Whisker spot patterns: a noninvasive method of individual identification of Australian sea lions ().

Reliable methods for identification of individual animals are advantageous for ecological studies of population demographics and movement patterns. Photographic identification, based on distinguishable patterns, unique shapes, or scars, is an effective technique already used for many species. We tested whether photographs of whisker spot patterns could be used to discriminate among individual Australian sea lion ().

Association of the interleukin-23 receptor gene variant rs11209026 with Crohn's disease in German children.

Improved performance of a rapid office-based stool test for detection of Helicobacter pylori in children before and after therapy.

A modified version of a rapid office based one-step monoclonal immunoassay for detection of Helicobacter pylori antigen in stool samples from children was evaluated against biopsy specimen-based methods and compared to a monoclonal enzyme immunoassay using the same antigen. Blinded stool samples from 185 children (0.3 to 18.
