Getting the Inside Tract: New Frontiers in Zebrafish Digestive System Biology

New Frontiers for Organismal Biology

June 2013 / Vol. 63 No. 6 www.biosciencemag.org have generated extensive fundamental knowledge that now has us superbly positioned for “returning to the organism” (Stillman et al. 2011). The challenge is to extend, integrate, and exploit the insights from “outward” and “inward” gene-oriented biology to develop a deeper understanding of individual organisms’ higher-order emergent characteristics...

Digestive system anatomy of the Acipenser persicus: New features

Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...

New frontiers in type III secretion biology: the Chlamydia perspective.

Members of the order Chlamydiales comprise a group of exquisitely evolved parasites of eukaryotic hosts that extends from single-celled amoeba to mammals. The most notable are human pathogens and include the agent of oculogenital disease Chlamydia trachomatis, the respiratory pathogen C. pneumoniae, and the zoonotic agent C. psittaci. All of these species are obligate intracellular bacteria tha...
