Intertissue mechanical interactions shape the olfactory circuit in zebrafish.

While the chemical signals guiding neuronal migration and axon elongation have been extensively studied, the influence of mechanical cues on these processes remains poorly studied in vivo. Here, we investigate how mechanical forces exerted by surrounding tissues steer neuronal movements and axon extension during the morphogenesis of the olfactory placode in zebrafish. We mainly focus on the mechanical contribution of the adjacent eye tissue, which develops underneath the placode through extensive evagination and invagination movements.

Development of a human skeletal micro muscle platform with pacing capabilities.

Three dimensional engineered culture systems are powerful tools to rapidly expand our knowledge of human biology and identify novel therapeutic targets for disease. Bioengineered skeletal muscle has been recently shown to recapitulate many features of native muscle biology. However, current skeletal muscle bioengineering approaches require large numbers of cells, reagents and labour, limiting their potential for high-throughput studies.

Automated Buildup of Biomimetic Films in Cell Culture Microplates for High-Throughput Screening of Cellular Behaviors.

An automatic method is established for layer-by-layer (LbL) assembly of biomimetic coatings in cell culture microplates using a commercial liquid-handling robot. Highly homogeneous thin films are formed at the bottom of each microwell. The LbL film-coated microplates are compatible with common cellular assays, using microplate readers and automated microscopes.

[Rhegmatogenous retinal detachment and hypertension: Schwartz-Matsuo syndrome].

Purpose: To assess the usefulness of electron microscopy of the aqueous cells when confronted with the clinical association of rhegmatogenous retinal detachment after trauma, high intraocular pressure (IOP) and aqueous cells.

Method: We report a clinical history of a 50-years-old man who had ocular trauma with perforation in 1944, intraocular lens for traumatic cataract in 1988, Yag capsulotomy in 1993 and retinal detachment with oral dialysis, high IOP and aqueous cells in anterior chamber in 1995. During the surgical therapy we performed an anterior chamber puncture to analyse the aqueous cells.

[Treatment with cyclosporin A, with low doses, in high-risk penetrating keratoplasties. A bi-centric study of 90 cases].

Purpose: Evaluation of cyclosporin-A in prevention of immune reaction in high-risk penetrating keratoplasties.

Material And Methods: Cyclosporin A was given to 45 corneal allograft recipients, 5 mg/kg/j (cyclosporinemy between 100 and 150 ng/l), for three months following surgery. 45 controls have undergone penetrating keratoplasty during the same period.
