The main aim of this work is to detect metabolites in the brain by means of nuclear magnetic resonance spectroscopy. We were mostly interested by glutathione (GSH) and more particularly by its cysteine part which forms a strongly coupled ABX spins system. ...
When preadipocytes reenter the cell cycle, PPAR gamma expression is induced, coincident with an increase in DNA synthesis, suggesting the involvement of the E2F family of cell cycle regulators. We show here that E2F1 induces PPAR gamma transcription during ...
The invention concerns novel constructs and novel vectors for the targeted and inducible expression of genes. It describes in particular novel hybrid promoters and their use for the expression of genes in hepatic cells, in vitro, ex vivo or in vivo ...
A general method for covalent labeling of fusion proteins in vivo that complements the existing methods for protein labeling in vivo and in vitro is presented. This new method might lead to new ways of studying and manipulating proteins in living cells. Co ...
The metrics used, thus far, to assess bioartificial organ function are shown to be subjective and requiring validation. Therefore, four categories of correlations are proposed based on, respectively, device, in vitro and in vivo evaluations, and clinical f ...
A prototype miniaturized Total Chemical Analysis System (μTAS) has been developed and applied to on-line monitoring of glucose and lactate in the core blood of anaesthetized dogs. The system consists of a highly efficient microdialysis sampling interface s ...
Two methods for measuring the optical properties of tissue, i.e. reduced scattering and absorption coefficient, were developed. The first one was designed for in vitro investigations. It is based on the measurement of the spatially resolved transmittance t ...
Mounting evidence from in vitro experiments indicates that lactate is an efficient energy substrate for neurons and that it may significantly contribute to maintain synaptic transmission, particularly during periods of intense activity. Since lactate does ...
Neutralizing antibodies are necessary and sufficient for protection against infection with vesicular stomatitis virus (VSV). The in vitro neutralization capacities and in vivo protective capacities of a panel of immunoglobulin G monoclonal antibodies to th ...
Photoemission spectroscopy now reaches a lateral resolution in the submicrometer range. It is possible, therefore, to perform chemical analysis in the microscopic domain required for life-science experiments. We present a successful test of this approach, ...
