Evaluation of a compounding phospholipid base for the percutaneous absorption of high molecular weight drugs using the Franz finite dose model.

Skin Res Technol
Abstract Background Permeation‐enhancing compounding bases are aimed to facilitate the penetration of the active pharmaceutical ingredients (APIs) across the skin barrier. Objectives The purpose of this study was to evaluate the percutaneous absorption of radiolabeled human insulin (14C‐isototpe) when incorporated in a proprietary phospholipid base ...

The fate and transit time of carbon in a tropical forest

Journal of Ecology, Volume 109, Issue 8, Page 2845-2855, August 2021., 2021
The transit time distribution quantifies the time it takes for photosynthates to appear in the respiration flux. For a tropical forest in Colombia, it predicts that 50% of fixed carbon is respired in <0.5 years, and 95% in <69 years. Editor's Choice Abstract Tropical forests fix large quantities of carbon from the atmosphere every year; however, the ...

Pleistocene climatic fluctuations promoted alternative evolutionary histories in Phytelephas aequatorialis, an endemic palm from western Ecuador

Journal of Biogeography, Volume 48, Issue 5, Page 1023-1037, May 2021., 2021
Abstract Aim Pleistocene (2.58 Ma–11.7 ka) climatic fluctuations have shaped intraspecific genetic patterns worldwide; however, their impact on species in many regions remains unknown. In order to determine the impact of Pleistocene climatic fluctuations on the tropical rain forests of western Ecuador, we explored the evolutionary history of the ...

Pollination ecology in the tropical Andes: moving towards a cross-scale approach. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Defaunation Increases Clustering and Fine-Scale Spatial Genetic Structure in a Small-Seeded Palm Despite Remaining Small-Bodied Frugivores. [PDF]

Mol Ecol
ABSTRACT Anthropogenic pressures such as hunting are increasingly driving the localised functional extinctions of large‐ and medium‐sized wildlife in tropical forests, a phenomenon broadly termed ‘defaunation’. Concurrently in these areas, smaller‐bodied species benefit from factors such as competitive release and increase in numbers.
