Swelling-activated ion channels: functional regulation in cell-swelling, proliferation and apoptosis
(BLACKWELL, 2006-06)
Cell volume regulation is one of the most fundamental homeostatic mechanisms and essential for normal cellular function. At the same time, however, many physiological mechanisms are associated with regulatory changes in ...
Morpho-histochemical characterization of salivary gland cells of males of the tick Rhipicephalus sanguineus (Acari: Ixodidae) at different feeding stages: description of new cell types
(Springer, 2010-01-01)
This study describes the changes undergone by cells of the salivary glands of unfed and feeding (at day two and four post-attachment) Rhipicephalus sanguineus males, as well as new cell types. In unfed males, types I and ...
Catalytic activity vs. size correlation in platinum catalysts of PEM fuel cells prepared on carbon black by different methods
(Pergamon-Elsevier Science Ltd, 2009-10)
In this work nanoparticulated platinum catalysts have been prepared on carbon Vulcan XC-72 using three methods starting with chloroplatinic acid as a precursor: (i) formic acid as a reductor agent; (ii) impregnation method ...
Effect of the relationship between particle size, inter-particle distance, and metal loading of carbon supported fuel cell catalysts on their catalytic activity
(SPRINGERDORDRECHT, 2012)
The effect of the relationship between particle size (d), inter-particle distance (x(i)), and metal loading (y) of carbon supported fuel cell Pt or PtRu catalysts on their catalytic activity, based on the optimum d (2.5-3 ...
Morphological Features of the Apical Region in the Principal Cells of Mongrel Dog Epididymis
(Soc Chilena Anatomia, 2008-03-01)
The epithelial principal cells are the predominant cell type of the epididymis. These cells have been shown to be both secretory and endocytic cells. The apical region of the cytoplasm of principal cells in the mongrel dog ...

Pulmonary hematological parameters, energetic flight demands and their correlation with oxygen diffusion capacity in the lungs
(Sociedad de Biologia de Chile, 2007)
Hematological parameters of birds and mammals seem to respond to environmental requirements, such as hypoxia at high altitude and the energetic demands of locomotion and flight. In this work we hypothesize that lung capillary ...
