La diabetes mellitus en la época y en la obra de Roberto Nóvoa Santos (1885-1933) : un análisis histórico-médico
(2011)
[Abstract] The modern epoch of diabetes began around 1674, with the publication of Thomas Willis’s Pharmaceutice Rationalis sive diatriba de Medicamentorum Operationibus in Humano Corpore. From then until 1921, the year ...
The linked units of 5S rDNA and U1 snDNA of razor shells (Mollusca: Bivalvia: Pharidae)
(Nature, 2011-08)
[Abstract] The linkage between 5S ribosomal DNA and other multigene families has been detected in many eukaryote lineages, but whether it provides any selective advantage remains unclear. In this work, we report the ...
Styrene removal from polluted air in one and two-liquid phase biotrickling filter: Steady and transient-state performance and pressure drop control
(Elsevier, 2011-07)
A Sporothrix variecibatus-inoculated biotrickling filter (BTF) was examined for styrene removal, without and with the addition of silicone oil, at different empty bed residence times. The highest elimination capacities ...
Biological conversion of carbon monoxide: rich syngas or waste gases to bioethanol
(Wiley-Blackwell, 2011)
Bioconversion of syngas/waste gas components to produce ethanol appears to be a promising alternative compared to the existing chemical techniques. Recently, several laboratory-scale studies have demonstrated the use of ...
Genetic heterogeneity in natural beds of the razor clam "Ensis siliqua" revealed by microsatellites
(Cambridge University Press, 2011-06-09)
[Abstract] The aim of this study was to analyse the genetic diversity and population structure in the razor clam Ensis siliqua along the European Atlantic coast taking into account their recent history of exploitation and ...
The 5S rDNA gene family in mollusks: characterization of transcriptional regulatory regions, prediction of secondary structures, and long-term evolution, with special attention to Mytilidae mussels
(Oxford University Press, 2011-07-01)
[Abstract] Several reports on the characterization of 5S ribosomal DNA (5S rDNA) in various animal groups have been published to date, but there is a lack of studies analyzing this gene family in a much broader context. ...
Molecular organization and phylogenetic analysis of 5S rDNA in crustaceans of the genus "Pollicipes" reveal birth-and-death evolution and strong purifying selection
(BioMed Central, 2011-10-17)
[Abstract]
Background: The 5S ribosomal DNA (5S rDNA) is organized in tandem arrays with repeat units that consist of a transcribing region (5S) and a variable nontranscribed spacer (NTS), in higher eukaryotes. Until ...
Friendly societies, commercial insurance and the state in sickness risk coverage: the case of Spain (1880-1944)
(Cambridge University Press, 2011-04)
[Abstract:]The main aim of this paper is to analyse the singularity of the Spanish position with regard to coverage of the risk of sickness within the context of the different welfare models described in international ...
