Chapter 1.4 Antarctic volcanism: active volcanism overview

Geological Society, London, Memoirs, 2021
Abstract In the last two centuries, demographic expansion and extensive urbanization of volcanic areas have increased the exposure of our society to volcanic hazards. Antarctica is no exception. During the last decades, the permanent settlement and seasonal presence of scientists, technicians, tourists and logistical personnel close to active

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 ...

Prophylactic Zinc and Therapeutic Selenium Administration Increases the Antioxidant Enzyme Activity in the Rat Temporoparietal Cortex and Improves Memory after a Transient Hypoxia‐Ischemia

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

Los volcanes y los hombres [PDF]

, 2007
Desde las entrañas de la tierra, los volcanes han creado la atmósfera, el agua de los océanos, y esculpido los relieves del planeta: son, pues, los zahoríes de la vida. Existen volcanes que los hombres explotan o cultivan, y otros sobre los cuales se han

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,

Comparison between Peritoneal Macrophage Activation by Bougainvillea xbuttiana Extract and LPS and/or Interleukins

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.
