Effect of diet on the capacity to remove mercury from the body of a penguin (Spheniscus demersus) living in the ZOO

open access: yesE3S Web of Conferences, 2013
Birds due to its position in the trophic chain are good monitors of the marine environment in terms of mercury contamination. For the proper interpretation of results it is necessary to know both the processes of accumulation of this metal in their ...

Bio‐Inspired Biopolymeric Implantable Platform for Localized and Sustained Drug Delivery in Solid Tumor Treatment

open access: yesAdvanced Functional Materials, EarlyView.
A bio‐inspired biopolymeric implantable drug delivery platform enables localized and sustained release of 7‐ethyl‐10‐hydroxycamptothecin (SN‐38) in solid tumor treatment. The three‐dimensional (3D) structured crosslinked‐chitosan implants are fabricated via 3D‐printed molds and provide drug release over 3 months, significantly inhibiting tumor growth ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

open access: yesAdvanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Volières féminines

open access: yesImages Re-Vues
The notion of the “human zoo”, which has met with great success, appears problematic for a number of reasons, starting with the indistinctness of the processes of animalization it proposes to bring together.

DNA Isolation of Chicken Feathers from the Base of the Young Feathers, the Base of the Old Feathers, and the Tip of the Feathers

open access: yesBIOEDUSCIENCE, 2021
Background:  The goal was to provide information on the use of DNA templates in chicken samples so that the molecular research sampling process may employ feathers instead of hurting the test animals. Method: The sample used consisted of 10 Bangkok chickens which were sampled for young feathers and old feathers and the tips of the feathers ...
