Taxonomie des connaissances en conception préliminaire [PDF]

open access: yes, 2009
La conception est l’activité de transformation d’exigences fonctionnelles en paramètres de conception. Notre article présente une méthode de structuration du problème de conception exploitant des connaissances déjà ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Using GnRH to Improve Cow Fecundity after Calving

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
At dairy cows, the increase in milk production is associated with the decrease of heat manifestation and conception rates. GnRH is mostly used for treatment of different problems of the reproductive function and for improving the pregnancy rates in cows.

The influence of season and sire on the results of superovulation and embryo transfer

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2006
The aim of the study was evaluate the influence of season and sires on profit and quality of embryos after superovulated treatment. Next we evaluated the conception rate after transfer of fresh and frozen embryos.In 1991–2004 there were used the beef ...

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

open access: yesFEBS 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.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Diversity and complexity in neural organoids

open access: yesFEBS 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.

RACING STRESS AND CONCEPTION RATE IN REPEAT BREEDING BUFFALOES AND COWS [PDF]

open access: yesPakistan Veterinary Journal, 2004
In this study 215 buffaloes and 180 cows with the history of repeat breeding and prolonged oestrus period (>24 hours) were used. All of the animals had repeated at least twice. A total of 95 animals (50 buffaloes and 45 cows) were inseminated once, 12-18
