Antiprotozoal activity of flavonoids from Eupatorium arnottianum [PDF]

open access: yes, 2017
Dichloromethane and ethanol extracts of Eupatorium arnottianum were evaluated for invitroleishmanicidal activity. The dichloromethane extract produced 80% and 85% of growthinhibition on both Leishmania mexicana and Leishmania amazonensis promastigotes ...

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Reversal of Multidrug Resistance in Cancer by Multi-Functional Flavonoids

open access: yesFrontiers in Oncology, 2019
Multidrug resistance (MDR) resulting from different defensive mechanisms in cancer is one of the major obstacles of clinical treatment. To circumvent MDR many reversal agents have been developed, but most of them fail in clinical trials due to severely ...

Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

Bioavailability and Metabolism of Flavonoids: A Review [PDF]

open access: yesInternational Journal of Nutrition Sciences, 2017
Flavonoids are a group of plant antioxidants that are widely distributed in plants from the root and stem to the leaves, flowers, and fruits. They are generally present as glycosides, conjugated to sugars, although their aglycone forms may also exist ...

Dietary flavonoids of Spanish youth: intakes, sources, and association with the Mediterranean diet [PDF]

open access: yesPeerJ, 2017
Background Plant-based diets have been linked to high diet quality and reduced risk of cardiovascular diseases. The health impact of plant-based diets might be partially explained by the concomitant intake of flavonoids.

Mapping the Cerebral Organoid Landscape: A Systematic Review of Preclinical 3D Models in Neuroscience

open access: yesAdvanced Healthcare Materials, EarlyView.
Cerebral organoids are transforming brain research, yet the field remains fragmented. This comprehensive systematic review maps 738 studies published between 2014 and 2024 to uncover trends, gaps, and opportunities across neuroscience. Introducing OrganoidMap—an interactive, open‐access platform to explore and compare models—this work enables ...

Analysis of the Flavonoidome Reveals the Different Health-Promoting Flavonoid Characteristics in Fruit

open access: yesAntioxidants, 2023
Flavonoids are one of the important metabolites of plants, and many flavonoids have functions of antioxidant or antimicrobial, which can help plants resist environmental stress. On the other hand, flavonoids also have a health-promoting effect for humans,
