E-Cigarette and Liquid Nicotine Exposures Among Young Children.

Objectives: To investigate exposures to liquid nicotine (including electronic cigarette devices and liquids) among children <6 years old in the United States and evaluate the impact of legislation requiring child-resistant packaging for liquid nicotine containers.

Methods: Liquid nicotine exposure data from the National Poison Data System for January 2012 through April 2017 were analyzed.

Results: There were 8269 liquid nicotine exposures among children <6 years old reported to US poison control centers during the study period.

A sequence polymorphism in MSTN predicts sprinting ability and racing stamina in thoroughbred horses.

Variants of the MSTN gene encoding myostatin are associated with muscle hypertrophy phenotypes in a range of mammalian species, most notably cattle, dogs, mice, and humans. Using a sample of registered Thoroughbred horses (n = 148), we have identified a novel MSTN sequence polymorphism that is strongly associated (g.66493737C>T, P = 4.
