Invited Speaker / Conférencier invité

There is a long tradition of using applied physics to improve medicine. Over the years, several new treatments and new diagnostic tools have been developed by physicists. However the clinical world is much different from the laboratory. Thus, even if there are numerous opportunities for physicists in the field of medicine it can sometimes be challenging to seize them.

In this context, this...

1758. During eye growth, defocus reduces until optical blur is similar to the resolution of the cone photoreceptors

Purpose Emmetropization is an active process of reduction of defocus, regulated by the optical image on the retina. Rather than the value of defocus approaching zero, a non-zero error has been reported in humans and by us in an animal models. Here we explore the relationship between optical blur and cone photoreceptor sampling in the growing chick eye with and without imposed defocus...

Amyloid-beta (A$\beta$ ) peptides are 36 to 43 amino acid residues, implicated by the amyloid cascade hypothesis as one of the cause of Alzheimer’s disease (AD). In the brain, A$\beta$ forms small peptide aggregates, called oligomers, leading to $\beta$-sheet fibrils that, with time, forms the 3D amyloid plaque that is the hallmark of AD. The structure of fibrils consists of parallel and/or...
