From Doppler to speckle variance measurements in optical coherence tomography

A short-review of optical coherence tomography (OCT) technologies employed to evaluate and image flow and tiny movements is presented. Over the time, the progress of OCT from time domain to spectral (Fourier) domain SD-OCT has led to new approaches in measuring flow and tissue (object) vibration. In the present document, several procedures are presented of what is known today as OCTA, used to visualize tiny vessels in the human retina and replacing the need for injection in angiography. These methods are now extended to measurements of minuscule spatial variations due to action potential, cell division or tissue deformation in elastography

Development of Gold–Page: Towards the Electrophoretic Analysis of Sulphurous Biopolymers

The prevalence; distinctive reactivity and biological significance of sulphur-based groups in proteins and nucleic acids means that analysis of sulphur is of prime importance in biochemistry, biotechnology, and medicine. We report steps in the development of a method to aid in the detection of these moieties using gold nanoparticles as adjuncts in polyacrylamide gel electrophoresis (Gold-PAGE)

Supercontinuum applications in high resolution non invasive optical imaging

Progress will be presented in adapting supercontinuum sources to a variety of applications with emphasis on signal processing procedures. These are customised to alleviate noise and take full advantage of the large bandwidth and large power spectral density of modern supercontinuum sources

Les caroténoïdes (amis ou ennemis?)

Les caroténoïdes sont des micronutriments offerts généreusement par notre milieu naturel. Ils suivent le métabolisme des lipides alimentaires et sont ainsi d'absorption rapide par nos organismes humains et constituent des précurseurs " santé " , destinés à la prévention de nombreuses maladies chroniques telles les maladies cardiovasculaires, infectieuses ou cancers, considérées comme les plus redoutables. Ils peuvent représenter une corde supplémentaire à l'arc thérapeutique d'autant que les voies de la recherche les concernant , sont largement approfondies. Ils ne sont cependant pas dénués de toxicité , c'est pourquoi le pharmacien d'officine a le souci d'évaluer les risques d'automédications anarchiques et de prodiguer alors un conseil judicieux dirigé vers une utilisation raisonnée.TOULOUSE3-BU Santé-Centrale (315552105) / SudocTOULOUSE3-BU Santé-Allées (315552109) / SudocSudocFranceF
