Retos en el estudio de membranas biológicas usando simulaciones de dinámica molecular

Epistemus
En el estudio de simulaciones de membrana modelo, la selección de componentes resulta crucial. Incluso al considerar solo la bicapa, núcleo esencial de la membrana, distintos lípidos generan variadas interacciones, influyendo en el comportamiento del ...

Genetic Ancestry Reveals Historical Diversity of Formation Across Three Brazilian Communities of African Descent (Quilombos) in Central Brazil

American Journal of Human Biology, Volume 38, Issue 1, January 2026.
ABSTRACT Introduction Characterized as relatively isolated communities, many Brazilian quilombos were formed during the period of slavery in Brazil when enslaved persons (most of African descent) ran away or were abandoned by their enslavers. Quilombos in Central Brazil, whose settlement was more recent due to the relative isolation of the region ...

Mucoadhesive Polyvinyl Alcohol Film Containing Fridericia chica Extract for Mucositis Treatment: Pharmacological Evaluation and Active Compounds Release

Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.
ABSTRACT Oral mucositis is a frequent and painful complication of cancer therapy with limited effective options. This study evaluated a mucoadhesive polyvinyl alcohol (PVA) film containing 2.5% Fridericia chica extract as a novel strategy. The formulation was characterized for antioxidant activity, phenolic and flavonoid content, and reactive species ...
