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 ...

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.

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 ...

Characterization of raw and thermochemically-treated mesocarp fibers of Oenocarpus bataua, an Amazon palm

CERNE, 2023
Background: Patauá (Oenocarpus bataua Mart.) is a palm tree belonging to the botanical family Arecaceae that occurs throughout the Amazon. Like açaí, an edible pulp is extracted from its fruits, remaining a fiber-rich waste. Revealing the potential of such raw or thermochemically modified fibers for producing bioproducts is a novelty in the literature.
