Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.

Evaluation de l’état de dégradation biologique des sols en matière organique dans la commune rurale de Kouka (Burkina Faso) [PDF]

open access: yesRevue Hybrides
La matière organique est primordiale pour la santé biologique, chimique et physique des sols. Son abondance dans le sol contribue à la fertilité, tandis que son absence est un signe majeur de la dégradation des sols.

Organic Donor–Acceptor–Donor Trimers Nanoparticles Stabilized by Amphiphilic Block Copolymers for Photocatalytic Generation of H2

open access: yesMacromolecular Rapid Communications, Volume 45, Issue 18, September 2024.
A versatile platform is developed for creating functional π‐conjugated organic nanoparticles stabilized by amphiphilic block copolymers for green H2 photocatalytic generation. The donor–acceptor–donor trimers nanoparticles show enhanced photocatalytic activity (≈0.6 mmol g⁻¹ h⁻¹) for H₂ production via water splitting. Abstract Photocatalytic generation

Impact of multilamellar formulations on stratum corneum lipid organization and epidermal lipid barrier enhancement (Part II)

open access: yesInternational Journal of Cosmetic Science, Volume 46, Issue 4, Page 578-589, August 2024.
The study shows the effectiveness of saturated phosphatidylcholine‐based multilamellar cream in restructuring the stratum corneum's lipid matrix in vivo. Through transmission electron microscopy, notable enhancements in lipid lamellae density and length are observed, along with a significant increase in key ceramides and free fatty acid levels ...

Aporte de las plantas de Eichhornia crassipes a la acumulacion de materiales organicos e inorganicos [PDF]

open access: yes, 1994
#Eichhornia crassipes$ est l'une des plantes les plus abondantes de la plaine d'inondation du fleuve Parana. Les détritus formés dans les îles flottantes s'accumulent à l'interface eau-sédiment ou bien dans le système racinaire des plantes.

The future of food safety: possible trends for the years 2022‐2032 and their influence on food safety and nutrition

open access: yesFood Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract Over the next decade, demographic, societal, technological, economic, environmental, and political factors are expected to significantly influence the agri‐food chain. Demographic shifts, characterised by an aging population and sustained migration, along with evolving consumer demands, will drive a greater emphasis on sustainability.
