Intraoperative brain deformations decrease accuracy in image-guided neurosurgery. Approaches to quantify these deformations based on 3-D reconstruction of cortectomy surfaces have been described and have shown promising results regarding the extrapolation to the whole brain volume using additional prior knowledge or sparse volume modalities. Quanti...

Important information on cellular physiology can be obtained by directly observing living cells. The nucleus, and the chromatin within, is of particular interest to many researchers. Monitoring the behavior of specific DNA loci in the living cell is now commonly achieved through the insertion of binding sites for fluorescently tagged proteins at th...

We confirm a significant miss rate for polyps or adenoma during colonoscopy. Detection of flat polyps is an issue that must be focused on to improve the quality of colonoscopy.

The hormonal regulation of feeding behaviour is well known in vertebrates, whereas it remains poorly understood in insects. Here, we report that the takeout gene is an essential component of nutritional homeostasis in Drosophila. takeout encodes a putative juvenile hormone (JH) binding protein and has been described as a link between circadian rhyt...

Although normal subjects do not move during REM sleep, patients with Parkinson's disease may experience REM sleep behaviour disorder (RBD). The characteristics of the abnormal REM sleep movements in RBD have, however, not been studied. We interviewed one hundred consecutive non-demented patients with Parkinson's disease and their bed partners using...
In spite of the poor agreement between the written and the video questionnaires, the prevalence of asthma symptoms estimated using the video questionnaire confirms that asthma is an important public health problem in Maputo.

Mammalian locomotion is characterized by the use of asymmetrical gaits associated with extensive flexions and extensions of the body axis. Although the impact of sagittal spine movements on locomotion is well known, little information is available on the kinematics of spinal motion. Intervertebral joint movements were studied in two metatherian and...

We report the case of a male aged 2 years 6 months with left temporal lobe epilepsy who presented with ictal bradycardia syndrome leading to asystole. The clinical presentation was remarkable for the occurrence of clustering syncope. A seizure was recorded on a video electroencephalogram- electrocardiogram and analyzed. A cardiac pacemaker was impl...

Insects, like vertebrates, exhibit spatially complex locomotor activity patterns when foraging or navigating. Open field studies recently showed that Drosophila avoids central zones and stays at the periphery, an effect that can be interpreted as centrophobism and/or thigmotaxis. In this study, we further characterized this phenomenon and studied t...

The aim of the present experiment was to study the central control of posture and movement coordination. Subjects' task was voluntarily to raise their arms in response to a visual signal, this movement generating an unloading in which the weight of the load (0 gm, 1500 gm, 3000 gm, or 4500 gm) was known in advance. Thus, subjects could predict the ...
