Catch-Up Saccades in Vestibulo-Ocular Reflex Deficit: Contribution of Visual Information?

Ear Hear

December 2024

Institut national de la santé et de la recherche médicale, U1028, Centre National de Recherche Scientifique, UMR5292, Lyon Neuroscience Research Center, Integrative Multisensory Perception and ACTion Team, Lyon, France.

Objectives: Catch-up saccades help to compensate for loss of gaze stabilization during rapid head rotation in case of vestibular deficit. While overt saccades observed after head rotation are obviously visually guided, some of these catch-up saccades occur with shorter latency while the head is still moving, anticipating the needed final eye position. These covert saccades seem to be generated based on the integration of multisensory inputs.

Allorecognition Unveiled: Integrating Recent Breakthroughs Into the Current Paradigm.

Transpl Int

November 2024

Centre International de Recherche en Infectiologie, INSERM U1111, Université Claude Bernard Lyon I, CNRS UMR5308, Ecole Normale Supérieure de Lyon, University Lyon, Lyon, France.

In transplantation, genetic differences between donor and recipient trigger immune responses that cause graft rejection. Allorecognition, the process by which the immune system discriminates allogeneic grafts, targets major histocompatibility complex (MHC) and minor histocompatibility antigens. Historically, it was believed that allorecognition was solely mediated by the recipient's adaptive immune system recognizing donor-specific alloantigens.

Article Synopsis
  • A carotid web (CaWeb) is a rare fibrous tissue growth in the carotid bulb, often leading to ischemic strokes in younger individuals, especially young women.
  • Recent reviews reveal that traditional diagnostic criteria may miss CaWebs since many patients show less than 50% stenosis on ultrasound, complicating their detection and management.
  • Current treatment approaches for symptomatic CaWebs focus on procedures like endarterectomy or stenting, but there are still no standardized guidelines for handling asymptomatic cases, making ongoing research crucial.
