The Cardiovascular Protective Function of Natural Compounds Through AMPK/SIRT1/PGC‐1α Signaling Pathway

open access: yesFood Science &Nutrition, Volume 12, Issue 12, Page 9998-10009, December 2024.
Cardiovascular disease (CVD) is a major threat to human health and imposes a heavy burden on individuals, society, and healthcare systems. A key goal of our search was to find natural compounds that target this biological pathway and have beneficial effects on CVD.

Demixing and orientational ordering in mixtures of rectangular particles [PDF]

open access: yes, 2007
Using scaled-particle theory for binary mixtures of two-dimensional hard particles with rotational freedom, we analyse the stability of nematic phases and the demixing phase behaviour of a variety of mixtures, focussing on cases where at least one of the

O epitélio respiratório em ratos Wistar

open access: yesRevista Portuguesa de Pneumologia, 2003
ABSTRACTMorphofunctional changes of respiratory epithelia became the object of intense study in Wistar rats after previous research showed that occupationally-simulated exposure to low frequency noise (≤500Hz, including infrasound) induced irreversible lesions in these tissues.

Killer Whale Predation on a Giant Manta Ray (Mobula birostris), a Sicklefin Devil Ray (Mobula tarapacana) and a Tiger Shark (Galeocerdo cuvier) in the Southwest Indian Ocean

open access: yesAfrican Journal of Ecology, Volume 62, Issue 4, December 2024.
ABSTRACT Knowledge of killer whale (Orcinus orca) feeding ecology in tropical waters is scarce. In the southwest Indian Ocean, opportunistic sightings provide a valuable source of information to better understand their behaviour, diet and distribution. Here, we compile existing records of killer whale predation on elasmobranchs in the southwest Indian ...

Prioritizing Conservation Areas for the Hyacinth Macaw (Anodorhynchus hyacinthinus) in Brazil From Low‐Coverage Genomic Data

open access: yesEvolutionary Applications, Volume 17, Issue 11, November 2024.
ABSTRACT Estimates of current genetic diversity and population connectivity are especially important for endangered species that are subject to illegal harvesting and trafficking. Genetic monitoring can also ensure that management units are sustaining viable populations, while estimating genetic structure and population dynamics can influence genetic ...
