Paleogene Land Mammal Faunas of South America; a response to global climatic changes and indigenous floral diversity
(Springer, 2014-02)
An appraisal of Paleogene floral and land mammal faunal dynamics in South America suggests that both biotic elements responded at rate and extent generally comparable to that portrayed by the global climate pattern of the ...
Description of self-diffusion coefficients of gases, liquids and fluids at high pressure based on molecular simulation data
(Elsevier Science, 2006-04)
The purpose of this work is to evaluate the potential of modeling the self-diffusion coefficient (SDC) of real fluids in all fluid states based on Lennard-Jones analytical relationships involving the SDC, the temperature, ...
Differential transcriptional responses underlie dietary induction of intestinal carbohydrase activities in house sparrow nestlings
(Wiley, 2015-06)
Many species show diet-induced flexibility of activity of intestinal enzymes; however, molecular and genetic mechanisms responsible for such modulation are less known, particularly in altricial birds. The goal of our study ...
Increased Stability and Breakdown of Brain Effective Connectivity during Slow-Wave Sleep: Mechanistic Insights from Whole-Brain Computational Modelling
(Nature Publishing Group, 2017-12)
Recent research has found that the human sleep cycle is characterised by changes in spatiotemporal patterns of brain activity. Yet, we are still missing a mechanistic explanation of the local neuronal dynamics underlying ...
Composition of the Lower Cretaceous source rock from the Austral Basin (Río Mayer Formation, Patagonia, Argentina): Regional implication for unconventional reservoirs in the Southern Andes
(Elsevier, 2015-09)
The importance of the Río Mayer Formation (Lower Cretaceous, prodelta to marine outer shelf) in the hydrocarbon development of the Austral Basin (Patagonia, Argentina) has been recognized by several authors. This unit plays ...
Biological affinities and regional microevolution among pre-Hispanic communities of Colombia's Northern Andes
(E. Schweizerbart'sche Verlagsbuchhandlung, 2015-05)
Dental non-metric data were used to examine the biological continuity of pre- Hispanic peoples of Colombia's Northern Andes, including highland, lowland and coastal peoples. This report contributes to studies regarding the ...
Reduced cardio-respiratory coupling indicates suppression of vagal activity in healthy relatives of patients with schizophrenia
(Elsevier Inc, 2010-03)
Previous studies have observed reduced vagal modulation in patients with acute schizophrenia and their first-degree relatives, thus suggesting a genetic predisposition. To investigate vagal modulation, we analyzed the ...
Neurotoxic impact of mercury on the central nervous system evaluated by neuropsychological tests and on the autonomic nervous system evaluated by dynamic pupillometry
(Elsevier Science Bv, 2017)
Mercury vapor is highly toxic to the human body. The present study aimed to investigate the occurrence of neuropsychological dysfunction in former workers of fluorescent lamps factories that were exposed to mercury vapor ...
