Cloning, heterologous expression, and activity analysis of NADPH-cytochrome P450 reductase from the Chinese white rabbit

open access: yesBiotechnology & Biotechnological Equipment, 2018
Cytochrome P450 reductase (CPR) is an integral component of the P450 oxidoreductase system (P450s). It serves as the electron donor for most cytochromes in P450s, which are involved in the metabolism of foreign compounds and the synthesis of endocrine ...

Modélisation, faire et dire du faire pour des informaticiens engagés dans une démarche de VAE

open access: yesActivités, 2010
The accreditation of work experience introduces a rift between training and qualification. The fact that qualification can be acquired without undergoing training raises the sensitive issue of how experience should be assessed.

Longitudinal Analysis of Strike Activity [PDF]

open access: yes
This paper presents evidence on two aspects of strike activity associated with the renegotiation of union contracts: the effects of contract characteristics on dispute probabilities; and the effects of lagged strike outcomes on the incidence and duration

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Switching regressions and activity analysis. [PDF]

open access: yes
We study the use of switching regression models to characterize the coefficients in linear production technologies with a finite number of activities. Maximum likelihood-based methods are proposed and different switching specifications are discussed. The
