| Wild mushrooms have been described as sources of natural antioxidants, particularly phenolic compounds. However, many other compounds present in wild mushrooms can also act as antioxidants (reducers), so whole extracts from a wide range of species need to be examined. To gain further knowledge in this area, the relationship between the antioxidant potential (scavenging effect and reducing power) and chemical composition of twenty three samples from seventeen Portuguese wild mushroom species was investigated. A wide range of analytical parameters reported by our research group (including ash, carbohydrates, proteins, fat, monounsaturated fatty acids, polyunsaturated fatty acids, saturated fatty acids, phenolics, flavonoids, ascorbic acid and -carotene)... |

| The objective of this study was to evaluate the acaricidal activity of the volatile oils of three species of Croton, Euphorbiaceae, against the cattle tick Rhipicephalus microplus. The volatile oils were obtained by hydrodistillation, analyzed by GC?MS and GC-FID and their acaricidal activity was evaluated by the larval packettest and adultimmersion test. The volatile oils from Croton conduplicatus Kunth, Croton pulegiodorus Baill., and two different collections of Croton grewioides Baill. (CG1 and CG2) showed eucalyptol (24.09%), p-cymene (23.13%) and methyl chavicol (83.59% and 95.38%) as the major compounds, respectively. All the volatile oils tested in this study showed efficacy against larvae and engorged females of Rhipicephalus microplus. Therefore,... |

| Visando avaliar os efeitos de fertilizantes sobre os rendimentos de matéria seca (MS) e composição química do Sty/osanthes guíanensís, cv. Cook e Pueraría pbeseoioides, com e sem calcário, foi realizado um ensaio, num Latossolo Amarelo, com tratamentos em parcelas subdivididas (7x2), sendo constituídos por 7 tipos de adubação: 1 - Sem adubação, 2 - Fósforo (P), 3 - P + Potássio (K), 4 - K , 5 - Nitrogênio (N), 6 - NPK e 7 - NPK+micronutrientes (NPKM); e 2 quantidades: O e 2 tlha. A calagem não influenciou a produção de matéria seca (MS), porém elevou os teores de Ca de ambas leguminosas Os teores de proteína bruta e fósforo foram aumentados com a fertilização. As produções de MS das leguminosas foram consideravelmente aumentadas com adição de... |

| This study aimed to evaluate the agronomic characteristics and nutritional value of two clones of elephant grass (CNPGL 00-1-3 and BRS Kurumi) operating under rotational stocking in the dry season. A completely randomized design with repeated measures (grazing cycles) and three replicates (paddocks) was used. Clones were managed under rotational stocking with a defoliation interval of 24 days and four days of occupation of paddocks, using Holstein x Gyr heifers with mean body weight of 150 kg. The evaluations were conducted in April/May, May/June, June/July and July/August 2010. Green forage mass was influenced by clone and grazing cycle, with higher mean value observed for CNPGL 03-01-00, which was 17% higher than the value observed for BRS Kurumi, and... |

| Water-soluble sulfated polysaccharides isolated from two red algae Sphaerococcus coronopifolius (Gigartinales, Sphaerococcaceae) and Boergeseniella thuyoides (Ceramiales, Rhodomelaceae) collected on the coast of Morocco inhibited in vitro replication of the Human Immunodeficiency Virus (HIV) at 12.5 mu g/mL. In addition, polysaccharides were capable of inhibiting the in vitro replication of Herpes simplex virus type 1 (HSV-1) on Vero cells values of EC(50) of 4.1 and 17.2 mu g/mL, respectively. The adsorption step of HSV-1 to the host cell seems to be the specific target for polysaccharide action. While for HIV-1, these results suggest a direct inhibitory effect on HIV-1 replication by controlling the appearance of the new generations of virus and... |

| Chemical aspects of the San Jorge Gulf benthic system, Argentina (2005-2010). A new contribution on the chemical aspects of the San Jorge Gulf benthic system in the distribution area of shrimp Pleoticus muelleri (Spence Bate, 1888) during 2005-2010 is presented. Concentration of dissolved oxygen in bottom water and mix layer and of total organic matter (TOM), total organic carbon (TOC), total nitrogen (TN), chlorophyll a (Chl a) and phaeopigments (Phaeo) in surficial sediments were analyzed. The origin and nutritional value of TOM deposited were also assessed through the C:N ratio. Water samples were collected during the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) seasonal research cruises in the period 2005-2010. Sediment samples... |

| Pairs of soybean seeds and their correspondent expeller samples were collected from ten extrusion-expelling processing plants in Argentina. Seeds were analyzed for proximal composition, bulk moisture content (MC) and individual seed MC. Expeller were analyzed for proximal composition, bulk MC, protein solubility in KOH, expeller urease activity and free fatty acid content. Results indicated that average soybean composition was 136 g/kg MC, 207 g/kg oil and 391g/kg crude protein (CP), while the oil extraction efficiency (OEE) of the process was of 60.7%. The expeller composition was 922 g/kg dry matter (DM), 81g/kg oil and 442 g/kg CP. In soybean seeds, coefficient of variation (CV) of MC was 17.2%, 3.0% for CP and 5.1% for oil, while in SBE CV for DM was... |

| Resumo: Objetivou-se avaliar a composição química do capim-elefante adubado com crescentes doses de composto orgânico produzido a partir de resíduos da produção e abate de pequenos ruminantes. O delineamento foi em blocos casualizados com 6 tratamentos e 4 blocos, totalizando 24 parcelas, sendo aplicadas as seguintes doses (t ha-1): zero; 13,3; 26,6; 39,9; 53,2 e 79,8. Para a diagnose do estado nutricional do capim-elefante, coletou-se 7 amostras simples por parcela, em zigue-zague, de maneira aleatória. A região avaliada foi a primeira folha recém-expandida, sendo as amostras simples as plantas de uma mesma touceira, ao sexagésimo dia após o corte de uniformização. Avaliou-se a análise de macro e micronutrientes do capim-elefante. Houve efeito... |
