Microsatellite Markers Reveal Strong Genetic Structure in the Endemic Chilean Dolphin

Creator:: José Pérez-Alvarez, María, Olavarría, Carlos, Moraga, Rodrigo, Baker, C. Scott, Hamner, Rebecca M., and Poulin, Elie
Abstract:: Understanding genetic differentiation and speciation processes in marine species with high dispersal capabilities is challenging. The Chilean dolphin, Cephalorhynchus eutropia, is the only endemic cetacean of Chile and is found in two different coastal habitats: a northern habitat with exposed coastlines, bays and estuaries from Valparaíso (33°02' S) to Chiloé...

Antioxidant activity of fractions from Quercus sideroxyla bark and identifi cation of proanthocyanidins by HPLC-DAD and HPLC-MS

Creator:: Rosales-Castro, Martha, Gonzalez-Laredo, Ruben Francisco, Rocha-Guzman, Nuria Elizabeth, Gallegos-Infante, Jose Alberto, Rivas-Arreola, Maria Jose, and Karchesy, Joseph J.
Abstract:: The most active phenolics in Quercus sideroxyla Humb. & Bonpl. residual bark were identified and evaluated following a chromatographic fractionation. Bark powder was defatted with hexane and crude extract (CE) was obtained by extraction with aqueous acetone (70%). A liquid partition with ethyl acetate was performed to produce an organic...

Epigenetic regulation of adaptive responses of forest tree species to the environment

Creator:: Braeutigam, Katharina, Vining, Kelly J., Lafon-Placette, Clement, Fossdal, Carl G., Mirouze, Marie, Gutierrez Marcos, Jose, Fluch, Silvia, Fernandez Fraga, Mario, Angeles Guevara, M., Abarca, Dolores, Johnsen, Oystein, Maury, Stephane, Strauss, Steven H., Campbell, Malcolm M., Rohde, Antje, Diaz-Sala, Carmen, and Cervera, Maria-Teresa
Abstract:: Epigenetic variation is likely to contribute to the phenotypic plasticity and adaptative capacity of plant species, and may be especially important for long-lived organisms with complex life cycles, including forest trees. Diverse environmental stresses and hybridization/polyploidization events can create reversible heritable epigenetic marks that can be transmitted to subsequent generations...

Lipid hydrolysis and oxidation development in frozen mackerel (Scomber scombrus): Effect of a high hydrostatic pressure pre-treatment

Creator:: Vázquez, Manuel, Torres, J. Antonio, Gallardo, José M., Saraiva, Jorge A., and Aubourg, Santiago P.
Abstract:: This work focused on assessing lipid damage during the storage of frozen Atlantic mackerel (Scomber scombrus) subjected to a high hydrostatic pressure (HHP) treatment (150, 300, 450 MPa with holding times of 0.0, 2.5, and 5.0 min) prior to freezing. The extent of lipid hydrolysis (free fatty acids) and oxidation...

Lipid damage inhibition by previous high pressure processing in frozen horse mackerel

Creator:: Torres, J. Antonio, Vázquez, Manuel, Saraiva, Jorge A., Gallardo, José M., and Aubourg, Santiago P.
Abstract:: This work focuses on the effect of a previous high pressure processing (HPP) on the lipid damage development occurring during the frozen storage (-10ºC; up to 3 months) of Atlantic horse mackerel (Trachurus trachurus). HPP conditions included different pressure (150, 300, 450 MPa) and pressure holding time (0.0, 2.5, 5.0...

Spatial Scale, Means and Gradients of Hydrographic Variables Define Pelagic Seascapes of Bluefin and Bullet Tuna Spawning Distribution

Creator:: Alvarez-Berastegui, Diego, Ciannelli, Lorenzo, Aparicio-Gonzalez, Alberto, Reglero, Patricia, Hidalgo, Manuel, López-Jurado, Jose L., Tintoré, Joaquín, and Alemany, Francisco
Abstract:: Seascape ecology is an emerging discipline focused on understanding how features of the marine habitat influence the spatial distribution of marine species. However, there is still a gap in the development of concepts and techniques for its application in the marine pelagic realm, where there are no clear boundaries delimitating...

Development of an improved extraction and HPLC method for the measurement of ascorbic acid in cows' milk from processing plants and retail outlets

Creator:: Chotyakul, Nattaporn, Pateiro-Moure, Miriam, Martínez-Carballo, Elena, Saraiva, Jorge Alexandre, Torres, José Antonio, and Pérez-Lamela, Concepción
Abstract:: An improved extraction (2.5% HPO₃, 5 mM dithiothreitol) and HPLC quantification using a C-18 column at 35°C and 0.1M acetic acid (98%) and acetonitrile (2%) mobile phase was developed to quantify total ascorbic acid (AA) in commercial whole/semi-skim/skim raw/pasteurized/UHT milk packaged in opaque bags, transparent plastic, cardboard, and Tetra Brik™....

Atypical presentation of pseudomembranous colitis localized in adenomatous polyps

Creator:: Hernández-Rocha, Cristian, Barra-Carrasco, Jonathan, Guzmán, Ana María, Paredes-Sabja, Daniel, Lezcano, Gabriel, Zoroquiaín, Pablo, and Álvarez-Lobos, Manuel
Abstract:: The most frequent cause of pseudomembranous colitis is Clostridium difficile (C. difficile) infection. This type of colitis is characterized by an endoscopic pattern of numerous small, yellowish or whitish plaques diffusely distributed, which typically compromises the rectum extending to proximal colon. Occasionally, the pseudomembranes compromise only the transverse or right...

Chemical and molecular characterization of fifteen species from the Lantana (Verbenaceae) genus

Creator:: de Sena Filho, Jose Guedes, Carregosa Rabbani, Allivia Rouse, dos Santos Silva, Tania Regina, Cruz da Silva, Ana Veruska, Souza, Igor Azevedo, Bryanne Araujo Santos, Maria Jose, de Jesus, Jemmyson Romario, de Lima Nogueira, Paulo Cesar, and Duringer, Jennifer M.
Abstract:: The essential oil from two Lantana species (Lantana lucida Schauer and Lantana salzmannii Schauer) were evaluated for their chemical composition by GC-MS. Results showed 17 predominant compounds for L. lucida, among which β-caryophyllene (19.0%) and α- caryophyllene (or humuleno, 33.0%) were the major components. L. salzmannii showed the presence of...

High-pressure Processing: Kinetic Models for Microbial and Enzyme Inactivation

Creator:: Serment-Moreno, Vinicio, Barbosa-Cánovas, Gustavo, Torres, José Antonio, and Welti-Chanes, Jorge
Abstract:: High pressure processing (HPP) has become the most widely accepted nonthermal food preservation technology. The pressure range for commercial processes is typically around 100-600 MPa, whereas moderate temperature (up to 65°C) may be used to increase microbial and enzymatic inactivation levels. However, these industrial processing conditions are insufficient to achieve...
