Le cancer du sein est le type de cancer le plus répandu dans le monde et l’une des principales causes de décès chez les femmes. Une étude impliquant des chercheurs de l’Université Paris-Saclay, de l’Inserm et d’INRAE vient d’établir un lien entre le travail de nuit et l’augmentation du risque de cancer, suggérant que la perturbation du rythme circadien pourrait rendre les tumeurs plus agressives.
L’imagerie ultrasonore ultrarapide a récemment été proposée pour suivre l’activité cérébrale dans la profondeur du cerveau.
When it comes to recognizing a melody or understanding a spoken sentence, the human brain does not mobilize its hemispheres in an equivalent way. A team of researchers has been able to show that, due to different receptivities to the components of sound, the left auditory cortex neurons participate in the recognition of speech, whereas the right auditory cortex neurons participate in that of music.
The leading cause of mortality worldwide, cardiovascular diseases claim over 17 million lives each year, according to World Health Organization estimates. To open up new research avenues into this serious public health problem, Inserm researcher Nicolas L’Heureux and his team are developing “human textiles” from collagen in order to repair damaged blood vessels.
Using cerebral imaging, connections between the various brain regions can be visualized. These connections form a veritable “map” of its structure, specific to each individual. Knowledge of these “maps” is enough to predict not just brain function but also the potential development and treatment of neurological diseases.
Restoring sight to patients with age-related macular degeneration (AMD) or retinitis pigmentosa has become an increasingly likely prospect over recent years, with many researchers working to develop an artificial retina.
Chaque année en France, 46 000 personnes sont victimes d’un arrêt cardiaque. Des chercheurs proposent une nouvelle approche pour mieux les prendre en charge et mieux appréhender leurs possibles conséquences. Elle repose sur une technique basée sur le froid et la ventilation liquide.
One hypothesis put forward to explain the repetitive behaviors of people with Autism Spectrum Disorder is a lack of cognitive flexibility. However, this may well not be the case. A recent study used MRI to track the brain activity of autistic and non-autistic subjects faced with situations similar to those that cause problems in the daily lives of people with the disorder. Their findings, published in Brain and Cognition, suggest that the inflexibility of autistic individuals is actually the result of a strategy used to avoid socio-emotional situations. This research, which suggests now considering the cognitive and socio-emotional domains as closely linked rather than dissociated, opens up new avenues in the understanding and management of autism.
A research team used 3D culture to develop adipose tissue organoids (or adipospheres) – small cellular units that mimic the characteristics and organization of adipose tissue as it presents in vivo.
Des recherches démontrent dans un modèle de souris au foie humanisé, que le VHD est capable in vitro et in vivo d’utiliser l’enveloppe d’autres virus que celle du VHB, comme celle du virus de l’hépatite C et de virus d’autres genres, comme celui de la dengue.
