDF2 emergiram: LDF1 diferenciou os indivíduos pré-púberes dos púberes avançados, tendo incluído as variáveis: estatura, massa corporal, comprimento do antebraço e coxa, e os perímetros do braço e da perna. A segunda função, a LDF2, diferenciou os indivíduos no início da puberdade dos demais grupos. O segundo grupo de variáveis incluiu: a dobra cutânea do tríceps e o perímetro da perna. Os intervalos de confiança demonstraram que duas variáveis de tamanho, duas de gordura subcutânea, duas de robustez esquelética e duas de muscularidade relativa são suficientes para guiar os técnicos, na classificação de jovens nadadores, em categorias que melhor aproximem do seu estágio maturacional. Somente as dobras cutâneas do tríceps e subescapular mostraram superposição dos intervalos de confiança nas três categorias.

    Full Text Available A proposta deste estudo foi examinar o tempo de resposta eletromiográfica dos músculos fibulares, na inversão repentina do pé, em tornozelos com presença de lesão e saudáveis. Três grupos foram testados, um de atletas normais (grupo 1, um de atletas com história recente de entorse de tornozelo (grupo 2 e o outro de não atletas com história recente de entorse de tornozelo (grupo 3. Para cada sujeito dos três grupos, ambos os tornozelos foram testados. Os sujeitos que sofreram entorse de tornozelo (grupos 2 e 3 não apresentavam sintomas de lesão durante os últimos dois meses antes do teste. Uma plataforma capaz de produzir uma inversão repentina lateral de 20° do tornozelo no plano frontal simulava um evento de entorse de tornozelo. Eletrodos de eletromiografia de superfície foram colocados na pele sobre os músculos fibulares. Os tempos de resposta eletromiográfica dos músculos fibulares foram obtidos e comparados entre os grupos. Para o grupo 1, a média dos tempos de resposta eletromiográfica foi de 71ms para a perna direita e 69ms para a perna esquerda. Para o grupo 2, a média dos tempos de resposta eletromiográfica foi de 72ms para o tornozelo sem lesão e 74ms para o tornozelo com a lesão. Para o grupo 3, a média dos tempos de resposta eletromiográfica foi de 72ms para o tornozelo sem lesão e 73ms para o tornozelo com a lesão. Os resultados indicaram que não houve diferença estatisticamente significante entre as pernas direita e esquerda no grupo 1 e entre os tornozelos sem lesão e com lesão dos grupos 2 e 3 para os músculos fibulares. Os achados do presente estudo sugerem que a resposta eletromiográfica dos músculos fibulares, durante o deslocamento angular repentino do tornozelo, não foi influenciada pela entorse de tornozelo.La propuesta de este estudio era examinar el tiempo de la respuesta electromiográfica de los musculos fibulares, en el esguince agudo del pie, en los tobillos con la presencia de l

Utilizaram-se 40 animais (20 machos e 20 fêmeas, desmamados aos 60 dias e alimentados, à vontade, com uma ração com 16,46% de PB e 67,63% de NDT. Foram divididos em quatro grupos de machos (G1M, G2M, G3M e G4M, sacrificados, respectivamente, com os pesos supracitados, e, da mesma forma, quatro grupos de fêmeas (G1F, G2F, G3F e G4F. Determinaram-se as medidas da carcaça e, de forma subjetiva, a condição corporal, o grau de conformação e o grau de gordura de cobertura. Calcularam-se os índices de compacidade da carcaça e da perna. Foram registrados os pesos e as porcentagens de sete cortes da meia carcaça, bem como as porcentagens de osso, músculo e tecido adiposo, avaliadas por meio de dissecção do lombo. A espessura da gordura de cobertura foi determinada na região lombar. O estudo morfométrico confirmou maior alongamento ósseo dos machos. De maneira geral, as carcaças apresentaram-se com bom acabamento, segundo os índices de compacidade verificados. Os cortes das carcaças das fêmeas foram mais pesados que os dos machos (exceto para o peso de 28 kg ao abate, principalmente em função dos maiores teores de gordura. Destaca-se a representabilidade dos pesos da pele e do conteúdo gastrintestinal na determinação do rendimento da carcaça. Pelos resultados obtidos, recomenda-se 28 kg como peso referência para sacrifício.

Porém, estudos recentes contestam essa abordagem terapêutica, enfatizando que a mobilização precoce propicia resultados clínicos favoráveis. O objetivo deste estudo foi pesquisar em literatura científica, principalmente ensaios clínicos controlados, sobre a mobilização precoce de pacientes portadores de trombose venosa profunda de membros inferiores na fase aguda. Utilizou-se como estratégia de pesquisa o site PubMed para a busca de estudos relacionados à mobilização precoce, deambulação e trombose venosa profunda na fase aguda. Os artigos consultados abrangeram o período de 1992 a 2007. Em todos os estudos, a mobilização precoce esteve associada à heparina de baixo peso molecular e a terapia de compressão. Estudos avaliados nesta revisão têm demonstrado os benefícios na redução da dor e edema, com melhora da qualidade de vida, pela estratégia terapêutica de mobilização precoce em combinação com anticoagulação e compressão da perna na trombose venosa profunda, sem que ocorra maior risco de desfechos relevantes, como embolia pulmonar e morte.Conventional treatment of deep venous thrombosis in the acute phase includes bed rest. However, recent studies have challenged such therapeutic approach, emphasizing that early mobilization provides favorable clinical outcomes. This study aimed at finding qualified scientific studies, especially controlled clinical trials, on early mobilization of patients with acute deep venous thrombosis of the lower limbs. PubMed was used to search for articles related to early mobilization, ambulation and acute deep venous thrombosis. Articles covered the period from 1992 to 2007. In all studies, early mobilization was associated with low molecular weight heparin and compression therapy. Studies evaluated in this review showed benefits in reducing pain and edema, with improvement in

    Full Text Available Os níveis de hemoglobina fetal (HbF foram analisados em 47 pacientes com anemia falciforme, residentes em Fortaleza, capital do Ceará, com a finalidade de fornecer informações sobre a influência da HbF no prognóstico desta doença. A determinação dos valores hematológicos foi realizada em contador automático de células sanguíneas (modelo Sysmex KX-21N, Roche e os níveis de HbF foram determinados pela técnica da desnaturação alcalina. Dentre os resultados foi demonstrada uma tendência de menor número de pacientes com crises vaso-oclusivas (p=0,0405 e úlceras de perna (p=0,0076 com o aumento dos níveis de HbF. Não houve diferença estatisticamente significativa na comparação entre os níveis de HbF e os valores de hemácias, hemoglobina, hematócrito, leucócitos e plaquetas. Os resultados demonstram que os níveis de hemoglobina fetal podem ser utilizados como fator prognóstico nos pacientes com anemia falciforme, no entanto não deve ser a única ferramenta diagnóstica para prever o quadro clínico destes pacientes.The fetal hemoglobin (HbF levels of 47 patients with sickle cell anemia living in Fortaleza, Brazil were analyzed to provide information on the influence of HbF on the prognosis of this disease. Measurement of hematological variables was achieved using a Sysmex KX-21N cell counter ( Roche and the levels of HbF were determined by the alkali denaturation technique. With increased levels of HbF, there was a trend that fewer patients had painful episodes (p = 0.0405 and leg ulcers (p = 0.0076. There were no statistically significant differences between the levels of HbF and the concentrations of red blood cells, hemoglobin, hematocrit, leukocytes and platelets. The results show that levels of fetal hemoglobin can be used as a prognostic factor in patients with sickle cell anemia however they should not be the only diagnostic tool to predict the clinical status of these patients.

A etiologia é multifactorial, sendo a obstrução da via aérea superior o factor desencadeante principal. O esforço inspiratório contra a glote encerrada causa pressões intratorácicas muito negativas, que se transmitem ao interstício pul-monar, condicionando uma transudação de fluidos a partir dos vasos capilares pulmonares1−5. Relatamos um caso de edema agudo do pulmão pós-extubação num doente de quinze anos, operado no serviço de urgência por amputação traumática da perna esquer-da.

    Aside from their nutritional importance, fish are considered one of the most important bio indicators in aquatic systems for the estimation of pollution levels by toxic metals. This is so, since fish can bio accumulate these elements and they occupy different trophic levels and present different sizes and age. The purpose of the present study was to contribute with important data for the knowledge of nutritional and toxic constituents in muscles of the most consumed fish species from two coastal regions, Cananeia and Cubatao. Cananeia fish species analyzed were: Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Centropomus undecimalis (Robalo peba) and Mugil platanus (Tainha). From Cubatao, Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de moca), Sardella braziliensis (Sardinha) and Mugil liza (Tainha). For this study, analytical methodologies were developed and validated, regarding precision and accuracy, by means of certified reference materials. Micronutrients (Ca, Fe, K, Na, Se and Zn) and some trace elements (As, Br, Co, Cr, Rb) in fish muscle were determined by means of neutron activation analysis (NAA). Cold Vapor Atomic Absorption Spectrometry (CV AAS) was used for total Hg determination and Electrothermal Atomic Absorption Spectrometry (ET AAS) for Cd and Pb determinations. Proximate composition determinations according to AOAC methodologies and fatty acids profiles by gas chromatography were done in these muscle fish samples. Regarding fatty acids profile from the ω-6 family, Tainha species pool presented the highest values (8.9%) and Pescada species pool the lowest ones (4.4%) for Cananeia species. Fatty acids from the ω-3 family, Sardinha pool species presented the highest values (31.8%) for all species analyzed. Regarding micronutrients content great concentration variations between individual of the same species and between different species were observed. Discriminate analysis was used

    Full Text Available Percebe-se que o padrão produtivo na agricultura de um país determina mudanças significativas na saúde social e ambiental, refletindo-se na qualidade de vida dos agricultores. Objetivou-se caracterizar o processo de trabalho da Agricultura Orgânica Familiar (AOF e sua relação com a qualidade de vida dos trabalhadores. A população pesquisada foi composta de 29 agricultores, com idade média de 50 anos, e a composição familiar se constituiu, em média, de 5 a 8 moradores por domicílio. O tempo médio de trabalho na agricultura é de 39 anos e na agricultura familiar orgânica é de 16 anos. Quanto à renda mensal, verificou-se que a maioria dos trabalhadores pesquisados ganha um valor muito abaixo da média de renda desses trabalhadores. Todos contavam com abastecimento de energia elétrica e de água. No total de 8 propriedades, em 5 não existia coleta de lixo sendo este queimado. Referiram-se ao aparecimento de alguns sintomas como câimbras e fadigas nas pernas. Em relação à qualidade de vida, o domínio psicológico contribuiu positivamente para a qualidade de vida com média e desvio (17,83±12,78 e o domínio ambiente contribuiu negativamente para a qualidade de vida desse grupo (9,00±6,82. Concluiu-se que os trabalhadores têm percepção positiva acerca de sua qualidade de vida e há presença significativa do trabalho coletivo no curso da ação. Os agricultores apresentam dificuldades definidas com problemas de baixa renda devido à pouca venda da produção.

Foram utilizados 48 cordeiros machos não castrados, que foram divididos em três grupos: restrição pré-natal, restrição pós-natal e nenhum tipo de restrição (grupo controle. Os animais foram sorteados aleatoriamente para serem abatidos nas faixas de 15, 25, 35 e 45 kg de peso vivo, quatro animais de cada manejo alimentar. No abate, os animais foram suspensos pelos membros posteriores e insensibilizados mecanicamente. Posteriormente, procedeu-se à secção da artéria carótida e veias jugulares, com coleta e pesagem do sangue. Depois da determinação do peso de carcaça fria (PCF, foram feitos os seguintes cortes na carcaça: pescoço, costeletas, paletas, costelas/fraldas, lombos, pernas, braços anteriores e posteriores. Após a pesagem dos cortes, foram calculadas as porcentagens em relação ao PCF. As restrições alimentares pré e pós-natal apresentaram efeitos no crescimento relativo dos cortes comerciais da carcaça, em relação à carcaça fria, tanto entre os diferentes manejos alimentares como entre os pesos de abate, comprovando a importância da correta suplementação das ovelhas no terço final de gestação, principalmente quando gestantes de gêmeos, como na fase posterior ao nascimento até a idade ou peso de abate.

    Full Text Available As epidermólises bolhosas são dermatoses bolhosas congênitas que levam à formação de bolhas espontaneamente ou após trauma. São reconhecidos três grupos de da doença, de acordo com o segundo consenso internacional: simples, juncional e distrófica. Nas formas distróficas, o defeito genético deve-se à mutação no gene COL7A1, responsável pela codificação do colágeno VII, principal constituinte das fibrilas de ancoragem, que participam na aderência da lâmina densa à derme. Os autores relatam o caso de paciente do sexo feminino, de 15 anos, apresentando ulcerações nas pernas, bolhas serosas e lesões atrófico-acastanhadas nos braços e tronco. Foram observadas distrofias ungueais e alterações dentárias, iniciadas a partir do nascimento. O exame histopatológico da bolha revelou quadro compatével com epidermólise bolhosa, que, associado aos dados clínicos, permitiram a classificação do caso na forma distrófica recessiva mitis.Epidermolysis bullosa are congenital bullous dermatoses that lead to spontaneous or post-traumatic formation of blisters. There are three recognized disease groups, according to the second international consensus: simplex, junctional and dystrophic. The genetic defect of the dystrophic forms is due to a mutation in the COL7A1 gene, which is responsible for codifying collagen VII, the main representative of anchoring fibrils, which participate in the adherence of the "lamina densa" to the dermis. The authors describe a case of a 15 year-old female patient who presented ulcers on her legs, serous blisters and atrophic scars on her arms and body. Dystrophic ungual and dental abnormalities had also been observed since her birth. Blister histopathological examination was compatible with epidermolysis bullosa, which, in association with clinical data, allowed the classification of recessive distrophic epidermolysis bullosa.

    Full Text Available DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n4p411   Assimetrias na pedalada quantificadas durante o ciclismo estacionário, em que a postura do ciclista e a intensidade não mudam significativamente, podem não reproduzir situações de treino e competições em que os ciclistas experimentam diferentes intensidades e optam por mudar a postura no selim para otimização da potência. Estudos prévios mostraram assimetrias no torque e potência de ciclistas. Não é claro se mudanças na posição do selim e intensidade afetam essas assimetrias. O objetivo do presente estudo foi determinar as assimetrias na pedalada durante o ciclismo em diferentes alturas de selim e diferentes intensidades de esforço. Doze ciclistas competitivos realizaram um teste incremental máximo, um teste de carga constante (domínio severo e um teste de Wingate. Os testes de carga constante e Wingate foram repetidos usando três alturas de selim (referência e 2,5% abaixo ou acima da referência, que foi medida pela distância da sínfise púbica até o solo. O torque gerado no pedivela foi medido durante todo o ciclo de pedalada. Assimetrias (maior torque na perna preferida foram encontradas em todas as alturas de selim (p<0,001 em ambas as intensidades. O índice de assimetria foi similar em todas as alturas de selim (p<0,05 em ambas as intensidades. Os resultados sugerem que ciclistas assimétricos apresentam um padrão consistente independente de pequenas mudanças na posição do selim ou intensidade do exercício. Como implicação prática, ciclistas produzindo torque assimétrico podem estar adaptados a esta condição e sendo continuamente expostos a esforços e sobrecargas assimétricas nos membros inferiores.

    Full Text Available Com o objetivo de estimar a perda de calor sensível em cordeiros em confinamento e quantificar a energia metabolizável utilizada para manutenção da temperatura corporal, sob estresse térmico pelo frio, foram utilizados 24 cordeiros cruzados e não castrados, (média de 120 dias de idade, 26,3 kgde peso vivo e sob dieta com 2,94 kcal animal-1 dia de energia metabolizável. Destes, selecionou-se aleatoriamente seis animais, que foram referência para coleta dos seguintes parâmetros do ambiente de alojamento: temperatura do ar mínima e máxima, velocidade do ar, umidade relativa do ar e luminosidade. Para estimar o gasto energético foram consideradas as temperaturas superficiais médias das regiões de cabeça, orelhas e pernas, obtidas com o auxilio da câmara termográfica infravermelho e respectivo software. Durante o período foi verificado que a temperatura ambiente ficou abaixo da zona de conforto térmico e que a temperatura superficial corporal média dos cordeiros foi de 11,48 ± 0,92 °C, indicando que houve uma interação entre os parâmetros climáticos avaliados, promovendo o resfriamento do ambiente e influenciando na redução da temperatura superficial. A dissipação total de calor sensível por animal nas partes analisadas foi de 39,18 W, o que corresponde ao consumo de 0,388 kcal 12 h-1. Constatou-se que, 26,4% da energia metabolizável diária ingerida pelos cordeiros, nos dias de temperatura abaixo da zona de conforto térmico, foi utilizada para termogênese. Contudo, foi verificado que, por estarem abaixo da zona de conforto térmico, os cordeiros dissiparam o calor sensível por convecção e radiação, utilizando parte da energia metabolizável da dieta para manter a temperatura corporal, situação que pode acarretar perdas econômicas para a produção. Palavras-chave: energia metabolizável, ovinos, termografia.

    Chlorination is the most commonly used method of biofouling control in cooling water systems of coastal power stations. In the present study, we report results of extensive sampling in different sections of the cooling water system of an operating power station undertaken during three consecutive maintenance shutdowns. The power plant employed continuous low level chlorination (0.2 ± 0.1 mg L -1 TRO) with twice-a-week booster dosing (0.4 ± 0.1 mg L-1 TRO for 8 hours). In addition, the process seawater heat exchangers received supplementary dosing of bromide treatment (0.2 ± 0.1 mg L -1 TRO for 1 hour in every 8 h shift). Biofouling samples were collected from the cooling water conduits, heat exchanger water boxes, pipelines, heated discharge conduits and outfall section during the annual maintenance shutdown of the plant in the years 2007, 2008 and 2009. Simultaneous monitoring of biofouling on test coupons in coastal waters enabled direct comparison of fouling situation on test panels and that in the cooling system. The data showed significant reduction in biofouling inside the cooling circuit as compared to the coastal waters. However, significant amount of fouling was still evident at several places, indicating inadequacy of the biocide treatment regime. The maximum load of 31.3 kg m 2 y -1 was observed in the conduits leading to the process seawater heat exchangers (PSW-HX) and the minimum of 1.3 kg m 2 y -1 was observed in the outfall section. Fouling loads of 12.2 - 14.7 kg m 2 y -1 were observed in the concrete conduits feeding the main condensers. Bromide treatment ahead of the PSW-HX could marginally reduce the fouling load in the downstream section of the dosing point; the HX inlets still showed good biofouling. Species diversity across the cooling water system showed the pre-condenser section to be dominated by green mussels (Perna viridis), pearl oysters (Pinctada sp.) and edible oysters (Crassostrea sp.), whereas the post-condenser section and heat

We report the case of a 71-year-old female who presented with an erythematous tender node which had appeared one month previously, progressing to ulceration and yellowish exudation. No abdominal symptoms. Biopsy revealed fat necrosis and vacuolated macrophages represented by amorphous amphophilic areas. Laboratory examination and CT scan revealed chronic pancreatitis. It is assumed that release of pancreatic enzymes such as trypsin may enhance the permeability of the microcirculation leading to lipase and amylase causing the subcutaneous fat necrosis observed in the lesions.

A dor e desconforto foi identificada através de uma figura do corpo humano onde eles referiam estes sintomas. Resultados: a maioria dos industriários apresentam excesso de peso (56,4% e bom percentual de gordura (49,2%, porém possuem resultados inadequados de flexibilidade de ombro (71,0% e parte posterior de tronco e pernas (64,6% e presença de dor e desconforto em ombros (50% e costas (26,6%. Ao relacionar a flexibilidade com a presença de dor e desconforto, percebe-se que as variáveis não se relacionam diretamente. Considerações finais: o perfil dos trabalhadores da indústria se caracteriza por excesso de peso, baixa aptidão na flexibilidade e presença de dor e desconforto. Sobre a dor e desconforto observa-se uma tendência de associação entre níveis de flexibilidade inadequada e a presença destes sintomas.

    Full Text Available Introdução: O grande índice de lesões do ligamento cruzado anterior sem envolver contato em mulheres é motivo de curiosidade entre os cientistas, pois avaliações de aterrissagem podem sugerir a predisposição ao risco dessa lesão. Neste sentido, vários protocolos de treinamento foram utilizados como intervenção e obtiveram resultados diversificados na alteração desse fator de risco. Objetivo: O objetivo deste projeto foi avaliar as possíveis alterações de rotação do joelho na aterrissagem unipodal após a intervenção de um programa de treinamento neuromuscular. Métodos: Participaram do estudo 18 mulheres com idade entre 18 e 51 anos, que foram distribuídas em dois grupos: grupo de treinamento neuromuscular de oito semanas (GTN (n = 11 e grupo controle (GC (n = 7. Além disso, não apresentavam lesão musculoesquelética ou dores nos membros inferiores. Cada participante realizou cinco aterrissagens unipodais válidas de uma plataforma de 40 cm de altura. O processo de captura de movimento foi realizado com 12 câmeras infravermelho do sistema OptiTrack(tm para obter as coordenadas tridimensionais de marcadores fixados nos pontos anatômicos de interesse. Os sistemas de coordenadas locais da coxa e da perna foram definidos por meio dos respectivos marcadores fixados nos pontos anatômicos. Dessa forma, foram calculados os ângulos de rotação do joelho nos planos sagital, frontal e transverso através das sequências dos ângulos de Euler e as velocidades angulares através das formulações dos quatérnions. Resultados: Os resultados mostraram que houve um aumento na velocidade de rotação do joelho após o treinamento neuromuscular. Conclusão: Conclui-se que o treinamento neuromuscular resultou em maior velocidade de rotação no joelho nos 40 milissegundos que sucedem a aterrissagem unipodal.

    Aside from their nutritional importance, fish are considered one of the most important bio indicators in aquatic systems for the estimation of pollution levels by toxic metals. This is so, since fish can bio accumulate these elements and they occupy different trophic levels and present different sizes and age. The purpose of the present study was to contribute with important data for the knowledge of nutritional and toxic constituents in muscles of the most consumed fish species from two coastal regions, Cananeia and Cubatao. Cananeia fish species analyzed were: Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Centropomus undecimalis (Robalo peba) and Mugil platanus (Tainha). From Cubatao, Micropogonias furnieri (Corvina), Macrodon ancylodon (Pescada), Menticirrhus americanus (Perna de moca), Sardella braziliensis (Sardinha) and Mugil liza (Tainha). For this study, analytical methodologies were developed and validated, regarding precision and accuracy, by means of certified reference materials. Micronutrients (Ca, Fe, K, Na, Se and Zn) and some trace elements (As, Br, Co, Cr, Rb) in fish muscle were determined by means of neutron activation analysis (NAA). Cold Vapor Atomic Absorption Spectrometry (CV AAS) was used for total Hg determination and Electrothermal Atomic Absorption Spectrometry (ET AAS) for Cd and Pb determinations. Proximate composition determinations according to AOAC methodologies and fatty acids profiles by gas chromatography were done in these muscle fish samples. Regarding fatty acids profile from the {omega}-6 family, Tainha species pool presented the highest values (8.9%) and Pescada species pool the lowest ones (4.4%) for Cananeia species. Fatty acids from the {omega}-3 family, Sardinha pool species presented the highest values (31.8%) for all species analyzed. Regarding micronutrients content great concentration variations between individual of the same species and between different species were observed. Discriminate analysis

The association among sarcopenia with adiposity and metabolic markers has rarely been studied in the elderly population, with controversial results. The aim of this study is to evaluate this relationship in older subjects.Methods: A cross-sectional study was conducted in 290 elderly patients, focusing on the possible association between muscle mass loss, assessed by relative skeletal muscle mass (RSMM, and an adipo-metabolic profile (AMP defined by adiposity and metabolic biochemical markers. Measurements of body composition were assessed by dual energy X-ray absorptiometry. Biochemical parameters, such as albumin, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total cholesterol, triglycerides, C-reactive protein, and homocysteine and its related markers (folate and vitamin B12 were measured. Using canonical correlation analysis and structural equation modeling, an individual score of AMP was created and correlated with RSMM.Results: The AMP–RSMM correlation was equal to +0.642 (95% confidence interval, +0.512 to +0.773; P<0.001. Hence, a negative association between sarcopenia severity and adiposity/metabolic biochemical markers was highlighted.Conclusion: This study contained a novel way to examine the relationship between the variables of interest based on a composite index of adiposity and metabolic conditions.

Método: a amostra foi composta por 30 mulheres saudáveis com idade entre 18 e 25 anos, com ciclo menstrual regular e que não utilizavam anticoncepcional oral ou injetável no período do estudo, na cidade de Fortaleza-CE, Brasil. A adiposidade corporal foi predita a partir da quantificação do somatório de seis dobras cutâneas (S ADIP. Essa variável foi utilizada no cálculo do escore de proporcionalidade (Z ADIP, subsidiando a realização do cálculo da massa adiposa absoluta (M ADIP. Resultados: a média de idade foi de 21,8 anos e de estatura 162,2 cm. Considerando a disposição de adiposidade por dobra cutânea, durante as três fases do ciclo menstrual, as dobras tricipital, subescapular, abdominal e espinal apresentaram maior média na fase lútea (14,8; 11,9; 19,5; 10,6 respectivamente; a dobra coxa apresentou valores de médias estatisticamente semelhantes nas fases folicular e ovulatória (20,1 e a dobra perna apresentou maior média na fase folicular (13,4. Analisando a prevalência do maior somatório de dobras cutâneas e a relação com a maior quantificação de massa adiposa absoluta, constatou-se que a fase folicular apresentou a maior média de somatório de dobras (89,6 e de massa adiposa (19,3. Considerações finais: os dados encontrados revelam que, durante as fases do ciclo menstrual, não há diferença significativa no somatório das dobras cutâneas e de massa adiposa absoluta. Este fato sugere que as alterações hormonais ocorridas durante o ciclo não estão diretamente associadas com o fator de variabilidade da adiposidade corporal.

    Full Text Available INTRODUÇÃO: Artes marciais como Karate e Jiu-Jitsu têm uma origem comum, porém apresentam biomecânica de movimento distintas. O Karate Shotokan tem como principal característica os golpes de impacto, já o Jiu-Jitsu utiliza projeções, estrangulamentos, torções e imobilizações. Estas diferenças poderiam promover diferentes locais de lesão. OBJETIVO: Verificar a frequência de lesões no Karate e no Jiu-Jitsu e comparar estas lesões entre os dois grupos estudados. MÉTODOS: Avaliou-se transversalmente, através de questionário aberto/fechado, 94 atletas dos três níveis de competição: internacional, nacional e estadual. Dados sobre idade de início e tempo de treino também foram avaliados. Para a comparação entre os grupos utilizou-se o teste t de student e o teste do Qui-quadrado. As diferenças foram consideradas significativas quando p < 0,05. RESULTADOS: 148 lesões foram relatadas em uma amostra de 53 Karatecas e 160 lesões em 41 atletas de Jiu-Jitsu. O local de maior incidência de lesão no Karate foram as mãos e dedos (15,5% e no Jiu-Jitsu foi o joelho (16,3%. Os locais que apresentaram diferenças significativas entre os dois grupos foram: perna (0,042, boca e dentes (0,028, pescoço (0,038, ombro (0,000, cotovelo (0,001, joelho (0,000, tornozelo (0,015, orelha (0,000. CONCLUSÃO: Karate e Jiu-Jitsu apresentam diferenças quanto à frequência e incidência de locais de lesão. Estes achados contribuem para a elaboração de condutas preventivas e terapêuticas específicas a cada esporte.

    Full Text Available A úlcera de Buruli, uma doença infecciosa causada pela Mycobacterium ulcerans (M. ulcerans,é a terceira micobacteriose em ocorrência, após a hanseníase e a tuberculose. Essa micobacteriose atípica tem sido relatada em mais de 30 países, principalmente, nos que têm climas tropicais e subtropicais, mas a sua epidemiologia permanece obscura. Recentemente, os primeiros casos autóctones do Brasil foram relatados, fazendo com que dermatologistas brasileiros estejam atentos a esse diagnóstico. O quadro clínico varia: nódulos, áreas de edema, placas, mas a manifestação mais típica é uma grande úlcera, que ocorre, em geral, nas pernas ou nos braços. Apesar do amplo conhecimento quanto ao seu quadro clínico em países endêmicos, nas outras áreas, esse diagnóstico pode passar despercebido. Assim, médicos devem ser orientados quanto à úlcera de Buruli, pois o diagnóstico precoce, o tratamento específico e a introdução de cuidados na prevenção de incapacidades são essenciais para uma boa evolução.Buruli ulcer, an infectious disease caused by Mycobacterium ulcerans, is the third most prevalent mycobacteriosis, after tuberculosis and leprosy. This atypical mycobacteriosis has been reported in over 30 countries, mainly those with tropical and subtropical climates, but its epidemiology remains unclear. The first autochthonous cases of infection in Brazil have recently been described, making this diagnosis important for Brazilian dermatologists. Clinical manifestations vary from nodules, areas of edema, and plaques, but the most typical presentation is a large ulcer, usually in the limbs. Despite considerable knowledge about its clinical manifestations in some endemic countries, in other areas the diagnosis may be overlooked. Therefore, physicians should be educated about Buruli ulcer, since early diagnosis and treatment, including measures to prevent disability, are essential for a good outcome.

    Full Text Available Desde o momento em que Maximiliano Salinas publicou sua Historia del pueblo de Dios en Chile em 1987, ele inova em termos de pesquisa sobre temas que tradicionalmente caem fora do campo de visao do historiador cristao. A inovaçao de 1987 visava aspectos heurísticos, pois mencionado livro partia de folhetos populares, cânticos, benditos, refroes, poesias. Com seu mais novo ensaio, Gracias a Dios que comí, Maximiliano Salinas completa o trabalho heurístico anterior por importantes inovaçoes no campo hermenéutico. O ensaio apresenta o painel de um cristianismo pouco analisado na literatura mas intensamente praticado por descendentes de indígenas, africanos mas também portugueses (fértil fronteira com o Islam. Ele insiste na positividade das culturas que encaram a Deus como fonte da subsistencia, quem nos dá o pao para comer, as pernas para dançar, o ânimo para transformar o trabalho em festa. Ele fala de um Deus cristao dionisíaco. Trata-se de uma inusitada memória crista, e apagada nos textos ortodoxos do cristianismo histórico relegada ao mundo dos textos apócrifos, mas que encontra fortes concordâncias nas culturas azteca, quechua e mapuche onde se vive o trabalho como festa, onde Deus tem maos (para trabalhar e entranhas (para compartir, onde a comida é uma hierofania (as comidas sagradas e o paraíso um deleite culinário. Aí Deus nao é mais o 'preceptor absoluto' mas o 'poeta' (no sentido original: quem faz, quem executa a obra.

    Full Text Available Os contos e as lendas do folclore brasileiro apresentam uma riqueza ímpar tanto de personagens quanto de temas e permitem que trechos e traços da história nacional sejam trazidos em suas singularidades e universalidades. A lenda do “Saci-Pererê”, representada por um menino negro de uma perna só e que fuma um cachimbo, nasce da mestiçagem brasileira, da fusão de etnias, culturas, conhecimentos, crenças e valores em que uma geografia se impõe (CASCUDO, 1954; MEIRELES, 1983; ANDRADE, 1976. A ideia da liberdade é representada por esse personagem que aparece e desaparece com o vento, fazendo peraltices por meio dos poderes mágicos de seu gorro vermelho. Esse trabalho tem como objetivo narrar uma experiência pedagógica realizada com crianças de 02 a 06 anos de idade, em uma escola pública do município de Campinas-SP, a partir de procedimentos de ensino realizados com contos e lendas do folclore. Diversos personagens, como o “Saci-Pererê”, a “Cuca” e o “Boitatá”, ganharam vida por meio da imaginação, aparecendo em nosso cotidiano e instigando diversas brincadeiras com as crianças, como as de aparecer e desaparecer com o vento, saltitar, fazer mágicas e misturar os brinquedos, por exemplo. Concluímos que, ao aproximarmos as crianças das manifestações folclóricas presentes em nosso dia-a-dia, valorizamos outros conhecimentos, abrindo caminhos diferentes para curiosidades e experiências infantis (BOSI, 1992; KISHIMOTO, 1998. Como resultado desse trabalho, percebemos o enriquecimento do repertório das brincadeiras infantis e o interesse e a participação da comunidade com suas vivências, lembranças e narrativas que constituem memórias da infância.

    Full Text Available A new species of Temnocephala Blanchard, 1849 is described from southern Brazil, ectosymbiont on giant water bugs (aquatic hemipterans, Belostoma spp. from the greater Porto Alegre, State of Rio Grande do Sul. Some hemipterans examined were positive for this species of Temnocephala and carried bunches of eggs between the first two pairs of legs and between the first pair of legs and the rostrum, as well as adult and young specimens. The adults were darkly pigmented (greenish-brown, mimetizing the color of the hemipteran hosts. The new species is similar to Temnocephala decarloi Moretto, 1978, from Argentina, the only other species of Temnocephala from belostomatid hemipterans known to date, by having an extra long and curved cirrus, but differs by having the distal portion of the introvert not bent as a 'full-bent' smoking pipe-like, as the author depicted originally for T. decarloi.Uma nova espécie de Temnocephala Blanchard, 1849 é descrita para o sul do Brasil, ectosimbionte sobre baratas-d'água (hemípteros aquáticos, Belostoma spp. da região metropolitana de Porto Alegre, Estado do Rio Grande do Sul. Vários hemípteros examinados estavam positivos para esta espécie do gênero Temnocephala, inclusive com posturas sempre localizadas na face ventral entre os dois primeiros pares de apêndices locomotores, e entre o primeiro par de pernas e o rostro. Espécimes adultos e jovens de tamanhos variados também foram sempre encontrados na face ventral do hemíptero. Os vermes adultos eram pigmentados (marrom-esverdeado, mimetizando a cor do exoesqueleto de seus hospedeiros. A nova espécie é semelhante à Temnocephala decarloi Moretto, 1978, descrita da Argentina, única espécie conhecida do gênero já encontrada sobre hemípteros belostomatídeos, por ter um cirro extremamente longo e curvo, mas difere desta por ter a porção distal do 'introvert' sem a forma típica de um cachimbo ('full-bent' como ilustrada pelo autor na descri

    Full Text Available RESUMOObjetivou-se com este trabalho comparar o padrão de crescimento, mediante ajustes das respectivas curvas de crescimento por modelos não lineares, bem como estudar o desenvolvimento de cortes de carcaça em relação ao peso da carcaça em diferentes genótipos de frangos tipo caipira. Foram utilizados 840 pintos de um dia, machos, distribuídos em delineamento inteiramente ao acaso, dos seguintes genótipos da linhagem Redbro: Caboclo, Carijó, Colorpak, Gigante Negro, Pesadão Vermelho, Pescoço Pelado e Tricolor. As aves foram alojadas em 28 boxes, sendo 30 aves/boxe, em galpão de alvenaria com acesso a um piquete de 45m², com quatro repetições. O peso corporal individual dos frangos foi medido ao nascer, aos 14, 28, 42, 56, 70 e 84 dias de idade. Para a determinação das curvas de crescimento do peso corporal das aves, os dados coletados foram avaliados por meio dos modelos não lineares: Brody, Gompertz, Logístico, Richards e von Bertalanffy. Foi empregado o PROC NLIN do SAS, utilizando-se o método interativo de Gauss-Newton. Os critérios usados para escolha do modelo de melhor ajuste da curva de crescimento foram o coeficiente de determinação, o desvio padrão assintótico, o desvio médio absoluto dos resíduos e o índice assintótico. As análises para obtenção dos coeficientes alométricos foram realizadas por meio do PROC GLM do SAS para os genótipos Carijó, Colorpak, Pesadão Vermelho, Pescoço Pelado e Tricolor. Foram avaliados os pesos da carcaça, do peito, das coxas, das sobrecoxas, das pernas e das asas das aves abatidas aos 85 dias de idade. Apenas as equações propostas por Gompertz, von Bertalanffy e Logístico atingiram a convergência, e o modelo proposto por von Bertalanffy foi o mais adequado para descrever o crescimento dos genótipos de frangos caipiras. Todos os cortes avaliados apresentaram crescimento tardio em relação ao peso da carcaça em genótipos de frangos tipo caipira.

    Full Text Available Casos de tenossinovite numa empresa metalúrgica foram analisados através da Análise Coletiva do Trabalho, da qual participaram treze trabalhadores e o Sindicato da categoria. A partir da descrição de sua atividade de trabalho, feita em duas reuniões coletivas, ficou claro que a tenossinovite era um termo geral utilizado para várias queixas (dores, formigamento, perda de força dos membros superiores e inferiores que acometiam os trabalhadores. O problema atingia trabalhadores de vários setores da empresa, cujas tarefas exigiam movimentos estereotipados, localizados e repetidos dos braços ou pernas e um ritmo de trabalho elevado. Os casos aumentaram quando houve uma reorganização da produção da empresa, com a introdução de células de produção, Kanban e polivalência dos operários, reorganização que foi apresentada aos trabalhadores sob o nome de "Escravos de Jó". O artigo termina com comentários sobre a intensificação do trabalho, no Brasil e no mundo, provocada pelas novas formas de organização da produção e a necessidade de levá-la em consideração nos estudos técnicos sobre a gênese das L.E.R.Tenosynovitis cases in a metal plant were studied using the Collective Work Analysis, involving 13 workers and their union. From the description of their work activities, during two group meetings, it became clear that tenosynovitis was a generic term used to describe several complaints (pains, loss of strenght of the the superior and inferior limbs, suffered by the workers. The problem afflicted workers of several sectors of the company, whose tasks required stereotyped, repetitive and localized movements of the arms or legs and a high work rate. The number of cases rised when the company reorganized its production, introducing productions cells, Kanban and multivalence of workers, reorganization presented to the workers under the name of "escravos de Jó".

Foram utilizadas 540 aves, machos, da marca comercial Cobb, distribuídas em delineamento inteiramente casualizado, em esquema fatorial 3x2, ou seja, 3 níveis de aminoácidos (metionina, metionina+cistina, lisina e treonina - 100%, 125% e 150% NRC,1994 e 2 níveis de cálcio (75% e 100% NRC,1994, com 3 repetições de 30 aves cada. Os aminoácidos estudados foram metionina, metionina+cistina, lisina e treonina. O desempenho das aves foi avaliado pelo peso vivo, ganho de peso, consumo de ração e conversão alimentar. O rendimento de carcaça e a percentagem de cada parte foram avaliados de 2 aves de cada repetição, escolhidas ao acaso, perfazendo um total de 6 animais por tratamento. O rendimento de carcaça foi realizado após o abate levando-se em consideração a percentagem de peito, pernas (coxa+sobrecoxa, asas, dorso, cabeça+pescoço e pés em relação à carcaça eviscerada. Além disso, analisou-se o cálcio excretado pelas aves. Para tanto, utilizou-se 72 aves, alojadas em gaiolas, seguindo o mesmo delineamento descrito anteriormente. Não houve interação entre os fatores estudados para as características avaliadas. As que consumiram dietas com 125% e 150% de aminoácidos apresentaram melhor conversão alimentar. O rendimento de peito foi afetado pelos níveis de cálcio.

    This review focuses on traditional and contemporary anti-inflammatory uses of mollusc-derived products summarising all the in vitro, in vivo and human clinical trials that have tested the anti-inflammatory activity of molluscan natural products. Inflammatory conditions, burns and wounds have been an ongoing concern for human health since the early era of civilisation. Many texts from ancient medicine have recorded the symptoms, signs and treatments for these conditions. Natural treatments are well-documented in traditional European medicine, Traditional Chinese Medicine (TCM), Siddha and ancient Mediterranean and African traditional medicine and include a surprisingly large number of molluscan species. An extensive review of the Materia Medica and scientific literature was undertaken using key word searches for "mollusc" and "anti-inflammatory" or "immunomodulatory" or "wound healing". Molluscs have been used in ethnomedicine by many traditional cultures to treat different aspects of inflammatory conditions. We found 104 different anti-inflammatory preparations from a variety of molluscan species, of which 70 were from the well-documented Traditional Chinese Medicine (TCM). This traditional use of molluscs has driven the testing for inflammatory activity in extracts from some species in the phylum Mollusca, with 20 in vitro studies, 40 in vivo animal studies and 14 human clinical trials performed to substantiate the anti-inflammatory and wound healing activity of molluscs. Some of these studies have led to the approval of mollusc-derived products to be used as over-the-counter (OTC) nutraceuticals, like Lyprinol® and Biolane™ from the New Zealand green lipped mussel Perna canaliculus. Natural products provide important leads for the development of pharmaceuticals, including anti-inflammatory agents. Only a small proportion of the molluscan traditional medicines have been tested to confirm their anti-inflammatory activity and most screening studies have tested

    Full Text Available O objetivo do estudo foi descrever o perfil epidemiológico dos casos e óbitos de beribéri notificados de 2006-2008 no Estado do Maranhão, Brasil. Informações foram obtidas de fichas de notificação da Secretaria de Estado da Saúde do Maranhão e utilizou-se o Índice Global de Moran para avaliar autocorrelação espacial. Foram notificados 1.207 casos e 40 óbitos. Regiões oeste e central mostraram forte presença de autocorrelação espacial da incidência. Ocorrência de casos e óbitos concentrou-se de maio a agosto, em homens jovens (20-40 anos. Hábito de consumir álcool e fumar esteve presente entre os óbitos; baixa renda e ocupação com atividade pesada, entre os casos. Os sintomas mais comuns foram diminuição da força, dormência e edema das pernas, dificuldade para caminhar e dor na panturrilha. O perfil dos acometidos e os sintomas, exceto edema de membros inferiores, são característicos de beribéri seco. É pertinente que estudos sobre seu ressurgimento no país sejam aprofundados.This study aimed to describe the epidemiological profile of beriberi cases and related deaths reported from 2006 to 2008 in Maranhão State, Brazil. Data were obtained from beriberi notification forms at the State Health Department. The global Moran index was used to evaluate spatial auto-correlation. 1207 cases and 40 deaths were reported. The western and central regions of the State showed strong spatial auto-correlation of incidence rates. Cases and deaths were concentrated from May to August, in young men (20-40 years. Regular alcohol consumption and smoking were recorded among fatal cases. Low income and heavy labor were widespread among cases. Common symptoms were asthenia, numbness, and swollen legs, difficulty walking, and calf pain. The profile of cases and their symptoms (except swollen legs are characteristic of dry beriberi. We recommend further studies on the resurgence of beriberi in Brazil.

    Full Text Available O nervo isquiático é considerado o maior nervo do corpo, pertence tanto ao plexo sacral quanto ao lombossacral em carnívoros, continuando até a extremidade distal do membro pélvico, recebe fiibras dos ramos ventrais do sexto e sétimo nervos lombares e do primeiro nervo sacral. O objetivo do presente estudo é descrever a distribuição do nervo isquiático em mão-pelada (Procyon cancrivorus e comparar com dados literários de animais domésticos e silvestres. Os animais são procedentes de coleta em rodovias, entre as cidades de Goiânia e Jataí, principalmente na BR 364 ou BR 060. (mortos por acidente e fiixados em solução aquosa, a 10% de formaldeído. Doados ao Museu de Anatomia Humana e Comparada da UFG (Universidade Federal de Goiás, Campus de Jataí, Proc.CAJ-287/2008. As dissecações e documentação fotográfiica permitiram observar a distribuição do nervo isquiático. O nervo isquiático de mão-pelada inerva o membro pélvico passando entre os músculos glúteo médio e profundo, emitindo ramos para a musculatura da região glútea e da coxa, respectivamente, para os músculos glúteo médio, glúteo bíceps, semimembranáceo, semitendíneo, bíceps femoral, gêmeos, quadrado femoral e adutor magno, emitindo nervo cutâneo lateral e caudal da sura para suprir a pele na superfiície lateral e caudal da perna, respectivamente. Próximo ao meio da coxa bifurca-se em nervo tibial e nervo fiibular comum. O conhecimento anatômico da origem e distribuição do nervo is quiático em mão pelada quando comparado com animais domésticos, silvestres e de fazenda, mostram um padrão de inervação semelhante entre os espécimes.

    The Gulf of Paria is bordered by both Trinidad and Venezuela, from which various metallic pollutants and other contaminants can originate. The Gulf is still a significant source of fish, crabs and shellfish for human consumption to both countries, where concerns over the quality of this marine environment have been long expressed but never properly addressed. In addition, the circulatory current patterns in the Gulf ensure that contaminants originating from either country are likely to affect both countries eventually. Heavy metals were determined in oysters (Crassostrea rhizophorae and C. virginica), green mussels (Perna viridis) and sediments from the Gulf of Paria. Samples were obtained at four sites in Trinidad and three sites in Venezuela in the Gulf of Paria, in addition to comparative samples collected from three sites on the north coast of Venezuela. Edible tissues of twelve shellfish from each location were blended and aliquots digested with concentrated nitric acid, for extraction of cadmium, chromium, copper, lead, nickel and zinc. The solutions were analysed by flame atomic absorption spectroscopy. Mercury was extracted with a mixture of nitric, hydrochloric and sulphuric acids and determined by cold vapour atomic absorption. Sediments were oven-dried at 60 0 C, before being similarly extracted. Results showed that mercury in sediments at all sites in Trinidad and Venezuela exceeded NOAA and Canadian sediment quality guidelines, while cadmium, copper, nickel, lead and zinc also exceeded these guidelines at several sites. Heavy metal levels in oysters and green mussels varied widely with location. However, oysters from the Gulf of Paria contained significantly higher mean levels of cadmium, copper, nickel and zinc than those from the north coast of Venezuela, but this difference was not apparent in mussels. Cadmium, mercury and zinc in sediments were significantly correlated with those of mussels, but not of oysters, in which copper and zinc at several

    Full Text Available Introdução: Colchicina é a viga-mestra para o tratamento de FFM, que é uma doença autoinflamatória com polisserosite recidivante como principal manifestação. Apesar de doses diárias de 2 mg ou mais/dia, aproximadamente 5%-10% dos pacientes continuam a sofrer de seus ataques. Neste estudo, objetivamos investigar os aspectos da depressão e dos ataques em pacientes com FFM apresentando resistência à colchicina (RC. Pacientes e Métodos: Em pacientes com FFM, RC foi definida como dois ou mais ataques nos últimos seis meses, quando em medicação com colchicina 2 mg/dia. Dezoito pacientes (nove mulheres e nove homens foram recrutados no grupo RC e 41 pacientes no grupo de controle (29 mulheres/12 homens. Foram avaliados os achados demográficos, clínicos e laboratoriais, a fidelidade ao tratamento e os escores do Beck Depression Inventory (BDI. Resultados: A idade de surgimento da FFM foi significativamente menor no grupo RC (12,3 anos vs. 16,9 anos, P = 0,03. A duração da doença foi maior no grupo RC (p = 0,01. Dores abdominais e nas pernas em decorrência do exercício foram significativamente mais frequentes no grupo RC versus controles (83% vs. 51%; p = 0,02 e 88% vs. 60%; p = 0,04, respectivamente. Pacientes com escores BDI > 17 pontos foram mais frequentes no grupo RC versus controles (50% vs. 34,1%; p < 0,001. Discussão: Verificamos que: (1 a idade do surgimento da doença foi mais baixa e (2 a duração da doença foi maior no grupo RC. Ataques pleuríticos, hematúria e proteinúria foram mais frequentes em pacientes com RC. Propomos que a depressão é fator importante a ser levado em consideração na sensibilidade à RC.
