The aim of the present experiment was to study the influence of +Gz acceleration (head-to-foot inertial forces) onset on cerebral oxygenation changes (cerebral oxy- and deoxy-hemoglobin) and cerebral blood volume (CBV) in order to evaluate the role o

We demonstrate that a low cost interferometric set-up and the analysis of the speckle fluctuations due to a wavelength modulated continuous source can be used to perform time-resolved measurements of the light scattered by a turbid medium. This metho

The aim of this paper is to solve the diffusion equation in the case of two semi-infinite homogeneous scattering and absorbing media separated by a flat interface when a light source S is placed in one of these media. We present here a new approach w

To determine the external force that induces maximal deoxygenation of brachioradialis muscle 32 trained male subjects maintained isometric contractions using the elbow flexor muscles up to the limit time (isotonic part of the isometric contraction, I

We assessed the ability of laser-induced autofluorescence spectroscopy to distinguish neoplastic urothelial bladder lesions from normal or nonspecific inflammatory mucosa. Three different pulsed laser excitation wavelengths were used successively: 30

Nous avons mis au point une methode de mesure fondee sur l'analyse de la nappe de reflectance resolue dans le temps et dans l'espace afin de mesurer en temps reel, de facon non invasive et in vivo, les coefficients optiques des tissus biologiques. Le

L'hypoxie est un facteur de radioresistance dans le traitement des tumeurs solides. Pour radiosensibiliser ces tumeurs, on peut faire inhaler du carbogene et il est essentiel d'irradier lorsque l'augmentation de l'oxygenation tumorale creee par cette

The feasibility of routine real-time clinical detection of precancerous lesions such as severe dysplasia and carcinoma in situ (CIS) by laser induced autofluorescence (LIAF), that is without the use of exogenous fluorescent marker, has been recently

A difficulty in nonmuscle invasive bladder cancers is the diagnosis of flat and small lesions during white light cystoscopy. We assessed a prototype that measures ultraviolet laser induced autofluorescence for endoscopic detection of nonmuscle invasi
