Magnetic actuation of otoliths allows behavioral and brain-wide neuronal exploration of vestibulo-motor processing in larval zebrafish.

The vestibular system in the inner ear plays a central role in sensorimotor control by informing the brain about the orientation and acceleration of the head. However, most experiments in neurophysiology are performed using head-fixed configurations, depriving animals of vestibular inputs. To overcome this limitation, we decorated the utricular otolith of the vestibular system in larval zebrafish with paramagnetic nanoparticles.

A simple method to make, trap and deform a vesicle in a gel.

We present a simple method to produce giant lipid pseudo-vesicles (vesicles with an oily cap on the top), trapped in an agarose gel. The method can be implemented using only a regular micropipette and relies on the formation of a water/oil/water double droplet in liquid agarose. We characterize the produced vesicle with fluorescence imaging and establish the presence and integrity of the lipid bilayer by the successful insertion of [Formula: see text]-Hemolysin transmembrane proteins.

[Electroencephalograms (EEG) in 250 patients with epilepsy in a cysticercosis endemic area in Burundi].

Objectives: This work aimed at describing EEG abnormalities in epileptic patients living in areas endemic for cysticercosis, underlining the electroclinical correlations and discussing the interest of EEG examination in this context.

Methods: During a case-control study, 250 EEGs from patients with epilepsy were recorded with a portable system. Types of seizures were assessed clinically and from information obtained through a standardised questionnaire, and along with EEG were related to the results of cysticercosis serological tests.

[Comparison of sociocultural attitudes towards epilepsy in Limousin (France), in Togo and in Benin (Africa)].

Sociocultural attitudes continue to have a negative impact on management of epilepsy in many African countries and in a few advanced countries. The purpose of this study was to compare attitudes toward epilepsy in France and two African nations: Togo and Benin. A total of 305 epileptic patients over 18 years of age were interviewed using the same quantitative questionnaire about their beliefs, knowledge attitudes and practices regarding their disease.

Is the morning peak of acute myocardial infarction's onset due to sleep-related breathing disorders? A prospective study.

Many studies have shown that the risk of experiencing a myocardial infarction (MI) is increased during the first hours of the morning. Sleep apnea syndrome (SAS) is associated with an enhanced adrenergic activity, prolonged a few hours after awakening. We aimed at assessing whether sleep breathing disorders could be a culprit for the morning excess rate of MI.
