| 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)... |

| 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... |

| O presente trabalho teve como objetivo avaliar os teores de trigonelina, ácidos clorogênicos (5-ACQ) e cafeína em grãos de diferentes cultivares de cafeeiro (Coffea arabica L.). As cultivares avaliadas foram coletadas na Fazenda Experimental da Epamig em Lavras, Estado de Minas Gerais, no ano agrícola de 2005/2006. O delineamento experimental utilizado foi um inteiramente casualizado constando de oito cultivares de café com três repetições. Foram avaliadas as cultivares: Oeiras MG 6851, Acaiá Cerrado MG 1474, Catuaí Vermelho IAC 99, Rubi MG 1192, Topázio MG 1190, Mundo Novo IAC 379/19, Catucaí Amarelo 2 SL e Catuaí Amarelo IAC 62. Após a colheita dos cafés por derriça manual no pano, estes foram lavados e submetidos ao processo de descascamento e... |

| During april 1995 hydrochemical research in a vertical column on the east side of the Galápagos Islands (Cruise T95/04/01) onboard of the INP R/V Tohallí indicated that concentrations of ammonium, nitrate, phosphate and chlorophyll-a were found stratified from the surface to deeper layers, on the other hand the maximum levels of nitrite and silicate were detected 70 m below the thermocline. The apparent oxygen use (AOU) varied from 1 to over 3 below the thermocline, this would indicate an oxidating environment due to the high levels of nitrate, phosphate, silicate and low concentrations of dissolved Oxygen (ca. 90-134[µM]) and ammonium (<0,1[µM]). According to the high salinity average (35,0 ups), nutritive elements (nitrate 15,6 [µM], silicate 13,1... |

| La concentración de nutrientes en las aguas del Pacífico ecuatoriano durante el período pre-invernal de septiembre y diciembre de 1990 estuvo influenciada, principalmente, por el transporte estacional de aguas oceánicas de diferentes orígenes. La migración de los organismos acuáticos, los procesos biológicos de utilización y mineralización, la sedimentación de las partículas orgánicas a través de la columna de agua, y el drenaje continental, podrían haber influenciado, en menor proporción, las propiedades químicas del área. Durante el crucero llevado a cabo en los meses de septiembre y octubre de 1990, las aguas peruanas de mayor densidad y ricas en nutrientes fueron fácilmente observables a lo ancho del transecto del meridiano 82ºW. Por otro lado las... |

| RESUMO: O experimento foi instalado num Latossolo Vermelho com a cultivar Mundo Novo MN 379-19 na Embrapa Cerrados em Planaltina - Distrito Federal. Os tratamentos tiveram início no ano agrícola de 1997/1998 e apresentaram as seguintes doses: 0, 100, 200, e 300 kg/ha/ano na forma de uréia, aplicados, a lanço, embaixo da saia do cafeeiro, 100/kg/ha/ano na forma de uréia, aplicados no sulco, paralelo à projeção da copa e 100 kg/ha/ano na forma de nitrato de amônio, aplicados a lanço, embaixo da saia. As doses começaram a ser ministradas no início da época chuvosa (outubro de 2001) em quatro parcelamentos. As amostras de solo foram retiradas de entre as linha, na projeção da copa e sob a saia do café, nas profundidades de 0 a 5, 0 a 10, 0 a 20, 20 a 40 e 40 a... |

| Four Venda indigenous scavenging (VIS) chickens (one young male and one young female of 10-16 weeks of age, a mature cockerel and a mature hen) were randomly purchased from each of six adjacent rural villages during three different seasons (autumn, winter and spring) to determine the meat yield and carcass chemical composition. A total of 72 chickens were slaughtered and feathers, head, neck, viscera, feet and lungs were removed. The live body weight, dressed carcass weight and also the mass of the breast without wings, thighs and drumsticks were recorded with bones and skin. The muscle tissues of the breast and both legs without tendons and fat were sampled for chemical analysis and were analysed for dry matter, ether extract, crude protein and ash. The... |
