Identification of U-Bundles Based on Sulcus Morphology
It is a fact that the brain cortical folding pattern morphology is specific to each human being. Neuroanatomists think that the folding pattern is strongly related to brain connectivity [1]. As each folding varia...

A framework based on sulcal constraints to align preterm, infant and adult human brain images acquired in vivo and post mortem
Robust spatial alignment of post mortem data and in vivo MRI acquisitions from different ages, especially from the early developmental stages, into standard spaces is still a bottleneck hampering easy comparis...

Linking morphological and functional variability in hand movement and silent reading
It is generally accepted in neuroscience that anatomy and function go hand in hand. Accordingly, a local morphological variability could lead to a corresponding functional variability. In this study, we tested...

Automatic Inference of Sulcus Patterns Using 3D Moment Invariants
The goal of this work is the automatic inference of frequent patterns of the cortical sulci, namely patterns that can be observed only for a subset of the population. The sulci are detected and identified usin...

MR Diffusion-Based Inference of a Fiber Bundle Model from a Population of Subjects
This paper proposes a method to infer a high level model of the white matter organization from a population of subjects using MR diffusion imaging. This method takes as input for each subject a set of trajecto...

Anatomically Constrained Surface Parameterization for Cortical Localization
We present here a method that aims at defining a surface-based coordinate system on the cortical surface. Such a system is needed for both cortical localization and intersubject matching in the framework of ne...

Fiber Tracking in q-Ball Fields Using Regularized Particle Trajectories
Most of the approaches dedicated to fiber tracking from diffusion-weighted MR data rely on a tensor model. However, the tensor model can only resolve a single fiber orientation within each imaging voxel. New e...

3D Moment Invariant Based Morphometry
This paper advocates the use of shape descriptors based on moments of 3D coordinates for morphometry of the cortical sulci. These descriptors, which have been introduced more than a decade ago, are invariant r...

Object-Based Strategy for Morphometry of the Cerebral Cortex
Most of the approaches dedicated to automatic morphometry rely on a point-by-point strategy based on war** each brain towards a reference coordinate system. In this paper, we describe an alternative object-b...

Effect of a long-duration physical exercise on fat cell lipolytic responsiveness to adrenergic agents and insulin in obese men
OBJECTIVE: The aim of the study was to investigate whether a long-lasting bout of exercise modifies the lipolytic β- and antilipolytic-α2-adrenergic effect and the antilipolytic effect of insulin in obese subject...

A Mean Curvature Based Primal Sketch to Study the Cortical Folding Process from Antenatal to Adult Brain
In this paper, we propose a new representation of the cortical surface that may be used to study the cortex folding process and to recover foetus sulcal roots usually burried in the depth of adult brains. This...

Recent developments on lipolysis regulation in humans and discovery of a new lipolytic pathway
In man, the major hormones controlling the lipolytic function are insulin (inhibition of lipolysis) and catecholamines (stimulation of lipolysis). Catecholamines are of major importance for the regulation of l...

Decrease of subcutaneous adipose tissue lipolysis after exposure to hypoxia during a simulated ascent of Mt Everest
The purpose of this study was to examine the effects of prolonged hypoxia on adipose tissue lipolysis, in relation to the weight loss usually observed at high altitude. Eight male subjects were exposed for 31...

Endurance training increases the β-adrenergic lipolytic response in subcutaneous adipose tissue in obese subjects
OBJECTIVE: The aim of this study was to assess, by longitudinal follow-up, the influence of aerobic training on the in vivo lipolytic activity of adipose tissue in obese male subjects.

Pharmacodynamic effects of chronic yohimbine treatment in healthy volunteers
The effects of 14 days of treatment with the alpha2-adrenoceptor antagonist yohimbine on cardiovascular parameters (blood pressure and heart rate), plasma catecholamines, insulin and non-esterified fatty acids (N...

An optical study of thin interfacial liquid films using total reflection of light
The light totally reflected at the interface between a glass prism and a liquid (water) of lower index can be partly transmitted as a droplet of liquid of larger index (oil) approaches this interface. By using...

Comparaison biochimique de quatre espèces de copépodes planctoniques de Méditerranée nord-occidentale à partir des enzymogrammes des estérases, de la leucine aminopeptidase, de la phosphatase alcaline, de la malate déshydrogénase et de l'enzyme malique
Four copepod species (Acartia clausi, Centropages typicus, Temora stylifera, Calanus helgolandicus) from the northwest Mediterranean were subjected to electrophoresis on polyacrylamide gel in an attempt to distin...

Impact d'une pollution d'origine urbaine sur les activités enzymatiques de deux copépodes planctoniques (Acartia clausi et Centropages typicus)
The effect of urban pollution on the enzymatic activities of two copepod species, Acartia clausi and Centropages typicus, was studied in the Marseille area (main sewage output of Cortiou) from May 1980 through Ju...
