(AAAS, 2000)OBJECTIVE: To explore the role of the NF - kappaB/Rel transcription factor family in autoimmunity, we investigated whet her peripheral blood mononuclear cells (PBMC) and T cells from the blood of patients ...
-
(Springer, 2009-08-05)Iron is essential for crucial neuronal functions but is also highly toxic in excess. Neurons acquire iron through transferrin receptor-mediated endocytosis and via the divalent metal transporter 1 (DMT1). The N-terminus (1A, ...
-
(Oxford Univ Press, 2016)The expression of Dclcyb1 in tobacco induces a positive feedback on the isoprenoid, carotenoid, gibberellin and chlorophyll pathways leading to an enhancement in fitness, biomass, photosynthetic efficiency and carotenoid ...
-
(Ecological Society of America, 2017)© 2017 Fontúrbel et al. Anthropogenic disturbance can modify habitat structure and resource availability, potentially disrupting ecological interactions. This issue may be critical for pollination and seed dispersal, which ...
-
(MDPI, 2022)Several metals belong to a group of non-biodegradable inorganic constituents that, at low concentrations, play fundamental roles as essential micronutrients for the growth and development of plants. However, in high ...
-
(University of Chicago Press, 2017)Small resident bird species living at northern latitudes increase their metabolism in winter, and this is widely assumed to improve their chances of survival. However, the relationship between winter metabolic performance ...
-
(2002)Apparent competition occurs when species that otherwise may not directly interact still exhibit negative indirect effects on one another because they share a food-limited predator (enemy). Even though this type of indirect ...
-
(Wiley, 2014)Parasitic plants often have a strong fitness-impact on their plant hosts through increased host mortality and reduced or complete suppression of reproduction. Tristerix corymbosus (Loranthaceae) is a hemiparasitic mistletoe ...
-
(Taylor and Francis Ltd.michael.wagreich@univie.ac.at, 2020)
-
(Wiley, 2020)Adaptive explanations for the evolution of extra-pair paternity (EPP) suggest that females seek extra-pair copulations with high quality males. Still, the link between ornamentation, individual quality, and paternity remains ...
-
(2012)One of the greatest challenges for conservation biology is providing solutions for endangered species in modern landscapes, usually with deficient biological information on how species respond to landscape disturbances. ...
-
(Springer New York, 1999)Incubation of oat coleoptile segments with 40 μM indoleacetic acid (IAA) induced a decrease of 35-60% in peroxidase activity at the cell wall compartment. Treatment with IAA also produced a similar decrease in the oxidation ...
-
(2009)In nature, prey and predator species are embedded in complex networks of ecological interactions. As a consequence, organism level reactions such as predator-induced prey defenses will not only influence the dynamics of ...
-
(MDPI, 2021)Alzheimer's disease (AD) is the most common type of dementia in the elderly population. The disease is characterized by progressive memory loss, cerebral atrophy, extensive neuronal loss, synaptic alterations, brain ...
-
(Elsevier, 2020)In this work, cadmium telluride (CdTe) thin films were doped with Sn using a low-cost co-sublimation technique by a homemade close-spaced sublimation (CSS) system. Sn amount was calculated to obtain CdTe film doped with a ...
-
(American Chemical Society, 2017)The large surface-to-volume ratio of hollow palladium nanoparticles (hNPs) offers room to improve their hydrogen storage capacity as well as their catalytic activity. However, a less explored possibility is to use, in ...
-
(1979)The maturation of Xenopus laevis oocytes was studied in media free of added potassium salts. Under these conditions maturation could be triggered by 1 mM Mn2+ and La3+ and, to a lesser extent, by 2-4 mM Ca2+ and Mg2+. ...
-
(2013)The expression of defensive compounds derived from secondary metabolism in plants of Eucalyptus globulus Labill, and the persistence of these in vegetative propagation was evaluated by gas chromatography with flame ionization ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2008-02)Plant traits may play multiple functional roles simultaneously. Leaf trichomes have been related to resistance against herbivores as well as to enhanced water economy in the plant. In a greenhouse study, we evaluated the ...
