The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...

Palladium–mediated organofluorine chemistry [PDF]

open access: yes, 2014
Producción CientíficaThe substitution of fluorine for hydrogen in a molecule may result in profound changes in its properties and behaviour. Fluorine does not introduce special steric constraints since the F atom has a small size. However, the changes in

Biological studies of organotin(IV) complexes with 2-mercaptopyrimidine

open access: yesRussian Chemical Bulletin, 2007
The known organotin(IV) complexes with 2-mercaptopyrimidine (L) [Me2SnL2] (1), [Bun 2SnL2] (2), [Ph2SnL2] (3), and [Ph3SnL] (4) were synthesized using a new approach. The effect of the synthesized compounds on peroxidation of fatty acids (oleic and linoleic) was studied. Complexes 1–4 promote the peroxidation of oleic acid. Their effect

Care Pathways and Determinants in Essure® Contraceptive Implant Use and Removal: A Qualitative Study

open access: yesHealth Expectations, Volume 29, Issue 2, April 2026.
ABSTRACT Background Introduced in 2002, the Essure® implant was promoted as a minimally invasive permanent contraceptive. After widespread use, increasing reports of adverse effects led to its global withdrawal in 2018. This study explores the experiences of women in France who chose Essure®, focusing on their motivations and the factors leading to its
