Proximity to metal mining is related to aspects of feather coloration but not fluctuating asymmetry in the Russet‐crowned Motmot (Momotus mexicanus) in south‐central Mexico

open access: yesIbis, Volume 165, Issue 2, Page 587-601, April 2023., 2023
Mining is present in all major biomes worldwide and overlaps strongly with areas of importance for bird conservation. Mining causes multiple types of environmental disturbance, including habitat alteration, increased human presence and persistent heavy metal pollution. Feather coloration and fluctuating asymmetry (random deviation from perfect symmetry

Evolution of fruit and seed traits during almond naturalization

open access: yesJournal of Ecology, Volume 110, Issue 3, Page 686-699, March 2022., 2022
Almond naturalization is consistent with strong directional selection on fruits and seeds, leading to smaller and more toxic seeds encased in harder endocarps. Accordingly, we propose that feralization of this crop is, at least to some degree, driven by adaptive evolution of dispersal and recruitment traits.

Reproductive colonization of land by frogs: Embryos and larvae excrete urea to avoid ammonia toxicity

open access: yesEcology and Evolution, Volume 12, Issue 2, February 2022., 2022
Frogs have evolved terrestrial eggs many times, offering an excellent opportunity to assess traits that may facilitate aquatic‐to‐terrestrial transitions. Our results suggest the importance of physiological adaptations and physiological plasticity during early life stages, specifically the early onset of urea excretion, its upregulation under dry ...

Cytotoxicity and effect on wound re‐epithelialization after topical administration of tranexamic acid

open access: yesBJS Open, Volume 3, Issue 6, Page 840-851, December 2019., 2019
Topical tranexamic acid reduces bleeding from surgical wounds, but little is known about possible adverse effects on the exposed tissue. In this experimental study, prolonged in vitro exposure was cytotoxic to keratinocytes and fibroblasts, and prevented wound re‐epithelialization in a dose‐dependent manner, whereas short exposure was well tolerated ...

Abarema cochliacarpos Extract Decreases the Inflammatory Process and Skeletal Muscle Injury Induced by Bothrops leucurus Venom

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
Snakebites are a public health problem, especially in tropical countries. However, treatment with antivenom has limited effectiveness against venoms’ local effects. Here, we investigated the ability of Abarema cochliacarpos hydroethanolic extract (EAc) to protect mice against injection of Bothrops leucurus venom.
