Bougainvillea Genus: A Review on Phytochemistry, Pharmacology, and Toxicology
Evidence-Based Complementary and Alternative Medicine, Volume 2018, Issue 1, 2018., 2018 This review discusses the current knowledge of the phytochemistry and in vitro and in vivo evaluations carried out using the extracts and, where appropriate, the main active components isolated from the genus Bougainvillea. Out of 18 species, most phytochemical, pharmacological, and toxicological studies focused on four species with different cultivars

Interseismic Megathrust Coupling at the Osa Peninsula, Costa Rica
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.Abstract At the Osa Peninsula in southern Costa Rica, magnitude >7 earthquakes have been generated along the Middle American trench in 1904, 1941, and 1983 following a ∼40‐year recurrence interval, suggesting a rupture may be impending. However, regional interseismic coupling remains poorly constrained, largely due to sparse observations that are ...

Oxidative Medicine and Cellular Longevity, Volume 2018, Issue 1, 2018., 2018 In the cerebral hypoxia‐ischemia rat model, the prophylactic administration of zinc can cause either cytotoxicity or preconditioning effect, whereas the therapeutic administration of selenium decreases the ischemic damage. Herein, we aimed to explore whether supplementation of low doses of prophylactic zinc and therapeutic selenium could protect from a

The 2021 La Palma eruption: social dilemmas resulting from life close to an active volcano
Geology Today, Volume 40, Issue 3, Page 96-111, May/June 2024.Damage and destruction caused by the 2021 eruption of the Tajogaite volcano on La Palma was unprecedented relative to other historical eruptions of the last century (1909, 1949, 1971, 2011) in the Canary Islands. The devastation caused by the eruption was not a result of eruption magnitude, which was only marginally larger than other historical events,

BioMed Research International, Volume 2017, Issue 1, 2017., 2017 Activation of macrophages may be one of the possible approaches in modulating inflammation. We previously reported that Bougainvillea xbuttiana extract showed an immunomodulatory activity. Here we compare the activation of macrophages exposed to B. xbuttiana extract and compare it with the other treatments such as LPS, IL‐4, and IL‐10.

Journal of Biogeography, Volume 51, Issue 2, Page 246-262, February 2024.Abstract Aim The poleward range expansion of tropical species, and range contraction of temperate species (known as tropicalisation) has mainly been studied from an ecological perspective, with little research on its genetic consequences. Here, we used distributional and genetic data to document the consequences of tropicalisation in rocky shore ...

Journal of Nanotechnology, Volume 2024, Issue 1, 2024.Silver nanoparticles (AgNPs) can be obtained from plants and other organisms through green synthesis methods, considered eco‐friendly and highly biocompatible. In this way, using plants with antitumor bioactive compounds increases cytotoxicity against tumor cells, acting in synergy between plant bioactive compounds (covering the nanoparticle) and AgNPs
