| A gueroba, guariroba ou gariroba e uma palmeira importante para a populacao do Cerrado, sendo extraido dela um palmito de sabor amargo muito apreciado na culinaria regional. Esse produto e comercializado, geralmente, in natura e sua industrializacao ainda e artesanal. Seu principal mercado localiza-se nos Estados de Goias, Tocantins, Mato Grosso, Mato Grosso do Sul, algumas regoes da Bahia e de Minas Gerais e no Distrito Federal. Com a exploracao predatoria e a acelerada destruicao da vegetacao nativa por meio da expansao da fronteira agricola, a oferta do produto, oriunda do extrativismo, vem sendo reduzida substancialmente. No entanto, tem-se observado o cultivo dessa palmeira em alguns Estados, principalmente em Goias que, em 1999, cultivava 4.499... |

| Academia and management agencies show a growing interest for ecosystem-based fishery management (EBFM). However, the way to operationalize this approach remains challenging. The present paper illustrates how the concepts of stochastic co-viability, which accounts for dynamic complexities, uncertainties, risk and sustainability constraints, can be useful for the implementation of EBFM. In the present case, this concept is used to identify fishing strategies that satisfy both ecological conservation and economic sustainability in a multi-species, multi-fleet context. Economic Viability Analysis (EVA) and the broader Co-Viability Analysis (CVA), are proposed to expand the usual Population Viability Analysis (PVA) and precautionary approach. An illustration is... |

| Epilachna paenulata (Germar, 1824) was reared feeding on pumpkin leaves (Cucurbita pepo Lourt.) in laboratory conditions at temperatures of 20±0,5ºC, relative humidity of 65±0,5% and 12 hour photoperiod. Groups of fecunded and non-fecunded females were studied. The ovarioles showed four developing stages during egg production, morphologically alike for fecunded and non-fecunded females, but differing in the duration time of the stages. Each ovarium has 24 ovarioles on average, less than any other species known into the genus, and all ovarioles are physiologically active at each oviposition. The mean number of ovarioles is lower when compared with the other species of Epilachninae known. Fecunded and non-fecunded females showed a similar preoviposition... |

| ALT-C, an ECD motif (glutamic acid, cysteine, aspartic acid) disintegrin from Bothrops alternatus snake venom, induces α2β1 integrin-mediated signaling and neutrophil chemotaxis. In vitro, in human umbilical vein endothelial cells (HUVEC), ALT-C induces cell proliferation, thus showing an interesting potential for tissue regeneration studies. This work aimed to evaluate the influence of ALT-C in myoblast viability and differentiation. Myoblasts were obtained from hind limb muscles of 3 to 4-day old Wistar rats. The cells were incubated with ALT-C at different concentrations and incubation periods were followed by total RNA isolation. cDNA synthesis and real time polymerase chain reaction (PCR) were performed with primers of myoD as well as of both (slow... |

| This study aimed at the technical-economical evaluation of implanting some vegetal-oil extraction units in order to insert the family agriculture into bio-diesel production chain. Three project models (arrangements) for vegetal-oil extraction units at different sizes were proposed, using extraction by pressing and mixed extraction (extracting by either pressing or solvent) and different raw materials (castor-oil and soybean). For the size analysis, the oil production scales between 50/60 tons/day were used with real market data concerning investments, inputs prices of the process, raw materials and vegetal oil. For the economic analyses, the software BioSoft was used. The BioSoft is a program for supporting the decision-making process, which was developed... |

| During the austral summer, we examined the bacterial population along the cruise track extending from 70degrees S and 18degrees E to 30degrees S and 35degrees E. During the cruise, three distinct fractions of the bacterioplankton viz. total count, total direct viable and retrievable counts were simultaneously enumerated in these waters. In the stations south of the convergent region designated as section I the population ranged within 10(8-9) L-1 whereas in the north of the region designated as section 11 they were one order higher and ranged from 10(9-10) L-1. The percentage of viability in the region was high corresponding to the generally high chlorophyll and primary productivity encountered in the eastern Aghulas bank. The study substantiates the... |

| Fertilization of the oocyte is a critical process of sexual reproduction depending among other factors on spermatozoa functionality. Mitochondria participate in many crucial processes for spermatozoa motility and fertilizing ability. The Pacific oyster, Crassostrea gigas, is characterized by a high inter-individual variability of its reproductive success which has been shown to be partially due to the variability of gamete quality. The present study explored spermatozoa characteristics such as: i) relationships among mitochondrial functionality (ATP content, mitochondrial membrane potential (MMP), reactive oxygen species production); sperm viability (percentages of live, dying, and dead); and motility; and ii) their involvement in inter-oyster variability... |

| The aim of this study was to evaluate the sensitivity of Campomanesia adamantium seeds to desiccation by drying in activated silica gel (fast) and under laboratory conditions (slow). To assess the sensitivity of the seeds to desiccation, we used drying with silica gel and drying under laboratory conditions (25 °C), in order to obtain seeds with moisture content of 45, 35, 30, 25, 20, 15, 10 and 5%. The physiological potential of the seeds after desiccation was evaluated by measuring primary root protrusion, percentage of normal seedlings, germination seed index, seedling length, total seedling dry mass, electrical conductivity and DNA and RNA integrities. The C. adamantium seeds were sensitive to desiccation and to a reduction in moisture content to 21.1%... |

| Parasitic worms (helminths) within the Phyla Nematoda and Platyhelminthes are responsible for some of the most debilitating and chronic infectious diseases of human and animal populations across the globe. As no subunit vaccine for any parasitic helminth is close to being developed, the frontline strategy for intervention is administration of therapeutic, anthelmintic drugs. Worryingly, and unsurprising due to co-evolutionary mechanisms, many of these worms are developing resistance to the limited compound classes currently being used. This unfortunate reality has led to a renaissance in next generation anthelmintic discovery within both academic and industrial sectors. However, a major bottleneck in this process is the lack of quantitative methods for... |

| ABSTRACT A cytotoxicity study is performed on a poly(methyl methacrylate) polymer (PMMA) to be used for the fabrication of bone tissue by Rapid Prototyping (RP). The solution polymerization is conducted in a pilot plant reactor using more appropriated reagents in consideration of the medical application. Moreover, the polymer is efficiently handled to avoid the side effect of the monomer, reducing the concentration of this specie to 287,731 µg MMA/kg PMMA. The cytotoxicity of the polymer is determined through growth monitoring, adherence and morphology of L-929 cells. Additionally, MTT and LIVE/DEAD tests are performed. The results showed continuous and progressive growth of the cells on the surface of the specimens. Moreover, the material did not... |

| La producción de “setas” (Pleurotus ostreatus), es una alternativa para producir y diversificar los alimentos que requiere la población en México. En el país es escasa la información acerca de la rentabilidad de éste cultivo. Por ello, el objetivo de este trabajo fue estimar una función de producción que muestre matemáticamente la relación funcional entre los insumos productivos utilizados y la producción “setas”. La variable dependiente la constituyó la producción de “setas” producidas y la variable independiente fueron las bolsas en producción. Los resultados económicos mostraron que la etapa de producción II, la que es económicamente relevante, se inicia en el punto donde se encuentran en el área de producción 2449 bolsas y termina donde el producto... |

| ABSTRACT Dairy products are the primary delivery for probiotics, with great popularity among the public looking for functional foods. The addition of probiotics to new food matrices requires studies about the stability and viability of these microorganisms in the final product. This study aimed to develop a probiotic smoothie beverage and to evaluate the microbiological quality, pH, acidity, syneresis, probiotics viability, sensory acceptance, and consumers’ preference. For that, thirty-six beverage formulations were prepared using yogurt and different fruit pulps. Six formulations were selected for the study, as follows: probiotic yogurt with the addition of mango pulp, grape, red fruits (containing 8 and 10% sucrose), mango/passion fruit, and red... |

| Terrestrial and marine biodiversity provides the basis for both ecosystems functioning and numerous commodities or services that underpin human well-being. From several decades, alarming trends have been reported worldwide for both biodiversity and ecosystem services. Therefore the sustainable management of biodiversity requires a double viewpoint balancing ecological conservation with the welfare of human societies. Understanding the underlying trade-offs, synergies and interactions imposes the development of interdisciplinary researches and methods. In that respect, bio-economic or ecological economic modeling is likely to play a major role. The present paper intends to elicit the key features, strengths and challenges of bio-economic approaches... |

| Reconciling food security, economic development and biodiversity conservation is a key challenge, especially in the face of the demographic transition characterizing many countries in the world. Fisheries and marine ecosystems constitute a difficult application of this bio-economic challenge. Many experts and scientists advocate an ecosystem approach to manage marine socio-ecosystems for their sustainability and resilience. However, the ways by which to operationalize ecosystem-based fisheries management (EBFM) remain poorly specified. We propose a specific methodological framework-viability modelling-to do so. We show how viability modelling can be applied using four contrasted case-studies: two small-scale fisheries in South America and Pacific and two... |

| This paper applies a stochastic viability approach to a tropical small-scale fishery, offering a theoretical and empirical example of ecosystem-based fishery management approach that accounts for food security. The model integrates multi-species, multi-fleet and uncertainty as well as profitability, food production, and demographic growth. It is calibrated over the period 2006–2010 using monthly catch and effort data from the French Guiana's coastal fishery, involving thirteen species and four fleets. Using projections at the horizon 2040, different management strategies and scenarios are compared from a viability viewpoint, thus accounting for biodiversity preservation, fleet profitability and food security. The analysis shows that under certain... |
