Surfing USA: an epidemiological study of surfing injuries presenting to US EDs 2002 to 2013.

Introduction: Surfing is a popular recreational and competitive sport in the United States and worldwide. Previous studies indicate surfers are frequently injured, but most studies are survey based, and little is known about surfing injuries that present to emergency departments (EDs).

Aims: This study examines the epidemiology of surfing injuries presenting to US EDs.

Hetero-arylboroxines: the first rational synthesis, X-ray crystallographic and computational analysis.

A novel series of hetero-arylboroxines were synthesized and structurally characterized by X-ray diffraction, NMR and computational analysis. The solid-state structures of the hetero-arylboroxines represent the first report of AB(2)-type hetero-arylboroxines.
