Pavement ant extract is a chemotaxis repellent for C. elegans.

Ant behavior relies on a collection of natural products, from following trail pheromones during foraging to warding off potential predators. How nervous systems sense these compounds to initiate a behavioral response remains unclear. Here, we used chemotaxis assays to investigate how ant compounds are detected by heterospecific nervous systems.

Preservation of anterior capsule during vitrectomy and lensectomy for retinal detachment with proliferative vitreoretinopathy.

Purpose: To report a series of 15 eyes with rhegmatogenous retinal detachment and proliferative vitreoretinopathy (PVR) or at high risk for advanced PVR, which underwent pars plana vitrectomy (PPV) and lensectomy (PPL) with preservation of the anterior capsule.

Design: Retrospective noncomparative case series.

Participants: Fifteen consecutive patients with retinal detachment and varying degrees of PVR in one eye.
