| ABSTRACT The aim of this study was to evaluate the possible protective of C. guianensis oil against MMC and CP, which are direct- and indirect-acting chemical mutagens, using the micronucleus test. Three experiments were performed. First the C. guianensis oil was co-administered to mice at doses of 250, 500 and 1000 mg/kg bw with 4 mg/kg bw MMC or 50 mg/kg bw CP. Second, the mutagenic drug (CP) was administered ip 50 mg/kg bw and after 6 and 12 hours 250 and 500 mg/kg bw of C. guianensis oil were administered. In the last, C. guianensis oil was administrated (250 and 500 mg/kg bw) during five days and after it was administered ip 50 mg/kg bw CP. The results obtained showed that the C. guianensis oil is not cytotoxic neither genotoxic to mouse bone marrow.... |

| When oil spills occur, behavior is the first line of defense for a fish to avoid being contaminated. Here, we determined the avoidance threshold of the European seabass (Dicentrarchus labrax) to the water-soluble fraction (WSF) of oil using a dual flow choice box. Our experiment revealed that a plume of 20%-diluted WSF (total PAH concentration: 8.54 μg L-1) triggered a significant avoidance response that was detected within 7.5 minutes of introducing WSF-contaminated water in the experimental set-up. However, the ecological relevance of seabass capacity to detect and avoid WSF remains to be established. In the short term, such response is indeed liable to reduce sea bass contact time with oil-contaminated water and thus preserve their functional integrity.... |

| El ambiente marino posee una pobre capacidad de respuesta al impacto de los hidrocarburos petrolí-feros, tanto por la baja concentración de nutrientes disponibles (nitrógeno y fósforo), como por la baja frecuencia de aparición de bacterias hidrocarbonoclastas. Teniendo en cuenta la posibilidad que ofrecen las células inmovilizadas de transformar los hidrocarburos del petróleo sin que ocurra dupli-cación celular, en este trabajo se realizó un estudio de la necesidad o no de añadir nutrientes al BIO-IL (producto hidrocarbonoclasta a partir de células inmovilizadas). Se demostró por Cromatografía Gaseosa de Alta Resolución, que no es necesario añadir nutrientes al agua de mar para que ocurra una degradación eficiente de los hidrocarburos del petróleo por... |

| Apparent digestibility coefficients and serum parameters were measured to evaluate the effect of supplementing feed concentrates with rice bran oil in horses. Twelve horses (6 males and 6 females) with a mean age of 18 ± 4 months old and mean live weight of 306 ± 22.6 kg were used. Treatments consisted of increasing rice bran oil concentrate levels of 0, 3.5, 7.0, 10.5, 14.0 and 17.5%, considering a daily intake of 2.25% live weight on a dry matter basis. A dietary effect of supplementation on the apparent digestibility of gross energy (y = 64.55 - 0.58x) was observed (P<0.05). No effect on the other nutrients was observed (P>0.05). Supplementation did not affect serum glucose levels (P>0.05), but cholesterol was affected (P<0.01) based... |

| Background: Different parts of the tree Calophyllum inophyllum L. (nuts, leaves, roots, bark, fruits, nut oil and resin) are used as traditional medicines and cosmetics in most of the Pacific Islands. The oil efficiency as a natural cure and in traditional cosmetics has been largely described throughout the South Pacific, which led us to investigate C. inophyllum's chemical and genetic diversity. A correlative study of the nut resin and leaf DNA from three distinct archipelagos in the South Pacific was carried out in order to identify diversity patterns in C. inophyllum across the South Pacific. Methods: Calophyllum inophyllum plants were sampled from French Polynesia, New Caledonia and Fiji. We extracted tamanu oil (nut oil) resin for chemo-diversity... |

| Germplasm collections are the main raw material for breeding programs. Peanut is an important oilseed that serves to oil and food markets. The identification of early-mature genotypes and earliness adds benefits to crop production as it minimizes the costs of management and the losses of pod production due to occurrence of dry periods. In this paper, we estimate the genetic divergence in 77 peanut accessions (subsp. fastigiata), using three clustering methods, in order to identify early-mature genotypes and earliness for food market. The accessions were grown in field and phenotyped for 19 qualitative and quantitative traits. The Tocher methodology was employed for discriminating Valencia accessions. Both UPGMA and Principal Components Analysis (PCA) were... |

| Abstract The vast Amazon region has considerable territorial peculiarities and plant species diversity, sometimes from the same botanical family, which can exhibit significant differences in physicochemical properties. From this diversity, two species stand out – Amazonas tucumã (Astrocaryum aculeatum Meyer) and Pará tucumã (Astrocaryum vulgare Mart.). The research focus is to analyze, comparatively, these oleaginous fruits, their similarities, particularities and potentials regarding the oil quality extracted from two tucumã varieties from the states of Amazonas and Pará, obtained using supercritical carbon dioxide, under different extraction parameters. The results demonstrate the biometric particularities of each species, highlighting the Amazon fruit,... |

| O girassol e uma planta originaria das Americas, que foi utilizada como alimento, pelos indios americanos em mistura com outro vegetais. No seculo XVI, o girassol foi levado para a Europa e Asia, onde era utilizada como uma planta ornamental e como hortalica. Foram na Uniao Sovietica os primeiros trabalhos de melhoramento genetico visando a producao de genotipos com altos teores de oleo comestivel. Atualmente, o girassol ocupa o quarto lugar como fonte de oleo, em relacao a soja, palma e canola. Como fonte proteica, o girassol tambem e classificado como a quarta opcao, para racao animal e uso humano. Os derivados proteicosde girassol, que podem ser utilizados como ingrediente alimentar, incluem a farinha, o concentrado e o isolado proteico. O conteudo de... |

| Olive is one of the strategic products in Iran, and due to the significant cultivation area of this product, oil companies should be equipped with suitable processing equipment. Unfortunately, despite the high capacity of olive in Iran, oil companies are equipped with imported machines. In this study, the construction and evaluation of the Three-counter device of Iran has been developed. The machine has three oil, water and olive pulp outputs. In order to evaluate the machine, the amount of moisture content and fat extracted from the machine was checked at 2500 and 3500 rpm and 30 and 45% water content. Also, four different samples Manzallina, Fishemi, Kalamata and Oily were used in this experiment. The main components of the machine include an electric... |
