(2012)Many intertidal rocky habitats of the Chilean coast were dominated by the dark green thalli of a mat-forming Codium. This green seaweed was ecologically important because it formed a permanent belt by coalescence between ...
-
(1989)The description of the optimized evolution of a code based on 4 nucleotides involves a sequential transition of codons, formed firstly by monomers evolving to dimers and then to triplets, in accordance with the progressive ...
-
(BioMed Central, 2015)Background Synonymous codons are used differentially in organisms from the three domains of life, a phenomenon referred to as codon usage bias. In addition, codon pair bias, particularly in the 3’ codon context, has also ...
-
(Public Library Science, 2018-05-09)The analysis of codon usage bias has been widely used to characterize different communities of microorganisms. In this context, the aim of this work was to study the codon usage bias in a natural consortium of five acidophilic ...

Coerulear activation by CRH and its role in hypertension induced by prenatal malnutrition in the rat (TAYLOR & FRANCIS LTD, 2007-05)The effects of intracoerulear CRH and intraparaventricular prazosin on systolic pressure, diastolic pressure and heart rate were studied in prenatally malnourished hypertensive rats. At day 40 of life, (i) malnourished ...

(NATL ACAD SCIENCES, 2003-11-25)Glutamyl-tRNA synthetases (GluRSs) occur in two types, the discriminating and the nondiscriminating enzymes. They differ in their choice of substrates and use either tRNA(Glu) or both tRNA(Glu) and tRNA(Gln). Although most ...
-
(ELSEVIER, 2006-07)Simple patch-occupancy models of competitive metacommunities have shown that coexistence is possible as long as there is a competition-colonization tradeoff such as that of superior competitors and dispersers. In this ...
-
(2007)The mechanical behavior of a supersolid is studied in the framework of a fully explicit model derived from the Gross-Pitaevskii equation without assuming any defect or vacancy. A set of coupled nonlinear partial differential ...
-
(2007)Epidemiologic evidence suggests a preferential association of Trypanosoma cruzi genotypes TCI and TCII with marsupials and placental mammals, respectively. We identify T. cruzi genotypes from 117 infected mammals. Minicircle ...
