The bryophyte flora of Lågskär - An isolated island in the Baltic Sea

2014

This study reports the bryophyte flora of Lågskär, an isolated lighthouse island in the Åland province of Finland. A total of 81 bryophyte species were found on Lågskär, including 74 moss species and seven liverwort species. Syntrichia ruraliformis is reported for the first time in Finland, whereas Ceratodon conicus was believed to be extinct in Finland and Brachythecium turgidum was considered regionally extinct from southern Finland. peerReviewed

Systems of quasilinear elliptic equations with dependence on the gradient via subsolution-supersolution method

2017

For the homogeneous Dirichlet problem involving a system of equations driven by \begin{document}$(p,q)$\end{document} -Laplacian operators and general gradient dependence we prove the existence of solutions in the ordered rectangle determined by a subsolution-supersolution. This extends the preceding results based on the method of subsolution-supersolution for systems of elliptic equations. Positive and negative solutions are obtained.

Reëvaluation of Orthotrichum Rhytiore (Orthotrichaceae)

2008

Examination of the holotype of Orthotrichum rhytiore B. H. Allen reveals gametophytic characters which support the placement of the species in Ulota. The species is peculiar within the genus due to its unusual sporophyte morphology, and the occurrence of these sporophytic characters in Ulota is discussed. Ulota rhytiore (B. H. Allen) F. Lara, Garilleti, Albertos & Mazimpaka comb. nov. is the first known species of the genus in tropical America.

Modular organization in the reductive evolution of protein-protein interaction networks

2006

Analysis of the reduction in genome size of Buchnera aphidicola from its common ancestor E. coli shows that the organization of networks into modules is the property that seems to be directly related with the evolutionary process of genome reduction.

Unexpected Modulation of Recall B and T Cell Responses after Immunization with Rotavirus-like Particles in the Presence of LT-R192G

2010

LT-R192G, a mutant of the thermolabile enterotoxin of E. coli, is a potent adjuvant of immunization. Immune responses are generally analyzed at the end of protocols including at least 2 administrations, but rarely after a prime. To investigate this point, we compared B and T cell responses in mice after one and two intrarectal immunizations with 2/6 rotavirus-like particles (2/6-VLP) and LT-R192G. After a boost, we found, an unexpected lower B cell expansion measured by flow cytometry, despite a secondary antibody response. We then analyzed CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs) and CD4(+)CD25(+)Foxp3(-) helper T cells after in vitro (re)stimulation of mesenteric lymph node cells …

Recombinant expression, in vitro refolding, and biophysical characterization of the N-terminal domain of T1R3 taste receptor

2012

Facteur d'impact (5 ans) : 1,617Notoriété à 2 ans : Acceptable (biochem.res.methods); The sweet taste receptor is a heterodimeric receptor composed of the T1R2 and T1R3 subunits, while T1R1 and T1R3 assemble to form the umami taste receptor. T1R receptors belong to the family of class C G-protein coupled receptors (GPCRs). In addition to a transmembrane heptahelical domain, class C GPCRs have a large extracellular N-terminal domain (NTD), which is the primary ligand-binding site. The T1R2 and T1R1 subunits have been shown to be responsible for ligand binding, via their NTDs. However, little is known about the contribution of T1R3-NTD to receptor functions. To enable biophysical characteriza…
