(Taylor & Francis, 2016)Cheilodactylus variegatus is a common benthivorous marine fish inhabiting in rocky subtidal habitats in the eastern south Pacific coast of Chile and Peru. However, its biology and ecology are relatively understudied and ...
-
(Academic Press Inc., 2000)The organization of the cytoskeleton in the early first interphase zygote and its involvement in organelle redistribution were studied in the glossiphoniid leech Theromyzon trizonare by confocal and electron microscopy, ...
-
(Life Science Alliance, 2022)Actin filament polymerization can be branched or linear, which depends on the associated regulatory proteins. Competition for actin monomers occurs between proteins that induce branched or linear actin polymerization. ...
-
(1996)A method to construct Hamiltonian theories for systems of both ordinary and partial differential equations is presented. The knowledge of a Lagrangian is not at all necessary to achieve the result. The only ingredients ...
-
(American Physiological Society, 2021)The rise of microscopy in the seventeenth century allowed scientists to discover a new world of microorganisms and achieve great physiological advances. One of the first microscopes of the epoch was Antonie van Leeuwenhoek's ...

(1998)We describe the current state of the ruil (Nothofagus alessandrii) forest, a rare and endemic temperate forest in central Chile. Because of a long history of land-use, the ruil forest has suffered intense deforestation and ...
-
(Elsevier, 2020)This paper reviews current understanding of deglaciation in North, Central and South America from the Last Glacial Maximum to the beginning of the Holocene. Together with paleoclimatic and paleoceanographic data, we compare ...
-
(Nature, 2021)Dendritic cells (DCs) promote T-cell mediated tolerance to self-antigens and induce inflammation to innocuous-antigens. This dual potential makes DCs fundamental players in inflammatory disorders. Evidence from inflammatory ...
-
(Oxford University Press, 2018)While Chandrasekhar-mass (MCh) models with a low 56Ni yield can match the peak lumi- nosities of fast-declining, 91bg-like Type Ia supernovae (SNe Ia), they systematically fail to reproduce their faster light-curve evolution. ...
-
(Elsevier Ltd., 2011-10-06)Two fluorescence probes for the detection of cysteine (Cys), glutathione (GSH) and other biothiols, such as homocysteine (Hcy) and cysteinyl-glycine (Cys-Gly), were developed. These molecular probes are coumarin-based ...

The developmental origin of zygodactyls feet and its possible loss in the evolution of passeriformes (Royal Society, 2014)The zygodactyl orientation of toes (digits II and III pointing forwards, digits I and IV pointing backwards) evolved independently in different extant bird taxa. To understand the origin of this trait in modern birds, we ...

(1993)Abstract— The disposition of nifurtimox was studied in the rat isolated perfused liver using a recirculating system. The drug was administered as a bolus (5·0, 15·0 or 30·0 μg mL−1), and its disappearance was monitored by ...
