Intestinal epithelia (Caco-2) cells acquire iron through the basolateral endocytosis of transferrin (1996)Although the absorption of iron through the intestinal epithelia is inversely related to body iron stores, the mechanisms by which the enterocytes sense body iron stores are unknown. Polarized enterocytes have transferrin ...
-
(MDPI, 2021)Land-use changes are one of the most important drivers of zoonotic disease risk in humans, including helminths of wildlife origin. In this paper, we investigated the presence and prevalence of intestinal helminths in wild ...

(2002)Allometry of haematological parameters (haematocrit, erythrocyte number, mean cell volume and haemoglobin concentration) of Basilichthys australis, suggested that small individuals and juveniles had larger red blood cells, ...
-
(Kluwer Academic/Plenum Publishers, 1999)Experimental tests were conducted to determine whether females and males of the tree-dwelling lizard Liolaemus tenuis (Tropiduridae) show intraspecific chemical recognition during breeding and postreproductive seasons. ...

(Sociedad de Biologia de Chile, 2005)Studies of metabolic capacities in rodents have been largely studied at an inter-specific levels, but physiological capacities of populations belonging to the same species have received lesser attention. Here we studied ...
-
(Springer, 2018)Populations of the same species can vary substantially in their behavioral and morphometric traits when they are subject to different environmental pressures, which may lead to the development of different adaptive strategies. ...

(ROCKEFELLER UNIV PRESS, 2008-02)The internal vestibule of large-conductance Ca2+ voltage-activated K+ (BK) channels contains a ring of eight negative charges not present in K+ channels of lower conductance (Glu386 and Glu389 in hSlo) that modulates channel ...
-
(Oxford University Press, 2016)Definition of lichens has evolved from bi(tri)partite associations to multi-species symbioses, where bacteria would play essential roles. Besides, although soil bacterial communities are known to be affected by edaphic ...

(Elsevier, 2010-09-29)We herein demonstrate that the global electrophilicity may be distributed into fragments within a single molecule by using an empirical partitioning scheme of the electronic chemical potential framed on the chemical ...
-
(Regional Euro-Asian Biological Invasions Centre-Reabic, 2020)There is scarce documentation of the presence of trout in the Puna and southern Altiplano in Chile, in spite of the risk that they represent for these ecosystems of high environmental value, which have endemic and highly ...
-
(Royal Botanical Society of Belgium, 2016)Background and aims - Once introduced into new regions, exotic species often experience shifts in resource allocation in response to the different environmental conditions found in the introduction range. Plants naturally ...
