Permeability of 16 Straight- and Branched-Chain Parabens Using the Caco-2 Assay. [PDF]

open access: yesJ Appl Toxicol
ABSTRACT The in vitro intestinal permeability of straight‐ and branched‐chain parabens has not been extensively investigated. Sixteen parabens were tested in the Caco‐2 assay. Passive diffusion was measured using PAMPA. The transport of the MCT1 substrate, p‐coumaric acid, as well as propylparaben and isopropylparaben, was investigated.

Preliminary Appraisal of a Correlation Between Glaciations and Large Igneous Provinces Over the Past 720 Million Years

open access: yesGeophysical Monograph Series, Page 169-190., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Rainfall extremes modeling under shortage of data and uncertainty in the Pampean region (Argentina)

open access: yesCuadernos de Investigación Geográfica, 2018
The assessment of the surface runoff capacity of storms is essential for the design of drainage infrastructure, for the management of rainfall excesses and the control of soil erosion. The knowledge of precipitation intensity values at scales larger than

Glyphosate and AMPA concentrations in wind-blown material under field conditions [PDF]

open access: yes, 2018
Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle-farming country, which has increased its productivity in the last few ...

The fluctuating resource hypothesis explains invasibility, but not exotic advantage following disturbance [PDF]

open access: yes, 2018
Invasibility is a key indicator of community susceptibility to changes in structure and function. The fluctuating resource hypothesis (FRH) postulates that invasibility is an emergent community property, a manifestation of multiple processes that cannot ...

Are Local Filters Blind to Provenance? Ant Seed Predation Suppresses Exotic Plants More than Natives [PDF]

open access: yes, 2014
The question of whether species’ origins influence invasion outcomes has been a point of substantial debate in invasion ecology. Theoretically, colonization outcomes can be predicted based on how species’ traits interact with community filters, a process
