-
(2012)The kelp Lessonia nigrescens Bory is the most ecologically and economically important seaweed in rocky intertidal and shallow subtidal habitats along the temperate Pacific South American coasts. Recent molecular studies ...
-
(ELSEVIER, 2008-11)During the past few decades the microbial bioleaching of metallic sulphide ores has become a very important process utilized by the mining industry. The biodiversity studies of industrial systems have revealed the occurrence ...
-
(2013)Based on recent advances in ecological network theory, we present an ad hoc conceptual framework and a methodological proposal for the evaluation of the ecological relevance of species within a community, oriented towards ...
-
(2006)Two fully automated HPLC-NMR methods are reported and compared for the structure elucidation of four isomeric tropane alkaloids from the stem-bark of an endemic Chilean plant, Schizanthus grahamii Gill. (Solanaceae). The ...
-
(Frontiers Media S.A., 2016)Microcin E492 (MccE492) is a pore-forming bacteriocin produced and exported by Klebsiella pneumoniae RYC492. Besides its antibacterial activity, excreted MccE492 can form amyloid fibrils in vivo as well as in vitro. It has ...
-
(2004)In recent years, research on neural crest induction has allowed the identification of several molecules as candidates for neural crest inducers. Although many of these molecules have the ability to induce neural crest in ...
-
(MDPI, 2020)The family of paramyxoviruses has received growing attention as several new species have been identified recently, notably two different clusters in domestic cats, designated as feline morbillivirus (FeMV) and feline ...
-
(SPRINGER, 2010-03-07)We isolated and characterised six novel microsatellite loci for paternity analysis in the sand martin Riparia riparia, by screening an enriched genomic library. In addition, we tested 16 already published microsatelli ...
-
(2002)Endemic taxa are those restricted to a specific area, and could be defined as the exclusive biodiversity of a region. An area of endemism contains taxa found nowhere else and could be catalogued as irreplaceable and of ...
-
(Elsevier, 2013)Cervical vertebrae of elasmosaurids (Sauropterygia, Plesiosauroidea) have proven to be informative even at family level. The present paper uses a previously developed methodology based on bivariate graphic analysis that ...
-
(1997)In Drosophila the decision processes between the neural and epidermal fate for equipotent ectodermal cells depend on the activity of proneural genes. Members of the Drosophila Iroquois-Complex (Iro-C) positively regulate ...
-
(WILEY-LISS, 2008-06-20)Oligodendrocytes form an insulating multilamellar structure of compact myelin around axons, which allows efficient and rapid propagation of action potentials. However, little is known about the molecular mechanisms ...
-
(ACS Publications, 2015)Enzyme-substrate binding is a dynamic process intimately coupled to protein structural changes, which in turn changes the unfolding energy landscape. By the use of single-molecule force spectroscopy (SMFS), we characterize ...
-
(1976)A past history of idiopathic cholestasis of pregnancy (ICP) was detected in 10 out of the 32 multiparous women in the last two generations of a large kindred. The affected women are distributed in five family units, sharing ...
-
(1979)For the construction of a phylogenetic tree an algorithm is described. This, allows the correction of the original data and the proper selection, in each step of the process, of the nearest neighbours of a common ancestor. ...
-
(Elsevier, 2017)Light stimulates the biosynthesis of carotenoids and regulates the development of plastid structures to accommodate these photoprotective pigments. Work with Arabidopsis revealed molecular factors coordinating carotenoid ...
-
(BMC, 2021)Draft genomes of Penicillium roqueforti, Fusarium sororula, Chalaropsis populi, and Chrysoporthe puriensis are presented. Penicillium roqueforti is a model fungus for genetics, physiological and metabolic studies, as well ...
