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.

Rhinoplasty in Middle Eastern Patients.

Rhinoplasty in patients of Middle Eastern origin requires complete understanding of nasal morphology and an individualized approach to create a racially congruent and aesthetically pleasing outcome. In this article, common anatomic features and characteristics and detailed steps, surgical techniques, and operative maneuvers that can lead to predictable outcome in rhinoplasty of Middle Eastern patients are discussed.

Superior rhinoplasty outcomes with precise nasal osteotomy: an individualized approach for maintaining function and achieving aesthetic goals.

Background: Although frequently performed in rhinoplasty, nasal osteotomies have been unpredictable in consistently controlling postoperative alterations in bony morphology in many patients. Consequently, a detailed algorithm for an individualized approach to osteotomy is needed to achieve superior aesthetic and functional outcomes.

Objectives: The authors aimed to propose a component-oriented and individualized approach for nasal osteotomy in rhinoplasty.
