Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Dossier : actualités en reproduction équine

, 1999
La production par une jument d’un poulain par an (et pourquoi pas de plusieurs) avec de la semence d’étalon conservée fraîche ou congelée est l’objectif appliqué actuel de toutes les équipes de recherche.

Les variations saisonnières des performances de reproduction chez la truie

INRAE Productions Animales, 2005
Bien que la truie ne connaisse pas d’anœstrus saisonnier, une diminution des performances de reproduction est observée en été et au début de l’automne dans de nombreux pays. La proportion de truies qui tardent à revenir en oestrus après le tarissement augmente tandis que la proportion de truies inséminées qui mettent bas baisse de 5 à 15 %.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Biological management of the high density black rhino population in Solio Game Reserve, central Kenya

Pachyderm, 2008
Optimising breeding performance in a seriously endangered species such as the black rhinoceros (Diceros bicornis) is essential. Following an estimation of the population demography of the black rhinos in Solio Game Reserve, Kenya and a habitat ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

High-fidelity colour reproduction for high-dynamic-range imaging [PDF]

, 2010
The aim of this thesis is to develop a colour reproduction system for high-dynamic-range (HDR) imaging. Classical colour reproduction systems fail to reproduce HDR images because current characterisation methods and colour appearance models fail to ...
